Description

Technical Field

[0001] The present application relates to the technical field of smoke pipe maintenance, and in particular to a smoke induction device for smoke pipe welding. Background Art

[0002] During the smelting process, due to factors such as thermal expansion and contraction, chemical corrosion, etc., the flue gas pipeline (also called the smoke pipe) often leaks, causing pollution to the production environment of the factory area and affecting the health and safety of the workers. When the smoke pipe leaks, the workers have to perform repair welding on the leaking point in the leaking smoke environment. Since the smoke will continue to overflow during the welding process, it is not only easy to cause damage to the health of the maintenance workers, but also because of the irritation of the smoke, it is difficult to concentrate when working in the smoke environment, which is easy to affect the quality of the smoke pipe repair. Utility Model Content

[0004] The present application provides a smoke entrainment device for smoke pipe welding, comprising a smoke entrainment tube, a fixing clamp, an exhaust assembly, and an iron wire. One end of the smoke entrainment tube is connected to a sealing nut via a fixing clamp, and the sealing nut is fixed to a smoke leakage location of the smoke pipe via an iron wire. The other end of the smoke entrainment tube is equipped with an exhaust assembly for exhausting smoke via a fixing clamp.

[0005] Optionally, in some embodiments, the smoke duct is formed by rolling iron sheets.

[0006] Optionally, in some embodiments, a plurality of groups of binding belts are provided on the outer wall of the smoke duct to improve the airtightness of the smoke duct.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0021] In the description of the present application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0022] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] At present, the specific process of repairing the smoke pipe 8 is as follows: after finding the leak point, select a suitable plugging nut 6 according to the size of the leak point, align the threaded hole of the plugging nut 6 with the leak point, and weld the plugging nut 6 to the smoke pipe 8. Full welding is used to prevent smoke from leaking from the welding gap. After the welding of the plugging nut 6 is completed, the corresponding plugging bolt 7 is installed through the thread, and then the connection between the plugging nut 6 and the plugging bolt 7 is sealed by full welding to complete the repair operation.

[0024] See also Figure 1 The smoke entraining device for smoke pipe welding includes a smoke entraining tube 1, a fixing fixture 2, an exhaust assembly 3, and an iron wire 5. The smoke entraining tube 1 is made of rolled iron sheets. After the iron sheets are rolled into a cylindrical shape, they are fixed with a binding belt 4. Since the iron sheets rebound after being rolled, the binding belt 4 can be adjusted to different diameters to limit the rebound of the iron sheets, thereby achieving adjustment of the diameter of the smoke entraining tube 1, which is convenient for entraining smoke from leakage points of smoke pipes 8 of different sizes.

[0025] A blocking nut 6 is placed at the port at one end of the smoke duct 1, and the smoke duct 1 and the blocking nut 6 are fixedly connected by a fixing clamp 2. When connecting, please note that sufficient margin of the blocking nut 6 is required to facilitate welding and avoid affecting the smoke duct 1 during welding. After the blocking nut 6 is fixed, align the blocking nut 6 with the leakage point on the smoke pipe 8, and use the iron wire 5 to tie the fixing clamp 2 to the smoke pipe 8, so as to fix the blocking nut 6 and facilitate subsequent welding operations.

[0026] See also Figure 2 At the other end of the smoke duct 1, an exhaust assembly 3 is fixed by a fixing fixture 2, comprising an outer frame 31, a bracket 32, a micro motor 33, and a fan blade 34. The outer frame 31 is fixedly installed at the end of the smoke duct 1 by the fixing fixture 2, and a micro motor 33 is fixedly installed in the outer frame 31 by the bracket 32. The fan blade 34 is fixedly connected to the output shaft of the micro motor 33. When smoke is drawn in, the micro motor 33 is started to drive the fan blade 34 to rotate, so that negative pressure is formed in the smoke duct 1, thereby draining the smoke.

[0027] See also Figure 3 The fixing fixture 2 includes an arc-shaped spring piece 21, an adjusting bolt 22, and an adjusting nut 23. The two arc-shaped spring pieces 21 are symmetrically arranged and connected by the adjusting bolt 22. The smoke duct 1 passes through the two arc-shaped spring pieces 21. The adjusting nut 3 is also threadedly connected to the adjusting bolt 22. The distance between the two arc-shaped spring pieces 21 can be adjusted by rotating the adjusting nut 23, thereby pressing the smoke duct 1 to fix it.

[0028] Specific working process:

[0029] After the device is assembled, the plugging nut 6 is aligned with the leaking point of the smoke pipe 8, and the device is fixed with the wire 5. The micro motor 33 is started to drive the fan blades 34 to rotate, thereby draining the smoke. The maintenance personnel weld and fix the plugging nut 6, and then install the plugging bolt 7 into the plugging nut 6. Finally, the joint between the plugging nut 6 and the plugging bolt 7 is welded and sealed to complete the repair welding operation.
