Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and more specifically, to a modified plastic crushing and sieving device. Background Art

[0002] In the field of waste recycling, plastic waste can be used as the basic raw material for modified plastics after being crushed, washed, sieved, and melted and regenerated. These recycled plastics are modified by adding various modifiers such as reinforcing agents, plasticizers, flame retardants, etc. to endow them with specific properties and uses. In this way, plastic waste becomes a low-cost raw material for producing modified plastics through recycling and reuse.

[0003] In the existing recycling and crushing and sieving treatment of plastics or waste containing plastics, plastic waste is usually directly sieved according to particle size after being crushed, making it difficult to efficiently separate light and heavy plastic fragments, resulting in the mixing of plastic particles with different densities, reducing the sorting purity, and also affecting the efficiency of subsequent processing, and unable to ensure efficient resource recovery and recycling.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to the attached drawings of the specification Figures 1-9 , a modified plastic crushing and sieving device according to an embodiment of the present invention is as Figure 1 shown, which includes a water washing and crushing mechanism 1. A floating separation and sieving mechanism 2 is fixedly installed at the bottom of the water washing and crushing mechanism 1. A water circulation treatment mechanism 3 is communicated and arranged at the bottom of the floating separation and sieving mechanism 2;

[0035] Referring to Figure 3 and Figure 5 shown, the floating separation and sieving mechanism 2 includes a first soaking cylinder 21. An inclined first guide table 22 and a second guide table 23 are respectively communicated and arranged on the outer wall of the first soaking cylinder 21. Two guide auxiliary cylinders 24 respectively connected to the first guide table 22 and the second guide table 23 are fixedly installed on the inner wall of the first soaking cylinder 21. Among them, the two guide auxiliary cylinders 24 are arranged in a parallel state, and the guide auxiliary cylinder 24 connected to the first guide table 22 is arranged at the top of the guide auxiliary cylinder 24 connected to the second guide table 23. In actual use, the inner cavity of the first soaking cylinder 21 is filled with flowing water, and the combined water flows out through the first guide table 22 and the second guide table 23, so that the height of the water is kept flush with the horizontal center line of the guide auxiliary cylinder 24 connected to the first guide table 22, and the guide auxiliary cylinder 24 connected to the second guide table 23 is attached to the bottom of the first soaking cylinder 21. The purpose of such a setting is that when the plastic or waste particles containing plastic after being crushed by the water washing and crushing mechanism 1 fall into the inner cavity of the first soaking cylinder 21, the light particles float on the water surface, and the heavy particles sink to the bottom. There is a height difference between the first guide table 22 and the second guide table 23, which is used to ensure that the particles have enough time for separation, and then more pure materials can be separated, which helps to improve the purity and quality of the recycled plastic;

[0036] At the same time, referring to Figure 4 and Figure 6As shown in the figure, a limiting frame 25 is fixedly installed in the inner cavity of each of the two material guiding auxiliary cylinders 24. A sliding rod 26 arranged horizontally is slidably installed in the inner cavity of the limiting frame 25. A first filter plate 210 slidably connected to the material guiding auxiliary cylinder 24 is fixedly installed on the outer wall of the sliding rod 26. One side of the first filter plate 210 is fixedly connected to a threaded lead screw 27. One end of the threaded lead screw 27 is fixedly connected to an adapter frame 28. Scrapers 29 are rotatably connected to both sides of the adapter frame 28. A power assembly for driving the threaded lead screw 27 to translate is engaged with the outer wall of the threaded lead screw 27. Among them, a limiting sliding groove is provided between the first filter plate 210 and the material guiding auxiliary cylinder 24, so that the first filter plate 210 maintains a translational motion state in the inner cavity of the material guiding auxiliary cylinder 24 and does not rotate. Moreover, in the normal state, the sliding rod 26 drives the first filter plate 210 to block the side of the material guiding auxiliary cylinder 24 away from the inner wall of the first soaking cylinder 21. The threaded lead screw 27 extends out of the inner cavity of the material guiding auxiliary cylinder 24 as a whole. When the power assembly is activated to cause the threaded lead screw 27 to translate in the direction of the inner cavity of the material guiding auxiliary cylinder 24, the adapter frame 28 can be gradually driven to pull the scraper 29 to move towards the material guiding auxiliary cylinder 24. Then, the light debris floating on the water surface and the heavy debris deposited at the bottom of the first soaking cylinder 21 are scraped by the displacement of the scraper 29 and move towards the inner cavity of the corresponding material guiding auxiliary cylinder 24. During the movement, the light debris floating on the water surface and the heavy debris deposited at the bottom of the first soaking cylinder 21 are respectively scraped into the inner cavity of the material guiding auxiliary cylinder 24 and come into contact with the first filter plate 210 for filtration, so as to discharge debris of different densities along with the water flow through the first material guiding table 22 and the second material guiding table 23 to the outside and enter the next device. In the plastic recycling process, uniform plastic debris can be obtained, reducing the complexity in subsequent processes such as melting, extrusion, or molding, and reducing the scrap rate and the loss of processing equipment.

