Description

Technical Field

[0001] This utility model belongs to the field of noise reduction technology, and specifically relates to a noise reduction device for textile dewatering production lines. Background Technology

[0002] Textile workshops or production lines generate a lot of noise when they are working, including the noise generated during the dewatering process in dewatering production lines. Noise reduction measures are generally taken. For pipelines, noise reduction technology usually involves installing silencers along the pipeline path. Silencers include bent pipe type, straight pipe type, etc., with the honeycomb type being the most common.

[0003] After searching, a high-frequency fan-specific silencer with the existing technology announcement number CN222479060U was found. It improved upon the shortcomings of the above-mentioned silencers by setting up a fixed shell, a vent plate, and an air delivery chamber, which solved the problems of insufficient noise reduction effect and poor stability of air passing through the high-frequency fan-specific silencer; however, it also has corresponding drawbacks.

[0004] For example, although the vents are eccentrically set on the vent plate and the vents on the two adjacent vent plates are staggered, the setting of a single large-diameter vent has a low effect on changing the air delivery path. The direction of the air delivery between the upper and lower adjacent vent plates is still relatively stable, orderly and concentrated. After the air flows out of the vent, it faces the obstruction of the vent plate directly, so the vibration generated on the vent plate is still relatively large.

[0005] In response to the aforementioned drawbacks, the applicant proposed an improvement scheme that can achieve a significant noise reduction effect. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a noise reduction device for textile dewatering production lines. The noise reduction plate is provided with several through holes to divert air, and then the air is diverted again through the staggered through holes in the upper and lower adjacent noise reduction plates. This effectively diverts the concentrated large volume of air and reduces vibration.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A noise reduction device for a textile dewatering production line includes a pipe with a first sealing plate and a second sealing plate at both ends to achieve a sealing effect; the pipe also has an inlet pipe and an outlet pipe; the inlet pipe and the outlet pipe are connected to the pipe wall; the pipe has a channel and several sets of noise reduction plates inside; the noise reduction plates are located between the inlet pipe and the outlet pipe, and the pipe is located above the noise reduction plates; a partition is provided on the inner wall of the pipe, and a gap is provided between the partition and the inner wall of the pipe for filling with noise reduction material; the partition has honeycomb-shaped vent holes; the noise reduction plates are hollow inside for filling with noise reduction material, and the noise reduction plates have several through holes, and the inner wall of the through holes has honeycomb-shaped vent holes for sound waves to enter; the noise reduction material is one of polyester fiber noise reduction cotton, sound insulation felt, and corrugated sound-absorbing sponge.

[0009] When the sound-absorbing plates are stacked, the through holes at the top and bottom positions are staggered to disrupt the sound waves and achieve the purpose of sound absorption.

[0010] The inlet pipe is eccentrically positioned to connect to the side wall of the pipeline.

[0011] The channel is configured in a T-shape, allowing the sound waves inside the pipe to propagate from a wide-area pipe into a narrow-area channel, and then back into the wide-area pipe. This alters the stable propagation state of the sound waves, causing them to be disturbed.

[0012] The channel inlet is located below the outlet pipe, and the channel outlet is located above the outlet pipe. This can change the transmission direction, transmission distance, and transmission state of the sound waves, thereby achieving the effect of further reducing and weakening the sound waves.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] This solution replaces a single large-diameter vent with several sets of through holes on the silencing plate, maximizing the diversion of airflow during circulation, reducing the impact force per unit area, and thus weakening the vibration effect, thereby achieving a certain degree of noise reduction. Furthermore, the silencing plate's internal hollow cavity is filled with silencing material, and the numerous sets of through holes increase the contact area between sound waves and the silencing material. Combined with the silencing material on the inner wall of the pipe, it can effectively achieve noise reduction. Moreover, the eccentric design of the inlet pipe can create swirling airflow, allowing the air and sound waves to achieve initial silencing by the silencing material on the inner wall of the pipe during the swirling and rising process.

[0015] At the same time, the way the channels are set can also change the propagation path and propagation state of sound waves in air circulation to a certain extent. This includes staggered through holes, which can cut and disturb sound waves to a certain extent, so that the sound waves can cancel each other out to a certain extent. Attached Figure Description

[0022] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-5 The technical solution of this utility model will be further described in detail below.

[0023] A noise reduction device for a textile dewatering production line includes a pipe 1, with a first sealing plate 11 and a second sealing plate 12 at both ends of the pipe 1 to achieve a sealing effect; the pipe 1 also has an inlet pipe 2 and an outlet pipe 3; the inlet pipe 2 and the outlet pipe 3 are connected to the pipe wall of the pipe 1; the pipe 1 has a channel 5 and several sets of noise reduction plates 4 inside; the noise reduction plates 4 are located between the inlet pipe 2 and the outlet pipe 3, and the pipe 1 is located above the noise reduction plates 4; a partition 13 is provided on the inner wall of the pipe 1, and a gap is provided between the partition 13 and the inner wall of the pipe 1 for filling with noise reduction material 6, and the partition 13 has honeycomb-shaped vent holes; the noise reduction plates 4 are hollow inside for filling with noise reduction material, and the noise reduction plates 4 have several through holes 41, and the inner wall of the through holes 41 has honeycomb-shaped vent holes for sound waves to enter; the noise reduction material 6 is one of polyester fiber noise reduction cotton, sound insulation felt, and corrugated sound-absorbing sponge.

[0024] When the sound-absorbing plates 4 are stacked, the through holes 41 at the upper and lower positions are staggered to achieve the effect of disturbing sound waves and thus achieving the purpose of sound absorption.

[0025] The inlet pipe 2 is eccentrically positioned on the side wall of the connecting pipe 1, so that the air and sound waves rise after rotating, and are silenced by the sound-absorbing material on the inner wall of the pipe during this process.

[0026] The channel 5 is configured as a T-shape, which allows the sound waves in the pipe 1 to propagate from the wide-area pipe 1 into the narrow-area channel 5, and then back into the wide-area pipe 1. This can change the stable propagation state of the sound waves and disturb them.

[0027] The inlet of the channel 5 is located below the outlet pipe 3, and the outlet of the channel 5 is located above the outlet pipe 3. This can change the transmission direction, transmission distance, and transmission state of the sound wave, thereby achieving the effect of further reducing and weakening the sound wave.

[0028] A noise reduction device for a textile dewatering production line operates as follows:

[0029] The gas enters the pipe 1 through the inlet pipe 2, and then passes through the silencer plate 4 to silence it. When passing through the through hole 41, the sound wave is cut off and disordered by the staggered through hole 41, which reduces noise. At the same time, the noise reduction effect is improved with the help of the silencer material. Then, the sound wave is changed again in the process of passing through the channel 5, so that the propagation state is disturbed and changed again, and the noise is reduced again. Then it is discharged through the outlet pipe.
