A defoaming machine

Abstract

A defoaming machine is disclosed and comprises a first defoaming mechanism and a second defoaming mechanism. The first defoaming mechanism comprises a defoaming tank and a first motor disposed at the top of the defoaming tank. The output shaft of the first motor is connected to a transmission shaft. A butterfly defoaming disk is mounted at the transmission shaft. An outer tank sleeves the defoaming tank, and an inner cavity for containing temperature controlling water is formed. The second defoaming mechanism comprises a cylinder, a second motor and a rotary drum. The bottom cylinder wall of the cylinder is provided with a feeding pipe. The top cylinder wall of the cylinder is provided with a discharging pipe. A main shaft is rotationally and hermetically mounted to the cylinder wall of the cylinder. The tail end of the main shaft is mounted with the second motor. The main shaft in the cylinder is fixedly connected to the rotary drum. The feeding pipe penetrates into the rotary drum. The discharging end of the feeding pipe is disposed at a position on the inner wall of the rotary drum, with the position being corresponding to the axis of the main shaft. The discharging pipe penetrates into the rotary drum, and the feeding end of the discharging pipe is disposed at the top of the inside of the rotary drum. A discharging port is connected to the feeding pipe through a slurry conveying pipe. The defoaming machine achieves double-cylinder twice defoaming, controls slurry temperature and improves defoaming effects.

Description

technical field [0001] The present invention relates to the technical field of defoaming devices, more specifically to a defoaming machine. Background technique [0002] Vacuum defoaming technology is widely used in the defoaming of food, chemical and other liquid slurries with bubbles. The existing slurry degassing generally adopts the chemical method of adding defoaming agent or the physical method of vacuum stirring and defoaming. The chemical method requires an additional defoamer, and some defoamers may have adverse reactions to raw materials. The vacuum stirring defoaming method needs to place certain materials in a closed container, and use a vacuum pump to evacuate while stirring. This method is a physical method, which usually does not change the physical and chemical properties of the material. However, traditional equipment cannot meet the degassing requirements of high-viscosity slurry. The viscosity of the slurry is high, and it is necessary to increase the va...

Problems solved by technology

This method is a physical method, which usually does not change the physical and chemical properties of the material, but the traditional equipment cannot meet the degassing of high-viscosity slurry. The viscosity of the slurry is high, and it is necessary to increase the vacuum degree and prolong the stirring time. With the increase of the vacuum degree, the boiling point of the water in the slurry will decrease, and the water will volatilize faster at room temperature, and more volatile components in the slurry will be lost. , resulting in agglomeration of the slurry, and even changes in the composition of the slurry, affecting the quality of the slurry
