[0002] Waste spinning, cloth, leather and the like are common soft solid wastes generated in family or commercial activities. At present, waste spinning and other solid wastes are almost the kind with the lowest recycling and disposal rate in all garbage. For the treatment of soft solid waste, two ways are adopted in the related art, which are as follows.

[0003] I. The traditional landfill treatment is adopted for the soft solid waste, but this treatment not only pollutes the environment and increases carbon emission, but also causes great waste of resources;

[0004] II. The soft solid waste is incinerated for utilization, especially through coupling incineration for utilization in widely distributed coal-fired power plants. Due to the characteristics of coal powder boiler and other facilities, the particle size of waste spinning and other materials entering the boiler needs to meet certain size requirements. At present, the size of textile is mainly reduced through a shredder, so as to be incinerated. However, the textile often contains a large amount of fibers and has high toughness, so it is difficult and inefficient to shred. In addition, the service life of the shredder cutter is generally short, so the equipment maintenance cost is high. At the same time, the crushing size of the shredding equipment is difficult to be less than 4cmx4cm. In addition, it is difficult to collect the dust generated in the crushing process, and the environmental protection needs to be improved. SUMMARY

DETAILED DESCRIPTION

[0037] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0038] As shown in Figure 1 and Figure 2 A flexible solid waste crushing device according to an embodiment of the present application includes a base 1, a thermal crushing platform 2, and a first heating member.

[0039] The thermal crushing platform 2 is arranged on the base 1 and includes a plurality of first thermal crushing ribs 21 and a plurality of second thermal crushing ribs 22. The plurality of first thermal crushing ribs 21 are arranged in a left-right direction and each extends in a front-rear direction. The plurality of second thermal crushing ribs 22 are arranged in the front-rear direction and each extends in the left-right direction. The plurality of first thermal crushing ribs 21 and the plurality of second thermal crushing ribs 22 are connected in a cross manner and form a first thermal crushing grid together.

[0040] The first heating member is connected to the first thermal crushing grid. The first thermal crushing grid is used to pyrolyze large pieces of flexible solid waste into small pieces of flexible solid waste with a mesh size consistent with the first thermal crushing grid.

[0041] According to the flexible solid waste crushing device of the embodiment of the present application, the first thermal crushing grid structure is formed by the cooperation of the first thermal crushing ribs 21 and the second thermal crushing ribs 22. Under the heating action of the first heating member, the first thermal crushing grid structure can pyrolyze large pieces of flexible solid waste placed thereon into small pieces of flexible solid waste with a mesh size consistent with the first thermal crushing grid. Compared with the shredder used in the related art to shred the flexible solid waste, the crushing device in the present application realizes the crushing of the flexible solid waste by pyrolysis. The crushing process is not affected by the toughness of the flexible solid waste itself, and the crushing difficulty is low, the crushing effect is good, and the crushing efficiency is high. According to the crushing size requirements of the flexible solid waste, the first thermal crushing grid with a matching mesh size can be replaced to meet the crushing size control of the flexible solid waste, so that the crushing size can be below 2 mm. Since the entire crushing process is pyrolysis, the wear of the equipment is small compared with the crushing by the shredding cutter in the related art, which ensures the service life of the equipment and reduces the maintenance cost of the equipment.

[0042] Specifically, the first thermal crushing ribs 21 and the second thermal crushing ribs 22 can be, but are not limited to, steel members. The first thermal crushing ribs 21 and the second thermal crushing ribs 22 can be connected in a welding manner. The first thermal crushing grid can be, but is not limited to, a grid structure.

[0043] It can be understood that the intervals between the plurality of first thermal broken ribs 21 can be equal or unequal, and the adjacent first thermal broken ribs 21 can be parallel or non-parallel, and the arrangement between the plurality of second thermal broken ribs 22 is the same, so it is only necessary to ensure that the first thermal broken rib 21 and the second thermal broken rib 22 are connected and can form a mesh, therefore, the first thermal broken grid structure in the application has low processing difficulty and low processing cost.

[0044] In addition, in order to further broaden the use performance of the crushing device and meet the requirements of various crushing sizes of the soft solid waste, the first thermal broken grid can also be designed as a mesh structure with adjustable mesh size, that is, the interval between adjacent first thermal broken ribs 21 can be adjusted, and the interval between adjacent second thermal broken ribs 22 can be adjusted. The specific structure and adjustment method can adopt the existing technology in the art, which will not be extended here.

