Description

Technical Field

[0001] This utility model relates to the field of clarification tank technology, specifically to a clarification tank based on the sedimentation of vegetable oils. Background Technology

[0002] A clarifier is a device specifically designed to treat wastewater containing vegetable oils. Through specific physical and chemical processes, it separates and settles the vegetable oils from the wastewater, thereby purifying the water. Typically, in a clarifier, the wastewater is first mixed with a coagulant, causing the suspended solids, colloids, and vegetable oils in the wastewater to form flocculants. Then, under the influence of gravity, the flocculants settle, and the clear water flows out from the top of the clarifier.

[0003] According to the Chinese patent publication number CN209522617U, "A clarification tank based on vegetable oil sedimentation", it mainly describes that by sliding the sliding seat box on the surface of the air flotation guide rail and the spline shaft and repeatedly scraping it up and down, the activated sludge adhering to the surface of the air flotation guide rail and the spline shaft can be removed, so as to prevent the activated sludge from affecting the clarification quality.

[0004] When treating vegetable oils, the effluent quality of the clarifier becomes unstable due to the complex and fluctuating composition of the vegetable oil wastewater. This includes emulsified oils, soluble oils, phospholipids, soaps, and other substances that form stable colloids or emulsions in the water, making it difficult for the oils to settle. In addition, some small-molecule oils will stick to the walls of the clarifier, increasing cleaning costs.

[0005] Therefore, a clarification tank based on the sedimentation of vegetable oil is proposed to solve the problem that some of the oil in the clarification tank will stick to the tank wall, increasing the subsequent cleaning cost. Utility Model Content

[0006] The technical problem this invention aims to solve is that some grease in the clarification tank will stick to the wall, increasing the subsequent cleaning cost. Therefore, a clarification tank based on the sedimentation of vegetable oil is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a clarification tank based on vegetable oil sedimentation, including a sedimentation tank, a treatment tank, and a dissolved air tank. A pressure pump is fixedly connected to the upper side of the dissolved air tank. A first pipe is fixedly connected to one side of the dissolved air tank. A water inlet pipe is fixedly connected to one end of the first pipe, and a first water pump is fixedly connected to one end of the water inlet pipe. A second pipe is fixedly connected to the bottom side of the dissolved air tank. An air inlet pipe is fixedly connected to one end of the second pipe, and a first air pump is fixedly connected to one end of the air inlet pipe. Electric ball valves are fixedly connected to both the first and second pipes. A delivery pipe is fixedly connected to the side of the dissolved air tank away from the air inlet pipe. The delivery pipe communicates with the treatment tank. A second water pump is fixedly connected to one side of the treatment tank. The output end of the second water pump communicates with the sedimentation tank.

[0008] As a preferred technical solution of this utility model, a drain pipe is fixedly connected to the output end of the second water pump. The drain pipe is made of a flexible pipe fitting. By changing the flow direction through the drain pipe, the flow velocity is reduced, which facilitates the mixing and treatment of water, thereby facilitating subsequent sedimentation and coagulation.

[0009] As a preferred technical solution of this utility model, a connecting ring is fixedly connected to one end of the drain pipe, and connecting plates are rotatably connected to both the upper and lower sides of the connecting ring. The connecting plates are fixedly connected to one side of the sedimentation tank to provide support for the drain pipe to change direction.

[0010] As a preferred technical solution of this utility model, a support plate is fixedly connected to the upper side of the treatment tank, and a second air pump is fixedly connected to the upper end of the support plate. A vertical pipe is fixedly connected to the output end of the second air pump. Air is guided by the second air pump and enters the treatment tank through the bottom side of the vertical pipe, which will form bubbles and increase the suspension effect of the vegetable oil.

[0011] As a preferred technical solution of this utility model, a horizontal pipe is fixedly connected to the bottom end of the vertical pipe, and air distribution pipes are evenly fixedly connected to both sides of the horizontal pipe. An atomizing nozzle is evenly fixedly connected to the upper end of the air distribution pipe. Through the air distribution pipe and the atomizing nozzle, the airflow entering the vertical pipe can be evenly atomized to form small bubbles, thereby improving the suspension effect of plant oils.

