Utility model content
The purpose of this utility model is that: to solve existing venting of dust explosion plate fragment easy to form in venting of dust explosion, and these are broken
Sector-meeting the problem of be easy to causeing secondary injury, provides a kind of tearing type venting of dust explosion plate with explosion splashes.
The technical solution adopted in the utility model is as follows:
A kind of tearing type venting of dust explosion plate, including connection framework, the side of the connection framework are equipped with level-one venting of dust explosion layer, and described one
Cross release groove is offered on grade venting of dust explosion layer, the other side of the connection framework is equipped with second level venting of dust explosion layer, and the second level is let out
Quick-fried layer is equipped with protective net far from the side of connection framework, and thermal insulating material is filled between the level-one venting of dust explosion layer and second level venting of dust explosion layer
Material.
In above scheme, the connection framework includes the external frame of rectangle, is equipped with several longitudinal directions in the external frame
Bar and several transverse bars, form several hollow areas between the external frame, longitudinal rod and transverse bar, on the level-one venting of dust explosion layer
Form several venting of dust explosion portions correspondingly with hollow area, the center in each venting of dust explosion portion, the thermal insulating material is arranged in the release groove
Material is filled in hollow area.
In above scheme, the width of the release groove is 0.25mm.
In above scheme, the thermal insulation material is rock wool.
In above scheme, the second level venting of dust explosion layer, which is equipped with rectangular array close to the side of connection framework, has several circles recessed
It falls into.
In above scheme, the aperture of the protective net is octagon.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the utility model is by way of setting level-one venting of dust explosion layer and second level venting of dust explosion layer, by opening on level-one venting of dust explosion layer
If the mode of release groove, when the gas pressure in confined space steeply rises, when pressure value reaches P=1.15kPa, level-one is let out
Quick-fried layer is opened and is released stress along release groove schistostoma, and second level venting of dust explosion layer is crushed again after the buffering of level-one venting of dust explosion layer, control explosion
Generation, so that extent of the destruction is reached minimum, secondary injury can be effectively avoided, then by the setting of thermal insulation material, so that not
Influence the heat insulation effect usually used.
2. it is practical by forming hollow area in connection framework, the mode of thermal insulation material is filled in hollow area, is improved
The effect of heat preservation when usually using, at the same be arranged on level-one venting of dust explosion layer with the mode in the one-to-one venting of dust explosion portion in hollow area,
Subregion venting of dust explosion is realized, extent of the destruction is further reduced, effectively avoids the generation of secondary injury.
3. it is practical by way of it will discharge groove width and be set as 0.25mm, while guaranteeing venting of dust explosion effect, do not influence
Use usually.
4. the utility model by way of setting rock wool for thermal insulation material, plays the effect of heat preservation, while can be with
Play fire-retardant effect.
5. the utility model is by the setting of arc-shaped recess, so that the depth side being arcuately recessed when second level venting of dust explosion layer venting of dust explosion
To releasing stress, protective net is allowed effectively to intercept fragment.
