Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas pipeline connection technology, and in particular to a connection device for waste gas purification equipment. Background Technology
[0002] Currently, factories that produce harmful gases or have high dust content in their exhaust gases typically install specialized exhaust gas purification equipment. This equipment draws these harmful gases or gases with high dust content into the purification system for further purification before discharging, thereby reducing harm to the atmospheric environment. Common exhaust gas purification equipment usually uses high-powered exhaust fans for ventilation. These fans are connected to the factory interior via pipes, and purification equipment such as activated carbon absorption boxes, UV purifiers, and scrubbing towers are installed in the middle of the pipes. When the exhaust fan draws in harmful gases, these gases first pass through the aforementioned purification equipment and are then discharged through the exhaust port of the exhaust fan, thus achieving the effect of exhaust gas purification.
[0003] However, during actual installation, it was found that the activated carbon absorption box, located between the exhaust fan and the pipes connecting to the factory's internal pipelines, was difficult to align horizontally with the pipes on both sides of the activated carbon absorption box because the exhaust fan and connecting pipes were mostly installed before the activated carbon absorption box was installed. This made it difficult to connect the inlet and outlet ports of the activated carbon absorption box horizontally with the pipes on both sides. It was necessary to raise the box on-site according to the height of the pipe interfaces until it was level with the pipe interfaces before the connection could be made, which caused inconvenience to the actual connection work.
[0004] Therefore, it is necessary to provide a new connection device for exhaust gas purification equipment to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please refer to the following: Figures 1-7The connecting device of the exhaust gas purification equipment includes: a support base 1, and a hollow lifting seat 2 above the support base 1, in which a bidirectional threaded rod 3 is rotatably installed. A servo motor is fixedly installed on one outer wall of the hollow lifting seat 2, and its output shaft is fixedly connected to one end of the bidirectional threaded rod 3. Two linkage plates 4 are threadedly installed on the bidirectional threaded rod 3. At the same time, two first limit rods are fixedly installed inside the hollow lifting seat 2. The two first limit rods pass through the two linkage plates 4 and are slidably connected to the two linkage plates 4 to ensure that the linkage plates 4 form a stable linear motion. The tops of the two linkage plates 4 are fixed. Two sliding plates 5 are installed, with their tops extending above the hollow lifting seat 2 and slidably connected to the top of the hollow lifting seat 2. A straightening plate 6 is fixedly installed on the top of each sliding plate 5, which can fix the activated carbon absorption box and adjust it to a vertically horizontally centered state. A first adjusting screw 11 is rotatably installed on the support base 1, with a threaded sleeve 12 threaded onto it. The top of the threaded sleeve 12 is fixedly connected to the hollow lifting seat 2. Four guide posts are fixedly installed on the top of the support base 1, and positioning blocks are slidably installed on each of the four guide posts. The positioning blocks are all fixedly connected to the hollow lifting seat 2, ensuring that the hollow lifting seat 2 can only move in a straight line. Frames 15 are provided on both sides of the hollow lifting seat 2, and connecting pipes 16 are provided inside each frame 15. Sealing rings are fixedly installed on the sides of the two connecting pipes 16 that are close to each other to ensure a tight seal when connected to the activated carbon absorption box. Second adjusting screws 17 are threaded onto the top of each frame 15, and the bottom ends of the two second adjusting screws 17 are rotatably connected to the two connecting pipes 16 respectively. Second limiting rods are slidably installed on the top of each frame 15. The bottom end of the tube is fixedly connected to two connecting tubes 16. The second limiting rod has the same function as the first limiting rod, which can restrict the movement trajectory of the connecting tube 16, so that it can only perform linear lifting and lowering movements. Two sliding seats 14 are provided on the top of the support base 1, and two frames 15 are respectively located above the two sliding seats 14. Two second electric push rods 20 are fixedly installed on the top of the support base 1. The output shafts of the two second electric push rods 20 are fixedly connected to the two sliding seats 14 respectively. The separation and contact between the connecting tube 16 and the activated carbon absorption box port are realized by the extension and retraction of the output shafts of the second electric push rods 20.
[0025] In the above method, in order to press down on the activated carbon absorption box and prevent it from shaking up and down, two fixed bending rods 7 are fixedly installed on one side of the outer wall of the hollow lifting seat 2. The top of the two fixed bending rods 7 is fixedly installed with the same crossbeam 8. The top of the crossbeam 8 is fixedly installed with a first electric push rod 9, whose output shaft passes through the crossbeam 8 and is slidably connected to the crossbeam 8. A limiting pressure plate 10 is fixedly installed on the output shaft of the first electric push rod 9. The limiting pressure plate 10 presses down on the activated carbon absorption box from top to bottom to fix it.
