Sealed mixing equipment capable of carrying out secondary feeding

Abstract

The invention provides sealed mixing equipment capable of performing secondary charging, which comprises a mixing barrel and a barrel cover, and a stirring shaft is arranged in the mixing barrel; a first feeding pipe is arranged on the side wall of the mixing barrel in a communicating manner, and a first electromagnetic valve is arranged on the first feeding pipe; a second feeding pipe is arranged on the barrel cover, a second electromagnetic valve is arranged on the second feeding pipe, a transfer box is arranged at the top end of the second feeding pipe, a third feeding pipe is arranged on the side wall of the transfer box, and a third electromagnetic valve is arranged on the third feeding pipe; a buffer pipe is arranged on the outer side of the top of the mixing barrel, the bottom end of the buffer pipe is communicated with the interior of the mixing barrel, a limiting frame is arranged on the inner wall of the bottom end of the buffer pipe, an end cover is arranged at the top end of the buffer pipe, a piston block is arranged in the buffer pipe, and the piston block slides along the inner wall of the buffer pipe in a sealed mode to achieve adjustment of air pressure; the device is novel in structure, materials can be conveniently added in the mixing process, the change of air pressure can be reduced as much as possible, the air pressure can be subsequently adjusted in an auxiliary mode, and the proper internal air pressure condition is maintained.

Description

technical field [0001] The invention relates to the field of mixing equipment, and more specifically, relates to a sealed mixing equipment capable of secondary feeding. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, are characterized by their safety, specific capacity , self-discharge rate and performance-price ratio are superior to lithium-ion batteries. During the production and processing of lithium batteries, it is necessary to mix th...

AI Technical Summary

Problems solved by technology

During the production and processing of lithium batteries, it is necessary to mix the inner core materials. In addition to the main materials, various materials will be added. For some mixed reactions that require air pressure, the feeding part needs to be opened midway to add materials, resulting in internal air pressure. Most of the traditional mixing equipment does not consider the impact of changes, or only releases pressure by simple exhaust, or pressurizes by supplying air to the inside, the air pressure adjustment range is large, and the control adjustment is not accurate
