[0002] Activated carbon adsorption boxes are suitable for treating organic waste gases at normal temperature, with large air volume, medium and low concentration, and easy to volatilize. The types of organic solvents that can be treated include benzene, ketone, ester, aldehyde, ether, alkane and their mixtures. It is applied to the purification of organic waste gases in petrochemical, chemical, pharmaceutical, painting, printing, rubber, fiber, and artificial leather workshops or production lines. The activated carbon filter plate is a key component of the activated carbon adsorption box. Currently, most activated carbon plates are fixedly installed with fixed groove plates arranged up and down inside the adsorption box, and then the activated carbon filter plate is inserted between the two groove plates. And to facilitate the installation of the activated carbon filter plate, the distance between the two groove plates is usually slightly larger than the size of the activated carbon filter plate. This causes the activated carbon filter plate to shake under the influence of gas flow during the adsorption process and generate abnormal noises. In addition, the current fixing structure also has the defect of being inconvenient for quickly replacing the activated carbon filter plate during cleaning. Summary of the Invention

Detailed Description of the Embodiment

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As Figures 1 to 8 shown, an activated carbon adsorption box that facilitates the cleaning, replacement and stable installation of activated carbon plates includes an adsorption box body 1, a preliminary filter cotton 2, a support grid plate 3, an activated carbon plate 4, an installation mechanism, a rear pressing assembly, a front pressing assembly and a closing cover plate 28.

[0020] Specifically, an air inlet 26 and an air outlet 27 are correspondingly arranged on the left and right sides of the adsorption box body 1, and the preliminary filter cotton 2 is arranged inside the adsorption box body 1 and near the air inlet 26. Six installation openings 6 are arranged on the front side wall of the adsorption box body 1. The six installation openings 6 are divided into upper and lower layers, and three are equally spaced in each layer. The support grid plate 3 is welded and fixed inside the adsorption box body 1. The support grid plate 3 is divided into upper and lower layers. The left end of the support grid plate 3 in the upper layer is connected to the inner top of the adsorption box body 1, the left end of the support grid plate 3 in the lower layer is connected to the inner bottom of the adsorption box body 1, and closing baffles 5 are correspondingly arranged between the right ends of the upper and lower support grid plates 3. Three groups of installation mechanisms are horizontally and equally spaced on each support grid plate 3. That is, in this embodiment, six activated carbon plates 4 can be installed in the adsorption box body 1 and are respectively corresponding to the six installation openings 6, so that the installation mechanism and the activated carbon plate 4 can extend out from the installation openings 6. Six closing cover plates 28 are provided, and their sizes are adapted to the installation openings 6 and are used to block the installation openings 6 to ensure the sealing performance of the adsorption box body 1. The closing cover plates 28 are fixedly installed on the front side wall of the adsorption box body 1 by screws. Two groups of rear pressing assemblies are distributed on the rear side of each group of installation mechanisms, and two groups of front pressing assemblies are distributed on the front side, so that four pressing assemblies correspond to the four sides of one activated carbon plate 4.

[0021] As a further improvement of this embodiment, each of the six groups of installation mechanisms includes two guiding slide bar plates 7 arranged side by side and equidistantly on the support grid plate 3, and a fixed grid plate 8 slidably installed on the two guiding slide bar plates 7. A stretching buckle groove 81 is provided on the lower side of the front end of the fixed grid plate 8, and a fixed groove 82 is provided on the fixed grid plate 8. A support grid plate 9 is arranged inside the fixed groove 82, and the activated carbon plate 4 is installed in the fixed groove 82 and its bottom is attached to the support grid plate 9. The stretching buckle groove 81 is used to facilitate the operator to pull out the fixed grid plate 8 and the activated carbon plate 4 thereon from the inside of the adsorption box body 1 for quick replacement; the size of the fixed groove 82 is adapted to the activated carbon plate 4, the depth of the fixed groove 82 is three-quarters of the height of the fixed grid plate 8, and the stretching buckle groove 81 is arranged on the remaining one-quarter of the front side wall. The front side of the fixed groove 82 is open, so as to facilitate the withdrawal of the activated carbon plate 4 from the fixed groove 82 for quick replacement and installation.

