Description

Technical Field

[0001] This invention relates to the field of industrial waste textile multi-stage crushing equipment, specifically to an industrial waste textile multi-stage crushing equipment and crushing process for RDF (Reactive Fuel Dioxide) production. Background Technology

[0002] The multi-stage crushing equipment for industrial waste textiles used in the production of RDF (Refuse-Derived Fuel) is a device used to process industrial waste textiles. Its main function is to crush waste textiles into smaller particles or fibers. These waste textiles can be waste fabrics, old clothes, waste cloth, waste yarn, etc. By using crushing equipment, waste textiles can be reused. It also has the characteristics of simple structure, convenient operation, and low energy consumption. The multi-stage crushing equipment for industrial waste textiles used in the production of RDF is an important waste textile processing equipment that can effectively solve the problem of waste textile processing and reuse.

[0003] Patent CN216987845U discloses a crushing device for industrial solid waste disposal, including a crushing box. A crushing cylinder is symmetrically rotatably connected to the rear end face of the crushing box via an mounting axis. A drive motor is fixedly connected to the rear end face of the crushing box, and the output shaft of the drive motor is fixedly connected to the mounting shaft. A placement box is fixedly connected to the right side wall of the crushing box, and a dust collection mechanism is fixedly connected to the right side wall of the crushing box. The air outlet of the dust collection mechanism is connected to a dust collection pipe, and a threaded sleeve is threadedly connected to the lower end face of the dust collection pipe. A dust collector bag is rotatably connected to the lower end face of the threaded sleeve. Mounting blocks are symmetrically fixedly connected to the right side wall of the placement box. This technical solution solves the problems of existing industrial solid waste crushing equipment generating large amounts of dust during crushing, making dust collection and filtration inconvenient, and the difficulty in replacing worn crushing teeth.

[0004] However, the above-mentioned industrial solid waste crushing equipment has the following problems: when the crushing equipment is used, the waste textile contains moisture, which leads to poor crushing effect on the waste textile containing moisture. Therefore, we propose a multi-stage crushing equipment for industrial waste textiles for RDF production as an alternative fuel. Summary of the Invention

[0005] This invention proposes a multi-stage crushing device and crushing process for industrial waste textiles used in the production of alternative fuel RDF, which solves a problem in related technologies regarding multi-stage crushing devices for industrial waste textiles used in the production of alternative fuel RDF.

[0006] The technical solution of the present invention is as follows: A multi-stage crushing device for industrial waste textiles used in the production of alternative fuel RDF includes a machine casing and a crushing circular shell. The crushing circular shell is penetrated and fixed in the middle of the top surface of the machine casing. The device includes a filter press, a cutting device, a distribution device and a cloth rolling device. The filter press is located in the middle of the left side of the machine casing. The cutting device is located in the middle of the back side of the machine casing. The distribution device is located on the bottom surface of the cutting device and the cloth rolling device is located on the bottom surface of the machine casing.

[0007] The filter press includes an L-shaped plate, a U-shaped feed plate, two semi-arc plates, a drive unit, and a pressing roller. The L-shaped plate is fixed to the middle of the left side of the machine casing, and the U-shaped feed plate is fixed to the top surface of the L-shaped plate. The U-shaped feed plate is inclinedly arranged on the L-shaped plate. The two semi-arc plates are respectively fixed to the top surface of the U-shaped feed plate. The drive unit includes a protective shell and a motor. The protective shell is fixed to the back of the semi-arc plates, and the motor is fixed to the front of the inner wall of the protective shell. The motor shaft passes through and is rotatably installed on the back of the semi-arc plates. The pressing roller is fixed to the front of the motor shaft of the drive unit and is rotatably arranged between the two semi-arc plates. The liquid outlet of the U-shaped feed plate is opened on the bottom surface of the U-shaped feed plate. The pressing roller crushes the waste textiles in the U-shaped feed plate, squeezing out the water contained in the waste textiles, thus avoiding the poor decomposition effect of multi-stage industrial waste textile crushing equipment on waste textiles containing moisture.

[0008] The filter press also includes a semi-circular liquid collection tank, a square shell, and a liquid outlet pipe. The semi-circular liquid collection tank is fixed to the bottom surface of the U-shaped inlet plate and is located on the bottom surface of the liquid outlet of the U-shaped inlet plate. The square shell is fixed in the middle of the bottom surface of the semi-circular liquid collection tank, and the liquid outlet pipe passes through and is fixed in the middle of the bottom surface of the square shell. The liquid outlet pipe discharges waste textile wastewater, avoiding the inconvenience of wastewater accumulation caused by the multi-stage crushing equipment for industrial waste textiles.

