Description

Technical Field

[0001] The present invention relates to the technical field of oil-water separation, and in particular to a rotary oil-water separator filtering device. Background Art

[0002] In daily life, people generally need to go to restaurants and hotels to eat. After eating in some restaurants and hotels, businesses often produce a lot of wastewater, which contains a certain amount of oil. With the improvement of environmental protection systems, oily wastewater cannot be discharged directly. It needs to be separated from the oil and water and can only be discharged after the quality meets the standards. Otherwise, it is easy to cause adverse effects on the ecological environment.

[0003] In most cases, an oil-water separator is required for oil-water separation. Existing oscillating oil-water separators have a slow separation speed, allowing wastewater to flow directly into the oil-water separator to separate the oil and wastewater. However, existing oil-water separators do not filter the wastewater during oil-water separation, which can easily cause food residue to contaminate the interior of the oil-water separator. Accumulating small amounts of these small residues can easily cause pipe blockages, and if left uncleaned for a long time, they can easily cause rotting and odor, which can adversely affect the subsequent use of the oil-water separator. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a rotary oil-water separator filtering device, which solves the problem that food residues contaminate the interior of the oil-water separator, some small residues accumulate and easily cause pipe blockage, and if they are not cleaned for a long time, they are likely to cause rotting and stinking, which can easily have an adverse effect on the subsequent use of the oil-water separator.

The lower right part of the outer surface of the air flotation machine 1 is fixedly connected with a drain pipe 3, which can discharge the water after the oil and water are separated from the drain pipe 3. The oil drain pipe 5 and the drain pipe 3 are both tilted downward at a certain angle, which can facilitate the liquid inside the air flotation machine 1 to be affected by gravity, so as to achieve the purpose of easy discharge. The upper left part of the outer surface of the air flotation machine 1 is fixedly connected with an oil drain pipe 5, which can discharge the grease after the oil and water are separated from the oil drain pipe 3. The top of the water inlet pipe 4 is fixedly connected, and the left side of the water inlet pipe 4 is fixedly connected with a truncated cone ring 6. A fixing ring 9 is placed on the left side of the truncated cone ring 6. The outer surface of the fixing ring 9 is fixedly connected with a rubber ring 10. The size of the rubber ring 10 is adapted to the outer surface of the fixing ring 9. The close fit between the rubber ring 10 and the outer surface of the fixing ring 9 can provide an anti-slip effect when the fixing ring 9 is rotated, thereby making it easier for the fixing ring 9 to rotate. The right side of the fixing ring 9 is fixedly connected with a circular slider 8, and a circular groove 7 is provided on the left side of the truncated cone ring 6. The circular groove 7 and the circular slider 8 are adapted to each other, which can achieve the purpose of fixing the fixing ring 9.

A thread groove 12 adapted to the thread 11 is provided inside the fixing ring 9. The thread 11 is threadedly connected to the thread groove 12, which can facilitate the fixing or disassembly of the cylinder 13. A filter body 19 adapted to the size of the inner side of the cylinder 13 is placed on the left side of the cylinder 13. By setting the filter body 19, a certain filtering effect can be achieved on the residue in the sewage. The upper part of the outer surface of the filter body 19 is fixedly connected to the limiting block 20. A slot 18 adapted to the size of the limiting block 20 is provided on the upper part of the outer surface of the cylinder 13. The front of the limiting block 20 is opened. A circular hole 21 is provided, and a fixed block 14 is fixedly connected to the upper part of the outer surface of the cylinder 13. The front of the fixed block 14 is clamped with a limit rod 17. The size of the limit rod 17 is adapted to the circular hole 21. The front of the limit rod 17 is fixedly connected to a circular block 15. A spring 16 is fixedly connected between the front of the fixed block 14 and the back of the circular block 15. The spring 16 is sleeved with the limit rod 17, which can facilitate the disassembly or installation of the filter body 19. The inner bottom wall of the flotation machine 1 is rotatably connected to a rotating rod 22. The upper part of the outer surface of the rotating rod 22 is fixedly connected to an umbrella-shaped filter plate 24. The umbrella-shaped filter plate 24 is in an umbrella state and has a through groove, so that when the umbrella-shaped filter plate 24 is rotated,The waste oil inside the flotation machine 1 can be concentrated on the upper surface of the umbrella-shaped filter plate 24, thereby facilitating waste oil collection. Two scrapers 23 are fixedly connected to the lower portion of the outer surface of the umbrella-shaped filter plate 24. The angle between the two scrapers 23 is a flat angle, and the two scrapers 23 can rotate as the rotating rod 22 rotates. Furthermore, the inner wall of the flotation machine 1 can be cleaned to a certain extent. An operating table 28 is fixedly installed at the rear portion of the outer surface of the flotation machine 1. The upper surface of the operating table 28 is fixedly connected to the motor body 25. The output shaft of the motor body 25 and the upper portion of the outer surface of the rotating rod 22 are both fixedly connected with pulleys 26. A belt 27 is connected between the two pulleys 26. When the output shaft of the motor body 25 rotates, it can provide power for the rotation of the rotating rod 22, thereby providing power for oil-water separation.

[0034] Working principle: When the oil-water separator needs to be used, first fix the output end of the water pump to the left side of the filter body 19, then connect the oil drain pipe 5 and the drain pipe 3 to the water pump respectively, and then pull the circular block 15. Through the coordinated setting of the cylinder 13, the circular block 15, the fixed block 14, the limit rod 17, the limit block 20 and the circular hole 21, the filter body 19 is then placed inside the cylinder 13. At this time, the circular block 15 is released, and the limit rod 17 can be inserted into the limit block under the influence of the tension of the spring 16. 20, to achieve the purpose of fixing the filter body 19, and then move the cylinder 13 to the right to make it contact with the fixing ring 9. At this time, through the cooperation of the thread 11 and the thread groove 12, the cylinder 13 can be fixed to the fixing ring 9 by rotating the fixing ring 9. The cooperation of the ring slider 8 and the ring chute 7 can make the fixing ring 9 rotate stably. At this time, the sewage is discharged into the interior of the flotation machine 1 through the water inlet pipe 4, and then the power of the flotation machine 1 is turned on to make it work. The grease in the sewage inside the flotation machine 1 is caused to float to the surface. Then, an external power source is connected to the motor body 25 to activate the motor body 25. Through the coordinated arrangement of the motor body 25, the pulley 26, the belt 27, and the rotating rod 22, the operation of the motor body 25 provides power for the rotation of the rotating rod 22. The umbrella-shaped filter plate 24 is provided to scrape the grease on the upper surface of the liquid inside the flotation machine 1, causing it to accumulate on the upper surface of the umbrella-shaped filter plate 24. Then, the water pump fixedly connected to the oil discharge pipe 5 is turned on to drain the grease on the upper surface of the umbrella-shaped filter plate 24. Then, the water pump fixedly connected to the drain pipe 3 is turned on to drain the separated water inside the flotation machine 1. The scraper 23 prevents the inner wall of the flotation machine 1 from being contaminated with grease. After the oil and water are separated, the filter body 19 can be disassembled by pulling the circular block 15, thereby facilitating the cleaning of the filter body 19 and further preventing the problem of small residues in the sewage from clogging the pipe.
