Description

Technical Field

[0001] This utility model belongs to the field of odor treatment technology in rubber production, and specifically relates to an odor treatment device for rubber production. Background Technology

[0002] The odorous waste gas generated during rubber production mainly originates from multiple stages and various chemical substances. During the rubber refining stage, operations such as raw rubber plasticizing and mixing cause the organic matter in the rubber to volatilize, producing the odor of aromatic hydrocarbons such as benzene, toluene, and xylene. At the same time, there may also be odors from aliphatic hydrocarbons and sulfur-containing compounds such as hydrogen sulfide. During the vulcanization process, sulfur undergoes a cross-linking reaction with rubber, releasing a large amount of sulfur-containing compounds with odors, such as sulfur dioxide, mercaptans, and thioethers. These substances have strong pungent and unpleasant odors. In addition, various additives used in rubber production, such as antioxidants and accelerators, may also decompose or volatilize during processing, producing substances with special odors such as amines and phenols. Together, these factors constitute the complex and unpleasant odor in the waste gas from rubber production.

[0003] Currently, odors generated during rubber production are typically treated using appropriate purification devices. Chinese patent CN212492207U discloses an odor treatment device for rubber mat production. This device includes a base, a column fixed to the base, a smoke collection hood fixed to the column, a dustproof net fixed to the inner wall of the smoke collection hood, an exhaust pipe embedded in the smoke collection hood, a box fixed to the base, a box cover fixed to the box, and the other end of the exhaust pipe embedded in the box cover. A fan, a vortex fan type, is fixed to the base, providing strong suction and high stability. The fan's inlet is embedded in the box. Through the fan's suction effect, odorous gases can pass through the smoke collection hood into the exhaust pipe and then into the box. After passing through two filters, the odors are prevented from harming the human body. The dustproof net filters dust, preventing it from clogging the filter, while the dust collection box collects any falling dust.

[0004] In actual operation, the activated carbon filter inside the device inevitably needs to be cleaned and replaced after prolonged use. However, the current device has significant shortcomings in this regard. Its structural design makes it difficult to quickly replace the activated carbon filter. In practice, each replacement of the activated carbon filter takes a lot of time, seriously affecting work efficiency. Moreover, the device cannot perform purification treatment simultaneously during the replacement of the activated carbon filter, causing the treatment of exhaust gas odor to be interrupted and the gas to be unable to be effectively treated. This situation indicates that the device cannot meet the requirements for continuous and uninterrupted exhaust gas odor treatment, which not only reduces treatment efficiency but may also have adverse effects on the surrounding environment. Therefore, it is urgent to carry out targeted improvement design of the device to enhance its operational stability and treatment efficiency, and achieve efficient and continuous treatment of exhaust gas odor.

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an odor treatment device for rubber production, so as to solve the problem of inconvenient and quick replacement of activated carbon filter screen during the application of the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An odor treatment device for rubber production includes a base, with legs fixedly installed at the four corners of the bottom of the base, and casters rotatably connected to the bottom of the legs. A fixed seat is fixedly installed in the middle of the top of the base, and an installation mechanism is fixedly installed on the outside of the fixed seat. A purification mechanism is installed on the inside of the installation mechanism.

[0008] The installation mechanism includes a circular base, which is fixedly installed on the top of a fixed base. A frame is fixedly installed on the outer side of the circular base, and an adjustment component is fixedly installed on the inner side of the frame. Sealing caps are fixedly installed at both ends of the inner side of the adjustment component, and connecting hoses are fixedly installed on the outer side of the sealing caps. The purification mechanism is disposed between the inner sides of the sealing caps.

[0009] As a preferred technical solution, a mounting base is fixedly installed at one end of the top rear side of the base, and a suction fan is fixedly installed on the top of the mounting base. The input end of the suction fan is connected to the connecting hose located at the bottom.

