[0026] The purification component 6 includes a filter screen 61, and the filter screen 61 is connected to an annular bracket 62. The bracket 62 is installed on the separation ring 3, and the bracket 62 is fixedly installed on the inner wall of the separation ring 3. A connecting port 63 cooperating with the filter screen 61 is provided on the side of the separation ring 3, and an air inlet 65 connected with the connecting port 63 is provided on the side wall of the main pipe 1. The bracket 62 is provided with multiple groups of protruding parts at the intervals of multiple adjacent connecting ports 63, and filter screens 64 are provided on both sides of the protruding parts. Multiple air intake pipes 5 are arranged in pairs at the protruding parts, and the two air intake pipes 5 of each pair are directly opposite to the two filter screens 64 of the protruding parts, so that the two air intake pipes 5 directly opposite to each other will act on the two filter screens 64 respectively, so that the filter screens 64 far away from each other can be recoiled and cleaned, that is, by controlling different air intake pipes 5 to intake air, it can be Different filter screens 264 have the function of cleaning. A buffer part 66 of a trapezoidal structure is connected to one side of the raised part close to the fixed ring 4. The end of the buffer part 66 is against the inner wall of the fixed ring 4 through a buffer layer of rubber material, so that the raised part can finally be relatively sealed with the inner part of the fixed ring 4. In this way, when the raised part rotates, the floating solid impurities or dust in the space inside the fixed ring 4 can be collected and concentrated on the filter screen 264 for cleaning. The rotating component 9 includes a gear ring 91 fixedly connected to the outer wall of the separation ring 3, the inner part of the gear ring 91 is sleeved on the main pipe 1 and rotatably connected to the main pipe 1, and a gear 92 is meshed at the bottom of the gear ring 91.

[0027] The discharge assembly 8 includes two friction rollers 81 symmetrically arranged in the storage box 7, each friction roller 81 is connected to a group of support rods 82 at both ends, each group of support rods 82 includes two support rods 82, a tension spring is connected between the two support rods 82 on the same side and they are commonly connected to a bottom plate 83, the bottom plate 83 is connected to a moving assembly that enables the two friction rollers 81 to move in the vertical direction, the moving assembly includes a slide rail 84 connected to two symmetrical inner side walls of the storage box 7, a slider 85 is installed in the slide rail 84, a receiving groove 88 is opened on the side wall of the storage box 7, the slide rail 84 and the slider 85 are both arranged in the receiving groove 88, so as to avoid affecting the movement of the extraction box 11, the two sliders 85 are respectively fixed to the two ends of the bottom plate 83, the bottom plate 83 A plurality of traction ropes 86 are connected via a connecting shaft 89, and the other ends of the connecting shaft 89 are respectively connected to two groups of support rods 82 on both sides. The two support rods 82 in each group are rotatably connected via the connecting shaft 89, so that the two support rods 82 can generate relative rotation, thereby generating rotational inertia approaching each other under the action of the tension spring, so that pressure can be generated when the friction roller 81 cleans the filter screen 64, thereby improving the cleaning effect. The other end of each traction rope 86 is connected to a winding wheel 87, and the winding wheel 87 is fixedly connected to the output shaft of the driving motor 93, so that the traction rope 86 can be rolled up by the winding wheel 87, thereby pulling the bottom plate 83 upward, which can drive the friction roller 81 to be transported upward and act on the filter screen 64.

[0028] When the present invention is in normal use, the exhaust gas after combustion carries a large amount of solid impurities and dust into different intake pipes 5, and then the electromagnetic valve controls each pair of intake pipes 5 to have only one in an open state, while the other intake pipe 5 is in a closed state, and then the exhaust gas entering the separation ring 3 enters the main pipe 1 under the combined filtering action of the filter screen 1 61 and the filter screen 2 64, and then is discharged through the high exhaust pipe;

[0029] In the above process, when the exhaust gas is filtered, since it is facing two filter screens 64, the two filter screens 64 are respectively close to itself and far away from itself, and the filter screen 64 close to itself naturally becomes the filtered surface, so the solid impurities that have not passed through will gradually cover the filter screen 64 on the filtered surface, and after the coverage is large, the exhaust gas will not be able to pass through the filter screen 64 on the filtered surface. This is because the multiple protrusions divide the space in the fixing ring 4 into multiple unconnected parts. Therefore, after the filtering capacity of the filter screen 64 facing it decreases, the exhaust gas will not be able to completely pass through the filter screen 64, so This will enter the main pipe 1 along the gap of the filter screen 1 61 in the corresponding space. At this time, the current intake pipe 5 is in a closed state through the solenoid valve switching, and the other of the paired intake pipes 5 is in an intake state. Since the other intake pipe 5 is set at a symmetrical position, the exhaust gas will also act on the filter screen 2 64 set away from itself, that is, the part where solid impurities are attached is backwashed and cleaned, and then the impurities of the filter screen 2 64 on the filtered surface are gradually accumulated. Then, the backwashing cleaning of the side can be continued by switching the intake direction, so as to dynamically keep one side of the filter screen 2 64 on both sides in a better filtered state at all times;

[0030] Since the recoil cleaning cannot remove the solid impurities in the space, the present invention is designed with a discharge component 8, which rotates the separation ring 3 and the multiple protrusions through the rotation of the rotating component 9, and opens the sealing plate. In this way, each time a protrusion is rotated to the notch 10, the solid impurities in the corresponding sealed space will be cleaned into the storage box 7, and then the drive motor 93 is started. The traction rope 86 can be tightened by the rotation of the winding wheel 87, which can drive the bottom plate 83 to drive the support rod 82 and the friction roller 81 to move upward, and the two friction rollers 81 are tightly attached to the two sides of the protrusion at the bottom under the action of the tension spring, which can effectively clean the filter screen 64, and then the collected solid impurities and dust can be discharged through the suction box, which is convenient for continuing the exhaust gas separation function after the protrusion is rotated to cooperate with the intake pipe 5.

[0031] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
