[0002] Biomass conversion refers to the process of converting renewable biomass resources such as agricultural and forestry waste (such as straw, wood), algae, and organic waste into high-value products through physical, chemical, or biological methods. A catalyst is the "molecular scissors" for biomass conversion, which can transform low-value biomass into high-value energy and chemicals by reducing energy consumption, precisely cutting chemical bonds, and directionally synthesizing target products. Without a catalyst, biomass conversion will remain at an inefficient and high-cost stage and is difficult to replace fossil resources. Mixing catalyst raw materials can prepare a catalyst for biomass conversion.

The interior of the feeding pipe 3 is fixedly connected to a feeding pipe 301, and the interior of the feeding pipe 301 is slidably connected to a sealing plug 302. The sealing plug 302 can seal the port of the feeding pipe 301 to prevent dust from entering the interior of the feeding pipe 301 and the feeding pipe 3. When feeding is needed, it is only necessary to move the sealing plug 302 upward to separate it from the interior of the feeding pipe 301. The outer wall of the feeding pipe 3 is fixedly connected to a motor 2 303, and the output end of the motor 2 303 is fixedly connected to an auger blade 304, which is rotatably connected to the interior of the feeding pipe 3.

When the auger blade 304 rotates During the process, the catalyst raw materials can be transported, and slow transportation can be achieved so as to control the delivery amount of the catalyst raw materials. The end of the internal part of the feeding pipe 3 away from the feeding pipe 301 is fixedly connected with a feeding pipe 305, and the feeding pipe 305 is fixedly connected to the interior of the mixing barrel 2. The catalyst raw materials can enter the interior of the mixing barrel 2 through the feeding pipe 305. The bottom end of the internal part of the mixing barrel 2 is fixedly connected with a discharging pipe 4, and the lower end of the discharging pipe 4 is installed with a valve 401. During the process of mixing and stirring to prepare the catalyst, the valve 401 is in a closed state; when the catalyst preparation is completed and it needs to be discharged, it is only necessary to turn the switch of the valve 401 to open the valve 401, and the catalyst can enter the interior of the discharging pipe 4 through the bottom of the mixing barrel 2 and be discharged through the valve 401.
[0030] A method for preparing and using a catalyst for biomass conversion comprises the following steps: S1: Move the sealing plug 302 upward to separate it from the inside of the feeding pipe 301, and add the catalyst raw material into the inside of the feeding pipe 3 through the feeding pipe 301; S2: Start the second motor 303 to drive the auger blade 304 to rotate. The catalyst raw material is transported by the rotation of the auger blade 304. The catalyst raw material enters the interior of the mixing barrel 2 through the feed pipe 305; S3: Start the motor 1 203, which drives the rotating rod 204 to rotate. The rotating rod 204 also drives the connecting frame 1 206, the connecting column 207, the connecting frame 208 and the plurality of stirring rods 209 to rotate, thereby stirring and mixing the catalyst raw materials. S4: During the stirring and mixing process, start the electric telescopic rod 210 to drive the first connecting frame 206, the connecting column 207, the second connecting frame 208 and multiple stirring rods 209 to perform lifting adjustment, so that the first connecting frame 206 and the second connecting frame 208 are limited and slide inside the limiting groove 205, and the telescopic end of the electric telescopic rod 210 performs limiting activities inside the sliding groove 211, so that the first connecting frame 206, the second connecting frame 208 and multiple stirring rods 209 can perform lifting adjustment during the stirring and mixing of the catalyst raw materials, realizing that they can be fully stirred and mixed evenly when the amount of the catalyst raw materials is large; S5: After the catalyst raw materials are mixed and prepared, turn the switch of the valve 401 to open the valve 401, and then the prepared catalyst in the mixing barrel 2 is discharged through the discharge pipe 4 and discharged through the valve 401.
[0031] Working principle: When preparing the catalyst, first move the sealing plug 302 upward so that it slides upward and disengages from the inside of the feeding pipe 301. Add the catalyst raw material into the inside of the feeding pipe 3 through the feeding pipe 301. At the same time, start the second motor 303 to drive the auger blade 304 to rotate. During the rotation of the auger blade 304, the catalyst raw material is driven to move upward from bottom to top along the direction of the feeding pipe 3. The catalyst raw material enters the inside of the mixing barrel 2 through the feeding pipe 305. The rotation of the auger blade 304 is used to convey the catalyst raw material, which can not only achieve the effect of slow conveying, but also control the conveying amount of the catalyst raw material. After the catalyst raw material enters the inside of the mixing barrel 2, start the first motor 203 to drive the rotating rod 204 to rotate. Since the first connecting frame 206 and the second connecting frame 208 are both limited in the inside of the limiting groove 205, during the rotation of the rotating rod 204, the first connecting frame 206 and the second connecting frame 208 are driven to rotate, so that a plurality of stirring rods 209 fixedly connected to the lower surfaces of the first connecting frame 206 and the second connecting frame 208 rotate synchronously, thereby stirring and mixing the catalyst raw material. When the amount of the catalyst raw material in the mixing barrel 2 is relatively large, the electric telescopic rod 210 can be started to drive the first connecting frame 206, the second connecting frame 208 and a plurality of stirring rods 209 to perform lifting adjustment. Since the telescopic end of the electric telescopic rod 210 is limited and movable in the sliding groove 211 opened inside the first connecting frame 206, during the rotation of the first connecting frame 206, the second connecting frame 208 and a plurality of stirring rods 209 to stir the catalyst raw material, the telescopic end of the electric telescopic rod 210 can be controlled to reciprocally stretch and drive the first connecting frame 206, the second connecting frame 208 and a plurality of stirring rods 209 to perform reciprocating lifting adjustment, so that the catalyst raw material at different heights in the mixing barrel 2 can be stirred and mixed, and the catalyst raw material is fully stirred and evenly mixed, improving the preparation effect of the catalyst. Place the collecting device directly below the valve 401 in advance. When the catalyst preparation is completed, turn the switch of the valve 401 to open it. At this time, the prepared catalyst enters the inside of the discharge pipe 4 through the bottom of the mixing barrel 2 for blanking, and then enters the inside of the collecting barrel or collecting vessel through the valve 401. After the blanking is completed, turn off the switch of the valve 401.
[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