[0010] As a preferred technical solution, the adjustment component includes a vertical rail, which is fixedly installed on the inner side of the frame. A first motor is fixedly installed on the top of the vertical rail. The output end of the first motor is fixedly connected to a lead screw through the vertical rail. The lead screw is rotatably connected to the inside of the vertical rail. Both ends of the outer surface of the lead screw are threadedly connected to movable blocks. The sealing cover is fixedly connected to the inner side of the movable blocks.

[0011] As a preferred technical solution, the purification mechanism includes a mounting plate, which is fixedly connected to the top of the frame. A second motor is fixedly connected to the top of the mounting plate. A rotating shaft is fixedly installed through the mounting plate at the output end of the second motor. A fixing block is fixedly installed in the middle of the rotating shaft. Fixing rods are fixedly installed on both sides of the fixing block. A purification component is fixedly connected to the outer end of the fixing rod.

[0012] As a preferred technical solution, the purification component includes an annular seat, with grooves evenly spaced on the inner side of the annular seat. A slider is slidably connected inside the groove, and an installation sleeve is fixedly connected to the inner side of the slider. An activated carbon purification core is fixedly installed inside the installation sleeve. The installation sleeve near the vertical rail is positioned between two sealing covers, and both ends of the installation sleeve are inserted into the inside of the sealing covers.

[0013] As a preferred technical solution, a fixing plate is fixedly connected to the outer side of the tripod, and an anti-slip screw is threadedly connected to the outer side of the fixing plate.

[0014] As a preferred technical solution, the anti-slip screw is configured as a hand-tightening screw, the bottom of the anti-slip screw is provided with an anti-slip base plate, and the outer sides of the base and the fixing seat are both configured as arc-shaped.

[0015] In summary, the present invention has the following main advantages:

[0016] First, the installation mechanism of this device greatly simplifies equipment maintenance and waste gas purification processes. In use, the installation sleeve of the purification mechanism is placed between the two sealing covers, the first motor is started, and the motor drives the lead screw to rotate. Because the threads at both ends of the lead screw are reversed, the movable block is driven to slide, which drives the sealing cover to cover both ends of the installation sleeve. The waste gas pipeline is connected and the suction fan is started. The waste gas enters the sleeve and is purified by the activated carbon purification core, showing excellent purification performance. When the activated carbon purification core needs to be replaced, the first motor is started again, and the lead screw drives the movable block and sealing cover to move outward, so that the purification mechanism can be removed. The maintenance process is easy and convenient, which effectively improves the maintainability and efficiency of the device.

[0017] Secondly, the design of the purification mechanism of this device allows for continuous purification of waste gas while facilitating the replacement of the activated carbon purification core. During core replacement, the first motor is started to cause the lead screw to separate the sealing cover. Then, the second motor is started, which drives the rotating shaft and fixing block to rotate, causing the purification component at the outer end of the fixing rod to rotate, thus switching the position of the purification component. Next, the first and second motors are operated again to move the replaced purification component to the space between the sealing covers and cover it with the sealing cover. The removed component, lacking a sealing cover, can be directly pulled out from the annular groove to install the sleeve for core replacement. The slider inside the groove ensures stable installation. In this way, the device can continue purifying even during core replacement, significantly improving overall ease of use and purification efficiency. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 4 An odor treatment device for rubber production according to this embodiment includes a base 1, with a bracket 2 fixedly installed at each of the four corners of the bottom of the base 1. A caster wheel 3 is rotatably connected to the bottom of the bracket 2. A fixed seat 4 is fixedly installed in the middle of the top of the base 1. An installation mechanism 5 is fixedly installed on the outside of the fixed seat 4. A purification mechanism 6 is installed on the inside of the installation mechanism 5. The purification mechanism 6 is located inside the installation mechanism 5.

