Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
An explosion-proof plate with a noise reduction function is disclosed, as shown in fig. 1-2, and comprises an outer surface layer 1, a middle layer 2 and an explosion-proof layer 3 which are sequentially stacked, wherein a plurality of groups of sound inlet holes 100 are arranged on the outer surface layer 1, corresponding noise reduction structures are arranged on the middle layer 2 corresponding to each group of sound inlet holes 100, each noise reduction structure comprises a noise reduction pipeline 21 which is arranged in a folding manner, one end of each noise reduction pipeline 21 is communicated with the corresponding sound inlet hole 100, the other end of each noise reduction pipeline 21 is arranged in a closed manner, and each noise reduction pipeline 21 further comprises a plurality of groups of noise reduction units; the aperture of both ends of each group of silencing units is larger than that of the middle part. Sound propagates in the sound-deadening duct 21 after entering the sound-deadening structure through the sound-inlet hole 100; because the folding setting of amortization pipeline 21 and the aperture constantly changes in the amortization pipeline 21, lead to like this sound aggravate in the transmission process with the 21 lateral walls between the collision, its energy constantly is consumed, therefore just sound can not appear spreading from the explosion-proof board other end, has ensured that the explosion-proof board can have good noise cancelling effect.
In order to improve the stability of the whole silencing pipe 21 and the whole middle layer 2, furthermore, the silencing units are symmetrically arranged, and each group of silencing units is narrowed at the folding position. As shown in fig. 3, the aperture at the interface at the two ends of each group of silencing units is a and c, while the aperture at the folding position of the silencing units is b, and under the condition that the silencing units are symmetrically arranged, a is equal to c, and simultaneously a is greater than b; at the position where the aperture of the silencing unit is a, the aperture gradually decreases when the silencing unit reaches the folded position.
In order to better improve the overall sound absorption effect, the middle layer 2 is further provided with polyester sound absorption cotton, and the polyester sound absorption cotton is arranged to surround the sound absorption pipeline 21. After the sound cotton is inhaled to the setting polyester, because the sound cotton is inhaled to the polyester has good sound effect of inhaling, can improve holistic sound absorbing performance like this, the sound cotton is inhaled to the polyester simultaneously still has good heat insulating ability, fire resistance and impact resistance, has promoted the whole comprehensive properties of explosion-proof board.
In order to make the sound enter the silencing pipe 21 through the sound inlet hole 100 as much as possible, further, the sound inlet hole 100 is funnel-shaped, the end with the larger opening of the sound inlet hole 100 is arranged on the surface far away from the middle layer 2, and the end with the smaller opening of the sound inlet hole 100 is directly connected with the silencing pipe 21.
In order to further improve the overall sound absorption performance, the outer surface layer 1 is also provided with rock wool. Rock wool not only has and plays good sound effect of inhaling, can also play the effect that keeps warm, separate the fire simultaneously, has further improved the holistic blast resistant ability of explosion-proof board.
