[0024] The following is a further description of the present utility model in conjunction with the attached Figures 1-6 figures.
[0025] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a biomass raw material drying device.
[0026] In a specific technical solution, it includes a rotary drum 1, a hole cleaning component 4, and a driving component 11. One end of the rotary drum 1 is provided with a discharge housing 2, and a material deflecting plate is arranged inside the rotary drum 1. When the rotary drum 1 rotates, it can scoop up the material and sprinkle it down, improving the drying uniformity of the material. A discharge port is arranged below the discharge housing 2. One side of the discharge housing 2 is connected to a hot air system, and hot air is introduced into the rotary drum 1 to dry the material. An intercepting net 3 is rotatably installed inside the discharge housing 2. One end of the rotary drum 1 is fixedly connected to one side of the intercepting net 3 through a connecting frame. The intercepting net 3 is used to limit the position and range where the material falls out, enabling the material to be accurately discharged to the discharge port. An arc-shaped limiting chute 5 is opened on the outside of the discharge housing 2, and a pick-up hole 6 is opened inside the arc-shaped limiting chute 5. The hole cleaning component 4 can be quickly picked up and placed through the pick-up hole 6. Two threaded grooves 7 are opened inside the arc-shaped limiting chute 5. An anti-detachment block 8 slides inside the arc-shaped limiting chute 5. Two positioning studs 9 are threadedly connected inside the anti-detachment block 8. As Figure 5 shown, the two threaded grooves 7 are arranged one above the other, and the two positioning studs 9 are also arranged one above the other. When the positioning stud 9 below the anti-detachment block 8 corresponds to the threaded groove 7 below, the pick-up hole 6 is blocked. On the contrary, when the positioning stud 9 above the anti-detachment block 8 corresponds to the threaded groove 7 above, the pick-up hole 6 is exposed. One end of the rotary drum 1 is provided with a feed hopper 10, and a waste outlet is arranged in the feed hopper 10. The connections between the discharge housing 2, the feed hopper 10, and the rotary drum 1 are all rotatable connections, and the rotary drum 1, the discharge housing 2, and the feed hopper 10 all have a certain inclination to facilitate the material to enter the discharge housing 2.
[0027] The hole cleaning component 4 is arranged inside the discharge housing 2. The hole cleaning component 4 is used to clear the material stuck in the mesh holes of the intercepting net 3, preventing the mesh holes of the intercepting net 3 from being blocked by the stuck material and affecting the efficiency of hot air entry. The hole cleaning component 4 includes a mounting strip 41 and a support housing 42. The support housing 42 is fixed to the inner surface of the discharge housing 2, and one end of the support housing 42 corresponds to the pick-up hole 6. The mounting strip 41 is clamped inside the support housing 42. A plurality of mounting grooves 43 are opened inside the mounting strip 41. A material ejecting needle 44 slides inside each of the plurality of mounting grooves 43. Springs 45 are arranged inside each of the plurality of mounting grooves 43. The springs 45 play a role in pushing the material ejecting needles 44 towards the mesh holes of the intercepting net 3. One end of the material ejecting needle 44 is relatively thin and round, and can be pushed into the mesh hole to push the material in the mesh hole outwards.
[0028] On one side of each of the multiple mounting grooves 43, a perforation 46 is provided. On the inner side of each of the multiple perforations 46, a limiting groove 47 is provided. On one side of each of the multiple ejector pins 44, a threaded hole 48 is provided. A screw rod 49 is threadedly connected inside each of the multiple threaded holes 48. The sizes of the screw rod 49 and the threaded hole 48 are adapted to each other. One end of the screw rod 49 screwed into the threaded hole 48 can mount the screw rod 49 on the ejector pin 44. A spring 45 is sleeved outside the screw rod 49. A baffle 410 is sleeved outside the screw rod 49. The threaded connection between the screw rod 49 and the ejector pin 44 enables the baffle 410 to be removed from one side of the mounting strip 41. By quickly disassembling and assembling the screw rod 49, the spring 45 can be quickly replaced.
[0029] Among them, the driving assembly 11 is arranged outside the rotating drum 1. The driving assembly 11 is used to drive the rotating drum 1 to rotate and turn over the materials, repeatedly turning over the piled-up materials to achieve the effect of uniform drying and accelerating the drying efficiency. The driving assembly 11 includes a toothed ring 111, a gear 112, and a driving motor 113. The toothed ring 111 is fixed outside the rotating drum 1. The gear 112 is fixed at one end of the output shaft of the driving motor 113. The gear 112 meshes with the toothed ring 111. By driving the gear 112 to rotate through the driving motor 113, the gear 112 drives the toothed ring 111 to rotate at a reduced speed through the meshing teeth, and the toothed ring 111 drives the rotating drum 1 to slowly rotate to turn over the materials.
[0030] For those skilled in the art to fully understand the technical solution, the following is an overall overview of this application:
[0031] During use, the materials are fed into the rotating drum 1 through the feed hopper 10. The driving motor 113 drives the gear 112 to rotate. The gear 112 drives the rotating drum 1 to slowly rotate to turn over the materials through the meshing toothed ring 111. The hot air system introduces hot air into the rotating drum 1 from one side of the discharge housing 2 to dry the materials. In the inclined rotating drum 1, the dried materials enter the discharge housing 2 along the inclined direction for discharging. When the materials move into the interior of the discharge housing 2, some materials will get stuck in the mesh holes of the intercepting net 3 when sliding and rolling. Since the rotating drum 1 continuously drives the intercepting net 3 to rotate during rotation, the intercepting net 3 will continuously pass by the ejector pins 44 on the mounting strip 41. After being pushed by the intercepting net 3, the ejector pins 44 squeeze the spring 45 and push the screw rod 49 out of the mounting groove 43. The baffle 410 is fixed in the limiting groove 47 and remains stationary under the limitation of the shape inside the support housing 42. Under the reaction force of the spring 45, when the mesh holes of the intercepting net 3 correspond to the ejector pins 44, the ejector pins 44 are pushed into the mesh holes to eject the materials stuck in the mesh holes. The materials will fall into the discharge port for discharging, preventing the mesh holes of the intercepting net 3 from being blocked by the raw materials, ensuring that the hot air can smoothly enter the rotating drum 1 while avoiding raw material loss, helping to improve the drying efficiency and reduce energy consumption.
[0032] After long-term use, the spring 45 will experience a certain degree of failure fatigue, which will affect the material cleaning effect of the ejector pin 44. The spring 45 can be replaced regularly to maintain the quality and effect of the material cleaning of the ejector pin 44. Just unscrew the positioning stud 9 from the threaded groove 7, slide the anti-detachment block 8 upward along the arc-shaped limit chute 5, and screw the upper positioning stud 9 into the corresponding threaded groove 7 to expose the mounting strip 41. Then directly pull out the mounting strip 41, unscrew the screw rod 49 from the screw hole 48 and pull it out of the mounting groove 43. After pouring out the spring 45, put a new spring 45 on the screw rod 49 and place it in the mounting groove 43, and screw one end of the screw rod 49 into the screw hole 48. When the baffle 410 is stuck in the limit groove 47, the replacement of the spring 45 is completed. The baffle 410 being stuck in the limit groove 47 can prevent the spring 45 from detaching from the mounting groove 43. After replacement, insert the mounting strip 41 into the support shell 42, and then move the anti-detachment block 8 back to its original position for positioning.
