Description

Technical Field

[0001] This invention relates to the field of ignition oil gun technology for power plants, and more specifically, to a novel ignition oil gun for power plants. Background Technology

[0002] A power plant ignition oil gun is a device used to actively spray flames to heat up a power plant boiler when it is shut down because the temperature inside the boiler is too low, causing pulverized coal to fail to ignite.

[0003] However, the existing ignition oil gun needs to be inserted into the boiler. The part inserted into the boiler cannot be observed from the outside. At the same time, because the part inserted into the boiler is subject to alternating hot and cold and uneven heating, the part of the ignition oil gun will deform and bend. Slight deformation will not affect the use, but when the bending and deformation gradually become more serious and cannot be detected in time, it will affect the direction of the ignition oil gun spray and make it impossible to withdraw from the boiler. Summary of the Invention

[0004] The purpose of this invention is to provide a new type of ignition oil gun for power plants, which solves the problem that the ignition oil gun in the boiler section cannot be observed, and gradually deforms and bends due to uneven heating and alternating hot and cold temperatures. When the bending is severe, it is not adjusted in time, which affects the direction of the ignition oil gun spray and makes it difficult to remove and take it out of the boiler.

[0005] This invention is achieved through the following technical solution: This invention provides a novel ignition oil gun for power plants, comprising a body, an internal positioning sleeve, an oil gun connected to one end of the middle of the positioning sleeve, and a high-pressure air inlet at the bottom of the body. The invention is characterized by a cavity inside the outer shell of the body, a fixing block connected to one end of the cavity near the body, an observation block connected to the end of the cavity away from the fixing block, a traction cable connected between the observation block and the fixing block, an observation opening near the observation block in the cavity, and limiting blocks hinged to both sides of the inner wall of the cavity.

[0006] Preferably, the observation block also includes a telescopic rod, which is located at the end of the observation block away from the traction cable.

[0007] Preferably, one end of the cavity is provided with a groove that mates with the telescopic rod. The telescopic rod consists of two rods of different diameters that fit together, and the two rods are connected by a spring.

[0008] Preferably, the limiting block further includes a hinge shaft and a transmission rod, with the hinge shaft disposed at the upper and lower ends of the limiting block and the transmission rod connected to one side of the hinge shaft.

[0009] Preferably, the side wall of the hinge shaft is provided with a gear, and one side of the transmission rod is provided with a rack that meshes with the gear on the side wall of the hinge shaft.

[0010] Preferably, the rack on one side of the transmission rod meshes with the gears of the hinge shafts on several limiting blocks, and the bottom of the transmission rod is connected to the groove by a spring.

[0011] Preferably, the limiting block is arranged in an "L" shape, and one end of the limiting block protrudes on both sides of the middle of the cavity.

[0012] Preferably, the observation opening also includes a scale, which is set on one side of the observation opening.

[0013] Preferably, the observation opening is an opening at one end of the cavity that connects to the observation block and communicates with the outside, and the width of the opening is smaller than that of the observation block.

[0014] Preferably, the cavity further includes deflection grooves, which are formed on both sides of the middle part of the cavity, and the deflection grooves are hinged to the limiting blocks.

[0015] The technical solution of the present invention has at least the following advantages and beneficial effects: 1. By cooperating with the fixed block in the cavity of the device, when the main body bends in the part of the furnace during start-up and shutdown, the distance between the fixed block and the observation block increases, which will cause the observation block to be displaced. This allows the displacement of the observation block to be directly observed through the observation opening, so as to grasp the bending situation of the main body in the part of the furnace during start-up and shutdown in a timely manner and make timely adjustments.

[0016] 2. The device is also equipped with limiting blocks. By observing several limiting blocks on both sides of the center of the opening, one side of the observation block can be pressed against and fitted, thereby limiting the position of the observation block and preventing it from moving easily on its own and affecting the judgment. At the same time, when the observation block is pulled, the limiting blocks can also deflect and reset in accordance with the movement and stopping position of the observation block, so as to accurately control the displacement distance of the observation block and prevent excessive errors.

Detailed Implementation

[0025] The following is combined with Figures 1 to 7 The present invention will be described in detail below.

[0026] A novel ignition oil gun for power plants includes a body 1. A positioning sleeve 101 is provided inside the body 1. An oil gun 102 is connected to one end of the middle part of the positioning sleeve 101. A high-pressure air inlet 103 is provided at the bottom of the body 1. A cavity 2 is provided inside the outer shell of the body 1. A fixing block 201 is connected to one end of the cavity 2 near the body 1. An observation block 202 is connected to one end of the cavity 2 away from the fixing block 201. A traction cable 2021 is connected between the observation block 202 and the fixing block 201. An observation opening 204 is provided in the part of the cavity 2 near the observation block 202. Limiting blocks 203 are hinged to both sides of the inner wall of the cavity 2.

