Description

Technical Field

[0001] The invention relates to the technical field of waste plastic cleaning, and in particular to cleaning equipment for recycling waste plastic. Background Art

[0002] Plastic recycling refers to the use of a certain recycling process to recycle waste plastics for reuse, and to achieve the purpose of turning waste into treasure. After recycling waste plastics, they generally need to be cleaned to provide clean raw materials for subsequent melting, granulation and other processes. The recycled plastic particles produced in this way are of higher quality and easier to be processed into various plastic products, thus realizing the recycling of waste plastics.

[0003] A Chinese patent with authorization announcement number CN111359966B discloses a continuous washing machine for waste plastic fragments, including a main body and a waste plastic fragment conveying system arranged inside the main body and cooperating with the main body. A high-pressure water spraying system is provided on one side of the waste plastic fragment conveying system. The bottom end of the waste plastic fragment conveying system includes a conveyor belt and plastic fragment scrapers distributed on the conveyor belt. The waste plastic fragments are scraped up and conveyed by the cooperation of the conveyor belt and the scraper. During the conveying process, the waste plastic fragments are washed by the high-pressure water spraying system.

[0004] The shortcomings of the above-mentioned prior art solution are: although the above-mentioned solution relies on the conveyor belt to drive the scraper to scrape up the broken plastic sheets put into the cleaning equipment one by one, and then transport them through the location of the spray washing system, and spray washing is achieved through the spray washing system, but in the process of the conveyor belt scraping up the broken plastic sheets through the scraper for transportation, the broken plastic sheets between each adjacent scraper do not move relative to the conveyor belt. In particular, when the plastic sheets on the conveyor belt are stacked to a certain extent, it is difficult to fully rinse the plastic sheets transported on the conveyor belt by relying solely on the spray washing system set in a fixed position, resulting in an insufficient cleaning effect. Multiple cleanings may be required, which in turn reduces the cleaning efficiency. Summary of the invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention conveys the broken plastics that fall into the cleaning box through a conveyor belt. During the conveying process, the transmission column that drives the conveyor belt relies on the action of the convex rod to link the baffle, so that the lifting support plate arranged on the inner circle of the conveyor belt can continuously lift and lower the elastic conveying net on the conveyor belt with the curved surface nozzle, so that the plastic on the elastic conveying net can be turned over.

[0021] 2. In the present invention, whenever the lifting support plate drives the curved surface nozzle to lift up the elastic conveying net, the connecting pipe connected to the curved surface nozzle drives the blocking ball to separate from the dividing ring in the auxiliary water pipe, thereby connecting the connecting pipe with the auxiliary water pipe to facilitate water supply and flushing. When the lifting support plate drives the curved surface nozzle to descend, the connecting pipe brings the blocking ball to hit the dividing ring in the auxiliary water pipe, blocking the water flow from continuing to be transported, thereby preventing the curved surface nozzle from continuing to spray water when it is separated from the plastic on the elastic conveying net, causing unnecessary loss of cleaning water.

[0022] 3. When the transmission column of the present invention drives the conveyor belt to run, the transmission column also drives the rotary flushing nozzle to rotate through the transmission wheel and the transmission belt. During the rotation of the rotary flushing nozzle, its flushing angle will change, which is convenient for preliminary flushing of the plastic sliding down the feed inclined guide plate, and at the same time, it can also flush the plastic transported on the conveyor belt, thereby improving the cleaning efficiency, and there is no need to drive the rotary flushing nozzle to rotate separately.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 6 As shown, a cleaning device for recycling waste plastics is used to clean plastics that have undergone preliminary crushing treatment, including a cleaning box 1, a feed inclined guide plate 2 and a discharge inclined guide plate 4. The feed inclined guide plate 2 is fixedly arranged on one side of the cleaning box 1, and the discharge inclined guide plate 4 is fixedly arranged on the other side of the cleaning box 1. The feed inclined guide plate 2 is used to guide the plastic fragments to enter the cleaning box 1, and the discharge inclined guide plate 4 is used to guide the cleaned plastic fragments to slide out of the cleaning box 1 and slide to the next processing step. A filter plate 6 is fixedly arranged at the middle position inside the cleaning box 1. The filter plate 6 is used to separate the inside of the cleaning box 1 into a cleaning area and a water source area. The cleaning area is located at the top and the water source area is located at the bottom. Wastewater in the cleaning process of the cleaning area can enter the water source area after being filtered by the filter plate 6, so as to facilitate recycling; a belt transmission component is arranged above the filter plate 6 for conveying the plastics falling on the filter plate 6 to the discharge inclined guide plate 4; the cleaning device also includes an elastic conveying net 23, a lifting and flushing mechanism and a rotating flushing nozzle;

[0033] There are multiple elastic conveying nets 23, which are evenly distributed on the belt transmission assembly. The elastic conveying nets 23 are used to support plastics. The lifting and flushing mechanism lifts and pushes the elastic conveying net 23 to stretch and deform, so that the plastic parts on the elastic conveying net 23 can be turned over, and the plastic parts on the elastic conveying net 23 can be flushed at a close distance, so as to improve the cleaning effect.

