Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a mineral processing and screening device with an anti-blocking structure. Background Art

[0002] Ore dressing and screening equipment is a device used to separate and extract useful minerals from raw ore, and is usually used in mining, metallurgy, building materials, chemical industry and other industries.

[0003] Announcement No. CN214107785U A screening device for mineral processing includes a device body, a feeding bin, and a discharging pipe. The feeding bin is arranged at the top of the device body, and the discharging pipe is embedded at the bottom of the device body. Through the setting of the feeding bin, the roller, the transmission rod, the first feeding trough and the feeding port, the ore can be rotated and transported, so that the dust can be prevented from floating out of the feeding bin during the screening of the ore. At the same time, the setting of the rotating seat, the first baffle, the rotating rod, the spring, the second feeding trough and the second baffle can be used to seal the discharging pipe, so that the dust can be prevented from floating out of the discharging pipe. Finally, the device is used to block the ore dust. Although this kind of mineral processing screening device has the effect of facilitating the blocking of ore dust, it is lacking in preventing the sieve plate from being blocked. Since this kind of screening device does not have a mechanism for cleaning the sieve plate, the holes of the sieve plate will be blocked by the ore during the screening, resulting in a poor screening effect.
