Description

Technical Field

[0001] The present invention relates to a waste material crushing and conveying device, and more particularly to a waste material crushing and conveying device that can crush and convey waste rubber materials, waste shoes and other rubber materials left after manufacturing insoles and the like, so as to realize recycling. Background Art

[0002] Generally, the function of an insole is to protect the sole of the foot, increase the friction with the ground, improve walkability, and reduce the impact applied to the sole of the foot when walking. This insole is composed of an insole, a midsole, and an outsole. The midsole is made of materials such as rubber, foamed resin or sponge with excellent cushioning power. When walking, the elastic force can be used to disperse and support the load of the human body. The outsole is attached to the bottom surface of the midsole and is made of rubber material. When walking, friction can be given. As an example, there is a method for manufacturing an insole disclosed in Korean Patent No. 10-1760577 (July 17, 2017).

[0003] On the other hand, in the shoemaking process, after a plate-shaped laminate is formed by laminating a fabric material on the upper surface of a roughly rectangular flat foam body, a sole-shaped insole laminate is cut and separated from the plate-shaped laminate. If the insole laminate is separated from the plate-shaped laminate, waste insoles with openings in the shape of soles will remain. Therefore, a large amount of waste insoles will be generated during the insole manufacturing process. Currently, the waste insoles generated are not only large in quantity, but also simply discarded, resulting in a waste of resources and environmental damage. In addition, there is a problem of malfunction of the crushing and transfer device caused by the accumulation of dust generated during the crushing process. Summary of the invention

[0026] The terms used in this specification are briefly described below to explain the present invention in detail.

[0027] The terms used in the present invention are selected from common terms widely used currently, taking into account the functions of the present invention as much as possible. However, this may be different with the intentions of ordinary technicians in the technical field to which the present invention belongs, conventions, the emergence of new technologies, etc. Therefore, the terms of the present invention should be defined based on the meanings of the terms and the full content of the present invention, rather than simple term names.

[0028] Throughout the specification, when a certain structural element is expressed as “comprising”, unless there is a special description to the contrary, it should be understood that other structural elements are also included, rather than excluded.

[0029] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. However, the present invention can be implemented in many different embodiments and is therefore not limited to the embodiments described herein.

[0030] The specific matters including the technical objectives, technical solutions and inventive effects of the present invention are presented in the following embodiments and drawings. The advantages, features and implementation methods of the present invention can be referred to in conjunction with the attached Figure 1 The embodiments described in detail will become more specific.

[0031] Hereinafter, the present invention will be described in further detail with reference to the accompanying drawings.

[0032] A waste crushing and transferring device according to a preferred embodiment of the present invention comprises: a coarse crusher 10 for crushing waste; a fine crusher 11 for crushing again the waste crushed by the coarse crusher 10; and a transfer machine 100 for storing the waste or transferring it to the coarse crusher 10 or the fine crusher 11.

[0033] First, the transfer machine 100 is provided. The transfer machine 100 sucks and stores the waste material crushed by the coarse crusher 10 or the fine crusher 11 through the pipe 34 described below, and can discharge the stored waste material as needed.

[0034] Reference Figure 1 The transfer machine 100 includes: a cavity 31, which forms a space capable of storing the waste; a pump unit 29, which is arranged on one side of the cavity 31 and is used to change the air pressure in the cavity 31; and an inlet 35, which is connected to the cavity 31, so that the waste can be transferred into the cavity 31.

[0035] More specifically, the cavity 31 is cylindrical and has a space for storing the waste. In this case, the inlet 35 is formed on the side of the cavity 31, and the inlet 35 can be connected to the coarse crusher 10 or the fine crusher 11 through the following pipe. That is, the waste crushed by the coarse crusher 10 or the fine crusher 11 can flow into the cavity 31 through the inlet 35.

[0036] Furthermore, the pump unit 29 is provided at the upper part of the cavity 31, and the pump unit 29 is connected to the inside of the cavity 31. The pump unit 29 changes the air pressure in the cavity 31 by discharging the air in the cavity 31 to the outside or supplying the outside air to the cavity 31. That is, when the waste material is transferred to the cavity 31, the inside of the cavity 31 is made to be negative pressure as a whole by the pump unit 29, or, as the high-pressure air is instantly ejected to the outside through the inside of the cavity 31, a negative pressure is formed at the upper end of the cavity 31, so that the waste material is sucked into the cavity 31 through the inlet 35 connected to the following piping.

[0037] A compressed air exhaust port may be provided at the upper portion of the cavity 31 at a position corresponding to the pump unit 29. Figure 1 As shown, the pump unit 29 is arranged at the upper left end of the cavity 31, and the compressed air exhaust port is arranged at the upper right end of the cavity 31, which can be opened or closed by a separate valve. Thus, when the waste needs to be sucked in, as the pump unit 29 ejects compressed air, the compressed air instantly passes through the interior of the cavity 31 and is ejected to the outside through the exhaust port. In other words, according to the same principle as the sprayer (Bernoulli principle), as the compressed air quickly passes through the interior of the cavity 31 and is ejected to the outside, the waste can be sucked into the cavity 31 through the inlet 35 based on the instantaneous pressure change. Furthermore, when the inlet 35 or the following piping is blocked by the waste, as the pump unit 29 quickly ejects compressed air, the compressed air can be ejected to the outside through the cavity 31, thereby realizing the transfer of the waste. As an example, the pump unit 29 may be composed of a first pump and a second pump, wherein the first pump is used to spray the air inside the cavity 31 to the outside, and the second pump is used to supply compressed air so that the compressed air is sprayed to the outside through the inside of the cavity 31 along the opposite direction of the first pump.

