Description

Technical Field

[0001] This utility model relates to the field of environmental protection and resource recycling technology, and in particular to a reactor for preparing walnut shell activated carbon. Background Technology

[0002] Walnut shell activated carbon is a functional adsorbent material made from walnut shells through high-temperature carbonization and activation processes. It possesses a rich pore structure and a large specific surface area, resulting in excellent adsorption performance and applications in water treatment, air purification, and many other fields. The activated carbon preparation reactor is the core device in the entire production process. By precisely controlling reaction conditions such as temperature, pressure, and activator concentration, it ensures that the walnut shells undergo sufficient physicochemical reactions during carbonization and activation, effectively forming a well-developed pore structure. This guarantees the adsorption performance and product quality of the activated carbon, achieving a highly efficient conversion from raw materials to high-value-added activated carbon products.

[0003] When the reactor for preparing walnut shell activated carbon is in operation, the walnut shell raw material is first fed into the reactor. In an environment where oxygen is isolated or restricted, the walnut shell is heated to cause pyrolysis and carbonization, removing volatiles and forming a preliminary carbon skeleton. Subsequently, activators such as water vapor and carbon dioxide are introduced, and they react chemically with the carbon skeleton at high temperature, etching the carbon surface and expanding and connecting the pore structure. At the same time, parameters such as reaction temperature, activator flow rate, and reaction time are adjusted to precisely control the pore size and distribution, and finally, walnut shell activated carbon with high adsorption performance is produced.

[0004] However, some existing walnut shell activated carbon preparation reactors suffer from easy clogging during use. This is because walnut shells are irregularly shaped and vary significantly in size, and are prone to fragmentation due to mutual compression and friction during transport. Furthermore, some existing reactors have poorly designed inlet structures, lacking effective anti-clogging pretreatment mechanisms and drainage structures. This leads to walnut shell accumulation, entanglement, and even the formation of a dense clogging layer upon entering the reactor. This clogging problem not only severely impacts the production efficiency of walnut shell activated carbon and increases the frequency of equipment shutdowns for cleaning, but also causes uneven feeding, resulting in unbalanced reaction conditions within the reactor and reduced activated carbon product quality. This leads to a double loss in production efficiency and economic benefits for enterprises. Therefore, a walnut shell activated carbon preparation reactor is proposed to address these issues.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 2 to 4 This utility model provides an embodiment of a walnut shell activated carbon preparation reactor, comprising a base plate 1. Multiple supports 2 are fixedly connected to the top of the base plate 1, vertically fixed to the top of the base plate 1, transferring the weight of components such as the feed hopper 3 and the fixing mechanism 5 to the base plate 1. A feed hopper 3 is fixedly connected to an adjacent side of the multiple supports 2. The feed hopper 3 is fixed above the base plate 1 by the supports 2 and is the core area of ​​the device for receiving and temporarily storing materials. Its internal space is designed according to the storage requirements of the materials and can accommodate a certain amount of materials to be processed. An anti-blocking mechanism 4 is fixedly connected to the front side of the feed hopper 3. The anti-blocking mechanism 4 is installed on the front side of the feed hopper 3 and is a key component to prevent material from clogging inside the feed hopper 3.

[0026] A fixing mechanism 5 is fixedly connected to the top of the base plate 1. The fixing mechanism 5 is directly installed on the top of the base plate 1 and is used to fix other important components in the device. The anti-blocking mechanism 4 includes two functional compartments 41. The functional compartments 41 adopt a sealed design, which can effectively protect the internal mechanical structure from the influence of material dust, moisture and other factors, and extend the service life of the equipment. The adjacent sides of the two functional compartments 41 are fixedly connected to the front and rear sides of the feed hopper 3. The fixed connection between the functional compartments 41 and the feed hopper 3 ensures efficient transmission of power and motion, so that the anti-blocking mechanism 4 can process the material in the feed hopper 3 in a timely manner during operation and prevent blockage. The inner walls of the two functional compartments 41 are respectively fixedly connected to sliding compartments 47. The sliding compartments 47 are fixed to the inner walls of the functional compartments 41, forming a track space for the moving block 48 to slide.

[0027] A power shaft 42 is fixedly connected to the inner wall of the two functional compartments 41 on their opposite sides. The power shaft 42, mounted on the inner wall of the opposite side of the functional compartments 41, serves as the core component for power transmission; one end is connected to an external power source, and the other end is connected to a power gear 43. A power gear 43 is fixedly connected to the outer side of the two power shafts 42 on their adjacent sides. The power gear 43 is mounted on the end of the power shaft 42 and transmits the rotational motion of the power shaft 42 to the connecting gear 46 through meshing. A rotating shaft 45 is fixedly connected to the inner wall of the two functional compartments 41 on their opposite sides. The rotating shaft 45 is fixed to the inner wall of the functional compartment 41, providing a fulcrum for the connecting gear 46 to rotate around its axis.

