Abstract
The utility model relates to an improved device of a filter pool which operates on the incoming and outgoing water from an opening. The utility model is characterized in that a syphon tube is connected with an outlet at the bottom of the filter pool and the top of the syphon tube has an aeration pipe with valve control higher than the water level needing to be kept. Compared with the prior electric control of water lever, the utility model has simple structure as only a curving syphon tube and a valve with small diameter need to be added. With very low cost, the utility model works reliably without malfunction and almost needs no assistant device. Whether the incoming flux is steady or not, water level of the filter pool can be sustained steadily at the preset water level to make sure that the filter layer always submerges in the water. And the utility model can raise the disposal efficiency of the filter pool, guarantee a water quality identical with the standard and enlarge the regeneration period and service life of the filter layer. The control device is also applicable for other water processing devices which present a demand for water level keeping.
Description
Technical field
Utility model relates to a kind of filter tank water treatment device, especially BAF or the filtration filter tank about controlling the filter tank liquid level automatically.
Background technology
On the nothing pressure is open, intake, go out down the filter tank (as BAF or filtering basin) of water running, in operational process, often because of the water pump dynamic effect, situations such as multidisciplinary water, can cause flooding quantity to change, be held, be easy to generate into water and water outlet imbalance like this and the filter tank outlet valve is flow after debugging, can cause the filter tank water level to reduce, make the filter material layer dehydration expose to the open air.The filtering layer dehydration can cause as the attached biological film mummification, and the filtrate micropore stops up, and has increased filtrate and has cleaned difficulty, and the regeneration period is shortened, and reduce work-ing life; In addition, also can cause the treating water residence time to reduce, these make that all water outlet can not stably reaching standard.For this reason, people have taked multiple measure to keeping the filter tank water level:
Chinese patent 200320109670.4 discloses a kind of water level automatic control device, by to being located at the detection of high and low water level and common electrode in the pond, and electric control circuit, electrically operated valve on the control rising pipe, thus reach the maintenance water level.Though this electrical control system can be controlled the pool inner water position, not only device is complicated, controls cost that it is higher to increase, and is higher relatively as the motorized valve cost, and water treatment device is provided with electric control gear, and poor reliability, failure rate are also high, and maintenance cost is big.
Chinese patent 200420113941.8 disclosed liquid automatic control devices, adopt built-in magnetic patch, the ball float and the alternating current contactor of through hole are arranged, the upper and lower dry-reed tube that is provided with in the liquid level control tube, the liquid level lifting, driving ball float slides up and down at the liquid level control tube, control dry-reed tube break-make, and then the control alternating current contactor is closed and disconnect control load work.This control device still is an electric control gear, still needs to detect and control two major parts, has the deficiency of above-mentioned electric control gear equally.
The utility model content
The utility model purpose is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, and cost is low, reliability height, the liquid automatic control filter tank that basic trouble free takes place.
The utility model purpose realizes that main the improvement is the siphon rising pipe that can destroy siphon in the water outlet increase by in uncovered water outlet filter tank down, and siphon destructive is in the siphon pipe curved apex ventpipe and valve to be set, thereby reaching water level descends, siphon destructive stops water outlet, keeps the filter tank water level not descend.Specifically, utility model liquid automatic control filter tank comprises water inlet, descends the uncovered filter tank of water outlet, it is characterized in that the filter tank lower outlet is connected to siphon pipe, and the siphon pipe curved apex has the valve control ventpipe that is higher than need maintenance water level.
When the filter tank was normally moved, valve was normally open on the ventpipe, wished to keep water level because the outlet of the ventpipe of siphon pipe curved apex is higher than the filter tank, full of liquid in the ventpipe, and no air, water outlet is normally discharged according to siphon, and also can not discharge from ventpipe; When for a certain reason, cause aquifer yield greater than flooding quantity, the filter tank water level descends, when being lower than the siphon pipe curved top portion, open ventpipe dehydration, air admission siphon pipe, cause siphon drainage to destroy, stop outside draining, water level no longer descends in the filter tank thereby stablized; After stopping water outlet or water inlet increase, water level raises, the water level of rising is discharged the air in the siphon pipe by uncovered ventpipe, siphon produces automatically, works better is kept in the external draining in filter tank.
When needing filter tank filtrate recoil cleaning, close valve on the ventpipe (siphon destructive valve), backwash water is entered by rising pipe, and filtering layer is carried out back flushing.Because closing of valve guaranteed that the enough pressure bounce-backs of backwash water clean.
The band that the utility model lower outlet connects can destroy the siphon pipe of siphon, both can be built-in, promptly be arranged on inside, filter tank, and also can be external, promptly be arranged on the outside, filter tank.
Siphon destructive valve, a kind of employing electrically-controlled valve that is preferably helps realizing the automated job of back flushing, because this valve is tiny, so cost is the end of than.
Because for the treatment of water has head loss by filtrate, therefore actual siphon pipe curved apex height can keep liquid level in hope, and head loss amount in decline filter tank promptly is lower than and wishes to keep elevation of water surface, and concrete the setting according to the equipment head loss determined.
The said siphon pipe of utility model, for producing the destructible curved tube of siphon and siphon, can the single pipe, also can many curved tubes; Single canal curvature portion both sides brachium can be isometric, also can be not isometric.
Utility model is owing to water inlet on uncovered, go out the filter tank of water running down, and water outlet has additional the siphon pipe that can destroy siphon, descends by the filter tank water level, make normal siphon go out water destruct, stop water outlet, do not descend thereby reach control filter tank water level, water level is kept above the siphon pipe curved apex.Utility model is owing to take the siphon pipe principle to keep water level, and existing water level is automatically controlled, has simple in structurely, only need increase the siphon pipe of a bending, and a small-bore valve, and cost is extremely low, and reliable operation, and trouble free need not increase any off-set facility substantially; No matter whether flooding velocity stable, but all in the stable maintenance filter tank in designated water level, guarantee that filtering layer is submerged in the water all the time, can improve the filter tank treatment effect, and can prolong cleaning, regeneration period and the life-span of filtering layer.This control device also can be used for other water treatment device that need keep liquid level.
Below in conjunction with two embodiments, further specify utility model.
