Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention.

[0019] Such as figure 1 As shown, a novel explosion-proof door structure is provided according to a specific embodiment of the present invention, and the novel explosion-proof door structure includes a valve body 1, a sealing strip 2, a door cover 3, a column 4, a guide column 5, a guide sleeve 6, and a spring 7 , Adjusting nut 8, upper cover 9, disk 10.

[0020] In the embodiment of the present invention, the guide sleeve 6 of the novel explosion-proof door structure is fixed on the upper cover 9, one end of the guide post 5 is fixed on the door cover 3, and the other end is connected to the guide sleeve 6, which can move up and down, and the guide post guide sleeve is installed. The new type of explosion-proof door can automatically return to its original position after the door cover is de...

Abstract

The invention provides a novel explosion door structure which plays a role in pressure relief and prevents a main ventilator from being damaged due to impact of explosion airflow. Three or more springs are evenly arranged between a door cover and an upper cover, a novel explosion door with guide columns and guide sleeves is installed, the valve cover can be automatically in situ after being detonated under certain pressure, the valve cover can return to the original position after being detonated continuously, the valve cover continues to be pressed on an original sealing gasket, and a better sealing effect is achieved. The guide columns and the guide sleeves are not installed on stand columns, the guide columns and the guide sleeves are separated from the stand columns to return, the better guiding effect is achieved, and the service life is longer. A sealing strip adopts a structure that the lower part of the cross section is U-shaped and the upper part is triangular, and the valve body, the sealing strip 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. 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 a device for automatically opening and closing an explosion-proof door of 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, providing 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 opened and reset in time and accurately in order to prevent air backflow and the system’s secondary explosion. However, the current explosion-proof door structure swings left and right when resetting, the return position is not accurate, and the seal is not tight. The problem. Contents of the invention [0003] The invention provides a novel explosion-proof door structure, which can solve the technical problems of inaccurate return and poor sealing i...
