Description

Technical Field

[0001] This utility model relates to the field of pipelines, specifically to a telescopic adsorption waste gas pipeline. Background Technology

[0002] To reduce environmental pollution, pipes with adsorption functions are often used to adsorb waste gas. For example, Chinese utility model patent (application number: 202222549085.1) discloses a telescopic waste gas adsorption pipe, which includes a waste gas pipe protective shell, an adsorption unit, and a telescopic unit. This pipe has the advantages of convenient waste gas adsorption and convenient replacement of the adsorption filter element, and the pipe sealing performance is improved.

[0003] However, the following defects were found in the actual application of this patented technology product: Since the pipeline is not equipped with a limiting component, the inspection door panel that is slidably connected to the protective shell of the exhaust gas pipeline is prone to sliding due to external force, which can easily affect the protective function of the inspection door panel for the adsorption unit. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a telescopic adsorption exhaust gas duct that can limit the cover plate such as the inspection door panel, making it less prone to displacement, stably protecting the adsorption box, and facilitating the disassembly and assembly of the cover plate.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the front of the docking box 1 is an open structure. A sealing ring is bonded to the flange 3 near the docking box 1. The side of the sealing ring has an opening corresponding to the first screw, which facilitates the passage of the first screw. A sealing gasket is bonded to the rear of the inspection cover 11. The end of the left screw 8 is connected to the first connecting block 4 through the first bearing, and the end of the right screw 8 is connected to the second connecting block 5 through the second bearing. A rotating sleeve is fixedly installed on the outside of the screw 8 to facilitate the rotation of the screw 8.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, the end of the left sliding rod 10 is fixedly connected to the first connecting block 4, and the end of the right sliding rod 10 is fixedly connected to the second connecting block 5. The side of the docking box 1 is provided with a connecting hole corresponding to the corrugated telescopic pipe 2, which facilitates ventilation. The horizontal plate 13 is fixedly installed on the left and right sides of the inspection cover 11, and the fixing block 14 is fixedly installed on the rear side of the horizontal plate 13. The inner wall of the fixing block 14 is provided with a sliding groove, and the sliding strip 15 is slidably installed in the sliding groove. The spring 16 is connected between the fixing block 14 and the docking plate 17. The protruding block 18 is fixedly connected to the docking plate 17, and the docking plate 17 is fixedly connected to the sliding strip 15. The side of the docking plate 17 is provided with a docking hole corresponding to the horizontal rod 22, which facilitates the passage of the horizontal rod 22.

[0031] like Figure 1-5 As shown, supports 20 are fixedly installed on the left and right sides of the docking box 1, respectively. Second screws 21 are screwed onto the side of supports 20. The side of supports 20 has threaded holes that mate with the second screws 21, facilitating their screwing. A horizontal rod 22 is fixedly connected to supports 20, with its end passing through the docking hole. The end of the second screw 21 abuts against the side of the protruding block 18. A handle is fixedly connected to the front of the inspection cover 11. Ventilation plates 25 are installed on both sides of the frame 26 using countersunk screws. Ventilation holes are provided on the side of the ventilation plates 25 for ventilation. The front of the frame 26 contacts the sealing gasket, and the rear of the frame 26 contacts the inner wall of the docking box 1.

[0032] In use: First, turn the second screw 21 of the second docking piece 19 away from the protruding block 18. The spring 16 of the first docking piece 12 will gradually return from its stretched state, which can drive the docking plate 17 and the sliding bar 15 away from the horizontal bar 22. The end of the horizontal bar 22 will move out of the docking hole of the docking plate 17. Then, hold the handle to remove the inspection cover 11. Then, take out the adsorption box 24 inside the docking box 1. Then, unscrew the countersunk screw, remove the ventilation plate 25, put zeolite into the left frame 26, and then put activated carbon into the right frame 26. Then, put the ventilation plate 25 back and then snap the adsorption box 24 back in place. Then, turn the second screw 21 in the opposite direction to install the inspection cover 11. Then, turn the rotating sleeve to drive the screw 8 to rotate. The screw 8 can drive the first connecting block 4 or the second connecting block 24 to rotate. The connecting block 5 moves horizontally, allowing the corrugated expansion tube 2 to extend and retract, enabling the transmission of exhaust gas to different lengths. Then, using bolts and nuts, the product is installed via the flange 3. The exhaust gas enters the docking box 1 through the corrugated expansion tube 2. The zeolite and activated carbon in the adsorption box 24 adsorb the exhaust gas. The first docking member 12 and the second docking member 19 limit the position of the inspection cover 11, preventing it from shifting and ensuring stable protection of the adsorption box 24. This also facilitates the disassembly and assembly of the inspection cover 11, making it easier to replace the adsorbent in the internal adsorption box 24. Furthermore, the transparent label frame 27 allows for the insertion of labels to remind staff to replace the adsorbent in the adsorption box 24 promptly.
