Description

Technical Field

[0001] The utility model relates to the technical field of biochar production, and particularly relates to a drying device for biochar production. Background Art

[0002] The main raw material sources of biochar include forestry and agricultural and forestry residues, urban biomass waste, etc. During the production process, the raw materials need to be dried and pretreated, and then biochar products can be obtained by high-temperature pyrolysis in a carbonization device. The drying device plays a key role in the biochar production process, which is used to evaporate the excess moisture, thereby increasing the calorific value of the biomass material and reducing the energy loss during the pyrolysis process. The drying device controls parameters such as temperature, humidity, and wind speed in the channel to achieve rapid and uniform drying of the biomass material, thereby improving production efficiency. Since there will be material debris and particles attached to the surface during the biochar production and processing, it is necessary to perform a drying and removal operation on the debris and particles.

[0003] In the related art, during the use of the drying device, generally, a mesh conveyor belt is used to convey the material into the drying chamber for drying. As the mesh conveyor belt moves and cooperates with the drying chamber, the dried material is taken out of the drying chamber for use.

[0004] However, during the use of the current drying device, when the mesh conveyor belt is working, the debris and particles attached to the surface of the biochar will be embedded into the mesh holes of the conveyor belt, resulting in difficulty in achieving a uniform air permeability effect during the later work of the conveyor belt, affecting the drying air permeability uniformity and drying effect during the drying and conveying process.

Detailed implementation manner

[0030] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0031] Refer to Figures 1 - 4 , the present utility model provides a technical solution: a drying equipment for biochar production, including a support frame 1 and a drying and cleaning mechanism. The drying equipment body 2 is installed on the top of the support frame 1. The bottom inside the drying equipment body 2 is installed with a conveyor belt 3. When the conveyor belt 3 is used in cooperation with the drying equipment body 2, it can brush and clean the residual and embedded material particle debris on the surface of the conveyor belt 3, avoiding the situation that it is difficult to remove the material particle debris on the surface of the conveyor belt 3 during the operation of the conveyor belt 3, resulting in the reduction of the air permeability of the conveyor belt 3 in the subsequent work and affecting the drying of the material. Therefore, the drying air permeability uniformity and drying effect of the conveyor belt 3 are improved.

[0032] Refer to Figures 1 - 4, in a preferred embodiment, the drying and cleaning mechanism includes a cleaning opening 4, the cleaning opening 4 is opened on the left side of the bottom of the drying equipment body 2, and a cleaning cover 5 located outside the cleaning opening 4 is fixedly connected to the left side of the bottom of the drying equipment body 2. A collection box 6 is movably connected to the bottom of the cleaning cover 5. A cleaning rack 7 is movably connected inside the cleaning cover 5. A cleaning brush 8 in contact with the conveyor belt 3 is fixedly connected to the top of the cleaning rack 7. Moving openings 9 are opened on both sides of the cleaning cover 5. Moving rods 10 located inside the moving openings 9 are fixedly connected to both sides of the cleaning rack 7. A flipping and material removing mechanism is movably connected to the top of the cleaning rack 7. By applying a moving force to the cleaning rack 7 through the cooperation of the moving rods 10 and the moving openings 9, the cleaning rack 7 drives the cleaning brush to contact the conveyor belt 3, and the collection box 6 is held and moved to the bottom of the cleaning cover 5 to prepare for collecting material particles. When the conveyor belt 3 operates to drive the material into the drying equipment body 2 for drying and then discharges from the drying equipment body 2, the cleaning brush 8 can brush and clean the residual attached materials and debris particles on the surface of the conveyor belt 3 after discharging, so that the material particle debris is separated from the conveyor belt 3. At this time, the collection box 6 collects the material particle debris cleaned and dropped by the cleaning brush for subsequent unified processing by the user. The flipping and material removing mechanism includes a flipping rod 11, a contact ring 12 and a material removing rack 13. The flipping rod 11 is movably connected to the top of the cleaning rack 7. The flipping rod 11 is located on the right side of the cleaning brush 8. The contact ring 12 is movably connected to the surface of the flipping rod 11. The top of the surface of the contact ring 12 contacts the surface of the conveyor belt 3. The material removing rack 13 is fixedly connected to both sides of the bottom of the flipping rod 11. When the cleaning brush 8 cooperates with the conveyor belt 3 to work, a flipping and poking force can be applied to the material particle debris attached between the bristles on the surface of the cleaning brush 8, so that the material particle debris on the surface of the cleaning brush is separated from the cleaning brush 8, avoiding the situation that it is difficult to clean the material particle debris on the surface of the cleaning brush 8 during the operation of the cleaning brush 8. Therefore, the cleaning convenience of the cleaning brush 8 is improved.

[0033] Refer to Figures 2 - 3 , in a preferred embodiment, by inlaying and connecting a magnetic strip 14 at the bottom of the inner wall of the contact ring 12, and inlaying and connecting a magnetic attraction strip 15 magnetically connected to the magnetic strip 14 on the bottom surface of the flipping rod 11, when the contact ring cooperates with the flipping rod 11 to work, a magnetic attraction connection work can be carried out between the flipping rod 11 and the contact ring 12, avoiding the situation that it is difficult to connect with the flipping rod 11 to apply a flipping force to the flipping rod 11 bracket during the use of the contact ring 12. Therefore, the connection effect between the contact ring 12 and the flipping rod 11 is improved. Support rings 16 are movably connected to both sides of the surface of the flipping rod 11. A support rod 17 is fixedly connected to the bottom of the support ring 16. The bottom of the support rod 17 is fixedly connected to the top of the cleaning rack 7. When the flipping rod 11 cooperates with the material removing rack 13 to work, a rotational connection and support work can be carried out between the flipping rod 11 and the cleaning rack 7, avoiding the situation that the flipping rod 11 is separated from the cleaning rack 7 during the operation of the flipping rod 11. Therefore, the working stability of the flipping rod 11 is improved.

