Abstract
The invention provides a precipitated sludge treatment system. The precipitated sludge treatment system comprises a sludge scraper and a precipitating tank, wherein two ends of a support frame and the sludge scraper are mounted on the edge of the precipitating tank; the top of a driving device is mounted in the middle of the support frame; a connecting shaft is mounted at the lower end of the driving device; a lifting device is mounted on the connecting shaft and can move up and down along the connecting shaft; three sludge scraping brackets are mounted on the lifting device and can move up and down along the lifting device, and the included angle between every two adjacent sludge scraping brackets is 120 degrees; sludge scraping plates are mounted at the lower ends of the sludge scraping brackets, and wheels are mounted on the tops of the sludge scraping brackets and can play a certain supporting role in the sludge scraping brackets; the horizontal height of the center of the bottom of the precipitating tank is larger than the horizontal height of the edge of the bottom of the precipitating tank, a sludge collection tank is arranged in the center of the bottom of the precipitating tank and is communicated with a sludge discharging pipe, and sludge is discharged through the sludge discharging pipe. A filter screen is mounted between every two adjacent sludge scraping brackets, so that the pollution caused after the sludge reenters water in the sludge scraping process is prevented.
Description
Technical field
The present invention relates to a kind of sewage deposit treatment system, particularly relate to a kind of precipitated sludge treatment system.
Background technology
Mud in sedimentation basin generally will be discharged by mud scraper.Mud scraper is used in the circular settling tank that in municipal sewage plant, waterworks and Industrial Wastewater Treatment, diameter is larger, gets rid of the scum silica frost in mud and the face, skim pond be deposited at the bottom of pond.The scraper arm of traditional mud scraper, cleaning shoe and adjustment lever etc. are all connected and fixed by gyration gear ring, make the load of gyration gear ring excessive, easily cause instability, and then increase is to the loss of machine volume.And cleaning shoe easily makes mud enter again in water when scraping mud, affect wastewater purifying efficiency.
Summary of the invention
The problem to be solved in the present invention is the scraper arm of mud scraper in precipitated sludge treatment system, cleaning shoe and adjustment lever etc. are all connected and fixed by gyration gear ring, make the load of gyration gear ring excessive, easily cause instability, and then increase is to the loss of machine volume.And cleaning shoe easily makes mud enter in water again when scraping mud, thus affect wastewater purifying efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of precipitated sludge treatment system, and this system is made up of circular settling tank and a mud scraper.Water inlet pipe is separately installed with, outlet pipe in circular settling tank.At the concavity of the bottom of circular settling tank, and dig out a mud-collecting slot, discharge pipeline and mud-collecting slot are connected.
The top of the drive unit of mud scraper is arranged on the central authorities of bracing frame, and the two ends of bracing frame are arranged on the edge of circular settling tank respectively.And drive unit is provided with a connecting axle, connecting axle stretches in sedimentation basin.The face of cylinder of connecting axle is provided with lowering or hoisting gear, and lowering or hoisting gear moves up and down along connecting axle.Three roots scraping mud support are arranged on lowering or hoisting gear, each other in 120 degree of angles, and move together along with the lifting of lowering or hoisting gear.Each below of scraping mud support is all provided with cleaning shoe, is scraping the top of mud support, is being provided with solid wheel, and wheel can provide support for the top of scraping mud support power, avoids the connecting portion scraping mud support and lowering or hoisting gear to cause damage owing to bearing a heavy burden excessive; Scrape between mud support screen pack is installed for every two.
Embodiments of the present invention will scrape mud support by lowering or hoisting gear to be raised up to top along connecting axle, now sewage put into from water inlet pipe circular settling tank and filter, after carrying out a period of time, by near for lowering or hoisting gear low side.Now start drive unit, connecting axle is rotated, and then drive lowering or hoisting gear and scrape mud support and rotate together, be arranged on the cleaning shoe scraping mud frame bottom just mud to be scraped bottom sedimentation basin, mud moves to the middle body bottom sedimentation basin due to Action of Gravity Field, and finally fall in mud-collecting slot, discharge along discharge pipeline.
The advantage that the present invention has and good effect are: by installing in screen pack can make mud be swept by cleaning shoe between mud support scraping again, again can not enter into water, greatly reducing water by the possibility again polluted.Installing wheel at the top of scraping mud support, can play certain supporting role to scraping mud support, reduce the heavy burden of scraping mud support and lowering or hoisting gear link position, proterctive equipment is without prejudice.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figure 1, in circular settling tank, be separately installed with water inlet pipe, outlet pipe and mud scraper.At the concavity of the bottom of circular settling tank, and dig out a mud-collecting slot 9, discharge pipeline 10 and mud-collecting slot 9 UNICOM.
The top of the drive unit 2 of mud scraper is arranged on the middle part of bracing frame 1, and the two ends of bracing frame 1 are installed in the edge of circular settling tank.And drive unit 2 is provided with a connecting axle 3, connecting axle 3 stretches in sedimentation basin.
The face of cylinder of connecting axle 3 is provided with lowering or hoisting gear 6, and lowering or hoisting gear 6 can move up and down on connecting axle 3.Scraping mud support 4 for three is arranged on lowering or hoisting gear 6, each other in 120 degree of angles, and moves together along with the lifting of lowering or hoisting gear 6.Each below of scraping mud support 4 is all provided with cleaning shoe 5, is scraping the top of mud support 4, is provided with solid wheel 8; Scrape between mud support 4 screen pack 7 is installed for every two.
Embodiments of the present invention will scrape mud support 4 and to be raised up to along connecting axle 3 below of drive unit 2 by lowering or hoisting gear 6, now sewage is put into from water inlet pipe circular settling tank to filter, after carrying out a period of time, lowering or hoisting gear 6 is fallen to least significant end.Now start drive unit 2, connecting axle 3 is rotated, and then drive lowering or hoisting gear 6 and scrape mud support 4 and rotate together, be arranged on the cleaning shoe 5 scraped bottom mud support 4 just mud to be scraped bottom sedimentation basin, mud moves to the middle body bottom sedimentation basin due to Action of Gravity Field, and finally fall in mud-collecting slot 9, discharge along discharge pipeline 10.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
