Description

Technical Field

[0001] This utility model relates to the field of activated carbon processing technology, and in particular to a high-efficiency and energy-saving vertical coal-based activated carbon calcining furnace with a multi-layer heat insulation structure. Background Technology

[0002] Activated carbon, as a carbon material with a well-developed pore structure, huge specific surface area and excellent adsorption capacity, has indispensable applications in many fields. It is stable, can withstand acids and alkalis, and can adapt to water-humid, high-temperature and high-pressure environments. In modern life, with the enhancement of environmental awareness and the increasing demand for high-quality purification in industrial production, the market demand for activated carbon continues to grow. Calcination furnaces are required when processing activated carbon.

[0003] Uneven heating in the calcination furnace can lead to inconsistent activation levels of activated carbon. Some areas may be over-activated, damaging the pore structure and affecting adsorption performance; while other areas may be under-activated, with incomplete pore development and a smaller specific surface area. Ultimately, this reduces the overall adsorption performance of the activated carbon, resulting in unstable product quality and an inability to meet high-quality requirements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency, energy-saving, vertical coal-based activated carbon calciner with a multi-layered heat-insulating structure. A first motor drives a rotating rod, which in turn drives a connecting plate. When the connecting plate rotates, gears and a gear ring engage to drive a rotating shaft. The rotating rod and shaft then drive a stirring plate to stir the activated carbon. At this time, an air heater is activated to draw in and heat external air. The heated air enters through the air inlet and exits through the air outlet, ensuring that each particle or layer of raw material receives heat evenly, preventing localized overheating or underheating, and contributing to improved calcination effect and product quality stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 2-4This utility model provides an embodiment of a high-efficiency, energy-saving, vertical coal-based activated carbon calcining furnace with a multi-layer heat-insulating structure, comprising: a support base 1 serving as the main support; a combustion furnace 2 fixedly connected to the inner wall of the support base 1; a fixed box 3 fixedly connected to the top of the combustion furnace 2; a first motor 4 fixedly connected to the top of the fixed box 3; a drive end of the first motor 4 penetrating the fixed box 3 and fixedly connected to a rotating rod 5; a connecting plate 6 fixedly connected to the outer wall of the rotating rod 5; a rotating shaft 9 connected to the connecting plate 6 via a transmission assembly; stirring plates 10 fixedly connected to the outer walls of both the rotating rod 5 and the rotating shaft 9; an air heater 11 fixedly connected to the right side of the top of the combustion furnace 2; the left end of the air heater 11 fixedly connected to the right end of the fixed box 3; and the bottom end of the combustion furnace 2... An anti-clogging component is provided. An aerogel 24 is fixedly connected to one side of the inner wall of the combustion furnace 2. A ceramic fiber 25 is fixedly connected to the rear end of the aerogel 24. A rock wool board 26 is fixedly connected to the rear end of the ceramic fiber 25. The transmission component includes a gear 7 located on the outer wall of the rotating shaft 9 and a gear ring 8 located on the inner wall of the combustion furnace 2. The gear 7 and the gear ring 8 are meshed together. The outer wall of the rotating shaft 9 is rotatably connected to the inner wall of the connecting plate 6. A feed port 14 is fixedly connected to the left end of the combustion furnace 2. A cover plate 15 is threadedly connected to the outer wall of the feed port 14. A discharge port 16 is fixedly connected to the bottom end of the combustion furnace 2. A control valve is provided on the outer wall of the discharge port 16. An air inlet 12 is provided on the upper inner wall of the rotating rod 5. An air outlet 13 is provided on the lower inner wall of the rotating rod 5.

