Description

Technical Field

[0001] This utility model relates to the field of raw material grinding technology, specifically a raw material grinding device for a roller press. Background Technology

[0002] Roller presses play a crucial role in cement raw material grinding plants and are one of the core pieces of equipment in modern, efficient, and energy-saving grinding systems. They use two opposing rollers to perform preliminary crushing of the raw materials, thus reducing the workload on subsequent ball mills.

[0003] Currently, when cement raw materials are initially ground in a roller press, the raw materials are fed between two pressure rollers through a feeding structure. The amount of raw materials can be controlled by a sliding adjustment plate structure on both sides. However, in actual use, the sliding adjustment requires oblique sliding to ensure the distance between the plate and the pressure roller. During the oblique sliding adjustment, the distance between the top of the plate and the hopper changes, making it easier for raw materials to enter the gap. Furthermore, during long-term use, the surface of the pressure roller is prone to raw material adhesion, which is not conducive to subsequent continuous processing. Therefore, it is necessary to improve the raw material grinding device of the roller press to solve the above problems. Utility Model Content

[0034] Furthermore, two sliding hoppers 411 are provided, and the front and back of the grinding chamber 2 are provided with sliding grooves. The sliding hoppers 411 are slidably installed inside the sliding grooves. The two sliding hoppers 411 are symmetrically threaded on the outside of the two ends of the bidirectional screw 416 with opposite thread directions around the center line of the front of the grinding chamber 2. The bidirectional screw 416 is rotatably installed with the bearing seat 417, which facilitates the synchronous reverse sliding of the two sliding hoppers 411.

[0035] Furthermore, through slots are provided on the left and right sides of the grinding chamber 2 at the corresponding positions of the baffle 412, and the baffle 412 is slidably installed inside the through slots to facilitate the baffle 412 blocking the top gap.

[0036] Furthermore, a groove is provided at the bottom of the sliding hopper 411, and the sliding plate 413 is slidably installed inside the groove, so that the sliding plate 413 can slide at the bottom of the sliding hopper 411.

[0037] Furthermore, the grinding assembly 42 includes a mounting plate 421, which is fixedly mounted on the top of the support frame 1 near the front side.

[0038] Furthermore, two of the second motor 422, transmission rod 423, and grinding roller 424 are provided, and they are symmetrically arranged with respect to the center line of the front of the grinding chamber 2, so that the two grinding rollers 424 can rotate in opposite directions.

[0039] Example 2:

[0040] To clean the surface of the grinding roller 424, please refer to... Figure 8Furthermore, in conjunction with Embodiment 1, the cleaning mechanism 5 includes a mounting frame 51, which is fixedly mounted on the back of the grinding chamber 2. A third motor 52 is fixedly mounted inside the mounting frame 51. A cleaning roller brush 53 is rotatably mounted inside the grinding chamber 2 extending to the back, and the cleaning roller brush 53 contacts the surface of the grinding roller 424. A first synchronous wheel 54 is fixedly mounted through the back of the cleaning roller brush 53 through the grinding chamber 2. A rotating rod 55 is rotatably mounted on the back of the grinding chamber 2. A second synchronous wheel 56 and a gear 58 are fixedly mounted on the outside of the rotating rod 55. A synchronous belt 57 is installed between the first synchronous wheel 54 and the second synchronous wheel 56 to facilitate cleaning the surface of the grinding roller 424.

[0042] In actual operation, when this device is used, cement raw materials are added from the top of the grinding bin 2, and two second motors 422 are started. The two second motors 422 drive the transmission rod 423 to rotate synchronously in opposite directions, so that the transmission rod 423 drives the two grinding rollers 424 to rotate synchronously inward in opposite directions, so that the two grinding rollers 424 press and grind the raw materials. At the same time, the first motor 415 drives the bidirectional screw 416 to rotate, so that the bidirectional screw 416 drives the two sliding bins 411 to slide synchronously, so that the distance between the two sliding bins 411 can be adjusted. Meanwhile, the hydraulic rod 414 drives the sliding plate 413 to slide at the bottom of the sliding bin 411, so that the feed rate can be controlled by adjusting the distance.

[0043] Simultaneously, the third motor 52 drives the rotating rod 55 to rotate, causing the gear 58 on the rotating rod 55 to drive another rotating rod 55 to rotate synchronously in the opposite direction. This causes the rotating rod 55 to drive the second synchronous wheel 56 to rotate, which in turn drives the first synchronous wheel 54 to rotate via the synchronous belt 57. The synchronous wheel then drives the cleaning roller brush 53 to rotate inside the grinding chamber 2, allowing the cleaning roller brush 53 to clean the surface of the grinding roller 424.
