Abstract
A rupture disc device of a flammable and explosive dust device comprises a porous anti-vacuum bracket, a sealing film and a slotted rupture disc. The sealing film is arranged between the porous anti-vacuum bracket and the slotted rupture disc. The slotted rupture disc controls blasting pressure. The sealing film plays the sealing role. The porous anti-vacuum bracket prevents device vacuum. The rupture disc of the utility model responds to dynamic pressure increase quickly. Dust hardly deposits in the rupture disc and influences the property of the rupture disc. At the same time, the explosion danger brought by dust deposition is eliminated. The rupture disc device is particularly applicable to the safe explosion prevention of low pressure and ultra-low pressure flammable and explosive medium devices.
Description
Technical field
The utility model relates to a kind of blasting piece device, relates in particular to the blasting piece device that is applied to easily produce the dust system of blast.
Background technique
Because dust equipment intensity is low, require the rupture disk relieving pressure very low mostly, and the bore of releasing is bigger, the rupture disk of the sector adopts the combined rupture disk that cracks mostly at present.The tradition rupture disk that cracks has a small amount of very narrow saturating seam on the vacuum cartridge, the dust medium accumulates between vacuum cartridge and the sealing film easily, has to clear out of, and dust is cumulative as a result, if there is moisture in medium, then has one deck attachment on carriage; Because saturating seam size is little, when boosting rapidly, resistance is big, influences the responsiveness of rupture disk in addition.Dust gathers on the one hand blast easily, influences the receptance of rupture disk to boosting rapidly on the other hand, influences the rupture disk performance.
Summary of the invention
The utility model purpose is to overcome the crack deficiency of rupture disk of tradition, utilize carriage with holes that dust can't be accumulated on the carriage, has improved the upper strata rupture disk simultaneously to the responsiveness of boosting rapidly and a kind of inflammable and explosive dust equipment blasting piece device that designs.
The technological scheme that its technical problem that solves the utility model adopts is: device comprises that porous prevents vacuum cartridge, sealing film and the rupture disk that cracks, sealing film is arranged on the anti-vacuum cartridge of porous and cracks between the rupture disk, crack rupture disk controlled blasting pressure, sealing film seals the anti-vacuum cartridge opposing of porous equipment vacuum.
This structural feature is that the anti-vacuum cartridge of porous can't accumulate between carriage and the rupture disk dust medium, if any gathering, has just come off by the hole; Sealing film is a smooth surface in addition, also is difficult for attaching powder.The anti-vacuum cartridge of porous not only plays the vacuum supporting effect to sealing film, and the anti-vacuum cartridge of porous also is a kind of rupture disk simultaneously, and certain bursting pressure is arranged, and in rupture disk explosion moment, vacuum cartridge is explosion also, opens leakage path.Several diameters of processing are the hole of 10-15mm on the anti-vacuum cartridge of porous, and the quantity in hole is determined by the vacuum cartridge size.
The beneficial effects of the utility model are: this device can realize that rupture disk is fast to dynamically boosted speed of response, dust is difficult for accumulating in the rupture disk, influences the rupture disk performance, has also eliminated dust deposit simultaneously and has brought explosion risk.This blasting piece device is particularly suitable for the safety anti-explosive of low pressure, the inflammable and explosive medium apparatus of super-low voltage.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the utility model device.
Fig. 2 is that the A of the utility model device is to schematic representation.
Among the figure, the rupture disk that 1. cracks, 2. sealing film, the 3. anti-vacuum cartridge of porous.
Embodiment
As shown in Figure 1 and Figure 2, this inflammable and explosive dust equipment comprises that with blasting piece device embodiment porous prevents vacuum cartridge 3, sealing film 2 and the rupture disk 1 that cracks, sealing film 2 is arranged on the anti-vacuum cartridge 3 of porous and cracks between the rupture disk 1, crack rupture disk 1 controlled blasting pressure, sealing film 2 seals the anti-vacuum cartridge 3 opposing equipment vacuum of porous.
Hole on the anti-vacuum cartridge 3 of porous makes the dust medium can't accumulate to metal porous anti-vacuum cartridge 3 and cracks between the rupture disk 1, if any gathering, has just come off by the hole; Sealing film 2 is a smooth surface in addition, also is difficult for attaching powder.The anti-vacuum cartridge 3 of porous not only plays the vacuum supporting effect to sealing film 2, and the anti-vacuum cartridge 3 of porous has certain bursting pressure also as a kind of rupture disk simultaneously, and in rupture disk explosion moment, porous is prevented also explosion of vacuum cartridge, opens leakage path.Processing some diameters are the hole of 10-15mm on the anti-vacuum cartridge of porous, and the quantity in hole is determined by the vacuum cartridge size.
The utility model is not limited to the foregoing description, and protection domain of the present utility model is all classified in any equivalent concepts or change in the technical scope that the utility model discloses as.
