Description

Technical Field

[0001] The invention relates to the field of plastic recycling devices, and in particular to a plastic recycling and cleaning device. Background Art

[0002] With the acceleration of global industrialization and the continuous growth of population, the consumption of plastic products has also shown a blowout growth. However, behind this growth lies a serious environmental problem - the treatment and recycling of plastic waste. Due to its non-degradable nature, if plastic waste is not handled properly, it will not only cause long-term pollution to the soil, water sources and ecosystems, but also occupy a large amount of land resources.

[0003] However, there are also many plastic products in industrial production, such as plastic pallets, etc. In the production process of plastic products, waste is inevitable. At this time, the waste needs to be crushed and reused while protecting the environment.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0041] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0042] like Figures 1 to 13 As shown, the present invention is a plastic recycling and cleaning device, comprising: a machine body 1, a crushing station 2, a feeding station 3 and a cleaning station 4 are arranged on the machine body 1; the crushing station 2 is used to crush the recycled plastic; the feeding station 3 is used to convey the crushed plastic fragments to the cleaning station 4; the cleaning station 4 is used to clean the plastic fragments conveyed to the cleaning station 4;

[0043] The present application can be used in conjunction with a conveying mechanism, which is used to transport the plastic parts to be recycled to the feed port of the crushing station 2. The specific structure of the conveying mechanism is preferably: a belt conveying mechanism.

[0044] The crushing station 2 includes: a crushing box 21 fixedly mounted on the machine body 1, a crushing knife 22 rotatably mounted in the crushing box 21, and a motor 23 driving the crushing knife 22 to rotate; the discharge port of the crushing box 21 is located above the receiving cavity 33;

[0045] At this time, the conveying mechanism drops the plastic parts to be cleaned into the crushing box 21, and drives the motor three 23. Since the output shaft of the motor three 23 is fixedly connected to the crushing knife 22, the crushing knife 22 is driven to rotate, and the plastic parts in the crushing box 21 are crushed into plastic fragments of the size to be recycled. The crushed plastic fragments fall into the receiving chamber 33 through the discharge port of the crushing box 21 to collect the crushed fragments.

[0046] A fan 24 is also provided on one side of the crushing box 21 for collecting dust generated when the plastic is crushed. When the plastic parts are crushed, the fan 24 is started to suck air out of the crushing bin to discharge the dust generated in the crushing bin due to crushing. On the one hand, it prevents excessive dust from escaping from the body 1 and causing inhalation by the staff, affecting the health of the staff. On the other hand, the dust in the plastic fragments is initially sucked out by the fan 24 to reduce the amount of dirt on the plastic fragments, thereby increasing the cleaning effect for subsequent comprehensive cleaning and reducing the frequency of changing the cleaning water, thereby further saving water.

[0047] It should be added here that the exhaust port of the fan 24 is also provided with a filtering mechanism, through which the dust sucked out of the crushing bin is further filtered; the filtering mechanism is a prior art, so it will not be described in detail here.

[0048] The feeding station 3 includes: a feeding trough 31 fixedly mounted on the machine body 1, a turntable 32 rotatably mounted on the feeding trough 31, a material receiving chamber 33 fixedly mounted on the turntable 32, and a driving motor 34 for driving the turntable 32 to rotate;

[0049] When the plastic fragments in the receiving trough are full, the driving motor 34 is started immediately, and the turntable 32 rotates on the feeding trough 31 under the drive of the driving motor 34, and the receiving chamber 33 fixedly mounted on the turntable 32 rotates accordingly, and the receiving chamber 33 filled with plastic fragments will move to above the cleaning box 40 of the cleaning station 4, and at the same time, the empty receiving chamber 33 will be transported to the lower end of the crushing bin to prepare for receiving new fragments, thereby realizing the parallel cleaning and crushing work, effectively reducing the mechanical idling time, and greatly improving the overall work efficiency.

[0050] A feeding port 311 is provided in the feeding trough 31, and a lifting plate 312 which gradually rises with the rotation direction of the turntable 32 is fixedly installed on one side of the feeding port 311, and the highest side of the lifting plate 312 is fixedly connected to one side of the feeding port 311; a built-in bin 331 is slidably installed in the inner sleeve of the receiving cavity 33, and a mesh 334 smaller than the plastic fragments is provided on the built-in bin 331;

[0051] When the receiving chamber 33 moves to above the cleaning box 40, since the built-in bin 331 is slidably installed in the receiving chamber 33, and when the receiving chamber 33 rotates to the discharge port 311 at the upper end of the cleaning, the built-in bin 331 moves downward along the receiving chamber 33 under the influence of gravity, causing the built-in bin 331 to pass through the discharge port 311 and enter the cleaning box 40. At the same time, the plastic fragments in the collecting chamber move downward synchronously with the built-in bin 331 into the cleaning box 40, and the cleaning solution in the cleaning box 40 passes through the mesh 334 of the built-in bin 331 and contacts the plastic fragments, which is convenient for subsequent cleaning; when the cleaning is completed, continue to rotate the turntable 32 in the same direction. At this time, the built-in bin 331 will gradually slide upward under the guidance of the lifting plate 312, so that the built-in bin 331 can return to the feeding trough 31 to facilitate the discharge and re-loading of the cleaned plastic fragments; thereby completing the material transmission work.