[0038] Next, the transfer machine 100 further includes: a discharge port 102 communicating with the cavity 31 so that the waste transferred into the cavity 31 is discharged to the outside; and an airlock 30 for opening and closing the discharge port 102 .

[0039] More specifically, the transfer machine 100 further includes a housing 104, the housing 104 is tapered, and the cross-sectional area gradually decreases from the lower side of the cavity 31 toward the bottom, and the housing 104 is combined with the lower part of the cavity 31. In this case, the discharge port 102 is formed at the lower end of the housing 104. In addition, the discharge port 102 is opened or closed by the air brake 30. As an example, the air brake 30 can open and close the discharge port 102 by the operation of a brake such as a cylinder. The air brake 30 can be a manual or automatic air volume adjustment device, which is arranged in the duct to adjust the direction, speed, and air volume of the air.

[0040] In addition, the transfer machine 100 further includes a connecting portion 105, which is formed at the lower part of the cavity 31 and is in a shape surrounding the housing 104, and has the same diameter as the cavity 31. When the waste stored in the cavity 31 is discharged downward, the connecting portion 105 is connected to a space or device for supplying the waste. As an example, the upper part of the connecting portion 105 is connected to the cavity 31, and the lower part of the connecting portion 105 is connected to the fine crusher 11. In addition, the connecting portion 105 is in the form of a cylindrical tube, and can be combined with the cavity 31 through a connecting portion 106-1. A plurality of connecting portions 105 can be provided, and they are connected to each other through a connecting portion 106-2, and their length becomes longer accordingly.

[0041] As a result, when the waste is sucked into the cavity 31, the pump unit 29 forms a negative pressure inside the cavity 31 when the discharge port 102 is in a closed state due to the airlock 30, and when the waste is discharged, the discharge port 102 is in an open state due to the airlock 30, and the waste is discharged downward through the discharge port 102. The discharged waste is transferred along the connecting portion 105.

[0042] Subsequently, the conveyor 100 further includes a filter unit 101, which is disposed inside the conveyor 100 and is used to collect dust inside the conveyor 100. As an example, the filter unit 101 is an electrostatic dust collection filter, which prevents the performance of the pump unit 29 from being reduced due to dust accumulation on the pump unit 29 or valve, etc. by electrostatically collecting fine waste particles or dust generated from the waste transferred into the cavity 31. As an example, the filter unit 101 may be provided in plurality, disposed at the lower portion of the pump unit 29, that is, may be respectively disposed at the upper left end of the cavity 31 and the upper right end of the cavity 31 corresponding thereto. Therefore, the plurality of filter units 101 may prevent dust from accumulating on the pump unit 29 and the exhaust port.

[0043] Furthermore, when the waste is discharged, when the discharge port 102 is in an open state due to the airlock 30, the pump unit 29 sprays air toward the lower part of the chamber 31 to clean the filter unit 101. In other words, when the discharge port 102 is in an open state, after the waste is discharged downward, the pump unit 29 can spray air toward the filter unit 101 to remove the waste dust and the like collected by the filter unit 101. Thus, the accumulated waste dust removed from the filter unit 101 is discharged downward through the discharge port 102 by the pump unit 29.

[0044] In addition, the transfer machine 100 further includes an exhaust port 103. When the waste is discharged, the exhaust port 103 allows at least a portion of the air ejected from the pump unit 29 to flow to the outside. The exhaust port 103 includes an exhaust filter 103-1. The exhaust filter 103-1 covers the inside of the exhaust port 103 and is used to filter the air flowing to the outside. In this case, one side of the exhaust port 103 is connected to the inside of the connecting portion 105 at one side of the connecting portion 105, and the other side of the exhaust port 103 is connected to the outside. Thus, the exhaust port 103 prevents the air pressure inside the cavity 31 and the connecting portion 105 from being reduced due to the air ejected from the pump unit 29. In this process, the waste dust in the air flowing to the outside through the exhaust port 103 is filtered by the exhaust filter 103-1.

[0045] As a result, the pump unit 29 transfers the crushed waste into the cavity 31, and when the waste stored in the cavity 31 is discharged downward, the pump unit 29 discharges the waste particles accumulated in the filter unit 101 downward by injecting air into the filter unit 101. If the filter unit 101 is cleaned in the above manner, the exhaust unit 103 needs to be provided to prevent the pressure from increasing due to the air injected by the pump unit 29 and to filter the dust in the air discharged to the outside through the exhaust unit 103 by the exhaust filter 103-1.

[0046] On the other hand, the transfer machine 100 may be used as the first transfer unit 19 , the second transfer unit 22 , the third transfer unit 25 , and the fourth transfer unit 28 .

