As shown in fig. 1 to 4, example 1 provides a production line for extracting and separating mica and weak magnetic substances from tailings, which comprises a bin 1, a high-frequency sizing screen 2, three ultrasonic cleaning chutes, four water cyclones, three magnetic separators, three shaking tables, a rod mill 19, a lifting device 21, two dewatering screens, a filtering collecting barrel 16 and a presser 20.
The storage bin 1 (also called a transfer bin) is built at a high position and is generally built on a working platform with the height of 6-9m, and tailings materials (also called tailing sand or tailings) are lifted into the storage bin 1 through a lifting device 21. The particle size of the tailings in this example is below 5 mm.
The material bin 1 is connected with the high-frequency material separating sieve 2. The material in the material bin 1 is provided with a certain amount, and is discharged into the high-frequency material separating sieve 2 after being added with water. When the high-frequency material separating sieve 2 works, most of the materials with the granularity smaller than the sieve pores fall under the sieve, but a part of the materials with the small granularity still remain on the sieve. The sieve mesh specification of the high-frequency material separating sieve 2 in the embodiment is 20 meshes, so the particle size of oversize materials is 5mm-20 meshes, and a small amount of materials below 20 meshes are mixed; the undersize product is the material below 20 meshes.
The oversize material outlet of the high-frequency material separating sieve 2 is connected with the first water flow swirler 5 through the first ultrasonic cleaning chute 3, and the undersize material outlet of the high-frequency material separating sieve 2 is connected with the second water flow swirler 6 through the second ultrasonic cleaning chute 4. The ultrasonic cleaning chute can carry out ultrasonic cleaning to the material, makes tiny particle and large granule separation. The ultrasonic cleaning flow groove is also obliquely arranged, and one end connected with the high-frequency material separating sieve 2 is higher than one end connected with the water flow swirler, so that the materials are transferred and cleaned at the same time by utilizing the fall and the impulsive force of water flow. At the end of the ultrasonic cleaning chute (the end connected with the water flow cyclone), the large and small particle materials are fully separated and are in a state of being tiled and flowing downwards.
The water cyclone includes a bracket, a first motor 101, a first decelerator 102, a tub 105, a connecting rod 104, a paddle 106, a conveying pipe 110, a screw conveyor 111, a second decelerator 113, and a second motor 114. The bracket is used for connecting the structures or devices except the bracket into a whole, and is provided with a channel steel 103, and the channel steel 103 transversely spans over the barrel body 105 and is used for installing the first motor 101 and the first speed reducer 102. The first motor 101 is a frequency-modulation speed-regulation motor, is arranged on the channel steel 103, and can be directly and fixedly connected with the channel steel 103 or indirectly connected with the channel steel 103. The first reducer 102 is mounted on the channel steel 103, and can be directly and fixedly connected with the channel steel 103 or indirectly connected with the channel steel 103. In this embodiment, the first speed reducer 102 is fixed to the channel 103, and the first motor 101 is fixed to the first speed reducer 102, so that the first speed reducer 102 and the channel 103 are indirectly connected. The motor shaft of the first motor 101 is connected to the input shaft of the first reduction gear 102, for example, by a coupling. The output shaft of the first reducer 102 faces the barrel 105; typically, the output shaft is collinear with the axis of rotation of barrel 105. The tub 105 has a certain volume, and the tub wall has a certain strength. The upper section of the barrel body 105 is cylindrical, materials mixed with water are separated, meanwhile, the blades 106 are installed at the upper section, and the light materials are upwards supported by buoyancy generated by the blades 106; the lower section is funnel-shaped, and the deposited heavy materials are collected. A first feeding hole 115 and a first discharging hole 116 are formed in the side surface of the upper part of the barrel body 105, and a second discharging hole 107 is formed in the lower part; the first feed port 115 is connected with an ultrasonic chute of the assembly line; the first discharge port 116 is located at the opposite side of the first feed port 115, one end of the first discharge port 116 close to the barrel 105 is in a duckbill shape, and the other end is in a necking structure and is used for discharging water and light materials in the water; the second discharge port 107 is used for discharging the deposited heavy materials. The connecting rod 104 is substantially a vertically-arranged rotating shaft, is arranged in the barrel body and is collinear with the axis of the barrel body 105, and the upper end of the connecting rod is connected with the output shaft of the first speed reducer 102 and rotates around the axis of the first speed reducer under the driving of the first motor 101. The lower end is provided with a plurality of paddles 106, and the plurality of paddles 106 are evenly distributed around the circumference of the connecting rod 104. The blades 106 are similar to fans or propellers and are rotated to act on the water to cause the water to surge upwards, thereby applying an upward buoyancy to the material in the water (the resultant of the buoyancy of the water to which the material is subjected and the force of the fluid surging the water). The conveying pipe 110, the screw conveyor 111, the second decelerator 113, and the second motor 114 constitute an obliquely arranged pipe conveyor. The conveying pipeline 110 is obliquely arranged, the lower part of the conveying pipeline is provided with a second feeding hole 109, the upper part of the conveying pipeline is provided with a third discharging hole 112, and the height of the third discharging hole 112 is not lower than that of the first discharging hole 116 and/or the first feeding hole 115, so that the second discharging hole 107 at the bottom of the barrel body 105 is prevented from generating suction force on water in the barrel; the second discharge port 107 sets up downwards, and second feed inlet 109 sets up upwards, and second feed inlet 109 passes through flange 108 sealing connection with second discharge port 107. The screw conveyor 111 is disposed along the length direction of the conveying pipe 110, and the upper end thereof is in transmission connection with a second motor 114. The second speed reducer 113 is fixed at the upper end of the conveying pipeline 110, and the second motor 114 is indirectly fixed with the conveying pipeline 110 through the second speed reducer 113; an input shaft of the second speed reducer 113 is connected with a motor shaft of the second motor 114, and an output shaft of the second speed reducer 113 is connected with the upper end of the screw conveyor 111; the second motor 114 is also a fm motor. Materials enter the barrel body 105 at a certain flow rate, and because the water flow has a certain flow rate, and the water flow direction in the barrel is only provided with one water outlet (the first discharge port 116 is indicated, and the height of the second discharge port 107 is not higher than that of the third discharge port 112, the second discharge port 107 does not freely discharge water flow downwards like the lower discharge port in the prior art to form suction force on the materials, and the second discharge port 107 is used for transferring heavy materials under the action of a pipeline conveyor), and in addition, the buoyancy generated by the blades 106 discharges the light materials along with the water from the first discharge port 116 to enter the next processing procedure; the rotating speed of the paddle 106 is controlled by the first motor 101, and after the variable frequency speed regulation of the first motor 101, the buoyancy generated by the paddle 106 can be regulated, so that the specific gravity range of the material can be selected in a certain range (the heavy weight and the light weight are relatively speaking, the faster the rotating speed of the paddle 106 is, the larger the buoyancy is, the more the so-called light weight material is); heavy materials are deposited on the bottom of the barrel body 105, and the heavy materials are transferred and output under the action of the pipeline conveyor, so that light materials and heavy materials are output from different directions. On one hand, the first motor 101 is adopted to drive the paddle 106 to generate buoyancy, and the second discharge hole 107 does not generate suction, so that the light materials and the heavy materials are efficiently separated, and the separation is more thorough; on the other hand, the rotational speed of the paddles 106 is adjustable, so that a range of specific gravity materials can be discharged as light materials from the first discharge port 116, and the rest as heavy materials are discharged through the second discharge port 107, thereby achieving the effect of selective separation (different hydrocyclones identify different light and heavy materials, which is determined by the rotational speed of the paddles 10).