[0012] This invention has the following advantages: By installing a treatment tank and multiple dissolved air tanks on one side of the sedimentation tank, the wastewater can be pressurized and aerated, making the air bubbles carriers for the grease particles. When the wastewater enters the treatment tank, it passes through a second air pump, vertical pipe, horizontal pipe, air distribution pipe, and atomizing nozzles, which further enhances the generation of small air bubbles, causing the grease to float to the surface for easy cleaning. At the same time, setting this process before the wastewater enters the sedimentation tank reduces the effect of grease in the wastewater adhering to the sedimentation tank wall, thus reducing costs. Furthermore, the coordinated operation of multiple dissolved air tanks improves treatment efficiency and optimizes the wastewater treatment process. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The clarification tank shown includes a sedimentation tank 1, a treatment tank 2, and a dissolved air tank 3. A pressure pump 4 is fixedly connected to the upper side of the dissolved air tank 3. The dissolved air tank 3, in conjunction with the pressure pump 4, pressurizes the wastewater and air entering the dissolved air tank 3. A first pipe fitting is fixedly connected to one side of the dissolved air tank 3, with an inlet pipe 5 fixedly connected to one end of the first pipe fitting and a first water pump 6 fixedly connected to the other end of the inlet pipe 5. A second pipe fitting is fixedly connected to the bottom side of the dissolved air tank 3, with an air inlet pipe 7 fixedly connected to one end of the second pipe fitting and a first air pump 8 fixedly connected to the other end of the air inlet pipe 7. Electric ball valves are fixedly connected to both the first and second pipe fittings. The electric ball valves use a ball as the opening and closing element; rotating 90 degrees... It can be opened and closed quickly. Three electrically controlled ball valves are connected to the first water pump 6 and the first air pump 8 through wires. When the solution in the dissolved gas tank 3 reaches a certain height, a single electric ball valve closes. At this time, the first water pump 6 and the first air pump 8 supply to another dissolved gas tank 3. A delivery pipe 9 is fixedly connected to the side of the dissolved gas tank 3 away from the air inlet pipe 7. The delivery pipe 9 is connected to the treatment tank 2. A second water pump 10 is fixedly connected to one side of the treatment tank 2. Multiple sets of second water pumps 10 are set. The output end of the second water pump 10 is connected to the sedimentation tank 1. After the pressurized dissolved gas is completed, the water enters the treatment tank 2 from the delivery pipe 9. Then, the water flow rate is controlled by the second water pump 10, thereby increasing the reaction time between the bubbles and the vegetable oil.

[0019] The second water pump 10 is fixedly connected to a drain pipe 11 at its output end. The drain pipe 11 is made of a flexible pipe fitting, which can be bent and can be turned by control.

[0020] One end of the drain pipe 11 is fixedly connected to a connecting ring 12. Both the upper and lower sides of the connecting ring 12 are rotatably connected to connecting plates 13. The connecting plates 13 are fixedly connected to one side of the sedimentation tank 1. A drive motor is installed on the connecting plates 13 to drive the connecting ring 12 to rotate, which can guide the wastewater after oil removal and facilitate sedimentation.

[0021] The treatment tank 2 is fixedly connected to the upper side of a support plate 14. The upper end of the support plate 14 is fixedly connected to a second air pump 15. The output end of the second air pump 15 is fixedly connected to a vertical pipe 16. By setting the second air pump 15 to supply air through the bottom side of the vertical pipe 16, air bubbles are formed in the wastewater, thereby increasing the number of air bubbles.

[0022] The bottom of the vertical pipe 16 is fixedly connected to the horizontal pipe 17, and the two sides of the horizontal pipe 17 are evenly fixedly connected to the gas distribution pipes 18. The upper end of the gas distribution pipes 18 is evenly fixedly connected to the atomizing nozzles 19. Through the horizontal pipe 17, the gas distribution pipes 18 and the atomizing nozzles 19, the gas can be refined into small bubbles, which is convenient for reacting with vegetable oils.

[0023] Working principle: The first water pump 6 draws wastewater through the inlet pipe 5 and the first fitting into the dissolved air tank 3. The first air pump 8 draws air through the air inlet pipe 7 and the second fitting into the dissolved air tank 3. Then, the dissolved air tank 3 is pressurized by the pressurizing pump 4, and the water enters the treatment pool through the delivery pipe 9. At the same time, the second air pump 15 draws air through the vertical pipe 16, the air distribution pipe 17, the horizontal pipe 18 and the atomizing nozzle 19 to form small bubbles, increasing the contact between the bubbles and the wastewater, thereby causing most of the vegetable oil to precipitate and remain in the treatment pool 2. Then, multiple sets of water pumps 10 draw water from the treatment pool 2 into the sedimentation tank. The drive motor drives the connecting ring 12 and the drain pipe 11 to guide the sedimentation, which reduces the amount of vegetable oil entering the sedimentation tank 1, increases the maintenance cycle and reduces maintenance costs.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
