Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screens, in particular to a dust and mist reduction device for vibrating screens. Background Art
[0002] Vibrating screen is a commonly used mechanical equipment, mainly used for screening work. The vibrating screen can use the vibration of its own porous working surface to screen a mixture of particles of different sizes, so that the particles can be graded according to size. It plays an important role in my country's industrial and mining enterprises and is an indispensable screening tool. Due to the material properties of the mining vibrating screen and the working mode of the vibrating screen, water dust suppression cannot be used for dust prevention and control. Therefore, a large amount of dust will be generated during the operation of the vibrating screen, which can easily cause environmental pollution and have adverse effects on the equipment and the health of employees. In addition, the existing vibrating screen is easily blocked by materials, which reduces the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
