Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead-containing waste recycling technology, and more specifically, to a magnetic separation combined with impurity removal device for lead-containing waste. Background Technology
[0002] Lead-containing waste refers to solid waste containing metallic lead or its compounds generated during production, daily life, or other activities. In particular, the waste from the recycling of lead-acid batteries often contains a large amount of lead-containing waste. In order to recycle and utilize the lead resources in the waste, it is often necessary to pre-treat the lead-containing waste to remove impurities. However, since lead-containing waste contains not only non-magnetic impurities such as plastics, copper, and zinc, but also magnetic impurities such as iron, nickel, and cobalt, it is necessary to use a magnetic separation combined with impurity removal device to achieve the pre-treatment of lead-containing waste to remove impurities.
[0003] Traditional magnetic separators for lead-containing waste can only remove magnetic impurities such as iron, nickel, and cobalt from lead-containing waste. However, they cannot simultaneously remove lightweight impurities such as plastics and wood chips, as well as non-magnetic impurities such as copper and zinc. This requires multiple transfers of lead-containing waste for separate removal, which not only increases the difficulty and labor intensity of workers but also reduces the efficiency of lead-containing waste treatment, making them relatively impractical. Therefore, those skilled in the art have proposed a combined magnetic separator for removing impurities from lead-containing waste. Utility Model Content

A second guide hopper is welded to the bottom of the inner cavity of the air separator, and a second discharge pipe is connected to the bottom of the inner cavity of the second guide hopper.
[0009] Furthermore, a door is installed on one side of the collection box via a hinge, and a handle is fixedly installed on the door.

[0011] Furthermore, the crushing shaft on one side and the conveying shaft on the other side are located on the same vertical plane.
[0012] Compared with the prior art, this utility model provides a magnetic separation and impurity removal device for lead-containing waste, which has the following beneficial effects: (1) This utility model is provided with a mounting base plate, a crushing box and a magnetic separator. A support frame is welded to the top surface of the mounting base plate, and a magnetic separator is welded to the top of the support frame. A crushing box is welded to one side of the top surface of the magnetic separator. A feed hopper is welded to the top surface of the crushing box. Crushing shafts are symmetrically installed in the inner cavity of the crushing box, and crushing rollers are fixedly installed on the crushing shafts. Transmission gears are symmetrically fixedly installed at one end of the two crushing shafts, and the two transmission gears mesh with each other. A servo motor is bolted to the side wall of the crushing box, and the output end of the servo motor is keyed to one end of the crushing shaft. The inner cavity of the magnetic separator is equipped with... There are two conveyor shafts. A conveyor roller is fixedly installed on one conveyor shaft, and a permanent magnet roller is fixedly installed on the other conveyor shaft. A conveyor belt is connected between the conveyor roller and the permanent magnet roller. In use, the worker feeds the lead-containing waste into the crushing chamber through the feed hopper. At the same time, the servo motor is started through the control panel to drive one of the crushing shafts to rotate. Under the transmission of two gears, the two crushing rollers rotate relative to each other, thus crushing the lead-containing waste falling into the crushing chamber to make the waste into uniform particle size, so as to improve the subsequent impurity removal effect. The bottom surface of the crushing chamber and the top surface of the magnetic separator are respectively opened with the first... The crushing chamber has a connecting port, and a first guide hopper is fixedly installed on the bottom surface of the crushing chamber. Therefore, the crushed lead-containing waste can fall onto the conveyor belt. On the other hand, a first pulley is fixedly installed at one end of one crushing shaft, and a second pulley is fixedly installed at one end of one conveyor shaft. A transmission belt is connected between the first and second pulleys. Therefore, when the crushing shaft rotates, it drives the conveyor shaft to rotate, which in turn drives the conveyor belt to rotate around the conveyor roller and the permanent magnet roller. When the lead-containing waste rotates to the permanent magnet roller, the magnetic impurities such as iron, cobalt, and nickel are adsorbed. Other lead-containing waste is thrown into the receiving hopper cavity under inertia. The magnetic separator is located at the bottom of the receiving hopper cavity. A receiving box is fixedly installed on the surface to collect falling magnetic impurities. Several scraper plates are evenly welded to the inner wall of the receiving box to scrape off some of the magnetic impurities remaining on the conveyor belt, allowing them to fall fully into the inner cavity of the receiving box. A guide plate is fixedly installed in the inner cavity of the receiving box, allowing the magnetic impurities to be conveyed along the guide plate to the first discharge pipe for discharge. A placement rack is welded to the bottom of the magnetic separator, and the placement rack holds the receiving box for collecting the sorted magnetic impurities. This allows the crushing and magnetic separation of lead-containing waste to be completed using only one servo motor, making it more convenient and practical.
[0013] (2) This utility model is equipped with an air classifier and a mineral processing shaking table. A second connecting port is opened on one side of the bottom surface of the magnetic classifier, and the second connecting port is connected to the bottom of the inner cavity of the receiving hopper. An air classifier is welded to the bottom surface of the magnetic classifier. A gas equalization box is bolted to the inner wall of the air classifier, and several air classifier nozzles are evenly connected to the gas equalization box. An air classifier fan is bolted to the outer wall of the air classifier, and one end of the air classifier fan is connected to the output end of the air classifier fan, and the other end of the air classifier fan is connected to the inner cavity of the gas equalization box. A collection box is welded to the side wall of the air classifier, and an air classifier outlet is opened between the collection box and the air classifier. When the lead-containing waste with magnetic impurities removed falls into the inner cavity of the air classifier, the control panel starts the air classifier fan to deliver air to the inner cavity of the gas equalization box through the air delivery pipe, and finally sprays it out through the air classifier nozzles. The constant air volume is used to air classify and remove light impurities such as plastic and wood chips in the lead-containing waste. The selected impurities fall into the inner cavity of the collection box through the air separation outlet for collection. A door with a handle is installed on one side of the collection box via a hinge, facilitating the removal and cleaning of the collected impurities. A mineral processing shaking table is bolted to the mounting base. A second guide hopper is fixed to the bottom of the inner cavity of the air separation box, and a second discharge pipe is connected to the bottom of the second guide hopper. The lead-containing waste, after impurities have been removed, falls onto the mineral processing shaking table through the second discharge pipe. Gravity separation on the shaking table removes copper and zinc impurities from the remaining lead-containing waste, resulting in waste with a high lead content for subsequent recycling. This combined magnetic separation and impurity removal device for lead-containing waste achieves integrated impurity removal treatment of crushing, magnetic separation, air separation, and gravity separation, resulting in higher impurity removal efficiency, greater work efficiency, and stronger practicality.

The constant air volume is used to air separate and remove light impurities such as plastic and wood chips in the lead-containing waste. The screened impurities fall into the inner cavity of the collection box 23 through the air separation outlet 22.
