Description
Technical Field
The invention relates to the technical field of environment-friendly water treatment, in particular to a center-driven mud scraper and a water treatment sedimentation tank.
Background
The sedimentation tank is indispensable basic equipment in production processes of sewage treatment, water works, mineral separation and the like, and the principle of gravity sedimentation is utilized to reduce the flow velocity of water in a larger tank body space so as to enable the water to approach to smooth laminar flow, thereby endowing free sedimentation time to particles and realizing solid-liquid separation.
Whether the sludge is discharged smoothly is directly related to the water purification effect of the sedimentation tank, and when the sludge is not discharged smoothly and sludge is deposited too much, the water quality of the discharged water is seriously influenced. Bridge type mud scrapers, central rotating mud scrapers and peripheral driving mud scrapers are three kinds of common mud discharging equipment. Whether the sludge is discharged smoothly is directly related to the water purification effect of the sedimentation tank, and when the sludge is not discharged smoothly and sludge is deposited too much, the water quality of the discharged water is seriously influenced.
The sedimentation tank is usually rectangular or circular, although the rectangular tank is compact in layout and saves occupied land, dead corners exist at two ends of the tank body due to the operation mode of the truss vehicle or the chain plate type mud scraper, silt accumulation is easy to cause, the mud body is easy to float upwards due to the overlong tank body, and the mud scraping effect is poor; although the circular pool has the characteristics of good water conservancy characteristic, excellent mud-water separation effect and the like, the areas of four corners of the circular pool cannot be fully utilized, enough space needs to be reserved for adjacent arrangement, the occupied area is large, the amount of water treated by the same occupied area is small, and the construction investment is large. When the circular tank body and other unit tank bodies are arranged, a large amount of land area is wasted between the circular tank body and other unit tank bodies, and connecting pipelines between the circular tank body and other unit tank bodies are increased.
The existing foreign and domestic related enterprises design the sedimentation tank with the square structure respectively, compared with the existing rectangular and circular sedimentation tanks, the hydraulic characteristic of the square tank is better, the four corners can be collided to generate turbulent flow to strengthen the coagulation reaction, compared with the circular structure, the civil engineering cost is saved by more than 25%, the volume of the tank is increased by 28%, the strength of the tank is better, and the water treatment effect is better.
However, when the central rotary type mud scraper is applied to a square sedimentation tank, sediment at corners cannot be cleaned.
The Chinese patent with patent number 200510094705.5 discloses a mud scraping device for a water treatment sedimentation tank, which can realize rotary mud scraping for a square mud-water separation tank. However, when the four-bar mechanism composed of 4 bars rotates to four corners of a square, the radial distance is suddenly increased, so that the auxiliary scraping arm of the parallelogram four-bar mechanism suddenly and rapidly extends out, and the speed jump occurs four times after one rotation. Uneven quick sudden jump can make the rotation scrape mud operation inhomogeneous, easily causes to deposit the active sludge layer and stirs in disorder firstly to make originally collect the active sludge in the scraper blade lower part, can consequently suddenly stretch out the sudden jump fast, cause gathering active sludge's scattering, the mud layer is chaotic, strikes off bottom sediment mud less, is unfavorable for depositing mud with square pond four corners and hangs the collection to the bottom of the pool center and discharge, thereby influences mud-water separation effect and efficiency.
The Chinese patent with application number 201510297588.6 discloses an automatic telescopic scraping arm of a mud scraper for a regular polygon settling tank, which adopts a combined design of a middle fixed scraping arm and two side automatic telescopic scraping arms, but the scheme is easy to block at the positions of four corners at the bottom of the tank, and simultaneously, because the two side automatic telescopic scraping arms and the fixed scraping arms belong to a split structure, the working stability is poor, the automatic telescopic scraping arms are easy to damage, once the settling tank is required to stop working during maintenance or replacement, the water treatment efficiency of the whole sewage treatment plant is influenced. When the cantilever beam structure of the single-sided metal frame fixed scraping arm of the whole mud scraper bears great resistance in a sedimentation tank, particularly when the cantilever beam structure faces the blockage at the four corners of the bottom of the tank, the beam structure is easy to break.
To this end we propose a centrally driven mud scraper and water treatment settling tank to solve the above problems.
