DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-4 A gas-liquid mixing agitator includes a sleeve 100 and an inner tube 200. The inner tube 200 is movably connected to the inside of the sleeve 100. The outer wall of the inner tube 200 is provided with a mixing component, and the bottom of the sleeve 100 is provided with an adjusting component.

[0025] Among them, the mixing component includes a first stirring blade 201, the first stirring blade 201 is fixedly connected to the outer wall of the inner tube 200, the bottom end of the inner tube 200 is fixedly connected to the chassis 202, the outer wall of the chassis 202 is evenly fixedly connected to the second stirring blade 203, and the interior of the first stirring blade 201 is provided with an air outlet 204. The sleeve 100 and the inner tube 200 are both hollow shafts. They are placed into the liquid to be stirred through the device, and then the external gas supply equipment is connected to the device. When the first stirring blade 201 and the second stirring blade 203 rotate, the vacuum pressure generated causes the gas to be discharged from the air outlet 204, so that the gas is evenly distributed in the liquid, which greatly enhances the contact area between the gas and the liquid and can be better mixed with the liquid.

[0026] The second stirring blade 203 is semicircular in shape, and both ends of one side of the second stirring blade 203 are fixedly connected with concave blades 205, thereby enhancing the effect of the second stirring blade 203 on breaking up bubbles and particles.

[0027] The adjusting assembly includes a mounting block 206, which is fixedly connected to the bottom end of the sleeve 100. The mounting block 206 is internally rotatably connected to an adjusting block 207, and the mounting block 206 is internally movably connected to a fixed block 208. An adjusting slot 209 is provided on the right side of the inner tube 200, and an anti-slip block 210 is fixedly connected to the outer wall of the adjusting block 207. For tanks or containers of different sizes and heights, the adjusting block 207 can be rotated to the right by toggling the anti-slip block 210 to the right, so that the fixed block 208 is disengaged from the interference relationship with the inner tube 200, and the fixed state of the inner tube 200 is released. At this time, the inner tube 200 can be pulled outward to match the height of the corresponding liquid container. After the adjustment is completed, the anti-slip block 210 is toggled to the left to rotate the adjusting block 207 to the left, so that the fixed block 208 moves to the left, so that it interferes with the adjusting slot 209 on the outer wall of the inner tube 200, thereby fixing the inner tube 200. After fixation, stirring can be carried out.

[0028] The left side of the fixing block 208 is fixedly connected with an anti-skid pad, so that the inner tube 200 is fixed more firmly.

[0029] The interior of the anti-sliding block 210 is fixedly connected to a fixed shaft 211, and the outer wall of the mounting block 206 is fixedly connected to a buckle 212. The fixed shaft 211 matches the buckle 212. When fixing the inner tube 200, the anti-sliding block 210 is pushed to the left so that the fixed shaft 211 is engaged and enters the interior of the buckle 212, making its fixing state to the inner tube 200 more firmly.

[0030] Limit rods 213 are fixedly connected to both sides of the inner cavity of the mounting block 206 , and the limit rods 213 on both sides pass through the body of the fixing block 208 , thereby making the movement of the fixing block 208 more stable.

[0031] The inner wall of the sleeve 100 is evenly rotated and connected with an auxiliary wheel 214, and the auxiliary wheel 214 fits with the inner tube 200, so that the inner tube 200 can move up and down inside the sleeve 100 more smoothly.

[0032] Working principle: Place the device into the liquid to be stirred, and then connect the external air supply equipment to the device. The vacuum pressure generated when the first stirring blade 201 and the second stirring blade 203 rotate causes the gas to be discharged from the air outlet 204, so that the gas is evenly distributed in the liquid, greatly increasing the contact area between the gas and the liquid, and can better mix with the liquid. The second stirring blade 203 is semicircular, and both ends of one side of the second stirring blade 203 are fixedly connected with concave blades 205, thereby enhancing the second stirring blade 203's effect of breaking up bubbles and object particles. For tanks or containers of different sizes and heights, the anti-sliding block 210 can be toggled to the right to rotate the adjusting block 207 to the right, so that the fixing block 208 is out of contact with the inner tube 200, and the fixed state of the inner tube 200 is released. At this time, the inner tube 200 can be pulled outward to match the height of the corresponding liquid container. After the adjustment is completed, the anti-sliding block 210 is toggled to the left to rotate the adjusting block 207 to the left, so that the fixing block 208 moves to the left, so that it conflicts with the adjusting groove 209 on the outer wall of the inner tube 200, thereby fixing the inner tube 200. After fixation, stirring can be carried out.
