Description

BACKGROUND OF THE INVENTION The present invention relates to an apparatus according to the preamble of claim 1.

The invention also relates to a waste container according to claim 11.

The invention relates generally to material transfer systems, such as vacuum transport systems, in particular to waste collection and transfer, such as the transfer of household waste.

Systems are known for transferring waste through pipeline differential pressure or suction. In these, waste is transported over long distances in the pipeline by suction. Typically, a vacuum system is used to provide a differential pressure, whereby the vacuum in the transfer tube is provided by vacuum generators, such as vacuum pumps or ejector devices. The transfer tube typically has at least one valve member that opens and closes to regulate the replacement air entering the transfer tube. The systems utilize feed points, such as waste chutes, at the feed end of the material into which the material, such as the waste material, is fed, and from which the material to be transferred is transferred to the transfer tube by opening a drain valve member. The waste is transferred mainly by the pressure difference caused by the air flow. Air flow is usually achieved by suctioning air through the piping. Waste material, such as bagged waste material, is transferred from the feed point to the transfer tube and further to a separation device where the waste is separated from the transport air. The separator device may have a transfer device, such as a transfer member arranged in a cylinder-piston assembly, for transferring waste from the separator device to a waste container, for example a transport container.

C/O

The transfer device is thus mainly a press which, on the other hand, transfers the material to the transport container and also compresses the material to a more compact size, thus accommodating more than 30 exchangeable waste containers.

The apparatus according to the invention is further characterized by what is mentioned in the claims 2-10.

The waste container according to the invention is characterized by what is mentioned in claim 11.

The solution of the invention has a number of significant advantages. The solution of the invention provides a highly efficient and reliable solution for reliably disassembling and securing the waste container in connection with pneumatic waste transfer systems, particularly for applications where waste is transferred from the separator to a separate, removable waste container. By providing a switch-20 field device comprising a screw member and a waste container, a reliable and reliable solution is provided.

Fig. 1 shows a solution in which a pneumatic waste treatment system separator 1 is provided with a press / compactor apparatus 9 having a 3535 transfer member 10 and its actuator 11. The separator 1 comprises a reservoir part 4 connected to an inlet pipe 2 which is connected to a waste transfer pipeline ( not shown) and that can be connected to feed points (not shown). Material such as household waste is fed at 4 feed points to the pipeline where it is transferred by suction / pressure differential and / or transport air flowing through the pipeline to the separator reservoir portion 4 from the inlet pipe 2 where the separator reservoir portion 4 separates waste material from the transport air, e.g. the material extends to the lower part 5 of the separating device 5. An outlet pipe 3 is connected to the upper part of the separating device, which is connected to the suction side of a vacuum generator such as an ejector pump or a fan. The conveying air is discharged from the separating device reservoir part 4 to the outlet pipe 3.

In the embodiment of the figure, the container part 4 of the separating device 1 comprises a tapered portion towards the lower part. In the embodiment of Figure 1, after the conical portion, a cylindrical portion is provided in the lower part 5 of the separator container 4, with a material outlet 6 at its lower part. Material can thus be discharged from the container part 4 through an outlet 6 formed therein.

Provided with the separating device 1 is a clamping device 9 for the material outlet 6 of the separating device 4 and a separate waste container 15, the inlet 8 of which is aligned with the outlet 6 of the separating device 4. The outlet 12 of the press device 9 can be aligned with the inlet 14 of the separate waste container 15. The inlet 8 of the press device is connected to the lower part 5 of the part 4 of the separator device 20 by the collar part 7.

The clamping device 9 has a transfer member 10 for moving between at least two positions. The transfer means is arranged to transfer waste material from the inlet 8 to the press device towards its outlet 12 and further to a separate waste container 15 from the inlet 14 or at least in the vicinity of the inlet 14. At the same time, the shipment can also compress the shipped waste more compactly, i.e. compacting the £ 2 waste into a separate waste container 15.