[0009] The feed hopper of the crushed cylindrical shell is fixed to the top surface of the crushed cylindrical shell. The U-shaped feed plate is inclinedly arranged on the inner wall of the feed hopper of the crushed cylindrical shell. A filter screen is installed in the liquid outlet of the U-shaped feed plate, and the liquid outlet of the U-shaped feed plate is located below the crushing roller.

[0010] The cutting device includes a shaped plate, a second drive unit, a rotating rod, several annular blocks, and four blades. The shaped plate is fixed to the middle of the back of the machine casing. The second drive unit includes a protective shell and a motor. The motor is fixedly installed inside the top of the protective shell. The motor of the second drive unit is rotatably mounted on the top surface of the shaped plate. The rotating rod is fixed to the bottom surface of the motor of the second drive unit and is located in the middle of the crushing shell. Several annular blocks are respectively fixed to the outer wall of the rotating rod, and the several annular blocks are staggered on the rotating rod. The four through-holes of the several annular blocks are respectively opened on the bottom surface of the several annular blocks. The four blades are respectively fixed to the outer wall of the several annular blocks. The blades rotate clockwise to cut larger waste textiles, avoiding the difficulty of decomposing larger waste textiles in multi-stage industrial waste textile crushing equipment.

[0011] The cutting device also includes four L-shaped rods, four U-shaped long plates, and four rubber sheets. The four L-shaped rods are respectively fixed to the inner walls of the four through holes of several annular blocks. The four U-shaped long plates are respectively fixed to the top surfaces of the four L-shaped rods. The four rubber sheets are respectively fixed to the inner walls of the four U-shaped long plates. The rubber sheets prevent larger waste textiles from falling downwards, thus avoiding poor decomposition effect when industrial waste textile multi-stage crushing equipment cuts larger waste textiles.

[0012] The distribution device includes a cylinder, four inclined rods, a ring, and several spring plates. The cylinder is fixed to the bottom surface of the rotating rod, the four inclined rods are respectively fixed to the bottom of the outer wall of the cylinder, the ring is fixed to the bottom surface of the four inclined rods, and the several spring plates are respectively fixed to the inner wall of the ring. The pre-shredded waste textiles are evenly shaken downwards, preventing the pre-shredded waste textiles in the multi-stage industrial waste textile crushing equipment from falling downwards haphazardly.

[0013] The distribution device also includes four L-shaped support rods, four grooved vertical blocks, and four chamfered pieces. The four L-shaped support rods are respectively fixed in the middle of the top surface of the four inclined rods. The four grooved vertical blocks are respectively fixed on the front of the four L-shaped support rods. The four chamfered pieces are respectively fixed on the inner wall of the groove of the four grooved vertical blocks. The four chamfered pieces are rotatably set at the bottom of the inner wall of the crushing shell. When the chamfered pieces rotate clockwise, they scrape off the waste textile yarn attached to the crushing shell, thus avoiding the inconvenience of cutting caused by the yarn adhering to the multi-stage crushing equipment for industrial waste textiles.

[0014] The fabric grinding device includes a square box, a third drive unit, two cutting rollers, and two inclined plates. The square box is fixed to the bottom of the machine casing. The third drive unit includes a protective shell and a dual-axis motor. The dual-axis motor is fixedly installed inside the protective shell on the front side. The two shafts of the dual-axis motor of the third drive unit pass through and are rotatably installed on the back of the square box. The two cutting rollers are respectively fixed to the front of the two shafts of the dual-axis motor. The two inclined plates are respectively fixed to the front and back of the inner wall of the square box. The inclined plates restrict the initially shredded waste textiles to the cutting rollers, avoiding the inconvenience of decomposing small particles in multi-stage industrial waste textile crushing equipment, which would result in poor decomposition effect. A discharge port is opened at the bottom right side of the square box. The opposite surfaces of the two cutting rollers mesh with each other. The two inclined plates are respectively set on the top surface of the two cutting rollers, and the opposite surfaces of the two inclined plates are set as a sliding surface.

