Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a VOCs purification zeolite rotor device. Background Technology

[0002] The zeolite concentrator rotor is made of ceramic fiber as the base material and coated with hydrophobic zeolite as the adsorbent. It is made into a honeycomb-shaped disc and is the core component of the zeolite concentrator rotor technology. It can effectively adsorb organic solvents in waste gas and achieve a purification efficiency of over 98%. Chinese utility model CN223082534U proposes "a zeolite rotor device for treating organic waste gas". This device improves the utilization rate of the filter module by avoiding the filter module only contacting the gas at the inlet and outlet by setting the gas inlet and outlet radially. By setting the gas to flow along the length of the filter module, the gas flow path is extended, which increases the thoroughness of adsorption of organic matter. However, this device has low installation and removal efficiency of zeolite filter element, which is inconvenient for subsequent replacement of zeolite filter element, thus reducing the efficiency of subsequent equipment maintenance. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a VOCs purification zeolite rotor device, which solves the technical problem that the zeolite rotor core in the prior art has low overall installation and disassembly efficiency, and it is inconvenient for staff to replace it later, which invisibly reduces the subsequent working efficiency of the equipment.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a VOCs purification zeolite rotor device, comprising: Shaft body; A plurality of mounting frames are arranged circumferentially around the outer periphery of the shaft body, and multiple mounting areas are formed on the outer periphery of the shaft body. A zeolite wheel core includes a wheel core body, a first assembly frame, and a second assembly frame. The first assembly frame and the second assembly frame are respectively installed at both ends of the wheel core body. The wheel core body is detachably connected to the mounting frame. The first assembly frame is provided with a limiting component. The fastening mechanism includes a rotating end and a locking block. Rotating ends are provided on both sides of any one of the mounting frames. A locking component is connected to one of the rotating ends. The locking component is locked onto the limiting component and is used to limit the wheel core body.

[0005] In some embodiments, the number of mounting frames is at least three, and the three mounting frames are equidistantly arranged on the outer periphery of the shaft.

[0006] In some embodiments, an auxiliary block is provided between the three mounting frames, the length of which is less than the length of the shaft.

[0007] In some embodiments, a limiting groove is formed at the top of the inner cavity of the mounting frame, and a limiting member is slidably connected within the limiting groove.

[0008] In some embodiments, a plurality of positioning holes are provided at equal intervals on both sides of the front side of the mounting frame.

[0009] In some embodiments, the limiting member includes a limiting block, an extension plate, and a positioning post; two limiting blocks are arranged at the upper ends of the first assembly frame and the second assembly frame, and the limiting blocks are slidably connected in the limiting groove; an extension plate is provided on the surface of the first assembly frame, and a positioning post corresponding to the positioning hole is provided on the extension plate.

[0014] Compared with existing technologies, the VOCs purification zeolite rotor device provided by this utility model, through the setting of a detachable zeolite wheel core and multiple mounting frames arranged circumferentially on the outer periphery of the shaft, and the use of a fastening mechanism to engage and limit the limiting components, achieves a quick-installation and quick-release structure for the zeolite wheel core. Through the cooperation of the engaging and limiting components, the wheel core can be quickly released or locked by simply operating the lever, which greatly shortens maintenance time and improves equipment availability. The synergistic effect of the limiting and engaging components not only prevents the wheel core from shifting or loosening during high-speed rotation, but also avoids sealing failure or airflow short circuit caused by vibration, thus improving structural stability and directly ensuring the uniform distribution and full adsorption of VOCs waste gas when passing through the zeolite wheel core. Since the zeolite wheel core is an independent detachable unit, and the mounting frames form multiple installation areas on the outer periphery of the shaft, users can flexibly configure the number or type of wheel cores according to actual working conditions, such as waste gas concentration and treatment volume. If a wheel core in a certain area fails, there is no need to replace the whole unit, only the corresponding module needs to be replaced, reducing operation and maintenance costs.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figure 1 , Figure 1 This is a schematic diagram of a VOCs purification zeolite rotor device according to an embodiment of the present invention. The VOCs purification zeolite rotor device includes: Shaft 1; A plurality of mounting frames 2 are arranged circumferentially around the outer periphery of the shaft 1, forming multiple mounting areas on the outer periphery of the shaft 1; The zeolite wheel core 3 includes a wheel core body 31, a first assembly frame 32 and a second assembly frame 33. The first assembly frame 32 and the second assembly frame 33 are respectively installed at both ends of the wheel core body 31. The wheel core body 31 is detachably connected to the mounting frame 2. The first assembly frame 32 is provided with a limiting member 34. The fastening mechanism 4 includes a rotating end 41 and a locking block 421. The rotating end 41 is provided on both sides of any mounting frame 2. A locking member 42 is connected to one of the rotating ends 41. The locking member 42 is locked onto the limiting member 34 and is used to limit the wheel core body 31.

