specific Embodiment approach 1

[0026] Specific embodiment one: combination Figure 1 to Figure 8 To illustrate this embodiment, an explosion-proof device for oilfield oily sludge treatment equipment in this embodiment includes a valve body 1, a valve plate 2, a baffle bottom plate 7, a rubber plate 9, a sealing ring bottom plate 10, a sealing ring 11, and a second A rotating shaft 12, a second rotating shaft 16, two valve arms 3, a plurality of baffle guide shafts 5 and a plurality of springs 6;

[0027] The valve body 1 includes a valve seat 1-1, two flanges 1-2, a first connecting plate 1-3 and two second connecting plates 1-4;

[0028] The valve seat 1-1 is a hollow cylindrical valve seat. The upper and lower ends of the valve seat 1-1 are respectively fixedly connected to a flange 1-2, and the lower ends of the two second connecting plates 1-4 are connected to the side of the valve seat 1-1. The walls are fixedly connected, the two second connecting plates 1-4 are arranged vertically, and the two second con...

specific Embodiment approach 2

[0034] Specific implementation manner two: combination figure 1 The present embodiment will be described. The valve plate 2 of the present embodiment rotates around the second rotating shaft 12 as an axis. With this arrangement, when the pressure in the pyrolysis furnace increases sharply, the valve plate 2 can automatically open to release the pressure, and automatically reset under the action of gravity after the pressure is released, thereby avoiding explosion hazard. The other composition and connection relationship are the same as in the first embodiment.

specific Embodiment approach 3

[0035] Specific implementation mode three: combination figure 2 To describe this embodiment, the rotation angle of the valve plate 2 of this embodiment is A, and A=0°-60°. Other components and connection relationships are the same as those in the first or second embodiment.

Abstract

The invention provides an explosion-proof device of oil field oily sludge treatment equipment and relates to the technical field of safety protection of the oil field oily sludge treatment equipment. The explosion-proof device is provided for solving the problems that an existing explosion-proof device is small in release aperture, long in pressure relief time and low in speed, is likely to be damaged in the pressure relief process, cannot automatically reset after pressure relief and affects continuous production. A valve plate of the explosion-proof device is connected with a valve body through a first rotary shaft. The valve plate presses a seal ring on the valve body tightly through self-weight to realize sealing. The valve plate rotates with the first rotary shaft as the circle center. When the pressure in a valve exceeds the self-weight of the valve plate, the valve plate is bounced up. The bounced scope of the valve plate is controlled through a plurality of springs and a rubber plate on the upper portion of the valve body. The bounced inertia of the valve plate is subjected to buffering and pressure releasing. The valve plate is bounced to the highest point and then is reset under the action of self-weight. The explosion-proof device is applied to a pyrolyzing furnace of the oily sludge treatment equipment.

Description

Technical field [0001] The invention relates to the technical field of safety protection of oilfield oily sludge treatment equipment, in particular to an explosion-proof device for oilfield oily sludge treatment equipment. Background technique [0002] As a special safety valve, the explosion-proof valve discharges the pressure generated during the explosion of the explosive gas. It is an impact dynamic pressure, which has the advantages of short time and fast attenuation. The structure of the explosion-proof valve is different in different places of use. The pyrolysis furnace of oily sludge treatment equipment produces flammable and explosive substances during the working process. Flammable and explosive substances include non-condensable gas, oil vapor, and combustible dust. These flammable and explosive substances have an explosion hazard and affect pyrolysis The problem of furnace work safety. [0003] Existing explosion-proof devices have the problems of small relief caliber...
