According to the type of gas used, flame cutting can be divided into oxyacetylene flame cutting (commonly known as gas cutting), oxypropane flame cutting, oxygen natural gas flame cutting and oxyhydrogen flame cutting. The most widely used in actual production are oxyacetylene flame cutting and oxypropane flame cutting. Flame cutting of steel uses a gas flame to heat the surface of the steel to a temperature that can burn in an oxygen flow, and then feeds in high-purity, high-flow cutting oxygen to make the iron in the steel burn in an oxygen atmosphere to generate iron oxide slag. With the help of these combustion heat and slag, the lower layer of the steel and the front edge of the cut are continuously heated to reach the ignition point, until the bottom of the workpiece, the cutting oxygen flow blows away the iron oxide slag, thus forming an incision to cut the steel.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a flame cutting auxiliary device, including a slag water tank 1, a filter plate 2 is built in the slag water tank 1, a lifting mechanism 3 is arranged on both sides of the upper end of the slag water tank 1, a smoke collecting mechanism 4 is arranged on the slag water tank 1, the lifting mechanism 3 includes a reel base 31, a reel base 31 is built with a reel, and a reel rope 33 is wound on the reel, and one end of the reel is connected to a motor 32, and the output shaft of the motor 32 is fixed to the reel, and the smoke collecting mechanism 4 includes a first smoke collecting hood 41, a second smoke collecting hood 42, a smoke collecting box 43 and a filter box 45.

[0024] Among them, the slag water tank 1, the filter plate 2, the lifting mechanism 3 and the smoke collection mechanism 4 together constitute a flame cutting auxiliary mechanism, which is placed under the flame cutting frame and the cutting platform. Cooling water without the filter plate 2 is pre-introduced into the slag water tank 1. During the flame cutting process, the slag falling from the top will fall into the slag water tank 1. The slag is cooled and solidified by the water and is retained on the filter plate 2. The slag water tank 1 receives a large amount of slag generated during the flame cutting process, and the slag is cooled and collected, which is convenient for the subsequent recovery and treatment of the slag.

[0025] The motor 32 drives the winding wheel to rotate when working, and the rotation direction of the winding wheel is controlled by controlling the rotation direction of the motor 32. The rotating winding wheel winds up or extends the winding rope 33.

[0026] When the winding wheel reels the winding rope 33, the winding rope 33 drives the filter plate 2 to slide along the slide groove 131 of the slide bar 13, so that the filter plate 2 moves upward, and the filter plate 2 drives the solid slag collected on the upper part thereof to move upward synchronously, so that the slag is removed from the cooling water, which is beneficial to the subsequent treatment of the slag;

[0027] When the reel-in wheel lengthens the reel-in rope 33 , the filter plate 2 slides down along the slide groove 131 of the slide bar 13 by its own gravity, so that the filter plate 2 is immersed in the cooling water.

[0028] Among them, the smoke collection box 43 is connected to the first smoke hood 41 and the second smoke hood 42 through a smoke collection pipeline 44. The first smoke hood 41 is located at the front end of the slag water tank 1, and the second smoke hood 42 is located at the rear end of the slag water tank 1. The smoke generated during the flame cutting process is absorbed by the first smoke hood 41 and the second smoke hood 42.

[0029] Among them, a first filter screen 21 is arranged on the filter plate 2, and slide bars 13 are arranged at the corners of the inner side of the slag water tank 1, and a slide groove 131 is opened on the slide bar 13. The filter plate 2 is slidingly connected with the slide groove 131 of the slide bar 13, and the end of the winding rope 33 is fixed to the filter plate 2. The slide groove 131 of the slide bar 13 plays a guiding role. The filter plate 2 can move axially along the slide groove 131 of the slide bar 13 under the drive of the lifting mechanism 3 to adjust the position of the filter plate 2.

[0030] The first smoke hood 41 and the second smoke hood 42 are both provided with a second filter 46 on their inner sides. The second filter 46 plays a filtering role to prevent large particles of impurities from entering the smoke hood and the smoke collection pipeline 44 to prevent the pipeline from being blocked.

[0031] Among them, a cover plate 431 is set at the top of the smoke dust collection box 43, and the cover plate 431 and the smoke dust collection box 43 are fixed by a slot. The connection method is simple. The cover plate 431 can be removed by applying a certain external force, which is convenient for cleaning the smoke dust collection box 43.

[0032] The filter box 45 has a filter element 451 built therein, a connector 452 is provided at one end of the filter box 45 , and the connector 452 is threadedly connected to the smoke collecting box 43 , so that the filter box 45 is easy to install and disassemble.

[0033] The other end of the filter box 45 is provided with a connecting pipe 453 , and the connecting pipe 453 is connected to the induced draft fan assembly, which is the power source of the smoke collecting mechanism 4 .

[0034] During the flame cutting process, smoke is collected by the smoke collecting mechanism 4, and the induced draft fan assembly works to generate negative pressure adsorption force in the smoke hood. The smoke enters the first smoke hood 41 and the second smoke hood 42 under the action of negative pressure, enters the smoke collecting pipeline 44 through the first smoke hood 41 and the second smoke hood 42, and enters the smoke collecting box 43 through the smoke collecting pipeline 44. The smoke is filtered by the filter box 45, and the filtered airflow is discharged through the pipeline to prevent the smoke from polluting the workshop environment and affecting other equipment.

[0035] The slag water tank 1 stores cooling water inside, and the cooling water covers the filter plate 2 . The slag dropped from the top will fall into the slag water tank 1 . The slag is cooled and solidified by the water and is retained on the filter plate 2 .

[0036] A drain pipe 11 is provided below one side of the slag water tank 1 , and a valve 12 is provided on the drain pipe 11 . The valve 12 is opened to replace the cooling water through the drain pipe 11 .

[0037] Working principle: the slag water tank 1, the filter plate 2, the lifting mechanism 3 and the smoke collecting mechanism 4 together constitute a flame cutting auxiliary mechanism, which is placed under the flame cutting frame and the cutting platform. The cooling water without the filter plate 2 is pre-introduced into the slag water tank 1. The connecting pipe 453 of the smoke collecting mechanism 4 is connected to the induced draft fan assembly, and the induced draft fan assembly is used as the power source of the smoke collecting mechanism 4. During the flame cutting process, the slag falling from the top will fall into the slag water tank 1. The slag is cooled and solidified by water and is trapped on the filter plate 2. The slag water tank 1 receives a large amount of slag generated during the flame cutting process, and the slag is cooled and collected. The smoke generated during the flame cutting process is collected by the first smoke collecting hood 41 and the second smoke collecting hood 42. The smoke enters the smoke collecting pipe 44 through the first smoke collecting hood 41 and the second smoke collecting hood 42, and enters the smoke collecting box 43 through the smoke collecting pipe 44. The smoke is filtered by the filter box 45, and the filtered airflow is discharged through the pipe. After the flame cutting is completed, the motor 32 drives the winding wheel to wind up the winding rope 33, and the winding rope 33 drives the filter plate 2 to slide along the slide groove 131 of the slide bar 13, so that the filter plate 2 moves up, and the filter plate 2 drives the solid slag collected on the upper part thereof to move up synchronously, and removes the slag from the cooling water. After the slag is cleaned and recovered, the motor 32 drives the winding wheel to lengthen the winding rope 33, and the filter plate 2 relies on its own gravity to slide down along the slide groove 131 of the slide bar 13, so that the filter plate 2 is immersed in the cooling water again.
