Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction, in particular to an externally packaged noise reduction module. Background Art

[0002] Pipeline silencing is an important project in the construction of pipe corridors. The current method of pipe silencing is to wrap a layer of silencing pad on the outside of the pipe, and fix the silencing pad by means of cable ties or adhesive tapes after wrapping. However, when using the adhesive tape to fix, the adhesive tape is prone to aging over time, thereby affecting the fixing effect of the silencing pad. When using cable ties to fix, it is easy for some parts of the silencing pad to deform, and over time, the silencing pad is often disconnected at the binding position, thereby affecting the silencing effect. At the same time, the existing silencing pad is a single-layer structure, which is a single-layer cotton material. This material is prone to aging over time, thereby affecting its noise reduction effect. Utility Model Content

[0003] The utility model provides an externally packaged silencer module to solve the deficiencies of the above-mentioned prior art, improve the noise reduction effect on the pipeline, and improve the fixing effect, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] An externally wrapped silencer module includes a bonding layer wrapped around the outer layer of a pipe, a buffer layer is arranged on the outer side of the bonding layer, and an aluminum foil is arranged on the outer side of the buffer layer. The bonding layer is made of rubber, which is mainly used to improve the bonding effect between the silencer module and the pipe. The buffer layer mainly serves the purpose of noise reduction. The setting of the aluminum foil can reflect part of the sunlight to slow down the aging of the buffer layer, and can also effectively protect the buffer layer.

[0006] The outer side of the aluminum foil is provided with a plurality of fastening mechanisms. The fastening mechanism includes a pair of arc plates sleeved on the outer periphery of the aluminum foil, and convex parts are provided at both ends of the arc plates, and a pull plate is provided on each pair of convex parts at the same end, and the pull plate is provided on one of the convex parts, and the pull plate is passed through the other convex part, and an outer pull plate is provided at the outer end of the pull plate, and a screw rod is screwed on the outer pull plate, and a rotating cap is provided at the outer end of the screw rod, and a rotating table is provided at the inner end of the screw rod, and the rotating table is provided on the arc plate. Fixing the silencer component by a pair of arc plates with a larger width is convenient for operation. During operation, the arc plate is sleeved on the pipe, and then the silencer component is tied and fixed through the arc plate by rotating the screw rod.

[0007] Furthermore, the laminating layer is made of a flexible material, and the flexible material usually selected is a material that is easily deformable, such as rubber.

[0008] Furthermore, a plurality of spiral pads are provided on the inner side of the bonding layer. This arrangement is intended to improve the supporting effect of the bonding layer. In this way, the noise can first pass through the pipe wall, then propagate in the spiral pads, and then be weakened by the bonding layer, and then be weakened again by the buffer layer. The noise is weakened through a variety of different transmission media, thereby improving the noise reduction effect.

[0009] Furthermore, the buffer layer is made of porous foam material to improve the noise reduction effect.

[0010] Furthermore, the pull plate is a concave structure, and the inner wall of the pull plate is provided with a plurality of right-angled trapezoidal blocks, and a pair of convex parts are provided with through holes, through which the pull plate is passed, and the through holes are provided with right-angled trapezoidal clamps, which are clamped between two adjacent right-angled trapezoidal blocks. This structural design makes it convenient for operators to put the arc plate on the pipeline.

[0011] The advantages of the above technical solution are:

[0012] The utility model improves the noise reduction effect on the pipeline, is convenient for fixing the silencer component, and has strong stability after being fixed. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1~Figure 2As shown, an externally wrapped silencer module includes a bonding layer 2 wound around the outer layer of a pipe 1, the bonding layer 2 is made of a flexible material, and a plurality of spiral pads 20 are arranged on the inner side of the bonding layer 2. A buffer layer 21 is arranged on the outer side of the bonding layer 2, and the buffer layer 21 is made of a porous foam material. An aluminum foil 22 is arranged on the outer side of the buffer layer 21. A plurality of fastening mechanisms are arranged on the outer side of the aluminum foil 22. The fastening mechanism includes a pair of arc plates 3 sleeved on the outer periphery of the aluminum foil 22, and convex portions 30 are arranged at both ends of the arc plates 3. A pull plate 31 is arranged on each pair of convex portions 30 at the same end, and the pull plate 31 is arranged on one of the convex portions 30, and the pull plate 31 is arranged on the other convex portion 30. An outer pull plate 32 is arranged on the outer end of the pull plate 31, and a screw rod 33 is screwed on the outer pull plate 32. A rotating cap 34 is arranged on the outer end of the screw rod 33, and a rotating table 35 is arranged on the inner end of the screw rod 33. The rotating table 35 is arranged on the arc plate 3. The pull plate 31 has a concave structure, and a plurality of right-angled trapezoidal blocks 36 are provided on the inner wall of the pull plate 31 . A pair of protrusions 30 are provided with through holes, and the pull plate 31 passes through the through holes. A right-angled trapezoidal clamp 38 is provided on the through holes, and the right-angled trapezoidal clamp 38 is clamped between two adjacent right-angled trapezoidal blocks 36 .

[0017] When installing the present embodiment, the bonding layer 2, the buffer layer 21 and the aluminum foil 22 are first wrapped on the outside of the pipe 1, and the spiral pad 20 needs to be tightly attached to the outer wall of the pipe 1 when wrapping. When the noise propagates outward, the noise first passes through the pipe wall, and then propagates in the air to the bonding layer 2, and the noise is weakened by the bonding layer 2. Then part of the noise continues to propagate and passes through the buffer layer 21, and the energy of the noise is further weakened by the buffer layer 21. Finally, a small part of the noise will propagate outward. When fixing the silencer component, first put the two arc plates 3 on the pipe 1, then pass the pull plate 31 through the perforation, and make the right-angle trapezoidal clamp 38 clamped between two adjacent right-angle trapezoidal blocks 36, and then the operator rotates the screw 33 to fix the silencer component with the two arc plates 3.

Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
