[0023] Please see Figure 1-4 This utility model provides a technical solution: an oil-water separation and recycling device, comprising: a base 1, a tank 2, a siphon pipe 3, an oil outlet valve 4, and an oil-water injection assembly 5;
[0024] The tank body 2 is fixedly installed at the top of the base 1, the siphon pipe 3 is fixedly installed on one side of the tank body 2, and the bottom end of the siphon pipe 3 extends into the bottom end of the inner cavity of the tank body 2. The oil outlet valve 4 is installed on the other side of the tank body 2, and the oil-water injection assembly 5 is installed at the top of the tank body 2.
[0025] As a preferred option, a drain valve 6 is provided at the bottom of one side of the tank body 2 to facilitate the discharge of liquid inside the tank body 2. A top-mounted electric heater 7 is fixedly connected to the top of the tank body 2 via a flange, and one end of the top-mounted electric heater 7 extends into the bottom of the inner cavity of the tank body 2. By providing the top-mounted electric heater 7, the waste liquid inside the tank body 2 can be heated to improve the oil-water separation speed.
[0026] As a preferred option, the oil outlet valve 4 is positioned at a lower level than one end of the siphon tube 3, so that the separated waste oil and water can be discharged step by step.
[0027] To facilitate the separation of oil and water mixture in tank 2, a glass window 8 is embedded in the front side of tank 2. The upper and lower ends of the front side of tank 2 are respectively equipped with a maximum liquid level line 9 and an oil outlet line 10. The height of the oil outlet line 10 is lower than the height of the oil outlet valve 4. When the oil level after oil and water separation is lower than the oil outlet line 10, the oil outlet valve 4 is opened to drain the oil.
[0028] As a preferred embodiment, the oil-water injection assembly 5 further includes: an inlet cylinder 51, a reducing pipe 52, a first inlet pipe 53, a second inlet pipe 54, a clamp check valve 55, a retaining ring 56, an annular plate 57, a filter cartridge 58, and a lifting rod 59.
[0029] In order to allow the waste liquid to flow into the bottom of the tank 2 and prevent backflow, the inlet cylinder 51 is fixedly installed at the top center of the tank 2. The bottom end of the inlet cylinder 51 extends into the inner cavity of the tank 2 and is fixedly installed with a reducing pipe 52. The first inlet pipe 53 is fixedly installed at the bottom end of the reducing pipe 52. The second inlet pipe 54 is connected to the bottom end of the first inlet pipe 53 through a flange. The clamp check valve 55 is fixedly installed between the flanges of the first inlet pipe 53 and the second inlet pipe 54. The bottom end of the second inlet pipe 54 is arranged laterally to one side.
[0030] In order to simultaneously filter the waste liquid entering the tank 2, the retaining ring 56 is fixedly installed at the top of the inner cavity of the liquid inlet cylinder 51, the annular plate 57 is inserted into the inner cavity of the liquid inlet cylinder 51 and the annular plate 57 is located above the retaining ring 56, the filter cylinder 58 is fixedly installed at the bottom of the annular plate 57 and the filter cylinder 58 is inserted into the retaining ring 56, and the lifting rod 59 is fixedly installed at the top of the annular plate 57. The lifting rod 59 is provided to facilitate the removal of the filter cylinder 58.
[0031] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0032] The waste oil mixed with oil and water is poured directly into the liquid inlet cylinder 51. The waste oil is filtered in advance through the filter cylinder 58. The filtered impurities remain in the filter cylinder 58. By lifting the lifting rod 59, the annular plate 57 and the filter cylinder 58 can be removed to clean the inside of the filter cylinder 58 and directly filter the waste oil mixed with oil.
[0033] Waste oil entering the first inlet pipe 52 flows into the second inlet pipe 54 through the clamp check valve 55 and then into the tank 2. Due to the different densities of oil and water, they separate into layers, causing the oil to float to the water surface. By activating the top-mounted electric heater 7 to heat the liquid, the separation speed of the oil-water mixture can be improved. When the liquid overflows the siphon pipe 3, the water at the lowest layer in the tank 2 flows out through the siphon pipe 3 into the tank 2. Through the glass window 8, when the oil level line of the stratified layers is lower than the oil outlet valve 4 during the continuous injection of waste oil into the tank 2, the oil outlet valve 4 is opened to allow the separated oil to be discharged outward through the oil outlet valve 4. The separated oil can be accurately discharged through the observation of the glass window 8. The recovery efficiency is high, the operation is simple, and the simultaneous treatment of the mixed waste liquid saves space.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