[0034] The rotary flushing nozzle is arranged on one side of the feed inclined guide plate 2, and is used to flush the feed inclined guide plate 2 and the plastic parts on the belt transmission assembly. The belt transmission assembly drives the lifting and flushing mechanism to lift and lower and the rotary flushing nozzle to rotate.

[0035] In some specific embodiments, in combination Figure 1 and Figure 2 As shown, the belt transmission assembly includes a transmission column 13, a conveyor belt 14 and a push scraper 15. Two transmission columns 13 are provided and are rotatably arranged on both sides of the interior of the cleaning box 1, and the two transmission columns 13 have different height positions. One transmission column 13 is close to the filter plate 6 and is in a lower position, and the other transmission column 13 is far away from the filter plate 6 and is in a higher position. One of the transmission columns 13 is driven to rotate by a motor, and the conveyor belt 14 is connected between the two transmission columns 13. The elastic conveying net 23 is evenly distributed on the conveyor belt 14. There are multiple push scrapers 15, which are evenly distributed along the conveyor belt 14. The push scraper 15 is perpendicular to the conveying surface of the conveyor belt 14. Each elastic conveying net 23 is between two push scrapers 15. The side of the filter plate 6 close to the feed inclined guide plate 2 is an arc-shaped mesh plate 7, and the arc-shaped mesh plate 7 cooperates with the push scraper 15 along the trajectory of the conveyor belt 14 rotating around the transmission column 13.

[0036] When the plastic fragments slide into the cleaning box 1 through the feed inclined guide plate 2, they fall on the arc-shaped mesh plate 7, and the transmission column 13 drives the conveyor belt 14 to rotate clockwise, so that the pushing scrapers 15 distributed on the conveyor belt 14 pass through the position of the arc-shaped mesh plate 7 piece by piece, so as to scrape up the broken plastics falling on the arc-shaped mesh plate 7 and push them. When the plastic is finally transported to the position of the higher transmission column 13, it slides through the corner position and falls on the discharge inclined guide plate 4, and slides to the processing position of the next process, realizing the plastic transportation and transfer.

[0037] In some specific embodiments, such as Figure 2 As shown, the lifting flushing mechanism includes a lifting support plate 18, a curved surface nozzle 20 and a main water pipe 16. The lifting support plate 18 is located between the two transmission columns 13. A lifting transmission mechanism is connected between the lifting support plate 18 and the transmission column 13. The main water pipe 16 is arranged in parallel below the lifting support plate 18. A guide rod 21 that vertically penetrates the lifting support plate 18 is fixedly connected to the outer wall of the main water pipe 16. Two guide rods 21 are arranged in pairs. The lifting support plate 18 can slide up and down relative to the guide rods 21, and a stretchable spring 22 is connected between the lifting support plate 18 and the guide rods 21. A plurality of curved surface nozzles 20 are arranged and are equidistantly distributed above the lifting support plate 18. The upper surface of the curved surface nozzle 20 is a convex curved surface, and There are spray holes evenly distributed, and a connecting pipe 19 is fixedly connected to the bottom of each curved surface nozzle 20, and the connecting pipe 19 passes through the lifting support plate 18 and is fixed in position relative to the lifting support plate 18. A plurality of auxiliary water pipes 17 corresponding to the connecting pipe 19 are evenly distributed on the main water pipe 16, and each connecting pipe 19 is slidably inserted in the auxiliary water pipe 17, and an opening and closing structure is cooperated and connected between each connecting pipe 19 and the corresponding auxiliary water pipe 17. The auxiliary water pipe 17, the connecting pipe 19 and the curved surface nozzle 20 are connected to each other when the opening and closing structure is in an open state. Whenever the connecting pipe 19 rises relative to the auxiliary water pipe 17, the opening and closing structure is opened, and when the connecting pipe 19 descends and is inserted into the bottom of the auxiliary water pipe 17, the opening and closing structure is closed.

