Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flame cutting equipment, and in particular to a flame cutting machine and a use method thereof. BACKGROUND

[0002] The flame cutting machine is an important steel processing equipment, which can cut and process various shapes of steel materials such as plates and rods. A large amount of cutting slag (iron oxide scale and a large amount of metal dust) is generated during cutting. In order to collect the cutting slag, a slag collecting container is usually placed on the ground below the flame cutting machine. In order to cool the cutting slag in time and efficiently, reduce the damage of high-temperature cutting slag to the container, and reduce the diffusion of dust, a certain amount of water is usually injected into the container. In order to avoid the situation that the water level in the container is too close to the flame jet of the cutting machine, the water in the container is continuously heated by the flame, a large amount of steam is generated, the air pressure is affected, and the stability of the flame jet and the cutting effect are affected, the water level in the container needs to be set far away from the flame.

[0003] Although the container storing cooling water at the bottom of the flame jet can meet the needs of collecting and cooling the cutting slag to some extent, the water level in the container is far away from the flame jet, and a large amount of dust generated during cutting cannot be effectively treated (reduced and collected). The large amount of diffused dust not only affects the working environment and brings heavy workload to the workers, but also seriously affects the service life of the parts of the flame cutting machine, and even damages the health of the workers. In addition, due to the limitation of its own structure, the cutting slag cannot be separated efficiently. In addition, because the slag collecting container placed on the ground needs to collect the splashed cutting slag, the volume generally needs to be large, it is difficult to move after collecting the slag, and it is difficult and tedious to pour out the collected cutting slag. When the flame jet needs to be repaired and maintained, the presence of the slag collecting container will seriously affect the convenience and safety of the repair and maintenance.

[0004] Therefore, there is a need for a flame cutting machine that can effectively prevent cutting dust from diffusing, has good dust collection and dust reduction effect, can automatically separate cutting slag, and is convenient to repair and maintain. SUMMARY

DETAILED DESCRIPTION

[0066] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings; the preferred embodiments of the present application are shown in the drawings, but the present application can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0067] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only embodiments.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0069] This application optimizes and improves the structure of the slag receiving container in existing flame cutting machines by using a cylindrical container for slag collection. Inside and around the cylindrical container, a liquid layer generating component is installed to spray an annular plate-shaped water layer. During use, the liquid layer is constantly flowing, allowing for slag collection close to the flame without affecting the air pressure due to high-temperature boiling, thus not impacting the cutting process. The water layer, being close to the flame, can collect the slag earlier and faster, preventing dust dispersion. Heavier slag passes through the water layer, while lighter slag is carried by the water, resulting in slag of different weights falling into different areas. Because it can collect slag close to the flame and before it disperses, a container with a large opening is not needed for collection, minimizing disruption to maintenance.

[0070] Example 1

[0071] like Figures 1 to 5 As shown, the flame cutting machine of this application includes a base frame 001, a gantry frame 002, a sliding block 003, a nozzle carrier 004, a cutting nozzle 005, a slag receiving assembly, a power assembly, and a control unit.

[0072] like Figure 2 As shown, the base frame 001 is positioned on the ground and is used to support the gantry frame 002;

[0073] The gantry 002 is a U-shaped frame with an opening facing downwards, which is slidably positioned on the base frame 001 and slides under the coordinated control of the control unit and the power component;

[0074] The sliding block 003 is slidably positioned on the gantry 002 and slides along the length (lateral direction) of the gantry 002 under the coordinated control of the control unit and the power component, thus serving to support and position the nozzle carrier 004.

[0075] The nozzle carrier 004 is rod-shaped, column-shaped, or plate-shaped, vertically arranged, and positioned on the sliding block 003 to support the cutting nozzle 005.

[0076] The cutting nozzle 005 is positioned near the bottom of the nozzle carrier 004 and is connected to the air source to spray flames for cutting.

[0077] The power assembly is used to provide power for the operation of each component of the flame cutting machine of this application, and the control unit plays the role of controlling the coordinated operation of each component of the flame cutting machine.

[0078] The base frame 001, gantry frame 002, sliding block 003, nozzle carrier 004, cutting nozzle 005, power assembly and control unit are all existing technologies and will not be described in detail here.

[0079] like Figures 3 to 5 As shown, the slag receiving assembly is located at the bottom of the cutting nozzle 005 and is used to collect, cool, store and transport slag. It includes a base bucket 110, a support bracket 120, a liquid layer generation assembly, a water blocking and splash prevention assembly, a liquid receiving container 160 and a pump assembly 170.

