[0002] Selective catalytic reduction (SCR) is the most widely used, efficient and mature denitrification technology, with the focus on denitrification catalysts. Denitrification catalysts are widely used in most coal-fired power plants around the world due to their wide applicable temperature range, high chemical resistance, and erosion and wear resistance.

[0024] In this embodiment, the pushing mechanism 9 includes a sliding push block 901, which is slidably connected to the supporting plate 807, and a driving motor 3 902 is fixedly connected to the sliding push block 901, and a spur gear 1 903 is fixedly connected to the output shaft of the driving motor 3 902, and a rack 1 904 is fixedly connected to the supporting plate 807, and the spur gear 1 903 is meshed with the rack 1 904.

[0025] In this embodiment, the roller-type discharging conveyor belt 11 includes a mounting frame 1101, and two of the mounting frames 1101 are symmetrically fixedly connected to the roller-type feeding conveyor belt 6. The mounting frame 1101 bracket is evenly rotatably connected to a plurality of rollers 1102, and the rollers 1102 are connected in sequence through a belt transmission assembly 1103.

[0026] In this embodiment, the transmission mechanism 10 includes a connecting bracket 1001, and the two connecting brackets 1001 are symmetrically fixedly connected to the two slide rails 201. The connecting bracket 1001 is rotatably connected to a rotating shaft 1002, and the rotating shaft 1002 is connected to one of the rollers 1102 through a belt transmission component 2 1003. The outer sides of the two slide rails 201 are rotatably connected to screw rods 3 1004, and the screw rods 3 1004 are rotatably connected to bevel gears 1005. The bevel gears 1005 and the screw rods 3 1004 are connected to a ratchet transmission component 1006, and the rotating shaft 1002 is fixedly connected to bevel gears 2 1007, and the bevel gears 1005 and 1007 are meshed.

[0027] In this embodiment, two connecting brackets 1008 are symmetrically fixedly connected to the sliding plate 202, and the connecting bracket 1008 is rotatably connected to a rotating shaft 1009, and the rotating shaft 1009 is unidirectionally rotatably connected to a spur gear 1010, and the rotating shaft 1009 is also fixedly connected to a turntable 1011, and the turntable 1011 is fixedly connected to a threaded sleeve 3 1012, and the threaded sleeve 3 1012 is opposite to the screw rod 3 1004, and the slide rail 201 is fixedly connected to a connecting bracket 3 1013, and the connecting bracket 3 1013 is fixedly connected to a rack 2 1014, and the spur gear 2 1010 will mesh with the rack 2 1014 when moving.

[0028] In this embodiment, the spur gear 1010 will mesh with the rack 1014 when moving and resetting with the sliding plate 202, so that the spur gear 1010 rotates forward and reversely by a certain angle. The one-way transmission between the spur gear 1010 and the rotating shaft 1009 ensures that the rotating shaft 1009 can be driven by the spur gear 1010 to rotate only when the denitration catalyst 5 is transported to the tray 7.

[0029] In this embodiment, each time the spur gear 2 1010 meshes with the rack 2 1014, it rotates 120 degrees. In the process of the moving mechanism 2 and the clamping mechanism 3 transporting the denitration catalyst 5 three times, the first two rotations of the spur gear 2 1010 will cause the nut sleeve 3 and the screw rod 3 1004 to be staggered, so that the nut sleeve 3 will not contact the screw rod 3 1004 during the movement. In the process of transporting the denitration catalyst 5 for the third time, the nut sleeve 3 rotates again to a position opposite to the screw rod 3 1004.

[0030] In this embodiment, only when the nut sleeve three leaves the screw rod three 1004, the rotation of the screw rod three 1004 can be transmitted to the rotating shaft one 1002 through the ratchet transmission assembly 1006, thereby driving the rotating shaft one 1002 to rotate.

[0031] When the flue gas denitration catalyst stacking and conveying device is in operation, the working process is as follows: When the push valve 1 308 abuts against the baffle 310 and is in an open state, the high-pressure gas in the high-pressure gas tank 307 enters the cavity surrounded by the flexible clip 303, the elastic side surrounding layer 304 and the installation frame 207 through the pipeline. As the pressure in the cavity increases, the flexible clip 303 is pushed inward by the gas pressure to complete the clamping of the denitration catalyst 5; The hydraulic rod 206 is retracted to lift the denitration catalyst 5, and then the driving motor 205 is driven to drive the screw rod 204 to rotate, and the sliding plate 202 is driven to move along the slide rail 201, and stops after reaching the farthest catalyst placement position on the tray 7, so that the hydraulic rod 206 is extended and stops when the catalyst contacts the tray 7. At this time, the pressing valve 2 309 is abutted against the tray 7, so that the pressing valve 2 309 is in an open state, and the high-pressure gas in the cavity is discharged from the pressing valve 2 309. Under the pulling force of the spring 302, the flexible clip 303 is separated outward to release the catalyst; Then the hydraulic rod 206 is retracted, the driving motor 205 is reversed to reset the sliding plate 202, the hydraulic rod 206 is extended again, and the above steps are repeated to continuously transport the catalyst; Each three times of transporting the catalyst is a cycle. During the first resetting process of transporting the catalyst, the drive motor 3 902 is started, driving the sliding push block 901 to move a moving distance, and then the drive motor 3 902 is turned off, thereby driving the tray 7 to move a certain distance toward the roller-type discharging conveyor 11, and at the same time, the catalyst placement point in the middle of the tray 7 is moved to the catalyst placement position at the farthest point. When the catalyst is reset for the second time, the drive motor 3 902 is started again, and the tray 7 is driven to move the same distance to the roller-type discharging conveyor 11 as before, and then the drive motor 3 902 is reversed to reset the sliding push block 901. When the catalyst is reset for the third time, the drive motor 3 902 does not move. When the catalyst is transported and reset for the third time, the nut sleeve three is removed from the screw rod three 1004, driving the screw rod three 1004 to rotate, and the screw rod three 1004 drives the rotating shaft one 1002 to rotate through the transmission component, and the rotating shaft one 1002 drives the roller 1102 to rotate through the belt transmission component two 1003, and several rollers 1102 are driven to rotate together through the belt transmission component one 1103. At this time, most of the bottom surface of the tray 7 full of catalysts has been placed on the roller type discharge conveyor belt 11, and the rotation of the roller 1102 will remove the tray 7 full of catalysts, completing the discharge; When the catalyst is transported and reset for the third time, the driving motor 806 is started, driving the screw 805 to rotate, so that the lifting bracket moves down a certain distance and then moves up to reset. When the lifting bracket moves down, the supporting plate 807 can flip upward to avoid the tray 7 on the feed conveyor belt 4. When the lifting bracket moves down, the supporting plate 807 that returns to the horizontal level will abut against the bottom surface of the tray 7, driving the tray 7 to move upward, waiting for the catalyst to be placed.
