Abstract

The utility model relates to a sewage recycling and pretreatment device that can effectively separate solid precipitations in sewage such as oil and sands without adding any chemical drug and can be conveniently constructed, used and cleaned. The utility model consists of a main tank body, spherical taper shaped coagulating devices, a water inlet pipe, a ring water collecting pipe, a water outlet pipe, an oil collecting funnel, an oil absorption device, an ozone input device, a sewage discharge outlet, a top cover and a bracket, etc. A group of spherical taper shaped coagulating devices are installed in parallel in the middle part of the main tank body, and divide the tank body into a clarification cavity and a precipitation cavity; after entering the precipitation cavity in the lower part, the sewage rises along a taper shaped slope and overflows into the clarification cavity on the upper part, and the solid precipitations are precipitated and gathered at the bottom of the precipitation cavity, while the oil agglomerates and floats on the water surface in the clarification cavity. The bottom of the precipitation cavity is provided with the sewage discharge outlet, and the clarification cavity is provided with the oil collecting funnel and the ozone input device.

Description

The reusing sewage pretreatment unit

Affiliated technical field

The utility model relates to a kind of device of sewage disposal, is that solid sediment sewage such as a kind of oil-containing and sand reclaim pretreatment unit, be particularly suitable for the washing bay and in application in the cyclic utilization system of water.

Background technology

At present, known carwash and the middle most structure more complicated of water reuse apparatus, wherein oil, sand, water sepn are not generally finished in same unit, need dig mostly and establish underground settling tank.With this class device, instrument is not installed, is used and clears up all not too conveniently, and has increased engineering cost and use cost, also is easy to generate foul smell and peculiar smell.

Summary of the invention

In order to overcome the deficiency of pre existing treatment unit in carwash and intermediate water reuse system, the utility model provides a kind of pretreatment unit that is specifically designed to oil-containing, husky reusing sewage, this device oil, husky, water sepn efficient height, engineering and use cost are low, install, use, clean all very convenient.And be provided with ozonizer, effectively remove stink and peculiar smell in the water.

The technical scheme that its technical problem that solves the utility model adopts is: this device helps condenser, water inlet pipe, annular header, rising pipe, water-in, oil-collecting funnel, ozone input unit, sewage draining exit, top cover, support, oil header etc. to form by main tank body, circular cone.

One group of circular cone helps the parallel order of condenser to be installed in main jar intravital middle part, tank body is divided into clarification chamber and precipitates chamber two cavitys up and down.The top of each cone-shaped body is provided with spillway, and water inlet pipe passes the cone-shaped body top and enters in the precipitation chamber.The annular header is located at the clarification chamber bottom, and has one group of little suction hole.Annular header two ends link to each other with rising pipe.The oil-collecting funnel is positioned at the horizontal plane place, and connects an oil header, and the oil absorbent material material is housed in the oil header.The ozone input unit is arranged in the clarification chamber.

Main tank base is a doline, is used to collect solid sediment; There are a sewage draining exit and wash water valve in its lower end, conveniently solid sediment is discharged.

The utility model in use, sewage enters the precipitation chamber by water-in, and helps through one group of circular cone and rise on the cone inclined-plane of condenser and overflow is advanced in the clarification chamber.Help in circular cone under the effect on condenser inclined-plane, force water flow inside to keep well stability, make precipitation of solid material such as sand in the water in the doline cavity of bottom; And oil content is agglomerated together under the effect of tapered slope, float at the clarification chamber water surface, and the oil-collecting funnel by the horizontal plane place, import in the oil header.Clear water after the processing sucks by the aperture on the annular header of clarification chamber bottom, exports through rising pipe.

The beneficial effects of the utility model are, as the sewage pretreatment unit, can easily separation such as the oil content in the sewage, solid sediment be come out, and the efficient height need not to add any chemicals; Construct, use, clean all very convenient.And can remove stink or other peculiar smell in anhydrating.
