[0024] The present invention will be further described below with reference to the embodiments.
[0025] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0026] Please see Figure 1-7This utility model provides an activated carbon purification device, including an exhaust pipe 1. A filter mechanism 4 is installed inside the exhaust pipe 1. The filter mechanism 4 includes a placement frame 402. An air inlet filter 405 is installed on the inner bottom side of the placement frame 402. A limiting ring 403 is fixedly connected to the inner wall of the exhaust pipe 1 at the bottom of the placement frame 402, and the limiting ring 403 abuts against the surface of the placement frame 402. An activated carbon bag 404 is placed inside the placement frame 402. A pull plate 401 is slidably connected to one side of the placement frame 402, and a sliding rod 40 is fixedly connected to the bottom of the pull plate 401. 7. The slide bar 407 is slidably connected to the placement frame 402, and a locking spring 406 is clamped between the slide bar 407 and the placement frame 402. A locking tongue 408 is fixedly connected to the top of the pull plate 401 and is slidably connected to the placement frame 402. A locking groove 409 is provided inside the exhaust pipe 1 at the corresponding position of the locking tongue 408, and the locking groove 409 is engaged with the locking tongue 408. A flow pipe 2 is fixedly connected to the bottom of the exhaust pipe 1. A cleaning mechanism 5 is provided inside the flow pipe 2. A set of limiting mechanisms 7 is provided between the cleaning mechanism 5 and the flow pipe 2. An inlet is provided on one side of the flow pipe 2. A sealing mechanism 6 is provided between the gas mechanism 3, the filter mechanism 4, and the exhaust pipe 1. The gas, after being filtered by the cleaning device, then passes through the intake filter 405 into the exhaust pipe 1. The activated carbon in the activated carbon bag 404 further filters the gas, removing harmful substances and fine impurities. After a period of use, pulling down the pull plate 401 moves the locking tongue 408 out of the lock groove 409, allowing the placement frame 402 to be removed and the activated carbon bag 404 inside to be replaced, preventing damage after prolonged use. The failure of the activated carbon bag 404 affects the filtration effect. After replacement, push the placement frame 402 into the exhaust pipe 1. The locking tongue 408 is squeezed by the exhaust pipe 1, which drives the pull plate 401 and the slide rod 407 to move, and causes the locking spring 406 to contract. When the locking tongue 408 corresponds to the locking groove 409, the locking spring 406 drives the locking tongue 408 to reset through the slide rod 407 and the pull plate 401, so that the locking tongue 408 and the locking groove 409 are engaged, thereby realizing the installation and fixation of the placement frame 402. This facilitates the quick replacement of the activated carbon bag 404 and makes it more convenient to use.
[0027] Specifically, such as Figure 1 and Figure 4 As shown, the pull plate 401 has an "L" shaped cross-section, the top side of the latch 408 has an arc-shaped structure, and the slide bar 407 has an inverted "T" shaped cross-section. The shape of the latch 408 is designed to allow it to automatically retract under force when the frame 402 is installed, and the shape of the slide bar 407 is designed to prevent it from falling off when sliding.
[0028] Specifically, such as Figure 3 and Figure 4As shown, the sealing mechanism 6 includes a fixed ring 601, which is fixedly connected to the exhaust pipe 1. A sealing ring 603 is slidably connected inside the fixed ring 601, and the sealing ring 603 abuts against the surface of the placement frame 402. The bottom of the sealing ring 603 near the pull plate 401 has an arc-shaped structure. A support spring 602 is sandwiched between the sealing ring 603 and the fixed ring 601. When the placement frame 402 moves, it squeezes the sealing ring 603. When the sealing ring 603 moves upward, it causes the support spring 602 to contract. The support spring 602 drives the sealing ring 603 to achieve a reverse force, so that the sealing ring 603 squeezes the placement frame 402. This makes the two ends of the placement frame 402 tightly fit with the limiting ring 403 and the sealing ring 603 respectively to achieve a seal and prevent gas leakage that has not been completely treated.
[0029] Specifically, such as Figure 3 As shown, the cleaning mechanism 5 includes a sealing cover 501, which abuts against the surface of the flow pipe 2. A support rod 503 is fixedly connected to the center of the sealing cover 501. A filter plate 504 is threadedly connected to the top of the support rod 503, which abuts against the inner surface of the flow pipe 2. A sealing ring 502 is fixedly connected to the inner side of the sealing cover 501, which abuts against the bottom surface of the flow pipe 2. When the exhaust gas passes through the flow pipe 2, the filter plate 504 blocks the flocculent matter or large particles in the exhaust gas, preventing the flocculent matter or large particles from adsorbing onto the inner wall of the pipe and clogging the pipe after long-term use. When the sealing cover 501 is removed, the sealing cover 501 drives the filter plate 504 to move via the support rod 503. During the movement of the filter plate 504, the impurities adsorbed on the inner wall of the flow pipe 2 are scraped off. The scraped impurities fall onto the sealing cover 501, thereby cleaning the impurities. The filter screen can also be disassembled and replaced to prevent damage or clogging of the filter screen from affecting the filtration effect.