[0037] Further, referring to Figure 6As shown in the figure, the power assembly includes a support plate 211 fixedly installed on the outer wall of the material guiding auxiliary cylinder 24. An internally threaded sleeve 212 that is rotationally installed inside the support plate 211 and is threadedly connected to the threaded screw rod 27. A first external gear plate 213 is fixedly installed on one side of the internally threaded sleeve 212 close to the first filter plate 210. During actual use, by driving the first external gear plate 213 to rotate, the internally threaded sleeve 212 can be rotated on the outer wall of the threaded screw rod 27, and then the threaded screw rod 27 is driven to perform a linear horizontal displacement movement in its inner cavity, thereby synchronously driving the first filter plate 210 to reciprocate along with the sliding rod 26 in the inner cavity of the material guiding auxiliary cylinder 24. When the first filter plate 210 moves towards the limiting frame 25, it can be used to assist in guiding the water flow and plastic particles in the water into the inner cavity of the material guiding auxiliary cylinder 24. After the qualified particles are screened and discharged through the first filter plate 210, the unqualified particles remain on one side of the first filter plate 210. At this time, combined with the movement recovery of the first filter plate 210 and the sliding rod 26, the unqualified particles are pushed into the water again;

[0038] At the same time, combined with Figures 3-4 As shown in the figure, an electric rotating rod 216 rotatably connected to the first soaking cylinder 21 is provided between the two material guiding auxiliary cylinders 24. Two second external gear plates 215 respectively meshing with the first external gear plate 213 are fixedly installed on the outer wall of the electric rotating rod 216. During actual use, by starting the rotation of the electric rotating rod 216, the second external gear plates 215 can be synchronously driven to rotate through the second external gear plates 215, and then the first external gear plate 213 is driven to rotate to drive the threaded screw rod 27, the connecting frame 28 and the scraping plate 29 to move as a whole in the inner cavity of the first soaking cylinder 21 for scraping and discharging plastic particles. Among them, the outer circumferential diameter length of the first filter plate 210 is the same as the inner circumferential diameter length of the material guiding auxiliary cylinder 24. The purpose of this setting is to make there be a certain sealing between the first filter plate 210 and the material guiding auxiliary cylinder 24, so that during the movement, the particles will not seep out from the contact part between the first filter plate 210 and the material guiding auxiliary cylinder 24, thereby improving the accuracy of screening of the first filter plate 210. At the same time, the outer circumferential diameter length of the first external gear plate 213 is greater than the outer circumferential diameter length of the material guiding auxiliary cylinder 24, and a plurality of through slots 214 are provided in a penetrating manner inside the first external gear plate 213. The purpose of this setting is that when the through slots 214 rotate to assist in driving the threaded screw rod 27 to translate, due to the setting of the plurality of through slots 214, it will not affect the problem that the plastic particles in the water pass through and come into contact with the first filter plate 210 for screening.

[0039] As a further expansion of this solution, referring to Figure 3 、 Figure 7 and Figure 9As shown in the figure, the water circulation treatment mechanism 3 includes a second soaking cylinder 31 connected to the bottom of the first soaking cylinder 21. The second soaking cylinder 31 is threadedly connected to the first soaking cylinder 21, and a sealing component is provided at the threaded connection between the second soaking cylinder 31 and the first soaking cylinder 21 to maintain the convenience of disassembly and assembly between the first soaking cylinder 21 and the second soaking cylinder 31 while not affecting the sealing of water flow. At the same time, a plurality of second filter plates 32 are fixedly installed on the inner wall of the second soaking cylinder 31. A first drain pipe 33 is connected to the bottom of the second soaking cylinder 31. In actual use, the top of the second filter plate 32 at the top layer of the inner wall of the second soaking cylinder 31 is flush with the bottom of the first filter plate 210 to allow the precipitated heavy plastic fragments to be placed on the top of the second filter plate 32. Among them, the first drain pipe 33 is provided for discharging the wastewater. By making the first soaking cylinder 21 and the second soaking cylinder 31 easy to disassemble, the treated wastewater can be conveniently discharged after the work is completed;

[0040] Among them, the aperture sizes of the meshes set inside the plurality of second filter plates 32 are different, and the aperture sizes of the meshes set inside the plurality of second filter plates 32 are arranged in a decreasing order from top to bottom to filter out impurity particles of different sizes layer by layer. In use, after the sewage soaked with plastic fragments passes through multiple second filter plates 32, the water flow filters out large-particle impurities, such as larger plastic fragments or solid impurities, through the second filter plate 32 with a coarse mesh hole at the top. Then, the water flow further removes smaller particles through the middle fine mesh hole. Finally, the water enters the second filter plate 32 at the lowest position to completely filter out tiny particles, suspended substances, and other residual impurities, and then the filtered water is discharged outward through the first drain pipe 33. At the same time, one end of the first drain pipe 33 is threadedly connected to a second drain pipe 34, and one end of the second drain pipe 34 is connected to a water storage bucket 35. A first water pump 36 is fixedly installed at the connection between the second drain pipe 34 and the water storage bucket 35, and the discharged water is stored in the water storage bucket 35 through the first water pump 36 for use in cleaning plastics or plastic-containing waste materials next time.

