Abstract
Description
Technical Field
[0001] This invention relates to the field of plastic masterbatch recycling and processing technology, specifically to a plastic masterbatch recycling and processing equipment. Background Technology
[0002] Plastic masterbatch, often referred to as colorant, is typically a concentrated granule made by uniformly dispersing an excessive amount of pigment or dye into a resin carrier. In the production of various products such as plastics, fibers, and rubber, masterbatch is often used to achieve precise and stable coloring. When recycling waste plastics containing masterbatch, a flotation washing tank is generally used to wash and float the crushed plastic fragments, thereby utilizing the density differences of different plastic materials and impurities in water to achieve the dual purpose of separating impurities and sorting plastics of different materials.
[0003] In existing technologies, when flotation separation is performed on crushed plastic containing masterbatch, the crushed plastic fragments are generally fed into the rear end of the flotation washing tank. The water flow slowly moves the plastic fragments towards the front collection port, and multiple sets of stirring devices on the tank continuously disperse the plastic fragments, causing the light fragments to float continuously while the high-density materials and impurities sink steadily. The light fragments floating on the liquid surface are then transported to the next process by the lifting device through the collection port, while the heavy materials that sink to the bottom are transported to the next process by the bottom spiral conveyor.
[0004] However, the traditional method of flotation of plastic fragments using a flotation washing tank has the following problems: 1. In the existing technology, due to the fluctuation in the density composition of the plastic fragments fed into the flotation washing tank, there may still be dynamic exchange of fragments of different densities at the end of the washing tank during the sorting process. Furthermore, since the existing washing tank does not have the ability to judge and adjust in real time, some of the floating light fragments are blocked by the baffle at the lower end of the collection port and cannot be automatically collected. They must be manually retrieved and cleaned afterward, which not only increases the operational burden but also affects the sorting efficiency and effect; 2. In the existing technology, the stirring device of the flotation washing tank is concentrated on the surface, which is difficult to handle the entrainment of low-density fragments by high-density materials in the middle and lower layers. Moreover, since the proportion of low-density fragments in the suspended clumps near the surface is relatively high, if they are not broken up in time, the entrained fragments will not be able to float or will float up with a delay. This not only extends the sorting process to the end of the tank, further increasing the proportion of light fragments that cannot be automatically collected, but also affects the sorting purity and recycling efficiency.

[0015] Preferably, the multi-point sampling unit includes multiple L-shaped tube grooves formed on the mounting base and the cleaning tank. A manifold valve is fixedly installed on the right side of the cleaning tank and is connected to each corresponding L-shaped tube groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the cooperation of the adjustment mechanism, the dispersing mechanism and the detection mechanism, can separate the surface lightweight plastic fragments adjacent to the rear side of the collection port from the middle and lower layer materials. By sampling and filtering the water body below the surface and visual recognition, it can determine in real time whether the plastic fragments behind the collection port are still being sorted and exchanged. Based on the determination result, if there is still material sorting and exchange, the surface fragments are continued to be dispersed and sorted. If the sorting is completed, the surface fragments are no longer dispersed, but are directly collected. At the same time, the filtered fragments can be dispersed by water flow and returned to the tank to prevent material loss. Thus, while ensuring the purity of collection, it effectively reduces the energy consumption and interference of excessive stirring and reduces manual intervention, thereby significantly improving the sorting efficiency, stability and accuracy.
[0019] 2. By coordinating the adjustment mechanism, the dispersing mechanism, and the detection mechanism, this invention can also achieve targeted dispersal of suspended clumps containing lightweight fragments below the sampling area, while avoiding the bottom heavy material layer and the surface light material layer. This efficiently disperses the clumps and releases the lightweight fragments, improving the recovery rate and sorting purity, and avoiding disturbance to the upper, lower, and front sorting interfaces. Furthermore, it can dynamically start and stop based on the sampling judgment results, thereby ensuring the stable collection of pure fragments from the upper layer while effectively handling the clumps in the middle, and significantly improving the sorting purity, effect, efficiency, and overall recovery rate.

Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figure 1 A plastic masterbatch recycling and processing equipment includes a cleaning tank 1 with a collection port at the front end and a screw conveyor at the bottom, a lifting device on the upper side of the collection port, an adjustment mechanism 2 on the cleaning tank 1, a dispersing mechanism 3 on both the cleaning tank 1 and the adjustment mechanism 2, and a detection mechanism 4 on both the cleaning tank 1 and the dispersing mechanism 3.
[0033] Please see Figure 1The adjustment mechanism 2 includes a lifting adjustment part 21 disposed on the cleaning tank 1 for vertical movement adjustment, and a rotation adjustment part 22 disposed on the cleaning tank 1 for fixed angle rotation adjustment.
[0034] Please see Figure 1 and Figure 3 The lifting adjustment unit 21 includes two sets of fixed platforms 211 fixedly installed on the outer side of the front section of the cleaning tank 1. Each set consists of left and right symmetrical fixed platforms 211. A multi-stage cylinder 212 with a telescopic end passing through the fixed platform 211 is fixedly installed on the lower side of the fixed platform 211.
[0035] Please see Figure 1 , Figure 2 and Figure 3 The rotation adjustment unit 22 includes a partition plate 221 that is vertically distributed and rotatably mounted in the cleaning tank 1 at a fixed angle via a rotating shaft. The two partition plates 221 correspond one-to-one with two sets of fixed platforms 211. Multiple through holes are evenly provided on the partition plate 221. The rear side of the lower end of the partition plate 221 is an arc surface. A motor 222 that drives the corresponding partition plate 221 to rotate at a fixed angle is fixedly mounted on the left side of the cleaning tank 1 via a support. The driving end of the motor 222 is fixedly connected to the rotating shaft on the corresponding partition plate 221.
[0036] Motor 222 can drive the corresponding partition plate 221 to rotate from a vertical position to a horizontal position. The through holes can reduce the resistance of the partition plate 221 to the water in the cleaning tank 1 during rotation and reduce the disturbance of the partition plate 221 to the nearby water. The rotation speed of the partition plate 221 driven by motor 222 and the size and arrangement of the through holes of the partition plate 221 are precisely calculated and designed by those skilled in the art. This not only ensures stable interception of plastic fragments in the water in front of and behind the partition plate 221, but also minimizes interference with the sorting of plastic fragments in the water near the partition plate 221.
[0037] Please see Figure 1 and Figure 2 The dispersing mechanism 3 includes a stirring and dispersing part 31, which is jointly provided on the washing tank 1 and the lifting adjustment part 21 and is used to stir and disperse the floating plastic fragments on the surface. The washing tank 1 is provided with a sorting part 32 to separate the surface light plastic fragments from the middle and lower layers of materials. The sorting part 32 is provided with a swinging dispersing part 33 to specifically disperse the suspended clumps containing light fragments. The sorting part 32 and the washing tank 1 are jointly provided with a swinging drive part 34 to drive the swinging dispersing part 33.
[0038] Please see Figure 1 , Figure 2 and Figure 3The stirring and dispersing section 31 includes two sets of rotating seats 311 that are directly fixed to the rear of the washing tank 1 via a support two. A set of rotating seats 311 that move up and down are also fixedly installed on the telescopic end of a multi-stage cylinder 212. Each set of rotating seats 311 consists of left and right symmetrical rotating seats 311. A stirring roller 312 is rotatably installed on each set of rotating seats 311. A motor two 313 that drives the corresponding stirring roller 312 to rotate in a specific direction is fixedly installed on the left side of the left rotating seat 311. The driving end of the motor two 313 is fixedly connected to the left end of the corresponding stirring roller 312.
[0039] When sorting and cleaning plastic fragments, the crushed plastic fragments are first fed into the rear end of the cleaning tank 1. Then, each motor 313 drives the corresponding stirring roller 312 to rotate and stir, so as to drive the water to flow forward continuously. At the same time, the plastic fragments accumulated on the surface of the water are continuously conveyed and dispersed, so that the plastic fragments are continuously dispersed in the water. This causes the light fragments to float continuously while the high-density materials and impurities sink steadily until the light fragments floating on the surface enter the lifting equipment through the collection port and are conveyed to the subsequent process. Meanwhile, the heavy materials that sink to the bottom are conveyed to the subsequent process through the bottom spiral conveyor. The amount of plastic fragments fed in, the rotation speed of the stirring roller 312, the flow rate of the water, and the length of the cleaning tank 1 are all precisely calculated and designed by those skilled in the art to ensure the overall sorting effect and efficiency of the plastic fragments.
