Description

Technical Field

[0001] The utility model relates to the technical field of clinker bulk machines, in particular to a dust collecting device for a clinker bulk machine. Background Art

[0002] A clinker bulk loader is a device used to evenly distribute clinker onto transport vehicles. Its structure primarily includes a feeding system, a conveying system, a bulk loading head, a support structure, and a control system. This equipment is primarily used for loading clinker from cement plants to trucks or ships. It features automatic positioning, automatic tracking of material level detection, low energy consumption, smooth unloading, large loading capacity, and dust-free loading and shipping. However, when bulking cargo, a conveyor bulk loader sometimes contains a large amount of dust. Due to national standards for dust emissions, the equipment must absorb the dust during bulk loading to prevent dust splashing. However, existing equipment, which may contain large foreign matter in the clinker, typically uses filter plates to filter out large particles during the adsorption process to prevent damage to the vacuum pump. However, due to the high pressure of the vacuum pump, dust easily accumulates on the filter surface, reducing the permeability of the filter plates.

[0003] Based on this, the utility model designs a clinker bulk loader dust collecting device to solve the above problems. Utility Model Content

[0021] See also Figures 1-4 , the utility model provides a technical solution:

[0022] A dust collecting device for a clinker bulk loader comprises a material pipe 1, a bulk head 2 is provided on the inner side of the material pipe 1, a mounting plate 3 is installed between the material pipe 1 and the bulk head 2, a filter plate 4 for dust filtering is installed between the material pipe 1 and the bulk head 2, a negative pressure chamber is formed between the filter plate 4 and the mounting plate 3, a gear ring 5 is rotatably connected in the negative pressure chamber, a lifting mechanism 6 is installed on the gear ring 5, a fixing frame 11 is fixedly connected to the lifting mechanism 6, a cleaning mechanism 12 for cleaning the filter plate 4 is installed on the fixing frame 11, a driving mechanism 17 for driving the gear ring 5 to rotate is provided on the mounting plate 3, a negative pressure machine 20 is installed on the material pipe 1, and one end of the negative pressure machine 20 is connected through the negative pressure chamber.

[0023] Among them, the lifting mechanism 6 includes a slide rod 7, a spring 8, an auxiliary wheel 9 and a track plate 10. The slide rod 7 is slidably connected to the gear ring 5, and a spring 8 is sleeved on the slide rod 7. An auxiliary wheel 9 is installed at one end of the slide rod 7, and a track plate 10 is installed in the negative pressure chamber. The auxiliary wheel 9 is movably connected to the track plate 10; it is convenient to control the cleaning mechanism 12 to lift, thereby vibrating the filter plate 4 to avoid foreign matter being stuck in the filter plate 4, thereby affecting its filtration.

[0024] Among them, a plurality of grooves are opened on the track plate 10, and the sides of the grooves are wedge-shaped; this is convenient for improving the vibration convenience of the equipment, making the equipment more efficient and more effective when vibrating.

[0025] Among them, the cleaning mechanism 12 includes a rotating shaft 13, a torsion spring 14, a cleaning roller 15 and a hammer block 16. The rotating shaft 13 is rotatably connected to the fixed frame 11, and a torsion spring 14 is sleeved on the rotating shaft 13. A cleaning roller 15 is installed on the rotating shaft 13, and two hammer blocks 16 are installed on the fixed frame 11. The hammer block 16 is located in front of the cleaning roller 15; it is convenient to clean the filter plate 4, thereby effectively ensuring the filtering efficiency of the filter plate 4 and preventing foreign matter from being stuck in the through hole of the filter plate 4.

[0026] Among them, the driving mechanism 17 includes a driving motor 18 and a gear 19. The driving motor 18 is installed on the mounting plate 3. The gear 19 is installed on the output end of the driving motor 18. The gear 19 is meshed with the gear ring 5; it effectively controls the operation of the equipment and ensures its quality and effect during filtration.

[0027] Working principle: During operation, when the bulk head 2 moves to a suitable position, the expansion and contraction of the material tube 1 is controlled, so that the gap between the bulk head 2 and the loading bottom becomes smaller, which facilitates the adsorption of dust and reduces the splashing of dust. Then the negative pressure machine 20 is controlled to work. When the negative pressure machine 20 is working, the negative pressure machine 20 adsorbs the gas through the negative pressure chamber. At this time, the dust is sucked out through the filter plate 4 and the drive motor 18 is turned on at the same time. The drive motor 18 drives the gear ring 5 to rotate through the gear 19. When the gear ring 5 rotates, the gear ring 5 drives the lifting mechanism 6 and the cleaning mechanism 12 to move, thereby ensuring the cleanliness of the filter plate 4. When the lifting mechanism 6 moves, the auxiliary wheel 9 moves on the track plate 10. Since a plurality of grooves are provided on the track plate 10 and the side edges of the grooves are wedge-shaped, when the auxiliary wheel 9 moves up along the wedge , the spring 8 is stretched, and the fixing frame 11 moves up. At this time, the distance between the hammer block 16 and the filter plate 4 is stretched, and due to the action of the torsion spring 14, the cleaning roller 15 is always in contact with the filter plate 4, thereby fully cleaning the filter plate 4, thereby ensuring the cleanliness of the filter plate 4. When the auxiliary wheel 9 falls from the wedge shape, the spring 8 rebounds, and then the hammer block 16 hammers on the filter plate 4, causing the filter plate 4 to vibrate, thereby effectively destroying the static balance between the accumulated dust in the filter holes of the filter plate, so that the dust is shaken off and smoothly passes through the filter plate to be collected, further ensuring the air permeability of the through holes of the filter plate 4 in the equipment, and avoiding the foreign matter being sucked into the filter plate 4 due to the excessive negative pressure of the negative compressor 20 during the use of the filter plate 4, thereby affecting the dust collecting effect of the equipment.
