[0002] At present, due to the structural characteristics of aerogel itself, aerogel coatings can effectively reduce heat transfer, play a role in improving the environment and reducing energy consumption. The nanopores and three-dimensional network structure of aerogel disrupt the heat conduction path of the matrix. The unique nanopore structure restricts the free flow of air molecules, inhibits the convective heat transfer of air, and the infinite number of pore walls form reflecting and refracting surfaces for thermal radiation, maximizing the inhibition of radiative heat conduction. Therefore, using aerogel with excellent heat insulation performance in coatings will greatly improve the heat insulation effect.
[0003] In related technologies, when producing aerogel thermal insulation coatings, a mixer is needed to grind and stir the raw materials. However, often only the stirring shaft is used to stir the raw materials in the equipment. The distance between the stirring shaft and the inner wall of the equipment is relatively far. During mixing, the stirring is not uniform enough, the grinding effect is poor, and the stirring efficiency is low. Therefore, it needs to be improved. Summary of the Utility Model
[0004] In order to make the stirring more uniform, enhance the stirring and grinding effect, and improve the processing efficiency, the present application provides a mixer for producing aerogel thermal insulation coatings.
[0005] A mixer for producing aerogel thermal insulation coatings provided by the present application adopts the following technical scheme:
[0006] A mixer for producing aerogel thermal insulation coatings includes a cylindrical machine shell. A stirring motor is provided at the top of the machine shell. The driving shaft of the stirring motor is connected to a rotating shaft. The rotating shaft is vertically located inside the machine shell. A plurality of stirring rods are provided on the side wall of the rotating shaft. A group of connecting rods are symmetrically provided on the side wall of the rotating shaft. A grinding rod is rotatably provided below the connecting rod. A side grinding assembly is provided between the grinding rod and the inner wall of the machine shell.

A grinding disc is slidably provided at the bottom end of the grinding rod. A bottom grinding assembly is provided between the grinding disc and the inner wall of the machine shell. The bottom grinding assembly is used to drive the grinding disc to reciprocally slide at the bottom end of the grinding rod when the rotating shaft rotates.
[0007] Preferably, the side grinding assembly includes a connecting shaft, a gear and a rack. The connecting shaft is fixedly provided at the top end of the grinding rod. The connecting shaft is rotatably connected to the connecting rod. The gear is provided on the connecting shaft. The rack is fixedly provided on the inner wall of the machine shell. The length direction of the rack is arranged along the circumferential direction of the machine shell. The gear and the rack are meshed with each other.
[0008] Preferably, a plurality of grinding blocks are provided on the side wall of the grinding rod, and the grinding rod is provided with a hollow interior.
[0009] Preferably, the bottom grinding assembly includes a linkage rod and a linkage block. A plurality of the linkage rods are symmetrically and fixedly provided on the grinding disc. A linkage groove is provided on the side wall of the grinding rod and at the bottom end. The linkage rod is slidably and rotatably connected to the linkage groove.

[0011] In summary, the present application includes at least one of the following beneficial technical effects:
[0012] 1. By providing a stirring motor, a rotating shaft, a grinding rod, a stirring rod, a grinding rod, a grinding block, a connecting shaft, a gear and a rack, when the stirring motor drives the rotating shaft to rotate, the rotating shaft drives the connecting rod to rotate, the connecting rod drives the connecting shaft to rotate, and the gear on the connecting shaft abuts against the rack. When the connecting shaft rotates following the connecting rod, it also rotates itself. The connecting shaft then drives the grinding rod to rotate. The raw materials between the grinding rod and the inner side wall of the machine shell will be continuously squeezed as the grinding rod rotates. While the grinding rod continuously moves in the machine shell, it rotates and squeezes the raw materials, so that the grinding rod can play a grinding role, effectively improving the mixing effect and achieving low cost at the same time;
[0013] 2. By providing a grinding disc, a linkage rod, a linkage block, a linkage groove and a corrugated groove, when the stirring motor drives the rotating shaft to rotate, the rotating shaft drives the grinding rod to slide in the machine shell. When the grinding rod slides, it drives the grinding disc to slide. At the same time, the linkage block slides in the corrugated groove. Since the length of the corrugated groove is arranged in a wave shape, when the linkage block slides in the corrugated groove, it drives the linkage rod to reciprocally lift in the linkage groove. The reciprocating lifting of the linkage rod drives the grinding disc to reciprocally lift. When the grinding disc reciprocates, it can squeeze and grind the raw materials with a higher concentration at the bottom of the machine shell, further improving the mixing and grinding effect. At the same time, it is controlled only by one stirring motor, saving the production cost of the equipment. Description of the Drawings

