Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, and particularly relates to a grease recovery mechanism based on carbonized wool wastewater treatment. BACKGROUND

[0002] Carbonized wool is a process of removing plant cellulose substances in wool by chemical method combined with mechanical treatment according to the characteristics that wool is acid-resistant and plant matter is not acid-resistant. In the processing of carbonized wool, wool also needs to go through the process of washing wool. Wool grease is a kind of secreted grease attached to wool, which is a soft paste of light yellow or brown yellow, has viscosity and smoothness, has weak and specific smell, and will melt into wastewater during washing wool.

[0003] After the completion of washing wool and discharge, wool grease will be recovered from wastewater. At present, the traditional centrifugal separation method and extraction method are commonly used at home and abroad.

[0004] The centrifugal separation method is to separate wool grease from wastewater by using a high-speed centrifuge. At present, the separation is mainly performed by a disc centrifuge. Before centrifugal separation, the washing wool wastewater needs to be treated and heated.

[0005] Before entering the separator for separation, the washing wool wastewater needs to remove larger suspended particles by sedimentation and then be heated to enter the centrifuge to complete centrifugal separation to separate water phase, oil phase and residue phase. However, since the grease concentration suitable for centrifugal separation is generally above 15 g / L, when the concentration is lower than 10 g / L, the recovery rate of wool grease will be reduced. In general, the treatment process of wool grease-containing wastewater cannot help to increase the grease concentration in the waste liquid, so that the separated oil phase needs to be heated again for oil-water separation to obtain crude wool grease after recovery, which affects the wool grease recovery efficiency.

[0042] The control member 523 comprises a driving cylinder and a control support connected with the shielding table 522, the control support is slidingly installed through the bottom wall of the inner tank 4, the driving cylinder is arranged below the inner tank 4, and the driving end of the driving cylinder is connected with the control support, so that the control support and the shielding table 522 can be driven upward by the driving cylinder, the shielding of the shielding table 522 on the wastewater outlet pipeline 8 is released, the wastewater can stay in the inner tank 4 and the water-permeable filter 6, and after the water body is infiltrated under the action of water pressure, the shielding table 522 is controlled to move upward, and the wastewater after part of water is removed is led out of the wastewater outlet pipeline 8 to the subsequent process.

[0043] The top surface of the shielding table 522 is a conical surface, and the lower half of the shielding table 522 is a cylindrical body, and the edge of the cylindrical body is attached to the grease-proof permeable membrane 61.

[0044] As shown in Figure 7 When the wastewater stays in the inner tank 4, the wastewater stays on the inside of the grease-proof permeable membrane 61, at this time, the water body is pressed out of the grease-proof permeable membrane 61 under the action of water pressure, and the grease-proof permeable membrane 61 can prevent lanolin from infiltrating, and the position of the final wastewater outlet is at the wastewater outlet pipeline 8 below the shielding table 522, when the shielding table 522 moves upward, the wastewater will pass between the edge of the shielding table 522 and the grease-proof permeable membrane 61, at this time, the wastewater slowly flows between the shielding table 522 and the grease-proof permeable membrane 61, and in the process, the pressure increases, and the infiltration of the water body is further completed.
