Description
Technical Field
[0001] This utility model relates to the field of building materials machinery technology, specifically to a high-efficiency cement grinding equipment. Background Technology
[0002] Cement grinding is the "last mile" in the cement production process and a core link that determines the quality of finished cement products (fineness, specific surface area, uniformity), production energy consumption, and overall cost. The technological evolution of cement grinding equipment has always revolved around the four core needs of "quality improvement, energy saving, cost reduction, and environmental protection." Its development background is deeply linked to the industrial upgrading, energy policies, environmental protection requirements, and technological breakthroughs of the cement industry.
[0003] In the cement production process, the efficiency of the grinding system directly affects the cement production quality and output. The feeding method of the circulating bucket elevator into the V-separator is not reasonable, usually with single or few channels, resulting in uneven distribution of material entering the V-separator and uneven thickness of the material curtain, which affects the separation effect of the V-separator and prevents qualified fine powder from being fully selected, thus reducing the efficiency of the entire grinding system. On the other hand, the lack of an effective homogenization device in the upper part of the intermediate silo of the roller press makes it easy for material to segregate when entering the intermediate silo. The uneven distribution of large and small particles leads to poor compression effect of the roller press on the material, which not only affects the grinding efficiency but also increases energy consumption. Therefore, a high-efficiency cement grinding equipment is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency cement grinding equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency cement grinding equipment includes a fixed frame, a connecting pipe fixedly connected to the inner side of the fixed frame, a feed pipe fixedly connected to the top of the connecting pipe, a V-shaped chute fixedly connected to the top of the feed pipe, a first homogenizing plate fixedly connected to the inner side of the connecting pipe, a first homogenizing hole formed at the top of the first homogenizing plate, a V-shaped material separator chute fixedly connected to the bottom of the connecting pipe, symmetrically arranged support plates fixedly connected to both sides of the fixed frame, an electric telescopic rod fixedly connected to the front side of the support plate, a rubber pad fixedly connected to the front end of the electric telescopic rod, and a material separator located at the first homogenizing plate fixedly connected to the inner side of the connecting pipe. A second homogenizing plate is located at the top of the plate, and a second homogenizing hole is formed at the top of the second homogenizing plate. A third homogenizing plate is fixedly connected to the inner side of the connecting pipe at the top of the second homogenizing plate, and a third homogenizing hole is formed at the top of the third homogenizing plate. A fourth homogenizing plate is fixedly connected to the inner side of the connecting pipe at the top of the third homogenizing plate, and a fourth homogenizing hole is formed at the top of the fourth homogenizing plate. A fifth homogenizing plate is fixedly connected to the inner side of the connecting pipe at the top of the fourth homogenizing plate, and a fifth homogenizing hole is formed at the top of the fifth homogenizing plate. A sixth homogenizing plate is fixedly connected to the inner side of the connecting pipe at the top of the fifth homogenizing plate, and a sixth homogenizing hole is formed at the top of the sixth homogenizing plate.
[0006] Preferably, the shapes of the first homogenizing plate, the second homogenizing plate, the third homogenizing plate, the fourth homogenizing plate, the fifth homogenizing plate, and the sixth homogenizing plate are matched, and the outer dimensions of the first homogenizing plate, the second homogenizing plate, the third homogenizing plate, the fourth homogenizing plate, the fifth homogenizing plate, and the sixth homogenizing plate are matched with the inner dimensions of the connecting pipe.
[0007] Preferably, the first, second, third, fourth, fifth, and sixth homogenizing holes are matched in shape and are all circular holes. The inner diameters of the first, second, third, fourth, fifth, and sixth homogenizing holes are arranged sequentially from bottom to top, with each layer having a larger diameter than the last.
[0008] Preferably, four of the electric telescopic rods are evenly spaced on the surface of the support plate. The four electric telescopic rods, the rubber pad, and the support plate form a group, and there are two groups in total. They are symmetrically arranged on the upper and lower sides of the fixed frame.
