Description

Technical Field

[0001] This utility model relates to the field of power mineral processing equipment technology, specifically to a cleaning roller for an electric separator. Background Technology

[0002] Electrostatic separators are dry mineral processing equipment that separates minerals based on differences in their electrical conductivity using a high-voltage electric field. The core principle is that minerals with different electrical conductivity exhibit different trajectories due to electrostatic induction or the capture of charged ions in an electric field, achieving separation through the combined effect of gravity. For example, highly conductive minerals like magnetite and ilmenite can be effectively separated from less conductive minerals like quartz and feldspar using electrostatic separation. However, the brushes used in these separators are consumables. Wear and tear from contact with the rotating drum further degrades the cleaning effect, negatively impacting the normal operation and separation efficiency of the separator. Currently, in existing electrostatic separators, the positions of the brushes and their power sources are mostly fixed, making it impossible to flexibly adjust the shaft spacing. When brushes wear down, replacement is necessary to ensure effective contact with the drum, significantly increasing production costs. Utility Model Content

[0003] This invention addresses the problems mentioned above by designing a cleaning roller for an electrostatic separator, enabling adjustment of the shaft spacing between the brush roller body and the drum, ensuring effective brushing of the brush roller body, and extending its service life.

[0004] To achieve the above objectives, this utility model provides a cleaning roller for an electrostatic separator, comprising a power source and a brush roller body installed inside the casing. The power source drives and connects to the brush roller body. The brush roller body rotates in the same direction as the drum and is in side contact with each other. A guide rail is fixedly provided on the inner wall of the casing. The power source and the brush roller body are slidably connected to the casing through an adjustment mechanism.

[0005] Furthermore, the adjustment mechanism includes a slider that is slidably connected to the guide rail, and a connecting plate one and a connecting plate two that are respectively fixedly connected to the slider. The outer shell of the power source is fixedly connected to the connecting plate one, and the connecting plate two is fixedly connected to a bearing seat. One end of the brush roller body is connected to the output shaft of the power source, and the other end is connected to the bearing seat through a rotating shaft.

[0006] Furthermore, the guide rail is fixedly connected to a limiting plate, which blocks the slider.

[0007] Furthermore, the adjustment mechanism also includes an intermediate support plate and an adjustment rod. The intermediate support plate has a threaded hole and is fixedly connected to the connecting plate one and the connecting plate two at both ends. One end of the adjustment rod is tapped with an external thread that matches the threaded hole, and the adjustment rod is threadedly engaged with the intermediate support plate.

[0008] Furthermore, the chassis has a through hole, and the other end of the adjusting rod passes through and is rotatably connected to the chassis.

[0009] Furthermore, the threaded end of the adjusting rod is fixedly connected to a second limiting plate, which in turn blocks the intermediate support plate.

[0010] Furthermore, the adjusting rod is also equipped with a limiting plate three and a limiting plate four, which cover the through hole and abut against the inner and outer walls of the chassis respectively.

[0011] Furthermore, the brush roller body includes a roller and brush bristles, the roller has a hollow structure, and the brush bristles are fixedly connected to the roller.

[0012] Furthermore, the roller is symmetrically provided with annular mounting grooves, the axis of which coincides with the axis of the roller.

[0013] Furthermore, both the rotating shaft and the output shaft of the power source are fixedly connected to flange support seats, and the flange end of the flange support seat is engaged with the mounting groove.

[0014] In summary, this utility model has the following advantages and beneficial technical effects:

[0015] 1. This utility model adds an adjustment mechanism to adjust the axial distance between the brush roller body and the drum, ensuring effective brushing by the brush roller body, extending its service life, and saving production costs. Manually rotating the adjustment rod causes the intermediate support plate to drive the brush roller body towards the drum. The operation principle is simple, enhancing the flexibility and operability of the equipment.

[0016] 2. The design of the annular mounting groove and flange support in this utility model effectively limits the axial displacement of the brush roller body. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail as follows:

[0031] like Figures 1-2 As shown, this embodiment discloses a cleaning roller for an electrostatic separator, including a power source 3 and a brush roller body 2 installed inside the electrostatic separator housing 1. In this embodiment, the power source 3 is a motor that drives the brush roller body 2. The brush roller body 2 rotates in the same direction as the rotating drum 4 in the electrostatic separator and is in side contact with each other. A set of opposite side walls inside the housing 1 are fixedly connected to guide rails 11. The power source 3 and the brush roller body 2 are slidably connected to the guide rails 11 through an adjustment mechanism 5. A limit plate 12 is welded to the free end of the guide rail 11. The limit plate 12 is used to block and limit the slider.

[0032] like Figures 1-5As shown, the adjustment mechanism 5 includes a slider, a first connecting plate 51, and a second connecting plate 52. In this embodiment, there are two sets of sliders, which are slidably connected to the guide rail 11. The first connecting plate 51 and the second connecting plate 52 are fixedly connected to the sliders. The outer shell of the power source 3 is installed on the first connecting plate 51 by fastening screws. The second connecting plate 52 is fitted with a bearing seat 6 by screws. One end of the brush roller body 2 is engaged with the output shaft of the power source 3, and the other end is rotatably connected to the bearing seat 6 through the rotating shaft 7. The adjustment mechanism 5 also includes an intermediate support plate 53 and an adjustment rod 54. The intermediate support plate 53 has a threaded hole through it, and the two ends are bent into the first connecting plate 51 and the second connecting plate 52 respectively. One end of the adjustment rod 54 is tapped with an external thread that matches the threaded hole. The adjustment rod 54 is threadedly engaged with the intermediate support plate 53. The housing 1 has a through hole, and the other bare end of the adjustment rod 54 passes through the through hole and is rotatably connected to the housing 1 through a bearing.

[0033] like Figure 4 As shown, the threaded end of the adjusting rod 54 is welded with a second limiting plate 55, which is used to block the intermediate support plate 53. The adjusting rod 54 is also equipped with a third limiting plate 56 and a fourth limiting plate 57. The third limiting plate 56 and the fourth limiting plate 57 cover both sides of the through hole and are rotatably pressed against the inner and outer walls of the housing 1, which can limit the horizontal position of the adjusting rod 54 and control the particle diffusion during the screening process of the electric separator.

[0034] like Figures 6-7 As shown, the brush roller body 2 includes a roller and brush bristles. The roller has a hollow structure, and the brush bristles are fixedly connected to the roller. Circular mounting grooves 21 are symmetrically opened at both ends of the roller, and the axis of the mounting grooves 21 coincides with the axis of the roller. The output shaft of the rotating shaft 7 and the power source 3 are mounted with T-shaped flange support seats 8 by screws. The flange end of the flange support seat 8 is engaged in the mounting groove 21 and fixedly connected to the roller by screws.

[0035] The working principle of a cleaning roller for an electrostatic separator according to this utility model is as follows:

[0036] When the electrostatic separator is in use, the power source 3 is started, and the output axis of the brush roller body 2 is used to transmit power to drive the brush roller body 2 to rotate, thereby brushing off the non-conductive particles on the rotating drum 4 that are rotating in the same direction. When the brush bristles are worn and the shaft diameter of the brush roller body 2 decreases, in order to ensure that the brush roller body 2 and the rotating drum 4 make effective contact, the adjusting rod 54 is manually rotated. According to the principle of screw and nut transmission, the intermediate support plate 53 drives the connecting plate 1 51 and the connecting plate 2 52 to move towards the rotating drum 4 until the bristles of the brush roller body 2 contact the side of the rotating drum 4.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
