[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a drying waste heat recovery device for silicon carbide micropowder, as Figure 1 and Figure 2 shown, which includes a base 1, a drying box 11 provided on the base 1 for drying silicon carbide micropowder, a support column 2 fixedly installed on the base 1, and a tipping mechanism provided on the support column 2 for tipping the drying box 11;

[0028] The tipping mechanism includes a lifting block 3 slidably installed on the support column 2, a tipping rod 7 rotatably installed on the lifting block 3 and having one end fixedly connected to the drying box 11, a second gear 8 fixedly connected to the tipping rod 7, a limiting plate 9 fixedly installed on the base 1, and a rack 10 fixedly installed on the limiting plate 9 and meshing with the second gear 8. One end of the tipping rod 7 is fixedly connected to the outer wall of the drying box 11;

[0029] A lifting mechanism for controlling the lifting of the lifting block 3 is provided on the base 1.

[0030] When in use, the user places the entire device at a suitable position through the base 1. The rising and falling of the lifting block 3 will drive the tipping rod 7 to rise and fall. During the rising and falling process of the tipping rod 7, the second gear 8 fixedly installed on the tipping rod 7 will contact the rack 10 fixedly installed on the limiting plate 9, realizing a 180-degree rotation of the second gear 8. While the second gear 8 rotates, it will drive the tipping rod 7 to rotate 180 degrees, and the rotation of the tipping rod 7 will drive the drying box 11 fixedly installed at one end of the tipping rod 7 to tip.

[0031] Among them, in order to facilitate the lifting of the lifting block 3, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the lifting mechanism includes a limiting rod 4 fixedly installed on the top of the base 1, a first gear 5 fixedly installed on one side of the limiting rod 4, and a rotating belt 6 rotatably installed on the side surface of the first gear 5 and meshing with the first gear 5.

[0032] The output end of an external drive motor drives the first gear 5 to rotate. The rotation of the first gear 5 causes the rotating belt 6 to rotate. The convex blocks fixedly installed on the rotating belt 6 are simultaneously slidably connected in the slots of the lifting block 3. When the rotating belt 6 rotates, the convex blocks will translate and move up and down along with the rotating belt 6. When the convex blocks translate in the slots, the lifting block 3 will remain stationary. When the convex blocks move up and down, the lifting block 3 will be driven to rise and fall.

[0033] Furthermore, in order to facilitate the drying of silicon carbide micropowder, as Figure 2 and Figure 4 shown, an electric heating tube 12 is fixedly connected inside the drying box 11. A first fixing column 13 is fixedly connected to the bottom of the electric heating tube 12. A first spring 14 is sleeved on the side surface of the first fixing column 13. A first baffle 15 is movably connected to the side surface of the first fixing column 13. One end of the first spring 14 is fixedly connected to the bottom of the electric heating tube 12, and the other end of the first spring 14 is fixedly connected to the top of the first baffle 15.

[0034] The electric heating tube 12 heats and dries the silicon carbide micropowder placed inside the drying box 11. After the drying is completed, the drying box 11 will continue to descend. When the first baffle 15 touches the first top column 18, the first baffle 15 will be lifted up. The dried silicon carbide micropowder will flow through the holes at the bottom of the drying box 11 into the inside of the cooling box 16 for cooling. After all the silicon carbide micropowder inside the drying box 11 has flowed out, the drying box 11 will rise. The elastic potential energy of the first spring 14 will push the first baffle 15 back to its initial position to close the drying box 11.

[0035] Even further, in order to facilitate the collection and storage of the cooled silicon carbide micropowder, as Figure 2 and Figure 5 shown, a cooling box 16 is fixedly connected to the top surface of the base 1. A collection box 17 is slidably connected inside the cooling box 16. A first top column 18 is fixedly connected inside the collection box 17. A hot air pipe 19 is fixedly connected to the outer wall of the cooling box 16. The inner cavity of the hot air pipe 19 is communicated with the inner cavity of the cooling box 16.

[0036] When the silicon carbide micropowder is stored in the cooling box 16, the silicon carbide micropowder will be naturally cooled. After the silicon carbide micropowder is cooled, the user pulls out the collection box 17 through the handle, so as to collect and store the cooled silicon carbide micropowder. Then, the collection box 17 is sent into the cooling box 16 through the handle for the next collection and cooling of the silicon carbide micropowder.

[0037] It should be noted that in order to facilitate the recovery of the waste heat during the cooling process of the dried silicon carbide micropowder, as Figure 4 and Figure 5 shown, the top of the support column 2 is fixedly connected with a top cover 26, the top of the limit rod 4 is fixedly connected with the bottom of the top cover 26, the bottom of the top cover 26 is fixedly connected with a feeding box 20, and one end of the hot air pipe 19 far away from the cooling box 16 is fixedly connected to one side of the feeding box 20. The inner cavity of the hot air pipe 19 is communicated with the inner cavity of the feeding box 20.

[0038] During the natural cooling process of the silicon carbide micropowder inside the cooling box 16, the heat dissipated by the cooling of the silicon carbide micropowder will float upward, and the hot air flows into the feeding box 20 through the hot air pipe 19 to preheat the silicon carbide micropowder that has not been dried inside the feeding box 20.

[0039] Furthermore, in order to dry the silicon carbide micropowder preliminarily preheated in the feeding box 20, as Figure 2 and Figure 6 shown, a second top column 21 is fixedly connected inside the feeding box 20. A fixing plate 22 is fixedly connected to the second top column 21. The bottom of the fixing plate 22 is fixedly connected with a second fixing column 23. A second spring 24 is sleeved on the side surface of the second fixing column 23. A second baffle 25 is slidably connected to the outer wall of the second top column 21. The second fixing column 23 penetrates through the second baffle 25.

[0040] When the drying box 11 rises to the top, the two fixing columns 13 installed at the bottom of the electric heating tube 12 will push the second baffle 25 at the bottom of the feeding box 20 upward. At the same time, the second top column 21 will push the first baffle 15 downward. At this time, the silicon carbide micropowder preliminarily preheated inside the feeding box 20 will fall into the drying box 11 for drying. Then, the drying box 11 will descend. Through the action of the first spring 14 and the second spring 24, the first baffle 15 and the second baffle 25 will return to their original positions.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
