Description
Technical field
The utility model relates to venting of dust explosion plate technique fields, and in particular to a kind of venting of dust explosion plate of sound-absorption and heat-insulation.
Background technique
Fire prevention venting of dust explosion plate is the construction material for constructing wall, roof with explosion hazard place etc., with city
The continuous reinforcement of cityization construction, people concentrate on indoor scene and gradually increase, fire-proof and explosion-proof for these public places
Safety has to reach good guarantee.And venting of dust explosion plate of preventing fires occurs in fire and does not have explosion time, can be formed to Fire Field
Certain flame retardant effect, and when explosion time occurs, venting of dust explosion plate, which can pop, to form fragment, abrupt release room pressure, reduces building
The degree of impairment of object.
But existing venting of dust explosion plate sound-absorbing effect is poor, soundproof effect is poor in routine use, and explosion time occurs to explosion
The absorption of sound is also very poor, causes noise pollution.
Therefore, designing a kind of fire prevention venting of dust explosion plate that soundproof effect is good has important research meaning.
Utility model content
The purpose of this utility model is that:, in routine use sound insulation poor for the existing venting of dust explosion plate sound-absorbing effect of solution
The problem of effect difference provides a kind of venting of dust explosion plate of sound-absorption and heat-insulation.
The technical solution adopted in the utility model is as follows:
A kind of venting of dust explosion plate of sound-absorption and heat-insulation, including venting of dust explosion base, rectangular array has several ventings of dust explosion in the venting of dust explosion base
Area, the venting of dust explosion district center offer cross release groove, and the side of the venting of dust explosion base is equipped with sound absorbing layer, the sound absorbing layer
Including sound-absorbing substrate, the sound-absorbing substrate is equipped with several abatvoixs far from the side of venting of dust explosion base, and the abatvoix is along sound-absorbing base
The length direction uniform pitch of plate is arranged, and there are gap between two groups of adjacent abatvoixs, the other side of the venting of dust explosion base is set
There is protective layer.
In above scheme, the protective layer includes the protective net that several groups are stacked, the aperture of two adjacent groups protective net
In shifting to install.
In above scheme, the aperture of the protective net is octagon.
In above scheme, the width of the release groove is 0.25mm.
In above scheme, rock wool is filled between the sound-absorbing substrate and venting of dust explosion base.
In above scheme, the material of the abatvoix and sound-absorbing substrate is polyester fiber.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the utility model in such a way that abatvoix is arranged in uniform pitch on sound-absorbing substrate, can be reinforced to sound energy
Absorb, by stayed between two adjacent groups abatvoix it is apertured in the way of so that sound carries out multiple reflections in gap, thus
The consumption for strengthening sound energy, improves the sound-absorbing effect of venting of dust explosion plate, solves the problems, such as that existing venting of dust explosion plate sound-absorbing effect is poor, simultaneously
In such a way that several venting of dust explosion areas are arranged in rectangular array in venting of dust explosion base, subregion venting of dust explosion is realized, explosion is avoided
The huge destruction of Shi Zaocheng, thus the problem of secondary injury occurs.
2. the utility model by way of setting multiple groups protective net for protective layer, realizes the fragment formed to venting of dust explosion
Comprehensive interception is carried out, the generation of secondary injury is avoided.
3. the utility model will be by way of it will discharge groove width and be set as 0.25mm, while guaranteeing venting of dust explosion effect, no
Influence use usually.
4. the utility model by way of being filled with rock wool between sound-absorbing substrate and venting of dust explosion base, ensure that well
The effect of heat-insulating flame-retardant.
