Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to ultrasonic electrolysis flotation equipment. Background Art

[0002] The air flotation machine is a kind of water treatment environmental protection equipment mainly used for solid-liquid or liquid-liquid separation. It is suitable for oil-water separation, solid-liquid separation in paper mills, mud-water separation, low-temperature and low-turbidity surface water treatment, and solid-liquid separation of various other wastewaters.

[0003] Electrolytic flotation equipment uses an insoluble anode and cathode to directly electrolyze wastewater, and relies on the tiny bubbles of hydrogen and oxygen produced by electrolysis to float the flocculated suspended matter to the water surface, achieving the purpose of solid-liquid separation.

[0004] It has been found in actual use that the existing electrolytic flotation equipment has the following shortcomings:

[0005] The existing electrolytic flotation equipment uses a scraper to discharge slag. The frequency of the scraper is related to the thickness of the slag floating on the air flotation. The higher the thickness, the lower the water content. When the scraper discharges slag, the slag vibrates with the flow of water and decomposes into small sediments that sink into the sludge bucket, making it difficult to separate mud and water, affecting the effluent water quality.

[0006] When the scraper is discharging slag, the clean water at the bottom of the slag flows with the slag, and the clean water in the flotation area enters the sludge bucket, which will shake the settled sludge and increase the sludge output in the sludge bucket area. This may cause the sludge fluidity to deteriorate, block the sludge discharge pipe, and make the sludge concentration in the subsequent sludge pool too high, increase the viscosity, and make it difficult to lift;

[0007] Therefore, the present application provides an ultrasonic electrolysis flotation device to meet the demand. Utility Model Content

[0008] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose an ultrasonic electrolytic flotation machine equipment.

[0009] The technical problem to be solved by the utility model is to provide an ultrasonic electrolysis air floatation machine device to solve the problems of the existing ultrasonic electrolysis air floatation machine devices.

[0010] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0011] An ultrasonic electrolysis flotation device comprises: a treatment tank, an inlet pipe, an inflow chamber, a rectifying grid, an electrode group, a scraper, a sludge hopper, a sludge discharge pipe, a fixing frame, a cross bar, a baffle, a sleeve, a sludge chamber, a sludge discharge valve and a water outlet trough, wherein the inflow chamber is arranged on the left side of the treatment tank, the inflow chamber is arranged on the left side of the treatment tank, the rectifying grid is arranged at the lower end of the inflow chamber, the electrode group is arranged at the upper end of the rectifying grid, the scraper is arranged at the upper end of the treatment tank, the sludge hopper is arranged at the lower end of the treatment tank, the sludge discharge pipe is arranged at the bottom of the sludge hopper, a fixing frame is arranged on the inner wall of the treatment tank, a cross bar is arranged between the fixing frames, a baffle is arranged on the cross bar, a sleeve is arranged at the middle of the baffle, a sludge chamber is arranged on the right side of the treatment tank, a sludge discharge valve is arranged inside the sludge chamber, and a water outlet trough is arranged on the right side of the treatment tank.

[0012] Preferably, the sludge hoppers are provided in several groups, the sludge hoppers are funnel-shaped, and the sludge hoppers and the scraper are arranged opposite to each other.

[0013] Preferably, the mud discharge pipe transversely penetrates the inflow chamber and the treatment tank and extends to the left outer end of the treatment tank.

[0014] Preferably, the cross bar is installed in the middle of the sludge bucket and the scraper, and the cross bar spans the upper end of the sludge bucket.

[0015] Preferably, a plurality of groups of flow-blocking blocks are installed on the crossbar, and the flow-blocking blocks are in the shape of a disc.

[0016] Preferably, the baffle block is made of foam material, and the sleeve in the middle of the baffle block extends outward to the left and right ends of the baffle block.

[0017] Preferably, the diameter of the sleeve is larger than the diameter of the cross bar, and the baffle is movably connected to the cross bar through the sleeve.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] 1. Several groups of flow blocks on the crossbar can prevent the scum in the flotation zone from settling downward. Several groups of flow blocks can contact water and scum. Water can flow through the intervals between the flow blocks to prevent the scum in the flotation zone from settling downward into the sludge bucket of the flotation tank, thereby reducing sludge production and making the scraper discharge slag more smoothly, making the mud and water separation unobstructed, and ensuring the effluent water quality;

[0020] 2. The baffles made of foam material are relatively light. When encountering impact, the baffles can swing on the crossbar. The baffles can move away the scum and intercept the scum, thereby enhancing the viscosity of the water flow, which is conducive to the precipitation of high-density particles in the sludge hopper, ensuring the water content in the sludge hopper, and effectively avoiding the deterioration of sludge fluidity and clogging of the sludge discharge pipe.
