DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.
[0024] Embodiment 1:
[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The high critical frequency sound insulation explosion-proof swing door comprises a door frame 1 and a broadband high sound insulation panel 101 rotatably connected to the door frame 1, a door lock body 102 is arranged on the broadband high sound insulation panel 101, and further comprises: a rubber seal arranged on the door frame 1 and used to increase the sealing performance of the connection between the door frame 1 and the broadband high sound insulation panel 101; a wrapping airbag 2 arranged around the outer wall of the broadband high sound insulation panel 101, wherein a sealing groove 201 used in conjunction with the wrapping airbag 2 is opened on the inner wall of the door frame 1; a booster pump 202 fixedly mounted on the broadband high sound insulation panel 101; and a pipe 203, one end of which is fixedly connected to the output end of the booster pump 202, and the other end of which is fixedly connected to the wrapping airbag 2.
[0026] The rubber seal comprises a sealing pad 103 , which is fixedly mounted on the inner wall of the door frame 1 and fits with the broadband high sound insulation panel 101 .
[0027] The device also includes an activated carbon filter 204 , which is fixedly installed in the input end of the booster pump 202 .
[0028] It also includes an exhaust pipe 3 fixedly connected to the wrapped airbag 2, and a valve switch 301 is provided on the exhaust pipe 3.
[0029] When in use, the sealing gasket 103 on the inner wall of the door frame 1 fits with the broadband high sound insulation panel 101, thereby increasing the sealing of the connection between the door frame 1 and the broadband high sound insulation panel 101, thereby reducing sound leakage and improving the sound insulation effect. Then, the valve switch 301 on the exhaust pipe 3 is closed, and the booster pump 202 is turned on. The booster pump 202 absorbs external gas and transports the gas into the wrapped airbag 2 through the pipe 203, so that the wrapped airbag 2 expands and fits tightly with the sealing groove 201. A one-way valve is provided on the pipe 203, which further increases the sealing of the connection between the door frame 1 and the broadband high sound insulation panel 101, thereby effectively reducing sound leakage and further improving the sound insulation effect.
[0030] At the same time, when the external gas passes through the input end of the booster pump 202, it comes into contact with the activated carbon filter 204. Since the activated carbon has a developed void structure and rich microporous tissue inside, these microporous tissues have a strong adsorption force field. When the gas comes into contact with the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas and effectively preventing the gas from carrying particulate matter impurities into the wrapped airbag 2.
[0031] Embodiment 2:
[0032] Reference Figure 1 , Figure 5 , a high critical frequency sound insulation and explosion-proof swing door, which is basically the same as Example 1, and further, a pressure relief pipe 302 is fixedly connected to the exhaust pipe 3, and a pressure relief valve is arranged on the pressure relief pipe 302; when the pressure in the wrapped airbag 2 is increased, when the pressure increased into the wrapped airbag 2 is greater than the pressure relief value set by the pressure relief valve, the pressure relief valve automatically opens to relieve the pressure. At this time, part of the high-pressure gas increased into the wrapped airbag 2 is discharged through the pressure relief pipe 302, thereby keeping the pressure in the wrapped airbag 2 constant, preventing the pressure increased into the wrapped airbag 2 from being too high, causing damage to the wrapped airbag 2, and then the boost pump 202 can be turned off.
[0033] Embodiment 3:
[0034] Reference Figure 1 , Figure 3 and Figure 5 The high critical frequency sound insulation explosion-proof swing door is basically the same as that of Example 1. Furthermore, a vacuum cavity is opened between the inner and outer walls of the broadband high sound insulation panel 101; due to the unrestrained propagation in the vacuum cavity, the medium and low frequency noise with strong penetrating power can be reduced, thereby achieving the sound insulation effect.
[0035] A high sound insulation noise reduction board 401 is arranged in the vacuum chamber, and broadband sound absorption and noise reduction bodies 4 are filled on both sides of the high sound insulation noise reduction board 401 in the vacuum chamber; by arranging the high sound insulation noise reduction board 401 and the broadband sound absorption and noise reduction body 4, the frequency of noise can be effectively reduced, thereby achieving a good noise reduction effect.
[0036] Embodiment 4:
[0037] Reference Figure 1 , Figure 2 , a high critical frequency sound insulation explosion-proof swing door, which is basically the same as that of Example 1, and further, the broadband high sound insulation panel 101 is made of galvanized steel plate; since the surface of the galvanized steel plate is covered with a zinc layer, the zinc layer can effectively prevent oxygen, moisture and other substances from entering the steel, thereby slowing down the corrosion rate of the steel, thereby extending the service life of the broadband high sound insulation panel 101;
[0038] Since galvanized steel plate is a very durable material, it will not easily burn even if it is cracked or damaged. Secondly, galvanized steel plate does not generate static electricity, so it is not easy to cause an explosion, which can effectively avoid dangerous situations such as explosions caused by static electricity.
[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
