Description

Technical Field

[0001] This utility model belongs to the technical field of gold ore beneficiation equipment, and in particular relates to a stirring device for gold ore beneficiation process. Background Technology

[0002] In gold ore beneficiation, the mixing device is one of the key pieces of equipment. Its main function is to fully mix the gold ore slurry with the beneficiation reagents, creating favorable material conditions for subsequent flotation, leaching and other processes, which directly affects the efficiency and recovery rate of gold ore beneficiation. A Chinese patent application with publication number CN217699600U discloses a stirring device for gold ore beneficiation, including a cylinder, a stirring shaft inside the cylinder, an impeller at one end of the stirring shaft extending into the cylinder, an air aerator at the bottom of the cylinder, and a bubble elimination device on the stirring shaft. The bubble elimination device is used to eliminate bubbles generated in the cylinder. This invention can generate uniform air bubbles through the structure of the air aerator. The upward force of the air bubbles can drive the coarse sand at the bottom of the cylinder to move upward and mix with the upper slurry, thereby avoiding the stratification of coarse and fine slurry during the beneficiation process. Although this patent can reduce slurry stratification by generating bubbles through a bubble refiner structure, it still suffers from low stirring efficiency. While the upward movement of bubbles can drive some fine mineral powder upward to alleviate stratification, this method only affects the fine slurry in a localized area at the bottom of the mixing drum. As the bubbles rise, they gradually disperse, having little impact on the fine slurry in the upper part of the mixing drum. Therefore, it cannot fundamentally solve the problem of fine slurry stratification and will still affect the mixing effect of the slurry and reagents, thereby reducing the gold ore beneficiation recovery rate. To address these issues, we provide a stirring device for gold ore beneficiation processes. Utility Model Content

[0003] The purpose of this invention is to provide a stirring device for gold ore beneficiation processes. By cooperating with the stirring component and the driving component, the invention solves the problem of low stirring efficiency caused by the fixed position of the stirring mechanism in existing gold ore beneficiation stirring devices.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0005] This utility model relates to a stirring device for gold ore beneficiation processes, comprising a base, a stirring cylinder fixedly connected to the top of the base, a top cover provided on the top of the stirring cylinder, a stirring assembly provided on the top of the stirring cylinder, a vertical frame fixedly connected to one side of the top of the base, a driving assembly provided on the top surface of the vertical frame, the driving assembly including a movable sleeve, the inner wall of the movable sleeve contacting the surface of the vertical frame, a fixed plate fixedly connected to the top of one side of the vertical frame, a drive motor fixedly connected to the back of the fixed plate, a cam fixedly connected to the output shaft of the drive motor, an extension plate fixedly connected to one side of the movable sleeve, a connecting plate fixedly connected to the side of the movable sleeve away from the extension plate, a driving sleeve fixedly connected to one side of the connecting plate, springs fixedly connected to both sides of the top of the connecting plate, a top plate fixedly connected to the top of the springs, and one side of the top plate fixedly connected to the surface of the vertical frame.

[0006] The present invention is further configured such that the stirring assembly includes a fixed frame, the surface of the fixed frame is fixedly connected to one side of the connecting plate, a movable disk is fixedly connected to the bottom of the fixed frame, a stirring motor is fixedly connected to one side of the top of the movable disk, a main gear is fixedly connected to the output shaft of the stirring motor, a stirring rod is penetrated through the surface of the top cover, a driven gear is fixedly connected to the top of the surface of the stirring rod, a turntable is fixedly connected to the bottom of the stirring rod, an impeller is fixedly connected to the surface of the turntable, and an exhaust hole is provided at the top of the turntable. When the stirring motor is turned on, the output end of the stirring motor drives the main gear to rotate, the main gear drives the driven gear to rotate, the driven gear drives the stirring rod to rotate, and the stirring rod drives the turntable and impeller to rotate. At the same time, gas is introduced into the inner cavity of the stirring rod. The gas enters the inner cavity of the turntable from the stirring rod and finally exits from the exhaust hole at the top of the turntable to generate bubbles. The upward force of the bubbles can drive the coarse sand at the bottom of the inner cavity of the stirring drum to move upward and mix with the upper slurry, thereby avoiding the stratification of coarse and fine slurries during the mineral processing operation.

