Description

Technical Field

[0001] This utility model relates to the field of particle sorting technology, specifically to a cyclone microparticle sorting device with adjustable particle size. Background Technology

[0002] Currently, environmental factors are playing an increasingly important role in resource exploration, efficient mining, and comprehensive utilization technologies. Therefore, in coal production, waste recycling, and mineral processing, it is necessary to separate solid mixtures based on their different characteristics. Depending on the separation principle, the main separation methods include screening, air classification, flotation, electrostatic separation, and magnetic separation. Except for screening, which separates solids based on particle size, the other methods rely on the density, charge, and magnetic properties of the solid particles. In our daily lives, industrial and agricultural production, and scientific research, it is often necessary to separate mixtures of solid particles with similar density, magnetic properties, and charge characteristics but containing different particle sizes (based solely on their particle size differences) to obtain solid particles of different sizes to meet the needs of production and scientific research. This is also relevant to technologies for the comprehensive utilization of low-grade resources and tailings resources.

[0003] When performing sorting, it is often necessary to separate solid particles with the same density, magnetic properties, and electrical properties but different particle sizes. Currently, the main methods that can meet this sorting requirement are hydraulic separation, wind separation, and sieving. For the separation of fine and extremely fine particles, the principle of hydrocyclone is generally used. However, in the existing technology, it is necessary to disassemble and replace the hydrocyclone or settling port when adjusting the sorting level, which is troublesome to operate and inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a cyclone microparticle sorting device with adjustable particle size, which features online adjustment of the classification particle size as needed, convenient operation, and simple structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable particle size hydrocyclone fine particle sorting device, comprising a stirrer and a hydrocyclone, wherein an end platform is fixedly connected to the top of the hydrocyclone, a through groove is formed on the upper end face of the end platform, a rotating cylinder is rotatably connected inside the through groove, an overflow pipe is rotatably connected to the inner side of the rotating cylinder, a spiral groove is formed through the outer wall of the rotating cylinder, a limiting block extending to the outside of the spiral groove is fixedly connected to the outer wall of the overflow pipe, a feed inlet is connected to the side wall of the hydrocyclone, and a discharge outlet is connected to the bottom of the hydrocyclone.

[0006] In order to limit the positioning block, as a preferred embodiment of the adjustable particle size cyclone microparticle sorting device of this utility model, the inner wall of the through groove is provided with a vertically arranged slot, the width of which matches the positioning block.

[0007] To facilitate material feeding, in a preferred embodiment of the adjustable particle size cyclone microparticle sorting device of this utility model, a material guide pipe is connected between the discharge port and the feed port of the agitator, and a slurry pump is provided on the outer wall of the material guide pipe.

[0008] In order to collect coarse particles, as a preferred embodiment of the adjustable particle size cyclone microparticle sorting device of this invention, a settling tank is provided below the cyclone separator.

[0009] In order to collect fine particulate media, as a preferred embodiment of the adjustable particle size hydrocyclone micro-particle sorting device of this utility model, an overflow tank is provided on the side of the hydrocyclone away from the agitator, and a connecting pipe is connected between the overflow tank and the overflow pipe.

[0010] In order to rotate the rotating drum, as a preferred embodiment of the adjustable particle size cyclone microparticle sorting device of this utility model, a knob is fixedly connected to the upper end face of the rotating drum.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The solid particles to be separated are uniformly mixed with water using a stirrer. The slurry pump is then started, pumping the uniformly mixed medium into a hydrocyclone. Under centrifugal force, the slurry separates into heavier coarse particles and lighter fine particles. The fine particles rise along the central axis of the hydrocyclone to the overflow pipe and are then discharged into the overflow tank via a connecting pipe. The heavier coarse particles flow down the side wall to the discharge port and are collected in the settling tank below. Turning the knob rotates the drum, which in turn rotates the spiral groove on its outer wall. A limiting block fixed to the outer wall of the overflow pipe extends into the spiral groove. As the spiral groove rotates, the limiting block moves along the spiral groove's trajectory. The limiting block is also limited by a slot, ensuring it can only move vertically. Therefore, rotating the drum moves the overflow pipe up and down, allowing adjustment of the overflow pipe's insertion depth as needed. This adapts to changes in medium particle size distribution and the requirements of classification indicators, enabling online adjustment of the classification particle size. The structure is simple and easy to operate. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figures 1 to 3 An adjustable particle size hydrocyclone fine particle sorting device includes a stirrer 1 and a hydrocyclone 2. The top of the hydrocyclone 2 is fixedly connected to an end platform 3. A through groove 4 is opened through the upper end face of the end platform 3. A rotating cylinder 5 is rotatably connected inside the through groove 4. An overflow pipe 6 is rotatably connected to the inner side of the rotating cylinder 5. A spiral groove 7 is opened through the outer wall of the rotating cylinder 5. A limiting block 8 extending to the outside of the spiral groove 7 is fixedly connected to the outer wall of the overflow pipe 6. A feed inlet 9 is connected to the side wall of the hydrocyclone 2. A discharge outlet 10 is connected to the bottom of the hydrocyclone 2.

