Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, and in particular to a device for recycling waste materials from the preparation of amino membrane plastics. Background Technology

[0002] With increasing global emphasis on environmental protection and resource recycling, the effective recycling and reuse of plastic waste has become an important research and development direction. This is especially true for high-performance materials like amino membrane plastics, which are widely used in packaging, construction, and electronics industries. If these materials are not properly disposed of after disposal, they not only waste resources but may also cause serious environmental pollution. Therefore, developing efficient and environmentally friendly plastic waste recycling equipment is of significant practical importance.

[0003] Patent application number CN201610241754.5 discloses a plastic crushing device, including a cylinder with a pair of crushing rollers at the bottom and two inclined baffles at the top opening. Plastic items are fed into the cylinder through the center of the two baffles, and the plastic items continuously fall into the crushing rollers. The upper plastic items prevent the smoother, rounder plastic items below from popping out of the cylinder, and the baffles prevent plastic fragments from flying everywhere.

[0004] The aforementioned devices can often only perform rough cutting or crushing, making it difficult to meet the requirements of fine processing, especially since they are not flexible enough in adjusting to the needs of particles of different sizes; particles that do not meet the standards after screening need to be stopped for cleaning, resulting in reduced efficiency. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a waste recycling device for the preparation of amino membrane plastics, so as to solve the problems that existing plastic crushing devices cannot be adjusted to meet the needs of particles of different sizes and that particles that do not meet the standards after screening need to be stopped for cleaning.

[0006] To achieve the above objectives, the present invention provides a waste recycling device for the preparation of amino membrane plastics, comprising a crushing cylinder, the bottom of which is connected to a discharge cylinder, the bottom of which is connected to an extrusion cylinder for conveying material, and further comprising:

[0007] At least one set of fixed blades is fixed to the inner wall of the feed cylinder;

[0008] The moving blades are one-to-one corresponding to the fixed blades and fixedly sleeved on the same shaft. The shaft is slidably disposed with the bottom of the extrusion cylinder, and the bottom of the extrusion cylinder is provided with a power assembly for driving the shaft to rotate and move vertically.

[0009] A sieve plate fixedly sleeved on the shaft is used to screen plastic particles that do not meet particle standards.

[0010] A feeding cylinder has an air hole that communicates with the inner cavity of the extrusion cylinder. One side of the bottom of the feeding cylinder is connected to a slag discharge pipe, and the other side is connected to a return pipe, which are respectively connected to the slag discharge hole and the return hole opened on the crushing cylinder.

[0011] The sealed side plate fixed to the bottom of the screen plate frame and the sealed bottom plate at the bottom of the frame can be used to seal the slag discharge hole and the material discharge cylinder, respectively.

[0012] A suction pump installed on the extrusion cylinder is used to create negative pressure.

[0013] Furthermore, it also includes a feed cylinder located at the top of and connected to the crushing cylinder. The top of the feed cylinder is provided with a feed hopper, and the inner cavity of the feed cylinder is rotatably equipped with two sets of independent power sources driving mirror-rotating crushing rollers for coarse crushing of plastic.

[0014] Furthermore, the power assembly includes an end block fixed to the bottom of the shaft, and a vertical power component and a rotary power component for driving the end block to move vertically and rotate.

[0015] Furthermore, the vertical power component includes a connecting plate rotatably sleeved on the bottom end of the end block, the connecting plate being connected to an electric telescopic rod, and the electric telescopic rod being fixed to the bottom of the crushing cylinder.

[0016] Furthermore, the rotating power component includes a rack disposed on the outer periphery of the end block, and a power motor fixed on the crushing cylinder. The output end of the power motor is connected to a drive gear and an intermediate gear located between the end block and the drive gear. The three mesh with each other, and the intermediate gear is rotatably disposed at the bottom of the crushing cylinder.

[0017] Furthermore, a vertical conveying auger is rotatably installed inside the feeding cylinder, and an auger motor for driving the vertical conveying auger to rotate is installed at the top of the feeding cylinder.

