Description

Technical Field

[0001] The present invention relates to the technical field of cyclones, and in particular to a hydrocyclone device. Background Art

[0002] Slurry refers to a liquid mixture formed by adding water and other auxiliary materials to solid raw materials such as ore and mineral soil in order to extract target elements in industrial production. In the chemical mineral processing process, in order to ensure the required slurry mass fraction during leaching, a concentration operation is usually set before leaching. The slurry after leaching and the slurry after chemical precipitation need to be separated into solid and liquid phases to meet the requirements of subsequent operations. In the concentration operation, hydrocyclone is a commonly used and important equipment.

[0003] When the ore pulp is concentrated, the hydrocyclone is used to separate and remove the heavier coarse particles of mud and sand in the ore pulp. After the ore pulp is introduced into the hydrocyclone for treatment, the heavier coarse particles of mud and sand in the ore pulp are released from the discharge pipe at the bottom of the hydrocyclone, and the concentrated ore pulp flows out from the overflow pipe at the upper end of the hydrocyclone. When the coarse particles of mud and sand are released from the discharge pipe, if there are too many coarse particles of mud and sand in the ore pulp, more coarse particles of mud and sand will roll to the upper end of the discharge pipe. Due to the reduced diameter of the discharge pipe, the coarse particles of mud and sand cannot be quickly introduced. , causing more coarse mud and sand to easily accumulate at the upper end of the discharge pipe, blocking the upper end of the discharge pipe, making it impossible for the coarse mud and sand to be released from the discharge pipe, and because the discharge pipe is in a static state, when the coarse mud and sand are discharged from the discharge pipe, part of the mud and sand adheres to the inner wall of the discharge pipe, thereby reducing the channel area in the discharge pipe and causing blockage in the discharge pipe. After the mud and sand block the discharge pipe, the inner wall of the discharge pipe is worn and corroded, thereby accelerating the wear rate of the discharge pipe, thereby reducing the service life of the discharge pipe and reducing the service life of the equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art that a large amount of coarse-grained mud and sand are easily accumulated on the upper end of the discharge pipe, blocking the upper end of the discharge pipe, and part of the mud and sand adhere to the inner wall of the discharge pipe, thereby reducing the channel area in the discharge pipe and causing blockage in the discharge pipe, and a hydrocyclone device is proposed.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figure 1-2 A hydrocyclone device comprises a conical shell 1, the upper end of the conical shell 1 is connected with a straight cylinder, the upper end of the straight cylinder is connected with an overflow pipe, the straight cylinder is connected with a feed pipe, the bottom end of the conical shell 1 is connected with a discharge pipe 2, the inner wall of the discharge pipe 2 is provided with a groove, a mounting frame 3 is fixedly connected to the conical shell 1, a reduction motor 4 is fixedly connected to the mounting frame 3, a first gear 5 is fixedly connected to the output end of the reduction motor 4, a rotating tube 6 is rotatably connected to the mounting frame 3, the upper end of the rotating tube 6 cooperates with the groove, a second gear 7 is fixedly connected to the rotating tube 6, the second gear 7 is meshed with the first gear 5, and a pushing mechanism 8 is connected to the rotating tube 6 for preventing slag from accumulating and clogging at the connection between the conical shell 1 and the discharge pipe 2.

[0026] Working principle:

[0027] The ore slurry is introduced into the straight cylinder through the feed pipe at a certain speed. As the ore slurry in the straight cylinder gradually increases, the ore slurry forms a vortex state in the straight cylinder and the conical shell 1. The particle debris in the ore slurry vortexes and rolls along the inner wall of the conical shell 1 toward the discharge pipe 2. The ore slurry in the straight cylinder flows out from the overflow pipe. Since the rotating pipe 6 is located in the discharge pipe 2, the particle debris falling from the bottom end of the conical shell 1 falls into the rotating pipe 6 and is released from the bottom end of the rotating pipe 6, completing the removal of the particle debris in the ore slurry.

[0028] The reduction motor 4 is powered on and started. After the reduction motor 4 is started, it drives the first gear 5 to rotate, and the first gear 5 drives the second gear 7 to rotate. Through the coordination of the number of teeth between the first gear 5 and the second gear 7, the second gear 7 drives the rotating tube 6 to rotate at a certain speed. The rotation direction of the rotating tube 6 is consistent with the slurry vortex direction in the conical shell 1. The particulate debris falling into the rotating tube 6 collides with the inner wall of the rotating tube 6. Since the rotating tube 6 is in a rotating state, the particulate debris discharged from the rotating tube 6 contains a certain amount of slurry. The slurry is released along the length direction of the rotating tube 6. After the rotating tube 6 rotates, it is tangent to the released slurry. A tangential force is generated between the slurry and the inner wall of the rotating tube 6. The tangential force is generated to impact the inner wall of the rotating tube 6, so that the particulate debris cannot adhere to the inner wall of the rotating tube 6, thereby not causing the inner wall of the rotating tube 6 to be blocked.

