Description

Technical Field

[0001] This utility model relates to the field of iron concentrate processing technology, specifically to a mineral processing and screening device for iron concentrate processing. Background Technology

[0002] Iron concentrate originates from iron ore, which is an iron-containing mineral formed during geological processes. These ores are mainly distributed in mines around the world, with abundant iron ore resources in parts of Australia, Brazil, and China. Iron ore is extracted from mines through open-pit or underground mining. Freshly mined iron ore varies in size, ranging from large blocks to fine particles. To facilitate subsequent processing, the mined iron ore needs to be crushed. Crushers are typically used to break large blocks of ore into smaller particles. This process may involve multiple stages of crushing, such as coarse crushing with a jaw crusher, followed by medium and fine crushing with equipment like cone crushers, to bring the iron ore particle size to a suitable range, typically from a few millimeters to tens of millimeters. This is the first step in producing iron concentrate.

[0003] In the existing technology, in the first process of a mining beneficiation plant, the freshly mined and crushed iron ore raw material is transported to this beneficiation screening device. At this time, the screening device can perform preliminary separation of ore particles of different sizes. During use, the existing screening structure usually has low screening efficiency and incomplete screening, which can easily increase the number of screening times. Moreover, after screening, some iron concentrate powder usually remains on the surface of the screen. If not treated, it may cause clogging problems and increase screen wear.

[0004] Therefore, a mineral processing and screening device for iron concentrate processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a mineral processing and screening device for iron concentrate processing, so as to solve the problems mentioned in the background art.

[0011] Preferably, a filter screen is fixedly installed between the inner walls of the fixed frame, and grooved side rods are fixedly installed on both sides of the fixed frame. Rollers are movably connected between the inner walls of the grooved side rods. The surface of the rollers contacts the top of the support plate. Through the cooperation between the motor and cam two, the bidirectional grooved plate, roller one, cam one, connecting plate, L-shaped connecting plate, and extrusion plate one can be moved. Finally, the connecting rod, sleeve block, fixed frame, and filter screen are driven to screen the material. Through the cooperation between extrusion plate one, extrusion plate two, and spring, cam one can be reset. The larger particles of ore screened out by the top layer of the screen can be returned to the previous process for further processing. The iron concentrate screened out by the middle layer of the screen is transported to the corresponding processing stage through the discharge port. The finest iron concentrate collected by the bottom layer of the screen enters a special fine powder collection container through the discharge port. The collection trough at the bottom collects ultrafine iron concentrate, thus achieving the effect of layered screening.

[0012] Preferably, the cleaning component specifically includes: a placement slot, which is formed on the top side of the fixed frame; and a motor, which is fixedly installed on the inner wall of the placement slot.

[0013] Preferably, a lead screw is fixedly installed at the output end of the motor, and the other end of the lead screw is rotatably connected to the other side of the inner wall of the placement groove.

Through the cooperation between the motor, lead screw, threaded block, bent plate, and connecting block, the cleaning brush can be driven to clean the surface of the filter screen, avoiding material accumulation. The cleaning brush can directly contact the surface of the filter screen. When iron concentrate particles accumulate or tend to clog at the filter screen holes, the brush bristles can brush these particles away from the screen holes, ultimately achieving a cleaning effect.

The three-layer fixed frame is moved by the sleeve block. The movement of the connecting plate will drive the first extrusion plate to move. Under the action of the second extrusion plate, the spring will be compressed and rebounded. Compared with the traditional single screen multiple screening method, it reduces the transfer and waiting time of materials between different screening equipment, thereby achieving the effect of layered screening.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1:

[0025] A preferred embodiment of the mineral processing and screening device for iron concentrate processing provided by this utility model is, for example... Figure 1-4 As shown: A mineral processing and screening device for iron concentrate processing includes a support plate 1, with legs 2 fixedly installed at equal intervals on both sides of the bottom of the support plate 1, a drive seat 3 fixedly installed on one side of the top of the support plate 1, a layered screening component 4 disposed inside the drive seat 3, a cleaning component 5 disposed on the surface of the layered screening component 4, and a collection trough 6 disposed on the top of the support plate 1.

[0026] The layered screening component 4 specifically includes: a grooved rail 411, which is fixedly installed on both sides of the inner wall of the drive seat 3; a bidirectional grooved plate 412, which is set inside the drive seat 3; a motor 4111, which is fixedly installed at the bottom inside the drive seat 3; and a second extrusion plate 418, which is fixedly installed at the bottom of the inner wall of the drive seat 3.

