Description

Technical Field

[0001] The utility model relates to the technical field of ore screening equipment, in particular to a multi-stage powder separator for ore. Background Art

[0002] Ores can be divided into metal minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in the ore is called the ore grade. After being mined, the ore needs to go through the processes of feeder, primary crushing, secondary crushing, screening, fine crushing, and dry separation. For the sake of economy, the finer the ore particle size entering the dry separation machine, the higher the proportion of mineral-bearing ore that is dry separated. Some small ore dressing plants directly dry separate the ore crushed by the fine jaw crusher, resulting in extremely serious waste of natural resources.

[0003] Ore screen is a commonly used equipment for ore screening, which is generally driven by a vibration motor. However, in the current ore screening process, the coarse material after screening is mixed with a lot of fine material. The reason is that the material flows through a short area of ​​the ore screen, and some fine material is not discharged through the screening in time, and a secondary screening process is required later. Repeated screening will lead to low material separation efficiency. If no screening is performed, it will cause material waste. Utility Model Content

[0004] Based on this, it is necessary to provide a multi-stage powder classifier for ore to address the above problems, which can avoid repeated screening and lead to low material separation efficiency.

[0008] As a preferred embodiment, a driving mechanism for driving the turntable to rotate is installed on the side of the casing. The driving mechanism includes a box body fixedly connected to the casing. A guide rod is vertically arranged in the box body. Both ends of the guide rod are connected to the inner wall of the box body through support seats. The guide rod is slidably connected to the support seats. A rack is installed on the guide rod, and a gear meshing with the rack is installed in the box body. The gear and the turntable are connected to the same central axis.

[0021] As Figures 1 - 3 shown,

[0022] As an optional embodiment of a multi-stage powder separator for ores,

[0023] A multi-stage powder separator for ores, comprising a casing 1, a support frame 7 is installed at the bottom of the casing 1, a feed hopper 2 is installed at the top of the casing 1, a first screening plate 8 is hinged on the inner wall of the casing 1 and below the feed hopper 2, a second screening plate 14 is hinged on the inner wall of the casing 1 and below the discharge end of the first screening plate 8, and a third discharge hopper 6 is installed at the bottom of the casing 1; a first corrugated square pipe 9 is installed at the bottom of the first screening plate 8, a first aggregate hopper 10 is installed at the bottom of the first corrugated square pipe 9, the first aggregate hopper 10 is installed on the side wall of the casing 1, and a first discharge hopper 3 for discharging the first aggregate hopper 10 is installed on the outer surface of the casing 1; a second corrugated square pipe 15 is installed at the bottom of the second screening plate 14, a second aggregate hopper 16 is installed at the bottom of the second corrugated square pipe 15, the second aggregate hopper 16 is installed on the side wall of the casing 1, and a second discharge hopper 4 for discharging the second aggregate hopper 16 is installed on the outer surface of the casing 1; specifically, after the above materials enter the interior of the casing 1 through the feed hopper 2, the materials flow in a "zigzag" shape and are filtered through the first screening plate 8 and the second screening plate 14. In addition to increasing the filtering length of the materials, the materials can be fully screened. After the materials pass through the first screening plate 8, they collide with the inner wall on the right side of the casing 1 once, which can reduce the flow rate of the materials and ensure the effective screening of the materials. The materials are screened twice by the first screening plate 8 and the second screening plate 14, and the materials with finer particle size are separated to the greatest extent. The finer materials can be collected through the first discharge hopper 3 and the second discharge hopper 4 respectively. The first aggregate hopper 10 and the second aggregate hopper 16 are used to support the corresponding screening plates, and the aggregate hoppers have a certain storage space inside, and they can be discharged regularly later.

[0024] As Figure 2 shown, a rectangular ring 17 is arranged inside the casing 1. The third discharge hopper 6 has a protrusion. A clamping groove matched with the protrusion is formed on the rectangular ring 17. The protrusion is located between the third discharge hopper 6 and the rectangular ring 17, and the protrusion and the third discharge hopper 6 are integrally formed. The rectangular ring 17 is fixedly connected to the inner wall of the casing 1. Subsequently, only the protrusion of the third discharge hopper 6 needs to be aligned with the clamping groove of the rectangular ring 17 and then inserted.

