Description

[Technical field]

[0001] The object of the invention is a method as defined in the preamble of claim 1.

[0002] The subject of the invention is also a separating device as claimed in claim 21 for a material conveying system.

[0003] The subject of the invention is also a waste conveying system as defined in claim 36.

[0004] FIELD OF THEINVENTION This invention relates generally to pneumatic material conveying systems, such as partial-vacuum conveying systems, and more particularly to the collection and conveying of waste or recyclable materials, such as the conveying of household waste. [Background technology]

[0005] Systems are known in the art in which waste is conveyed in pipes using suction and / or air conveying. In these systems, waste is moved long distances in pipes pneumatically with conveying air using suction and / or pressure difference. These devices are used in particular for conveying waste in different facilities, for conveying household waste or for conveying other waste. For these systems, it is typical that a partial vacuum device is used to create a pressure difference, in which a partial vacuum is created in the conveying pipe by a partial vacuum generator, such as a vacuum pump or an evacuation device. The conveying pipe typically comprises at least one valve means, by opening and closing this valve means the exchange air entering the conveying pipe is regulated. One of the easy-to-use solutions for new community building projects is waste management operating with a pipe conveying system. In these solutions, the separated waste is sucked along buried pipes to a waste station common to the whole community. This system is clean, odorless, noiseless, environmentally friendly and safer in terms of the surrounding environment than traditional waste disposal. In the waste station there is typically a separation device in which the conveyed material is separated from the conveying air, which is then fed into an outlet pipe via possible filters. Typically, a number of separation devices and / or material containers are used in relatively small systems, into which the material conveyance is fed. Such devices and / or containers are used, for example, when multiple material fractions are intended to be conveyed, or when the volume of the amount of material to be conveyed makes it prudent to use multiple separation devices and / or material containers. In pneumatic material conveying systems, for example, where household waste or recyclable materials are conveyed, one of the problems is that sometimes light-weight but high-surface-area material particles, such as loose paper or plastic, are not necessarily separated from the conveying air in the separation device, but instead reach the filter after the separation device in the downstream direction of the conveying air. As a result, for example, more filters are required or the filters may become clogged.Attempts have been made to provide various solutions to this problem, but the problem is that in many cases they are inadequate for small systems.

[0006] [Patent Document 1] International Publication No. 2011 / 151522 [Patent Document 2] International Publication No. 2014 / 029903 [Patent Document 3] International Publication No. 2014 / 135746 Summary of the Invention [Problem to be solved by the invention]

[0007] The object of the present invention is to provide a new type of solution in relation to material conveying systems, with which the drawbacks of the solutions known in the art are avoided. Another object of the present invention is to provide a solution for relatively small systems in which an effort is made to reduce the number of components, for example the use of various filters, without compromising the functionality of the system. Yet another object of the present invention is to provide a solution in which pneumatic emptying of the input point and emptying of the collection vessel can be performed flexibly and even independently of each other. [Means for solving the problem]

[0008] The invention is based on the idea that material is conveyed in a selected manner from an input point in a transport air flow in a material conveying pipe to one of at least two separating devices, in such a way that at least one of said separating devices is configured to act as a standby separating device for the second separating device. The conveying air, and possibly the material particles remaining therein, having passed through the first separating device, is fed into this separating device, which acts as a standby separating apparatus. In the presented separating device arrangement, the first and second separating devices can be intended to function mainly as separating devices for different materials or for the same material.

[0009] The method according to the invention is characterized by what is disclosed in the characterizing part of claim 1.

[0010] The method according to the invention is also characterized by what is disclosed in claims 2-20.

[0011] A separation device assembly according to the invention is characterized by what is disclosed in claim 21.

[0012] The separation device assembly according to the invention is also characterized by what is disclosed in claims 22-35.

[0013] The waste conveying system according to the invention is characterized by what is disclosed in the characterizing part of claim 36.

[0014] The solution according to the invention has a number of important advantages: By using the invention the disadvantages of the solutions according to the prior art can be avoided.

