Abstract
An arc-shaped scraper plate periphery transmission mud scraper is arranged in a circular precipitation tank body, and comprises a central slewing bearer, a plurality of working bridges surrounding the circular center of the slewing bearer and fixedly connected with the slewing bearer, road wheels arranged at the tail ends of the working bridges, driving motors for driving the road wheels and a flow guiding cylinder arranged under the central slewing bearer, the flow guiding cylinder is connected with a bottom end water inlet tube, the bottom end of every working bridge is provided with a truss, an upper scraper plate and a lower scraper plate arranged on every truss, the upper scraper plates are skimming plates, every upper scraper plate is arranged close to the water surface, a scum rake plate is arranged above every upper scraper plate, one side of the tank body corresponding to the scum rake plates is provided with a tubular residue discharging bucket, and a flushing device is arranged above the tubular residue discharging hopper; and the lower scraper plates are arranged at the tank bottom, the tank bottom is provided with a small mud bucket, every lower scraper plate comprises a long and narrow plate body with an arc-shaped section, the upper end surfaces of the plate bodies are connected with the corresponding trusses, and the lower end surface of every plate body is zigzag. The arc-shaped scraper plate periphery transmission mud scraper has the advantages of effective stability improvement, generation of a small stress by the scraper plates, low energy consumption, realization of long service life of the scraper plates, and high mud scraping efficiency.
Description
Technical field
The present invention relates to sewage treatment area, particularly relate to mud scraper.
Background technology
The peripheral drive sludge scraper of prior art is by driving reductor directly to drive road wheel, and drives the mud scraping truss scraper plate of service bridge and connection, pool side gradually scrape clarifier sludge to center set mud pit, under acting by external hydrostatic pressure, discharged outside pond by mud.Scum silica frost on the water surface between pool side and central draft tube is all scraped to pool side by scum silica frost scraper plate, relies on and scrapes slag rake and the cooperation of pipe draining slag bucket, and scum silica frost is scraped to pipe draining slag bucket, supernatant auto-flushing discharge outside pond.Its central draft tube is straight-tube shape, current stabilization poor-performing, the many employings of scraper plate are perpendicular to the form of sedimentation tank bottom surface, scrape the stress produced when mud rotates bigger, cause bigger energy consumption, and owing to scraper plate is straight plate, the difficulty inserting mud is bigger, easily cause bending or damage, being further improved.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that one is effectively improved stability, it is less that scraper plate produces stress, and energy consumption is relatively low, and scraper plate is long for service life, scrapes the circular arc scraper plate peripheral drive sludge scraper that mud efficiency is high.
For realizing the object of the invention, provide techniques below scheme: circular arc scraper plate peripheral drive sludge scraper, it is arranged in circular settling tank body, it is characterized in that including center steering bearing, around the pivoting support center of circle some the service bridges affixed with it, it is arranged at the road wheel of service bridge end, drive the driving motor of road wheel, it is provided with guide shell below center steering bearing, guide shell connects bottom water inlet pipe, described service bridge bottom is provided with truss, upper and lower two-layer scraper plate it is provided with on truss, upper scraping plate is skimming plate, upper scraping plate is disposed in proximity at the water surface, scum silica frost rake plate it is additionally provided with above upper scraping plate, cell body correspondence scum silica frost rake plate side is provided with pipe draining slag bucket, pipe draining slag bucket is provided above flusher；Described lower scraping plate is arranged at the bottom of pond, is provided with little bucket at the bottom of pond, and described lower scraping plate includes that strip plate body, plate body cross section are arc-shaped, and plate body upper surface is connected with truss, and lower surface is set to zigzag.
As preferably, lower scraping plate surface-coated has acid-resistant anti-corrosion coating.
As preferably, in lower scraping plate arc-shaped surface, it is provided with reinforcement gusset.
As preferably, central draft tube is up big and down small coniform cylinder, and the nearly upper end of cylinder offers pod apertures, and pod apertures aperture is 10 ~ 50mm, and barrel is provided with several stabiliers around the center of circle.
As preferably, described service bridge is set to 3.
The method have the benefit that the many employings of scraper plate of traditional peripheral drive sludge scraper are perpendicular to the form of sedimentation tank bottom surface, and my company uses arc-shaped structure, advantage of this is that: on the one hand, airflow design due to plate face, more meet fluid mechanics principle, it is greatly reduced because of scraping arm suffered stress of walking about on scraper plate plate face so that the risk that scraping arm distorts because moment of torsion is excessive is substantially reduced.On the other hand, scraper plate tangentially enters mud layer, mud can be shoveled to greatest extent, make mud flow downward along scraper plate curve, rapidly enter little bucket and drained by mud valve, so that the more aobvious quickness and high efficiency of the clarification of sedimentation tank, smooth linear type it mostly is bottom the scraper plate of traditional peripheral drive sludge scraper, my company then uses zigzag structure, such structure to make scraper plate be more easy to enter mud layer, scrapes mud more smoothly.