[0028] Connecting gears 46 are fixedly connected to the outer sides of two adjacent rotating shafts 45. The connecting gears 46 are mounted at the ends of the rotating shafts 45 and mesh with the power gears 43, converting the rotational power transmitted by the power gears 43 into their own rotation. Multiple moving blocks 48 are slidably connected to the inner walls of two hoppers 47. When the connecting gears 46 rotate, they drive the moving blocks 48 to move linearly within the hoppers 47 via rack and pinion engagement or other transmission methods. The movement of the moving blocks 48 is then transmitted to the stirring assembly 49, enabling the stirring assembly 49 to reciprocate within the feed hopper 3. The stirring assembly 49 is fixedly connected to the adjacent sides of the multiple moving blocks 48. When the moving blocks 48 slide within the hoppers 47, they drive the stirring assembly 49 to reciprocate within the feed hopper 3, ensuring the flowability of the material within the feed hopper 3 and effectively preventing blockages.

[0029] Reference Figures 3 to 5The fixing mechanism 5 includes an isolation chamber 51. The bottom end of the isolation chamber 51 is fixedly connected to the top end of the base plate 1. This connection method forms a stable integral structure between the isolation chamber 51 and the base plate 1, ensuring that the isolation chamber 51 will not shift or shake during operation. A connecting pipe 52 is fixedly connected to the inner wall of the top end of the isolation chamber 51. The connecting pipe 52, fixed to the inner wall of the top end of the isolation chamber 51, serves as a channel connecting the isolation chamber 51 to the exhaust system of external equipment. Multiple slots are provided at the bottom end of the connecting pipe 52 for engaging and fixing with other components.

[0030] Multiple contraction columns 53 are fixedly connected to the bottom of the connecting pipe 52. These columns are extended and retractable, and their structural design allows for free expansion and contraction within a certain range. Each of the contraction columns 53 is fitted with a spring 54. When the column 53 is compressed by an external force, the spring 54 is compressed and stores elastic potential energy; when the external force disappears, the spring 54 releases the elastic potential energy, pushing the column 53 back to its original position. Limiting blocks 56 are fixedly connected to opposite sides of the multiple contraction columns 53. These limiting blocks 56 are used to fix the position of the fixing ring 55, preventing it from detaching. A fixing ring 55 is also fixedly connected to the bottom of the connecting pipe 52, securely connected to it via a slot.

[0031] The bottom of the retaining ring 55 is designed with an interface for connecting to the collection bag 57, ensuring the secure installation of the collection bag 57. The collection bag 57 is fixedly connected to the bottom end of the retaining ring 55, and the collection bag 57 is connected to the connecting pipe 52 through the retaining ring 55 for filtering the gas delivered from the connecting pipe 52. The top end of the connecting pipe 52 is fixedly connected to the exhaust pipe 10. During the exhaust process, the exhaust pipe 10 can be used in conjunction with filtration devices, purification equipment, etc., to treat the emitted gas and reduce environmental pollution.

[0032] Reference Figures 1 to 3 The mixing assembly 49 includes fixed rods 491. The distant ends of multiple fixed rods 491 are respectively fixedly connected to the adjacent ends of multiple movable blocks 48. This multi-point fixed connection enhances the reliability of the connection between the mixing assembly 49 and the movable blocks 48, enabling the mixing assembly 49 to accurately respond to the movement of the movable blocks 48 and effectively mix the materials in the feed bin 3. Contact rods 492 are fixedly connected to the outside of each of the multiple fixed rods 491. As these contact rods move with the fixed rods 491, they can fully mix, agitate, and break up the materials, effectively preventing material agglomeration and accumulation, and ensuring the flowability and uniformity of the materials. Baffles 495 are fixedly connected to the adjacent ends of the two functional bins 41. Their main function is to limit the movement range of the mixing assembly 49, preventing the fixed rods 491 and contact rods 492 from exceeding the predetermined area during movement, and avoiding collisions or interference with other components.

[0033] Two functional compartments 41 are each fixedly connected to a fixed column 494 on an adjacent side, providing stable support for the partition 493. A partition 493 is also fixedly connected to an adjacent side of the two fixed columns 494, installed between the fixed columns 494 to separate the space within the feed hopper 3, allowing materials to flow and mix within a specific area during the mixing process. Multiple fixed rods 491 are externally slidably connected to the outside of the partition 493, providing guidance and support for the movement of the fixed rods 491. The external surfaces of the multiple fixed rods 491 are also slidably connected to the inner wall of the baffle 495. When the fixed rods 491 move with the moving block 48, they are constrained by the inner wall of the baffle 495 and can only slide within a predetermined area, preventing damage to the equipment or affecting the mixing effect due to uncontrolled movement of the mixing assembly 49, while also protecting the safety of the operators.

