[0002] Biomass fuel refers to agricultural waste materials such as straw, sawdust and rice husks. They are highly polluting materials if used directly for combustion. After processing, they can be formed into clean fuel for combustion. After rolling, crushing and forming, biomass fuel can be made into granules, which is convenient for transportation and storage, and greatly enhances the combustion performance of biomass fuel.

[0003] Biomass pellet fuel is generally processed using drum drying equipment, but the existing drum drying equipment mainly drives the drum to rotate outside the supporting device through the meshing of the gears with the transmission device on the outside of the drum. There is no direct connection between the transmission device and the drum, only the meshing contact between the gears. The drum is very easily affected by external forces during rotation and deflected and misplaced outside the supporting device, affecting the normal transmission of the drum, which is very inconvenient. Therefore, a biomass pellet fuel drying device that can position the drum is designed. Utility Model Content

[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] See also Figure 1-4 The biomass pellet fuel drying device of the utility model comprises a drum 1, a bottom beam 2 and a slip ring 101 arranged on the outside of the drum 1. The outside of the bottom beam 2 is provided with transmission components that are symmetrically distributed to support the slip ring 101 on the outside of the drum 1. Rotationally adjustable positioning parts are arranged on the outside of the two transmission components. The two positioning parts are assembled to form a ring to limit the transmission of the slip ring 101.

[0024] See also Figure 4 The slip rings 101 are symmetrically installed at both ends of the drum 1, and a gear ring 102 is installed in the center of the outer side of the drum 1.

[0025] See also Figure 4 In order to perform basic positioning of the drum 1, the transmission assembly is composed of a support seat 201 and a first transmission wheel 202. There are two bottom beams 2, which are located on the outside of the slip ring 101 and correspond to their positions. The support seat 201 is symmetrically distributed with the center of the drum 1 as the origin and is installed on the side of the bottom beam 2 close to the drum 1. The first transmission wheel 202 is installed between the two sides of the inner wall of the support seat 201. The two adjacent first transmission wheels 202 can be designed with outer grooves and spacing distances. When the drum 1 is installed, the drum 1 can be initially positioned between the grooves by the two first transmission wheels 202 through the slip ring 101. The drum 1 can also perform normal transmission contact with the first transmission wheel 202, which does not affect the subsequent secondary fixation of the semicircular ring 3. The inner wall of the outer groove of the first transmission wheel 202 fits the surface of the slip ring 101.

[0026] See also Figure 2In order to make the drum 1 still have the characteristic of easy installation, the positioning member is composed of a semicircular ring 3, a second transmission wheel 4, a movable rod 5 and a threaded sleeve 6. The semicircular ring 3 is symmetrically installed on the outside of the support seat 201 with the center of the drum 1 as the origin. One end of the semicircular ring 3 is rotatably connected to the support seat 201, and one end of the two adjacent semicircular rings 3 close to each other is provided with a docking groove 302 symmetrically distributed with the center of the semicircular ring 3 as the origin. One end of the movable rod 5 is installed between the two sides of the inner wall of the docking groove 302, and the other end of the movable rod 5 is provided with a thread. The movable rod 5 is rotatably connected between the two sides of the inner wall of the docking groove 302. The size, pitch and direction of the outer side threads of the two adjacent movable rods 5 are the same, and the threads at both ends can form the same section of thread. The threaded sleeve 6 is threadedly connected to the outer sides of the two adjacent movable rods 5. When the connection relationship between the two movable rods 5 is cancelled, the threaded sleeve 6 can be completely moved to the outer side of the other movable rod 5 for storage by rotating the threaded sleeve 6.

[0027] See also Figure 1 In order to cooperate with the first transmission wheel 202 to position the drum 1, a notch 301 is penetrated and opened at one end of the surface of the semicircular ring 3 away from the bottom beam 2, and the second transmission wheel 4 is installed between the two sides of the inner wall of the notch 301 close to each other, and the inner wall of the outer groove of the second transmission wheel 4 is in contact with the surface of the slip ring 101. The two second transmission wheels 4 cooperate with the two first transmission wheels 202 to form a rectangular distribution, and the drum 1 and the outer slip ring 101 can be positioned by cooperating with the first transmission wheel 202 through the outer groove.

[0028] When it is necessary to fix the drum 1, first align the slip rings 101 at both ends of the drum 1 with the first transmission wheels 202 of the outer support seats 201 of the two bottom beams 2, and place the slip ring 101 in the grooves on the outer sides of the two adjacent first transmission wheels 202, so that the first transmission wheels 202 preliminarily position the slip ring 101 and the drum 1 through the grooves, and then rotate the semicircular ring 3 on the outer side of the first support seat 201 so that the second transmission wheels 4 in the outer notches 301 of the two adjacent semicircular rings 3 are directly buckled on the outer side of the slip ring 101 through the grooves. At this time, the docking grooves 302 at the other ends of the two semicircular rings 3 are opposite, rotate the movable rods 5 in the two adjacent docking grooves 302 so that the two movable rods 5 are on the same horizontal line, and then rotate the threaded sleeve 6 on the outer side of one of the movable rods 5 and threadedly connect it with the adjacent movable rod 5. At this time, the two semicircular rings 3 cooperate to fix the drum 1.