[0009] Preferably, the connecting pipe, the first homogenizing plate, the second homogenizing plate, the third homogenizing plate, the fourth homogenizing plate, the fifth homogenizing plate, the sixth homogenizing plate, the first homogenizing hole, the second homogenizing hole, the third homogenizing hole, the fourth homogenizing hole, the fifth homogenizing hole, and the sixth homogenizing hole are arranged in a close fit and are uniformly arranged between the feed pipe and the V-shaped separator chute.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up components such as a V-shaped chute, connecting pipe, feed pipe, and V-shaped separator chute, the material is evenly fed through a four-channel connecting pipe, so that the material can form a uniform material curtain when entering the V-shaped separator chute. This ensures that the material distribution in each area of the V-shaped separator chute is consistent, thereby improving the sorting accuracy and efficiency of the V-shaped separator. This allows qualified fine powder to be selected more fully and enter subsequent processes. This solves the problem in cement production where the efficiency of the grinding system directly affects the production quality and output of cement. The feeding method of the circulating bucket elevator into the V-separator chute is not reasonable. Usually, it is a single channel or a few channels for feeding, which leads to uneven distribution of material entering the V-separator and uneven thickness of the material curtain, affecting the sorting effect of the V-separator. As a result, qualified fine powder cannot be fully selected, reducing the efficiency of the entire grinding system. 2. In this utility model, through the components such as the first homogenizing plate, the first homogenizing hole, the second homogenizing plate, the second homogenizing hole, the support plate, the electric telescopic rod, and the rubber pad, the material is continuously dispersed and mixed during its descent through the homogenizing holes in the center of multiple sets of homogenizing plates. Since the homogenizing holes on the homogenizing plates gradually decrease in size from top to bottom, the material is fully homogenized, and large and small particles are fully homogenized. The homogenized material enters the intermediate silo along a path concentric with the intermediate silo, making the material distribution in the intermediate silo uniform and avoiding segregation. In this way, when the roller press squeezes the material, it can be subjected to uniform force, improve the squeezing effect, and reduce energy consumption. The electric telescopic rod and the rubber pad can continuously strike the connecting pipe, forming a vibration effect, further improving the throughput efficiency of cement powder. This solves the problem that, on the other hand, the upper part of the intermediate silo of the roller press lacks an effective homogenization device, and the material is prone to segregation when entering the intermediate silo, resulting in uneven distribution of large and small particles, which leads to poor squeezing effect of the roller press, affecting grinding efficiency and increasing energy consumption.

[0016] Please see Figure 1-3 This utility model provides a technical solution: A high-efficiency cement grinding equipment includes a fixed frame 1, a connecting pipe 2 fixedly connected to the inner side of the fixed frame 1, a feed pipe 3 connected to the top of the connecting pipe 2, a V-shaped chute 4 fixedly connected to the top of the feed pipe 3, a first homogenizing plate 5 fixedly connected to the inner side of the connecting pipe 2, a first homogenizing hole 6 opened at the top of the first homogenizing plate 5, a V-shaped material separator chute 7 connected to the bottom of the connecting pipe 2, symmetrically arranged support plates 8 fixedly connected to both sides of the fixed frame 1, an electric telescopic rod 9 fixedly connected to the front side of the support plate 8, a rubber pad 10 fixedly connected to the front end of the electric telescopic rod 9, and a second homogenizing plate 11 located at the top of the first homogenizing plate 5 fixedly connected to the inner side of the connecting pipe 2.

The top end of the third homogenizing plate 13 has a third homogenizing hole 14. The inner side of the connecting pipe 2 is fixedly connected to a fourth homogenizing plate 15 located at the top end of the third homogenizing plate 13. The top end of the fourth homogenizing plate 15 has a fourth homogenizing hole 16. The inner side of the connecting pipe 2 is fixedly connected to a fifth homogenizing plate 17 located at the top end of the fourth homogenizing plate 15.

