Description

Technical Field

[0001] This utility model relates to the field of carbonization furnace technology, specifically to a carbonization furnace body structure with a gradient channel. Background Technology

[0002] A carbonization furnace is essentially an industrial device that performs high-temperature pyrolysis in an oxygen-deficient environment, converting organic materials such as wood, straw, and sludge into solid biochar, while simultaneously producing collectable tar and combustible gas. This technology not only realizes the resource utilization of waste but is also widely used in industrial production, agriculture, and environmental protection.

[0003] When materials are fed into the carbonization furnace, they tend to be loose, resulting in uneven accumulation of materials in the carbonization chamber. This hinders the uniform penetration of heat into the materials and affects the carbonization effect. To address this issue, a carbonization furnace structure with a gradient channel is proposed. Summary of the Invention

[0004] The objective of this utility model can be achieved through the following technical solutions: A carbonization furnace body structure with a gradient channel includes a carbonization furnace, wherein a material flow channel is provided inside the carbonization furnace; The material flow channel includes a guide pipe, with support frames fixedly connected to both sides of the guide pipe. Each support frame has a guide rod fixedly connected to its upper and lower ends near the surface of the guide pipe. Each guide rod extends horizontally. A guide groove is provided on one side of the top surface of each support frame. An extrusion block is provided on the inner side of each support frame. A guide hole is provided on one side of the upper and lower ends of each extrusion block. The inner wall of each guide hole is inserted into and slidably connected to the guide rod.

The upper toothed rack extends horizontally as a whole.

[0006] As a further embodiment of this utility model: each of the support frames has a valve plate slidably connected to its inner wall, one end of the valve plate extends below the upper rack and is fixedly connected to the lower rack, and both sides of the bottom surface of the valve plate are fixedly connected to sliders, each slider extends in the horizontal direction, and each slider is slidably connected to the inner wall of the guide groove.

[0007] As a further embodiment of this utility model: a lower sealing gasket is bonded and fixed to the top surface of each valve plate, and the top surface of the lower sealing gasket is slidably connected to the bottom surface of the extrusion block.

[0008] As a further embodiment of this utility model: support beams are fixedly installed on both sides of the outer wall of the guide tube, and an equipment box is fixedly installed on the back of each support frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-5 As shown, a carbonization furnace structure with a gradient channel includes a carbonization furnace 1, and a material transfer channel 2 is provided inside the carbonization furnace 1. The material transfer channel 2 includes a guide pipe 201, and support frames 202 are fixedly connected to both sides of the guide pipe 201. Guide rods 203 are fixedly connected to the upper and lower ends of the surface of each support frame 202 near the guide pipe 201. Each guide rod 203 extends horizontally. A guide groove 204 is opened on one side of the top surface of each support frame 202. An extrusion block 208 is provided on the inner side of each support frame 202. Guide holes 210 are opened on the upper and lower ends of one side of each extrusion block 208. The inner wall of each guide hole 210 is inserted into and slidably connected to the guide rod 203. The side of the extrusion block 208 away from the guide hole 210 is set as an inclined surface, and the thickness of the extrusion block 208 gradually increases from top to bottom. Figure 3 As shown, the guide rod 203, in conjunction with the guide hole 210, limits the movement direction of the extrusion block 208.

[0018] Each extrusion block 208 has an upper sealing gasket 209 bonded and fixed to its top and sides. The top and sides of the upper sealing gasket 209 are slidably connected to the inner wall of the guide tube 201. Each extrusion block 208 has a groove 211 in the center of its bottom surface. An upper toothed rack 212 is fixedly connected inside each groove 211. The upper toothed rack 212 extends horizontally as a whole. Figure 3As shown, the upper sealing gasket 209 and the lower sealing gasket 214 can be made of modified PTFE material, which has strong wear resistance and low coefficient of friction, such as GYLON3504 gasket.

[0019] Each support frame 202 has a valve plate 213 slidably connected to its inner wall. One end of the valve plate 213 extends below the upper rack 212 and is fixedly connected to a lower rack 216. Slider blocks 215 are fixedly connected to both sides of the bottom surface of the valve plate 213. Each slider 215 extends horizontally and is slidably connected to the inner wall of the guide groove 204. Figures 2-5 As shown, the slider 215, in conjunction with the guide groove 204, limits the movement direction of the valve plate 213, while preventing the valve plate 213 from moving too far and preventing the gear and rack structure from disengaging.

[0020] Each valve plate 213 has a lower sealing gasket 214 bonded to its top surface, and the top surface of the lower sealing gasket 214 is slidably connected to the bottom surface of the extrusion block 208.

[0021] Support beams 217 are fixedly installed on both sides of the outer wall of the feed pipe 201. Equipment boxes 205 are fixedly installed on the back of each support frame 202. Servo motors 206 are supported and fixedly connected inside the equipment box 205. The output shafts of each servo motor 206 pass through the support frame 202 and extend below the groove 211. Gears 207 are fixedly connected to the output shafts of the servo motors 206. The top surface of the gear 207 meshes with the upper rack 212, and the bottom surface of the gear 207 meshes with the lower rack 216. Figure 2 As shown, the servo motor 206 can be a 1FT7 servo motor, and the servo motor connection cable can be led out through the internal cable groove of the support beam 217.

[0022] The carbonization furnace 1 includes a furnace body 101. A feed inlet 102 is connected through and fixedly connected to the top of the furnace body 101, and a discharge outlet 103 is connected through and fixedly connected to the bottom of the furnace body 101. A shelf 105 is fixedly connected to the upper end of the inner wall of the furnace body 101, and the inner diameter of the shelf 105 gradually decreases from top to bottom. An electric heating tube 104 is fixedly installed in the upper interlayer of the furnace body 101. Figure 1 As shown, heat insulation material is provided on the outside of the electric heating tube 104 to reduce heat conduction to the outside of the furnace body 101.

[0023] The inner wall of the furnace body 101 is fixedly connected to the two support beams 217, and the bottom surface of the shelf 105 is connected to the guide pipe 201 and fixedly connected.

[0024] The working principle of this utility model: When the device is in use, a support frame should be welded to the outside of the furnace body 101. Conveying pipes and valve structures should then be connected to the ends of the feed inlet 102 and discharge outlet 103, respectively. Material falls through the discharge outlet 103 onto the shelf 105, then descends along an inclined plane into the guide pipe 201. During this process, the material is supported by the compression blocks 208 on both sides, causing it to be compressed before entering the carbonization zone, resulting in a more uniform material density. When the servo motor 206 is started, driving the gear 207 to rotate, the simultaneous transmission of the upper rack 212 and lower rack 216 causes the two compression blocks 208 to move relative to each other in the horizontal direction, thereby reducing the distance between the compression blocks 208 and further compressing the material inside the guide pipe 201. At the same time, the two valve plates 213 also move relative to each other in the horizontal direction, but the distance between the valve plates 213 increases. At this time, the material near the lower end of the extrusion block 208 is subjected to the greatest degree of extrusion, so the material particle size is smaller and there are fewer lumps, so it can continue to fall into the carbonization chamber. The material near the upper end of the extrusion block 208 is subjected to a smaller degree of extrusion and is more prone to lumps, so the material is more likely to be supported between the extrusion blocks 208 and form a blockage. The material with more lumps is not easy to continue to fall. However, when the distance between the two extrusion blocks 208 increases, the material continues to fall above the valve plate 213. By repeating the above steps, the material above the shelf 105 can be gradually extruded through the guide pipe 201 and fall into the carbonization chamber.

[0025] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
