Air flotation scum fishing equipment

Номер: CN115947412A
Автор: LAN QINGQUAN, HUANG JING, ZHANG XIAOYUE
Принадлежит:

The invention relates to air flotation scum salvage equipment which comprises an air flotation box, a vertical partition plate is fixed between the front wall and the back wall of an inner cavity of the air flotation box, side plates parallel to the partition plate are fixed to the front side and the rear side of the upper surface of the air flotation box correspondingly, and salvage mechanisms used for salvage of scum are arranged on the side plates. Two vertical supporting strips are fixed to the back face of the air floating box, and a collecting mechanism is arranged on the supporting strips. According to the air flotation scum salvage equipment, when the salvage mechanism is used for salvage of a scum layer, due to the fact that the salvage plate is provided with the water holes for liquid to penetrate through, the liquid pushed by the salvage plate and entering the collecting mechanism is reduced, the situation that the salvage effect is affected due to the fact that the liquid level ...

Принадлежит:

The invention relates to the field of bonsai planting, in particular to a pottery basin with breathable and impermeable effects. Impermeable and breathable particles are arranged on the inner wall of the impermeable and breathable pottery basin. The preparation method comprises the following steps of applying a mixture with organosilane and solvent to the inner wall surface of the pottery basin; and performing grafting reaction on the mixture so as to obtain the impermeable and breathable pottery basin. The surface of the impermeable and breathable pottery basin is not wetted by water, so that micropores in the impermeable and breathable pottery basin are not blocked, external air can enter the basin through the micropores, and the breathing performance of the bonsai container is guaranteed. Moreover, the impermeable and breathable pottery basin has water retention, fertilizer maintenance and breathing effects simultaneously.

The invention relates to a waste hydraulic oil regenerating method and waste hydraulic oil regenerating equipment. The regenerating method comprises the following processes: an impurity sediment process, an impurity coarse filtering process, a heating process, a membrane separation process and a backwash process. In the membrane separation process, a porous ceramic membrane is adopted, the back-flushing pressure is 0.1 to 1.0MPa, the back-flushing time is 5 to 40 seconds, and the back-flushing time interval is 0.25 to 3 hours. The regenerating equipment is characterized by being applicable tothe waste hydraulic oil regenerating method disclosed by the invention and at least comprising a pretreatment device, a membrane filtering device and a back flushing device. When the method and the equipment are used, the process is simple, the operation is convenient, environment pollution is avoided, the efficiency is high, the energy consumption is low, and the waste hydraulic oil can be well purified ...
