ROTARY PROCESSING BODY BLADE, PROCESSING BODY AND ROTARY PROCESSOR

Field of the Invention 5

The invention relates to a replaceable blade piece for a rotary shear processing member according to the preamble of claim 1.

The invention also relates to a rotation-shaping processing element according to the preamble of claim 7.

The subject of the invention is also a rotary shear according to the preamble of claim 13.

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

BACKGROUND OF THE INVENTION Systems are known in which waste is conveyed in a pipeline by a differential pressure or suction air. In these, waste is transported over long distances in the pipeline. Typically, a vacuum device is used to provide a differential pressure, in which 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 vent-25 brick member which opens and closes to regulate the replacement air entering the transfer tube. The systems use feed points at the material inlet end from which material such as waste is transferred to the system. The system may also comprise waste manholes into which material, such as waste material, is fed and from which the material to be transferred is transferred to the transfer tube by opening the drain valve member, by suction action through vacuum acting on the transfer tube i30 and ambient atmospheric pressure acting such as bagged waste material, from the waste shaft to the transfer tube. These pneumatic S waste transfer systems can be utilized particularly well in densely populated urban areas. Such areas include tall buildings where waste feeds to the pneumatic waste transfer system are performed through a waste shaft or other feed point provided in the building.

2 In a closed system, the waste is transported to a receiving station where the waste is compressed by a press only after transport. The pipes of the pneumatic transmission system are usually quite large in diameter, for example about 500 mm in diameter.

W08203200 A1 discloses a device for comminuting, compressing and ejecting bulky bulk material, particularly household waste, by means of which the waste material passed through the device can be compacted. The solution according to the publication typically requires high operating efficiencies, especially in situations where the 10 devices are used to cut or grind material, whereby the energy consumption of the drives and the costs of the drives are high. In addition, the passage of stones or other similar material between the cutting blades can cause the blades to break. Further, solutions disclosed in WO2011098666, WO2011098667, WO2011098668 and WO2011098669 in which rotary shearers are applied are known. The prior art rotary shifter comprises a plurality of rotatable processing members and typically a non-rotating processing member therebetween. These have proven to be effective in their purpose. On the other hand, there is a need for further development of material handling tools for rotary shearers to improve their usability and adaptability to different applications and to enhance maintenance.

The object of the present invention is to provide a completely new solution in connection with the rotary shaping processing means, which can further improve the operation of the processing means, their applicability to various applications 25 and their maintenance.

The solution according to the invention has several significant advantages. The invention provides a highly efficient solution for material handling in a rotary molding machine. The blades and processing members of the invention can efficiently handle the material in the rotary shear and provide efficient treatment and feed of the material 15 through the rotary shear. The solution according to the invention can enhance the feeding of material through a rotary shear to such an extent that the suction / pressure difference used in the known solutions in the feeding of material can be reduced. This in turn reduces the energy requirement of the pneumatic material piping system. Further, the invention can effectively influence the handling of the material when the handling members are used in the other direction. In this case, the guide surfaces of the blade pieces can, on the one hand, promote the feeding of material and, on the other hand, relieve the load on the handling members. The solution of the invention enables the material to be treated to be centralized, i.e. centered, whereby the material can be effectively fitted in a conveying tube or container. In particular, the waste material according to the invention can be effectively compacted by the rotary shear according to the invention and efficient transport can be achieved with a noticeably smaller tube size as compared to unmodified waste material.

cv Effective operation of the apparatus is achieved by certain angles between the guide surfaces and / or the edges o of the cutting pieces of successive processing members.

By arranging a blade, preferably a replaceable blade, in the first and second directions of rotation of the material in the rotatable manipulation member, material handling can be made more efficient and the possibility of blockages being reduced.

