Detailed Description

The invention is further described with reference to the following specific drawings and examples.

The utility model discloses combined neotype water hinder oily material to the effect of kinetic energy when combining liquid flow, when realizing water oil separating, the pollution on membrane material surface obtains certain control. Wherein the housing 1 serves as a structural platform for the entire device, on which other accessories are built. Wherein the oil-water mixture storage tank 2 is fixed on the bracket 3 and is used for storing oil-water mixture to be treated. The tank is also connected to an air pump 5 via an air pipe 4 for stabilizing the pressure in the tank 2. The top end of the storage tank 2 is provided with a barometer 6 which can display the pressure value in the tank body. In addition, the oil-water mixture storage tank 2 also comprises a liquid inlet 7, a drain port 8 and a liquid outlet 9, and the three ports are controlled by electric valves. Wherein inlet 7 and evacuation mouth 8 link to each other with shell box 1, and liquid outlet 9 is inside the box, and is linking to the swash plate support 10, can make liquid in the storage tank can flow to the swash plate support from the liquid outlet like this. A flow control meter 11 is also provided at the outlet 9 to set the flow rate of the fluid flowing out of the outlet. Since the pressure inside the tank changes as the liquid level in the storage tank decreases, the flow rate can be stabilized by controlling the pressure inside the tank 2 to be stable. The air pressure can be in a stable range through a set value of the pressure gauge, so that the air pump 5 can be controlled to realize the purpose, when the pressure exceeds a set threshold value, the air pump 3 stops pressurizing, and when the pressure in the tank body is reduced to a set minimum value, the tank starts to work, so that the stability of the pressure in the tank 2 is realized, and the relative stability of the flow rate of liquid in the inclined plate support is ensured. The inclined plate bracket 10 is made of a mesh plate, and the upper surface of the inclined plate bracket is covered by a water-passing oil-blocking material 12. When the oil-water mixture flows over the inclined plate bracket covered with the water-passing oil-blocking material, water flows out of the water-passing oil-blocking material and flows into the water storage tank 13 through meshes in the inclined plate bracket, and a drain port 14 of the water storage tank 13 is connected with the box body shell and used for draining the water in the water storage tank. The mixed liquid continues to flow along the inclined plate bracket, only the oil is left in the last inclined plate bracket, and the mixed liquid flows into the oil storage pool 15 under the action of gravity, so that the oil-water separation is completed. The drain 16 of the reservoir 15 is connected to the housing shell. The electromagnetic valves of the liquid outlet 9, the oil-water mixture storage tank 2 are controlled by air pressure inside the oil-water mixture storage tank, the evacuation port 8 and the liquid outlet 9, and the operation is realized by the electric control system 17, so that the operation of the whole system can be automated, and a large amount of labor cost is saved. The box shell can be opened, and the inside maintenance of box can be realized.

In the process, the oil-water mixture is in a flowing state, impurities staying on the surface of the water-passing oil-blocking material can be flushed away along with liquid flow, and meanwhile, the flow meter can be adjusted to control the flow rate to further flush the impurities on the surface of the material, so that the self-cleaning of the surface of the water-passing oil-blocking material is realized. After the equipment is used, the surface of the membrane material is cleaned by a small amount of clear water.

The method comprises the following steps:

1, after the equipment is placed at a treatment position, an oil-water mixture to be treated is pumped into an oil-water mixture storage tank 2 through a liquid inlet 7;

2, opening a valve of the liquid outlet 9 through an electric control system 17, discharging the oil-water mixture in the storage tank into the inclined plate bracket 10 through a pipeline, and allowing the mixed liquid to flow downwards along the inclined plate bracket;

3, the air pressure range of the oil-water mixture storage tank 2 of the flow meter 11 of the liquid outlet 9 is adjusted through an electric control system, and when the mixed liquid flows to the lowest end of the inclined plate bracket 10, no water drops from meshes of the inclined plate bracket when the mixed liquid is observed from an observation window in the tank body, so that the water in the mixed liquid is ensured to be separated before the mixed liquid flows to the oil storage pool 15; meanwhile, the liquid output in the flowmeter 11 cannot be too small, so that impurities adhered to the surface of the material can be washed away;

4 when the value displayed by the flowmeter is continuously lower than the set value, the electric control system 17 starts to alarm to indicate that the liquid level of the liquid in the storage tank 2 has dropped to the liquid outlet, which can be divided into the end of separation and the end of the separation process;

5, continuously repeating the steps 1 to 4 until all the treated oil-water mixture is treated;

and 6, adding a small amount of clean water from the liquid inlet to clean the surface of the water and oil blocking material 9 above the water storage tank, and naturally drying for later use.

In a word, the utility model discloses degree of automation is high, and is nimble to dismantle, and the automatically cleaning on material surface then utilizes the kinetic energy of rivers itself to realize. Therefore, the service life of the material is greatly prolonged while the same separation effect is ensured, and the maintenance times and cost of personnel are reduced.

The above description is only one of the embodiments of the present invention, and it should be understood by those skilled in the art that a plurality of improvements and optimizations may be made without departing from the concept of the present invention, and these improvements and optimizations should also be considered as within the scope of the present invention.
