Filtration system for coating production

Abstract

The invention provides a filtration system for coating production. The filtration system comprises a liquid storage tank, a pressure pump, a filtration device and a return pipeline. The liquid storage tank is used for storing a coating stock solution to be filtered. The pressure pump is communicated with the liquid storage tank. The filtration device is communicated with the pressure pump, and the pressure pump pumps the coating stock solution in the liquid storage tank into the filtration device for filtration. The return pipeline makes the filtration device and the liquid storage tank communicated. The flow direction of the coating stock solution in the filtration device is parallel with the surface of a filtration screen of the filtration device. According to the filtration system, no flow channel dead corner exists, the effective filtration area of the filtration screen is not reduced, the filtration screen is not blocked, and thus the service life of the filtration screen is prolonged.

Description

technical field [0001] The invention relates to the field of paint production, in particular to a filter system for paint production. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. [0003] Filtration is an important step in the paint production process. Impurities and particles are removed by filtration. The main tool used in the filtration process is a filter sieve, which is a simple sieve with a filter mesh at the bottom. When this type of equipment is used, the paint to be filtered is injected into the sieve, and the paint is filtered out from the filter screen by manual stirring. Although this kind of equipment can complete the filtration, the manual stirring is inefficient and labor-intensive. The utili...

Problems solved by technology

Although the agitator driven by the motor in the paint filter can realize the agitation of the paint, promote the filtration of the paint, and reduce the manual mixing procedure in the whole process, but because the agitator and the motor are installed on a fixed frame, it is very difficult to disassemble and clean the filter screen. Inconvenient; the paint filter has a container under the filter sieve. After filtering, the container needs to be unloaded and then poured into the paint bucket. The problem of clogging the filter screen
