Detailed Description
Fig. 1 and 2 schematically show an explosion venting device with a guide device for dust explosion prevention according to an embodiment of the present invention. As shown in fig. 1 and 2, the explosion venting device with the guiding device for dust explosion prevention comprises a flange frame 1, an explosion venting plate 2, a steel wire guiding net 3 and a sealing film.
Three weakening seams which are connected end to end in sequence are cut on two stainless steel plates which are attached to each other, and a flange frame 1 positioned at the periphery and an explosion venting plate 2 positioned at the middle part are formed. Specifically, three weakening lines are vertically arranged in sequence, and a square explosion venting plate 2 and a square flange frame positioned around the explosion venting plate 2 are formed in the middle of the stainless steel plate. Wherein the three sides of the explosion venting plate 2 cut with the weakening slits are respectively parallel to the three sides of the flange frame 1. The three weakening slits are in the shape of a dashed line. The outer edges of the three edges of the explosion venting plate 2 cut with the weakening slits are connected with the inner edge part of the flange frame 1, and the connection between the explosion venting plate 2 and the flange frame 1 can be maintained when no explosion occurs. When no explosion occurs, the flange frame 1 and the explosion venting plate 2 are positioned on the same plane, so that the sealing performance of the whole device can be maintained when no explosion occurs. In order to prevent explosion from occurring, the explosion venting plate 2 is exploded, and one side A of the explosion venting plate 2 which is not cut is integrated with the flange frame 1. Specifically, the explosion venting plate 2 is rectangular, and one longer side of the explosion venting plate 2 is integrated with the flange frame 1. On the one hand, the explosion venting plate 2 is stably connected to the flange frame 1, on the other hand, the explosion venting plate 2 can stably move in a fan shape, and in practical application, the explosion venting plate 2 can also have other various shapes when the conditions are met. A plurality of screw holes 11 are formed in the flange frame 1, and connection with other components is achieved through the screw holes 11. The flange frame 1 is provided with a guide piece. The guide piece has better effect under the condition of elasticity, and plays a buffering role on the explosion venting plate 2. A rubber sheet or a steel wire mesh having elasticity or other sheet-like members that can block the explosion venting plate 2 from being excessively separated from the flange rim 1 may be used. In this embodiment, the elastic guide is selected from a guiding wire mesh 3 having elasticity. The guiding steel wire mesh 3 is positioned on the back surface of the explosion venting plate 2 subjected to explosion impact force. After explosion, the guide steel wire mesh 3 blocks the explosion venting plate 2 from being completely separated from the flange frame 1. In addition, the guiding steel wire mesh 3 has elasticity and has a buffering effect on the explosion venting plate 2. After explosion, the uncut side A of the explosion venting plate and the flange frame 1 are of an integrated structure, so that the explosion venting plate cannot be separated, the guiding steel wire mesh 3 covers the side A of the explosion venting plate and a part of the region of the explosion venting plate 2 extending from the side A to the rest, and the explosion venting plate 2 can move in a sector track with the side A as the center. The area of the guide steel wire mesh 3 covering the explosion venting plate 2 determines the separation angle of the explosion venting plate 2 and the flange frame 1. In practical application, the coverage area of the guiding steel wire mesh 3 can be adjusted according to the required angle, and the larger the coverage area is, the smaller the angle of the fan-shaped track of the explosion venting plate 2 is, in this embodiment, the guiding steel wire mesh 3 covers the area of more than half of the area of the explosion venting plate 2. After explosion, the separation angle of the explosion venting plate 2 and the flange frame 1 is smaller, so that the damage to the surrounding environment caused by the larger separation angle is avoided.
After explosion, the rest edges of the explosion venting plate 3 are separated from the flange frame 2 along the direction of the explosion impact force, and the guiding steel wire mesh 3 blocks the separation movement of the explosion venting plate 2 and the flange frame 1. Sealing films between two stainless steel plates are adhered. And plays a role of sealing. After no explosion, the sealing film is in an integrated structure. After explosion, the sealing film is torn off when the explosion venting plate is separated from the flange frame.
As shown in fig. 3 and 4, after the explosion venting plate without the steel wire guide net 3 explodes, when the explosion venting plate 2 receives the overpressure generated by the explosion of the dust remover, the flange frame 1 can be kept at the original position, and the middle explosion venting plate 2 can be broken by the overpressure impact and is completely opened in a fan-shaped state. As shown in fig. 1 and 2, the explosion venting plate 2 provided with the steel wire guide net 3 is subjected to overpressure generated by explosion of the dust remover, the flange frame 1 can be kept at the original position, the middle explosion venting plate can be broken by the overpressure impact and opened in a fan-shaped state, but is wrapped by the guide steel wire net, and the explosion venting plate 2 can only be opened according to a set angle, so that the safety of nearby personnel and equipment is protected.
The foregoing are merely some embodiments of the invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the inventive concept of the present invention.