[0019] In this embodiment: the solid particles to be separated and the water medium are mixed evenly by the agitator 1, the slurry pump 13 is started, and the evenly mixed medium is pumped into the hydrocyclone 2. Under the action of centrifugal force, the slurry is separated into two parts: heavier coarse particles and lighter fine particles. The fine particles rise along the central axis of the hydrocyclone 2 to the overflow pipe 6 and are then discharged into the overflow tank 15 through the connecting pipe 16. The heavier coarse particles flow along the side wall to the discharge port 10 below and are discharged, thus entering the settling tank 14 below for collection. When the knob 17 is turned, the rotating drum 5 is driven to rotate. The rotation of the rotating drum 5 drives the spiral groove 7 on its outer wall to rotate. The limiting block 8, which is fixed to the outer wall of the overflow pipe 6, extends into the interior of the spiral groove 7. Thus, when the spiral groove 7 rotates, the limiting block 8 moves along the trajectory of the spiral groove 7. The limiting block 8 is limited by the slot 11, so that the limiting block 8 can only move in the vertical direction. Therefore, when the rotating drum 5 is rotated, the overflow pipe 6 is driven to move up and down. Thus, the insertion depth of the overflow pipe 6 can be adjusted as needed, which is more adaptable to changes in the particle size composition of the medium and the requirements of the classification index, and allows for online adjustment of the classification particle size.

[0020] As a technical optimization of this utility model, the inner wall of the through groove 4 is provided with a vertically arranged slot 11, the width of which matches the limiting block 8.

[0021] In this embodiment: the width of the slot 11 matches the limit block 8, and the limit block 8 is limited by the slot 11, so that the limit block 8 can only move in the vertical direction.

[0022] As a technical optimization of this utility model, a guide pipe 12 is connected between the discharge port and the inlet port 9 of the agitator 1, and a slurry pump 13 is provided on the outer wall of the guide pipe 12.

[0023] In this embodiment: a guide pipe 12 is connected between the discharge port and the feed port 9 of the agitator 1. The slurry pump 13 is started to facilitate the introduction of the mixed medium into the hydrocyclone 2.

[0024] As a technical optimization of this utility model, a settling tank 14 is provided below the hydrocyclone 2.

[0025] In this embodiment, a settling tank 14 is provided below the hydrocyclone 2. Heavier coarse particles flow along the side wall to the discharge port 10 below and are discharged, thereby entering the settling tank 14 below for collection.

[0026] As a technical optimization of this utility model, an overflow tank 15 is provided on the side of the hydrocyclone 2 away from the agitator 1, and a connecting pipe 16 connects the overflow tank 15 and the overflow pipe 6.

[0027] In this embodiment, fine particles rise along the central axis of the hydrocyclone 2 to the overflow pipe 6 and are then discharged into the overflow tank 15 through the connecting pipe 16.

[0028] As a technical optimization of this utility model, a knob 17 is fixedly connected to the upper end face of the rotating drum 5.

[0029] In this embodiment, a knob 17 is fixedly connected to the upper end face of the rotating drum 5 to facilitate the rotation of the rotating drum 5.

[0030] Working principle:

[0031] The solid particles to be separated and the water medium are mixed evenly by the agitator 1. The slurry pump 13 is started and the evenly mixed medium is pumped into the hydrocyclone 2. Under the action of centrifugal force, the slurry is separated into two parts: heavier coarse particles and lighter fine particles. The fine particles rise along the central axis of the hydrocyclone 2 to the overflow pipe 6 and are then discharged into the overflow tank 15 through the connecting pipe 16. The heavier coarse particles flow down the side wall to the discharge port 10 and are discharged into the settling tank 14 below for collection. When the knob 17 is turned, the rotating drum 5 is driven to rotate. The rotation of the rotating drum 5 drives the spiral groove 7 on its outer wall to rotate. The limiting block 8, which is fixed to the outer wall of the overflow pipe 6, extends into the interior of the spiral groove 7. Thus, when the spiral groove 7 rotates, the limiting block 8 moves along the trajectory of the spiral groove 7. The limiting block 8 is limited by the slot 11, so that the limiting block 8 can only move in the vertical direction. Therefore, when the rotating drum 5 is rotated, the overflow pipe 6 is driven to move up and down. Thus, the insertion depth of the overflow pipe 6 can be adjusted as needed, which is more adaptable to changes in the particle size composition of the medium and the requirements of the classification index, and allows for online adjustment of the classification particle size.
