Description

Technical Field

[0001] This utility model relates to the field of noise reduction and sound insulation technology, and in particular to a noise reduction cover for a dust removal pipe. Background Technology

[0002] Dust removal systems are used to exhaust dust-laden air, purifying it before discharge, and play a vital role in optimizing the factory environment. However, the airflow in dust removal ducts generates a significant amount of noise. Currently, to reduce the impact of this noise on the factory and external environments, sound-absorbing cotton is often wrapped around the ducts, and silencers are installed at the ends of the ducts. However, using sound-absorbing cotton has limited sound insulation effect, and as the service life extends, the cotton is prone to aging and shedding. Utility Model Content

[0003] This utility model provides a dust removal pipe noise reduction cover to overcome the shortcomings of the prior art and solve the problem of poor noise reduction effect of the existing methods, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A noise reduction cover for a dust removal pipe includes multiple noise reduction components fitted on a rectangular pipe. The noise reduction components are in the form of a rectangular ring structure, and adjacent noise reduction components are connected to each other.

[0006] The noise reduction component includes a pair of concave-shaped kits with internal cavities filled with liquid. A convex plate is formed on the outer wall of the vertical section of the kit, with an inclined surface on the outer wall to form a right-angled trapezoidal structure. The outer end of the convex plate is the smaller end. Side plates are provided on both sides of the convex plate on the same side. An inner pressure block is bolted to both ends of the side plates. The inner wall of the inner pressure block is formed with an inner pressure inclined wall, which is tightly attached to the inclined surface of the convex plate. A screw is threaded through the inner pressure block, and a tightening nut is threaded to the outer end of the screw. The inner end of the tightening nut acts on the outer wall of the inner pressure block. The inner end of the screw is welded to the kit.

[0007] Furthermore, the inner wall of the kit is equipped with rubber cushioning strips.

[0008] Furthermore, an extension tube is connected to the outer wall of the transverse section of the kit. An outer ring is threaded to the outer periphery of the extension tube. An outer disc is provided at the outer end of the outer ring. An inner post is formed on the inner wall of the outer disc. The inner post is inserted into the extension tube. A conical hole is formed on the inner periphery of the extension tube. The inner end of the conical hole is the smaller end. An inner hole is opened at the inner end of the conical hole. A conical column is formed on the inner end of the inner post. The outer periphery of the conical column is tightly attached to the inner wall of the conical hole. An inner extension column is formed on the inner end of the conical column. The inner extension column is inserted into the inner hole.

[0009] Furthermore, a circular groove is formed on the inner end of the inner hole, and the diameter of the circular groove is larger than the diameter of the inner hole.

[0010] Furthermore, a connecting strip is formed on one side of the horizontal segment of the kit, and a fixing strip is formed on the other side of the horizontal segment of the kit. The fixing strip is located above the connecting strip, and the fixing strip on the kit of the noise reduction component is fixed to the connecting strip on the kit of the adjacent noise reduction component by screws.

[0011] Furthermore, two pairs of side connecting plates are formed on one side of the vertical section of the kit, and a connecting protrusion is formed on the upper end of the side connecting plate. There is a gap between the inner wall of the connecting protrusion and the side wall of the vertical section of the kit.

[0012] An inner panel is formed on one side of the vertical section of the kit. The inner panel is located between a pair of side panels. A pair of lugs are formed on both sides of the upper end of the inner panel, and the lugs are inserted into the gap.

[0013] The advantages of the above technical solution are:

[0014] This invention provides a cavity kit that reduces the energy of noise propagation by filling it with liquids such as water or oil, which are not conducive to air transmission.

[0015] This invention facilitates the fixing of each pair of kits, and during fixing, the kits can be tightly attached to the outer wall of the rectangular pipe, thereby improving the noise reduction effect.

[0016] This invention also facilitates the connection and fixing of adjacent components, and provides strong stability after fixing. Attached Figure Description

[0023] Figure 6 A magnified view of point B is shown. Detailed Implementation

[0024] like Figures 1-6 As shown, a dust removal pipe noise reduction cover includes multiple noise reduction components 2 sleeved on a rectangular pipe 1. The noise reduction components 2 have a rectangular ring structure, and adjacent noise reduction components 2 are sleeved and connected to each other.

