Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement cutting, in particular to a plasma cutting device. Background Art
[0002] A plasma cutting device uses the heat of a high-temperature plasma arc to partially melt (and vaporize) the metal or non-metallic material being cut. The high-speed plasma's momentum then drives the molten metal out, achieving the desired effect. While plasma cutting technology was initially used primarily for cutting metals, advancements in technology have shown broad application prospects in cement cutting.
[0003] In the production process of cement products such as cement boards, plasma cutting devices can achieve cutting of complex patterns and shapes to meet diverse design requirements.
[0004] When the plasma cutting device is working, the molten dust and flue gas are collected in a centralized manner under the action of negative pressure. When the current plasma cutting flue gas treatment device is in use, the molten flue gas will solidify when it contacts the low-temperature flue, resulting in a large amount of particulate impurities adhering to the inner wall of the flue after a period of use, affecting the smooth state of the flue.
[0005] For this reason, we propose a plasma cutting device to solve the existing problems. Utility Model Content

[0013] Preferably, legs are equidistantly mounted on the baffle, and the bottom ends of the legs are arranged on the outer wall of the inner cover.
[0014] Preferably, a support base is provided on the lower surface of the machine, and there are four support bases in total, and the positions of the four support bases are distributed in a rectangular array on the lower surface of the machine.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] During use of the utility model plasma cutting device, the plasma cutting head performs cutting operations on cement products;
[0017] During the cutting process, the outer cover moves synchronously with the plasma cutting head. At this time, it is connected to the external pump suction structure through the suction head, the external water pump structure through the nozzle, and the external sewage pipe through the discharge head. At this time, the high-temperature molten fume generated by the cutting rises along the inner surface of the inner cover under the action of negative pressure, and then passes through the baffle into the inner part of the outer cover;
[0018] At this time, the nozzle sprays water droplets to form a water curtain. The high-temperature molten flue gas collides with the water molecules, condensing and mixing with the water. The treated flue gas is finally discharged. The impurities and water mixture are blocked by the baffle, and the water flow does not enter the inner cover. Under the action of gravity, it falls between the outer cover and the inner cover and is discharged through the discharge head.
[0019] At the same time, the motor can be controlled to work regularly, and the motor drives the scraper to move along the inner wall of the inner cover, thereby scraping out the solidified impurities on the inner wall of the inner cover, making it easier to clean the flue.
[0020] The utility model can timely cool the flue gas during the process of cutting cement products with a plasma cutting device. The scraper design can facilitate regular automatic cleaning of the flue. In summary, it can avoid a large amount of impurities accumulating inside the flue that affect the smooth state of the flue.

[0030] like Figure 1-Figure 5 As shown, the utility model proposes a plasma cutting device, including a machine table 1, an outer cover 8, a scraper 16 and an inner cover 17. A slide 6 is movably provided on the machine table 1 through a sliding assembly, and a cutting head 7 is provided on the lower surface of the slide 6. The outer cover 8 is provided on the side of the slide 6, and the inner cover 17 is provided at the inner lower end of the outer cover 8. A baffle 15 is provided in the outer cover 8, and the baffle 15 is located directly above the top opening of the inner cover 17. A suction head 11, a nozzle 12, and a discharge head 13 are provided on the outer cover 8 in sequence, and a scraper 16 is rotatably provided on the inner wall of the inner cover 17.
[0031] Based on Example 1:
[0032] During use of the plasma cutting device of the present invention, cement products such as cement boards are placed on the machine table 1 and positioned under the action of their own weight. Then, the power device controls the sliding assembly of the plasma cutting device to drive the plasma cutting head 7 to move forward and backward, left and right, and up and down, so that the plasma cutting head 7 can cut the cement products.
[0033] During the cutting process, the outer cover 8 moves synchronously with the plasma cutting head 7. At this time, it is connected to the external pumping structure through the suction head 11, the external water pump structure through the nozzle 12, and the external sewage pipe through the discharge head 13. At this time, the high-temperature molten fume generated by the cutting rises along the inner surface of the inner cover 17 under the action of negative pressure, and then passes through the baffle 15 into the interior of the outer cover 8;
[0034] At this time, the nozzle 12 sprays water droplets to form a water curtain. The high-temperature molten flue gas collides with the water molecules, condensing and mixing with the water. The treated flue gas is finally discharged. The impurities and water mixture are blocked by the baffle 15. The water flow does not enter the inner cover 17. Under the action of gravity, it falls between the outer cover 8 and the inner cover 17 and is discharged through the discharge head 13.
[0035] At the same time, the motor 18 can be controlled to work regularly, and the motor 18 drives the scraper 16 to move along the inner wall of the inner cover 17, thereby scraping out the solidified impurities on the inner wall of the inner cover 17, making it convenient to clean the flue.
