Description

Technical Field

[0001] This utility model relates to the field of burner technology, specifically to a boiler burner. Background Technology

[0002] Boiler burners operate under high temperature and high pressure environments for extended periods. Especially when using fuels with high viscosity or high impurity content, such as heavy oil, bio-oil, or waste oil, the fuel is prone to pyrolysis, oxidation, and polymerization reactions during combustion. This leads to the formation of stubborn carbon deposits and coking compounds inside the burner head (e.g., nozzles, flame stabilizers, mixing chambers). These deposits gradually clog fuel channels, impair atomization, reduce combustion efficiency, and may cause flame instability, increased NOx emissions, and even safety accidents such as flameout or deflagration.

[0003] To ensure the normal operation of the burner, regular maintenance and cleaning are crucial. Traditional cleaning methods mainly rely on manually disassembling the burner head and then cleaning it using wire brushes, scrapers, high-pressure air purging, or chemical soaking. Manual cleaning is inefficient, leading to long equipment downtime and affecting production. Moreover, the cleaning effect is not ideal, with limited ability to remove firmly attached coke, and carbon deposits are easily left behind. Uneven force or improper use of tools during operation can easily scratch the inner wall of the nozzle and damage precision components such as the flame stabilizer.

[0004] To address these issues, a boiler burner is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a boiler burner that solves the problem of carbon buildup caused by fuel coking during long-term operation of boiler burners. Existing technologies rely on manual cleaning, which has the problems of low efficiency, high labor intensity and incomplete cleaning.

[0006] This utility model achieves the above objectives through the following technical solutions: A boiler burner, comprising: The burner head is equipped with a connecting flange for docking with the boiler. A cleaning component, fitted around the outer periphery of the burner head and located on the side of the connecting flange away from the boiler, is used to clean and inspect the internal channels of the burner head. The cleaning component includes: A fixing plate is fixedly installed on the outer wall of the boiler; A rotating plate is rotatably mounted on the fixed plate, and two mounting cylinders are integrally formed on the rotating plate; An ultrasonic adsorption component and a visual inspection component are provided, both of which are designed as telescopic structures and housed within corresponding mounting cylinders. A motor is fixedly mounted on the fixed plate, and its output end is fixedly connected to the rotating plate. It is used to drive the rotating plate to rotate when the burner head is pulled out of the boiler to the maintenance position so that the ultrasonic adsorption component and the visual inspection component are sequentially aligned coaxially with the burner head.

[0007] As a further optimization of this utility model, a positioning hole is provided on the outer wall of the end of the burner head, and a positioning component adapted to the positioning hole is provided on the fixing plate for positioning the burner head pull-out position; the positioning component includes a fixing seat, a positioning rod that movably passes through the fixing seat, and a fastener provided on the side of the fixing seat for locking the positioning rod.

[0008] As a further optimization of this utility model, the fixing plate is provided with fixing holes for fixed connection with the outer wall of the boiler and a first through hole for the burner head to pass through; the rotating plate is provided with a second through hole for the burner head to pass through.

[0009] As a further optimization of this utility model, the ultrasonic adsorption assembly includes a first electric push rod, a mounting plate fixedly disposed at the movable end of the first electric push rod, a mounting frame disposed on the mounting plate, and an ultrasonic vibrator fixedly disposed within the mounting frame; the output end of the ultrasonic vibrator is fixedly provided with a transmission frame adapted to the internal contour of the combustion head, the surface of the transmission frame is provided with a plurality of grooves, each groove is embedded with a vibrating bead, and a second spring is provided between the vibrating bead and the bottom of the groove.

[0010] As a further optimization of this utility model, a plurality of buffer units are provided between the mounting plate and the mounting frame; the buffer unit includes a movable rod fixedly mounted on the mounting frame, the movable rod movably passing through the mounting plate, and a limiting block is fixedly provided at its end, and a first spring is sleeved on the movable rod between the limiting block and the mounting plate.