[0018] Furthermore, the extrusion cylinder is arranged at an angle, and a sprayer connected to an external water supply pipe is fitted around the outer periphery of the extrusion cylinder. A spray pipe is installed inside the extrusion cylinder through the inner periphery of the sprayer. The extrusion cylinder is equipped with a fixed drainage cylinder and a centrifugal drainage cylinder, which are connected by a rotating clamp and are equipped with a driving component to rotate the centrifugal drainage cylinder. Water squeezing components are installed inside the fixed drainage cylinder and the centrifugal drainage cylinder. Drainage holes are opened on both the fixed drainage cylinder and the centrifugal drainage cylinder.

[0019] Furthermore, the dewatering assembly includes a dewatering auger, the downward bottom end of which is rotatably connected to the extrusion cylinder. The spacing between the spiral blades on the dewatering auger decreases sequentially in the conveying direction. One end of the extrusion cylinder is equipped with a dewatering motor for driving the auger to rotate.

[0020] Furthermore, the drive assembly includes a drive motor fixed on the extrusion cylinder, a transmission rod connected to the output end of the drive motor, a drive gear connected to the end of the transmission rod, and a driven gear ring that meshes with the drive gear fixedly sleeved on the outer periphery of the centrifugal drainage cylinder.

[0021] Furthermore, it also includes a cutting ring, which is fixed to the end of the centrifugal drain cylinder. At least one set of cutting blades is fixed on the inner wall of the cutting ring. The cutting ring rotates with the centrifugal drain cylinder to cut and disperse the plastic particles that are squeezed and compacted by the squeezing assembly inside the centrifugal drain cylinder.

[0022] The beneficial effects of this invention are as follows: The power assembly drives the shaft to synchronously adjust the gap and rotation speed of the moving and fixed blades, improving the crushing precision and efficiency; the screen plate moves downwards with the shaft, and the closed structure switches the slag discharge path, combined with negative pressure suction to achieve closed-loop return of substandard particles, effectively reducing energy consumption; the gradient variable-pitch spiral blades of the dewatering auger generate progressively stronger compressive force, combined with the high-speed rotation and drying effect of the centrifugal dewatering cylinder, effectively removing internal moisture from the plastic particles; finally, the rotating cutting ring thoroughly breaks up the agglomerated particles, ensuring that the recycled plastic particles are loose and uniform, directly meeting the needs of industrial production.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0037] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a waste recycling device for amino film plastic production includes a crushing cylinder 3, the bottom of which is connected to a discharge cylinder 35, the bottom of which is connected to an extrusion cylinder 1 for conveying materials, and further includes:

[0039] At least one set of fixed blades 31 are fixed to the inner wall of the feed cylinder 4;

[0040] The movable blade 32 is corresponding to the fixed blade 31 and fixedly sleeved on the same shaft 321. The shaft 321 is slidably disposed with the bottom of the extrusion cylinder 1, and the bottom of the extrusion cylinder 1 is provided with a power assembly 34 for driving the shaft 321 to rotate and move vertically.

[0041] The sieve plate 33, which is fixedly sleeved on the shaft 321, is used to screen plastic particles that do not meet the particle standard.

[0042] The feeding cylinder 5 has an air hole 56 that communicates with the inner cavity of the extrusion cylinder 1. A slag discharge pipe 53 is connected to one side of the bottom of the feeding cylinder 5, and a return pipe 52 is connected to the other side. The slag discharge hole 36 and the return hole 37 opened on the crushing cylinder 3 are respectively connected.

[0043] The sealed side plate 331 fixed to the bottom of the frame of the screen plate 33 and the sealed bottom plate 332 at the bottom of the frame can be used to seal the slag discharge hole 36 and the material discharge cylinder 35, respectively.

[0044] A suction pump 7 installed on the extrusion cylinder 1 is used to create negative pressure.

[0045] In this embodiment, the amino film plastic waste to be processed is first fed into the feeding cylinder 4 through the feeding hopper 41. After preliminary crushing, it enters the crushing cylinder 3. Inside the crushing cylinder 3, at least one set of fixed blades 31 are fixed to the inner wall of the cylinder 51, and the corresponding moving blades 32 are fixed on the same shaft 321. They are driven to rotate and move vertically by the power component 34 at the bottom of the extrusion cylinder 1 to achieve further fine crushing of the plastic waste. Specifically, after the material falls into the crushing chamber, it is first violently impacted by the high-speed rotating moving blades 32. The material that is thrown away is flung towards the inner wall of the chamber under the action of centrifugal force, and just enters the narrow gap formed by the moving blades 32 and the fixed blades 31. When the moving blades 32 sweep across the fixed blades 31 at high speed, their cutting edges form a relative misalignment with the cutting edges of the fixed blades 31. According to different particle size requirements, by vertically moving the moving blades 32, the gap between the fixed blades 31 and the moving blades 32 can be automatically reduced, which can increase the shearing strength and directly produce finer particles to meet different usage requirements.

