Description

Technical Field

[0001] This utility model relates to the field of waste oil treatment technology in the catering industry, specifically to a heating tank for initial processing of waste cooking oil with oil-water separation. Background Technology

[0002] Oil-water separation and heating equipment is widely used in the catering industry, specifically for treating waste oily wastewater generated during catering processes. This equipment uses a series of physical and chemical processes to collect and recover the grease from the wastewater, while simultaneously purifying the water into environmentally compliant wastewater, which is then discharged into the municipal sewage system. In this process, the most commonly used wastewater discharge equipment is gravity-based oil-water separation equipment. This type of equipment utilizes the density difference between oil and water, causing the lighter oil to float to the top and the heavier water to sink to the bottom, thus achieving oil-water separation.

[0003] However, in actual use, the height of the oil-water interface often fluctuates due to factors such as temperature changes, fluctuations in influent flow, and changes in oil content. Traditional oil-water separation heating equipment has a significant problem: the height of the oil extraction pipe is fixed and cannot be adjusted in real time according to changes in the oil-water interface. This leads to a potential hazard: when the oil-water interface height changes, the fixed-height extraction pipe may fail to accurately extract pure oil or pure water, instead extracting an oil-water mixture. This not only reduces the efficiency and effectiveness of oil-water separation but may also cause the mixture to overflow, resulting in environmental pollution and safety hazards.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes an oil-water separation heating tank for the initial processing of kitchen waste oil, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A preliminary processing oil-water separation heating tank for kitchen waste oil includes a heating tank body, an oil extraction port at the top of the heating tank body, a corrugated pipe below the oil extraction port, a connecting ring fixedly connected to the outside of the corrugated pipe, one side of the connecting ring being connected to a moving rod via a connecting plate, one end of the moving rod passing through the heating tank body and connected to a moving plate, a drive motor fixed on the moving plate, the output end of the drive motor being connected to a gear via a rotating shaft, and the gear meshing with a rack.

[0008] Furthermore, the rack is fixedly connected to the fixed frame, one end of the fixed frame is fixedly connected to the heating tank body, the top of the fixed frame is equipped with a photoelectric sensor, the photoelectric sensor is electrically connected to the controller, the controller is located on the heating tank body, and the controller is electrically connected to the drive motor.

[0009] Furthermore, an ultrasonic sensor is installed at the top of the heating tank body, and the ultrasonic sensor is electrically connected to the controller.

[0010] Furthermore, the heating tank body is equipped with multiple nozzles, which are connected to the air inlet pipe, which is connected to the air storage tank, and the air storage tank is connected to the air compressor through a connecting pipe.

[0011] Furthermore, the top of the heating tank body is equipped with a liquid inlet pipe, which is connected to the filter box. The filter box is detachably connected to a filter screen and is connected to the heating tank body. The bottom of the heating tank body is equipped with a drain pipe.

[0012] Furthermore, the heating tank body is equipped with a heating tube, a temperature sensor and a pressure sensor, and an exhaust pipe at the top of the heating tank body.

