A revolving foundation is arranged on the column tube in the middle of the tank, a driving machinery is arranged on one end of the aisle to drive the rubber wheel on the bridge frame to operate circularly along the aisle, a coupling beam is connected under the bridge frame, two to five supports are hinged under the coupling beam, arc-shaped and vertical steel mud scrappers are connected at the lower part of each support, the steel scrappers are supported by two idler wheels from the tank bottom, and the lower chords of the mud scrappers are connected with plastic mud scrappers. The bridge frame assumes an open-end slab structure with the side and lower surface closed. The mud scrappers are arranged in an arc shape with the arc heart facing the advance direction. A small windlass is fixed on the bridge frame, and the bridge frame and the support are connected with a sling. One layer of anti-corrosion protective film is coated on the surfaces of supports and mud scrappers immerged in waste water.
Description
Technical field
The utility model relates to a kind of sewage disposal device, and particularly a kind of settling tank is scraped mud equipment.
Background technology
Precipitation is the elementary cell of sewage disposal, no matter be that one-level is handled or the membrane process craft (TF/SC, BAF etc.) or all kinds of Activated Sludge Process of biological treatment all must have settling tank, circular settling tank is to use pond type the most widely.Existing circular settling tank is scraped mud equipment: the crane span structure two end supports has rotary support on the center stand column tube of pond on pond center stand column tube and pool side aisle, and aisle one end is provided with the rubber wheel that driving device drives on the crane span structure and moves along the aisle, makes circumferential motion; Scrape the mud main shaft by what drive unit drove circle centre position, direct-connected scraper arm at the bottom of the main shaft lower storage reservoir; Crane span structure is truss-frame structure, and string section can immerse in the water under the truss, is subject to the sewage corrosion.Scraper arm is the rigid structure around pond heart rotation, can not paste entirely at the bottom of the pond, and is easy to wear, and it is low to scrape mud efficient, easy-maintaining not also, and maintenance needs out of service.
Technology contents
The utility model will provide a kind of circular settling tank to scrape mud equipment, solves the problem that mud efficient is low, perishable, maintenance need be out of service of scraping.
The technical solution of the utility model: circular settling tank is scraped mud equipment, the crane span structure two end supports is on pond center stand column tube and pool side aisle, on the center stand column tube of pond, rotary support is arranged, aisle one end is provided with the rubber wheel that driving device drives on the crane span structure and moves along the aisle, make circumferential motion, it is characterized in that: below crane span structure, connect coupling beam, hinged two to five assistant supports in coupling beam lower end, every assistant support lower end connects the upright steel cleaning shoe of arc, the steel cleaning shoe by two roller Zhi Yuchi at the bottom of, the cleaning shoe lower edge connects plastic material and scrapes the mud bar.
Above-mentioned crane span structure is the upper shed plate case structure of side and following face closure.
The curved arrangement of above-mentioned cleaning shoe, arc core is towards advancing direction.
Fix little hoist on the above-mentioned crane span structure, link to each other by hoist cable between support and the little hoist.
Above-mentioned support and the cleaning shoe surface that is immersed in sewage scribbles the anti-rotten protective membrane of one deck.
Beneficial effect: crane span structure is erected on center, pond barrel mast and the pool side aisle, and pool side aisle one end is equipped with driving device makes rubber wheel move along the aisle, and its track is for being the circumference in the center of circle with the center, pond.The crane span structure of upper shed closure plate box structure is entirely on the water surface, and is not perishable, can not emptying pond in sewage keep in repair, and than the crane span structure of truss also economical with materials and processing charges.
Crane span structure one side mounting cleaning shoe support, number is decided on the pond diameter, drags the cleaning shoe of arc shooting, and mud is scraped to the center, pond.Each support drags a cleaning shoe, cleaning shoe and support are with being hinged, cleaning shoe fluctuates around hinge, and the cleaning shoe main body is an arc steel cleaning shoe, the steel cleaning shoe by two roller Zhi Yuchi at the bottom of, leaning on roller to roll when scraping mud advances, steel cleaning shoe lower edge is that plastic material is scraped the mud bar, can bow and paste at the bottom of the pond, and support is that folding structure is fixed on the crane span structure, little hoist is carried to crane span structure and being keeped in repair on the available crane span structure, need not emptying out of service pond.If be used for secondary sedimentation basins and the flocculation sedimentation tank rigidity cleaning shoe that then can directly overhang from the crane span structure, impel sludge stream to relief outlet.The utility model is applicable to the circular sedimentation basin of sewage disposal of all kinds of activated sludge processes.
