[0002] In daily life, kitchen water is used for washing dishes, washing meat, and treating kitchen wastewater. The most common problem in the kitchen is oil stains, and kitchen wastewater is usually mainly composed of oil stains. Therefore, a wastewater treatment device that dissolves oil stains is needed to treat kitchen wastewater.

[0003] Kitchen wastewater contains a large amount of oil and solid waste, and existing wastewater treatment equipment cannot remove both solid waste and oil at the same time, thus affecting the efficiency of wastewater treatment. Utility Model Content

[0004] To solve the above problems, this utility model provides a wastewater treatment device for dissolving oil stains. This utility model is achieved through the following technical solution.

[0005] A wastewater treatment device for dissolving oil stains includes a wastewater treatment tank. A filter screen frame is rotatably connected inside the wastewater treatment tank. A conical filter screen is embedded inside the filter screen frame. A drain pipe is rotatably connected to the bottom end of the conical filter screen. A rotating frame is rotatably connected to the bottom end inside the wastewater treatment tank. A rotating rod is fixedly connected to the rotating frame. A second fixed frame is fixedly connected to one end of the rotating rod that passes through the drain pipe, and the second fixed frame is fixedly connected inside the filter screen frame. A defoaming grid is fixedly connected to the rotating frame. The device also includes a power mechanism for driving the filter screen frame and the rotating frame to rotate.

[0006] Furthermore, a sewage inlet hopper is connected through the top of the sewage treatment tank.

[0007] Furthermore, a hanging rod is fixedly connected to the top of the inside of the sewage treatment tank, and a diversion hood is fixedly connected to one end of the hanging rod, with the diversion hood located directly below the discharge port of the sewage input hopper.

[0008] Furthermore, a fixing rod is fixedly connected to the top of the filter frame, and a first gear is fixedly connected to one end of the fixing rod.

[0009] Furthermore, the power mechanism includes a servo motor, which is fixedly connected to the top of the sewage treatment tank. The output shaft of the servo motor is fixedly connected to a shaft, and a second gear fixed at one end of the shaft meshes with a first gear.

[0010] Furthermore, a first fixing frame is fixedly connected inside the sewage treatment tank, one end of the sewage pipe is fixedly connected to the first fixing frame, and the other end of the sewage pipe passes through the sewage treatment tank and extends to the outside.

[0011] Furthermore, an overflow channel and a drain pipe are connected through the outer surface of the sewage treatment tank, and a valve is installed at one end of the drain pipe.

[0012] The beneficial effects of this utility model are as follows: During operation, wastewater is first fed into the wastewater inlet hopper, and the flow guide hood directs the wastewater into the filter screen frame. The filter screen frame filters the wastewater through a conical filter screen. The filtered liquid enters the wastewater treatment tank, while the filtered solid waste is discharged through the drain pipe connected to the filter screen frame. This process achieves solid-liquid separation of the wastewater. Then, the power mechanism drives the filter screen frame and rotating frame to rotate. The filter screen frame causes centrifugal separation of the wastewater, improving the solid-liquid separation effect. The rotating frame stirs the wastewater, breaking up oil bubbles and causing the oil to float on the surface. The oil then overflows through the overflow channel and is discharged. Finally, the wastewater is discharged by opening the valve on the drain pipe. The structure is reasonable, facilitating solid-liquid separation of wastewater and removing oil, thus improving wastewater treatment efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, the present invention has the following specific embodiments.

[0025] Example:

[0026] A wastewater treatment device for dissolving oil stains includes a wastewater treatment tank 1. A filter screen frame 2 is rotatably connected inside the wastewater treatment tank 1. A conical filter screen 21 is embedded inside the filter screen frame 2. A drain pipe 22 is rotatably connected to the bottom end of the conical filter screen 21. A rotating frame 4 is rotatably connected to the bottom end inside the wastewater treatment tank 1. A rotating rod 41 is fixedly connected to the rotating frame 4. A second fixed frame 42 is fixedly connected to one end of the rotating rod 41 that passes through the drain pipe 22. The second fixed frame 42 is fixedly connected inside the filter screen frame 2. A defoaming grid 43 is fixedly connected to the rotating frame 4. The device also includes a power mechanism for driving the filter screen frame 2 and the rotating frame 4 to rotate.

