AI Technical Summary
The traditional storage tank ventilation hole structure cannot be regularly inspected and replaced, resulting in the metal wire mesh that may be blocked and the oil and gas in the tank cannot be discharged in time, which poses safety hazards.
The top of the storage tank is designed to open and close the ventilation device, including the ventilatory frame and the removable ventilation holes. The ventilation holes are composed of stainless steel wire mesh and pressure strips. It is fixed through the bolt nut, which is convenient for opening and disassembling.
The free opening and closing of the top storage pores of the storage tank has improved the maintenance and replacement convenience of the equipment, and the hidden safety hazards of the ventilators are blocked.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oil tanks, and more specifically, particularly relates to an openable and closable ventilation device on the top of a storage tank. Background Art
[0002] 9.7.1 of the national standard GB50341 requires that internal floating roof oil tanks without airtight requirements should be equipped with annular vents. The annular vents should be set on the tank wall or fixed roof above the design liquid level. The vents play a breathing role and provide sufficient ventilation conditions for the tank to prevent the oil and gas in the tank from reaching the explosion limit. It is a safe ventilation device; at the same time, it plays an overflow protection role in an accident state to ensure the integrity of the tank body and the fire safety of the oil storage area. There are two traditional vents, both of which are fixed structures. One is welded evenly on the top of the pipe wall along the circumference of the pipe wall on the upper part of the tank wall (maintenance or replacement of objects is basically impossible), and the other is welded at the opening of the tank top, and a metal wire mesh is welded at the ventilation point. The vent breathes for a long time, and the metal wire mesh may be blocked. This structure cannot be regularly inspected and replaced. Once the wire mesh is blocked, the oil and gas in the tank cannot be discharged in time, posing a safety hazard. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an openable and closable ventilation device on the top of a storage tank to solve the problems raised by the background technology.
[0004] The utility model of the tank top opening and closing ventilation device is achieved by the following specific technical means:
[0005] The tank top opening and closing ventilation device comprises a tank top and a vent frame; the characteristics are as follows: the tank top is rectangular, the vent frame is arranged above the tank top; a vent cover is arranged at the upper end of the vent frame; the vent cover comprises: a connecting hinge, a stainless steel wire mesh and a stainless steel wire mesh strip; one side of the vent cover is connected to the vent frame by a connecting hinge, a rectangular hole surrounded by the end of the vent cover away from the hinge is blocked by the stainless steel wire mesh, the periphery of the stainless steel wire mesh is pressed by the stainless steel wire mesh strip, and is fixed by bolts and nuts.
[0006] Furthermore, a plurality of rectangular holes are evenly arranged along the circumferential direction at the top edge of the storage tank, and ventilation hole frames are welded on the rectangular holes.
[0007] Furthermore, when the vent cover is closed, it is connected and fixed to the vent frame by means of a locking bolt and a locking nut.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] 1. In this device, the device is arranged at the edge of the tank top. The vent frame not only plays the role of reinforcing the tank top, but also can prevent rainwater from flowing into the tank along the opening. The vent cover can be opened by opening the locking bolt (so that the vent becomes a light-through hole). The vent is detachable. The utility model realizes the free opening and closing of the tank top vent, which improves the convenience of equipment maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS
