Dust removal building structure of sand making tower

The dust removal building structure of the sand making tower building comprises a support, the inner wall of the support is connected with a receiving barrel, the outer wall of the receiving barrel is connected with a plurality of draught fans, and a plurality of through holes are formed in the outer wall of the receiving barrel; materials are put into the feeding pipe, the descending speed of the materials is reduced through the two symmetrical inclined plates, meanwhile, the draught fan is started, the draught fan blows the materials to enable the materials to be blown to the filter plate, dust in the materials penetrates through the filter plate and falls into the separation barrel, the effect of separating the dust from the materials is achieved, the materials continue to fall downwards through the gravity of the materials, and the materials are prevented from falling off. By means of the structure, materials are prevented from being accumulated on the filter plate and falling onto the rotating plate, the
