Description

Technical Field

[0001] The utility model relates to the technical field of activation furnaces, in particular to a vertical activation furnace for activated carbon production. Background Technique

[0002] Activated carbon is a kind of specially treated carbon. The vertical activation furnace mainly places carbon blocks under the condition of 400 to 900 degrees Celsius and conducts an oxidation reaction through a mixed gas of air, water, and carbon dioxide to obtain activated carbon by activation. Its preparation principle is that the carbon atoms with amorphous arrangement in the carbon block preferentially undergo oxidation reaction, resulting in the generation of pore structures in the carbon block, thereby greatly increasing the surface area of the carbon block and making the microporous structure more developed, thus improving the adsorption capacity of the carbon block. Depending on the preparation method and its own properties of activated carbon, it can be used for environmental purification, as a catalyst, in medical clinics, and precious metal extraction, etc. Activated carbon is a recyclable substance. While not damaging the internal structure of activated carbon, cleaning the pore structure inside activated carbon can restore its adsorption capacity.

[0003] Reference patent (CN202320010208.6) discloses a vertical activation furnace for activated carbon production, which relates to the technical field of vertical activation furnaces for activated carbon production, specifically a vertical activation furnace for activated carbon production, including a fixed frame. The top of the fixed frame is fixedly installed with a furnace body. A stirring shaft is rotatably connected inside the furnace body. A fixed block is fixedly installed on the inner side wall of the furnace body. An activity groove is opened inside the fixed block. The outer side of the stirring shaft is rotatably connected inside the activity groove. A driving bevel gear is fixedly installed on the outer side of the stirring shaft. Through the setting of the filter screen, the vertical activation furnace for activated carbon production has the effect of making the carbon blocks move downward under the combined action of gravity and friction force, thereby controlling the activation time of the carbon blocks and classifying the carbon blocks, thus playing a role in improving the activation efficiency of the carbon blocks and achieving the purpose of improving the convenience of the device.

[0004] In the feeding process of traditional vertical activation furnaces for activated carbon production, there are often problems that it is difficult to accurately control the feeding amount of materials. Too much or too little materials will not only cause energy waste, but also may affect the reaction conditions inside the activation furnace, thereby affecting the quality and output of activated carbon. In addition, when the raw materials are fed into the main body of the activation furnace, due to the large falling impact force, it is easy to damage the main body of the activation furnace and shorten its service life. At the same time, the raw materials may collide and break during the free fall process, resulting in problems such as the reduction of the quality specifications of some carbon blocks during the activation process. For this reason, the utility model provides a vertical activation furnace for activated carbon production. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a vertical activation furnace for activated carbon production, which solves the problem that it is difficult to accurately control the feeding amount of materials. Too much or too little materials will not only cause energy waste, but also may affect the reaction conditions in the activation furnace, thereby affecting the quality and output of activated carbon. In addition, when the raw materials are fed into the main body of the activation furnace, due to the large falling impact force, it is easy to damage the main body of the activation furnace and shorten its service life. At the same time, the raw materials may collide and break during the free fall process, resulting in a reduction in the quality specifications of some carbon blocks during the activation process.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A vertical activation furnace for activated carbon production, including the main body of the activation furnace, and a feeding mechanism for activated carbon production is provided on the main body of the activation furnace. The feeding mechanism includes:

[0007] A quantitative component, including a support frame fixedly connected to the upper edge of the main body of the activation furnace. The inner wall of the support frame is fixedly connected with a hydraulic rod, the end of the hydraulic rod is connected with a quantitative tube, a connecting shaft is provided at the edge of the lower end surface of the quantitative tube, a cover plate is connected to the outer surface of the connecting shaft, and a second sealing plate is fixedly connected to the right side of the upper end surface of the quantitative tube;

[0014] Advantages

[0015] The utility model provides a vertical activation furnace for activated carbon production. Compared with the prior art, the following advantages are achieved:

[0016] First, the metering tube of the utility model is pushed forward by a hydraulic rod, and the second sealing plate fixedly connected to the right side of the metering tube squeezes and seals the lower end of the feeding main body. At the same time, the cover plate is far from the first sealing plate, and the cover plate rotates at the lower end of the metering tube through a connecting shaft under the action of gravity. The metering tube moves along the inner side of the protective housing to the feeding port to realize the feeding operation, which can avoid energy waste caused by too much or too little material, prevent potential safety hazards caused by excessive feeding pressure in the activation furnace, control the dosage in time, and avoid blockage caused by continuous feeding.

[0017] Second, when the raw materials are fed into the interior of the activation furnace main body, they are blocked by the buffer plates inclined downward on both sides. Then, the buffer plates play a certain shock absorption and buffering role through the shock absorption springs and damping support rods on the fixed plates at the lower ends of the support rods, which can smoothly guide the raw materials into the interior of the activation furnace main body, reduce the splashing and scattering of the raw materials, and reduce the direct impact of the falling impact force on the activation furnace main body, thereby prolonging the service life of the activation furnace main body, and avoiding the collision and fragmentation of the raw materials during the free fall process, which may cause the reduction of the quality specifications of some carbon blocks during the activation process. Then, the first stirring plate and the second stirring plate are in an inclined downward V-shaped structure, so that the stirring plates can better stir and mix the materials during rotation. The inclined downward structure enables the materials to naturally fall during the stirring process, forming a better convection and mixing effect, which helps the materials to be more evenly distributed and react in the activation furnace, and prevents the materials from accumulating or caking in the activation furnace.
