DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Referring to Figure 1 and Figure 2 , the utility model provides an embodiment: a vertical mill feeding transmission structure for cement production, including material frame 1, material frame 1 one side fixed connection has support frame 2, support frame 2 one side fixed connection has hollow column 3, material frame 1 inside is set with feed inlet 9, hollow column 3 inside is provided with grinding assembly, and material frame 1 one side is provided with connecting assembly;

[0031] The grinding assembly comprises a rotating rod 5 rotatably connected inside the hollow column 3, and the outer wall of the rotating rod 5 is fixedly connected with spiral blades 6, which can effectively grind the cement particles during the conveying process. The inclination angle of the spiral blades 6 is designed to be a moderate angle, so that during rotation, not only the material can be pushed, but also enough friction can be generated to achieve a preliminary grinding effect. The hollow column 3 is fixedly connected with a hopper 7 inside. The support frame 2 is fixedly connected with a motor 4 on one side. The output end of the motor 4 is connected with the rotating rod 5. One end of the hollow column 3 is fixedly connected with a discharge hopper 8.

[0032] Specifically, when using the vertical mill feeding and conveying structure, first, the cement is poured into the hopper 7 by manual or mechanical means. The design of the hopper 7 allows the cement to flow orderly into the hollow column 3 below. At this time, the output end of the motor 4 is connected with the rotating rod 5. The driving force of the motor 4 is transmitted through the rotating rod 5 to drive the rotating rod 5 to start rotating. The outer wall of the rotating rod 5 is fixedly connected with spiral blades 6. The shape of the spiral blades 6 is spiral, and a proper inclination angle is designed. During the rotation of the spiral blades 6, the cement is continuously pushed by the pushing force of the spiral blades 6, and at the same time, it is also accompanied by a certain grinding effect. During the rotation of the spiral blades 6, the cement is pushed along the axial direction of the hollow column 3 through the structure and rotation of the spiral blades 6, thereby realizing the conveying function of the cement. At the same time, due to the shape design of the spiral blades 6, the cement particles will collide and rub with each other, achieving a preliminary grinding effect. After the cement is conveyed by the spiral blades 6, it finally falls into the material frame 1 through the discharge hopper 8 at one end of the hollow column 3, completing the conveying process of the cement.

[0033] Referring to Figure 1 and Figure 3 , the connecting assembly comprises a fixed frame 12 and a rotating block 13. The fixed frame 12 is fixedly connected on one side of the material frame 1. The rotating block 13 is rotatably connected inside the fixed frame 12. The bottom of the rotating block 13 is fixedly connected with an electric push rod 14, which is used to drive the movement of the connecting frame 15. The output end of the electric push rod 14 is fixedly connected with the connecting frame 15. The connecting frame 15 is rotatably connected with a transmission column 16 inside. The transmission column 16 is slidingly connected inside the sliding groove 19. The rotation of the rotating column 17 cooperates with the screen 20, so that the material can be classified and screened through the screen 20 during the rotation. The rotating column 17 is rotatably connected inside the material frame 1. One end of the rotating column 17 is fixedly connected with a connecting rod 18. The outer wall of the rotating column 17 is fixedly connected with the screen 20. The purpose is to preliminarily screen the cement material and remove oversized particles or impurities. The connecting rod 18 is provided with a sliding groove 19 inside. The transmission column 16 is slidingly connected inside the sliding groove 19. The material frame 1 is provided with a discharge opening one 10 inside. The material frame 1 is provided with a discharge opening two 11 inside. The material frame 1 is fixedly connected with a guide plate 21 inside.

[0034] Specifically, when the cement enters the inside of the material frame 1, the electric push rod 14 starts to work, the work of the electric push rod 14 makes the connecting frame 15 move, the connecting frame 15 is stressed, and the internal transmission column 16 is driven to slide along the sliding groove 19 in the inside of the material frame 1. The design of the sliding groove 19 makes the transmission column 16 keep stable movement in the process of cement flowing, avoiding the phenomenon of jamming. The other end of the transmission column 16 is connected with the connecting rod 18, and the other end of the connecting rod 18 is connected with the rotating column 17. The rotating column 17 starts to rotate through the transmission relationship with the connecting rod 18 after being pushed by external force. The outer wall of the rotating column 17 is fixed with the screen 20. The rotation of the screen 20 is driven by the rotating column 17, so that the screen 20 rotates in the inside of the material frame 1, and the shape and aperture size of the screen 20 are used to screen the cement. The rotation of the screen 20 makes the cement particles in it classified according to particle size. The larger particles remain on the screen 20, and the smaller particles fall through the holes of the screen 20. The screened cement forms a certain accumulation layer above the screen 20. Through the inclination angle of the screen 20, the larger part of the cement particles gradually slides to the lower side of the screen 20, is discharged through the discharge port two 11, and enters the next processing link. The smaller cement particles screened out through the screen 20 fall along the holes of the screen 20, enter the discharge port one 10, and are finally discharged.

[0035] Working principle: when the vertical mill feeding and conveying structure is used, the cement is first poured into the hopper 7 and falls into the inside of the hollow column 3. At this time, the rotating rod 5 is driven to rotate by the output end of the motor 4, so that the rotating rod 5 drives the spiral blade 6 connected to the outer wall to rotate in the inside of the hollow column 3. Through the shape of the spiral blade 6, the spiral blade 6 conveys and grinds the cement in the rotating process. Finally, the cement falls into the inside of the material frame 1 through the discharge hopper 8 at one end of the hollow column 3, so as to effectively grind and convey the cement. When the cement enters the inside of the material frame 1, the connecting frame 15 can be moved by the output end of the electric push rod 14. The connecting frame 15 drives the internal transmission column 16 to slide in the inside of the sliding groove 19, so that the connecting rod 18 drives the rotating column 17 on one side to rotate in the inside of the material frame 1. The rotating column 17 is stressed, drives the screen 20 connected to the outer wall to rotate in the inside of the material frame 1, so that the screen 20 is resisted on one side of the material frame 1, and the cement falls above the screen 20 for screening. The screened cement is discharged from the discharge port one 10, and the cement not subjected to screening remains above the screen 20 and slides through the inclination of the screen 20, so as to be discharged from the discharge port two 11, thereby effectively screening the cement.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
