When the sand reaches the filter screen 403 engaged in the slot 402, the impurities will be intercepted by the filter screen 403. The sand passes through the filter screen 403 and enters the interior of the housing 401. Under the influence of gravity, the impurities will be discharged from the first discharge port 406, and the sand will be discharged from the second discharge port 407 to prevent the sand and impurities from mixing again.
