Technical Field

[0001] The utility model relates to the field of oil-water separation devices, in particular to oil-water separation equipment for hotels and restaurants. Background Art

[0002] The hotel and catering industry generates a large amount of oily wastewater during its daily operations. If this oily wastewater is discharged directly without effective treatment, it will cause serious pollution to the urban drainage network and the environment, such as causing pipe blockages and eutrophication of water bodies. Traditional oil-water separator devices basically drain the grease from food waste through a simple static method. However, there is actually a considerable amount of solid grease in food waste, which is intertwined with solid waste. Traditional oil-water separator devices have difficulty separating this grease. In addition, the purity of the grease produced by traditional oil-water separators is relatively low, and it contains a large amount of small particles of solid waste.

[0034] Furthermore, the two-phase oil-water separation device 6 includes a waste oil overflow port 18, a power unit 19, a rotating gate 20, a main housing 21, a rotating bearing assembly 22, a wastewater overflow port 23 and a liquid inlet 24; the main housing 21 is mounted on the overall equipment frame 8 through the rotating bearing assembly 22, and the inlet end of the main housing 21 is mounted with a rotating gate 20. The waste oil overflow port 18, the liquid inlet 24 and the wastewater overflow port 23 are all connected to the main housing 21 through a flexible joint.

The waste oil overflow port 18 is fixedly connected to the oil hole inside the rotating gate 20 through a flexible joint. The liquid inlet 24 and the wastewater overflow port 23 are both connected to the filtrate pumping system 7. A pulley is mounted on the main housing 21, and the pulley is connected to the power unit 19 through a pulley.

[0035] In this embodiment, the main housing 21 is tubular and rotatably connected to a rotating bearing assembly 22, which is fixed to the overall device frame 8. The rotating gate 20 is bolted to the main housing 21 and moves in a circular motion with the main housing 21. A pulley is mounted on the main housing 21 and connected to the power unit 19 via a pulley.

[0037] The working principle of this utility model is:

[0038] First, food waste is poured into the collection hopper 9 of the device of the present invention. Then, the spiral blades 11 stir and convey the food waste, further dispersing the incoming clumps of food waste. The stirring and sorting rods 12 further beat the food waste, causing the solid fat inside to flow out into the filtrate collection hopper 17 inside the device, and then flow to the filtrate collection box 5 of the next system.

[0039] Subsequently, the filtrate pumping system 7 pumps the preliminarily separated grease inside the filtrate collection box 5 into the two-phase oil-water separator 6 inside the equipment. High-speed centrifugal motion is used to perform a secondary fine separation on the preliminarily separated grease, thereby obtaining purer grease. The two-phase oil-water separator 6 separates the oil-water mixture into an aqueous phase and an oil phase. The aqueous phase flows into the wastewater recovery tank 3, and the oil phase flows into the grease recovery tank 4. The entire separation process uses the solid-liquid separator 2 to perform a preliminary separation of food residue from the oil-water mixture. The food residue is collected in the food residue waste collection tank 1, further improving the oil-water separation efficiency and reducing wastewater pollution.

[0040] Solid-liquid separator 2 extracts food residue from wastewater using spiral blades 11 and agitating and sorting rods 12. The residue enters food residue and waste collection tank 1, while the liquid portion seeps into filtrate collection hopper 17 and flows to filtrate collection tank 5 for further processing. Filtrate pumping system 7 is responsible for transferring the filtrate from filtrate collection tank 5 to two-phase oil-water separator 6, ensuring smooth and stable liquid flow.

[0041] In the two-phase oil-water separator 6, the oil-water mixture enters the rotating gate 20. Centrifugal force separates the oil and water into different outlets, flowing into the grease recovery tank 4 and wastewater recovery tank 3, respectively. After treatment, the wastewater passes through the wastewater recovery tank 3 for subsequent water treatment, while the grease can be further recovered for other treatments.

[0042] It should be noted that all control methods described in this utility model are achievable within the existing technology, and all processes involved, such as liquid pumping, oil-water separation, and food residue separation, are generally known technologies. For example, the filtrate pumping system 7 is used to pump an oil-water mixture, and the two-phase oil-water separator 6 utilizes a rotary gate 20 for oil-water separation. All system components can be controlled using commonly available equipment based on actual needs. The structures of all components not specifically described are also known, such as the spiral blades 11, rotary gate 20, and rotating bearing assembly 22.

[0043] The above describes the specific implementation methods of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above implementation methods. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
