Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.

As shown in Figure 1,3, waste liquid aeration tank in the cupric electrolysis production, including pond 1, Roots blower 2, more aerations Pipe 3, the bottom of pond in the pond 1 are provided with tilting section 11 and horizontal segment 12, the angle between the tilting section 11 and horizontal segment 12 For obtuse angle；Fixed at the air outlet of the Roots blower 2 to be equipped with whirlwind distribution pipe 4, the whirlwind distribution pipe 4 includes outer tube 41st, inner tube 42, said inner tube 42 are internally provided with helical blade 421, and helical blade 421 and the inwall of inner tube 42 fix company Connect；The end set of said inner tube 42 has bearing 43, and the inner ring of bearing 43 is fixedly connected with the end outer wall of inner tube 42, bearing 43 Outer ring is fixedly connected with the inwall of outer tube 41, and said inner tube 42 connects with outer tube 41, and the outer tube 41 goes out with Roots blower 2 Air port connects；The head end of the aeration tube 3 connects with inner tube 42, and the tail end of aeration tube 3 is arranged on the inside in pond 1.

In the bottom of pond in pond 1, tilting section 11 causes the horizontal segment 12 that the solid waste of precipitation easily accumulates under gravity, Horizontal segment 12 can not only be used as a buffer zone, and be also convenient for solid waste while the non-level of damage section subsequently cleared up above it 12.Whirlwind distribution pipe 4 is applied to the gas conveying and pressurization of low-pressure occasion, is distributed from the air outlet of whirlwind distribution pipe 4 to whirlwind What pipe 4 conveyed is forced air, and forced air is introduced into outer tube 41 in whirlwind distribution pipe 4, then into inner tube 42 In, forced air can drive inner tube 42 to rotate when impacting helical blade 421, while cause pressurization in the presence of reaction force Airflow portion is changed into spiral helicine air-flow, when the spiral helicine air-flow is aerated by liquid of the aeration tube 3 into pond 1, spiral The air-flow of shape is more concentrated and to drill through power stronger so that in aeration spiral helicine air-flow can deeper into enter liquid level deeper inside and It is not easy to spread, caused mixing, " stirring " effect are more excellent, and more preferably, the air-flow of loss is few, utilization rate for regional area dispersion effect Higher, aeration effect is notable.

Further, the angle between the tilting section 11 and horizontal segment 12 is α, 135 °≤α≤170 °.If α is excessive, The time that tilting section 11 precipitates solid waste can extend；If α is too small, the efficiency that tilting section 11 precipitates solid waste can be deteriorated.

Further, the tail end of the aeration tube 3 is fixedly provided with grid 31, and the lower section of grid 31 is provided with more flow-disturbing ropes 32, the head end of flow-disturbing rope 32 is fixedly connected with the inwall of aeration tube 3, and the tail end of flow-disturbing rope 32 is provided with minimum of one knot 321. In aeration, flow-disturbing rope 32 has orientation drainage so that the air-flow that the tail end of aeration tube 3 gushes out can be preferably along disturbing Stream rope 32 is stirred within the range, and aeration intensity is higher, disperse in unit range, mixed effect it is more preferable；And disturb Stream rope 32 aeration tube 3 inwall distribution as shown in figure 4, flow-disturbing rope 32 effect, not only cause the range of disturbance of flow-disturbing rope 32 Expand and concentrate, grid 31 has voltage equalizing.Knot 321 causes the tail end of flow-disturbing rope 32 to become heavier, is advantageous to flow-disturbing rope 32 naturally droop, and the volume at knot 321 is big, more excellent to the impact effects of liquid, further improve aeration, scattered effect Fruit.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