[0025] The mounting mechanism 5 includes a circular base 51, which is fixedly mounted on the top of the fixed base 4. A frame 52 is fixedly mounted on the outer side of the circular base 51, and an adjusting component 53 is fixedly mounted on the inner side of the frame 52. Sealing covers 54 are fixedly mounted on both ends of the inner side of the adjusting component 53, and connecting hoses 55 are fixedly mounted on the outer side of the sealing covers 54. The purification mechanism 6 is located between the inner sides of the sealing covers 54. The device can be flexibly moved to the rubber production waste gas emission point by the universal wheels 3 rotatably connected to the bottom of the foot bracket 2. The fixed base 4 on the top of the base 1 provides stable support for the overall structure. Then, the mounting mechanism 5 takes effect. The circular base 51 is fixed on the top of the fixed base 4, providing a mounting base for the frame 52. The first motor 532 in the adjusting component 53 is started, and the motor drives the lead screw 53. 3. Rotating inside the frame 52, the screw 533 has opposite threads at both ends, which drives the movable block 534 connected to it to slide. The movable block 534 moves the sealing cover 54, and after placing the installation sleeve 664 of the purification mechanism 6 between the two sealing covers 54, the adjustment component 53 is operated again to make the sealing cover 54 cover both ends of the installation sleeve 664. Then, the exhaust pipe is connected through the connecting hose 55. At this time, the suction fan 8 in the purification mechanism 6 is started. The exhaust gas is sucked into the installation sleeve 664 through the connecting hose 55 under negative pressure. The activated carbon purification core 665 in the purification mechanism 6 is used to purify and adsorb the exhaust gas and remove odors. In the whole process, the installation mechanism 5 and the purification mechanism 6 work together to achieve effective treatment of odors from rubber production exhaust gas.

[0026] refer to Figures 1-3 A mounting base 7 is fixedly installed at the rear top of the base 1. A suction fan 8 is fixedly installed on the top of the mounting base 7. The input end of the suction fan 8 is connected to the connecting hose 55 located at the bottom. The mounting base 7 is fixed to the rear top of the base 1, providing a stable support foundation for the suction fan 8. When the entire odor treatment device starts working, after the suction fan 8 starts, its internal motor drives the impeller to rotate at high speed, creating a negative pressure environment inside the suction fan 8. Since the input end of the suction fan 8 is connected to the connecting hose 55 at the bottom, this negative pressure is transmitted through the connecting hose 55 to the interior of the sealing cover 54 and the mounting sleeve 664 of the purification mechanism 6. Under the action of this negative pressure suction, the odorous waste gas generated during the rubber production process is quickly sucked into the suction fan 8 through the connecting hose 55. Then the waste gas enters the installation sleeve 664 of the purification mechanism 6 and comes into full contact with the activated carbon purification core 665 to complete the odor purification and adsorption process. Finally, the odor of the rubber production waste gas is efficiently treated, ensuring that the waste gas meets the emission standards and reducing environmental pollution.

[0027] refer to Figure 2The adjusting component 53 includes a vertical rail 531, which is fixedly installed inside the frame 52. A first motor 532 is fixedly installed on the top of the vertical rail 531. The output end of the first motor 532 passes through the vertical rail 531 and is fixedly connected to a lead screw 533. The lead screw 533 is rotatably connected inside the vertical rail 531. Both ends of the outer surface of the lead screw 533 are threaded with movable blocks 534. A sealing cover 54 is fixedly connected to the inside of the movable blocks 534. By setting the adjusting component 53, the motor can drive the lead screw 533 to move the movable blocks 534 during use, thereby opening and closing the sealing cover 54. When it is necessary to adjust the position of the sealing cover 54, the first motor 532 on the top of the vertical rail 531 is started, and its output end drives the lead screw 533 to rotate inside the vertical rail 531. Since both ends of the lead screw 533 are threadedly connected to the movable blocks 534, and the threads at both ends of the lead screw 533 rotate in opposite directions, when the lead screw 533 rotates, the movable blocks 534 at both ends will move in opposite directions along the lead screw 533. The sealing cover 54 is fixedly connected to the inner side of the movable block 534, so the movement of the movable block 534 will drive the sealing cover 54 to move synchronously. To close the sealing cover 54, the first motor 532 drives the lead screw 533 to rotate, causing the movable blocks 534 to move in opposite directions until the sealing cover 54 covers both ends of the mounting sleeve 664 of the purification mechanism 6; to open the sealing cover 54, the first motor 532 rotates the lead screw 533 in the opposite direction, the movable blocks 534 move in the opposite direction, and the sealing cover 54 opens accordingly, facilitating the installation, disassembly, or replacement of the purification mechanism 6.

