Problems solved by technology

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

Embodiment 1

[0046] like figure 1 As shown, a vacuum partition flat plate continuous degassing machine of the present embodiment comprises a horizontally arranged cylindrical separation tank 1, and the separation tank 1 is provided with a feed pipe 11, a vacuum pipe 12 and a discharge port 13; Set the main shaft 21 coaxial with the separation tank 1, the main shaft 21 and the two ends of the separation tank 1 are connected by bearings, the end of the separation tank 1 is provided with a motor 2 to drive the main shaft 21 to rotate; the main shaft 21 is provided with six equally spaced belt discs 3. The disc 3 with material is rotated and sealed with the inner wall of the separation tank 1 to divide the interior of the separation tank 1 into seven chambers, and the disc 3 with material is provided with a discharge hole 31 to communicate with two adjacent chambers.

[0047] In this embodiment, the separation tank 1 is first evacuated through the vacuum tube 12, the slurry 8 enters the separ...

Embodiment 2

[0050] like figure 2As shown, in this embodiment, as a further optimization of Embodiment 1, a hollow defoaming column 4 with a mesh 41 is arranged between two adjacent discs 3 with material, the defoaming column 4 is coaxial with the main shaft 21, and the defoaming column 4 With the rotation of the disc 3 with the material, the defoaming column 4 can simultaneously perform thin film defoaming on the slurry 8 in the chamber, thereby increasing the thin film area, increasing the defoaming efficiency and defoaming effect.

Embodiment 3

[0052] like Figure 4 As shown, this embodiment is further optimized as Embodiment 1. The outer surface of the separation tank 1 is provided with a cooling and heating medium circulation chamber 5, and the cooling and heating medium circulation chamber 5 is provided with a cooling and heating medium inlet 52 or a cooling and heating medium outlet 51. A cold and hot medium outlet 51 or a cold and hot medium inlet 52 is arranged below the medium circulation chamber 5, and the temperature in the separation tank 1 can be adjusted by passing in a refrigerant or a heat medium, so that the separation tank 1 is always in the process temperature range for the degassing of the slurry 8, and more It is beneficial to the defoaming of the slurry 8.

Abstract

The invention discloses a vacuum partition flat plate type continuous defoaming machine which comprises a horizontally-arranged cylindrical separation tank, and the separation tank is provided with a feeding pipe, a vacuum pipe and a discharging opening. A main shaft coaxial with the separation tank is arranged in the separation tank; a motor is arranged at the end part of the separation tank to drive the main shaft to rotate; and a plurality of material carrying discs are arranged on the main shaft, the material carrying discs and the inner wall of the separation tank are rotationally sealed to divide the interior of the separation tank into a plurality of cavities, and discharging holes are formed in the material carrying discs to communicate every two adjacent cavities. The vacuum partition flat plate type continuous defoaming machine is simple in structure, high in defoaming treatment efficiency and good in continuous defoaming effect.

Description

technical field [0001] The invention relates to a vacuum partition flat plate 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 l...
