Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE waste recycling and treatment technology, specifically a PE waste recycling and cleaning device. Background Technology
[0002] In the production of plastic products, common PE wastes such as plastic bags, plastic films, water pipes, and wire sleeves can be reprocessed into various plastic products. At the same time, by recycling PE waste, it is necessary to use a cleaning device to clean the PE waste before reprocessing it.
[0003] Existing cleaning devices typically involve directly pouring simply crushed waste into the cleaning tank for processing. However, considering the large amount of impurities contained in the waste, subsequent simple cleaning may not be able to effectively remove the stubborn dirt adhering to the waste, reducing the cleaning efficiency of the equipment during actual operation. Therefore, a PE waste recycling and cleaning device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a PE waste recycling and cleaning device to solve the problem of low cleaning efficiency in existing cleaning devices mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

A pretreatment guide frame is fixedly installed at the upper left position of the cleaning tank body. A metal mesh frame is provided inside the pretreatment guide frame. Columns are fixedly connected to the left and right sides of the bottom of the metal mesh frame. The bottom of each column is engaged with a support set inside the pretreatment guide frame. An inner support rod is provided between the two supports. A rotating cylinder is provided in the concave part of the metal mesh frame. A drive shaft that is rotatably connected to the pretreatment guide frame is fixedly connected to the front and rear ends of the rotating cylinder. A metal rubbing brush is provided outside the rotating cylinder. A drive shaft extending to the outside of the pretreatment guide frame is rotatably connected to the upper middle position inside the pretreatment guide frame. A gear is fixedly connected to the front end of the drive shaft.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution:
[0019] A PE waste recycling and cleaning device includes a cleaning tank body 1, a conveying bottom frame 2 connected to the bottom of the cleaning tank body 1, a pretreatment guide frame 4 fixedly installed at the upper left position of the cleaning tank body 1, a metal mesh frame 5 inside the pretreatment guide frame 4, columns 6 fixedly connected to the left and right sides of the bottom of the metal mesh frame 5 respectively, a support 7 set inside the pretreatment guide frame 4 being engaged at the bottom of the columns 6, an inner support rod 8 between the two supports 7, a rotating cylinder 9 in the concave part of the metal mesh frame 5, a drive shaft 11 fixedly connected to the front and rear ends of the rotating cylinder 9 and rotatably connected to the pretreatment guide frame 4, a metal rubbing brush 10 outside the rotating cylinder 9, a drive shaft 12 extending to the outside of the pretreatment guide frame 4 rotatably connected to the upper middle position inside the pretreatment guide frame 4, and a gear 13 fixedly connected to the front end of the drive shaft 12.
[0020] like Figure 1 and Figure 3 As shown, the conveyor base frame 2 is arranged in an inclined structure. A drive motor 20 with its output end extending into the conveyor base frame 2 is installed at the lower left position of the conveyor base frame 2. Since the output end of the drive motor 20 extends into the conveyor base frame 2 and is connected to the spiral conveying shaft inside the conveyor base frame 2, this structure facilitates the spiral conveying of the cleaned PE waste material outward by the entire device. A discharge hopper 18, which is connected to the conveyor base frame 2, is fixedly connected to the center of the right side of the washing tank body 1. A discharge port is connected to the upper part of the discharge hopper 18. The guide trough 19 and the left and right sides of the washing tank body 1 are respectively fixedly connected to the side uprights 3. With the interconnection, the PE waste gradually conveyed to the upper right position of the device will be pushed upward and outward in a gradually upward manner. The metal mesh frame 5 has a "V" shaped structure. The bottom of the metal mesh frame 5 and the top of the inner support rod 8 are set to abut against each other. When the PE waste is put into the pretreatment guide frame 4, the metal mesh frame 5 will screen the PE waste. At the same time, the inner support rod 8 will also provide support to the metal mesh frame 5.
[0021] like Figure 1 , Figure 2 and Figure 3As shown, the metal rubbing brush 10 and the screen surface of the metal mesh frame 5 are in contact. The metal rubbing brush 10 is set on the vertical central axis of the metal mesh frame 5. The front end of the pretreatment guide frame 4 is fixedly connected to a limiting frame 14. An electric push rod 16 is fixedly installed inside the limiting frame 14. The movable end of the electric push rod 16 is fixedly connected to a limiting slider 17 that is slidably connected to the limiting frame 14. A rack 15 that is slidably connected to the top of the limiting frame 14 is fixedly connected to the upper left of the limiting slider 17. The rack 15 and the gear 13 are meshed. When the electric push rod 16 reciprocates, the rack 15 will reciprocate horizontally under the action of the limiting slider 17, and will also reciprocate forward and reverse rotation with the gear 13.
[0022] Workflow: The electrical energy required for the device to start and operate in this utility model comes from an external power source. Before use, the entire device can be moved to the PE waste recycling line so that the discharge port of the crushing equipment can be connected to the inlet of the pretreatment guide frame 4. During the recycling process of PE waste, when it is necessary to clean the PE waste brought out from the previous crushing equipment, the PE waste is fed into the pretreatment guide frame 4 and falls onto the metal mesh frame 5 for screening. Since some of the screened PE waste with stubborn dirt is relatively large, it is not easy to fall through the screen holes on the metal mesh frame 5. First, the electric push rod 16 is activated to reciprocate and stretch, so that the limiting slider 17 moves horizontally along the inside of the limiting frame 14 with the rack 15, so that the gear 13 is driven, and through the drive shaft 12 and the transmission shaft 11, the rotating drum 9 and the metal rubbing brush 1 are driven. The device rotates in both directions to repeatedly rub the stubborn PE waste that has fallen onto the metal mesh frame 5 after being screened out. This allows the stubborn dirt on the PE waste to be pre-rubbed off and separated, enabling the device to perform more efficient cleaning operations later. The PE waste that has been rubbed and separated from the dirt will then fall into the cleaning tank body 1. At this time, while the entire device uses the liquid pre-injected into the cleaning tank body 1 to clean the PE waste, the spiral conveyor shaft installed inside the conveyor bottom frame 2 will provide spiral auxiliary conveying for the PE waste that has fallen into the lower part of the cleaning tank body 1 while the drive motor 20 is running. This allows the cleaned PE waste to be gradually conveyed out through the discharge hopper 18 and the discharge guide chute 19, thus completing the entire cleaning work. The above cleaning technology is a publicly disclosed prior art.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