[0047] Hereinafter, a multi-layer waste shredding and transferring device using a plurality of the transfer machines 100 will be described in detail with reference to the drawings. Figure 2 This is a perspective view showing a coarse crusher of a waste crushing and transferring device according to an embodiment of the present invention. Figures 3 to 5 The present invention is a front view, a top view and a side view of a coarse crusher of a waste crushing and transferring device according to an embodiment of the present invention. Figure 6 This is an enlarged view of a coarse crusher of a waste material crushing and transferring device according to an embodiment of the present invention.

[0048] like Figures 2 to 6 As shown, the coarse crusher 10 is a device for coarsely crushing waste materials such as rubber materials for the first time. More specifically, the coarse crusher 10 includes: a coarse crushing input part 14, which is provided with a rotating worktable 13, and a plurality of hangers 12 for hanging waste materials are formed on the worktable 13; a coarse crushing input hopper part 16, which is arranged at the front side of the coarse crushing input part 14, and is used to input the waste materials dropped from the hangers 12 into the first coarse crushing part 15; the first coarse crushing part 15 crushes the waste materials input into the coarse crushing input hopper part 16 by a first coarse crushing cutter 17, and the first coarse crushing cutter 17 is arranged at the lower side of the coarse crushing input hopper part 16 and rotates; and a first transfer part 19, which is arranged at one side of the first coarse crushing part 15, connected between the discharge hopper 18a side of the first coarse crushing part 15 and the packaging part 27a, and is used to transfer the waste particles discharged from the first coarse crushing part 15 to the packaging part 27a. Furthermore, the hangers 12 of the coarse crushing input section 14 are arranged in plurality at predetermined intervals along the edge of the work table 13, and have a length extending to the entrance of the coarse crushing input hopper section 16. The work table 13 that can be rotated by each hanger 12 can input waste materials at a position located above the entrance of the coarse crushing input hopper section 16.

[0049] The coarse crushing input part 14 is a device for screening the waste before the waste is input, and includes a circular workbench 13. The workbench 13 is in a vertical position and can be rotated by a driving part such as a motor (not shown). The workbench 13 is provided with a plurality of hangers 12 for hanging the waste on the front surface.

[0050] Among them, the above-mentioned hanger 12 is a straight rod shape, and a plurality of them are arranged at specified intervals along the edge of the workbench 13, for example, 8 hangers are arranged at intervals of about 45° along the circumferential direction of the workbench. One end of this hanger 13 is fixed on the workbench 13, and the other end extends horizontally to the upper side of the entrance of the coarse crushing hopper part 16.

[0051] Therefore, when one of the hangers 13 is located at the entrance of the coarse crushing hopper part 16 due to the rotation of the above-mentioned workbench 13, if the multiple waste materials hanging on the hanger 13 are pushed forward and taken out by automatic operation or manual operation of the operator, the waste materials will fall at the entrance of the coarse crushing hopper part 16 and can be put into it.

[0052] The coarse crushing hopper section 16 is a box-shaped structure, with an inlet for inputting waste materials formed on the rear side, and an outlet for discharging waste materials to the first coarse crushing section 15 formed on the lower side. The coarse crushing hopper section 16 is arranged on the front side of the coarse crushing section 14, so that the waste materials dropped from the hanger 12 can be supplied to the first coarse crushing section 15.

[0053] The coarse crushing feeding hopper section 16 has a structure in which the lower end portion is supported by the upper end portion of the first coarse crushing section 15, that is, the coarse crushing hopper section 16 is supported by the upper end portion of the inflowing waste in a stacked manner.

[0054] To this end, the front side of the lower end of the coarse crushing hopper section 16 is supported on the front side of the upper end of the first coarse crushing section 15 in a structure that can be rotated by a hinge device 32, and the front side of the lower end of the coarse crushing hopper section 16 is supported on the rear side of the upper end of the first coarse crushing section 15 in a structure that can be opened and closed by a hinge clamp 33.

[0055] The lower end of the coarse crushing hopper 16 is connected to the upper end of the first coarse crushing section 15 in a manner of being in close contact with each other, so that the waste transferred into the coarse crushing hopper 16 can directly enter the coarse crushing hopper 16 .

[0056] Furthermore, when the hinge clamp 31 is unlocked, the coarse crushing hopper section 16 can be tilted forward, thereby exposing the upper end of the first coarse crushing section 15 to the outside. Therefore, even if the device for maintaining, inspecting, and cleaning the inside of the first coarse crushing section 15 is not completely disassembled or disassembled, the first coarse crushing section 15 can be effectively managed.

[0057] The first coarse crushing unit 15 is a device that actually crushes the waste, is supported by a frame structure, and is provided in front of the coarse crushing input unit 14 and below the coarse crushing input hopper unit 16 .

[0058] The first crushing unit 15 includes a first crushing cutter 17 that is rotated by a driving unit 38 such as a motor driving device or a belt transmission device.

