Description

A noise reduction and sound-absorbing vacuum pump Technical Field

[0001] This utility model belongs to the field of vacuum pump technology, specifically relating to a noise reduction and silencing vacuum pump. Background Technology

[0002] The existing vacuum pump is one of the pieces of equipment used in the tobacco power workshop for processing and production. When the vacuum pump is in use, it is protected by a noise reduction box, and the main sound-absorbing cotton is treated to absorb sound during noise reduction, thereby reducing the processing noise in the workshop and providing a better environment for processing and production.

[0003] When existing vacuum pumps are used in tobacco power workshops for processing and production, and the vacuum pump is protected by a noise reduction box, air is drawn into the noise reduction box through the air intake channel during operation. As a result, the end of the air intake channel is directly exposed to the outside environment, making it difficult to filter the air during intake. This allows a large amount of dust to easily enter the vacuum pump during intake, and the dust entering the vacuum pump over a long period of time can shorten its service life. This affects the convenience of filtering the air intake channel when the vacuum pump is used for noise reduction. Therefore, this utility model proposes a noise reduction and silencer vacuum pump. Summary of the Invention

[0004] The purpose of this invention is to provide a noise-reducing and sound-absorbing vacuum pump to solve the problem mentioned in the background art that the vacuum pump operates by taking in air into the noise-reducing box through the air intake channel. As a result, the end of the air intake channel is directly exposed to the outside environment, making it inconvenient to filter the air during intake. This makes it easy for a large amount of dust to enter the vacuum pump during intake, and the dust entering the vacuum pump for a long time can shorten its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing and sound-absorbing vacuum pump, comprising a noise-reducing and sound-absorbing vacuum pump body, the noise-reducing and sound-absorbing vacuum pump body comprising a base, a noise-reducing box fixedly installed at the edge of the base surface, a main sound-absorbing cotton fixedly installed on the inner surface of the noise-reducing box, an air inlet channel provided at the tail end of the noise-reducing box, perforated sound-absorbing cotton fixedly installed inside the air inlet channel, a vacuum pump body provided inside the noise-reducing box, an exhaust port and an air inlet provided on the upper surface of the end of the vacuum pump body, the end of the exhaust port extending to the top of the noise-reducing box;

[0009] Preferably, the filter assembly includes a fixing ring disposed on the surface of the air intake channel, and a filter plate two and a filter plate one are disposed on both sides inside the fixing ring.

[0010] Preferably, the elastic locking assembly includes a limiting groove formed at the end edge of the air intake channel, a locking head is provided inside the limiting groove, an elastic block is provided at the connection between the surface of the locking head and the inside of the limiting groove, and a locking hole is formed at the edge of the fixing ring.

[0011] Preferably, the end of the clip engages with the interior of the second clip hole, and a threaded lever slides on the surface of the air intake channel, the end of which is rotatably connected to the interior of the clip via a thread.

[0012] Preferably, the fixed mounting assembly includes a built-in fixed base plate disposed on the upper surface of the base, and two support feet are threadedly rotatably connected to the lower surface of one end of the built-in fixed base plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By designing a filtration mechanism, filter plate two and filter plate one can be fixed inside the air intake channel using a fixing ring.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 6. This utility model provides a technical solution: a noise-reducing and silencing vacuum pump, including a noise-reducing and silencing vacuum pump body 100. The noise-reducing and silencing vacuum pump body 100 includes a base 102, on which a noise-reducing box 101 is fixedly installed. A vacuum pump body 106 is disposed inside the noise-reducing box 101. An exhaust port 104 and an air inlet 107 are provided on the upper surface of the end of the vacuum pump body 106. The end of the exhaust port 104 extends to the top of the noise-reducing box 101. When the noise-reducing and silencing vacuum pump body 100 is installed and used in a tobacco power workshop, when the vacuum pump body 106 is running, air is introduced into the noise-reducing box 101 through the air inlet 107 and then discharged to the outside through the exhaust port 104. To enable the noise-reducing vacuum pump body 100 to perform noise reduction and silencing operations in the tobacco power workshop, a main sound-absorbing cotton 105 is fixedly installed on the inner surface of the noise reduction box 101. An air inlet channel 103 is provided at the tail end of the noise reduction box 101, and perforated sound-absorbing cotton 108 is fixedly installed inside the air inlet channel 103, providing noise reduction protection through the noise reduction box 101 during use. Simultaneously, the main sound-absorbing cotton 105 absorbs sound, reducing workshop processing noise and providing a better processing and production environment. The noise-reducing vacuum pump body 100 is also equipped with:

