Description

Technical Field

[0001] This utility model relates to the field of cement processing technology, and specifically to a cement roller pressing device. Background Technology

[0002] Cement grinding is the final and most energy-intensive step in cement manufacturing. Its main function is to grind cement clinker (along with retarders and performance modifiers) to a suitable particle size (expressed as fineness, specific surface area, etc.), forming a specific particle size distribution, increasing its hydration surface area, accelerating the hydration rate, and meeting the requirements for cement paste setting and hardening. With the increasingly sophisticated development of precalciner kilns, the heat consumption of clinker production has significantly decreased, while the overall electricity consumption of cement production has remained persistently high. In the cement manufacturing industry, cement raw materials are typically in powder form. The production of these powdered materials usually involves crushing larger particles using a double-roller cement roller press.

[0003] Currently, the double-roller cement roller press used for cement roller pressing can achieve the roller pressing and crushing of cement blocks through the counter-rotation of the rollers. However, on the one hand, because the rollers are fixedly installed in the shell inside the device, after the rollers wear down after long-term continuous operation, the entire roller press needs to be disassembled before the worn parts of the roller surface can be repaired and maintained. The entire disassembly process of the roller press is quite cumbersome, resulting in low efficiency of roller surface repair and maintenance. On the other hand, during the cement roller pressing process, cement particles are prone to accumulate at the feeding pipe, causing blockages and resulting in low feeding efficiency of cement particles, which is not conducive to the efficient roller pressing of cement particles. Utility Model Content

[0004] (a) Technical problems to be solved The technical problem to be solved by this utility model is to provide a cement roller pressing device that can both enable the quick removal and repair of the pressure roller and reduce the risk of blockage when cement materials are added, in light of the current state of the technology.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a cement roller pressing device, including a processing box. Two supports are symmetrically welded to the bottom two sides of the processing box. Two movable mounting plates are symmetrically installed on the lower part of the upper two sides of the processing box. A drive motor is installed on one side wall of the movable mounting plate. A pressure roller is installed on the movable mounting plate at the power output end of the drive motor. A moving mechanism is installed between the movable mounting plate and the supports. The moving mechanism includes a motor, a threaded rod, a slide groove, and a slider. A feeding pipe is welded to the middle of the top of the processing box. A feeding hopper is slidably installed on the feeding pipe. A vibrating feeding mechanism is installed between the feeding hopper and the feeding pipe. The vibrating feeding mechanism includes a vibrating motor, a spring, and a sliding column.

[0006] Furthermore, a discharge hopper is welded to the middle of the bottom of the processing box, and a baffle plate is slidably installed at the bottom of the discharge hopper.

[0007] Furthermore, each of the moving mechanisms has two slide grooves, which are symmetrically formed on the bracket.

[0008] Furthermore, the slider is installed at the connection between the movable mounting plate and the slide groove, and the slider slides in cooperation with the slide groove.

[0009] Furthermore, the threaded rod is rotatably engaged with the slide groove, the motor is mounted on one side wall of the bracket directly opposite the threaded rod, and the motor is connected to the threaded rod via a coupling.

[0010] Furthermore, the drive motor is bolted to the movable mounting plate, the pressure roller is connected to the drive motor coupling, and the pressure roller is rotatably engaged with the movable mounting plate.

[0011] Furthermore, the vibration motor is bolted to the upper part of the outer wall of the feeding hopper, and the sliding column is installed on the outer edge of the feeding hopper on both sides of the vibration motor. The sliding column passes through the upper side of the feeding hopper and slides with the feeding hopper.