[0038] Among them, Figure 5 and Figure 6 As shown, the lifting transmission mechanism includes a linkage baffle 27 and a convex rod 28. The linkage baffle 27 is fixedly connected to the lifting support plate 18. In order to avoid occupying the internal space of the cleaning box 1, the linkage baffle 27 can be set outside the cleaning box 1, and then a strip-shaped opening 24 is opened on the side wall of the cleaning box 1, and then the lifting support plate 18 is fixedly connected to the linkage baffle 27 through a bracket passing through the strip opening 24, and four linkage baffles 27 are preferably arranged, and each end of the transmission column 13 corresponds to a linkage baffle 27, and the rotating end of each transmission column 13 is fixedly connected with a convex rod 28 corresponding to the linkage baffle 27, and the convex rod 28 is eccentrically located away from the end of the transmission column 13, and the linkage baffle 27 is on the rotation trajectory of the convex rod 28 away from the end of the transmission column 13.

[0039] When the transmission column 13 rotates clockwise, it drives the convex rod 28 to rotate synchronously. Whenever the convex rod 28 rotates to the position of the linkage baffle 27, the end of the convex rod 28 pushes the linkage baffle 27 upward, so that the linkage baffle 27 drives the lifting support plate 18 to rise relative to the guide rod 21, and the spring 22 is in a stretched state during this process, and the lifting support plate 18 drives the distributed curved surface spray heads 20 and the corresponding connecting pipes 19 to rise, and the curved surface spray heads 20 push the passing elastic conveying net 23 from bottom to top, so that the elastic conveying net 2 3 is stretched and deformed upward, so that the broken plastics on the elastic conveying net 23 are turned over, and the broken plastics are distributed to both sides of the raised curved surface nozzle 20; the curved surface nozzle 20 can directly wash the broken plastics at a close distance, and due to the convex curved surface of the curved surface nozzle 20, the distributed spray holes can wash the broken plastics from multiple angles, thereby ensuring the cleaning effect. Whenever the convex rod 28 rotates out of the linkage baffle 27, the lifting support plate 18 is reset by the rebound force of the spring 22, thereby driving the curved surface nozzle 20 and the connecting pipe 19 to descend and reset.

[0040] It should be noted that the main water pipe 16 is connected to the water source area in the cleaning box 1, so as to continuously supply water of a certain pressure to each auxiliary water pipe 17. Whenever the curved nozzle 20 and the connecting pipe 19 are raised relative to the auxiliary water pipe 17, the opening and closing structure is opened to facilitate the flow of water into the curved nozzle 20 and then spray out. Whenever the connecting pipe 19 is lowered and reset, the opening and closing structure is closed to prevent the curved nozzle 20 from continuously spraying water when it is separated from the elastic conveying net 23, and failing to act on the plastic, causing unnecessary loss of water source.

[0041] In some specific embodiments, in combination Figure 3 and Figure 4 As shown, the opening and closing structure includes a separating ring 25 and a sealing ball 26. The separating ring 25 is fixedly connected to the inner bottom of the secondary water pipe 17. The sealing ball 26 is fixedly connected to the end of the connecting pipe 19 away from the curved nozzle 20 through a bracket. The ball diameter of the sealing ball 26 is smaller than the inner diameter of the connecting pipe 19 and larger than the inner diameter of the separating ring 25. When the connecting pipe 19 drops to the corresponding position relative to the secondary water pipe 17, the sealing ball 26 hits the inner circle position of the separating ring 25 to block it. In this way, the water transmitted by the main water pipe 16 cannot enter the connecting pipe 19. Only when the connecting pipe 19 rises relative to the secondary water pipe 17 can the connection be achieved.

[0042] In some specific embodiments, in combination Figure 1 and Figure 5As shown, the rotary flushing nozzle includes a drum 10, a nozzle 11 and a transmission belt 31. The drum 10 is horizontally rotated and connected inside the cleaning box 1 and is close to the feed inclined guide plate 2. A plurality of nozzles 11 are provided and are evenly distributed on the drum 10. A water pipe 29 is inserted at one end of the drum 10, and the drum 10 rotates around the water pipe 29. A transmission wheel 30 is coaxially fixedly connected to the end of the drum 10 away from the water pipe 29 and one of the transmission columns 13. The transmission belt 31 is connected between the two transmission wheels 30. During the rotation of the transmission column 13, the drum 10 is driven to rotate through the transmission wheel 30 and the transmission belt 31. At the same time, the water pipe 29 transports water into the drum 10, so that the rotating drum 10 can spray clean water through the distributed nozzles 11, and the plastic sheets on the feed inclined guide plate 2 and the conveyor belt 14 can be flushed. In addition, the angle of the nozzle 11 changes during the rotation, which is convenient for flushing the plastic sheets from multiple angles.

[0043] It should be noted that a curved baffle 12 is fixedly connected to the inner wall of the cleaning box 1, and the curved baffle 12 is used to block the nozzles 11 distributed on the side walls of the upper half of the drum 10. When each nozzle 11 rotates with the drum 10 to the position of the curved baffle 12, the port of each nozzle 11 just fits against the side wall of the curved baffle 12 and is blocked to prevent water from spraying upward. It should be noted that when the port of the nozzle 11 fits against the side wall of the curved baffle 12, relative sliding may also occur.