[0041] As a further expansion of this solution, refer to Figure 3 and Figures 7-8 As shown in the figure, the water washing and crushing mechanism 1 includes a crushing cylinder 101 arranged on the top of the first soaking cylinder 21. The outer wall of the crushing cylinder 101 is fixedly installed with a support frame 102. The support frame 102 surrounds the outer periphery of the first soaking cylinder 21 and the second soaking cylinder 31 and is fixedly connected to the first soaking cylinder 21;

[0042] The top and bottom of the crushing cylinder 101 are both open, and the crushing cylinder 101 is in a communicating state with the first soaking cylinder 21. A hollow partition plate 103 is fixedly installed at the bottom of the crushing cylinder 101, and a double-layer crushing blade 104 is rotatably installed on the top of the hollow partition plate 103. A plurality of directional fixed blades 105 are fixedly installed on the inner wall of the crushing cylinder 101 at equal intervals in a circular pattern. During actual use, by starting the double-layer crushing blade 104, plastics or waste materials containing plastics are crushed in the inner cavity of the crushing cylinder 101. During the process of the plastic waste contacting the inner wall of the directional fixed blade 105, crushing treatment is carried out again. The purpose of this setting is that, compared with only using traditional rotary blades, it has higher cutting efficiency and more uniform particle size. The shear force generated when the double-layer crushing blade 104 and the directional fixed blade 105 work together reduces the cutting resistance, can quickly cut the plastic waste into pieces, avoid excessive wear of the blades, and can precisely control the size of the plastic particles, making the particles more uniform. In addition, the shear effect can effectively improve the stability during the cutting process, reduce energy consumption, and improve the overall crushing efficiency;

[0043] Among them, a first water guide pipe 106 is fixedly installed on the inner wall of the crushing cylinder 101. A plurality of spray heads 107 are communicated and arranged on the outer wall of the first water guide pipe 106 at equal intervals in a circular pattern. The outer wall of the first water guide pipe 106 is communicated with a plurality of shunt pipes 108. During actual use, the plurality of shunt pipes 108 are used to disperse and guide external water into the inner cavity of the first water guide pipe 106 and uniformly spray it from the plurality of spray heads 107. During the process of crushing the plastic waste, by continuously spraying water, the plastic particles during crushing are preliminarily rinsed to remove impurities such as dust and dirt. And as the water naturally falls through the hollow partition plate 103, the qualified plastic fragments are directly dropped into the inner cavity of the first soaking cylinder 21, and the unqualified plastic fragments remain inside the crushing cylinder 101 for further crushing treatment;

[0044] Further, referring to Figure 7 and Figure 9 As shown, a water extraction pipe 37 is communicated at the top of the water storage bucket 35. The top of the water extraction pipe 37 is communicated with a second water guide pipe 38 connected to the shunt pipe 108. A second water pump 39 is fixedly installed at the connection between the water extraction pipe 37 and the water storage bucket 35. During actual use, the water filtered and entering the inside of the water storage bucket 35 is conveyed to the inside of the first water guide pipe 106 through the water extraction pipe 37, the second water guide pipe 38 and the plurality of shunt pipes 108 by the second water pump 39 for uniform spraying, and the natural fall of the water flow into the inside of the first soaking cylinder 21 is used to realize continuous water flow circulation, effectively reducing water resource waste and meeting environmental protection requirements.

[0045] In specific implementation, first, the plastic waste is crushed by the combined action of the double-layer crushing blades 104 and the directionally fixed blades 105 inside the crushing mechanism 101. At the same time, multiple spray heads 107 continuously spray water to initially wash the plastic particles during crushing, removing impurities such as dust and dirt;

[0046] Then, the crushed plastic particles, combined with the natural fall of the sprayed water, drop into the first soaking cylinder 21. The water flow in the soaking cylinder makes the light fragments float on the water surface and the heavy fragments sink to the bottom. At this time, the light and heavy plastic particles are initially separated by density stratification. Meanwhile, the scraper 29 reciprocates horizontally under the drive of the power assembly, scraping the light and heavy fragments respectively and pushing them into the guiding auxiliary cylinder 24. The plastic particles of different densities are screened by the first filter plate 210 during the movement;

[0047] After that, the water flow after screening enters the second soaking cylinder 31, and different-sized impurity particles are filtered layer by layer through the multi-layer second filter plate 32 to ensure the purity of the water flow. The filtered water is pumped by the water pump 36 and drained through the drain pipe 33 into the water storage bucket 35, and then is pumped through (39) and flows back into the interior of (108) via (37) and (38), and finally is evenly sprayed out through multiple (107) and reused for the crushing and screening processes, ensuring the recycling of water resources;

[0048] Finally, the plastic particles screened by density are further collected on an external traditional vibrating screening mechanism for screening of large and small particles, so as to ensure high purity and uniform particle size, thereby providing high-quality materials for subsequent plastic recycling and processing.

[0049] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected.
