Definitions
- the invention relates to a device for firing a flowable medium, in particular a hardening building material, with the features of the preamble of claim 1.
- a cartridge for expelling liquids under pressure is known from DE 35 45 737 C1.
- This cartridge has a liquid and a propellant charge chamber, which are separated from one another by an expulsion piston.
- the expulsion piston encloses a cavity and its end face directed towards the liquid column has one or more predetermined breaking points. These predetermined breaking points cause the central axial part of the end face to be separated from the remaining part of the end face as soon as the expulsion piston strikes its conical end after the propellant charge has ignited and passed through the liquid chamber.
- This part of the expulsion piston which remains after breaking has the shape of a ring or a tube.
- a disadvantage of these known devices is the unfavorable firing signature, ie that after the liquid has escaped due to the explosively expanding propellant gases, high noise emissions (muzzle blast) and the muzzle flash occur.
- the invention is therefore based on the object of creating a device for firing or pulse-like acceleration of a flowable medium, such as liquids, solutions, emulsions and suspensions, in particular a hardening building material, which is essential in comparison with known devices ⁇ Lich has lower noise emissions and the muzzle flash is practically completely suppressed.
- a flowable medium such as liquids, solutions, emulsions and suspensions, in particular a hardening building material
- the invention therefore offers the advantage that such devices can be used in areas which require compliance with certain noise protection regulations. In addition, a reduction in the dangers for operators and other persons in the area of such a device is achieved.
- a nozzle is arranged on the pipe mouth, which serves at the same time as a collecting device for the expulsion piston.
- the nozzle can have an area widening into the interior of the tube, and the expulsion piston can be designed to be deformable in such a way that that after the liquid has been expelled, it rests against the inner wall of this area and essentially seals the nozzle opening in this way.
- the expulsion piston is preferably made of a deformable material with a low specific weight in order to keep the impact forces that occur when the piston is caught low.
- metallic materials such as aluminum or brass, corresponding metal alloys, composite materials based on plastics and reinforcing fibers can be used.
- Thermoplastic materials such as polytetrafluoroethylene (PTFE) or polyethylene (PE) are preferably used.
- the expulsion piston and / or the inner wall of the mouth region of the tube and / or the nozzle have grooves which are oriented and dimensioned such that they enable the propellant gases to escape slowly after the nozzle opening has been sealed, without that this would involve a substantial noise emission.
- the expulsion piston can also be provided with at least one opening which is closed by a predetermined breaking point, the predetermined breaking point being broken up by the deformation when the expelling piston is caught in the nozzle, thereby ensuring a slow escape of the propellant gases without substantial noise emission.
- the propellant charge is in the form of a cartridge, the expulsion piston being detachably connected to the cartridge.
- the medium to be fired can take place either before the cartridge is inserted or by means of a suitable feed device after it has been inserted into the tube of the device.
- a multiple nozzle body with at least two nozzles can be arranged, the nozzle block being displaced relative to the pipe after each shot in such a way that after moving a free nozzle, which is not closed by a deformed expelling piston, is located at the pipe mouth.
- the nozzle block can be designed to be movable in the direction of the tube axis by means of a first holding and adjusting device and in a direction transverse to the tube axis by means of a second adjusting device.
- a further device for cleaning the nozzle and / or ejecting expulsion pistons located in the nozzles can be present. This ensures that several shots in rapid succession are possible by means of the device according to the invention.
- Figure 1 is a schematic representation of the device according to the invention for firing a flowable medium and its use for soil consolidation.
- FIG. 2 detailed drawings of the front region of the tube of the device in Fig. 1;
- Fig. 3 shows a further embodiment of the invention with a multiple nozzle body and Fig. 4 shows an expulsion piston in section or in plan view.
- Fig. 1 shows a device 1 according to the invention for firing a flowable medium, which in special use as a cannon for injecting a hardenable building material, e.g. Liquid plastic or cement milk, in which loose rock 2 to be solidified is formed.
- a hardenable building material e.g. Liquid plastic or cement milk
- the device 1 can be raised and lowered via a suspension 3 and can be directed at any angle to the surface of the loose rock 2 to be consolidated.
- the device 1 drives out injection material under high pressure in the form of a highly concentrated jet.