[0015] The fabric crushing device also includes two long strip clamps, two arc-shaped spring pieces, and two scraper blades. The two long strip clamps are respectively fixed to the back of two inclined plates, and a groove is provided in the middle of the back of the two long strip clamps. The two arc-shaped spring pieces are respectively fixed to the inner wall of the groove of the two long strip clamps. The two scraper blades are respectively fixed to the end of the two arc-shaped spring pieces away from the two long strip clamps. The two scraper blades are respectively set on the outer wall of the two fabric cutting rollers. The scraper blades scrape off the fibers adhering to the fabric cutting rollers, avoiding damage to the industrial waste textile multi-stage crushing equipment caused by the fibers of waste textiles becoming entangled.

[0016] A crushing process, employing the aforementioned multi-stage crushing equipment for industrial waste textiles used in RDF (Reactive Fuel Dioxide) production, includes the following steps:

[0017] S1. The roller in the semi-arc plate rotates forward, and the roller crushes the waste textile in the U-shaped feed plate.

[0018] S2. The semi-circular liquid collection tank collects water, which continues to flow downwards into the square shell. The water in the square shell flows downwards into the liquid outlet pipe, which discharges the waste textile wastewater.

[0019] S3. The ring block drives the blade to rotate forward, and the forward rotation of the blade will cut larger waste textiles into shreds.

[0020] S4. The U-shaped long plate drives the rubber sheet to rotate in the forward direction, and the rubber sheet prevents larger waste textiles from falling downwards.

[0021] S5. The diagonal bar drives the ring to rotate clockwise, and the ring drives the spring plate to rotate clockwise. The initially shredded waste textiles fall onto the spring plate on the ring.

[0022] S6. The grooved vertical block drives the chamfering plate to rotate clockwise, and the clockwise rotation of the chamfering plate scrapes off the waste textile yarn attached to the broken round shell.

[0023] S7. The relative rotation of the cutting rollers crushes and squeezes the initially shredded waste textiles, while the inclined plate restricts the initially shredded waste textiles onto the cutting rollers.

[0024] S8. The scraper blade removes the fibers adhering to the fabric cutting roller.

[0025] The working principle and beneficial effects of the technical solution of this invention are as follows:

[0026] 1. The filter press device in this invention is configured such that the L-shaped plate, U-shaped feed plate, semi-arc plate, drive device 1, roller, semi-arc collection tank, and square shell cooperate with the discharge pipe. The roller in the semi-arc plate rotates forward and crushes the waste textile in the U-shaped feed plate, squeezing out the water contained in the waste textile. This prevents the multi-stage crushing equipment for industrial waste textile from being ineffective in decomposing waste textile containing water. Furthermore, the semi-arc collection tank collects the water, which continues to flow downward into the square shell. The water in the square shell flows downward into the discharge pipe, which discharges the waste textile wastewater. This prevents the wastewater from accumulating due to the inconvenience of the multi-stage crushing equipment for industrial waste textile.

[0027] 2. The cutting device in this invention is designed so that the shaped plate, driving device II, rotating rod, annular block, blade, L-shaped rod, and U-shaped long plate work together with the rubber sheet. The rotating rod drives the annular block to rotate clockwise, and the annular block drives the blade to rotate clockwise. The clockwise rotation of the blade cuts larger waste textiles, preventing the large waste textiles from being difficult to decompose in the multi-stage industrial waste textile crushing equipment. Furthermore, the U-shaped long plate drives the rubber sheet to rotate clockwise. When the blade rotates clockwise to cut larger waste textiles, the rubber sheet prevents the larger waste textiles from falling downwards, preventing poor decomposition effect when the multi-stage industrial waste textile crushing equipment cuts larger waste textiles.

[0028] 3. The distribution device in this invention allows the cylinder, inclined rod, ring, spring plate, L-shaped support rod, and grooved vertical block to work in conjunction with the chamfering plate. Under the elastic force of the spring plate, the spring plate lifts up the initially shredded waste textiles, allowing the initially shredded waste textiles to fall evenly downwards. This prevents the initially shredded waste textiles in the multi-stage industrial waste textile crushing equipment from falling downwards haphazardly. Furthermore, the chamfering plate rotates clockwise to scrape off the wool threads attached to the crushing shell, preventing the wool threads from adhering to the equipment and causing inconvenience in cutting.

