Description

Technical Field

[0001] This utility model relates to the field of roller press technology, specifically to an arc-shaped sealed feeding structure for roller presses. Background Technology

[0002] The main function of a roller press is to grind materials and improve their grindability. It is widely used in various industrial fields. The roller press uses two opposing and synchronously rotating pressure rollers to squeeze the material, causing it to be crushed and ground. This squeezing process can significantly improve the grindability of the material, making it easier for subsequent processing or use. For example, in cement production, the roller press can replace the energy-intensive and inefficient ball mill pre-grinding system, significantly increasing system output and reducing steel consumption and operating noise. Therefore, an arc-shaped sealed feeding structure for roller presses is proposed.

[0003] The existing Chinese utility model patent with publication number CN220242526U discloses a feeding device for a roller press, belonging to the field of roller press technology. This technical solution includes two main plates and two parallel first side plates whose ends are fixedly connected to the side walls of the main plates. The two main plates and the two first side plates form a feeding bin. Two opposing feeding adjustment components are arranged on the side walls of the two main plates, below the first side plates. The inclination of the second side plate is adjusted using a threaded clamping block and an adjusting rod, thereby adjusting the amount of raw material entering the machine. A driving component causes the first, second, and third push plates to move repeatedly up and down. During this up-and-down movement, the second and third push plates compact the raw material downwards, resulting in a denser and more stable downward flow, thus improving the efficiency of the roller press in crushing raw materials.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that the roller press uses a bidirectional plug-in method to close during operation, which makes it difficult to completely seal the gap in the middle. Furthermore, the roller press has a large overall structure that is not easy to disassemble and assemble, making maintenance difficult. All of these problems affect the use of the device.