- the latter penetrates the loose rock 2 over a corresponding length in the predetermined direction.
- individual shots or series of shots can be provided.
- the loose rock 2 of the terrain jump shown in FIG. 1 is solidified by the tensile strands 4, the strands acting as reinforcement of the terrain jump.
- the device according to the invention can also be used, for example, in such a way that instead of directly injecting hardening building material, the holes required for consolidation are first shot into the ground or the Loker rock 2 and the holes are then fired with hardening building material.
- the holes are produced by injecting a concentrated high-pressure water jet using the device according to the invention.
- FIG. 2a shows a front section of the tube 5 of the injection cannon 1 in FIG. 1.
- a nozzle 6 which can be detachably connected to the tube 5 by means of a suitable quick fastener.
- the diameter of the outlet opening 7 of the nozzle 6 is selected such that a high-speed jet 8 (FIG. 2b) with the desired ratios of pressure, speed and diameter results depending on the pressure and the viscosity of the flowable medium to be expelled.
- the nozzle opening 7 is adjoined by a region 9, which preferably widens like a truncated cone, which on the one hand brings about an improvement in the flow of the medium to be expelled and on the other hand fulfills the function of a collecting device described below.
- a predetermined amount of the medium 10 to be fired for example liquid plastic, cement milk or water, is introduced into a front region of the tube 5 of the device according to the invention shown in FIG.
- a cartridge filled with the medium in question can also be inserted into the front region of the tube 5. This has the advantage that leakage of the medium when the tube is in a downwardly inclined working position and contamination of the tube inner wall is largely avoided.
- a propellant charge cartridge 11 which has an expulsion piston 12, is inserted into the front area of the tube 5, which is filled with the flowable medium 10, and has an expulsion piston 12, which is in the front area of a propellant charge 13 filled sleeve 14 is inserted.
- the diameter of the expulsion piston 12 corresponds approximately to the inside diameter of the tube 5, so that the expulsion piston 12 seals the front region of the tube 5 filled with the flowable medium 10, but is nevertheless kept axially displaceable in the interior of the tube for expelling the medium.
- the expulsion piston 12 shown in FIG. 2 is essentially cylindrical.
- an initially cylindrical, but conically tapering cavity 15 is formed in the front area, whereby an improved seal with respect to the medium 10 is achieved when the tube 5 is passed through.
- the improved sealing results from the forces which act through the pressure of the propellant gases 19 after the propellant charge has been ignited in the radial direction on the thin, hollow cylindrical wall 16 of the expulsion piston 12, so that the wall 16 is pressed against the inner wall of the tube 5.
- the formation of the cavity 15 in the expulsion piston 12 results in both a weight saving and a secondary volume which suppresses or weakens the peak pressure which arises when the propellant charge 13 burns up.
- the expulsion piston 12 is preferably made of a thermoplastic, for example PTFE (Teflon).
- the expulsion piston 12 shown in FIG. 2 has one or more axial recesses or blind holes 17, so that the remaining thin wall 18 acts as a predetermined breaking point when the expulsion piston 12 is deformed when it is caught by the nozzle 6.
- FIG. 4 shows in longitudinal section (FIG. 4a) and in plan view (FIG. 4b) a preferred expulsion piston 12, the end face of which is turned towards the nozzle 6 (see FIG. 2) is rounded.
- a blind hole 17 is arranged in the tip, thereby creating a thin wall 18 which acts as a predetermined breaking point when the expulsion piston 12 is deformed. Opening the predetermined breaking point enables the propellant gases to escape slowly.
- longitudinal grooves 27 (FIG. 4) can also be arranged on the outer surface of the expulsion piston 12. This Grooves 27 also cause the propellant gases to escape slowly when it is in contact with the nozzle.
- the mode of operation of the device according to the invention is described below with reference to FIGS. 2a to 2c.
- the propellant charge 13 is ignited by means of a known igniter, not shown in detail.
- the expulsion piston 12 is released from the front region of the sleeve 14 of the propellant charge cartridge 11 and moved axially in the direction of the nozzle 6, as a result of which the medium 10 exits the nozzle opening 7 under high pressure in the form of a high-speed jet 8 - Is driven (Fig. 2b).
