FIELD OF THE INVENTION

The invention is generally related to pneumatic material transfer systems, such as vacuum transport systems, especially to the collection and transfer of material, such as the transfer of industrial materials or economic10 waste or recyclable material.

BACKGROUND OF THE INVENTION

Systems are known in which solid material, for example solid waste, can be moved in the pipeline by means of suction and/or transport air flow.

In these, material can be moved over long distances in the pipeline pneumatically by means of suction and/or pressure difference, typically together with transport air. The equipment is used e.g. for the transfer of material in various containers, for the transfer of domestic waste or for the transfer of other waste. It is typical for them that vacuum equipment is used to create the pressure difference needed to transport the material, where the vacuum in the transfer pipe is created with vacuum generators, such as vacuum pump25 trees or ejector equipment. The transfer pipe typically has at least one valve element, which, by opening and closing, regulates the replacement air coming into the transfer pipe. As a result, an air flow is created in the transfer pipe, with which the material can be moved. Systems are also known in which the pressure difference and/or transport air flow to the transfer pipeline can be achieved, for example, by means of a blowing arrangement. Publications FI122683B, FI124175B and WO2020/084190A1 show some pneumatic material transfer systems. One of the convenient solutions for new regional construction projects is waste management, which will work

20215248 Fri 27 -03- 2023 with a pipeline transport system. This means that sorted waste or recyclable material is sucked through underground pipes to the common waste station of the entire area. The system is clean, odorless and noiseless, and 5 more environmentally friendly than traditional waste management and a safer solution for the surrounding environment. On the other hand, some of the waste is often that which, due to its size or other quality, cannot be satisfactorily transported in a long pipeline. 10

The purpose of this invention is to provide a completely new kind of solution in connection with material transfer systems, which avoids the disadvantages of known solutions. Another purpose of the invention is to provide a solution where part of the material does not necessarily want to be transported all the way in a long transfer pipe to the waste station, but is transported to a collection tank that can be emptied separately.

SUMMARY OF THE INVENTION

The invention is based on an idea in which a pneumatic material transfer pipe is arranged, in which suction and replacement air can be arranged by regulating the conveying air flow. According to one application form, the material transfer pipe can be a transfer pipe suitable for pneumatic transport, to which vacuum devices can be used to provide suction and replacement air by regulating the transport air flow. Another material transfer arrangement can be connected to the material transfer pipe, along its length 30, which utilizes the negative pressure created in the pipeline of the first material transfer system.

According to one embodiment 35, the subject of the invention is a method for moving material in a transfer pipe pneumatically by suction, pressure difference and/or

The application forms of the method of the invention are characterized by what is mentioned in the non-independent patent claims. By arranging a second material transfer arrangement in connection with the first material transfer system, which utilizes the suction/vacuum pressure of the vacuum developer of the first material transfer system, but where the transported material can be transferred from the feed point along its own transfer pipe to its own separation device in its container, an efficient solution for the transfer and collection of the second material can be provided.

Instead of or in addition to one of the applications mentioned above or below, in the arrangement, the second transfer pipe can be mainly of a different material than the first transfer pipe. The second transfer tube can thus be adapted to another material. This makes it possible that the en15-shaped transfer pipe does not have to be adapted for another material, but can be adapted, for example, to meet the requirements for the transfer of the first material only. This can be a very significant point economically, as the transfer distances can be quite long with the first 20 material transfer systems.

Instead of or in addition to one of the applications mentioned above or below, in the arrangement, another transfer pipe can comprise a wear-resistant material, for example metal.

Instead of or in addition to one of the applications mentioned above or below, another separator device can comprise a so-called deep collection tank.

According to the third aspect, the invention can be directed to a material transfer system. The material transfer system is characterized by what is mentioned in patent claim 26. According to one embodiment, the material transfer system can comprise one or more of the above or below mentioned embodiments. According to one embodiment, the first material transfer system and/or the second material25 transfer arrangement can transfer industrial materials and/or household waste and/or recyclable material. According to one embodiment, the first material transfer system is used to transfer materials from the food industry or household waste.

