Description

Technical Field

[0001] This utility model relates to the field of deodorization and noise reduction technology, specifically to a deodorization and noise reduction structure. Background Technology

[0002] Odor-reducing and noise-absorbing structures typically refer to specific designs or devices used to reduce or eliminate odors and noise. Such structures can be applied in various environments, such as buildings, industrial equipment, and automobiles, to improve the comfort and health of living or working environments. In many places, such as garbage disposal stations, sewage treatment plants, and public restrooms, unpleasant odors are generated. In some cases, the operation of industrial equipment and ventilation systems can generate significant noise. Therefore, an odor-reducing and noise-absorbing structure is needed.

[0003] Existing noise reduction equipment often has only one function and is not effective in dealing with noise in some special environments. It is also difficult to achieve both deodorization and noise reduction functions effectively through a single structure. Utility Model Content

[0004] The purpose of this invention is to provide a deodorizing and noise-absorbing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deodorizing and noise-absorbing structure, comprising an outer shell,

[0006] An air outlet pipe is fixedly installed on the right side wall of the outer shell;

[0007] And a processing assembly located on the side of the outer shell;

[0008] The processing assembly includes a processing mechanism located on the side of the outer shell;

[0009] An auxiliary mechanism is provided on the side of the outer shell.

[0010] Preferably, the processing mechanism includes a partition plate, which is fixedly installed on the inner wall of the outer shell. A porous tube is fixedly installed on the side wall of the partition plate. A sound-absorbing layer is disposed in contact with the side wall of the porous tube. A deodorizing layer is disposed in contact with the side wall of the sound-absorbing layer. A limit strip is disposed in contact with the side wall of the deodorizing layer. The side wall of the limit strip is slidably connected to the arc-shaped groove inside the outer shell.

[0011] Preferably, the sidewall of the sound-absorbing layer is slidably connected to the inner wall of the outer shell, and the sidewall of the deodorizing layer is slidably connected to the inner wall of the outer shell.

[0012] Preferably, the sidewall of the porous tube has a circular groove, and the sidewall of the partition has a rectangular groove.

[0013] Preferably, there are two deodorizing layers, both of which are equal in shape and size, and are symmetrically arranged with respect to the midpoint of the outer shell in the front-rear direction.

[0014] Preferably, the auxiliary mechanism includes a sealing plate, which is hinged to the side wall of the outer shell. An air inlet pipe is fixedly installed on the side wall of the sealing plate, and a positioning plate is fixedly installed on the side wall of the sealing plate. A positioning bolt is rotatably installed on the inner wall of the positioning plate, and an mounting plate is installed at one end of the positioning bolt.

[0015] Preferably, the inner wall of the mounting plate is threaded to one end of the positioning bolt, and the side wall of the mounting plate is fixedly connected to the front of the outer shell. By rotating, one end of the positioning bolt can be disengaged from the inner wall of the mounting plate.

[0016] This utility model provides a deodorizing and noise-absorbing structure. It has the following beneficial effects:

[0017] (1) In this utility model, the operator attaches the sound-absorbing layer to the side wall of the porous tube, then installs the deodorizing layer on both sides of the porous tube, and then slides the limiting strip to the inner wall of the outer shell. When the airflow with odor and noise enters the inner shell, it first passes through the porous tube, which is a metal plate with tiny holes. On the one hand, it can serve as a support structure, and on the other hand, it can further disperse the airflow and reduce noise generation. It also helps the deodorizing layer and the sound-absorbing layer to work evenly. Then it passes through the sound-absorbing layer, which is made of glass wool. The porous structure of the glass wool can effectively The sound absorbs and reflects sound waves, reducing noise transmission. Then, it passes through a deodorizing layer composed of activated carbon and nano-photocatalytic materials. Activated carbon has a strong adsorption capacity and can adsorb various odor molecules, while nano-photocatalytic materials can decompose organic odor molecules under light conditions, further improving the deodorizing effect. Finally, it flows out through rectangular grooves on the surface of the partition and is discharged through the air outlet duct. This solves the problems that existing silencers are often single-function and have poor noise treatment effect in some special environments, and it is difficult to achieve deodorization and noise reduction functions simultaneously and effectively through a single structure.