[0045] As shown in Figure 1 In some embodiments, the soft solid waste crushing device further comprises a first pressing cover 3, and the first pressing cover 3 has a first idle position and a first working position. In the first idle position, the first pressing cover 3 is spaced apart from the first thermal broken grid, and in the first working position, the first pressing cover 3 is pressed against the first thermal broken grid and forms a thermal broken cavity between the first thermal broken grid for accommodating the large block of soft solid waste.

[0046] Through the first pressing cover 3, the large block of soft solid waste can be pressed against the first thermal broken grid to assist the first thermal broken grid in improving the pyrolysis efficiency of the large block of soft solid waste, and the first pressing cover 3 can also be isolated from the outside to ensure the pyrolysis temperature of the thermal broken cavity and reduce energy waste caused by heat loss.

[0047] Specifically, the surface of the first pressing cover 3 away from the first thermal broken grid can be provided with a handle, and the operator can press the first pressing cover 3 on the first thermal broken grid or remove it by holding the handle. The first thermal broken grid has a working surface, and the large block of soft solid waste to be pyrolyzed is placed on the working surface for pyrolysis. In the first working position, at least part of the first pressing cover 3 can completely cover the working surface of the first thermal broken grid.

[0048] As shown in Figure 1 In some embodiments, the first pressing cover 3 is provided with a gas outlet 31 communicating with the thermal broken cavity, and the gas outlet 31 is connected with a pyrolysis gas treatment and recovery device through an induced draft fan.

[0049] The induced draft fan is used to suck the pyrolysis oil gas generated in the pyrolysis process of the soft solid waste into the pyrolysis gas treatment and recovery device through the gas outlet 31, so as to effectively avoid environmental pollution caused by direct discharge of the pyrolysis oil gas into the outside air, and improve the environmental protection performance of the crushing device. In addition, compared with the related art, the crushing device uses pyrolysis method to crush the soft solid waste, and only pyrolysis oil gas is generated in the crushing process, which is convenient for collection.

[0050] Specifically, to further improve the energy utilization rate, the pyrolysis oil gas drawn from the gas outlet 31 by the induced draft fan can also be reflowed into the pulverized coal boiler to utilize the heat and oil gas in the pyrolysis oil gas to provide energy for the combustion of the pulverized coal boiler. At this time, the output end of the induced draft fan is in communication with the pulverized coal boiler, and the pyrolysis gas treatment and recovery device can no longer be connected.

[0051] As shown in Figure 1 and Figure 2 In some embodiments, the flexible solid waste crushing device further comprises a second heating member and a plurality of third heat breaking ribs 32 and a plurality of fourth heat breaking ribs 33 arranged on the lower surface of the first gland 3.

[0052] The plurality of third heat breaking ribs 32 are arranged in the left-right direction and each extend in the front-rear direction, and the plurality of fourth heat breaking ribs 33 are arranged in the front-rear direction and each extend in the left-right direction. The plurality of third heat breaking ribs 32 and the plurality of fourth heat breaking ribs 33 are cross-connected and jointly form a second heat breaking grid, and the second heat breaking grid is connected to the second heating member.

[0053] In the first working position, the third heat breaking ribs 32 correspond one-to-one to the first heat breaking ribs 21, and the fourth heat breaking ribs 33 correspond one-to-one to the second heat breaking ribs 22, and the second heat breaking grid is pressed against the large block of flexible solid waste.

[0054] The second heat breaking grid is designed on the lower surface of the first gland 3 to cooperate with the first heat breaking grid to form a simultaneous pyrolysis of the upper and lower surfaces of the large block of flexible solid waste during the pyrolysis process, further effectively improving the pyrolysis and crushing efficiency of the flexible solid waste.

[0055] Specifically, the third heat breaking ribs 32 and the fourth heat breaking ribs 33 can be, but are not limited to, steel members, and the third heat breaking ribs 32 and the fourth heat breaking ribs 33 can be connected in a manner other than welding. The second heat breaking grid can be, but is not limited to, a grid structure.

