Embodiment 1

[0027] see Figure 1~3 , a ventilation device for the prison system based on silent technology, comprising a wall 1, the interior of the wall 1 is provided with an air transfer chamber 2, the bottom wall of the inner cavity of the air transfer chamber 2 is inclined, and the air transfer chamber The left end of the inner cavity of the cavity 2 is uniformly provided with some air outlet holes 8, the left side end of the air outlet hole 8 is provided with an air outlet protective net 9, and the top right end of the air transfer chamber 2 is provided with an air inlet hole 10 , the air intake hole 10 is provided with an air intake device 11, the air intake hole 10 and the air intake device 11 are threaded, and the bottom end of the right side of the air transfer chamber 2 is provided with a dust discharge hole 12, so The dust discharge hole 12 is corresponding to the lowest end of the inner cavity bottom wall of the air transfer chamber 6 , and the right end of the dust discharge ...

Embodiment 2

[0030] This embodiment is a further elaboration on the basis of Embodiment 1. The inner cavity of the air intake tube 111 is provided with an air intake protection net 1111 and an air suction fan 1112, and the air intake protection net 1111 is arranged on the suction fan 1112. On the right side, the outer side of the suction fan 1112 is evenly provided with several connecting rods 1113, and the other end of the connecting rods 1113 is fixedly connected to the inner cavity wall of the air intake passage 111, and the outer circular surface of the air intake cylinder 111 A side close to the limiting plate 113 is provided with bayonet pins 1114 symmetrically up and down, and the right side end of the inner cavity side wall of the silencer 112 is provided with a slot 1121 matched with the bayonet pin 1114, and the inner side end of the slot 1121 There is a card slot 1122 that is matched with the bayonet pin 1114 through the connection. The slot 1121 and the card slot 1122 are in a p...

Embodiment 3

[0032] This embodiment is a further elaboration on the basis of Embodiment 2. The sound-absorbing cylinder 112 includes an outer protective layer 1123, a sound-insulating layer 1124, a sound-absorbing layer 1125, and an inner insulating layer 1126. The outer protective layer 1123 is provided with a sound-insulating layer 1124, The inner sound-absorbing layer 1124 is provided with a sound-absorbing layer 1125, and the sound-absorbing layer 1125 is provided with an inner insulating layer 1126. The sound-insulating layer 1124 is made of a sound-insulating board, and the sound-absorbing layer 1125 is made of sound-absorbing cotton. As a result, the noise is absorbed by the sound-absorbing layer 1125, and at the same time, the sound-insulating layer 1124 is used to limit the diffusion of the noise. The two composite methods cooperate with each other to absorb and isolate the noise to the greatest extent and reduce the impact of the noise to the greatest extent.

Abstract

The invention discloses a ventilating device on the basis of noiseless silent technologies for prison systems. The ventilating device comprises a wall. An air transfer cavity is arranged inside the wall, the bottom wall of an inner cavity of the air transfer cavity is obliquely arranged, a plurality of air outlet holes are uniformly formed in the left side end of the inner cavity of the air transfer cavity, air outlet protective nets are arranged at the left side ends of the air outlet holes, an air inlet hole is formed in the top of the right side end of the air transfer cavity, an air inletdevice is arranged in the air inlet hole and comprises an air inlet barrel and a sound attenuation barrel, a limit plate which is matched with the air inlet hole is communicated and connected with theright side end of the air inlet barrel, and the sound attenuation barrel which is matched with the limit plate sleeves the air inlet barrel. The ventilating device has the advantages that clamp pinsare matched with an insertion groove and a clamp groove, accordingly, the sound attenuation barrel can be mounted and detached, and can be directly replaced once the sound attenuation barrel is damaged, and the ventilating device is quite convenient to apply; floating dust particle impurities in air can be filtered by a dust filter screen and an activated carbon layer, accordingly, the quality ofthe air can be improved, and floating dust particles generated after the floating dust particle impurities are filtered can directly fall on the bottom wall of the inner cavity of the air transfer cavity, and can be discharged via a dust discharge hole.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a ventilation device for a prison body system based on silent technology. Background technique [0002] Prison in a broad sense refers to places where all prisoners are held, including prisons, detention centers, detention centers, etc. Prison in a narrow sense refers to criminals who have been sentenced to death with a two-year suspension of execution, life imprisonment, or fixed-term imprisonment in accordance with the provisions of the Criminal Law and the Criminal Procedure Law. Implement the principle of combining punishment with reformation, education and labor, and transform criminals into law-abiding citizens. The competent authority for prisons is the Prison Service, and the highest administrative authority is the Ministry of Justice. [0003] Prisons have a distinct class character. The class nature of prisons is the fundamental attribute of prisons. Prisons are...
