Description

Technical Field

[0001] The utility model relates to the technical field of boiler soot blowers, in particular to a long telescopic soot blower. Background Art

[0002] Sootblowers are commonly used in the boiler industry, primarily for removing accumulated ash from the boiler's heating surfaces. They typically include steam sootblowers and sonic sootblowers. Steam sootblowers utilize the impact of high-speed jets of superheated steam to remove accumulated ash from the boiler's heating surfaces. They operate in high-temperature and high-pressure environments, resulting in high energy consumption during the cleaning process. Sonic sootblowers, on the other hand, convert compressed air into high-power sound waves and inject them into the furnace. When the accumulated ash on the boiler's heating surface is repeatedly pulled and compressed by alternating density waves at a certain frequency, the accumulated ash becomes loose due to fatigue and is carried away by the flue gas flow, or, under the action of gravity, settles into the ash hopper for discharge.

[0003] However, a common design limitation of sonic sootblowers currently on the market is their fixed length. This can lead to practical problems: if the sonic sootblowers fail to fully extend into the boiler inlet, the cleaning effect will be weakened, affecting overall operational efficiency. Furthermore, given the sootblowers' inherent ability to eliminate coke without requiring a shutdown, operators often face high temperatures and close contact with the boiler, which undoubtedly increases the risk and difficulty of the operation. Utility Model Content

[0004] In order to solve the deficiencies mentioned in the above-mentioned background technology, the purpose of the present invention is to provide a long telescopic sootblower. By setting the design of a telescopic extension tube, the sootblower can penetrate into different depths inside the boiler to ensure that the accumulated ash is completely removed, and by pulling the movable tube, the primary tube, secondary tube and movable tube are synchronously extended and retracted, so that the telescopic action amplitude is larger and the action is faster. The length of the sootblower can be adjusted according to the actual conditions of different boilers, thereby improving the versatility and flexibility of the equipment.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A telescopic sootblower comprises a sound wave generator and a sound wave outlet pipe, with a telescopic extension pipe disposed between the two. The telescopic extension pipe comprises a primary pipe, a secondary pipe, and a movable pipe, the diameters of which decrease in sequence. The secondary pipe is located within the primary pipe, and the movable pipe is located within the secondary pipe. The outer wall of the secondary pipe mates with the inner wall of the primary pipe, and the outer wall of the movable pipe mates with the inner wall of the secondary pipe. This eliminates the need for operators to come into close contact with high-temperature boilers, reducing operational risks.

[0007] Primary pipe: fixedly connected to the acoustic wave generator and serving as the main support part of the extension pipe.

[0008] Movable pipe: connected to the acoustic wave outlet pipe and capable of telescoping to a specified position inside the boiler as needed in cooperation with the secondary pipe.

[0009] Further preferably, the primary pipe is connected to the acoustic wave generator, and the movable pipe is connected to the acoustic wave outlet pipe.

[0010] Further preferably, a first groove is provided on the outer surface of the wall of the secondary pipe, rotating shafts are symmetrically arranged inside the first groove, a second groove is provided on the inner surface of the wall of the secondary pipe, one end of the rotating shaft passes through the wall of the secondary pipe and extends into the second groove, and both ends of the rotating shaft are sleeved with gear wheels, and the two gear wheels are respectively located inside the first groove and the second groove.

[0011] Further preferably, toothed drive belts are provided inside both the first groove and the second groove. The two gear wheels in the first groove are drivingly connected through the toothed drive belt, and the two gear wheels in the second groove are drivingly connected through the toothed drive belt. Through the cooperation of the gear wheels and the drive belt, synchronous telescoping between the secondary pipe and the movable pipe is achieved.

Connecting blocks are provided on both the inner wall of the primary pipe and the outer wall of the movable pipe, and these connecting blocks are respectively fixedly connected to the toothed drive belts inside the first groove and the second groove to ensure the synchronism and stability of the telescoping action. The connection positions of the connecting blocks and the drive belt adopt a symmetrical design to balance the telescoping force, improve the stability of the overall structure, and simultaneously achieve synchronous telescoping among the primary pipe, the secondary pipe, and the movable pipe.

[0014] Advantages of the present utility model:

[0015] 1. Through the design of the telescopic extension pipe in the present utility model, the soot blower can reach different depths inside the boiler, ensuring that the ash deposit is comprehensively removed.

[0028] Movable pipe 5: It is connected to the sound wave outlet pipe 2 and can be telescoped to a specified position inside the boiler as needed in cooperation with the secondary pipe.

[0029] The primary pipe 3 is connected to the sound wave generator 1, and the movable pipe 5 is connected to the sound wave outlet pipe 2.

[0030] A first groove 6 is formed on the outer surface of the wall of the secondary pipe. Rotating shafts 7 are symmetrically arranged inside the first groove 6.

Gear wheels 9 are sleeved at both ends of the rotating shaft 7, and the two gear wheels 9 are respectively located inside the first groove 6 and the second groove 8.

[0031] Toothed drive belts 10 are arranged inside both the first groove 6 and the second groove 8. The two gear wheels 9 in the first groove 6 are drivingly connected through the toothed drive belt 10, and the two gear wheels 9 in the second groove 8 are drivingly connected through the toothed drive belt 10. Through the cooperation of the gear wheels 9 and the drive belt, synchronous telescoping between the secondary pipe and the movable pipe 5 is achieved.

[0032] Connecting blocks 11 are arranged on the inner wall of the primary pipe 3 and the outer wall of the movable pipe 5. The connecting block 11 on the primary pipe 3 is fixedly connected to the toothed drive belt 10 inside the first groove 6, and the connecting block 11 on the movable pipe 5 is fixedly connected to the toothed drive belt 10 inside the second groove 8.

[0035] Adjust the telescopic extension pipe through the manual control device so that the movable pipe 5 extends into the specified position inside the boiler.

[0036] When adjusting the length, pull the movable pipe 5, causing a displacement between the movable pipe 5 and the secondary pipe. Then, the toothed drive belt 10 will be driven through the connection block 11, and another toothed drive belt 10 will be driven through the transmission of the gear wheel 9 and the rotating shaft 7. Furthermore, the connection block 11 on the primary pipe 3 will be pulled. Since the connection positions of the two connection blocks 11 and the toothed drive belt 10 are symmetrically arranged, the displacements between the movable pipe 5 and the primary pipe 3 and the secondary pipe are in a relative state.

[0037] The acoustic waves are transmitted to the acoustic wave outlet pipe 2 through the telescopic extension pipe and act on the ash deposits on the heating surface of the boiler.

[0038] The ash deposits are loosened and fall off under the repeated pulling and pressing action of the acoustic waves, and are carried away by the flue gas flow or sink to the ash hopper and discharged.

[0039] After the ash cleaning is completed, retract the telescopic extension pipe through the external control device and turn off the acoustic wave generator 1.
