Abstract
The utility model discloses a continuous flushing sand filtering device with stable-flow sand settling function, comprising a center sand lifting pipe, a folding plate sand washing device and a sand washing sewage area, wherein a hopper-shaped stable-flow sand settling device is arranged in the sand washing sewage area, and the lower part thereof is communicated with the center sand lifting pipe and the folding plate sand washing device; the sand washing sewage area is connected with a sand washing sewage outlet pipe; the bottom of the hopper-shaped stable-flow sand settling device forms a slope shape, or an inverted cone shape; and the top of the hopper-shaped stable-flow sand settling device is provided with a water outlet weir. As the bottom of the hopper-shaped stable-flow sand settling device is the hopper-shaped slope, the filtered sand can smoothly flow into the folding plate sand washing device, and cannot accumulate around the folding plate sand washing device, thereby preventing the filtered sand loss. The water outlet weir at the top of the hopper-shaped stable-flow sand settling device leads the water flow to be uniform and stable, so that the utility model avoids the phenomenon that the sand flows away along with the sand washing sewage due to poor sand filtering and settling condition caused by unstable water flow.
Description
Technical field
The utility model belongs to field of environment engineering, particularly a kind of continuous flushing sand filtering device with current stabilization sand setting function.
Background technology
The flushing sand filtering device is mainly used in advanced treatment of wastewater continuously.Municipal wastewater advanced treating and Industrial Wastewater Treatment have been widely used at present at home and abroad.
Existing continuous flushing sand filtering device can satisfy the needs of advanced treatment of wastewater substantially, referring to Fig. 1 and Fig. 2, the process of the washed-out sand of flushing sand filtering device and washed-out sand sewage discharge is as follows continuously: contaminated filter sand is carried to center sand extraction tube 1 top by gas along center sand extraction tube 1 bottom, then fall after rise to the flap sand-washing device 2 of sand developing tube periphery, center, and rely on gravity to fall along the flap of flap sand-washing device 2, in the filter tank, form sand filter blanket 5; Water enters from sand filter water inlet 6, circulate the back from 7 outflows of sand filter delivery port, in the filter tank in the filter back clear water zone 4 clear water rely on the difference in height of clear water liquid level and washed-out sand effluent outfall 3 in the ponds, thereby will clean up along filter sand along flap sand-washing device 2 is upwards mobile from flap sand-washing device 2 whereabouts.Washed-out sand sewage enters 8 backs, washed-out sand contraminated zone and discharges outside the pond from washed-out sand effluent outfall 3.
The washed-out sand effluent outfall is that two short tubes and peripheral base are levels, and washed-out sand sewage is discharged outside the pond by interior two short tubes in zone.There are two shortcomings in this technology.At first, because the bottom is a level, around the washed-out sand effluent outfall, have filter sand and can not fall back to layer of sand along sand-washing device timely at bottom precipitation, pile up more for a long time when sand, can be poured in the washed-out sand effluent outfall, cause the loss of filter sand by the rinse water from sand-washing device to the upper reaches.Secondly, rely on discharge of pipes washed-out sand sewage, can cause turbulent flow and whirlpool in washed-out sand sewage zone, be unfavorable for falling into sand-washing device smoothly from the sand that the center sand extraction tube comes out, a part of filter sand can be poured the loss that causes filter sand in the washed-out sand effluent outfall by washed-out sand sewage.Therefore continuous flushing sand filtering device of the prior art can not solve the problem that sand filtering device top filter sand runs off with recoil waste water.The loss of filter sand is the major issue of washing sand filtering device continuously.Want regular stop-off to cause artificial and waste economically on the one hand.Filter sand can cause sand to deposit blocking pipe in pipeline after with washed-out sand sewage inlet pipe road on the other hand.Also can cause wearing and tearing when filter sand enters follow-up washed-out sand sewage disposal device, cause service life of equipment to reduce or directly damage process equipment.
The utility model content
The utility model provides a kind of continuous flushing sand filtering device with current stabilization sand setting function that can prevent that filter sand runs off in order to solve the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of continuous flushing sand filtering device with current stabilization sand setting function, comprise the center sand extraction tube, be arranged on the outside flap sand-washing device in center sand extraction tube upper end and be located at the washed-out sand contraminated zone at sand extraction tube top, center, described washed-out sand contraminated zone is provided with bucket-shaped current stabilization sand setting device, described bucket-shaped current stabilization sand setting device bottom communicates with described center sand extraction tube and described flap sand-washing device, and described washed-out sand contraminated zone connects the washed-out sand effluent outfall.
