Abstract
The utility model relates to a float type novel decanter, which is a drainage apparatus for the supernatant fluid in a decanting reaction tank of a sewage treatment plant adopting the sequencing batch reactor (SBR) and variant techniques thereof to treat sewage. The decanter comprises a float (1), a guide rod (2), a draining pump (3), a delivery hose (4), a float-lifting slider (5), a limiter (6), a suction port (7), an electric control system (8) and the like. The decanter is arranged in the sewage treatment reaction tank and can be moved up and down along with the water level, the drain tube is a hose, and the inlet of the decanter is enclosed by the baffle type float in order to block scum from flowing in.
Description
Technical field
The utility model provides a kind of water-freeing arrangement that is used for sewage work's reaction tank, belongs to sewage treatment area.
Background technology
At present with sequencing batch active sludge (SBR) and deformation technique thereof, as Continuous Flow intermittent aeration method (DAT-IAT), CASS is that the sewage work of main process all needs to adopt and strains the hydrophone draining with these.Along with country more and more payes attention to environmental protection work, some small sewage treatment plants do not have matched water-freeing arrangement when adopting these art breading waste water.If when adopting relatively large sewage work rotary-type water decanter commonly used and the draining of siphonic decant device, investment cost height not only, the control mode difficulty is installed complicatedly, and is not very to coordinate with a whole set of technology.So my company in conjunction with engineering experience, in conjunction with weir gate formula, telescopic advantage of straining hydrophone, develops a kind of equipment that is widely used in based on the small sewage treatment plant reaction tank draining of SBR technology.
The utility model content
The utility model provides a kind of simple installation, low, the stable a kind of device that is used for the reaction tank draining of investment at above situation.Its technical scheme is:
A kind of device that is used for sewage work's sbr reactor pond draining includes floating drum (1), guide rod (2), wet-pit (3), delivery hose (4), buoy lifting slide block (5), stop means (6), water sucking mouth (7), electric control system compositions such as (8); When the sbr reactor pond needed draining, Controlling System offered power signal of wet-pit, and wet-pit starts starts working.In the side of floating drum, can be according to the size of buoyancy and the size of water displacement, water discharge time is determined the position and the caliber size of water sucking mouth.Along with wet-pit is constantly extracted water in the floating drum out, the outside supernatant liquor of floating drum constantly enters the floating drum from suction port, and the extraneous water surface also constantly descends.When water level dropped to minimum discharge level, tank level control system can offer signal of general control system, cut off the power supply of wet-pit, quit work, and the water sucking mouth can be sealed simultaneously.Along with the beginning of next work period, constantly water inlet in the sbr reactor pond, floating drum is strained hydrophone and can be risen along guide rod, until the highest discharge level owing to the buoyancy of water effect.According to technological design, enter the next work period after for some time more then.
The utility model compared with prior art has following advantage:
1. the height of drainage pipeline, direction can arbitrarily be adjusted according to the situation at scene: because sbr reactor pond and deformation technique reaction tank thereof generally are to build in undergroundly or semi-underground, require during draining that the water level in waterways is very low just can satisfy the demand.And this pontoon type decanting device can drain into water more than the ground.And bellows can be adjusted the direction of draining.
2. simple installation: the built-in fitting that this pontoon type decanting device only needs to reserve guide rod when civil engineering get final product.
3. it is effective to strain water: owing to the time adopted unique water-in sealing measure in design, when straining hydrophone and quit work, the water sucking mouth is closed, and sewage enters floating drum inside when having prevented aeration.
4. less investment: because needed material itself is less, and can satisfy the needs of straining water, the cost of equipment own is lower.
5. applied widely: small-sized now (treatment capacity is at 10-400m
3/ d) in the Industrial Wastewater Treatment, SBR technology since the treatment effect of its efficient stable be widely adopted.
Description of drawings
Fig. 1 is the novel water heater structure synoptic diagram of straining of a kind of Float cylinder type of the utility model, and floating drum (1), guide rod (2), wet-pit (3), delivery hose (4), buoy lifting slide block (5), stop means (6), water sucking mouth (7), electric control system (8) top water-level (9) lowest water level (10) are arranged.
Embodiment
According to the novel water heater structure synoptic diagram of straining of a kind of Float cylinder type of Fig. 1, the utility model has floating drum (1), guide rod (2), wet-pit (3), delivery hose (4), buoy lifting slide block (5), stop means (6), water sucking mouth (7), electric control system compositions such as (8).Electric control system (8) is connected with wet-pit (3), wet-pit (3) and delivery hose (4), water sucking mouth (7) is connected with floating drum (1), and there are guide rod (2) and buoy lifting slide block (5) in floating drum (1) outside, and water sucking mouth (7) are connected with stop means (6).According to whole technological design, when the needs draining, Controlling System is transferred to signal of wet-pit, and wet-pit starts, and discharges by flexible hose, and the rising pipe direction can arbitrarily be adjusted.Elevation of water surface is constant constantly in the floating drum, and the water of floating drum outside enters floating drum inside by the water sucking mouth, and extraneous water level constantly reduces, and floating drum also decreases, thereby reaches the purpose of stablizing draining.When water level arrives minimum discharge level (10), stop means meeting transmission signal, deenergization stops to strain water.Finish one and strain the water cycle.
Claims (1)
- The novel hydrophone of straining of a kind of Float cylinder type is characterized in that including floating drum (1), guide rod (2), wet-pit (3), delivery hose (4), buoy lifting slide block (5), stop means (6), water sucking mouth (7), electric control system compositions such as (8); Electric control system (8) is connected with wet-pit (3), wet-pit (3) has delivery hose (4), water sucking mouth (7) is connected with floating drum (1), and there are guide rod (2) and buoy lifting slide block (5) in floating drum (1) outside, and water sucking mouth (7) are connected with stop means (6).