Fig. 2 shows a press device 9 and a separate waste container 15, such as a waste container, which can be connected to it. The figure shows the x inlet 8 on the press device 9 and the collar 7 surrounding the inlet. The press device 9 and the waste container 15 are arranged in the figure on a mounting surface 25, such as a floor surface. Clamping device 9

The CM-33 5 road tank 15 and the press device 9 are aligned so that the outlet of the press device and the inlet of the waste container are aligned. The apparatus according to the invention is provided with coupling means 16, 17 by means of which the removable waste container 15 can be attached to and disconnected from the pneumatic waste transfer system, in particular its press 9. The coupling means 16, 17 comprise a coupling device 16 and its counter member 17. In the embodiment of Fig. 2, two coupling means 16, 17 are provided, one of which is shown in the figure and the other is at a corresponding position on one side of the clamping device.

Fig. 3 shows in more detail and partly in section the coupling means 16, 17 according to the invention. In the embodiment of Fig. 3, the coupling device 16 comprises a screw member 18, actuated by an actuator 19. The coupling device 16 comprises a body 20 arranged in a frame structure 24 supported on the mounting surface 25 in the figures. The frame structure 24 15 may be part of the frame structure of the press device 9 or a separate frame structure. The counter part 17 of the coupling means 16, 17 is arranged in the embodiment of the figure on the structures of the waste container 15, preferably on the body of the waste container 1 5. The counterpart comprises threaded members which are counter-threads to the threads of the coupling screw member 18. In the figure, the counter part 17 is arranged in a counter piece 30 having a hole formed therein, such as a bore, in the wall of which the counter threads are arranged.

Figure 4 shows the switching apparatus according to the invention in a first position, i.e. in a position where the waste container 15 is separate from the connection to the pneumatic waste system 25, in particular to its clamping device 9. In the embodiment of Figure 4 by means of which the waste container 15 is moved at least in the vicinity of the press device ° and / or moved at a distance from the press device 9. The actuation means 26, 27 comprise an actuator 27, such as a hydraulic cylinder, and In Fig. 4, the handle portion 26 of the actuator is connected to the lower portion of the waste container 15, from which the actuator 26, 27 moves the waste container 15 toward the press device 9.

The part may be provided with friction reducing means to facilitate movement of the waste container, for example, as shown, roll members 28.

The outlet of the press device comprises a collar 13 which, when connecting the waste container to the press device, fits in with the inlet of the waste container, preferably

O -DC

CM-33 6 such that the collar 13 of the outlet of the press device extends inwardly from the inlet of the waste container 15. The inlet for the waste container may also comprise a collar 14.

Figure 4 further shows an arrangement of the counter part 17 in the waste container 15. A space 33 is formed in the waste container 5 in which the counter body 30 is arranged. The counterpart is formed with a bore 31 and counter threads 32 which fit the threads of the screw member of the coupling device 16. The counterpart is preferably arranged in the vicinity of the support beam 37 of the waste container 15. The support beam 37 is provided with a bore 34 which extends into the space 33 provided in the waste container for the counter piece 30. There is a support surface 10 for the counter body 10, on which the counter body is supported at least when the connection of the waste container is formed with the connection means 16, 17 or when the connection is removed.

Fig. 5 shows another position in which the actuator 26, 27 has moved the waste container 15 in connection with the pneumatic waste pipe conveying system, in particular its clamping device 15, with the screw member 18 of the coupling device 16 at its counterpart 17 and its orifice 31. The coupling device has a resilient property which will be described in more detail later with reference to Figures 7-10.

The actuator 19 of the coupling device 16 utilizes a screw member 18, whereby the threads of its screw member correspond to the counter threads of the counter part 17, whereby the screw member 18 and / or its counterpart 17 move relative to one another

Fig. 6 shows a third position in which the waste container 15 is connected to a pneumatic waste pipe transport system, in particular to a press device 9. The coupling means 16, 17 provide a secure and reliable connection between the clamping device 9 and the waste container 15.

