Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead paste cleaning technology for lead-acid batteries, specifically a lead paste recycling device for pressure rollers. Background Technology
[0002] In the production of lead-acid battery electrode plates, pressure rollers are used to evenly coat the end faces of the electrode plates with lead paste. During this process, the pressure rollers effectively press the lead paste to ensure it bonds fully with the electrode plates. However, lead paste easily adheres to the pressure rollers during operation, which can affect the pressing effect and negatively impact the quality of the final electrode plates. Therefore, timely cleaning of the pressure rollers is essential to ensure smooth production, guarantee the overall performance and reliability of the electrode plates, reduce defect rates, and improve production efficiency. Currently, the main method for handling lead paste on the pressure rollers is scraping it off with a scraper. Large clumps of lead paste remaining on the pressure rollers are scraped directly onto the machine body, while smaller pieces adhere to the rollers, dry, and form dust that is dispersed into the air under the action of the scraper. This results in lead paste being difficult to recover, and the dispersed lead dust polluting the production environment and affecting the health of workers.
[0003] CN115301595A discloses a lead-acid battery pressure roller lead paste cleaning device, including a main body. An upper mounting box and a lower mounting box are connected to one side of the main body, with the lower mounting box located below the upper mounting box. Cleaning mechanisms are connected to the inner sides of both the upper and lower mounting boxes, and a residual material recycling mechanism is provided at the bottom of the lower mounting box. While the above patent can recover scraped-off residual lead paste to some extent through the upper and lower mounting boxes, it still requires regular manual collection of the recovered lead paste and cannot prevent dust from polluting the production environment.
[0004] Therefore, the technical problem to be solved in this case is: how to solve the problem of lead paste recovery in the cleaning roller. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a pressure roller lead paste recycling device. This pressure roller lead paste recycling device can directly recover large pieces of lead paste scraped off by the scraper through the collection box, thereby ensuring that the lead paste is pressed with sufficient flatness and stable quality. At the same time, the continuously circulating water in the collection box can absorb a small amount of dust generated in the scraped lead paste, reduce pollution, and ensure the safety of the production environment.
[0006] The technical solution of this utility model is:
[0007] A pressure roller lead paste recycling device includes a conveyor belt, a pressure roller and a scraper disposed above the conveyor belt, and a recycling unit. The recycling unit includes a support mounted on the conveyor belt, a collection box mounted on the support, and a water circulation module. The collection box, scraper, and pressure roller are arranged sequentially along the conveyor belt's conveying direction. The upper surface of the collection box is an open side. One end of the scraper contacts the pressure roller, and the other end of the scraper extends from the open side into the collection box. The collection box has an inlet and an outlet at both ends. The inlet and outlet are connected to the water circulation module, forming a circulating water flow within the collection box.
[0008] In the aforementioned roller lead paste recycling device, the scraper is arranged at an angle and gradually rises along the conveying direction of the conveyor belt.
[0009] In the aforementioned roller lead paste recycling device, the water circulation module includes a circulation pump and a water collection tank; the water collection tank is connected to the inlet and outlet of the collection box by pipes, and the circulation pump causes a circulating water flow to form in the collection box.
[0010] In the aforementioned roller lead paste recovery device, the water collection tank is equipped with a water inlet connected to an external water source and a sewage outlet connected to an external treatment device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0023] Example 1
[0024] refer to Figures 1-5 A pressure roller lead paste recycling device includes a conveyor belt 1, a pressure roller 2 and a scraper 3 disposed above the conveyor belt 1, and a recycling unit 4. The recycling unit 4 includes a support 41 disposed on the conveyor belt 1, a collection box 42 disposed on the support 41, and a water circulation module 43. The collection box 42, the scraper 3, and the pressure roller 2 are arranged sequentially along the conveying direction of the conveyor belt 1. The upper end face of the collection box 42 is an open side. One end of the scraper 3 contacts the pressure roller 2, and the other end of the scraper 3 extends from the open side into the collection box 42. The two ends of the collection box 42 are respectively provided with a water inlet 421 and a water outlet 422. The water inlet 421 and the water outlet 422 are respectively connected to the water circulation module 43, so as to form a circulating water flow in the collection box 42.
[0025] The lead paste recovery device of the pressure roller 2 in this embodiment can directly recover large pieces of lead paste scraped off by the scraper 3 through the collection box 42, thereby ensuring sufficient flatness and stable quality of the pressed lead paste. Simultaneously, the collection box 42 forms a continuously circulating water flow through the inlet 421 and outlet 422. The flowing water locally reduces the air pressure, adsorbing a small amount of dust from the surrounding air, thus adsorbing a small amount of dust generated from the scraped lead paste, thereby reducing pollution and ensuring a safe production environment. Furthermore, the water circulation device can directly collect the recovered lead paste, facilitating subsequent recycling processes.
[0026] In this embodiment, preferably, the scraper 3 is arranged at an angle and gradually rises along the conveying direction of the conveyor belt 1. In this preferred configuration, when the pressure roller 2 is driven by an external motor and rotates counterclockwise, since the scraper 3 is located at the front end of the pressure roller 2, the surface of the pressure roller 2 is cleaned by the scraper 3 before pressing the lead paste. Compared to the scraper 3 being located at the rear end of the pressure roller 2, the arrangement of the scraper 3 in this embodiment avoids the problem of the scraped lead paste accidentally falling onto the already pressed and flattened electrode plate, thus affecting the flatness. Simultaneously, as the inclined scraper 3 continuously scrapes off the residual lead paste on the pressure roller 2, the lead paste will fall from the upper surface of the scraper 3 into the collection box 42 under the action of gravity, thereby achieving the purpose of collection.
[0027] In this embodiment, more preferably, the bracket 41 is provided with a mounting post 411; the scraper 3 is detachably mounted on the mounting post 411. Specifically, the end of the mounting post 411 is provided with a top block 412 and a thread; after the scraper 3 passes through the mounting post 411, the two ends of the scraper 3 are pressed against the top block 412 and the thread by the mounting nut, thereby achieving detachable installation, which is convenient for workers to clean or replace the scraper 3.
[0028] Specifically, the water circulation module 43 includes a circulation pump 431 and a water collection tank 432; the water collection tank 432 is connected to the inlet 421 and outlet 422 of the collection box 42 by pipes, and the circulation pump 431 creates a circulating water flow in the collection box 42. More specifically, the circulation pump 431 continuously draws the solution from the water collection tank 432 into the collection box 42; preferably, to prevent the lead paste from being unable to drain smoothly, the inlet 421 is on the side of the collection box 42, while the outlet 422 is located on the bottom surface of the other side of the collection box 42.
[0029] More specifically, the water collection tank 432 is equipped with a water inlet 433 connected to an external water source and a drain outlet 434 connected to an external treatment device. In practical applications, after the solution in the water collection tank 432 circulates for a certain period of time, the drain outlet 434 is opened, and the solution and lead paste waste are pumped out to the external treatment device through an external pump, where it is then recycled back into lead using a hydrometallurgical process. Then, new solution is refilled into the water collection tank 432 through the water inlet 433.
[0030] In a preferred embodiment, to facilitate the cleaning of lead paste deposited in the water collection tank 432 due to prolonged use, a sealing cover 435 is provided on the upper surface of the water collection tank 432; the sealing cover 435 is provided with a handle 4351. In this way, workers can open the sealing cover 435 to directly clean its interior.
[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
