Description
Technical Field
The utility model belongs to the technical field of sludge dewatering, and particularly relates to a ring piece of a spiral-pile type sludge dewatering machine.
Background
The working principle of the spiral-pile sludge dewatering machine is that a fixed ring and a movable ring are mutually overlapped, and a spiral shaft penetrates through a filtering pushing device formed in the spiral shaft. The front end is a concentration part, and the rear end is a dehydration part. The pitch of the screw shaft is gradually reduced from the concentrating part to the dewatering part. 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.
The existing stacked spiral sludge dewatering machine adopts a gap between two fixed rings for moving the movable rings, and adopts a gap
The method for installing the small gaskets has the advantages that the number of the small gaskets is large, the installation labor intensity is high, in addition, the phenomenon of misloading or neglected loading easily occurs in the production, installation and after-sales maintenance processes, so that reworking is caused, the labor production efficiency is greatly reduced, the mass production and on-site maintenance work of equipment are extremely unfavorable, in addition, the fixed rings are usually a plurality of screws, and the adjacent fixed rings are easily spread.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model aims to provide the ring piece of the spiral sludge dewatering machine, which has high strength, long service life and easy installation and fixation.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the ring piece of the spiral-type sludge dewatering machine comprises a movable ring and a fixed ring, wherein a plurality of uniform ribs are arranged on two sides of the movable ring; the annular main body of the fixed ring is provided with a plurality of fixed lugs extending out of the annular main body along the circumferential direction, the fixed lugs are provided with bolt holes, the fixed lugs are also provided with fixed lug bosses protruding outwards along the direction perpendicular to the circumferential direction, and the fixed lug bosses are also provided with bolt holes corresponding to the bolt holes on the fixed lugs; each of the two sides of the fixed lugs is symmetrically provided with a plurality of supporting lugs, supporting lug bosses which are in the same direction with the fixed lug bosses along the direction perpendicular to the circumferential direction are arranged at the supporting lugs, a groove is formed in the other surface of each supporting lug, and protrusions corresponding to the grooves are arranged on the supporting lug bosses. The uniform ribs on the two surfaces of the movable ring ensure that the movable ring is not deviated between the two fixed rings, and the bending resistance of the movable ring is enhanced; the grooves of the supporting lugs and the protrusions of the supporting lug bosses can be correspondingly assembled together, so that two adjacent fixed rings are fixed and are not easy to open.
Further, the heights of the fixed lug boss and the supporting lug boss are the same.
Further, one or two supporting lugs are respectively and symmetrically arranged on two sides of the fixing lug.
Further, the fixing lug and the supporting lug are integrated.
Further, the fixed ear boss and the supporting ear boss are integrated.
Compared with the prior art, the utility model has the following beneficial effects: the uniform ribs on the two surfaces of the movable ring ensure that the movable ring is not deviated between the two fixed rings, and the bending resistance of the movable ring is enhanced; the grooves of the supporting lugs and the protrusions of the supporting lug bosses can be correspondingly assembled together, so that two adjacent fixed rings are fixed and are not easy to open.
