Description

Accurate filter

Technical field

The utility model belongs to water purification and retrieving arrangement, refers in particular to a kind of Collecting flocculation, sedimentation, filters the accurate filter in one.

Background technology

Chinese patent application 99240225.5 discloses a kind of " integrated sedimentation suspends and filters purifier ", the bottom of device is flocculating chamber's air chamber of holding concurrently, the centre is the negative area, the top of negative area is the lightweight suspension filter material layer, filtrate is the lightweight suspension particle, density is littler than filter liquide, and the top of filtrate is grid or filter cap, and grid top is clear water zone.The deficiency that exists is: 1, and mud discharging mouth is arranged on the planar bottom surface of housing, and the mud that gets off in the negative area does not have fine collection mud device, and difficult deposition is got off, and easy and coagulation water is mingled with; 2, water outlet is arranged on a side of clear water zone, and the short circuit and the bias current phenomenon of current appears in meeting in service, wasted filtration area, influenced filtration efficiency; 3, the valve on the water inlet pipe and water outlet pipe is depended in the turnover of the water yield fully in the equipment, and device interior does not have the stable control of the water yield, easily influences flocculation, sedimentation and filtering net effect during operation; 4, the equipment upper end closed, after operation for some time, grid or filter cap are difficult to maintenance and change.

Summary of the invention

The utility model is just in order to overcome above-mentioned deficiency, provide a kind of and collected that mud is effective, water outlet does not have short circuit or bias current, accurate filter that overall treatment efficiency is high, main innovation is at housing bottom one taper sludge hopper to be set, taper sludge hopper top is equipped with a flanged cap, and the taper sludge hopper port of flanged cap both sides leaves the muddy water inlet; In clear water zone, set up an annular water distributor, the short circuit of current and bias current in the resistance; Taper sludge hopper flanged cap is provided with a return line in the space, with the intravital current of constant shell, guarantees the bulk treatment effect; The housing top is uncovered, but change filter cap makes in the operational process and can change the filter cap easily for the outer spiral shell of installing goes out structure.Specifically implement like this: accurate filter, comprise that housing, housing are made of mud collection area, flocculation zone, negative area, filtrating area, the connection of clear water zone water from bottom to up successively, it is characterized in that mud collection area is a taper sludge hopper, taper sludge hopper top is equipped with a flanged cap, the taper sludge hopper port of described flanged cap both sides leaves the muddy water inlet that is communicated with flocculation zone, and the flanged cap top drilling is communicated with an inlet pipe; Feed liquor jar top, one center connects water inlet pipe, and the top connects vapor pipe, and the bottom is fixed on flanged cap central authorities, has posticum on the sidewall of itself and flanged cap junction.Waste water is after water inlet pipe enters center feed liquor jar, confection within it, enter flocculation zone through the bottom side wall outlet, because of being filled with pressure air in the sludge hopper, current enter the negative area, top under pressure promotes, under the effect of inclined tube or swash plate, macrobead settles down, the muddy water that comes together in sludge hopper port both sides along flanged cap enters the mouth, and enters in the taper sludge hopper, and the current that come through the negative area enter and enter the clear water zone discharge after filtrating area filters.Adopt the anti-purging method of the regular disturbance of air during backwash,, make the current flushing filtrate in the clear water zone by bleeding, downwards through the negative area, flocculation zone, enter mud collection area and discharge, do not have the blockage problem that produces because of the medium bonding.

Adopt the suspension filtration medium in the utility model filtrating area, utilize the absorption of suspended particles layer and filteration to carry out solid-liquid separation, remove the suspended matter in the water, filtrate is the best with polymer inert plastic ball, and it is corrosion-resistant, good filtration effect, long service life.

Clear water zone of the present utility model is built-in with an annular water distributor, evenly has gully-hole on it, thereby evenly catchments in the clear water zone zone, has effectively stoped the short circuit and the bias current phenomenon of current, has made full use of effective filtration area.

Case top of the present utility model is uncovered, and its easier outlet system to equipment is checked, detected and keeps in repair; Make the circular cone grating filter cap body that connects the filter cap of clear water zone and filtrating area into the long tube of grating cylinder type, also be equipped with stiffening web on the filter cap body, promptly filter cap by the filter bar on the filter cap body of bottom, top, nut be installed constituted, filter cap body is the long tube of grating cylinder type, filter cap body becomes whole syndeton with outside screw filter bar, filter cap body diameter is slightly less than the filter shank diameter, nut sleeve is installed to be connected on the outside screw filter bar, nut is installed is made up of two nuts and union lever thereof up and down, union lever is built-in with outside screw and filters the internal thread that bar connects.Filter is after cap is installed on the division board, if when needing dismounting and change filter cap, as long as from outward winding filter bar and extract the filter bar out of housing open-mouth, the long tube cylinder type body of bottom also is drawn out of simultaneously, need not to go below division board to change again, install change very convenient.

The utility model is provided with a return line in taper sludge hopper flanged cap space, with the intravital current of constant shell, guarantee the bulk treatment effect.

Housing and each parts adopt the glass reinforced plastic material, and acid-fast alkali-proof is anti-oxidant, and do not need every year to carry out anticorrosion maintenance more than 10 years integrally-built normal work-ing life, can be used for the recovery of the suspended matter in the corrosive mediums such as spent acid and salkali waste.

The utility model is equipped with regular plasma discharge system in taper sludge hopper bottom, make the operation of strainer not be subjected to artificial factor.

The utility model is a kind of collection sedimentation, filter, plasma discharge, integrated multifunctional equipment for separating liquid from solid such as cleaning, collection mud in service is good, water outlet is steady, the filter clogging effect height, life-span is long, continuous operation time is long, invest little, treatment effect is good, working cost is low, the also continuous low pressure operation of cocoa, the regular discharge concentrated solution, operational administrative is very convenient, be applicable to the waste water filtering reuse, the spent acid filtering and concentrating, solids recovery etc., be specially adapted to the occasion that unsuitable sedimentary ultrafine powder reclaims, as the recovery of Ti02 in dense spent acid of titanium powder industry and acidity (neutrality) waste water, paper waste is handled, the mine, the cinder wastewater treatment, former water treatment etc.
