Abstract
The utility model discloses a kind of peripheral-traction logarithmic spiral mud scraper, its structure comprises mud-scraping apparatus, a kind of peripheral-traction logarithmic spiral mud scraper, its structure comprises service bridge and mud-scraping apparatus, described service bridge comprises crane span structure and is arranged on the electrical equipment on crane span structure, described crane span structure is movably arranged on center bearing bracket, and by the drive system driven rotary being arranged on periphery a kind of peripheral-traction logarithmic spiral mud scraper of the present utility model, has that energy consumption is low, little and that reliability is high advantage of wearing and tearing.
Description
Technical field
The utility model relates to a kind of mud scraper, particularly relates to a kind of peripheral-traction logarithmic spiral mud scraper.
Background technology
In sewage treatment unit, mud-water separation is carried out in the effect of secondary sedimentation tank (hereinafter referred to as second pond), through the precipitate and separate of second pond, mixed liquor is clarified, upper clear supernate is discharged, and the concentrated and backflow by isolated biological sludge, in second pond, along with area of passage increases, flow velocity reduces mud mixture, depositions settle in sewage is at the bottom of pond, mud scraper utilizes the scraper plate of truss lower end to be collected by the mud of precipitation, then it is discharged from sludge pipe, the operation conditions of second pond, the direct quality affecting biological treatment system effluent quality, from sedimentation effect, radical sedimentation basin can overcome the uneven shortcoming of rectangular sedimentation tank water distribution, in the selection of environmental protection industry (epi) especially sewage treatment process, the sedimentation effect of radical sedimentation basin is better than rectangular sedimentation tank and gains public acceptance.
The form of traditional and comparatively ripe radical sedimentation basin mud scraper is welded into array truss by angle steel to be suspended on below service bridge, with angle steel, truss and truss are connected into entirety at the scene during installation, 45 ° of tilting fixing cleaning shoes are hung below truss, by the driving mechanism that service bridge crane span structure two ends are arranged, drive the road wheel driven bottom end carriage, with the centre bearing of second pond central rotation bearing for the center of circle, circle being set up on the rail on sedimentation basin concrete platform, the scum silica frost in the mud at the bottom of pond and face, pond is collected and removed.This kind of mud scraper processing is comparatively simple, but there is following problem:
1. consumptive material is large, and especially during material selection stainless steel, cost compare is high;
2. scrape mud often to occur leaking mud, scraping the phenomenons such as mud is unclean;
3., when encountering obstruction when running, easily damage truss, cleaning shoe and each connector, also increase later maintenance, maintenance cost.
Utility model content
For solving the deficiencies in the prior art, the utility model specifically discloses a kind of peripheral-traction logarithmic spiral mud scraper, has that energy consumption is low, little and that reliability is high advantage of wearing and tearing.
The technical solution adopted in the utility model is as follows:
A kind of peripheral-traction logarithmic spiral mud scraper, its structure comprises service bridge and mud-scraping apparatus, described service bridge comprises crane span structure and is arranged on the electrical equipment on crane span structure, and described crane span structure is movably arranged on center bearing bracket, and by being arranged on the drive system driven rotary of periphery;
Described mud-scraping apparatus comprises logarithmic spiral shaped form scraper plate, collects the center mud-collecting slot of mud and hinged scraping arm by logarithmic spiral shaped form scraper plate, closed between described logarithmic spiral shaped form scraper plate, one end of described hinged scraping arm is fixedly connected with service bridge, the other end is fixedly connected with described logarithmic spiral shaped form scraper plate, and described center mud-collecting slot is arranged on the bottom of radical sedimentation basin.
Also comprise skimmer device, described skimmer device comprises the scum board being fixed on hinged scraping arm upper end, and one end of described scum board is arranged leads slag cylinder.
Also comprise downflow weir, described downflow weir top is fixedly connected with service bridge, and bottom is positioned at the bottom of radical sedimentation basin.
Described downflow weir is provided with the water inlet/outlet device for stationary flow, and described water inlet/outlet device comprises the water inlet straight cutting pipe arranged for water outlet after the stabilizing feed well of stationary flow and stationary flow outward.
Described center bearing bracket arranges rain cover.
The beneficial effects of the utility model:
1. hinged scraping arm can play cushioning effect, avoids the high strength rigid collision of moment, and protection scraping arm and cleaning shoe are not damaged, and cleaning shoe can be made not tilt, thus ensures not leak mud;
2. there is buffering between mud and scraper plate, pile up dense region when running into mud, alleviate the damage problem of the scraper plate that the recoil strength of mud to scraper plate causes, therefore, scraper thickness is more thinner than the thickness of traditional screeds, saves material, reduces cost.
3., owing to being closed between described logarithmic spiral shaped form scraper plate, can be avoided the weakness that non-closed cleaning shoe leaks mud.
Accompanying drawing explanation