[0040] Please see Figure 2 , Figure 3 and Figure 4 The sorting unit 32 includes sorting plates 321 that are fixedly arranged in the cleaning tank 1 and horizontally distributed. The sorting plates 321 are located behind the corresponding partition plates 221. The rear end of the sorting plates 321 is an arc surface. A mounting base 322 is fixedly arranged in the cleaning tank 1 and below the sorting plates 321.
[0041] Please see Figure 2 , Figure 5 and Figure 6 The swinging dispersing part 33 includes multiple rotating rods 331 that are evenly rotated left and right at the rear end of the mounting base 322. Multiple dispersing plates 332 are evenly fixed on the rotating rods 331 and below the mounting base 322. A mounting groove 333 extending left and right is opened at the rear end of the mounting base 322 and on the upper side of the rotating rods 331. A half gear 334 located in the mounting groove 333 is fixed on the upper side of the rotating rods 331.
[0042] Please see Figure 2 , Figure 5 and Figure 6The swing drive unit 34 includes a rack 341 that is slidably disposed in the mounting groove 333 and meshes with the corresponding half gear 334. Adjacent racks 341 are fixedly connected by a connecting rod extending left and right. A hydraulic cylinder 342 is fixedly disposed on the right side of the cleaning tank 1 by a support three. The telescopic end of the hydraulic cylinder 342 is fixedly connected to the right side of the rightmost rack 341 by a connecting rod that slides left and right through the right side of the cleaning tank 1.
[0043] When it is necessary to break up suspended clumps containing lightweight fragments in water at a certain depth below the surface, the hydraulic cylinder 342 drives the corresponding connecting rod 2 and the rightmost rack 341 to move back and forth. The corresponding adjacent racks 341 move back and forth synchronously through the connected connecting rod 1, and through the meshing transmission with the corresponding half gear 334, drive the rotating rod 331 and the breaking plate 332 on it to swing left and right, thereby breaking up the suspended clumps and releasing the lightweight fragments that are trapped inside. The setting depth, swing amplitude and distribution of the breaking plate 332 are precisely calculated and designed by those skilled in the art to ensure targeted breaking up of suspended clumps and avoid interference with the sorting of plastic fragments.
[0044] When the sorted plastic fragments drift with the water flow to the sorting plate 321, the sorting plate 321 separates the surface lightweight plastic fragments adjacent to the back of the collection port from the middle and lower layer materials. At the same time, the detection mechanism 4 continuously samples and tests the water body below the sorting plate 321.
[0045] If the testing agency 4 detects the presence of plastic fragments in the water sample, it indicates that the plastic material in the water above and below the sorting plate 321 is still being exchanged and sorted. In this case, the corresponding stirring roller 312 above the sorting plate 321 can continue to disperse the plastic material, and the dispersing plate 332 can be simultaneously oscillated to disperse the suspended clumps below the sorting plate 321, thus promoting the continued sorting of plastic fragments in the water above and below the sorting plate 321. Suspended clumps and fragments in the water at a certain depth below the sorting plate 321 are blocked by the separating plate 221 and cannot be separated. The material continues to drift forward, while the fragments above the sorting plate 321 continue to drift backward and disperse until they reach the next sorting plate 321 and the detection mechanism 4 for detection and judgment. The sorting plate 321 and the partition plate 221 can largely avoid interference from the oscillating and dispersing of the material on the surface and in front of the partition plate 221, and completely prevent the oscillating and dispersing material from mixing again with the unsorted material on the upper side of the sorting plate 321 and in front of the partition plate 221, thereby effectively improving the sorting effect and efficiency.
