Definitions
- the invention relates to an accessory for a sudden air discharge device.
- the principle of these devices is to suddenly release a quantity of air so as to create a kind of deflagration which will suppress the heap of material which accumulates during the manufacturing process.
- such a device comprises a body housing a piston constituting a shutter disposed between a capacity and an outlet pipe.
- This outlet pipe is more or less long but, generally, for manufacturing and / or wear problems, this outlet pipe comprises a first part forming an integral part with the body of the discharge device and a second part or accessory intended to come and extend the first part.
- this second part makes it possible in particular to pass through the wall and to open out at more or less distance from the internal face of said wall.
- this second part or accessory also called a nozzle, has a constant surface section along its longitudinal axis, but often the geometry of this section is variable.
- the geometric shape of the entry of this accessory is circular while the exit geometry is, possibly, flattened in order to be able to occupy the place of one or more refractory bricks.
- the volume of the capacity is limited due to the size of the latter and, very often, the air supply pressure of these capacities is limited.
- the subject of the invention is an accessory intended to be mounted on the end of an outlet pipe of an abrupt air discharge device, this accessory being in the form of a tube mounted coaxially to the axis of the outlet pipe, this accessory being characterized in that the cross-sectional area of this tube decreases in the direction of the exhaust of the air and then increases, thus forming a convergent then divergent section.
- the invention also relates to the sudden discharge device equipped with the accessory according to the invention.
- the discharge device is mounted, for example, on a wall 9.
- This sudden discharge device comprises a body 1A or envelope containing a shutter 3 and its seat 3 A, which shutter, when it is moved away from its seat, allows the passage of the air contained in the capacity to an outlet pipe 4.
- This short outlet pipe is extended by an accessory 5 in the form of a tube mounted coaxial with the axis of the outlet pipe 4.
- This accessory is fixed to the end of the outlet pipe, by a fixing means 10 such as a flange.
- This accessory 5 is generally fixed in a wall 9 which it passes through.
- the cross-sectional area of this tube decreases in the direction F of the exhaust of the air and then increases, thus forming a convergent section A then divergent B.
- the area E of the entry of the accessory will be equal to the area S of exit.
- the area S of the outlet of the accessory will be greater than this area E of entry.
- the ratio between the section D taken at the level of the section having the smallest area and the inlet section E will be greater than or equal to 1/5 but preferably greater than 1/3.
- the ratio between section D taken at the section with the smallest area and the outlet section S will be greater than or equal to 1/5.
- the distance between the position of the aforementioned section D and the seat on which the shutter rests will be at most one meter for a pressure up to twelve bars.
- Tests have been carried out with an abrupt air discharge device with an inlet diameter E of 150 mm with a capacity of 100 liters.
- the force sensor is placed at the end of a 500 mm long tube.
