Problems solved by technology

However, in this method of putting the gas pipe into the liquid and then stirring, the gas will form bubbles after the gas is passed in, and it will float quickly, the contact area with water is small, and the contact time is short, so the gas utilization rate is not high. Lead to low production efficiency and increased production costs, which is not conducive to the development of enterprises

Embodiment 1

[0014] Embodiment 1: as figure 1 and figure 2 As shown, the present invention comprises frame 1 and support 2, and described support 2 is fixed on the frame 1, and described frame 1 is fixedly installed with reducer 3, and the input end of described reducer 3 is connected with motor 4. The output end is connected with a stirring shaft 5, the stirring shaft 5 is hollow inside, the upper end of the stirring shaft 5 is connected with the air inlet pipe 6 through a rotary sealing joint 11, and a disc turbine type curved blade stirrer 7 is provided at the lower end, so The disc turbine type curved blade agitator 7 includes a stirring disc 71 and a stirring curved blade 72, the stirring curved blades 72 are evenly distributed on the stirring disc 71, the bottom end of the stirring shaft 5 is located at the center of the stirring disc 71, and Have ventilated aeration hole 8.

Embodiment 2

[0015] Embodiment 2: Same as the above embodiment 1, wherein the motor 4 is connected with a frequency converter 9 , and the air inlet of the air inlet pipe 6 is provided with an aeration rate regulating valve 10 .

[0016] In the mixing process of the present invention, the gas is charged into the air intake pipe 6 by connecting the external air source at the air inlet of the air intake pipe 6, the aeration rate is controlled by the aeration rate regulating valve 10, the motor 4 works, and the reducer 3 is driven to work , so that the stirring shaft 5 rotates, and after the stirring shaft 5 is hollow, it communicates with the air inlet pipe 6 through the rotary sealing joint 11, the gas passes from the stirring shaft 5 into the liquid surface, overflows from the aeration hole 8, and the overflowing gas is moving upward At this time, it is blocked by the stirring disk 71, thereby turning to overflow to the side of the stirring disk 71. At this time, the gas overflowing sideways...

Abstract

The invention discloses a gas-liquid mixing and stirring device. The device comprises a frame and a base, the base is fixed on the frame, a decelerator is fixedly arranged on the frame, the input terminal of decelerator is connected to a motor, the output terminal of the decelerator is connected to a stirring shaft, which is hollow, the upper end of the stirring shaft is connected to an air-inlet pipe, the lower end of the stirring shaft is provided with a disc turbo-type curved agitator, and the bottom end of the stirring shaft is positioned on the center of the disc turbo-type curved agitator and is provided with a ventilated aeration hole. The gas-liquid mixing and stirring device has the advantages of simple structure and reasonable design, is capable of scattering bubbles to form small bubbles, and can enlarge the contact area between liquid and gas and prolong the contact time through stirring, so the gas and liquid can carry out reactions fully, the utilization rate of gas is increased therefore, the production speed is accelerated, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid mixing and stirring, and in particular relates to a gas-liquid mixing and stirring device. Background technique [0002] In traditional mixing and stirring devices, gas is generally added to the mixing tank and stirred by stirring blades to facilitate the mixing of gas and liquid. However, in this method of putting the gas pipe into the liquid and then stirring, the gas will form bubbles after the gas is passed in, and it will float quickly, the contact area with water is small, and the contact time is short, so the gas utilization rate is not high. It leads to low production efficiency and increased production costs, which is not conducive to the development of enterprises. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas-liquid mixing and stirring device with a simple structure and a reasonable design, which can fully and ef...