[0056] Similar to the arrangement of the first heat breaking ribs 21 and the second heat breaking ribs 22, the third heat breaking ribs 32 and the fourth heat breaking ribs 33 are arranged on the lower surface of the first gland 3 corresponding to the first heat breaking ribs 21 and the second heat breaking ribs 22, and can be fixed to the first gland 3 in a manner other than welding or bolt connection. In addition, the second heat breaking grid structure can also be adjustable to match the first heat breaking grid structure, which will not be specifically expanded here.

[0057] As shown in Figure 1As shown, in some embodiments, the flexible solid waste crushing device further includes a second pressure cover 4. The lower surface of the second pressure cover 4 is arrayed with discharge protrusions 41. The second pressure cover 4 has a second idle position and a second working position. The second pressure cover 4 is spaced apart from the first thermal crushing grid in the second idle position. In the second working position, the second pressure cover 4 presses against the first thermal crushing grid. The discharge protrusions 41 are matched with the mesh and correspond one-to-one. The discharge protrusions 41 are matched with the corresponding mesh to facilitate pressing small pieces of flexible solid waste out of the mesh.

[0058] After large pieces of soft solid waste are pyrolyzed into smaller pieces, the smaller pieces of soft solid waste can be pressed out through the mesh by the second pressure cap 4 and the discharge protrusion 41 on it, so as to realize the discharge of soft solid waste after pyrolysis. The operation is simple and the structure is ingenious.

[0059] Specifically, a handle may be provided on the surface of the second cover 4 away from the first thermal rupture grid. The operator can press or remove the second cover 4 on the first thermal rupture grid by holding the handle. Similar to the first cover 3, in the second working position, at least a part of the second cover 4 can completely press the working surface of the first thermal rupture grid.

[0060] In addition, the discharge protrusion 41 can be integrally formed on the lower surface of the second pressure cover 4.

[0061] like Figure 1 As shown, in some embodiments, the thermal crushing platform 2 further includes a discharge hopper 23, which includes an inlet and an outlet. The inlet is located below the first thermal crushing grid and communicates with each mesh. The outlet is communicated with the inlet and is used to discharge small pieces of soft solid waste.

[0062] Specifically, the feed inlet can be fixedly connected to the edge of the lower surface of the first thermal crushing grid so that all the mesh of the first thermal crushing grid is located in the feed inlet, thus facilitating the discharge of small pieces of soft solid waste.

[0063] like Figure 1 As shown, in some embodiments, the flexible solid waste crushing device also includes a discharge gate, which is movably connected to the discharge hopper 23 between a blocked position for sealing the discharge port and an open position for opening the discharge port.

[0064] The material discharge hopper 23 and the discharge gate work together to achieve centralized discharge of small pieces of soft solid waste after they are discharged from the first thermal crushing grid. At the same time, during the pyrolysis process, the discharge gate blocks the outlet and can work with the first pressure cover 3 to provide a sealed space for the pyrolysis of soft solid waste, which not only ensures the pyrolysis efficiency, but also avoids the environmental pollution caused by the pyrolysis oil and gas entering the outside air.

[0065] Specifically, the discharge door is pivotally or movably connected to the material falling hopper 23, that is, the discharge door is rotatable on the material falling hopper 23 to block or open the discharge port, and in order to ensure good closure of the discharge door and the discharge port, a pressing mechanism can be used to press the discharge door against the discharge port, the pressing mechanism can be of the prior art in the field, and specific reference can be made to the existing discharge door structure, or the discharge door is slidable on the material falling hopper 23 to block or open the discharge port, which will not be described here.

[0066] As shown in Figure 1 In some embodiments, the first pressing cover 3 and the second pressing cover 4 are both connected to the base 1.

[0067] The first heating element and the second heating element are both electric heating wires, the first heating element is pre-embedded in the first heat-breaking grid, and the second heating element is pre-embedded in the second heat-breaking grid.

[0068] Connecting the first pressing cover 3 and the second pressing cover 4 to the base 1 ensures the integrity of the crushing device, and using the electric heating wires pre-embedded in the first heat-breaking grid or the second heat-breaking grid as the first heating element and the second heating element has the advantages of simple structure and reliable heating effect.