[0011] As a further optimization of this utility model, the transmission frame is also integrated with an adsorption unit for adsorbing particulate impurities inside the combustion head during the vibration of the vibrating beads; the adsorption unit includes multiple adsorption holes opened on the surface of the transmission frame, an adsorption pump fixed on the mounting frame, and an ash collection box, and the adsorption pump is connected to the adsorption holes through an adsorption pipeline.

[0012] As a further optimization of this utility model, a movable door is provided on the mounting cylinder at the position corresponding to the ash collection box.

[0013] As a further optimization of this utility model, the visual inspection component includes a second electric push rod and a camera fixedly mounted on the movable end of the second electric push rod; the camera is provided with multiple supplementary lights around its periphery.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model uses a rotating plate to align the ultrasonic adsorption component and the visual inspection component coaxially with the burner head in sequence. The telescopic structure extends axially into the internal channel of the burner head to perform cleaning and inspection operations respectively, realizing automatic switching and sequential execution of maintenance functions, significantly improving maintenance efficiency and automation.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1 To address the carbon buildup problem in boiler burners caused by fuel coking during long-term operation, current technologies rely on manual cleaning, which is inefficient, labor-intensive, and incompletely cleans the burners. Please refer to [link / reference needed]. Figures 1-2 The present invention provides a boiler burner comprising: The burner head 1 is provided with a connecting flange 101 for docking with the boiler; A cleaning component is fitted around the outer periphery of the burner head 1 and located on the side of the connecting flange 101 away from the boiler. It is used to clean and inspect the internal channels of the burner head 1. The cleaning components include: The fixing plate 2 is fixedly installed on the outer wall of the boiler. The fixing plate 2 is provided with fixing holes 201 for fixed connection with the outer wall of the boiler and a first through hole 202 for the burner head 1 to pass through. Rotating plate 4 is rotatably mounted on fixed plate 2. Two mounting cylinders 401 are integrally formed on rotating plate 4, and a second through hole 402 for the combustion head 1 to pass through is also provided on it. The ultrasonic adsorption component 5 and the visual inspection component 6 are both designed as telescopic structures and are housed within the corresponding mounting cylinder 401. The motor 7 is fixedly mounted on the fixed plate 2, and its output end is fixedly connected to the rotating plate 4. It is used to drive the rotating plate 4 to rotate so that the ultrasonic adsorption component 5 and the visual inspection component 6 are aligned coaxially with the burner head 1 in sequence when the burner head 1 is pulled out of the boiler to the maintenance position.

[0020] The burner head 1 has a positioning hole 102 on its outer end wall, and the fixing plate 2 has a positioning element 3 that matches the positioning hole 102 for positioning the burner head 1 when it is pulled out. The positioning element 3 includes a fixing base 301, a positioning rod 302 that moves through the fixing base 301, and a fastener 303 on the side of the fixing base 301 for locking the positioning rod 302. By providing a positioning hole 102 at the end of the burner head 1 and cooperating with the positioning element 3 on the fixing plate 2, the burner head 1 can be quickly and accurately positioned after being pulled out, ensuring that the cleaning components can be accurately aligned during each maintenance, and avoiding probe collision or uneven cleaning due to assembly deviation.

[0021] like Figures 3-5As shown, the ultrasonic adsorption assembly 5 includes a first electric push rod 501, a mounting plate 502 fixedly disposed at the movable end of the first electric push rod 501, a mounting bracket 503 disposed on the mounting plate 502, and an ultrasonic vibrator 504 fixedly disposed within the mounting bracket 503; the output end of the ultrasonic vibrator 504 is fixedly provided with a transmission frame 505 adapted to the internal contour of the combustion head 1, the surface of the transmission frame 505 is provided with a plurality of grooves, each groove is embedded with a vibrating bead 506, and a second spring 513 is provided between the vibrating bead 506 and the bottom of the groove to enhance the vibration effect.

