Description

Technical Field

[0001] This utility model relates to a device for reducing environmental noise in a dryer, belonging to the technical field of noise reduction devices. Background Technology

[0002] The silencer of a dryer is usually installed at the exhaust port of the induced draft fan. It helps to reduce the noise generated during the operation of the dryer and improve the comfort of the working environment. Its working principle is that the gas is expanded and depressurized inside the silencer before being ejected, and then further silenced by the sound-absorbing cover before being discharged into the atmosphere, thereby reducing noise.

[0003] The equipment is currently located indoors. Due to the enclosed nature of the room, sound diffusion is poor, resulting in ineffective noise reduction. Furthermore, the noise level is high during purging, severely impacting the hearing of operators. Additionally, the large amount of gas expelled from the silencer during each purging cycle can easily cause injury to inspecting personnel. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a device for reducing the environmental noise of a dryer, so as to solve the above-mentioned problems.

[0005] The device for reducing ambient noise of a dryer according to this utility model includes a dryer and a silencer. The dryer is located indoors, and the silencer is located outdoors. The silencer is connected to the exhaust port of the dryer through a steel pipe that passes through the wall. The steel pipe is a tapered pipe, with the end connected to the silencer having a larger diameter and the end connected to the dryer having a smaller diameter.

[0006] This invention utilizes a steel pipe to install the silencer outdoors, which not only reduces indoor noise but also ensures the safety of inspection personnel. The steel pipe connecting the dryer and the silencer is tapered, allowing gas to expand initially during conduction, thus enhancing the overall noise reduction effect.

[0007] Preferably, the steel pipe is wrapped with sound-absorbing cotton to further improve the sound absorption effect.

[0008] The wall of this utility model has an opening and a sleeve installed. The sleeve is fixed inside the opening of the wall and is also a tapered tube.

[0009] Specifically, the sleeve has a flange at the larger diameter end, which is connected to a bolt that penetrates the wall. The sleeve is then fixed to the wall by the bolt. The steel pipe is detachable, and the sound-absorbing cotton can be removed and replaced if damaged or ineffective.

[0010] In addition, the silencer can be detached and fixed to the ground.

[0011] The advantages of this utility model compared with the prior art are:

[0012] The device for reducing ambient noise in a dryer, as described in this invention, significantly reduces indoor noise levels and improves the comfort of the working environment by installing the silencer outdoors, thus avoiding the limitations of a confined indoor environment on sound diffusion. This not only reduces noise but also ensures the safety of inspection personnel, preventing injury to operators. Furthermore, the steel pipe connecting the dryer and the silencer is designed in a conical shape, allowing the gas to initially expand during conduction, enhancing the overall noise reduction effect of the device.

[0015] The present invention will be further described below with reference to specific embodiments.

[0016] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0017] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0018] like Figure 1 As shown, this embodiment is achieved through the following technical solution: it includes a dryer 1 and a silencer 2. The dryer 1 is located indoors, the silencer 2 is located outdoors, the steel pipe 3 passes through the wall 6, and the silencer 2 is connected to the exhaust port of the dryer 1 through the steel pipe 3.

[0019] In this embodiment, the steel pipe 3 is a tapered pipe. The end connected to the silencer 2 has a larger diameter, while the end connected to the dryer 1 has a smaller diameter. This allows the gas to undergo preliminary expansion through the tapered steel pipe during conduction, enhancing the overall noise reduction effect of the device. In addition, the steel pipe 3 is also wrapped with sound-absorbing cotton.

[0020] In this embodiment, the wall 6 has an opening and a sleeve 4 is installed. The sleeve 4 is fixed inside the opening of the wall 6 and is also a tapered tube. The larger diameter end of the sleeve 4 is provided with a flange, which is connected to a bolt 5 that penetrates the wall 6. The sleeve 4 is fixed inside the wall 6 by the bolt 5. The silencer 2 is detachably fixed to the ground. The steel pipe 3 is detachable. The sound-absorbing cotton can be removed and replaced after it is damaged or fails.

[0021] This invention, by installing the silencer outdoors, avoids the limitation of sound diffusion in a closed indoor environment, thereby significantly reducing indoor noise levels and improving the comfort of the working environment. It not only reduces noise but also ensures the safety of inspection personnel, preventing injury to the operation personnel during inspections.

[0022] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
