Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separation, in particular to a self-cleaning oil separation and lifting device. Background Art

[0002] At present, the structure of the oil separation and lifting device for catering wastewater includes a solid-liquid separation unit, an oil-water separation unit, an oil collection unit, and a wastewater lifting unit. The treatment process is as follows: The oily wastewater enters the solid-liquid separation unit through the kitchen drainage pipe first. Inside the solid-liquid separation unit, there is a stainless steel grille to intercept the residues in the wastewater, and an automatic slag remover collects the residues into the residue bucket. The wastewater after slag separation enters the oil-water separation unit for oil-water separation. The separated oil is collected inside the oil collection unit and regularly collected for legal disposal. The treated wastewater enters the sewage lifting unit, and the wastewater is discharged into the outdoor sewage pipe network through the sewage lift pump.

[0003] The applicant of the present invention found that the prior art has at least the following technical problems:

[0004] 1. The design of the solid-liquid separation unit is unreasonable and lacks a cleaning mechanism. During the solid-liquid separation stage, the stainless steel grille is prone to accumulate food residues and oil mixtures, resulting in grille blockage, affecting the flow rate of wastewater, and requiring frequent manual cleaning, with low processing efficiency.

[0005] 2. The design of the oil-water separation unit is unreasonable and lacks a cleaning mechanism. After oil-water separation, the oil will condense on the inner wall of the oil-water separation unit. Long-term accumulation will lead to a decline in the separation effect and requires regular manual cleaning, with low oil recovery rate.

[0006] 3. The design of the sewage lifting unit is unreasonable and lacks a cleaning mechanism. Since the wastewater contains oil and suspended solids, these substances are prone to deposit and stick inside the sewage lifting unit, forming dirt that is difficult to clean, requiring frequent manual cleaning, and reducing the effective volume of the sewage lifting bin, with low processing efficiency.

[0007] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0032] As Figure 1 shown, the present utility model provides a self-cleaning grease separation and lifting device, including a solid-liquid separation tank 1, an oil-water separation tank 2, a sewage lifting tank 3 and a self-cleaning mechanism; the solid-liquid separation tank 1, the oil-water separation tank 2 and the sewage lifting tank 3 are sequentially connected along the wastewater flow direction; the self-cleaning mechanism includes a first spraying part, a second spraying part, a third spraying part and a main cleaning pipe 10, the first spraying part is located in the solid-liquid separation tank 1 and is connected to the drain pipe 301 of the sewage lifting tank 3 through the main cleaning pipe 10; the second spraying part is located in the oil-water separation tank 2 and is connected to the drain pipe 301 through the main cleaning pipe 10; the third spraying part is located in the sewage lifting tank 3 and is connected to the drain pipe 301; the drain pipe 301 is connected to the lifting pump 302 of the sewage lifting tank 3.

[0033] The wastewater enters through the water inlet 102 of the solid-liquid separation tank 1. A first spraying part is arranged in the solid-liquid separation tank 1. When the first spraying part is started, the treated wastewater from the drain pipe 301 of the sewage lifting tank 3 is received through the main cleaning pipe 10 as the cleaning water source to spray and clean the residues on the grille 101. The sprayed sewage and the untreated wastewater enter the oil-water separation tank 2 together.

[0034] A second spraying section is arranged in the oil-water separation tank 2. When the second spraying section is started, it also receives the treated wastewater from the drainage pipeline 301 of the sewage lift tank 3 through the main cleaning pipeline 10 as the cleaning water source, and sprays and cleans the inner wall of the oil-water separation tank 2. The impact force generated by the spraying is used to wash away the grease and dirt adhering to the inner wall, improving the oil separation efficiency and recovery rate.

[0035] A third spraying section is arranged in the sewage lift tank 3. When the third spraying section is started, it receives the treated wastewater from the drainage pipeline 301 of the sewage lift tank 3 as the cleaning water source, and sprays and cleans the inner wall of the sewage lift tank 3. The impact force generated by the spraying is used to wash away the grease and dirt adhering to the inner wall, effectively preventing the deposition of dirt in the sewage lift tank 3.

[0036] Through the coordinated action of the first spraying section, the second spraying section, the third spraying section, the main cleaning pipeline 10, the drainage pipeline 301 and the lift pump 302, the solid-liquid separation tank 1, the oil-water separation tank 2 and the sewage lift tank 3 are automatically cleaned by using the kinetic energy when the existing lift pump 302 drains water, improving the treatment efficiency and being environmentally friendly and energy-saving.

[0044] Furthermore, the third nozzle 6 adopts a spiral nozzle. Among them, the number of the third nozzles 6 can be designed as one, two, three or more according to the use requirements.

[0045] When the water level in the sewage lift tank 3 reaches the preset start-up water level of the lift pump 302, the lift pump 302 automatically starts, discharges the wastewater through the drainage pipe 301, conveys it to the third nozzle 6 through the third branch pipe 9, and sprays the water flow rotatably onto the inner wall and the bottom plate of the sewage lift tank 3, effectively flushing away the grease and dirt adhering to the inner wall and the bottom plate. The wastewater after spraying is mixed with the original wastewater in the sewage lift tank 3, and the wastewater in the sewage lift tank 3 is tested to judge whether it can be directly discharged into the outdoor sewage pipe network. If not, the cleaning process is repeated.