[0046] Large particles that fail to pass through the sieve plate 33 accumulate on the sieve plate 33, while standard plastic particles fall into the extrusion cylinder 1 through the feeding cylinder 35. During this process, the suction pump 7 creates a negative pressure environment through the air hole 56 to promote smooth material conveying. Subsequently, after being washed by the sprayer 6, the plastic particles are squeezed by the water squeezing component 17 to remove excess water. The washed particles enter the centrifugal drain cylinder 12 to quickly throw out the squeezed water. Finally, the cutting blades on the inner wall of the cutting ring 15 break up any possible clumps of plastic to ensure that the final product has a uniform particle size. The treated plastic particles are discharged from the device outlet, ready to be used as recycled resources or directly enter the next round of production.

[0047] In addition, when large particles that fail to pass through the screen plate 33 accumulate on the surface of the screen plate 33, feeding into the crushing cylinder is stopped first. Then, the drive shaft 321 is moved downward by the power component 34, which moves the screen plate 33 and the sealing side plate connected to it downward synchronously until it is below the slag discharge hole 36. At the same time, the sealing bottom plate 332 moves downward and presses against the top of the discharge cylinder 35 to seal the discharge cylinder 35. At this time, the negative pressure formed by the suction pump 7 in the extrusion cylinder 1 acts on the screen plate 33 through the air hole 56, and draws the accumulated large plastic waste particles into the feeding cylinder 5 through the slag discharge hole 36 and the slag discharge pipe 53. After being vertically conveyed in the feeding cylinder 5, the material returns to the top of the crushing cylinder through the return pipe 52 and the return hole 37 and enters the crushing chamber for further crushing.

[0048] The entire process efficiently achieves the effective recycling and reuse of waste plastics, improving resource utilization and reducing environmental pollution.

[0049] Preferably, it also includes a feed cylinder 4 disposed on top of and connected to the crushing cylinder 3. The top of the feed cylinder 4 is provided with a feed hopper 41, and the inner cavity of the feed cylinder 4 is provided with two sets of independent power sources driving mirror rotation of the crushing rollers 42 for coarse crushing of plastic.

[0050] The amino film plastic waste to be processed is fed into the device through the feed hopper 41 located at the top of the feed cylinder 4; after the waste enters the feed cylinder 4, it is subjected to preliminary coarse crushing by two sets of crushing rollers 42; the two crushing rollers 42 rotate in opposite directions, so that the incoming plastic waste is effectively torn and crushed into smaller pieces; the material after preliminary crushing gradually moves downward by gravity and falls into the crushing cylinder 3 through the bottom outlet for further fine crushing.

[0051] This ensures that the material entering the crushing cylinder 3 is of relatively uniform size, which is beneficial to improving the effect of subsequent fine crushing processes and the stability of equipment operation.

[0052] Preferably, the power assembly 34 includes an end block 341 fixed to the bottom of the shaft 321, and a vertical power component and a rotary power component for driving the end block 341 to move vertically and rotate.

[0053] The vertical power component includes a connecting plate 342 rotatably sleeved on the bottom end of the end block 341. The connecting plate 342 is connected to the electric telescopic rod 343, which is fixed to the bottom of the crushing cylinder 3.

[0054] The rotating power component includes a rack 344 disposed on the outer periphery of the end block 341, a power motor 345 fixed on the crushing cylinder 3, a drive gear 346 connected to the output end of the power motor 345, and an intermediate gear 347 located between the end block 341 and the drive gear 346. The three mesh with each other, and the intermediate gear 347 is rotatably disposed at the bottom of the crushing cylinder 3.

