[0003] The prior art CN214812557U discloses a clean coal de-mediation screen, which includes a body, a sieve plate, a rotating plate, a sliding block and a scraper. A support plate is welded on the shell, and a column is arranged on the support plate. The sieve plate is slidably arranged on the column through a sieve plate mounting frame. The screw rod is driven to reciprocate through a transmission device, and the scraper reciprocates synchronously to clean the sieve plate, thereby preventing the sieve holes from being blocked.

[0004] In the above-mentioned clean coal de-mediation screen, since the scraper and the sieve plate are in contact with each other and the height of the scraper is not easy to adjust, when the sieve plate is removed, it is necessary to remove the bolts and squeeze the mounting frame to compress the spring and then pull out the sieve plate after a height difference is generated between the sieve plate and the scraper.
