Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, and specifically relates to a high-efficiency and energy-saving cement roller press roller surface structure. Background Technology

[0002] Cement roller presses, also known as extrusion mills, roller mills, or double roller mills, are a new type of energy-saving cement grinding equipment developed internationally in the mid-1980s. They can replace the energy-intensive and inefficient ball mill pre-grinding system, reducing steel consumption and operating noise. Suitable for new plant construction and also for upgrading existing plants, they can increase system output by 30-50%. After extrusion, the material contains 20-35% fine particles of 0.08mm and 65-85% particles smaller than 2mm. The internal structure of the particles is filled with tiny cracks due to extrusion, greatly improving grindability. The roller surface uses hot-welded overlay, making the wear-resistant layer easy to maintain. However, the distance between the rollers cannot be adjusted, resulting in low flexibility, inefficiency, and energy saving. During the rolling process, the material usually concentrates in the middle of the roller surface, causing uneven wear. When replacement is needed, the surface condition at both ends is still relatively good. To solve the problems mentioned above, we propose a high-efficiency and energy-saving cement roller press roller surface structure. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency and energy-saving roller surface structure for a cement roller press, which has the advantages of adjustable powder particle size and uniform feeding.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency and energy-saving cement roller press roller surface structure, including a base plate, a fixing plate bolted to the left side of the top of the base plate, a support plate A bolted to the front and rear ends of the top of the fixing plate near the middle, a roller rod A rotatably connected to the opposite sides of the two support plates A, and the front end of the surface of the roller rod A passing through the front of the front support plate A, a roller surface A fixedly sleeved to the rear end of the surface of the roller rod A, a support rod A bolted to the edges of the two corners of the front end of the top of the base plate, a rotating rod rotatably connected to the opposite sides of the two support rods A, and the left side of the rotating rod passing through the left side of the left support rod A, a spline provided at the rear end of the surface of the rotating rod, a key sleeve threadedly connected to the surface of the spline, a transmission mechanism provided at the front end of the surface of the rotating rod, and a feeding mechanism provided at the top of the support plate A.

[0005] The above technical solution involves the rotation of the rotating rod driving the rotation of roller A, which in turn drives the rotation of roller surface A. The rotation of the rotating rod drives the rotation of the spline, which in turn drives the rotation of the key sleeve. The key sleeve can move on the spline to adapt to the production of cement of different strength grades. Through precise adjustment of the roller spacing, the two rollers rotate relative to each other, resulting in higher compaction efficiency and more uniform particle size. The cement roller press has comprehensive advantages in terms of energy saving, increased production, quality control, and equipment durability, meeting the high-efficiency and low-carbon requirements of modern cement production. By increasing the spacing between the rollers according to the required cement strength grade, the total power consumption of the system can be reduced.

[0006] The present invention is further configured such that the feeding mechanism includes a feeding box, the feeding box is bolted to the top of the support plate A, and the support plate B is bolted to the front and rear ends of the bottom right side of the feeding box. A bracket is bolted to the middle of the bottom inside the feeding box. A balance plate is rotatably connected to the front and rear ends of the inner side of the support plate. A baffle is bolted to the middle of the top of the balance plate. A spring is bolted to the front and rear ends of the bottom of the balance plate, and the bottom of the spring is bolted to the front and rear ends of the bottom inside the feeding box near the middle. The two sides of the bottom inside the feeding box away from the middle are provided with a discharge port.

[0007] The above technical solution employs a feeding mechanism. During feeding, the material falls onto the balance plate, which rotates with the weight of the material on both sides. The spring at one end contracts under pressure, causing the material to fall into the feed inlet. The other end of the balance plate tilts towards this end due to the pressure, and the spring rebounds, providing a rebound force before the material is discharged. This ensures that the material is discharged as evenly as possible from both ends. During feeding, the material is evenly distributed on both ends of the roller surface. During the rolling process at both ends, the material at the top is squeezed and vibrated to the middle of the roller surface. Even rolling avoids local overload on the roller surface, extends the roller surface life, and reduces the frequency of downtime and repair due to roller surface damage.

[0008] The present invention is further configured such that the transmission mechanism includes a vertical bevel gear A, which is fixedly sleeved at the front end of the rotating rod surface; a horizontal bevel gear A is fixedly sleeved on the front side of the roller A, and the left side of the horizontal bevel gear A meshes with the back side of the vertical bevel gear A; a vertical bevel gear B is fixedly sleeved on the left end of the key sleeve surface; a support rod B is rotatably sleeved on the right end of the key sleeve surface; a horizontal bevel gear B meshes with the back side of the vertical bevel gear B; a roller B is fixedly sleeved inside the horizontal bevel gear B; a support plate B is rotatably connected to the front end and back side of the roller B surface; a roller surface B is fixedly sleeved on the rear end of the roller B surface; a movable plate is bolted to the bottom of the support plate B, and the front end of the top of the movable plate is bolted to the bottom of the support rod B; a motor A is fixedly sleeved on the left side of the rotating rod, and the right side of the motor A body is bolted to the left side of the left support rod A; a threaded sleeve is bolted to the rear end of the top of the movable plate, and a screw is threadedly connected inside the threaded sleeve; a motor B is fixedly sleeved on the right side of the screw.

[0009] The above technical solution employs a transmission mechanism. When motor A rotates, a rotating rod rotates, which in turn drives vertical bevel gears A and B to rotate, which in turn drives horizontal bevel gears A and B to rotate. The vertical bevel gears A and B rotate in opposite directions, as do the horizontal bevel gears A and B. The horizontal bevel gears A and B then drive rollers A and B to rotate, which in turn drive roller surfaces A and B to rotate. Motor B drives a screw to rotate, which in turn drives a screw sleeve to move, thus moving a movable plate. The rotating rod drives a spline to rotate, which in turn drives a key sleeve to rotate. The movable plate moves along the spline, allowing adjustment of the distance between the roller surfaces.

[0010] The present invention is further configured such that a sliding groove is provided in the middle of the top right side of the base plate, and a slider is bolted to the bottom of the movable plate, and the surface of the slider is slidably connected to the inside of the sliding groove.

[0011] The above technical solution uses a sliding groove and a slider to limit the movement of the moving plate.

[0012] The present invention is further configured such that a discharge port is provided through the middle of the top of the base plate, and a feed port is provided through the top of the feed box.

[0013] The above technical solution allows for both material discharge and feeding by setting up an outlet and an inlet.

[0014] The present invention is further configured such that a leak-proof plate is bolted to the right side of the support plate A.

[0015] The above technical solution, by setting up a leak-proof plate, can prevent leakage to other places.

[0016] The present invention is further configured such that a limiting rod is rotatably connected to the left side of the screw, and the bottom of the limiting rod is bolted to the rear end of the top of the fixing plate away from the middle.

[0017] The above technical solution uses a limiting rod to stabilize the screw.

[0018] The present invention is further configured such that the bottom of the motor B is bolted to a frame, and the bottom of the frame is bolted to the corner of the top right rear end of the base plate.

[0019] The above technical solution involves setting up a frame to stabilize motor B.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model adapts to the production of cement of different strength grades. Through precise adjustment of the roller spacing, the two rollers rotate relative to each other, resulting in higher compaction efficiency and more uniform particle size.

The spacing between the rollers can be increased according to the strength grade of cement to be produced, thereby reducing the total power consumption of the system.

[0022] 2. This utility model distributes the material evenly at both ends of the roller surface during feeding.
