DETAILED DESCRIPTION

[0021] 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.

[0022] The utility model embodiment provides a pulverizer impurity removal silencer, such as Figure 1-Figure 6 As shown, it includes a silencer 1 and sound-absorbing cotton 2; a debris-removing opening 5 is arranged at the top of the silencer 1, the sound-absorbing cotton 2 is arranged on the inner wall of the silencer 1, and a silencer structure 3 is installed inside the silencer 1; a mounting sleeve 4 is arranged at the bottom end of the silencer 1, and an auxiliary structure 6 is arranged on one side of the mounting sleeve 4.

[0023] Specifically, in this embodiment: when using the silencer 1, through the setting of the silencer structure 3, a silencer treatment can be performed when the metal impurities are discharged, and through the setting of the auxiliary structure 6, a switch can be performed on the mounting sleeve 4, so that the silencer 1 can accumulate the metal impurities before discharging, or can continue to discharge without accumulation, making it more convenient to collect metal impurities.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 6 As shown: the silencer structure 3 includes a through hole 301, a fixed block 302, a buffer block 303 and a silencer sleeve 304. The silencer sleeve 304 is installed inside the silencer tube 1. The fixed block 302 is installed inside the silencer sleeve 304. The buffer block 303 is arranged at the top of the fixed block 302. The bottom end of the silencer sleeve 304 is provided with a through hole 301. The buffer block 303 is made of rubber. The bottom end of the buffer block 303 is fixed to the top end of the fixed block 302. The buffer block 303 is conical in shape.

[0025] Specifically, in this embodiment: when metal impurities fall into the interior of the silencer sleeve 304, the rubber buffer block 303 can reduce the speed of the metal impurities, and make the metal impurities with reduced speed fall through the gap between the fixed block 302 and the silencer sleeve 304, so as to achieve the effect of slowing down the speed of the metal impurities. The slowed metal impurities then fall to the bottom of the silencer 1 through the through hole 301, thereby achieving a sound-absorbing effect by reducing the speed of the metal impurities, and through the use of the sound-absorbing cotton 2, a secondary sound-absorbing can be performed, realizing a multiple sound-absorbing processing work, so that the sound-absorbing effect is better.