[0013] Furthermore, the oil extraction port is connected to the oil extraction pipe, and the oil extraction pipe is connected to the oil pump.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By installing an adjustable-height corrugated pipe inside the heating tank, the position of the bottom of the corrugated pipe can be adjusted according to the height of the oil-water interface. The distance between the oil-water interface and the top of the heating tank can be measured by an ultrasonic sensor, and the distance between the top of the fixed frame and the moving plate can be detected by a photoelectric sensor. Thus, the distance between the bottom of the corrugated pipe and the top of the heating tank can be measured. By adjusting the height of the corrugated pipe, the efficiency and stability of the oil-water separation process can be ensured.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a heating tank for the initial processing of waste cooking oil with oil-water separation is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the oil-water separation heating tank for the initial processing of kitchen waste oil according to an embodiment of this utility model includes a heating tank body 1. The top of the heating tank body 1 is provided with an oil extraction port 2, which is connected to an oil extraction pipe 27. The oil extraction pipe 27 is connected to an oil extraction pump 28. A corrugated pipe 3 is connected below the oil extraction port 2. The corrugated pipe 3 is made of stainless steel. A connecting ring 4 is fixedly connected to the outside of the corrugated pipe 3. One side of the connecting ring 4 is connected to a moving rod 6 via a connecting plate 5. One end of the moving rod 6 passes through the heating tank body 1 and is connected to a moving plate 7. A drive motor 8 is fixed on the moving plate 7. The output end is connected to gear 9 via a rotating shaft. Gear 9 meshes with rack 10, which is fixedly connected to fixed frame 11. Limiting blocks are provided on both sides of the moving plate 7, and limiting grooves are provided inside the fixed frame 11. One end of the fixed frame 11 is fixedly connected to the heating tank body 1, and a photoelectric sensor 12 is provided at the top of the fixed frame 11. The photoelectric sensor 12 is electrically connected to controller 13, which is located on the heating tank body 1 and electrically connected to drive motor 8. An ultrasonic sensor 14 is provided at the top of the heating tank body 1 and is electrically connected to controller 13. Through this scheme, firstly, the ultrasonic sensor 14 measures distance by emitting and receiving ultrasonic signals. When the ultrasonic signal encounters the oil-water interface, a portion of the signal is reflected back. The sensor calculates the time difference between the emitted and received signals to determine the distance from the interface to the top of the tank. This distance data is transmitted to controller 13 in real time as an important basis for system height adjustment. Next, the photoelectric sensor 12 measures distance by emitting and receiving reflected light. When light shines on the moving plate 7, the reflected light is received by the sensor. By calculating the propagation time of the light, the distance between the top of the fixed frame 11 and the moving plate 7 can be determined. This distance data is also transmitted to the controller 13 for further calculation and control. After obtaining these two key distance data, the controller 13 performs a series of calculations. First, it adds the distance from the top of the fixed frame 11 to the moving plate 7 to the distance from the moving plate 7 to the connecting plate 5, and then subtracts the height of the fixed frame 11 to obtain the distance between the bottom of the bellows 3 and the top of the heating tank. Finally, by starting the drive motor 8, the system can adjust the height of the bellows 3. The drive motor 8 drives the gear 9 to rotate, thereby moving the moving plate 7. The movement of the moving plate 7 directly causes the bellows 3 to extend and retract, thus achieving height adjustment. The entire process is monitored and adjusted in real time by the controller 13 to ensure that the bellows 3 is always at the optimal height position, thereby achieving precise tracking and separation of the oil-water interface.

[0028] like Figures 1-4As shown, the heating tank body 1 has multiple nozzles 15 inside. The nozzles 15 are connected to the air inlet pipe 16, which is connected to the air storage tank 17. The air storage tank 17 is connected to the air compressor 18 through a connecting pipe. The top of the heating tank body 1 has a liquid inlet pipe 19, which is connected to the filter box 20. The filter box 20 has a detachable filter screen 21 inside and is connected to the heating tank body 1. The bottom of the heating tank body 1 has a drain pipe 22. The heating tank body 1 has a heating tube 23 inside. The heating tank body 1 has a temperature sensor 24 and a pressure sensor 25 inside. By setting the temperature sensor 24 and the pressure sensor 25, the internal temperature and pressure can be measured. The top of the heating tank body 1 has an exhaust pipe 26, which can discharge the gas inside the heating tank body 1 in a timely manner. The drain pipe 22, the air inlet pipe 16, and the exhaust pipe 26 are all equipped with electromagnetic valves. In the above scheme, the oil-water mixture is added into the filter box 20 through the inlet pipe 19, filtered through the filter screen 21, and then enters the heating tank. The oil-water mixture is heated by turning on the heating pipe 23. The air compressor 18 is then activated to compress the air to a high pressure state and stores it in the air storage tank 17. The compressed air is released into the liquid through the nozzle 15, forming a large number of tiny bubbles. These bubbles rise rapidly in the liquid, causing the surrounding liquid to flow. Due to the rapid rise of the bubbles, they effectively break the stillness of the liquid, promoting circulation and mixing within the liquid, and effectively promoting oil-water separation. After mixing, the oil-water mixture is allowed to settle. After sedimentation, the oil is extracted through the bellows pipe 3 and the oil extraction pipe 27, and the water is discharged through the drain pipe 22.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, by setting an adjustable-height corrugated pipe 3 inside the heating tank, the position of the bottom end of the corrugated pipe 3 can be adjusted according to the height of the oil-water interface. The ultrasonic sensor 14 can measure the distance between the oil-water interface and the top of the heating tank, and the photoelectric sensor 12 can detect the distance between the top of the fixed frame 11 and the moving plate 7. Thus, the distance between the bottom end of the corrugated pipe 3 and the top of the heating tank can be measured. By adjusting the height of the corrugated pipe 3, the efficiency and stability of the oil-water separation process can be ensured. By setting a nozzle 15, an air compressor 18, and an air storage tank 17, compressed air is used to generate bubbles. As the bubbles rise, they drive the liquid to flow, thereby achieving a stirring effect. This can effectively promote oil-water separation and improve stirring efficiency and uniformity.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