[0055] When the position of end block 341 needs to be adjusted, the electric telescopic rod 343 starts to work. One end of the electric telescopic rod 343 is connected to the connecting plate 342, which is rotatably sleeved on the bottom end of end block 341. This allows the telescopic action of the electric telescopic rod 343 to control the vertical displacement of end block 341. At the same time, in order to drive end block 341 to rotate, the power motor 345 on the crushing cylinder 3 starts. The drive gear 346 at its output end meshes with the rack 344 located on the outer periphery of end block 341 through the intermediate gear 347, thereby transmitting rotational power to end block 341 and causing it to rotate at a predetermined speed and direction. Through this structural design, end block 341 can be adjusted vertically under the action of electric telescopic rod 343, thereby adjusting the gap between moving blade 32 and fixed blade 31.

[0056] Preferably, a vertical conveying auger 54 is rotatably installed inside the feeding cylinder 5, and an auger motor 55 for driving the vertical conveying auger 54 to rotate is installed at the top of the feeding cylinder 5.

[0057] The auger can rotate freely around its axis to facilitate the upward conveying of materials; the material located at the bottom of the feeding cylinder 5 is gradually drawn into the space between the auger blades and moves upward along the spiral path formed by the auger blades until it is conveyed to the return pipe 52 of the feeding cylinder 5, thereby realizing the vertical lifting and transmission of the material.

[0058] Preferably, the extrusion cylinder 1 is arranged at an angle, and a sprayer 6 connected to an external water supply pipe is fitted around the outer periphery of the extrusion cylinder 1. A spray pipe 61 is provided on the inner periphery of the sprayer 6 and passes through the inside of the extrusion cylinder 1. The extrusion cylinder 1 is provided with a fixed drainage cylinder 11 and a centrifugal drainage cylinder 12, which are connected by a rotating clamp 13 and a driving component 14 is provided to rotate the centrifugal drainage cylinder 12. A water squeezing component 17 is provided inside the fixed drainage cylinder 11 and the centrifugal drainage cylinder 12. Drainage holes are provided on both the fixed drainage cylinder 11 and the centrifugal drainage cylinder 12.

[0059] In this embodiment, the plastic granules, after being screened by the crushing cylinder 3, enter the inclined extrusion cylinder 1 via the discharge cylinder 35; an external water source continuously supplies water to the spray pipe 61 through the sprayer 6, and the water flows through the spray pipe 61 through the inner wall of the extrusion cylinder 1 to wash the moving plastic granules; the wet granules first enter the fixed drainage cylinder 11, and under the action of the water squeezing auger 172 of the water squeezing assembly 17, they are pushed axially and compressed step by step, during which some water is discharged through the drainage hole of the fixed drainage cylinder 11; then the material enters the centrifugal drainage cylinder 1. 2. At this time, the drive motor 141 of the drive assembly 14 drives the drive gear 143 to rotate through the transmission rod 142, driving the centrifugal drain cylinder 12, which is fixed to the driven gear ring 144, to rotate at high speed. The residual water is removed twice through the drain hole of its pipe wall under the action of centrifugal force. The dehydrated plastic particles are broken up and clumped at the end of the centrifugal drain cylinder 12 by the cutting blade on the inner wall of the cutting ring 15, and the recycled particles are discharged from the outlet. At the same time, the negative pressure generated by the suction pump makes the air in the extrusion cylinder flow continuously, and the flowing air can dry the washed particles.

[0060] Preferably, the dewatering assembly 17 includes a dewatering auger 172, the downward bottom end of which is rotatably connected to the extrusion cylinder 1, the pitch of the spiral blades on the dewatering auger 172 decreases sequentially in the conveying direction, and a dewatering motor 171 for driving the auger to rotate is provided at one end of the extrusion cylinder 1.

[0061] The dewatering motor 171 drives the dewatering auger 172 to rotate around its axis. The downward bottom end of the auger is rotatably connected to the extrusion cylinder 1 through a bearing structure. At this time, the wet plastic granules fed into the discharge cylinder 35 enter the fixed drainage cylinder 11 and move along the axial direction of the inclined extrusion cylinder 1 under the push of the spiral blades of the dewatering auger 172. Since the spacing of the spiral blades gradually decreases from the feed end to the discharge end along the conveying direction of the plastic granules, the material is compressed by increasing force step by step during the conveying process. The material pushed by the wide-spacing blades at the front end of the dewatering auger 172 forms high pressure at the subsequent narrow-spacing blades, forcing water to seep out from the inside of the plastic granules. The squeezed water is continuously discharged through the drainage holes on the wall of the fixed drainage cylinder 11 under pressure.

