Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone technology, and in particular to a quartz sand classifying hydrocyclone. Background Technology

[0002] A hydrocyclone is a static device that uses centrifugal force and fluid dynamics to separate, classify, or concentrate solid particles, droplets, or components of different densities in a mixture. Its core feature is the absence of moving parts; it relies on the fluid's own pressure to generate a high-speed rotating flow field, achieving efficient separation. A quartz sand grading hydrocyclone is specifically designed for quartz sand particle size classification. It separates quartz sand particles according to different particle size ranges using centrifugal force and is widely used in industries such as mineral processing, glass, ceramics, and photovoltaic silicon materials.

[0003] To this end, the patent with announcement number CN202070421U discloses a hydrocyclone, which in particular relates to a hydraulic hydrocyclone: ​​The hydraulic hydrocyclone of this utility model can adjust the resistance of the settling nozzle: wherein: it includes a settling nozzle and an adjusting sleeve, the adjusting sleeve is located at the lower part of the settling nozzle, and a handle for controlling the up and down movement of the adjusting sleeve is provided on the side walls on both sides of the adjusting sleeve.

[0004] The hydrocyclones mentioned above only adjust the separation effect through the resistance of the settling nozzle during use, lacking a mechanism to actively enhance centrifugal force. This results in low classification efficiency for fine particles, and the adjustment range is limited by the sleeve stroke, making it difficult to adapt to extreme particle sizes and affecting the classification effect. Utility Model Content

[0005] The purpose of this invention is to provide a quartz sand grading hydrocyclone to solve the problem of existing hydrocyclones that are not conducive to enhancing centrifugal force.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quartz sand grading hydrocyclone, comprising a first cylinder;

[0007] A feed pipe is fixed to one side of the top of the first cylinder, an overflow pipe is fixed to the top of the first cylinder, a second cylinder is installed at the bottom of the first cylinder, and connecting flanges are fixed to both the bottom of the first cylinder and the top of the second cylinder. A rotating structure is installed inside the second cylinder, the rotating structure includes a motor fixed to one side of the second cylinder, a first rotating shaft is fixed to the output end of the motor, a first bevel gear is fixed to one end of the first rotating shaft inside the second cylinder, a second rotating shaft is installed inside the second cylinder, a second bevel gear is fixed to the outside of the second rotating shaft, a bracket is fixed inside the second cylinder, a turntable is fixed to the top of the second rotating shaft inside the first cylinder, a vortex propeller is fixed to the outside of the turntable, and a spiral blade is fixed to the bottom of the second rotating shaft.

[0008] An adjustment structure is fixed at the bottom of the second cylinder.

[0009] Preferably, one end of the first rotating shaft extends through one side of the second cylinder into the interior of the second cylinder and is fixedly connected to one end of the first bevel gear. A sealing ring is installed inside the second cylinder outside the first rotating shaft, and the first bevel gear and the second bevel gear are meshed together.

[0010] With the above structure, during use, the first rotating shaft passes through the second cylinder via a sealing ring, ensuring that power is transmitted from the motor to the inside while preventing slurry leakage and ensuring the equipment's airtightness. Furthermore, through the meshing connection of the first and second bevel gears, the horizontal axial rotation is converted into vertical axial rotation, driving the second rotating shaft and cyclone propeller to rotate at high speed, actively strengthening the centrifugal force field, and improving the separation efficiency of coarse and fine particles.

[0011] Preferably, the bracket is arranged in a cross shape, and a through hole is provided at the center of the bracket. A limit block is fixed on the outside of the second rotating shaft at the top of the bracket, and the second rotating shaft is rotatably connected inside the bracket.

[0012] With the above structure, the cross-shaped structure of the bracket provides multi-directional uniform force support for the second rotating shaft during use, effectively suppressing shaft vibration during high-speed rotation, avoiding abnormal wear of the equipment caused by shaft wobble, the limiting block can prevent the second rotating shaft from axial movement under high-speed rotation or slurry impact, and the central through hole ensures that the second rotating shaft is always in the center position of the hydrocyclone, maintaining the rotational symmetry of the hydrocyclone and ensuring uniform distribution of the centrifugal force field.

