Lithium battery lithium salt automatic pneumatic conveying system

Abstract

The lithium battery lithium salt automatic pneumatic conveying system disclosed by the present invention includes an air flow source, a warehouse pump, a conveying pipeline, a warehouse pump air intake control unit, a pulsed air intake control unit, a first material bin, a PLC controller, and a conveying pipeline The feed port of the warehouse pump is docked with the discharge port of the warehouse pump; the warehouse pump air intake control unit includes a first air inlet and a first air outlet, the first air inlet is connected to the air source, and the first air outlet is connected to the warehouse pump; The pulsed air intake control unit includes a second air inlet and a second air outlet, the second air inlet is connected to the air source, and the second air outlet is connected to the conveying pipeline near its feed port; the first feed bin The feed point is connected to the discharge port of the conveying pipeline, which realizes automatic high-efficiency conveying, and the whole system is conveyed with low flow rate, high concentration and high sealing performance, which ensures that the electrolyte lithium salt is fully isolated from air and harmful metals. And the crushing rate of the material is strictly controlled.

Description

technical field [0001] The invention relates to the technical field of automatic transportation of electrolyte lithium salt powder in the lithium battery industry, in particular to a lithium battery lithium salt automatic pneumatic transportation system. Background technique [0002] As an important part of lithium-ion batteries, the electrolyte has extremely high quality requirements for raw materials (ie electrolyte lithium salts), and impurities are required to be in parts per million (ie ppm level), so the production process must ensure that raw materials do not Contaminated by other metals, not in contact with air or other impurities, and the crushing rate of lithium salts during transportation needs to be strictly controlled. The traditional method is to use manual handling or mechanical conveying, which not only has high work intensity and low conveying efficiency, but also affects the quality of raw materials that are easily contaminated by air, other metals or impur...
