when in use, the port of the air suction pipe 3 is connected with an external waste gas collecting pipeline, a user controls the motor on the driving piece 4 to start, the radio frequency power source 2901 is started under the control of an electric control device (a well-known electric control device is adopted) of the processing system, and the radio frequency power source 2901 supplies power to the corresponding outer electrode cover 2903 and the corresponding inner electrode cover 2904 through the electric conduction cable 2902.
The inner electrode cover 2904 is a low-voltage electrode, since the inner wall of the medium workpiece 2905 is close to the inner electrode cover 2904, at this time, a discharge phenomenon and a strong electromagnetic field are generated between the medium workpiece 2905 and the gap of the inner electrode cover 2904, in the process, the electric control device of the processing system can control the air pump 25 to start, and the sealing ball 27 forms a one-way exhaust structure of the processing cylinder 23, so that the air pump 25 can extract air in the processing cylinder 23 through the butt joint hole 2203 and the connecting pipe 24, the air pressure of the processing cylinder 23 is reduced, the molecular spacing and the free movement distance of molecules or ions are prolonged along with the thinner and thinner air, the strong magnetic field is acted, the collision is generated so as to generate plasmas quickly, and glow is generated simultaneously, so that the dual-medium blocking is realized through the two plasma generating mechanisms.
At this time, the driving piece 4 will drive the fan blade 10 to rotate, the fan blade 10 will suck the external waste gas into the gas storage tube 2 through the gas suction tube 3 and the air vent 20, at this time, the waste gas in the gas storage tube 2 will be continuously increased, in this process, the main shaft of the driving piece 4 will drive the main gear 6 to rotate through the power gear 5, the main gear 6 and the auxiliary gear 7 form a reduction gear, so that the main gear 6 can drive the toothed ring 8 to slowly rotate through the auxiliary gear 7, the toothed ring 8 will drive the first rotating disc 902 to synchronously rotate through the connecting ring 901, and at this time, the first rotating disc 902, the second rotating disc 903 and the third rotating disc 904 simultaneously rotate anticlockwise.
When the third turntable 904 rotates by a certain angle, the chute on the third turntable 904 is opposite to the end part of the ball rod 11, the pressure spring 13 pushes the ball rod 11 to move in the outer cylinder 12 through the reset action, so that the convex ball at the end part of the ball rod 11 can enter the chute on the third turntable 904, when the third turntable 904 continues to rotate, the chute surface on the third turntable 904 applies pressure to the end part of the ball rod 11, so that the ball rod 11 can drive the outer cylinder 12 to move upwards, the outer cylinder 12 drives the loading frame 14 to synchronously move upwards, the movable plate 15 at the top of the loading frame 14 compresses the reset spring 19, in the process, the movable plate 15 at the top of the loading frame 14 applies pressure to the cross rod on the control plate 17 through the guide groove 16, so that the control plate 17 can horizontally move, the vent 20 on the control plate 17 is not communicated with the air suction pipe 3 any more, the control plate 17 can seal the air suction pipe 3, and the inclined block 21 on the control plate 17 just contacts with the inclined plane at the center of the top of the lifting table 2202.
Following the above steps, the first turntable 902, the second turntable 903 and the third turntable 904 continue to rotate anticlockwise, and as can be seen from the above steps, the club 11 enters the chute of the second turntable 903, the chute of the second turntable 903 can push the club 11 and the loading frame 14 upwards again, and the moving plate 15 on the loading frame 14 drives the control plate 17 to move again through the guiding slot 16, and the inclined block 21 on the control plate 17 applies pressure to the lifting table 2202, so that the lifting table 2202 moves upwards.
The lifting table 2202 drives the pull rod 2204 to elastically stretch out, at this moment, the top of the lifting table 2202 does not plug the port of the treatment cylinder 23 any more, at the same time, the lifting table 2202 plugs the port of the air pump 25, at this moment, the air storage pipe 2 is communicated with the treatment cylinder 23, the fan blades 10 can send waste gas into the treatment cylinder 23, high-energy plasmas in the treatment cylinder 23 can bombard the gas, so that substances such as ozone, hydroxyl free radicals and small molecular fragments are generated, and the waste gas is purified, so that the waste gas can stay in the treatment cylinder 23 for a long time and is sufficiently purified.
Then the first turntable 902, the second turntable 903 and the third turntable 904 continue to rotate anticlockwise, at this time, the ball rod 11 moves along the outer disk surface of the third turntable 904, the convex ball of the ball rod 11 moves along the limit groove on the reset table 905, so that the ball rod 11 can move inwards to compress the pressure spring 13 again in the outer cylinder 12, when the ball rod 11 moves to the outlet of the reset table 905, the limit groove on the reset table 905 does not limit the end part of the ball rod 11 any more, and at this time, the reset spring 19 pushes the moving plate 15 to move downwards through the reset action.
The movable plate 15 drives the ball rod 11 and the outer cylinder 12 to synchronously move downwards through the loading frame 14 to restore to the original position, meanwhile, the movable plate 15 can push the control plate 17 to horizontally reset and move, so that the inclined block 21 is far away from the top inclined plane of the lifting platform 2202, at the moment, the pull rod 2204 elastically contracts and resets, the pull rod 2204 drives the lifting platform 2202 to block the port of the treatment cylinder 23 again, the air pump 25 can reduce the air pressure in the treatment cylinder 23 again, the air pump 25 can send redundant air into the post-treatment box 26 to be discharged again, and then the air port 20 on the control plate 17 is communicated with the air suction pipe 3 again so as to carry out the next cycle, and the intermittent entry of waste gas in the treatment cylinder 23 is realized through the steps, so that the treatment time of the waste gas is prolonged, and the purification treatment effect is improved.