[0007] The present invention is further configured such that a limiting shell is fixedly connected to the top and bottom of the movable disc, a limiting disk is movably connected to the inner cavity of the limiting shell, and the inner cavity of the limiting disk is fixedly connected to the surface of the stirring rod. The limiting disk rotates in the inner cavity of the limiting shell as the stirring rod rotates. The limiting shell and the limiting disk form a limiting structure at the top and bottom of the movable disc, thereby limiting the stirring rod and preventing it from moving relative to the movable disc.

[0008] The present invention is further configured such that a limiting plate is fixedly connected to one side of the movable disk, a limiting rod is connected through the surface of the limiting plate, the bottom of the limiting rod is fixedly connected to the top of the top cover, the limiting plate moves with the movable disk on the surface of the limiting rod, and the inner diameter of the limiting hole on the surface of the limiting plate is adapted to the diameter of the limiting rod. The limiting structure composed of the limiting plate and the limiting rod can improve the stability of the movable disk when it moves up and down and prevent shaking.

[0009] The present invention is further configured such that a discharge port is provided at the bottom of one side of the mixing drum, and a sealing plug is provided in the inner cavity of the discharge port. After the material in the inner cavity of the mixing drum is mixed, the sealing plug in the inner cavity of the discharge port is removed, and the mixed material will flow out through the discharge port.

[0010] The present invention is further configured such that a limiting seat is fixedly connected to the top of the top cover, and a card seat is movably connected to the inner cavity of the limiting seat. The top of the card seat is fixedly connected to the bottom of the movable plate. The soft card seat contacts the inner cavity of the limiting seat after the movable plate moves down to its limit distance. The limiting structure composed of the limiting seat and the card seat can prevent the bottom of the movable plate from directly contacting the top of the top cover.

[0011] The present invention is further configured such that a gas inlet is provided at the top of the stirring rod, and a sealing ring is fixedly connected to the top of the gas inlet. One end of an external gas supply pipe is inserted into the inner cavity of the gas inlet, and the sealing ring at the top of the gas inlet covers the surface of the gas supply pipe, thereby enabling the external gas supply pipe to communicate with the inner cavity of the stirring rod, facilitating the subsequent injection of gas into the inner cavity of the stirring rod.

[0012] The present invention is further configured such that support pads are fixedly connected to both sides of the bottom of the base, and anti-slip particles are provided on the bottom of the support pads. The anti-slip particles can improve the friction of the bottom of the support pads. The support pads with high bottom friction can improve the anti-slip properties of the bottom of the base, so that the base can stably support the bottom of the mixing cylinder.

[0013] The present invention has the following beneficial effects.

[0014] 1. After the drive motor is turned on, the output shaft of the drive motor drives the cam to rotate. The long end and short end of the cam alternately contact the bottom of the extension plate, causing the extension plate to drive the connecting plate, drive sleeve, movable disc, stirring rod and impeller to move up and down reciprocally. This up and down reciprocating stirring method breaks the traditional stirring method that relies solely on the rotation of components. It allows the stirring rod and impeller to contact the material more comprehensively in the inner cavity of the stirring drum, fully stirring the slurry in different areas and greatly improving the stirring efficiency of the material.

[0015] 2. In the stirring process of this utility model, the gas introduced into the inner cavity of the stirring rod is eventually discharged from the exhaust hole at the top of the turntable to generate bubbles. The upward floating force of the bubbles can drive the coarse sand at the bottom of the inner cavity of the stirring drum to move upward and mix with the upper slurry. Compared with the traditional method, which can only affect the fine slurry in a local area at the bottom of the stirring drum and the bubbles will disperse as they rise, its bubble action is more precise and can promote the overall mixing of coarse and fine slurries, effectively avoiding the stratification of coarse and fine slurries in mineral processing, thereby reducing the impact of stratification on the mixing effect of slurry and reagents.

