Description

Technical Field

[0001] The utility model relates to the technical field of coal mills, in particular to a segmented coal mill. Background Art

[0002] Coal mill is a machine that breaks coal blocks and grinds them into coal powder. It is an important auxiliary equipment for coal powder furnace. There are vertical mills, high-pressure suspension roller mills, medium-speed micro-powder mills, super-pressure trapezoidal mills, Raymond mills and other models.

[0003] Authorization announcement number CN218689957U discloses a segmented coal mill, including a mounting seat, a left fixed seat and a right fixed seat symmetrically arranged at the top of the mounting seat, and a segmented moving ring sleeved on the end of the right fixed seat and a segmented static ring sleeved on the end of the left fixed seat. The ends of the left fixed seat and the right fixed seat are provided with connecting mechanisms, and the connecting mechanism includes connecting components symmetrically arranged at the ends between the right fixed seat and the segmented moving ring and between the left fixed seat and the segmented static ring, and guide components, limit components, adjustment components, and fixing components respectively arranged on both sides, the inner side, and the top of the ends of the connecting components; the surface of the segmented moving ring is provided with a moving ring operating mechanism; the surface of the segmented static ring is provided with a static ring operating mechanism. The utility model can accurately dock the segmented static ring with the fixed seat, and can also accurately align the positioning hole with the screw hole at the bottom end of the connecting block, so that the connecting block can be firmly positioned by tightening the positioning rod, which makes up for the many inconveniences in the installation of the dynamic and static rings of the existing segmented coal mill.

[0004] The segmented coal mill uses a compressed telescopic spring to accurately connect the dynamic and static rings with the fixed seat. However, after long-term use, the elasticity of the telescopic spring is easily reduced, resulting in unstable connection between the dynamic and static rings and the fixed seat. For this reason, we propose a segmented coal mill. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.
