Technical Field

[0001] The utility model relates to the technical field of ore dressing, in particular to a disc rotary ore dressing machine. Background Art

[0002] Talc is a common silicate mineral, the softest known mineral, with a lubricating feel, hydrophobicity, inactive chemical properties, high electrical insulation, thermal insulation, high melting point and strong adsorption properties for oils. It is widely used in industry. Most of the talc used in industry is talc powder and talc pen. Its production process must go through multiple processes such as mining, ore dressing, and crushing. The associated minerals of talc in my country are dominated by carbonate minerals, such as calcite, dolomite, and magnesite, followed by chlorite, quartz, tremolite, and some are serpentine and mica. The existing methods of talc beneficiation are mainly divided into hand selection, optical selection, flotation, and drum talc beneficiation. Optical selection is to use light source irradiation, under which talc and gangue have different luminescence; flotation is to use the characteristics of talc being oil-loving and gangue being hydrophilic; drum talc beneficiation machine uses the different friction coefficients of talc and miscellaneous stones for separation.

[0003] The above-mentioned various beneficiation methods are not only complex in process, large in equipment investment, high in maintenance cost, large in floor space, high in energy consumption, and high in noise, but also have a narrow scope of application and are difficult to promote and apply. Manual selection has high labor intensity and low production efficiency. The drum type talc beneficiation machine occupies a large area, has a large weight, and is very noisy. Therefore, the technology for beneficiation of talc needs to be improved. Utility Model Content

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] A disc rotary concentrator comprises a disc 1, a driving device, a feeding device and a screening device. The disc 1 is arranged above the driving device, and the disc 1 is connected to the output end of the driving device and is driven to rotate by the driving device. The feeding device is arranged on one side above the disc 1 and conveys the raw material downward onto the disc 1, and the screening device is arranged above the disc 1 and blocks the raw material rotating with the disc 1, so that the talc and the sundry stones in the raw material are discharged from different outlets respectively to separate the talc and the sundry stones in the raw material.

[0035] like Figure 1 As shown, the driving device includes a frame 2 and a motor 3. The frame 2 is located below the disc 1, and the output end of the motor 3 is fixed on the frame 2 with the output end facing upward, and the output end of the motor 3 is connected to and drives the disc 1 to rotate. A support foot 4 for adjusting the height of the device is provided at the bottom of the frame 2.

[0036] like Figure 1 As shown, the feeding device includes a hopper 5 and a feeder 6. The hopper 5 is fixed on one side above the disc 1, and the feeder 6 is arranged below the discharge port of the hopper 5 and continues to output the raw materials output by the hopper 5 to the disc 1.

[0037] like Figure 2-4As shown, the screening device includes a baffle plate 7, an ore scraper 8 and a rock scraper 9. The baffle plate 7 is a hollow columnar structure, which is fixed above the outer periphery of the disc 1 by a baffle frame. Preferably: the baffle frame is a plurality of support rods 10, the upper ends of the support rods 10 are evenly fixedly connected to the outer wall of the baffle plate 7, and the lower ends thereof extend vertically downward to the ground. The baffle plate 7 is provided with two notches at intervals, and the two notches respectively form an ore outlet 11 and a rock outlet 12, and the ore outlet 11 is located behind the rock outlet 12 in the direction of rotation of the raw material. The ore scraper 8 is fixed on the front side wall of the ore outlet 11 along the direction of rotation of the raw material, and its two ends extend to the inner side of the baffle plate 7 and the outer side of the baffle plate 7 by a preset distance, and one end of the ore scraper 8 located on the inner side of the baffle plate 7 is located behind the other end in the direction of rotation of the raw material. The rock scraper 9 is fixed on the front side wall of the rock outlet 12 along the direction of raw material rotation, and its two ends extend to the preset distances inside and outside the baffle plate 7, respectively, and one end of the rock scraper 9 on the inside of the baffle plate 7 is behind the other end in the direction of raw material rotation, and the end of the rock scraper 9 on the inside of the baffle plate 7 is closer to the center of the disc 1 than the end of the ore scraper 8 on the inside of the baffle plate 7. The screening device also includes a first baffle 13, a second baffle 14 and a connecting plate 15. The first baffle 13 and the second baffle 14 are arc-shaped structures, and the first baffle 13 and the second baffle 14 are spaced apart in the baffle plate 7 at the position corresponding to the raw material output of the feeder 6. One end of the first baffle 13 is fixed at the corresponding position of the baffle plate 7, and the two ends of the connecting plate 15 are fixedly connected to the top of the middle position of the first baffle 13 and the second baffle 14, respectively.

[0038] The ore dressing machine further comprises a spray head 16, which is located above the position where the feeder 6 outputs the raw materials and sprays water to wash the raw materials and the disc 1. The spray head 16 is fixedly connected to the outer side wall of the baffle plate 7 through a connecting rod 17.

[0039] The working process of the concentrator is as follows:

[0040] Raw materials within the same particle size range (talc and miscellaneous stones have different masses) are uniformly dropped on one side of the turntable 1 through the hopper 5 and the feeder 6 (the feeder 6 can be a belt conveyor) and are located between the first baffle 13 and the second baffle 14. The motor 3 drives the materials to rotate through the turntable 1. Under the restriction of the first baffle 13 and the second baffle 14, on the one hand, the raw materials are prevented from falling on the center of the turntable 1 and not rotating with the turntable 1. On the other hand, the talc and miscellaneous stones in the raw materials obtain the same initial velocity when leaving between the first baffle 13 and the second baffle 14, so that the talc and miscellaneous stones can be sorted later.

[0041] After the raw material leaves between the first baffle 13 and the second baffle 14, due to the large difference in friction coefficient between talc and miscellaneous stones, under the action of deadweight, centrifugal force, and friction force, and the particle sizes of talc and miscellaneous stones are in the same range, and both have initial velocities in the same range, the centrifugal force generated by the rotation of the disc 1 on the talc on the disc 1 is greater than the maximum static friction generated between the talc and the disc 1, causing the talc to move toward the outer circle of the disc 1. Since the friction force generated by the miscellaneous stones on the disc 1 is greater than the friction force between the talc and the disc 1, the speed of the miscellaneous stones sliding on the disc 1 is slower than that of the talc or there is no sliding, and it moves toward the inner circle of the disc 1. Finally, the talc on the outer circle of the disc 1 is blocked by the talc ore scraper 8 and discharged from the ore outlet 11, and the miscellaneous stones on the inner circle of the disc 1 are blocked by the miscellaneous stone ore scraper 9 and discharged from the miscellaneous stone outlet 12, thereby achieving the separation of talc and miscellaneous stones. The talc ore scraper 8 and the sundry rock ore scraper 9 are arranged obliquely, so that the talc and ore can be discharged from the ore outlet 11 and the sundry rock outlet 12 more easily.

[0042] During the above-mentioned mineral processing, the spray head 16 washes the surface of the raw material and also washes the working surface of the disc 1 to ensure that the working surface is clean.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
