Description

Technical Field

[0001] The utility model relates to the technical field of VOC treatment, in particular to a VOC treatment device. Background Art

[0002] Dry filter devices play an important role in VOC treatment. They are usually used to remove particulate matter and other harmful substances in exhaust gas, providing a purer exhaust gas source for subsequent VOCs treatment processes. In the VOC treatment process, organic waste gas first passes through the collection system to enter the pretreatment stage. As one of the pretreatment equipment, dry filter devices can effectively remove impurities such as paint dew, acidic substances and particulate matter in the exhaust gas. If these impurities directly enter the subsequent VOCs treatment equipment, they may cause damage to the equipment or reduce the treatment efficiency.

[0003] Existing dry filtering devices usually use a pull-out filter plate for easy replacement. However, in the process of replacing the filter plate, due to the existence of assembly errors, the size of the slide rail is often designed to be relatively large to accommodate the product errors of different filter plates. Although this design solves the assembly problem to a certain extent, it brings some adverse effects during actual use. Since the air flow rate inside the filter is high, it directly impacts the filter plate, resulting in friction noise between the filter plate and the slide rail, which not only affects the smooth operation of the equipment, but may also reduce the installation firmness of the filter plate, thereby affecting the filtering effect and equipment life. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a VOC treatment device to solve the technical problem that the air flow rate inside the filter is high, directly impacting the filter plate, causing friction noise between the filter plate and the slide rail.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a VOC treatment device, comprising a filter device body, a cavity is formed inside the filter device body, slide rails are arranged on the upper and lower sides of the cavity, a filter plate is slidably connected inside the slide rail, and a pressing assembly is arranged on the top of the filter plate;

[0006] The pressing assembly comprises an empty slot, a movable plate is arranged inside the empty slot, pressing blocks are arranged on both sides of the bottom end of the movable plate, and a screw rod is connected to the internal thread of the pressing block.

[0007] By adopting the above technical solution, the pressing assembly effectively prevents the filter plate from vibrating during operation. Due to the inclined pressing action of the pressing block on the movable plate and the pressure applied by the movable plate to the slide rail through the pressing sheet, the filter plate is firmly held in the slide rail, thereby reducing the vibration caused by the passage of high-speed airflow.

[0008] Furthermore, the screw rod is provided with two sets of threads, and the two sets of threads are arranged in a mirror image along the length center line of the screw rod, and an outer door is rotatably provided on the outer side of the filter device body.

[0009] By adopting the above technical solution, the two pressing blocks can move simultaneously and towards each other when the screw rotates. This design simplifies the adjustment process and ensures that the filter plate can be subjected to uniform and stable pressing during installation, thereby improving the installation firmness and stability of the filter plate.

[0010] Furthermore, the pressing block abuts against the movable plate, and the abutting surfaces are all arranged as inclined structures.

[0011] By adopting the above technical solution, the inclined surface structure abutting design between the pressing block and the movable plate can provide a smooth guiding effect when the pressing block moves. This inclined surface contact makes the pressing force dispersed and uniform, reduces stress concentration, and thus enhances the stability of the structure.

[0012] Furthermore, a pressing piece is provided on the top of the movable plate, the pressing piece is in contact with the inner wall of the slide rail, and the pressing piece is made of rubber.

[0013] By adopting the above technical solution, the rubber pressure piece on the top of the movable plate is in close contact with the inner wall of the slide rail, which effectively increases the friction between the two, thereby preventing the filter plate from shaking or accidentally moving in the slide rail. This stability ensures the efficiency and reliability of the filtration process.

[0014] Furthermore, a mounting block is detachably provided on the upper side of one side of the filter plate, and the mounting block is opposite to the empty slot.

[0015] By adopting the above technical solution, the detachable mounting block design on the upper side of the filter plate is convenient for corresponding to the empty slot in the pressing assembly. This structure simplifies the installation and disassembly process of the pressing assembly.

[0016] Furthermore, the materials of the pressing block and the movable plate are both stainless steel, and limiting plates are provided on both sides of the movable plate.

[0017] By adopting the above technical solution, it is ensured that these two components have excellent corrosion resistance and mechanical strength, so that they can operate stably for a long time in harsh working environments.

[0018] Furthermore, one end of the screw rod passes through the filter plate and is fixedly connected with a handle.

[0019] By adopting the above technical solution, this design allows the operator to easily rotate the screw rod through the handle, and the handle provides a good grip point, reducing the difficulty of operation and the force required.

[0020] Furthermore, a buffer mechanism is provided on one side of the filter plate, and the buffer mechanism comprises a card slot, and a card is provided inside the card slot.

[0021] By adopting the above technical solution, a certain buffering effect can be provided when the filter plate is impacted. When the filter plate is under pressure due to high-speed airflow or other reasons, the card in the card slot can absorb part of the energy, thereby reducing the vibration and deformation of the filter plate.