The inner side of the connecting pipe 2 is fixedly connected to a sixth homogenizing plate 19 located at the top end of the fifth homogenizing plate 17. The top end of the sixth homogenizing plate 19 has a sixth homogenizing hole 20.
[0017] The shapes of the first homogenizing plate 5, the second homogenizing plate 11, the third homogenizing plate 13, the fourth homogenizing plate 15, the fifth homogenizing plate 17, and the sixth homogenizing plate 19 are matched. The outer dimensions of the first homogenizing plate 5, the second homogenizing plate 11, the third homogenizing plate 13, the fourth homogenizing plate 15, the fifth homogenizing plate 17, and the sixth homogenizing plate 19 match the inner dimensions of the connecting pipe 2, which can effectively ensure that all cement powder passes through the central homogenizing hole structure; the first homogenizing hole 6, the second homogenizing hole 12... The third homogenizing hole 14, the fourth homogenizing hole 16, the fifth homogenizing hole 18, and the sixth homogenizing hole 20 are matched in shape, all being circular holes. The inner diameters of the first homogenizing hole 6, the second homogenizing hole 12, the third homogenizing hole 14, the fourth homogenizing hole 16, the fifth homogenizing hole 18, and the sixth homogenizing hole 20 are arranged sequentially from bottom to top, with each layer having a larger diameter than the previous one. This effectively improves the uniformity of the cement powder and prevents segregation when it enters the lower structure. Four electric telescopic rods 9 are evenly spaced on the surface of the support plate 8. Four electric telescopic rods 9, rubber pads 10, and one support plate 8 form a group, with two groups in total. These groups are symmetrically arranged on the upper and lower sides of the fixed frame 1, which can more efficiently achieve the vibration effect and accelerate the passage of cement powder. The connecting pipe 2, the first homogenizing plate 5, the second homogenizing plate 11, the third homogenizing plate 13, the fourth homogenizing plate 15, the fifth homogenizing plate 17, the sixth homogenizing plate 19, the first homogenizing hole 6, the second homogenizing hole 12, and the third homogenizing hole 10 are all included. 4. The fourth homogenizing hole 16, the fifth homogenizing hole 18 and the sixth homogenizing hole 20 are grouped together, and there are four groups in total. The connecting pipe 2, the first homogenizing plate 5, the second homogenizing plate 11, the third homogenizing plate 13, the fourth homogenizing plate 15, the fifth homogenizing plate 17 and the sixth homogenizing plate 19, the first homogenizing hole 6, the second homogenizing hole 12, the third homogenizing hole 14, the fourth homogenizing hole 16, the fifth homogenizing hole 18 and the sixth homogenizing hole 20 are evenly arranged in a close fit between the feed pipe 3 and the V-shaped sorting machine chute 7.
[0018] Workflow: When using a high-efficiency cement grinding equipment, the entire system is powered externally. First, cement powder is poured into the V-shaped chute 4 through the circulating hopper. The V-shaped chute 4 guides the cement, increasing its falling speed. The powder then enters the four connecting pipes 2 through the feed pipe 3. The powder then passes through the first homogenizing plate 5, first homogenizing hole 6, second homogenizing plate 11, second homogenizing hole 12, third homogenizing plate 13, third homogenizing hole 14, fourth homogenizing plate 15, fourth homogenizing hole 16, fifth homogenizing plate 17, fifth homogenizing hole 18, sixth homogenizing plate 19, and the fourth homogenizing hole 16. The six homogenization holes 20, because the homogenization holes on the homogenization plate gradually decrease in size from top to bottom, the material will be continuously dispersed and mixed during the falling process, and large and small particles will be fully homogenized. The homogenized material enters the intermediate silo along a path concentric with the intermediate silo, so that the material distribution in the intermediate silo is uniform and segregation is avoided. The electric telescopic rod 9 and the rubber pad 10 can continuously strike the connecting pipe 2 to form a vibration effect, further improving the throughput efficiency of cement powder. Finally, it enters the intermediate silo through the V-type material classifier chute 7 to complete the collection.