[0046] If the detection mechanism 4 determines that the sorting plate 321 has reached a sorting state without material exchange, it first stops the stirring roller 312 and the dispersing plate 332 corresponding to the sorting plate 321, and drives the rotating seat 311 and the stirring roller 312 to move upward through the corresponding multi-stage cylinder 212 to avoid the stirring roller 312 interfering with the light fragments that have been sorted on the surface. Then, the corresponding vertical partition plate 221 is rotated forward to a horizontal state, so that the light fragments that have been dispersed and released below the sorting plate 321 and the partition plate 221 can continue to drift forward and float to the water surface from the front end of the horizontal partition plate 221 to merge with the light fragments above the sorting plate 321. Thus, the sorted light fragments are stably entered into the collection port under the guidance of the two sets of sorting plates 321 and the partition plate 221, and are transported to the next process under the action of the lifting equipment. At the same time, the heavy material below the water can also be transported to the next process under the action of the screw conveyor.
[0047] It should be noted that, with precise calculations and design by those skilled in the art, the situation where a large amount of material continues to be separated in the adjacent water body behind the collection port is rare. Even if separation occurs due to fluctuations in the density composition of the input plastic fragments, the amount of material exchanged and separated is not dense. Through the cooperation of the two sets of sorting plates 321 and the detection mechanism 4, it is sufficient to ensure that the lightweight plastic fragments completely and stably enter the collection port for conveying. The above-mentioned operation method ensures the purity of collection, effectively reduces the energy consumption and interference of excessive stirring, reduces manual intervention, significantly improves sorting efficiency, stability and accuracy, effectively handles the central clumps, and significantly improves sorting purity and overall recovery rate.
[0048] Please see Figure 1 and Figure 4 The detection mechanism 4 includes a multi-point sampling unit 41, which is jointly provided on the cleaning tank 1 and the sorting unit 32 and is used to sample the water body below the surface at multiple points. The multi-point sampling unit 41 is provided with a filter detection unit 42 for visually identifying the number of plastic fragments in the water sample after filtration and a return unit 43 for breaking up and returning the filtered plastic fragments.
[0049] Please see Figure 4 , Figure 6 , Figure 7 and Figure 8The multi-point sampling unit 41 includes multiple through L-shaped tubes 411 evenly spaced on the mounting base 322 and the cleaning tank 1. The L-shaped tubes 411 are located in front of the corresponding mounting tank 333, and the rear end of the L-shaped tubes 411 is connected to the interior of the cleaning tank 1. A manifold valve 412 is fixedly installed on the right side of the cleaning tank 1 and is connected to the right end of each corresponding L-shaped tube 411. The manifold valve 412 is used to collect water samples flowing into each corresponding L-shaped tube 411. A filter chamber 413 is fixedly installed on the right side of the cleaning tank 1 and below the corresponding manifold valve 412 through a support four. The right side of the manifold valve 412 is connected to the filter chamber 413 through a connecting pipe one.
[0050] Please see Figure 4 , Figure 8 , Figure 9 and Figure 10 The filter detection unit 42 includes a turntable 421 rotatably disposed inside the filter chamber 413. A motor 422 for driving the turntable 421 to rotate is fixedly disposed on the upper side of the filter chamber 413. The driving end of the motor 422 is fixedly connected to the upper side of the turntable 421. A plurality of scrapers 423 with pointed ends are evenly disposed circumferentially on the turntable 421. The upper ends of the scrapers 423 are close to the corresponding inner wall of the filter chamber 413. A filter screen 424 for filtering plastic fragments in the water sample is fixedly disposed between each scraper 423. A visual sensor 425 for visually identifying the number of plastic fragments in the space enclosed by the lower scraper 423 and the corresponding filter screen 424 is symmetrically disposed on the upper side of the filter chamber 413. The lower end of the visual sensor 425 penetrates the upper side of the filter chamber 413 and is isolated from the water sample inside the filter chamber 413 by a transparent protective cover.
[0051] Please see Figure 4 , Figure 7 and Figure 8 The return section 43 includes a pump 431 fixedly installed on the lower side of the filter chamber 413. The pump 431 is symmetrically fixed with a connecting pipe 2 whose upper end is connected to the filter chamber 413. The upper end of the left connecting pipe 2 is aligned with the lower end of the corresponding connecting pipe. A return pipe 432 is fixedly installed on the upper right side of the filter chamber 413. The lower end of the return pipe 432 is aligned with the upper end of the right connecting pipe 2. The upper end of the return pipe 432 is located above the cleaning tank 1.
