Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a coating raw material screening and collecting mechanism and system. Background Art

[0002] Paints are usually used in the construction industry. After the raw materials of the paint are crushed and ground, they need to be screened and processed, and the raw materials with diameters that meet the requirements are mixed with solvents for processing.

[0003] The existing paint raw material filtering device is a single-layer filter, which cannot efficiently separate unqualified paint. Therefore, it is necessary to screen out different grades of paint raw materials multiple times. In addition, the screened paint raw materials may remain in the mesh of the filter and clog the filter. When the filter is clogged, the screening efficiency is reduced, which is not conducive to improving the production efficiency of the enterprise.

[0004] In addition, when a motor failure occurs in the existing coating screening device, it is very inconvenient to repair and disassemble.

[0005] Prior art, such as application number: 201810610047.8, discloses a coating screening device, including a tank body, which is provided with a feed port, a slag outlet and a discharge port; a slag collecting box fixedly connected to the outer wall of the tank body is provided at the slag outlet; a discharge pipe is fixedly connected to the discharge port, and a drive mechanism is slidably connected to a baffle plate on the discharge pipe; two screening plates are connected in the tank body, and the screening plates include a first screening plate located above and a second screening plate located below; a slag outlet groove and a plurality of discharge holes are fixedly provided on the screening plates, and a slag outlet mechanism is provided below the slag outlet groove; a first motor is fixedly connected in the tank body, and the output shaft of the first motor is coaxially connected to a distribution shaft; a distribution plate is provided above the screening plate, and the distribution plate is coaxially connected to the distribution shaft. The present invention sets two screening plates, first coarse screening and then fine screening. Compared with only one layer of filter screen directly finely screening the coating, two-stage screening can improve the screening efficiency. However, the two screening plates cannot be graded and collected after screening, and only play the role of efficient classification, and the collection efficiency is low. Utility Model Content
