Technical Field

[0001] The utility model relates to the technical field of sand powder processing, in particular to a screening device for sand powder grinding. Background Technique

[0002] The use of a screening device for sand powder grinding is that when the sand powder is ground, there may be large differences in the particle sizes. The primary function of the screening device is to screen and classify these raw material particles to ensure that the particle sizes meet the requirements of subsequent processes. For materials with smaller particle sizes, the screening device can also perform pre-screening before grinding to reduce the mud powder content and improve the grinding efficiency.

[0003] As described in a screening device for sand powder grinding (the authorization announcement is CN 215030918U) disclosed on the patent network, "A screening device for sand powder grinding includes a support frame. The top of the support frame is fixedly connected with a screening box. The top of the screening box is hinged with a top plate through a hinge. The inside of the screening box is slidably connected with a tray."

[0004] Regarding the above description, the applicant believes there are the following problems:

[0005] During the use of this utility model, the device directly pours the sand powder into the inside of the screening box from the top, drives the turntable to rotate through a motor, so that the traction rod drives the traction block to move up and down, and then the traction block drives the sieve plate to move up and down, so as to be able to jitter and screen the sifted powder falling on the sieve plate. However, during actual use, when the sand powder is continuously input into the screening device, a large amount of materials may accumulate on the screening layer, resulting in some materials not being fully in contact with the screening layer, thus reducing the screening effect, and there are still impurities that have not been screened out in the screened materials, affecting the product quality.