[0029] 4. The fabric grinding device in this invention allows the square box, drive device three, cutting roller, inclined plate, long strip clamping rod, and arc-shaped spring sheet to work in conjunction with the scraper. The relative rotation of the cutting roller crushes the initially shredded waste textiles, while the inclined plate restricts the initially shredded waste textiles onto the cutting roller, preventing the multi-stage industrial waste textile crushing equipment from being unable to decompose smaller particles and thus resulting in poor decomposition effect. Furthermore, the arc-shaped spring sheet supports the scraper, which scrapes off the fibers adhering to the cutting roller, preventing the multi-stage industrial waste textile crushing equipment from being damaged by the fibers of the waste textiles.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1-4 As shown in the figure, this embodiment proposes a multi-stage crushing device for industrial waste textiles used in the production of alternative fuel RDF, including a housing 1 and a crushing cylindrical shell 2. The crushing cylindrical shell 2 is inserted through and fixed in the middle of the top surface of the housing 1. It also includes a filter press 3, which is located in the middle of the left side of the housing 1. The filter press 3 includes an L-shaped plate 31, a U-shaped feed plate 32, two semi-arc plates 33, a drive device 34, and a pressing roller 35. The L-shaped plate 31 is fixed in the middle of the left side of the housing 1. The U-shaped feed plate 32 is fixed on the top surface of the L-shaped plate 31 and is inclined on the L-shaped plate 31. The L-shaped plate 31 supports the U-shaped feed plate 32. The two semi-arc plates 33 are respectively fixed on the top surface of the U-shaped feed plate 32. The drive device 34 includes a retainer. The protective shell and motor are fixed to the back of the semi-arc plate 33, and the motor is fixed to the front of the inner wall of the protective shell. The motor shaft runs through and is rotatably mounted on the back of the semi-arc plate 33. The crushing roller 35 is fixed to the front of the motor shaft of the drive device 34. The motor shaft in the drive device 34 drives the crushing roller 35 to rotate forward. The crushing roller 35 is rotatably positioned between the two semi-arc plates 33. The liquid outlet of the U-shaped feed plate 32 is opened on the bottom surface of the U-shaped feed plate 32. The crushing roller 35 in the semi-arc plate 33 rotates forward and crushes the waste textile in the U-shaped feed plate 32. The crushed waste textile enters the crushing round shell 2 in the machine casing 1, so that the crushing roller 35 squeezes out the water contained in the waste textile, thereby avoiding the poor decomposition effect of industrial waste textile multi-stage crushing equipment on waste textile containing moisture.

[0045] The filter press 3 also includes a semi-arc collecting tank 36, a square shell 37, and an outlet pipe 38. The semi-arc collecting tank 36 is fixed to the bottom surface of the U-shaped feed plate 32 and is located at the bottom surface of the outlet of the U-shaped feed plate 32. The water from the crushed waste textiles flows downwards into the outlet of the U-shaped feed plate 32. The filter screen in the outlet of the U-shaped feed plate 32 filters the water into the semi-arc collecting tank 36. The square shell 37 is fixed in the middle of the bottom surface of the semi-arc collecting tank 36. The outlet pipe 38 passes through and is fixed in the middle of the bottom surface of the square shell 37. The semi-arc collecting tank 36 collects water, which continues to flow downwards into the square shell 37. The water in the square shell 37 flows downwards into the outlet pipe 38, which discharges the waste textiles as wastewater. This avoids the inconvenience of wastewater discharge from multi-stage crushing equipment for industrial waste textiles, which can lead to wastewater accumulation.

[0046] The feed hopper of the crushing shell 2 is fixed on the top surface of the crushing shell 2. The U-shaped feed plate 32 is inclinedly arranged on the inner wall of the feed hopper of the crushing shell 2. A filter screen is installed in the liquid outlet of the U-shaped feed plate 32. The liquid outlet of the U-shaped feed plate 32 is located below the crushing roller 35.

