The rotation of the screw shaft drives the movable ring to clean the filter gap continuously while pushing the sludge from the concentration part to the dehydration part, so as to prevent blockage. The sludge is transported to the dehydration part after being concentrated, and the sludge is gradually reduced along with the filtration gap and the screw pitch in the advancing process, and under the action of the pressed plate, the extremely large internal pressure is generated, the volume is continuously reduced, and the purpose of full dehydration is achieved.
At present, in actual use, due to improper operation or diversified sludge characteristics, sludge blocking phenomenon is generated in a spiral body dehydration section, namely, sludge is adsorbed on a spiral shaft and rotates along with the spiral shaft, and due to limited spiral body accommodating cavities, the larger the amount of sludge is, the larger the internal pressure is generated, the more easily the sludge is hardened into blocks, the sludge can be extruded out of a ring piece gap, and even the spiral body stacking machine cannot normally complete dehydration work.
After the shaft is blocked by sludge, the internal pressure of the spiral stacking body is increased, and the contact abrasion of the spiral blade and a conventional movable ring is accelerated, so that the whole service life of the spiral stacking sludge dehydrator is shortened; meanwhile, the output torque of the speed reducer is increased due to the increase of the internal pressure, and the service life of the speed reducer is shortened.
At present, the speed reducer is required to be disassembled for the treatment of the blocking shaft, the screw shaft is extracted, hardened sludge is cleaned, and then the speed reducer is reinstalled. The on-site working conditions are different, the types of the stacked screws are different, the operation difficulty is high, the disassembly operation can be finished only by means of a crane, and the labor intensity of workers is high.
