Description
Technical field
The utility model is related to a kind of technical field of sewage, and in particular to single tube scraping and sucking machine.
Background technology
Circular settling tank is water treatment building common in water treatment process, such as round primary sedimentation tank, round secondary settling tank.
Its operation principle is：Active sludge intermixture uniformly flows into circular settling tank, and activated sludge is deposited in circle under gravity
Shape sedimentation basin bottom is discharged through sludge pipe outside pond, and the supernatant separated is excluded through outlet pipe outside pond by the effluent trough of pool side.
To exclude the sludge at sedimentation basin bottom in time, ensure that the normal operation of sedimentation basin, sedimentation basin are generally configured with spoil disposal
Machinery.Currently used spoil disposal machinery has mud scraper, suction dredge two major classes.Mud scraper is by mud with hanging plate along bottom of pond scraping delivery to row
Mud mouth；Suction dredge is that mud intake line is discharged by pipeline outside pond.Sedimentation basin is main group of activated sludge sewage disposal technology
At part, be generally used for by sewage suspended matter or activated sludge precipitate, have reached clarification water quality purpose.According to
The difference of the kind of drive can be divided into peripheral-traction scraping and sucking machine and center driving scraping and sucking machine.
Center driving scraping and sucking machine is mainly by electrfic centre driving device（Motor and motor reducer）, mud-collecting slot, dredging tube,
Center bearing bracket, work beam（Spread out frame, service bridge, center inspection platform）, band steel drag-line and electric control system composition.Center
Holder is the major support members of whole equipment, is fixed in circular settling tank pond, and top is equipped with centre-drive device.Collection
Below the centrally disposed holder of mud groove, dredging tube sum aggregate mud cylinder passes through band steel zipper simultaneously by flanged joint, dredging tube distal end
