[0002] A carbon arc gouging machine is a machine that uses an electric arc generated between a graphite rod or a carbon rod and a workpiece to melt the metal, and blows it off with compressed air to achieve the purpose of processing grooves on the metal surface. During the use of the carbon arc gouging machine, smoke will be generated, so a smoke treatment device is required to treat the smoke to avoid air pollution.

Since the fumes flow upward quickly in the solution, it is difficult for the fumes to fully contact with the solution, resulting in poor fumes treatment effect.

[0004] Therefore, a fume treatment device for a carbon arc gouging machine is proposed. Utility Model Content

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a fume treatment device for a carbon arc gouging machine, such as Figure 1-4 As shown, it includes a flue gas treatment box 1, the interior of the flue gas treatment box 1 is filled with a solution containing sodium peroxide, a flue gas inlet pipe 2 is embedded on the outer wall of one side of the flue gas treatment box 1, and an outlet pipe 3 is embedded on the top of the flue gas treatment box 1, the flue gas inlet pipe 2 and the outlet pipe 3 are both connected to the flue gas treatment box 1, a partition 4 is fixedly connected to the inner wall of one side of the flue gas treatment box 1 by bolts, a sedimentation trough 5 and a guide hole 6 are opened on the top of the partition 4, the sedimentation trough 5 is located on one side of the guide hole 6, and a motor 7 is fixedly connected to the upper side of the outer wall of one side of the flue gas treatment box 1 close to the partition 4 by bolts, and the motor 7 is connected by The output end on one side is fixedly connected to a rotating rod 8, a bubble breaking disk 9 is welded on an outer wall of one side of the rotating rod 8, and an impeller 10 is welded at one end of the rotating rod 8 near a side of the bubble breaking disk 9, the outer diameter of the bubble breaking disk 9 is smaller than the outer diameter of the impeller 10, the bubble breaking disk 9 and the impeller 10 are located inside the flue gas treatment box 1, and the bubble breaking disk 9 and the impeller 10 are located above the sedimentation tank 5, a bubble breaking hole 11 is opened on an outer wall of one side of the bubble breaking disk 9 near a side of the impeller 10, and a sealing cover 12 is hinged at an upper side position near the partition 4 on an outer wall of one side of the flue gas treatment box 1.

[0022] It should be noted that, since the existing carbon arc gouging machine will produce a large amount of nitric oxide and nitrogen dioxide when working, these flue gases need to be treated with a solution containing sodium peroxide. Since the flue gas will flow upward quickly in the solution, it will be difficult for the flue gas to fully contact with the solution, resulting in poor flue gas treatment effect. In this embodiment, the internal space of the flue gas treatment box 1 is divided by the partition 4, so that the flue gas bubbles in the flue gas treatment box 1 can move from bottom to top in an S-shaped moving trajectory, thereby increasing the movement path of the flue gas, facilitating the flue gas to fully contact with the solution in the flue gas treatment box 1, achieving adsorption treatment of nitric oxide and nitrogen dioxide in the flue gas, and improving the treatment effect. Through the mutual cooperation of the impeller 10 and the bubble breaking disk 9, the flue gas bubbles can be divided into multiple small bubbles by the bubble breaking holes 11 and flow with the solution, so that the flue gas is fully in contact with the solution, further improving the treatment effect.

[0023] Specifically, in this embodiment, this scheme mainly includes a partition 4 and a bubble crushing disk 9. When in use, the smoke outlet of the carbon arc air planer is connected to the smoke inlet pipe 2, and the smoke generated by the carbon arc air planer enters the smoke treatment box 1 through the smoke inlet pipe 2. The smoke contacts with a solution containing sodium peroxide, and the smoke is in the form of bubbles in the solution. The bubbles flow upward through the guide holes 6 on the partition 4. At this time, the motor 7 drives the rotating rod 8 to rotate at a high speed through the output end on one side thereof, and the bubble crushing disk 9 and the impeller 10 on the rotating rod 8 rotate at a high speed. The impeller 10 During the rotation, the solution is pushed and the bubbles move with the solution. After the bubbles come into contact with the bubble breaking disk 9, they are divided into multiple small bubbles by the bubble breaking holes 11 and flow with the solution, so that the flue gas is fully in contact with the solution. The nitric oxide and nitrogen dioxide in the flue gas are absorbed and precipitated after encountering sodium peroxide, thereby treating the flue gas. The treated flue gas is discharged through the exhaust pipe 3. When it is necessary to clean the sediment in the sedimentation tank 5, the sealing cover 12 is opened to scrape out the sediment in the sedimentation tank 5, and finally the sealing cover 12 is closed for sealing.

[0024] In a further preferred embodiment of the present invention, Figure 2 As shown, there are five partitions 4 in total, and the five partitions 4 are evenly spaced and distributed on the inner wall of the flue gas treatment box 1 , and the guide holes 6 on the five partitions 4 are staggered with each other.

[0025] In this embodiment, by setting up five partitions 4 and by means of mutually staggered guide holes 6, the flue gas bubbles in the flue gas treatment box 1 can move from bottom to top in an S-shaped trajectory, thereby increasing the movement path of the flue gas, facilitating full contact between the flue gas and the solution in the flue gas treatment box 1, and realizing the adsorption treatment of nitric oxide and nitrogen dioxide in the flue gas.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, a discharge groove is provided on one side of the outer wall of the flue gas treatment box 1 near the sealing cover 12 .

[0027] In this embodiment, by providing the discharge trough, the precipitate in the sedimentation trough 5 on the partition 4 can be taken out after opening the sealing cover 12, thereby ensuring smooth flow of smoke in the space between the two partitions 4.