[0013] Preferably, the swirl propellers are evenly distributed on the outer side of the turntable, and the outer diameter of the helical blades is smaller than the inner diameter of the bottom of the second cylinder.

[0014] With the above structure, the cyclone propellers are evenly distributed during use, ensuring that they apply a uniform force to the slurry when rotating. This enhances the stability of the centrifugal force field, allowing the quartz sand particles to separate more orderly under the action of centrifugal force, improving the classification efficiency, and increasing the classification accuracy of coarse and fine particles. Furthermore, since the outer diameter of the spiral blades is smaller than the inner diameter of the bottom of the second cylinder, it provides sufficient space for the discharge of coarse sand and allows the rotation of the spiral blades to guide the coarse sand to be discharged smoothly downwards.

[0015] Preferably, the adjusting structure includes a through groove fixed to the bottom of the second cylinder, a fixed shell fixed to the outer side of the bottom of the second cylinder, a threaded rod installed inside the fixed shell, a rotating block fixed to one end of the threaded rod outside the fixed shell, a flow-blocking plug installed on the outer side of the threaded rod inside the fixed shell, a threaded groove provided on the outer side of the threaded rod inside the flow-blocking plug, guide rods fixed to both sides inside the fixed shell, a guide hole provided inside the flow-blocking plug outside the guide rod, a sealing ring installed on the outer side of the fixed shell inside the second cylinder, and a limit plate fixed to the outer side of the threaded rod.

[0016] Preferably, the through groove is arranged in a cross shape, the fixing shells are distributed at equal intervals on the outer side of the bottom of the second cylinder, and the interior of the fixing shell is connected to the interior of the second cylinder.

[0017] With the above structure, the underflow can be discharged more evenly through the cross-shaped channel during use, and the flow-blocking plug inside the fixed shell, in conjunction with the cross-shaped channel, can achieve all-round and uniform adjustment of the underflow discharge.

[0018] Preferably, the threaded rod and the flow-blocking plug are connected by a threaded groove, the flow-blocking plug and the guide rod are connected by a guide hole, and the length of the flow-blocking plug is the same as the radius of the bottom end of the second cylinder.

[0019] With the above structure, the position of the flow-blocking plug can be easily adjusted during use, thereby adjusting the opening and closing degree of the through groove. The flow-blocking plug and the guide rod are slidably connected through the guide hole, providing a stable guide for the movement of the flow-blocking plug and preventing the flow-blocking plug from deviating or shaking. The length of the flow-blocking plug is the same as the radius of the bottom end of the second cylinder, so that the flow-blocking plug can completely cover the opening of the through groove in the second cylinder, thereby closing the through groove.

[0020] The advantages of the quartz sand classifying hydrocyclone provided by this utility model are as follows:

[0021] By incorporating a rotating structure, the centrifugal force is enhanced by the rotation of the motor-driven cyclone propeller, resulting in more thorough separation of quartz sand particles, improved grading accuracy of coarse and fine particles, and smooth downward discharge of coarse sand through the rotation of the spiral blades, avoiding sedimentation and blockage, and extending the service life of the equipment.

[0022] By incorporating an adjustable structure and adjusting the threaded rod in real time to change the position of the flow-blocking plug, the opening and closing degree of the channel can be easily adjusted, allowing dynamic control of the underflow discharge speed to adapt to different particle size requirements and ensuring that the graded quartz sand meets industrial standards.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 The present invention provides a quartz sand grading hydrocyclone, comprising a first cylinder 1.

