Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a high-efficiency recycling device for waste plastics used in the production of decoration materials. Background Art

[0002] The main reasons for the generation of waste plastics in the production process of decoration materials include scraps and unqualified products in the processing of raw materials, a large number of plastic packaging materials used, production losses, plastic parts eliminated by product replacement, unqualified materials screened out by quality control, and difficulties in recycling. The generation of these waste plastics is closely related to factors such as production technology, environmental protection requirements and waste management. In order to reduce waste plastics and waste of resources, these waste plastics need to be recycled. The recycling of plastics includes steps such as collection, classification, cleaning, crushing, granulation and reprocessing. First, the waste plastics are collected and then classified according to the type and properties of the plastics; then, the classified plastics are crushed and crushed into small pieces or particles for subsequent processing; then they are cleaned and decontaminated to remove dirt and impurities; then they are dried and the crushed plastic particles are made into plastic pellets by heating and melting; finally, these plastic pellets can be used to make new plastic products to complete the recycling process of plastics.

[0003] However, in the process of cleaning the crushed plastic, ultrasonic cleaning is usually used. The cleaned plastic particles are conveyed by a conveyor belt to a drying device for drying. However, when the plastic is cleaned, since there is dirt in the water, the surface of the plastic is still covered with dirt when it is taken out by the conveyor belt. In the subsequent drying process, the dirt cannot be separated from the surface of the plastic particles, so the cleaning effect is poor, and the waste heat from drying cannot be recycled, so it is relatively energy-consuming. In the prior art, a Chinese patent with an authorization announcement number of CNB discloses an environmentally friendly plastic recycling device, including a cleaning box and a fluidizing cylinder. A filter cartridge is fixed inside the cleaning box, and a feed hopper for feeding material into the filter cartridge is fixed outside the cleaning box. The filter cartridge feeds material into the fluidizing cylinder through a feed pipe. A purification reflux mechanism is provided on one side of the cleaning box, and a stirring and mixing mechanism is provided inside the filter cartridge. The fluidizing cylinder is driven and connected to the stirring and mixing mechanism through an air guide pipe. The lower end of the fluidizing cylinder is connected to the hot air pump, and the upper end of the fluidizing cylinder is connected to the rotating sleeve through an air guide pipe, and one end of the air guide pipe can rotate relative to the rotating sleeve, and the other end is inserted into the fluidizing cylinder and is located above the upper filter plate. A plurality of suspension rods of different lengths are fixed to the bottom surface of the upper filter plate, and the lower ends of the suspension rods are rotatably connected to the propeller. A discharge valve is connected to the lower side wall of the fluidizing cylinder, and the connection between the discharge valve and the fluidizing cylinder is located above the lower filter plate.

[0004] This environmentally friendly plastic recycling equipment improves the cleaning effect and efficiency of plastic particles, but the multiple suspension rods of different lengths in the fluidized barrel are at different heights with large gaps, and the outlet of the guide pipe is located above the propeller, so that more plastic particles may not interact with the suspension rods and are blown to the vicinity of the upper filter plate by the airflow; secondly, because the outlet of the guide pipe directly faces the wind direction, some light plastic particles may always find it difficult to leave the outlet of the guide pipe under the thrust of the airflow, which may easily block the guide pipe and cause damage to the device. Therefore, it is necessary to improve the device to solve the above problems. Summary of the invention

[0037] Embodiment 1: Figures 1 to 3As shown, the present application is a high-efficiency recycling device for waste plastics used in the production of decoration materials, including a cleaning box 100, a fluidizing cylinder 200, a storage box 300 and a hot air pump 400, the fluidizing cylinder 200 is connected with a guide pipe 500, an air guide pipe 140, an air supply pipe 410, an upper discharge pipe 210 and a lower discharge pipe 220, the plastic particles 600 cleaned in the cleaning box 100 are fed into the fluidizing cylinder 200 by the guide pipe 500, the hot air pump 400 is connected with the bottom of the fluidizing cylinder 200 through the air supply pipe 410, and the top of the cleaning box 100 is connected with the top of the fluidizing cylinder 200 through the air guide pipe 140; a fluidizing chamber 240 is opened inside the fluidizing cylinder 200, an upper filter plate 241 is fixed on the upper part of the fluidizing chamber 240, a lower filter plate 242 is fixed on the bottom of the fluidizing chamber 240, and the upper discharge pipe 210 is located at the bottom of the upper filter plate 241 near the upper filter The lower discharge pipe 220 is located at the top of the lower filter plate 242 near the lower filter plate 242, and the upper discharge pipe 210 and the lower discharge pipe 220 are both connected to the storage box 300; the part of the guide pipe 500 located in the fluidizing chamber 240 is coaxially arranged with the fluidizing cylinder 200, the bottom of the guide pipe 500 is close to the lower filter plate 242, and a plurality of stirring fans 243 are coaxially sleeved on the guide pipe 500, and the stirring fans 243 are coaxially sleeved on the guide pipe 500. 43. The upper filter plate 241 and the lower filter plate 242 vertically divide the fluidizing chamber 240 into multiple sections; the air guide pipe 140 is located above the upper filter plate 241, and the air supply pipe 410 is located below the lower filter plate 242; a bulk plate 510 is connected to the bottom of the material guide pipe 500, and the diameter of the bulk plate 510 is larger than the diameter of the material guide pipe 500, and the upper end surface of the bulk plate 510 is connected to the opening edge of the material guide pipe 500 through a plurality of connecting columns 520.

