A grinding roller device with a flexible connection structure

Abstract

The invention discloses a grinder roll device with flexible connecting structures. The grinder roll device with the flexible connecting structures comprises a grinder roll head and separator body devices, and further comprises the flexible connecting structures by which the grinder roll head is connected with the separator body devices; each flexible connecting structure comprises a shaft and a mounting and connecting seat, each separator body device sleeves the corresponding mounting and connecting seat, and the mounting and connecting seat is connected with the separator body device by fasteners; holes which are coaxially matched with the shafts are separately formed in the mounting and connecting seats and the grinder roll head; and two ends of each shaft separately penetrate in and are assembled in the holes formed in the corresponding mounting and connecting seat and the grinder roll head, so that the grinder roll head and each separator body device are movably connected integrally. The invention provides the grinder roll device with the flexible connecting structures, the grinder roll device with the flexible connecting structures is simple in structure and easy to implement, compression resistance, fatigue resistance and shear resistance of positions where the grinder roll head is connected with the separator body devices are improved through the flexible connecting structures, the problem of great possibility in breakage is solved thoroughly, the service life is greatly prolonged, safety, stability and connecting strength are good, and production requirements are met easily.

Description

technical field [0001] The invention relates to the coal mill manufacturing industry, in particular to a grinding roller device with a flexible connection structure. Background technique [0002] A coal mill is a machine that breaks coal blocks and grinds them into powder; the process of coal being ground into powder in a coal mill is mainly through crushing, crushing and grinding, among which grinding is through fixing The grinding roller head on the separator body device dynamically applies pressure to the coal block between the grinding bowl liners to complete the grinding; during the grinding process, the connection between the grinding roller head and the separator body device bears huge pressure and shearing force ; At present, the grinding roller head and the separator body of most coal mills are rigidly connected by bolts, and its strength and shear resistance are difficult to reach the expected service life; on the one hand, once the connecting bolts break during op...

[0002] The coal mill is a machine that breaks coal and grinds it into powder; the process of coal being ground into powder in the coal mill is mainly through crushing, crushing and grinding, and the grinding is through fixing The grinding roller head on the separator body device dynamically applies pressure to the coal block between the grinding bowl liners to complete the grinding; during the grinding process, the connection between the grinding roller head and the separator body device bears huge pressure and shear force ; At present, the grinding roller head and the separator body device of most coal mills are rigidly connected by bolts, and its strength and shear resistance are difficult to reach the expected service life; on the one hand, once the connecting bolts break during operation, it will cause The entire grinding roller device will directly hit the grinding bowl device, which will cause serious operation safety accidents; on the other hand, in order to ensure the safe operation of the coal mill, the inspection frequency of the coal mill has to be increased, and frequent shutdowns and parts replacement are invisible In summary, the existing connection methods are difficult to meet the needs of production and service life
