Description

Technical Field

[0001] The utility model relates to the technical field of coating raw material sieving residue, in particular to a closed and pullable sieving residue measuring tool. Background Art

[0002] The screen commonly used in production at present is a cylindrical open screen, which is one-piece and inseparable. This open screen is usually used to screen powder, emulsion, latex paint, etc. in production. In the production process, it is necessary to weigh the screened material, weigh a certain amount of material and put it into the screen, connect the faucet with a rubber tube, pinch the rubber tube and turn on the faucet, use the pressurized flat water flow generated at that time to rinse the powder, move back and forth and repeatedly rinse the material until there is no remaining material, observe, touch and weigh the weight of impurities in the screen, so as to achieve the effect of screening. This screening method will generate a lot of dust during the flushing process, which will cause harm to the human body when inhaled, and the harm is particularly serious in the process of flushing titanium dioxide. In addition, during the flushing process, the raw materials splash and the dust diffuses, resulting in a smaller actual total amount of screen residue, which affects the final data. The one-piece screen needs to replace the screen of different calibers each time it is used according to the use requirements, and it is not easy to control the water pressure when the rubber hose is held to control the water flow, which will eventually lead to low work efficiency.