[0038] The stirring fan 243 is annular in shape as a whole, and has a plurality of built-in blades that slide around an annular track, and is driven to rotate by the airflow blown out by the air supply pipe 410 .

[0039] The cleaning box 100 is connected to a feeding pipe 150, and a guide pipe 500 is connected to the top side wall of the feeding pipe 150; a feeding motor 151 is fixed to the end of the feeding pipe 150 away from the cleaning box 100, and a spiral blade shaft is coaxially installed in the feeding pipe 150, and the spiral blade shaft is connected to the output end of the feeding motor 151. The feeding motor 151 is used to transport the plastic particles 600 cleaned in the cleaning box 100 from the feeding pipe 150 to the guide pipe 500;

[0040] The top of the cleaning box 100 is connected to a liquid replenishing port 120, one side of the bottom of the cleaning box 100 is connected to a water outlet pipe 130, and a feed hopper 110 is fixed to the top of the cleaning box 100. The crushed plastic particles 600 are fed into the cleaning box 100 through the feed hopper 110. The liquid replenishing port 120 is used to replenish the cleaning liquid, and the water outlet pipe 130 is used to discharge sewage.

[0041] During operation, the cleaned plastic particles 600 are transported to the guide pipe 500 by the feeding motor 151, and fall from the guide pipe 500 to the bulk plate 510. The plastic particles 600 on the bulk plate 510 flow upward to the vicinity of the upper filter plate 241 along with the air flow blown out by the air supply pipe 410, and are dried by the hot air flow blown out by the hot air pump 400. The plastic particles 600 are disturbed once each time they pass through a stirring fan 243, thereby colliding with the stirring fan 243, and the plastic particles 600 will generate heat between each other. The plastic particles 600 collide with each other, thereby removing the stains attached to the plastic particles 600. After the plastic particles 600 flow to the vicinity of the upper filter plate 241, part of the stains are absorbed by the upper filter plate 241, and another part of the fine stains are transported to the cleaning box 100 through the air guide pipe 140, combined with the cleaning liquid and filtered, while the plastic particles 600 are intercepted by the upper filter plate 241 and enter the upper discharge pipe 210 from one side of the fluidizing chamber 240. After a round of plastic particles 600 processing is completed, the air supply pipe 410 stops transporting hot air.

[0042] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0043] 1. Make the movement length of the plastic particles 600 inside the fluidizing chamber 240 longer; thereby increasing the cleaning time of the stains on the surface of the plastic particles 600.

[0044] 2. The stirring fans 243 are arranged in multiple positions in the direction of travel of the plastic particles 600, thereby increasing the probability that each plastic particle 600 is stirred. The stirring fans 243 are driven to rotate by the airflow, and the coaxial setting makes the rotation of the multiple stirring fans 243 smoother, thereby improving the operating efficiency of the fluidizing chamber 240.

[0045] 3. By setting up upper and lower double discharge pipes, the upper and lower double discharge pipes cooperate with the vertically arranged stirring fans 243, so that a part of the plastic particles 600 are driven to the upper discharge pipe 210 by the airflow, and the other part is discharged from the discharge pipe after the airflow stops; the plastic particles 600 moving with the airflow in the fluidizing chamber 240 are discharged more smoothly and thoroughly after cleaning, thereby providing sufficient space for the plastic particles 600 discharged from the subsequent guide pipe 500.

[0046] 4. The bulk plate 510 blocks the airflow below to the periphery of the guide tube 500. When the plastic particles 600 fall to the bulk plate 510, they are driven into the fluidizing chamber 240 by the airflow, thereby reducing the possibility of blockage of the guide tube 500.

