Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a vertical shaft smoke exhaust pipeline. Background Art

[0002] At present, a Chinese utility model with announcement number CN215802936U discloses a commercial smoke exhaust duct, including a plurality of pipe body splicing monomers and a splicing structure. The plurality of pipe body splicing monomers are spliced ​​in turn through the splicing structure to form a commercial smoke exhaust duct, and the pipe body splicing monomers include a metal lining and a cement outer layer covering the surface of the metal lining. The commercial smoke exhaust duct of the utility model is formed by splicing a plurality of pipe body splicing monomers through the splicing structure, which is convenient for processing and installation. The pipe body splicing monomer is composed of a metal lining and a cement outer layer. The metal lining can meet the needs of cooling and flowing out the oil fume attachments. The cement outer layer can increase the thickness of the pipe, enhance its rigidity, and reduce the thickness of the metal lining to save costs. At the same time, due to the coating of the cement outer layer, the metal lining can be better protected to avoid rusting and increase the service life of the pipe.

[0003] Although the existing smoke exhaust duct can be prefabricated in the factory in advance and then quickly spliced ​​on site, there are still other problems during use, such as the lack of side protection function. Due to the narrow internal space of the shaft, when the top riser frame is hoisted above the shaft, the lower riser frame will shake. When the lower riser frame shakes, its side is very likely to rub and collide with the inside of the shaft wall. If the collision causes damage, there will be air leakage, which is less safe and inconvenient to disassemble and assemble the filter plate. When there is too much dust attached to the top filter plate, personnel need to use tools to remove the screws used to fix the filter plate before removing the filter plate from the riser, which reduces the cleaning efficiency of personnel. In order to solve the above-mentioned problems, we propose a shaft smoke exhaust duct. Utility Model Content

[0004] The utility model aims to provide a vertical shaft smoke exhaust pipe, which solves the problem that the existing smoke exhaust pipe does not have a side protection function and is not convenient for quick disassembly and assembly of the filter plate.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a vertical shaft smoke exhaust pipe comprises a first pipe, a second pipe is arranged at the bottom of the first pipe, locking bolts are installed through the tops of both sides of the second pipe, threaded holes are opened at the bottoms of both sides of the first pipe and the second pipe, protective plates are symmetrically arranged on both sides of the first pipe and the second pipe, first fixing springs are bolted to the protective plates through spring fixing sheets on both sides of the first pipe and the second pipe, a filter screen is placed on the top of the first pipe, a mounting plate is symmetrically welded to the top of the filter screen, a movable plate is arranged inside the mounting plate, a limiting block is welded on one side of the movable plate, a second fixing spring is bolted between the other side of the movable plate and the mounting plate through a spring fixing sheet, and a fixing rod is welded on the other side of the movable plate.

[0006] The above technical solution can provide side protection function to avoid direct collision between the pipeline and the well wall, with high safety. At the same time, it can facilitate quick disassembly and assembly of the filter plate, and the operation is simple and convenient, which improves the cleaning efficiency of personnel and is highly practical.

[0007] The utility model is further configured as follows: a rubber pad is bonded to the outside of the protective plate.

[0008] By adopting the above technical solution and setting the rubber pad, the force generated when the protective plate collides with the well wall can be reduced.

[0009] The utility model is further configured as follows: a limiting rod is welded on the other side of the movable plate, and the other end of the limiting rod penetrates and extends to the outside of the mounting plate.

[0010] By adopting the above technical solution, the movable plate can be limited by setting the limiting rod to prevent the movable plate from tilting during the process of moving left and right.

[0011] The utility model is further configured as follows: a pull plate is welded on the other end of the fixing rod.

[0012] By adopting the above technical solution and providing the pull plate, it is convenient for personnel to pull the fixing rod outward by hand.

[0013] The utility model is further configured as follows: the first pipe and the second pipe are both internally installed with thermal insulation linings.

[0014] By adopting the above technical solution and providing a thermal insulation lining, the thermal insulation effect inside the first pipe and the second pipe can be improved.

[0015] The utility model is further configured as follows: the protective plate is made of stainless steel.

[0016] By adopting the above technical solution, the protective plate has the characteristics of high strength, low density and excellent corrosion resistance.

[0017] The utility model is further configured as follows: the first fixing spring and the second fixing spring are both made of carbon spring steel.

[0018] By adopting the above technical solution, the first fixed spring and the second fixed spring have the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model can make the protective plate collide with the inner wall of the shaft when the first pipe and the second pipe shake when the pipeline is hoisted for installation. The protective plate will move inward after the collision. When moving inward, the protective plate will press the first fixed spring to make it enter a contracted state. When the first fixed spring contracts and stores energy, it will absorb and offset the impact force, so as to have a side protection function, avoid direct collision between the pipeline and the shaft wall, and have high safety.

[0021] 2. The utility model pulls the pull plate outward by grasping it with hands. When the pull plate is pulled outward, it drives the movable plate to move outward through the fixation of the fixed rod. When the movable plate moves outward, it will not only squeeze the second fixed spring, but also drive the limit block to separate from the through hole on the side of the first pipe. When the pull plate is pulled to the bottom, it can be pulled upward, which can facilitate the quick disassembly and assembly of the filter plate, the operation is simple and convenient, which improves the cleaning efficiency of personnel and has high practicality.
