DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 、 3As shown in Figure 5, a variable-speed one-way dust suction mechanism in this embodiment is provided in the dust removal box body, and a plurality of dust cage units arranged in parallel are provided in the dust removal box body. The dust suction mechanism includes a suction box 2, on which a plurality of suction nozzles 10 are provided. The plurality of suction nozzles 10 are evenly spaced vertically along the suction box 2. The dust cage unit includes a plurality of dust cages spaced vertically, and the number and installation position of the suction nozzles match the dust cages in the same row. One end of the suction nozzle is respectively penetrated by the suction box and a suction nozzle transmission mechanism is provided, and the other end of the suction nozzle is arranged tilted downward. The top of the suction box is fixed to the bottom of the trolley 7 by bolts, and the trolley 7 is provided with two symmetrically arranged trolley travel roller groups. Any trolley travel roller group includes two trolley travel rollers 20 spaced front to back. The trolley 7 is provided in the carriage 6, and the inner wall of the carriage 6 is symmetrically provided with trolley tracks, and the trolley travel rollers 20 are provided on the trolley tracks. The trolley drive mechanism drives the trolley rollers 20 along the trolley track, moving them forward or backward at a slow speed. This drives the suction box 2 and the suction nozzles 10 to move synchronously, allowing the nozzles 10 to slowly approach the dust cage unit for dust collection or quickly move away from the unit, saving time when exiting the unit. A fixed plate 3 is mounted on the top of the trolley 6, on which a trolley roller assembly is mounted. A trolley track is provided within the dust removal unit, and the trolley roller assembly is mounted on the trolley track. The trolley drive mechanism drives the trolley roller assembly left and right along the track, driving the suction box and the suction nozzles to move synchronously left and right, allowing the nozzle units to move to the next row of dust cage units. A nozzle reduction motor 9 is mounted above the suction box 2. Multiple suction nozzles are connected to the nozzle reduction motor via a nozzle transmission mechanism. The nozzle reduction motor 9 drives the nozzle transmission mechanism to rotate unidirectionally, causing the suction nozzles 10 to rotate synchronously. When the suction nozzles enter the dust cage unit, they rotate unidirectionally, collecting dust from the unit. When they exit the unit, the suction nozzles 10 stop rotating.

[0023] A suction box interface 1 is provided at the bottom of the suction box 2, and the suction box interface 1 is connected to a subsequent dust collecting fan so that the collected dust in the suction box is discharged to a subsequent device.

[0024] The trolley drive device includes a trolley reduction motor 5, and a trolley travel roller assembly comprising two spaced-apart trolley travel rollers. The trolley reduction motor 5 is connected to one trolley travel roller 11 via a first gear chain 18, and the two trolley travel rollers 11 are connected via a second gear chain 19. The trolley reduction motor drives the first gear chain 18 to rotate, driving one trolley travel roller 11 along the trolley track. The rotation of one trolley travel roller drives the second gear chain 19, causing the other trolley travel roller to move along the trolley track.

[0025] The trolley driving device includes a trolley reduction motor 8. The trolley travel rollers on the same side are connected by a belt. The trolley reduction motor drives one trolley travel roller group to rotate, driving the belt and the other trolley travel roller group to rotate.

[0026] like Figure 4 As shown, the nozzle transmission mechanism includes multiple driven sprockets 22, which are respectively arranged at the ends of the nozzles located in the suction box. A driving sprocket 23 is provided on the output shaft of the nozzle reduction motor 9. The driving sprocket 23 and the driven sprocket 22 are connected by a chain 24. When the nozzle reduction motor 9 rotates, it drives the driving sprocket 23, the chain 24, and the driven sprocket 22 to rotate unidirectionally, thereby driving the nozzles to rotate unidirectionally, thereby achieving synchronous unidirectional rotation of multiple nozzles.

[0027] The trolley track is provided with a plurality of spaced limit switches 21, and the distance between two adjacent limit switches 21 matches the distance between two adjacent dust cage units. When the trolley moves to a limit switch, the suction nozzle corresponds to the dust cage unit at the corresponding position, and then the dust cage unit is vacuumed.

[0028] like Figure 2 As shown, a trolley track self-cleaning device is also provided on the fixed plate 3, and the trolley track self-cleaning device performs self-cleaning on the trolley track.

[0029] The trolley track self-cleaning device includes two symmetrically arranged air nozzles 12. Fixed brackets 13 are provided on either side of the fixed plate 3. Quick-release straight-through air pipe connectors 14 are provided on the fixed brackets 13. One end of the quick-release straight-through air pipe connector 14 is connected to the air nozzle 12, and the air outlet of the air nozzle 12 faces the trolley track. The other end of the quick-release straight-through air pipe connector 14 is connected to an air pipe 15. The two air pipes 15 are connected to the air source via a three-way connector 16. When the trolley running roller moves left and right along the trolley track, it drives the air nozzle to move synchronously left and right. The clean gas in the air source is diverted into the two air pipes and then sprayed onto the trolley track through the two air nozzles, thereby cleaning the trolley track.

[0030] A pulse valve 17 is provided on the air source, which is used to control whether the air source is diverted to the two air pipes, thereby regularly cleaning the trolley track.

[0031] When the nozzle approaches the dust cage unit, it moves slowly (dust collection). The trolley feed speed is automatically adjusted according to the dust cage resistance value under PLC instructions. When the dust cage resistance value is between 50Pa and 300Pa, the trolley feed speed is 16.5 to 9.5mm / s, ensuring cleaning results and preventing nozzle clogging, meeting adaptability to different application conditions. The nozzle is controlled by the nozzle reduction motor to rotate unidirectionally. When the nozzle moves away from the dust cage unit, it moves rapidly (exit), the nozzle reduction motor stops, the trolley reduction motor reverses, and the trolley exits at a speed of 54mm / s. After the set exit time is reached, the trolley exit speed drops to 16.5mm / s and stops at its original position, ensuring the stability of the dust collection mechanism and shortening the dust collection cycle.

[0032] The trolley drive mechanism propels the trolley left and right along the trolley track, driving the suction nozzles to remove dust from different rows of dust cage units. The trolley drive mechanism propels the trolley forward and backward within the trolley, moving slowly when approaching a dust cage unit and rapidly away from it. This reduces the time it takes to exit the unit, shortens the cleaning cycle, and improves dust handling capacity. The suction nozzles, controlled by a nozzle reduction motor, rotate unidirectionally, preventing the formation of lint in the filter media and extending the life of the dust cage filter bags.

[0033] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
