Technical Field

[0001] This utility model relates to the field of building materials, and more specifically, to a vertical mill for processing cement clinker and slag. Background Technology

[0002] In the construction industry, the processing of cement clinker and slag has always been a critical step. Traditional cement clinker and slag processing equipment often lacks an effective material pretreatment mechanism before the grinding process. The previous feed pipe structure was simple and did not have a dedicated crushing device inside, which caused large pieces of cement clinker and slag to enter the grinding area directly. This required the grinding equipment to consume a lot of energy to crush these large pieces of material, resulting in low grinding efficiency, severe equipment wear, and extremely high energy consumption.

[0003] Therefore, a vertical mill is proposed to address the above problems for processing cement clinker and slag. Utility Model Content

[0026] Example 1

[0027] Please see Figs. 1-3A vertical mill for processing cement clinker and slag includes a housing 1. A first feed pipe 18 and a second feed pipe 26 are fixedly connected to the upper part of the housing 1. The second feed pipe 26 communicates with the upper part of the housing 1. Crushing rollers 27 are rotatably connected inside both the first and second feed pipes 18. An inclined plate 24 is fixedly connected to the lower part of the first feed pipe 18. A guide plate 25 is fixedly connected to the lower part of the first feed pipe 18, communicating with the first feed pipe 18. The lower part of the inclined plate 24 is located on one side of the guide plate 25. One end of the conveyor is fixedly connected to a conveyor cylinder 2. The top end of the conveyor cylinder 2 passes through the outer wall of the first feed pipe 18 and is located inside the first feed pipe 18. The inside of the conveyor cylinder 2 is rotatably connected to a spiral conveyor roller 21. The bottom of the conveyor cylinder 2 is fixedly connected to a second motor 22. The output end of the second motor 22 is fixedly connected to one end of the spiral conveyor roller 21. The top of the conveyor cylinder 2 is fixedly connected to a discharge pipe 23. The end of the discharge pipe 23 passes through the first feed pipe 18 and is located inside the second feed pipe 26. The end of the discharge pipe 23 is located above the crushing roller 27 inside the second feed pipe 26.

[0028] In this embodiment, a No. 1 feed pipe 18 and a No. 2 feed pipe 26 are provided above the box 1, and both are rotatably connected to a crushing roller 27. This design can perform initial crushing of cement clinker and live slag. Before the material enters the main grinding area, large pieces of material are pre-crushed into smaller particles, which greatly improves the efficiency of subsequent grinding processes. Taking common cement clinker and live slag as examples, after pre-treatment by the crushing roller 27, a lot of time and energy are saved for subsequent grinding.

[0029] The inclined plate 24 at the bottom inside the No. 1 feed pipe 18 works in conjunction with the guide plate 25 at the bottom outside. The inclined plate 24 guides the material after being crushed by the crushing roller 27 to the guide plate 25. Since the inclined plate 24 is made of wear-resistant alloy material and has an optimized tilt angle, it can ensure that the material slides smoothly, avoids material accumulation and blockage, and ensures the continuity of the feeding process. The guide plate 25 is connected to the No. 1 feed pipe 18, which makes the material transition smooth and further improves the reliability of feeding.

[0030] The conveying cylinder 2 and its internal spiral conveying roller 21, connected to one end of the guide plate 25, together with the drive of the second motor 22, form a highly efficient material conveying system. The variable pitch design of the spiral conveying roller 21, with a small blade spacing at the feeding end, can generate a large pushing force to quickly suck the material into the conveying cylinder 2; the increased blade spacing at the discharge end allows the material to be output smoothly, avoiding excessive crushing or blockage of the material due to squeezing and collision during the conveying process. This design allows the material conveying capacity to be flexibly adjusted according to the motor speed. In actual production, it can greatly improve the adaptability of the equipment to different production requirements according to different production needs.

[0031] The feed pipe 23 above the conveying cylinder 2 passes through the first feed pipe 18 and is located inside the second feed pipe 26 and above the crushing roller 27. This structure ingeniously realizes the secondary distribution of materials. It accurately sends the materials conveyed by the conveying cylinder 2 into the crushing area of ​​the second feed pipe 26, making the materials more evenly distributed during the secondary crushing process, further improving the crushing effect and effectively improving product quality.

[0032] Example 2,

[0033] Please see Figs. 1-3 A vertical mill for processing cement clinker and slag includes a rotating shaft 13 rotatably connected inside the housing 1, a No. 1 motor 12 fixedly connected to the bottom of the housing 1, the output end of the No. 1 motor 12 fixedly connected to the bottom of the rotating shaft 13, a grinding block 14 fixedly connected to the outer wall of the rotating shaft 13, a guide platform 16 fixedly connected inside the housing 1, the grinding block 14 located in the middle of the guide platform 16, a fixing frame 15 fixedly connected inside the housing 1, the top of the rotating shaft 13 rotatably connected to the top of the fixing frame 15, a discharge gate 17 rotatably connected to the bottom of the outer wall of the housing 1, and a support foot 11 fixedly connected to the bottom of the housing 1.

