The bottom of the tank body 1 is funnel-shaped for easy discharge, and a discharge port 11 connected to the inside of the tank body 1 is installed at the bottom of the tank body 1, and a control valve 10 is installed on the discharge port 11 to control the discharge of the tank body 1.

[0022] A motor 5 is fixedly installed on the top of the upper cover 2, and the output end of the motor 5 passes through the upper cover 2 downward and is installed with a first stirring shaft 13, and a first stirring rod is evenly fixedly installed on the outer circumference of the first stirring shaft 13. Two second bevel gears 14 are fixedly sleeved on the first stirring shaft 13, and the two second bevel gears 14 are arranged at intervals up and down. Two air inlet pipes connected to the interior of the tank body 1 are fixedly installed on the outer side of the tank body 1, and the two air inlet pipes are arranged at intervals up and down. A baffle 16 is fixedly installed at one end of the air inlet pipe close to the tank body 1, and gas nozzles 17 connecting the tank body 1 and the inside of the air inlet pipe are evenly installed on the baffle 16 along its circumference, and a one-way valve is installed on the gas nozzle 17, and the one-way valve ensures that the gas can only enter the inside of the tank body 1 from the inside of the air inlet pipe.

[0023] The second stirring shaft 15 is rotatably mounted at the center of the baffle 16. The second stirring shaft 15 is arranged horizontally, and a second stirring rod is fixedly mounted on the outer periphery of the second stirring shaft 15. A first bevel gear 12 is fixedly sleeved on one end of the second stirring shaft 15, and the first bevel gear 12 is meshed with the corresponding second bevel gear 14. One end of the second stirring shaft 15 extends to the inside of the air intake pipe and a fan blade 19 is fixedly mounted. A fixing plate 18 is fixedly mounted in the air intake pipe, and the second stirring shaft 15 passes through the center of the fixing plate 18 and is rotatably mounted with the fixing plate 18. The fixing plate 18 supports the second stirring shaft 15, so that the second stirring shaft 15 rotates stably.

[0024] A filter 8 is fixedly installed at one end of the air inlet pipe away from the tank body 1, and the filter 8 filters dust and impurities in the air. A connecting shaft is fixedly installed at one end of the second stirring shaft 15 away from the first bevel gear 12, and the connecting shaft passes through the filter 8 and is rotatably mounted with the filter 8.

[0025] The working principle of a catalytic reaction device for preparing ambroxol hydrochloride provided by the utility model is as follows:

[0026] When in use, the stopper 4 is opened, and materials are added into the tank body 1 through the feeding pipe 3. After the addition is completed, the stopper 4 is plugged in. The starting motor 5 drives the first stirring shaft 13 to rotate, and the first stirring shaft 13 drives the first stirring rod to rotate to stir the materials in the tank body 1. At the same time, the first stirring shaft 13 rotates to drive the second bevel gear 14 to rotate, and the second bevel gear 14 drives the first bevel gear 12 to rotate, and the first bevel gear 12 drives the second stirring shaft 15 to rotate, and the second stirring shaft 15 drives the second stirring rod to stir the materials in the tank body 1. The first stirring rod and the second stirring rod stir the materials at the same time, so that the materials are fully mixed and the reaction rate between the materials is accelerated.

[0027] When the second stirring shaft 15 rotates, it also drives the fan blades 19 to rotate. During the rotation of the fan blades 19, the external air can be drawn into the air inlet pipe through the filter screen 8. The air in the air inlet pipe is then sprayed into the tank body 1 by the gas nozzle 17. Since the air contains oxygen, oxygen is transported into the tank body 1. This is conducive to the catalytic reaction of the material better and faster, and it is not easy to have uneven oxygen in the upper and lower parts, thereby further improving the reaction efficiency of the material. When the second stirring shaft 15 rotates, it also drives the brush 9 to rotate. The brush 9 can continuously clean the filter screen 8 to prevent the accumulated impurities on the outer surface of the filter screen 8 from affecting the filtering effect.

[0028] When the pressure in the tank body 1 is relatively high, the solenoid valve 7 is opened, and then the gas inside the tank body 1 can be discharged through the exhaust pipe 6 to prevent the device from being damaged by excessive pressure. After the reaction is completed, the control valve 10 is opened to discharge the material from the discharge port 11.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