[0034] Reference Figures 3 - 4 , in a preferred embodiment, rolling grooves 18 are provided on both sides of the inner wall of the support ring 16. A ball 19 is movably connected inside the rolling groove 18, and the surface of the ball 19 contacts the surface of the turning rod 11. When the support ring 16 is used in cooperation with the turning rod 11, the contact friction between the turning rod 11 and the support ring 16 can be reduced, and the situation that the friction between the turning rod 11 and the support ring 16 is too large when the turning rod 11 works can be avoided. Therefore, the working smoothness of the turning rod 11 is improved. Rubber rings 20 located outside the moving ports 9 are movably connected to both sides of the cleaning cover 5, and a pressing disk 21 is fixedly connected to the outside of the rubber ring 20. When the moving rod 10 is used in cooperation with the cleaning frame 7, the pressing and positioning work between the cleaning frame 7 and the cleaning cover 5 can be carried out through the moving rod 10, and the situation that it is difficult to position the cleaning frame 7 during use can be avoided. Therefore, the positioning convenience of the cleaning frame 7 is improved.

[0035] Reference Figure 4 , in a preferred embodiment, a threaded hole 22 is provided inside the moving rod 10, and a screw rod 23 is threadedly connected inside the threaded hole 22. The outside of the screw rod 23 is fixedly connected to the inner side of the pressing disk 21. When the pressing disk 21 is used in cooperation with the cleaning frame 7, a moving and pressing force-applying medium can be provided for the pressing disk 21, and the situation that it is difficult to effectively press and position between the cleaning frame 7 and the cleaning cover 5 when the pressing disk 21 is used can be avoided. Therefore, the pressing and positioning effect of the pressing disk 21 is improved. Magnetic plates 24 are inlaid on both sides of the moving rod 10, and magnetic attraction plates 25 magnetically connected to the magnetic plates 24 are inlaid on both sides of the inner wall of the moving port 9. When the moving rod 10 is used in cooperation with the cleaning frame 7, the magnetic attraction pre-positioning work between the cleaning frame 7 and the cleaning cover 5 can be carried out through the moving rod 10, and the situation that it is difficult to perform pre-positioning when the cleaning frame 7 is used, resulting in inconvenient pressing operation of the pressing disk 21, can be avoided. Therefore, the moving pre-positioning convenience of the cleaning frame 7 is improved.

[0036] Specifically, the working process or working principle of the drying equipment for biochar production is as follows: when in use, the hand-held tightening plate 21 drives the moving rod 10 to cooperate with the moving port 9 to apply a moving force to the cleaning rack 7, so that the cleaning rack 7 drives the cleaning brush to contact the conveyor belt 3. At this time, the magnetic plate 24 cooperates with the magnetic suction plate 25 to perform magnetic pre-positioning between the moving cleaning rack 7 and the cleaning cover 5 through the moving rod 10. At the same time, the support rod 17 drives the flipping rod 11 to follow the movement of the cleaning rack 7 through the support rod 17, so that the contact ring 12 contacts the bottom of the transmission belt surface, so that the rotation force of the conveyor belt 3 is used for the subsequent The rod 11 drives the material removal rack 13 to flip and prepare for the cleaning brush to be moved and cleaned. Then, the holding plate 21 drives the screw rod 23 to rotate and cooperate with the screw hole 22 to move the holding plate 21, so that the holding plate 21 drives the rubber ring 20 to contact and tighten with the cleaning cover 5. The cleaning rack and the cleaning cover 5 are tightly positioned by moving the rod 10, and then the collecting box 6 is moved to the bottom of the cleaning cover 5 by hand to prepare for collecting material particles. When the conveyor belt 3 drives the material to enter the drying equipment body 2 for drying and discharge from the drying equipment body 2, the cleaning brush 8 conveys the residual attached materials on the surface of the conveyor belt 3 after the material is discharged. The material can be brushed to remove the debris particles, so that the material particles and debris are separated from the conveyor belt 3. At this time, the contact ring 12 is affected by the rotational force of the conveyor belt 3, and the magnetic strip 14 cooperates with the magnetic attraction strip 15 to drive the flip rod 11 to rotate, so that the material removal frame 13 is flipped and in contact with the cleaning brush, and the material particles and debris attached to the bristles on the surface of the cleaning brush are moved to clean. At this time, the ball 19 rotates inside the rolling groove 18 to reduce the flipping friction between the flip rod 11 and the support ring 16. The material particles and debris cleaned by the material removal frame 13 and the cleaning brush 8 are affected by gravity and move downward into the cleaning cover 5. The material removal rack 13 is inside and is guided by the cleaning cover 5 into the collecting box 6 so that the user can perform unified processing operations later. During this process, when the material removal rack 13 flips over and contacts the conveyor belt 3, it is affected by the position of the conveyor belt 3 and can no longer follow the contact ring 12 to rotate through the flip rod 11. At this time, the contact ring 12 continues to rotate under the influence of the moving force of the conveyor belt 3, and drives the magnetic strip 14 to separate from the magnetic attraction strip 15. After the magnetic strip 14 is separated from the magnetic attraction strip 15, the material removal rack 13 is affected by the downward gravity and drives the flip rod 11 to flip and reset, preparing for the subsequent contact ring 12 to drive the magnetic strip 14 to connect with the magnetic attraction strip 15 by magnetic attraction.

[0037] It should be noted that the drying equipment body 2 and the conveyor belt 3 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