[0052] A protrusion 332 is provided at the bottom of the material receiving chamber 33, and a protrusion 333 abutting against the protrusion 1 332 is provided at the top of the built-in bin 331; when the top of the built-in bin 331 slides along the inner wall of the material receiving chamber 33 to the bottom of the material receiving chamber 33, the protrusion 2 333 abuts against the protrusion 1 332, thereby limiting the built-in bin 331 and preventing the built-in bin 331 from completely separating from the material receiving chamber 33.

[0053] It should be added here that a pressure sensor is also provided at the bottom of the built-in cavity. When the plastic fragments in the built-in bin 331 gradually increase as the crushing station 2 continuously crushes the plastic parts, the pressure sensor sets a specified threshold value for the amount of plastic fragments in the built-in cavity. When the mass accumulation of the plastic fragments in the built-in bin 331 reaches this threshold value, an abnormal signal is sent to the alarm. The alarm makes an abnormal sound to remind the staff to stop the operation of the crushing station 2 and start the motor 34. The motor 34 drives the fully loaded receiving cavity 33 to move to the top of the cleaning station to clean the crushed particles to remove surface dirt. Therefore, the amount of plastic fragments entering the cleaning box 40 each time can be accurately controlled by the above mechanism. The water in a cleaning box 40 can clean the plastic fragments in the built-in cavity several times to determine the time for replacing the cleaning water in the cleaning box 40 each time, so as to prevent the water in the cleaning box 40 from being replaced in time, resulting in poor cleaning effect, or the problem of wasting water resources due to constantly changing new water; at the same time, when cleaning the plastic fragments, the plastic fragments will be connected to the built-in warehouse 331 and immersed in the cleaning box 40 at the same time. Since the mesh 334 on the built-in net is smaller than the width of the plastic fragments, the plastic fragments will not separate from the built-in net when flushing in the cleaning box, and will be scattered and float in the cleaning box 40, resulting in that when the water in the cleaning box 40 is replaced, the plastic fragments in the cleaning box 40 need to be cleared, thereby affecting work efficiency.

[0054] The cleaning station 4 includes: a cleaning box 40 fixedly mounted on the lower end of the machine body 1, a stirring paddle 41 for stirring the plastic fragments in the receiving chamber 33, a driving bevel gear 42 sleeved on the stirring rod, a driven bevel gear 43 rotatably mounted on the stroke of the driving bevel gear 42, a cam 44 for flipping the plastic fragments in the receiving chamber 33 up and down when rotating, a motor 45 for driving the stirring paddle 41 to rotate, and a cylinder 46 for driving the stirring paddle 41 to move up and down; the driven bevel gear 43 is synchronously connected with the cam 44 through a linkage assembly 47, and draws water in the cleaning box 40 to the spray assembly 48 at the upper end of the receiving chamber 33 as the cam 44 rotates;

[0055] When the built-in bin 331 is immersed in the cleaning box 40, the cylinder 46 pushes the stirring paddle 41 to move into the built-in bin 331 until the active bevel gear 42 on the stirring paddle 41 is meshed with the driven bevel gear 43. At this time, the motor is started, and the motor drives the stirring paddle 41 to rotate to stir and clean the plastic fragments in the built-in bin 331. At the same time, the active bevel gear 42 drives the driven bevel gear 43 to rotate. When the driven bevel gear 43 rotates, it synchronously drives the cam 44 installed under the built-in bin 331 to rotate through the linkage assembly 47. Here, the linkage assembly 47 is used to connect the cam 44 installed under the built-in bin 331. The moving component 47 is preferably a belt, but it can be replaced by a gear chain. The rotation of the cam 44 will quickly push the built-in bin 331 to move up and down in the receiving chamber 33, so that the plastic fragments in the built-in bin 331 can be turned up and down. At the same time, the cam 44 continuously strikes the built-in bin 331, and the plastic fragments in the built-in bin 331 will not block the mesh 334 of the built-in bin 331, so that the stained water in the built-in bin 331 can circulate with the clean water in the cleaning box 40, further enhancing the cleaning effect of the plastic fragments.

[0056] It should be added here that since the number of revolutions of the stirring paddle 41 is required to be very high, and the direct transmission connection between the stirring paddle 41 and the cam 44 through the linkage assembly 47 may cause the cam 44 to rotate too fast, thereby affecting the service life of the machine. The present application reduces the rotation speed of the cam 44 by adding a reduction mechanism to the linkage assembly 47, thereby extending the service life of the machine. The reduction mechanism here can specifically be a large and small gear reduction mechanism.