[0015] By using a separation device assembly according to an embodiment of the invention, the separation of material particles from the conveying air in the standby separation device can be improved. Thereby, it is possible to significantly improve the prevention of the material to be separated from the conveying air via the standby separation device of the separation device assembly towards the discharge channel leading to the suction side of the partial vacuum source. In this case, it is possible to more effectively ensure that waste particles, such as paper or plastic films or bags, remain in the separation device of the separation device assembly. Thus, an operationally reliable separation device assembly for a pneumatic waste conveying system can be achieved. In the separation device of the separation device assembly according to an embodiment of the invention, the flow of the conveying air in the chamber space or in the discharge channel of the separation device can act by providing a guiding effect of the conveying air in the opposite direction with respect to its rotation direction. Thereby, it is further possible to significantly improve the prevention of the material to be separated from the container space of the separation device towards the discharge channel together with the conveying air. In this case, waste particles, such as paper or plastic films or bags, are not easy to get into the discharge opening of the separation device and / or block the discharge opening, and an operationally reliable separation device for use in the separation device assembly can be achieved. The desired effect can be achieved by arranging the discharge branch on the wall of the discharge channel such that the flow of the conveying air from the discharge channel to the discharge branch is mainly tangential with respect to the wall of the discharge channel. This can be achieved, for example, by arranging the discharge branch eccentrically in the discharge channel. The arrangement of the separation device according to the invention is suitable both for material conveying systems in which a formatter, i.e. a rotary shaper, is used to compact and / or shape the material to be fed from the input point into the conveying pipe, and for normal pneumatic pipe conveying systems for material in which the material is fed directly into the conveying pipe from the input point. By using a deep collection vessel as a separation device, the material conveyed in the collection vessel is efficiently stored and the vessel has to be emptied less frequently.Emptying the collection vessel can be carried out by lifting the collection vessel and transferring the material collected in the vessel through an openable opening arranged at the bottom of the vessel into the vessel of a transport means such as a garbage truck. The transport means can comprise a press for compressing and densifying the material and a hoist for lifting the collection vessel. With the solution according to the invention, the separation device of a pneumatic piping transport system for the material and a collection vessel intended for temporary storage of the transported material can be efficiently combined. The space requirements can be efficiently reduced when the collection vessel is a so-called deep collection vessel, which is buried at least partially below the surface level of the ground or a corresponding surface level. By arranging most of the volume of the collection vessel below the ground surface and leaving a relatively small part visible, an environmentally well suited solution for the collection vessel is achieved. Due to the large volume and dimensions of the vessel, the collected material settles, i.e. is compacted, in which case a relatively large amount of material can fit in this collection vessel compared to a number of smaller vessels. When the collection bin is arranged deep in the ground, the deep collection bin remains cool even in summer, and there is less harmful odor that may be generated by the waste. According to a preferred embodiment, the deep collection bin-separation device comprises a collection bin and an outer container, in which the collection bin is arranged and from which the collection bin is lifted for emptying. A separation device may be used in the arrangement of the separation device according to the invention, which also offers the possibility of feeding, via an openable input opening formed in the collection bin, a type of material that is not suitable for conveying in a pneumatic piping conveying system for the material, for example due to its size or other characteristics. According to an embodiment of the invention, it is also contemplated that the partial vacuum source arranged in the deep collection separation device or close to the separation device is, for example, a fixed suction pump container or a corresponding one, which processes the air flow / partial vacuum for conveying the material from the input point into the separation device. This solution is particularly suitable in situations where there are a large number of interconnected deep collection separation devices. The solution according to the invention offers the possibility of using existing garbage trucks or a corresponding one to empty the collection bin of the deep collection separation device.The solution according to the invention also makes it easy to realize a solution in which the separation device is arranged in different locations, such as outdoors, and the partial vacuum generator and the associated equipment are arranged in the interior space of a building. A mobile partial vacuum generator can be effectively used to provide the partial vacuum required for the air conveying of the material in connection with a material conveying system comprising the deep recovery separation device of the invention. In this case, a dedicated fixed partial vacuum generator is not required for each material conveying system. The system therefore makes it possible to divide the effective operating time of the partial vacuum source between a number of material conveying systems. The solution according to the invention makes it possible to effectively use different frequencies for the operation of the partial vacuum source and for emptying the containers. The separation device assembly according to the invention is suitable for use in connection with a number of different types of separation devices. Various containers in which the material is separated from the conveying air can be used in this arrangement. The containers may depend on the application point with regard to their shape and dimensions. Separation devices and / or material containers can be used that are removably fastened to the material conveying pipes and to the pipes for circulating the conveying air through the separation device and / or material container.

[0016] In the following, the invention will be explained in more detail with the help of an embodiment with reference to the attached drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] In the figures, a representation is used for the valves in which open paths through the valve are marked with a white color and closed paths are marked with a black color. In addition, in the figures, the diagrammatic direction of the movement of the conveying air a and / or material in different operating states is presented by means of arrows. In the text, the terms "pipe", "channel", "branch" generally refer to a material path or a part thereof and / or a conveying air path or a part thereof. The paths may typically be pipes or hoses, for example.