30 Figs. 7 to 10 show the coupling means, for the sake of clarity, still removed from their installation sites and simplified. In Fig. 7, the coupling device 16 comprises a body part 20, which is provided with an inner body 40 on which the actuator 19

o is secured again. The body portion 20 is a tubular portion of substantially rectangular cross-section with rounded corners.

The parts and operation of the coupling device 16 are better illustrated in Figures 8 to 10, which is a longitudinal cross-section of the coupling device 16 and its counterpart 17.

O -DC

The CM-33 7 has an inner body 40 on the inside of the field unit body 20, at which end the actuator 19 is attached. A screw member 18 is attached to the drive shaft 41 of the actuator by a coupling member 42. The screw member 18 extends through the body portion 20. Within the tubular body portion 20 is a transverse wall portion 43 which divides the interior space of the body portion 20 into at least two compartments 51, 52. In the first compartment 51, the inner body portion 40 can be moved longitudinally along the transverse wall 43 of the body portion 20. The transverse wall 43 has an opening through which the screw member 18 or its drive means extends in embodiments of the figures. The body portion second compartment 52 extends to the right of the transverse wall 43 in Fig. 8, toward the second open end 10 of the body member. The second body compartment 52 is provided with a spring member 44. The spring member 44 is arranged in a space limited by the transverse wall 43 and the sleeve member 45 in the second compartment. The screw member 18 extends through the spring member and the sleeve member 45. The screw member 18 is provided with clamping means 46, 47 for holding the sleeve member 45 at a particular position relative to the screw member 18. The spring force 44 of the spring member 44 then presses the sleeve portion 45 towards the first clamping means 46.

The screw member 18 and the sleeve portion 45 thereon are arranged to move in the second body section 52 toward the transverse wall 43. Accordingly, the inner body 40 moves in the first section 51 away from the transverse wall 43. This arrangement, i.e., the flexible arrangement, provides a screw the counter member 17 is brought against the free end 50 of the screw member 18. The free end 50 of the screw member has a tapered, frustoconical region 49 at its head. The counter member 17 has a correspondingly tapering portion which is guided toward the bore and counter threads of the counter member.

In the elastic arrangement, the spring force tends to press the screw member towards the counter member, thereby facilitating the engagement of the screw member and the counter member at the beginning of engagement.

g 30 x In Fig. 8 the coupling device is shown in the first position. The waste container and its counterpart 17 are spaced from the screw member 18. In this case, the coupling device 16

CD

o the spring 44 pushes the screw member 18 to the right in the figure, but the inner body 40 is in contact with the transverse wall 43. The screw member is thus in its first extreme position ^ 35, i.e., in the right in Figure 8.

8

In Figure 9, the waste container and its counter member 17 are brought towards the screw member, whereby the screw member is moved against the spring force of the spring 44 in Figure 9. The transverse wall face of the sleeve member is in contact with the transverse wall and the spring is in a compressed state. Thus, in the figure, the screw member 18 is in its second extreme position, 5 in figure 9, to the left. At the same time, the inner body and the drive of the screw member have also moved to the left with the screw member in the first compartment. The end of the screw member contacts the bore 31 of the bore 31 of the counter member 17.

Fig. 10 shows a position in which the screw member 18 of the coupling device 16 is rotated by the actuator 10, thereby forming a connection between the screw member 18 and the waste container counter member 17. When the screw member 18 is rotated by the actuator 19 and preferably the spring force of the spring 44 acts, at least initially by pressing against the screw member, the screw member threads readily align with the counter threads 32 of the counter member 17. the inner body 40 or other stop member comes into contact with the transverse wall 43. The screw member then pulls the counter member and the waste container towards the press device so that a reliable connection is established between the pneumatic waste pipe transport system and the waste container 15.
