Description

Technical Field

[0001] This utility model relates to the field of waste gas pipeline technology, and in particular to a pipeline connection device for waste gas treatment. Background Technology

[0002] Waste gas treatment refers to the treatment of exhaust gases generated in production and daily life. Harmful substances in the waste gas are treated through adsorption, chemical reactions, and other methods to bring the waste gas up to emission standards and reduce environmental damage. Waste gas is generally transported through pipelines and enters a reaction tower for treatment. Pressure pipelines used in waste gas treatment, such as those for coal gas or steam, require welding during connection.

[0003] Currently, during welding, the pipe ends need to be manually aligned before welding along the circumferential joint. This manual alignment and welding consumes a lot of manpower and time, resulting in low pipe connection efficiency. Furthermore, the welded area around the pipe is uneven after welding, requiring workers to use a grinder to grind the pipe's circumference. This grinding process increases the workers' labor intensity, produces poor results, and has low efficiency. In response to this, this utility model provides a pipe connection device for waste gas treatment. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The exhaust gas treatment pipe connection device shown includes a fixed base 10, a first base plate 11 at one end of the top of the fixed base 10, a second base plate 12 at the other end of the top of the fixed base 10, and a support seat 20 fixedly installed on the top of the fixed base 10.

[0025] The rotating assembly includes a rotating gear disk 30 that is movable on the support base 20. A rotating motor 22 is fixedly installed on the top of the fixed base 10. The output end of the rotating motor 22 is connected to a drive gear 23 through the support base 20 via a rotating shaft. The drive gear 23 is movably meshed with the rotating gear disk 30.

A welding gun head 32 for welding pipes is provided on the first support plate 31. A grinding disc 34 is connected to the side of the rotating gear disk 30 away from the support base 20 via a second support plate 33.

[0026] The welding gun head 32 on the rotating gear 30 completes the circumferential welding at the connection of the two exhaust gas pipes. The grinding disc 34 on the rotating gear 30 grinds the weld seam in a circumferential manner, making the weld seam smooth. In the whole welding and grinding process, the labor intensity of workers is reduced and the efficiency of connecting exhaust gas pipes is improved.

[0027] See Figure 2 , Figure 3 , Figure 4 and Figure 5The fixed base 10 has a limiting groove 13 on its top. The fixed base 10 is slidably connected to the limiting slider 14 in the limiting groove 13. The top of the limiting slider 14 is fixedly installed at the bottom of the first base plate 11. The two ends of the first base plate 11 are threaded with positioning bolts 15, and the bottom of the positioning bolts 15 is opposite to the top of the fixed base 10. A servo motor 40 is fixedly installed inside the fixed base 10. The output end of the servo motor 40 is connected to a screw 41. A movable block 42 is threaded through the screw 41. The top of the movable block 42 is connected to the bottom of the second base plate 12 through a movable rod 45. A limiting base 16 for placing the pipe is fixedly installed on the top of the first base plate 11 and the second base plate 12. A fixing hole 17 is opened on the top of the limiting base 16. An electric telescopic rod 18 is fixedly installed at the bottom of the fixing hole 17. A positioning seat 19 for pressing and supporting the pipe is fixedly installed at the top of the electric telescopic rod 18.

[0028] The position of the exhaust pipe is horizontally adjusted by the limiting slide groove 13 under the first base plate 11 in conjunction with the limiting slider 14. The positioning bolts 15 at both ends of the first base plate 11 rotate and descend to abut against the fixed base 10, so that the exhaust pipe on the first base plate 11 moves to the appropriate position. The movable block 42 on the screw 41 is driven by the servo motor 40 to reciprocate under the action of the limiting rod 43, and then the movable block 42 drives the exhaust pipe on the second base plate 12 to move horizontally.

[0029] See Figure 2 , Figure 3 , Figure 4 and Figure 5 A limiting rod 43 is fixedly installed inside the fixed base 10. Both ends of the movable block 42 are movably inserted through the limiting rod 43. The fixed base 10 has a limiting groove 44, and the movable rod 45 is movably inserted through the limiting groove 44. A first hydraulic telescopic rod 35 is fixedly installed on the first support plate 31. The first hydraulic telescopic rod 35 is connected to a welding gun head 32. A second hydraulic telescopic rod 36 is fixedly installed on the second support plate 33. The second hydraulic telescopic rod 36 is connected to a grinding motor 37. The output end of the grinding motor 37 is connected to a grinding disc 34.

[0030] The second base plate 12 moves horizontally by means of the movable rod 45 on the movable block 42 in conjunction with the limiting groove 44. The position of the welding gun head 32 and the weld is adjusted by means of the first hydraulic telescopic rod 35. Similarly, the position of the grinding disc 34 and the weld is adjusted by means of the second hydraulic telescopic rod 36. The operation is simple and convenient.

[0031] The support base 20 has an annular groove 21 on the side near the rotating gear disk 30. An annular slider 24 is slidably connected to the support base 20 in the annular groove 21. The annular slider 24 is fixed on the rotating gear disk 30.

[0032] The annular groove 21, in conjunction with the annular slider 24, enables the rotating gear 30 on the support base 20 to rotate smoothly and stably, thereby completing the circumferential welding and circumferential grinding of the pipe weld joint.

[0033] The working principle of this utility model is as follows: Two exhaust gas pipes to be welded are placed on the top of the first base plate 11 and the second base plate 12 respectively. Specifically, the exhaust gas pipes are placed on the limiting base 16, and then the positioning seat 19 is lowered by the electric telescopic rod 18 to press and fix the exhaust gas pipes. The first base plate 11 is adjusted in position by the limiting slide groove 13 and the limiting slider 14 in conjunction with the positioning bolt 15. The movable block 42 on the screw 41 is driven by the servo motor 40 to move back and forth under the action of the limiting rod 43. The movable block 42 drives the second base plate 12 to adjust in position through the movable rod 45 and the limiting groove 44, so that the top ends of the two exhaust gas pipes are stably connected, which facilitates subsequent welding.

[0034] The connection of the exhaust gas pipe is adjusted to the position of the welding gun head 32. The drive gear 23 is driven by the rotary motor 22 to rotate. The drive gear 23 meshes and drives the rotating toothed disk 30 on the annular slider 24 to rotate stably and synchronously. During the rotation of the rotating toothed disk 30, the first hydraulic telescopic rod 35 on the first support plate 31 drives the welding gun head 32 to approach the connection of the exhaust gas pipe, realizing the circumferential welding of the pipe weld, which greatly improves the welding effect and reduces the labor intensity of the workers.

[0035] After welding is completed, the limiting support of the first base plate 11 is released by the positioning bolt 15, and the exhaust gas pipeline is driven to move horizontally by the movable block 42.

[0036] After the rotary welding is completed, the welding gun head 32 is reset by the first hydraulic telescopic rod 35, and then the grinding motor 37 and the grinding disc 34 are driven by the second hydraulic telescopic rod 36 on the second support plate 33 to perform circumferential grinding on the welded part of the exhaust gas pipe, so that the welded part is smooth and the labor intensity of the workers is reduced.