[0025] The noise reduction component 2 includes a pair of concave-shaped kits 21. The inner wall of the kit 21 is provided with a rubber buffer strip 20. The interior of the kit 21 has a cavity 200 filled with liquid. A protruding plate 24 is formed on the outer wall of the vertical section of the kit 21. The outer wall of the protruding plate 24 has a slope 25 so that the protruding plate 24 has a right-angled trapezoidal structure and the outer end of the protruding plate 24 is the smaller end. Side plates 26 are provided on both sides of the protruding plate 24 on the same side. An inner pressure block 28 is installed at both ends of the side plates 26 by bolts 27. The inner wall of the inner pressure block 28 is formed with an inner pressure inclined wall. The inner pressure inclined wall is tightly attached to the slope 25 of the protruding plate 24. A screw 201 is passed through the inner pressure block 28. The outer end of the screw 201 is connected to a tightening nut 29 by a thread. The inner end of the tightening nut 29 acts on the outer wall of the inner pressure block 28. The inner end of the screw 201 is welded to the kit 21.

[0026] The noise reduction principle provided in this embodiment is as follows: noise propagates outward through the rectangular pipe 1. When the noise passes through the component 21, most of the noise energy will be absorbed by the water or oil filling the cavity 200, thereby reducing the energy of the noise propagating outward. Furthermore, the noise propagation can be further reduced by the further absorption of the component 21 wall, thereby improving the noise reduction effect.

[0027] In this embodiment, when fixing each pair of components 21, the operator places the inner pressure block 28 on the screw 201 and then tightens the top nut 29 so that the top nut 29 acts on the inner pressure block 28, thereby causing the inner pressure inclined wall of the inner pressure block 28 to act on the inclined surface 25 of the convex plate 24, thereby causing the component 21 to move closer to the rectangular pipe 1, thus achieving the purpose of fixing the component 21. This method also facilitates the connection and fixing operation of the component 21.

[0028] In some embodiments, a dust removal pipe noise reduction cover further includes an extension pipe 33 connected to the outer wall of the transverse section of the kit 21 to facilitate liquid injection into the cavity 200. The outer periphery of the extension pipe 33 is connected to an outer ring 36 by threads. An outer disk 37 is provided at the outer end of the outer ring 36. An inner insertion post 360 is formed on the inner wall of the outer disk 37. The inner insertion post 360 is inserted into the extension pipe 33. A conical hole 34 is formed on the inner periphery of the extension pipe 33. The inner end of the conical hole 34 is the smaller end. An inner hole is opened at the inner end of the conical hole 34. A conical post 361 is formed on the inner end of the inner insertion post 360. The outer periphery of the conical post 361 is in close contact with the inner wall of the conical hole 34 to improve the sealing effect of the conical post on the conical hole and prevent liquid leakage. The inner end of the conical column 361 is formed with an inner extension column 362, which is inserted into the inner hole. The inner end of the inner hole is provided with a circular groove 35, the diameter of which is larger than the diameter of the inner hole. The circular groove can prevent the liquid from moving outward. The reason for setting two external extension tubes 33 is mainly to facilitate the discharge of air in the cavity 200 when liquid is injected.

[0029] In this embodiment, during liquid filling, the injection tube is inserted into one of the extended tubes 33, and then liquid is injected into the cavity 200. During the injection process, the other extended tube 33 will expel air. After the liquid filling is completed, the two outer rings 36 are connected to the extended tubes 33 again by threads, thus sealing the hole communicating with the extended tubes 33 through the components set inside.

[0030] In some embodiments, a connecting strip 31 is formed on one side of the horizontal segment of the kit 21, and a fixing strip 32 is formed on the other side of the horizontal segment of the kit 21. The fixing strip 32 is located above the connecting strip 31. The fixing strip 32 on the kit 21 of the noise reduction component 2 is fixed to the connecting strip 31 on the kit 21 located on the adjacent noise reduction component 2 by screws.

[0031] In this embodiment, when fixing two adjacent components 21, one component 21 can be first placed on the rectangular pipe 1, and then the other component 21 can be placed on it. Then, the connecting strip 31 and the fixing strip 32 are connected and fixed by screws, thus completing the connection and fixing of the two components 21.

[0032] In some embodiments, two pairs of side connecting plates 22 are formed on one side of the vertical section of the kit 21. A connecting protrusion 23 is formed at the upper end of the side connecting plate 22, and there is a gap between the inner wall of the connecting protrusion 23 and the side wall of the vertical section of the kit 21. An insert plate 3 is formed on one side of the vertical section of the kit 21. The insert plate 3 is located between the pair of side connecting plates 22. A pair of lugs 30 are formed on both sides of the upper end of the insert plate 3, and the lugs 30 are inserted into the gap.

[0033] In this embodiment, when the two kits 21 are connected and fixed, the inner plate 3 is embedded between the side connecting plates 22 and the lug 30 is inserted into the gap, which can improve the stability of the connection between the two adjacent kits 21.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
