Definitions

  • the present invention relates to a device for blasting dry ice, in particular dry ice (see for example WO 90/09243 A1 ). It will find its applications, in particular, in the field of cleaning surfaces, especially large surfaces such as vehicle body parts. This example is not, however, limiting and the invention will also find its applications, in particular, for cleaning parts of smaller sizes. Dry ice blasting is effective in the combination of different effects, a mechanical effect due to the kinetic energy of the ice particles, a thermal effect due to the temperature of the particles and a blast effect due to the sublimation of the ice in contact with the surface to be cleaned. It also has the advantage of not leaving residues. Indeed, after sublimation, the dry ice, transformed into gas, evacuates itself.
  • the nozzles have a large length allowing the realization of a stream of particles centered in the middle of the fluid jet engine. This has the advantage of particularly efficient cleaning by concentrating the impact zone of the particles but has disadvantages.
  • these different devices are highly consumer in motor fluid. They are also difficult to handle.
  • their dry ice jet has an impact surface of limited dimensions.
  • the invention aims to solve all or part of the following problems and proposes for this purpose a device for spraying dry ice particles according to claim 1.
  • said divergent has at least a first stage extending between the neck and an outlet orifice of said first stage, the ratio between the surface of the neck and the surface of said outlet orifice of the first stage of the divergent being greater than 0.2, in particular greater than 0.5, in particular greater than 0.73. Said ratio will, for example, be less than 0.9.
  • a nozzle makes it possible to limit the consumption of carrier fluid while obtaining very good cleaning results, especially in terms of eliminating greasiness present on the objects. to clean.
  • the invention will more generally find its applications for the cleaning of fine pollution, thickness less than 3 mm, among others. It also allows the use of nozzles of limited size, including the nozzles having divergents whose length between the neck and the outlet orifice of the nozzle is less than 50 mm.
  • section is used in the following to mean the section of the nozzle in a plane orthogonal to its direction of longitudinal extension, that is to say, the principal direction in which the nozzle leads. the fluid that passes through it.
  • angle of divergence will have the following meaning in the following.
  • the angle at the apex of the cone bearing the truncated cone forming the or each of the stages of the divergent is the angle at the apex of the cone bearing the truncated cone forming the or each of the stages of the divergent.
  • the divergent device has a single stage, said stage being provided with a divergence angle ⁇ of the order of 6 °. This gives a high cleaning efficiency.
  • said divergent has a single stage, said stage being provided with a divergence angle ⁇ greater than 7 °, in particular greater than 15 °. A flared jet is then obtained with an enlarged impact surface.
  • the divergent has a second stage, said first stage having a divergence angle of the order of 6 ° and the second stage a divergence angle greater than 7 °, in particular greater than 15 °.
  • a particle acceleration effect favorable to cleaning efficiency is then combined with a broadening effect of the impact zone of the particles.
  • said neck is a sonic neck.
  • the nozzle may have a convergent provided upstream of the neck in the direction of flow of the driving fluid, charged with said particles, and wherein the convergent and the divergent are connected directly to one another at the neck.
  • the invention also relates to a nozzle of a projection device as described above.
  • the invention relates to a device for blasting dry ice particles, for example dry ice, in particular for cleaning surfaces.
  • Said device comprises a gun 10 provided, in particular, with a supply 1 of driving fluid, a supply 2 of liquid carbon dioxide and a chamber 3 for the formation of dry ice particles. It also comprises a nozzle 4, connected to the gun 10, projecting, under the action of the driving fluid, the particles formed in the chamber.
  • Said driving fluid thus enters the device through the supply 1 of the driving fluid and then charges the ice particles generated in the chamber 3, to the exhaust of said chamber.
  • This forms a flow of motor fluid and ice particles that passes through the nozzle 4 to be projected on the part to be cleaned.
  • the nozzle 4 allows the passage of the motor fluid, the latter driving said particles.
  • Said driving fluid is, for example, compressed air.
  • said nozzle 4 has an outlet orifice 5 and comprises a neck 6 and a divergent 7. Said divergent 7 extends between the neck 6 and the outlet orifice 5 of the nozzle.
  • Said nozzle 4 further comprises here a convergent 8, placed upstream of the neck 6 in the flow direction of flow. It may also have a connection 9 to the gun 10. Said connector 9 is optionally provided with a fixing ring 10 provided at a threaded portion of said connector 10.

It is, in particular a width h configured at the size of the formed particles. It will thus be possible to use a width h less than 2 mm, for example of the order of 1.2 or 1.3 mm.
  • the neck 6 here has a rectangular section, one of the dimensions of which corresponds to the width h of the diverging portion 7.
  • Said divergent has also a divergence angle ⁇ greater than 7 °, to obtain an enlargement of the nozzle outlet flow. This is an angle of about 45 °. Alternatively, it could be an angle of about 6 ° to maintain a substantially straight stream nozzle outlet.
  • said divergent portion 7 may have a length L of said nozzle 4, measured between the neck 6 and the outlet orifice 5 of said nozzle 4, a length 1 S of the divergent section at said outlet 5 of the nozzle and an angle of divergence ⁇ according to the following law: 0.05 ⁇ I S / tan ⁇ ⁇ The ⁇ 0.4 ⁇ I S / tan ⁇ .

  • Said first stage 20 has a divergence angle of the order of 6 ° and the second stage 21 has an angle of divergence greater than 7 °, for example between 30 and 60 °, here about 45 °.
  • the first stage 20 allows an acceleration of the particles with a minimum motor fluid consumption while the second allows the widening of the flow, this by limiting the overconsumption of the driving fluid, the particles enjoying the kinetic energy acquired in the first floor.
  • Each of the stages here is of rectangular section, of the type of the embodiment of the figures 2 that is to say, with constant width h and length l linearly increasing.
  • the values of the width h may also be identical to that of the embodiment of the figures 2 . They are identical from one floor to another.

  • the outlet orifice 5 of the nozzle may again be in the form of a slot. This may have a height of less than 2 mm, in particular of the order of 1.2 or 1.3 mm and / or a length of between 40 and 60 mm.