[0057] A capsule 411 is also provided at the bottom of the inner cavity of the cleaning box 40, and an extrusion plate 412 is fixedly installed on the capsule 411. The air outlet of the capsule 411 is connected to the cleaning box 40 through an air pipe 413, and a one-way valve is provided on the air pipe 413;

[0058] When the cam 44 rotates, it will also synchronously squeeze the squeezing plate 412 on the capsule 411, causing the squeezing plate 412 to move downward and compress the capsule 411, so that the gas in the capsule 411 is filled into the water in the cleaning box 40 through the air pipe 413, so that a large number of bubbles are generated in the cleaning box 40 to increase the contact area between water and plastic fragments, thereby improving the cleaning efficiency. It should be noted here that in actual cleaning, it is often necessary to add cleaning agent to the cleaning box 40 to speed up the cleaning efficiency. By squeezing the capsule 411 to generate bubbles in the box, more cleaning liquid can contact the surface of the fragments to improve the cleaning effect. A one-way valve is set to prevent the water in the box from flowing back into the capsule 411.

[0059] It should be noted here that the air inlet of the bladder 411 passes through the side wall of the cleaning box 40; when the bladder 411 is compressed and expands, it absorbs air outside the cleaning box 40 through the air inlet to expand.

[0060] Due to the different materials and densities of plastics, some plastic fragments float on the water surface. When cleaning the plastic fragments floating on the water surface, there is always one surface that is not in contact with the water, which leads to the problem of poor cleaning effect of the plastic fragments floating on the water surface;

[0061] The spray assembly 48 includes: a water pipe 481 penetrating the side wall of the cleaning box 40, an impeller 482 rotatably installed in the water inlet of the water pipe 481, a sliding groove 483 provided on the inner wall of the water pipe 481, a filter 484 slidably installed in the sliding groove 483, a nozzle 485 installed above the material receiving chamber 33, and an anti-blocking assembly 486 for preventing the filter 484 from being blocked; the filter 484 is elastically connected to a side wall of the sliding groove 483 by a spring 487, and the nozzle 485 is fixedly connected to the water outlet of the water pipe 481;

[0062] The driven bevel gear 43 synchronously drives the cam 44 to rotate, and synchronously drives the impeller 482 to rotate. The impeller 482 can be coaxially fixedly connected to the cam 44 through a connecting piece. When the impeller 482 rotates, the water in the cleaning box 40 will be drawn into the water pipe 481, and guided to the top of the material receiving chamber 33 through the water pipe 481, and sprayed from the top of the material receiving chamber 33 into the built-in bin 331 by the nozzle 485. High-pressure water is sprayed to the top of the built-in bin 331 through the nozzle 485, and the surfaces of the plastic fragments floating on the water surface that are not in contact with the water are sprayed and cleaned, thereby solving the problem of poor cleaning effect of the plastic fragments floating on the water surface.

[0063] Since the impeller 482 extracts water from the cleaning box 40, and the water in the cleaning box 40 contains impurities after cleaning the plastic fragments, when filtering through the filter 484, it is easy to cause the mesh of the filter 484 to be clogged, and manual cleaning is required, which is time-consuming and labor-intensive.

[0064] The anti-blocking assembly includes: a scraper rod 4861 rotatably mounted on the filter screen 484, a guide groove 4862 provided on the inner wall of the water delivery pipe 481, one end of the scraper rod 4861 is slidably mounted in the guide groove 4862; the scraping end of the scraper rod 4861 abuts against the surface of the filter screen 484;

[0065] When the mesh of the filter screen 484 is blocked, the impeller 482 still rotates at a high speed. Due to the large-scale blockage of the holes 334 of the filter screen 484, negative pressure is generated in the water pipe 481, causing the compression spring 487 of the filter screen 484 to slide along the sliding groove 483 on the water pipe 481 toward the impeller 482. Since the scraper rod 4861 is rotatably installed on the surface of the filter screen 484, when the filter screen 484 slides, the scraper rod 4861 moves in the same direction as the filter screen 484. In addition, one end of the scraper rod 4861 is slidably installed in the guide groove 4862 on the inner wall of the water pipe 481, and the guide groove 4862 is spirally opened on the inner wall of the water pipe 481, when the scraper rod 4861 moves along the filter screen 484 to the impeller When the filter screen 484 slides in the direction of the impeller 482, the scraper rod 4861 is subjected to a force in the direction of the impeller 482 on the one hand, and is constrained by the guide groove 4862 on the other hand, so that the scraper rod 4861 rotates on the surface of the filter screen 484 while moving with the filter screen 484 in the direction of the impeller 482; thereby, the impurities blocked in the mesh of the filter screen 484 are scraped off, and the mesh on the filter screen 484 is now transparent, and the water in the cleaning box can flow through the mesh into the water pipe 481 again, and at the same time, the negative pressure in the water pipe 481 dissipates, and the spring 487 pushes the filter screen 484 to reset, so as to facilitate the next cleaning. Through the arrangement of the above-mentioned mechanism, the filter screen 484 can be cleaned automatically to reduce manual intervention, thus saving time and effort.
