Description
Technical field
The utility model relates to a kind of sewage-treatment plant, especially relates to a kind of aerated grit chamber.
Background technology
Existing aerated grit chamber mainly is the eddy flow generation washed-out sand effect that forms water by aeration, to improve desanding efficiency and organic separative efficiency.But existing aerated grit chamber is because swirl velocity is difficult to mensuration in practical operation, can only control swirl velocity by regulating aeration rate, but the adjusting of aeration rate is difficult grasp also, although the excessive sand grains of having rinsed well of tolerance, but can reduce the clearance of tiny sand grains, tolerance is too small can't to guarantee enough swirl velocities again, does not have the effect of aeration.And aerated grit chamber can cause certain pollution to air and environment, can produce pernicious gas and contaminated environment in the desanding process.
The utility model content
In order to solve deficiency of the prior art, the utility model provides a kind of aerated grit chamber, has overcome in the prior art bad control owing to aeration rate and has reduced except sand coarse aggregate ratio pair, has improved the efficient to sewage disposal.
The technical solution of the utility model is as follows:
A kind of aerated grit chamber, comprise aeration tube, setting pot and sand collecting hopper, it is characterized in that: it also comprises inhales sand mouth, sand suction pipe, collection sand device and sediment outflow pipe, wherein inhales the bottom that the sand mouth is located at sand suction pipe, collection sand device is located at the top of sand suction pipe, and the sediment outflow pipe is connected on the collection sand device.
Further, also be provided with stirring vane, bearing arrangement and drive unit on the described sand suction pipe, stirring vane is located on the sand suction pipe of sand collecting hopper top, and bearing arrangement is located at the below of collection sand device, and bearing arrangement is connected the conducting wire with drive unit and connects.
Further, an end of described sediment outflow pipe is provided with sand export and sediment outflow switch.
Further, described setting pot is provided with Sha Chigai.
Further, be provided with the sand car below the described sediment outflow pipe.
Compared with prior art, the beneficial effects of the utility model are, the sand suction pipe that adopts, collection sand device and sediment outflow pipe can better be discharged the sand setting of setting pot bottom, the stirring vane that adopts can make the aeration desanding combine with the stirring desanding, avoided being difficult to control the problem except the sand coarse aggregate ratio reduction that causes because of aeration rate, improved except sand coarse aggregate ratio, and can reduce and tune up simply the air pollution problems inherent that aeration rate causes, set sediment outflow switch and sand car can be controlled arranging what time, avoid the long-pending sand of setting pot too much to affect except sand coarse aggregate ratio, the Sha Chigai that adopts, can prevent that the toxic gas after the aeration desanding from directly contacting whole aerated grit chamber simple installation, processing ease with air, improve the efficient of sewage disposal, prevented the environmental pollution in the sewage disposal process.
