Description

Technical Field

[0001] The present application relates to the technical field of mixing station silencer equipment, and in particular to an insect-proof silencer device for an air inlet of a mixing station. Background Art

[0002] The mixing plant control room is a key part of the concrete mixing plant. It concentrates various control and monitoring equipment, allowing operators to monitor and manage various systems of the mixing plant in a centralized area.

[0003] The concrete mixing plant control room is equipped with necessary electronic control equipment, such as electronic control equipment, batching control equipment, air pumps, and related switching power supply equipment. These devices together constitute the concrete mixing plant control system. However, the large number of devices operating in the concrete mixing plant control room generates a large amount of heat. Therefore, the concrete mixing plant control room usually has air inlets to circulate the air in the concrete mixing plant control room through natural wind, so that the accumulated heat can be discharged.

[0004] Chinese patent publication number CN215212590U discloses a containerized control room for a concrete mixing plant, comprising a room support, a closed support layer provided around the periphery and top of the room support, an interior finishing layer of thermal insulation, flame-proofing, and sound-absorbing materials provided on the inner side of the support layer, an independent and enclosed air-conditioning installation room provided inside the room, an air-conditioning outdoor unit provided within the room, and an air inlet for the air-conditioning outdoor unit provided on the support layer at the location of the air-conditioning installation room.

[0005] In the above technology, although sound-absorbing materials are set inside the room, a large amount of noise will be generated at the air inlet of the air conditioner outdoor unit due to the operation of the air conditioner outdoor unit. This noise will seriously affect the work of outdoor personnel. At the same time, the noise pollution will also seriously affect the environment, which has shortcomings. Utility Model Content

[0006] In order to improve the problem of noise pollution at the air inlet of a mixing station, the present application provides an insect-proof and silencer device for the air inlet of a mixing station.

[0007] The present application provides an anti-insect and silencer device for the air inlet of a mixing station, which adopts the following technical solution:

[0008] An insect-proof and silencer device for the air inlet of a mixing station includes an air inlet pipe, which is arranged at the air inlet of the mixing station. A sound-absorbing component for absorbing noise is provided on the air inlet pipe. The sound-absorbing component includes a plurality of sound-absorbing boxes arranged in the air inlet pipe, and the plurality of sound-absorbing boxes are arranged along the radial direction of the axis of the air inlet pipe. An air inlet channel is formed between two adjacent sound-absorbing boxes. The interior of the sound-absorbing box is hollow and has a plurality of sound-absorbing holes opened thereon. A sound-absorbing member for absorbing noise is provided on the sound-absorbing box.

[0009] By adopting the above technical solution, air flows into the interior of the mixing station through the air inlet channel, and the noise in the mixing station will be transmitted to the air inlet pipe. The noise will be transmitted to the sound-absorbing box through the sound-absorbing holes. The noise is constantly reflected and refracted in the sound-absorbing box, and the noise transmitted to the sound-absorbing box is absorbed by the sound-absorbing parts, thereby reducing the size of the noise transmitted from the air inlet, and further reducing the impact of the noise on outdoor workers.

[0010] Optionally, the cross-section of the sound absorbing box is V-shaped, and the sound absorbing holes are opened on the concave side of the V-shape of the sound absorbing box.

[0011] By adopting the above technical solution, when the noise is transmitted to the air intake passage, since the sound-absorbing box is V-shaped, the air intake passage is also V-shaped. The noise will be continuously reflected and refracted in the V-shaped air intake passage, so that most of the noise is transmitted to the inside of the sound-absorbing box through the sound-absorbing holes, thereby reducing the effect of noise transmission.

[0012] Optionally, the sound absorbing member includes sound absorbing cotton arranged inside the sound absorbing box, and a sound-absorbing coating is sprayed on the outer surface of the sound absorbing box.

[0013] By adopting the above technical solution, when noise is transmitted to the sound-absorbing box, the sound-absorbing coating on the sound-absorbing box absorbs the noise in the form of heat. At the same time, the noise transmitted to the inside of the sound-absorbing box will be absorbed by the porous structure inside the sound-absorbing cotton, thereby achieving a sound-absorbing effect.

[0014] Optionally, a detachable insect-proof frame is provided on the air inlet pipe, a mounting slot for inserting the insect-proof frame is opened on the air inlet pipe, an insect-proof net is provided on the insect-proof frame, the insect-proof net is used to block the cross-section of the air inlet pipe, a fixing part is provided between the insect-proof frame and the air inlet pipe, and the fixing part is used to fix the insect-proof frame on the air inlet pipe.

