- the present invention relates to a coupling device (1) for thermal lances used to pierce and / or melt cut any type of material, such as for example drilling and opening indentation passages of melting furnaces using stoppers of grease or mixtures of alumina, silica, carbon and others, comprising a hollow cylinder with beveled ends having two inner circular grooves (2 and 3) at each end of said device.
- the first groove from each end of the coupling device is called the pressure ring groove (3) and the second groove towards the center of the coupling device is called the o'ring groove (2).
- a pressure ring (4) corresponding to a hardened and tempered steel pressure ring is placed in each pressure ring groove as the name implies.
- an o'ring (5) with adequate hardness is placed in each o'ring slot to generate a good seal.
- the internal diameter of the coupling device and the size of said device depend on the diameter of the thermal lance, since each coupling device is manufactured according to the diameter of the thermal lance that needs to be coupled.
- the thermal lances to be coupled can be attachable by one of its ends or by its two ends, depending on the shape of its ends.
- the thermal lance having only one of its ends coupled with the coupling device has one of its ends with an inverted conical shape and also at said end with an inverted conical shape immediately before the start of said inverted conical end the lance has a smooth surface and cylindrical, which has an outer annular groove.
- the thermal lance that has its two ends attachable with the coupling device has its two ends with an inverted conical shape and additionally, in Each end with an inverted conical shape of the spear, prior to the start of each inverted tapered end, the spear has a smooth, cylindrical surface, which has an outer annular groove.
- the coupling between a thermal lance and the coupling device is carried out by introducing the end of the lance, which has the inverted conical shape, into one of the ends of the coupling device.
- a coupling device allows to retain up to two thermal lances at the same time, for which a thermal lance is introduced at each end of the device.
- the coupling device quickly and easily engages with the thermal lance and allows it to be firmly fixed with the lance, since by introducing the thermal lance into one of the ends of the coupling device, the pressure ring engages in the annular groove outside of the thermal lance avoiding the possibility that said lance moves and disengages, in turn the o'ring, located inside the coupling device, seals the space between the lance and the coupling device thus preventing it produce oxygen or oxidizing gas leaks.
- the coupling devices are used to couple two or three or more lances of the same outer diameter. The outer shape of the thermal lances allows easy assembly between a lance and another lance, through the coupling device of the present invention.
- the inverted tapered ends of the lance make it easy to fit with the coupling device and the outer annular groove of the lance allows to secure the fit between the lance and the coupling device.
- a small axial displacement is sufficient at the end of the lance, which allows the pressure ring to enter the lance groove and both elements are coupled without the possibility of decoupling.
- the size of the lances is variable and will depend on the application given to the lance and the location of the outer groove at each end of the lance, allows the lances not to interfere with each other when they are coupled.
- the union of a spear with another spear allows the total consumption of the spears at the time of being in use, in this way there are no remnants of spears and therefore there are no material losses, making the operation more economical.
- the shape of the lances and the coupling devices allows joining as many lances as necessary, in order to avoid losses of lances and give continuity to the operation being executed.
- the coupling device of the present invention is made of steel, which allows working in high temperature areas, up to 1,300 ° C, without melting it, since it has a high melting point, above 1,400 ° C.
- the coupling device is low cost, so that the operation costs are not raised by coupling the thermal lances with this type of coupling devices.
- the coupling device because its ignition point is lower than its melting point allows the coupling device to react in combustion together with the thermal lance when it is ignited and burned and in this way the combustion process when the lances are attached.
- the geometry of the coupling device and its dimensions determine a moment of inertia that together with the strength of the material allows to support all the mechanical stresses of tension and compression generated by the operation of the thermal lances.
- the ends of the coupling device are beveled, in order to serve as a guide to the ends of the lance, at the time of the coupling and so that the pressure ring (4) does not have to deform above its elastic limit to be mounted or inserted into the pressure ring groove (3).
- the coupling device of the present invention is easy to attach, does not require any tools or special structure for assembly, does not decouple under any operating condition and does not filter. Therefore, the use of the coupling device of the present invention brings economic benefits, since there is a better use of the thermal lances and also they achieve more efficient and safer operations, since no oxygen filtration or oxidizing gases are generated, nor unexpected decoupling, which eliminates the risks of unwanted combustion due to oxygen filtration and delays in the operation.
- the thermal lances to be coupled with the coupling device of the present invention have various uses, such as for example in the case of cutting of copper and slag, specifically in: bottoms of pot, pigs or accretions supported, peepholes, oven floors, floors of furnaces with copper and brick material, accretions in furnace walls, cleaning of the nozzle housing area, accretions in the pre-chamber gas outlet, opening of passages, refining furnace and anodes.
- the thermal lances to be coupled can also be used to efficiently open passages in copper, steel, ferroalloy, platinum and other smelting furnaces, regardless of whether the plugs have any composition, even if they are made of pure graphite (carbon). Likewise, they can be used to cut and / or drill steels of any quality or thickness, such as 1,000mm, 2,000mm, 3,000mm and more. Like, they can be used to cut concrete blocks or rocks and stones of any type and dimension.
- thermal lances to be coupled with the coupling device of the present invention can be used for cutting and / or melting of any type of material, including the diamond that is the most resistant to temperature.