[0069] Specifically, the first pressing cover 3 and the second pressing cover 4 are both pivotally connected to the base 1 to facilitate switching of the first pressing cover 3 between the first working position and the first idle position and switching of the second pressing cover 4 between the second working position and the second idle position, and the electric heating wires can be embedded along the first heat-breaking rib 21 and the second heat-breaking rib 22 of the first heat-breaking grid or the third heat-breaking rib 32 and the fourth heat-breaking rib 33 of the second heat-breaking grid to ensure uniformity and reliability of heating.

[0070] In some embodiments, the flexible solid waste crushing device further comprises a briquetting mechanism for pressing a plurality of flexible solid wastes into a large piece of flexible solid waste.

[0071] Using the briquetting mechanism, a plurality of flexible solid wastes can be first pressed into a large piece of flexible solid waste to improve the processing efficiency of the crushing device for batches of flexible solid wastes, and the operation arrangement of first pressing and then crushing and processing the flexible solid wastes is more scientific and reasonable.

[0072] Specifically, the briquetting mechanism can be a garbage briquetting machine of the prior art in the field.

[0073] As shown in Figure 1 and Figure 2 According to the flexible solid waste crushing method of an embodiment of the present application, based on the above flexible solid waste crushing device, the method comprises the following steps:

[0074] Placing the large piece of flexible solid waste on the first heat-breaking grid;

[0075] The first heating member heats the first thermal breaking grid, and the large flexible solid waste is pyrolyzed into small flexible solid wastes consistent with the mesh specifications of the first thermal breaking grid.

[0076] The technical advantages of the flexible solid waste breaking method according to the embodiments of the present application are the same as those of the flexible solid waste breaking device, which will not be repeated here.

[0077] Specifically, one large flexible solid waste can be placed on the first thermal breaking grid, or multiple large flexible solid wastes can be laid flat on the first thermal breaking grid, and the thickness of the multiple large flexible solid wastes can be consistent or inconsistent. In addition, when the thickness of the multiple large flexible solid wastes is inconsistent, the same size flexible solid waste can also be stacked on the first thermal breaking grid to improve the processing efficiency of the batch of large flexible solid wastes, and the thickness of the large flexible solid waste at this position is consistent with that of the large flexible solid waste at other positions to realize the one-time pyrolysis and breaking of multiple flexible solid wastes.

[0078] In some embodiments, after the large flexible solid waste is placed on the first thermal breaking grid, the first pressing cover 3 is pressed against the large flexible solid waste, the first pressing cover 3 is in the first working position, and the second heating member heats the second thermal breaking grid.

[0079] In some embodiments, after the first thermal breaking grid is heated by the first heating member, the large flexible solid waste is pyrolyzed into small flexible solid wastes consistent with the mesh specifications of the first thermal breaking grid, the first pressing cover 3 is removed from the first thermal breaking grid, the first pressing cover 3 is in the first idle position, the second pressing cover 4 is pressed against the first thermal breaking grid, the second pressing cover 4 is in the second working position, and the discharge protrusion 41 pushes the small flexible solid wastes out of the mesh of the first thermal breaking grid.

[0081] The second pressing cover 4 is pressed against the first thermal breaking grid, the second pressing cover 4 is in the second working position, and the discharge protrusion 41 pushes the small flexible solid wastes out of the mesh of the first thermal breaking grid.

[0082] The second pressing cover 4 is removed from the first thermal breaking grid, and the second pressing cover 4 is in the second idle position.

[0083] In some embodiments, before the large flexible solid waste is placed on the first thermal breaking grid, the multiple flexible solid wastes are pressed into one large flexible solid waste by the briquetting mechanism.

[0088] 4) control the first heating element and the second heating element to work, the heating wire heats the first thermal breaking grid and the second thermal breaking grid, at the same time, the bulk flexible solid waste in the thermal breaking cavity is pyrolyzed into small pieces of flexible solid waste consistent with the mesh specification, in this process, the pyrolysis oil gas is sucked into the pyrolysis gas treatment and recovery device under the action of the induced draft fan for treatment;

[0089] 5) remove the first grommet 3 on the first thermal breaking grid;

[0090] 6) press the second grommet 4 against the first thermal breaking grid, and open the discharge door, at this time, the discharge convex 41 pushes the small pieces of flexible solid waste out of the mesh of the first thermal breaking grid, and the small pieces of flexible solid waste slide along the feed port of the discharge hopper 23 to the discharge port and are discharged from the discharge door, thereby completing the discharge operation after the pyrolysis of the flexible solid waste;
