Abstract
The invention discloses a mud scraper for an advective floatation tank, which comprises a speed reducer, traction chains, a sprocket device, a mud scraping board, a lifting device and a joist barrow, and is characterized in that the traction chains on two sides of the mud scraper respectively are used for traction of the joist barrow, two ends of the traction chains are fixed onto driven sprockets in the front and in the rear of the mud scraper respectively, the lifting device is connected to the rear end of the joist barrow, the mud scraping board is connected to the lower end of the lifting device, and a pneumatic device is used for controlling perpendicular lifting of the lifting device. The mud scraper for the advective floatation tank is simple in structure, easy in assembly and maintenance and convenient in control, the two sides of the mud scraper can be kept to march forward synchronously by means of chain drive, and 'rail chewing' 'sideslip' and 'derailing' of steel wheels of the joist barrow are avoided. Besides, the pneumatic device is used for controlling lifting of the mud scraper and can ascend and descend at any time, so that mud scraping time is shortened, mud scraping efficiency is improved, stirring of mud layers is reduced, and the influence on effluent quality is weakened.
Description
Technical field
the present invention relates to a kind of sewage disposal device, are specifically related to a kind of mud scraper of novel advection flotation tank.
Background technology
air-float technology is low, simple to operate with its technology maturation, small investment, cost, preliminary treatment efficient high, and is widely used in the preliminary treatment and the advanced treating of wastewater treatment.At present the flotation tank structure is divided into flat flow and vertical-flow two kinds.
flat flow flotation tank is present the most frequently used a kind of form; Its reaction tank and flotation tank are built jointly; After waste water entering reaction tank mixes fully; Get into contact chamber to prolong the time of contact of flco and bubble through baffle plate, get into the separation chamber by top, contact chamber then and carry out the solid-liquid separation.Pond face mud scum is scraped the dreg collecting slot like the flotation tank rear end by mud scraper, and clear water is discharged by the bottom water leg.
traditional advection flotation tank mud scraper adopts to adopt steel wheels and guide rail transmissions more, and drive unit is installed in above the car of purlin, drives steel wheel and rotates, and the frictional force drive purlin car between dependence steel wheel and guide rail advances and retreats.Cleaning shoe relies on manual work to dig, put down.In use, there is following problem:
The vibrations of
(1) process, natural effects such as Exposure to Sunlight, burn into temperature Change, guide rail deforms, and makes steel wheel that " gnawing rail " phenomenon take place in traveling process, directly causes steel wheel locking or derailing.
(2) steel wheel or guide rail surface have water stain or when having mud to adhere to; Frictional force between steel wheel and the guide rail descends; Cause car one side steel wheel in purlin " to skid " in the original place and can not advance or retreat, and possibly cause the non-slip steel wheel derailing of opposite side.
(3) cleaning shoe descends to beginning to scrape mud or scrape and rises after mud finishes, and has the hysteresis of a period of time, causes scraper plate bigger to the stirring of mud layer, causes air supporting water outlet band mud easily, influences effluent quality.Therefore, a kind of design science, simple to operate, reasonable and practical novel flotation tank mud scraper become a kind of necessary.
Summary of the invention
the present invention seeks to: a kind of novel mud scraper that is applicable to the advection flotation tank is provided, can realizes that mud scraper two lateral balances move, and can realize the instant lifting of cleaning shoe and descend.
Technical scheme of the present invention is:

are further, are provided with drive sprocket in the middle of the said driving shaft, and said reductor one end is connected with the reductor sprocket wheel, and said drive sprocket links to each other with the sprocket wheel of said reductor through driving chain.
are further, and said lowering or hoisting gear is made up of cylinder frame and cylinder, and said cylinder frame is fixed on the mud scraper through set screw, and an end of said cylinder is fixed on the said cylinder frame; On the said cylinder magnetic valve is housed and controls up-down.
The up-down of cylinder relies on the compressed-air actuated break-make of solenoid control, to realize the up-down of cleaning shoe
are further, and described cleaning shoe top is fixed on one section horizontal band steel, and said band steel is connected in said lowering or hoisting gear.
are further, and described band steel both sides are provided with the inverted triangle body draw-in groove that agrees with mutually, as the stressed and positioner of cleaning shoe for the inverted triangle body of protrusion under the said inverted triangle body.
are further, and said inverted triangle body draw-in groove is fixed on the car of purlin through set screw, through adjusting set screw with adjustment draw-in groove height.
The distance of cleaning shoe and mud face can be adjusted through the height of adjustment cylinder frame and inverted triangle body draw-in groove in
, the degree of depth of scraping mud during with control cleaning shoe decline work.
are further, and cleaning shoe is processed by two corrosion resistant plates up and down, and the angle of top and mud layer is 90 °, and the angle of bottom and mud layer is 75 °.
?
Advantage of the present invention is:
this novel advection flotation tank mud scraper is simple in structure, is easy to assembling and safeguards that control is convenient, adopts chain drive, keeps advancing synchronously of mud scraper both sides, has avoided that purlin car steel wheel " is gnawed rail ", " sideslip ", " derailing " phenomenon; Adopt the up-down of pneumatic means control cleaning shoe simultaneously,, can realize the up-down of pneumatic means at any time no matter the purlin car is stopping or travel condition; Shortened greatly and scraped the mud time; Improved and scraped mud efficient, and reduced stirring, reduced influence effluent quality to mud layer.
