Can absorption, by stayed between two adjacent groups abatvoix it is apertured in the way of so that sound carries out multiple reflections in gap,
To strengthen the consumption of sound energy, the sound-absorbing effect of venting of dust explosion plate is improved, 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
Huge destruction is caused when generation, so that the problem of secondary injury occurs, is connected by the connector and second on the first link block
The link slot cooperation on block is connect, so that it is detachable between venting of dust explosion plate, when explosion time occurs, convenient for utilizing unspoiled part venting of dust explosion
Plate has saved resource, solves existing venting of dust explosion plate unitary design, causes the problem that economic cost is high.
2. in the utility model, the connector includes the main card tooth for being set to middle part and the pair for being set to main card tooth two sides
Latch, main card tooth two sides are provided with wedge angle, and the end of the vice card head is provided with arc angling.By the setting, pass through
The cooperation of main card tooth and vice card tooth, so that the connection between venting of dust explosion plate is more stable.
3. 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.
4. 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.
5. 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.