[0028] refer to Figures 1-4The purification mechanism 6 includes a mounting plate 61, which is fixedly connected to the top of the frame 52. A second motor 62 is fixedly connected to the top of the mounting plate 61. The output end of the second motor 62 passes through the mounting plate 61 and is fixedly mounted with a rotating shaft 63. A fixing block 64 is fixedly mounted in the middle of the rotating shaft 63. Fixing rods 65 are fixedly mounted on both sides of the fixing block 64. A purification component 66 is fixedly connected to the outer end of the fixing rods 65. The purification component 66 includes an annular seat 661. The inner side of the annular seat 661 is provided with grooves 662 at equal intervals. The device has an internal sliding connection with a slider 663. An installation sleeve 664 is fixedly connected to the inner side of the slider 663. An activated carbon purification core 665 is fixedly installed inside the installation sleeve 664. The installation sleeve 664, located near the vertical rail 531, is positioned between two sealing covers 54. Both ends of the installation sleeve 664 are inserted into the sealing covers 54. When the device is opened, the installation plate 61 is fixed to the top of the frame 52, providing support for the overall structure. The second motor 62 is started, and its output drives the rotating shaft 63, which passes through the installation plate 61, to rotate. The fixed block 64 in the middle rotates accordingly, which in turn drives the fixed rods 65 on both sides and the purification components 66 at their outer ends to rotate synchronously. During the purification process, the mounting sleeve 664 on the side near the vertical rail 531 is positioned between the two sealing covers 54, with both ends inserted into the sealing covers 54 to ensure a tight seal. When the suction fan 8 starts and generates suction, the exhaust gas enters the mounting sleeve 664 through the connecting hose 55. The activated carbon purification core 665 inside uses its own adsorption properties to adsorb and purify the odor components in the rubber production exhaust gas, thereby achieving the purification of the exhaust gas. When the activated carbon purification core 665 needs to be replaced, the second motor 62 is restarted to rotate the purification component 66, turning out the used purification component 66 and allowing the spare purification component 66 to rotate between the sealing covers 54 to maintain the continuity of exhaust gas purification. At the same time, the mounting sleeve 664 is slidably connected to the groove 662 of the annular seat 661 through the inner slider 663, which not only ensures the stability of the mounting sleeve 664, but also makes it easy to remove it from the annular seat 661 when replacing it, thus improving the operation convenience and maintenance efficiency of the purification mechanism 6.

[0029] refer to Figures 1-3A fixing plate 9 is fixedly connected to the outer side of the stand 2. An anti-slip screw 10 is threadedly connected to the outer side of the fixing plate 9. The anti-slip screw 10 is a hand-tightening screw. An anti-slip base plate 11 is provided at the bottom of the anti-slip screw 10. The outer sides of both the base 1 and the fixing seat 4 are arc-shaped. The anti-slip design at the stand 2, together with the overall structural design, ensures the stable operation of the device. The fixing plate 9 on the outer side of the stand 2 provides the installation base for the anti-slip screw 10. When the device is moved to the designated position, the anti-slip screw 10 is turned downwards by hand-tightening it. Because it is a hand-tightening screw, the operation is convenient. The anti-slip base plate 11 connected to the bottom of the screw... As the device approaches the ground, the screw is continuously turned, causing the anti-slip base plate 11 to come into close contact with the ground and generate significant friction. This increases the friction between the device and the ground, preventing displacement due to external forces or vibrations during operation and ensuring stable treatment of exhaust gas and odors. Furthermore, the outer sides of the base 1 and the fixed seat 4 are rounded, which reduces sharp edges and corners, lowering safety hazards. On the other hand, the rounded structure is more mechanically stable, effectively distributing the weight of the device and the stress generated during operation, enhancing the overall stability of the device, and further ensuring the smooth operation of the purification process.