[0062] Preferably, the drive assembly 14 includes a drive motor 141 fixed on the extrusion cylinder 1, the output end of the drive motor 141 is connected to a transmission rod 142, the end of the transmission rod 142 is connected to a drive gear 143, and a driven gear ring 144 that meshes with the drive gear 143 is fixedly sleeved on the outer periphery of the centrifugal drainage cylinder 12.

[0063] The drive motor 141, fixed to the outer wall of the extrusion cylinder 1, starts, and its output end drives the transmission rod 142 to rotate in the same direction. The drive gear 143 mounted at the end of the transmission rod 142 then meshes with the driven gear ring 144 fixed on the outer periphery of the centrifugal drainage cylinder 12, and the torque is transmitted to the centrifugal drainage cylinder 12 through the gear pair. Under the continuous action of the drive assembly 14, the centrifugal drainage cylinder 12 rotates around its axis, and the residual water is efficiently thrown out through the drainage holes in the cylinder wall.

[0064] The rotating clamp 13 includes a clamp body fixed to the outer periphery of the end of the fixed drain cylinder 11. A clamp ring 131 is provided on the inner periphery of the clamp body. An annular groove that slides with the clamp ring 131 is provided on the outer periphery of the centrifugal drain cylinder 12. The rotating clamp 13 maintains a sealed rotational connection between the fixed drain cylinder 11 and the centrifugal drain cylinder 12, ensuring a continuous and stable dehydration process.

[0065] Preferably, it also includes a cutting ring 15, which is fixed to the end of the centrifugal drain cylinder 12. At least one set of cutting blades is fixed on the inner wall of the cutting ring 15. The cutting ring 15 rotates with the centrifugal drain cylinder 12 to cut and disperse the plastic particles that are squeezed and compacted by the squeezing assembly 17 inside the centrifugal drain cylinder 12.

[0066] When the plastic granules are dehydrated by the centrifugal drain cylinder 12 and transported to its end outlet, the cutting ring 15 fixed at the end of the centrifugal drain cylinder 12 rotates synchronously with the cylinder body. At least one set of cutting blades fixed on its inner wall cuts and beats the passing plastic granules during the rotation, breaking up and dispersing the plastic granules that have clumped together due to the squeezing component 17.

[0067] In use, amino film plastic waste is fed into the feed hopper 41 and is initially crushed by two sets of mirror-rotating crushing rollers 42 inside the feed cylinder 4; then the material falls into the crushing cylinder 3; the electric telescopic rod 343 of the power assembly 34 can drive the connecting plate 342 to drive the shaft 321 to move vertically according to the crushing particle size requirements, so that the gap between the moving blade 32 fixed to the shaft and the fixed blade 31 on the cylinder wall is adjustable; the power motor 345 drives the rack 344 on the outer periphery of the end block 341 through the meshing of the drive gear 346 and the intermediate gear 347, so that the moving blade 32 rotates and cooperates with the fixed blade 31 to form high-speed shearing; after crushing, the material is classified by the screen plate 33, and the qualified particles pass through the screen plate and enter the inclined extrusion cylinder 1 through the discharge cylinder 35; when the unqualified particles accumulate, the shaft 321 moves down to block the discharge cylinder 35 and seal the bottom plate of the screen plate 33 connected to the sealed side plate 331. 332 opens the slag discharge hole 36, and the suction pump 7 forms a negative pressure through the air hole 56, drawing the accumulated material into the feeding cylinder 5 through the slag discharge pipe 53. The vertical conveying auger 54 driven by the auger motor 55 lifts the material to the return hole 37 for further crushing. After the particles entering the extrusion cylinder 1 are washed by the spray pipe 61 of the sprayer 6, the water squeezing motor 171 drives the water squeezing auger 172 to rotate, squeezing the particles and reducing their moisture content. The water is discharged through the drain hole. Then the material enters the centrifugal drainage cylinder 12. The drive motor 141 meshes with the driven gear ring 144 through the drive gear 143 at the end of the transmission rod 142, driving the centrifugal drainage cylinder to rotate and generate centrifugal force, further reducing the moisture content of the particles. The residual water is removed through the drain hole in the cylinder wall. Finally, the dehydrated particles are cut and broken up by the linear cutting blade on the inner wall of the cutting ring 15, outputting recycled plastic particles with uniform particle size.