[0015] By adopting the above technical solution, the possibility of outdoor mosquitoes flying into the room through the air inlet pipe is reduced, which is beneficial to improving the living environment of indoor people.

[0016] Optionally, the fixing member includes a fixing bolt bolted to the air inlet pipe, and a fixing plate is provided on the insect-proof frame. The fixing plate is used to block the installation slot, and the fixing plate is slidably mounted on the fixing bolt.

[0017] By adopting the above technical solution, the installer can fix the insect-proof frame on the air inlet pipe by tightening the fixing bolts, thereby making it easier for workers to clean mosquitoes and other dirt attached to the insect-proof net, and reducing the possibility of the mesh holes of the insect-proof net being blocked by mosquitoes.

[0018] Optionally, the air inlet duct is provided with a plurality of mutually parallel slide rails, the cross-section of the slide rails is concave, the length direction of the slide rails is perpendicular to the length direction of the installation slot, a slider is slidingly provided on the slide rails, and a cleaning plate is commonly provided on the plurality of sliders, the length direction of the cleaning plate is parallel to the length direction of the installation slot, and a plurality of bristles are provided on the side of the cleaning plate facing the insect-proof net, and the bristles are used to abut against the insect-proof net.

[0019] By adopting the above technical solution, after the worker pulls out the insect-proof rack, the worker pushes the cleaning plate close to the insect-proof net so that the bristles on the cleaning plate are tightly attached to the insect-proof net. Then the worker only needs to repeatedly insert and pull out the insect-proof rack to clean the insect-proof net, which helps to reduce the cleaning difficulty for the worker.

[0020] Optionally, a dirt collecting box is provided below the cleaning plate and on the air inlet pipe.

[0021] By adopting the above technical solution, it is convenient for workers to collect and centrally process the dirt cleaned from the insect-proof net, which reduces the workload of workers who need to clean up the dirt again when it falls on the ground.

[0022] Optionally, a protective box is rotatably provided on the air inlet pipe, and the protective box is used to cover the cleaning plate.

[0023] By adopting the above technical solution, the protective box reduces the degree of aging of the bristles on the cleaning plate due to direct sunlight, which is beneficial to increasing the service life of the bristles on the cleaning plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Air flows into the concrete mixing station through the air inlet channel. The noise inside the concrete mixing station will be transmitted to the air inlet pipe. The noise will be transmitted to the sound-absorbing box through the sound-absorbing holes. The noise will be continuously reflected and refracted in the sound-absorbing box. The noise transmitted to the sound-absorbing box will be absorbed by the sound-absorbing parts, thereby reducing the noise level transmitted from the air inlet and reducing the impact of the noise on outdoor workers.

[0026] 2. When the noise propagates to the air intake passage, the V-shaped sound-absorbing box makes the air intake passage also V-shaped. The noise will be continuously reflected and refracted in the V-shaped air intake passage, so that most of the noise is transmitted to the inside of the sound-absorbing box through the sound-absorbing holes, thereby reducing the effect of noise transmission;

[0027] 3. After the worker pulls out the insect-proof rack, the worker pushes the cleaning plate close to the insect-proof net so that the bristles on the cleaning plate are close to the insect-proof net. Then the worker only needs to repeatedly insert and pull out the insect-proof rack to clean the insect-proof net, which helps to reduce the cleaning difficulty of the worker.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses an insect-proof and silencer device for an air inlet of a mixing station.

[0035] Example 1

[0036] Reference Figure 1 An insect-proof and silencer device for the air inlet of a mixing station includes an air inlet pipe 1, which is bolted to the air inlet of the mixing station. A sound-absorbing component 2 for absorbing noise is arranged on the air inlet pipe 1. The sound-absorbing component 2 includes a plurality of sound-absorbing boxes 21 bolted to the air inlet pipe 1. The plurality of sound-absorbing boxes 21 are evenly arranged in the radial direction of the axis of the air inlet pipe 1.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 An air intake channel 22 is formed between two adjacent sound-absorbing boxes 21. The interior of the sound-absorbing box 21 is hollow and has a V-shaped cross-section. A number of sound-absorbing holes 23 are opened on the concave side of the V-shaped sound-absorbing box 21. A sound-absorbing member 24 for absorbing noise is arranged on the sound-absorbing box 21. The sound-absorbing member 24 includes sound-absorbing cotton 241 filled in the interior of the sound-absorbing box 21, and a sound-absorbing coating 242 is sprayed on the outer surface of the sound-absorbing box 21.

