Description

Three grades of continuous sedimentation swash plate pipe settling vessels

One, technical field:

The utility model relates to a kind of sewage disposal device, particularly settling vessel.

Two, background technology:

Sewage disposal has at present overcome the deficiency of original horizontal sedimentation tank, preferable scheme is to adopt the tube settling jar, as the disclosed tube settling jar of Chinese utility model patent CN2368585Y, as the core settling apparatus, it is big to have improved floor space to a certain extent, the energy consumption height, the problem of water treatment weak effect, but, find that in actual applications it still exists certain not enough problem, be provided with unreasonable as flow distribution plate, just consider that from prolonging the time of flow through after long-time the use, deposition is more in flow distribution plate and the tank body in addition, the precipitation ability descends gradually, so that water treatment effect instability; The artificial spoil disposal of mud discharging mouth in addition, automaticity is low, operation, maintenance cost height, energy consumption is big etc.

Three, summary of the invention:

The purpose of this utility model provides a kind of three grades of continuous sedimentation swash plate pipe settling vessels exactly for overcoming above-mentioned not enough problem, and is scientific and reasonable for structure, treatment effeciency is high, strong shock resistance, treatment effect stable, and its automaticity height, repair and maintenance are convenient in addition.

The technical scheme that the utility model is adopted for achieving the above object is as follows: a kind of three grades of continuous sedimentation swash plate pipe settling vessels, the settling vessel lower end has water inlet and mud discharging mouth, the upper end has delivery port and exhaust outlet, the bottom is the water inlet water distributing area in the settling vessel, the middle part is the decanting zone, top is the water outlet water distributing area, and the decanting zone, middle part is three grades of continuous decanting zones, and it is disposed with coarse granule settlement plate section, middle particles settling plate section and SEDIMENTATION FOR FINE PARTICLE pipeline section from bottom to top.

Top, described decanting zone is provided with the high pressure washing district, and high pressure is equipped with towards Xian's device in the high pressure washing district.

Described high pressure washing device is on the housing high-pressure water pipe to be housed, and high pressure nozzle is installed on the high-pressure water pipe.

Described settling vessel lower housing portion is that water inlet is provided with into water water distribution orifice plate, and water inlet water distribution orifice plate is the two-layer orifice plate that support connects, and upper strata orifice plate area is greater than lower floor's orifice plate, and top, high pressure washing district is the water outlet water distributing area, is provided with water outlet water distribution orifice plate.

Described water inlet water distributing area bottom is provided with independently automatic sludge discharger for heavy mud discharge area.

Described mud discharging device be one by motor-driven two-way conveyor screw, mud discharging mouth is equipped with sludge concentration monitoring device and electronic mud control valve.

The utility model adopts three grades of continuous sedimentations, sedimentation coarse granule, middle particle and fine grained successively, and sedimentation is continuous and efficient is high; Be provided with the high pressure washing device on the top of SEDIMENTATION FOR FINE PARTICLE pipeline section, connect external flushing water and can wash, remove deposition, guarantee that the sedimentation capacity of settling vessel does not descend settling vessel inside; At heavy mud discharge area automatic sludge discharger is housed, when settled sludge concentration reaches concentration of emission, then starts mud discharging device automatically and carry out spoil disposal; It is reasonable that water inlet distributing pore plate bilayer is provided with even water distribution.The utility model is for the precipitation process that contains the big sewage of high suspended matter and instantaneous change of water quality, have treatment effeciency height, effect stability, equipment and take up an area of characteristics such as few, be that the ideal that industry high suspended matter settlements of sewage such as mine, metallurgy, petrochemical industry are handled is selected its economic benefit and obvious social benefit.