[0030] Specifically, such as Figure 1 As shown, the air intake mechanism 3 includes an air intake pipe 301, which is fixedly connected to the flow pipe 2. A mounting base 302 is fixedly connected to one end of the air intake pipe 301 away from the flow pipe 2. A sealing gasket 303 is fixedly connected to the side of the mounting base 302 away from the air intake pipe 301. The device is installed at the exhaust port of the machine by bolts on the mounting base 302. The sealing gasket 303 can seal the connection between the device and the chassis to prevent exhaust gas leakage.
[0031] Specifically, such as Figure 5 and Figure 6As shown, the limiting mechanism 7 includes a fixed base 701, which is fixedly connected to the flow pipe 2. A limiting block 702 is fixedly connected to the top of the sealing cover 501. A stop block 703 is slidably connected inside the fixed base 701 at the corresponding position of the limiting block 702, and the stop block 703 and the limiting block 702 mutually limit each other. A pull rod 705 is fixedly connected to the side of the stop block 703 away from the limiting block 702, and the pull rod 705 is slidably connected to the fixed base 701. A limiting spring 704 is clamped between the stop block 703 and the fixed base 701. After a period of use, the two pull rods are pulled to both sides. 705. Pull rod 705 moves stop block 703, allowing sealing cover 501 to be removed. During installation, align limit block 702 on sealing cover 501 with the groove of fixing seat 701 and push it upward. During the movement, limit block 702 presses against stop block 703. The pressure on stop block 703 causes pull rod 705 to move and limit spring 704 to contract. When the larger end of limit block 702 moves above stop block 703, limit spring 704 drives stop block 703 to reset, thereby limiting limit block 702 and limiting the installation of sealing cover 501. The structure is simple and easy to use.
[0032] Specifically, such as Figure 6 As shown, the cross-section of the pull rod 705 is T-shaped, the cross-section of the limiting block 702 is inverted L-shaped, and the top of the limiting block 702 near the stop block 703 is arc-shaped, and the top of the stop block 703 near the limiting block 702 is arc-shaped. The shape of the stop block 703 is designed to facilitate its automatic retraction under force.
[0033] The working principle and usage process of this utility model are as follows: During use, the device is installed at the exhaust port of the machine using bolts on the mounting base 302. The sealing gasket 303 seals the connection between the device and the casing to prevent exhaust gas leakage. Exhaust gas enters the flow pipe 2 through the inlet pipe 301. As the exhaust gas passes through the flow pipe 2, the filter plate 504 blocks flocculent matter or large particles in the exhaust gas, preventing them from adsorbing onto the inner wall of the pipe and clogging it after prolonged use. After a period of use, the two pull rods 705 are pulled to both sides. The pull rods 705 move the stop block 703, allowing the sealing cover 501 to be removed. The sealing cover 501 moves the filter plate 504 via the support rod 503. During the movement, impurities adsorbed on the inner wall of the flow pipe 2 are scraped off and fall onto the sealing cover 501, thus cleaning the impurities. The filter screen can also be disassembled and replaced to prevent damage or clogging that could affect the filtration effect. After cleaning, the limiting block 702 on the sealing cover 501 is aligned with the groove of the fixing seat 701 and pushed upwards. During movement, the limiting block 702 presses against the stop block 703. The pressure on the stop block 703 causes the pull rod 705 to move and the limiting spring 704 to contract. When the larger end of the limiting block 702 moves above the stop block 703, the limiting spring 704 causes the stop block 703 to reset, thus limiting the position of the limiting block 702 and, consequently, limiting the installation of the sealing cover 501. After being filtered by filter plate 504, the gas passes through intake filter 405 and enters exhaust pipe 1. The activated carbon in activated carbon bag 404 filters the gas again, removing harmful substances and fine impurities. After a period of use, pull down pull plate 401. Pull plate 401 moves lock tongue 408 out of lock groove 409, allowing the placement frame 402 to be removed and the activated carbon bag 404 inside the placement frame 402 to be replaced. This prevents the activated carbon bag 404 from failing and affecting the filtration effect after prolonged use. After replacement, push placement frame 402 into exhaust pipe 1. During the movement, placement frame 402 compresses sealing ring 603. As sealing ring 603 moves upward, it supports... When spring 602 contracts, the supporting spring 602 drives the sealing ring 603 to exert a reverse force, causing the sealing ring 603 to press against the placement frame 402. This ensures that both ends of the placement frame 402 are tightly fitted with the limiting ring 403 and the sealing ring 603 respectively, achieving a seal and preventing leakage of incompletely treated gas. During the installation of the placement frame 402, the locking tongue 408 is compressed by the exhaust pipe 1, causing the pull plate 401 and the slide rod 407 to move, and causing the locking spring 406 to contract. When the locking tongue 408 corresponds to the locking groove 409, the locking spring 406 drives the locking tongue 408 to reset through the slide rod 407 and the pull plate 401, thereby locking the locking tongue 408 and the locking groove 409, thus achieving the installation and fixation of the placement frame 402.
