Description

Technical Field

[0001] The present invention relates to the technical field of flame cutting equipment, and in particular to a slag removal processing system for flame cutting equipment. Background Art

[0002] The flame cutting machine is an important piece of equipment for continuous casting in steelmaking. It is mainly used to cut the ingots pulled out of the crystallizer by the straightening machine into billets with specific length and specific cross-sectional shape. During the continuous casting process, the flame cutting machine will produce cutting slag (iron oxide scale and a large amount of metal dust) when cutting the billets.

[0003] In order to collect the above-mentioned cutting slag, a container for collecting cutting slag is often installed under the flame cutting machine in the steelmaking continuous casting workshop. When the flame cutting machine cuts the steel billet, the cutting slag falls into the above-mentioned container. In order to cool the cutting slag in time, reduce its damage to the container and reduce dust diffusion, these containers are usually filled with a certain amount of water for cooling the cutting slag. In order to prevent the cooling water in the container from being too close to the flame of the cutting machine, thereby causing the flame (cutting flame) to heat the water in the container and produce a large amount of water vapor (due to continuous heating and / or boiling), which affects the air pressure and thus affects the stability of the flame and the cutting effect, the water level in the container needs to be set to at least 55 cm from the flame. In order to achieve the separation of cutting slag and dust, a filter layer (usually a metal filter) is usually set below the water level in the container.

[0004] Although the above scheme (using a simple method of setting up a water-containing container and setting a filter layer therein to collect the cutting slag) can effectively collect most of the cutting slag and achieve cutting slag separation to a certain extent, it is limited by its own structure and relies entirely on the natural sedimentation of the cutting slag to achieve the collection and separation of the cutting slag. The cutting slag will accumulate in large quantities directly below the flame nozzle, so that the container needs to be replaced after collecting a small amount of cutting slag, the effective capacity is small, and the filter layer is not fully utilized; the cutting slag (a mixture of iron oxide and metal dust) is basically in a stationary state after falling on the filter layer (after completing the falling and rolling action), resulting in poor separation effect and low efficiency; because the flame is far away from the water level, the dust generated after cutting splashes and diffuses in the air over a large area and for a long time.

[0005] Therefore, a slag treatment system for flame cutting equipment is needed that has high capacity utilization, full utilization of the filter layer, high efficiency and good effect in separating slag, strong operating stability, sufficient and timely cooling of slag and good dust reduction effect.

[0023] Example 1:

[0024] like Figures 1 to 4 As shown, the slag discharge processing system of the flame cutting equipment of the present application is adapted for use with the flame cutting machine 001 and is installed below the flame cutting machine 001 for collecting the cutting slag generated by the flame cutting operation, including a slag cooling assembly and a slag receiving container 200 .

[0025] The slag cooling assembly is used to disperse and quickly cool the falling slag, assist in slag separation, reduce dust, and replenish water for the slag receiving container 200, including a liquid spraying unit and a water supply assembly; The liquid spraying unit includes a water curtain generating plate 110, a plate carrier 120, a water spraying pipe 130 and a pipe carrier 140; The water curtain generating plate 110 is a hard plate with a flat top surface. It is suspended and tilted at an angle of 25 to 70 degrees to the horizontal ground. It is located obliquely below the cutting flame ejected by the flame nozzle 010 of the flame cutting machine 001. The top surface is more than 15 cm away from the bottom of the cutting flame in the vertical direction. The water curtain generating plate 110 is positioned on the flame cutting machine 001 or on the ground via a plate carrier 120. The bottom or tilted side of the water curtain generating plate 110 is positioned on the plate carrier 120. The plate carrier 120 is a rigid frame composed of rods, columns and / or plates, and serves to support the water curtain generating plate 110. The water spray pipe 130 is connected to the water supply assembly and is used to spray water toward the top surface of the water curtain generating plate 110, serving as a water flow channel. The water spray pipe 130 is directly or indirectly fixed to the plate carrier 120 via the pipe carrier 140. The water outlet of the water spray pipe 130 is located obliquely above the water curtain generating plate 110, and the angle between the sprayed water column and the water curtain generating plate 110 is 15 to 50 degrees. The pipe carrier 140 is a rigid frame composed of rods, columns and / or plates, and serves to support the water spray pipe 130. The water supply assembly is used to supply water to the water spray pipe 130 and adjust the water supply volume as needed (controlled by a control unit, which is used to control the coordinated operation of the various components of the system of this application, preferably a programmable logic controller, which is existing technology and will not be described here), is connected to the water source, and the main body is a combination of a pump, a pipe and a valve.