[0018] (2) When the operator needs to replace or repair the sound-absorbing layer, deodorizing layer and limiting strip, the positioning bolt can be rotated directly. One end of the positioning bolt will be disengaged from the inside of the mounting plate, and then the sealing plate can be rotated directly. The sealing plate can be rotated through the hinge, which makes it convenient for the operator to clean and repair the internal structural parts and to use the device better.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] Example 1: A preferred embodiment of the deodorizing and noise-absorbing structure provided by this utility model Figures 1 to 4 As shown: A deodorizing and noise-absorbing structure, including an outer shell 1,

[0026] The air outlet duct 2 is fixedly installed on the right side wall of the outer shell 1;

[0027] And the processing component 4 located on the side of the outer shell 1;

[0028] The processing component 4 includes a processing mechanism 41 located on the side of the outer shell 1;

[0029] An auxiliary mechanism 42 is provided on the side of the outer shell 1.

[0030] The processing mechanism 41 includes a partition 412, which is fixedly installed on the inner wall of the outer shell 1. A porous tube 413 is fixedly installed on the side wall of the partition 412. A sound-absorbing layer 414 is provided in contact with the side wall of the porous tube 413. A deodorizing layer 415 is provided in contact with the side wall of the sound-absorbing layer 414. A limit strip 411 is provided in contact with the side wall of the deodorizing layer 415. The side wall of the limit strip 411 is slidably connected to the arc-shaped groove inside the outer shell 1.

[0031] In this embodiment, the sidewall of the sound-absorbing layer 414 is slidably connected to the inner wall of the outer shell 1, and the sidewall of the deodorizing layer 415 is slidably connected to the inner wall of the outer shell 1.

[0032] Furthermore, a rectangular groove is formed between the side wall of the partition 412 and the right side wall of the outer shell 1, and a deodorizing filter element (not shown) can also be installed in the rectangular groove to further deodorize and filter the air.

[0033] Furthermore, there are two deodorizing layers 415, both of which are equal in shape and size, and are symmetrically arranged with respect to the midpoint of the outer shell 1 in the front-rear direction.

[0034] In practical implementation, when the operator uses the device, firstly, the sound-absorbing layer 414 is fitted onto the side wall of the porous tube 413, then the deodorizing layer 415 is installed on both sides of the porous tube 413. Next, the limiting strip 411 is slidably installed onto the inner wall of the outer shell 1. When airflow containing odors and noise enters the outer shell 1, it first passes through the porous tube 413. The porous tube 413 is a metal plate with tiny pores; it serves as a support structure and further disperses the airflow, reducing noise generation and aiding in deodorization. The sound-absorbing layer and the sound-absorbing layer work evenly, and then the sound-absorbing layer 414, which is made of glass wool, has a porous structure that can effectively absorb and reflect sound waves and reduce noise transmission. Then it passes through the deodorizing layer 415, which is a mixture of activated carbon and nano-photocatalyst material. Activated carbon has a strong adsorption capacity and can adsorb a variety of odor molecules. Nano-photocatalyst material can decompose organic odor molecules under light conditions, further improving the deodorizing effect. Finally, it flows out through the rectangular groove on the surface of the partition 412 and is discharged through the air outlet duct 2.

[0035] Understandably, the porous pipe 413 is sealed at one end near the partition 412, and the other end is the air inlet. The partition 412 and the deodorizing layer 415 are provided with several through holes, so that the dirty air coming in from the air inlet can only flow out from the side wall of the porous pipe 413, and pass through the sound-absorbing layer 414 and the deodorizing layer 415 in sequence, and flow from the through holes on the partition 412 to the rectangular groove.

[0036] Example 2: Based on Example 1, a preferred embodiment of the deodorizing and noise-absorbing structure provided by this utility model is as follows: Figures 1 to 4 As shown: The auxiliary mechanism 42 includes a sealing plate 422, which is hinged to the side wall of the outer shell 1. An air inlet pipe 421 is fixedly installed on the side wall of the sealing plate 422. The air inlet pipe 421 is inserted into the air inlet. A positioning plate 425 is fixedly installed on the side wall of the sealing plate 422. A positioning bolt 424 is rotatably installed on the inner wall of the positioning plate 425. An installation plate 423 is installed on one end of the positioning bolt 424.

[0037] In this embodiment, the inner wall of the mounting plate 423 is threadedly connected to one end of the positioning bolt 424, and the side wall of the mounting plate 423 is fixedly connected to the front of the outer shell 1. By rotating, one end of the positioning bolt 424 can be disengaged from the inner wall of the mounting plate 423.

[0038] In the specific implementation process, when the operator needs to replace or repair the sound-absorbing layer 414, the deodorizing layer 415 and the limiting strip 411, he can directly rotate the position of the positioning bolt 424. One end of the positioning bolt 424 will be disengaged from the interior of the mounting plate 423, and then the position of the sealing plate 422 can be directly rotated. The sealing plate 422 can be rotated through the hinge, which makes it convenient for the operator to clean and repair the internal structural parts.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