Detailed implementation mode
[0017] The following will further elaborate on this application in conjunction with the attached Figure 1-2 drawings.
[0018] An embodiment of this application discloses a mixer for the production of aerogel thermal insulation coatings. Referring to Figure 1 , it includes a cylindrical machine housing 1. Raw materials can be transported into the machine housing 1 through a screw conveyor from the feeding port at the top of the machine housing 1. A stirring motor 2 is arranged at the top of the machine housing 1. The driving shaft of the stirring motor 2 is connected with a rotating shaft 21. The length direction of the rotating shaft 21 is arranged vertically and extends into the machine housing 1. A plurality of stirring rods 22 are arranged on the side wall of the rotating shaft 21. The length direction of the stirring rods 22 is arranged horizontally. After different raw materials are transported into the machine housing 1 through the screw conveyor, the stirring motor 2 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives a plurality of stirring rods 22 to stir the raw materials in the machine housing 1.
[0019] Referring to Figure 1 , a grinding rod 31 is rotatably arranged below the connecting rod 3. The length direction of the grinding rod 31 is arranged vertically, and the grinding rod 31 is close to the inner side wall of the machine housing 1. A plurality of grinding blocks 33 are integrally formed on the side wall of the grinding rod 31, and the inside of the grinding rod 31 is hollow. A side grinding assembly 4 is arranged between the grinding rod 31 and the inner wall of the machine housing 1. The side grinding assembly 4 includes a connecting shaft 41, a gear 42 and a rack 43. The connecting shaft 41 is fixedly arranged at the top of the grinding rod 31. The connecting shaft 41 and the grinding rod 31 are coaxially arranged. The connecting shaft 41 and the connecting rod 3 are rotatably connected. The gear 42 is fixedly arranged on the connecting shaft 41. The gear 42 and the connecting shaft 41 are coaxially arranged. The rack 43 is fixedly arranged on the inner wall of the machine housing 1. The length direction of the rack 43 is arranged along the circumferential direction of the machine housing 1. The gear 42 and the rack 43 are meshed with each other. When the stirring motor 2 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the connecting rod 3 to rotate, the connecting rod 3 drives the connecting shaft 41 to rotate, and the gear 42 on the connecting shaft 41 abuts against the rack 43. When the connecting shaft 41 rotates with the connecting rod 3, it also rotates itself. The connecting shaft 41 then drives the grinding rod 31 to rotate. The raw materials between the grinding rod 31 and the inner side wall of the machine housing 1 will be continuously squeezed as the grinding rod 31 rotates. While the grinding rod 31 moves continuously in the machine housing 1 and rotates to squeeze the raw materials, the grinding rod 31 can play a grinding role, effectively improving the mixing effect and achieving low cost at the same time.
[0020] Referring toFigure 1 At the bottom end of the grinding rod 31, a grinding disc 32 is provided. A bottom grinding assembly 5 is provided between the grinding disc 32 and the inner wall of the casing 1. The bottom grinding assembly 5 includes a linkage rod 51 and a linkage block 52. A plurality of linkage rods 51 are symmetrically and fixedly arranged on the grinding disc 32. A linkage groove 311 is formed in the side wall of the grinding rod 31 and at the bottom end. The length direction of the linkage groove 311 is arranged along the circumferential direction of the grinding rod 31. The linkage rod 51 is slidably and rotatably connected to the linkage groove 311. The linkage block 52 is fixedly arranged on one of the linkage rods 51. A corrugated groove 6 is formed in the inner side wall of the casing 1. The linkage block 52 is slidably arranged in the corrugated groove 6. When the stirring motor 2 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the grinding rod 31 to slide in the casing 1. When the grinding rod 31 slides, it drives the grinding disc 32 to slide. At the same time, the linkage block 52 slides in the corrugated groove 6. Since the length of the corrugated groove 6 is arranged in a wave shape, when the linkage block 52 slides in the corrugated groove 6, it drives the linkage rod 51 to reciprocally lift in the linkage groove 311. The lifting of the linkage rod 51 drives the grinding disc 32 to reciprocally lift. When the grinding disc 32 reciprocates, it can extrude and grind the raw materials with a higher concentration at the bottom inside the casing 1, further improving the mixing and grinding effect. At the same time, it is only controlled by one stirring motor 2, saving the production cost of the equipment.
[0021] Refer to Figure 1 and Figure 2 , a plurality of guide vanes 7 are connected to the bottom end of the rotating shaft 21. The guide vanes 7 are bent. The guide vanes 7 are in mutual contact with the bottom wall of the casing 1. When the rotating shaft 21 rotates, the guide vanes 7 can divert the raw materials at the bottom of the casing 1. The raw materials are continuously conveyed towards the bottom end direction of the grinding disc 32 through the guide vanes 7, which is beneficial to the repeated extrusion and grinding work of the grinding disc 32.
[0022] The implementation principle of a mixer for producing aerogel thermal insulation coatings in an embodiment of the present application is as follows: When the equipment is working, the stirring motor 2 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives a plurality of stirring rods 22 to stir the raw materials in the casing 1; at the same time, the rotating shaft 21 drives the connecting rod 3 to rotate, the connecting rod 3 drives the connecting shaft 41 to rotate, and the gear 42 on the connecting shaft 41 abuts against the rack 43, and the connecting shaft 41 further drives the grinding rod 31 to rotate. While the grinding rod 31 continuously moves in the casing 1, it rotates and squeezes the raw materials between the inner side wall of the casing 1; at the same time, when the stirring motor 2 drives the grinding rod 31 to slide in the casing 1, the grinding rod 31 drives the grinding disc 32 to slide when it slides, and at the same time, the linkage block 52 slides in the waveform groove 6, driving the linkage rod 51 to reciprocate up and down in the linkage groove 311. The reciprocating movement of the linkage rod 51 drives the grinding disc 32 to reciprocate up and down. When the grinding disc 32 reciprocates, it can squeeze and grind the raw materials with a higher concentration at the bottom of the casing 1; by controlling the rotation of the rotating shaft 21 through the stirring motor 2, the stirring rod 22 stirs the raw materials away, the grinding rod 31 rotates and squeezes and grinds the raw materials between the inner wall of the casing 1, and the grinding disc 32 rotates and squeezes and grinds the raw materials between the bottom wall of the casing 1, making the stirring more uniform, enhancing the stirring and grinding effect, and improving the production and processing efficiency of the aerogel thermal insulation coating.
[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
