Introduction of the development process:
in order to solve the problem of oil slick in the waste water discharge chamber or waste water lifting chamber in the technical background, adopt the oil slick collector, the existing liquid level oil slick collecting technology, belong to petrochemical industry, smelting, collection of river and sea lake surface debris, suitable for the collection of mineral grease or collection of debris and rubbish floating on the water surface; the water surface floating grease in the restaurant wastewater is mostly a mixture of animal and plant edible grease and tiny food residues, has the characteristics of easy decomposition and caking and easy adhesion, and is not suitable for the existing liquid surface floating oil collecting technology.
For example, the water temperature in the wastewater collection box is required to be not less than 20 ℃ in a collection mode of combining the turntable and the crawler belt with the scraping plate, an electric heating device is required to be additionally arranged, and the energy consumption is increased; for example, a gear oil pump is adopted, and oil pump faults are caused by tiny residues in grease or condensed grease; for example, in patent application publication CN202220584753.1, a fish pond float collection device is disclosed, wherein a float collector floats on the surface of a fish pond, a submersible pump is installed at the bottom of the fish pond, and the float collector is connected with the submersible pump through a hose; the buoy of the floating collector is fixed on the peripheral wall of the top of the shell at equal angles, the siphon disc is arranged on the top of the shell, the filter screen is erected in the shell, a gap is reserved between the filter screen and the peripheral wall of the shell, and a pipe joint is arranged at the bottom of the shell and connected with a hose. In this patent, the floating collector is directly connected to the submersible pump and is used in a water body suitable for a large water surface, such as a pond, a fish pond, etc., but is not suitable for a water tank with a small volume, water in a connecting hose is directly discharged by the water pump after the water pump is started, the buoyancy of the floating collector is increased, the water surface is floated, and the water pump cannot pump water to form a gas (air lock) phenomenon.
In the research and development, a solution 1 is designed firstly, a container for collecting floating oil is arranged in a water collecting tank, a submersible pump is arranged in the container for extracting oil-containing fat wastewater, and the submersible pump pumps the oil and water entering the container out of the container. When the liquid level of the water collecting tank 1 is higher than that of the container, the floating oil can flow into the container after the water exceeding the container is completely discharged during the operation of the oil pump, and is discharged through the oil pumping pump, so that the problem of low working efficiency is also caused; the water level measuring device is added into the water collecting tank 1 to control the start of the oil pumping pump in the container, when the liquid level of the water collecting tank 1 is slightly higher than that of the container, the water pump is started to enable the floating oil on the liquid level to enter the container, the defect is that the opening of the container is slightly larger, the water quantity flowing into the container is larger than the water discharge quantity of the water pump, the oil pumping pump can only discharge the wastewater entering the container during operation, the floating oil still floats on the liquid level in the container, and the design requirement of discharging the floating oil and the wastewater together can not be met.
On the basis, the utility model further improves the water inlet of the container, enlarges the area of the inflow opening of the container, ensures that the contact surface of the floating oil on the liquid surface of the water collection tank 1 flowing into the water outlet of the container is larger, improves the instant inflow amount of the floating oil, reduces the flow cross section of the connecting channel between the water inlet of the container and the cavity of the container, ensures that the floating oil and the wastewater fall into the container are more concentrated, and ensures that the floating oil in the container is easier to be discharged by the oil pump under the disturbance of the water flow. It can be seen that the obtaining of the limiting parameters of the present application is not obvious and is not a conventional technical means easily imaginable to a person skilled in the art.
