DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figures 1 to 5 The embodiment of the present application provides a pulverizing device for efficiently grinding blast furnace granulated slag powder, including a frame 1 and a pulverizer 2. The frame 1 is provided with an inclined screen 3. The output end of the pulverizer 2 is located above the screen 3. An elastic vibration mechanism is installed on the frame 1, and the elastic vibration mechanism is connected to the screen 3. A conveyor 4 is installed on the frame 1. The conveyor 4 can be a belt conveyor whose motor is a servo motor. A square sleeve 5 is installed on the conveyor 4. An extrusion block 6 is slidably connected in the square sleeve 5. The extrusion block 6 is provided with a chamfer. A force sensor 27 is installed in the square sleeve 5. The force sensor 27 can be a pressure sensor. A spring 7 is installed on the force sensor 27. The output end of the spring 7 is connected to the pressure sensor 27. The extrusion block 6 is connected, and the extrusion block 6 is arranged in cooperation with the screen 3. Support sleeves 8 are installed at both ends of the extrusion block 6. A support sleeve shaft 9 is slidably clamped in the support sleeve 8. A spring 2 10 is installed in the support sleeve 8. The output end of the spring 2 10 is connected to the support sleeve shaft 9. Extension grooves 11 are provided on both sides of the frame 1. The support sleeve shaft 9 can extend out of the frame 1 from the extension grooves 11. Chamfers are provided on both sides of the support sleeve shaft 9. A linear drive device 12 is installed on the frame 1. The linear drive device 12 can be an electric slide. A slide seat 13 is installed at the output end of the linear drive device 12. A linear actuator 14 is installed on the slide seat 13. The linear actuator 14 can be an electric cylinder. The linear actuator 14 is arranged in cooperation with the support sleeve shaft 9.

[0022] In this embodiment, the slag crushed by the crusher 2 falls onto the screen 3, and the elastic vibration mechanism drives the screen 3 to vibrate and screen. When the elastic vibration mechanism drives the screen 3 to vibrate, the impact of the falling slag on the screen 3 causes the vibration of the screen 3 to be irregular. The conveyor 4 drives the extrusion block 6 sliding in the square sleeve 5 to squeeze and remove the slag stuck in the screen 3, and the spring 17 always squeezes the extrusion block 6, so that the extrusion block 6 can always contact the lower surface of the screen 3. Due to the inclined setting of the screen 3, when the conveyor 4 drives the extrusion block 6 from the lower end of the screen 3 to the higher end of the screen 3, the cleaning effect is better. Therefore, a chamfer is set at the upper corner of the extrusion block 6. When the extrusion block 6 squeezes the spring 17 at the same position for many times, the force sensor 27 can record the signal, so that the linear actuator 14 on the slide 13 installed at its output end is driven by the linear drive device 12 to move to the specified position, and the conveyor 4 drives the extrusion block 6 After moving to the same position, it stops rotating, and the support sleeve shaft 9 squeezed out by the spring 2 10 in the support sleeve 8 on both sides of the extrusion block 6 extends from the extension groove 11 on the frame 1, so that the output end of the linear actuator 14 can squeeze the extended end of the support sleeve shaft 9 multiple times, and finally the extrusion block 6 can remove the slag that is stuck relatively firmly in the screen 3; the chamfering setting on both sides of the support sleeve 9 enables it to be squeezed back into the support sleeve 8 through the chamfering when it moves to the edge of the extension groove 11; when the linear actuator 14 squeezes and lifts the support sleeve shaft 9 multiple times, it can cooperate with the indication of the force sensor 27 to detect the height of the extrusion block 6 and the support sleeve shaft 9, so that the extrusion lifting height of the linear actuator 14 can be adjusted.

[0023] In some embodiments, in order to achieve the vibration screening effect of the screen 3, an elastic vibration mechanism is provided, including a sleeve 15 and a sleeve 2 16. A sleeve 17 is slidably connected inside the sleeve 15, and the output end of the sleeve 17 is connected to one side of the screen 3. A spring 3 18 is installed inside the sleeve 15, and one end of the spring 3 18 is connected to the sleeve 17. A sleeve 2 19 is slidably connected inside the sleeve 2 16, and the output end of the sleeve 2 19 is connected to the side of the screen 3 away from the sleeve 17. A spring 4 20 is installed inside the sleeve 2 16, and the output end of the spring 4 20 is connected to the sleeve 2 19. The sleeve 17 and the sleeve 2 19 are connected by a connecting rod 21. The tilting effect of the screen 3 is achieved by sleeve shaft 17 and sleeve shaft 2 19 sliding in sleeve shaft 1 15 and sleeve shaft 2 16 of different lengths. At the same time, through the pulling effect of spring three 18 and spring four 20 on sleeve shaft 17 and sleeve shaft 2 19, when the screen 3 is impacted and lowered by slag, it can be pulled back by spring three 18 and spring four 20 through sleeve shaft 17 and sleeve shaft 2 19 respectively; in order to improve the linkage between sleeve shaft 17 and sleeve shaft 2 19 and avoid greater damage to spring three 18 close to the output end of the crusher 2, sleeve shaft 17 and sleeve shaft 2 19 are connected together by a connecting rod 21, so that various parts of the screen 3 can be raised and lowered synchronously.

[0024] In some embodiments, in order to allow the slag to be screened through the hole portion of the screen 3 instead of falling directly from the two sides of the screen 3, guide plates 22 are installed on both sides of the screen 3.

[0025] In some embodiments, in order to improve the supporting effect on the square sleeve 5 squeezed downward by the squeezing block 6, support grooves 23 are provided on both sides of the frame 1, and support columns 24 are installed on both sides of the square sleeve 5, and the support columns 24 slide in the support grooves 23.