[0059] Therefore, when the above-mentioned first coarse crushing part 15 is working, if the waste is put into the first coarse crushing part 15 at the lower side from the coarse crushing input hopper part 16 on the upper side, the waste is cut into pieces by the rotating first coarse crushing cutter 17, and the crushed waste particles pass through the discharge hopper 18a located at the lower end of the first coarse crushing part 15, and are transferred to the packaging part 27a by the first transfer part 19 for packaging.

[0060] After the crushing process of the first coarse crushing unit 15 is completed, the first transfer unit 19 may transfer the waste particles to the packaging unit 27a by vacuum pressure or suction pressure.

[0061] To this end, the first transfer unit 19 is provided at one side of the first coarse crushing unit 15, and the suction side of the first transfer unit 19 is connected to the discharge hopper 18a of the first coarse crushing unit 15 via the pipe 34, and the discharge side is connected to the packaging unit 27a at the lower side, for example, connected along the up-down direction to the packaging unit 27a side formed with a bag (not shown) that can accommodate waste particles.

[0062] The first transfer unit 19 includes a pump unit 29 . In this case, the waste particles can be transferred by suction provided by the pump unit 29 .

[0063] Among them, the above-mentioned pump part 29 is supported by the upper end part of the cavity 31. In this case, the suction side of the pump part 29 can be connected to the interior of the cavity 31, and a grid is provided between the suction side and the interior of the cavity, thereby preventing waste particles from flowing into the pump side.

[0064] Furthermore, the first transfer unit 19 includes a cavity 31 for collecting a predetermined amount of waste particles transferred and flowed in by suction.

[0065] A waste particle inlet 35 is formed on a side surface of the chamber 21 , and the waste particle inlet 35 may be connected to a pipe 34 extending from a discharge hopper 18 a of the first coarse crushing unit 15 .

[0066] Furthermore, the first transfer unit 19 includes an airlock 30 that can perform an opening and closing operation. In this case, the airlock 30 may be disposed at the lower end discharge side of the cavity 31 .

[0067] Preferably, the air brake 30 can be opened and closed by the operation of an actuator such as a cylinder.

[0068] Therefore, when the airlock 30 is in a closed state, if the pump unit 29 is working, the waste particles in the discharge hopper 18a of the first coarse crushing unit 15 are transferred along the piping 34 due to suction and accumulated inside the cavity 31 through the waste particle inlet 35. As the airlock 30 is opened, the accumulated waste particles can fall downward and be loaded into a bag in the packaging unit 27a.

[0069] Figure 7 This is a perspective view showing a fine crusher of a waste crushing and transferring device according to an embodiment of the present invention. Figures 8 to 10 The present invention is a front view, a top view and a side view of a fine crusher of a waste crushing and transferring device according to an embodiment of the present invention. Figures 11 to 13 The invention is an enlarged view of a fine crusher of a waste material crushing and transferring device according to an embodiment of the present invention.

[0070] like Figures 7 to 13As shown, the fine crusher 11 is a device for crushing the waste particles in the coarse crushing state through the second crushing process. More specifically, the fine crusher 11 includes: a fine crushing input part 21, which is sequentially arranged on the frame structure, and after storing the waste particles provided from the first transfer part 19 side, it allows them to be input into the second fine crushing part 20; the second transfer part 20 is connected between the fine crushing input part 21 and the second fine crushing part 20, so that the waste particles in the fine crushing input part 21 are transferred and input into the second fine crushing part 20; the second fine crushing part 20 is arranged at the lower side of the second transfer part 22, and is crushed by the rotating second cutter 23 for fine crushing The waste particles are introduced into the second transfer section 22; the third transfer section 25 is connected between the discharge hopper 18b of the above-mentioned second crushing section 20 and the third crushing section 24, so that the waste particles in the discharge hopper 18b are transferred and introduced into the third crushing section 24; the third crushing section 24 is arranged at the lower side of the above-mentioned third transfer section 25, and the waste particles introduced into the third transfer section 25 are crushed by the rotating third cutter 26; and the fourth transfer section 28 is connected between the discharge hopper 18c of the above-mentioned third crushing section 24 and the packaging section 27b, so that the waste particles in the discharge hopper 18c are transferred and introduced into the packaging section 27.

[0071] The fine crushing input part 21 is a storage hopper, which receives the packaged waste particles from the packaging part 27 a of the primary crusher 10 and temporarily stores them before inputting them into the second fine crushing part 20 .

[0072] The waste particles may be transferred between the packaging section 27a of the coarse crusher 10 and the fine crushing input section 21 of the fine crusher 11, that is, the bagged waste particles may be directly transferred by staff or transferred by a conveyor belt.

[0073] The second transfer part 22 is connected between the crushing input part 21 and the second crushing part 20 , and can transfer the waste particles in the crushing input part 21 and input them into the second crushing part 20 by means of vacuum pressure or suction pressure.

[0074] To this end, the second transfer section 22 is supported by the upper end of the second crushing section 20 and forms a structure connected thereto. In the second transfer section 22 arranged in this manner, the suction side is connected to the discharge side of the crushing input section 21 through the pipe 34, and the discharge side is connected to the upper end inflow side of the second crushing section 20 at the lower side.

[0075] Such a second transfer section 22 includes a pump section 29 , and in this case, the waste particles can be transferred by suction provided by the pump section 29 .