[0022] Furthermore, the cross section of the slot is a "C"-shaped structure, and the slot is fixedly connected to the filter plate.

[0023] By adopting the above technical solution, the card can be firmly engaged in the card slot. This structure effectively limits the movement range of the card to prevent it from accidentally falling off or shifting during use, thereby ensuring the stability and reliability of the buffer mechanism.

[0024] Furthermore, the card abuts against the inner wall of the cavity, and the material of the card is rubber.

[0025] By adopting the above technical solution, the abutment design between the card and the inner wall of the cavity, combined with its rubber material, can provide good sealing and buffering effect when the filter plate is installed. The rubber card has a certain elasticity and deformation ability, which can adapt to the slight unevenness of the inner wall of the cavity, ensuring a close fit between the filter plate and the cavity to prevent gas leakage.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model uses a pressing component, which applies an effective pressing force to the slide rail to prevent the filter plate from vibrating during operation. This stable pressing action ensures that the filter plate can remain fixed when high-speed airflow passes through, reducing performance degradation or damage caused by vibration. At the same time, the pressing component also prevents friction noise between the filter plate and the slide rail. Since the filter plate is firmly pressed against the slide rail, the friction between the two is effectively reduced, thereby reducing the noise level, improving the working environment, and helping to extend the service life of the filter device;

[0028] 2. The utility model provides a buffer mechanism, the design of which can effectively absorb and disperse the impact and vibration energy received by the filter plate, and through the cooperation of the card slot and the card, reduce vibration transmission and noise generation. At the same time, the buffer mechanism also enhances the structural stability of the filter plate. Its existence prevents the filter plate from being deformed or damaged due to long-term impact, thereby extending the service life of the filter plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A VOC treatment device, such as Figure 1-Figure 4 As shown, it comprises a filter device body 1, a cavity 3 is formed inside the filter device body 1, slide rails 4 are arranged on both upper and lower sides of the cavity 3, a filter plate 5 is slidably connected inside the slide rail 4, and a pressing assembly 6 is arranged on the top of the filter plate 5;

[0038] The pressing assembly 6 includes a hollow groove 601, in which a movable plate 602 is arranged, and pressing blocks 604 are arranged on both sides of the bottom end of the movable plate 602. The internal threads of the pressing blocks 604 are connected with screw rods 605. The pressing assembly 6 effectively prevents the filter plate 5 from vibrating during operation. Due to the inclined pressing action of the pressing blocks 604 on the movable plate 602 and the pressure applied by the movable plate 602 to the slide rail 4 through the pressing sheet 603, the filter plate 5 is firmly retained in the slide rail 4, thereby reducing the vibration caused by the passage of high-speed airflow. At the same time, the pressing assembly 6 also prevents the friction noise between the filter plate 5 and the slide rail 4. Due to the stable installation of the filter plate 5 and the close contact between the pressing sheet 603 and the inner wall of the slide rail 4, the filter plate will not generate direct friction with the slide rail 4 during operation, thereby significantly reducing the generation of noise.

[0039] See also Figure 1 , Figure 3 , Figure 4 Two sets of threads are arranged on the screw rod 605, and the two sets of threads are arranged in a mirror image along the length center line of the screw rod 605. An outer door 2 is rotatably arranged on the outer side of the filter device body 1, so that when the screw rod 605 rotates, the two pressure blocks 604 can move simultaneously and towards each other. This design simplifies the adjustment process and ensures that the filter plate 5 can be subjected to uniform and stable pressure during installation, thereby improving the installation firmness and stability of the filter plate 5. At the same time, the outer door 2 arranged on the outer side of the filter device body 1 facilitates the operator to install and replace the filter plate. By opening the outer door, the operator can easily access the slide rail 4 and the filter plate 5, thereby performing necessary maintenance and replacement work.

[0040] See also Figure 3 , Figure 4 The pressure block 604 is in contact with the movable plate 602, and the contact surfaces are both inclined structures. The inclined structure abutting design of the pressure block 604 and the movable plate 602 can provide a smooth guiding effect when the pressure block moves. This inclined contact makes the pressure dispersed and uniform, reduces stress concentration, and thus enhances the stability of the structure. At the same time, the inclined structure also helps to reduce the friction resistance between the pressure block 604 and the movable plate 602. When the pressure block 604 moves to adjust the position of the movable plate 602, the sliding of the inclined contact surface is smoother and the required operating force is also smaller, thereby improving the accuracy and convenience of adjustment.

[0041] See also Figure 3 , Figure 4 A pressing piece 603 is provided on the top of the movable plate 602, and the pressing piece 603 abuts against the inner wall of the slide rail 4. The pressing piece 603 is made of rubber. The rubber pressing piece 603 on the top of the movable plate 602 is in close contact with the inner wall of the slide rail 4, which effectively increases the friction between the two, thereby preventing the filter plate 5 from shaking or accidentally moving in the slide rail. This stability ensures the efficiency and reliability of the filtering process. At the same time, the pressing piece 603 made of rubber has good elasticity and buffering properties, can absorb part of the vibration and impact energy, and further reduces the noise and vibration generated by the filter plate 5 during operation.

