Abstract
Description
Technical Field
[0001] This utility model relates to the field of silencers, and in particular to a silencer device for a material pump. Background Technology
[0002] Material pumps are used for packaging in the workshop. These pumps are quite noisy. The noise level in the area was measured to be 83.5 dB when measured by a noise meter. According to the "Industrial Enterprise Noise Hygiene Standard", the noise level in the production workshop and workplace of an industrial enterprise shall not exceed 85 dB. The noise level is already close to the critical point. Some positions require the wearing of earplugs, which causes inconvenience in communication between personnel and poses safety and quality risks. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a silencer device for a material pump, which has a good noise reduction effect and improves the working environment.
[0004] This utility model is implemented using the following solution: a silencer device for a material pump, including a silencer cylinder, an air inlet on one side of the bottom of the silencer cylinder, an air outlet at the bottom of the silencer cylinder, and several partitions inside the silencer cylinder that divide the internal space of the silencer cylinder into multiple chambers in the height direction. Several through holes are provided on one side of the partition, and the through holes of two adjacent partitions are staggered.
[0005] Furthermore, each cavity is filled with sponge.
[0006] Furthermore, the silencer body is cylindrical, with an outer diameter of 180mm and a height of 500mm.
[0007] Furthermore, a drain outlet is provided at the bottom of the silencer body.
[0008] Furthermore, a support foot is fixedly connected to the bottom of the silencer body.
[0009] Furthermore, the locations of the through holes in the upper and lower adjacent partitions are staggered on opposite sides.
[0010] Furthermore, the silencer body is made of stainless steel with a wall thickness of 3mm.
[0011] Furthermore, the diameter of the air inlet is 16mm, and the diameter of the air outlet is 10mm.
[0012] Furthermore, the bottom of the silencer body is concave spherical, and a valve is provided at the drain outlet.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The silencer device for the material pump of the present invention has a novel structure and reasonable design.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0021] like Figures 1-2As shown, a silencer device for a material pump includes a silencer body 100. An air inlet 110 is located on one side of the bottom of the silencer body 100, and an air outlet 120 is located at the bottom of the silencer body. Inside the silencer body, several partitions 130 divide the internal space into multiple chambers along the height direction. Several through holes 131 are provided on one side of each partition, and the through holes of adjacent partitions are staggered. This silencer device uses partitions with staggered through holes, allowing for rapid gas discharge while noise is reduced and canceled out within the chambers. The noise level is reduced from a maximum of 83.5 dB to 63.6 dB, resulting in good noise reduction, improved working environment, increased comfort, and improved employee health. It also reduces occupational health risks and minimizes safety and quality risks caused by communication difficulties.
[0022] Specifically, the partition can be set in four layers, and the internal space of the silencer cylinder is divided into a first chamber, a second chamber, a third chamber, a fourth chamber, and a fifth chamber in the height direction.
[0023] In this embodiment, each cavity is filled with sponge, which can absorb more noise.
[0024] In this embodiment, the silencer body is cylindrical, with an outer diameter of 180mm and a height of 500mm.
[0025] In this embodiment, the bottom of the silencer cylinder is provided with a drain port 140 to increase the drainage function and drain the condensate in time.
[0026] In this embodiment, a support foot 150 is fixedly connected to the bottom of the silencer body.
[0027] In this embodiment, the through holes of two adjacent partitions are located on opposite sides, that is, the through holes of the lower partition are located in the left area and the through holes of the upper partition are located in the right area; or the through holes of the lower partition are located in the right area and the through holes of the upper partition are located in the left area.
[0028] In this embodiment, the silencer body is made of stainless steel with a wall thickness of 3mm, which is rust-free and has high strength.
[0029] In this embodiment, the diameter of the air inlet is 16mm and the diameter of the air outlet is 10mm.
[0030] In this embodiment, the bottom of the silencer cylinder is concave spherical, and a valve is provided at the drain outlet.
[0031] The modified silencer device was verified by monitoring noise data for half a month under full-load operation of the material pump. The maximum value was taken from five measurements at each point. The noise level was reduced from the original maximum of 83.5dB to 63.6dB, which meets the national standards and noise improvement requirements.
