Embodiment Construction

[0020] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the shape of the pressure relief fire barrier layer of the flameless pressure relief device is a fan-shaped structure with a central angle greater than 90 degrees and less than 180 degrees, with a large pressure relief area and high pressure relief efficiency; the explosion vent plate 1 is installed at the entrance of the explosion vent shell 2 The inlet of the explosion venting shell 2 is connected to the pipeline; the fire retardant and pressure relief layer 4 is installed at the outlet of the explosion venting shell, and whether there is dust accumulation in the explosion venting shell can be observed through the window 3. When an explosion occurs, the explosion venting plate 1 ruptures under the action of the shock wave and...

Abstract

The invention relates to a flameless pressure relief device. The flameless pressure relief device comprises an explosion venting plate and an explosion venting shell, wherein the outlet of the explosion venting shell is equipped with a fire-retarding layer which is of a multi-layer type structure; the mesh number of the outer layer of the fire-retarding layer is greater than that of the inner layer of the fire-retarding layer; a middle layer is arranged between the inner layer and the outer layer; the middle layer is a metal net layer which is formed by superposing and spreading single metal net layer by layer; netting wires between upper and lower layers of the metal net are crossed in a different-surface oblique-angle mode or are formed by arranging a plurality of metal rings in a multi-layer mode; metal wires of the fire-retarding layer are formed by knitting in a hooked needle mode; and the structure of each metal ring comprises a circular ring foil and a crossed blade, wherein thecrossed blade and the circular ring foil are connected at an oblique angle. The flameless pressure relief device disclosed by the invention can effectively gather dust and can prevent flame from spreading in addition to having the advantages of being great in pressure relief area and high in pressure relief efficiency, so that man-machine safety is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, in particular to a flameless pressure relief device. Background technique [0002] The flameless pressure relief device is mainly used in the wood processing industry, metal product processing industry, and other industries that generate dust. Specifically, it is mainly used on the pipelines connecting cyclone separators, dust collectors and other dust removal devices with other equipment. [0003] On July 19, 2017, a patent with application number 201720880740.8 was disclosed. This patent relates to a high flow rate anti-flame overflow flameless relief device, which includes an explosion venting plate and an explosion venting cavity. The explosion venting cavity is provided with an inlet and an outlet, and the explosion venting plate is connected to the explosion venting cavity. On the inlet, a fire-resistant layer is installed at the outlet of the explosion-venting cavity, and the fire...