By using rotatable manipulation means in different directions of rotation in sequences, i.e. sequences, it is possible to ensure the efficient operation of the device and to reduce the chance of results. In addition, the interchangeable blade pieces allow the material and other features to be adapted to the requirements of each application. Further, by making the blade of the processing member interchangeable, it can be easily replaced for wear or other reasons. By forming a non-rotatable processing member of the rotary cone into a relatively thin section, a cutting distance is achieved between it and the rotatable processing member, which is very effective in treating some types of waste, for example cardboard or board 5. The solution according to the invention, in combination with the cutting pieces of certain types of processing elements and a non-rotatable, relatively thin processing member, thus provides an efficient treatment of the material.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows an embodiment in which the solution according to the invention 10 can be utilized. The figure shows, in simplified form, a rotary shaping device 1 arranged in connection with a waste shaft 3 or the like with a fitting part 2. Only a part of the waste shaft is shown. Material, such as household waste, waste paper, cardboard or other waste packed in bags, is fed to the waste shaft 3 and further through the fitting portion 2 to the inlet 6 of the rotary shifter 1. The inlet 6 is formed through. The outlet 37 is formed in the bottom plate 28 of the body of the rotary shearer 1. The material to be treated is molded and sealed in the rotary shearer and, after treatment, is discharged through the outlet 4 to the transfer pipeline 5 for example by suction and An advantage of the embodiment of the invention is that the waste material is obtained in a suitable form where it can be transported in the transport piping 4, 5. Hereby, a significantly smaller diameter transfer tube 5 may be used. According to one embodiment, for example, a tube 25 having a diameter of the order of 150 to 300 mm, preferably of the order of 200 mm, may be used. According to the invention, a simultaneous suction is used in the embodiment, whereby the material to be treated can be influenced by suction or pressure difference acting through the transfer tube 5 and the outlet connection 4 as it passes through the processing means 10A, 10B, 10C. The processing members are circumferential (or annular), each having openings 11A, 11B, 11C on the first side, the inlet side, the outlet side. At least a portion of the concept x members are adapted to be rotated in a vertical embodiment of the pattern.

co is rotated and a non-rotating, fixed processing member 10B is left between them. Under rotation converter 35, valve member 55 may be provided, such as a disc valve actuated by valve actuator 56. .

The rotary shifter comprises a body provided with processing means 10A, 10B, 510C. Below the inlet 6 of the material to be treated vertically, a plurality of handling members 10A, 10B, 10C are provided with an opening 11A, 11B, 11C leading from one side to the other. The annular processing members are arranged in a relative rotational movement about a geometric axis substantially identical to the geometry axis of the feed shaft to pass through the annular processing members by gravity and / or by suction / pressurization of the vacuum, at least modifying the bulk material by co-operating with simultaneously rotating tires and at least one solid (non-rotating) tire. The processing means 10A, 15 10B, 10C may be arranged to rotate in opposite directions, but as shown in the preferred embodiment, in the figures, one annular processing member 10B (middle processing member 10B) is fixedly attached to the body and every other annular processing member 10A processing element) rotatably. The rotation speed and direction of rotation of the rotatable processing members 10A, 20C may be varied according to one embodiment.

According to one embodiment, the rotary processing members have different rotational speeds. In one embodiment, the en-25 first processing member 10A is rotated faster and the subsequent rotation member is typically rotated at a slower min. Thus, in the figure, the lowest rotatable manipulation member 10C rotates more slowly than the first rotatable manipulation member 10A. Between them is a non-rotatable processing member 10B in the vertical direction. The mutual position of the openings 11A, 13C, 11C of the openings 11A, 10C of the rotatable manipulation members 10A, 10C changes, at least in the rotation plane, during rotation, which is advantageous for efficient material handling.

The other direction (arrow II in Figure 3) is that in which the possible blade portion 14A, 14C of the processing means is arranged to rotate forward and possibly cut material. The duration of rotation t2 of the second direction of rotation is typically shorter than the duration t1 of the first direction of rotation. According to one embodiment, the formula t2 = 0.5 * ti is preferably followed.

Thus, a portion 12A projecting toward the center of the processing member delimits the eccentric opening 11A through the ring. As the processing member 10A rotates, the blade surface 13A defines an obstruction-free passage through the processing member 11A. The inner surface 13A of the processing element, i.e. the wing surface, may be provided with elements, such as a helical groove or heel, which, as the processing element rotates in the feed direction 5, simultaneously feeds the material to be treated from the opening 11A in the processing direction. In addition, a cutting blade 14A can be provided as the direction of rotation changes. According to one embodiment, the cutter blade 14A may be a separate, replaceable part.