[0029] At the same time, the rotating tube 6 drives the pushing mechanism 8 to rotate, and the pushing mechanism 8 rotates with the rotating tube 6. After the pushing mechanism 8 rotates, the connection between the conical shell 1 and the discharge pipe 2 is stirred, so that the granular debris at the connection between the conical shell 1 and the discharge pipe 2 is scattered, and the scattered granular debris gradually enters the discharge pipe 2, and will not block the upper end of the discharge pipe 2. When the slurry is processed, the sorted granular debris can be continuously released without causing blockage. After the granular debris is discharged, it will not adhere to the inner wall of the discharge pipe 2, thereby not causing wear and corrosion to the discharge pipe 2, reducing the wear on the inner wall of the discharge pipe 2, thereby extending the service life of the discharge pipe 2, and extending the service life of the equipment.

[0030] Embodiment 2: In embodiment 1, during the process of stirring the connection between the conical shell 1 and the discharge pipe 2 by the pushing mechanism 8 to prevent blockage, the conical shell 1 and the discharge pipe 2 are not blocked after stirring, and the pushing mechanism 8 continues to stir the connection between the conical shell 1 and the discharge pipe 2, causing a part of the granular debris at the connection between the conical shell 1 and the discharge pipe 2 to move upward along the conical shell 1 during the stirring process, and the granular debris moving upward collides with the granular debris on the inner wall of the conical shell 1 that moves downward, thereby preventing the granular debris on the inner wall of the conical shell 1 from moving downward, refer to Figure 3-7As another preferred embodiment of the present invention, on the basis of embodiment 1, the pushing mechanism 8 includes a first perforated plate 81, the first perforated plate 81 is fixedly connected to the rotating tube 6, a movable rod 83 is slidably inserted on the first perforated plate 81, one end of the movable rod 83 is fixedly connected to a push rod 84, the push rod 84 is located in the rotating tube 6 and contacts the inner wall of the rotating tube 6, the upper end of the push rod 84 extends out of the upper end of the rotating tube 6, and the upper end of the push rod 84 is inclined toward the axial center line direction of the rotating tube 6, the movable rod 83 is fixedly connected to a second perforated plate 82, the second perforated plate 82 is slidably connected to the rotating tube 6, the upper end of the first perforated plate 81 is fixedly connected to a first spring 85, one end of the first spring 85 is fixedly connected to the lower surface of the second perforated plate 82, the other end of the movable rod 83 is connected to a pulley 86, and the bottom end of the mounting frame 3 is fixedly connected to a support ring 87, the bottom end of the support ring 87 is provided with an inclined surface, and the pulley 86 contacts the inclined surface.

[0031] Working principle:

[0032] The rotating tube 6 drives the first perforated plate 81 to rotate, the first perforated plate 81 drives the movable rod 83 to rotate, the movable rod 83 drives the push rod 84 to rotate, and after the push rod 84 rotates, it stirs the connection between the conical shell 1 and the discharge pipe 2, so that the particles and debris at the connection between the conical shell 1 and the discharge pipe 2 are scattered and will not block the upper end of the discharge pipe 2. The movable rod 83 also drives the pulley 86 to rotate, and the pulley 86 rolls on the inclined surface during the rotation. Since the bottom end of the support ring 87 is a slope structure, the distance between each position on the slope and the mounting frame is 3. When the pulley 86 rolls on the inclined plane, the distance between the position of the pulley 86 on the inclined plane and the bottom end surface of the mounting frame 3 is the smallest at the beginning. As the pulley 86 rotates along with the rotating tube 6, it gradually moves to the position on the inclined plane where the distance from the bottom end surface of the mounting frame 3 is the largest, and then moves from the position with the largest distance to the position with the smallest distance. When the pulley 86 rolls one circle, the distance between the position with the smallest distance from the bottom end of the mounting frame 3 and the position with the largest distance from the bottom end of the mounting frame 3 is half a circle of the inclined plane.

[0033] When the pulley 86 moves from the minimum position to the maximum position at the bottom of the mounting frame 3, the pulley 86 also moves downward during the rolling process of the inclined surface, and the pulley 86 drives the movable rod 83 to move downward, and the movable rod 83 drives the second perforated plate 82 to move downward. After the second perforated plate 82 moves downward, it squeezes the first spring 85, and the first spring 85 generates elastic force after being compressed. The movable rod 83 also drives the push rod 84 to move downward. After the push rod 84 moves downward, the upper end of the push rod 84 gradually retracts into the rotating tube 6. In the process of gradually retracting the upper end of 84 into the rotating tube 6, the upper end of the push rod 84 stirs the connection between the conical shell 1 and the discharge tube 2. When the pulley 86 rolls to the midpoint between the minimum position and the maximum position, that is, the position of a quarter of a circle of the inclined surface, the upper end of the push rod 84 is flush with the upper end of the rotating tube 6. When the pulley 86 continues to move to the maximum position, the upper end of the push rod 84 retracts into the rotating tube 6. At this time, the upper end of the push rod 84 does not stir the connection between the conical shell 1 and the discharge tube 2.

