Abstract

The invention provides a paint filtering system with a self-flushing function. The paint filtering system comprises a paint screen for filtering paint, a pump, a storage tank for storing paint and a control module, and the paint screen is provided with a slurry inlet, a slurry outlet, flushing holes and a screened residue outlet; an outlet of the pump is communicated with the slurry inlet through a slurry inlet pipe; a qualified slurry water outlet pipe educing the filtered paint is communicated to the slurry outlet and provided with a third valve; a first flushing pipe is communicated to one flushing hole and provided with a second valve; a residue discharge pipe is communicated to the screened residue outlet and provided with a first valve; a measuring pipe is connected between the slurry inlet and the slurry outlet and provided with a pressure difference detection device. Real-time monitoring is conducted on a pressure difference of the slurry inlet and the slurry outlet, the filtering effect of the screen cylinder is monitored, automatic flushing is achieved if necessary, the whole process is automatically controlled, the flushing efficiency is high, the effect is good, different pressure difference thresholds can be set, and flexible control can be achieved according to different filtering effects.

Description

technical field [0001] The invention relates to a paint filtering system, in particular to a self-flushing paint filtering system. Background technique [0002] In the papermaking process, coatings are used for surface treatment of paper, which can improve the surface properties of paper pages. Coating on paper can improve the printability and appearance. Before the coating operation, the coating itself should be filtered to filter out the large particle size substances in the coating to ensure the quality of the paper after coating. [0003] Most of the paint filtration in the prior art is a vibrating filter sieve. Although the filtering effect can also be achieved, the structure is complex, the filtering effect is difficult to control, and the filtering efficiency is low. It is difficult to realize automatic control. Contents of the invention [0004] The technical problem to be solved by the present invention is: in order to solve the low efficiency, incapable of cont...
