Summary of the invention:
The utility model is in order to solve the existing the problems referred to above of prior art, a kind of miniature solid particle that can effectively remove in the aquaculture water to be provided, and improves cultivation water pH value and helps the cyclic culture water body air-float purification equipment of oxygenation.
Technical solution of the present utility model is: a kind of cyclic culture water body air-float purification equipment, it is characterized in that: water inlet pipe 1 is arranged, water inlet pipe 1 is by valve 2, under meter 5, vacuum meter 10 joins with the inlet of gas-liquid mixing pump 11, also be connected to inlet pipe 12 with the inlet of gas-liquid mixing pump 11, inlet pipe 12 is provided with gas meter 13, valve 14, the outlet of gas-liquid mixing pump 11 and dissolving 15 join, dissolving 15 is by tensimeter 18, outgas post 22 in valve 19 and the air flotation tank 23 joins, be connected to foam removal pipeline 21 with the upper end of air flotation tank 23, the lower end of foam removal pipeline 21 places in the foam receiving tank 20, the lower end of air flotation tank 23 and rising pipe 25 join, and are connected to valve 24 on the rising pipe 25.
Be provided with vapor pipe 17 in the upper end of described dissolving 15, vent valve 16 is arranged on the vapor pipe 17.
Be connected to intercepting sewer 3 with the inlet end of described valve 2, intercepting sewer 3 is connected on the water inlet pipe 8 between under meter 5, the vacuum meter 10 by valve 4, water inlet pipe 8 between intercepting sewer 3 and the under meter 5 joins with water shoot 7, water discharge valve 6 is arranged on the water shoot 7, valve (9) is arranged on the water inlet pipe 8 between intercepting sewer 3 and the vacuum meter 10.
The utility model is that gas-liquid mixing pump and dissolving and air-flotation column are in series, microparticle in the aquaculture water there is very strong decontamination effect improving, the clearance of microparticle (with turbidometer) is more than 75%, simultaneously because effective removal of microparticle, reduced organic content, cultivation water pH value is improved.Because the dissolving in of air, dissolved oxygen concentration can increase by 30%~60% in the aquaculture water in addition.The utility model has also made full use of waterhead, and the foam concentrate matter of air-flotation column top is collected in the foam collection device by the overflow effect, has reduced energy consumption, has reduced purification cost and labor intensity of operating personnel.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: water inlet pipe 1 is arranged, water inlet pipe 1 is by valve 2, under meter 5, vacuum meter 10 joins with the inlet of gas-liquid mixing pump 11, also be connected to inlet pipe 12 with the inlet of gas-liquid mixing pump 11, inlet pipe 12 is provided with gas meter 13, valve 14, the outlet of gas-liquid mixing pump 11 and dissolving 15 join, dissolving 15 is by tensimeter 18, outgas post 22 in valve 19 and the air flotation tank 23 joins, be connected to foam removal pipeline 21 with the upper end of air flotation tank 23, the lower end of foam removal pipeline 21 places in the foam receiving tank 20, the lower end of air flotation tank 23 and rising pipe 25 join, and are connected to valve 24 on the rising pipe 25.Air flotation tank 23, foam receiving tank 20 can place on the operator's console 26, and air flotation tank 23 bottoms join by ring flange 27 and operator's console 26.
Too much for preventing the liquid in the dissolving 15, pressure is excessive, is provided with vapor pipe 17 in the upper end of described dissolving 15, and vent valve 16 is arranged on the vapor pipe 17, remaining gas can be discharged by vent valve.Pressure for buffer traffic meter 3, also for 6 in case of necessity as discharge pipe line, be connected to intercepting sewer 3 with the inlet end of described valve 2, intercepting sewer 3 is connected on the water inlet pipe 8 between under meter 5, the vacuum meter 10 by valve 4, water inlet pipe 8 between intercepting sewer 3 and the under meter 5 joins with water shoot 7, water discharge valve 6 is arranged on the water shoot 7, and the water inlet pipe 8 between intercepting sewer 3 and the vacuum meter 5 joins with valve 9.
