Abstract
The utility model relates to a novel high-speed filter tank, the bottom layer of which is a pressure equalizing empty cavity, and the upper part of the pressure equalizing empty cavity is comparted by a filter plate. A plurality of filtering heads are fixed to the filter plate, and the middle part of a filter tank is a filter bed composed of filter materials. A drainage channel, the outlet of which is connected with a drainage pipe, is hung above the filter bed. A water intake channel, the inlet of which is communicated with the raw water, is arranged at the top of the filter tank. The bottom layer of the filter tank is respectively connected with a pneumatic pipe and a water pipe. The inlet of the water intake channel, the pneumatic pipe, an outlet pipe and the drainage pipe are respectively provided with control valves which are controlled to open or close by a central control room. The utility model has a unique base layer cavity structure, saves air arranging pipelines and water arranging pipelines, enhances effective filtration area, increases water yield and has yield which is three to four times more than an ordinary filter tank.
Description
The utility model belongs to the filtering ponds that a kind of water purification is used.
When carrying out purification of water quality at present, gas distribution, water distribution gallery all will be set in general air water back washing filtering ponds, not only reduce effective filtration area greatly, influence aquifer yield, and the use of gallery also exists gas, water skewness, problem such as difficult in maintenance when circulation.
The purpose of this utility model is to provide a kind of and can improves effective filtration area, can save gas distribution, water distribution gallery again, forms the filtering ponds of uniform water distribution and air distribution system.
The bottom in filter tank of the present utility model is one and all presses cavity, separate with filter plate on cavity top, be fixed with a plurality of filters on the filter plate, the middle part in filter tank is the filter bed that is made of filtrate, above filter bed, hang a rhone, the outlet of rhone is connected with blow-off pipe, at the top, filter tank, be provided with intake chamber, the inlet of intake chamber and former water are connected, and the bottom in filter tank is connected with outlet pipe with the gas washing pipe respectively, the porch of intake chamber, gas washing pipe, outlet pipe and blow-off pipe are placed in the piping lane, and by-pass valve control all is housed respectively.
Accompanying drawing 1 is the utility model structure cross-sectional schematic.
Accompanying drawing 2 is an accompanying drawing 1A-A structure cross-sectional schematic.
Now further specify in conjunction with the accompanying drawings: as Fig. 1, Fig. 2, filter tank of the present utility model (11) is made of umbilicate cement components, its bottom (13) is one and all presses cavity, the section of cavity is done in echelon, separate with filter plate (14) on cavity top, be fixed with a plurality of filters (15) on the filter plate (14), middle part, filter tank (11) is filter bed (4), fill out at filter plate (14) by filtrate shop and to go up and to form, upper center in filter bed (4), hang a rhone (8), the outlet of rhone (8) is connected with blow-off pipe (16), (11) both sides, top in the filter tank, be provided with intake chamber (3), the former water of the inlet of intake chamber (3) and former water channel (1) lining is connected, have a plurality of inlet openings (24) on the intake chamber (3), the bottom (13) in filter tank (11) is connected with outlet pipe (18) with the gas washing pipe (17) that leads to piping lane (12) respectively, the porch of intake chamber (3), the stifled valve (2) of rubber airbag is housed, water outlet syphon hood (5) and corresponding pipe fitting (17 are installed in piping lane (12), 18,19,20) and valve (6,9,10,21), the top of water outlet syphon hood (5) links to each other with ball-cock assembly (21) by a pipe fitting (22), ball-cock assembly (21) is placed on the former water liquid level, pipe fitting (22) can join by the middle part of pipe (23) with the exhalant canal (25) of water outlet syphon hood (5), the bottom of the exhalant canal (25) of water outlet syphon hood (5) is connected with total filter back water pipe (19), the bottom of water outlet syphon hood (5) is connected with the other end of outlet pipe (18) by valve (6), and outlet pipe (18) is connected with water washing pipe (20) by valve (10), and valve (9) is housed on the gas washing pipe (17).
The utility model course of work is as follows: wait to filter former water and enter filter tank (11) by former tank (1), the stifled valve (2) of rubber airbag, intake chamber (3) and inlet opening (24) water distribution uniformity thereof, filter at filter bed (4): filter back water is under the air bag regulating action of water outlet syphon hood (5), ball-cock assembly (21), realize the permanent water level control in filter tank (11), keep above the filter bed (11) the suitable depth of water being arranged, filter bed (11) is not impacted, and filtering layer is smooth, filtration is even.Filter back water enters bottom cavity (13), by the exhalant canal (24) of flowing water Valve (6), water outlet syphon hood (5), is pooled to total filter back water pipe (19) and flows to clear-water reservoir.When filtration reaches the maximum chocking-up degree of permission or predetermined flushing cycle, promptly carry out backwash, at first open air compressor machine during flushing, with stifled valve (2) qi of chong channel ascending adversely of rubber airbag, stop into water, open draining valve (7), the upper limb that makes filter tank (11) water level reduce to rhone (8), promptly close outlet valve (6), start blower opening gas towards valve (9), air enters the bottom cavity (13) of filter bed (11), pass filter plate (14) and go up fixing filter (15), form uniform bubble, air-flow passes filter bed (11) sharply rolls filtrate, friction, shear, impurity is peeled off out from the filtering material particle surface and is floated, after 3~4 minutes, open the stifled valve (2) of rubber airbag, former water to be filtered by intake chamber (3) and inlet opening (24) ejection thereof, carried out surface sweep washing 2 minutes to filtrate again, and sewage is discharged through blow-off pipe (16); Then fetch boiling water towards valve (10), with the recoil of the press water after filter rinsing 5~6 minutes.After flushing finishes, close draining valve (7), water towards valve (10), open outlet valve (6), wash by water once more filter tank (11), reaches ordinary water level, recovers to filter.
The utility model can effectively catching and is removed in the water fine particle, impurity and adsorb it On bacterium, water is purified; The bottom cavity structure that it is unique has been saved gas distribution, cloth Waterpipe has improved effective filtration area, thereby under equal conditions, aquifer yield obtains greatly Increase, for the conventional rapid filter aquifer yield 2~3 times increase than current French V-type filter tank in vogue Add output 20~30%.
