Description

Technical Field

[0001] The utility model relates to a tool which is convenient for checking the cutting circle of a four-corner burner and belongs to the technical field of burner nozzle checking. Background Art

[0002] Boiler four-corner burner is a common burner configuration, especially widely used in industrial boilers. The main feature of the four-corner burner is that it is arranged at the four corners of the furnace, in this way, a tangential combustion situation can be formed.

[0003] The four-corner tangential combustion method is prone to airflow deviation during boiler operation, causing problems such as flame sticking to the wall, eccentric burning, and unstable combustion. Long-term eccentric burning not only has an adverse effect on the water-cooled wall and water circulation, but also causes high-temperature corrosion of the water-cooled wall and scouring and tube bursting. In addition, eccentric burning will increase the temperature difference of the flue gas in the horizontal flue, causing superheater overheating or tube bursting, which will bring serious hidden dangers to normal production operation. Therefore, it is necessary to adjust the four-corner burner inside the boiler to avoid the problem of eccentric burning and solve the tangential calibration, acceptance and adjustment of the four-corner burner of the boiler.

[0004] In the process of implementing the technical solution of this application, the inventor discovered that there are at least the following technical problems in the prior art:

[0005] like Figure 8 As shown, when adjusting the burner nozzle, it is necessary to align the tangent of the designed tangent circle at the center of the furnace. The burner is usually adjusted according to the size of the circle required. The center vertical line of the adjusted burner nozzle must be tangent to the designed tangent circle or within the allowable deviation range. The existing method is to pull the steel wire along the center vertical line of the burner nozzle. It is necessary to find a point A on the steel wire, and then pull two ropes from the two symmetrical ends of the burner nozzle for measurement. Only when the two ropes are the same length, the steel wire is the center vertical line of the burner nozzle. Otherwise, the steel wire needs to be adjusted left and right. Since the diagonal distance in the combustion chamber is very long, it takes many adjustments to ensure that the two ropes are completely equal. Only then can the steel wire be on the center vertical line of the burner nozzle, and then the relevant verification data can be measured. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a tool for convenient circle cutting inspection of a four-corner burner, which can be pre-aligned before the rope is pulled, thereby reducing the number of rope adjustment times.

[0007] The utility model provides a tool for convenient rounding calibration of a four-corner burner, comprising a clamping part for clamping and fixing the burner nozzle;

[0008] A vertical slide rail is fixed on the clamping part, and a horizontal slide rail which can move up, down, left and right is installed on the vertical slide rail;

[0009] The clamping part at least includes a fixed plate installed on the top of the vertical slide rail, a movable plate with sliding fit is installed correspondingly below the vertical slide rail, the movable plate is arranged correspondingly above and below the fixed plate, a locking piece is elastically connected below the movable plate, and the locking piece is slidably fitted with the vertical slide rail;

[0010] A laser emitting mechanism which can move left and right is installed on the side of the horizontal slide rail which is away from the vertical slide rail.

[0011] Furthermore, a locking rod with threaded fit is provided on the locking member, and when the locking rod is rotated, the end of the locking rod abuts against the surface of the vertical slide rail for fixation.

[0012] Furthermore, the laser emitting mechanism comprises a base matched with the transverse slide rail, a fixing cylinder is mounted on the base, and a laser emitter is fixed in the fixing cylinder.

[0013] Furthermore, the vertical slide rail and the horizontal slide rail are connected by a cross hinge seat.

[0014] Furthermore, the elastic connection between the movable plate and the locking member is achieved by a compression spring connection.

[0015] Furthermore, the vertical slide rail and the horizontal slide rail are designed in profile.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The clamping part of the utility model is fixed on the burner nozzle, and the relative position of the laser emitting mechanism and the burner nozzle can be conveniently adjusted by utilizing the moving characteristics of the vertical slide rail and the horizontal slide rail, so that the laser emitting mechanism is located in the middle position of the burner nozzle, thereby achieving pre-alignment before pulling the rope, reducing the number of rope adjustment times, and improving the efficiency of the circle cutting effect.

[0033] Example 1

[0034] like Figures 1 to 8 As shown, the tool for convenient rounding calibration of a four-corner burner of the utility model comprises a clamping portion 5 for clamping and fixing the burner nozzle 6;

[0035] A vertical slide rail 4 is fixed on the clamping portion 5, and a horizontal slide rail 2 is installed on the vertical slide rail 4 so as to be movable up, down, left, and right;

[0036] The clamping part 5 includes at least one fixed plate 51 installed on the top of the vertical slide rail 4, so that when installing, the fixed plate 51 can be placed on the burner nozzle 6 by hand, and a sliding movable plate 52 is installed correspondingly below the vertical slide rail 4. The movable plate 52 is arranged correspondingly to the fixed plate 51 above and below. A locking member 54 is elastically connected below the movable plate 52. The elastic connection design between the movable plate 52 and the locking member 54 can achieve buffering during the clamping process of the clamping part 5 and the burner nozzle 6 through elastic deformation after the clamping part clamps and fixes the burner nozzle 6, avoiding pure rigid clamping; the locking member 54 is slidably matched with the vertical slide rail 4;

[0037] A laser emitting mechanism 1 which can move leftward and rightward is installed on the side of the transverse slide rail 2 which is away from the vertical slide rail 4 .

[0038] The locking member 54 is provided with a locking rod 541 which is threadedly matched. When the locking rod 541 is rotated, the end of the locking rod 541 abuts against the surface of the vertical slide rail 4 to be fixed.

[0039] The laser emitting mechanism 1 includes a base 11 matched with the transverse slide rail 2, a fixed cylinder 12 is installed on the base 11, and a laser emitter 13 is fixed in the fixed cylinder 12. The base 11 slides on the transverse slide rail 2 to increase the distance of left and right movement. The laser emitter 13 can be a laser pen that emits light.

[0040] A cross hinge seat connection 3 is adopted between the vertical slide rail 4 and the transverse slide rail 2, and the transverse slide rail 2 can move up, down, left and right through the cross hinge seat connection 3.

[0041] The movable plate 52 and the locking member 54 are elastically connected by a compression spring 53 .

[0042] The vertical slide rail 4 and the horizontal slide rail 2 are designed with profiles, and a double-slide profile design is adopted.

[0043] Working process or working principle:

[0044] The clamping part 5 is clamped on the burner nozzle 6. The locking member 54 in the clamping part 5 pushes the movable plate 52 to move upward. The inner plane 41 of the vertical slide rail 4 needs to be parallel to the outer plane 61 of the burner nozzle 6. After clamping, the locking rod 541 is rotated to fix the movable plate 52.

[0045] Then move the laser emitting mechanism 1 to the middle position of the burner nozzle 6, thereby turning on the laser emitter 13, and a mark will appear at the diagonal position. At this time, pull up the steel wire, and then use the ropes at both ends for verification.

[0046] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up, and down, does not constitute a limitation of the present invention, but is only for the convenience of description.
