Description

Technical Field

[0001] This utility model relates to the technical field of cement production, specifically to a clinker feeding device. Background Technology

[0002] Cement clinker is a semi-finished product made by mixing limestone, clay, and iron raw materials in appropriate proportions to form raw meal, burning it until it is partially or completely melted, and then cooling it. It is mostly in block form and is usually stored in cement storage silos. When discharging, it is discharged through hoppers.

[0003] A clinker feeding device for cement production and processing, disclosed in publication number CN210752968U, includes: a feeding section for outputting crushed cement clinker; a conveying mechanism disposed within a housing, the conveying mechanism including a belt and a drive roller, the belt being tensioned to the drive roller, the feeding section being connected to the housing above the belt; one end of an extraction pipe connected to the upper end face of the housing, and the other end connected to an extraction device, a filter element fixedly disposed at one end of the extraction pipe; and a rapping mechanism including a rapping rod, a cam, a top plate, and a push rod, the cam being coaxially connected to the drive roller, the top plate abutting against the upper edge of the cam, one end of the push rod being rotatably connected to the top plate, the other end being rotatably connected to one end of the rapping rod, the other end of the rapping rod contacting the filter element, and the middle part of the rapping rod being rotatably connected to the housing.

[0004] The aforementioned document describes the use of pulverizing and dust removal equipment for clinker crushing and dust control. However, since cement itself requires a powdery form, the clinker cement powder is also discharged during the pulverizing process along with the air extraction, which leads to a reduction in the amount of clinker fed and affects the conveying effect. In addition, the aforementioned document uses a simple rotary pulverizing method, which has a poor crushing effect on cement clinker. Furthermore, the clinker enters the hopper and accumulates inside due to its overall weight, causing it to be discharged quickly and affecting the feeding effect. Therefore, we propose a clinker feeding device to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a clinker feeding device, including a feeding hopper 1, a drive motor 6, and a protective frame 17. Mounting plates 2 are fixed to the lower front and rear sides of the feeding hopper 1. A first rotating roller shaft 3 is rotatably connected to the lower left end of the feeding hopper 1. The first rotating roller shaft 3 is connected to a second connecting shaft 9 via a second conveyor belt 31, enabling the second connecting shaft 9 to drive the first rotating roller shaft 3 for material conveying via the conveyor belt 5. A second transmission roller shaft 4 is rotatably connected to the end of the mounting plate 2, and a conveyor belt 5 is provided between the first rotating roller shaft 3 and the second transmission roller shaft 4. The drive motor 6 is fixed to one side below the surface of the feeding hopper 1. The output end of the drive motor 6 is fixedly connected to a first connecting shaft 7 rotatably connected inside the hopper 1. A first rotating drum 8 is fixedly fixed to the surface of the first connecting shaft 7. A second connecting shaft 9 is rotatably connected to the lower side of the hopper 1 away from the first connecting shaft 7. A second rotating drum 10 is fixedly fixed to the surface of the second connecting shaft 9. Crushing blades 11 are evenly fixed to the surfaces of the first rotating drum 8 and the second rotating drum 10. The crushing blades 11 on the surface of the first rotating drum 8 and the crushing blades 11 on the surface of the second rotating drum 10 are staggered to facilitate the use of the two sets of staggered crushing blades 11 for crushing cement clinker.

[0026] Please see Figure 1-5A first gear 12 is fixed to the end of the first connecting shaft 7 on the outside of the hopper 1. A second gear 13, meshing with the first gear 12, is fixed to the end of the second connecting shaft 9. A rotating shaft 14 is rotatably connected above the first gear 12 and the second gear 13 on the surface of the hopper 1. A cam 15 is fixed to the surface of the rotating shaft 14. The first connecting shaft 7 and the rotating shaft 14 are connected by a first conveyor belt 16. A protective frame 17 is fixed to the outside of the hopper 1. A movable block 18 is slidably connected above the protective frame 17. The movable block 18 is T-shaped, and its lower end face fits against the upper end face of the cam 15 to facilitate the convexity of the hopper. When the wheel 15 rotates, it presses the movable block 18 to move. An opening 19 is provided in the middle of the surface of the hopper 1. A horizontal plate 20 is welded to the middle of the movable block 18. The upper and lower ends of the horizontal plate 20 are connected to the upper and lower ends of the opening 19 on the surface of the hopper 1 by springs 21. The upper and lower ends of the inner surface of the horizontal plate 20 are fixed with baffles 22 with a width greater than the width of the opening 19, so that the horizontal plate 20 can bounce up and down under the action of the spring 21. At the same time, with the use of the baffles 22, cement clinker is prevented from entering the opening 19. Side plates 23 are welded to both ends of the horizontal plate 20, and the side plates 23 are bent. Pins 24 are welded at equal intervals on the upper surfaces of the horizontal plate 20 and the side plates 23. The use of the pins 24 on the surface of the horizontal plate 20 and the side plates 23 can facilitate the crushing of the cement clinker accumulated inside the hopper 1, avoiding the problem of cement clinker being difficult to discharge.

[0027] Please see Figure 1-5 A dust suppression component is installed on the side of the feeding hopper 1, located on one side of the conveyor belt 5. The dust suppression component includes a water supply tank 25, which is fixed to the lower side of the feeding hopper 1. A water pump 26 is installed on the upper side of the water supply tank 25. One end of the water pump 26 is connected to the bottom of the water supply tank 25 through a water suction pipe 27. The other end of the water pump 26 is connected to a drain pipe 28. The end of the drain pipe 28 is connected to a water collection pipe 29 fixed to the side of the feeding hopper 1. Atomizing nozzles 30 are evenly installed below the water collection pipe 29 to facilitate the reduction of overflowing cement dust through the atomizing nozzles 30, thus avoiding the problem of cement dust overflow and waste.

[0028] Working principle: First, when in use, the drive motor 6 is turned on, which drives the first connecting shaft 7 to rotate, thereby causing the first rotating roller 8 on its surface to rotate. The first gear 12 at the end of the first connecting shaft 7 will mesh with the second gear 13 at the end of the second connecting shaft 9, so that the second rotating roller 10 on the surface of the second connecting shaft 9 will rotate in opposite directions. With the use of the crushing blades 11 that are alternately arranged on the surfaces of the first rotating roller 8 and the second rotating roller 10, it is convenient to crush the discharged cement clinker, and the crushed cement clinker will fall onto the clinker belt 5 for the cement clinker feeding work.

[0029] When the first connecting shaft 7 rotates, it drives the rotating shaft 14 to rotate via the first conveyor belt 16, so that the cam 15 on the surface of the rotating shaft 14 rotates synchronously. When the cam 15 rotates, it drives the horizontal plate 20 to move upward inside the hopper 1. With the use of the springs 21 at the upper and lower ends of the horizontal plate 20, the horizontal plate 20 can slide up and down in the hopper 1. The two ends of the surface of the horizontal plate 20 are fixed with side plates 23. When the horizontal plate 20 moves up and down, the pins 24 on the surface of the horizontal plate 20 and the side plates 23 can crush the cement clinker accumulated inside the hopper 1, so that the cement clinker can be discharged.

[0030] During clinker feeding, the water pump 26 on the dust suppression assembly can be turned on, allowing the water pump 26 to draw water from the water supply tank 25 into the water collection pipe 29 through the water suction pipe 27 and the drain pipe 28. This facilitates the use of the atomizing nozzle 30 below the water collection pipe 29 to reduce the overflowing cement dust, preventing dust from scattering and causing cement waste. This is the operating principle of the clinker feeding device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