[0076] Among them, the above-mentioned pump part 29 is supported by the upper end part of the cavity 31. In this case, the suction side of the pump part 29 can be connected to the interior of the cavity 31, and a grid is provided between the suction side and the interior of the cavity, thereby preventing waste particles from flowing into the pump side.

[0077] Furthermore, the second transfer unit 22 includes a cavity 31 for collecting a predetermined amount of waste particles transferred and flowed in by suction.

[0078] A waste particle inlet 35 is formed on a side surface of the chamber 31 , and the waste particle inlet 35 may be connected to a pipe 34 extending from the crushing input portion 21 .

[0079] Furthermore, the second transfer unit 22 includes an airlock 30 that can perform an opening and closing operation. In this case, the airlock 30 may be disposed at the lower end discharge side of the cavity 31 .

[0080] Preferably, the air brake 30 can be opened and closed by the operation of an actuator such as a cylinder.

[0081] Therefore, when the airlock 30 is in a closed state, if the pump unit 29 is working, the waste particles in the fine crushing input section 21 are transferred along the piping 34 due to suction and accumulated inside the cavity 31 through the waste particle inlet 35. As the airlock 30 is opened, the accumulated waste particles can fall downward and be input into the second fine crushing section 20.

[0082] The second crushing unit 20 is disposed below the second conveying unit 22 and crushes the waste particles introduced into the second conveying unit 22 by the rotating second crushing cutter 23 .

[0083] To this end, a pulley 36 and a shaft 37 are provided inside the second crushing part 20. The pulley 36 is provided at one end portion of the second crushing part 20 to receive power from a motor (not shown). Both ends of the shaft 37 are supported by bearings 54. In the shaft 37 provided in this manner, a plurality of second cutters 23 for crushing can form a coaxial structure and be connected side by side along the axis.

[0084] The rotating second crushing cutter 23 is disposed inside the second crushing section 20 and arranged side by side with the second crushing cutter 23 at a predetermined interval, and can be used together with a pair of fixed cutters (not shown) to strongly hit the waste particles and crush them.

[0085] As a preferred embodiment, the second crushing section 20 includes a cooling device, and forms a circulation structure with a freezer (not shown) side, thereby effectively cooling the heat generated when the waste particles are crushed by the second crushing cutter 23.

[0086] Moreover, the second cutter 23 for fine crushing of the above-mentioned second fine crushing section 20 is a block-shaped cutter. In this case, compared with the third cutter 26 for fine crushing of the third fine crushing section 24, the cutting width of the second cutter 23 for fine crushing is relatively wide and the number of cutting times is relatively small. Therefore, although it is compared with the third cutter 26 for fine crushing, it can crush the waste particles into a larger size, but compared with the first cutter 17 for coarse crushing included in the first coarse crushing section 15 on the coarse crusher 10 side, the crushed waste particles can be relatively small.

[0087] That is, the second cutter 23 for fine crushing of the above-mentioned second fine crushing section 20 is a block-shaped cutter, and the third cutter 26 for fine crushing of the third fine crushing section 24 is a knife-shaped cutter. Compared with the second cutter 23 for fine crushing of the second fine crushing section 20, since the cutting width of the third cutter 26 for fine crushing of the third fine crushing section 24 is relatively narrow and the number of cutting times is relatively large, the third cutter 26 for fine crushing can crush the waste particles into smaller sizes compared with the second cutter 23 for fine crushing.

[0088] Therefore, when the second crushing section 20 is working, if the waste particles thrown into the second transfer section 22 are transferred to the inside of the second crushing section 20, the waste particles pass between the rotating second crushing cutter 23 and the fixed cutter, and then fall in a crushed state and accumulate in the discharge hopper 18b on the lower side.

[0089] The third transfer unit 25 is connected between the discharge hopper 18 b of the second crushing unit 20 and the third crushing unit 24 , and transfers the waste particles in the discharge hopper 18 b to the third crushing unit 24 by vacuum pressure or suction pressure.

[0090] To this end, the third transfer section 25 is supported by the upper end of the third crushing section 24 and forms a structure connected thereto. In the third transfer section 25 arranged in this manner, the suction side is connected to the discharge hopper 18b side of the second crushing section 20 through the piping 34, and the discharge side is connected to the upper end inflow side of the third crushing section 24 at the lower side.

[0091] And, such a third transfer part 25 includes a pump part 29 , and in this case, the waste particles can be transferred by suction force provided by the pump part 29 .

[0092] Among them, the above-mentioned pump part 29 is supported by the upper end part of the cavity 31. In this case, the suction side of the pump part 29 can be connected to the interior of the cavity 31, and a grid is provided between the suction side and the interior of the cavity, thereby preventing waste particles from flowing into the pump side.

[0093] Furthermore, the third transfer unit 25 includes a cavity 31 for collecting a predetermined amount of waste particles transferred and flowed in by suction.

[0094] A waste particle inlet 35 is formed on a side surface of the chamber 21 . The waste particle inlet 35 may be connected to a pipe 34 extending from a discharge hopper 18 b of the second crushing unit 20 .

