DETAILED DESCRIPTION
[0016] The present invention is further described in detail below with reference to the accompanying drawings.
[0017] like Figure 1 , 3As shown in Figure 5, a variable speed one-way dust suction mechanism in this embodiment, the dust suction mechanism is arranged in a dust removal box, and a plurality of dust cage units arranged in parallel are arranged in the dust removal box. The dust suction mechanism includes a suction box 2, and a plurality of suction nozzles 10 are arranged on the suction box 2, and 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 arranged vertically at intervals, and the number and installation position of the suction nozzles match the dust cages in the same row. The suction box is respectively passed through one end of the suction nozzle and a suction nozzle transmission mechanism is set, 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 two trolley travel roller groups arranged symmetrically on the left and right are set on the trolley 7, and any trolley travel roller group includes two trolley travel rollers 20 arranged at intervals in front and behind. The trolley 7 is arranged in the large cart 6, and the inner wall of the large cart 6 is symmetrically provided with trolley tracks, and the trolley travel rollers 20 are arranged on the trolley tracks. The trolley driving device drives the trolley running roller 20 to move slowly forward or quickly backward along the trolley track, driving the suction box 2 and the suction nozzle 10 to move synchronously, so that the suction nozzle 10 slowly approaches the dust cage unit to suck dust, or quickly moves away from the dust cage unit, saving time to exit the dust cage unit. A fixed plate 3 is arranged on the top of the trolley 6, and a trolley running roller group is arranged on the fixed plate 3. A trolley track is set in the dust removal box body, and the trolley running roller group is arranged on the trolley track. The trolley driving device drives the trolley running roller group to move left and right along the trolley track, driving the suction box and the suction nozzle to move left and right synchronously, so that the suction nozzle unit moves to the next row of dust cage units. A suction nozzle reduction motor 9 is arranged on the upper part of the suction box 2, and multiple suction nozzles and the suction nozzle reduction motors are connected through a suction nozzle transmission mechanism. The suction nozzle reduction motor 9 drives the suction nozzle transmission mechanism to rotate unidirectionally, so that the suction nozzle 10 rotates unidirectionally synchronously. When the suction nozzle enters the dust cage unit, it performs unidirectional rotation and the suction nozzle sucks dust from the dust cage unit; when exiting the dust cage unit, the suction nozzle 10 stops rotating.
[0018] 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.
[0019] The trolley driving device includes a trolley reduction motor 5, and the trolley travel roller group includes two trolley travel rollers arranged at intervals. The trolley reduction motor 5 is connected to one trolley travel roller 11 through a first gear chain 18, and the two trolley travel rollers 11 are connected through a second gear chain transmission 19. The trolley reduction motor drives the first gear chain transmission 18 to rotate, driving one trolley travel roller 11 to move along the trolley track, and the rotation of one trolley travel roller drives the second gear chain transmission 19, so that the other trolley travel roller moves along the trolley track.
[0020] 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.
[0021] like Figure 4 As shown, the nozzle transmission mechanism includes a plurality of driven sprockets 22, which are respectively arranged at the ends of the nozzles located in the suction box, and a driving sprocket 23 is arranged on the output shaft of the nozzle reduction motor 9, and the driving sprocket 23 and the driven sprocket 22 are connected by a chain 24. When the nozzle reduction motor 9 rotates, the driving sprocket 23, the chain 24, and the driven sprocket 22 are driven to rotate unidirectionally, and then the nozzles are driven to rotate unidirectionally, so that multiple nozzles can be rotated synchronously in one direction.
[0022] A plurality of spaced limit switches 21 are provided on the trolley track, and the distance between two adjacent limit switches 21 matches the distance between two adjacent dust cage units. When the trolley moves to the limit switch, the suction nozzle corresponds to the dust cage unit at the corresponding position, and then the dust cage unit is vacuumed.
[0023] 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.
[0024] The trolley track self-cleaning device includes two symmetrically arranged air nozzles 12, fixed brackets 13 are respectively arranged on both sides of the fixed plate 3, and quick-release straight-through air pipe joints 14 are respectively arranged on the fixed brackets 13. One end of the quick-release straight-through air pipe joint 14 is connected to the air nozzle 12, and the air outlet of the air nozzle 12 is respectively facing the trolley track. The other end of the quick-release straight-through air pipe joint 14 is respectively connected to the air pipe 15, and the two air pipes 15 are connected to the air source through a three-way joint 16. When the trolley walking roller moves left and right along the trolley track, it drives the air nozzle to move left and right synchronously, and the clean gas in the air source is diverted to the two air pipes, and then sprayed to the trolley track through the two air nozzles, thereby cleaning the trolley track.
[0025] A pulse valve 17 is provided on the air source, and the pulse valve is used to control whether the air source is diverted to the two air pipes, thereby regularly cleaning the trolley track.
[0026] When the suction nozzle is close to the dust cage unit, it moves slowly (dust collection). The feeding speed of the trolley is automatically adjusted according to the dust cage resistance value under the PLC instruction. When the dust cage resistance value is between 50Pa and 300Pa, the feeding speed of the trolley is 16.5 to 9.5 mm / s, which ensures the cleaning effect and avoids nozzle blockage, and meets the adaptability of different application conditions. The suction nozzle is controlled by the nozzle reduction motor to rotate in one direction; when the suction nozzle is away from the dust cage unit, it moves quickly (exit), the nozzle reduction motor stops, the trolley reduction motor reverses and the trolley exit speed is 54 mm / s. After the exit setting time is reached, the trolley exit speed drops to 16.5 mm / s and stops after reaching the original position, which ensures the stability of the dust collection mechanism and shortens the dust collection cycle.
[0027] The trolley drive device drives the trolley to move left and right along the trolley track. The movement of the trolley drives the suction nozzle to remove dust from different rows of dust cage units. The trolley drive device drives the trolley to move forward and backward in the trolley. It moves slowly when approaching the dust cage unit and quickly when away from the dust cage unit, thereby reducing the time to exit the dust cage unit, reducing the dust cleaning cycle, and improving the dust handling capacity. The suction nozzle is controlled by the nozzle reduction motor to rotate in one direction, avoiding plush filter material and increasing the service life of the dust cage filter bag.
[0028] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
