Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to an automatic oil-water residue separation device. Background Art

[0002] For domestic oily sewage, especially kitchen sewage from the catering industry, oil-water separation must be carried out first to remove the oil in the sewage to meet the emission standards and meet the requirements of various subsequent sewage treatment processes. The recovered oil can also be further utilized for ecological purposes. There are many principles for separating oil and water in oil-water separation devices, mainly including coagulation, filtration and gravity sedimentation. Gravity sedimentation refers to the use of the different densities between oil and water. The density of oil is smaller than that of water, and oil always floats on the upper layer of water. Tools are used to remove the oil on the upper layer to achieve the effect of separating oil and water. The oil-water separation device currently used selects gravity sedimentation as the working principle and uses a rotating oil scraper impeller to remove the oil on the upper layer. Due to the rotation of the impeller, the oil and water are constantly mixed, which affects the sedimentation and reduces the oil-water separation effect.

[0003] The Chinese utility model patent with publication number CN213610111U discloses an automatic assisted oil discharge device for oil-water separation. By setting a protective plate, a support block and a positioning mechanism for coordinated use, the user can put the protective plate on the top of the support block, and the positioning mechanism enters the support block to achieve a clamping effect. The positioning mechanism achieves the positioning effect of the protective plate and the recovery filter box to prevent up and down movement, and solves the problem that the first step of existing sewage entering the oil-water separation equipment is to filter particles and residues in the sewage. However, the device still has some other problems. For example, the recovery filter box provided in the device is prone to clogging to a certain extent during use. Utility Model Content
