Technical Field

[0001] The utility model relates to the technical field of production and processing of curing agent raw materials, in particular to screening equipment for production of mining curing agents. Background Art

[0002] Screening equipment used in the production of mining solidifiers can separate fine powder additives from coarser mineral raw materials, but during the separation process, the screen may become clogged.

[0003] Therefore, the staff needs to clean the screen after each screening to avoid blockage. However, in order to prevent dust from flying during the screening process, the existing curing agent screening equipment will install a dust cover on the upper end of the screening equipment. These dust covers are often welded to the screening equipment. In this way, the screen is located inside it, which is very inconvenient to clean and has many blind spots for cleaning.

When in use, the vibration motor 31 on the outer surface of the screening chamber 3 is started to drive the screening mechanism 2 to vibrate through the rubber spring 11, thereby starting the screening work, and the powdery fine material will fall into the screening chamber 3 and be collected, and the coarse material will remain inside the screening mechanism 2.

[0024] Furthermore, a discharge port 32 is provided at the lower end of the screening chamber 3, and a feed port 41 is provided at the upper end of the dust cover 4. During use, after the screening work is completed, the end cover of the discharge port 32 is opened, and the fine material will be discharged from the discharge port 32. By setting the feed port 41, after the dust cover 4 is closed, material can continue to be added to the inside of the screening mechanism 2.

[0025] Furthermore, long clamping blocks 42 are fixedly connected to the left and right sides of the lower surface of the dust cover 4, and a second magnetic surface 421 is provided on the lower end surface of the long clamping block 42.
