Small-batch permanent magnet iron removal device for laboratory

Abstract

The invention discloses a small-batch permanent magnet iron removal device for a laboratory. The small-batch permanent magnet iron removal device comprises a motor and a speed reducer which are connected in sequence, wherein an output end of the speed reducer is provided with two output shafts, the first output shaft is fixed in a first support, and the second output shaft is connected with a first gear; a left end of the rotating shell is fixed to the first support, a right end of the rotating shell is fixed to the second support, and the rotating shell and the second gear are integrated and connected with the first gear through the second gear; a plurality of sleeves are arranged in the rotary shell, one end of each sleeve is fixed to a sleeve tray, and the sleeve trays are connected with the first output shaft in a matched mode; the other end of the sleeve is connected with the transition support on the inner side of the second support, one end of the magnetic bar is arranged in the sleeve, and the other end of the magnetic bar is connected with the transition support to form a whole and driven by the first output shaft to rotate; the main support is connected with the third support and the fourth support. The mall-batch permanent magnet iron removal device for the laboratory is low in price and high in iron removal efficiency, and can meet iron removal requirements of small-batch production and laboratories of lithium ion battery materials.

Description

technical field [0001] The invention relates to a laboratory-used small-batch permanent magnet iron removal device, which is applied to the intermittent circulation of small-batch powder materials to remove magnetic foreign objects from the powder materials. Background technique [0002] Driven by the new energy industry, the lithium-ion battery industry continues to maintain rapid growth; the development of lithium-ion batteries will surely ensure a higher service life and safety. Since the influence of magnetic foreign matter on the safety performance of lithium batteries is very critical, in order to obtain higher safety performance of lithium batteries, it is necessary to put forward higher requirements for the control of magnetic foreign matter in the production process of lithium ion battery materials. At present, the magnetic foreign matter of battery materials It is generally controlled within 50ppb, while NCA and other positive electrode materials used in Tesla requ...

Problems solved by technology

Existing solutions are as follows: first, realize the function of removing iron in small batches in the laboratory through the miniaturization of mass production equipment. The disadvantage is that the quotation is expensive. Iron or increase the frequency of iron removal to meet the iron removal requirements; the second is to process the laboratory iron removal materials through simple manual stirring with magnetic rods. The disadvantage is that it is time-consuming and laborious, the effect is not good, and it is easy to be contaminated during manual operation.
