DETAILED DESCRIPTION

[0019] 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.

[0020] In order to solve the problem that in the existing cement grinding equipment, all large and small particles of cement are thrown into the equipment together during the grinding process, and the larger particles of cement need to be repeatedly transmitted through the spiral blades, causing the spiral blades to bear a large workload during the operation of the entire equipment, affecting the smoothness of the equipment during use, this embodiment provides the following technical solutions:

[0021] A cement grinding device for cement production includes a second fixed frame 7, one side of the second fixed frame 7 is fixedly connected to a vibration motor by bolts, and an upper end of one side of the second fixed frame 7 is provided with a storage box 1, such as Figure 1 As shown, when the cement processing material is crushed, the powder material is put in from the storage box 1, and a first transmission tube 3 is transversely arranged at the lower end of the storage box 1, and the first transmission tube 3 is sealed and connected to the storage box 1. The powder material put into the storage box 1 will fall into the first transmission tube 3 due to gravity, and different sizes of diversion are realized in the first transmission tube 3;

[0022] In this embodiment, a first filter screen 11 is disposed on one side of the lower end of the first transmission pipe 3, and a material drop opening 10 penetrating into the first transmission pipe 3 is disposed on the other side of the lower end of the first transmission pipe 3. Figure 2 and Figure 3 As shown, the processing material with larger particles falls into the second fixed frame 7 from the drop opening 10, while the processing material with smaller particles passes through the first filter screen 11 and falls. A first screw rod 8 is transversely arranged inside the first transmission tube 3. The first screw rod 8 can push the particle material falling from the storage box 1 after the motor output. After the particle material is pushed by the first screw rod 8, the particle can contact the first filter screen 11 and move toward the drop opening 10, so that the processing material is diverted during the falling process.

[0023] In this embodiment, the upper and lower ends of the second fixed frame 7 are provided with crushing rollers 14, the lower end of the crushing roller 14 at the upper end of the second fixed frame 7 is provided with a second filter 15, and the lower end of the crushing roller 14 at the lower end of the second fixed frame 7 is provided with a third filter 16. The granular material crushed by the crushing roller 14 needs to be additionally filtered by the second filter 15 and the third filter 16 before it can fall. Figure 2 As shown, a second screw rod 9 is disposed on the other side of the upper end of the second fixed frame 7. The particles restricted by the second filter screen 15 and the third filter screen 16 will move toward the second screw rod 9. The second filter screen 15 and the third filter screen 16 are inclined toward the second screw rod 9. The material with the same size of particles can be refluxed through the transmission of the second screw rod 9 and contact the crushing roller 14 again.

[0024] In this embodiment, a second transmission pipe 4 is disposed outside the second spiral rod 9, and a second connecting pipe 6 for connecting is disposed on one side of the second transmission pipe 4 facing the second filter screen 15 and the third filter screen 16, and both ends of the second connecting pipe 6 are sealedly connected to the second transmission pipe 4 and the second fixing frame 7, respectively. Figure 2 and Figure 4As shown, the connection position of the second connecting pipe 6 and the second fixing frame 7 is located at the upper end of one side of the second filter screen 15 and the third filter screen 16, and the particulate material restricted by the second filter screen 15 and the third filter screen 16 will fall into the second transmission pipe 4 through the second connecting pipe 6;

[0025] In this embodiment, a first fixing frame 2 is disposed at the lower end of the first filter screen 11, and the first fixing frame 2 is fixed to the first transmission pipe 3 by welding. Figure 1 and Figure 2 As shown, a guide cavity 17 is provided inside the first fixed frame 2, and the lower end of the guide cavity 17 is sealed and connected to the upper end of one side of the crushing roller 14 at the lower end of the second fixed frame 7. The particle material passing through the first filter screen 11 can be directly crushed by the crushing roller 14 through the transmission of the guide cavity 17, and the small particle material does not need to be filtered by the second filter screen 15, thereby reducing unnecessary crushing process and improving crushing efficiency.

[0026] In this embodiment, a first connecting pipe 5 is provided at an upper end of one side of the outer side of the second transmission pipe 4 toward an upper end of the second fixing frame 7, and the first connecting pipe 5 is sealed and connected to the second transmission pipe 4. Figure 1 and Figure 2 As shown, the material transmitted by the second screw rod 9 will be transported again to the inside of the second fixed frame 7 by the first connecting pipe 5. The mesh number of the third filter screen 16 is larger than that of the second filter screen 15, and the mesh number of the second filter screen 15 is larger than that of the first filter screen 11. After filtering in sequence, the material falling from the position of the third filter screen 16 can meet the requirements of grinding.

[0027] Working principle: When the device is used and the cement raw material processing material is ground, the granular material is put into the storage box 1, put into and fall into the first transmission pipe 3, and the first screw rod 8 rotates after being output. The rotation of the first screw rod 8 can push the falling granular material and push the particles to move toward the drop port 10. During the movement, the smaller particles will pass through the first filter screen 11 and fall into the guide cavity 17, and then enter the second fixed frame 7 after flowing into the guide cavity 17, while the larger particles will fall through the drop port 10, fall into the second fixed frame 7, and fall. The material entering the second fixed frame 7 will contact the rotating crushing roller 14 for crushing, and the crushed material will contact the second filter screen 15 and the third filter screen 16 respectively. The material that has not passed through the second filter screen 15 and the third filter screen 16 will move toward the second spiral rod 9. The rotation of the second spiral rod 9 can push the contacted granular material, so that the granular material moves longitudinally upward in the second transmission pipe 4, and then moves and is transported from the first connecting pipe 5 to the second fixed frame 7 again. The granular material of qualified size will pass through the second filter screen 15 and the third filter screen 16 in turn and then be discharged.
