Problems solved by technology

At present, the adjustment of the radian of the coal gun is all based on manual experience. When manually adjusting the radian of the coal gun, the coal gun is manually injected into the coal outlet end, aligned with the steel structure, the steel plate gap, etc., and the coal gun is sprayed with force. The end presses out a certain arc, and the size of the adjusted arc is random and empirical. Everyone's experience is different, the adjusted arc is different, and the effect achieved is different.
A large number of inexperienced operators adjust the arc of the coal gun unreasonably, which causes the pulverized coal sprayed out during use to frequently wear the small sleeve, and it is impossible to ensure that the pulverized coal sprayed is in the center of the tuyere, which reduces the combustion effect of the pulverized coal
[0004] In view of the above problems, it is necessary to develop a coal gun arc adjustment mechanism and a coal gun arc adjustment method to solve the large randomness of the coal gun arc when the coal gun is manually bent, so that it is impossible to adjust the coal gun in the tuyere blowpipe and the tuyere small sleeve. problem of proper location

[0048] This embodiment provides a coal arc regulating mechanism. Such as figure 1 As shown, the coal radio regulating mechanism 1 includes an arcuate sleeve 11 and a tension assembly 12, and the coal gun 4 can be inserted into the curved sleeve 11, and bending and curved in the process of exiting the curved sleeve 11. The casing 11 is the same. The tensioning assembly 12 is hinged from both ends of the curved sleeve 11, and the tension assembly 12 can adjust the distance between the arc sleeve 11 to adjust the center angle of the arcuate sleeve 11.

[0049]The operator can adjust the distance between the arcuate sleeve 11 by tensioning the assembly 12 to curve the curved sleeve 11 as needed by the curved sleeve 4. The coal gun 4 is then penetrated into the curved sleeve 11, and the coal gun 4 is curved into the same radians as the arc slepens 11 in the action of the curved sleeve 11, and then the coal gun 4 can be removed. Since the arc of the curved sleeve 11 is fixed after setti...

[0058] This embodiment provides a coal arc regulating method, which adjusts the curvature of the coal gun 4 using the coal arc modulation mechanism 1 in the first embodiment.

[0059] Such as Figure 1 - Figure 3 As shown, the coal reform adjustment method can adjust the curved coal insertion hole 21 inserted from the coal gun insertion tube 2 and the curved portion 41 of the coal gun 4 in the air head blowing tube 2 and the air head small sleeve 3 inserted by the coal gun. Arc adjustment methods include:

[0060] Measuring the angle α between the coal insertion hole 21 and the central axis of the air head small sleeve 3 measures.

[0061] The tensioning assembly 12 is adjusted to adjust the center angle angle of the curved sleeve 11 to β, where β = 180 ° -α.

[0062] The coal gun 4 extends from one end of the curved sleeve 11.

[0063] The coal gun 4 is taken out when the coal gun 4 is reached at the other end of the arc sleeve 11.

[0064] Since the direction of the coal insertio...

Abstract

The invention discloses a coal gun radian adjusting mechanism and a coal gun radian adjusting method, and relates to the technical field of blast-furnace tuyere equipment. The coal gun radian adjusting mechanism comprises an arc-shaped sleeve and a tensioning assembly. A coal gun can be inserted into the arc-shaped sleeve and bent to be at the same radian as the arc-shaped sleeve in the process of extending into the arc-shaped sleeve. The tensioning assembly is hinged to the two ends of the arc-shaped sleeve and can adjust the distance between the two ends of the arc-shaped sleeve so as to adjust the central angle of the arc-shaped sleeve. The coal gun radian adjusting mechanism can standardize the radian of the arc-shaped part of the coal gun, the radian of the arc-shaped part is not affected by artificial experience, and thus the orientation of the coal gun is more accurate after an operator inserts the coal gun.

Description

Technical field [0001] The present invention relates to the technical field of blast furnace air outlets, and more particularly to a coal arc regulating mechanism and a coal gun radiative adjustment method. Background technique [0002] The blast furnace air is blown with coal powder. It is the use of coal guns to blow the coal-free coal-free coal in the blast furnace air outlet, and the coal powder into the blast furnace cylinder, combustion in high temperature and high pressure blast environments, producing reducing gas CO and release A large amount of thermal energy, replacing some metallurgy, achieving a reduction in blast furnace energy consumption. The blast furnace coal gun is inserted into the exhaust of the coal hole hole in the air-blown pipe, and the coal gun needs to adjust the coal spraying end of the coal gun in the sealed blow tube and the air-tunnel small set, which can prevent the spray pulverization from flushing small. The inner wall, leading to small sets of w...