[0026] The slag receiving container 200 is a hard container with an open top, which is placed below the flame cutting machine 001, with the top more than 55 cm away from the bottom of the cutting flame, located at the bottom of the loose slag cooling assembly, and is used to collect and contain cutting slag; a filter layer is arranged horizontally or obliquely in the slag receiving container 200, and a drain outlet 230 is provided on the bottom or on the side wall near the bottom; water is stored in the slag receiving container 200, and the water level is at least 2 cm higher than the filter layer.

[0027] During the cutting operation, the water supply component continuously supplies water to the water spray pipe 130 and changes the water supply amount intermittently or continuously, so that the water spray pipe 130 sprays a water column toward the water curtain generating plate 110, and the water column impacts the water curtain generating plate 110 to form a water curtain and sprays it toward the bottom of the cutting flame; the formed water curtain impacts and carries away the cutting slag generated by the cutting operation under the cutting flame, and because the water flows continuously and the flow rate is relatively fast, it will move away from the cutting flame before the flame heats it to the point where a large amount of water vapor is generated; the formed water curtain is relatively close to the cutting flame, and will contact the dust as early as possible (contact the dust before the dust is widely diffused), so the dust removal and dust reduction effect is better; the formed water curtain can also flush the concentrated cutting slag away from the cutting flame, so that the water can be removed from the cutting flame. The slag is dispersed to avoid its aggregation and effectively and quickly cools down the slag to avoid the slag from damaging the filter layer or condensing (melting under heat and then condensing) on ​​the filter layer to block the filter holes after contacting the filter layer due to untimely and insufficient cooling of the slag; the change of the water supply volume of the water supply component will change the shape and landing point of the formed water curtain, avoid the concentrated accumulation of slag, make full use of the capacity of the filter layer and the slag container 200, and repeatedly impact the slag on the filter layer (making the slag turn over), helping to achieve efficient and sufficient separation of the slag; and because the water spray does not require the use of a nozzle, there is no need to worry about the nozzle clogging affecting the normal cooling of the slag, the stability is strong and the water quality requirements for the water used are low (circulating water can be used, which is relatively water-saving).

[0028] Furthermore, the water curtain generating plate 110 is a rectangular hard plate, and its length direction is parallel to the horizontal ground.

[0033] Preferably, each liquid spraying treatment unit includes a water curtain generating plate 110, a plate carrier 120, a water spraying pipe 130 and a pipe carrier 140, and a flame nozzle 010 is equipped with two liquid spraying treatment units; Figure 5 As shown, two liquid spraying treatment units matching the same flame nozzle 010 are symmetrically arranged, and the sprayed water curtains collide with each other directly below the cutting flame and then spray toward the filter layer below.

[0034] Preferably, the water curtain generating plate 110 is rotatably connected to the plate carrier 120; the water curtain generating plates 110 of the two liquid spraying treatment units matched with the same flame nozzle 010 are both equipped with a plate shifting assembly 150; during use, the angles of the water curtain generating plates 110 of the two liquid spraying treatment units are different and continuously change.

[0035] Furthermore, the filter layer is a metal filter.

[0036] Further, such as Figure 4 As shown, the slag receiving container 200 includes a basic container and a filter layer; the basic container is a hard container with an opening at the top; there are two filter layers, which are arranged one above and one below, namely the first filter layer 210 and the second filter layer 220; the first filter layer 210 and the second filter layer 220 are preferably a 10-mesh filter (screen) and a 35-mesh filter (screen), respectively. The first filter layer 210 can isolate the cut iron oxide scale, and the second filter layer 220 can isolate most of the metal dust; the water level in the basic container is more than three centimeters higher than the first filter layer 210; a drain outlet 230 is provided on the side wall of the basic container near the bottom or at the bottom; a valve with controlled opening and closing is provided on the drain outlet 230; an overflow outlet 240 is provided on the side wall of the basic container near the top, and the existence of the overflow outlet 240 ensures that the water level is always higher than a specific height (for example, 3 centimeters) of the first filter layer 210.

[0037] Further, such as Figure 7 As shown, the main bodies of the first filter layer 210 and the second filter layer 220 are hard boxes with an open top.

[0038] Furthermore, a wheel is provided at the bottom of the basic container, and the basic container is pushed away for replacement when the target storage volume is reached.

[0039] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: By changing the amount of water sprayed, the cutting slag is dispersed to avoid concentrated accumulation in one place and make full use of the filter layer; the cutting slag is hit on the filter layer by the water curtain, which promotes more complete separation of the cutting slag and greatly improves the separation efficiency; it has good stability and requires almost no maintenance (if it is a nozzle, it is easy to clog and require frequent maintenance); it saves water and can use recycled water without worrying about nozzle clogging problems; the formed water curtain can be relatively close to the cutting flame, greatly improving the dust reduction ability without generating a large amount of water vapor that affects the stability of the spray flame; the cutting slag can be cooled earlier to prevent the cutting slag from damaging the filter layer; it also plays the role of replenishing water for the container.