[0047] In this embodiment, the worker places waste textiles into the U-shaped feed plate 32. The L-shaped plate 31 supports the U-shaped feed plate 32, and the waste textiles in the U-shaped feed plate 32 move downwards. Then, the drive device 2 42 is started by wire. The motor shaft in the drive device 2 42 starts to rotate forward. The motor shaft in the drive device 1 34 drives the crushing roller 35 to rotate forward. The crushing roller 35 in the semi-arc plate 33 rotates forward, and the crushing roller 35 crushes the waste textiles in the U-shaped feed plate 32. The crushed waste textiles enter the crushing shell 2 in the machine housing 1, so that the crushing roller 35 squeezes out the water contained in the waste textiles, preventing the water contained in the waste textiles from hindering decomposition, thereby avoiding excessive industrial waste textiles. To address the issue of ineffective decomposition of waste textiles containing moisture by multi-stage crushing equipment, this system addresses the problem of water accumulation caused by the inconvenience of waste textile waste discharge due to the crushing roller 35 crushing the waste textiles in the U-shaped feed plate 32. Simultaneously, the water from the crushed waste textiles flows downwards to the outlet of the U-shaped feed plate 32. A filter screen in the outlet of the U-shaped feed plate 32 filters the water into a semi-circular collection tank 36, which collects the water. The water then continues to flow downwards into a square shell 37, and from the square shell 37, it flows downwards into an outlet pipe 38, which discharges the waste textile wastewater. This system prevents inconvenience in treating the crushed waste textile wastewater and avoids the problem of wastewater accumulation caused by the inconvenience of discharging waste textile wastewater in multi-stage industrial waste textile crushing equipment.

[0048] Example 2

[0049] like Figures 5-6As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a cutting device 4. The cutting device 4 is located in the middle of the back of the housing 1. The cutting device 4 includes a forming plate 41, a second driving device 42, a rotating rod 43, several annular blocks 44, and four blades 45. The forming plate 41 is fixed in the middle of the back of the housing 1. The second driving device 42 includes a protective shell and a motor. The motor is fixedly installed inside the top of the protective shell. The rotating rod of the second driving device 42 is inserted through and rotatably mounted on the top surface of the forming plate 41. The forming plate 41 supports the second driving device 42. The rotating rod 43 is fixed to the bottom surface of the rotating rod of the second driving device 42. The rotating rod 43 is located in the middle of the crushing shell 2. The motor shaft of the second drive device 42 drives the rotating rod 43 to rotate clockwise. Several annular blocks 44 are fixed on the outer wall of the rotating rod 43. The annular blocks 44 are staggered on the rotating rod 43. The rotating rod 43 drives the annular blocks 44 to rotate clockwise. The four through holes of the annular blocks 44 are respectively opened on the bottom surface of the annular blocks 44. Four blades 45 are respectively fixed on the outer wall of the annular blocks 44. The annular blocks 44 drive the blades 45 to rotate clockwise. The clockwise rotation of the blades 45 cuts larger waste textiles, thereby avoiding the difficulty of decomposing larger waste textiles in multi-stage industrial waste textile crushing equipment.

[0050] The cutting device 4 also includes four L-shaped rods 46, four U-shaped long plates 47, and four rubber sheets 48. The four L-shaped rods 46 are respectively fixed on the inner walls of the four through holes of several annular blocks 44. The annular blocks 44 drive the L-shaped rods 46 to rotate clockwise. The four U-shaped long plates 47 are respectively fixed on the top surface of the four L-shaped rods 46. The L-shaped rods 46 drive the U-shaped long plates 47 to rotate clockwise. The four rubber sheets 48 are respectively fixed on the inner walls of the four U-shaped long plates 47. The U-shaped long plates 47 drive the rubber sheets 48 to rotate clockwise. When the blade 45 rotates clockwise to cut larger waste textiles, the rubber sheets 48 prevent the larger waste textiles from falling downwards, thereby avoiding poor decomposition effect when the multi-stage crushing equipment for industrial waste textiles cuts larger waste textiles.

[0051] In this embodiment, when the crushed waste textiles enter the crushing cylinder 2 inside the housing 1, the shaping plate 41 supports the drive device 42. The operator starts the motor in the drive device 42 via an electrical wire. The motor shaft of the drive device 42 begins to rotate clockwise, driving the rotating rod 43 to rotate clockwise. The rotating rod 43 drives the annular block 44 to rotate clockwise, which in turn drives the blade 45 to rotate clockwise. The rotating blade 45 shreds larger waste textiles, preventing them from being difficult to decompose and thus avoiding excessive industrial waste textile waste. To address the problem of difficulty in decomposing larger waste textiles in multi-stage crushing equipment, the rotating rod 43 drives the annular block 44 to rotate forward, which in turn drives the L-shaped rod 46 to rotate forward. The L-shaped rod 46 then drives the U-shaped long plate 47 to rotate forward, which in turn drives the rubber sheet 48 to rotate forward. When the blade 45 rotates forward to cut larger waste textiles, the rubber sheet 48 prevents the larger waste textiles from falling downwards, thus avoiding the problem of poor decomposition effect when cutting larger waste textiles in multi-stage industrial waste textile crushing equipment.

