Description

Technical Field

[0001] The utility model relates to the technical field of soot cleaning devices, in particular to a soot cleaning mechanism and a soot cleaning device for a smoke pipe of a heating furnace. Background Art

[0002] In recent years, the average thermal efficiency of various heating furnaces used in oil fields is only about 80%, that is, 20% of the heat generated by fuel combustion is not used, of which the heat dissipation of the furnace body accounts for about 1.5%, the failure of fuel (natural gas) to fully burn accounts for 3%, and the remaining 15.4% of the heat is discharged into the atmosphere through flue gas. The reason is that a large amount of soot accumulates in the smoke pipe, blocking the smoke pipe and fire pipe (the thermal conductivity of soot is 400 times smaller than that of steel), which greatly reduces its thermal conductivity, causing heat loss of about 12.4%, and a large amount of heat is discharged into the atmosphere through flue gas without heat exchange. Therefore, reducing the ash collection thickness of the flue wall and increasing the heat transfer rate are the most effective ways to reduce flue gas temperature, improve furnace efficiency, and save fuel.

[0003] At present, on the one hand, it is difficult to clean the flue due to the constraints of the flue pipe structure. Under the current conditions, it is impossible to completely remove the ash, and only simple dredging can be carried out. On the other hand, ordinary four-point steel pipes are used to move back and forth directly in the flue to make the ash fall and be cleaned out. However, the cleaning effect is general, and it will take a while to clean it again, and the cleaning cycle is short. Utility Model Content

Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0026] Below, refer to Figure 1-2 A soot cleaning mechanism and a soot cleaning device for a smoke duct of a heating furnace according to an embodiment of the utility model are specifically described.

[0027] like Figure 1As shown, according to an embodiment of the utility model, a smoke ash cleaning mechanism for a heating furnace smoke pipe is provided, comprising a connecting seat 1, a diameter reducing module 2, a cleaning component 3 and a driving module 4, wherein the diameter reducing module 2 comprises a first diameter reducing component 21 and a second diameter reducing component 22, wherein the first diameter reducing component 21 is arranged at one end of the connecting seat 1, and the second diameter reducing component 22 is arranged at the other end of the connecting seat 1; the cleaning component 3 is arranged at the ends of the first diameter reducing component 21 and the second diameter reducing component 22 away from the connecting seat 1 to clean the inner wall of the heating furnace smoke pipe 01; the working end of the driving module 4 is connected to the connecting seat 1 The right side wall is connected to provide driving force; wherein, when the driving module 4 is energized to drive the connecting seat 1 to move right, one end of the first reducing component 21 and the second reducing component 22 are both in contact with the driving module 4, so that the other ends of the first reducing component 21 and the second reducing component 22 expand and abut against the heating furnace smoke pipe 01; when the driving module 4 is de-energized to push the connecting seat 1 to move left, one end of the first reducing component 21 and the second reducing component 22 are both detached from the driving module 4, so that the other ends of the first reducing component 21 and the second reducing component 22 shrink and release the heating furnace smoke pipe 01.

[0028] It should be noted that when the driving module 4 is powered on, it drives the connecting seat 1 to move rightward. When the connecting seat 1 is fixed, the driving module 4 is powered on so that the driving module 4 moves leftward to abut against the connecting member and then abuts against one end of the first reducing component 21 and the second reducing component 22.

[0029] Therefore, the ash cleaning mechanism and ash cleaning device for the smoke pipe of the heating furnace of the utility model solve the technical problems in the prior art that the flue can only be simply unblocked and the cleaning cycle is short, and achieves beneficial effects: the ash cleaning mechanism adopts an ingenious openable and closable structure, has a simple structure, and is easy to install and use; when the ash cleaning mechanism is applied to the ash cleaning device, it can clean carbon deposits and extend the cleaning cycle of the smoke pipe 01 of the heating furnace, thereby reducing the flue gas temperature, improving the furnace efficiency, and saving fuel.

When the driving module 4 loses power and pushes the connecting seat 1 to move left, one end of the first outer diameter transmission connecting rod is separated from the driving module 4 so that the other end of the first outer diameter transmission connecting rod contracts and releases the heating furnace smoke pipe 01.

[0039] It should be noted that the other end of the driving module 4 away from the connecting socket 1 can be connected in series with another connecting socket 1 to realize the series connection between the driving modules 4; when the driving modules 4 in the odd group are powered on, the driving modules 4 in the even group are powered off, and when the driving modules 4 in the odd group are powered off, the driving modules 4 in the even group are powered on.

[0043] When the spring 42-type mass electromagnets of the even array are energized and the spring 42-type mass electromagnets of the odd array are de-energized, the spring 42 of the even array is compressed and abuts against the connecting seat 1, the first outer diameter transmission connecting rod 211 and the second outer diameter transmission connecting rod 221 of the even array perform expansion movement, the first variable diameter transmission connecting rod 212 and the second variable diameter transmission connecting rod 222 of the even array simultaneously drive the steel wire sheet 31 to expand movement, and the steel wire sheet 31 of the even array abuts against the smoke pipe 01 of the heating furnace to clean up the accumulated dust, and at the same time, the spring 42 of the odd array is reset to push the connecting seat 1 to move left, the first outer diameter transmission connecting rod 211 and the second outer diameter transmission connecting rod 221 of the odd array perform contraction movement, the first variable diameter transmission connecting rod 212 and the second variable diameter transmission connecting rod 222 of the odd array simultaneously drive the steel wire sheet 31 to contract movement, and the steel wire sheet 31 of the odd array moves left; when the spring 42-type mass electromagnets of the odd array are energized and the spring 42 of the even array are de-energized When the spring 42-type mass electromagnet loses power, the spring 42 of the odd array abuts against the connecting seat 1, the first outer diameter transmission connecting rod 211 and the second outer diameter transmission connecting rod 221 of the odd array perform expansion movement, the first variable diameter transmission connecting rod 212 and the second variable diameter transmission connecting rod 222 of the odd array simultaneously drive the steel wire sheet 31 to expand movement, and the steel wire sheet 31 of the odd array abuts against the heating furnace smoke pipe 01 to clean the accumulated ash.
