Description
Technical field
The present invention relates to a kind of explosion proof door disk-sucking device, belong to the explosion proof door technical field.
Background technique
At present, in Coal Pulverizing System of Thermal Power Plant, because the intrinsic characteristic of coal dust, the phenomenon of very easily blasting is having a strong impact on the device security reliable operation.So explosion proof door is installed at the position that needs to have explosion risk at pulverizing system, the pressure that the blast that utilizes this equipment to discharge might to produce produces is to protect the person, equipment or parts safety.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby a kind of explosion proof door disk-sucking device is provided, can discharge the pressure that blast produces, safe and reliable, improved safety coefficient.
According to technological scheme provided by the invention, the explosion proof door disk-sucking device comprises interior panel, outer panel and base plate, interior panel is fixed on the plate upper surface center by the first screw, outer panel is fixed in the plate upper surface outer ring by the 3rd screw, it is characterized in that: also comprise decompression plate, magnet and fireproof plate, fireproof plate is fixed on the base plate lower surface by the 3rd screw, and magnet is fixed on plate upper surface by the second screw, and the magnet upper end connects the decompression plate.The first vent of perforation is established at interior panel, base plate and fireproof plate center, and decompression plate center is provided with the second vent.
Described fireproof plate adopts asbestos material to make.
Described magnet is between interior panel and outer panel.
Described the first vent and the second vent are communicated with,
The diameter of described the first vent is greater than the diameter of the second vent.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; The antiknock anti-pressure ability is strong, and is safe and reliable; Cost is low; Improved safety coefficient.
Description of drawings
Fig. 1 is structural representation of the present invention.
Panel, the outer panel of 4-, 5-base plate, 6-fireproof plate, 7-the first screw, 8-the second screw, 9-the 3rd screw, 10-the first vent, 11-the second vent in description of reference numerals: 1-decompression plate, 2-magnet, the 3-.
Embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, the present invention mainly comprises decompression plate 1, magnet 2, interior panel 3, outer panel 4, base plate 5 and fireproof plate 6.
Fireproof plate 6 is fixed on base plate 5 lower surfaces by the 3rd screw 9, and fireproof plate 6 adopts asbestos material to make, and the high temperature that prevent exploding produces spreads out of.
Interior panel 3 is fixed on base plate 5 upper surface centers by the first screw 7, and outer panel 4 is fixed in base plate 5 upper surface outer rings by the 3rd screw 9.
Magnet 2 is fixed on base plate 5 upper surfaces by the second screw 8, and magnet 2 is between interior panel 3 and outer panel 4.
Magnet 2 upper ends connect decompression plate 1.
The first vent 10 of perforation is established at interior panel 3, base plate 5 and fireproof plate 6 centers, and decompression plate 1 center is provided with the second vent 11.Described the first vent 10 and the second vent 11 are communicated with, and the diameter of the first vent 10 is greater than the diameter of the second vent 11.
Working principle of the present invention is: when work, when coal dust was blasted, the impact force that blast produces promoted door closure and moves upward.The door closure Compress Spring, connecting tube slides on the disk-sucking device by lining, and promotes decompression plate 1 up.Magnetic attraction by 2 pairs of decompressions of magnet plate 1 overcomes the pressure that blast produces.Fireproof plate 6 is used for stopping or cushioning the flare of scurrying out that the flame ejection causes fire during prevent exploding, and the protection operator exempt from hot air flow and burn.Compact structure of the present invention is reasonable, and cost is low, uses safety and stability, has improved the safety coefficient of work.