The solution according to the invention has numerous significant advantages. With the help of the solutions of the invention, the disadvantages of the known technology are avoided. By using a deep collection tank as a separator device, the material transferred to the collection tank can also be efficiently stored, and the emptying of the 35 tank can be performed less often. The collection tank can be emptied by lifting the collection tank and moving the material accumulated in the tank

20215248 prh 27 -03- 2023 from the openable and closable opening arranged in the lower part of the container, for example to the container of a means of transport, such as a garbage truck. Alternatively, the container can be transported to another place to be emptied and the filled container 5 can be replaced with an empty container. The solution according to the invention can effectively combine the separator device of the pneumatic material pipe transport system and the collection tank intended for the temporary storage of the transported material. When the collection tank is so-called a deep collection tank, which is at least partially submerged below the ground level or a similar surface level, can effectively reduce the space requirement. By arranging most of the volume of the collection tank under the surface of the ground and only a small part of the visible part relative to time15, a solution for the collection tank that is well suited to the environment is obtained. Due to the large volume and the dimensions of the container, the material collected in the container collapses, i.e. compacts, so that the material can fit in the collection container in relation to more than in several small containers. According to a preferred embodiment, the deep collection tank separator device comprises a collection tank and an outer tank in which the collection tank is arranged and from which the collection tank is lifted for emptying. The solution according to the invention is suitable for use in connection with pneumatic pipe transport systems of many types of material.

When using the vacuum developing equipment to create the pressure difference and/or transport air flow needed for the transfer pipeline, the vacuum developing devices of the first transfer system can be used in connection with the material transfer system comprising the deep ke30 rag separator device of the invention to create the negative pressure needed for pneumatic material transport. Several other transfer arrangements can be arranged along the transfer pipe of the material transfer system. The system 35 thus makes it possible to share the effective operating time of the vacuum source of the first material transfer system among several other material transfer systems.

20215248 Fri 27 -03- 2023

According to the application form of the invention, it can also be thought that the vacuum source of the deep collection separator device or separator devices is, for example, a fixed vacuum pump system of a larger system, with which air flow/underpressure is used to move the material from one supply point to another separator device. This solution is particularly suitable for situations where there are several deep collection separator devices arranged along the transmission pipe of a larger system. The solution according to the invention offers the possibility of using an existing garbage truck or similar to empty the collection tank of the deep collection separator. The deep collection tank-separator device according to the invention also enables the feeding of such material into the collection tank via the opening and closing opening formed in 15, which, for example, due to its size or other characteristics, is not suitable for moving the material in a pneumatic pipe transport system. In the deep collection tank-separator device according to the invention, the duct 20 affects the flow of air in the chamber space of the separator device or in the exhaust channel by providing a control effect to the transport air in the opposite direction to its direction of rotation. With this, it is possible to significantly improve the fact that the material to be separated does not move towards the discharge channel without the transport air. In this case, for example, waste particles, such as papers or plastic films or bags, do not get into the outlet of the separation device and/or support the outlet, and a reliable deep collection tank-separator device for the pneumatic waste transfer30 system can be provided. The desired effect can be achieved by arranging the exhaust connection on the wall of the exhaust duct so that the flow of transport air from the exhaust duct to the exhaust joint is achieved mainly in a tangential direction with respect to the wall of the exhaust duct. This can be achieved, for example, by arranging the discharge joint eccentrically in the discharge channel. The deep collection separator device according to the invention is suitable for both

20215248 prh 27 -03- 2023 for material transfer systems that use a formatter, i.e. a rotary shaper, to compact and/or shape the material led from the feed points to the transfer pipeline, and for conventional pneumatic material pipe transport systems, where the material is fed from the feed point directly to the transfer pipeline.
