Definitions

  • the invention also relates to a method for cleaning a tube, in which two similar brush assemblies are used, comprising, each, brushing means and a propellant, is introduced successively said brushing assemblies in the tube by a first end of the latter, so that the means of brushing cooperate with the inner periphery of the tube, the said brushing means and a step of brushing and progression of the brushing assemblies towards the second end of the tube alternately moving away and moving the brush sets together relative to each other and fluid is projected against said periphery internal of the tube.
  • the invention applies in particular to the cleaning of circular or substantially circular section (for example oval) and whose inner periphery can be striated.
  • the invention applies to cleaning of mouths whose inner periphery has streaks helical.
  • each propellant element comprises a jack and a wall flexible cylindrical.
  • the retraction of the cylinder piston deforms this wall, so that it bears on the inner periphery of the tube.
  • the device is thus moved into the tube by phase opposition the two jacks of the two thrusters and, moreover, by bringing these sets together and moving away alternately, by the control of a jack, which connects these two sets.
  • the device comprises three jacks, so that its price is high and that its actuation, requiring synchronized control of these three cylinders, is complicated.
  • a system for spraying a disinfection liquid on the duct wall to be cleaned may be provided.
  • this system of spray is connected via piping to a pump and a tank containing the spray fluid that are both outside duct.
  • the device of this document FR 2 491 785 is relatively complicated and does not seem to be suitable for cleaning striated tubes.
  • the present invention aims to improve the techniques to provide a simple and reliable device and process, which can be used and implemented easily, in particular for the cleaning of tubes with projection of a fluid (cleaning, lubrication, etc.).
  • the means for brushing a set brushing are able to rotate freely in relation to the means of brushing the other brushing set, so that each of the brushing means can clean helical striations formed in the inner periphery of said tube progressing each in the helix said streaks.
  • This ability of the brushing means to rotate freely compared to others is particularly interesting because it confers the device the ability to clean tubes whose inner periphery has striations arranged in a helix. Indeed, it allows the means brushing to guide you through the streaks to clean them perfectly.
  • the projection system is advantageously connected to the means for brushing a brushing assembly.
  • the reservoir has a filling orifice for filling said reservoir with fluid and said system for projection further comprises a fluid outlet comprising at least one nozzle distributed at the periphery of said support system for projecting said fluid against the inner periphery of the tube.
  • the reservoir is connected to at least one nozzle via a fluid outlet preferentially carried out in the system of support.
  • the projection system further comprises a fluid outlet for projecting said fluid against the inner periphery of the tube which comprises a plurality of nozzles distributed on the periphery of a support system, for example at one end of the latter.
  • the projection system may comprise a device specific rotation drive particularly advantageous when the brushing means are not rotatable.
  • the nozzles can be arranged on a ring which is free to turn relative to the brushing means under the effect of the pressure of the fluid.
  • the propulsive elements may, for example, include a plate (solid or recessed) able to be deformed perpendicular to its plane, that is to say in the axial direction of the tube, and / or an element brushing able to be deformed in the same direction.
  • this plate or this brushing element advantageously has globally the shape of a disc.
  • the two propulsion elements are made to cooperate with the said inner periphery being flexed axially towards the first end of the tube, said axially reciprocated and moved alternately brushing units relative to each other by feeding at least one control chamber connected to a fluid supply under pressure, said fluid is disposed in a reservoir which cooperates with said system of support and said fluid is pressurized using pressure existing in said control chamber.
  • the propelling element of this assembly flexes axially by adopting a curvature whose center is directed towards the entrance of the tube by which it was introduced.
  • he can adopt the shape of a corolla whose concavity is turned towards the entrance of the tube.
  • the element propeller of this second set brushing adopts the same form than that of the first set brushing and therefore has a curvature oriented in the same direction.
  • the tank is shipped with the cleaning system in the tube, so it should simply be filled at the beginning of the cleaning operations of a quantity of fluid adapted to the length of the tube to be cleaned so that it can guarantee a projection of fluid all along at least one complete passage of the brushing assemblies in the tube.
  • the projection of a fluid is advantageously made by rotary jets of so as to sprinkle the entire periphery of the tube.
  • the projection detergent oil makes it possible to remove all the dirt adhering to the inner periphery of the tube after the use of it. This is especially powder in the mouths fire or tallow in the garbage chute.
  • the periphery is advantageously wiped off tube of the tube with absorbent material disposed on each of the two brushing sets.
  • the absorbent material may be a fabric, a paper, cloth or the like, which is placed on each set brushing or possibly replacing each set brushing.
  • the means brushing a brushing assembly to rotate freely relative to brushing means of the other brushing assembly.
  • the device comprises a first support element on which is mounted one of the brush sets and a second support element on which is mounted the other brushing assembly, and means for slide said support members relative to each other in the axial direction, bringing them together and moving them alternately one the other.
  • the support system mentioned above therefore includes these two support elements and the means for sliding them one compared to each other.
  • the two support members may be two rods or a rod and a ring adapted to slide one on the other or two support plates connected by a retractable and stretchable rod.
  • the first and the second support element are respectively integral with a piston portion and a portion of cylinder of a cylinder.
  • the jack is a fluid cylinder under pressure and has a body provided with means for alternately connecting control chambers from the displacement of the piston portion to a fluid supply and a fluid outlet.
  • This jack can be controlled hydraulically or pneumatically, or by mechanical means such as a connecting rod or other means, these means being set in motion by a motor, for example an electric motor.
  • the device of FIG. 1 comprises two brushing assemblies analogous, respectively designated by references 10 and 20. They each comprise brushing means, respectively 12 and 22, as well as a propelling element respectively 14 and 24.
