On the buffering suface of above-mentioned dash plate, be equipped with rubber layer.
Ground dedusting system superpressure explosion venting device of the present utility model, by connecting arm plate by explosion venting valve short tube, sealing valve plate and buffer gear connect as one, and between explosion venting valve short tube and sealing valve plate, sealed strip is installed, realization is tightly connected, by connecting arm plate and the hinged assurance sealing of sealing valve plate valve plate, under system pressure, automatically open venting of dust explosion, and utilize buffer gear to guarantee sealing valve plate proper reset and flexible movements after pressure release, without jam, good sealing effect of the present utility model, guarantee the sealing effectiveness of system under normal circumstances, and safe and reliable, guarantee security of system production and personnel safety, securing system exempts from blast infringement, safety coefficient is high, after completing pressure release effect, also can automatically close, without manual reversion, can not affect normal production, increase work efficiency, in addition its maintenance rate and maintenance cost also can reduce greatly, economical and practical, be suitable for industrial applications.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the structural representation of buffer gear 5 in Fig. 1.
Embodiment
Now by reference to the accompanying drawings the technical solution of the utility model is further described, but the utility model is not limited only to following enforcement situation.
As shown in Figure 1, the ground dedusting system superpressure explosion venting device of the present embodiment is to be connected and composed by explosion venting valve short tube 1, sealing valve plate 2, hinge 3, connecting arm plate 4, buffer gear 5, pressing plate 6 and sealed strip 7.
In the present embodiment, the entrance of explosion venting valve short tube 1 is provided with ring flange, by ring flange, be connected with wallboard outside cleaning shaft or each storehouse of fly-ash separator, the outlet of explosion venting valve short tube 1 is processed as ramp structure, the pitch angle of outlet is 75 °, the exit of explosion venting valve short tube 1 is provided with sealing valve plate 2, sealing valve plate 2 is to adopt whole punching press to make the stainless steel plate of moulding, good rigidly, surfacing distortion is little, can play better sealing effectiveness, referring to Fig. 2, inner side at sealing valve plate 2 is provided with sealed strip 7 around explosion venting valve short tube 1 outlet periphery, sealed strip 7 is, on the trim of sealing valve plate, the mounting bar contacting with explosion venting valve short tube 1 is installed, this mounting bar is flats, in the inner side of mounting bar, pressing plate 6 is installed, with M8 threaded fastener, pressing plate 6 is connected with sealing valve plate 2, in the middle of mounting bar is clamped in, reach sealed strip 7 object fixing and assurance good sealing effect is installed.The sealing-ring of the present embodiment is adopt high-temperature carbon fiber to fill copper wire and through surface, hang silica gel treatment, have high temperature resistant, corrosion-resistant, wear-resistant, the advantage of good airproof performance.On the outer wall of sealing valve plate 2, hinge 3 bearings are installed, sealing valve plate 2 is hinged by hinge 3 and connecting arm plate 4, one end of connecting arm plate 4 is welded on the tube wall of explosion venting valve short tube 1, hinge 3 is fixed on the curved boom near 1 outlet of explosion venting valve short tube by bearing pin, guarantees that sealing under normal circumstances valve plate 2 is connected with explosion venting valve short tube 1 exit seal.Between two connecting arm plates 4, be welded with mounting plate 5-3, on mounting plate 5-3, with screw rod, be fixed with four isometric spring 5-2 respectively, the end of four screw rods and dash plate 5-1 firm welding, be equipped with rubber layer on the dash plate 5-1 of the present embodiment, strengthens the surge capability of dash plate 5-1.