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1 Please see Figure 1-5This utility model is a stirring device for gold ore beneficiation, including a base 1, a stirring cylinder 2 fixedly connected to the top of the base 1, a top cover 3 provided on the top of the stirring cylinder 2, a stirring assembly 4 provided on the top of the stirring cylinder 2, a vertical frame 5 fixedly connected to one side of the top of the base 1, a driving assembly 6 provided on the top of the surface of the vertical frame 5, the driving assembly 6 including a movable sleeve 601, the inner wall of the movable sleeve 601 contacting the surface of the vertical frame 5, and a fixing plate 602 fixedly connected to the top of one side of the vertical frame 5. A drive motor 603 is fixedly connected to the back, and a cam 604 is fixedly connected to the output shaft of the drive motor 603. An extension plate 605 is fixedly connected to one side of the movable sleeve 601. A connecting plate 606 is fixedly connected to the side of the movable sleeve 601 away from the extension plate 605. A drive sleeve 607 is fixedly connected to one side of the connecting plate 606. Springs 608 are fixedly connected to both sides of the top of the connecting plate 606. A top plate 609 is fixedly connected to the top of the springs 608. One side of the top plate 609 is fixedly connected to the surface of the vertical frame 5.

[0025] Specifically: When the drive motor 603 is turned on, the output shaft of the drive motor 603 drives the cam 604 to rotate. As the cam 604 rotates, its long end and short end reciprocate in contact with the bottom of the extension plate 605. When the long end contacts the extension plate 605, it will lift the extension plate 605. The extension plate 605 drives the connecting plate 606 and the drive sleeve 607 to move upward. The drive sleeve 607 drives the stirring component 4 on one side to move upward. When the cam 604 rotates to the point where its short end contacts the extension plate 605, the extension plate 605 will move downward, and the stirring component 4 will move downward accordingly. As the cam 604 rotates continuously, the stirring component 4 will move up and down reciprocally, thereby improving the stirring efficiency of the stirring component 4. The drive motor 603 is a Y2 series three-phase asynchronous motor, specifically model Y2-132M-4, with a rated power of 7.5kW and a rated torque of 49.4N·m, to meet the power and torque requirements for driving the cam 604 and driving the stirring component 4 to move up and down reciprocally.

[0026] Example 2 Please see Figure 1-5Based on Embodiment 1, the stirring assembly 4 includes a fixed frame 401. The surface of the fixed frame 401 is fixedly connected to one side of the connecting plate 606. A movable disk 402 is fixedly connected to the bottom of the fixed frame 401. A stirring motor 403 is fixedly connected to one side of the top of the movable disk 402. A main gear 404 is fixedly connected to the output shaft of the stirring motor 403. A stirring rod 405 is passed through the surface of the top cover 3. A driven gear 406 is fixedly connected to the top of the surface of the stirring rod 405. A turntable 407 is fixedly connected to the bottom of the stirring rod 405. An impeller 408 is fixedly connected to the surface of the turntable 407. An exhaust hole 409 is opened at the top of the turntable 407. A fixed plate is fixedly connected to both the top and bottom of the movable disk 402. The inner cavity of the housing 7 is movably connected to the limiting plate 8. The inner cavity of the limiting plate 8 is fixedly connected to the surface of the stirring rod 405. A limiting plate is fixedly connected to one side of the movable plate 402. A limiting rod is connected through the surface of the limiting plate. The bottom of the limiting rod is fixedly connected to the top of the top cover 3. A discharge port is provided at the bottom of one side of the stirring cylinder 2. A sealing plug is provided in the inner cavity of the discharge port. A limiting seat is fixedly connected to the top of the top cover 3. A retaining seat is movably connected to the inner cavity of the limiting seat. The top of the retaining seat is fixedly connected to the bottom of the movable plate 402. An air inlet is provided at the top of the stirring rod 405. A sealing ring is fixedly connected to the top of the air inlet. Support pads are fixedly connected to both sides of the bottom of the base 1. Anti-slip particles are provided at the bottom of the support pads.

