Convenient-to-discharge mixing tank for lithium ion battery cathode powder material

Abstract

The invention discloses a convenient-to-discharge mixing tank for a lithium ion battery cathode powder material. The convenient-to-discharge mixing tank comprises a base, wherein a discharge chamber is arranged at the top of the base; a striker plate is arranged at the top of the discharge chamber; a mixing chamber is arranged at the top of the striker plate; and a stirring device is arranged in the mixing chamber; and the stirring device consists of a stirring shaft, stirring cross bars, stirring vertical bars and a stirring blade. The convenient-to-discharge mixing tank is simple in structure, reasonable in design and convenient to use; owing to the discharge chamber, the material falling speed can be greatly reduced, and generation of dust is reduced; the material is discharged out from a discharge pipe through a spiral discharging device; secondary stirring and mixing of the battery cathode material can be conducted, so that the material can be mixed more radically; owing to inclined arrangement of the discharge pipe, dust is avoided, and sufficient resource utilization is realized; and a clean and comfortable working environment is provided for staff, and the production efficiency cannot be influenced too much.

Description

technical field [0001] The invention relates to a battery material production equipment, in particular to a mixing kettle for lithium-ion battery cathode powder materials which is convenient for discharging. Background technique [0002] In the production process of lithium batteries, it is necessary to mix lithium-ion battery cathode powder materials such as lithium cobaltate, lithium manganese oxide, ternary materials or lithium iron phosphate in a mixing tank. During the process, due to the fast flow of powder materials, a large amount of dust will be generated, which will not only pollute the environment, endanger the health of workers, but also cause a waste of resources. Contents of the invention [0003] The object of the present invention is to provide a mixing kettle for lithium-ion battery positive electrode powder materials that is convenient for discharging, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve th...
