Problems solved by technology

The mandated adoption of dust collectors has correspondingly increased the risk of explosion inherent in the provision of such dust collecting equipment.
The need for explosion protection with improved dust collection equipment is exacerbated by the fact that the dust collectors tend to be less rigidly constructed and not as able to withstand internal explosions than was once the case.
In addition, in those applications where the required protective burst pressure is so low that

Embodiment Construction

[0033] The principal, although not exclusive, utility for the rigid, integrated, one-piece overpressure vent panel assembly hereof is in explosion protection applications. To that end, the unitary overpressure vent panel assembly 10 as shown in the drawings is illustrated in operative position in a typical installation such as the upright side wall 14 of a particulates collector in the nature of a bag house 12 having an inlet 16 and an outlet 18. Bag house 12 conventionally is provided with a plurality of filters which for example may be loosely woven fabric bags mounted over respective outlet conduits which communicate with the interior of structure 12.

[0034] It is to be understood that mounting of unitary overpressure vent panel assembly 10 on the side wall 14 of bag house 12 is for illustrative purposes only and the assembly 10 may be positioned in any one of a number of strategically determined locations depending upon the type of confined zone to be protected from an explosion,...

Abstract

Unitary one-piece frameless overpressure vent panel assembly (10) includes a rigid, generally planar primary support member having a central relief opening (26), a rigid, generally planar secondary support member (44) provided with a central relief aperture (46), and a frangible vent panel (30) between the support members in full closing relationship to the relief opening and the aperture. A sealant element (48) may be provided between the vent panel and at least one of the support members in circumscribing relationship to the relief opening or aperture. At least one line of weakness (34) may be provided in the vent panel. A flexible gasket (58) secured to the secondary support member assures a fluid tight seal between the vent panel assembly and the structure defining a protected zone. Alternatively, a knife blade or the like may be provided adjacent the vent panel to effect severing thereof under a predetermined overpressure in lieu of a line of weakness in the panel.

Description

[0001] 1. Field of the Invention[0002] This invention relates to a unitary, one-piece, integrated, non-fragmenting overpressure vent panel assembly that may be installed in covering relationship to the pressure relief area of a combined zone to be protected from the buildup of uncontrolled overpressures, and to then be removed as a unit for replacement with a similar vent panel assembly after actuation thereof. The vent panel assembly is especially useful for instantaneously venting dangerously high internal pressures which result from an explosion in a manner to preclude catastrophic buildup of pressures within a confined area that is normally exposed to relatively low operating pressures. The vent panel assembly has utility for use in protecting equipment such as bag house dust collectors, cyclones, conveyors, bucket elevators, dryers, vacuum receivers, electrostatic precipitators, silos, storage bins, large pipes, and ducting.[0003] 2. Description of the Prior Art[0004] Burst mem...
