[0002] Water tanks can be used in many scenarios in life. According to the usage scenarios, they are divided into household water tanks and industrial water tanks. The structure of household water tanks is relatively simple and can meet daily water needs. However, due to the needs of different working environments, industrial water tanks need to have more functions. With the development of modern industry, the types of water tanks are also increasing, including water tanks that can separate oil from water. Oil-water separation tanks can reduce the impact of oil generated during industrial water discharge on the surrounding water quality, and can reduce the chance of environmental pollution.

[0003] Existing water tanks often filter and deodorize water through activated carbon filter plates when in use. After long-term use, the holes of the filter plates may be blocked and need to be removed and replaced, which is relatively complicated and has low work efficiency.

[0004] To this end, we propose a water storage tank for oil-water separation to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Reference Figure 1-3 A water storage tank for oil-water separation comprises a cylindrical box body 1, a rotating shaft 2 is rotatably connected to the top wall of the box body 1, a motor 3 for driving the rotating shaft 2 to rotate is fixedly installed on the top surface of the box body 1, a plurality of rotating plates 4 are fixedly connected to the upper end of the rotating shaft 2 in a circumferential array, a filter plate 5 is fixedly connected to the lower end of the box body 1, a movable plate 6 is slidably sleeved on the rotating shaft 2 between the rotating plate 4 and the filter plate 5, and a plurality of through holes for oil to pass through are provided on the movable plate 6, a through hole for inserting the rotating shaft 2 is provided at the center of the filter plate 5, a sleeve 7 is rotatably connected to the center of the filter plate 5, the lower end of the rotating shaft 2 is rotatably inserted into the sleeve 7, and the lower end of the sleeve 7 is fixedly connected to the circumferential array There are multiple scrapers 8 attached to the bottom surface of the filter plate 5, and a reduction assembly is arranged inside the sleeve 7 for reducing the rotation of the sleeve 7 through the rotating shaft 2. The side wall of the housing 1 is provided with an annular cavity 9 located outside the rotating plate 4, and an oil outlet pipe 10 is opened on one side of the bottom surface of the cavity 9. The rotating plate 4 is driven to rotate by the rotating shaft 2, so that the oil is driven into the cavity 9 to achieve oil-water separation. At the same time, the rotating shaft 2 cooperates with the reduction assembly to realize the reduction transmission of the sleeve 7, so that the scraper 8 can scrape and clean the bottom surface of the filter plate 5. Compared with the existing device, it avoids the problem that the holes of the filter plate 5 may be blocked after long-term use and need to be dismantled and replaced, thereby improving work efficiency.

[0022] Reference Figure 1-3 The number of rotating plates 4 is 3, and the rotating plates 4 are arc-shaped and rotate to cover the top surface of the movable plate 6, thereby achieving the rotation of the rotating plates 4 to guide the oil body into the cavity 9.

[0023] An annular baffle ring 11 is fixedly connected to one side of the bottom surface of the cavity 9 close to the rotating shaft 2. The annular baffle ring 11 can prevent excessive water from entering the cavity 9, thereby improving the separation effect.

[0024] The reduction assembly includes a ring gear 12 fixedly connected to the inner side of the sleeve 7, a sun gear 13 is fixedly sleeved on the rotating shaft 2 inside the ring gear 12, and a plurality of planetary gears 14 are rotatably connected to the bottom surface of the filter plate 5 between the sun gear 13 and the ring gear 12. One side of the planetary gear 14 engages with the ring gear 12 and the other side engages with the sun gear 13. The reduction transmission of the ring gear 12 is realized by the sun gear 13 cooperating with the planetary gear 14. The reduction transmission is used to prevent the scraper 8 from rotating too fast, causing the water body to be too turbid, thereby affecting the filtration and separation efficiency.

[0025] The number of scrapers 8 is three, and the scrapers 8 cover the filterable range of the filter plate 5 , thereby achieving complete scraping and cleaning of the filter plate 5 by the scrapers 8 .

[0026] Reference Figure 1 , Figure 4A water inlet pipe 15 is provided on one side of the box body 1 below the filter plate 5, a sewage pipe 16 is provided on the bottom of the box body 1, and a water outlet pipe 17 is provided on one side of the box body 1 above the filter plate 5. The filter plate 5 between the water inlet pipe 15 and the water outlet pipe 17 can ensure that the water in the water outlet pipe 17 is filtered.

[0027] The lower end of the water outlet pipe 17 is at the same height as the top surface of the filter plate 5, so as to output all the separated water as much as possible, avoid part of the filtered water flowing out through the sewage pipe 16, and improve the filtered water output rate.

[0028] Working principle:

[0029] When the water storage tank for oil-water separation is in use, the water to be treated is injected into the water storage tank from the water inlet pipe 15. At this time, the water body is first filtered by the filter plate 5, the motor 3 is turned on and drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the sun gear 13 to rotate, and cooperates with the planetary gear 14 to drive the ring gear 12 and the sleeve 7 to rotate at a reduced speed, so that the scraper 8 scrapes and cleans the bottom surface of the filter plate 5. After completion, the rising water level lifts the movable plate 6, and the oil moves to the top of the movable plate 6 through the through hole. When the movable plate 6 moves to the upper end, the rotating shaft 2 drives the arc-shaped rotating plate 4 to rotate, and the rotating plate 4 rotates and drives the oil into the cavity 9, and then outputs it through the oil outlet pipe 10. After completion, the water outlet pipe 17 is opened, and the water body after the oil is separated is output. After completion, the sewage pipe 16 is opened to output the sewage and dirt in the water storage tank. The above is the entire use process of the water storage tank for oil-water separation.

[0030] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
