Embodiment Construction

[0036] Referring to the accompanying drawings, a sudden air unloading device 1 comprises a device 2 for controlling the flow of air between an inlet pipe 3 and an outlet pipe 5 connected to a container 4 for accumulating a certain volume of air.

[0037] To secure the container to the device, for example a flange 6 is mounted on the inlet of the device body.

[0038] A second flange 7 is generally also provided in order to connect the outlet pipe to a wall or to a pipe.

[0039] The control unit 2 generally consists of an obturator 2A resting on a base 2B, the obturator 2A being able to leave the base 2B to allow the free passage of air from the container 4 to an outlet duct 5 which may include a tube, the assembly as a whole is also called the output tube.

[0040] In the example shown, the main stopper 2A is in the shape of a piston or a possibly conical cup whose front face 2C bears against a seat 2B.

[0041] Thus, this front surface 2C lies on the convex surface of the ...

Abstract

The sudden air discharge device is placed between an inlet pipe (3) connected to a capacity accumulating a volume of air and an outlet pipe (5). The area (C) of the outlet pipe intake section at its distal end is greater than the area (A) of the inlet pipe intake at its end located near the flow control device.

Description

technical field [0001] The invention relates to a device for sudden unloading of air. Background technique [0002] In various applications, there is a need to eliminate the accumulation of materials detrimental to the proper functioning of the device. [0003] This is the case in cement plants or storage towers for heavy goods that are emptied by gravity. [0004] In order to do this, it is known to use an air sudden unloading device, rather than a purely mechanical device of the metal flapper type operated by a single person. [0005] These devices work by filling an air tank or container with a certain pressure and causing the air to be expelled suddenly to produce a burst. [0006] The accumulated material is dispersed under the action of the blast. [0007] The advantage of these units is that they operate automatically and can be located in places that are not easily accessible. [0008] The known device thus comprises a device for controlling the flow of the gaseo...
