Vacuum partition scraper type continuous defoaming machine

Abstract

The present invention discloses a vacuum partition scraper type continuous defoaming machine which comprises: a horizontally-arranged cylindrical separation tank, wherein the separation tank is provided with a feeding pipe, a vacuum pipe and a discharging opening; a main shaft which is arranged in the separation tank and is coaxial with the separation tank, wherein a motor at the end part of the separation tank drives the main shaft to rotate; a baffle which is arranged at the bottom of the separation tank and divides the lower part of the separation tank into a plurality of slurry chambers; material carrying discs which are fixed to the main shaft and do not make contact with the inner wall of the separation tank, wherein the number of the material carrying discs is consistent with that of the baffles, the material carrying discs are arranged on the sides of the feeding ends of the baffles, and discharging gaps are formed between the material carrying discs and the baffles; and a slurry scraper which is arranged above the baffles, wherein the slurry scraper is in contact with the disc surface part of the material carrying discs. By the adoption of the vacuum partition scraper type continuous defoaming machine, the defoaming time of materials with large surface tension is obviously prolonged in the defoaming process, and therefore the materials are fully defoamed.

Description

technical field [0001] The invention relates to a vacuum partition scraper type continuous defoaming machine, which belongs to the technical field of vacuum defoaming. Background technique [0002] In the current fields of fine chemical industry, raw material manufacturing, electronics industry, battery industry and new materials, the raw materials after stirring or pretreatment need to be separated from the internal bubbles before they can be finally filled or applied to subsequent production. The current degassing process is performed in static sealed tanks and motor-driven stirring paddles. The production capacity is extremely low, the probability of secondary pollution of raw materials is extremely high, and the waste of raw materials is extremely serious. [0003] Chinese patent CN 206424637 U discloses a "continuous vacuum defoaming and degassing device". This structure will cause blockage for extremely high viscosity slurry and lose its function, and the lack of outer...

The current degassing process is performed in static sealed tanks and motor-driven stirring paddles, which has extremely low production capacity, high probability of secondary pollution of raw materials, and extremely serious waste of raw materials

[0003] Chinese patent CN 206424637 U discloses a "continuous vacuum defoaming and degassing device". This structure will cause blockage for extremely high viscosity slurry and lose its function, and the temperature control of the raw material is missing due to the lack of an outer layer, and the efficiency is low.

[0004] Chinese patent CN 107774016 A discloses an "on-line vacuum degassing device". This structure cannot degas the slurry with extremely high viscosity, and lacks the outer layer to control the temperature of the raw material, resulting in low efficiency.

[0006] The appeal patent can conveniently realize online continuous degassing, but there is insufficient degassing time for the slurry with high surface tension. For the degassed slurry, the impact of the nozzle of the discharge pipe is easy to generate air bubbles again. Avoid, and eventually lead to certain limitations in the application of slurry industry
