[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Specifically, raw materials are added to the catalyst processing equipment 4 through the feed valve 8. After adding the raw materials, we need to start the catalyst processing equipment 4 to start the catalyst processing work. In this process, the catalyst processing equipment 4 will prepare a catalyst that meets the requirements through processes such as mixing, crushing, and screening of the raw materials. Next, start the power fan 9, which is to extract the airflow from the outside and process the airflow through the drying box 11. After the airflow passes through the adsorption sponge 12 to remove water vapor, the purpose of drying the airflow is completed. The dried airflow is transported to the inside of the porous nozzle 14 and ejected through the continuous operation of the power fan 9. This step realizes the heat exchange of the catalyst processing equipment 4 and achieves the purpose of drying, cooling and heat dissipation. The airflow after heat exchange is discharged through multiple heat dissipation grooves 15, which effectively avoids the potential safety hazards caused by the high temperature of the catalyst processing equipment 4 during the production process. During the processing, the servo motor 5 also needs to be started. Its function is to transport the processed catalyst through the conveying equipment 6, and then extrude it through the outlet shell 7.

[0041] Reference Figure 1 and Figure 3The disassembly mechanism 2 includes two mounting plates 201, and the adjacent sides of the two mounting plates 201 are respectively arranged on the front and rear sides of the export shell 7, and the adjacent sides of the two mounting plates 201 are rotatably connected to two rolling bearings 202, and the top walls of the two mounting plates 201 are fixedly connected to the connecting shell 203, and the left sides of the inner walls of the two connecting shells 203 are fixedly connected to the electric telescopic rods 204, and the output ends of the two electric telescopic rods 204 are fixedly connected to the movable plates 205, and the upper and lower ends of the right sides of the two movable plates 205 are provided with engaging grooves 206, and the tops of the front and rear sides of the export shell 7 are fixedly connected to two engaging plates 207, and the left ends of the two engaging plates 207 are respectively engaged with the corresponding engaging grooves 206, and the upper and lower sides of the inner wall of the export shell 7 are rotatably connected to two rotating columns 208;

[0042] Specifically, the operator can start the two electric telescopic rods 204 to make the movable plate 205 at the output end move to the left at the same time. The key to this process is that the multiple engaging plates 207 and the corresponding movable plates 205 can be unlocked smoothly. This means that the left ends of the multiple engaging plates 207 and the corresponding engaging grooves 206 can be successfully separated, creating conditions for subsequent maintenance work. Next, the operator can pull the two connecting shells 203 so that the two mounting plates 201 and the rolling bearing 202 can be easily disassembled from the front and back sides of the output shell 7. The purpose of this step is to allow the rolling bearing 202 to be smoothly removed from the equipment for inspection and maintenance. Such a design greatly improves the flexibility of the device, makes the maintenance process more convenient, and also prolongs the service life of the device. By inspecting and repairing the rolling bearing 202, we can ensure the normal operation of the equipment, prolong the service life of the bearing, and improve production efficiency. At the same time, the efficiency and convenience of this maintenance solution also greatly reduce the labor intensity of the operator and improve work efficiency.

[0043] Reference Figure 1 , Figure 2 and Figure 3 , a control switch 18 is fixedly connected to the front side of the housing 3, and the control switch 18 is electrically connected to the catalyst processing equipment 4, the servo motor 5, the power fan 9 and the electric telescopic rod 204 respectively; a dust cover 19 is provided on the front side of the control switch 18, and the rear side of the dust cover 19 is rotatably connected to the front side of the housing 3 through a hinge; a filter plate 16 is fixedly connected to the right side of the drying box 11; two connecting plates 20 are fixedly connected to the front and rear sides of the workbench 1, and the inner walls of the multiple connecting plates 20 are fixedly connected to support columns 21;

[0045] Working principle: When starting to use, add raw materials into the catalyst processing equipment 4 through the feed valve 8, start the catalyst processing equipment 4, and make the device start to process the catalyst. By starting the power fan 9, the external airflow is extracted through the drying box 11, so that the airflow passes through the adsorption sponge 12 to remove water vapor, and the purpose of drying the airflow is completed. The dried airflow is continuously operated by the power fan 9, and is input into the interior of the porous nozzle 14 through the output pipe 13 and sprayed out, so that the catalyst processing equipment 4 can be heat exchanged, so as to achieve the purpose of drying, cooling and heat dissipation. The airflow after heat exchange is discharged through multiple heat dissipation slots 15, thereby avoiding the potential safety hazards caused by the high temperature of the catalyst processing equipment 4 in the production process and ensuring the safety of the operating personnel. In order to ensure the safety of the equipment, the servo motor 5 is started so that the processed catalyst is transported by the conveying device 6 and extruded through the outlet shell 7. When the rolling bearing 202 needs to be inspected and repaired, the two electric telescopic rods 204 are started so that the movable plate 205 at the output end thereof is simultaneously displaced to the left, so that the multiple engaging plates 207 are unlocked from the corresponding movable plates 205, that is, the left ends of the multiple engaging plates 207 are separated from the corresponding engaging grooves 206. Secondly, the two connecting shells 203 are pulled so that the two mounting plates 201 and the rolling bearing 202 can be disassembled from the front and rear sides of the outlet shell 7, thereby finally improving the flexibility of the device and increasing the service life of the device. In combination with the multiple rotating columns 208, it is convenient to export the processed catalyst.
