Description

Adjustable multilayer precision vibration screening device
Technical Field
The invention belongs to the field of screening machinery, and relates to an adjustable multilayer precise vibration screening device.
Background
At present, screening machines are widely used in multiple industries such as coal, metallurgy, mines, chemical industry, food and the like, and the existing screening operation equipment utilizes the relative motion of bulk materials and a screen surface to enable partial particles to penetrate through screen holes, so that materials such as sand, gravel, broken stone and the like are divided into vibrating screening mechanical equipment with different grades according to the particle size. The particle grade of the screening is determined by the screen surface, which is divided into three types of grate, plate screen and mesh screen. The grate is suitable for screening large-particle materials, and gaps of the grate are 1.1-1.2 times of the particle size of undersize materials and are generally not suitable to be smaller than 50 mm. The plate screen is formed by punching a steel plate, holes are circular, square or rectangular, the aperture is generally 10-80 mm, the service life is long, the plate screen is not easy to block, and the plate screen is suitable for screening medium particles. The mesh screen is woven or welded by the steel wire, and the hole is square, rectangle or rectangular shape, and the aperture is generally 6 ~ 85 millimeters commonly used, and rectangular shape sieve mesh is suitable for screening moist material, and the advantage of mesh screen is that effective area is great. The screening machine is divided into rolling screening and vibrating screening. The rolling screening includes sieve shaft type screening machines, drum screens, solid and spiral roller screens, blade type roller screens and the like, and the vibration screening basically comprises banana screens, high clothes screens, relaxation screens and the like.
The principle of screening general particle materials is as follows: the particles pass through the sieve plate and meet the sieve holes, the materials with the particle size smaller than the sieve holes pass through the sieve holes to become undersize materials, and the particles with the particle size larger than the sieve holes do not pass through the sieve holes to become oversize materials. The vibrating screen has the advantages that the vibrating screen strongly vibrates due to the screen box, so that the phenomenon that the screen holes are blocked by materials is reduced, and the screen has higher screening efficiency and productivity.
Most of the mainstream screening devices in the current market mainly adopt a vibrating screen and a fixed screen as an auxiliary screen; however, as for the existing vibrating screens, the vibrating efficiency still has a larger lifting space, so that there is a need to invent an adjustable multi-layer precise vibrating screening device which has the advantages of stability, reliability, low consumption, low noise, long service life, stable vibration mode, high screening efficiency and the like.