[0038] Outdoor air flows into the interior of the mixing station through the air intake channel 22. The indoor noise will be transmitted to the sound-absorbing box 21. Part of the noise will be absorbed by the sound-absorbing coating 242 on the sound-absorbing box 21 by generating heat, and part of the noise will be transmitted to the V-shaped air intake channel 22, where the noise is constantly reflected and refracted.

[0039] During this process, the noise is continuously absorbed by the sound-absorbing coating 242 on the sound-absorbing box 21, and part of the noise is transmitted to the sound-absorbing box 21 through the sound-absorbing holes 23 during the process of reflection and refraction. The sound-absorbing cotton 241 in the sound-absorbing box 21 continuously reflects, refracts and absorbs the noise through its internal porous structure, thereby reducing the noise level transmitted from the air inlet pipe 1.

[0040] Reference Figure 1 、 Figure 2 and Figure 3 An insect-proof frame 3 is plugged into the air inlet pipe 1, and an installation slot 4 for inserting the insect-proof frame 3 is opened on the air inlet pipe 1. An insect-proof net 5 is bonded to the insect-proof frame 3, and the insect-proof net 5 is used to block the cross-section of the air inlet pipe 1. A fixing part 6 is arranged between the insect-proof frame 3 and the air inlet pipe 1.

[0041] Reference Figure 1 、 Figure 2 and Figure 3 The fixing member 6 is used to fix the insect-proof frame 3 on the air inlet pipe 1. The fixing member 6 includes a fixing bolt 61 bolted to the air inlet pipe 1. A fixing plate 62 is welded on the insect-proof frame 3. The fixing plate 62 is used to block the installation slot 4. The fixing plate 62 is slidably mounted on the fixing bolt 61.

[0042] The worker inserts the anti-insect frame 3 into the air inlet pipe 1 through the installation slot 4, and then tightens the fixing bolts 61 to fix the fixing plate 62 on the air inlet pipe 1, thereby reducing the possibility of outdoor mosquitoes flying into the room through the air inlet pipe 1.

[0043] The implementation principle of Example 1 is as follows: outdoor air flows into the interior of the mixing station through the air intake channel 22, and the indoor noise will be transmitted to the sound-absorbing box 21. Part of the noise will be absorbed by the sound-absorbing coating 242 on the sound-absorbing box 21 by generating heat, and part of the noise will be transmitted to the V-shaped air intake channel 22, where the noise is continuously reflected and refracted.

[0044] During this process, the noise is continuously absorbed by the sound-absorbing coating 242 on the sound-absorbing box 21, and part of the noise is transmitted to the sound-absorbing box 21 through the sound-absorbing holes 23 during the process of reflection and refraction. The sound-absorbing cotton 241 in the sound-absorbing box 21 continuously reflects, refracts and absorbs the noise through its internal porous structure, thereby reducing the noise level transmitted from the air inlet pipe 1.

[0045] Example 2

[0046] refer to Figure 4 The difference between this embodiment and embodiment 1 is that: a plurality of mutually parallel slide rails 7 are welded on the outer wall of the air inlet duct 1, the cross section of the slide rail 7 is concave, the length direction of the slide rail 7 is perpendicular to the length direction of the installation slot 4, a slider 8 is slidably arranged on the slide rail 7, and a cleaning plate 9 is welded to the plurality of sliders 8, and the length direction of the cleaning plate 9 is parallel to the length direction of the installation slot 4.

[0047] refer to Figure 4 A number of bristles 10 are bonded to the side of the cleaning plate 9 facing the insect-proof net 5. The bristles 10 are used to abut against the insect-proof net 5. A dirt collecting box 11 is bolted to the air inlet pipe 1 below the cleaning plate 9. A protective box 12 is hinged on the air inlet pipe 1. The protective box 12 is used to cover the cleaning plate 9.

[0048] The implementation principle of Example 2 is as follows: when a worker needs to clean the insect-proof net 5, the worker turns to open the protective box 12, then loosens the fixing bolt 61, and then pulls out the insect-proof frame 3, and at the same time pushes the cleaning plate 9 close to the insect-proof net 5 until the bristles 10 on the cleaning plate 9 are pressed against the insect-proof net 5, and then the worker repeatedly inserts and pulls out the insect-proof frame 3, and mosquitoes and other dirt attached to the insect-proof net 5 will fall into the dirt collecting box 11, and the worker only needs to clean the dirt collecting box 11 regularly.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
