DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When implementing: Figure 1-4 As shown, a low-noise raw material screening device includes: a screening machine body 1, a feed pipe 101 is arranged on the top of the screening machine body 1, a centrifugal motor 102 is arranged on one side of the screening machine body 1, a mounting seat 104 is arranged on the bottom of the centrifugal motor 102, and one side of the mounting seat 104 is fixedly connected to the surface of the screening machine body 1; a first sound insulation component 2, the first sound insulation component 2 is arranged on one side of the screening machine body 1, and the first sound insulation component 2 is used to reduce the noise generated during the operation of the centrifugal motor 102; a second sound insulation component 3, the second sound insulation component 3 is arranged on the surface of the screening machine body 1, and the second sound insulation component 3 is used to reduce the noise transmission generated during the screening process.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the second sound insulation component 3 includes a mounting cover 301 arranged on the surface of the screening machine body 1, the screening machine body 1 is located on the inner side of the mounting cover 301, a vacuum chamber 302 is opened inside the mounting cover 301, and evenly distributed depressions 303 are opened on the inner side of the mounting cover 301. The inner side of the mounting cover 301 protrudes toward the screening machine body 1 to form evenly distributed protrusions 304, and the protrusions 304 and the depressions 303 are staggered. Evenly distributed convex strips 305 are fixedly connected to the inner side of the mounting cover 301, and a gap portion 306 is formed between the two convex strips 305. The convex strips 305 are sound-absorbing cotton material components;

[0023] The vacuum chamber 302 can be provided to reduce the noise generated during the material screening process by utilizing the characteristic that sound cannot be transmitted in a vacuum environment;

[0024] The staggered recesses 303 and protrusions 304 can initially form a reflective surface that is approximately wavy in shape, so that the sound waves of noise are reflected when they are transmitted to the recesses 303, and the sound waves reflected by the inner walls on both sides of the recesses 303 can offset each other to achieve a preliminary sound-absorbing effect. The arrangement of the convex strips 305 and the gap portions 306 can form an uneven reflective surface on the inner wall of the recess 303, so that the sound waves can be scattered when they are transmitted there, further eliminating the noise and improving the noise reduction effect. The convex strips 305 of the sound-absorbing cotton material component can absorb sound waves and effectively improve the sound-absorbing effect.

[0025] like Figure 1 and Figure 2 As shown, the first sound insulation component 2 includes a mounting shell 201 fixedly connected to the surface of the mounting cover 301, a sound insulation layer 202 is fixedly connected to the inner side of the mounting shell 201, the centrifugal motor 102 is arranged on the inner side of the sound insulation layer 202, the sound insulation layer 202 is a sound-absorbing cotton material component, a heat sink 103 is arranged on the surface of the centrifugal motor 102, one end of the heat sink 103 passes through the mounting shell 201, a heat exchange through hole is opened on the side of the mounting shell 201 away from the mounting cover 301, and a dustproof net is embedded and installed on the inner wall of the heat exchange through hole;

[0026] The arrangement of the heat exchange through hole and the dustproof net can increase the contact area between the inner side of the mounting shell 201 and the outside world, thereby ensuring the heat dissipation effect of the centrifugal motor 102. The heat dissipation block 103 further increases the contact area with the outside air, thereby improving the heat dissipation effect.

[0027] The sound insulation layer 202 of the sound-absorbing cotton material component can reduce the heat generated during the use of the centrifugal motor 102.

[0028] When the utility model is in use, the noise generated in the material screening process can form a nearly wavy reflection surface under the cooperation of the staggered recesses 303 and the protrusions 304, so that the sound waves of the noise are reflected when they are transmitted to the recesses 303, and the sound waves reflected by the inner walls on both sides of the recesses 303 can offset each other to achieve a preliminary sound-absorbing effect. The arrangement of the convex strips 305 and the gap portions 306 can form an uneven reflection surface on the inner wall of the recess 303, so that the sound waves can be scattered when they are transmitted there, further eliminating the noise and improving the noise reduction effect. The convex strips 305 of the sound-absorbing cotton material component can absorb sound waves, effectively improving the sound-absorbing effect, and cooperating with the vacuum chamber 302 to reduce the noise transmission after multiple attenuations, effectively reducing the noise generated during the use of the device.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