[0044] In some specific embodiments, a first water pump 5 is installed on one side of the bottom of the cleaning box 1, and the water pipe 29 and the main water pipe 16 are connected to the output end of the first water pump 5 through an extension pipe. The first water pump 5 is used to pump water from the water source area inside the cleaning box 1 and transport it to the water pipe 29 and the main water pipe 16 to facilitate the recycling of water.

[0045] In some specific embodiments, a second water pump 8 is fixedly installed on the other side of the cleaning box 1, and the output end of the second water pump 8 is connected to the water source area inside the cleaning box 1. The second water pump 8 is connected to an external water source. A water level sensor 9 is installed on the side wall of the water source area inside the cleaning box 1. The water level sensor 9 can be connected to an alarm. During the cleaning process, the transported broken plastics will inevitably take away some water, which will naturally cause water loss. In this way, the water in the water source area will continue to decrease. Even if it is recycled, when the water level drops to a certain level, the water level sensor 9 is used to detect feedback, and then the second water pump 8 is controlled to start, and the external water source is transported to the cleaning box 1 for replenishment.

[0046] In some specific embodiments, the feed inclined guide plate 2 is an elastic metal plate, and a vibrator 3 is fixedly installed on the outer wall of the feed inclined guide plate 2. The vibrator 3 is started to generate vibration, so that the feed inclined guide plate 2 is moved.

[0047] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0048] First, the preliminarily crushed plastic is poured into the cleaning box 1 through the feed inclined guide plate 2 and falls on the arc-shaped mesh plate 7. During this process, the transmission column 13 drives the conveyor belt 14 to rotate clockwise, so that the pushing scraper 15 distributed on the conveyor belt 14 passes through the position of the arc-shaped mesh plate 7 piece by piece, which is convenient for scraping up the broken plastic falling on the arc-shaped mesh plate 7 and pushing it, and the conveyor belt 14 is used to realize transportation.

[0049] The first water pump 5 delivers clean water in the water source area in the cleaning box 1 to the water delivery pipe 29 and the main water pipe 16 . The water in the water delivery pipe 29 enters the rotating drum 10 and is then sprayed out through the spray pipe 11 .

[0050] And during the rotation of the transmission column 13, it drives the rotating drum 10 to rotate through the transmission wheel 30 and the transmission belt 31, so that the rotating rotating drum 10 can spray clean water through the distributed nozzles 11, so as to wash the plastics on the feed inclined guide plate 2 and the conveyor belt 14, and the angle of the nozzle 11 changes during the rotation, so as to facilitate the washing of the plastic sheets from multiple angles.

[0051] At the same time, as the transmission column 13 rotates clockwise, it also drives the convex rod 28 to rotate synchronously. Whenever the convex rod 28 rotates to the position of the linkage baffle 27, the end of the convex rod 28 pushes the linkage baffle 27 upward, so that the linkage baffle 27 drives the lifting support plate 18 to rise relative to the guide rod 21, and the spring 22 is in a stretched state during this process. Then the lifting support plate 18 drives the distributed curved surface spray heads 20 and the corresponding connecting pipes 19 to rise, and the curved surface spray heads 20 push the passing elastic conveying net 23 from bottom to top, so that the elastic conveying net 23 is stretched and deformed upward, so that the broken plastics on the elastic conveying net 23 are turned over, and the broken plastics are distributed to both sides of the raised curved surface spray heads 20; the curved surface spray heads 20 can directly wash the broken plastics at a close distance. , and due to the convex curved surface of the curved nozzle 20, the distributed spray holes are convenient for washing the broken plastics from multiple angles, thereby ensuring the cleaning effect. Whenever the convex rod 28 rotates to disengage from the linkage baffle 27, the lifting support plate 18 is reset by the rebound force of the spring 22, thereby driving the curved nozzle 20 and the connecting pipe 19 to descend and reset; when the connecting pipe 19 descends to the corresponding position relative to the auxiliary water pipe 17, the blocking ball 26 contacts the inner circle position of the separation ring 25 to block it, so that the water transmitted by the main water pipe 16 cannot enter the connecting pipe 19. Only when the connecting pipe 19 rises relative to the auxiliary water pipe 17 can the connection be achieved, thereby preventing the curved nozzle 20 from continuously spraying water when it is separated from the elastic conveying net 23, and failing to act on the plastic, causing unnecessary loss of water source.

[0052] Finally, the conveyor belt 14 transports the plastic to the position of the higher transmission column 13, and then slides through the corner position, just falling on the discharge inclined guide plate 4, and slides to the processing position of the next process, realizing the plastic transportation and transfer.

[0053] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