[0022] The transmission frame 505 also integrates an adsorption unit for adsorbing particulate impurities inside the burner head 1 during the vibration of the vibrating bead 506. The adsorption unit includes multiple adsorption holes 509 opened on the surface of the transmission frame 505, an adsorption pump 507 fixed on the mounting frame 503, and an ash collection box 508. The adsorption pump 507 is connected to the adsorption holes 509 through an adsorption pipeline. A movable door 403 is opened on the mounting cylinder 401 at the position corresponding to the ash collection box 508.

[0023] When the ultrasonic adsorption assembly 5 is working, the first electric push rod 501 drives the mounting plate 502 and mounting bracket 503 to extend into the burner head 1, and the transmission frame 505 moves forward accordingly. Under the elastic force of the second spring 513, the vibrating bead 506 is tightly attached to the inner wall of the burner head 1. After the ultrasonic vibrator 504 is started, the vibration energy is transmitted to the vibrating bead 506 through the transmission frame 505. The vibrating bead 506 vibrates at high frequency to break up the ash and coke residue accumulated on the inner wall. The second spring 513 can compensate for the small unevenness of the inner wall of the burner head 1 to ensure that the vibrating bead 506 is always in contact. During the process, the adsorption pump 507 is started, and a negative pressure is formed inside the burner head 1 through the adsorption pipeline and adsorption hole 509. The broken particles enter the ash collection box 508 for collection through the adsorption hole 509 and pipeline. After cleaning, the first electric push rod 501 retracts and resets, and the movable door 403 of the mounting cylinder 401 can be opened to remove the ash collection box 508 to clean the particles.

[0024] like Figure 6 As shown, the visual inspection component 6 includes a second electric push rod 601 and a camera 602 fixedly mounted on the movable end of the second electric push rod 601; a plurality of supplementary lights 603 are provided around the camera 602.

[0025] During use, the boiler burner is stopped, and the fuel and power supply are cut off. After the temperature of the burner head 1 drops to a safe operating range, the fixing bolts on the connecting flange 101 are removed, and the burner head 1 is pulled out axially from the boiler furnace as a whole. The positioning hole 102 on the outer wall of its end is aligned with the positioning piece 3 on the fixing plate 2. The positioning rod 302 is inserted into the positioning hole 102 to achieve precise positioning of the burner head 1 in the axial and circumferential directions. The positioning rod 302 is then locked with fasteners 303 (such as knobs or screws). The motor 7 is started to drive the rotating plate 4 to rotate. The ultrasonic adsorption component 5 is rotated to a position coaxial with the burner head 1, extending into the internal channel of the burner head 1. Through high-frequency vibration, the carbon deposits and coke adhering to the inner wall of the burner head 1 are loosened. The loosened particles are immediately sucked in by the negative pressure airflow. After cleaning, the ultrasonic adsorption component 5 is reset, the motor 7 is restarted, and the rotating plate 4 is driven to rotate, so that the mounting cylinder 401 equipped with the vision inspection component 6 is rotated to a position coaxial with the burner head 1, and high-definition images of the internal channel of the burner head 1 are collected to evaluate the cleaning effect.

[0026] Example 2 Based on Embodiment 1, in order to avoid excessive compression of the internal components of the burner head 1, such as Figure 3 As shown, multiple buffer units are provided between the mounting plate 502 and the mounting bracket 503; the buffer unit includes a movable rod 510 fixedly mounted on the mounting bracket 503, the movable rod 510 movably passes through the mounting plate 502, and a limiting block 511 is fixedly provided at its end, and a first spring 512 is sleeved on the movable rod 510 between the limiting block 511 and the mounting plate 502.

[0027] When the first electric push rod 501 drives the mounting plate 502 to extend the ultrasonic vibrator 504 and its front-end transmission frame 505 into the burner head 1, the vibrating beads 506 on the surface of the transmission frame 505 need to maintain appropriate contact with the inner wall of the burner head 1 or internal components (such as flame stabilizer, nozzle guide fluid, etc.) to transmit ultrasonic vibration energy and loosen carbon deposits; when the vibrating beads 506 squeeze the internal components, the mounting frame 503 can retract slightly along the axial direction of the movable rod 510 to compress the first spring 512, thereby achieving buffering and avoiding rigid compression.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
