Description

Technical Field

[0002] The production process of cement includes several steps such as crushing, pre-homogenization of raw materials, sintering and grinding. Cement clinker is a semi-finished product obtained by melting and cooling limestone, clay and iron raw materials as the main raw materials in a certain proportion.

[0003] The existing patent (publication number: CN216815061U) discloses a cement clinker steady flow cooling device, including a frame, support feet installed at the lower end of the frame and symmetrically distributed on the left and right, a conveying assembly installed between the frame and another frame for conveying materials, a protective cover installed at the upper end of the frame, and an upper cooling fan fixed on the inner side of the upper end of the protective cover to cool the cement clinker.

[0004] However, in actual use, the above-mentioned prior art still has certain shortcomings. During the process of conveying cement clinker, it needs to be placed inside a container and then placed on a conveying device. However, because the cement clinker is placed inside a container, the raw materials placed inside the container will pile up together, and then be affected by the container, resulting in the raw materials at the bottom being unable to be cooled, the cooling speed will be greatly reduced, and the cooling effect is not ideal, which reduces the work efficiency of the staff and even requires secondary cooling of the raw materials at the bottom, increasing the workload of the staff and having low practicality. In view of this, we propose a cement clinker steady flow cooling device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6The utility model provides a technical solution: a cement clinker steady flow cooling device, comprising a frame 1, a cooling bin 2 is fixedly connected to the upper surface of the frame 1, the inner walls on both sides of the frame 1 and the cooling bin 2 are hollow and internally connected, a conveyor belt 3 is arranged inside the frame 1, a motor 4 is fixedly connected to the outer surface of the frame 1, the motor 4 is a self-locking motor, the output shaft of the motor 4 is fixedly connected to the transmission shaft of the conveyor belt 3, the interior of the cooling bin 2 is rotatably connected with three rotating shafts 5, both ends of the three rotating shafts 5 are rotatably penetrated into the interior of the cooling bin 2, the front rotating shaft 5 and the outer surface transmission sleeve of the rotating shaft 5 of the conveyor belt 3 are provided with a first transmission assembly 6, and the two rotating shafts 5 are connected to the cooling bin 2. The outer surface of the moving shaft 5 is provided with a second transmission assembly 7, the first transmission assembly 6 and the second transmission assembly 7 have the same structure, and are composed of two pulleys and belts. The pulleys are respectively sleeved on the outer surface of the conveyor belt 3 and the rotating shaft 5, and the outer surface of the rotating shaft 5 is fixedly connected with a flap 8. The inner wall of the cooling bin 2 is fixedly connected with three push plates 9, and the side of the push plate 9 facing the feed port is an inclined surface with an inclination angle of 10°-20°. The top of the cooling bin 2 is provided with a first cooling fan 10, and the inner walls of both sides of the cooling bin 2 are provided with a second cooling fan 11. When the staff needs to cool the cement clinker, by placing the cement clinker on the conveyor belt 3 The surface of the conveyor belt 3 is then driven by the starting motor 4 to transport the cement clinker. The front rotating shaft 5 is then driven to rotate by the cooperation of the transmission shaft of the conveyor belt 3 and the first transmission assembly 6. The three rotating shafts 5 are then rotated synchronously by the cooperation of the rotating shaft 5 and the second transmission assembly 7. The rotation of the rotating shaft 5 drives the flap 8 to rotate synchronously. At this time, the flap 8 will flip the cement clinker on the surface of the conveyor belt 3, thereby preventing the cement clinker at the bottom from being unable to be fully cooled. The push plate 9 will then contact the flipped cement clinker, and at this time, the push plate 9 will flatten the cement clinker, thereby preventing the cement clinker from piling up. The cement clinker can be cooled by the first cooling fan 10 and the second cooling fan 11 according to the accumulation situation. The above structure solves the problem that some existing steady-flow cooling devices for cement clinker have relatively low cooling efficiency and effect on cement clinker. The three rotating shafts 5 are driven to rotate by the transmission of the conveyor belt 3 to realize the turning of the cement clinker by the flap 8. Subsequently, the cement clinker is flattened by the cooperation of the push plate 9, which improves the cooling efficiency of the cement clinker and thus improves the work efficiency of the staff, reduces the cooling time of the cement clinker, improves the cooling effect, has high practicability, and at the same time improves the use efficiency of the motor 4 and reduces the cost.

[0029] Furthermore, a cleaning plate 12 is slidably sleeved on the outer surface of the flap 8, a cavity 14 is provided inside the rotating shaft 5, a cam 15 is provided inside the cavity 14, a ball groove 16 is provided on the outer surface of the cam 15, the ball groove 16 is provided along the outer surface path of the cam 15, two connecting balls 17 are movably connected inside the ball groove 16, the outer surfaces of the two connecting balls 17 are fixedly connected with connecting rods 13, the two connecting rods 13 are slidably passed through the rotating shaft 5, the two connecting rods 13 are respectively fixedly connected to the lower surfaces of the two cleaning plates 12, a driving rod 18 is provided inside the rotating shaft 5, one end of the driving rod 18 close to the cam 15 is fixedly connected to the cam 15, and the end of the driving rod 18 away from the cam 15 rotates to pass through the rotating shaft 5 and rotates to extend out of the cooling bin 2, when the flap 8 When cement clinker adheres to the surface, the staff rotates the driving rod 18 to drive the cam 15 to rotate. Since the motor 4 is a self-locking motor, the driving rod 18 will not drive the rotating shaft 5 to rotate. The rotation of the cam 15 drives the two connecting balls 17 to slide inside the ball groove 16, and the movement of the two connecting balls 17 drives the two connecting rods 13 to move. The movement of the two connecting rods 13 drives the cleaning plate 12 to slide on the surface of the flap 8, and finally the cement clinker on the surface of the flap 8 is scraped off, achieving the purpose of cleaning. The above structure is convenient for the staff to clean the flap 8, improves the cleaning efficiency of the flap 8, and is simple to operate, thereby improving the flipping efficiency of the flap 8 for cement clinker, extending the service life of the flap 8, and is highly practical.

[0030] Furthermore, a fixing ring 19 is sleeved on the outer surface of one end of the driving rod 18 located inside the cavity 14, and a torsion spring 20 is fixedly connected between the fixing ring 19 and the inner wall of the cavity 14. The torsion spring 20 is sleeved on the outer surface of the driving rod 18. Through the setting of the torsion spring 20, when the rotating shaft 5 rotates, the driving rod 18 will be driven to rotate synchronously, so that the rotating shaft 5 and the driving rod 18 are in a relatively static state, thereby ensuring the stability of the cam 15. When the driving rod 18 is rotated, the torsion spring 20 will be stretched, and the driving rod 18 can be reset subsequently by relying on the elastic force of the torsion spring 20 itself, thereby improving the use effect of the device and improving the stability of the device during operation.

[0031] Furthermore, a cooling component 21 is provided on the outside of the rack 1. The cooling component 21 is an existing structure, and its purpose is to cool the wind blown out by the first cooling fan 10 and the second cooling fan 11.