[0027] By adopting the above technical solution, when using the device, sewage is first input through the sewage input hopper 11, and the diversion hood 3 guides the sewage into the filter frame 2. The filter frame 2 filters the sewage through the conical filter screen 21. The filtered liquid enters the sewage treatment tank 1, and the filtered solid waste is output through the drain pipe 22 connected to the filter frame 2, which can separate the sewage into solid and liquid. Then, the set power mechanism can drive the filter frame 2 and the rotating frame 4 to rotate. The filter frame 2 can drive the sewage to generate centrifugal separation, which can improve the sewage solid-liquid separation effect. The rotating frame 4 can stir the sewage, thereby breaking the oil bubbles in the sewage, which can make the oil float on the liquid surface and then overflow through the set overflow channel 12. Finally, the sewage can be discharged by opening the valve on the drain pipe 13. The structure is reasonable, which facilitates the solid-liquid separation of sewage and removes oil from the sewage, thereby improving the sewage treatment efficiency.

[0028] Specifically, a sewage inlet hopper 11 is connected through the top of the sewage treatment tank 1;

[0029] A suspension rod 31 is fixedly connected to the top of the inside of the sewage treatment tank 1. A diversion hood 3 is fixedly connected to one end of the suspension rod 31, and the diversion hood 3 is located directly below the discharge port of the sewage input hopper 11.

[0030] By adopting the above technical solution, the sewage input hopper 11 can input sewage into the sewage treatment tank 1, and the diversion hood 3 set directly below the sewage input hopper 11 can guide the input sewage, so that the sewage can flow and filter along the inner wall of the conical filter screen 21.

[0031] Specifically, a fixing rod 23 is fixedly connected to the top of the filter frame 2, and a first gear 24 is fixedly connected to one end of the fixing rod 23;

[0032] The power mechanism includes a servo motor 5, which is fixedly connected to the top of the sewage treatment tank 1. The output shaft of the servo motor 5 is fixedly connected to a shaft 51, and a second gear 52 fixed at one end of the shaft 51 meshes with a first gear 24.

[0033] By adopting the above technical solution, the power mechanism can simultaneously drive the rotating frame 4 and the filter screen frame 2 to rotate. That is, the servo motor 5 can drive the shaft 51 to rotate, and the shaft 51 drives the meshing first gear 24 to rotate through the second gear 52. The first gear 24 can drive the filter screen frame 2 to rotate through the fixed rod 23. The rotation of the filter screen frame 2 can cause the falling sewage to undergo centrifugal filtration. At the same time, the filter screen frame 2 drives the rotating rod 41 to rotate through the connected second fixed frame 42. The rotating rod 41 can drive the connected rotating frame 4 to rotate. The rotating rotating frame 4 can break the air bubbles in the sewage through the defoaming grid 43, so that the oil in the sewage can float on the surface of the liquid.

[0034] Specifically, a first fixing frame 14 is fixedly connected inside the sewage treatment tank 1, one end of the sewage pipe 22 is fixedly connected to the first fixing frame 14, and the other end of the sewage pipe 22 passes through the sewage treatment tank 1 and extends to the outside.

[0035] By adopting the above technical solution, the first fixing frame 14 can support and fix the sewage pipe 22, and the other end of the sewage pipe 22 can extend through the inside of the sewage treatment tank 1 to discharge solid waste from the sewage filtered by the filter screen frame 2.

[0036] Specifically, an overflow channel 12 and a drain pipe 13 are connected through the outer surface of the sewage treatment tank 1, and a valve is installed at one end of the drain pipe 13.

[0037] By adopting the above technical solution, the overflow channel 12 can discharge the oil spill on the surface of the sewage, and the drain pipe 13 can output the filtered wastewater.
