Description

Technical Field

[0001] The invention relates to the technical field of boiler acoustic wave ash cleaning, in particular to a movable hanger for an acoustic wave generator. Background Art

[0002] In existing boiler acoustic wave cleaning systems, the acoustic wave generator is typically rigidly mounted directly to the boiler's outer wall. However, during boiler operation, thermal expansion due to high temperatures can cause the acoustic wave generator to move horizontally and vertically. If the acoustic wave generator is completely fixed, mechanical stress will be transmitted through the sound transmission pipe. Long-term stress can easily cause problems such as weld cracking, shortening the equipment life. Therefore, we designed a movable hanger for the acoustic wave generator. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above problems or at least partially solve the above problems, and to propose a movable hanger for an acoustic wave generator.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a movable hanger for an acoustic wave generator, comprising a track beam arranged on the outer wall of a boiler, a pulley assembly capable of lateral displacement thereof being provided on the track beam, and limit members being provided on the track beams on both sides of the pulley assembly for limiting the range of movement of the pulley assembly, a pull rod being provided below the pulley assembly, a sound wave generator being provided below the pull rod, an elastic telescopic member allowing longitudinal movement being provided between the pull rod and the sound wave generator, a sound transmission pipe being provided at the output end of the sound wave generator, and the sound transmission pipe passing through the outer wall of the boiler.

[0005] In a preferred embodiment, the track beam is arranged in an I-shape.

[0006] In a preferred embodiment, the pulley assembly includes a pulley and a connecting frame in a "concave" shape, and pulleys are rotatably provided on both sides of the inner wall of the connecting frame. The number of the pulleys on each side along the horizontal direction is at least two, and the lower surface of the pulley is placed on the inner wall of the track beam.

[0007] In a preferred embodiment, the limiting member is a limiting screw, and the limiting screw is screwed onto the track beam.

[0008] In a preferred embodiment, a turnbuckle tensioner is further provided between the elastic expansion member and the sound wave generator.

[0009] In a preferred embodiment, the elastic telescopic member is a telescopic spring.

[0010] In a preferred embodiment, a hanging ring is provided on the top of the acoustic wave generator, the bottom end of the turnbuckle tensioner is hung in the hanging ring, and the top end thereof is hung on the bottom end of the telescopic spring.

[0011] In a preferred embodiment, a diagonal brace plate is obliquely provided at one end of the bottom middle portion of the track beam and outside the limit screw, and the other end of the diagonal brace plate is connected to the outer wall of the boiler.

[0012] In a preferred embodiment, the head of the limit screw is also wrapped with a high-temperature resistant buffer layer.

[0013] In a preferred embodiment, at room temperature, the rolling resistance of the pulley assembly is smaller than the lateral force component generated by the weight of the acoustic wave generator.

[0014] Compared with the prior art, the present invention provides a movable hanger for an acoustic wave generator, which solves the problem that the traditional rigid fixing method cannot adapt to the equipment stress caused by the thermal expansion of the boiler through the cooperation of the pulley assembly and the elastic telescopic part. The pulley assembly slides on the track beam to absorb the lateral expansion, and the cooperation of the elastic telescopic part and the basket screw tensioner can absorb the longitudinal expansion, which significantly improves the adaptability of the acoustic wave generator under the thermal expansion condition of the boiler, avoids the problems of deformation of the sound transmission pipe and cracking of the weld caused by the traditional fixing method, and significantly improves the service life and reliability of the equipment.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this description, those skilled in the art may make creative modifications to the embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0023] The present invention provides a movable hanger for an acoustic wave generator, which solves the technical problems in the prior art. The overall idea is as follows:

[0024] Example 1:

[0025] See also Figure 1-Figure 5 ; A movable hanger for an acoustic wave generator includes a track beam 2 arranged on the outer wall 1 of a boiler, the track beam 2 is arranged in an "I" shape, a pulley assembly 3 capable of lateral displacement thereof is provided on the track beam 2, and limiting members are provided on the track beam 2 on both sides of the pulley assembly 3, the limiting members are limit screws 4, the limit screws 4 are screwed on the track beam 2, and are used to limit the moving range of the pulley assembly 3, a pull rod 5 is provided below the pulley assembly 3, and an acoustic wave generator 8 is provided below the pull rod 5, an elastic telescopic member allowing longitudinal movement is provided between the pull rod 5 and the acoustic wave generator 8, a sound transmission pipe 10 is provided at the output end of the acoustic wave generator 8, and the sound transmission pipe 10 passes through the outer wall 1 of the boiler, sliding through the pulley assembly 3 laterally to absorb the expansion, and buffering through the elastic telescopic member longitudinally to achieve omnidirectional release of thermal stress.

[0026] In specific implementation, the pulley assembly 3 includes a pulley 32 and a connecting frame 31 in the shape of a "concave". Pulleys 32 are rotatably provided on both sides of the inner wall of the connecting frame 31. The number of pulleys 32 on each side in the horizontal direction is at least two. The lower surface of the pulley 32 is placed on the inner wall of the track beam 2. The symmetrical arrangement of the double pulleys can evenly distribute the load, reduce the contact stress of a single wheel, and also ensure that the pulley 32 maintains stable contact with the track beam 2.

[0027] During specific implementation, a basket screw tensioner 7 is also provided between the elastic telescopic part and the sound wave generator 8. The elastic telescopic part is a telescopic spring 6. A hanging ring 9 is provided on the top of the sound wave generator 8. The bottom end of the basket screw tensioner 7 is hung in the hanging ring 9, and its top end is hung on the bottom end of the telescopic spring 6. The basket screw tensioner 7 realizes bidirectional length adjustment by rotating the middle threaded sleeve, thereby accurately controlling the hanging height of the sound wave generator 8, playing a tightening role and ensuring the installation balance of the sound wave generator 8.

[0028] In specific implementation, one end of a diagonal support plate 11 is obliquely provided at the middle of the bottom end of the track beam 2 and outside the limit screw 4 , and the other end of the diagonal support plate 11 is connected to the outer wall 1 of the boiler to support the track beam 2 .

[0029] In specific implementation, the head of the limit screw 4 is also wrapped with a high-temperature resistant buffer layer to effectively absorb the impact energy when the pulley assembly 3 hits the limit.

[0030] During specific implementation, at room temperature, the rolling resistance of the pulley assembly 3 is less than the lateral component of force generated by the deadweight of the acoustic wave generator 8, which facilitates the low-friction sliding of the sliding assembly 3 on the track beam 2, ensuring that the pulley assembly 3 can automatically slide to compensate for thermal expansion displacement during the heating process of the boiler.

[0031] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific operation is as follows:

[0032] When the boiler starts and heats up, the outer wall 1 of the boiler expands in all directions due to the heat, driving the track beam 2 to move laterally, and the pulley assembly 3 rolls on the track beam 2. Since the rolling resistance of the sliding assembly 3 is less than the lateral component force generated by the deadweight of the sound wave generator 8, automatic slip compensation can be achieved; when the outer wall 1 of the boiler expands longitudinally, the telescopic spring 6 extends to avoid the rigid transmission of stress by the pull rod 5; when the displacement approaches the designed maximum value, the limit screw 4 blocks the pulley assembly 3 from continuing to move, preventing the sound transmission pipe 10 from excessive deviation.

[0033] The above description of the embodiments is to facilitate ordinary technicians in this technical field to understand and use the present invention. It is obvious that those familiar with the technology in this field can easily make various modifications to the embodiments and apply the general principles described herein to other embodiments without having to engage in creative work. Therefore, the present invention is not limited to the above-mentioned embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