[0026] The filter mechanism includes a filter assembly disposed inside the air intake channel 103. An elastic engaging component is provided at the edge of the filter assembly to engage the filter mechanism with the inner wall of the air intake channel 103. When the noise-reducing and sound-absorbing vacuum pump body 100 is in use, air is introduced through the air intake channel 103. The filter mechanism filters the gas within the air intake channel 103, preventing dust from easily entering the interior of the vacuum pump body 106 during air intake, thus facilitating cleaning of the air intake operation.

[0027] To enable the filter assembly to filter internal dirt and dust during air intake, in this embodiment, preferably, the filter assembly includes a fixing ring 1031 disposed on the inner surface of the air intake channel 103. A second filter plate 1032 and a first filter plate 1033 are disposed on both sides of the inner side of the fixing ring 1031. After the fixing ring 1031 is closed inside the air intake channel 103, it can fix the second filter plate 1032 and the first filter plate 1033. The second filter plate 1032 and the first filter plate 1033 cover the cross-section of the air intake channel 103. Thus, the gas inside the air intake channel 103 is filtered through the second filter plate 1032 and the first filter plate 1033. Therefore, dust is less likely to enter the vacuum pump body 106, and the air intake can be kept clean.

[0028] The retaining ring 1031 is easily closed and fixed after installation using the elastic locking assembly. In this embodiment, preferably as shown in Figure 5, the elastic locking assembly includes a limiting groove 1034 formed at the end edge of the air intake channel 103. A locking head 1035 is provided inside the limiting groove 1034, and an elastic block 1036 is provided at the connection between the surface of the locking head 1035 and the inside of the limiting groove 1034. The locking head 1035 is elastically connected inside the limiting groove 1034 by the elastic block 1036, which facilitates elastic locking installation. A second locking hole 1037 is formed at the edge of the retaining ring 1031, until the locking head 1035 is elastically locked inside the second locking hole 1037 and tightly pressed and fixed. A threaded lever 1038 slides on the outer surface of the air intake channel 103. The end of the threaded lever 1038 is connected to the inside of the clamp 1035 by a threaded rotation. Rotating the threaded lever 1038 again reinforces the clamp 1035. It is also convenient to loosen the threaded lever 1038 to adjust the clamp 1035 during disassembly and assembly.

[0029] The system includes a convenient adjustment mechanism, comprising a fixed mounting assembly positioned at the center of the upper surface of the base 102. Sliding adjustment components are located on both sides of the lower surface of the fixed mounting assembly. Reinforcing components are provided at the connection points between the ends of the fixed mounting assembly and the noise reduction housing 101. This allows the vacuum pump body 106 to be easily opened for maintenance on the surface of the base 102 via the convenient adjustment mechanism, or to be slidably closed inside the noise reduction housing 101 for installation and use, facilitating disassembly and maintenance.

[0030] The fixed mounting assembly facilitates the fixed installation of the vacuum pump body 106 and also facilitates disassembly and assembly. In this embodiment, preferably, the fixed mounting assembly includes a built-in fixed base plate 1021 disposed on the upper surface of the base 102. Two support feet 1022 are threadedly rotatably connected to the lower surface of one end of the built-in fixed base plate 1021. During installation, the built-in fixed base plate 1021 can be slid open to allow the vacuum pump body 106 to be accessed for external maintenance, and it is supported and placed by the support feet 1022.

