Description

TECHNICAL FIELD

[0001] The utility model relates to the grease production technical field, concretely is sewage treatment device for grease production. BACKGROUND

[0002] Soft-shelled turtle oil is a kind of natural oil obtained by special extraction process with soft-shelled turtle as raw material. Soft-shelled turtle oil is widely used in health products, cosmetics and pharmaceutical field due to its high nutritional value and medicinal value because of rich in various unsaturated fatty acids, vitamins and trace elements. In the production process of soft-shelled turtle oil, a certain amount of industrial wastewater will be produced. These wastewaters mainly come from oil extraction, separation and cleaning links, containing a large amount of oil residues, proteins, colloids and other organic substances. In addition, the wastewater also contains solid suspended matters such as meat scraps, bone particles and impurities. If these wastewaters are directly discharged without effective treatment, not only will cause environmental pollution, but also will waste the recyclable resources. Before treating these wastewaters, the solid matters in them need to be effectively filtered and removed to ensure the smooth progress of subsequent treatment process and improve the treatment efficiency.

[0003] The patent with publication number CN221637572U discloses a sewage treatment device for oil production, which comprises a separation tank installed on a support. The upper surface of the separation tank is provided with a feed inlet. A filter screen is fixedly installed on the inner wall of the separation tank near the feed inlet. A cleaning mechanism is arranged on the upper surface of the filter screen. The cleaning mechanism comprises a brush for cleaning large particle impurities and suspended matters on the filter screen. The sewage treatment device for oil production can effectively clean large particle impurities and suspended matters on the filter screen and maintain the normal operation of the filter screen by setting the cleaning mechanism. The brush is driven to rotate by a driving motor, so that the filter holes of the filter screen are cleaned. At the same time, a first suction pump sucks out the large particle impurities and suspended matters on the filter screen through a suction nozzle, thereby achieving the effect of cleaning the filter screen.

[0004] The prior art rotates the brush to clean the filter holes of the filter screen, and the first suction pump sucks out the large-particle impurities and suspended matters on the filter screen through the suction nozzle, so as to achieve the effect of cleaning the filter screen. However, the suction nozzle must be above the brush to avoid hindering the rotation of the brush when the brush rotates on the surface of the filter screen. This structure design has certain limitations. On the one hand, the position limitation of the suction nozzle causes the filter material to be accumulated on the upper side of the brush before the suction nozzle can smoothly suck out the filter material, which often takes a long time and reduces the cleaning efficiency of the filter screen. On the other hand, when the accumulation amount of the filter material is too large and even exceeds the height of the brush, the filter screen is partially or completely blocked, the filter holes are blocked, and the brush cannot effectively clean the accumulated impurities, thereby seriously affecting the normal operation and filtering efficiency of the entire device. In view of this, the grease production sewage treatment device is provided. Content of the utility model
