Abstract
The utility model discloses a dynamic sand filter capable of working continuously. A sewage inlet is communicated with an inflow distribution pipe at bottom of a cylinder. Under the effect of the water pressure, the inflow distribution pipe uniformly distributes the sewage, and then the sewage is reversely flowed upwards and is filtered by a sand bed. The upper section of the sand bed is a clean water area. An air-lift pump is arranged at the center of the cylinder and a cone. During the process of lifting, the suspended matter is firstly separated from the sand grain under the effect of turbulent mix, and the dirty sand after separated re-enters into a washer for further counter flow washing and goes back to the sand bed after being washed. The utility model realizes the control of the lifting speed of the dirty sand and makes the sewage inflow speed corresponded with the lifting speed of the dirty sand and the sewage with suspended matter can be treated without any other pre-treatment. The utility model is suitable for the suspended matter sewage treatment in the civil used running water, petroleum and petrochemical industry, pulp and paper industry, chemical industry, pharmacy, mining industry, foodstuff industry, power generating industry, incineration, metal surface finishing and electroplating industry, etc.
Description
Technical field
The utility model relates to a kind of water treatment facilities of continuous filtration.
Background technology
Existing sand filter is to enter into filter and dirty sand lifting device at sewage, is provided with sewage routeway such as hydroecium and water pipe; Also be provided with many pipelines at sand and separate impurities part, in addition, devices such as backwashing pump, washed-out sand water tank need be set also, structure is complicated, complex installation process, easily blockage phenomenon; Generally to pass through preliminary treatment, and the speed of uncontrollable dirty sand lifting, how many speeds that sewage enters can't be harmonious with its hoisting velocity.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of simple in structure, operation and maintenance is easy, energy consumption is low, dirty sand hoisting velocity is controlled continuous type moving sand filter is provided.
The utility model comprises the cone in cylindrical shell, the cylindrical shell, casting bed, the clear water that enters sewage mouth, cylindrical shell top go out head piece, it is characterized in that into the sewage mouth communicates with the distributing pipe that becomes a mandarin of cylindrical shell bottom, cylindrical shell and cone central authorities are provided with an airlift pump, the airlift pump top communicates with sewage sump, the sewage sump bottom communicates with the sand washer, the top, washer labyrinth of sand washer is provided with sand inlet, and bottom, washer labyrinth is provided with sand export.
Described washer labyrinth is made up of the inside and outside endless tube that is the triangle ripple.
The described distributing pipe that becomes a mandarin is provided with 6-10 transverse branch.
Be provided with the bocca of the sand grains that can evenly distribute at the casting bed middle part.
Clear water goes out head piece top and is provided with one and goes out the effluent weir that head piece communicates with clear water.
The sewage sump sidewall is provided with the draining weir that communicates with sewage draining exit.
The utility model need not be provided with backwashing pump, the washed-out sand water tank in the existing sand filter, simple and ingenious structure, and operation, easy maintenance, energy consumption is low, and the loss of flood peak is few; Realized that dirty sand hoisting velocity is controlled, how many speeds that makes sewage enter can be harmonious with the hoisting velocity of dirty sand; Need not preliminary treatment and can handle the sewage that contains suspension.Contain the processing of suspension sewage applicable to industry such as civilian running water, Petroleum and Petrochemical Industry, pulp and paper industry, chemical industry, pharmacy, mining, food, generating, burning, metal finishing, plating.
Description of drawings
Accompanying drawing is the utility model inner structure cut-away view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment:
With reference to accompanying drawing:
Present embodiment comprises the cone 5 in cylindrical shell 1, the cylindrical shell, the clear water on casting bed 3, cylindrical shell top goes out head piece 4, the water inlet 7 of cylinder body outer wall communicates with the distributing pipe 2 that becomes a mandarin of cylindrical shell bottom, cylindrical shell and cone central authorities are provided with an airlift pump 15, the airlift pump top communicates with sewage sump 6, the sewage sump bottom communicates with the cleaning labyrinth of sand washer, cleans top, labyrinth and is provided with sand inlet 8, and bottom, washer labyrinth is provided with sand export 17.
The sewage that enters from the water inlet 7 of cylindrical shell 1 outer wall during use is introduced into the distributing pipe 2 that becomes a mandarin of cylindrical shell bottom, the distributing pipe that becomes a mandarin becomes 6-10 transverse branch, under the effect of hydraulic pressure, sewage is evenly distributed the distributing pipe that becomes a mandarin and upruss filters through casting bed 3, casting bed top is the clear water zone, and water purification goes out head piece 4 through clear water again after by effluent weir 14 and flows out.
The filter sand that contains impurity from 5 bottoms of the cone in the cylindrical shell by the sewage sump 6 of airlift pump 15 pumps to the top, in the process that promotes, under the turbulent mixture effect of mutual collision and water slug between the sand grains, suspension is separated from sand grains for the first time, dirty sand after the separation enters the cleaning labyrinth 9 of washer again by sand inlet 8 from the sewage sump lower end, cleaning the labyrinth is by interior, the endless tube that is the triangle ripple is outward formed, clean by the further back flushing of clear water zone low discharge clear water after filtering, impurity sewage draining exit 10 is discharged, the sewage that lifting process produces is also discharged by sewage draining exit 10 by the draining weir 13 of sewage sump sidewall again, and the heavier casting bed that returns of sand particle after cleaning, bocca 16 by the casting bed middle part is evenly distributed sand grains in casting bed, casting bed is constantly done slow sinking campaign in equipment.Pump is provided by air compressor by the air duct in the middle of the airlift pump 11 with compressed air, by the control valve control flow and the pressure that are installed on the panel 12.
Claims (6)
