Embodiment Construction

[0026] Such as Figure 1 to Figure 3 shown in figure 1 The left direction is the left direction of the present invention, that is, the figure 1 The orientation of the axis of the middle drum shaft is the left and right horizontal direction of the present invention, and the radial direction from the outer circle of the drum shaft to the inner circle of the drum is the direction from the inside to the outside. The new sealing device includes a drum 1 and a drum shaft 2. The left and right ends of the drum 1 are fixedly connected with a radial plate 3 inward along the circumferential direction. The radial plate 3 is welded on the drum 1, and the two radial plates 3 are respectively fixedly connected. There is a left first connecting seat and a right first connecting seat coaxial with the spoke plate 3, the structures of the left first connecting seat and the right first connecting seat are the same and symmetrical, and the drum shaft 2 is rotationally connected to the left by th...

Abstract

Disclosed is a novel sealing device of a belt conveyor roller shaft under anti-corrosion and dust-proof special working conditions. The novel sealing device includes a roller and the roller shaft. A left first connecting seat and a right first connecting seat are of the same structure and in bilateral symmetry. The right first connecting seat includes an inner end cover and a first bearing seat which are installed from left to right in sequence in the axial direction. The first bearing seat is provided with a first bearing installation part and a first sealing part from left to right in sequence in the axial direction. The first sealing part is provided with a first magnetorheological fluid curve sealing structure. The left and right ends of the roller shaft are provided with a left secondconnecting seat and a right second connecting seat separately. The right second connecting seat includes a second bearing seat and a bearing end cover. The second bearing seat is provided with a second sealing part and a second bearing installation part from inside to outside in sequence in the axial direction. The second sealing part is provided with a second magnetorheological fluid curve sealing structure. According to the novel sealing device, by using the magnetorheological fluid curve sealing structures, contact sealing is changed into non-contact sealing; the fact that wear of a sealing piece affects the sealing effect of the roller shaft is avoided; and the service life of the roller shaft is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to the rotary seal of the drum shaft of a belt conveyor in coal mine equipment. Background technique [0002] The belt conveyor is one of the important equipment in coal mine transportation, and the roller is an important part and part of the machine. Aiming at the problem of frequent replacement of belt conveyor rollers in coal mines, especially the tail roller parts of belt conveyors, and the high failure rate of equipment, the working conditions and main sealing structures of the tail rollers are analyzed. [0003] During the underground transportation of coal, the tail reversing drum at the lower end of the belt conveyor is soaked in water, coal, mud and other mixtures for a long time due to the limitation of underground working conditions, so it has a high impact on the sealing structure and service life of the drum. Require. At present, most of the traditional rever...
