DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The technical scheme provided by each embodiment of the present application will be described in detail below in combination with the drawings.

[0029] Reference Figures 1 to 6The utility model provides a novel reed manufacturing active carbon equipment, mainly includes material drying cylinder 1, carbonization cylinder 2, high temperature activation cylinder 3, water spraying activation cylinder 4 and cooling cylinder 5 that are sequentially connected with each other. These function cylinder bodies are connected using sealing rings, forming a complete closed system. Among them, the upper portion of material drying cylinder 1 is provided with a feeding portion 11 for continuous feeding of materials; the upper portion of cooling cylinder 5 is provided with a discharging portion 52 for facilitating the discharge of finished products. In order to realize the orderly conveying of materials, a material moving structure 7 is arranged between carbonization cylinder 2, high temperature activation cylinder 3 and water spraying activation cylinder 4. At the same time, a feeding conveying structure is installed in material drying cylinder 1, and a discharging conveying structure is provided in cooling cylinder 5, which together ensure the continuity and stability of the entire production process.

[0030] It should be noted that material drying cylinder 1, carbonization cylinder 2, high temperature activation cylinder 3, water spraying activation cylinder 4 and cooling cylinder 5 are all made of 310S high-grade stainless steel into a round cylinder shape, and the lengths of material drying cylinder 1, carbonization cylinder 2, high temperature activation cylinder 3, water spraying activation cylinder 4 and cooling cylinder 5 are 14m, 10m, 8m, 8m and 8m respectively.

[0031] In the process of use, reed segments are conveyed into material drying cylinder 1 through feeding portion 11, and the reed segments are conveyed forward through the work of the feeding conveying structure, which can continuously push and convey the reed segments forward, carbonization cylinder 2 performs carbonization treatment on the reed segments, high temperature activation cylinder 3 performs high temperature activation on the reed segments, water spraying activation cylinder 4 performs spraying activation on the reed segments, and cooling cylinder 5 performs cooling treatment on the reed segments. Through the work of the discharging conveying structure, the active carbon can be discharged outward through discharging portion 52.

[0032] In the preferred embodiment of the utility model, the feeding conveying structure adopts the combination of feeding motor 8 and feeding spiral blade 81. Specifically, feeding motor 8 is fixed on the side wall of material drying cylinder 1, and the main shaft of feeding motor 8 drives the rotation of feeding spiral blade 81 in the cylinder body. This design not only ensures the continuity of material conveying, but more importantly, it realizes the uniform turning of materials through the rotation of spiral blade, greatly improving the drying effect. In addition, feeding spiral blade 81 is rotatably connected with material drying cylinder 1 in a bearing support manner, effectively reducing the running resistance and prolonging the service life of the equipment.

[0033] In order to further improve the thermal efficiency of the equipment, a layer of heat preservation material is wrapped on the outer wall of the material drying cylinder 1 and is subjected to sealing treatment. This heat preservation design not only can reduce heat loss, but also can maintain the stability of the internal temperature of the cylinder body, which is of great significance to improve the product quality. Preferably, heat-resistant insulation cotton is used as the heat preservation material, which not only ensures the heat preservation effect, but also has good cost performance. The feeding motor 8 drives the feeding spiral blade 81 to rotate, which can drive the bamboo cane segments to overturn and continuously convey forward, directly dries the materials by using the waste heat, and the subsequent carbonization of the bamboo cane segments is carried out. The heat preservation material is provided to preserve the temperature during drying.

[0034] Next, the gas outlet cylinder 21 is designed at the top of the carbonization cylinder 2, and the flue gas recovery combustion heating room 22 is installed above it. This design embodies a big innovation point of the utility model, that is, the recycling of flue gas is realized. When the flue gas generated during the carbonization of the bamboo cane rises through the gas outlet cylinder 21, it enters the flue gas recovery combustion heating room 22 for secondary combustion. This not only reduces energy consumption, but also significantly reduces pollutant emissions, embodying the environmental protection concept of the utility model.

[0035] When the bamboo cane segments are carbonized in the carbonization cylinder 2, the flue gas can be discharged outward through the gas outlet cylinder 21, and the flue gas recovery combustion heating room 22 can make the flue gas recovery combustion, so that the combustible components can be burned again to release heat; the room gas is discharged, and the pollutant concentration is reduced.

[0036] In the high-temperature activation cylinder 3, the electromagnetic heating wire 31 is innovatively arranged. The electromagnetic heating wire 31 can continuously heat the temperature of the high-temperature activation cylinder 3 to 1100 degrees. Compared with the traditional heating, this heating mode is more accurate and controllable, and the temperature can be accurately adjusted to the required temperature, so that the temperature stability of the activation process is ensured. The installation position of the electromagnetic heating wire 31 is optimized and designed to ensure the uniformity of heating and avoid the occurrence of local overheating.

[0037] It is worth mentioning that the high-temperature water pipe 41 is installed at the inner top of the water spraying activation cylinder 4, and a plurality of atomizing nozzles 42 are uniformly distributed on it. The high-temperature water pipe 41 is connected with the external water supply system through the water inlet pipe 43 extending to the outside of the cylinder body, and the water inlet pipe 43 is provided with a regulating valve 44. By controlling the opening degree of the valve 44, the spraying amount can be accurately adjusted, so that the activation process can be accurately controlled. The design of the atomizing nozzle 42 is particularly key, and the spraying mode of the atomizing nozzle 42 can make the water mist uniformly cover the entire activation area, thereby improving the contact efficiency of water and materials.