[0027] First, the front end of the main body 1 is connected to the inside of the start-up furnace. Then, the atomized oil sprayed from the oil gun 102 inside the main body 1 is ignited by the ignition device, thereby igniting and heating the start-up furnace. When the oil gun 102 sprays the oil, high-pressure gas is injected through the high-pressure gas inlet 103. Then, the high-pressure gas impacts the sprayed oil, further breaking and atomizing the oil, making the oil sprayed from the main body 1 more thoroughly atomized for easier ignition.

[0028] Furthermore, the limiting block 203 also includes a hinge shaft 2031 and a transmission rod 2032. The hinge shaft 2031 is disposed at the upper and lower ends of the limiting block 203. The transmission rod 2032 is connected to one side of the hinge shaft 2031. A gear is provided on the side wall of the hinge shaft 2031. A rack is provided on one side of the transmission rod 2032, which meshes with the gear on the side wall of the hinge shaft 2031. The rack on one side of the transmission rod 2032 meshes with the gears of the hinge shaft 2031 on several limiting blocks 203. The bottom of the transmission rod 2032 is connected to a groove via a spring. 3 is arranged in an "L" shape, and one end of the limiting block 203 protrudes on both sides of the middle part of the cavity 2. The observation opening 204 also includes a scale 2041, which is set on one side of the opening of the observation opening 204. The observation opening 204 is an opening that connects one end of the cavity 2 to the observation block 202 and communicates with the outside. The width of the opening part of the observation opening 204 is smaller than that of the observation block 202. The cavity 2 also includes a deflection groove 205, which is opened on both sides of the middle part of the cavity 2. The limiting block 203 is hinged in the deflection groove 205.

[0029] Meanwhile, when the part of the main body 1 located inside the start-up / shutdown furnace bends due to uneven heating, the fixing block 201 near the oil gun 102 in the cavity 2 will shift due to the bending, causing the thread between the fixing block 201 and the observation block 202 to lengthen. Therefore, when the main body 1 bends, the fixing block 201 will exert a certain force on the traction cable 2021 to pull the observation block 202 along the cavity 2. The movement range of the observation block 202 is within the observation opening 204, which is located outside the start-up / shutdown furnace. Therefore, when the observation block 202 is dragged and moved, it can be directly seen through the observation opening 204 to promptly know whether the part of the main body 1 located inside the start-up / shutdown furnace has bent. This avoids the situation inside the start-up / shutdown furnace not being known in time when the bending is slight, which could lead to the bending becoming more severe and making it impossible to pull the main body 1 out of the start-up / shutdown furnace.

[0030] At the same time, when the observation block 202 is located in the observation opening 204, one side of the observation block 202 will abut against the limiting block 203 in the deflection grooves 205 on both sides of the middle of the observation opening 204. The "L" shape of the limiting block 203 itself makes the longer part of the limiting block 203 protrude on the deflection groove 205, so that one side of the observation block 202 will fit against the protruding part of the limiting block 203, so that the observation block 202 will not slide confidently in the observation opening 204 when it is not being pulled.

[0031] Meanwhile, the limiting block 203 is connected to the deflection groove 205 through the hinge shaft 2031. The torsion spring of the hinge shaft 2031 prevents the limiting block 203 from easily deflecting on its own, thereby allowing the limiting block 203 to form a restraining and limiting force against the observation block 202.

[0032] Several limiting blocks 203 set on both sides of the middle of the observation opening 204 can form a limiting abutment at the corresponding part of the pulled position when the observation block 202 is bent and pulled due to the displacement of the main body 1 to start and stop the furnace. This prevents the observation block 202 from sliding a certain distance on its own after being pulled, which would make it impossible to accurately know the degree of bending. The distance that the observation block 202 is pulled can be known through the scale 2041, so as to accurately know the degree of bending of the main body 1, so that it can be removed and adjusted in time when the degree of bending affects the removal and disassembly.

[0033] Furthermore, the observation block 202 also includes a telescopic rod 202, which is located at the end of the observation block 202 away from the traction cable 2021. One end of the cavity 2 is provided with a groove that mates with the telescopic rod 202. The telescopic rod 202 consists of two rods of different diameters that fit together, and the two rods of the telescopic rod 202 are connected by a spring.

