Definitions
- the invention relates to a device for producing a gas-liquid mixture, in particular an air-water mixture, in the region of at least one cutting head or cutting roller arranged rotatably on a cantilever arm of a cutting machine, in particular chisels, comprising at least one pair of nozzles a nozzle for ejecting a gas jet and a nozzle for ejecting a liquid jet, the axes of the nozzles of a pair of nozzles being aligned such that the jets meet at a distance from the nozzle outlet openings.
- Devices of the type mentioned above can be found, for example, in DE 19951848 AI.
- a number of devices are also known in which cooling water or water-air mixtures are introduced into the cutting track of cutting machines, so that sparks can be extinguished and the cutting track can be cooled behind the cutting tool.
- Such spraying with air and / or water is known, for example, in the form of a single chisel spray, in which the release of the nozzle is controlled as a function of a displacement movement of a chisel as a result of the reaction force.
- devices have been proposed for forming a more or less uniform spray with which the spray jets are directed onto the cutting unit in order to generate a spray around the cutting unit.
- such a device is known from DE 3609754 AI.
- Spraying devices for chisels of cutting heads serve primarily the purpose of dust control and to reduce the risk of ignition of an emerging methane-gas-air mixture. By cooling the chisels, wear should naturally also be reduced.
- the spraying is often carried out with a gas-liquid mixture and in particular with an air-water mixture, various methods having become known to produce such an air-water mixture.
- a spray of spray is produced from air and water by atomization, which is used to act on the cutting bits and / or the cutting tracks in order to prevent flames from occurring in the area of the cutting space.
- DE 2816797 AI it is proposed to produce an air-water mixture that radial bores are provided in the air outlet channels, which are connected to a water-carrying space, so that water and air emerge atomized from the nozzles.
- the axes of these nozzles are directed against the side of the cutting head on which the chisels emerge from the rock.
- a spraying system has become known from DE 19851620 AI, in which the atomizer nozzles are designed as mist nozzles, in the nozzle bores of which are connected to the air chamber to which compressed air is applied, a water injection nozzle which is pressurized with water and which produces a water jet running in the longitudinal direction of the nozzle bore opens. the pressure of the pressurized water is higher than that of the compressed air.
- At least one water jet generating a water jet is assigned to an air nozzle in such a way that the air jet and water jet come into contact at a distance from the nozzle outlet openings, forming an air-water mixture which acts on the cutting head come.
- the individual nozzles are arranged in such a way and the axes of the nozzles are aligned such that the air and water jets meet at an angle of approximately 10 to 15 °.
- the known nozzle systems have in common that a not inconsiderable amount of water has to be used to produce a water-air mixture, which has the disadvantage that the sole can soften, which means that the safe and precise movability of a cutting or stretching machine is not more is guaranteed.
- the invention is therefore aimed at from creating a device for generating a gas-liquid mixture of the type mentioned at the outset, with which efficient atomization in the area of the cutting units can be achieved even when small amounts of liquid are used, so that the sole is not softened inadmissibly.
- the liquid should be atomized as finely as possible in order to reduce the risk of ignition in the area of the cutting unit.
- the device according to the invention based on the spraying device mentioned at the outset, essentially consists in the axes of the nozzles of a pair of nozzles enclosing an angle of between 45 and 135 °, preferably between 75 and 85 °.
- liquid and gas nozzles are oriented differently from the known devices in such a way that a liquid and a gas jet meet at an angle of between 45 and 135 °, a particularly effective atomization is achieved, whereby a mist with a droplet spectrum arises , which favors a reduction in the risk of ignition while at the same time ensuring adequate cooling of the cutting units.
- the steeper angle of attack between the gas and liquid nozzle leads to a greater deflection of the water jet from its original direction, which ensures more efficient atomization. It has been shown here that there is a substantial improvement in atomization at angles greater than 45 °, since here the normal component of one jet is greater than the parallel directional component relative to the other.
- the atomization performance can be further improved by the fact that the liquid jet hits the gas jet very close to its mouth, since the air speed is highest there and particularly high shear forces can act.
- the device according to the invention is therefore preferably further developed such that the crossing point of the axes of the Nozzles of a pair of nozzles is less than 100 mm, preferably less than 50 mm, particularly preferably about 8 mm, from the nozzle outlet opening of the gas nozzle.
- the axes of the nozzles of a pair of nozzles enclose an angle of between 45 and 135 ° with each other, there is naturally a risk that the liquid jet will pierce the gas jet.
- the outlet angle of the liquid nozzles is between 5 and 10 °, the liquid nozzles being able to be designed as round jet nozzles, the outlet openings of which preferably have a diameter of approximately 1 mm.
- an optimization can be carried out in such a way that the diameter of the outlet openings of the gas nozzles is at least 3 mm, preferably approximately 5 mm, and furthermore the gas nozzles can be designed with a swirl chamber upstream of the outlet opening to form turbulent flows. Turbulence can form in such a swirl chamber upstream of the outlet opening, so that the gas jet emerges from the nozzle as a turbulent flow or with a swirl. This can further increase the efficiency of the atomization and further reduce the droplet diameter of the mist.
- the individual parameters of the mist that forms can be influenced by setting the gas supply pressure or liquid supply pressure, whereby particularly favorable properties can be observed when the gas supply pressure is set from 0.6 to 1.5 bar.
- the training is further developed such that the Gas nozzle for ⁇ a gas feed pressure of 0.6 bar to 1.5 bar, and the liquid nozzles are formed for a liquid supply pressure of 4 bar up to 5 bar.
- an extremely fine mist is formed in the area of the cutting tools, which, in addition to reducing the risk of ignition, also cools the tools.
- the nozzles are arranged on the side of the cutting head on which the chisels enter the rock.
- the air-water mixture is effectively guided through the cutting area due to the Cuanda effect, so that the cooling effect is present in the contact zone and largely also outside of the intervention.
- the design is advantageously developed in such a way that the axes of the gas nozzles are directed towards the cutting tools, in particular the tip of the chisels.
- the mist is formed with a flow directed towards the tips of the chisels, so that a targeted action on the parts of the cutting unit which are exposed to a particular load is ensured, and sufficient cooling is achieved despite a reduction in the amount of coolant.
- a plurality of nozzle pairs is preferably arranged on a nozzle block connected to the cutting arm and running parallel to the axis of rotation of the cutting head or cutting roller.
- the distance between adjacent nozzle pairs is advantageously less than 150 mm.
- the design is advantageously developed in such a way that the nozzles are pivotally mounted in the nozzle assembly ,
- the spraying device With the spraying device according to the invention, it is possible to achieve a substantially improved atomization of the liquid while maintaining optimal atomization conditions, so that even with small amounts of liquid there is a reduction in the risk of ignition, and there is an excellent extinguishing effect.
- the arrangement of the nozzle axes according to the invention also prevents an excessive obstruction of the view of the cutting unit. Since with the spraying system according to the invention there is also efficient dust deposition and chisel cooling, the spraying system according to the invention can also be used for so-called dry cutting heads, ie. H . for cutting heads that are not subject to direct chisel spraying.
