As shown in fig. 7, when the turntable 63 moves downward so that the third magnetic ring 64 abuts against the first magnetic ring 25 and the fourth magnetic ring 65 abuts against the second magnetic ring 26, and d is set to be greater than e, the third magnetic ring 64 or the fourth magnetic ring 65 is not accommodated in the space between the first magnetic ring 25 and the second magnetic ring 26 when the turntable 63 rotates, so that the turntable 63 can rotate smoothly.
The magnetic structure 6 is arranged such that when the lifting frame 54 moves downward, the turntable 63 moves downward, the lower surface of the third magnetic ring 64 has the same magnetic pole as the upper surface of the first magnetic ring 25, and the lower surface of the fourth magnetic ring 65 has the same magnetic pole as the upper surface of the second magnetic ring 26, under the action of repulsion force of the same magnetic pole, the blocking plate 24 stably abuts against the partition plate 22, then the flue gas above the partition plate 22 enters the lifting frame 54, and the flue gas is rapidly introduced into the second filter frame 33 through the sixth through hole 541 due to being pressed by the lifting frame 54, so that the flue gas can be rapidly purified and filtered, the flue gas can rapidly pass through the filter holes of the second filter frame 33, when the turntable 63 moves upward, the second motor 61 drives the second rotating shaft 62 and the turntable 63 to rotate 180 degrees, the third magnetic ring 64 is above the second magnetic ring 26, and the fourth magnetic ring 65 is above the first magnetic ring 25, the lower surface of the third magnetic ring 64 and the upper surface of the second magnetic ring 26 have different magnetic poles, the lower surface of the fourth magnetic ring 65 and the upper surface of the first magnetic ring 25 have different magnetic poles, and the different magnetic poles attract each other, so that the blocking plate 24 moves upward along with the turntable 63, and at this time, the flue gas below the second casing 21 can enter the first filter frame 23 and then enter the upper part of the partition plate 22 through the filter holes of the first filter frame 23, so that the unidirectional flow of the flue gas can be realized, the purified liquid can be prevented from entering the cement production equipment, and the backflow of the flue gas can be prevented.
As shown in figures 1 to 7, when the environment-friendly cement kiln flue gas purification treatment system is used, the lower end of the second shell 21 is firstly aligned with the cement kiln flue gas outlet, so that flue gas generated by the cement kiln enters the second shell 21. Then, the purified liquid or water is poured into the first housing 11 and is located above the collecting plate 41. Then, the switch of the first motor 51 is turned on, so that the first rotating shaft 52 periodically rotates forward and backward, the first rotating shaft 52 periodically rotates forward and backward to drive the fixing plate 32, the rotating frame 31, the second filtering frame 33 and the filtering bristles 34 to periodically rotate forward and backward, the periodic forward and backward rotation of the second filtering frame 33 and the filtering bristles 34 can effectively prevent impurities from being deposited on the second filtering frame 33 and the filtering bristles 34, thereby being beneficial to shaking out the impurities, ensuring the continuous and efficient purification of the flue gas, and preventing the occurrence of blockage, meanwhile, the rotation of the rotating frame 31 can periodically communicate the fourth through holes 311 with the fifth through holes 421, so that the purifying liquid or water above the concentrating plate 41 periodically flows into the rotating frame 31 through the fifth through holes 421 and the fourth through holes 311, then wets the filtering bristles 34, even the second filtering frame 33, and enhances the effects of the filtering bristles 34 and the second filtering frame 33 on purifying and removing impurities of the flue gas, play the effect of scrubbing simultaneously to it, prevent impurity deposit once more, need not in the continuous inflow of scavenging solution or water to the rotating frame 31 simultaneously, reduce the waste of resource, practice thrift the cost, make it can last the high efficiency go on. On the other hand, the periodic positive and negative rotation of the first rotating shaft 52 causes the periodic up-and-down movement of the connecting frame 53 and the lifting frame 54, when the lifting frame 54 moves downwards, the magnetic structure 6 moves downwards, the air below the lifting frame 54 enters the space between the lifting frame 54 and the second filter frame 33 through the sixth through hole 541, then enters the outside of the second filter frame 33 after being filtered by the filter bristles 34 and the second filter frame 33, and finally is discharged through the first through hole 111, and the rotating disc 63, the third magnetic ring 64 and the fourth magnetic ring 65 move downwards along with the lifting frame, because the lower surface of the third magnetic ring 64 is the same as the magnetic pole of the upper surface of the first magnetic ring 25 below the third magnetic ring 64, and the lower surface of the fourth magnetic ring 65 is the same as the magnetic pole of the upper surface of the second magnetic ring 26, even if the rotating disc 63 moves downwards, the blocking plate 24 can still stably abut against the partition plate 22 due to the repulsion of the same magnetic poles, at this time, when the lifting frame 54 moves downwards, smoke below the lifting frame can rapidly pass through the sixth through hole 541, the filter bristles 34 and the second filter frame 33 for filtering, so that the speed of the smoke passing through the filter holes and the filter bristles 34 is increased, the situation that impurities are easily deposited on the filter bristles 34 and the filter holes of the second filter frame 33 due to too low speed is prevented, the lifting frame 51 moves downwards and also drives the baffle 55 to move downwards, the baffle 55 moves downwards to stir the end part of the filter bristles 34 to drive the baffle to swing, so that the impurities deposited on the filter bristles 34 can be shaken off, and the cleaning effect is remarkable; when the lifting frame 54 moves upward, the second motor 61 drives the second rotating shaft 62 and the rotating disc 63 to rotate 180 degrees, so that the fourth magnetic ring 65 moves above the first magnetic ring 25, the third magnetic ring 64 moves above the second magnetic ring 26, because the lower surface of the fourth magnetic ring 65 is different from the magnetic pole of the upper surface of the first magnetic ring 25, and the lower surface of the third magnetic ring 64 is different from the magnetic pole of the upper surface of the second magnetic ring 26, the fourth magnetic ring 65 adsorbs the first magnetic ring 25, and the third magnetic ring 64 adsorbs the second magnetic ring 26, so that the blocking plate 24 moves upward along with the rotating disc 63, at this time, the flue gas generated in the cement pit below the second shell 21 enters the first filtering frame 23, then enters the partition plate 22 through the filtering holes of the first filtering frame 23, and then is concentrated above the partition plate 22, so that the flue gas flow is accelerated and the flue gas is rapidly purified and filtered when the lifting frame 54 moves downward next time, after the turntable 63 moves upward for a certain distance, because the first spring 28 is compressed all the time, the elastic force of the first spring 28 is gradually increased, then the first spring 28 pushes the fixing block 27 downward, so that the first filter frame 23 and the blocking plate 24 move downward, and the blocking plate 24 abuts against the partition plate 22, the second motor 61 drives the second rotating shaft 62 to rotate 180 degrees again, at this time, the fourth magnetic ring 65 moves to the upper side of the second magnetic ring 26, and at the same time, the third magnetic ring 64 moves to the upper side of the first magnetic ring 25, so that the lifting frame 54 is convenient to prevent the smoke from flowing downward when moving downward, and the steps are continuously repeated to continuously purify the smoke until the smoke is purified. The use process of the environment-friendly cement pit flue gas purification treatment system is described.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and the changes or substitutions should be covered within the scope of the present invention.
