Description

Technical Field

[0001] This disclosure relates to the field of petrochemical technology, and more specifically, to a muffler connection device and a muffler. Background Technology

[0002] Vent silencers used in petrochemical plants are typically installed at the highest point of the plant or structure near the equipment to avoid the influence of medium noise and temperature hazards. To resist dynamic loads such as wind loads and seismic loads and to ensure their own stability, silencers are usually installed in a fixed manner. The pipeline system to which they are connected needs to use natural compensation or compensator compensation to achieve the necessary flexibility of the pipeline system and ensure the safe operation of the pipeline system.

[0003] Typically, the vent pipe and the bottom inlet pipe of the silencer body are rigidly connected. Because the vent pipe will experience large temperature changes during use, it will cause strong thermal expansion and contraction, generating great thermal stress at the rigid connection, which may even lead to failure or damage to the pipeline system or equipment.

[0004] However, as petrochemical plants continue to grow in size, the diameter of venting pipelines is constantly increasing, and the size and weight of silencers are also increasing significantly. Since silencers are installed in a fixed manner, it is very difficult to achieve natural compensation and compensator compensation in the pipeline system connected to them. This requires a lot of space and will increase material costs and construction difficulty. Summary of the Invention

[0005] The purpose of this disclosure is to provide a muffler connection device and a muffler to solve the technical problems existing in the related art.

[0006] To achieve the above objectives, this disclosure provides a muffler connection device for connecting the vent pipe of the muffler body to a housing. The muffler connection device includes a housing, an elastic element, a clamping structure, and a swing sleeve. The housing is used to clamp the vent pipe and is spaced apart from it, and extends vertically. The elastic element is used to tightly fit between the vent pipe and the housing, and allows the vent pipe to move vertically. The clamping structure confines the elastic element within the housing in the vertical direction and compresses it. The swing sleeve is fixedly connected to the housing, clamps the housing, and allows the vent pipe and housing to tilt.

[0007] Optionally, the swing sleeve includes a sleeve body and a baffle. The sleeve body sandwiches the outer shell and is spaced apart from the outer shell in the horizontal direction. The sleeve body is used to be fixedly connected to the outer shell. The baffle is connected to the sleeve body and surrounds the outer shell. The baffle fits against the outer shell and allows the venting connection pipe and the outer shell to tilt and move.

[0008] Optionally, the sleeve body includes a first sleeve, a first positioning plate, and a second sleeve connected sequentially from bottom to top. The first sleeve extends in the vertical direction and is fixedly connected to the housing. The first positioning plate extends in the horizontal direction and has a gap with the housing in the horizontal direction. The second sleeve extends in the vertical direction. The baffle is fixedly connected to the upper end of the second sleeve and extends in the horizontal direction.

[0009] Optionally, the muffler connecting device further includes a second positioning plate, which surrounds and is fixedly connected to the outer wall of the housing. The second positioning plate extends horizontally and is located between the baffle and the first positioning plate. The second positioning plate, the baffle, and the first positioning plate are all spaced apart in the vertical direction. The projection of the second positioning plate in the vertical direction is the second projection, the projection of the first positioning plate in the vertical direction is the first projection, and the projection of the baffle in the vertical direction is the third projection. The second projection partially coincides with the first projection and the third projection.

[0010] Optionally, the clamping structure includes a sealing block, a fixing plate, a clamping sleeve, a clamping disc, and fasteners; the sealing block is fixedly connected to the inner wall of the housing and disposed above the elastic element; the fixing plate is fixedly connected to the outer wall below the housing and extends horizontally; the clamping sleeve is disposed between the venting connection pipe and the housing and leaves a gap with the venting connection pipe; the clamping sleeve extends vertically and its upper end presses against the elastic element; the clamping disc is connected to the lower part of the fixing plate through the fasteners, and the upper surface of the fixing plate presses against the lower end of the clamping sleeve.

[0011] Optionally, the fastener includes a fastening bolt, a fastening nut, and an elastic preload plate. The fastening bolt passes through the pressure plate and the fixing plate from bottom to top and is connected to the fastening nut. The elastic preload plate is capable of elastic deformation in the vertical direction and is disposed between the fastening nut and the fixing plate.

[0012] Optionally, the muffler connecting device further includes a limiting member, which includes a limiting bolt, a first limiting nut, and a second limiting nut. The limiting bolt passes through the limiting plate, the pressure plate, and the fixing plate of the venting connecting pipe from bottom to top. The first limiting nut is connected to the limiting bolt and is used to fit tightly against the upper surface of the limiting plate. The bolt head of the limiting bolt is used to fit tightly against the lower surface of the limiting plate. The end of the limiting bolt away from the pressure plate protrudes from the fixing plate in the vertical direction and is connected to the second limiting nut. The limiting plate surrounds and is fixedly connected to the outer wall of the venting connecting pipe.

