Embodiment Construction

[0016] The technical solutions in the embodiments of the present invention are further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] like figure 1 As shown, according to a specific embodiment of the present invention, a new type of explosion-proof door structure is provided. The new type of explosion-proof door structure includes a valve body 1, a sealing gasket 2, a door cover 3, a universal joint 4, a spring 5, a door lever 6, an upper Cover 7, Disk 8.

[0018] In the embodiment of the present invention, the universal joint 4 of the new explosion-proof door structure connects the door rod 6 and the door cover 3, the spring 5 connects the upper cover 7 and the door cover 3, and the new explosion-proof door with the universal joint is installed, and the door cover is subjected to a certain pressure. After detonation, it can be automatically in place. After continuous detonation, the door rod and door cover wi...

Abstract

The invention provides a novel explosion door structure, the novel explosion door provided with a universal joint can automatically reset after the door cover is detonated under certain pressure, the door rod and the door cover cannot deform after continuous detonation, and the door rod and the door cover can be continuously pressed on the original sealing gasket, so that a better sealing effect is achieved. The sealing gasket adopts a structure that the lower part of the cross section is U-shaped and the upper part is triangular, a sealing structure is adopted among the valve body, the sealing gasket and the door cover, the sealing gasket is placed on a U-shaped groove of the valve body, the door cover is pressed into the sealing gasket, the door cover adopts a triangular structure, and the valve body, the sealing gasket and the door cover are tightly pressed and connected, so that the contact surface is larger, the sealing effect is better, and larger pressure can be borne; the sealing gasket is made of a graphite packing material, is low in cost, has a better sealing effect at a high temperature for a long time and is simple to replace. The novel explosion-proof door adopts a chromium plating process, and is better in corrosion resistance and wear resistance. By means of the technical scheme, the technical problems that in the prior art, when an explosion door returns, resetting is not accurate, and sealing is not tight are solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an automatic opening and closing explosion-proof door device for a coal mill. Background technique [0002] The automatic opening and closing explosion-proof door device is widely used in electric power, petrochemical and other fields, which provides a guarantee for the safe operation of coal and pulverizing system equipment. After the system explodes, the automatic opening and closing explosion-proof door device needs to be reset in time and accurately after opening in order to prevent air backflow and secondary explosion of the system. Serious deformation, resulting in inaccurate return and poor sealing, may cause damage to the explosion-proof door after one detonation, and a new explosion-proof door needs to be replaced. SUMMARY OF THE INVENTION [0003] The invention provides a novel explosion-proof door structure, which can solve the serious deformation of the door ro...