[0026] Specifically, aerogel 24 is one of the solid materials with the lowest thermal conductivity and density, possessing microstructural characteristics such as high specific surface area and high porosity. In calcining furnaces, it can significantly reduce heat conduction, with an insulation effect 2-5 times that of traditional insulation materials, reducing heat loss from the furnace body and improving energy utilization efficiency. Ceramic fiber 25 has advantages such as light weight, high temperature resistance, low heat capacity, and good thermal insulation performance, effectively blocking heat transfer, reducing the external temperature of the furnace body, and reducing heat loss. Rock wool board 26 is made primarily from basalt and other raw materials. Lightweight thermal insulation material with good thermal insulation and excellent fire resistance. In calcining furnaces, it can serve as an insulation layer to prevent heat loss, helping to maintain a high-temperature environment inside the furnace and improve calcination efficiency. Aerogel 24, ceramic fiber 25, and rock wool board 26 form a three-layer insulation system, reducing the outer wall temperature of the furnace to below 60℃ and reducing heat loss by more than 30%, thus achieving multi-layer insulation. The air heater 11, model FH002, heats the intake cold air and then delivers it to the required location. During operation, it will... Activated carbon is fed into the combustion furnace 2 through the feeding port 14. The combustion furnace 2 then starts the direct heating mode to begin the calcination process of the activated carbon inside. Next, the first motor 4 is started, and the rotational power of its drive end is transmitted to the rotating rod 5, causing the rotating rod 5 to rotate synchronously. When the rotating rod 5 rotates, the connecting plate 6 rotates accordingly. The movement of the connecting plate 6 causes the gear 7 and the gear ring 8 to mesh and drive each other, thereby driving the rotating shaft 9 to rotate. The coordinated rotation of the rotating rod 5 and the rotating shaft 9 drives the stirring plate 10 to rotate continuously, stirring the activated carbon in the furnace in all directions. At the same time, the air is turned on. The gas heater 11 draws in external air and heats it rapidly. The heated air is then discharged into the fixed box 3. After accumulating in the fixed box 3, the hot air enters the combustion furnace 2 through the air inlet 12 and is finally discharged from the air outlet 13. During this process, the hot air circulates within the furnace, ensuring that each particle of activated carbon and each layer of raw material can fully and evenly absorb heat. This effectively avoids situations where the local temperature is too high or too low, greatly improving the calcination effect and ensuring the stability of product quality. By improving the calcination effect, high efficiency and energy saving are achieved.

[0027] Reference Figure 1 and Figure 5 The anti-blocking component includes a connecting frame 17 fixedly connected to the bottom of the combustion furnace 2. A slide rod 18 is slidably connected to the inner wall of the connecting frame 17. A spring 20 is provided between the slide rod 18 and the inner wall of the connecting frame 17. A fixing plate 21 is fixedly connected to the rear end of the connecting frame 17. A second motor 22 is fixedly connected to the rear end of the fixing plate 21. The drive end of the second motor 22 passes through the fixing plate 21 and is fixedly connected to a cam 23. Multiple push plates 19 are fixedly connected to the outer wall of the slide rod 18. One end of the spring 20 is connected to the slide rod 18, and the other end of the spring 20 is connected to the inner wall of the connecting frame 17.

[0028] Specifically, when the calcined activated carbon needs to be discharged, the operator opens the control valve, and the material begins to fall from the discharge port 16. At this time, the second motor 22 is started, and its drive end drives the cam 23 to start rotating. As the cam 23 rotates, when the convex part contacts the slide rod 18, a lateral thrust is generated, pushing the slide rod 18 forward. During the movement of the slide rod 18, the push plate 19 connected to it moves synchronously, applying a thrust to the falling activated carbon, so that the material can pass smoothly through the discharge channel. This action effectively avoids the material from accumulating and causing blockage during the discharge process, ensuring that the activated carbon can be discharged stably and continuously according to the production process requirements, reducing the number of equipment downtime maintenance due to blockage failures, and significantly improving production efficiency. When the cam 23 continues to rotate and the convex part gradually leaves the slide rod 18 and turns into a round surface contact, the spring 20 installed on the slide rod 18 quickly takes effect, using elastic potential energy to spring back the slide rod 18 to reset, preparing for the next pushing action, thus forming a continuous and stable anti-blockage discharge mechanism.

[0029] Working principle: First, activated carbon is fed into the combustion furnace 2 through the feed port 14. The combustion furnace 2 directly heats and calcines the activated carbon inside. Then, the first motor 4 is started, causing its drive end to rotate, which in turn drives the rotating rod 5. The rotating rod 5, in turn, drives the connecting plate 6 to rotate. As the connecting plate 6 rotates, the gear 7 and gear ring 8 engage, driving the rotating shaft 9 to rotate. The rotation of the rotating rod 5 and shaft 9 drives the stirring plate 10 to stir the activated carbon. At this time, the air heater 11 is turned on to draw in external air for heating. The heated air is discharged into the fixed box 3, and the hot air in the fixed box 3 enters through the air inlet 12 and then exits through the air outlet 13. This ensures that each particle or layer of raw material receives heat evenly, avoiding localized overheating or underheating. This helps improve the calcination effect and product quality stability. When material needs to be discharged, the control valve is opened and the calcined activated carbon is discharged from the discharge port 16. At this time, the second motor 22 is started, and its drive end rotates, causing the cam 23 to rotate. When the cam 23 rotates to the convex surface, it drives the slide rod 18 to move. When the slide rod 18 moves, it drives the push plate 19 to push the activated carbon, thereby avoiding the accumulation and blockage of materials during material discharge. This ensures that the materials flow smoothly according to the process requirements, avoids downtime for maintenance due to blockage, and improves production continuity. When the cam 23 rotates to the circular surface, the spring 20 will bounce the slide rod 18 and then reset it.