[0025] As Figure 2As shown in the figure, a turntable 11 is rotatably connected inside the casing 1. An eccentric first support 12 and a second support 13 are provided on the turntable 11. One ends of the first support 12 and the second support 13 are rotatably connected to the turntable 11. The other end of the first support 12 is rotatably connected to the first screening plate 8, and the other end of the second support 13 is rotatably connected to the second screening plate 14. Subsequently, the turntable 11 rotates clockwise inside the casing 1. During the rotation process, the first support 12 drives the first screening plate 8 to rotate counterclockwise. Then, the inclination of the first screening plate 8 gradually approaches the horizontal line until the first screening plate 8 lies flat slowly. During this process, the inclination of the first screening plate 8 can be adjusted to control the flow rate of the material passing through here. Similarly, when the turntable 11 rotates clockwise inside the casing 1, the second support 13 pulls the second screening plate 14 to rotate clockwise, thereby changing the inclination of the second screening plate 14 to better screen the material. Subsequently, only by controlling the rotation of the turntable 11 can the inclinations of the two screening plates be controlled simultaneously to reasonably control the flow rate of the material screening. Among them, two corrugated square pipes are respectively arranged between the screening plate and the collecting hopper to connect the two, ensuring that the material passing through the screening plate smoothly flows into the collecting hopper through the corrugated square pipe. The corrugated square pipe can expand and contract by itself, so that there is no gap between the two even after the inclination of the screening plate changes.

[0026] As Figure 3 shown in the figure, a driving mechanism 5 for driving the rotation of the turntable 11 is installed on the side of the casing 1. The driving mechanism 5 includes a box body 51. The box body 51 is fixedly connected to the casing 1. A guide rod 58 is vertically arranged in the box body 51. Both ends of the guide rod 58 are connected to the inner wall of the box body 51 through support seats. The guide rod 58 is slidably connected to the support seats. A rack 59 is installed on the guide rod 58. A gear 510 meshing with the rack 59 is installed in the box body 51. The gear 510 and the turntable 11 are connected to the same central axis. Subsequently, the driving mechanism 5 drives the turntable 11 to rotate, so as to achieve the purpose of controlling the rotation of the turntable 11. The designed driving mechanism 5 only needs to control the vertical displacement of the guide rod 58 on the support seat to drive the rack 59 to move vertically, and the meshing gear 510 rotates, so that the gear 510 drives the turntable 11 to rotate synchronously on the same shaft. Subsequently, only by controlling the lifting of the guide rod 58 can the inclinations of the two final screening plates be controlled synchronously.

[0027] As Figure 3As shown in the figure, a rotatable lead screw 55 is horizontally installed inside the box body 51. A first nut 53 and a second nut 54 are sleeved on the lead screw 55. A first connecting rod 56 is hinged to the first nut 53, and a second connecting rod 57 is hinged to the second nut 54. The other ends of the first connecting rod 56 and the second connecting rod 57 are both hinged to the bottom of the guide rod 58. Subsequently, when the lead screw 55 is rotated, the first nut 53 and the second nut 54 on the lead screw 55 move closer to or away from each other. When the two nuts move closer to each other, the guide rod 58 jointly connected by the first connecting rod 56 and the second connecting rod 57 moves upward, and finally drives the turntable 11 to rotate clockwise. On the contrary, when the two nuts move away from each other, the guide rod 58 jointly connected by the first connecting rod 56 and the second connecting rod 57 moves downward, and finally drives the turntable 11 to rotate counterclockwise.

[0028] As Figure 3 shown in the figure, bearing seats are provided at both ends of the lead screw 55. The lead screw 55 is inserted inside the bearing seats, and the bearing seats are fixedly connected to the lead screw 55. The bottoms of the two bearing seats are fixedly connected to the bottom of the box body 51. The lead screw 55 can rotate along its central axis at the bottom of the box body 51, so as to adjust the distance between the two nuts that are in threaded cooperation with it. After adjustment, stop rotating the lead screw 55, and finally realize the positioning after the rotation of the turntable 11. After the turntable 11 is positioned, the inclination of the two screening plates is controlled.

[0029] As Figure 3 shown in the figure, a first motor 52 is provided inside the box body 51. The bottom of the first motor 52 is fixedly connected to the bottom of the box body 51. The rotating shaft of the first motor 52 is connected to one end of the lead screw 55 through a coupling. Subsequently, only by controlling the first motor 52 can the inclination of the two screening plates be finally controlled.

[0030] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
