A slurry preparation device for the pretreatment of a slurry of a mineral

Abstract

This utility model relates to the field of pretreatment flotation slurry preparation technology, and discloses a pretreatment flotation slurry preparation device for muddy minerals. This utility model solves the problem that mineral raw materials usually contain large particles of powder, and when directly added to a mixing tank for stirring, the large mineral particles result in a small contact area with the reagents, leading to uneven mixing of the minerals and reagents. This utility model uses a screening component including a threaded rod II, a motor II mounted through the top cover, and a grinding block threaded through the threaded rod II. Limit rods slide through both ends of the grinding block, and a screening frame is set on the lower side of the grinding block. When the motor I is started, the threaded rod I rotates, causing the screening frame to rotate. Smaller materials, under the action of centrifugal force, pass through the perimeter of the screening frame and fall to the bottom of the treatment tank. When the motor II is started, the threaded rod II rotates, causing the grinding block to move downwards. The grinding block grinds the large particles of material into small particles of powder, resulting in a larger contact area between the small particles and the reagents, and a more uniform mixing of the material and the reagents.

Description

Technical Field

[0001] This utility model relates to the field of pretreatment flotation slurry preparation technology, specifically to a muddy ore pretreatment flotation slurry preparation device. Background Technology

[0002] In the field of mineral resource processing, the treatment of mud-like ore is a major challenge. Due to its fine particle size and easy mudification, mud-like ore faces many challenges in pre-flotation pulp preparation. Currently, commonly used flotation pulp preparation equipment is mostly designed for conventional ores and has significant shortcomings when used for mud-like ore. For example, it cannot effectively disperse mud-like ore particles, easily causing agglomeration and affecting subsequent flotation results; it cannot accurately control the pulp concentration and reagent dosage, making it difficult to adapt to the complex and variable properties of mud-like ore; and the stirring intensity and method of the equipment lack specificity, making it difficult to ensure that the reagents and mud-like ore are fully and evenly mixed. These problems result in low flotation recovery rates and serious resource waste of mud-like ore. Therefore, there is an urgent need for a flotation pulp preparation device specifically designed for the pretreatment of mud-like ore to improve flotation efficiency and resource utilization.

[0003] A Chinese patent with publication number CN219540608U discloses a cyclone tailings flotation device, including a flotation box and a mixing box. The tailings are added to the mixing box through the feeding funnel, and the reagents are added to the mixing box through the liquid inlet. The servo motor is started, and the output of the servo motor drives the rotating rod to rotate. The rotating rod drives the mixing rod to rotate, and the mixing rod can stir the tailings and reagents, so that the tailings and reagents are fully mixed to form a slurry.

[0004] The problem with the aforementioned technologies is that mineral raw materials usually contain large powder particles. When these particles are directly added to a mixing tank for stirring, the large size of the mineral particles results in a small contact area with the drug, leading to uneven mixing of the minerals and the drug. Utility Model Content

[0005] The purpose of this invention is to provide a flotation slurry preparation device for pretreatment of muddy minerals. By using this device, the problem of uneven mixing of minerals and reagents is solved, which is caused by the large particle size of mineral raw materials, which are usually powdery and are directly put into the mixing tank for stirring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flotation slurry preparation device for pretreatment of muddy ore, comprising a treatment tank, a top cover installed at the upper end of the treatment tank, three feed holes opened on the top cover, a motor installed through the bottom of the treatment tank, a threaded rod rotatably installed on the treatment tank, the drive end of the motor fixedly connected to the threaded rod, a screening assembly provided at the upper end of the threaded rod, the screening assembly including a second threaded rod, the upper end of the second threaded rod rotatably connected to the top cover, a second motor installed through the top cover, the drive end of the second motor fixedly connected to the second threaded rod, a grinding block threaded through the second threaded rod, limit rods slidingly passing through both ends of the grinding block, the upper ends of the two limit rods fixedly connected to the top cover, a screening frame provided on the lower side of the grinding block, the lower end of the screening frame fixedly connected to the first threaded rod.

[0007] Material is fed into the processing tank through the feed hole and falls onto the screening frame. Motor 1 is started, and its drive end rotates the threaded rod, which in turn rotates the screening frame. Smaller particles pass through the perimeter of the screening frame under centrifugal force and fall to the bottom of the processing tank. Then, Motor 2 is started, and its drive end rotates the threaded rod, which moves the grinding block downwards along the limit rod. The grinding block grinds the large particles at the bottom of the screening frame into small powder particles. These small powder particles can enter the bottom of the processing tank through the gaps around the screening frame, thereby increasing the contact area between the material and the reagent and making the mixture more uniform.