[0080] The base bucket 110 is a vertically arranged cylindrical bucket with an open top, an inclined inner bottom, and a bottom outlet 111 on the bottom surface. The bottom outlet 111 is equipped with a valve or cover plate controlled by the control unit.

[0081] The bearing support 120 is a rigid frame with a rod-shaped main body. The top is positioned on the sliding block 003, and the bottom is positioned on one side of the base bucket 110. It serves as a bearing and connection, allowing the slag receiving assembly to move with the sliding block 003.

[0082] The liquid layer generating component serves to generate an annular plate-shaped water layer for collecting, cooling, and sorting (separating) cutting debris. It is positioned on the base tank 110 and located at the bottom of the cutting nozzle 005. At the opening of the base tank 110, the annular plate guides the water flow to form a water layer and seals the opening. Heavier cutting debris, after contacting the water layer, will penetrate the water layer and fall to the bottom of the base tank 110 under its own weight. Lighter cutting debris (including dust) will move to the liquid receiving container 160 under the influence of the water flow.

[0083] The liquid layer generation component includes a first generation component and a second generation component;

[0084] The first generating component is located inside the base bucket 110 and includes a conveying vertical pipe 131, a top annular plate 132, a top cover 133, and a bottom telescopic rod 135.

[0085] The bottom telescopic rod 135 is a vertically arranged rigid telescopic rod that extends and retracts under the coordinated control of the control unit and the power component. It is an electric telescopic rod, with one end fixed to the inner bottom of the base bucket 110 and coaxial with the base bucket 110.

[0086] The conveying vertical pipe 131 is a rigid pipe used to convey water flow. It is coaxial with the base tank 110 and one end is fixed to the top of the bottom telescopic rod 135. Its interior is connected to the pump assembly 170.

[0087] The top annular plate 132 is a hard annular plate body, which is higher near the axis of the base barrel 110 and lower away from the axis of the base barrel 110, and the edge near the axis of the base barrel 110 is positioned at the top of the delivery vertical pipe 131 and fixed on the delivery vertical pipe 131 or integrally formed with the delivery vertical pipe 131;

[0088] The top cover body 133 is an umbrella-shaped block body coaxial with the delivery vertical pipe 131, the bottom of which is inserted into the delivery vertical pipe 131 from the top end of the delivery vertical pipe 131 and fixed on the inner wall of the delivery vertical pipe 131 by a hard frame body; the top cover body 133 is close to the top annular plate 132 and a ring-shaped gap (annular plate-shaped gap) is left between the two, which is uniform and the distance between the two is 4-8 mm;

[0089] The liquid delivered from the pump liquid assembly 170 is sprayed from the gap between the top annular plate 132 and the top cover body 133 after the delivery vertical pipe 131 to form a ring-shaped water layer; the combination of the first generating assembly and the water layer generated thereby is umbrella-shaped;

[0090] The second generating assembly is used to generate a ring-shaped water layer and cooperate with the water layer generated by the first generating assembly to close the top opening of the base barrel 110; the second generating assembly comprises a liquid delivery ring body 141, a top generating plate 142 and a bottom generating plate 143;

[0091] The liquid delivery ring body 141 is a tubular ring body fixed on the top edge of the base barrel 110 and coaxial with the base barrel 110, which communicates with the pump liquid assembly 170 through a plurality of openings and plays a role in delivering water flow; the top generating plate 142 and the bottom generating plate 143 are both annular plate bodies, the edges of which are fixed on the liquid delivery ring body 141 and relatively closer to the axis of the base barrel 110 than the liquid delivery ring body 141; the top generating plate 142 and the bottom generating plate 143 are arranged one above the other, the gap between the two is annular plate-shaped, the longitudinal section of the gap between the two is factory-shaped or oblique-rod-shaped, and the gap between the two communicates with the liquid delivery ring body 141; the liquid from the pump liquid assembly 170 flows through the liquid delivery ring body 141 and is sprayed from the gap between the top generating plate 142 and the bottom generating plate 143 to form a ring-shaped water layer and spray obliquely downward.