[0019] In the following, the operation of one separation device will first be presented at a general level with the aid of Fig. 1, which shows one partially sectioned separation device 10B of a pneumatic material conveying system. The separation device 10B is operatively adapted to be connected to a material conveying pipe 100B of the pneumatic material conveying system, through which the material W B The material W is fed into the separation device 10B from the input opening 14' together with the conveying air a. In the separation device 10B, B is separated from the conveying air a. The separation device 10B is operatively adapted to be connected, for example via a suction tube 25, to a device for providing a conveying air flow of a pneumatic material conveying system, such as a partial vacuum generator 21, a fan, a pump device or the like, on its suction side. The separation device 10B comprises an input opening 14', into which a conveying pipe 100B of the material conveying system is operatively connectable, for example via an input branch 14B. According to an embodiment, the separation device 10B may comprise switching means for operatively connecting the material conveying pipe to the input opening of the separation device. According to an embodiment, the switching means may also comprise the input branch 14B and a connecting means 15B, through which the material conveying pipe 100B is operatively connectable, for example via an input branch, to the input opening 14' of the separation device.

[0020] According to an embodiment, such as the embodiment of FIG. 1, the collection vessel 11B of the separation device 10B is a so-called cyclone separator with a chamber space bounded by side walls 11′, 11″, whose base can be, for example, a bottom hatch 7, and an upper end wall 34. The separation device can also be another type of separation device. For example, FIG. 10 and FIG. 10a present another type of separation device. The chamber space of the collection vessel 11B of the separation device 10B can be wider at its top, for example mainly cylindrical, and the chamber space can narrow at the bottom, for example cone-like, as it progresses towards the base. The separation device can have a material discharge opening 6 and a hatch 7 for opening and closing said opening. The material discharge opening 6 can also be arranged elsewhere, for example in the wall of the separation device. In the embodiment of FIG. 1, the material discharge opening 6 is arranged at the bottom of the separation device, for example at its base. The input opening 14' may be connected to the wall of the collection vessel 11B of the separation device, to its top 11', through which the material to be conveyed, such as waste material W B is fed into the chamber space of the collection vessel of the separating device together with the conveying air a. The input opening 14' can be arranged in the wall of the chamber space of the collection vessel of the separating device, for example in the top 11' of the side wall thereof.

[0021] The input opening 14' of the collection vessel 11B may be arranged, as in the embodiment of Figure 1, for example in a wall of the separation device, at the top 11' of said wall, in the region between the end wall 34 of the discharge channel penetrating into the inner part of the separation device and the bottom of the wall 13. Thus, in the separation device 10B, the collection vessel 11B may comprise a ring-shaped section in the aforementioned region, in which the wall 13 of the discharge channel forms the inner rim of the ring-shaped section and the wall 11' of the collection vessel, typically the top of the wall, forms the outer rim of the ring-shaped section.

[0022] The conveying air a leaves the separation device through the conveying air discharge opening 16'. The conveying air is typically deflected in the separation device, in which case heavier materials entrained in the conveying air separate more easily from the conveying air.

[0023] The input branch portion 14B and the input opening 14' are, for example, as in the embodiment shown in the figure, for conveying the conveying air a and the solid particles W B The walls 11' of the collection vessel 11B may be configured such that the material (i.e., the material) is fed to the top of the collection vessel 11B while moving primarily tangentially within the vessel. Centrifugal force and gravity keep the heavier particles close to the side walls of the collection vessel of the separation device in a rotational motion, where the material falls to the base of the collection vessel.

[0024] The separation device 10B may be, according to one embodiment, a so-called deep collection vessel, which in one embodiment includes an outer vessel 12B and a collection vessel 11B. The outer vessel 12B may be, for example, a shaft or vessel arranged in the ground or soil, said shaft or vessel having a base 5 and a side wall 4. The outer vessel 12B extends some distance downwards from a surface level s. In the embodiment of FIG. 1, a separation collection vessel 11B is arranged for the outer vessel, which fits into the outer vessel 12B. In the embodiment shown, the top of the collection vessel 11B extends to a level above the surface level s.

[0025] In one embodiment, the wall 13 of the discharge channel may be arranged in the top of the collection container 11B of the separation device, which wall penetrates into the chamber space of the separation device. The wall 13 may be tubular, for example cylindrical as in the embodiment shown. The wall 13 may be on the same axis (coaxial) as the longitudinal axis of the collection container 11B of the separation device. An outlet channel is formed inside the rim of the wall 13, into which an opening at the bottom of the wall 13 enters and which opening can open into the container space. From the top of the outlet channel there is a connection via an outlet opening 16' to an outlet branch 16B for conveying air.

