Water-based paint defoaming equipment

Abstract

The invention provides water-based paint defoaming equipment, including a control device, a liquid storage tank, a sealing cover, a motor, and a discharge tank. It is characterized in that: the control device is connected to the motor through a power supply, and the sealing cover is installed on the liquid storage tank At the top, the motor is installed above the outside of the sealing cover; at the top of the liquid storage tank, a variable speed stirring device, a feed inlet and an exhaust hole are installed, and the variable speed stirring device is composed of a stirring shaft, a stirring blade and a gear stirring blade ; A multi-stage filter defoaming layer is installed at the bottom of the liquid storage tank, and the multi-stage filter defoaming layer is composed of a first-stage variable-diameter defoaming layer, a secondary variable-diameter defoaming layer and a vibrating crushing layer, wherein the The vibrating crushing layer includes multiple transverse shafts and metal needles connected on the surface of the transverse shafts; the discharge tank is arranged under the liquid storage tank and connected by a liquid discharge pipe. The beneficial effects of the invention are: the water-based paint can be fully stirred, and the bubbles can be broken through multi-stage filtration and vibration to achieve the purpose of elimination.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of chemical production equipment, in particular to water-based paint defoaming equipment. [0003] 【Background technique】 [0004] During the production of water-based paint, a large number of air bubbles will be generated. Therefore, defoaming is required. However, most companies use defoamers, which are fast, time-saving, and cost-effective. However, the defoamer will lose its activity during use, thus losing the ability to control or defoam. This requires the method of adding a small amount of times when using the defoamer, which will inevitably increase the chance of bacterial contamination. Therefore, some companies are now turning to mechanical defoaming, through vibration or pressure changes, to promote the bursting of the foam to achieve the purpose of defoaming. Because mechanical defoaming can reduce the chance of bacterial contamination and reduce the complexity of the culture medium, it can also...
