Coating grinding and closed stirring double-circulation all-in-one machine

Abstract

The invention relates to the technical field of coating grinding, and discloses a coating grinding closed stirring double-circulation all-in-one machine which comprises two vacuum pumps, a stirrer A, a valve, a ventilation pipeline, a sand mill and a stirrer B. The two vacuum pumps can convey raw materials, one vacuum pump can convey the raw materials to the stirrer A, and the other vacuum pump can convey the raw materials to the stirrer B; the other vacuum pump can convey raw materials to the stirrer B. The number of the valves is four, and the four valves are the valve 1, the valve 2, the valve 3 and the valve 4. Through the arrangement of the totally-closed stirrer A and the totally-closed stirrer B, zero emission of VOC is achieved, meanwhile, pollution to the environment atmosphere is reduced, manual cleaning is omitted, the economic cost is greatly reduced, time and labor are saved, the product quality and the production efficiency are improved, the problem of high emission of VOC in the coating industry is thoroughly solved, and the production cost is reduced. VOC in the coating industry is effectively controlled, and emission to the atmospheric environment is reduced.

Description

technical field [0001] The present invention relates to the technical field of paint grinding, and more particularly, to a paint grinding and stirring double-cycle integrated machine. Background technique [0002] like figure 2 As shown, the prior art of coating grinding and dispersing is to grind the material in the material tank "A" by a grinder and then transfer it to the material tank "B", and then the two tanks are exchanged for grinding again. Each batch of products needs to be ground for 3 to 5 times, or 3 to 5 grinding machines are connected in series to achieve the grinding effect. This production method requires more workers or large investment, which cannot achieve the purpose of energy saving and environmental protection. [0003] The traditional material tank "A" and material tank "B" are ordinary iron semi-open tanks. There are wheels under the tank for easy movement, and most of the tanks are open or a movable cover is installed on the top. When the grinder ...

AI Technical Summary

Problems solved by technology

[0002] like figure 2 As shown, in the prior art of paint grinding and dispersion, the material in the material tank "A" is ground by a grinder and then transported to the material tank "B", and then the two tanks are exchanged for grinding again. Each batch of products needs to be ground for 3 to 5 times, or connect 3 to 5 grinding machines in series to achieve the grinding effect. This kind of production method requires many workers or large investment, and it cannot achieve the purpose of energy saving and environmental protection.

[0003] The traditional material tank "A" and material tank "B" are both ordinary iron semi-open tanks, with wheels under the tank for easy movement, and most of the tanks are open or equipped with movable covers on them. When the grinder grinds the material in material tank "A" and transports it to material tank "B", volatile gas (VOC) will be emitted into the atmosphere. When the material in "A" tank is evacuated, it is necessary to use Solvent oil cleans the inside of the tank. During the cleaning process, the solvent will also volatilize a large amount of harmful gases (VOC) and emit them into the atmosphere, resulting in high emissions to the atmosphere, affecting the quality indicators of the atmosphere, and high production costs during production. , Low production efficiency
