Description

Technical Field

[0001] The invention relates to the technical field of chemical material screening machines, in particular to a self-cleaning chemical material screening machine. Background Art

[0002] The screening machine uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and is a vibrating screening mechanical equipment that divides materials such as sand, gravel, and crushed stone into different levels according to the particle size. The particle level of the screening depends on the screen surface. The screen surface is divided into three types: grate, plate screen, and mesh screen. The grate is suitable for screening large particles. The plate screen is made of punched steel plate with round, square or rectangular holes. It has a long service life and is not easy to clog. It is suitable for screening medium particles. The mesh screen is woven or welded by steel wire. The holes are square, rectangular or long strips. The long strip screen holes are suitable for screening wet materials. The advantage of the mesh screen is that the effective area is large. In the chemical industry, powder is the most common form of solid existence. The size and particle size distribution of powder particles have a great impact on the quality of the product. Products with different uses and different forms often have different requirements for powder particle size. Mechanical screening and grading is the most common and simplest method. It can intuitively judge the size of powder particles of different particle sizes according to the number of screen meshes that can pass through. It is also a control method for powder particle size and particle size distribution commonly used in production practice.

[0003] When the existing chemical material screening machine is in use, such as application number CN201921151433.1, a chemical material screening machine for chemical industry is provided, including a device body, a first conveyor belt and a second conveyor belt arranged horizontally are arranged inside the device body, a rotating motor is fixedly installed at the outer wall of the device body corresponding to the conveyor belt, three vertical discharge channels are arranged at the left end of the device body, and a discharge port is arranged below each discharge channel.

The utility model shortens the screening time of materials in the linear vibration screening device and improves the screening effect at the same time.