[0095] Furthermore, the third transfer unit 25 includes an airlock 30 that can perform an opening and closing operation. In this case, the airlock 30 may be disposed at the lower end discharge side of the cavity 31 .

[0096] Preferably, the air brake 30 can be opened and closed by the operation of an actuator such as a cylinder.

[0097] Therefore, when the airlock 30 is in a closed state, if the pump part 29 is working, the waste particles in the fine crushing input part 21 are transferred along the piping 34 due to suction and accumulated inside the cavity 31 through the waste particle inlet 35. As the airlock 30 is opened, the accumulated waste particles can fall downward and be put into the third fine crushing part 24.

[0098] The third crushing unit 24 is disposed below the third conveying unit 25 and crushes the waste particles introduced into the third conveying unit 25 by means of the rotating third crushing cutter 26 .

[0099] To this end, a pulley 36 and a shaft 37 are provided inside the third crushing part 24. The pulley 36 is provided at one end portion of the third crushing part 24 to receive power from a motor (not shown). Both ends of the shaft 37 are supported by bearings 54. In the shaft 37 provided in this manner, a plurality of third cutters 26 for crushing can form a coaxial structure and be connected side by side along the axis.

[0100] The rotating third crushing cutter 26 is disposed inside the third crushing section 24 and arranged side by side with the third crushing cutter 26 at a predetermined interval, and can be used together with a pair of fixed cutters (not shown) to strongly hit the waste particles and crush them.

[0101] As a preferred embodiment, the third crushing section 24 includes a cooling device, and forms a circulation structure with a freezer (not shown) side, thereby effectively cooling the heat generated when the waste particles are crushed by the third crushing cutter 26.

[0102] Moreover, the third cutter 26 for fine crushing of the above-mentioned third crushing section 24 is a knife-shaped cutter. In this case, compared with the second cutter 23 for fine crushing of the second crushing section 20, since the cutting width of the third cutter 26 for fine crushing of the third crushing section 24 is relatively narrow and the number of cutting times is relatively large, the third cutter 26 for fine crushing can crush the waste particles into smaller sizes compared with the second cutter 23 for fine crushing.

[0103] Therefore, when the above-mentioned third crushing section 24 is working, if the waste particles put into the third transfer section 25 are transferred to the inside of the third crushing section 24, the waste particles pass between the rotating third cutter 26 for crushing and the fixed cutter, and after the waste particles in the crushed state pass through the discharge hopper 18c located at the lower end of the third crushing section 24, they are loaded into the packaging section 27b through the fourth transfer section 28.

[0104] After the crushing process of the third crushing unit 24 is completed, the fourth transfer unit 28 transfers the waste particles to the packaging unit 27b side by vacuum pressure or suction pressure.

[0105] To this end, the fourth transfer section 28 is arranged on one side of the third fine crushing section 24, and the suction side of the fourth transfer section 28 is connected to the discharge hopper 18c side of the third fine crushing section 24 through the piping 34, and the discharge side is connected to the packaging section 27b on the lower side, for example, connected along the up and down directions to the packaging section 27b side formed with a bag (not shown) that can accommodate waste particles.

[0106] The fourth transfer unit 28 includes a pump unit 29 . In this case, the waste particles can be transferred by suction provided by the pump unit 29 .

[0107] Among them, the above-mentioned pump part 29 is supported by the upper end part of the cavity 31. In this case, the suction side of the pump part 29 can be connected to the interior of the cavity 31, and a grid is provided between the suction side and the interior of the cavity, thereby preventing waste particles from flowing into the pump side.

[0108] Furthermore, the fourth transfer unit 28 includes a cavity 31 for collecting a predetermined amount of waste particles transferred and flowed in by suction.

[0109] A waste particle inlet 35 is formed on a side surface of the chamber 21 , and the waste particle inlet 35 may be connected to a pipe 34 extending from a discharge hopper 18 c of the third crushing unit 24 .

[0110] Furthermore, the fourth transfer unit 19 includes an airlock 30 that can perform an opening and closing operation. In this case, the airlock 30 may be disposed at the lower end discharge side of the cavity 31 .

[0111] Preferably, the air brake 30 can be opened and closed by the operation of an actuator such as a cylinder.

[0112] Therefore, when the airlock 30 is in a closed state, if the pump section 29 is working, the waste particles in the discharge hopper 18c of the third crushing section 28 are transferred along the piping 34 due to suction and accumulated inside the cavity 31 through the waste particle inlet 35. As the airlock 30 is opened, the accumulated waste particles can fall downward and be loaded into bags in the packaging section 27b.

[0113] Figures 14 to 17 It is a cross-sectional view showing the cooling device of the second and third crushing parts in the crusher of the waste material crushing and transferring device according to one embodiment of the present invention.

[0114] like Fig.14 and Fig.15 As shown, the cutter support 39 is in the form of a plurality of combinations, and is used to support the second cutter 23 for crushing of the second crushing part 20, and is combined with the shaft 37 in a coaxial structure. Moreover, a cooling water cavity 40 is formed inside each cutter support 39, and each cooling water cavity 40 is connected by a flow path 41 to form an interconnected structure. Each support block 42 combined on the shaft 37 serves as the end of the cutter support 39 located at the edges of both sides, and a cooling water flow direction conversion cavity 43 connected to the cooling water cavity 40 is formed inside.

