Description

Technical Field

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

[0002] A boiler soot blower is a specialized device used to remove ash or slag buildup on the heating surfaces of a boiler. When a boiler burns fuel, ash and unburned particles in the flue gas adhere to the heating surfaces, forming ash or slag deposits. These deposits reduce heat exchange efficiency, increase energy consumption, and may even cause safety hazards such as corrosion, ash blockage, or tube rupture. The role of the soot blower is to remove ash through physical or chemical means, ensuring the efficient and safe operation of the boiler.

[0003] Existing boiler soot blowers can complete the soot blowing operation inside the boiler during use. However, the position of the bell mouth of the existing soot blowing tube is fixed during the soot blowing process, which limits the soot blowing range and makes it difficult to blow soot evenly inside the boiler. Therefore, a boiler soot blower is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a boiler soot blower with advantages such as the ability to change the angle of the soot blowing tube, thereby improving the overall soot blowing effect. It solves the problem that existing boiler soot blowers can complete soot blowing operations inside the boiler, but the position of the bell mouth of the existing soot blowing tube is fixed during the soot blowing process, resulting in a limited soot blowing range and difficulty in unevenly blowing soot inside the boiler.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figure 1-4 The present invention discloses a boiler soot blower, comprising a boiler shell 1 and an ultrasonic generating component 2 fixedly installed on the outside of the boiler shell 1 via a support base. A loudspeaker 4 is rotatably installed on the inside of the boiler shell 1 via a hinge support. A connecting base 11 is fixedly installed on the inside of the boiler shell 1. A threaded transmission rod 6 is rotatably connected to the inside of the connecting base 11 via a transmission component 7. An adjusting rod 9 is threadedly connected to the outer periphery of the threaded transmission rod 6. The top of the adjusting rod 9 passes through a limiting shell 8 at the top of the connecting base 11 and is slidably connected to the inside of the limiting shell 8. The top of the adjusting rod 9 is hinged to the bottom of the loudspeaker 4 via a sliding component 10.

[0026] Precise lifting control is achieved through the threaded engagement of the threaded transmission rod 6 and the adjusting rod 9. The rectangular guide channel of the limiting shell 8 ensures the linear movement of the adjusting rod 9. The angle adjustment of the loudspeaker 4 can optimize the sound wave coverage range and improve the soot blowing efficiency.

[0027] The boiler shell 1 has a pipe installer 3 fixedly installed inside. One end of the pipe installer 3 is connected to the ultrasonic generator 2, and the other end is connected to the loudspeaker 4 through the hose 5. The ultrasonic generator 2, the pipe installer 3, the hose 5 and the loudspeaker 4 are connected in sequence to form a sound wave conduction path.

[0028] The high-pressure sound waves generated by the ultrasonic generator 2 are transmitted to the hose 5 through the pipe installer 3. The hose 5 flexibly transmits the sound waves to the loudspeaker 4. The loudspeaker 4 amplifies the sound waves in a direction and then acts on the inner wall of the boiler.

[0029] The flexible connection of the hose 5 adapts to the angle adjustment of the loudspeaker 4, avoiding leakage or fatigue damage to the rigid pipe due to angle changes, and ensuring the stability and durability of the sound wave transmission path.

[0030] The ultrasonic generating component 2 includes a high-pressure gas source device 21, an ultrasonic transducer 22 connected to the outlet of the high-pressure gas source device 21, and a sound wave output pipe 23 connecting the ultrasonic transducer 22 and the pipe installer 3. The high-pressure gas source device 21 is fixedly installed on the upper platform of the support base, and the sound wave output pipe 23 is connected to the pipe installer 3 through a flange connector to form a detachable sealed connection.

[0031] The high-pressure gas source device 21 provides compressed gas to the ultrasonic transducer 22, which converts the gas energy into high-frequency sound waves. The sound wave output pipe 23 transmits the sound waves to the pipe installer 3 through a flange connection. The flange connection facilitates the disassembly and maintenance of the sound wave output pipe 23.

[0032] The transmission assembly 7 includes a transmission worm gear 71, a transmission worm 72, and a transmission motor 73. The transmission motor 73 is fixedly installed on the top of the support base, and its output shaft is fixedly installed on the outside of the transmission worm 72. The transmission worm gear 71 is fixedly installed on the outside of the threaded transmission rod 6, and it meshes with the outside of the transmission worm 72.

[0033] The drive motor 73 drives the drive worm 72 to rotate, and the drive worm 72 meshes with the drive worm wheel 71 to drive the threaded drive rod 6 to rotate, thereby driving the adjusting rod 9 to rise and fall;

[0034] The worm gear drive has a self-locking function, which can prevent the adjusting rod 9 from shifting due to gravity or vibration, and ensure the positional stability of the loudspeaker 4 after angle adjustment.

[0035] The sliding assembly 10 includes two limiting slide plates 101 fixedly connected to the outside of the loudspeaker 4. A connecting block 103 is slidably connected between the two limiting slide plates 101 through a T-shaped limiting rod 102. The bottom end of the connecting block 103 is rotatably connected to the top end of the adjusting rod 9 through a hinge support.

[0036] The connecting block 103 slides along the T-shaped limiting rod 102, and at the same time, it is rotatably connected to the top of the adjusting rod 9 through the hinge support, so that the loudspeaker 4 maintains linkage with the adjusting rod 9 during the angle adjustment process.

[0037] The T-shaped limiting rod 102 restricts the sliding trajectory of the connecting block 103 to prevent the loudspeaker 4 from shifting during rotation. The hinged design allows for compound motion between the adjusting rod 9 and the loudspeaker 4.

[0038] Among them, the limiting shell 8 is a rigid shell with a rectangular guide channel, and its inner wall is in clearance fit with the outer peripheral surface of the adjusting rod 9. The cross-sectional shape of the adjusting rod 9 is a polygonal column structure adapted to the rectangular guide channel.

[0039] The rectangular guide channel of the limiting shell 8 matches the polygonal cross section of the adjusting rod 9, so that the adjusting rod 9 can only slide in the vertical direction, and the clearance fit reduces frictional resistance.

[0040] The combination of the polygonal column structure and the rectangular guide channel effectively prevents the adjustment rod 9 from rotating, ensuring the linearity of the lifting movement. The clearance fit reduces wear and increases service life.

[0041] Working principle:

[0042] When boiler soot blowing is required, the high-pressure sound waves generated by the ultrasonic generator 2 are transmitted to the hose 5 through the pipe installer 3. The hose 5 flexibly transmits the sound waves to the loudspeaker 4, and the loudspeaker 4 amplifies the sound waves in a direction and then acts on the inner wall of the boiler.

[0043] During the soot blowing process, the drive motor 73 is started to drive the drive worm 72 to rotate. The drive worm 72 meshes with the drive worm wheel 71 to drive the threaded drive rod 6 to rotate, which in turn drives the adjusting rod 9 to rise and fall, thereby allowing the loudspeaker 4 to move up and down, improving the overall soot blowing effect.