[0026] Thus, in the embodiment shown, the lower end of the tubular wall 13 is open. The upper end of the tubular wall 13 is closed. The wall 13 extends from its top to, and possibly even outside, the end wall 34. The discharge branch 16B is arranged in the collection vessel 11B of the separation device in such a way that, in the embodiment of Figures 1 and 2, the conveying air is exhausted from the top of the collection vessel 11B in a mainly tangential motion.

[0027] In the discharge channel bounded by the wall 13, the outgoing conveying air a (possibly material particles w B ) which causes a tangential movement relative to the conveying air (and the particles transported therewith) in the collection vessel 11B of the separation device (W B +a) is preferably in the opposite direction. The tangential (rotational) movement provided for the conveying air to be discharged is preferably in the opposite direction to the tangential movement of the conveying air (and the particles transported therewith) arriving in the chamber space (W B The movement of the conveying air through the separation device is roughly illustrated by arrows, e.g., in the figure, arrow a+(w B ) in the conveying air and the particles (w B ) from the separation device, and W B +a presents the movement of the conveying air and the material particles intended to be separated entering the separation device at least near the input opening.

[0028] Thus, the tangential movement of the outgoing conveying air may be in the opposite direction with respect to the rotational direction of the tangential movement of the conveying air entering the separating device from the input branch 14 through the input opening 14'. In this case, the rotational movement of the conveying air entering from the chamber space of the separating device 10B is countered in or near the discharge channel 13 and the speed of the conveying air is reduced. This procedure attempts to fairly well prevent harmful particles such as paper and plastic from easily rising together with the conveying air from the chamber space of the separating device 10B into the discharge channel 13 of the separating device.

[0029] Since some material particles may still remain in the conveying air, to solve this problem a separation device assembly is applied, in which an arrangement is utilized in which a second separation device that may be primarily intended as a standby separation device for the first separation device for the second material fraction. In Figure 2 and the following figures, the numbering is also used in which the letter A after the reference number indicates a component of the first separation device 10A and the letter B after the reference number indicates a component of the second separation device 10B.

[0030] Figure 2 presents an embodiment in which two separation devices, a first separation device 10A and a second separation device 10B, are presented in the direction of arrow A in Figure 1. The markings presented above in Figure 1 to which the (second) separation device 10B and its components are referred to can also be used in conjunction with the first separation device 10A, in which case the letter B in the reference numerals is replaced by the letter A.

[0031] FIG. 2 presents an embodiment in which two separation devices 10A, 10B are arranged to be operatively connected to a material conveying pipe 100. A valve means 109 is arranged in the material conveying pipe, by means of which the input of the material can be directed either into the first separation device 10A or into the second separation device 10B. From the valve means 109, at the side of the separation device, there are two pipe branches 100A, 100B, of which the first branch can be operatively connected to the input branch 14A of the collection vessel 11A of the first separation device 10A. The second branch 100B can be operatively connected to the input branch 14B of the collection vessel 11B of the second separation device 10B. The embodiment of FIG. 2 can be used, for example, to separate two different fractions W in the material to be conveyed. A , W B In this case, a part of the material (first material W) conveyed from the input point 1 (FIGS. 8 and 9) may be applied in a situation where A ) is poured into the collection vessel 11A of the first separation device 10A, and a second portion of the material coming from the input point (second material W B ) flows into the collection vessel 11B of the second separation device 10B. According to a second embodiment, the separation devices 10A, 10B of Fig. 2 may be used to increase the capacity, in which case the interval between emptying the vessels may be extended. In this case, when the first vessel 11A of the separation device 10A is full, the material coming from the conveying pipe 100 may be guided by the valve means 109 into the vessel 11B of the second separation device 10B.

[0032] The first separation device 10A and / or the second separation device 10B can be releasably connected in relation to the material conveying tube 100, 100A, 100B and / or the channel 25 leading to the suction side of the partial vacuum source. The connection means 15A, 15B can also be arranged between the conveying tube 100A, 100B and the input channel 14A, 14B. The connection means 15A, 15B and the input channel 14A, 14B together can form, for example, a snap-fit ​​connection. The connection means 15A, 15B can be, for example, a sleeve that is movable between two positions, i.e. a first position in which there is a connection between the conveying tube 100A, 100B and the input channel 14A, 14B and a second position in which the input channel 14A, 14B is releasable from the connection. A second connection means can also be arranged in relation to the channel 25 leading to the suction side of the partial vacuum source and the discharge channel 16A, 16B of the separation device. The connecting means 17A, 17B and the exhaust channels 14A, 14B together form, for example, a snap-fit ​​connection. The connecting means may, for example, be a sleeve that is movable between two positions, namely a first position in which there is a connection between the channel 25 leading to the suction side of the partial vacuum generator and the exhaust channels 16A, 16B, and a second position in which the exhaust channels 16A, 16B are detachable from the connection. The connecting means may, for example, be used with the actuators 15A', 15B', 17A', 17B'.

