Description
Technical field
The utility model relates to a kind of rotary-type water decanters.
Background technique
Due to SBR(sequencing batch activated sludge) method sewage treatment process can effectively reduce construction land, for Economization on land,
Especially sewage plant is built in China Small Urban, and SBR method is relatively good selection, and main sewage treatment project is answered at present
With.The entire technical process of SBR method includes 5 stages, successively are as follows: water inlet, reaction, precipitating, draining spoil disposal and idle stage.
The equipment is mainly used for bleeding stage, it is desirable that draining is limpid, if bed mud is discharged due to negative pressure etc., if straining supply mains
Periphery leakage, which causes to strain water, to be not thorough, and is strained in pool if straining water surface dross when water and entering, to make sewage effluents water quality mark
Standard reduces.The SBR technique core equipment is XPS rotary-type water decanter, service life ratio relatively high using failure rate domestic at present
It is shorter, it strains supply mains and wall is easy to produce leak, and influence effluent quality.The supply mains that strains of rotary-type water decanter needs to pass through
The water outlet connector being fixed on the wall is in communication with the outside, and it is rotatable for straining supply mains, thus how to realize strain supply mains with
Water outlet connector on wall effectively rotate and it is water-tight be the utility model technical issues that need to address.
It is illustrated in figure 5 the rotary-type water decanter of the prior art, rotary-type water decanter includes straining water assembly, and described to strain water total
At including straining sink, with the more down-comers straining sink and connecting, the sink front end of straining sets weir crest of water decanter, takes clarification for straining
Water, down-comer for will strain the primary water taken be transported to strain water supervisor；Water supervisor is strained, is connected with down-comer, strains water for collecting
Crest of weir strains the primary water taken；Water outlet connector is fixed on pool wall, is rotatably connected with straining water and being responsible for be formed；Electric pushrod, and is strained
Water assembly is connected, and rotates for pushing to strain water assembly and strain water supervisor；Slag trap is located at weir crest of water decanter front end, floats for stopping
Slag is close to weir crest of water decanter.
When rotary-type water decanter works, slag trap 20 of the water surface dross before crest of weir carries out pushing off the slag, but effect is very
It is bad, weir crest of water decanter dross is frequently resulted in, moss etc. occurs, simultaneously because the normal fortune of water conservancy project work is strained in the influence of water surface wind
Row, it is unclean to lead to strain water, influences effluent quality.
Fig. 6 show the connection schematic diagram for straining supply mains and water outlet connector in the prior art.Outfall sewer and water outlet connector
Between use asbestos packing form, position is constantly adjusted using pressing plate and is sealed sealing, is often gone wrong as follows: 1, due to
Often adjustment sealing adjustment bolt leads to thread failure, can not adjust again；2, often adjustment causes the asbestos packing service life seriously to contract
It is short, while replacement asbestos packing is extremely difficult under water；Even if 3, sealing adjustment bolt compresses temporarily water-tight, but the equipment
Runing time is very short and starts leak, and adjustment is very frequent, causes operation amount very big；4, sewage from holddown plate it
Between leak, squeeze out water and generate jet stream, it is muddy to lead to strain pool water.Therefore there is an urgent need to Curve guide impeller, change is frequently resulted in
Water is strained in pond, exosmose fugitive water in pond, seriously affects the situation of effluent quality impact effect.
