The water tank is internally provided with a float switch, the water level of the water tank is kept constant through the float switch, and stable fluid delivery of the booster pump is ensured.
The water outlet pipeline of the water tank is connected with a booster pump, is also connected with a regulating valve and a flowmeter and is then connected with the ejector.
The ozone water mixing device of the utility model can provide ozone water flow with different specifications by the adjusting valve, and the flow meter is used for displaying different rated flow.
The ejector is a stainless steel part and consists of a nozzle, an air suction chamber, a throat pipe, a suction inlet, a mixing pipe and a sealing gasket.
After tap water on the water outlet pipeline of the water tank is pressurized and enters the nozzle of the ejector, high-speed fluid is formed at the nozzle. Under the action of high-speed fluid of the nozzle, stable negative pressure is formed in the air suction chamber, ozone is sucked into a flow channel of the ejector through the suction inlet, and the problem that the inlet of the pump is weak and unstable in self-suction capacity when the vortex pump with small flow and small power works is solved.
In the jet device, the jet device sucks ozone gas into a mixing pipe of a throat pipe, and the ozone gas and high-speed water flow are mixed to complete the first mixing of ozone water, so that ozone water with certain concentration is obtained. However, ozone gas is large bubbles in the fluid, so the gas-liquid mixing rate is not high, and the mixing rate of ozone is about 18% after testing. Therefore, the ozone water generated by the primary mixing enters the vortex pump again for secondary mixing.
The volute pump is a stainless steel volute pump and has the functions as follows: firstly, reduce motor power, realize the miniaturization of volute pump product. Secondly, realize the secondary mixing of gas-liquid degree of depth, further improve the mixing efficiency of ozone in the liquid.
The vortex pump has the characteristic of high output lift, but brings large energy loss and low efficiency, and the efficiency is about 30% generally. To maintain high lift output, the motor power must be increased. In order to reduce the power loss of the vortex pump, the ozone water pump is selectively applied to occasions with low lift, such as household and medical ozone water machines, and the output of the ozone water is low pressure.
Ozone water output by the ejector enters a flow passage of the vortex pump, ozone bubbles in the fluid are crushed into micron-sized micro bubbles and uniformly distributed in the liquid under the high-frequency impact of high-speed liquid in the groove of the impeller and the stirring of high-density longitudinal vortex fluid, the two-phase fluid completes a second mixing process in the vortex pump, and the mixing rate of the ozone in the ozone water is about 69%.
After primary mixing and secondary mixing, high-efficiency gas-liquid mixing efficiency can be obtained, and high-concentration ozone water is obtained, wherein the flow of the ozone water is 80-130 liters/h.
The utility model discloses the water that will come from the water tank passes through the booster pump and gets into the ejector, and in the ejector, the water that comes from the water tank and the ozone gas that comes from ozone generator carry out once mixing, and the ozone water that once mixes the production once more gets into the volute pump and carries out the secondary and mix to obtain efficient gas-liquid mixing efficiency, obtain the ozone water of high concentration.