[0052] Example 3

[0053] like Figures 6-10 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a distribution device 5 and a cloth-rolling device 6. The distribution device 5 is disposed on the bottom surface of the cutting device 4. The distribution device 5 includes a cylinder 51, four inclined rods 52, a ring 53, and several spring plates 54. The cylinder 51 is fixed to the bottom surface of the rotating rod 43, and the rotating rod 43 drives the cylinder 51 to rotate clockwise. The four inclined rods 52 are respectively fixed to the bottom of the outer wall of the cylinder 51, and the cylinder 51 drives the inclined rods 52 to rotate clockwise. The ring 53 is fixed to the four inclined rods. At the bottom of ring 52, the inclined rod 52 drives the ring 53 to rotate clockwise. Several spring plates 54 are fixed on the inner wall of the ring 53. The ring 53 drives the spring plates 54 to rotate clockwise. The pre-shredded waste textiles fall onto the spring plates 54 on the ring 53. Under the action of the elastic force of the spring plates 54, the spring plates 54 bounce up the pre-shredded waste textiles, allowing the pre-shredded waste textiles to fall evenly downwards, thereby avoiding the pre-shredded waste textiles in the multi-stage industrial waste textile crushing equipment from falling downwards in a mess.

[0054] The distribution device 5 also includes four L-shaped support rods 55, four grooved vertical blocks 56, and four chamfered pieces 57. The four L-shaped support rods 55 are respectively fixed in the middle of the top surface of the four inclined rods 52. The inclined rods 52 drive the L-shaped support rods 55 to rotate clockwise. The four grooved vertical blocks 56 are respectively fixed on the front of the four L-shaped support rods 55. The L-shaped support rods 55 drive the grooved vertical blocks 56 to rotate clockwise. The four chamfered pieces 57 are respectively fixed on the inner wall of the groove of the four grooved vertical blocks 56. The grooved vertical blocks 56 drive the chamfered pieces 57 to rotate clockwise. The four chamfered pieces 57 are respectively rotatably set at the bottom of the inner wall of the crushing shell 2. The chamfered pieces 57 scrape off the waste textile yarn attached to the crushing shell 2 when rotating clockwise, thereby avoiding the inconvenience of cutting caused by the attachment of yarn in the multi-stage crushing equipment for industrial waste textiles.

[0055] The fabric grinding device 6 is located on the bottom surface of the machine casing 1. The fabric grinding device 6 includes a square box 61, a drive unit 62, two cutting rollers 63, and two inclined plates 64. The square box 61 is fixed to the bottom surface of the machine casing 1. The drive unit 62 includes a protective shell and a dual-axis motor. The dual-axis motor is fixedly installed inside the protective shell on the front side. The two shafts of the dual-axis motor of the drive unit 62 pass through and are rotatably mounted on the back side of the square box 61. The square box 61 supports the drive unit 62. The two cutting rollers 63 are respectively fixed to the front sides of the two shafts of the dual-axis motor. The dual-axis motor in the drive unit 62... The rotating shaft drives the cutting rollers 63 to rotate relative to each other. Two inclined plates 64 are fixed to the front and back of the inner wall of the square box 61 respectively. A discharge port is opened at the bottom right side of the square box 61. The two cutting rollers 63 mesh with each other on their opposite surfaces. The two inclined plates 64 are respectively set on the top surfaces of the two cutting rollers 63. The opposite surfaces of the two inclined plates 64 are set as a sliding surface. The relative rotation of the cutting rollers 63 crushes the initially shredded waste textiles. The inclined plates 64 restrict the initially shredded waste textiles to the cutting rollers 63, thereby avoiding the inconvenience of decomposing small particles in multi-stage industrial waste textile crushing equipment, which would result in poor decomposition effect.

[0056] The fabric crushing device 6 also includes two long strip clamps 65, two arc-shaped spring pieces 66, and two scraper blades 67. The two long strip clamps 65 are respectively fixed to the back of two inclined plates 64, which support the long strip clamps 65. The back of the two long strip clamps 65 is provided with a groove in the middle. The two arc-shaped spring pieces 66 are respectively fixed to the inner wall of the groove of the two long strip clamps 65, which support the arc-shaped spring pieces 66. The two scraper blades 67 are respectively fixed to the ends of the two arc-shaped spring pieces 66 away from the two long strip clamps 65, which support the scraper blades 67. The two scraper blades 67 are respectively set on the outer wall of the two cutting rollers 63. The scraper blades 67 scrape off the fibers adhering to the cutting rollers 63, thereby avoiding damage to the multi-stage crushing equipment of industrial waste textiles caused by the fibers of waste textiles entangled in the equipment.

