Continuous production defoaming equipment

Abstract

The invention discloses continuous production defoaming equipment which comprises a base, a supporting frame is fixedly installed at the upper end of the base, a tank body is detachably installed at the upper end of the supporting frame, a discharging pipe is connected to the lower end of the tank body in a penetrating mode, and a defoaming mechanism is connected to the middle of the upper end of the tank body in a penetrating mode. The lower portion of the defoaming mechanism penetrates through the tank body and extends into the tank body, the defoaming mechanism and the tank body are movably installed through a bearing, a fixing plate is fixedly installed on the rear portion of the upper end of the tank body, a driving mechanism is fixedly installed at the front end of the fixing plate, and the driving mechanism is in transmission connection with the defoaming mechanism. A feeding pipe is inserted into the left side of the upper end of the tank body, a vacuum pipe is inserted into the right side of the upper end of the tank body, and a vacuum pump is fixedly mounted at the other end of the vacuum pipe. According to the continuous production defoaming equipment, defoaming is efficient and thorough, caking or large-particle materials in slurry can be smashed at the same time, and the continuous production defoaming equipment is compact in structure, stable in transmission, diverse in function and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of lithium ion production, in particular to a continuous production defoaming device. Background technique [0002] With the development of new energy vehicles, the requirements for lithium-ion power batteries are getting higher and higher, and the requirements for the production process of lithium batteries are also getting higher and higher. In the process of slurry mixing, agglomeration will occur. Although the slurry has been dispersed, crushed and filtered, there will be very small agglomerates or agglomerations of the slurry. The agglomerated slurry will reduce the life of the filter element during the filtration process and cause the slurry to be in the process of filtration. When the coating head squeezes and coats, there is a risk of scratching the substrate or coating surface, which will affect the quality of the pole piece; before the coating process of the lithium-ion battery production, the slur...

Problems solved by technology

In the process of slurry mixing, agglomeration will occur. Although the slurry has been dispersed, crushed and filtered, there will be very small agglomerates or agglomerations of the slurry. The agglomerated slurry will reduce the life of the filter element during the filtration process and cause the slurry to be in the process of filtration. When the coating head squeezes and coats, there is a risk of scratching the substrate or coating surface, which will affect the quality of the pole piece; before the coating process of the lithium-ion battery production, the slurry will be vacuumed and degassed again after the dispersion and stirring are completed. The purpose is to eliminate the air bubbles in the slurry and ensure the influence of air bubbles on the surface cracking of the pole piece coating during the drying process of the coating layer

[0003] At present, the commonly used defoaming equipment is mainly composed of a stirring motor, a vacuum port, a stirring defoaming paddle and a defoaming tank. The stirring defoaming paddle stirs in the defoaming tank to discharge the air bubbles in the slurry. This design function Single, low defoaming efficiency, long time, and there will be agglomerates and large particle materials in some slurries, which cannot be crushed. The accumulation of these agglomerates or large particle materials will affect the normal use of lithium batteries. Therefore, we Proposed a continuous production defoaming equipment