[0115] Among them, the above-mentioned cooling water cavity 40 and the cooling water flow direction conversion cavity 43 are respectively composed of two independent and separate parts, thereby, the cooling water cavity 40 and the cooling water flow direction conversion cavity 43 on one side will become the area where the cooling water flows in, and the cooling water cavity 40 and the cooling water flow direction conversion cavity 43 on the other side will become the area where the cooling water flows out.

[0116] Furthermore, an inlet side cooling water flow path 44 and an outlet side cooling water flow path 45 are formed at one end of the shaft 37. The inlet side cooling water flow path 44 is connected to the cooling water cavity 40 on one side, and the outlet side cooling water flow path 45 is connected to the cooling water cavity 40 on the other side.

[0117] An inlet 46 and an outlet 47 connected to a cooling water supply source (not shown) such as a refrigerator are formed at one end of the shaft 37, and a connecting block 48 connected to the inlet side cooling water flow path 44 and the outlet side cooling water flow path 45 of the shaft 37 is provided.

[0118] Thus, the cooling water supplied from the cooling water supply source side flows along the circulation path of the inlet 46 → the inlet side cooling water flow path 44 → the cooling water flow to the conversion chamber 43 on one side → the cooling water chamber 40 on one side → the cooling water flow to the conversion chamber 43 → the cooling water chamber 40 on the other side → the cooling water flow to the conversion chamber 43 on the other side → the outlet side cooling water flow path 45 → the outlet 47 → the cooling water supply source side, and cools the entire support block 42 including the second cutter 23 for fine crushing. In this case, a seal 55 and a seal fixing portion 56 for preventing leakage of cooling water are provided at the end of the shaft 37.

[0119] Furthermore, the support blocks 42 are provided at both ends of the cutter support 39, and blades 53 are provided at the ends of the support blocks 42 to rotate in conjunction with the shaft 37. In this case, the blades 53 can prevent dust generated by the crushing operation of the second cutter 23 for crushing from flowing to the bearing 54 side. More specifically, the second crushing section 20 includes an air inlet 58, and the air inlet 58 allows compressed air supplied by an air compressor (not shown) to flow into the inside. The compressed air entering through the air inlet 58 can flow in the opposite direction of the bearing 54 by the rotation of the blades 53, that is, can flow toward the center of the cutter support 39. In other words, dust scattered in the gap between the housing 49 and the cutter support 39 can be prevented from being transferred to the bearing 54 side by the compressed air supplied through the air inlet 58 and the blades 53. Furthermore, since the end of the bearing is provided with a fixer 54 , a secondary barrier for preventing dust from moving toward the bearing 54 can be realized.

[0120] If the blades 53 are not provided, the dust generated during the crushing process may adhere to the shaft 37 and the bearing 54 through the gaps. Therefore, by providing the blades 53 at both ends of the second crushing unit 20, the dust scattered through the gaps is prevented from moving to the bearing 54 side, thereby preventing the dust from adhering to the shaft 37 and the bearing 54 and causing frictional heat during the rotation process. Fig.14 The blade 53 disposed on the right side of the support block 42 can prevent the dust generated during the crushing operation of the second cutter 23 for crushing from moving to the right side by transferring the compressed air supplied through the air inlet 58 to the left side. In addition, the holder 57 is disposed on the left side of the bearing 54 to prevent the dust from moving toward the bearing 54 again. In addition, the second crushing part 20 can be cooled by the flow of the compressed air. Since the compressed air provided is discharged toward the outside of the housing 49 through the outer peripheral surface of the support block 42, the increase of the inner pressure can be prevented.

[0121] like Fig.16 As shown, the cutter support 39 is in the form of a plurality of combinations, and is used to support the third cutter 26 for fine crushing of the third fine crushing part 24, and is combined with the shaft 37 in a coaxial structure. Moreover, a cooling water cavity 40 is formed inside each cutter support 39, and each cooling water cavity 40 is connected by a flow path 41 to form an interconnected structure. Each support block 42 combined on the shaft 37 serves as the end of the cutter support 39 located at the edges of both sides, and a cooling water flow direction conversion cavity 43 connected to the cooling water cavity 40 is formed inside.

[0122] Among them, the above-mentioned cooling water cavity 40 and the cooling water flow direction conversion cavity 43 are respectively composed of two independent and separate parts, thereby, the cooling water cavity 40 and the cooling water flow direction conversion cavity 43 on one side will become the area where the cooling water flows in, and the cooling water cavity 40 and the cooling water flow direction conversion cavity 43 on the other side will become the area where the cooling water flows out.

[0123] Furthermore, an inlet side cooling water flow path 44 and an outlet side cooling water flow path 45 are formed at one end of the shaft 37. The inlet side cooling water flow path 44 is connected to the cooling water cavity 40 on one side, and the outlet side cooling water flow path 45 is connected to the cooling water cavity 40 on the other side.

[0124] An inlet 46 and an outlet 47 connected to a cooling water supply source (not shown) such as a refrigerator are formed at one end of the shaft 37, and a connecting block 48 connected to the inlet side cooling water flow path 44 and the outlet side cooling water flow path 45 of the shaft 37 is provided.

