Description

Vibrating screen with anti-blocking holes and adjustable screen mesh Technical Field The utility model relates to a vibrating screen with an adjustable anti-blocking hole, in particular to a vibrating screen with an adjustable anti-blocking hole, which is applied to the technical field of vibrating screens. Background The vibrating screen is used as key equipment in the material screening field, and is widely applied to industries such as mines, building materials, chemical industry, grain processing and the like, and the core working principle is that a screen body and a screen installed inside are periodically vibrated by means of a vibration source (such as motor driven eccentric structure to vibrate), so that materials can be thrown, slid and the like on the surface of the screen, and in the material movement process, particles smaller than the aperture of the screen are separated through the screen holes, and particles larger than the aperture are discharged along the movement track of the screen, so that the operations such as classification, impurity removal, screening and the like of the materials are completed. Although the vibrating screen is widely applied in industrial production, certain problems still exist in facing complex material working conditions (such as moisture, high viscosity and fibrous materials), when the wet materials are treated, the materials are easy to be adsorbed on the surface of a screen mesh due to moisture to form viscous agglomeration, the fibrous materials are easy to wind and block at the positions of the screen holes, the high-viscosity materials can fill the screen holes to prevent the materials from penetrating through the screen normally, the screening efficiency is directly reduced, the equipment needs to be frequently shut down and cleaned, the production flow is interrupted, the labor and time cost is greatly increased, and the utility model is provided in view of the problems.