[0092] The water-blocking and splash-proof assembly is used to block the water layer sprayed by the first generating assembly and the second generating assembly and prevent water splashing, which comprises an annular water-blocking plate 151 and a top cover plate 152;

[0093] As shown in Figure 6 The annular water-blocking plate 151 is an annular tubular plate body located inside the base barrel 110 and coaxial with the base barrel 110, which is densely provided with through holes and / or through grooves and fixed on the liquid receiving container 160 by a hard frame body; the water sprayed by the first generating assembly and the second generating assembly impacts the inner circle and the outer circle of the annular water-blocking plate 151, respectively;

[0094] The top cover plate 152 is an annular cover body fixed at the top of the annular water-blocking plate 151, and has a longitudinal section in the shape of a V with an opening downward, for preventing water from splashing upward.

[0095] As shown in Figure 6 The liquid receiving container 160 is an open-topped hollow cylindrical container located coaxially in the base barrel 110 and fixed to the inner wall of the base barrel 110 by a rigid frame body. The spacing between the outer side wall close to the axis of the base barrel 110 and the outer side wall away from the axis of the base barrel 110 is less than or equal to the spacing between the two edges of the bottom of the top cover plate 152. The bottom of the annular water-blocking plate 151 is inserted into the liquid receiving container 160. The inner bottom of the liquid receiving container 160 is a slope and is provided with a bottom outlet 161. The bottom outlet 161 is provided with a valve or cover plate controlled by the control unit.

[0096] The pump liquid assembly 170 is a combination of a water pump, a water valve and a water delivery pipe, which is in communication with a water source and is used to pump liquid to the liquid layer generating assembly. The mixture of water and cutting slag discharged from the bottom discharge outlet 111 and the bottom outlet 161 is delivered to a solid-liquid separation device such as a sedimentation tank through a pipeline, and the discharged water can be repeatedly used.

[0097] Further, the base barrel 110 is slidingly positioned on the bearing support 120 and is lifted and lowered under the coordinated control of the control unit and the power assembly, so as to adjust the spacing between the water layer and the cutting nozzle 005 as needed, thereby improving the applicability of the slag receiving assembly.

[0098] Further, the top of the top cover body 133 is fixed with a conical top cone 134. The top cone 134 is made of metal and is used to reduce the accumulation of cutting slag on the top cover body 133.

[0099] When the flame cutting machine of the embodiment of the present application is used:

[0100] Before cutting, first control the slag receiving assembly to move upward to the bottom of the material to be cut, and ensure that the barrel opening of the base barrel 110 is at least 25 cm away from the bottom of the flame sprayed by the cutting nozzle 005.

[0101] During cutting, the first generating assembly and the second generating assembly are controlled to operate simultaneously to generate a water layer covering the barrel opening of the base barrel 110. During this period, the heavier cutting slag will penetrate the water layer and fall to the bottom of the base barrel 110 under the influence of gravity after contacting the water layer, and the lighter cutting slag (including dust) will be impacted towards the annular water-blocking plate 151 and fall into the liquid receiving container 160 under the entrapment of the water flow of the water layer. The bottom discharge outlet 111 and the bottom outlet 161 are continuously or periodically opened to discharge the solid-liquid mixture (the mixture of cutting slag and water) in the base barrel 110 and the liquid receiving container 160.

[0102] The cutting gap controls the extension and retraction of the bottom telescopic rod 135, so that the water layer generated by the first generating assembly washes the top cover plate 152 and the top generating plate 142. The bottom telescopic rod 135 can also be controlled to be retracted, and then the second generating assembly is used to wash the top cover body 133 and the top cone 134.

[0103] Preferably, the bearing support 120 is cancelled, and a frame body for bearing the base barrel 110 is arranged on the ground.

[0104] Preferably, as shown in Figure 7 and Figure 8 , the first generating assembly and the second generating assembly are both fixed with a water distribution ring 136; the water distribution ring 136 is a hard ring body with a triangular cross section; the water distribution ring 136 on the first generating assembly is arranged close to the water outlet of the first generating assembly, is inserted into the gap between the top annular plate 132 and the top cover body 133, and is fixed on the top annular plate 132 and / or the top cover body 133 through a hard frame body; due to the presence of the water distribution ring 136, the water sprayed from the first generating assembly is distributed in two layers; the water distribution ring 136 on the second generating assembly is arranged close to the water outlet of the second generating assembly, is inserted into the gap between the top generating plate 142 and the bottom generating plate 143, and is fixed on the top generating plate 142 and / or the bottom generating plate 143 through a hard frame body; due to the presence of the water distribution ring 136, the water sprayed from the second generating assembly is distributed in two layers; due to the two-layer distribution of the water sprayed from the liquid layer generating assembly, the falling heavy cutting slag passes through the two layers of water in turn, and can be turned over under the water flow during the passing, thereby being more conducive to the rapid cooling.