[0033] According to one embodiment, the outer container 12A, 12B of the separation device 10A, 10B is buried below the surface S of the ground or a corresponding one. All levels at which material can be dropped into the container and, correspondingly, at which emptying of the container can be carried out can be considered as corresponding surfaces. The walls of the outer container 12A, 12B are vertical and are formed from a cylindrical container of steel or other material, such as reinforced plastic, which is closed at the bottom and open at the top. The container is preferably submerged in the ground, in a cavity made for that purpose, such that most of the volume of the container is located below the surface S of the ground. In the embodiment of FIG. 1, the side wall 4 of the outer container continues above the surface S of the ground. In the embodiment of the figure, the cross-sectional area of ​​the outer container on a horizontal plane is constant, but it becomes gradually wider on the horizontal plane going upwards, in which case the outer container slightly expands upwards in a conical manner.

[0034] 8 and 9 present a part of a pneumatic material conveying system, which comprises a material conveying pipe 100, on the side of which at least one, typically multiple, input points 1 are arranged. The input point 1 is a feed station for the material intended to be conveyed, more specifically waste, from which the material intended to be conveyed, more specifically waste, such as household waste or recyclable material, is fed into the conveying system. The input point 1 may be a garbage chute, into which the material is fed from input openings on different floors of a building. The system may comprise multiple input points 1, from which the material intended to be conveyed is fed into the conveying pipes 100, 101, 102. By opening and closing shut-off means, such as valve means 103, possibly associated with the input points, the material can be conveyed from the input point 1 into the conveying pipe 100. The input point 1 is connected on the valve side to the conveying pipe 100 or to the input pipes 101, 102 connected thereto. Typically, the conveying piping comprises a main conveying pipe 100 to which a number of branch conveying pipes 101 can be connected, and to which a number of feed stations 1 can be connected. In the embodiment of Figs. 8 and 9, the input point 1 can be a waste input point 1 arranged on the surface of the ground, which input point is one or more input openings 31, which can typically be opened and closed by hatches. The input point 1 can be connected via a feeder channel 105 to a material shaper 104, which shapes and compacts the material to the conveying piping 100, 101, 102, which has a smaller diameter than the feeder channel. The solution according to the invention is also suitable for material conveying systems of the type in which no material shaper is used, but instead the material is conveyed from the input point directly into the conveying piping. The conveying piping can be arranged to run underground. In the embodiment of Figs. 8 and 9, the conveying piping can comprise at least one replacement air duct 110 in which a replacement air valve 108 is arranged. Arrangements for regulated introduction of replacement air into the conveying piping (eg valve means 30) may be at or near the point of injection 1.

[0035] The material transport pipe 100 of the transport piping is interchangeably connectable to either the material transport pipe 100A leading to the first separation device 10A or to the material transport pipe 100B leading to the second separation device 10B.

[0036] In a method according to an embodiment, the material and the conveying air are treated in a pneumatic material conveying system. The conveying system comprises at least one input point 1 for the material, into which the material to be conveyed is fed through an input opening 31 and conveyed together with the conveying air in a material conveying pipe 100 that is connectable to the input point 1. The conveying system has at least two separation devices 10A, 10B, which separate the material to be conveyed from the conveying air. The conveying system further comprises means for creating a pressure difference and / or a conveying air flow in the conveying pipe 100 at least during the conveying of the material. These means include at least one partial vacuum source 21 and means for regulated feeding of replacement air into the conveying pipe. In this method, the material can be conveyed into any of the at least two separation devices 10A, 10B by the transport air flow in a selected manner. In this method, at least one of the aforementioned separation devices 10A, 10B is configured to act as a standby separation device for the second separation device. In this case, any material that may have been traveling in the conveying air through the first separating device is forced together with the conveying air from the discharge opening 16' of the first separating device into the material input opening of the second separating device (standby separating device) and separated from the conveying air in the second separating device.

