Gravity type combined explosion door

Abstract

The invention relates to a gravity type combined explosion door which is characterized in that the gravity type combined explosion door comprises an upper limiting section, a middle limiting section and a lower limiting section, wherein the upper limiting section, the middle limiting section and the lower limiting section are arranged up and down in sequence; the upper limiting section, the middle limiting section and the lower limiting section are cylindrical, and adjacent limiting sections are connected through flanges; the bottom of the lower limiting section is arranged on the top of a powder storage tank through a flange, and a layer of film type explosion proof plate is arranged between the flange of the lower limiting section and the flange of the middle limiting section; a limiting device is welded outside the middle limiting section, one end of the limiting device, which is welded with the middle limiting section, is a horizontal section, and the other end of the limiting device is bent to extend upward and inclined to the upper part of the upper limiting section; an explosion door cover plate is arranged on the top of the upper limiting section, and one side of the explosion door cover plate, which is near the limiting device, is connected with the limiting device through a rotary arm mechanism; and a plurality of balancing weights are arranged on the explosion door cover plate. The gravity type combined explosion door has the advantage of simple and clever structure and can be widely used for explosion proof equipment such as the powder storage tank.

Description

technical field [0001] The invention relates to an explosion-proof door, in particular to a gravity combined explosion-proof door. Background technique [0002] At present, there are simple gravity type explosion-proof doors on the market, but they are not suitable for occasions with high protection requirements. Frequent opening and poor sealing effect. The second is that the current gravity type explosion-proof door has a relatively rough structure, and the rotating shaft is prone to jamming, so it cannot play a protective role. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a gravity-type combined explosion-proof door that can automatically close the explosion-proof door when the powder storage tank is relieved without jamming and has a good sealing effect. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a gravity-type combined explosion...