[0050] Example 4:

[0051] In order to prevent the accumulation of cutting slag in the space enclosed by the annular filter (although most of the cutting slag accumulated in the space enclosed by the annular filter will be gradually filtered out or fall from the edge to the second filter layer 220 over time, its presence in the space enclosed by the annular filter will accelerate the wear of the annular filter to a certain extent, affecting the actual service life of the annular filter and the support belt drum), the embodiment of the present application optimizes and improves the structure of the slag container 200 based on the above embodiment, specifically: like Figure 15 and Figure 16 As shown, the slag receiving container 200 includes a base container, a filter layer and a roll carrier 250; The basic container is a rectangular block-shaped box container with an open top; The filter layer includes a first filter layer 210 and a second filter layer 220, which are arranged one above the other. The slag conveying assembly 211 and two belt pressing rollers 213 form the first filter layer 210. The structure of the second filter layer 220 is the same as that of Example 3. The roll carrier 250 is a vertically arranged hard plate body, which is fixed on the top of the base container near both sides and plays a role of bearing support; The slag conveying assembly 211 is in the shape of a reel as a whole, and includes a first reel 216, a second reel 217 and a filter belt 218; the first reel 216 and the second reel 217 are both arranged horizontally, and are respectively positioned on the reel carrier 250 on the top of the basic container near both sides, both are higher than the water level, and are both located obliquely above the basic container. At least one of them has a built-in motor or is rotated by the motor; the filter belt 218 is an annular metal mesh, and its two ends are respectively wound and positioned on the first reel 216 and the second reel 217 to screen and separate the slag. The distance between the edge and the inner wall of the basic container is less than 0.5 cm. Most of the filter belt 218 not wound on the first reel 216 and the second reel 217 is located below the water level under the restriction of the belt pressing roller 213; The two belt pressing rollers 213 are located on top of the filter belt 218 and are close to the roll carriers 250 on both sides. They always contact the annular filter screen and are arranged horizontally. The ends are positioned on the inner wall of the base container and also play a role in tensioning the filter belt 218. The water level in the base container is higher than the bottom surface of the belt holding roller 213; During the cutting operation, the first drum 216 and the second drum 217 rotate back and forth, replacing the filter belt 218 immersed in water and transporting the filtered cutting residue out from both sides.

[0052] Furthermore, in order to prevent the cutting slag from falling onto the annular filter in the air and causing damage thereto, a top baffle 260 is fixed to the roll carrier 250; the top baffle 260 is a hard plate body arranged horizontally to cover the filter belt 218 exposed to the air.

[0053] Example 5:

[0054] In order to further ensure and maintain the separation effect of the filter layer, the embodiment of the present application is additionally provided with a dredging column 290 on the basis of the above embodiment, and the dredging column 290 is used to dredge and maintain the annular filter screen or filter belt 218 in real time; specifically: like Figure 17 As shown, the dredging column 290 is a hollow cylinder with a surface densely covered with pointed cones, and there are one or more of them. The axial length is 1 to 3 cm shorter than the width of the base container, and the length direction is always the same as the width direction of the base container. The dredging column 290 will float after being put into water; when in use, it is placed in the space surrounded by the annular filter screen or at the bottom of the filter belt 218, always contacting the annular filter screen or the filter belt 218; the pointed cone on the dredging column 290 corresponds to the filter holes on the annular filter screen and the filter belt 218; during the movement of the annular filter screen and the filter belt 218, the dredging column 290 is driven to rotate, thereby dredging the filter holes in real time; and the impact of the falling water curtain also drives the dredging column 290 to move up and down, further improving the dredging effect; the dredging column 290 does not require additional power for dredging and has good stability, and can promptly dredge the cutting residue that blocks the filter holes (further effectively preventing the cutting residue from melting and clogging the filter holes due to residual heat); when the water curtain hits the dredging column 290, the up and down floating of the dredging column 290 will also drive the water near the filter holes near the dredging column 290 to flow rapidly, flushing the filter holes while assisting in the separation of the cutting residue and the heat exchange.

[0055] Preferably, a dredging column 290 is also provided at the bottom of the second filter layer 220. The dredging column 290 located here is positioned in the base container by a soft rope positioned at the end of the dredging column 290; the end of the soft rope is rotatably connected to the dredging column 290 or the inner wall of the base container.
