It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0025] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.
[0026] A smoke removal mechanism for a plasma cutting machine provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Embodiment 1
[0027] Combination Figure 1-4 As shown, the utility model provides a smoke removal mechanism for a plasma cutting machine, comprising a dust suction module 100 and a filter module 200, wherein the dust suction module 100 comprises a cutting gun 110, two brackets 120 installed at the front and rear sides of the cutting gun 110, a clamp 130 installed at the inner side of the bracket 120, a treatment barrel 140 connected between the two clamps 130, a barrel cover 150 movably connected to the bottom end of the treatment barrel 140, a frame 160 connected between the two brackets 120, an air pump 170 connected between the treatment barrel 140 and the frame 160, a dust suction pipe 180 connected and communicated with the air pump 170, and a shell 190 sleeved on the bottom end of the dust suction pipe 180;
[0028] The filter module 200 includes a clamping strip 210 installed on one side of the treatment barrel 140, a snap-on plate 220 integrally formed with the barrel cover 150, a motor 230 connected to the bottom of the barrel cover 150, a turntable 240 disposed inside the treatment barrel 140 and connected to the output shaft of the motor 230, two stirring blades 250 connected to the top of the turntable 240, and a filter screen plate 260 installed inside the treatment barrel 140, wherein the snap-on plate 220 is snap-connected with the clamping strip 210.
[0029] Furthermore, the treatment tube 140 is composed of a large hollow tube and a small hollow tube. The large hollow tube is sleeved on the bottom end of the small hollow tube, and the two are internally interconnected. The filter plate 260 is located inside the small hollow tube. This structural design can reduce the probability of liquid spilling from the top of the treatment tube 140.
[0030] Furthermore, the bottom of the turntable 240 fits with the top of the barrel cover 150 and has a diameter smaller than that of the barrel cover 150 . With this size design, the turntable 240 will not contact the inner wall of the treatment cylinder 140 when rotating, effectively avoiding wear of the turntable 240 and the treatment cylinder 140 .
[0031] Furthermore, the two stirring blades 250 are vertically symmetrical about the center of the turntable 240 , and the stirring blades 250 are made of a plastic material. The stirring blades 250 made of the plastic material are not afraid of being soaked in water, thus ensuring the service life of the stirring blades 250 . Embodiment 2
[0032] Combination Figure 1-2 As shown, based on the first embodiment, two bolts 300 are connected between the two brackets 120 , and the two bolts 300 are vertically symmetrical about the vertical center plane of the cutting spray gun 110 . The two bolts 300 can improve the connection firmness of the two brackets 120 . Embodiment 3
[0033] Combination Figure 1-4 As shown, in the above embodiment, the frame 160 and the air pump 170 are both located between the cutting spray gun 110 and the processing tube 140, and the air pump 170 is connected in series with the motor 230. This structural design makes it convenient for the staff to start and close the air pump 170 and the motor 230 at the same time.
[0034] The working principle and use process of the utility model are as follows: before using the device, clean water is injected into the treatment barrel 140. Then, when the device is put into actual use, once the cutting spray gun 110 works, the air pump 170 and the motor 230 will also work. The air pump 170 extracts the smoke generated by cutting through the dust suction pipe 180 and the shell 190, and then injects it into the interior of the treatment barrel 140. Here, the output shaft of the motor 230 drives the turntable 240 and the stirring blade 250 to rotate. The stirring blade 250 causes the clean water to flow in a vortex shape and then absorbs the particles in the smoke. These particles move continuously with the water flow to prevent them from adhering to the inner wall of the barrel. Then, the gas in the treatment barrel 140 is safely discharged after passing through the filter screen 260. Then, when cleaning the interior of the treatment barrel 140, the buckle plate 220 and the card strip 210 are separated, and then the sewage in the barrel can fall directly. Then, a small amount of clean water is injected from the top of the treatment barrel 140 to complete the cleaning of the inner wall of the barrel and the barrel cover 150, and the cleaning is easy.
[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