[0038] When water spraying is needed, open the valve 44 to spray water onto the carbonized material through atomization, which can prevent local overheating: During the carbonization process, the material will undergo a series of complex thermochemical reactions, such as dehydration, pyrolysis, etc. If there is no proper temperature control, local overheating is likely to occur. Spraying water can absorb heat, and when the local temperature is too high, the evaporation of the atomized water will take away the heat, so that the carbonization reaction can be carried out in a more uniform temperature range; stabilize the reaction temperature: Carbonization reaction usually needs to be carried out in a specific temperature range to obtain ideal carbonization products. Spraying water can be an effective means of temperature regulation, by controlling the amount of atomized water sprayed, the carbonization temperature can be stabilized near the target temperature. For example, for some biomass carbonization, the appropriate carbonization temperature may be between 400-600℃, when the temperature has a rising trend beyond this range, spraying atomized water can lower the temperature, so that it returns to the appropriate range.

[0039] This modular design not only improves the maintenance convenience of the equipment, but also reserves sufficient adjustment space for subsequent process optimization. The entire system realizes the continuity and automation of the production process through the carefully designed transmission mechanism and control system, significantly improving the production efficiency and stability of the product quality.

[0040] In another embodiment of the present application, the structure of the cooling cylinder 5 is also quite characteristic. It is internally provided with a sandwich layer 51, and cooling water is circulated into the sandwich layer 51, forming a complete cooling system. The flow of circulating water can cool the carbonized material, so that the carbonized material is cooled, achieving the purpose of continuous production of cooling and discharging at the same time. The advantage of this sandwich type cooling design is that the cooling effect is more uniform, and the flow and temperature of the cooling water can be adjusted according to actual needs to realize precise temperature control. By reasonably designing the thickness of the sandwich layer and the water flow channel, not only the cooling efficiency is ensured, but also the problem of product cracking caused by sudden temperature drop is avoided.

[0041] In order to realize the continuous output of finished products, the present application designs a discharging conveying structure in the cooling cylinder 5. Specifically, the structure includes a discharging motor 9 and a discharging spiral impeller 91. The discharging motor 9 is fixedly installed at a proper position of the cooling cylinder 5, and is connected with the discharging spiral impeller 91 through its main shaft. The discharging spiral impeller 91 is rotatably connected with the cooling cylinder 5 through a bearing, which not only ensures the smoothness of operation, but also reduces mechanical wear. It is worth noting that the pitch and rotational speed of the discharging spiral impeller 91 are carefully calculated, which can not only ensure the continuous output of the material, but also will not affect the cooling effect. After the reed canary grass is carbonized, the discharging motor 9 drives the discharging spiral impeller to rotate in the cooling cylinder 5, conveying the carbonized material forward through the discharging part 52 to discharge it outward, which can also speed up the cooling speed of the carbonized material.

[0042] An important innovation of the utility model lies in the design of the material moving structure 7. The structure comprises a first rotating shaft 71, a second rotating shaft 72 and a rotating motor 73, forming a complete transmission system. Among them, the first rotating shaft 71 and the second rotating shaft 72 are respectively installed on the carbonization cylinder 2 and the water spraying activation cylinder 4, and realize stable rotation through bearings. On the two rotating shafts, two first sprockets 74 and two second sprockets 75 are respectively arranged, and a transmission chain is formed by connecting through chains 76. Especially worth mentioning is that the two parallel chains 76 are provided with mounting plates 77, and a plurality of moving rods 78 are uniformly distributed on the bottom of the mounting plates 77. The ingenious part of this design is that when the rotating motor 73 starts, the moving rods 78 can be driven to move in order through the chain transmission system, so that the uniform advancement of the material is realized.

[0043] The design of the moving rod 78 is particularly critical. These rod members not only consider the strength requirement, but also consider the high temperature resistance. By optimizing the cross-sectional shape and arrangement spacing of the rod members, sufficient thrust is ensured, and accumulation and adhesion of the material are avoided. In addition, the design of the mounting plate 77 is also carefully considered, and the weight and strength need to reach a suitable balance point, which not only ensures the stability of the structure, but also cannot bring too large load to the transmission system.

[0044] After the bamboo cane segments are conveyed forward into the carbonization chamber through the feeding conveying structure, the rotating motor 73 can drive the first rotating shaft 71 to rotate, the first rotating shaft 71 can drive the two first sprockets 74 to rotate, thereby driving the two second sprockets 75 to rotate through the two chains 76, so that the second rotating shaft 72 rotates, thereby moving the position of the bamboo cane segments through the plurality of moving rods 78 on the bottom of the mounting plate 77, moving the bamboo cane segments from the carbonization cylinder 2 into the high-temperature activation cylinder 3 and the water spraying activation cylinder 4 respectively, so as to carry out carbonization work on the bamboo cane segments subsequently.

[0045] Another advantage of this chain transmission mode is its maintenance convenience. When it is necessary to overhaul or replace parts, the relevant parts can be conveniently disassembled without affecting the integrity of the whole system. At the same time, the chain transmission has good reliability and durability, and can maintain stable operation even in a high temperature environment. The selection of the rotating motor 73 is also very critical, which needs to have sufficient torque and speed regulation range to adapt to the operation requirements under different working conditions.

[0046] Through this carefully designed material moving structure, the utility model successfully realizes the continuous and stable conveying of the material between different functional areas. The whole system runs stably and reliably, greatly improves the production efficiency and reduces the operation and maintenance cost. At the same time, this modular design concept also reserves sufficient space for subsequent process improvement and equipment upgrading.

[0047] With the synergies of the above various functional components, the continuous and automatic production of the reed active carbon is successfully realized. The whole set of equipment is not only more accurate in process control, but also has achieved significant improvement in energy utilization efficiency, fully embodying the design concept of modernized equipment. Especially in the environmental protection performance, through the smoke recycling, accurate temperature control and other measures, the development concept of green production is well implemented.

[0048] The above merely illustrates the embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
