Description

Oil-water separation device

Technical Field

The utility model relates to an environmental protection field, concretely relates to oil-water separator.

Background

At present, along with the development of production and the improvement of life, oily wastewater becomes one of the main pollutants harming the environment in the production of industrial and mining enterprises or in the life of people. The oily waste water is produced mainly from petrochemical industry, steel, coking, gas generating station, machining and other industries, and features that the waste oil is of various kinds and complex form, including mineral oil, vegetable oil, animal oil, etc. and may be further classified into floating oil, dispersed oil, emulsified oil, etc. according to form.

The drainage of industrial factory buildings comprises oil and water which are mixed together, the drainage can not be discharged, the drainage can be discharged after the high-precision technology is generally required to be processed for environmental protection, otherwise the environment can be seriously polluted, the high-precision technology can cost certain cost, the oily wastewater can be discharged after being processed, the technology for separating the oil from the water is very important, but one part of a common storage tank can be buried underground, and whether the oil is separated from the water or not can not be observed. Therefore, a floating oil-water filter device which is simple in design structure, low in maintenance cost, capable of directly observing whether oil is separated from water or not in appearance and wide in application range needs to be designed, and the defect that whether oil is separated from water or not in appearance in the prior art is overcome.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that whether the design is complicated among the prior art, the maintenance cost is high, can't observe the problem that oil and water separated at the appearance.

The utility model discloses a following technical scheme realizes:

the oil-water separation device comprises a storage tank, an inlet valve, an outlet valve, a liquid inlet pipe and a liquid outlet pipe, wherein the liquid inlet pipe and the liquid outlet pipe are respectively arranged on two sides of the storage tank, the inlet valve and the outlet valve are respectively arranged on the liquid inlet pipe and the liquid outlet pipe, the oil storage tank further comprises an oil storage tank, a bypass pipe and a communication pipe, the storage tank is connected with the oil storage tank through the communication pipe, the side wall of the storage tank is provided with the bypass pipe, the bypass pipe is made of transparent materials, an indication mark belt is arranged on the bypass pipe, and the indication mark belt is level with the bottom of the communication pipe.

Storage tank stores some liquid that are difficult for preserving usually among the prior art, so generally adopt opaque and material preparation of keeping away from the light, lead to the condition in can direct effectual observation jar, brought the inconvenience for the separation work, so need design one kind and can directly observe whether oil has already been separated with the device of water in appearance. The utility model is an improvement to the prior art.

The working process is as follows: the oil layer is led into the oil storage tank when reaching the inlet of the communicating pipe, the water level rises along with the continuous increase of water and oil in the storage tank, the bypass pipe is observed outside, when the interface of oil and water reaches the indicating mark belt on the bypass pipe, the inlet valve is closed, the outlet valve is opened at this moment, the separated water is completely discharged, and the oil and water are separated. The separation is carried out by cycling through this operation.

Compared with the prior art, this oil-water separation filter device sets up bypass pipe and is transparent material, its outside still is provided with the indicator area, density according to linker principle and oil is little, so the principle of oil on water in the volume is proportional with density in certain time quality, when the interface of water layer and oil reservoir holds with the indicator area of bypass pipe, the leading-in oil storage holding vessel of oil reservoir, the remaining water of discharge, oil-water separation finishes, the problem of whether the unable observation oil of outward appearance and water separate has been solved.

In conclusion, the device has the advantages of simple design structure, wide application range, low maintenance cost and capability of directly observing whether the oil is separated from the water in appearance.

Further, the communicating pipe is arranged at the middle upper part of the storage tank;

the communicating pipe is arranged at the middle upper part of the storage tank, so that normal oil and water discharge can be ensured.

Further, the indication mark belt is lower than the pipe bottom of the liquid inlet pipe;

the indicating mark belt is lower than the pipe bottom of the liquid inlet pipe, so that oil can be separated from water, and the oil can enter the oil storage tank through the communicating pipe.

Further, the inlet valve is arranged at the pipe orifice of the liquid inlet pipe, and the outlet valve is arranged at the pipe orifice of the liquid outlet pipe;

and after the oil and the water are separated, the oil enters the oil storage tank, and then the outlet valve is opened to discharge the water left after the oil and the water are separated.

Further, the inlet valve and the outlet valve are stop valves;

the stop valve has the advantages of small friction force between sealing surfaces in the opening and closing process, durability, small opening height, easy manufacture and convenient maintenance.

Further, the bypass pipe is in a U-shaped pipe shape;

the U-shaped pipe is designed according to the principle of a communicating vessel, so that the condition in the tank can be conveniently seen from the outside.

Further, the bypass pipe material is glass or resin;

the bypass pipe material is made of glass or resin, and the transparent medium is convenient to observe outside in the prior art.

Further, the bypass pipe is a circular pipe.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the utility model relates to an oil-water separation device, this device design simple structure, application scope is wide.

2. The utility model relates to an oil-water separation device, this device maintenance cost is few.

3. The utility model relates to an oil-water separation device, this device can whether direct observation oil has separated with the water in the outward appearance.
