Description

Technical Field

[0001] The utility model relates to the technical field of hydropower stations, and in particular to an oil-water separation device for a water collection well of a hydropower station. Background Art

[0002] A hydropower station is composed of a hydraulic system, a mechanical system, and an electric energy generating device. It is a key water conservancy project that realizes the conversion of water energy into electric energy. The sustainability of electric energy production requires that the use of water energy in the hydropower station be uninterrupted. The water sources stored in existing hydropower stations are inevitably mixed with some discharged garbage or catering waste. The impurities and grease remaining in these garbage will inevitably affect the quality of the water source, which requires the use of an oil-water separation device in the hydropower station's water collection well.

[0003] Patent document CN206255872U discloses an oil-water separation device for a water collection well of a hydropower station, "including an inclined box body and a vertical shaft connected to the inclined box body, a water outlet is provided at the bottom of the vertical shaft, the oil-water separation device also includes a high-temperature steam generator, an air duct is provided in the inclined box body, the air duct is provided with a plurality of air vents, and the high-temperature steam generator is connected to the air duct. The technical solution of the utility model can improve the oil-water separation efficiency and reduce the oil-water separation cost".

[0004] The above-mentioned equipment heats the oil-water mixture through a high-temperature steam generator, and the water in the oil-water mixture evaporates, thereby separating the water from the oil-water mixture. However, separation by evaporation requires waiting until the water reaches the temperature required for evaporation. The separation takes a long time and has low efficiency, which requires staff to improve the equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the low efficiency of the separation method of an oil-water separation device for a water collection well of a hydropower station in the prior art, thereby providing an oil-water separation device for a water collection well of a hydropower station.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A box body, a first collecting box is overlapped at the bottom of the inner wall of the box body, slots are opened on both sides of the top of the first collecting box, a second collecting box is overlapped on both sides of the bottom of the box body, and one side of the second collecting box is overlapped with both sides of the first collecting box, a first protective box is arranged at the bottom of one side of the box body, a first servo motor is arranged on the inner wall of the first protective box, a threaded rod is arranged at the output end of the first servo motor, and a scraper is threadedly connected to the surface of the threaded rod.

[0009] As an optional technical solution, a connecting pipe is provided at the bottom of one side of the box body, and a connecting groove is provided on the inner wall of the box body.

[0010] As an optional technical solution, a second protection box is arranged on the top of one side of the box body, and a second servo motor is arranged on the inner wall of the second protection box.

[0011] As an optional technical solution, a first gear is provided at the output end of the second servo motor, and a second gear is meshingly connected to the surface of the first gear.

[0012] As an optional technical solution, the inner wall of the second gear is provided with a mounting cylinder, the inner wall of the mounting cylinder is provided with a screen, and both ends of the mounting cylinder are rotatably connected to the inner wall of the box body.

[0013] As an optional technical solution, a connection block is provided on the top of one side of the box body, and a feed pipe is provided on the inner wall of the connection block.

[0014] As an optional technical solution, an oil-water mixing box is overlapped on one side of the inner wall of the box, a garbage bin is overlapped on the other side of the inner wall of the box, and a guide tube is arranged on the top of the inner wall of the box.

[0015] As an optional technical solution, a discharge port is provided on one side of the oil-water mixing box, and a transport trough is provided in the middle of the inner wall of the box.

[0016] As an optional technical solution, a rotating shaft is provided at the bottom of the box surface, a box door is rotatably connected to the surface of the rotating shaft, and a handle is provided on the surface of the box door.

[0017] The utility model technical solution has the following advantages:

[0018] 1. The utility model drives the threaded rod to rotate through a servo motor, and the rotation of the threaded rod drives the scraper on the surface to move back and forth. The scraper slides in the groove on the surface of the first collecting box, and the oil and water flow into the first collecting box through the transport groove. Since the density of oil is relatively low, it usually floats on the water surface. When the scraper moves, the oil floating on the water surface is scraped through the groove into the second collecting box on both sides of the first collecting box, thereby separating the oil and water. The structure is relatively simple and the separation effect is good. There is no need to use a filter to filter the oil and water, and the use cost is low.

[0019] 2. The utility model injects steam into the connecting groove through the connecting pipe, so that the steam heats the inner wall of the box. The heating inside the box increases the temperature inside the box. After the temperature inside the box increases, it is effectively prevented that the oil on the surface of the oil-water mixture in the box solidifies when the equipment is working, thereby affecting the normal operation of the equipment. In addition, the continuous heating of the box effectively prevents the oil and water from solidifying in the box, thereby causing subsequent cleaning difficulties. BRIEF DESCRIPTION OF THE DRAWINGS