[0057] In this embodiment, while the motor shaft of the second drive device 42 drives the rotating rod 43 to rotate clockwise, the rotating rod 43 drives the cylinder 51 to rotate clockwise, the cylinder 51 drives the inclined rod 52 to rotate clockwise, the inclined rod 52 drives the ring 53 to rotate clockwise, and the ring 53 drives the spring plate 54 to rotate clockwise. The initially shredded waste textiles fall onto the spring plate 54 on the ring 53. Under the action of the elastic force of the spring plate 54, the spring plate 54 bounces up the initially shredded waste textiles, allowing the initially shredded waste textiles to fall evenly downwards, preventing the initially shredded waste textiles from piling up haphazardly. This avoids the problem of the initially shredded waste textiles falling haphazardly downwards in multi-stage industrial waste textile crushing equipment. While the cylinder 51 drives the inclined rod 52 to rotate forward, the inclined rod 52 drives the L-shaped support rod 55 to rotate forward, the L-shaped support rod 55 drives the grooved vertical block 56 to rotate forward, and the grooved vertical block 56 drives the chamfering plate 57 to rotate forward. The chamfering plate 57 scrapes off the waste textile yarn attached to the crushing shell 2, preventing the waste textile yarn from adhering to the crushing shell 2, thus avoiding the problem of yarn adhesion causing inconvenience in cutting the equipment in multi-stage industrial waste textile crushing equipment.

[0058] When the waste textiles need further decomposition, the square box 61 supports the drive unit 62. The operator starts the dual-axis motor shaft in the drive unit 62 via an electrical wire. The dual-axis motor shaft in the drive unit 62 begins to rotate relative to each other, driving the cutting roller 63 to rotate relative to each other. The relative rotation of the cutting roller 63 crushes and grinds the initially shredded waste textiles. The inclined plate 64 restricts the initially shredded waste textiles onto the cutting roller 63, preventing the waste textiles from decomposing into smaller particles or fibers, thus... This design avoids the problem of poor decomposition effect caused by the inconvenience of decomposing small particles in multi-stage industrial waste textile crushing equipment. While the inclined plate 64 restricts the initially shredded waste textiles to the cutting roller 63, the inclined plate 64 supports the long strip clamp 65, the long strip clamp 65 supports the arc-shaped spring 66, and the arc-shaped spring 66 supports the scraper 67. The scraper 67 scrapes off the fibers adhering to the cutting roller 63, preventing the fibers of the waste textiles from getting tangled on the cutting roller 63. This avoids the problem of the multi-stage industrial waste textile crushing equipment being damaged by the fibers of the waste textiles getting tangled.

[0059] Example 4

[0060] A crushing process, employing the aforementioned multi-stage crushing equipment for industrial waste textiles used in RDF (Reactive Fuel Dioxide) production, includes the following steps:

[0061] S1. The roller in the semi-arc plate rotates forward, and the roller crushes the waste textile in the U-shaped feed plate.

[0062] S2. The semi-circular liquid collection tank collects water, which continues to flow downwards into the square shell. The water in the square shell flows downwards into the liquid outlet pipe, which discharges the waste textile wastewater.

[0063] S3. The ring block drives the blade to rotate forward, and the forward rotation of the blade will cut larger waste textiles into shreds.

[0064] S4. The U-shaped long plate drives the rubber sheet to rotate in the forward direction, and the rubber sheet prevents larger waste textiles from falling downwards.

[0065] S5. The diagonal bar drives the ring to rotate clockwise, and the ring drives the spring plate to rotate clockwise. The initially shredded waste textiles fall onto the spring plate on the ring.

[0066] S6. The grooved vertical block drives the chamfering plate to rotate clockwise, and the clockwise rotation of the chamfering plate scrapes off the waste textile yarn attached to the broken round shell.

[0067] S7. The relative rotation of the cutting rollers crushes and squeezes the initially shredded waste textiles, while the inclined plate restricts the initially shredded waste textiles onto the cutting rollers.

[0068] S8. The scraper blade removes the fibers adhering to the fabric cutting roller.

[0069] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
