Abstract

The invention discloses a screening device after crushing and grinding waste roasting sagger for lithium battery anode materials. The screening device comprises a workbench, wherein support posts arefixedly connected to the bottom of the workbench, support rods are fixedly connected to the top of the workbench, a material conveying channel is fixedly connected to the tops of the support rods, a feed hopper is fixedly connected to one side of the material conveying channel, a suction fan and a dedusting box are fixedly connected to the top of the material conveying channel respectively, a non-woven filter screen and an activated carbon filter screen are respectively inserted into the dedusting box, and a motor is fixedly connected to the front surface of the material conveying channel. According to the screening device, a screening box, a piece of elastic cloth, a sieve plate, a vibrator, a telescopic sleeve rod, a first spring, a fixed block, a material conveying port and a sponge matare arranged, so that crushed materials can be screened, the crushed materials of small particle size fall in a collecting case, the crushed materials of large particle size enters a collecting box from the material conveying port, and the buffering and damping effects can be achieved by virtue of the telescopic sleeve rod and the first spring during screening.

Description

technical field [0001] The invention relates to the technical field of lightweight saggers, in particular to a screening device for crushing and grinding waste roasted saggers used for positive electrode materials of lithium batteries. Background technique [0002] At present, lithium battery cathode materials are calcined at high temperature by using saggers to carry materials. Generally, saggers are used to carry lithium carbonate and metal oxides (manganese, cobalt, nickel, etc.) for high-temperature reaction. Li2O reacts with acidic oxide silica and amphoteric oxide aluminum oxide in the surface layer of the sagger to produce a glassy substance, the main components of which are (LiAlO2, Li2OSiO2, Li4SiO4, LiAlSiO4, (LiCoO2)RR, Li24Mg0. 8 and SiO4, etc.), the average index of consumption of saggers at home and abroad is 200-300 kg per ton of positive electrode materials. Only in 2011, the production of positive electrode materials for lithium batteries in China consumed m...
