Problems solved by technology

[0002] Sludge dehydration methods generally include centrifugal dehydration. Compared with sedimentation and other methods, centrifugal dehydration methods have the advantages of continuous operation and applicable to various sludges. However, centrifugal dehydrators have higher requirements on the purity of sludge. If The sludge contains hard impurities, which will damage the pipe wall and cause damage to the centrifugal dehydrator, and if the centrifugal dewatered sludge contains too much mineral or metal impurities, it will affect its subsequent treatment and utilization

Abstract

The present invention discloses an energy-saving sludge impurity removal dehydrator and a using method thereof. The energy-saving sludge impurity removal dehydrator comprises a shell, a first cavity with an upward opening is formed in the shell, a second cavity with a downward opening is formed in the rear side of the first cavity, and the first cavity is connected with the second cavity through a first through hole; and a third cavity communicating with the first through hole is formed in the right side of the first through hole. By arranging the screening device capable of screening the sludge, solid impurities in the sludge can be discharged out of the sludge treatment device, and the influence of the solid impurities on subsequent treatment of the sludge is reduced; the sludge dewatering device is provided with the centrifugal dewatering device, so that the water content of sludge can be reduced, and the transportation cost is reduced; and the sludge screening device is provided with the flushing device, the flushing device can work when the viscosity of sludge is high so as to guarantee normal work of the screening device, the flushing device is driven by a power source of the centrifugal dewatering device, sewage is recycled, and electric power and resource losses are reduced.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an energy-saving sludge removal and dehydration machine and a use method thereof. Background technique [0002] Sludge dehydration methods generally include centrifugal dehydration. Compared with sedimentation and other methods, centrifugal dehydration methods have the advantages of continuous operation and applicable to various sludges. However, centrifugal dehydrators have higher requirements on the purity of sludge. If The sludge contains hard impurities, which will damage the pipe wall and cause damage to the centrifugal dehydrator, and if the centrifugal dewatered sludge contains too much mineral or metal impurities, it will affect its subsequent treatment and utilization. Contents of the invention [0003] The object of the present invention is to provide an energy-saving sludge removal and dewatering machine and its use method, which are used to overcome the abo...
