A heating roller 22 is fixedly installed in the fixed frame 21. An annular scraper 23 is slidably sleeved on the heating roller 22. Mirror-image distributed first nozzles 25 and second nozzles 26 are fixedly installed inside the annular scraper 23. Sprayers 27 are fixedly installed on both the first nozzles 25 and the second nozzles 26. Control valves 28 are fixedly installed on one side of the first nozzles 25 and the second nozzles 26. A discharge pipe 11 is fixedly installed at the bottom end of the reaction kettle 1, and one end of the discharge pipe 11 is fixedly connected to the control valve 28. The control valve 28 is a two-way reversing valve. First, raw materials for producing carbon aerogel powder need to be prepared. These raw materials include silica sol, gel catalyst, organic solvent, etc. Then the raw materials are put into the reaction kettle 1 for stirring and mixing reaction. After the raw materials are mixed, they are transported into the first nozzles 25 and the second nozzles 26 through the discharge pipe 11 and sprayed onto the heating roller 22 through the sprayers 27. In this process, the raw materials are quickly gelled on the heating roller 22 to form wet gel. The wet gel is quickly dried on the heating roller 22 to remove the moisture therein while maintaining its three-dimensional nano-porous structure. A heating device is provided in the heating roller 22 to provide the necessary heat. At the same time, the annular scraper 23 is reciprocally moved along the heating roller 22 to scrape off the dried gel on the surface of the heating roller 22. When the annular scraper 23 moves to the right, the second nozzle 26 on the right side of the annular scraper 23 is closed and the first nozzle 25 is opened through the control valve 28, and the raw materials are sprayed onto the heating roller 22 through the sprayer 27. When the annular scraper 23 moves to the left, the first nozzle 25 on the left side of the annular scraper 23 is closed and the second nozzle 26 is opened through the control valve 28, and the raw materials are sprayed onto the heating roller 22 through the sprayer 27. Thus, the purpose of continuously spraying raw materials for drying and simultaneously scraping off the dried gel on the surface of the heating roller 22 is achieved, greatly improving the production efficiency.

When the annular scraper 23 moves to the leftmost end of the heating roller 22, the toothed plate 282 touches the wall plate of the fixed frame 21 and drives the gear 281 to rotate to control the valve 28, so that the control valve 28 closes the second nozzle 26 on the right side of the annular scraper 23 and opens the first nozzle 25. When the annular scraper 23 moves to the rightmost end of the heating roller 22, the toothed plate 282 touches the wall plate of the fixed frame 21 and drives the gear 281 to rotate to control the valve 28, so that the control valve 28 closes the first nozzle 25 on the left side of the annular scraper 23 and opens the second nozzle 26.

[0025] By adopting the above technical solution, the reciprocating lead screw 53 rotates in the fixed rod 24.

[0026] A slider 531 is slidably clamped in the thread groove of the reciprocating lead screw 53. A connecting rod 532 is rotatably installed on the slider 531, and the bottom end of the connecting rod 532 is rotatably connected to the annular scraper 23.

[0027] By adopting the above technical solution, when the reciprocating lead screw 53 rotates, the slider 531 drives the connecting rod 532 to reciprocate in its thread groove, and the connecting rod 532 drives the annular scraper 23 to reciprocate along the heating roller 22.

[0029] By adopting the above technical solution, the annular scraper 23 scrapes off the dried gel on the surface of the heating roller 22 and drops it into the crushing device 3 for crushing treatment. The crushed gel powder drops into the outlet chute 4 and is discharged through the blanking pipe 41.

[0030] An outlet auger is rotatably installed in the outlet chute 4. Worms 52 are fixedly installed at one end of the outlet auger and one end of the reciprocating lead screw 53 respectively.

[0031] By adopting the above technical solution, the two worms 52 drive the reciprocating lead screw 53 and the outlet auger to rotate respectively, and the outlet auger drives the gel powder in the outlet chute 4 to be discharged through the blanking pipe 41.

[0036] Working principle: When the present utility model is in use, first, raw materials for producing carbon aerogel powder need to be prepared. These raw materials include silica sol, gel catalyst, organic solvent, etc. Then, the raw materials are put into the reaction kettle 1 for stirring and mixing reaction. After the raw materials are mixed, they are transported to the first spray pipe 25 and the second spray pipe 26 through the discharge pipe 11 and sprayed onto the heating roller 22 through the nozzle 27. In this process, the raw materials are rapidly gelled on the heating roller 22 to form a wet gel. The wet gel is rapidly dried on the heating roller 22 to remove the moisture therein while maintaining its three-dimensional nano-porous structure. A heating device is provided in the heating roller 22 to provide the necessary heat. At the same time, the motor 51 drives the double-headed worm 54 to rotate. The double-headed worm 54 drives the two worm wheels 52 to rotate. The two worm wheels 52 respectively drive the reciprocating lead screw 53 and the discharge auger to rotate. The rotation of the reciprocating lead screw 53 causes the slider 531 to drive the connecting rod 532 to reciprocate in its thread groove. The connecting rod 532 drives the annular scraper 23 to reciprocate along the heating roller 22. When the annular scraper 23 moves to the leftmost end of the heating roller 22, the tooth plate 282 touches the wall plate of the fixing frame 21 and drives the gear 281 to rotate to control the valve 28, so that the control valve 28 closes the second spray pipe 26 on the right side of the annular scraper 23 and opens the first spray pipe 25, and the raw materials are sprayed onto the heating roller 22 through the nozzle 27. When the annular scraper 23 moves to the rightmost end of the heating roller 22, the tooth plate 282 touches the wall plate of the fixing frame 21 and drives the gear 281 to rotate to control the valve 28, so that the control valve 28 closes the first spray pipe 25 on the left side of the annular scraper 23 and opens the second spray pipe 26, and the raw materials are sprayed onto the heating roller 22 through the nozzle 27. The annular scraper 23 scrapes off the dried gel on the surface of the heating roller 22 and drops it into the crushing device 3 for crushing treatment. The crushed gel powder drops into the discharge chute 4, and the discharge auger drives the gel powder in the discharge chute 4 to be discharged through the blanking pipe 41.