[0012] Furthermore, the spring is installed between the outer edge of the feeding hopper and the feeding pipe, and the two ends of the spring are respectively welded to the feeding hopper and the feeding pipe.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention utilizes a combined design of a moving mechanism and a movable mounting plate. A drive motor and pressure roller are mounted on the movable mounting plate. When the pressure roller is damaged after prolonged continuous rolling, the motor drives a threaded rod to move a slider along a groove. Simultaneously, the movable mounting plate is removed from the processing box, allowing for rapid exposure of the pressure roller. This enables quick repair and maintenance of the pressure roller without disassembling the entire roller press. Furthermore, by installing a vibrating feeding mechanism at the feeding pipe, the feeding hopper vibrates frequently under the action of a vibrating motor, sliding column, and spring when cement material is added. This effectively reduces the risk of cement material accumulating and clogging at the feeding pipe, facilitating efficient roller pressing of cement particles. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-3As shown, a cement roller pressing device in this embodiment includes a processing box 3. Two supports 6 are symmetrically welded to the bottom two sides of the processing box 3. Two movable mounting plates 4 are symmetrically installed on the lower part of the upper two sides of the processing box 3. A drive motor 5 is installed on one side wall of the movable mounting plate 4. A pressure roller 11 is installed on the movable mounting plate 4 at the power output end of the drive motor 5. A moving mechanism 9 is installed between the movable mounting plate 4 and the supports 6. The moving mechanism 9 includes a motor 901, a threaded rod 902, a slide groove 903, and a slider 904. A feeding pipe 2 is welded to the middle of the top of the processing box 3. A feeding hopper 1 is slidably installed on the feeding pipe 2. A vibrating feeding mechanism 10 is installed between the feeding hopper 1 and the feeding pipe 2. The vibrating feeding mechanism 10 includes a vibrating motor 10. 01. Spring 1002 and slide column 1003, when the pressure roller 11 is damaged after prolonged continuous rolling, drive the threaded rod 902 to rotate via motor 901, causing the slider 904 to move along the slide groove 903. This allows the movable mounting plate to be removed from the processing box 3 while the slider 904 moves along the slide groove 903, enabling the pressure roller 11 to be quickly exposed. This allows for rapid repair and maintenance of the pressure roller 11 without disassembling the entire roller press. At the same time, by installing a vibrating feeding mechanism 10 at the feeding pipe 2, when cement material is added, the feeding hopper 1 vibrates up and down at high frequency under the action of the vibrating motor 1001, slide column 1003 and spring 1002, thereby effectively reducing the risk of cement material accumulating and clogging at the feeding pipe 2.

[0018] like Figures 1-3 As shown in this embodiment, a discharge hopper 7 is also welded to the middle of the bottom of the processing box 3. A baffle plate 8 is slidably installed at the bottom of the discharge hopper 7. The discharge hopper 7 is mainly used to collect cement material after roller pressing. Opening the baffle plate 8 can fully discharge the cement material.

[0019] like Figures 1-3 As shown in this embodiment, each moving mechanism 9 has two sliding grooves 903. The two sliding grooves 903 are symmetrically opened on the bracket 6. The sliding grooves 903 are mainly used to provide an installation base for the threaded rod 902 and guide the sliding of the slider 904. The slider 904 is installed at the connection between the movable mounting plate 4 and the sliding groove 903. The slider 904 slides with the sliding groove 903. The threaded rod 902 rotates with the sliding groove 903. The motor 901 is installed on one side wall of the bracket 6, directly opposite the threaded rod 902. The motor 901 is connected to the threaded rod 902 by a coupling. The motor 901 is mainly used to provide power for the rotation of the threaded rod 902 so that the slider 904 can move conveniently along the sliding groove 903 under the action of thread transmission after the threaded rod 902 rotates, thereby realizing the sliding adjustment of the movable mounting plate 4 relative to the processing box 3.

[0020] like Figures 1-3As shown, in this embodiment, the drive motor 5 is bolted to the movable mounting plate 4, and the pressure roller 11 is connected to the drive motor 5 via a coupling. The pressure roller 11 and the movable mounting plate 4 are rotatably coupled. After the drive motor 5 drives the pressure roller 11 to rotate, the cement material will be rolled under the action of the pressure roller 11.

[0021] like Figures 1-3 As shown, in this embodiment, the vibration motor 1001 is bolted to the upper part of the outer wall of the feeding hopper 1. The sliding column 1003 is installed on the outer edge of the feeding hopper 1 on both sides of the vibration motor 1001. The sliding column 1003 passes through the upper side of the feeding hopper 1 and slides with the feeding hopper 1. The spring 1002 is installed between the outer edge of the feeding hopper 1 and the feeding pipe 2. The two ends of the spring 1002 are welded to the feeding hopper 1 and the feeding pipe 2 respectively. After the vibration motor 1001 is started, the feeding hopper 1 will vibrate up and down at high frequency along the sliding column 1003 under the action of the spring 1002, so as to avoid the accumulation and blockage of cement materials while the feeding hopper 1 vibrates up and down at high frequency.

[0022] The specific implementation process of this embodiment is as follows: When processing cement materials, the cement materials are first added to the feeding hopper 1, and the device is connected to an external power supply and control components. Then, the vibration motor 1001 and the drive motor 5 are started. After the vibration motor 1001 is started, the feeding hopper 1 will vibrate up and down at a high frequency under the action of the spring 1002 and the sliding column 1003, thereby effectively reducing the risk of cement materials accumulating and blocking at the feeding pipe 2. After the drive motor 5 is started, it will drive the pressure roller 11 to rotate so that the cement materials can be rolled during the rotation of the pressure roller 11. When the pressure roller 11 is damaged after long-term continuous rolling, the motor 901 drives the threaded rod 902 to rotate so that the slider 904 moves along the slide groove 903. So that while the slider 904 moves along the slide groove 903, the movable mounting plate 4 can be removed from the processing box 3, realizing the rapid exposure of the pressure roller 11. Thus, the pressure roller 11 can be quickly repaired and maintained without disassembling the entire roller press.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
