Abstract
Disclosed is a water distribution and sand draining equipment for a square advection sand sedimentation tank. One side of the sand sedimentation tank is provided with a water inlet ditch and the other side is provided with a water outlet ditch, a water outlet dam is arranged between the water outlet ditch and the sand sedimentation tank, a sand-scrapping harrow revolving around the tank center is arranged in the sand sedimentation tank, a scrapper is fixed on two arms of the sand-scrapping harrow, a dustpan-shaped small sand-scrapping hopper is arranged on the arm end, the scrapper is made of angle iron and a rubber of the same length with the scrapper is nailed on the lower chord. A shunt and guide plate is provided with the water inlet ditch in the inside, two rows of water-distribution grills are arranged on the inlet of the sedimentation tank and the water-distribution grill is a group of triangulate paling made of glass steel or timber after corrosion-resistant treatment. The water outlet dam is a hackle-shaped dam having the same width with the tank, the square sedimentation tank is square at the upper part and round at the lower part, one sand outlet is arranged on the tank side, the sand outlet is connected to the sand collection groove inbuilt with a submersible sewage pump, and a submersible sewage pump is connected to the dewatering screen. The device can adapt to the change of inlet water flow and the water distribution evenness is less influenced, thus ensuring the even water distribution. With good sand screening and dewatering effect, the device is a highly-efficient waste water treatment outfit.
Description
Technical field
The utility model relates to the water distribution of a kind of sewage disposal device, particularly settling pit and sediment outflow, sand setting dehydration equipment.
Background technology
Sand setting is the necessary pretreatment technology of any sewage work, in order that protect follow-up process facility, prevents to block and wearing and tearing.The square horizontal-flow grit chamber is a kind of novel settling pit, effect stability, the adaptation water yield that it has horizontal-flow grit chamber to have change advantages such as performance is strong, the pond is shallow, cost is low, simultaneously can adopt simple and reliable rotary harrow to get rid of sand grains, this advantage is that other type settling pit is not available.The sand setting water content is high to need dehydration be convenient to transportation, prior art be through swirler again by separation sieve or with rake reciprocal method such as raking dehydration on the inclined-plane sieve plate, the complicated cost height of equipment is safeguarded also complexity.Because of the pond long-width ratio is 1: 1, the water distribution uniformity difficulty is very big, and the flow deflector that external employing is established the close rotation adjusting water inlet water (flow) direction of putting of a row in import comes artificail commutation, makes it water distribution uniformity.But this rotation flow deflector is regulated very complicatedly, and adapts to the ability that current change.
Technology contents
The purpose of this utility model provides economic, simple and easy, a reliable water distribution uniformity of cover and a sediment outflow dehydration equipment, solves the even and sediment outflow dehydration equipment complicated problems of square settling pit cloth shipwreck.
The technical scheme of the utility model square horizontal-flow grit chamber water distribution sediment outflow equipment: square settling pit one side is provided with inlet channel, opposite side is provided with out water channel, go out between water channel and the settling pit and be equipped with effluent weir, settling pit is equipped with the sand scraping harrow around the rotation of the pond heart, it is characterized in that: inlet channel is built-in with shunting flow deflector, settling pit import the two water grids of arranging, effluent weir is the zig-zag weir wide with the pond, the square settling pit is a square top and round bottom, pool side has a sand export, be connected to sand catcher, the built-in submersible sewage pump of sand catcher, submersible sewage pump connects draining screen.
The shunting flow deflector is located on the channel central axis in the above-mentioned inlet channel, and it is equidistant that plate and both sides canal wall keep, and sheet material can be glass reinforced plastic or concrete.
Above-mentioned water distribution grid is by glass reinforced plastic or one group of rhizoma sparganic shape grizzly bar making through preservative-treated timber.
The material on above-mentioned zig-zag weir is a glass reinforced plastic.
Be fixed with scraper plate on the both arms of above-mentioned sand scraping harrow, there is dustpan-shaped small sand-scraping hopper the arm termination.
Above-mentioned scraper plate is made by angle steel, and its lower edge nail has and the isometric India-rubber strip of scraper plate.
Beneficial effect: the water distribution uniformity measure of square horizontal-flow grit chamber is that Parallel to the flow direction is established the shunting flow deflector on the canal axis in irrigation channel, plate hight is identical deeply with canal, it is two strands of current that current are divided equally, tentatively divide equally flooding velocity, in the settling pit import the two water grid grizzly bars of arranging are set again and carry out artificail commutation, consider out that stream also influences water distribution, so the pond is exported weir plate makes the sawtooth weir plate and makes water outlet even, to adapt to the variation of flooding velocity, make the degree of uniformity of water distribution be subjected to the influence of flooding velocity minimum, thereby guarantee that water distribution is even.
The pond shape of settling pit is a square top and round bottom, and the end is flat, and the sand grains that avales is harrowed it after pool side falls into sand export by the sand scraping harrow of centre-driven and flowed into sand catcher, is promoted to draining screen by the submersible sewage pump that is located in the sand collecting hopper again.Be fixed with several scraper plates and dustpan shape small sand-scraping hopper on the sand scraping harrow, this equipment dehydration, sludge discharge effects are improved, have characteristics simply and easily.Be applicable to sewage work's settling pit.