[0037] According to one embodiment, the first separation device 10A and the second separation device 10B are configured to be operably connected in an interchangeable manner such that the second separation device 10B can function as a standby separation device for the first separation device 10A and / or the first separation device 10A can function as a standby separation device for the second separation device 10B.

[0038] In one embodiment, the first separation device 10A and the second separation device 10B may be configured to be operatively connected (successively) in such a way that the second separation device 10B can act as a standby separation device for the first separation device 10A, in which case the input channel 14A of the first separation device is operatively connected to the material conveying pipe 100, and the discharge channel 16A for conveying air of the first separation device 10A can be operatively connected to the input channel 14B of the second separation device 10B via the material path 16A14B. The discharge channel 16B for conveying air of the second separation device 10B can be operatively connected to the channel 25 leading to the suction side of the partial vacuum source 21 of the pneumatic material conveying system. Such an embodiment or operating state is presented, for example, in Figures 3, 6, 8, 9 and 10.

[0040] According to one embodiment, the first separation device 10A and the second separation device 10B can be arranged such that the second separation device 10B acts as a standby separation device for the first separation device 10A, in which case the input channel 14A of the first separation device 10A is operatively connected to the material conveying pipe 100, the outlet channel 16A for conveying air of the first separation device 10A can be operatively connected to the input channel 14B of the second separation device 10B, and the outlet channel 16B for conveying air of the second separation device 10B can be operatively connected to a channel 25 leading to the suction side of a partial vacuum source 21 of the pneumatic material conveying system, or or The first separation device 10A can function as a standby separation device for the second separation device 10B, in which case the input channel 14B of the second separation device 10B is operatively connected to the material conveying pipe 100, the discharge channel 16B for conveying air of the second separation device 10B is operatively connected to the input channel 14A of the first separation device 10A, and the discharge channel 16A for conveying air of the first separation device 10A can be operatively connected to the channel 25 leading to the suction side of the partial vacuum source 21 of the pneumatic material conveying system, which may be configured to be operatively connected in succession in an exchangeable manner. This embodiment and operating state can be realized, for example, by the separation device assembly presented, for example, in Figures 3 to 5, 8 and 10.

[0041] In one embodiment, material paths 100A, 100B are arranged between the material conveying pipe 100 and the input channel 14A of the first separation device and between the material conveying pipe and the input channel 14B of the second separation device 10B, which are provided with at least one valve means 109 in such a way that the path from the material conveying pipe 100 via the first material path 100A to the input channel 14A of the first separation device 10A and / or via the second material path 100B to the input channel 14B of the second separation device 10B can be opened or closed. The valve means 109 can be, for example, a diverter valve. By means of the at least one valve means 109, the input of material can be diverted from the conveying pipe 100 either to the first separation device 10A or to the second separation device 10B depending on the position of the at least one valve means.

[0043] According to an embodiment, the valve means 111A is arranged in the path 16A14B from the discharge channel 16A for conveying air of the first separation device 10A to the input channel 14B of the second separation device 10B. Such an embodiment or operating state is presented, for example, in Figs. 3 to 10. When the valve 111A is open, the transport air flow can pass from the discharge channel 16A for conveying air of the first separation device 10A into the input channel 14B of the second separation device when the suction side of the partial vacuum source 21 is connected to work in the discharge channel 16B for conveying air of the second separation device 10B and the connection from the material conveying tube 100 to the input channel 14A of the first separation device is open. In this case, for example, the first material W A can be transported from the input point into the first separation device 10A via a transport pipe, when the second separation device 10B acts as a standby separation device for the first separation device. Such operating states are presented, for example, in Figs. 3, 4, 8 and 10.

In such a case, a simplified separation device assembly may be used, in which there is no path from the discharge channel 16B of the second separation device to the input opening of the first channel, but instead there is a path from the discharge channel of the second separation device into the channel 25 leading to the suction side of the partial vacuum source 21.

[0044] According to an embodiment, the valve means 111B is arranged in the path 16B14A from the discharge channel 16B for conveying air of the second separation device 10B to the input channel 14A of the first separation device 10A.

Such an operating state is presented, for example, in FIG.

[0045] According to an embodiment, the first separating device 10A and / or the second separating device 10B are, in terms of their working principle, cyclonic separating devices. Such an embodiment is presented, for example, in Figures 1 to 9. There are other types of cyclonic separating devices, and the invention is not limited to the embodiments presented merely in the figures.

[0046] According to an embodiment, the first separation device 10A and / or the second separation device 10B are separation device containers.

