Description

Technical Field

[0001] The present application relates to the field of drying technology, and more specifically, to a biomass bulk forced drying device. Background Art

[0002] Bulk biomass refers to fuel bulk materials composed of various plant and animal cellulose, including hemp stalks, peanut shells, rice husks, sawdust, etc. It is a typical renewable energy source. During the production of bulk biomass, since the raw materials contain moisture, dryers are often used to dry them to increase the dryness of the bulk biomass. The dried bulk biomass can effectively improve the combustion effect.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] Example:

[0033] See also Figures 1 to 5 , this application embodiment discloses a biomass bulk forced drying device, please refer to Figure 3 and Figure 5, comprising a drying box 1, the top and side surfaces of the drying box 1 are respectively provided with a feed pipe and a discharge door 3, a drying mechanism 2 is provided inside the drying box 1, a movable plate 10 is provided inside the drying box 1, and a plurality of limit assemblies are provided on the movable plate 10, a collision mechanism is provided below the movable plate 10 inside the drying box 1, and a scattering mechanism is further provided above the movable plate 10 inside the drying box 1, and the movable plate 10 is inclined;

[0034] The collision mechanism includes a stepper motor 4 mounted on the outer wall of the drying box 1. An active rod 6 is mounted on the output end of the stepper motor 4. A plurality of rotating blocks 14 are provided on the outer periphery of the active rod 6. The rotating blocks 14 are elliptical blocks, and the long radius directions of the plurality of rotating blocks 14 are staggered. The stepper motor 4 is driven to rotate the active rod 6 and the rotating blocks 14. Since the rotating blocks 14 rotate in different directions, they can collide with the bottom surface of the movable plate 10 in sequence after rotation, thereby causing the movable plate 10 to vibrate continuously, the bulk material vibrates, and the bulk material at the bottom can rise to the top;

[0035] The breaking up mechanism includes a driven rod 9, which is rotatably connected between the inner walls of the drying box 1, and a transmission assembly is provided between the driven rod 9 and the active rod 6, and a plurality of blades 15 are fixed to the outer periphery of the driven rod 9. As the movable plate 10 is tilted and the bulk material vibrates, the bulk material will move to the lowest point of the movable plate 10, and the driven rod 9 rotates as the active rod 6 rotates, driving the blades 15 to stir and break up the bulk material, thereby fully dispersing the bulk material. Part of the bulk material will also be dispersed to the high point of the movable plate 10 and vibrate and fall again, which is conducive to the uniformity of the drying degree of the bulk material.

[0036] Please refer to Figure 1 and Figure 3 The drying mechanism 2 includes a hot air blower 200 installed on the top surface of the drying box 1. The output end of the hot air blower 200 is connected to an air supply pipe 201, which runs through the drying box 1. The air supply pipe 201 is sealed and fixedly connected to the drying box 1. The air supply pipe 201 is connected to a plurality of nozzles 202, and the nozzles 202 are located inside the drying box 1. Hot air is blown out by the hot air blower 200 to dry the bulk material. The nozzles 202 are directed toward the high point of the movable plate 10 and can blow the scattered bulk material toward the high point of the movable plate 10. A plurality of pipe clamps 203 are fixed to the inner wall of the drying box 1, and the air supply pipe 201 is arranged in the pipe clamp 203. The pipe clamp 203 is used to limit the air supply pipe 201.

[0037] Please refer to Figure 3 and Figure 4The limit assembly includes two fixed blocks 12 fixed to the inner wall of the drying box 1, and a mounting rod 11 is fixedly connected between the two fixed blocks 12, the mounting rod 11 is slidably connected to the movable plate 10, and a return spring 13 is also arranged on the outer periphery of the mounting rod 11. The top of the return spring 13 is fixed to the bottom surface of the movable plate 10, and the bottom end of the return spring 13 is fixed to the top surface of the fixed block 12. When the movable plate 10 is collided with the rotating block 14, the movable plate 10 can be lifted and lowered on the mounting rod 11, and the return spring 13 can reset the movable plate 10, so that the movable plate 10 can be lifted and lowered. A mounting groove 16 is provided on the side of the movable plate 10, and a roller 17 is rotatably connected in the mounting groove 16. The roller 17 contacts the inner wall of the drying box 1, and the roller 17 rolls with the inner wall of the drying box 1, which not only plays a role in limiting the lifting and lowering of the movable plate 10, but also reduces the wear between the movable plate 10 and the drying box 1.

[0038] Please refer to Figure 2 The transmission assembly includes a driving wheel 5, an active rod 6 and a driven rod 9, all of which pass through and are rotatably connected to the drying box 1. The driving wheel 5 is fixedly installed on the end of the active rod 6 outside the drying box 1, and the driven rod 9 is fixedly connected to the driven wheel 8 on the end outside the drying box 1. A belt 7 is provided between the driving wheel 5 and the driven wheel 8. The driving wheel 5, the driven wheel 8 and the belt 7 are arranged on the rear end face of the drying box 1 for easy maintenance.

[0039] The implementation principle of this embodiment is as follows: the biomass bulk material is put into the drying box 1 by manpower or a feeding mechanism, and then the hot air blower 200 and the stepper motor 4 are driven. The hot air blower 200 can make the nozzle 202 spray hot air to dry the bulk material, and the bulk material will fall onto the movable plate 10. The stepper motor 4 drives the active rod 6 and a plurality of rotating blocks 14 to rotate. The rotating blocks 14 will collide with the movable plate 10 when they rotate, and because the directions of the rotating blocks 14 are different, they can collide with the bottom surface of the movable plate 10 in sequence after rotation. Collision, and because a reset spring 13 is provided at the bottom of the movable plate 10, the movable plate 10 will be restricted by the reset spring 13 after being collided and risen by the rotating block 14, and the movable plate 10 will vibrate continuously, and the bulk material will be vibrated, and the bulk material at the bottom can rise to the top, and the bulk material will gradually move to the lowest point of the movable plate 10 with the movable plate 10, and the active rod 6 drives the driven rod 9 to rotate, thereby driving the blade 15 to rotate and stir the bulk material, so that the bulk material is fully dispersed, which is conducive to uniform drying of the bulk material.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