[0034] When the pulley 86 moves from the maximum distance value position to the minimum distance value position, under the elastic force of the first spring 85, the first spring 85 pushes the second perforated plate 82 to move upward, and the second perforated plate 82 drives the movable rod 83 to move upward, and the movable rod 83 drives the pulley 86 to move upward, so that the pulley 86 is in close contact with the inclined surface, and the movable rod 83 also drives the push rod 84 to move upward. When the pulley 86 rolls to the midpoint position between the minimum value position and the maximum value position, that is, the position of a quarter of a circle of the inclined surface, the upper end of the push rod 84 is flush with the upper end of the rotating tube 6. During the movement of the push rod 84, the upper end of the push rod 84 will not stir the connection between the conical shell 1 and the discharge pipe 2. After the pulley 86 continues to roll, the upper end of the push rod 84 gradually extends out of the upper end of the rotating tube 6.

[0035] During the process of the rotating tube 6 driving the push rod 84 to rotate, for every rotation of the rotating tube 6, the upper end of the push rod 84 is extended out of the upper end of the rotating tube 6 for half a circle to stir the connection between the conical shell 1 and the discharge pipe 2 to prevent particulate debris from accumulating at the connection between the conical shell 1 and the discharge pipe 2, and the other half a circle is retracted into the rotating tube 6 without stirring the connection between the conical shell 1 and the discharge pipe 2, thereby reducing the stirring time, thereby reducing the amount of particulate debris moving upward due to collision with the upper end of the push rod 84, thereby reducing the collision of the upward-moving particulate debris with the downward-moving particulate debris on the inner wall of the conical shell 1, and reducing the obstruction to the downward movement of particulate debris on the inner wall of the conical shell 1.

[0036] Embodiment 3: In embodiment 2, since the push rod 84 is a round rod, a notch is formed between the outer wall of the push rod 84 and the inner wall of the rotating tube 6, and a gap is generated between the push rod 84 and the inner wall of the rotating tube 6. When the particles are discharged from the rotating tube 6, some of the particles will fall into the notch and the gap. During the vertical movement of the push rod 84, the particles in the notch and the gap will be squeezed. The particles in the notch and the gap will scratch the inner wall of the rotating tube 6, accelerating the wear rate of the rotating tube 6, thereby reducing the service life of the rotating tube 6. Figure 8-9 As another preferred embodiment of the present invention, on the basis of Embodiment 2, the push rod 84 is connected with an anti-scratch mechanism 9 for reducing scratches on the inner wall of the rotating tube 6, the anti-scratch mechanism 9 includes a movable plate 91, a movable groove 92 is provided on the push rod 84, the movable plate 91 is slidably connected to the movable groove 92, a connecting rod 93 is fixedly connected to the movable plate 91, a through hole 94 is provided on the movable groove 92, the connecting rod 93 is plugged into the through hole 94, a second spring 96 is fixedly connected to the movable plate 91, one end of the second spring 96 is fixedly connected to the movable groove 92, a sealing block 95 is fixedly connected to the movable plate 91, the sealing block 95 extends out of the movable groove 92 and contacts the inner wall of the rotating tube 6, and flat surfaces are provided on both sides of the sealing block 95, and the flat surfaces are perpendicular to the inner wall of the rotating tube 6.

[0037] Working principle:

[0038] The sealing block 95 contacts the inner wall of the rotating tube 6, and the inner wall of the rotating tube 6 limits and squeezes the sealing block 95. The sealing block 95 squeezes the movable plate 91, and the movable plate 91 moves smoothly under the guidance of the connecting rod 93. After the movable plate 91 moves, it squeezes the second spring 96. The second spring 96 generates an elastic force after being compressed. The elastic force generated by the second spring 96 squeezes the sealing block 95 through the movable plate 91, so that the sealing block 95 is in close contact with the inner wall of the rotating tube 6. The sealing block 95 seals the gap between the push rod 84 and the inner wall of the rotating tube 6, so that particulate debris will not fall between the push rod 84 and the inner wall of the rotating tube 6, and the two sides of the sealing block 95 are flat surfaces, which are perpendicular to the inner wall of the rotating tube 6. No grooves are formed between the two sides of the sealing block 95 and the inner wall of the rotating tube 6. During the vertical movement of the push rod 84, the push rod 84 will not squeeze particulate debris, thereby not causing scratches on the inner wall of the rotating tube 6, slowing down the wear rate of the rotating tube 6, thereby extending the service life of the rotating tube 6.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