[0034] Two rotating shafts 45 are externally connected to toothed chains 44, which are connected to the rotating shafts 45 via gear meshing. As a key component for power transmission, the toothed chains 44 convert the rotational motion of the rotating shafts 45 into linear motion. The external parts of two connecting gears 46 are meshed with the external parts of the two toothed chains 44. When the connecting gears 46 rotate under the drive of the power gear 43, they convert the rotational power into linear motion of the toothed chains 44 through meshing, thereby driving the moving blocks 48 and the stirring assembly 49. The external parts of multiple moving blocks 48 on adjacent sides are meshed with the external parts of the toothed chains 44. The moving blocks 48 receive the power transmitted by the toothed chains 44 through meshing, achieving linear motion within the hopper 47.

[0035] Multiple springs 54 are externally slidably connected to the inner wall of the bottom end of the connecting pipe 52. When the contraction column 53 is compressed or stretched by external force, the springs 54, constrained by the inner wall of the connecting pipe 52, will not shift or jam, ensuring the stability of the connection structure between the fixing ring 55 and the collection bag 57. Multiple limiting blocks 56 are externally slidably connected to the inner wall of the bottom end of the connecting pipe 52. When the contraction column 53 extends or retracts, the limiting blocks 56 slide on the track on the inner wall of the connecting pipe 52. When the limit position is reached, the limiting blocks 56 cooperate with the corresponding structure on the inner wall of the connecting pipe 52 to prevent the contraction column 53 from continuing to extend or retract, preventing excessive movement and damage to the connection structure. The inner wall of the fixing ring 55 has a limiting groove, which works in conjunction with the limiting blocks 56 to provide guidance and positioning for the sliding of the limiting blocks 56. Multiple limiting blocks 56 are externally fixedly connected to the inside of the fixed ring 55 on opposite sides. When the contraction column 53 extends or retracts, the limiting blocks 56 drive the fixed ring 55 to move synchronously.

[0036] Multiple mounting brackets 6 are fixedly connected to the top of the base plate 1, providing stable support for the reaction chamber 7. The brackets 6 are evenly distributed, distributing the weight of the reaction chamber 7 and the pressure generated during operation evenly across the base plate 1. The tops of the brackets 6 are fixedly connected to the reaction chamber 7, which is mounted above the base plate 1 via the brackets 6 and is the core area for chemical reactions or material processing. A conveying pipe 8 is fixedly connected to the right side of the reaction chamber 7. The conveying pipe 8 is made of corrosion-resistant and wear-resistant materials, and its diameter and length are designed according to the material flow rate and conveying distance to ensure smooth material transport.

[0037] The bottom of the feeding hopper 3 is fixedly connected to the inlet 9. The structure of the inlet 9 is designed to prevent material from spilling or leaking during the feeding process, ensuring the safety and accuracy of material conveying. The top right side of the conveying pipe 8 is fixedly connected to the bottom of the inlet 9. The rear side of the exhaust pipe 10 is fixedly connected to the front side of the reaction chamber 7. The exhaust pipe 10 is connected to the front side of the reaction chamber 7 and is used to discharge the gas generated in the reaction chamber 7 during the reaction process.

[0038] Working principle: When raw materials enter the feed hopper 3, they pass through the anti-blocking mechanism 4. The power shaft 42 drives the power gear 43 to rotate, and the power gear 43 drives the rotating shaft 45 and the connecting gear 46 to rotate through the gear chain 44. Since the outer side of the multiple moving blocks 48 is meshed with the outer side of the gear chain 44, the rotation of the gear chain 44 causes the moving blocks 48 to slide in the slide hopper 47. The moving blocks 48 then drive the stirring assembly 49 to move. The fixed rod 491 slides with the moving blocks 48, and the contact rod 492 on the outside of the fixed rod 491 also moves accordingly. The contact rod 492 moves continuously in the feed hopper 3, preventing materials from accumulating in the feed hopper 3, thereby achieving the effect of preventing materials from accumulating in the feed hopper 3 and preventing blockage.

[0039] During the operation of the fixing mechanism 5, when it is necessary to disassemble the collection bag 57, the fixing ring 55 is manually rotated. The fixing ring 55 drives the limiting block 56 to slide in the limiting groove on the inner wall. The sliding of the limiting block 56 causes the shrinking column 53 to compress the spring 54. The spring 54 is compressed by force. When the limiting block 56 slides to the slot position, the fixing ring 55 separates from the connecting pipe 52. When it is rotated in the opposite direction to the appropriate position, the spring 54 is released, causing the limiting block 56 to be locked in the limiting groove, thus realizing the fixed connection between the fixing ring 55 and the connecting pipe 52. This achieves the effect of convenient fixed installation and release of the collection bag 57, making it easy to replace or clean the collection bag 57.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