The input opening 14' and at least one discharge opening 16' are formed or arranged in the end wall of the separation device. There can also be more discharge openings 16' in the separation device, for example two, as in the embodiment of Fig. 10, Fig. 10a. The input opening 14' of the first separation device 10A can be connected to the input channel 14A of the second separation device, and the input opening 14' of the second separation device 10B can be connected to the input channel 14B of the second separation device. At least one discharge opening 16' of the first separation device 10A is connectable to the discharge channel 16A of the first separation device. At least one discharge opening 16' of the second separation device 10B is connectable to the discharge channel 16B of the second separation device. The means 16'' for restricting the access of material from the container space of the separation device to the discharge openings can be arranged in relation to the at least one discharge opening 16', similar to the embodiment of Fig. 10, Fig. 10a. The means 16'' for restricting the access of material from the container space of the separation device into the discharge openings 16' can be such that it allows the passage of the transport air flow but prevents the passage of at least a part of the solid material particles from the container space into the discharge openings 16'. According to an embodiment, the means for restricting the access of material from the container space of the separation device to the discharge openings 16' is, for example, a wall, a grill or a net in which an opening is formed. According to an embodiment, the means 16'' for restricting the access of material from the container space of the separation device into the discharge openings 16' is, for example, tubular or forms a channel, for example together with the wall of the separation device. In the embodiment of FIG. 10a, the discharge opening 16' may be arranged at the top of the container of the separation device 10A, 10B, for example near the corner between the top wall and the side wall.According to one embodiment, the input opening 14' is arranged at the top of the container of the separation device, for example in an end wall. The input opening can be arranged, for example, in the same wall as the discharge opening 16', as in Fig. 10, 10a. In the embodiment according to Fig. 10, 10a, the material fed into the separation device passes from the input opening 14' to the base of the container space of the separation device, and the conveying air leaves from the discharge opening 16'. In this case, the material W fed into the first separation device. A The conveying air a and any material particles (w) that may have remained in the transport air stream are separated from the conveying air and remain in the first separation device 10A. A ) is fed via at least one discharge opening 16' and discharge channel 16A of the first separation device 10A, via material path 16A14B and input channel 14B of the second separation device 10B to the input opening 14'. In the second separation device 10B (in the standby separator), the material w possibly remaining in the transport air stream is fed to the input opening 14'. A is separated again from the conveying air a exiting the second separating device 10B via at least one discharge opening 16'. Correspondingly, the material may be conveyed from the conveying pipe to the second separating device 10B, in which case the first separating device may function as a standby separating device, as presented above with respect to the separating device assembly according to FIG.

[0047] The separation devices 10A, 10B may be, for example, exchangeable containers. The filled separation devices 10A, 10B are removed for emptying, for example by means of a transport means. The empty separation devices are replaced with full separation devices.

[0048] According to one embodiment, the downstream separating device in the direction of travel of the conveying air, i.e. the standby separating device, receives the material particles travelling with the conveying air through the upstream separating device in the direction of travel of the conveying air and separates these particles from the conveying air. Thus, in this case, the exhaust air of the upstream separating device, i.e. the conveying air (and possibly the material particles), is fed through a second separating device, i.e. the standby separating device.

A 6, 7 and 9 present embodiments adapted to be always used as a standby separating device for a second separating device 10B (type 10B). In these embodiments of figures 6, 7 and 9, the standby separating apparatus is not adapted to be used for the second separating device 10B, but instead in those devices the exhaust air is sent from the discharge opening 16' to a path 25 leading to the discharge branch 16B of the second separating device and to the suction side of the partial vacuum generator 21. The exhaust air can be sent via the partial vacuum generator, possibly via a sound diffuser and / or a filter 23, for example to an outward blowing tube 24 or circulated back into the material conveying tube.

A When the type of waste is, for example, mixed waste or paper or plastic, the second type of material W B The second separation device 10B is used as a standby separation device. The second type of material may be a different type of material than the first type of material, such as biological waste, mixed waste, or possibly the same type of material.

According to one embodiment, the collection vessels 11A, 11B of the separation devices 10A, 10B function as cyclone separators. According to one embodiment, the collection vessels 11A, 11B of the separation devices 10A, 10B are lifted by lifting means 50, 51, 52 during the emptying phase.

[0054] According to one embodiment, material may also be fed directly into collection vessels 11A, 11B of separation devices 10A, 10B from an input opening 9 arranged at the top of the vessel. The feed opening is typically an opening that opens and closes, and a hatch 19 is arranged to close it. The hatch 19 may, for example, be hinged to the top of the separation device, for example to an upper end wall 34 or lid.

