Description

Technical Field

[0001] The utility model relates to a filter screen device, in particular to a continuous filter screen device for chemical additives, belonging to the technical field of screening. Background Art

[0002] Chemical additives are chemical additives used in a certain industry. There are many types of chemical additives, generally including metal processing additives, plastic additives, papermaking additives, construction additives, water treatment additives, coating additives, leather additives, additives for the electronics industry, textile printing and dyeing additives, wood additives, etc. However, chemical additives will clump during transportation and storage. For example, thickening lubricants used in oil field drilling will clump after being exposed to moisture, resulting in the thickening lubricant being difficult to mix fully with the material when added to the material, resulting in floating oil or coagulation of the thickening lubricant.

[0003] The current publication number is CN217910706U, a continuous filtering and screening device for chemical additives for oil fields, including a first bracket, a protective barrel is fixedly connected to the upper surface of the first bracket, the inner wall of the protective barrel is provided with rollers, and the rollers are evenly distributed on the inner wall of the protective barrel, a screening barrel is provided inside the protective barrel, the outer wall of the screening barrel is provided with screening holes, and the screening holes are evenly distributed on the outer wall of the screening barrel, and the inner wall of the screening barrel is provided with spiral blades.

[0004] In the above scheme, although there are many benefits, there are also the following disadvantages: the stirring rod is driven by the second motor to rotate in the crushing barrel, and the rotating stirring rod can crush the thickened lubricant that has accumulated in the crushing barrel, and then the valve is opened to transfer the thickened lubricant in the crushing barrel to the screening barrel through the equipment pipe. However, since the valve is closed when the thickened lubricant is crushed, the thickened lubricant after crushing will accumulate at the bottom end of the crushing barrel, and there may still be some lumps in the thickened lubricant after crushing. When the valve is opened, it may cause blockage in the equipment pipe, affecting the entry of the thickened lubricant after crushing into the screening barrel, reducing the practicability of the device. Summary of the invention

[0005] Technical issues solved
