Description

High-efficiency water-gas mixing device

The present invention is a high-efficiency water-air mixing device. The pump system is a double-layer design. The interior is equipped with a double-layer impeller. The upper layer is a blower, the lower layer is a water pump, and there is a guide air and water flow between the two layers. The isolation turntable, the blades of the blower and the water pump are respectively installed on the upper and lower sides of the isolation turntable. The air and water are respectively guided to the venturi through the scroll shell. The front section of the venturi tube is connected to the fan to drive the air and the water flow driven by the water pump. The rotation of the pump blades pushes the water flow through the pump volute to guide the water flow to the outlet. The flow rate is very fast. The water and the air pushed by the fan enter the back section of the venturi, and then mix to produce a good mixing effect of water and air, and the jet of water drives the mixed water and air to flow forward under the water surface.

According to this, in aquaculture, environmental protection industrial wastewater treatment plants, and certain chemical plants, there are places where a good mixing reaction of gas and liquid is required; therefore, gas-liquid mixers have emerged.

1. Regarding the waterwheel commonly used in the aquaculture industry, it mainly uses a motor to drive the blades on the water surface. After the blades rotate, the water can be splashed into the air and refined. When the splashed water falls back At the time in the pool, the water droplets are in contact with the air, thus absorbing the oxygen in the air to achieve the function of aeration and provide breathing for the reared fish.

2. Another device is shown in my country's new patent No. 316496, which is an encircling reaction tank with a traction sleeve. The reaction tank is equipped with two sets of blades. When the motor rotates the blades, the blades will reduce the bubbles on the one hand, and at the same time It also causes vortex flow to increase the fineness of bubbles and increase the reaction time between gas and liquid.

3. There is another device such as a pool water aeration and oxygenation device shown in my country's new patent No. 362353, which is a double-layer aeration and oxygenation device. The impeller in the pump is divided into upper and lower layers. The upper layer is a water pump, and the lower layer It is an air pump that uses a motor to drive the impeller so that the impeller uses its rotating centrifugal force to forcefully push out the water and air in the chamber from the outlet to generate a water flow to activate the pool water, which can achieve the purpose of aeration and oxygenation in the water.

It can be seen from the above that the conventional inflator has the following defects:

1. Waterwheels in the aquaculture industry have the following shortcomings:

1. Only the water in the shallow water area can absorb the oxygen in the air;

2. The waterwheel will overturn in a typhoon;

3. Low efficiency;

4. The structure device is complex and easy to malfunction; it requires a power motor, a large reduction ratio reducer and multiple sets of blade devices, and the service life of general reducers is relatively short (about 3 months of service life).

2. Although the reaction tank type device has good efficiency, it also has the following shortcomings:

1. The device is complex and expensive. It not only needs a trough, two sets of blades, a power motor, and a reducer, but also an air pump;

2. More power consumption;

3. Only the liquid in the tank can react with the gas.

3. Pool water aeration and oxygenation devices can effectively mix water and air, but there are the following deficiencies:

1. The water inlet of the pump is upward. When the pump is running and sucking in water, the water flow above the pump inlet will generate a vortex. When there is a vortex, the water level at the middle entrance of the pump will be concave. , Especially when the speed is fast and the flow is large. The depression of the inlet water level reduces the pressure of the water flow at the inlet of the pump, thereby reducing the efficiency of the pump.

2. The air inlet of the pump is below, and there is no effective isolation between the upper and lower layers. Based on the principle of buoyancy, the air in the lower layer will naturally enter the upper water pump. Since air and water enter the water pump at the same time, the efficiency of the water pump will be greatly reduced, and the spraying distance of the water stream will be greatly reduced, thus reducing the scope of aeration and oxygenation.

3. When the device is directly used in a marine aquaculture farm, due to the corrosive nature of seawater, water vapor tends to invade the motor bearings when the motor is running, thus reducing the service life of the motor.

In addition, Xizhi also provides a "double-deck high-efficiency water-gas mixing device" of China's new patent publication No. 595316 and the "high-efficiency water-gas mixing device" of No. 595315, which does not have the venturi The design of pipe water and air mixing, so the efficiency of water and air mixing is not enough. Moreover, although No. 595316 adopts double-layer impeller and has an isolation platform to prevent air from mixing into the water pump, its double-layer impeller system is a flat design. The isolation design will make the mixing of water and air not meticulous. In addition, there is no setting of venturi, so the efficiency of water and air mixing is still extremely limited, which does not meet the requirements of today's use.

In view of this, our inventors devoted themselves to further research on the mixing of water and air, and proceeded to develop and improve, hoping to develop a better invention to solve the above problems, and after continuous experimentation and modification, the present invention came out.

The upper and lower layers of the pump have the design of diversion of the scroll shell, and are connected with a vent tube; the front section of the vent tube is connected to the fan to drive the air and the water flow driven by the pump. The rotation of the pump blades pushes the water flow through the pump scroll shell. Guided to the outlet, the flow velocity is very fast, and the suction force is generated at the inward contraction of the venturi, which attracts the air from the outlet of the blower. The water pushed by the water pump and the air pushed by the fan enter the back section of the venturi, and then mix to produce a good water and air mixing effect. The jet of water drives the mixed water vapor to flow forward under the water surface. The invention has power saving and good water and gas mixing effect. Because water and gas with high oxygen content are to be pushed under the water surface, generally the gas pressure must be greater than the water pressure gas to be sent to this depth. In other words, a larger blower power consumption is required . The venturi tube provides suction to make up for the insufficient air pressure of the small fan, so it can save electricity and has the effect of water and air mixing.

The isolation turntable is further provided with at least one hole up and down, and the holes are gradually expanded from top to bottom, so as to make part of the water flow of the water pump. It can enter the blower through the hole, so that the water flow can be atomized in the blower, so that the mixed gas after the water and gas is mixed is more detailed; the fan fins and the water pump fins are arranged on the non-inclined surface of the isolation turntable .

According to the above-mentioned high-efficiency water-air mixing device, the fan blades are arranged near the outer edge of the isolation turntable, and the water pump blades are arranged near the center below the isolation turntable Therefore, the radius of rotation of the fan blades is larger, and the radius of rotation of the water pump blades is smaller, so that the water flow can be pressurized by air in the gas-liquid mixing tube to facilitate uniform water-gas mixing in the gas-liquid mixing tube Squirting.

According to the above-mentioned high-efficiency water-gas mixing device, the gas-liquid mixing tube has a mixing flow channel, and the mixing flow channel is further provided with a partition plate in the front section of the gas-liquid mixing tube, thereby forming an upper section The Venturi tube includes the upper tube and the lower tube, and the mixing channel is tapered to form the inner constriction at the back section of the gas-liquid mixing tube; The piping system is connected to the blower, the lower piping system is connected to the water pump, and the upper side tube and the lower side tube are tapered at one end relative to the pump, and the rear end of the gas-liquid mixing tube is provided with The output port.