[0031] To facilitate the sliding adjustment assembly for easy access and maintenance of the built-in fixed base plate 1021 and the vacuum pump body 106, or for easy installation and disassembly, the sliding adjustment assembly preferably includes slots 1024 formed on both sides of the lower surface of the built-in fixed base plate 1021, and a retaining plate 1023 integrally provided on both sides of the upper surface of the base 102. The internal structures of the retaining plate 1023 and the slots 1024 are matched, allowing for convenient disassembly and assembly of the built-in fixed base plate 1021 and the vacuum pump body 106 by sliding the retaining plate 1023 within the slots 1024, and facilitating external access during maintenance.

[0032] To facilitate the installation and secure closure of the built-in fixed base plate 1021 and the vacuum pump body 106 onto the surface of the base 102 using a reinforcing component, in this embodiment, preferably, the reinforcing component includes two limiting movement grooves 1026 formed at the end of the built-in fixed base plate 1021. An extrusion block 1027 is positioned inside each limiting movement groove 1026. A threaded rod 1025 is threaded onto the upper surface of the built-in fixed base plate 1021. The end of the threaded rod 1025 is connected to the top of the extrusion block 1027 via a bearing, allowing the end of the threaded rod 1025 to rotate in place within the extrusion block 1027 when rotated, thus moving and adjusting the extrusion block 1027. Two locking holes 1028 are formed at one end of the upper surface of the base 102. The extrusion block 1027 engages with the interior of the locking holes 1028 until the end of the extrusion block 1027 is moved and locked inside the locking holes 1028, thus pressing and fixing it.

[0033] The working principle and usage process of this utility model are as follows: Before use, this noise-reducing and silencing vacuum pump is first installed. The built-in fixed base plate 1021 is opened outside the noise-reducing box 101, and the rotating support feet 1022 are opened to contact the ground for support. The vacuum pump body 106 is then fixedly installed on the surface of the built-in fixed base plate 1021. After installation, the support feet 1022 are reset. The built-in fixed base plate 1021 is closed onto the base 102 and placed inside the noise-reducing box 101 by sliding the base 102 inside the slot 1024. The rotating threaded rod 1025 rotates through the bearing to move the pressing block 1027 downwards until the pressing block 1027 is pressed into the slot 1028, locking and fixing the built-in fixed base plate 1021. Conversely, if the vacuum pump body 106 is damaged and requires maintenance after prolonged use following installation of the noise-reducing and silence-absorbing vacuum pump body 100, the opposite operation is performed: the built-in fixing base plate 1021 and the vacuum pump body 106 are slid together, opening them from the outside of the noise-reducing box 101 for disassembly and maintenance, which is convenient. Compared to the case where the vacuum pump body 106 is directly fixed to the inner surface of the base plate 1021, the solution of this application simplifies maintenance operations and improves the convenience of disassembly and maintenance of the noise-reducing and silence-absorbing vacuum pump body 100 when it is damaged during processing and production in the tobacco power workshop.

[0034] Before using the noise-reducing and silence-absorbing vacuum pump body 100, the threaded lever 1038 is used to adjust the locking head 1035 into the limiting groove 1034. The retaining ring 1031 then closes the filter plate 1032 and filter plate 1033 onto the inner surface of the air intake channel 103. Releasing the threaded lever 1038 causes the elastic block 1036 to deform, pressing the locking head 1035 tightly into the locking hole 1037, thus locking the retaining ring 1031 in place. Therefore, when air enters the noise-reducing box 101 through the air intake channel 103, the gas passes through the filter plate 1032 and filter plate 1033 to filter dust before entering the interior. This design facilitates cleaning the air intake, prevents dust from entering the vacuum pump body 106, extends the service life of the vacuum pump body 106, and improves the convenience of filtration during air intake through the air intake channel 103 in tobacco power plant processing.
