Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an integrated oil-water separation and air flotation device for pig farming wastewater. Background Technology

[0002] Chinese patent document CN214571139U discloses an integrated oil-water separation and flotation device for pig farm wastewater, including a shell. A vertically arranged partition plate is fixedly connected to the lower inner wall of the shell, and the height of the partition plate is lower than the height of the side wall of the shell. A diffuser plate is also fixedly connected between the inner side wall of the shell and the partition plate. Multiple motors are arranged below the diffuser plate, and each motor is fixedly connected to the lower inner wall of the shell. A wheel axle is fixedly connected to the output end of each motor, and multiple blades are fixedly connected to the side wall of each wheel axle. A scraping device is also provided inside the shell. The device has a simple structure, is easy to operate and install, and can issue a prompt when the filtration effect of the device is insufficient, which is conducive to timely cleaning of the device.

[0003] However, the scraper blades of the above-mentioned equipment also scrape off the wastewater when scraping oil, causing the water level to drop. The scraper blades gradually lose contact with the wastewater, and the oil and impurities cannot be discharged smoothly, causing the equipment to be unable to work continuously. To address this, we propose an integrated oil-water separation and flotation equipment for pig farm wastewater. Utility Model Content

[0016] (1) The integrated oil-water separation and flotation equipment for pig farm wastewater continuously introduces clean water into the treatment tank during the oil separation process through the water replenishment mechanism, so that the wastewater level continuously rises to remove oil and impurities on the surface of the wastewater and maintain the water level to ensure the continuity of oil separation. This solves the problem that some existing equipment scrapes oil but also scrapes off the wastewater, causing the water level to drop, making it difficult for the scraper to contact the wastewater, and preventing the oil and impurities from being discharged smoothly, thus causing the equipment to be unable to work continuously. This improves the practicality of the equipment.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution: an integrated oil-water separation and flotation device for pig farm wastewater, including a treatment tank 1, a flotation mechanism 4, and a water replenishment mechanism 3. A partition 2 is fixedly installed between the front and rear inner walls of the treatment tank 1, and the partition 2 is also fixedly connected to the bottom inner side of the treatment tank 1. The flotation mechanism 4 is set on the treatment tank 1 and is used to aerate the wastewater. A weighing device 5 is set at the bottom inner side of the treatment tank 1, and at least two sets of oil collectors 6 are placed on the top of the weighing device 5. A collection plate 7 with the number and position corresponding to the oil collectors 6 is fixedly installed on the outer surface of the other side of the partition 2. A set of slots is opened on both the front and rear inner walls of the treatment tank 1, and a limit plate 8 is slidably installed between the two sets of slots. A guide plate 9 is integrally formed on the outer surface of the other side of the treatment tank 1. A drain pipe 10 communicating with the interior is fixedly installed on the outer surface of the front side of the treatment tank 1. A display screen 11 and an alarm 12 are fixedly installed on the outer surface of the front side of the treatment tank 1.

[0025] The water replenishment mechanism 3 is installed on the treatment tank 1. The water replenishment mechanism 3 includes a water tank 31, a water pump 32 and a water supply pipe 33. The water tank 31 is fixedly installed on the front outer surface of the treatment tank 1. The water pump 32 is fixedly installed on the inner bottom of the water tank 31. The water supply pipe 33 is fixedly installed on the bottom of the water tank 31. One end of the water supply pipe 33 passes through the front side of the treatment tank 1 and extends into the interior of the treatment tank 1.

[0026] The water replenishment mechanism 3 also includes a tank cover 34. The other end of the water supply pipe 33 is connected to the output end of the water pump 32. The top of the water tank 31 is integrally formed with a water inlet that communicates with its interior. The tank cover 34 is threaded onto the water inlet. An installation hole is opened through the front side of the water tank 31. A water level window is installed in the installation hole. Through the water replenishment mechanism 3, during the oil separation process of the wastewater in the treatment tank 1, clean water is continuously supplied to the treatment tank 1, so that the wastewater level continuously rises to remove oil and impurities from the surface of the wastewater and maintain the water level to ensure the continuity of oil separation. This solves the problem that in some existing equipment, the scraper scrapes oil but also scrapes off the wastewater, causing the water level to drop, making it difficult for the scraper to contact the wastewater, and preventing the oil and impurities from being discharged smoothly, thus causing the equipment to be unable to work continuously. This improves the practicality of the equipment.

[0027] The flotation mechanism 4 includes an air pump 41, an air supply pipe 42, a hollow pipe 43, and an aeration pipe 44. The air pump 41 is fixedly installed on one outer surface of the treatment tank 1. The air supply pipe 42 is fixedly connected between the bottom of the air pump 41 and one outer surface of the treatment tank 1. The hollow pipe 43 is fixedly installed between one inner wall of the treatment tank 1 and one outer surface of the partition 2. At least two sets of aeration pipes 44 communicating with the interior of the hollow pipe 43 are fixedly installed on the outer surface of the hollow pipe 43. One end of the air supply pipe 42 communicates with the interior of the hollow pipe 43, and the other end of the air supply pipe 42 communicates with the output end of the air pump 41. Through the flotation mechanism 4, stable flotation aeration can be carried out in the wastewater, improving the removal effect of impurities in the wastewater. At the same time, under the action of the weighing device 5 and the oil collector 6, the staff can be promptly reminded to handle the oil when the oil collector 6 is full, ensuring the effectiveness of the equipment and facilitating the promotion and use of the device.

[0028] Working principle: Pour the pig wastewater to be treated into the treatment tank 1 until it is level with the partition 2. Control the air pump 41 to start, and air is introduced into the hollow tube 43 through the air supply pipe 42 and air bubbles are sprayed out from each aeration pipe 44 to aerate the wastewater. Impurities in the wastewater reach the surface of the wastewater with the air bubbles. Then, control the water pump 32 to start, and slowly introduce clean water from the water tank 31 into the wastewater through the water supply pipe 33 to raise the water level of the wastewater. The oil and impurities on the surface of the wastewater will then cross the partition 2 and flow into each oil collector 6 through each collection plate 7. The impurities and oil remain in each oil collector 6. Clean water seeps out from each oil collector 6 and is discharged through the guide plate 9. The weighing device 5 monitors each oil collector 6 in real time. When each oil collector 6 is full of oil and impurities, an alarm will be sounded through the alarm 12. The staff slides down the limit plate 8 and then removes each oil collector 6 for cleaning. After the wastewater treatment is completed, the drain pipe 10 is opened to discharge the wastewater.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
