Description

Technical Field

[0001] The invention relates to the technical field of cement transportation, and in particular to a cement lifting and transportation device for cement production. Background Art

[0002] Cement production is a vital link in the construction industry, and the transportation efficiency and environmental performance of cement are directly related to the overall performance and sustainability of the production line. As a key equipment connecting different production processes, the main function of cement lifting and conveying device is to transport cement from a low position to a high position to meet the needs of subsequent processes, such as storage, batching or packaging. In the existing cement production line, bucket elevators have become the main equipment in cement lifting operations due to their simple structure, easy maintenance and strong adaptability. Bucket elevators continuously lift materials in a vertical or inclined direction through a series of buckets fixed on traction chains or belts. Its advantages include large conveying capacity, flexible lifting height, stable and reliable operation, and relatively low energy consumption. It is very suitable for conveying materials such as cement that are highly abrasive and have a high specific gravity.

[0003] However, although bucket elevators are widely used in cement transportation, there are still some technical difficulties, especially when transporting powdered materials such as cement. Since cement particles are small and have a certain viscosity, when they are stationary in the hopper, they are easily accumulated or agglomerated at the bottom and edge of the hopper due to their own gravity and mutual squeezing. This phenomenon not only reduces the effective volume of the hopper, resulting in a decrease in the actual amount of cement transported in each lifting cycle, reducing the transportation efficiency; in addition, during the throwing process, the high-speed released cement particles will generate a large impact force, causing dust in the air to fly, which not only causes pollution to the working environment, but also may pose a threat to the health of workers, while also increasing the cost and complexity of subsequent dust removal treatment.

[0025] like Figure 2-Figure 3 , Figure 5-Figure 6 , Fig.14As shown, as an embodiment, in order to clean the filter screen on the side of the lower end of the shell 1, a driving wheel 14 is also arranged on one side of the lower end of the shell 1, and the driving wheel 14 is also fixed on a movable shaft 31. The movable shaft 31 is provided with a multi-prism-shaped anti-rotation rod at one end close to the lower rotating shaft 19, and a first guide groove 20 corresponding to and adapted to the anti-rotation rod is provided on one side of the lower rotating shaft 19. The anti-rotation rod is movably guided and cooperated with the first guide groove 20. Annular grooves 33 are provided on both sides of the driving wheel 14, and depressions 12 are evenly provided on the inner wall of the annular groove 33. Bosses are formed between adjacent depressions 12, and the depressions 12 on one side of the driving wheel 14 correspond to the bosses on the other side. A fixing frame 18 is provided on the side wall of the lower end of the shell 1, and the fixing frame 18 extends from one end away from the shell 1 to the side of the driving wheel 14 facing away from the shell 1. The side wall of the lower end of the shell 1 and the end of the fixing frame 18 away from the shell 1 are respectively provided with the driving wheel 14. The fixing rods 28 corresponding to the two sides have one end movably connected with the annular groove 33, and the fixing rod 28 is rotatably provided with a roller 29 on one end of the fixing rod 28 located inside the annular groove 33. The second traction arm 13 is rotatably provided with the one end of the movable shaft 31 away from the rotating shaft 19, and the second traction arm 13 is movably connected with the first guide rod 15 corresponding to the second traction arm 13 on one side of the lower end of the shell 1.

When the driving wheel 14 below rotates, it also moves back and forth, thereby driving the second traction arm 13 to move. The second traction arm 13 drives the brush plate 23 to move back and forth through the first guide rod 15, and the brush plate 23 can clean the filter screen on the side surface of the lower end of the shell 1 to avoid blockage. The bottom of the inner cavity of the shell 1 is an arc-shaped depression. When cement accumulates at the bottom of the inner cavity of the shell 1, the hopper 22 can shovel up the cement again when it passes by.

[0026] When in use, the driving source 5 drives the synchronous wheel 25 to rotate through the rotating shaft 19, and the synchronous wheel 25 drives the synchronous belt 21 to operate, and the synchronous belt 21 drives the hopper 22 to operate synchronously, and the hopper 22 passing through is loaded through the feeding port 2. When the hopper 22 runs to the upper end of the inner cavity of the shell 1, the cement will be thrown out, and then fall into the discharge port 3 for discharge, and when the rotating shaft 19 rotates, it will drive the driving wheel 14 to rotate through the movable shaft 31. Since the spacing between the corresponding two fixed rods 28 remains unchanged, as the driving wheel 14 rotates, the roller 29 will push the inner wall of the recess 12 or the boss under the action of the recess 12 and the boss in the annular groove 33, so that the driving wheel 14 rotates and moves back and forth, and the displacement of the driving wheel 14 will drive the displacement of the third traction arm 30, and the third traction arm 30 will drive the displacement of the extrusion plate 24 through the second guide rod 17. When the extrusion plate 24 moves inward, it will squeeze the passing force plate 34, and during this period, the ball 32 can reduce friction. When the force plate 34 is squeezed, the third guide rod 35 will be driven to move inward, the elastic member 36 will be compressed, and the third guide rod 35 will drive the guide shaft 39 to move. Under the action of the second guide groove 38, the extrusion plate 37 will move toward the direction of the connecting port 43, and then the air in the corner of the cavity 40 will be squeezed, and the air will enter the arc-shaped air guide cover 44 through the connecting port 43. Under the guidance of the inner wall of the arc-shaped air guide cover 44, the airflow will be swept along the inner wall of the hopper 22 through the purge port 45, so that the cement accumulated and attached to the inner wall of the hopper 22 can be blown away. When the extrusion disc 24 is separated from the force plate 34, the elastic member 36 is reset, and then the extrusion plate 37 is reset. The first vent 41 and the second vent 42 are convenient for air inlet and outlet when the extrusion plate 37 is displaced, and the purge port 45, the first vent 41, and the second vent 42 are all provided with filter screens to prevent cement from entering the cavity 40, and when the extrusion plate 37 is displaced toward the filter screen, the filter screen will be backblown to avoid blockage. In addition, in order to reduce the dust raised in the discharge port 3 area, when the driving wheel 14 rotates, it will also drive the driven wheel 16 to rotate, and the driven wheel 16 will drive the fan blades 27 to rotate through the fan shaft 26. The fan blades 27 generate negative pressure in the fan cover 6, the bellows 10, and the dust removal pipe 9, and then the raised dust is absorbed by the absorption port 47, and then enters the bellows 10, and then returns to the inner cavity of the shell 1 through the negative pressure pipe 11, the fan cover 6, and the return pipe 7. The gas can be discharged through the filter screen on the side of the lower end of the shell 1, and the cement is blocked inside the shell 1. When the dust removal pipe 9 is reset, the first traction arm 8 will be driven to move synchronously, so the first traction arm 8 will drive the dust removal pipe 9 to reset through the slider 46, and while the dust removal pipe 9 is reset, the dust removal pipe 9 will also rotate due to the engagement of the gear 48 and the rack 49, so the position and direction of the absorption port 47 are constantly adjusted, thereby increasing the dust removal effect. When the dust removal pipe 9 is displaced, the slide plate 50 is displaced on the inside of the bellows 10, and the width of the slide plate 50 is greater than the width of the side opening of the bellows 10. Therefore, when the slide plate 50 is reset, the opening position can always be blocked, thereby preventing cement from leaking out again.
