DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 3As shown, the utility model is a single-channel drying system for drying wood shavings. Specifically, it includes a drying drum 1 for drying wood shavings. The drying drum 1 is a hollow drum arranged horizontally. Further, a circular rail 11 and a circular ring gear 12 are coaxially arranged on the cylindrical surface of the drying drum 1. The drying drum 1 is rotatably connected to the support leg 2. There are two circular rails 11. The two circular rails 11 are coaxially arranged at the two ends of the cylindrical surface of the drying drum 1, and the two circular rails 11 are rotatably connected to the support leg 2. The circular gear 12 is transmission-connected to the drive motor 4 and driven by the drive motor 4. The driving motor 4 drives the rotation; when the single-channel drying system is performing the drying operation, first, the end port of the drying drum 1 close to the driving motor 4 is connected to the feeding device, and the feeding device adds the wood shavings to the drying drum 1, and then the drying drum 1 rotates and flips the wood shavings. At the same time, the end port of the drying drum 1 close to the driving motor 4 is connected to the hot air source. Generally, a device for filtering the hot air is also provided between the drying drum 1 and the hot air source to ensure the quality of the hot air. Finally, the dried wood shavings are unloaded from the end port of the drying drum 1 away from the driving motor 4, completing the entire drying process.

[0029] Further optimized, the utility model also includes a plurality of scraper assemblies 5 evenly arranged on the inner wall of the drying drum 1, the scraper assembly 5 includes a first scraper 51 fixedly arranged on the inner wall of the drying drum 1, and a second scraper 52 rotatably connected to the first scraper 51 at one end away from the inner wall of the drying drum 1, and a connecting rod 53 is fixedly provided on the end of the second scraper 52 away from the inner wall of the drying drum 1. The second scraper 52 is driven to rotate around the first scraper 51 by adjusting the connecting rod 53, thereby changing the angle of scraping the wood shavings. The scraping force of the second scraper 52 at different angles is different. At the same time, the second scraper 52 can be adjusted to a suitable angle so that the second scraper 52 can grab the wood shavings and rotate with the drying drum 1. After the wood shavings grabbed by the second scraper 52 rotate to the top, the wood shavings will slide and fall due to the change in the spatial angle of the second scraper 52.

[0030] Further optimization, such as Figure 1 and Figure 3 As shown, a connecting support plate 3 is provided between the supporting legs 2, and the drive motor 4 is fixedly mounted on the connecting support plate 3. The connecting support plate 3 is mainly used for workers to stand on it for repair or maintenance. Furthermore, the connecting support plate 3 is provided with a ladder 8 connected to the bottom surface, and the ladder 8 is used to facilitate workers to go up and perform repair work.

[0031] In order to realize automatic adjustment of the angle of the second scraper 52, it is further optimized as follows: Figure 2 、 Figure 4 and Figure 5As shown, the present invention also includes an angle adjustment mechanism 6 arranged in an end of the drying drum 1, and the angle adjustment mechanism 6 is connected to the connecting rod 53. Specifically, the angle adjustment mechanism 6 includes a fixed ring base 61 fixed in an end of the drying drum 1, a swivel rack 62 rotatably installed in the fixed ring base 61, and the swivel rack 62 is meshed and transmission-connected with an adjusting motor 63 installed on the fixed ring base 61. The inner end of the swivel rack 62 is fixed to form an adjusting claw body 64 corresponding to the connecting rod 53, and the adjusting claw body 64 forms an oblong hole. The end of the connecting rod 53 is movably connected to the oblong hole. Preferably, the oblong hole is slidably connected to the end of the connecting rod 53. When the swivel rack 62 rotates and drives the adjusting claw body 64 to rotate together, the adjusting claw body 64 rotated to a different position will toggle the connecting rod 53 to drive the second scraper 52 to adjust the angle, so that the angle of the second scraper 52 can be automatically adjusted by controlling the adjusting motor 63 of the angle adjustment mechanism 6.

[0032] When the second scraper 52 grabs the wood shavings and moves to the upper part of the drying drum 1, the wood shavings will slide down from the second scraper 52 and slide to the lower part of the drying drum 1. Although the wood shavings will contact the hot air flow in the drying drum 1 when sliding, which helps to improve the drying efficiency, the dispersion effect of the sliding wood shavings is usually not good, and there is no way to make the wood shavings more fully contact with the hot air flow. Therefore, further optimization, such as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the present invention further includes a dispersion device 7 provided in the drying drum 1, and the dispersion device 7 is used to disperse the wood shavings that slide down. Specifically, the dispersion device 7 includes a mounting rod 71 rotatably mounted in the drying drum 1. Further, the mounting rod 71 is integrally formed with a plurality of evenly arranged mounting bases 72. The mounting bases 72 are used to set a dispersion cone, and the top of the dispersion cone is facing upwards to face the wood shavings that slide down. Specifically, the dispersion cone of the present invention is set in two directions, such as Figure 6 and Figure 7 As shown, the top surface of the mounting base 72 forms first-direction dispersion cones 73 arranged at intervals, and second-direction dispersion cones 74 are formed in the gaps between the first-direction dispersion cones 73. The length directions of the first-direction dispersion cones 73 and the second-direction dispersion cones 74 are perpendicular to each other, and the position of the second-direction dispersion cone 74 is higher than that of the first-direction dispersion cone 73, so that the sliding wood particles are first dispersed by the second-direction dispersion cone 74, and then dispersed for the second time by the second-direction dispersion cone 74, so that the dispersion efficiency is higher, and the dispersed wood particles are more fully in contact with the hot air flow, thereby improving the drying efficiency.

[0033] In the dispersion device 7, it is necessary to always keep the dispersion cone facing upward, that is, the dispersion device 7 will not rotate with the rotation of the drying drum 1. For further optimization, downward balancing hangers 75 are formed at both ends of the mounting base 72. Preferably, the balancing hangers 75 are cone-shaped pendants, which have a pulling force that maintains a vertical downward direction. The function of the balancing hangers 75 is to generate a force downward. The two balancing hangers 75 form a group of balancing levers centered on the axis of the mounting rotating rod 71, so that the dispersion device 7 always keeps the first direction dispersion cone 73 and the second direction dispersion cone 74 facing upward, further allowing the sliding wood chips to be dispersed by the cone tops of the first direction dispersion cone 73 and the second direction dispersion cone 74, resulting in better effect.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
