Abstract
The utility model discloses a hydraulic-drive tank bottom mud scraper and relates to tank bottom sludge removal equipment in petroleum and petrochemical industry and other wastewater treatment industries. The hydraulic-drive tank bottom mud scraper comprises a central fixed seat mounted at the bottom of a tank body, wherein a rotating ring is arranged on the central fixed seat through a sliding bearing, and two groups of trusses are hinged to the rotating ring; the lower part of each group of trusses is connected with a scraper blade, one end, far away from the rotating ring, of each group of trusses is connected with a walking vehicle, and the lower part of each walking vehicle is connected with a roller through a roller shaft. The tank bottom mud scraper further comprises a hydraulic drive device, and the hydraulic drive device drives the two groups of trusses to rotate. Compared with the conventional tank bottom mud scraper, the hydraulic-drive tank bottom mud scraper adopts hydraulic drive to replace motor drive, the drive device is mounted outside the tank not inside the tank, and a drive shaft is removed, so that the drive safety is ensured, and processing and maintenance are easy.

Technical field
The utility model relates to the removing equipment of mud at the bottom of petroleum and petrochemical sector and other sewage treatment industry tank.
Background technology
The outside reductor drive shaft of the many employings of mud scraper at the bottom of tank at present, drive central gear to rotate to drive the mode of scraping arm to scrape mud, this mud scraper is owing to adopting long shaft transmission, transmission is unstable, in the time of major diameter tank body operating mode, due to the very large moment of torsion of needs, cause major axis processing difficulties, simultaneously because rotating shaft and tank body need to adopt sealing, owing to being full of sewage in tank, hermetic unit is revealed and cannot be keeped in repair.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and mud scraper at the bottom of a kind of hydraulic-driven tank is provided, and processing is simple, easy to maintenance, drives and tank body does not need to adopt airtight and watertight padding, solution leakage problem.
The purpose of this utility model is achieved in that mud scraper at the bottom of a kind of hydraulic-driven tank, comprise the center holder that is arranged on tank base, on the holder of center, by sliding bearing, rotating ring is set, hinged two groups of truss on rotating ring, the below of every group of truss connects respectively scraper plate, every group of truss connects respectively moving trolley away from one end of rotating ring, the below of each moving trolley connects roller by roller shaft respectively, at the bottom of described tank, mud scraper also comprises fluid pressure drive device, and fluid pressure drive device drives two groups of truss to rotate; Described fluid pressure drive device comprises the Hydraulic Station being arranged in outside tank body, Hydraulic Station connects hydraulic supply line, the output of hydraulic supply line connects two hydraulic pressure by swivel joint and is in charge of, the every output connecting fluid pressure motor respectively that hydraulic pressure is in charge of, the output of every hydraulic motor is connected with described roller shaft respectively.
The moving trolley roller on hydraulic motor of the present utility model and truss top is coaxially installed, when work, Hydraulic Station drives hydraulic motor rotation, hydraulic motor drives the moving trolley roller rotation that is arranged on truss top, roller rotarilys actuate truss and rotates around center holder, truss bottom install scraper plate, scraper plate by tank at the bottom of sludge scraping to center bucket or tank limit bucket, by discharge pipeline by outside mud drain tank.
?compared with mud scraper at the bottom of former tank, the utility model adopts hydraulic drive to replace motor-driven, and transmission device is gone to outward in tank by tank, has cancelled driving shaft, has ensured the safety of transmission, and processing, maintenance are also simple.
?fluid pressure drive device of the present utility model comprises the Hydraulic Station being arranged in outside tank body, Hydraulic Station connecting fluid pressure pipe, the output connecting fluid pressure motor of hydraulic tube, the output of hydraulic motor connects pinion, in described rotating ring, internal tooth is set, pinion is meshed with the internal tooth of rotating ring.Hydraulic motor is arranged on center support, fluid motor-driven pinion rotation, the internal tooth of pinion drive rotating ring, rotating ring is rotated, drive centre mount rotation, scraper plate is installed in truss bottom, scraper plate by tank at the bottom of sludge scraping to center bucket or tank limit bucket, by discharge pipeline by outside mud drain tank.