[0019] In this embodiment, by setting a detachable zeolite wheel core 3 and multiple mounting frames 2 arranged circumferentially on the outer periphery of the shaft 1, and cooperating with the fastening mechanism 4 to engage and limit the limiting component 34, a quick-installation and quick-release structure for the zeolite wheel core 3 is achieved. Through the cooperation of the engaging component 42 and the limiting component 34, the wheel core can be quickly released or locked by simply operating the lever 423, which greatly shortens maintenance time and improves equipment availability. The limiting component 34 and the engaging component 42 work together to not only prevent the wheel core from shifting or loosening during high-speed rotation, but also avoid sealing failure or airflow short circuit caused by vibration, thus improving structural stability and directly ensuring the uniform distribution and full adsorption of VOCs exhaust gas when passing through the zeolite wheel core 3. Since the zeolite wheel core 3 is an independent detachable unit, and the mounting frames 2 form multiple installation areas on the outer periphery of the shaft 1, users can flexibly configure the number or type of wheel cores according to actual working conditions, such as exhaust gas concentration and processing volume. If a wheel core in a certain area fails, there is no need to replace the whole unit; only the corresponding module needs to be replaced, reducing operation and maintenance costs.

[0020] In one embodiment, please refer to Figure 1 - Figure 6 To facilitate the rapid assembly of the zeolite wheel core 3, the number of mounting frames 2 is at least three. The three mounting frames 2 are equidistantly arranged on the outer periphery of the shaft body 1. An auxiliary block 5 is provided between the three mounting frames 2. The length of the auxiliary block 5 is less than the length of the shaft body 1. A limiting groove 21 is opened at the top of the inner cavity of the mounting frame 2. A limiting component 34 is slidably connected in the limiting groove 21. Multiple positioning holes 22 are equidistantly opened on both sides of the front of the mounting frame 2. The limiting component 34 includes a limiting block 341, an extension plate 342 and a positioning post 343. Two limiting blocks 341 are arranged at the upper end of the first assembly frame 32 and the second assembly frame 33, and the limiting blocks 341 are slidably connected in the limiting groove 21. An extension plate 342 is provided on the surface of the first assembly frame 32. A positioning post 343 corresponding to the positioning hole 22 is provided on the extension plate 342.

[0021] In this embodiment, there are at least three mounting frames 2, arranged equidistantly circumferentially. The three mounting frames 2 ensure uniform force distribution on the zeolite rotor during rotation, preventing eccentric vibration or structural deformation due to insufficient support points. The three mounting frames 2 are evenly distributed at 120° intervals along the outer circumference of the shaft 1, forming a stable triangular support structure. This not only improves overall rigidity but also maintains dynamic balance of the zeolite wheel core 3 during high-speed rotation, reducing mechanical wear. An auxiliary block 5 is added between adjacent mounting frames 2 to enhance the integrity of the outer circumference structure of the shaft 1, preventing relative displacement of the mounting frames 2 due to thermal expansion and contraction or vibration during long-term operation. A limiting groove 21 is formed at the top of the inner cavity of the mounting frame 2. Limiting block 341 provides a guide rail; limiting block 341 is located on the upper end of the first and second assembly frames 33 and slides into the limiting groove 21. During installation or disassembly, it guides the wheel core to slide into / out of the mounting frame 2 along a predetermined path, improving the smoothness of operation. Multiple interfaces are equidistantly opened on both sides of the front of the mounting frame 2 to form a standardized interface; it is located on the extension plate 342 and corresponds one-to-one with the positioning hole 22; this ensures that the depth position of the wheel core body 31 in the mounting frame 2 is consistent, avoiding poor sealing or airflow short circuit due to installation deviation; at the same time, multi-point positioning can effectively prevent the wheel core from rotating or shaking slightly during operation, ensuring the accuracy of the partitioning of the adsorption zone, desorption zone, and cooling zone.

[0022] In one embodiment, please refer to Figure 1 - Figure 3 To facilitate effective positioning of the zeolite filter element, a vertical shaft 344 is installed on the front of the extension plate 342. A locking component 42 is detachably connected to the vertical shaft 344. The rotating end 41 includes a rotating shaft 411 and a connecting frame 412. The rotating shaft 411 is movably connected to both sides of the mounting frame 2. A connecting frame 412 is fixed on the rotating shaft 411. The locking component 42 is connected to the end of the connecting frame 412. The locking component 42 includes a locking block 421. The locking block 421 is connected to the end of the connecting frame 412, and a locking opening 422 is provided on the locking block 421. The locking opening 422 is used to lock onto the vertical shaft 344. A bending block 423 is provided on the side of the locking block 421 facing away from the vertical shaft 344.