[0022] Further, hinge seats 91 are provided on both sides of the bottom of the rear end of the support grid plate 9, and hinge columns 83 are provided on the corresponding groove walls of the fixed groove 82. The hinge seats 91 are rotatably connected to the hinge columns 83 in a matching manner. Through the hinge seats 91 and the hinge columns 83, the support grid plate 9 can rotate around the bottom of its rear part. Cooperating with the open fixed groove 82, when the activated carbon plate 4 needs to be replaced, only by adjusting the angle of the support grid plate 9 to make it tilt downward, the activated carbon plate 4 can automatically slide out under the action of gravity, achieving the purpose of quick replacement.

[0023] Further, two support rods 10 are hinged on both sides of the bottom of the front end of the support grid plate 9, and two adjusting screw rods 11 are provided on both sides of the bottom of the fixed groove 82. Both of the two adjusting screw rods 11 are arranged in the front-rear direction, and the bottoms of the two support rods 10 are correspondingly hinged to the two adjusting screw rods 11. The front ends of the two adjusting screw rods 11 are correspondingly coaxially connected with two adjusting knobs 12. By driving the adjusting screw rods 11 to rotate through the adjusting knobs 12, the support rods 10 are tilted to make the support grid plate 9 tilt downward.

[0024] Furthermore, a limiting stop block 13 is coaxially and fixedly connected to the front side of the adjusting screw rod 11. The limiting stop block 13 is located on the front side of the support rod 10 and abuts against the limiting stop block 13 when the support rod 10 is in the vertical state. In this state, the support grid plate 9 is in a horizontal state. The limiting stop block 13 ensures that the support grid plate 9 will not be reset excessively when resetting from the inclined state to the horizontal state.

[0025] In addition, the support rod 10 and the adjusting screw rod 11 in this embodiment can also finely adjust the angle of the support mesh plate 9, ensuring that the activated carbon plate 4 can be evenly impacted by the air flow during the entire adsorption process. This avoids excessive pressure or wear on certain areas caused by long-term immobility, thereby extending the service life of the activated carbon plate 4; and optimizing the adsorption effect: different parts of the activated carbon plate 4 may have differences in adsorption capacity due to the accumulation of adsorbed substances. Slightly adjusting the position of the activated carbon plate 4 helps to redistribute these adsorbed substances, making the adsorption performance of the entire activated carbon plate 4 more balanced, and thus improving the overall waste gas treatment efficiency.

[0026] As a further improvement of this embodiment, each set of rear pressing components includes a sleeve 14 arranged on the support grid plate 3 and located on the side of the fixed mesh plate 8, a lower rotating rod 15 and an upper rotating rod 16 that are vertically staggered and rotatably installed in the sleeve 14, a torsion spring 161 installed inside the sleeve 14 and sleeved on the upper rotating rod 16, and transmission gears 17 correspondingly arranged on the lower rotating rod 15 and the upper rotating rod 16 and meshing with each other. A lower rotating block 18 extending outside the sleeve 14 is connected to the lower rotating rod 15, and the top of the upper rotating rod 16 extends outside the sleeve 14 and is connected to a rear pressing block 19. The rear pressing block 19 is located above the activated carbon plate 4, and the lower rotating block 18 and the rear pressing block 19 are distributed at a 90° angle in the vertical direction.

[0027] The sleeve 14 is provided with a notch adapted to the lower rotating block 18 to facilitate the extension and rotation of the lower rotating block 18 from the sleeve 14. The torsion spring 161 is used to reset the lower rotating block 18 and the rear pressing block 19.

