[0029] Please refer to the attached Figures 1-4 , a catalyst screening device, comprising a device body 10, a reactor body 13 is arranged inside the device body 10, a power switch 14 is arranged on the back of the device body 10, an upper cover plate 12 is arranged on the top of the device body 10, and a control component is arranged at the top end inside the device body 10;
[0030] The control component includes a mounting plate 15 fixed inside the device body 10. An infrared camera is provided on the mounting plate 15 corresponding to the reactor body 13. Photos at different time periods are taken by the infrared camera to further achieve efficient screening. Above the mounting plate 15, a mounting guide rail 16 is fixed. A temperature controller 17 and a PLC controller 18 are sequentially arranged on the mounting guide rail 16. The main function of the temperature controller 17 is to monitor and control the temperature to ensure that the temperature is maintained within the set range.

A cooling fan 20 is arranged on one side of the device body 10 near the temperature controller 17. A heat dissipation slot 11 is provided on the side of the device body 10 corresponding to the control component. The settings of the heat dissipation slot 11 and the cooling fan 20 facilitate the natural convection of air, enabling the internal hot air to be dissipated to the external environment more quickly, preventing the performance degradation or damage of components caused by overheating, and extending the service life of the equipment.
[0031] On one end surface of the device body 10, a power button 21, an emergency stop switch 22, a back pressure valve 23, and a plurality of ball valves 24 are provided.

The back pressure valve 23 can adjust the valve opening according to the system requirements, so that the fluid maintains a certain back pressure in the pipeline, avoiding the phenomenon of too fast flow rate or backflow caused by load changes, and ensuring the normal operation of the system. The ball valves 24 are used to control the on-off of the fluid.
[0032] On the side of the device body 10, a USB through-board 25 and a network cable dismounting board 29 are provided.

[0034] Magnetic strip 35 is provided on both the touch screen door frame 27 and the side plate 30. The magnetic strip 35 uses magnetic adsorption force to tightly fix the touch screen door frame 27 and the side plate 30 on the device body 10, ensuring that the touch screen door frame 27 and the side plate 30 can be firmly closed during the experiment, preventing the touch screen door frame 27 and the side plate 30 from accidentally opening due to the pressure generated by the internal reaction or other external forces, and ensuring the safety and stability of the experiment.

[0036] The working principle of the present utility model is as follows:
[0037] When in use, use an electronic balance to weigh the sample with the required mass, connect the device body 10 to an external power source, then pull the handle 31 to open the side plate 30, slowly pour the sample onto the reactor body 13 with weighing paper, then close the side plate 30, and the situation of the reactor body 13 can be observed at any time through the touch screen 26, which is convenient for the next operation. Turn on the power switch 14 and press the power button 21. At this time, the device body 10 starts to operate, and the reactor body 13 starts to react. The mass flowmeter 19 can monitor the gas flow rate in the device body 10 in real time and transmit the data to the PLC controller 18. The PLC controller 18 monitors the operating state of the device in real time, detects abnormal situations, adjusts the valve opening by turning the back pressure valve 23 and the ball valve 24, then raises it to the specified pressure and heats it to the target temperature. Then, an infrared camera is provided at the corresponding position of the reactor body 13 on the mounting plate 15 to take pictures at different time periods. If the device body 10 fails, the emergency stop switch 22 can be pressed in time to avoid further damage to the device body 10.