[0055] According to one embodiment, in this method, materials are fed into the conveying tube 100 from an input point 1 for the materials, which is an input point for waste or recyclable materials, such as a waste receptacle or trash chute.

Depending on the position of the valve means, the passage of the material from the conveying pipe can be selected either into the first separation device 10A or into the second separation device 10B. The valve 109 is, for example, a diverter valve. The valve 109 can, for example, be a three-way valve. Instead of or in addition to the valve means 109, for example a three-way valve, separate valve means may also be arranged in the first channel 100A and / or the second channel 100B.

[0063] According to one embodiment, the valve means 111A may be arranged in the material path 16A14B arranged between the discharge channel 16A leading from the discharge opening 16' for the conveying air of the first separation device 10A and the input channel 14B leading to the input opening 14' of the second separation device 10B.

[0066] According to one embodiment, the partial vacuum source 21 may be arranged in relation to the separating device and in its vicinity. According to another embodiment, the partial vacuum source 21 is arranged in a space arranged at a certain distance from the separating device, for example in a building. In this case, the separating device may be arranged outdoors and the partial vacuum generator may be arranged indoors. The exhaust air of the outward blowing tube may be arranged, for example, in the vertical flue of the building. The top end of the outward blowing tube 24 may be placed, for example, on the roof of the building.

[0067] According to yet another embodiment, the partial vacuum generator 21 can be a mobile device or a mobile means, for example a mobile device arranged in a vehicle. The mobile means can be, for example, a small lorry or a van, or the partial vacuum source 21 can be arranged in a trailer, which can be towed by a vehicle. The partial vacuum source 21 can comprise a pump unit in which a partial vacuum generator, such as a vacuum pump, is integrated and a drive device 22 for driving it. The suction side of the partial vacuum generator is connected in a first operating state via a media path to the collection vessel of the first and / or second separation device. In this case, the suction / pressure difference required for the conveying of the material can be provided in the collection vessel 11A, 11B and the conveying pipe 100, 100A, 100B.

[0068] In the embodiments of FIGS. 3, 4, 5, 6 and 7, the material W, such as waste, is separated from the conveying air. A , W B The separated material W drifts to the bottom of the collection vessel 11A, 11B of each separation device 10A, 10B under the influence of gravity. In the figure, the drift of the separated material to the bottom of the collection vessel 11A, 11B of each separation device 10A, 10B is indicated by arrows. A , W B are depicted as simplified bowls in the figures. The separated material is removed, for example, as required, from each collection vessel via a material discharge opening 6 arranged, for example, in the bottom of the collection vessel 11A, 11B of each separation device 10A, 10B, for example, by opening a hatch 7 and closing the discharge opening 6.

[0069] For the material removal phase, the collection receptacles 11A, 11B may be lifted from the outer receptacle 12A, 12B by lifting means 50, 51, 52 (hoisting devices themselves not shown) and placed in a receptacle of a transport means, e.g. a garbage truck, e.g. via a material discharge opening 6 arranged at the bottom of the collection receptacle 11A, 11B, e.g. by opening the hatch 7 and closing the discharge opening 6. Figure 11 shows the lifting of the collection receptacle from the outer receptacle.

[0070] Conveying air a is fed from each separation device 10A, 10B having an outlet branch 16A, 16B for the conveying air. The conveying air is typically deflected within the separation device, in which case heavier materials entrained in the conveying air are more easily separated from the conveying air.

[0071] A partial vacuum is created in the conveying pipe 100 when the suction side of the partial vacuum generator 21 is connected directly or via a conveying air duct to the container 11A, 11B of the first or second separation device, to which the delivery end of the conveying pipe 100 is operatively connected. In this case, the suction works in the conveying pipe 100 via a medium path that connects to the container of the separation device. A feed valve 103 may be between the main conveying pipe 100 and the branch conveying pipe 101 and the input point 1, which valve is open in this operating state. In this case, the suction can also work in the feeder channel 105 of the input point 1 and in the possible shaper device 104. In this case, the material batch intended to be conveyed is conveyed in the input pipe, into the branch conveying pipe 101 and then into the main conveying pipe 100. Possible exchange air enters the conveying pipe, for example via the input point 1, for example when opening the valve 103 or the valve 30. When the input point valves 103 , 30 are closed, the valve 108 of the exchange air duct 110 can be opened to admit exchange air into the conveying pipe 100 .

[0072] The waste material is transported along a transport pipe 101, 100, 100A or 100B to a vessel 11A or 11B of a separation device, where the transport air a separates from the material, which remains in the collection vessel 11A or 11B.