[0042] See also Figure 3 , Figure 4A mounting block 608 is detachably provided on the upper side of one side of the filter plate 5, and the mounting block 608 is opposite to the empty slot 601. The design of the detachable mounting block 608 on the upper side of the filter plate 5 is convenient for corresponding to the empty slot 601 in the pressing assembly 6. This structure simplifies the installation and disassembly process of the pressing assembly 6. At the same time, the detachability of the mounting block 608 makes the maintenance and replacement of the filter plate 5 more flexible and convenient. When the filter plate 5 needs to be cleaned, repaired or replaced, only the mounting block 608 needs to be removed to easily take out the movable plate 602, thereby reducing the maintenance cost and difficulty.

[0043] See also Figure 3 , Figure 4 The materials of the pressing block 604 and the movable plate 602 are both stainless steel, and limiting plates 607 are arranged on both sides of the movable plate 602, ensuring that the two components have excellent corrosion resistance and mechanical strength, so that they can operate stably for a long time in harsh working environments. At the same time, the limiting plates 607 arranged on both sides of the movable plate 602 effectively limit the moving range of the movable plate 602, preventing it from being offset or excessively moved during the adjustment process, and ensuring the accuracy and reliability of the pressing effect.

[0044] See also Figure 3 , Figure 4 One end of the screw rod 605 passes through the filter plate 5 and is fixedly connected with a handle 606. This design allows the operator to easily rotate the screw rod 605 through the handle 606. The handle 606 provides a good gripping point, reducing the difficulty and force required for operation. At the same time, the fixed connection between the handle 606 and the screw rod 605 ensures the stability and reliability of the rotation. During operation, the handle 606 will not loosen or fall off, thereby avoiding accidents or damages caused by improper operation.

[0045] Embodiment 2:

[0046] See also Figure 3 , Figure 4 A buffer mechanism 7 is provided on one side of the filter plate 5, and the buffer mechanism 7 includes a card slot 701. A card 702 is provided inside the card slot 701 to provide a certain buffering effect when the filter plate 5 is impacted. When the filter plate 5 is subjected to pressure due to high-speed airflow or other reasons, the card 702 can absorb part of the energy in the card slot 701, thereby reducing the vibration and deformation of the filter plate 5. At the same time, the card slot 701 and the card 702 are engaged to ensure the stability and reliability of the filter plate 5 during the buffering process.

[0047] See also Figure 3 , Figure 4The cross section of the card slot 701 is a "C"-shaped structure. The card slot 701 is fixedly connected to the filter plate 5, so that the card 702 can be firmly engaged in the card slot 701. This structure effectively limits the movement range of the card 702 to prevent it from accidentally falling off or shifting during use, thereby ensuring the stability and reliability of the buffer mechanism 7. At the same time, the fixed connection between the card slot 701 and the filter plate 5 further enhances the structural strength between the buffer mechanism 7 and the filter plate 5. This tight connection ensures that when the filter plate 5 is impacted or pressurized, the buffer mechanism 7 can effectively absorb and disperse energy, reduce the vibration and deformation of the filter plate, thereby protecting the filter plate 5 and the entire filter device from damage.

[0048] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The card 702 is in contact with the inner wall of the cavity 3. The material of the card 702 is rubber. The contact design between the card 702 and the inner wall of the cavity 3, combined with its rubber material, can provide good sealing and buffering effects when the filter plate 5 is installed. The rubber card 702 has certain elasticity and deformation ability, which can adapt to the slight unevenness of the inner wall of the cavity 3, ensure the close fit between the filter plate 5 and the cavity 3, and prevent gas leakage. At the same time, the soft nature of the rubber card 702 reduces the possible scratches or damage to the inner wall of the cavity 3 during the installation process.

[0049] The implementation principle of the utility model is as follows: first, open the outer door 2, slide the filter plate 5 into the cavity 3 through the slide rail 4, until the card 702 abuts against the inner wall of the cavity 3, then turn the handle 606 to drive the screw rod 605 to rotate and threadedly connect with the two pressing blocks 604, and use two sets of mirror threads to prompt the pressing blocks 604 to move to opposite positions. At this time, the pressing blocks 604 press the movable plate 602 with an inclined surface, prompting the movable plate 602 to move upward, until the pressing sheet 603 abuts against the inner wall of the slide rail 4, and the installation of the filter plate 5 is completed. After that, the outer door is closed;

[0050] When the dry filtering device is used, a high-speed airflow flows through the filter plate 5 through the cavity 3. The pressing component 6 exerts an effective pressing force on the slide rail 4 to prevent the filter plate 5 from vibrating during operation and prevent friction noise between the filter plate 5 and the slide rail 4, thereby reducing the noise generated by the dry filtering device.

[0051] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0052] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