[0027] A roller 413 is rotatably connected between the inner walls of the bidirectional groove plate 412. The surface of the roller 413 is slidably connected to the inner wall of the groove rail 411.

The other end of the springs 419 is fixedly connected to one side of the pressing plate 418. A cam 4112 is fixedly installed at the output end of the motor 4111.

[0029] The top of the L-shaped connecting plate 416 is provided with connecting rods 4113 at equal intervals. The bottom of the connecting rods 4113 passes through the top of the L-shaped connecting plate 416 and extends to the bottom of the L-shaped connecting plate 416. The outer wall of the connecting rods 4113 is uniformly and evenly fitted with sleeve blocks 4114. A fixing frame 4115 is fixedly installed on one side of the sleeve block 4114.

[0030] A filter screen 4116 is fixedly installed between the inner walls of the fixed frame 4115. Grooved side rods 4117 are fixedly installed on both sides of the fixed frame 4115.

The three-layer fixed frame 4115 is moved by the sleeve block 4114. The movement of the connecting plate 415 will drive the first extrusion plate 417 to move. Under the action of the second extrusion plate 418, the spring 419 will be compressed and rebound, thereby achieving the effect of layered screening.

[0032] Example 2:

[0033] Based on Embodiment 1, a preferred embodiment of the mineral processing and screening device for iron concentrate processing provided by this utility model is as follows: Figure 1-4 As shown: The cleaning component 5 specifically includes: a placement slot 511, which is opened on the top side of the fixing frame 4115; and a motor 512, which is fixedly installed on the inner wall side of the placement slot 511.

[0034] A lead screw 513 is fixedly installed at the output end of the motor 512. The other end of the lead screw 513 is rotatably connected to the other side of the inner wall of the placement groove 511. A threaded block 514 is threadedly connected to the outer wall of the lead screw 513. The two sides of the threaded block 514 are slidably connected to the inner wall of the placement groove 511. A bent plate 515 is fixedly installed on the top of the threaded block 514. A connecting block 516 is fixedly installed on the bottom of the bent plate 515. The bottom of the connecting block 516 extends into the interior of the fixed frame 4115. A cleaning brush 517 is fixedly installed on one side of the connecting block 516. The surface of the cleaning brush 517 is in contact with the surface of the filter screen 4116.

[0035] In this example, the filter screen can be cleaned by setting the cleaning component 5 to prevent clogging. The motor 512 is started to drive the lead screw 513 to rotate, which in turn drives the threaded block 514, the bent plate 515 and the connecting block 516 to move, and finally drives the cleaning brush 517 to clean the surface of the filter screen, thereby achieving the cleaning effect.

[0036] Working principle: First, the operator places the material onto the top filter screen 4116, then starts the motor 4111 to drive the second cam 4112 to rotate, which in turn moves the first cam 414, the bidirectional groove plate 412, the connecting plate 415, the L-shaped connecting plate 416, and the connecting rod 4113. The bidirectional groove plate 412 slides stably within the grooved rail 411 via the first roller 413, and moves the three-layer fixed frame 4115 via the sleeve block 4114. The movement of the connecting plate 415 causes the first extrusion plate 417 to move. Under the action of the second extrusion plate 418, the spring 419 is compressed and rebounds, achieving the back-and-forth movement of the fixed frame 4115. The fixed frame 4115 is supported by the grooved side rod 4117 and the second roller 4118 on the support plate 1. The uppermost layer of the filter screen 4116 screens out larger ore particles, which are then returned to the previous process for further processing. The middle layer of the filter screen 4116 screens out medium-sized iron concentrate, which is then transported to the corresponding processing stage through the outlet of the fixed frame 4115. The bottom layer of the filter screen 4116 collects the finest iron concentrate, and the collection trough 6 collects the ultrafine iron concentrate falling from the bottom. When the filter screen 4116 needs to be cleaned, the motor 512 is started to drive the lead screw 513 to rotate, which in turn moves the threaded block 514, the bending plate 515, and the connecting block 516. Finally, the cleaning brush 517 cleans the surface of the filter screen, achieving back-and-forth cleaning of the surface of the filter screen 4116, thereby achieving the functions of layered screening and cleaning.
