Abstract

This utility model discloses a horizontal centrifuge with a slagging function, belonging to the field of centrifuges. It includes an inner centrifuge housing with filter slag holes on its outer arc surface. Stepped surfaces are provided on both the front and rear sides of the inner centrifuge housing. A filter slag discharge pipe is fixedly installed on the upper surface of one of the stepped surfaces by bolts. A bearing cavity is provided on the lower surface of the filter slag discharge pipe. A sealing gasket is movably fitted onto the outer arc surface of the bearing cavity of the filter slag discharge pipe. Abutment grooves are provided on both the upper and lower surfaces of the sealing gasket. Through the combined action of grinding and slagging, residue accumulation in key parts of the centrifuge can be prevented. In industrial production, some reaction residues may be sticky. If centrifugal force alone is insufficient to completely remove them from the equipment, grinding reduces and refines the stickiness of the residues, while slagging promptly removes these residues from the discharge port and other parts, preventing residue blockage of the discharge channel and ensuring the continuous and stable operation of the centrifuge.