[0034] In this embodiment, the No. 1 motor 12 connected to the bottom of the housing 1 is firmly connected to the bottom of the rotating shaft 13 through a rigid coupling, which can efficiently and stably transmit power to the rotating shaft 13. The motor has an overload protection function, which greatly reduces the risk of equipment damage caused by abnormal load and effectively extends the service life of the equipment. Its speed adjustment function can flexibly adjust the speed of the rotating shaft 13 according to the material characteristics and production needs, thereby improving grinding efficiency.

[0035] The superhard alloy grinding block 14 fixed on the outer wall of the rotating shaft 13 is treated with a special process, resulting in excellent hardness and wear resistance. Its unique trapezoidal or conical design, combined with the optimized distribution density and angle on the rotating shaft 13, can perform all-round, efficient and uniform grinding of materials during rotation, significantly improving product quality.

[0036] The guide platform 16 inside the housing 1 has a smooth surface and a wear-resistant coating. Its tilt angle and shape are carefully designed to accurately guide the flow of materials, so that the materials can fully contact the grinding block 14 located in the middle, avoid material accumulation, and improve grinding efficiency.

[0037] The fixed frame 15 is welded from high-strength steel, which has strong rigidity and stability. The upper part of the rotating shaft 13 is rotatably connected to the fixed frame 15 through a matching bearing, which can effectively bear the axial and radial loads when the rotating shaft 13 rotates at high speed, ensuring the smooth operation of the rotating shaft 13 and reducing equipment vibration and wear.

[0038] The discharge door 17 on the lower part of the outer wall of the box 1 is connected by a hinge, which makes it easy to open and close. The sealing strip on the door effectively prevents material leakage. The cast iron support feet 11 at the bottom of the box 1 are equipped with shock-absorbing pads.

[0039] Working principle: Cement clinker and live slag enter the equipment through feed pipe 18 and feed pipe 26 respectively. Inside the feed pipe, the rotating crushing roller 27 performs initial crushing on the material. The high-strength alloy steel rotating shaft of the crushing roller 27 ensures stable operation under high load. The special serrated or corrugated texture on the surface improves crushing efficiency. After crushing, the material slides down the inclined plate 24 in feed pipe 18 and falls precisely into guide plate 25. Guide plate 25 is tightly connected to feed pipe 18 to ensure smooth material transition, and the minimal gap between guide plate 25 and inclined plate 24 prevents material leakage.

[0040] When the conveying cylinder 2 connected to one end of the guide plate 25 starts working, the second motor 22 is started, and its output end drives the spiral conveying roller 21 to rotate. The variable pitch spiral blades of the spiral conveying roller 21 have a small gap at the feeding end, generating a strong pushing force to quickly suck the material into the conveying cylinder 2; the gap gradually increases at the discharge end, so that the material is output smoothly. After being conveyed by the conveying cylinder 2, the material passes through the upper discharge pipe 23, passes through the first feed pipe 18 and enters the second feed pipe 26, and falls precisely into the second feed pipe 26 above the crushing roller 27, realizing the secondary distribution of the material.

[0041] Inside the housing 1, motor 12 starts, and its output end is rigidly connected to shaft 13 via a coupling, providing stable power to shaft 13. Both ends of shaft 13 are rotatably connected to bearing seats at the top and bottom of housing 1 via high-precision, high-load-bearing self-aligning roller bearings, ensuring that it can adapt to force changes during high-speed rotation. The superhard alloy grinding block 14 fixed on the outer wall of shaft 13 rotates at high speed to grind the material. The grinding block 14 is treated with special heat treatment and grinding process, and has extremely high hardness and wear resistance. Its trapezoidal or conical design and optimized distribution density and angle on shaft 13 make grinding more efficient and uniform. At the same time, the guide platform 16 with a smooth wear-resistant coating on the inner surface of housing 1 guides the flow of material, ensuring that the material fully contacts the grinding block 14 located in the middle, improving the grinding effect. The fixing frame 15 is welded from high-strength steel, and its upper part is rotatably connected to shaft 13 via bearings that can withstand axial and radial loads, enhancing the stability of shaft 13 rotation.

[0042] The ground material reaches the bottom of the box 1. At this time, the discharge door 17, which is connected to the lower part of the outer wall of the box 1, is opened. The sealing strip on the discharge door 17 prevents material leakage during equipment operation. After opening, the material is discharged smoothly. The support feet 11 at the bottom of the box 1 are made of high-strength cast iron and have shock-absorbing pads at the bottom. They effectively reduce vibration and noise during equipment operation, ensure stable operation of the equipment, and provide reliable support for the entire working process.

[0043] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