According to one embodiment, the angle β (beta) is 5 -45 degrees, preferably 8-30 degrees, most preferably 10-20 degrees 15. In the figure 153, below is an oblique guide surface, i.e. a lower surface 150 which is at an angle δ (delta) (FIG. 5d) with the vertical. The interaction of the oblique edge 153 and the lower surface 150 results in a downward movement of the manipulation member II on the material beneath the edge 153 and, for example, in a radial direction towards the axis of rotation, a tilted movement of the material 20. In this case, the material is also fed downwards. According to one embodiment, the angle δ (delta) is 10-80 degrees, preferably 15-60 degrees, most preferably 20-40 degrees.

The lower surface 142 of the attachment portion of the blade piece 14C is also planar in the figure, but can be shaped according to the application. The openings 144, 145, 146 extend from the upper surface 141 of the cutting insert 14C through the lower surface 142 of the blade. Between the lower surface 142 of the mounting portion and the lower surface 152 of the blade portion there is a vertical threshold portion 143 extending downward from the lower surface 142 of the mounting portion. According to one embodiment, the threshold portion 143 5 comes against the counter surface of the blade attachment point of the treatment means 10C when the blade piece is attached to the treatment means 10C, thereby supporting the attachment of the blade piece and the treatment means.

The surface 143 may be bevelled so as to guide the material downwardly in the feed direction 10 through the opening 11C when the treatment means is rotated in the first direction.

The processing member blade piece further comprises a back surface 154 which faces the surface 160 of the attachment point for the processing member 10C blade piece.

The second processing member, i.e. the fixed handling member 10B, as shown in Figs. 2b and 3B, comprises a wing portion 12B projecting into the center of the ring and having a wing surface 13B. The wing portion 12B protrudes further into the center of the processing member than the corresponding section 12A of the processing member 10A. In addition, the second processing member 13 may also be provided with a blade 14B. In the figure, the blade is an integral part of the processing element. The blade 14B may also be a separate, replaceable part. The edge of the blade 14B of the central processing member 10B or the like interchangeable blade piece is oriented in the opposite direction to the edges 153 of the rotary processing members 14A, 5C 14C, when viewed from the direction B of Fig. 2a, 14B.

Similarly, the second rotatable processing member 10C, as specifically shown in the schematic, has a wing portion 12C having a wing surface 13C. The wing portion 12C protrudes somewhat further toward the center of the processing member 10C such that, when the handling member 10C is rotated, an obstruction-free passage is defined that is smaller than the corresponding free passage opening in the handling member 10A and 10B. Further, a cut-15 blade 14C can be provided as the direction of rotation changes. In the embodiment of the figures, the blade 14C is a separate, replaceable part.

Figure 1 shows a free passage after the first and second processing means 10A, 10B and also an outlet 37 after the processing means. Figure 1 20 shows an outlet 37 after the second and third processing means 10B, 10C, which is thus a substantially free passage through the press.

The lowest rotary processing member 10C is rotatably disposed on a bottom 28 having an outlet opening 37 for discharging through the processing means 25 material extruded therewith.

In the rotary mold, the material passed through the processing means 10A, 10B, 10C is compressed and compacted.

The rotational movement, or rotational movement, of the processing members 10A, 10C may also be effected, for example, by an electric motor or other arrangement. According to another embodiment, the rotary movement is achieved by a hydraulic motor such that each of the rotatable actuating members 10A, 10C is driven by two common hydraulic motors 7. Thus, in the normal operation process, the two actuating members 10A, 10C can be rotated.

In a way, the rotary modifier functions as a reorder and compactor (ie for-10 matrix). Under the influence of the suction, the rotary shaping processing members 10A, 10C shape the material to be treated so that it fits into the outlet 37.

The direction of rotation of the processing members 10A, 10C may be varied. If too much load is generated, the operating element stops and the direction of rotation is changed. As the load becomes too large for one of the rotatable operating members, its direction of rotation is reversed.

The apertures 11A, 11B, 11C of the processing means may be of different sizes and at different positions relative to the hub to efficiently distribute the load and to provide a sufficiently large opening for the waste.

According to one embodiment, the processing means 10A, 10C can be rotated in opposite directions so that the material to be treated does not rotate with the processing means. The rotation of the material would hinder the material from being shaped to the desired shape.

It is also advantageous to rotate the manipulation members at different speeds, since then, with each rotation, the compression changes at different points and there is always a compression at some point for each waste.