[0023] In this embodiment, the engagement port 422 and the vertical shaft 344 form a mechanical quick-connect structure. Locking or unlocking can be achieved simply by aligning the engagement port 422 of the engagement block 421 with the vertical shaft 344 and pressing down or pulling it outwards, without the need for wrenches, screwdrivers, or other tools. The prying block 423 provides the operator with a clear point of force application and a lever fulcrum, requiring only a small torque applied with one hand to complete the engagement / disengagement action. The engagement port 422 wraps around the vertical shaft 344 to form a ring-shaped limit. This is achieved when the zeolite wheel rotates at high speed, typically 2-6 rpm. The speed is r / min, but during long-term continuous operation, even if subjected to airflow impact or vibration, the locking block 421 is not easy to detach on its own. The connecting frame 412 is movably connected to both sides of the mounting frame 2 through the rotating shaft 411, giving the locking part 42 a certain self-adjusting capability. It can compensate for small displacements caused by manufacturing tolerances or thermal deformation, and avoid stress concentration or jamming caused by rigid connection. The prying block 423 is set on the side of the locking block 421 facing away from the vertical axis 344, which conforms to the natural grip and force direction of the human body. It is usually pulled outward, making the operation intuitive and labor-saving, even in the confined space and poor lighting of the equipment. In this case, maintenance personnel can also complete the operation by feel, reducing reliance on vision. The skill requirements for operators are low, and ordinary workers can be competent after simple training, reducing the company's human resource training costs. The vertical shaft 344 and the locking part 42 are detachably connected, which means that the locking part 42 itself can also be replaced separately. If the locking port 422 is worn or the bending block 423 is broken, there is no need to replace the entire assembly frame or wheel core. Only the locking part 42 needs to be replaced to restore the function. The locking mechanism applies a stable and repeatable clamping force to the wheel core to ensure that the first and second assembly frames 33 and the mounting frame 2 fit tightly together, reducing the gas leakage channel.

[0024] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below: When installation is required, inspect the zeolite wheel core 3 to be installed, including the wheel core body 31, the first assembly frame 32, the second assembly frame 33, the limiting block 341, the extension plate 342, the positioning post 343, and the vertical shaft 344, to ensure they are intact. Confirm that the rotating ends 41, connecting brackets 412, and locking blocks 421 on both sides of the target mounting frame 2 are in the open state, i.e., the locking block 421 is not locked on the vertical shaft 344. Pull the block 423 outward to align the zeolite wheel core 3 axially with the opening of the target mounting frame 2. Align the limiting block 341 with the limiting groove 21. Align the two limiting blocks 341 at the upper ends of the first assembly frame 32 and the second assembly frame 33 with the limiting groove 21 at the top of the inner cavity of the mounting frame 2. Gently push the wheel core to allow it to slide smoothly into the mounting frame 2 under the guidance of the limiting groove 21, avoiding tilting or jamming. During the pushing process, the positioning post 343 on the extension plate 342 should be aligned with the mounting frame 2. Continue pushing the positioning holes 22 on both sides of the front of frame 2 until the positioning pin 343 is fully embedded in the positioning hole 22. At this time, the wheel core reaches the preset installation depth and the circumferential position is locked by multiple positioning points to prevent rotational displacement. At this time, the wheel core body 31 is fully embedded in the installation area, and the first and second assembly frames 33 are basically in contact with the end face of the installation frame 2. Hold the lever 423 by hand and rotate or press the locking block 421 inward around the rotating shaft 411 so that the locking opening 422 is aligned and fitted into the vertical shaft 344. When the locking opening 422 completely covers the vertical shaft 344, release the lever 423. The locking block 421 remains locked under its own weight or slight elastic preload. Repeat the operation of the locking part 42 on the other side to ensure that both ends of the wheel core are reliably limited. The installation is complete. Both locking blocks 421 on both sides are locked on the vertical shaft 344. The wheel core cannot be pulled out axially or rotated circumferentially and is tightly fitted with the installation frame 2.

[0025] When disassembly is required, grasp the lever 423 on the back of one side of the locking block 421 and apply force outward to rotate the locking block 421 around the rotating shaft 411, disengaging the locking opening 422 from the vertical shaft 344. Repeat the operation on the other side of the locking block 421 to ensure that both locking parts 42 are released. Grasp the wheel core body 31 or the edge of the mounting frame with both hands and pull it out smoothly along the axial direction. During the pulling process, the limiting block 341 slides along the limiting groove 21 to provide guidance and prevent the wheel core from shaking or scratching the inner wall of the mounting frame 2. The positioning pin 343 simultaneously emerges from the positioning hole 22. The device can be withdrawn without any jamming. After the zeolite wheel core is completely removed, it can be cleaned, replaced, or inspected. At the same time, it can check whether the locking part 42, vertical shaft 344, limit groove 21, and other components are worn or deformed. If necessary, the vulnerable parts can be replaced. When the device can periodically replace or regenerate the zeolite wheel core 3, the replacement of a single module can be completed within 30 minutes. When the adsorption efficiency of a certain area decreases, only the corresponding wheel core needs to be replaced, without affecting the operation of other areas. According to the changes in VOCs composition, different types of zeolite wheel cores 3 can be replaced, such as hydrophobic type and high-silica type, without modifying the main unit structure.

[0026] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