[0030] Operating principle and advantages: This device is equipped with a scientific and reasonable installation mechanism 5, which greatly enhances the convenience of maintenance in actual use. In the initial stage of device operation, the installation sleeve 664 of the purification mechanism 6 is accurately placed between the two sealing covers 54, and then the first motor 532 is started. The motor drives the lead screw 533 to rotate stably inside the frame 52 through the transmission device. Since the threads at both ends of the lead screw 533 are turned in opposite directions, it can effectively drive the movable block 534 to slide back and forth along the predetermined track during rotation. As the movable block 534 moves, the sealing cover 54 connected to it can tightly cover both ends of the installation sleeve 664, completing the initial installation and sealing work of the equipment.

[0031] In the waste gas treatment process, after the sealing cover 54 successfully covers both ends of the installation sleeve 664, the device is reliably connected to the waste gas pipeline through the connecting hose 55. Then, the suction fan 8 is started. Under the negative pressure of the suction fan 8, the waste gas is quickly sucked into the installation sleeve 664 and comes into full contact with the activated carbon purification core 665, thereby achieving a highly efficient purification and adsorption process and ensuring that the device has excellent adsorption and purification performance.

[0032] When the activated carbon purification core 665 needs to be replaced, the operation process is simple and easy. The first motor 532 is restarted, and the lead screw 533 drives the movable block 534 to move outward under the drive of the motor, thereby separating the sealing cover 54 from the installation sleeve 664. At this time, the purification mechanism 6 can be removed conveniently and quickly, which greatly facilitates subsequent inspection and maintenance work.

[0033] The carefully designed purification mechanism 6 of this device further enhances the stability and efficiency of equipment operation, realizing continuous waste gas purification treatment. When the activated carbon purification core 665 needs to be replaced, the first motor 532 is started first, and the lead screw 533 rotates to drive the movable block 534 to move, thereby separating the sealing covers 54 from each other, creating conditions for subsequent operations. Then, the second motor 62 is started, and the output shaft of the motor drives the rotating shaft 63 to rotate smoothly. The rotation of the rotating shaft 63 drives the fixed block 64 to rotate synchronously. Under the drive of the fixed block 64, the purification component 66 at the outer end of the fixed rod 65 moves in a circular motion around the central axis, realizing the position switching of the purification component 66. During this process, the mounting sleeve 664, which was originally located between the two sealing covers 54, is successfully moved out, while another set of purification components 66, which was previously located on the outside, is precisely moved between the sealing covers 54.

[0034] At this time, the first motor 532 is started again, and the lead screw 533 drives the movable block 534 to move the sealing cover 54 outward, providing space for the installation of the new purification component 66. Then the second motor 62 is started to drive the installation sleeve 664, which has been replaced with the activated carbon purification core 665, to the space between the sealing covers 54. Then the first motor 532 controls the sealing cover 54 to cover both ends of the installation sleeve 664, and the exhaust gas purification work is quickly restored.

[0035] Since the top sealing cap 54 of the removed purification component 66 has been removed, the mounting sleeve 664 with the activated carbon purification core 665 can be directly pulled out from the inside of the annular groove for quick replacement. It is worth mentioning that the slider 663 inside the groove 662 can effectively assist the mounting sleeve 664 in being stably placed inside the annular seat 661, ensuring the stability of the purification component 66 during installation and operation, and further improving the overall ease of use of this device.

[0036] Through this unique purification mechanism 6 design, even during the replacement of the activated carbon purification core 665, the device can still quickly move another set of purification components 66 to the inside of the sealing cover 54, achieving continuous and uninterrupted waste gas purification treatment, which greatly improves the overall efficiency of the device and meets the needs of industrial production for efficient and stable waste gas treatment.
