Description

Technical Field

[0001] This utility model relates to the field of material impurity removal technology for vertical mills, and in particular to a material impurity removal mechanism for vertical mills. Background Technology

[0002] In the material removal process of vertical mills, the effectiveness of raw material removal significantly impacts the safe operation of the equipment and the quality of the finished product. To efficiently remove small particles (such as sand and mud) mixed in the material, a dedicated material removal mechanism is typically required. This mechanism usually includes core functional modules such as screening and separation, air separation, and wear-resistant protection. Especially in the process of removing high-hardness impurities, the wear resistance and separation efficiency of the mechanism directly affect operating costs and product quality, given the associated risks of equipment wear and the requirements for separation accuracy. Therefore, developing a modular, efficient, and easy-to-maintain material removal mechanism has become an important direction for technological improvement.

[0003] In existing technologies, the material removal mechanisms of vertical mills generally include an impurity separation device, a material conveying channel, and an impurity collection structure. Structurally, the mechanism contains core components for screening or adsorbing impurities (such as screens, magnetic separators, or air separators), integrated into the material path through fixed installation or bolt fastening. In practical use, the materials being screened vary in size, and the impurities they contain also vary in size. Existing screens are mostly integrated units, which cannot handle a wider range of materials or adapt to diverse workloads.

[0004] However, existing material removal mechanisms for vertical mills still have certain problems in practical applications. On the one hand, due to the varying sizes of materials being screened, traditional structures, mostly integrated, cannot replace the screens and therefore cannot effectively remove impurities, affecting the purity of the grinding process. On the other hand, the screens cannot remove small particles such as mud and sand. These problems reduce the accuracy and convenience of material removal in vertical mills, necessitating optimization in structural design. Therefore, a new material removal mechanism for vertical mills is proposed to address these issues. Utility Model Content

[0024] 1. In this utility model, pulling the lever causes the sliding block to compress the spring, and the sliding block slides in inner groove one and inner groove two. The sliding block leaves the inside of the locking block, thereby removing the fixing of the shell and the screen. The screen is pulled out, and the replacement screen is inserted into the discharge port. The sliding block has an inherent inclined surface mechanism, and the locking block is inserted into the compression spring. When the locking block is brought to the designated position, the sliding block slides into inner groove two under the spring rebound and is fixed.

[0025] 2. In this utility model, the starting motor, under the combined action of the rotating plate two, the rotating column two, and the rotating column one, converts the rotational motion of the motor into the up-and-down movement of the limiting block. The limiting block drives the track column to slide in the inner groove three. The inner groove three has a special angle, and the track column rotates, thereby driving the drum to rotate up and down in a cyclical motion, achieving the up-and-down rotational motion of the drum. This solves the problem that it is not convenient to clean the small particles in the material during the operation of the vertical mill material removal process, and improves the accuracy of the excitation and demagnetization tool.

The top of the tank 1 is provided with a quick-change component for stable and quick replacement of the screen 3. The top of the tank 1 is provided with a rolling component, which rolls up and down to screen out all fine impurities.

The bottom of the feed pipe 4 is fixedly connected to the top of the tank 1. A screen 3 is slidably connected inside the feed pipe 4 to filter impurities in the material. The replaceable mesh design adapts to the impurity removal needs of materials with different particle sizes.

Providing dust protection and extending component lifespan, the housing 5 has an inner groove 7 to restrict the movement trajectory of the sliding block 10, ensuring precise locking and unlocking actions. A pull rod 6 is slidably connected inside the housing 5 to transmit manual pulling force, driving the sliding block 10 out of the inner groove 12 for quick unlocking and screen replacement.

One end of the roller 17 is rotatably connected to a rotating column 2, transmitting the rotational force of the motor 18 to the roller 17, and linking the trajectory control... The control system includes a trajectory column 23 fixedly connected to one end of the rotating column 2, used to move along a specific trajectory of the inner groove 22, converting the up-and-down sliding motion into rotational motion. The trajectory column 23 is rotatably connected to a connecting block 20, used to integrate a trajectory transmission mechanism, converting the horizontal movement direction to a motion conversion component.

The trajectory block 21 is fixedly connected to the outer wall of the fixing block 31, used to define the movement path of the trajectory column 23, and control the rotation and lifting law of the roller 17 through the curved groove. The trajectory block 21 has an inner groove 3 inside. 22 is used to force the trajectory column 23 to move along a preset curve, realizing the up-and-down rotational cyclic motion of the roller 17. The outer wall of the trajectory column 23 is slidably connected to the inner groove 22. The top of the extension frame is fixedly connected to the extension frame 26, which is used to raise the installation height of the motor 18 and avoid material contamination. The top of the extension frame 26 is fixedly connected to the motor 18 to provide rotational power. The output end of the motor 18 is fixedly connected to the rotating plate 28 to transmit the torque of the motor 18 and amplify the rotational torque. The outer wall of the rotating plate 28 is fixedly connected to the rotating column 27, which is used to convert the circular motion into rocker motion.

The rotating plate 16 is rotatably connected to the rotating column 25, and one end of the rotating column 15 is fixedly connected to one end of the limiting block 19.

[0038] Working principle: When using the material removal mechanism of this vertical mill, pull the lever 6 to drive the sliding block 10 to compress the spring 11. The sliding block 10 slides in the inner groove 7 and the inner groove 2 12. The sliding block 10 leaves the inside of the locking block 9, thereby releasing the fixing of the shell 5 and the screen 3. Pull out the screen 3 and insert the replacement screen 3 into the discharge port. The sliding block 10 has an inherent inclined surface mechanism. The insertion of the locking block 9 causes the sliding block 10 to compress the spring 11. The sliding block 10 slides outward, thereby allowing the locking block 9 to be inserted into the inner groove 7. When the locking block 9 is brought to the designated position, the sliding block 10 slides into the inner groove 2 12 under the rebound action of the spring 11, thereby fixing the shell 5 and the screen 3.
