[0023] By the above technical scheme, when the catalyst needs to be tested, the catalyst and the reactant are respectively put into the inside of the feeding hopper 5 first, then the second motor 15 is started by the external controller, the output end of the second motor 15 drives the spiral conveying rod 6 to rotate, so that the catalyst and the reactant can be fed into the inside of the reaction tank 3, and the spiral conveying rod 6 can be used for quantitative feeding, which avoids inaccurate testing caused by inaccurate feeding amount of manual feeding, thereby improving the testing rigor and accuracy of the catalyst. When the feeding of the catalyst and the reactant is completed, the first motor 8 is started by the external controller, the output end of the first motor 8 drives the stirring rod 4 and the first synchronous wheel 9 to rotate, the first synchronous wheel 9 drives the second synchronous wheel 11 and the rotating shaft 10 to rotate through the synchronous belt 12, the rotating shaft 10 drives the first gear 13 to rotate, so that the first gear 13 drives the second gear 14 and the reaction tank 3 to rotate through the meshing relationship, that is, the reaction tank 3 and the stirring rod 4 are driven to rotate in opposite directions, so that the catalyst and the reactant inside are fully stirred and mixed, the catalyst and the reactant are chemically reacted, and the gas or liquid product generated in the reaction process can be monitored and analyzed in real time. The device can be used for quantitative feeding of the catalyst and the reactant through the spiral conveying rod 6 during feeding, which avoids inaccurate testing caused by inaccurate feeding amount of manual feeding, thereby improving the testing rigor and accuracy of the catalyst. In the subsequent reaction test process, the reaction tank 3 and the stirring rod 4 can be driven to rotate in opposite directions, so that the catalyst and the reactant inside are fully stirred and mixed, the reaction effect is improved, and the testing accuracy is further improved.

[0024] Specifically, the inside of the reaction tank 3 is provided with an electric heating pipe 16, one side of the bottom of the reaction tank 3 is fixedly connected with a discharge port 17, the inside of the discharge port 17 is provided with a solenoid valve, the first motor 8, the second motor 15 and the solenoid valve are electrically connected with the external controller, the diameter of the second gear 14 is greater than that of the first gear 13, and the diameter of the second synchronous wheel 11 is less than that of the first synchronous wheel 9.

[0026] When testing the catalyst, firstly, the catalyst and reactants are placed into the feed hopper 5. Then, the second motor 15 is activated via an external controller.

The screw conveyor 6 allows for precise feeding, avoiding inaccuracies caused by manual feeding and improving the rigor and accuracy of catalyst testing. After feeding the catalyst and reactants, the first motor 8 is activated via the external controller.

The rotating shaft 10 then drives the first gear 13 to rotate, causing the first gear 13 to mesh with the second gear 14 and the reaction tank 3, thus causing the reaction tank 3 and the stirring rod 4 to rotate in opposite directions, thereby stimulating the internal catalyst... The catalyst and reactants are thoroughly stirred and mixed to allow for a chemical reaction. The gaseous or liquid products generated during the reaction can be monitored and analyzed in real time. This device can quantitatively feed the catalyst and reactants using a screw conveyor 6, avoiding inaccuracies caused by the inability to accurately control the feeding amount during manual feeding. This improves the rigor and accuracy of catalyst testing. Furthermore, during subsequent reaction tests, the reaction tank 3 and the stirring rod 4 can rotate in opposite directions, thoroughly stirring and mixing the catalyst and reactants inside, improving the reaction effect and further enhancing the accuracy of the test. The electric heating tube 16 allows for precise temperature control of the catalyst and reactants in the reaction tank 3. After the reaction is completed, the gaseous or liquid products generated by the reaction can be discharged by opening the solenoid valve, allowing for further testing. An external controller allows for quick and easy control of the first motor 8, the second motor 15, and the solenoid valve by the operator.