[0013] Optionally, the baffle includes a baffle surface in the horizontal direction for conforming to the housing, the baffle surface being configured as an arcuate surface for protruding toward the housing.

[0014] This disclosure also provides a muffler, which includes a muffler body and a muffler connecting device, wherein the muffler body includes a venting connecting pipe and a housing.

[0015] Optionally, the housing includes a housing body and a base plate, the base plate extends horizontally and is connected to the interior of the housing body, the base plate has a mounting hole for the venting connection pipe to pass through, and the swing sleeve of the muffler connection device is fixedly connected to the base plate.

[0016] In the above technical solution, because the elastic element allows the venting connection pipe to move vertically, it enables the venting connection pipe to move vertically. The clamping structure can confine the elastic element within the housing in the vertical direction, preventing the elastic element from detaching from the housing. Furthermore, the clamping structure can compress the elastic element in the vertical direction, thereby ensuring that the elastic element fits tightly between the housing and the venting connection pipe, improving the sealing performance. In addition, the swing sleeve is used for fixed connection to the housing, and the swing sleeve clamps the housing and allows the venting connection pipe and the housing to tilt, which can meet the working conditions of venting connection pipe swaying and avoid the failure of the venting connection pipe connection to the housing.

[0017] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0018] The accompanying drawings are provided to further illustrate the present disclosure and form part of the specification. They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof. In the drawings:

[0020] Figure 2 yes Figure 1 Enlarged view of the lower middle section. Detailed Implementation

[0021] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0022] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" refer only to the upper and lower as defined in the illustrated direction of the muffler, and directional terms such as "horizontal direction" also refer to the horizontal direction as defined in the illustrated direction of the muffler; they do not constitute a limitation on the arrangement direction of the muffler connection device in the use state of this disclosure. Terms such as "first" and "second" are used only to distinguish one element from another and do not have any sequential or important significance.

[0023] Reference Figure 1 and Figure 2 As shown, this disclosure provides a muffler connection device 5 for connecting the vent pipe 3 of the muffler body 1 to the housing 100. The muffler connection device 5 includes a housing 51, an elastic element 55, a clamping structure, and a swing sleeve. The housing 51 is used to clamp the vent pipe 3 and is spaced apart from the vent pipe 3. The housing 51 extends in the vertical direction A. The elastic element 55 is used to tightly fit between the vent pipe 3 and the housing 51, and the elastic element 55 allows the vent pipe 3 to move in the vertical direction A. The clamping structure can confine the elastic element 55 within the housing 51 in the vertical direction A, and the clamping structure can compress the elastic element 55 in the vertical direction A. The swing sleeve is fixedly connected to the housing 100, and the swing sleeve clamps the housing 51 and allows the vent pipe 3 and the housing 51 to tilt and move.

[0024] In the above technical solution, since the elastic element 55 allows the venting connecting pipe 3 to move in the vertical direction A, it allows the venting connecting pipe 3 to move in the vertical direction A. The clamping structure can confine the elastic element 55 within the housing 51 in the vertical direction A, preventing the elastic element 55 from detaching from the housing 51. Furthermore, the clamping structure can compress the elastic element 55 in the vertical direction A, thereby ensuring that the elastic element 55 is tightly fitted between the housing 51 and the venting connecting pipe 3, improving the sealing performance. In addition, the swing sleeve is used for fixed connection to the housing 100, and the swing sleeve clamps the housing 51 and can be used to allow the venting connecting pipe 3 and the housing 51 to tilt, which can meet the working conditions of the venting connecting pipe 3 shaking and prevent the venting connecting pipe 3 from failing to connect to the housing 100.

[0025] In one implementation, reference is made to Figure 1 and Figure 2 As shown, the swing sleeve includes a sleeve body and a baffle 52. The sleeve body sandwiches the outer shell 51 and is spaced apart from the outer shell 51 in the horizontal direction B. The sleeve body is used for fixed connection with the shell 100. The baffle 52 is connected to the sleeve body and surrounds the outer shell 51. The baffle 52 fits against the outer shell 51 and allows the venting connection pipe 3 and the outer shell 51 to tilt and move. The sleeve body is used for fixed connection with the shell 100, improving the stability of the connection. The baffle 52 allows the outer shell 51 and the venting connection pipe 3 to tilt and move, meeting the working conditions of swaying of the venting connection pipe 3.