[0125] Thus, the cooling water provided from the cooling water supply source side can flow according to the circulation path of the inlet 46 → the inlet side cooling water flow path 44 → the cooling water flow to the conversion cavity 43 on one side → the cooling water cavity 40 on one side → the cooling water flow to the conversion cavity 43 → the cooling water cavity 40 on the other side → the cooling water flow to the conversion cavity 43 on the other side → the outlet side cooling water flow path 45 → the outlet 47 → the cooling water supply source side and cool the entire support block 42 including the third cutter 26 for fine crushing.

[0126] like Fig.17 As shown, the cooling structure of the housing 49 of the second crushing part 20 and the third crushing part 24 is shown.

[0127] A cooling water cavity 40 is formed inside the housing 49 , and cooling water cavities 40 are also formed on both side housing frames 50 supporting the housing 49 . In this case, each cooling water cavity 40 is connected through a flow path 41 .

[0128] Moreover, the cavity 40 of the outer shell frame 50 on one side is connected to the inlet side tube joint 51 for the inflow of cooling water, and at the same time, the cavity 40 of the outer shell frame 50 on the other side is connected to the outlet side tube joint 52 for discharging cooling water. In this case, the inlet side tube joint 51 and the outlet side tube joint 52 form a circulation line with the cooling water supply source side.

[0129] Therefore, the cooling water provided by the cooling water supply source layer can flow according to the circulation path of the inlet side tube joint 51 → the cavity 40 of the outer shell frame 50 on one side → the cavity 40 of the outer shell 49 → the cavity 40 of the outer shell frame 50 on the other side → the outlet side tube joint 52 → the cooling water supply source side and cool the entire outer shell 49.

[0130] Therefore, the waste material crushing and transferring device having the above-mentioned structure is in the working state as described below.

[0131] First, waste materials such as rubber materials left over from manufacturing shoe soles are hung on the hanger 12 located at the coarse crushing input part 14 of the coarse crusher 10, and the waste materials are crushed into relatively coarse waste particles through the coarse crushing input hopper part 16 → first coarse crushing part 15 → first transfer part 19 → packaging part 27a.

[0132] Next, the waste particles crushed for the first time by the coarse crusher 10 are crushed into relatively fine waste particles through the crushing input part 21 of the fine crusher 11 → the second transfer part 22 → the second fine crushing part 20 → the third transfer part 25 → the third fine crushing part 24 → the fourth transfer part 28 → the packaging part 27b.

[0133] After the secondary coarse crushing process and the fine crushing process, the finely crushed waste particles can be used for various purposes and recycled.

[0134] On the other hand, as a preferred embodiment, the present invention can provide a construction layout that combines the coarse crusher 10 and the fine crusher 11 into an integrated unit form, so that the coarse crushing process of the coarse crusher 10 and the fine crushing process of the fine crusher 11 can be realized through a continuous automated line.

[0135] To this end, the coarse crusher 10 and the fine crusher 11 need to be arranged in series or in parallel on the process line, and the discharge hopper 15a of the first coarse crushing unit 15 of the coarse crusher 10 needs to be connected to the second transfer unit 22 of the fine crusher 11 through the pipe 34.

[0136] Of course, the first transfer unit 19 on the coarse crusher 10 side and the fine crushing input unit 21 on the fine crusher 11 side may be omitted.

[0137] Thus, a layout of a continuous automated line can be constructed, where the waste is roughly crushed once in the coarse crusher 10 , so that the waste particles discharged after the first crushing are directly transferred to the fine crusher 11 and undergo a secondary fine crushing process through the fine crusher 11 .

[0138] When a layout of a continuous automated line is constructed by connecting the coarse crusher 10 for the coarse crushing process and the fine crusher 11 for the fine crushing process, not only can the efficiency of the overall process and the efficiency of equipment operation be maximized, but also advantages in terms of factory layout design can be obtained.

[0139] As a result, the waste crushing and transferring device of the present invention can realize recycling by crushing and transferring the waste rubber materials, waste shoes and other rubber materials left after manufacturing insoles, etc., and can collect the dust generated during the crushing process to minimize the damage of the crushing device or the transfer device due to accumulated dust.

[0140] That is, the present invention can provide a new type of waste crushing and transferring device and a conveyor for conveying crushed particles. Waste materials such as rubber materials generated in the manufacturing process of insoles, etc. are crushed by first performing a primary coarse crushing process and a secondary fine crushing process to make the particles fine. This can completely solve the environmental pollution problem and prevent malfunctions due to dust, and can achieve economic advantages by recycling resources.

[0141] It should be understood that, without changing the technical concept or essential features of the present invention, a person skilled in the art can implement the technical structure of the present invention as described above through other specific implementations.

[0142] Therefore, the embodiments described above are merely examples at all levels and should not be understood as limiting. The scope of the present invention should be represented by the scope of protection claimed in the invention rather than the above detailed description. All changes or modifications derived from the meaning, scope and equivalent concepts of the scope of protection claimed in the invention belong to the scope of the present invention.