  • the device is for cleaning the inner periphery of a tube.
  • the axial direction D will be that of the geometric axis of this tube, that is to say that in which the device of the invention moves within the tube.
  • the brushing means therefore extend transversely to this axial direction D, and the bristles of the brushes are directed radially from so as to rub the inner periphery of the tube.
  • the elements thrusters 14 and 24 are also arranged transversely to the direction D.
  • the brushing means 12 or 22 comprise each several series of brushing discs arranged one to the other following others and having different brushing effects. So, we can provide a first 12A Nylon® brush, a second and a third brush 12B and 12C made of brass, and a fourth brush 12D in bronze.
  • the device of the invention is intended for cleaning tubes of circular or substantially circular section.
  • the tubes can also have a very slight taper.
  • the dimensions diameters D1 brushing means must be slightly greater than the inside diameter of the tube that the device is intended to clean.
  • the propellant elements 14 and 24 also have diametral dimensions D2 greater than the internal diametrical dimensions D T of the tube 1. They are at least equal to or slightly greater than the diametral dimensions D1. We also see in Figure 2 that, when the device is introduced into the tube, the propellant elements 14 and 24 are arched so as to have a concavity facing the inlet 1A of the tube.
  • the brush assemblies 10 and 20 are mounted so as to can be moved axially relative to each other alternatively in the sense of a ruzement and a distance.
  • assemblies 10 and 20 are similar, that is, they are chosen in such a way as to exercise substantially the same reaction efforts against the inner periphery tube 1 when introduced into the latter.
  • the resistance that the brushing assemblies oppose to their advancement in the direction F inside the tube is less than the resistance they oppose to their recoil in the G sense. This is due to the sense of their concavity. Because of the orientation of the edges of the propulsive elements, the forces of friction opposing a retreat are higher than those that oppose advancement. A decline would seek to reverse the concavity while the sense of concavity is of course preserved during a advancement.
  • propellants may be brushes relatively rigid. It has indeed been found that brushes having extremely thin hairs or low rigidity tend to twist at inside the tube after a first phase of advancement, placing substantially in a radial plane, in which case the concavity previously evoked tends to disappear. It is no longer possible to do advance the two sets brushing in the tube the way previously indicated.
  • propelling element a sufficiently rigid brush element, by example a brush whose hairs are sufficiently thick and dense to maintain the axial flexion that was imposed on them during their introduction into the tube. The skilled person may perform tests to determine the nature, diameter and density of suitable hairs.
  • the propelling element 14 or 24 may be a brush, similar to one brushes 12A to 12D previously mentioned and whose rigidity will be determined properly.
  • the choice to build the propulsion element in the form of a brush has the advantage of involving the latter in the cleaning of the tube or at least to prevent the contact of the outer periphery of the propellant with. the inner periphery of the tube does not cause the clogging streaks of the latter.
  • propellant elements 14 and 24 are disc-shaped plates, made of synthetic material such as elastomer, this material being chosen so as to have a relative stiffness or elasticity doing that once the propellant has been introduced into a tube and has a concavity turned towards the entrance of the latter, the concavity of this propellant element will be difficult to reverse inside the tube.
  • the brush assemblies 10 and 20 are mounted on a system of support so that the means of brushing a set brushing can rotate freely relative to the brushing means from the other brushing set.
  • the brushes are mounted on crowns whose inner periphery is cylindrical.
  • support elements 30, 40 or 35, 45 see FIG. cylindrical outer surfaces on which these crowns are arranged.
  • the two brushing assemblies 10 are analogous and in any case substantially the same resistance to advancement inside the tube.
  • brushing means 22 "soft" brushes relatively flexible, while harder brushes would be chosen for the brushing means 12.
  • the propelling elements 14 and 24 would be chosen in such a way as to present resistance to advancement such as the difference in resistance to advancement between the brushing means 12 and 22 is compensated if it is not negligible.
  • the brush assemblies 10 and 20 are respectively mounted on a first and a second support element, 30 and 40. These two support elements can slide relative to one another to be alternately close together and distant from each other.

  • Figures 6 and 7 show an alternative embodiment of the system gripper 42, which comprises a rod 42A and a ring 42B.
  • the brush assembly 20 is extended by the rod 42A whose end is equipped with ring 42B, which may also be in the form of a ball, which protrudes out of the second end 1B of the tube 1 when the brush assembly 20 reaches the vicinity of this end, which allows the gripping of the brushing assemblies 20 to be drawn or pushed back into the tube 1 without having to introduce the hands into the tube 1.
  • the device can be engaged in the tube by being manipulated by a handle 33 located at the end of the brush assembly 10 opposite to the brushing assembly 20. Once the device engaged in the tube, one can perform a step of brushing and progression of sets brushing towards the second end 1B of the tube as indicated previously.
  • the first brushing set (in this case the assembly 20) reaches the second end 1B of the tube.
  • the two brush sets 10 and 20 are extracted from tube and reintroduced into the latter by the second end 1B of such that the brushing means co-operate with the periphery inside the tube and that the two propulsion elements cooperate with this inner periphery being flexed axially towards the second end 1B of the tube.
  • the end portion 42 is accessible and sometimes the whole brushing 20 emerges from the tube or found in a room of larger diameter. Even if we continue movements of removal and approximation, the whole brushing 10 no longer progressing towards the exit because the brushing assembly 20 does not take more support on the inner periphery of the tube. To extract the device from the tube, it is therefore necessary to pull on the gripping end 42, by example using a rope.
