[0015] The following is a further detailed description through specific implementation methods:

[0016] like Figure 1 As shown:

[0017] An industrial powder stirring device comprises a stirring tank 1, a stirring module and a pneumatic mixing module, wherein the stirring module stirs and mixes the powder in the stirring tank 1 in a mechanical manner, and the pneumatic mixing module stirs and mixes the powder in the stirring tank 1 by bursting microbubbles;

[0018] The pneumatic mixing module is installed at the inner bottom wall of the stirring tank 1, so that the microbubbles generated by the pneumatic mixing module can gradually rise from the bottom of the stirring tank 1 to the upper part of the stirring tank 1, and then the microbubbles gradually float to the top of the material distribution from the bottom of the material distribution, so as to better mix the material distribution. The stirring module is installed in the stirring tank 1 to mechanically stir and mix the powder in the stirring tank 1;

[0019] The pneumatic mixing module includes a high-pressure gas chamber 4, a plurality of air nozzles 5 and an air inlet connector 6. The high-pressure gas chamber 4 is adapted to the inner bottom wall of the mixing tank 1. The high-pressure gas chamber 4 is a bowl-shaped structure. A plurality of air nozzles 5 are evenly installed on the inner side of the high-pressure gas chamber 4, so that the pneumatic mixing module can form fine microbubbles at the bottom of the mixing tank 1. The air nozzles 5 are connected to the inside of the high-pressure gas chamber 4, so that the high-pressure air introduced into the high-pressure gas chamber 4 can enter the air nozzles 5. An air inlet connector 6 is provided at the bottom of the high-pressure gas chamber 4, and the air inlet connector 6 is used to connect to an external high-pressure gas source to inject high-pressure air into the high-pressure gas chamber 4.

[0020] The stirring module includes a driving mechanism, a plurality of stirring mechanisms and a lifting mechanism, wherein the driving mechanism is installed on the top of the stirring tank 1, the lifting mechanism is connected to the driving mechanism and is located inside the stirring tank 1, and the stirring mechanism is installed outside the lifting mechanism;

[0021] The driving mechanism is a driving motor 7, which is fixedly mounted on the top of the mixing tank 1 and the output shaft of the driving motor 7 is inserted into the mixing tank 1, so that the driving motor 7 can be connected to the lifting mechanism, thereby driving the lifting mechanism to rotate. The lifting mechanism includes a driving shaft 8 and a spiral fin 9. One end of the driving shaft 8 is connected to the output shaft of the driving motor 7 through a coupling. The driving shaft 8 is provided with a spiral fin 9. When the rotating shaft drives the spiral fin 9 to rotate, the powder at the lower part of the mixing tank 1 can be lifted to the upper part of the mixing tank 1, so that the powder at the upper and lower parts of the mixing tank 1 can be mixed more evenly.

[0022] Each stirring mechanism is evenly installed on the outside of the spiral fin 9. The stirring mechanism includes a stirring spring 11 and a counterweight 12. One end of the stirring spring 11 is fixedly connected to the outside of the spiral fin 9, and the other end of the stirring spring 11 is installed with a counterweight 12. The counterweight 12 is close to the inner wall of the stirring tank 1 and the counterweight 12 is separated from the inner wall of the stirring tank 1. When the spiral fin 9 drives the stirring spring 11 to move together, the stirring spring 11 stirs the powder while extending due to the influence of centrifugal force, so that the counterweight 12 at its end can intermittently hit the side wall of the stirring tank 1, so that the powder adhering to the inner wall of the stirring tank 1 can be shaken off.

[0023] The counterweight 12 is in a spherical structure.

[0024] One end of the driving shaft 8 away from the driving motor 7 is connected to the fixing seat 10 through a bearing, and the fixing seat 10 is fixedly installed at the bottom of the mixing tank 1. The fixing seat 10 at the bottom of the mixing tank 1 can make the operation of the driving shaft 8 more stable.

[0025] A feed inlet 2 is provided at the top of the mixing tank 1, and a discharge port is provided at the bottom of the mixing tank 1. The discharge port is located at the bottom of the fixed seat 10 and is separated from the fixed seat 10 to prevent the fixed seat 10 from obstructing the discharge of the discharge port.

[0026] A discharge valve 3 is installed at the discharge port, and the discharge valve 3 is used for opening and closing the discharge of the powder in the mixing tank 1.

[0027] The specific implementation process is as follows:

[0028] When the industrial powder stirring device is used, the powder to be stirred and mixed is transported into the stirring tank 1 through the feed port 2 at the upper part of the stirring tank 1, and then the stirring module and the pneumatic mixing module are started, and the driving motor 7 of the stirring module drives the driving shaft 8 to rotate, and the driving shaft 8 drives the spiral fins 9 to rotate, and the spiral fins 9 can lift the powder at the bottom of the stirring tank 1 to the upper part of the stirring tank 1, and the process is repeated; at the same time, the spiral fins 9 drive the stirring spring 11 and the counterweight hammer 12 to move together, and while the stirring spring 11 is stirring the powder, it will extend due to the influence of centrifugal force, so that the counterweight hammer 12 at its end can intermittently hit the side wall of the stirring tank 1, so that the powder adhering to the inner wall of the stirring tank 1 can be shaken off;

[0029] The air inlet connector 6 injects high-pressure air into the high-pressure air bin 4, and the high-pressure air in the high-pressure air bin 4 flows to the air nozzle 5, which sprays air to form microbubbles in the material distribution, so that the microbubbles gradually rise from the bottom of the material distribution, and stir and mix the powder material during the rising process; the stirring module and the pneumatic mixing work together to fully stir and mix the powder material in the stirring tank 1.

[0030] The industrial powder stirring device can stir and mix the powder in the stirring tank 1 through the stirring module. At the same time, when the stirring module rotates, the counterweight hammer 12 can extend and hit the side wall of the stirring tank 1 under the action of centrifugal force of the stirring spring 11, so that the powder adhering to the stirring tank 1 is shaken off, thereby reducing the possibility of powder accumulation in the stirring tank 1. The stirring module can lift the powder located at the lower part of the stirring tank 1 to the upper part of the stirring tank 1, and stir and mix it with the upper powder again, so that the powder is mixed more evenly; at the same time, the pneumatic mixing module can spray airflow at the bottom of the stirring tank 1, so that the airflow forms dense microbubbles in the powder in the stirring tank 1, and the microbubbles burst in the process of rising, thereby stirring the powder in the stirring tank 1, so that the powder in the stirring tank 1 is mixed and stirred more evenly.
