Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vibrating screen, concretely relates to a kind of support device with damping effect for new vibrating screen screen mesh. BACKGROUND

[0002] Vibrating screen is usually used in material separation of mining, chemical industry, building material and other industries. With the emergence of large-scale mine, the production of table hour is increasing, and the material into vibrating screen is more and more, and the particle size required for screening is more and more. In order to screen the stone and sand that meet the building standard, the general building aggregate production line is first separated into stone and soil, then crushed, screened and sand made, sand washed, dewatered, sewage treated and so on. In the case of high clay content, the clay is very harmful to screening machine, crusher, vibrating screen and sand making machine. Especially when a large amount of clay is crushed, the wear parts of the crusher are easily damaged, the screen plate is easily blocked, and a large amount of clay is mixed into the sand, which brings work intensity to the sand washing machine, and the sand washing machine cannot be washed clean, which reduces the quality of machine-made sand. At the same time, the high clay content also increases the difficulty and investment cost of environmental dust collection. In the production of high-quality machine-made sand, water-washing vibrating screen is needed, and water needs to be sprayed on the screen mesh. For machine-made sand with a particle size of 3.75-5mm, the screen mesh has a small aperture, so the steel wire diameter of the screen mesh is also small. Generally, 4-5mm diameter spring steel wire is used to weave the screen mesh. Since the screen mesh is above the screen mesh support plate, it is indirectly in contact with the screen mesh support plate through the damping rubber pad, that is, the top of the screen mesh support plate is covered with a rubber pad, the screen mesh is placed on the rubber pad and supported by the screen mesh support plate, and the screen mesh support plate is welded to the vibrating screen box support frame. When the damping rubber pad is worn out or abnormally cut, the screen mesh will be in direct contact with the screen mesh support plate, which will cause the screen mesh to be abnormally cut, thus greatly reducing the service life of the screen mesh. SUMMARY

[0003] Therefore, the utility model designs a new vibrating screen screen mesh damping support device, which avoids the cutting effect of the screen mesh support plate on the damping rubber pad, prolongs the service life of the damping rubber pad, and greatly increases the service life of the screen mesh.