[0026] In this method, in order to facilitate the rotation of the first adjusting screw 11, two stabilizing blocks are fixedly installed at the bottom of the support base 1. The same manual crank 13 is rotatably installed on the two stabilizing blocks. Both the bottom end of the first adjusting screw 11 and one end of the manual crank 13 are fixedly installed with bevel teeth, and the two bevel teeth mesh with each other.
[0027] In this method, if the diameter of the connecting pipe 16 does not match that of the external corrugated pipe during later use, it is convenient to replace the connecting pipe 16. Each of the two sliding seats 14 is provided with a slot 18, and a plug block 19 is slidably installed in each of the two slots 18. Both the slots 18 and the plug blocks 19 are T-shaped, which has good stability and strength. The tops of the two plug blocks 19 are fixedly connected to the two frames 15 respectively, and both plug blocks 19 are fixedly connected to the corresponding sliding seats 14 by bolts. When replacing, simply remove the bolts and replace the frame 15 with the connecting pipe 16 of the corresponding size.
[0028] In this method, in order to ensure the stable sliding of the sliding seat 14, two inverted U-shaped sliding rods are fixedly installed on the top of the support base 1. The two inverted U-shaped sliding rods pass through the two sliding seats 14 respectively and are slidably connected to the corresponding sliding seats 14.
[0029] The working principle of the connection device for the waste gas purification equipment provided by this utility model is as follows:
[0030] In the initial state, the output shafts of the two second electric push rods 20 are extended;
[0031] When it is necessary to connect the activated carbon absorption box to the corrugated pipes on both sides, first place the activated carbon absorption box on the hollow lifting seat 2, then start the servo motor in the forward direction. Its output shaft drives the bidirectional threaded rod 3 to rotate. Under the limiting action of the first limit rod, the two linkage plates 4 begin to move towards each other. Finally, the two straightening plates 6 push the activated carbon absorption box to the longitudinal horizontal center position. Then, start the output shaft of the first electric push rod 9 to extend. Its output shaft drives the limiting pressure plate 10 to descend. Finally, the limiting pressure plate 10 presses on the top of the activated carbon absorption box to clamp it.
[0032] Then, adjust the height of the two connecting pipes 16 according to the height of the corrugated pipes on both sides. When adjusting, directly rotate the two second adjusting screws 17, and the connecting pipes 16 will move accordingly. Stop rotating the second adjusting screws 17 when both connecting pipes 16 have moved to the specified height. At this time, both connecting pipes 16 are horizontally aligned with the external corrugated pipes. Then connect the corrugated pipes to one end of the connecting pipes 16. At this time, the inlet and outlet ports on both sides of the activated carbon absorption box are not horizontally aligned with the two connecting pipes 16. Then, rotate the manual crank 13. Through the meshing between the two bevel teeth and under the guidance of the four guide columns, the hollow lifting seat 2 will lift the activated carbon absorption box until the ports on both sides of the activated carbon absorption box are horizontally aligned with the two connecting pipes 16. Stop rotating the manual crank 13. Then, start the output shafts of the two second electric push rods 20 to retract. The two connecting pipes 16 move closer to each other, and finally make the sealing rings on the two connecting pipes 16 fit with the ports on both sides of the activated carbon absorption box to form a passage, thereby completing the connection between the activated carbon absorption box and the external corrugated pipes.
[0033] Compared with related technologies, the connection device for the waste gas purification equipment provided by this utility model has the following beneficial effects:
[0034] This utility model provides a connection device for a waste gas purification equipment. By using two adjusting plates 6 that can move in opposite directions, the activated carbon absorption box can be pushed to a longitudinally horizontally centered position. Then, by using the cooperation of the first adjusting screw 11 and the threaded sleeve 12, the height position of the activated carbon absorption box can be adjusted according to the height position of the connecting pipe 16, so that the ports on both sides of the activated carbon absorption box are horizontally aligned with the connecting pipe 16. Furthermore, by rotating the second adjusting screw 17, the position of the connecting pipe 16 can be adjusted according to the height of the external corrugated pipe. Thus, it can be adaptively adjusted according to actual connection requirements, with a high degree of flexibility. The entire connection process has fewer steps and improves connection efficiency.