[0031] Reference Figure 1 , Figure 2 and Figure 5As shown, a feed pipe 2 is fixed to one side of the top of the first cylinder 1, an overflow pipe 3 is fixed to the top of the first cylinder 1, a second cylinder 4 is installed at the bottom of the first cylinder 1, and connecting flanges 5 are fixed to both the bottom of the first cylinder 1 and the top of the second cylinder 4. A rotating structure 6 is installed inside the second cylinder 4. The rotating structure 6 includes a motor 601 fixed to one side of the second cylinder 4. A first rotating shaft 602 is fixed to the output end of the motor 601. A first bevel gear 603 is fixed to one end of the first rotating shaft 602 inside the second cylinder 4. A second rotating shaft 604 is installed inside the second cylinder 4. A second bevel gear 605 is fixed to the outside of the second rotating shaft 604. A bracket 606 is fixed inside the second cylinder 4. A turntable 607 is fixed to the top of the second rotating shaft 604 inside the first cylinder 1. A swirl propeller 608 is fixed to the outside of the turntable 607. A spiral blade 609 is fixed to the bottom of the second rotating shaft 604. One end of the first rotating shaft 602 extends through one side of the second cylinder 4 into the interior of the second cylinder 4 and is fixedly connected to one end of the first bevel gear 603. A sealing ring is installed inside the second cylinder 4 outside the first rotating shaft 602. The first bevel gear 603 and the second bevel gear 605 are meshed. The bracket 606 is arranged in a cross shape. A through hole is provided at the center position inside the bracket 606. Limit blocks are fixed to the outside of the second rotating shaft 604 at the top of the bracket 606. The second rotating shaft 604 is rotatably connected inside the bracket 606. The swirl propellers 608 are evenly distributed on the outside of the turntable 607. The outer diameter of the spiral blade 609 is smaller than the inner diameter of the bottom of the second cylinder 4.

[0032] Quartz sand slurry enters the first cylinder 1 tangentially through the feed pipe 2 at a certain pressure, forming a high-speed rotating vortex. The motor 601 drives the first rotating shaft 602 to rotate, and the meshing connection of the first bevel gear 603 and the second bevel gear 605 drives the second rotating shaft 604 to rotate, which in turn causes the turntable 607 and the cyclone propeller 608 to rotate at high speed. This makes the cyclone propeller 608 further enhance the rotational motion of the slurry and improve the centrifugal separation efficiency. Under the action of centrifugal force, the denser coarse quartz sand particles are thrown towards the cylinder wall and move downwards along the wall in a spiral. The fine particles, due to the smaller centrifugal force, are concentrated in the central area of ​​the cyclone separator and discharged outwards through the overflow pipe 3. The rotation of the spiral blade 609 guides the coarse particles downwards to avoid bottom deposition and blockage.

[0033] Reference Figures 1-4As shown, an adjustment structure 7 is fixed to the bottom end of the second cylinder 4. The adjustment structure 7 includes a through groove 701 fixed to the bottom end of the second cylinder 4. A fixed shell 702 is fixed to the outer side of the bottom of the second cylinder 4. A threaded rod 703 is installed inside the fixed shell 702. A rotating block 704 is fixed to one end of the threaded rod 703 on the outer side of the fixed shell 702. A flow-blocking plug 705 is installed on the outer side of the threaded rod 703 inside the fixed shell 702. A threaded groove 706 is provided on the outer side of the threaded rod 703 inside the flow-blocking plug 705. Guide rods 707 are fixed to both sides inside the fixed shell 702. The flow-blocking plug 707 is located on the outer side of the guide rod 707. The interior of the second cylinder 4 is provided with a guide hole 708. A sealing ring 709 is installed on the outside of the fixed shell 702 inside the second cylinder 4. A limit plate 710 is fixed on the outside of the threaded rod 703. The through groove 701 is arranged in a cross shape. The fixed shells 702 are evenly distributed on the outside of the bottom of the second cylinder 4. The interior of the fixed shell 702 is connected to the interior of the second cylinder 4. The threaded rod 703 and the flow-blocking plug 705 are threadedly connected through the threaded groove 706. The flow-blocking plug 705 and the guide rod 707 are slidably connected through the guide hole 708. The length of the flow-blocking plug 705 is the same as the radius of the interior of the bottom end of the second cylinder 4.

[0034] Rotating the rotating block 704 drives the threaded rod 703 to rotate, which in turn causes the flow-blocking plug 705 to slide along the guide rod 707 under the action of the thread. This facilitates the adjustment of the opening and closing degree of the through groove 701, thereby controlling the flow rate and classification accuracy of the underflow discharge, adapting to different particle size requirements, and ensuring that the classified quartz sand meets industrial standards.