[0047] Embodiment 2: Considering the above embodiment 1, although the guide pipe 500 discharges the plastic particles 600 directly to the vicinity of the lower filter plate 242, and under the action of the bulk plate 510, the airflow will not directly act on the pipe mouth of the guide pipe 500, but there may be a certain amount of accumulation on the bulk plate 510. And when the plastic particles 600 are just released from the guide pipe 500, it is difficult to diffuse outward, and may only move upward along a path close to the wall of the guide pipe 500, thereby affecting the flow efficiency of the plastic particles 600. Secondly, some airflow may still enter the interior of the guide pipe 500, and the length of the guide pipe 500 is relatively long. The airflow will affect the falling trajectory of some lighter plastic particles 600. When the trajectory of some plastic particles 600 in the guide pipe 500 is offset, some debris or stains on the surface of the fragments are easy to adhere to the wall of the guide pipe 500. Therefore, it is necessary to improve the device, such as Figures 4 to 7 As shown, the specific structure is as follows:

[0048] The bulk material plate 510 is in the shape of a ring, and a bulk material cone 511 is coaxially covered at the center of the bulk material plate 510 ; the bulk material cone 511 is in the shape of a cone with its tip pointing upward, and the bulk material cone 511 is hollow inside and open at the bottom.

[0049] A vertical sliding rail 540 is provided inside the material guide tube 500, and a material collection assembly 530, a winding motor 531 and a winding rope 533 are slidably connected inside the sliding rail 540. The material collection assembly 530 includes a sliding ring 532, a pulling column 535, a material collection ring 536 and a material collection film 537. There are two winding motors 531, and the two winding motors 531 are symmetrically arranged on the outside of the material guide tube 500 at the top of the sliding rail 540. The sliding ring 532 is slidably connected to the sliding rail 540. The sliding ring 532 Two pulling columns 535 are connected to the bottom, and a tension sensor 534 is connected to the connection between the pulling column 535 and the sliding ring 532, and the tension sensor 534 is connected to the winding motor 531 by signal; the top of the sliding ring 532 is connected to the two winding motors 531 through two winding ropes 533, and the two winding ropes 533 slide through the side walls of the guide tube 500; the collecting ring 536 is fixedly connected to the bottom of the pulling column 535, and the two pulling columns 535 are symmetrically fixed to the upper end surface of the collecting ring 536;

[0050] The sliding ring 532 and the collecting ring 536 are both annular in shape and are coaxially arranged with the material guide tube 500 ; the collecting membrane 537 is fixed at the center of the collecting ring 536 , and the collecting membrane 537 is made of elastic rubber material and is used to carry the plastic particles 600 transported into the material guide tube 500 .

[0051] When the plastic particles 600 enter the material guide tube 500, they are caught by the aggregate film 537 and concentrated on the aggregate film 537. When the tension value received by the tension sensor 534 reaches the set value, the winding motor 531 releases the winding rope 533, causing the aggregate assembly 530 to freely fall downward. When the aggregate film 537 falls onto the bulk material cone 511, it comes into contact with the bulk material cone 511. The top of the bulk material cone 511 lifts the aggregate film 537 upward, causing the aggregate film 537 to deform. The plastic particles 600 on the aggregate film 537 diffuse to the surroundings due to the combined effect of inertia and the deformation of the aggregate film 537.

[0052] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0053] 1. Improving the diffusion efficiency of the plastic particles 600: Through the collision and cooperation between the aggregate film 537 and the bulk cone 511, the plastic particles 600 can be diffused more evenly when entering the fluidizing chamber 240, avoiding the situation where the plastic particles 600 only move along the wall of the guide tube 500, thereby improving the flow efficiency of the plastic particles 600.

[0054] 2. Part of the airflow that may enter the guide tube 500 is blocked for a second time by the aggregate film 537. The aggregate film 537 separates the plastic particles 600 from the airflow in the guide tube. Since the plastic particles 600 have just been cleaned and not dried, they have a certain amount of moisture. The plastic particles 600 are not easily attached to the inner wall of the guide tube 500 if they are not disturbed by the airflow.

[0055] 3. The bottom of the bulk cone 511 is open and hollow, so that the airflow diffuses after flowing to the bottom of the bulk cone 511, achieving a rectifying effect, making the airflow more dispersed, and being able to generate eddies near the bulk cone 511, thereby further helping the bulk cone 511 to break up the plastic particles 600.

[0056] Embodiment 3: Considering that in the above-mentioned embodiment 2, when the setting value of the tension sensor 534 is different, the falling speed of the aggregate assembly 530 is different, and the force of the bulk cone 511 on the aggregate film 537 is also different, when the setting value of the tension sensor 534 is large, it may cause the aggregate film 537 to be impacted too strongly, and it is easy for the plastic particles 600 on the aggregate film 537 to be pushed up to a high height, so that there is still a risk of adhesion to the opening of the guide tube 500. Secondly, the strong impact is also easy to reduce the service life of the device, so it is necessary to improve the device, such as Figure 8 As shown, the specific structure is as follows:

