Recycling electric vehicle Li-Ion batteries plant

Power battery refers to a battery with large electric energy capacity and output power, which can be equipped with power supply for electric bicycles, electric vehicles, electric equipment and tools. With the vigorous development of new energy electric vehicles, the power battery market has shown a trend of rapid growth; at the same time, the amount of scrapped power batteries is increasing, and the recycling of scrapped power batteries has become an important factor affecting the development of the power battery industry.

Therefore, before recycling the copper and aluminum materials in waste batteries, it is necessary to carry out preliminary pre-treatment of waste batteries. The pre-treatment includes: 1) screening hard shell batteries and soft shell batteries, 2) fully crushing batteries, 3) purifying broken batteries 4) recycle the black powder in the battery.

A device and process for the pre-treatment of waste batteries, the device includes conveying equipment, crushers, dryers, waste gas treatment equipment and black powder recycling equipment, the conveying equipment includes a two-way conveyor that can change the conveying direction, and the two-way conveying The machine separates the hard-shell battery and the soft-shell battery, and transports them to different crushers for crushing, so that they can be differentiated according to the type of battery. For example, the hard-shell battery is preferably crushed with a double-shaft crusher first, and the soft-shell battery It is preferred to use a frequency conversion high-speed crusher for crushing treatment.

The waste gas treatment equipment includes spray tower, UV photolysis waste gas treatment equipment and a row of fans. The waste gas and waste liquid generated by the crusher and dryer pass through the pipeline in turn to spray the tower, UV photolysis waste gas treatment equipment and a row of fans, and discharge The exhaust gas is purified, and then discharged into the air after silencer treatment.

The copper and aluminum materials in the battery are crushed twice in the early stage of recycling, and the crushed battery is screened out by a cyclone collector to screen out the mixture of copper and aluminum particles and the waste gas containing the mixture of black powder. Under the action of pressure and suction, it enters the second cyclone collector, the exhaust end of the third crusher is connected to the second cyclone collector through pipelines, and the discharge end of the second cyclone collector recovers black powder, and the second cyclone collector The exhaust gas is purified through the bag filter, activated carbon adsorption tower and second exhaust fan in sequence.


What is the structure of the cutter shaft of the metal shredder?

The metal shredder is a new type of metal processing professional equipment with large-scale metal coarse crushing effect. It is mainly aimed at the shredding of some large-size scrap steel, color steel tiles, aluminum alloys, and aluminum profiles. The structure of the knife roller of this equipment is compared with that of The traditional metal crusher is quite special. The structure of the cutter shaft includes multiple main shafts and multiple cutter heads. There is a shaft hole in the middle of the cutter head. The discs are superimposed on the main shaft, and also include a moving knife seat, a moving knife, a static knife, a reducer, a workbench, and a main shaft, and seat grooves are symmetrically opened at both ends of the longitudinal and axial directions of each cutter disc. The movable knife seat is arranged in the seat groove, and the movable knife is connected to the movable knife seat and is arranged higher than the movable knife seat.

1. The structure of the knife roller of the metal shredder

The structure of the metal shredder knife roller has completely changed the traditional way of cleaning and crushing materials only by hammer crushers such as metal crushers. The convenient method of the structure processing department, due to the use of the claws to hold the material and the double-knife rollers to crush and cut each other, makes the processing and shredding of high-hardness materials easy and convenient. Compared with the impact effect of the metal crusher, the processing method of the shredder Easier and easier.

The knife roll structure of the double-shaft metal shredder includes a dynamic knife roll structure and a pure static knife roll structure. Both the first knife roll and the second knife roll materials are suitable for high-definition, high-hardness, and high-toughness alloy knives. The shredder The main shaft, the shaft sleeve and several moving knives on the main shaft complete the work together. The moving knives consist of nesting of several cutter bodies and shaft sleeves. Both sides of the claws contain protruding blades. With the above structure, the crushing High efficiency, long service life of knife roller, high production efficiency.

2. The tooth structure of the metal shredder

The main structure of the existing metal shredder is composed of a motor, a transmission belt, a large inertia knife roller and a blade on the knife roller, as shown in the figure below, the blade structure of the prior art adopts a multi-knife tooth shape, and the specific knife tooth structure includes 3 teeth, 5 teeth, 8 teeth, 24 teeth, etc. These toothed blades are set on the cutter shaft. When the double cutter shafts roll in opposite directions, the cutter tooth structure will block the metal material, and the material will be torn and squeezed under multiple actions It is cut and finally cut by the high torque of the double cutter shaft to form a metal block with uniform shape and size, which increases the material density and makes the shredded material easy to transport. On the other hand, after the material is shredded, it can also be The further fine crushing treatment is carried out by the metal crusher, which is convenient for further material sorting, impurity removal and paint removal treatment, and reduces the difficulty of material smelting.

At present, the recycling and crushing of many large-volume waste metals, color steel tiles, aluminum profiles and other materials need to be mechanically shredded or crushed by metal shredders, so that waste materials can be dismantled, and the crushing efficiency is improved. High, low equipment operating speed, low noise, large shredding torque, high strength and wear-resistant knives for internal use, the moving knife of the knife roller and the fixed knife cooperate, and the shearing force on the material during the transmission process is fully absorbed by the knife shaft and the moving and static knives. Absorption, the metal shredder works stably, the equipment has a long service life, and the replacement of the knife roller is simple and convenient. It is one of the excellent scrap metal processing equipment.