[0028] As a further improvement of this embodiment, a rubber pressing pad 25 is provided on the lower pressing end face of the rear pressing block 19 in the rear pressing component. The highest point of the end face of the rubber pressing pad 25 is flush with the upper end face of the activated carbon plate 4. As the rear pressing block 19 rotates, the rubber pressing pad 25 presses on the activated carbon plate 4. The rubber pressing pad 25 can further ensure the pressing effect, and at the same time, using rubber material can also absorb the vibration generated during the operation of the activated carbon plate 4.

[0029] As a further improvement of this embodiment, the front pressing assembly includes a vertical rotating rod 20 disposed on the inner front sidewall of the adsorption box body 1 and above the installation opening 6, a rotating shaft 21 disposed on the front sidewall of the adsorption box body 1 and above the installation opening 6, and transmission bevel gears 22 correspondingly disposed on the upper end of the vertical rotating rod 20 and the inner shaft end of the rotating shaft 21 and meshing with each other. The lower end of the vertical rotating rod 20 is connected with a front pressing block 23. The front pressing block 23 is located above the activated carbon plate 4. A rotating knob 24 is connected to the outer shaft end of the rotating shaft 21. The rotating knob 24 is located outside the front side of the adsorption box body 1 and above the installation opening 6.

[0030] As a further improvement of this embodiment, a rubber pressing pad 25 is provided on the lower pressing end face of the front pressing block 23 in the front pressing assembly. The highest point of the end face of the rubber pressing pad 25 is flush with the upper end face of the activated carbon plate 4. As the rear pressing block 19 rotates, the rubber pressing pad 25 presses on the activated carbon plate 4. The rubber pressing pad 25 can further ensure the pressing effect, and at the same time, the use of rubber material can also absorb the vibration generated during the working process of the activated carbon plate 4.

[0031] The working principle and usage process of the present invention:

[0032] When it is necessary to clean and replace the activated carbon plate 4, first suspend the adsorption work, remove the closed cover plate 28, then rotate the left rotating knob 24 counterclockwise to rotate the corresponding front pressing block 23 to the left to cancel the pressing on the activated carbon plate 4, and rotate the right rotating knob 24 clockwise to rotate the corresponding front pressing block 23 to the right to cancel the pressing on the activated carbon plate 4; then pull out the fixed mesh plate 8 and the activated carbon plate 4 thereon together out of the adsorption box body 1 through the stretching buckle groove 81. During the process of pulling the fixed mesh plate 8 outwards, the lower rotating block 18 gradually loses the abutment of the fixed mesh plate 8 and, under the action of the torsion spring 161, resets to the horizontal state in the transverse direction, and the rear pressing block 19 resets to the horizontal state in the longitudinal direction.

[0033] After the activated carbon plate 4 completely extends out of the adsorption box body 1, rotate the adjustment knob 12 to drive the adjustment screw rod 11 to rotate, so that the front side of the support mesh plate 9 inclines downward. Under the action of gravity, the activated carbon plate 4 slides out of the fixed groove 82. Rotate the adjustment knob 12 again to make the support mesh plate 9 return to the horizontal state, and place a new activated carbon plate 4 on the support mesh plate 9. Stretch the buckle groove 81 again and push the fixed mesh plate 8 and the activated carbon plate 4 thereon into the adsorption box body 1. During the pushing process, the fixed mesh plate 8 abuts against the two lower rotating blocks 18 on the left and right sides and makes the two lower rotating blocks 18 rotate outward to the left and right. Through the transmission gear 17, the two rear pressing blocks 19 on the left and right sides rotate inward to the left and right to gradually press the upper end surface of the rear side of the activated carbon plate 4. After the fixed mesh plate 8 is completely pushed into the adsorption box body 1, the two rear pressing blocks 19 complete the pressing work; then, reversely rotate the two rotating knobs 24 on the outside to make the two front pressing blocks 23 press the upper end surface of the front side of the activated carbon plate 4. Thus, the rapid cleaning and replacement of the activated carbon plate 4 are completed. After all the pressing is completed, block the installation port 6 with the closed cover plate 28.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