- the expelling piston 12 After the medium 10 has been completely expelled, the expelling piston 12 is in the position shown in FIG. 2c. As can be seen from FIG. 2c, the expulsion piston 12 is caught under the pressure of the propellant gases 19 by the region 9 of the nozzle 6 which widens in the direction of the inner tube 6, the expulsion piston 12 suffering a deformation. As a result, the nozzle opening 7 is essentially sealed, so that the explosive expansion of the propellant gases 19 after the medium 10 has been completely expelled from the pipe 5 and the muzzle blast associated therewith and the muzzle flash also associated therewith are practically completely suppressed.
- the expulsion piston 12 is designed by a suitable choice of its shape and the material such that it substantially completely closes the nozzle opening 7 after expelling the medium 10 without, for example, breaking.
- the expulsion piston 12 is designed by a suitable choice of its shape and the material such that it substantially completely closes the nozzle opening 7 after expelling the medium 10 without, for example, breaking.
- the predetermined breaking point 18 of the expulsion piston 12 is opened by the deformation that occurs, so that a slow reduction in the propellant gas pressure without significant sound emission into the area 20 in front of the nozzle opening 7 is ensured is.
- the expelling piston can of course also have one or more non-axially extending recesses or predetermined breaking points or be provided on its outer surface with grooves 27, which after collection of the expulsion piston 12 through the region 9 of the nozzle 6 enable the propellant gases to escape slowly.
- These grooves 27 should preferably also be sealed with a predetermined breaking point from the inner wall of the tube in order to ensure that the medium is completely expelled.
- the area 9 of the nozzle 6 and possibly the foremost area of the inner wall of the tube 5 can have grooves which serve the same purpose.
- the expulsion piston 12 can either be introduced into the tube 5 completely separately from the propellant charge cartridge 11 or be connected to the rear region of a cartridge receiving the medium 10, the diameter of the expulsion piston being selected in a suitable manner in each case.
- a single cartridge can also be used, which contains both the propellant charge powder and the medium to be fired as well as the expulsion piston.
- the nozzle can also be integrated into the cartridge, so that cleaning of the nozzle arranged at the pipe mouth is not necessary.
- a multiple nozzle body 21 is used, in which a plurality of identical or also different nozzles are formed.
- the multiple nozzle body 21 is held adjustable by a holding and adjusting device 30 relative to the mouth of the tube 5.
- the multiple nozzle body 21 can be moved forwards by means of, for example, hydraulically actuated adjusting rods 22 parallel to the tube axis until the front end of the tube 5 is completely released by the relevant nozzle 6 'with its opening 24.
- the multiple nozzle body 21 can be displaced in a plane perpendicular to the pipe axis by means of a further, for example hydraulically actuated adjusting device 25, until a further nozzle 6 'not clogged by a deformed expelling piston 12 in front of the mouth of the pipe 5 is positioned.
- the multiple nozzle body 21 is slidably held in holding elements 23 connected to the adjusting rods 22.
- the multiple nozzle body 21 is then moved in the direction of the mouth of the tube 5 by the holding and adjusting device 30 until the tube 5 is in intimate engagement with the opening 24 of the relevant nozzle 6 '. After reloading, the next shot can be fired immediately.
- the nozzle body 21 can also each have a plurality of differently designed nozzles 6, with nozzles of the same type being arranged, for example, on a vertical line and different nozzles on a horizontal line in the form of a matrix.
- a further adjustment device not shown, would be required, which moves the multiple nozzle body 21 in its plane perpendicular to the adjustment direction of the adjustment device 25. It is thereby achieved that the most varied flowable media or the firing of one and the same medium can be carried out with different characteristic values of the high-speed jet with a single multiple nozzle body.
- the rapid succession of shots with the same medium and the same high-speed jet is ensured by the existence of several nozzles of the same type.
- the multiple nozzle body 21 and the devices for adjusting it can also be used with other devices for firing a flowable medium, e.g. can also be used in conjunction with known devices.
- a cleaning device 26 is indicated in FIG. 3, which, after the multiple nozzle body has been moved, ejects the deformed expelling piston 12 located in the relevant nozzle 6 'from the previous shot.
- the cleaning device 26 can have a mandrel, the outer diameter of which essentially corresponds to the inner diameter of the nozzle opening 7 ′′.
