Description

Technical Field

[0001] The utility model relates to the technical field of ignition tools for large-scale boilers in power plants, and specifically relates to an ignition oil gun for power plant boilers. Background Art

[0002] When the burner of a power plant boiler is ignited, an ignition oil gun is required. During the existing ignition operation, to ensure that the head of the ignition gun is aligned with the ignition position inside the boiler burner and maintain an appropriate distance from the ignition rod to avoid ignition failure of the oil gun, first, the position of the oil gun rod needs to be adjusted. The oil gun and the ignition rod need to be withdrawn from the inside of the boiler burner. After withdrawal, the relative dimensional positions of the oil gun and the ignition rod are determined, and then the oil gun and the ignition rod are reinserted into the boiler burner. Therefore, when adjusting the position of the oil gun rod, it is necessary to withdraw the oil gun from the inside of the boiler burner for measurement and adjustment. The adjustment process is cumbersome and inefficient, and the oil gun cannot be put into use in time, affecting the power generation efficiency of the generator set. In severe cases, it may cause the unit to reduce load. In addition, due to the relatively long length of the existing ignition oil gun, it is difficult to accurately and quickly position it when inserting it into the boiler burner only by manual control, and it is also inconvenient for the operation and transportation of the entire ignition oil gun. In view of this, an ignition oil gun for power plant boilers is proposed. Summary of the Utility Model

[0003] The technical solution adopted by the utility model to solve the problems in the background art is as follows:

[0004] An ignition oil gun for a power plant boiler includes an ignition oil gun with an ignition head provided at its front end, and a scale is provided on the outer side wall of the ignition oil gun;

[0005] It further includes a guide sleeve and a mounting frame. The guide sleeve is installed on the top of the mounting frame. Openings are symmetrically provided on the outer wall of the guide sleeve, and rotatable guide wheels are installed in each opening. The ignition oil gun can be inserted into the guide sleeve, and the guide wheels can support on the outer wall of the ignition oil gun, enabling the ignition oil gun to move within the guide sleeve;

[0006] Four casters are provided at the bottom of the mounting frame for the mounting frame to move.

[0007] Preferably, two of the guide wheels are arranged in parallel in each opening.

[0008] Preferably, the axis of the guide wheel is inclined with respect to the axial direction of the guide sleeve, so that the contour surfaces of the guide wheels on both sides form a V-shaped angle.

[0009] Preferably, the casters are brake casters.

[0010] Preferably, the guide sleeve can swing horizontally on the top of the mounting frame.

[0011] The beneficial effects of the present utility model are as follows. First, the present utility model sets scales on the outer wall of the existing ignition oil gun. By using the scales, the ignition head of the ignition oil gun can accurately reach the specified ignition position inside the boiler, making the ignition operation more efficient and convenient, improving the success rate of the first ignition of the oil gun, and thus ensuring the safe and stable operation of the generator set. Second, the setting of the guide sleeve and the mounting bracket can support the ignition oil gun, avoiding the laborious disadvantage of the operator holding the ignition oil gun by hand, facilitating the adjustment of the insertion accuracy of the ignition oil gun, and also facilitating the carrying and handling of the ignition oil gun, improving the convenience of use.

[0016] The following further illustrates the above solutions with specific embodiments. It should be understood that these embodiments are used to illustrate the present utility model rather than limit the scope of the present utility model. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers. The implementation conditions not specified are usually those in conventional experiments.

[0017] In a specific embodiment, a power plant boiler ignition oil gun is provided. The same as the existing ones, it includes an ignition oil gun 1, and an ignition head 1.1 is provided at its front end. During use, the ignition head 1.1 is placed at a suitable ignition position inside the boiler.

[0018] In this application, to accurately control the position of the ignition head 1.1, it is usually determined according to the insertion depth of the ignition oil gun 1 into the boiler. Therefore, for more intuitive, rapid, and accurate positioning, a scale 1.2 is provided on the outer side wall of the ignition oil gun 1, and the minimum unit of the scale can be accurately measured to the millimeter unit.

[0019] This application aims to eliminate the need for manually holding the ignition oil gun 1. It further includes a guide sleeve 2 and a mounting bracket 3. The guide sleeve 2 is installed on the top of the mounting bracket 3. Symmetrically arranged openings 2.1 are provided on the outer wall of the guide sleeve 2, and rotatable guide wheels 2.2 are installed in each opening 2.1. After the ignition oil gun 1 is inserted into the guide sleeve 2, the guide wheels 2.2 can support on the outer wall of the ignition oil gun 1, enabling the ignition oil gun 1 to move freely and easily within the guide sleeve 2. Thus, the operation is more labor-saving, which is convenient for the operator to perform precise position adjustment. In addition, since the ignition oil gun 1 is relatively long, for easy carrying and movement, four casters 4 are provided at the bottom of the mounting bracket 3, enabling the mounting bracket 3 to move via the casters, thereby improving the usability.

[0020] Therefore, through the structural improvement of the existing ignition oil gun, the use of scales enables the ignition head of the ignition oil gun to accurately reach the specified ignition position inside the boiler. By visually judging the size of the oil gun inserted into the boiler burner, the success rate of the oil gun's first ignition is improved, thus ensuring the safe and stable operation of the generator set.

[0021] On this basis, to further ensure the stable cooperation between the guide wheels 2.2 and the outer wall of the ignition oil gun 1, two guide wheels 2.2 are provided in each opening 2.1, and the two guide wheels 2.2 are arranged side by side. Therefore, there are two contact points between the ignition oil gun 1 and the guide wheels 2.2 on each side, thus avoiding the up and down shaking of the end of the ignition oil gun 1 and making the forward and backward movement of the ignition oil gun 1 smoother.

[0022] Similarly, to further facilitate the left and right positioning of the ignition oil gun 1, the axis of the guide wheel 2.2 is inclined with respect to the axial direction of the guide sleeve 2, forming a V-shaped angle between the contour surfaces of the guide wheels 2.2 on both sides.

[0023] During use, to avoid the deficiency that the mounting bracket 3 needs to be supported by someone to prevent it from moving, the casters 4 are selected as brake casters. Therefore, by restricting the movement of the casters, while ensuring that the mounting bracket 3 does not move, it also eliminates the need for one person to support the mounting bracket, enabling one-person ignition operation.

[0024] In addition, during use, to facilitate the fine adjustment of the pointing direction of the ignition head of the ignition oil gun 1, the guide sleeve 2 can swing horizontally on the top of the mounting bracket 3. Mainly, the two rotate relative to each other horizontally and are positioned and locked using bolts.

[0025] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can make various changes and modifications completely within the scope without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
