The device comprises a damping type crushing and screening device and an iron removing and discharging device, wherein the damping type crushing and screening device comprises a motor, a crushing box, two damping devices and a screening board; the two damping devices are welded on two sides of the upper side of a protective sleeve; the crushing box is welded above two fixing boxes; the motor is fixedly arranged on the left side of the upper side of the crushing box; the screening board is fixedly arranged on a first spring and a second spring; the iron removing and discharging device comprises a magnetic eraser, a plurality of electromagnetic coils and a uniform water distribution tank; the plurality of electromagnetic coils are fixedly arranged on two sides of an iron removing box; the magnetic eraser is fixedly arranged above the left side of the iron removing box; the water distribution tank is welded on the upper side in the iron removing box. The device integrates crushing and iron removing functions and is high in practicability, the crushing effect and the service life of the device are guaranteed by means of the damping devices, meanwhile, the device is convenient to clean, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a lithium battery material processing device, in particular to a shock absorption type lithium battery material crushing, screening and iron removal device. Background technique [0002] In the production process of lithium batteries, lithium battery materials need to undergo operations such as pulverization, iron removal, screening and mixing to ensure quality, so as to be used for production. Generally, pulverization and iron removal are carried out separately. The particles are not completely up to the standard and need to be screened. During the crushing and screening, the device will vibrate, which will affect the crushing effect and the service life of the entire device; and now, when the iron removal equipment is removing iron, the slurry or dry powder raw materials are input from the feed port. The inner cylinder is output from the discharge port after passing through the soft magnetic net. The magnetic field generated ...

Problems solved by technology

[0002] In the production process of lithium batteries, lithium battery materials need to be pulverized, iron removed, sieved, stirred and mixed to ensure quality so that they can be used for production. Generally, crushing and iron removal are carried out separately. When crushing, the crushed Particles are not fully up to the standard and need to be screened. While crushing and screening, the device will vibrate, affecting the crushing effect and the service life of the entire device; and now when the iron removal equipment is removing iron, the slurry or dry powder raw materials are input from the feed port The inner cylinder is output from the discharge port after passing through the soft magnetic net. The magnetic field generated by the electromagnetic coil will magnetize the soft magnetic net, so that the soft magnetic net has a strong magnetic field. When the dry powder or slurry passes through the soft magnetic net, the iron in the dry powder or slurry will The magnetic substance will be adsorbed on the soft magnetic net to achieve the purpose of removing the ferromagnetic substance in the raw material; however, when there is too much ferromagnetic slag adsorbed on the soft magnetic net, it is easy to cause blockage, so the soft magnetic net needs to be cleaned regularly to remove the slag on the soft magnetic net During the cleaning process of the soft magnetic net, although the power supply of the electromagnetic coil has been disconnected, the magnetic field of the soft magnetic net basically disappears, but the ferromagnetic slag adsorbed on the soft magnetic net will still have hysteresis. The hysteresis can also be adsorbed on the soft magnetic net, which is not easy to clean
