Filtering device for building coating

Abstract

The invention relates to the technical field of coating processing equipment, in particular to a filtering device for a building coating. The filtering device comprises a filtering frame, at least one group of crushing mechanisms, a driving motor, guide tubes and an air pump, wherein a plurality of filtering holes are uniformly formed in the bottom surface inside the filtering frame; the crushing mechanism comprise a gear roller I and a gear roller II engaged with the gear roller I; the gear roller I is in meshed linkage with a gear II on the gear roller II in a sleeving manner through a gear I on the gear roller I in the sleeving manner; the rotating shaft of the driving motor is connected with one end far away from the gear I, of the gear roller I; the upper ends of the guide tubes are connected with the bottoms of the filtering holes; the guide tubes are internally provided with moveable sealing plates; the output end of the air pump is connected with one end of a hose; the other end of the hose is connected with the bottoms of the guide tubes; the air pump is electrically connected with a timing switch through a lead. The filtering device has the advantages of being simple and convenient to operate, good in filtering effect, short in filtration time, high in working efficiency and the like, and the characteristics of being free of manual operation, low in working intensity and the like in the whole process.

Description

technical field [0001] The invention relates to the technical field of paint processing equipment, in particular to a filter device for architectural paint. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. Coatings can be coated on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. Existing building walls are usually coated with paint, the main purpose is to prevent wall corrosion, water seepage and heat preservation, so the paint used on building walls must have good thermal insulation performance, and the paint ingredients usually need to be filtered after production, so as to To rem...

AI Technical Summary

Problems solved by technology

This scheme can realize the automatic cleaning and fast filtering functions of the coating equipment, etc., but there will be the following problems after long-term use: 1. Since the filter frame is driven to move up and down, left and right by means of a cam, and the distance between the cam and the follower is When point or line contact, it is easy to wear, and it is only suitable for occasions where the transmission force is not large. Obviously, this scheme will wear the cam after working for a long time, resulting in frequent replacement of the cam; 2. The wear of the cam or other parts, such as the limit The failure of the spring return or the movement of the limit moving piece in the limit hollow column will lead to the failure of the cleaning column head to be smoothly inserted into the conical filter hole and damage the equipment; limitations