[0027] Specifically: The stirring motor 403 is turned on. The output of the stirring motor 403 drives the main gear 404 to rotate, which in turn drives the driven gear 406 to rotate. The driven gear 406 then drives the stirring rod 405 to rotate, which in turn drives the turntable 407 and impeller 408 to rotate. Simultaneously, gas is introduced into the inner cavity of the stirring rod 405. The gas enters the inner cavity of the turntable 407 from the stirring rod 405 and eventually exits through the vent hole 409 at the top of the turntable 407, generating bubbles. The upward force of these bubbles can drive the coarse sand at the bottom of the mixing drum 2 to move upward and mix with the upper slurry, thus avoiding the formation of bubbles. During mining operations, coarse and fine slurries are separated. The limiting disc 8 rotates within the limiting shell 7 as the stirring rod 405 rotates. The limiting shell 7 and the limiting disc 8 form a limiting structure at the top and bottom of the movable disc 402, limiting the stirring rod 405 and preventing it from moving relative to the movable disc 402. The limiting plate moves with the movable disc 402 on the surface of the limiting rod. The inner diameter of the limiting hole on the surface of the limiting plate matches the diameter of the limiting rod. This limiting structure, consisting of the limiting plate and the limiting rod, improves the stability of the movable disc 402 during vertical movement, preventing wobbling. When the stirring drum 2... After the materials in the cavity are mixed, remove the sealing plug from the inner cavity of the discharge port. The mixed materials will then flow out through the discharge port. The soft-material retainer moves down to its limit distance with the movable plate 402 and contacts the inner cavity of the limiting seat. The limiting structure formed by the limiting seat and the retainer prevents the bottom of the movable plate 402 from directly contacting the top of the top cover 3. Insert one end of the external air supply pipe into the inner cavity of the air inlet. The sealing ring at the top of the air inlet covers the surface of the air supply pipe, thereby connecting the external air supply pipe with the inner cavity of the stirring rod 405, facilitating subsequent injection into the inner cavity of the stirring rod 405. The introduction of gas and anti-slip particles can increase the friction of the bottom of the support pad. The support pad with high bottom friction can improve the anti-slip performance of the bottom of the base 1, so that the base 1 can stably support the bottom of the mixing drum 2. The stirring motor 403 is a YE3 series high-efficiency three-phase asynchronous motor, specifically model YE3-112M-4, with a rated power of 4.0kW and a rated torque of 26.5N·m. This model of motor has high starting torque and overload capacity, which can ensure stable driving of the stirring rod 405, turntable 407 and impeller 408 to rotate under the transmission of the main gear 404 and the driven gear 406.

[0028] The working principle of this utility model is as follows: First, the stirring device is connected to the power supply, and the stirring motor 403 is turned on. The output end of the stirring motor 403 drives the main gear 404 to rotate, the main gear 404 drives the driven gear 406 to rotate, the driven gear 406 drives the stirring rod 405 to rotate, and the stirring rod 405 drives the turntable 407 and impeller 408 to rotate. At the same time, gas is introduced into the inner cavity of the stirring rod 405. The gas enters the inner cavity of the turntable 407 from the stirring rod 405 and finally exits from the exhaust hole 409 at the top of the turntable 407, generating bubbles. The upward force of the bubbles can drive the coarse sand at the bottom of the inner cavity of the stirring drum 2 to move upward and mix with the upper slurry, thereby avoiding the stratification of coarse and fine slurry during the mineral processing operation. At the same time, the drive motor 603 is turned on. The output shaft drives the cam 604 to rotate. As the cam 604 rotates, its long and short ends reciprocate to the bottom of the extension plate 605. When the long end contacts the extension plate 605, it lifts the extension plate 605. The extension plate 605 drives the connecting plate 606 and the drive sleeve 607 to move upward. The drive sleeve 607 drives the movable disk 402 on one side to move upward. The movable disk 402 drives the stirring rod 405 and its impeller 408 to move upward in the inner cavity of the mixing drum 2. When the cam 604 rotates to the point where its short end contacts the extension plate 605, the extension plate 605 moves downward. The stirring rod 405 and the impeller 408 move downward accordingly. As the cam 604 rotates continuously, the stirring rod 405 and the impeller 408 move up and down reciprocally, thereby improving the stirring efficiency of the material.