[0057] The soft part 512 is located at the center of the top of the bulk material cone 511. The soft part 512 is made of elastic rubber. The connecting column 520 is made of elastic rubber. The pulling column 535 is a hard rod. The length of the pulling column 535 is greater than the initial length of the connecting column 520 when it is not subjected to external force. When the setting value of the tension sensor 534 is large, after the aggregate film 537 impacts the bulk material cone 511 downward, the pulling column 535, the aggregate film 537 and the aggregate ring 536 exert pressure on the bulk material cone 511 under the gravity of the plastic particles 600, so that the bulk material The cone 511 moves downward, and at the same time, the connecting column 520 is stretched downward, so that the distance between the bulk plate 510 and the bottom opening of the guide tube 500 increases, providing a larger dispersion space for the plastic particles 600; at the same time, the soft part 512 and the connecting column 520 simultaneously buffer the plastic particles 600 on the aggregate film 537, thereby increasing the service life of the device; and the bottom of the soft part 512 is affected by the airflow and bulges upward, providing a buffer for the aggregate assembly 530 while obtaining a better rebound effect, so that the plastic particles 600 can be better dispersed.

[0058] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0059] 1. By arranging the soft part 512 and the connecting column 520 on the top of the bulk cone 511, the impact force generated when the aggregate film 537 falls can be effectively buffered, the damage to the device can be reduced, and the service life of the device can be extended.

[0060] 2. The stretching effect of the connecting column 520 can increase the diffusion space of the plastic particles 600 and reduce the risk of the plastic particles 600 sticking to the opening of the guide tube 500. The downward movement of the bulk cone 511 increases the distance between the bulk plate 510 and the bottom opening of the guide tube 500, which is more conducive to the uniform dispersion of the plastic particles 600.

[0061] 4. The bottom of the soft part 512 bulges upward due to the airflow, which not only provides a buffer but also enhances the rebound effect, thus helping to better disperse the plastic particles 600.

[0062] 5. Through the cooperation of the pulling column 535, the connecting column 520 and the soft part 512, the device can adapt to the setting values ​​of different tension sensors 534, and use gravity to flexibly adjust the falling speed of the aggregate assembly 530 and the force of the bulk cone 511.

[0063] Embodiment 4: Considering that in the above-mentioned embodiment 3, the intensity of the airflow is limited by the working intensity of the hot air pump 400, when the hot air pump 400 works for a long time, its airflow intensity will fluctuate, and the cleanliness of the plastic particles 600 and the rotation speed of the stirring fan 243 are affected by the airflow intensity. When the airflow intensity is high, the number of plastic particles 600 that can be driven is also higher, and when the airflow intensity is weak, the number of plastic particles 600 that can be fully processed is also less, so it is necessary to improve the device, such as Fig. 9 and Fig.10 As shown, the specific structure is as follows:

[0064] The soft part 512 is hollow inside, and a buffer cavity 513 is opened inside the soft part 512. The buffer cavity 513 is filled with a buffer solution, and the buffer solution is preferably silicone oil. Since silicone oil has good thermal stability and low viscosity, it can maintain stable fluidity when the temperature changes, and is suitable as a buffer medium, so that it can be affected by the intensity of airflow. When the airflow is strong, the soft part 512 bulges upward into a cone shape under the support of the airflow. When the airflow is weak, the paraffin in the buffer cavity 513 drives the soft part 512 to deform downward under the action of its own gravity, so that the top of the soft part 512 is relatively flat.

[0065] In the working state, when the intensity of the airflow is greater, the slope of the soft part 512 is steeper, the plastic fragments on the aggregate film 537 are more dispersed, and can diffuse out faster; when the intensity is smaller, the slope of the top of the soft part 512 is gentler, so that the soft part 512 deforms downward more, and all the plastic fragments will not be splashed out at the same time. Some plastic fragments in the middle of the aggregate film 537 will diffuse out more slowly as the airflow pushes the bottom of the soft part 512 to generate shaking, so that the weaker airflow acts on the plastic fragments for a longer time, and the amount of plastic fragments processed per unit time is reduced, so that the surface stains of the plastic fragments can be processed more thoroughly and dried more thoroughly.

[0066] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0067] 1. The buffer can automatically adjust the deformation of the soft part 512 according to the change of airflow intensity, optimize the dispersion speed and angle of the plastic particles 600, adapt to different airflow intensities, improve the processing efficiency of the plastic particles 600, and fully dry and decontaminate the plastic particles 600.

[0068] 2. The buffer acts as a buffer medium, effectively reducing the impact of air flow fluctuations on the device, protecting the device structure and further extending its service life.

[0069] 3. The action time of weak airflow on the plastic particles 600 is prolonged. When the airflow is weak, the gentle deformation of the soft part 512 prevents the plastic particles 600 from splashing out immediately, but gradually disperses with the push of the airflow, thereby prolonging the action time of the weak airflow on the plastic particles 600 and improving the cleaning effect.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