[0026] Reference Figure 1 and Figure 2 As shown, the sleeve body includes a first sleeve 50, a first positioning plate 58-2, and a second sleeve 54 connected sequentially from bottom to top. The first sleeve 50 extends along the vertical direction A and is fixedly connected to the housing 100. The first positioning plate 58-2 extends along the horizontal direction B and leaves a gap with the outer housing 51 in the horizontal direction B. The second sleeve 54 extends along the vertical direction A, and a baffle 52 is fixedly connected to the upper end of the second sleeve 54 and extends along the horizontal direction B. This sleeve body structure is stable and simple, but this disclosure does not limit the specific structure of the sleeve body.

[0027] In other implementations, refer to Figure 1 and Figure 2 As shown, the muffler connecting device 5 also includes a second positioning plate 58-1. The second positioning plate 58-1 surrounds and is fixedly connected to the outer wall of the housing 51. The second positioning plate 58-1 extends in the horizontal direction B and is located between the baffle 52 and the first positioning plate 58-2. The second positioning plate 58-1, the baffle 52, and the first positioning plate 58-2 are all spaced apart in the vertical direction A. The projection of the second positioning plate 58-1 in the vertical direction A is the second projection, the projection of the first positioning plate 58-2 in the vertical direction A is the first projection, and the projection of the baffle 52 in the vertical direction A is the third projection. The second projection partially coincides with the first and third projections. Therefore, when the housing 51 and the venting connecting pipe 3 tilt and swing, the second positioning plate 58-1 connected to the housing 51 can abut against the baffle 52, thereby limiting the tilt angle of the housing 51 and the venting connecting pipe 3.

[0028] Optionally, refer to Figure 2As shown, the clamping structure includes a sealing block 56, a fixing plate 53, a clamping sleeve 57, a clamping disc 59, and fasteners 6. The sealing block 56 is fixedly connected to the inner wall of the housing 51 and positioned above the elastic element 55. The fixing plate 53 is fixedly connected to the outer wall below the housing 51 and extends horizontally in the direction B. The clamping sleeve 57 is positioned between the venting connecting pipe 3 and the housing 51, leaving a gap with the venting connecting pipe 3. The clamping sleeve 57 extends vertically in the direction A, with its upper end pressing against the elastic element 55. The clamping disc 59 is connected to the lower part of the fixing plate 53 via fasteners 6, and the upper surface of the fixing plate 53 presses against the lower end of the clamping sleeve 57. By adjusting the tightness of the fasteners 6, the position of the clamping disc 59 relative to the elastic element 55 in the vertical direction A is adjusted, thereby adjusting the deformation of the elastic element 55. This clamping structure is simple in design and easy for operators to use.

[0029] In other implementations, refer to Figure 2 As shown, the fastener 6 includes a fastening bolt 61, a fastening nut 62, and an elastic preload plate 63. The fastening bolt 61 passes through the pressure plate 59 and the fixing plate 53 from bottom to top and is connected to the fastening nut 62. The elastic preload plate 63 can elastically deform in the vertical direction A, and the elastic preload plate 63 is disposed between the fastening nut 62 and the fixing plate 53. By setting the elastic preload plate 63, the elastic sealing effect can be further improved.

[0030] Reference Figure 1 and Figure 2 As shown, the muffler connecting device 5 also includes a limiting member 7, which includes a limiting bolt 70, a first limiting nut 71, and a second limiting nut 72. The limiting bolt 70 passes through the limiting plate 58-3, the clamping plate 59, and the fixing plate 53 of the vent connecting pipe 3 from bottom to top. The first limiting nut 71 is connected to the limiting bolt 70 and is used to fit tightly against the upper surface of the limiting plate 58-3. The bolt head of the limiting bolt 70 is used to fit tightly against the lower surface of the limiting plate 58-3. The end of the limiting bolt 70 away from the clamping plate 59 protrudes from the fixing plate 53 in the vertical direction A and is connected to the second limiting nut 72. The limiting plate 58-3 surrounds and is fixedly connected to the outer wall of the vent connecting pipe 3. This can limit the displacement of the vent connecting pipe 3 in the vertical direction A to a certain extent.

[0031] Optionally, refer to Figure 2 As shown, the baffle 52 includes a baffle surface 520 in the horizontal direction B for conforming to the housing 51. The baffle surface 520 is configured as an arcuate surface protruding toward the housing 51. By providing the arcuate surface, the housing 51 and the venting connection pipe 3 can swing relative to the arcuate surface.

[0032] This disclosure also provides a muffler, which includes a muffler body 1 and the aforementioned muffler connection device 5. The muffler body 1 includes a vent connection pipe 3 and a housing 100.

[0033] Optionally, refer to Figure 1 As shown, the housing 100 includes a housing body 101 and a base plate 10. The base plate 10 extends along the horizontal direction B and is connected to the interior of the housing body 101. An installation hole is formed on the base plate 10 for the venting connection pipe 3 to pass through. The swing sleeve of the muffler connection device 5 is fixedly connected to the base plate 10.