[0034] Finally, one end of the observation block 202 is connected to the middle end of the observation opening 204 via a telescopic rod 2022. When the main body 1 is found to be bent and promptly removed for adjustment, one of the limiting blocks 203 is manually bent to deflect it. Because the hinge shafts 2031 of several limiting blocks 203 are meshed with a gear and a rack on one side of the transmission rod 2032, when one limiting block 203 is manually deflected, it will cause several limiting blocks 203 to deflect together. By adjusting the two sides... When one of the limiting blocks 203 is deflected by force, several limiting blocks 203 on both sides of the middle of the observation opening 204 will deflect and retract together. Then the observation block 202 will lose its restraint and will be pulled back to its original position by the spring in the telescopic rod 2022. If the curvature of the body 1 has been adjusted, the observation block 202 will directly return to its original position and abut against one end of the observation opening 204. If not, it proves that there is still curvature that has not been adjusted. This is to facilitate the detection of the parallelism of the body 1 and to facilitate the correction of the curvature of the body 1.

[0035] The following is a specific implementation process of the present invention. First, the front end of the main body 1 is connected to the inside of the start-up furnace. Then, the atomized oil sprayed from the oil gun 102 inside the main body 1 is ignited by the ignition device, thereby igniting and heating the start-up furnace. When the oil gun 102 sprays the oil, high-pressure gas is injected through the high-pressure gas inlet 103. Then, the high-pressure gas impacts the sprayed oil, further breaking and atomizing the oil, making the oil sprayed from the main body 1 more thoroughly atomized to facilitate ignition.

[0036] Meanwhile, when the part of the main body 1 located inside the start-up / shutdown furnace bends due to uneven heating, the fixing block 201 near the oil gun 102 in the cavity 2 will shift due to the bending, causing the thread between the fixing block 201 and the observation block 202 to lengthen. Therefore, when the main body 1 bends, the fixing block 201 will exert a certain force on the traction cable 2021 to pull the observation block 202 along the cavity 2. The movement range of the observation block 202 is within the observation opening 204, which is located outside the start-up / shutdown furnace. Therefore, when the observation block 202 is dragged and moved, it can be directly seen through the observation opening 204 to promptly know whether the part of the main body 1 located inside the start-up / shutdown furnace has bent. This avoids the situation inside the start-up / shutdown furnace not being known in time when the bending is slight, which could lead to the bending becoming more severe and making it impossible to pull the main body 1 out of the start-up / shutdown furnace.

[0037] Simultaneously, when the observation block 202 is located in the observation opening 204, one side of the observation block 202 will abut against the limiting block 203 in the deflection grooves 205 on both sides of the middle of the observation opening 204. The "L" shape of the limiting block 203 itself causes the longer part of the limiting block 203 to protrude on the deflection groove 205, so that one side of the observation block 202 will fit against the protruding part of the limiting block 203. This prevents the observation block 202 from sliding confidently in the observation opening 204 when it is not being pulled. At the same time, the limiting block 203 is connected to the deflection groove 205 through the hinge shaft 2031. Through the torsion spring of the hinge shaft 2031, the limiting block 203 will not easily deflect on its own, thus allowing the limiting block 203 to abut and limit the observation block 202.

[0038] Several limiting blocks 203 set on both sides of the middle of the observation opening 204 can form a limiting abutment at the corresponding part of the pulled position when the observation block 202 is bent and pulled due to the displacement of the main body 1 to start and stop the furnace. This prevents the observation block 202 from sliding a certain distance on its own after being pulled, which would make it impossible to accurately know the degree of bending. The distance that the observation block 202 is pulled can be known through the scale 2041, so as to accurately know the degree of bending of the main body 1, so that it can be removed and adjusted in time when the degree of bending affects the removal and disassembly.

[0039] Finally, one end of the observation block 202 is connected to the middle end of the observation opening 204 via a telescopic rod 2022. When the main body 1 is found to be bent and promptly removed for adjustment, one of the limiting blocks 203 is manually bent to deflect it. Because the hinge shafts 2031 of several limiting blocks 203 are meshed with a gear and a rack on one side of the transmission rod 2032, when one limiting block 203 is manually deflected, it will cause several limiting blocks 203 to deflect together. By adjusting the two sides... When one of the limiting blocks 203 is deflected by force, several limiting blocks 203 on both sides of the middle of the observation opening 204 will deflect and retract together. Then the observation block 202 will lose its restraint and will be pulled back to its original position by the spring in the telescopic rod 2022. If the curvature of the body 1 has been adjusted, the observation block 202 will directly return to its original position and abut against one end of the observation opening 204. If not, it proves that there is still curvature that has not been adjusted. This is to facilitate the detection of the parallelism of the body 1 and to facilitate the correction of the curvature of the body 1.
