Description
Technical field
The utility model relates to a kind of field of sewage treatment equipment, is specially a kind of circular arc scraper plate lifting center drive mud-scraper.
Background technology
Mud scraper is a kind of soil discharging facility, in the circular settling tank that diameter in municipal sewage plant, waterworks and Industrial Wastewater Treatment is larger, gets rid of the scum silica frost in mud and the face, skim pond be deposited at the bottom of pond.Its operation principle is that drive unit drives mud scraper around sedimentation basin central rotation, and former water is after sedimentation basin precipitation, and supernatant is discharged from overflow weir, be deposited in the mud at the bottom of pond, under the promotion of scraper plate, lentamente along pond underflow in central mud-collecting slot, discharged by discharge pipeline.Face, pond scum silica frost focuses on the region between scum silica frost scraper plate and scum board simultaneously, and when service bridge is through floating over the scum silica frost expelling tube in face, pond, under scum silica frost expelling tube is forced into liquid level, scum silica frost is discharged outside pond by expelling tube.The many employings of scraper plate of traditional circular arc scraper plate lifting center drive mud-scraper, perpendicular to the form of sedimentation basin bottom surface, because scraping arm walks about suffered force rate comparatively greatly on this form scraper plate plate face, make scraping arm easy distortion because moment of torsion is excessive.When collect mud long mud thicker or downtime harden collection time, mostly be smooth linear pattern bottom the scraper plate of traditional circular arc scraper plate lifting center drive mud-scraper, such structure scraper plate is not easy to enter mud layer, thus the effect of mud is scraped in impact.
Summary of the invention
The purpose of this utility model is, for the problem such as existing scraper plate shape and scraper plate placement form pointed in background technology, to provide a kind of circular arc scraper plate lifting center drive mud-scraper that can solve foregoing problems.
For realizing the purpose of this utility model, there is provided following technical scheme: a kind of circular arc scraper plate lifting center drive mud-scraper, it comprises support, slop pail, service bridge, main driving motor, Minus speed machine, center driving axle, flocculation stirring machine, flocculation cylinder and scraping arm, described service bridge is arranged on the top of slop pail, slop pail is arranged on support, a circle downflow weir is with around slop pail, the middle part of service bridge is provided with center support, described main driving motor and reductor are fixed on center support, the both sides of center support are respectively arranged with flocculation stirring machine, flocculation stirring machine lower end connects agitating device, agitating device is inserted in flocculation reaction bucket, water inlet pipe is provided with between service bridge and slop pail, water inlet pipe outlet is inserted in flocculation bucket, the side wall upper part of slop pail is provided with downflow weir outlet, the output shaft of motor is connected with reductor, the output shaft of reductor connects center driving axle, the base plate of described slop pail is conical bottom board, the drift angle of conical bottom board is arranged downwards, the corner position of conical bottom board is provided with to recessed mud collecting cavity body, mud collecting cavity body is the cavity of taper, the bottom that center driving axle lower end extends to mud collecting cavity body is connected with base bearing, the sidewall of mud collecting cavity body is provided with spoil disposal pipeline, described scraping arm is connected to the middle and lower part of center driving axle, and be arranged on the top of conical bottom board, the bottom of scraping arm connects scraper plate, it is characterized in that described scraper plate adopts arc-shaped structure, it is zigzag bottom scraper plate, scraper plate is provided with corrosion-inhibiting coating.
On such scheme basis, particularly, described scraping arm has 3 groups, and often group is spaced apart 120 °, fixes between scraping arm and scraper plate with clamping screw.
In order to make to discharge in mud from spoil disposal pipeline, described center driving axle bottom is provided with low scraper plate, and low scraper plate is arranged in mud collecting cavity body, and center driving axle lower end is connected with base bearing.
In order to shovel mud to greatest extent, described scraper plate tangentially enters mud layer.
In order to make scraper plate more easily enter mud layer, be zigzag bottom described scraper plate.
In order to enable scraping arm and center driving axle connect securely by, described scraping arm through the hole on center driving axle, and being provided with aperture scraping arm lengths 2/3 place, being connected with center driving axle by aperture steel wire rope, steel wire rope is provided with elasticity adjusting mechanism.
In order to be that circular arc scraper plate lifting center drive mud-scraper operating room is more firm, described support comprises multiple leg, arranges steel reinforced concrete basis below each leg.
The beneficial effects of the utility model: the utility model overcomes the deficiency of existing center driving bagger scraper plate shape and erection mode etc., proposes a kind of circular arc scraper plate lifting center drive mud-scraper being equipped with circular arc scraper plate.The circular arc scraper plate lifting center drive mud-scraper of circular arc scraper plate, due to the airflow design in plate face, more meets fluid mechanics principle, because scraping arm suffered stress of walking about greatly reduces on scraper plate plate face, the risk of scraping arm distortion because moment of torsion is excessive is reduced greatly.On the other hand, scraper plate tangentially enters mud layer, can shovel mud to greatest extent, and mud is flowed downward along scraper plate curve, enters little bucket fast and is drained by mud valve, thus makes the more aobvious quickness and high efficiency of the clarification of sedimentation basin.In addition, circular arc scraper adopts carbon steel anti-corrosion material, on the one hand, due to the reduction of resistance to water-flow, can adopt thinner lighter steel sectional material, make novel mud scraper more aobvious than traditional mud scraper light, reduce material cost; On the other hand, light structure makes the moment of torsion of scraping arm further reduce, thus reduces the use power of mud scraper, and the operating cost of sedimentation basin is greatly reduced.Be zigzag structure bottom scraper plate, such structure makes scraper plate more easily enter mud layer, scrapes mud more smooth and easy.Scraping arm adopts 3, and such structure makes cleaning mud more thorough, and it is higher to scrape mud efficiency.