[0052] When the water body below the sorting plate 321 is to be extracted and tested, the turntable 421 and its scrapers 423 and filter screens 424 are driven by motor 3 422 to rotate continuously in a directional manner. The pump 431 continuously extracts the water body at the rear end of each L-shaped pipe groove 411, so that the water flow continuously flows from the L-shaped pipe groove 411 into the manifold valve 412, and then flows down into the left end of the filter chamber 413 through the manifold valve 412 and connecting pipe 1. The water flow into the left end of the filter chamber 413 then continuously enters the filter space formed by each filter screen 424 and the corresponding scraper 423, and passes through the filter screen 424 into the left connecting pipe 2. The plastic fragments remaining in the water flow are intercepted in the corresponding filter space and continue to rotate with the turntable 421 to below one of the vision sensors 425. The vision sensor 425 then continuously identifies whether there are plastic fragments in each filter space it passes through. If there are, it means that the sorting is still ongoing; otherwise, the sorting is completed.
[0053] The water flowing into the left connecting pipe 2 is pumped by pump 431 through the right connecting pipe 2, and then enters the right end of the filter chamber 413 again, and washes the filtered screen 424 from bottom to top, thereby washing and breaking up the plastic fragments in the screen 424 and its corresponding filter space and sending them into the return pipe 432. Finally, the water is sent back to the cleaning tank 1 from the upper end of the return pipe 432 to prevent material loss and clogging of the screen 424, while ensuring the overall material recovery rate.
[0054] As the filter screen 424 continues to rotate after rinsing, it rotates to a position below another vision sensor 425. The vision sensor 425 then identifies each filter screen 424 and its filtration space to determine whether the surface debris of the filter screen 424 has been completely rinsed clean. This avoids interference from residual plastic debris on the filter screen 424 after rinsing, which could affect the sorting of plastic debris in the water, thus ensuring the accuracy and stability of the real-time detection results.
[0055] Each scraper 423 continuously cleans the inner wall of the filter chamber 413 and the transparent protective cover at the lower end of the vision sensor 425 to prevent plastic fragments from adhering to the inner wall of the filter chamber 413 and the lower end of the vision sensor 425, thus eliminating the interference of the adhering fragments on the judgment of the sorting results. Furthermore, it should be noted that the rotation speed of the turntable 421, the distribution of the filter screen 424, the selection of the vision sensor 425, the power of the pump 431, and the position of the return material and water flow in the return pipe 432 are all precisely calculated and designed by those skilled in the art to ensure continuous and accurate judgment of the presence of plastic fragments in the sampled water, thereby ensuring accurate response to the material sorting situation in the water.
[0056] It should be noted that existing technologies can also determine the material sorting and exchange status in the water at the collection port of the washing tank 1 and start / stop the stirring device by setting a transparent observation window and a visual sensor 425 at the collection port of the washing tank 1. However, this only solves the final determination of the sorting status and optimizes the energy consumption and interference problems of excessive stirring. Although it improves the control of sorting effect and efficiency to a certain extent, there are still unresolved problems in terms of accurate response to the determination results, improvement of sorting efficiency and effect, targeted dispersal of suspended agglomerates, and optimization of sorting purity and overall recovery rate. This not only affects the sorting results and efficiency but also affects the subsequent processing quality of the materials. However, in the solution of this invention, the adjustment mechanism 2, the dispersing mechanism 3, and the detection mechanism 4 work together to not only achieve the desired results but also improve the overall quality of the material. This invention enables precise judgment of the sorting situation, accurately responds to different material sorting states, and specifically releases suspended clumps. It also effectively reduces energy consumption and interference from excessive stirring, thereby significantly improving sorting purity, effect, efficiency, and overall recovery rate. Furthermore, compared to existing plastic fragment flotation equipment, the added adjustment mechanism 2, dispersing mechanism 3, and detection mechanism 4 are all conventional mechanical components, without any high-cost precision parts. They require only a one-time investment for long-term use, making the cost of adding these structures low. Compared to the economic benefits brought by the significant improvement in sorting purity, effect, efficiency, and overall recovery rate, the cost of adding these structures is negligible. In summary, the above-mentioned technical solution of this invention is a specific improvement based entirely on the existing technology and aimed at solving the technical problems.
