[0021] Embodiment:

[0022] As shown in Figures 1-4 , including drying cylinder 1, the drying cylinder 1 top is connected with feed hopper 11, the drying cylinder 1 side wall is fixedly connected with feed pipe 12, the feed pipe 12 end is fixedly connected with first motor 13, the first motor 13 output end is fixedly connected with first rotating shaft 14, the first rotating shaft 14 side wall is fixedly connected with first auger 15, the feed pipe 12 is connected with discharge hopper 17 away from first motor 13 one end, the discharge hopper 17 is correspondingly arranged with feed hopper 11, the feed pipe 12 is close to the side wall of first motor 13 and is provided with feed inlet 16, the drying cylinder 1 bottom is connected with discharge hopper 18, the drying cylinder 1 middle part is fixedly connected with a pair of support legs 19, the support leg 19 is equipped with buffer assembly, a pair of support legs 19 side wall is fixedly connected with hot air blower 110, the drying cylinder 1 top is installed with air inlet cover 111, the air inlet cover 111 is connected with hot air blower 110 through pipeline, the drying cylinder 1 inside is equipped with conveying assembly.

[0023] The working principle of the above technical scheme is as follows:

[0024] The first motor 13 drives the first rotating shaft 14 and the first auger 15 to rotate, and then the quartz sand is added into the feeding pipe 12 from the feeding port 16. At this time, the material is spirally conveyed to the top in the feeding pipe 12 by the first auger 15, and then falls into the feeding hopper 11 from the discharge hopper 17, and then enters the inside of the drying cylinder 1. Then the hot air enters the air inlet cover 111, and then enters the inside of the drying cylinder 1. When the conveying mechanism conveys the material in the drying cylinder 1 to the lower hopper 18, the material is dried by the hot air. The dried material is discharged from the lower hopper 18. Through the above structure, the feeding pipe 12 is connected with the first motor 13, the first rotating shaft 14 and the first auger 15, which can facilitate uniform feeding of the material during drying, so as to reduce the accumulation and blockage caused by adding too much material at one time, and can form a spiral conveying of the material during conveying, which can reduce the caking between the materials and improve the stability during drying of the material.

[0025] In another embodiment, as shown in Figures 1-3 The conveying assembly comprises a second motor 2, the second motor 2 is fixedly connected to the end of the drying cylinder 1, the output end of the second motor 2 is fixedly connected with a second rotating shaft 21, the second rotating shaft 21 is located in the inside of the drying cylinder 1, and the side wall of the second rotating shaft 21 is fixedly connected with a second auger 22.

[0026] The second motor 2 drives the second rotating shaft 21 and the second auger 22 to rotate. When the material enters the drying cylinder 1, the second auger 22 will continuously stir the material and convey it to the lower hopper 18. When the material is continuously stirred and conveyed in the drying cylinder 1, it will contact with the hot air blown out by the air inlet cover 111, so as to dry the material. Through the above structure, the second motor 2 is connected with the second rotating shaft 21 and the second auger 22, which can make the material stir during conveying, so as to make the material contact with the hot air more uniformly, and improve the uniformity of drying the material.

[0027] In another embodiment, as shown in Figures 3-4 The bottom of the air inlet cover 111 is fixedly connected with a fixed frame 3, the inner side wall of the fixed frame 3 is fixedly connected with two groups of guide plates 31, and the two groups of guide plates 31 are inclined and symmetrically distributed.

[0028] When the air inlet cover 111 blows out hot air, the hot air will pass through the guide plates 31. At this time, the inclined structure of the guide plates 31 to both sides will shunt the hot air to both sides. Through the above structure, the fixed frame 3 and the guide plates 31 can improve the flow range of the hot air blown into the drying cylinder 1 by the air inlet cover 111, so as to improve the contact area of the hot air and the material in the drying cylinder 1, thereby improving the drying effect of the material.

[0029] In another embodiment, as shown in Figure 3As shown, the second rotating shaft 21 is fixedly connected with a scraper 4, and the scraper 4 is in contact with the inner wall of the drying cylinder 1.

[0030] When the second motor 2 drives the second rotating shaft 21 to rotate, the scraper 4 is driven to rotate, and at this time, the scraper 4 is in contact with the inner wall of the drying cylinder 1, so that the inner wall of the drying cylinder 1 can be scraped during rotation. Through the above structure, the scraper 4 is connected with the second rotating shaft 21, so that the inner wall of the drying cylinder 1 can be scraped during conveying of the material, so as to reduce the adhesion of the material to the inner wall of the drying cylinder 1, thereby preventing the material from being left in the drying cylinder 1 and affecting the collection rate of the product.

[0031] In another embodiment, as shown in the figure, Figure 1 The buffer assembly includes a plurality of damping spring shock absorbers 5, which are fixedly connected to the side wall of the drying cylinder 1, and the damping spring shock absorbers 5 are uniformly distributed on the side wall of the drying cylinder 1.

[0032] When the material is conveyed in the drying cylinder 1, the whole drying cylinder 1 will vibrate due to the tumbling of the material, and at this time, the damping spring shock absorbers 5 will continuously contract and rebound to reduce vibration. Through the above structure, the damping spring shock absorbers 5 are connected with the drying cylinder 1 and the supporting legs 19, which can reduce the vibration caused by the conveying of the material, thereby reducing the loosening of the connecting structure caused by vibration, improving the stability and service life of the whole.

[0033] In another embodiment, as shown in the figure, Figure 1 The top of the drying cylinder 1 is fixedly connected with an air extractor 6, and the air extractor 6 is arranged away from the side of the feeding hopper 11.

[0034] When the quartz sand is dried, a large amount of water vapor will be generated, and at this time, the air extractor 6 is started to extract air from the inside of the drying cylinder 1, so that the water vapor can be extracted from the inside of the drying cylinder 1. Through the above structure, the air extractor 6 can reduce the accumulation of water vapor in the drying cylinder 1 during drying, so as to prevent the water vapor from condensing into water droplets and returning to the material, thereby affecting the drying effect of the finished product.

[0035] In another embodiment, as shown in the figure, Figures 2-3 The first auger 15 and the second auger 22 are made of stainless steel.

[0036] The second auger 22 and the first auger 15 are made of stainless steel, which can improve their wear resistance and corrosion resistance, reduce damage caused by friction with the material, and reduce corrosion caused by acidic substances in the material, thereby improving the stability during use.

[0037] The above embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
