[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-4 As shown, a crushing device for producing aerogel powder includes a crushing zone 3. A crushing sleeve 20 is fixedly connected to the inner side of the crushing zone 3. A crushing component is fixedly connected to the bottom of the crushing zone 3. Multiple air inlets are opened at the bottom of the crushing sleeve 20. Air jets 19 are installed in the air inlets. Backflush components are fixedly connected to the air inlets of the multiple air jets 19. A filter screen 23 is fixedly connected to the top of the crushing zone 3.

[0030] The crushing assembly includes a crushing motor 16 and a crushing blade 22. The crushing motor 16 is fixedly connected to the bottom of the crushing zone 3, the crushing blade 22 is fixedly connected to the power output end of the crushing motor 16, and the crushing blade 22 is rotatably connected to the bottom of the crushing sleeve 20.

[0031] When in use, the broken aerogel block is put into the crushing zone 3 through the opening above the side of the crushing zone 3 and falls to the bottom through the crushing sleeve 20. At this time, the crushing motor 16 is started to drive the crushing blade 22 above to rotate, so that the broken small aerogel block can be crushed to produce finer powder.

[0032] Subsequently, the back-blowing component is activated to blow air from the jet nozzles 19 around the bottom of the crushing sleeve 20 towards the center. This can cool the aerogel to prevent the temperature rise from affecting the finished product, while blowing the crushed aerogel powder upwards. This allows the floating aerogel powder to rise and pass through the filter screen 23 for further upgrading.

[0033] The preferred backflush component is activated intermittently, so that large aerogel powder particles that are not enough to pass through the filter screen 23 will fall down and continue to be crushed. This allows for long-term use without clogging the filter screen 23, and the aerogel powder obtained by airflow sieving is more uniform.

[0034] In this embodiment, the backflush assembly includes an air intake pump 17 and a diverter pipe 18. The plurality of jet nozzles 19 are fixedly connected to the air outlet of the diverter pipe 18. The diverter pipe 18 is fixedly connected to one side of the pulverizing zone 3. The air inlet of the diverter pipe 18 is fixedly connected to the air intake pump 17.

[0035] The intake pump 17 can be connected to an external refrigeration component to introduce low-temperature gas or inert gas through the diverter pipe 18.

[0036] In this embodiment, a flow guide hood 21 is fixedly connected above the filter screen 23, an axial flow fan 4 is fixedly connected above the flow guide hood 21, a cyclone separator 5 is fixedly connected to the air outlet of the axial flow fan 4 through a pipe, a storage tank 6 is fixedly connected below the cyclone separator 5, an exhaust pipe 7 is fixedly connected to the air outlet of the top of the cyclone separator 5, and a filter box 8 is fixedly connected to the air outlet of the exhaust pipe 7.

[0037] The hood 21 can blow the airflow carrying aerogel powder into the cyclone separator 5 through the axial flow fan 4. In this way, the powder in the airflow can be concentrated at the bottom by the cyclone separator 5 and finally fall into the storage tank 6.

[0038] The powder discharged into the exhaust pipe 7 will be filtered and collected through the filter box 8.

[0039] In this embodiment, a temporary storage area 2 is fixedly connected to one side of the crushing zone 3, and a crushing zone 1 is fixedly connected above the temporary storage area 2. Multiple crushing components are rotatably connected to the inner side of the crushing zone 1, and a crushing motor 13 is fixedly connected to the outer side of the crushing zone 1. The power input shaft of the crushing component above is fixedly connected to the power output end of the crushing motor 13.

[0040] The crushing assembly includes a crushing roller 9, a synchronous gear 10, and a synchronous wheel 11. The crushing roller 9 is rotatably connected to the crushing zone 1. The synchronous gear 10 and the synchronous wheel 11 are fixedly connected to one side of the crushing roller 9. The two synchronous gears 10 at the same height mesh with each other. The two synchronous wheels 11 are connected by a synchronous belt 12. One end of the crushing roller 9 is fixedly connected to the power output end of the crushing motor 13.

[0041] The crushing motor 13 can drive the crushing roller 9 at one end to rotate, and then drive the four crushing rollers 9 at the top and bottom to rotate simultaneously through the synchronous gear 10 and synchronous wheel 11. The two sets of crushing rollers 9 can crush large pieces of aerogel into small pieces of aerogel, which is more conducive to subsequent pulverization.

[0042] In this embodiment: When in use, the broken aerogel block is put into the crushing zone 3 through the opening above the side of the crushing zone 3 and falls to the bottom through the crushing sleeve 20. At this time, the crushing motor 16 is started to drive the crushing blade 22 above to rotate, so that the broken small aerogel block can be crushed to produce finer powder.

[0043] Subsequently, the back-blowing component is activated to blow air from the jet nozzles 19 around the bottom of the crushing sleeve 20 towards the center. This can cool the aerogel to prevent the temperature rise from affecting the finished product, while blowing the crushed aerogel powder upwards. This allows the floating aerogel powder to rise and pass through the filter screen 23 for further upgrading.

[0044] The preferred backflush component is started intermittently, so that large aerogel powder particles that are not enough to pass through the filter screen 23 will fall down and continue to be crushed. This allows for long-term use without clogging the filter screen 23, and the aerogel powder obtained by airflow sieving is more uniform.

[0045] The intake pump 17 can be connected to an external refrigeration component to introduce low-temperature gas or inert gas through the diverter pipe 18;

[0046] The hood 21 can blow the airflow carrying aerogel powder into the cyclone separator 5 through the axial flow fan 4. In this way, the powder in the airflow can be concentrated at the bottom by the cyclone separator 5 and finally fall into the storage tank 6.

[0047] The powder discharged into the exhaust pipe 7 will be filtered and collected through the filter box 8;

[0048] The crushing motor 13 can drive the crushing roller 9 at one end to rotate, and then drive the four crushing rollers 9 at the top and bottom to rotate simultaneously through the synchronous gear 10 and synchronous wheel 11. The two sets of crushing rollers 9 can crush large pieces of aerogel into small pieces of aerogel, which is more conducive to subsequent pulverization.

The rotating shaft of the temporary storage baffle 14 is fixedly connected to the power output end of the flip motor 15.

[0052] The flip motor 15 can rotate the temporary storage baffle 14 once every certain period of time, and put the aerogel blocks accumulated at the bottom of the temporary storage area 2 into the crushing area 3 for crushing. This can prevent the aerogel blocks in the temporary storage area from being carried away during the airflow backwash screening, and at the same time, the amount of aerogel crushed each time can be controlled.
