Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment, in particular to a high-concentration waste liquid low-temperature evaporation device. Background Art

[0002] High-concentration wastewater low-temperature evaporation equipment uses vacuum low-temperature evaporation technology to reduce the pressure inside the evaporator to lower the boiling point of the solution, thereby achieving evaporation and concentration of waste liquid at a relatively low temperature. Usually, high-concentration waste liquid includes industrial production, agricultural activities and domestic sewage.

[0003] Wastewater will form different water bodies in different areas. During the treatment process of some water bodies, because both oil and water have the characteristics of evaporation, oil needs to be treated separately during the treatment process.

[0004] According to the Chinese patent publication number CN221397439U, "A low-temperature evaporation device for high-concentration water separation and purification treatment", it mainly describes that under the rotation of the bidirectional screw, the two sliding covers can be moved to the sides or the middle at the same time, so as to facilitate the fixation of the outer cylinder, and a rotating seat and a support seat are provided on the upper surface of the base. When the two sliding covers move to the sides, the outer cylinder can be flipped, so that workers can better clean the residue inside the centrifugal barrel, making the cleaning of the residue more convenient. When the wastewater treated in this process enters the low-temperature evaporation equipment, the grease in the water will affect the overall treatment effect of the wastewater, and may also cause pollution and blockage to the evaporation equipment.

[0005] Therefore, a high-concentration waste liquid low-temperature evaporation equipment is proposed. By setting up a centrifugal cylinder, the first motor drives the rotating plate and the oil-water separation cover, so that the grease in the water body is fully centrifuged and then discharged uniformly. The grease attached to the inner wall of the centrifugal box can be dropped by the action of the driving gear and the gear ring, and then discharged uniformly. At the same time, after the water body enters the transfer box, the impurities in the water body will be retained by the filter frame, and can be taken out for treatment by opening the sealing plate, so as to solve the problem.
