Description
Technical field
The present invention relates to a kind of water treatment facilities, particularly a kind of Automatic continuous cleaning and filtering quicksand device.
Background technology
The existing equipment for Water treatment filtration, major part is fixed filter bed, and need regular stop cleaning to remove trapped substance, often need many complete equipments to run together, the impact that power generating ratio brings, equipment investment amount is large, returns Operation and Maintenance and brings impact.The existing filter of major part only has removes suspended solids effect, does not but remove effect to the organic matter in water body.
Summary of the invention
The object of the invention is the defect for existing in prior art, a kind of Automatic continuous cleaning and filtering quicksand device is provided.The present invention is a kind of filter of flow-type circulation filter bed, can realize filtration limit, limit and automatically clean, possess the organic matter in certain removal sewage and denitrification functions simultaneously.
The present invention mainly comprises: filtration fraction and washed-out sand part, filtration fraction is by tank body, water-locator, sand distributor, sand collecting chamber forms, washed-out sand part is by carrying sand pump, sediment transport pipe, sand-washing device forms, it is characterized in that described filtration fraction is connected with washed-out sand part is that a worry sand is by flowing from top to bottom, waste water from bottom to top completes the loop structure up and down of filtration, tank body top is cylindrical, bottom is turbination, sand distributor is arranged on the bottom of tank body, water-locator is arranged on above sand distributor, be connected with water inlet pipe, sand distributor is the circular cone such as body such as grade of two docking, all pointed in circular cone up and down, sand body can be made to fall the moment be from top to bottom uniformly distributed, sand local deposits can not be caused.Tank body conical lower section is provided with sand collecting chamber, the outlet of sand collecting chamber is connected with sediment transport pipe, and the other end of sediment transport pipe is connected with the sand-washing device entrance at tank body top, is provided with and carries sand pump in the middle of sediment transport pipe, consider sand and finally fall into sand trap, by sediment transport pipe with carry sand pump contaminated worry sand is delivered to sand-washing device.Sand-washing device is made up of deaerating chamber and washed-out sand room, and sand-washing device top is provided with blast pipe and adjustable overflow weir, controls quantity of wastewater effluent by adjustable overflow weir.Sand-washing device sidewall is provided with blow-off pipe, and the top of tank body is provided with outlet pipe.
Described water-locator is severally to be dispersed towards periphery by the center of circle, perforated pipe road composition below tube wall, and the hole below tube wall can prevent the sand body blocking cloth apopore flowed downward.
Described sediment transport pipe and sand collecting chamber's outlet connection and sediment transport pipe with wash husky device inlet connection and be respectively provided with a rubber washer.
Described sand collecting chamber is funnel taper.
The air separation indoor at described sand-washing device top are provided with taper sand guide ring, the washed-out sand ring that several section is convex is equipped with in washed-out sand indoor, between washed-out sand ring, shading ring is housed, two ends, washed-out sand room are respectively provided with a lead ring, and lead ring is two the waney concentric rings connected by cross-rib, and labyrinth axle is housed between lead ring, jack-post face, labyrinth is staggered is provided with convex tooth and groove, groove is corresponding with washed-out sand ring, and convex tooth is corresponding with shading ring, forms continuous print S shape washed-out sand passage.
Described tank body is cylindrical, and bottom is turbination, and tank body lower part is provided with support.
Filtration washed-out sand flow process of the present invention comprises two parts:
1. filtration fraction: former water → water-locator filter bed (filter sand) filtration → clean water of sailing against the current → enter rises → discharges along overflow plate → outlet pipe;
2. washed-out sand part: be loaded with the filter sand of pollutant and water → through sand distributor → fall into sand collecting chamber → by carry sand pump to be promoted to along sediment transport pipe sand-washing device → deaerating chamber discharge air → clean after filter sand and water to fall → be back to filter bed along washed-out sand room continuous print S shape washed-out sand passage.
Contaminated filter sand, by carrying sand pump under the percussion of pressure-air and water, by hard hit and friction in sediment transport pipe, makes filter sand and trapped substance be peeled off.Secondly, be subject to again washing away of upstream filtered water when filter sand falls in washed-out sand room, filter sand is cleaned substantially returns filter bed, and dirt is then discharged through blow-off pipe with liter waterborne.Go round and begin again, form the flowing filter bed of an automatic cycle.
Advantage of the present invention
1 adopts the water-locator of emission type, the water distributor upwards water delivery of intaking by diffusing to surrounding from centre, can make into water evenly, treatment effect is better.
2 sediment transport pipes are in the process carrying sand, due under the percussion of pressure-air and water, dirty sand can hard hit and friction in sediment transport pipe, sediment transport pipe and sand collecting chamber export and wash husky device inlet connection and be respectively provided with a rubber washer, be mainly sediment transport pipe and sand collecting chamber lower end and wash husky device top entry and change flexible to be closely sealedly connected into by original rigid connection, the wearing and tearing of friction to equipment are clashed into, the service life of extension device to reduce.
3 due to the uncertainty of influent quality, arranges height-adjustable weir plate, by the size regulating this weir plate can change blowdown water yield in the other place connecting blow-off pipe of sand-washing device.
4 in filter process, consider sand slowly movement from top to bottom, waste water has flowed filtration from bottom to top, sand body also can bear microbe carrier effect simultaneously, in waste water and sand body contact process, considering the biomembrane covered outside sand can realize aerobic---and anoxic, possesses the organic matter in certain removal sewage and denitrification functions.
Device dirt-carrying amount of the present invention is large, good filtration effect, producing water ratio are high, relative device small investment, economize energy and human resources, simple to operate, easy maintenance.
