Description

Rotary-type water decanter

Technical field

The utility model relates to field of sewage treatment equipment, especially a kind of rotary-type water decanter.

Background technique

Water decanter is also known as decanter, is one of the mechanical equipment of most critical in SBR technique.Hydrocone type can be divided into and strain water Device, rotation water decanter, self-floating water decanter, mechanical water decanter, widely used at home at present is mostly rotary.Water decanter It is the equipment for the regular exclusion primary water that SBR technique uses, it has and can drain primary water from static pool surface, without stirring Dynamic precipitating, it is ensured that the effect of effluent quality.Rotary-type water decanter is more generally used in China, this kind of water decanter is by machinery Water vertical tube is strained in push rod promotion, drives decanting weir tank decline, water is discharged outside pond.It the advantage is that and be discharged using weir flow, water outlet It is more uniform.But due to by pond too much influence, water decanter pulling force suffered by branch pipe and pressure is larger causes in the process of running Lateral bending keep complete machine structure unstable, and the generally outdoor construction of pond body, just there is one in its pond body during straining water for this A little impurity enter pipeline and are not easy to be discharged, and accumulation for a long time, which will lead to blocking and generate dirty gas, causes draining to be obstructed, and influence making for complete machine Use the service life.

Utility model content

To solve the above-mentioned problems, the utility model provides a kind of rotary-type water decanter, adds in branch drain two sides Stiffening plate is fixed, and is provided with snorkel connection main sewer and is strained mill weir for managing the discharge of interior gas.It can be automatic when straining water The impurity in drainage is crossed, will not block pipeline influences complete machine service life.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of rotary-type water decanter, which is characterized in that including supervisor's support base, handspike bearing, electric pushrod device, draining Supervisor, strains mill weir, snorkel at branch drain；Supervisor's support base is connect with the drain header；Between on the drain header Every being provided with a plurality of branch drain；The branch drain two sides are fixed by stiffening plate；The other end of the branch drain It is connect with the mill weir of straining；The electric pushrod device is mounted on above pond body on the handspike bearing, pushes complete machine movement；Institute It states snorkel connection main sewer and strains mill weir.

The drain header is that both ends lead to structure.

The drain header is connected by rotary joint with the end of the branch drain, for leading for liquid in pipe It is logical.

Described strain is equipped with floating drum on front side of mill weir, the depth for straining water at water layer is adjusted during straining water.

The floating drum outer surface is equipped with skimming layer, and the skimming layer uses stainless steel cloth, and is fixed by clasp.

The branch drain is by drain header described in flanged joint and described strains mill weir.

The branch drain port is provided with slag trap, the slag trap rectangular plate.

The slag trap is detachable structure.

The snorkel connects main sewer and strains mill weir.

The electric pushrod device includes electric pushrod, connecting rod and motor, and the electric pushrod and the connecting rod connect It connects, is moved accordingly under the running of the motor.

The utility model has the beneficial effects that solving traditional water decanter pulling force and pressure suffered by branch pipe in the process of running The problems such as lateral bending caused by larger keeps complete machine structure unstable and impurities in water filters clean caused inner pipeline plug plug.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

In Fig. 1, drain header 5 is mounted on supervisor's support base 1 and is installed along in pond, and electric pushrod device 13 is pacified On handspike bearing 2 above pond, electric pushrod device 13 includes electric pushrod 3, connects 4 bars and motor 14, electronic to push away Bar 3 connect cooperation with connecting rod 4.When motor 15 operates, electric pushrod 3 and connecting rod 4 move repeatedly, drive drain header 5 lower supervisor's 1 centers of rotation of support base are made convolution and are swung.

Preferably, drain header is designed as the logical structure in both ends, reduces the diameter of drain header, and double drainage increases draining Amount.

In Fig. 2, drain header 5 is connect by rotary sealing seat with supervisor's support base 1, carries out revolution cooperation.Draining master A plurality of branch drain 6 is arranged at intervals on pipe 5, the other end of branch drain 6 is connect with mill weir 7 is strained, and strains the front end setting of mill weir 7 There is floating drum 9 and 9 outer surface of floating drum is equipped with skimming layer 10, skimming layer 10 uses stainless steel cloth, and is fixed by clasp.Draining branch 6 two sides of pipe are equipped with stiffening plate 11, and for fixing the structure of branch drain 6, branch drain 6 connects drain header 5 by flange 15 With strain mill weir 7.Snorkel 8 connects drain header 5 and strains mill weir 7, for the gas in discharge tube.

In above structure, 6 two sides of branch drain be equipped with stiffening plate 11, avoid pulling force suffered by branch pipe in the process of running and Lateral bending caused by pressure is larger keeps complete machine structure unstable.

Preferably, snorkel 8 connects drain header 5 and strains mill weir 7, and the generally outdoor construction of pond body, this is just straining water mistake Enter pipeline there is some impurity in Cheng Zhongqi pond body to be not easy to be discharged, accumulation for a long time, which will lead to blocking and generate air pressure, causes row Water is obstructed, and skimming is timely exhausted and extends complete machine service life.

Preferably, branch drain 6 connects drain header 5 by flange 15 and strains mill weir 7, convenient for disassembly and assembly.

Rotary-type water decanter work when, water decanter floating drum 9 keeps and strains at any time mill weir 7 and be in same plane, aeration with Precipitate phase strains mill weir and is located at the water surface or more, mill weir 7 is strained when straining water drops to the water surface or less by control system and drained.It is floating The skimming layer 10 of 9 periphery of cylinder has blocked the residue of upper layer clear water, guarantees effluent characteristics.When water level decreasing is strained to lowest water level completion After water, water decanter returns quickly to original state.It is laminar state into the water flow for straining mill weir during straining water, water decanter Decrease speed is used water quantity holding and is stablized, and skimming layer 10 plays skimming during straining water.

Preferably, slag trap 12 is arranged in branch drain 6 and connects at the port for straining mill weir 7, as the variation of water level is discharged The phenomenon that amount will increase or water level is lower, and water outlet is caused to run mud strains mill weir 7 and flows into a large amount of silt impurity, and water quality is strained in influence, Effluent characteristics decline or the blocking of pipeline are caused, needs that conduit component is cleared up and repaired in time, expends a large amount of manpower Material resources.Slag trap 12 is arranged in branch drain 6 and connects at the port for straining mill weir 7, and secondary pushing off the slag, most of mud are carried out when straining water Sand can be left, and guarantee effluent characteristics.
