Description

TECHNICAL FIELD

[0001] The utility model relates to dressing equipment technical field, concretely relates to a novel electric separator brush unloading device. BACKGROUND

[0002] The drum type electric separator is one of main equipment for separating zircon sand. Figure 6 As shown in the figure, the drum 11 is the ground electrode and rotates clockwise, the material enters the corona electric field between the drum 11 and the corona electrode 12, the particles with good conductivity can quickly transfer the charge of the metal particles with good conductivity through the drum 11 when contacting the surface of the drum 11, and under the action of centrifugal force and gravity caused by the rotating cylinder, the particles are separated from the drum 11 and fall into the conductor product receiving groove. The non-metal or non-conductor particles with weak conductivity are difficult to transfer the charge when contacting the drum 11, so that they are adsorbed on the surface of the drum 11 under the action of the force of attracting each other by opposite charges. The side of the drum 11 is provided with a brush 13, which is used to brush the zircon sand and dust adsorbed on the surface of the drum 11, that is, the zircon sand and dust fall into the non-conductor product receiving groove. The intermediate product receiving groove is arranged between the non-conductor product receiving groove and the conductor product receiving groove.

[0003] At present, the minerals entering the electric separator may not be uniform in size, which is quite common in the mineral processing process. The non-uniform size of the mineral particles can lead to low efficiency of the brush unloading, and small particles can easily pass through the gap of the brush, while large particles can be stuck. In order to better adapt to minerals of different sizes, different densities of bristles need to be frequently replaced. Since the existing brush for unloading of the electric separator usually adopts the structure of ordinary brush with single-sided bristles, the appropriate bristles can only be replaced by disassembling and assembling the brush, which is time-consuming and affects the production efficiency.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0026] In the description of the utility model, it needs to explain, the term "center", "upper", "lower", "left" "right", "vertical", "horizontal", "internal", "external" and so on indicate the orientation or position relation based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element indicated must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the utility model, it needs to explain, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] Please refer to Figures 1-4 In an embodiment of the utility model discloses a novel electric separator brush unloading device, the novel electric separator brush unloading device includes shaft 2, worm wheel 3, worm 4 and drive device 5, wherein the cross section of shaft 2 is polygonal, specifically can be square, four longitudinal sides of shaft 2 are corresponded to four edges of the cross section of shaft 2 respectively, different density brush 6 is arranged on four longitudinal sides respectively, for brushing zircon sand and dust adsorbed on the surface of electric separator cylinder 11, worm wheel 3 is coaxially connected at one end of shaft 2, the connection mode of worm wheel 3 and shaft 2 can be key connection specifically, worm 4 and worm wheel 3 are drivingly connected to form worm wheel 3 worm 4 transmission mechanism, drive device 5 is connected at one end of worm 4, for driving worm 4 to rotate.

[0029] In use, the embodiment drives worm 4 to rotate through drive device 5, worm 4 rotates to drive shaft 2 to rotate through worm wheel 3, so that the brush 6 suitable for the size of mineral particles is close to the side of cylinder 11, to brush the mineral adsorbed on the side of cylinder 11 smoothly, so that the different density brush 6 is replaced by rotating adjustment, which is faster than disassembly and assembly, and more convenient to operate, and can well adapt to different size of mineral particles.

[0030] Since the worm gear 3 and the worm 4 transmission has high precision, the included angle between the brush 6 and the drum 11 can be accurately adjusted, so that the brush 6 and the zircon sand flow direction form an appropriate angle, usually between 45 degrees and 60 degrees. In this way, the mineral can be more easily removed by the brush 6, while avoiding excessive wear of the brush 13. In addition, since the worm gear 3 and the worm 4 transmission has self-locking, that is, after the rotation shaft 2 stops rotating, the worm gear 3 cannot rotate the worm 4 through the reverse torque, thereby locking the rotation shaft 2, the self-locking can prevent the rotation shaft 2 from generating a back error under the action of the reverse force of the drum 11, thereby improving the positioning accuracy.

[0031] Specifically, the rotation shaft 2 can be made of insulating plastic, and the brush 6 is fixedly connected to the longitudinal side of the rotation shaft 2 by injection molding. This method is simple and low in cost. Of course, the brush 6 can also be implanted on the longitudinal side of the rotation shaft 2 by a special implanting machine. This method can more accurately control the arrangement and density of the brush 6, but the cost is relatively high.

[0032] Specifically, the four brushes 6 gradually increase in density in the counterclockwise direction. By arranging the four brushes 6 in the form of gradually increasing density, the user can more easily find the appropriate setting, and the user can flexibly adjust according to needs.

[0033] Specifically, the driving device 5 is a stepping motor. The stepping motor is a kind of execution element that converts electrical pulse signals into angular displacement. It generates a rotating magnetic field by sequentially energizing a series of electromagnets, thereby driving the rotor to rotate. The stepping motor will rotate one step for each received pulse signal. Therefore, the use of a stepping motor can more accurately control the angle of rotation of the rotation shaft 2, thereby more accurately adjusting the included angle between the brush 6 and the drum 11.

[0034] On this basis, the novel brush discharging device of the electric separator of the embodiment further comprises a housing (not shown in the figure); the worm gear 3 and the worm 4 are arranged in the housing, and the housing protects the worm gear 3 and the worm 4, prevents minerals from entering the transmission mechanism, reduces wear and failure, and also has certain sound insulation and shock absorption effects.

[0035] Further, the worm 4 is rotatably connected with a first bearing with a seat 81 at both ends, and the two first bearings with a seat 81 are fixedly installed on the inner bottom wall of the housing; the rotation shaft 2 is rotatably connected with a second bearing with a seat 82 at both ends, and one of the second bearings with a seat 82 is fixedly installed on the side wall of the housing, and the other second bearing with a seat 82 is fixedly installed on the electric separator; the first bearing with a seat 81 and the second bearing with a seat 82 cooperate with the housing to provide additional structural support for the worm gear 3 and the worm 4, enhance the rigidity of the entire transmission system, and improve the running stability.

[0036] Please refer toFigure 5 In another embodiment, unlike the above embodiment, each longitudinal side of the rotating shaft 2 is fitted with an L-shaped plate 7. The two ends of the L-shaped plate 7 are detachably connected to the edge of the two end faces of the rotating shaft 2 by two spaced screws 71. The middle of the L-shaped plate 7 is fixedly connected to the bristles 6, and the fixing method can be the same as in the above embodiment. Considering that high-hardness mineral particles may cause the bristles 6 to wear out faster, affecting unloading efficiency, a detachable design allows for individual replacement of the bristles 6 when they wear out, saving time.

[0037] The method of use or working principle of this utility model is as follows:

[0038] When the discharge effect of brush 6 in the electrostatic separator is poor (small particles can easily pass through the gaps in brush 13, while large particles may get stuck), such as Figure 3 As shown, the worm gear 4 is driven to rotate by the drive device 5. The rotation of the worm gear 4 drives the rotating shaft 2 to rotate clockwise through the worm wheel 3, so that the bristles 6 with a lower density move closer to the side of the drum 11. Then, the rotating shaft 2 is rotated further to adjust the angle between the bristles 6 and the drum 11, so that the bristles 6 and the flow direction of the zircon sand are at an appropriate angle. After adjustment, the drive device 5 is turned off, and the rotating shaft 2 is locked by the self-locking property of the worm wheel 3 and worm gear 4. The unloading effect is then observed. If the effect is still poor, the above steps are repeated until the unloading effect is improved.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