[0008] Preferably, the upper end of the screening frame is funnel-shaped, and the upper end of the screening frame is in close contact with the inner wall of the processing tank.

[0009] Material fed into the processing tank through the feed port can fall from the top of the screening frame to the bottom.

[0010] Preferably, a guide ring one is installed at the upper end of the top cover, and a guide ring two is provided in the middle of the guide ring one. The guide ring two is installed at the upper end of the top cover, and the feed hole is located between the guide ring one and the guide ring two.

[0011] The material enters the feed hole along guide ring one and guide ring two, and then falls into the processing tank.

[0012] Preferably, a guide channel is provided on the inner wall of the processing tank, and the guide channel is located around the screening frame.

[0013] Small particles that pass through the gaps in the screening frame due to centrifugal force fall onto the guide trough and then fall along the guide trough to the bottom of the processing tank.

[0014] Preferably, a mixing component is installed on the threaded rod, the mixing component includes an extrusion block, the diameter of which is smaller than the diameter of the inner wall of the processing tank, the extrusion block is threaded onto the threaded rod, limit blocks are installed at both ends of the extrusion block, limit grooves are formed on both sides of the inner wall of the processing tank, the limit blocks and limit grooves are slidably connected, and rotating rings are rotatably installed at both ends of the extrusion block, both rotating rings are threaded to the threaded rod, and stirring blades are installed on both sides of the two rotating rings.

[0015] After the drive end of motor one drives the threaded rod one to rotate, the extrusion block moves downward and squeezes the slurry downward, so that the slurry passes through the gap between the extrusion block and the inner wall of the treatment tank. At the same time, the two rotating rings rotate along the threaded rod one, so that the stirring plate rotates. The extrusion block and the stirring plate work together to agitate the slurry, so that the slurry flows in the treatment tank, increasing the number of times the minerals and reagents come into contact, thereby making the minerals and reagents mix more evenly.

[0016] Preferably, the upper and lower parts of the extrusion block are arranged in a symmetrical conical shape.

[0017] As the extrusion block moves downwards, the slurry flows upwards along the perimeter of the lower part of the extrusion block, thus creating a flow in the slurry.

[0018] Preferably, a fixing ring is installed on the outside of the processing tank, four fixing blocks are installed on the outside of the fixing ring, and a fixing post is installed at the lower end of the fixing blocks.

[0019] The four fixed columns provide support for the treatment tank.

[0020] Preferably, the treatment tank is equipped with a reagent tube and a discharge tube, with the reagent tube located on the upper side of the fixing ring and the discharge tube located on the lower side of the fixing ring.

[0021] The reagents are added to the processing tank through the reagent tube, and the mixed slurry is collected through the discharge pipe.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model proposes a flotation slurry preparation device for pretreatment of muddy ore. The material is fed into the treatment tank through the feed hole and falls onto the screening frame. Motor 1 is started, and its drive end rotates the threaded rod, which in turn rotates the screening frame. Smaller particles, under centrifugal force, pass through the perimeter of the screening frame and fall to the bottom of the treatment tank. Then, Motor 2 is started, and its drive end rotates the threaded rod, which moves the grinding block downwards along the limiting rod. The grinding block grinds the large particles at the bottom of the screening frame into smaller powder particles. These smaller powder particles can enter the bottom of the treatment tank through the gaps around the screening frame, thereby increasing the contact area between the material and the reagent, resulting in a more uniform mixture.

[0033] Combination Figures 1-4A flotation slurry preparation device for pretreatment of muddy ore includes a treatment tank 1, a top cover 2 installed on the upper end of the treatment tank 1, three feed holes 21 on the top cover 2, a motor 3 installed through the bottom of the treatment tank 1, a threaded rod 4 rotatably installed on the treatment tank 1, the drive end of the motor 3 being fixedly connected to the threaded rod 4, a screening assembly 5 provided at the upper end of the threaded rod 4, the screening assembly 5 including a second threaded rod 51, the upper end of the second threaded rod 51 being rotatably connected to the top cover 2. A motor 52 is mounted through the top cover 2. The drive end of the motor 52 is fixedly connected to a threaded rod 51. A grinding block 53 is threaded through the threaded rod 51. Limiting rods 54 slide through both ends of the grinding block 53. The upper ends of the two limiting rods 54 are fixedly connected to the top cover 2. A screening frame 55 is provided on the lower side of the grinding block 53. The upper end of the screening frame 55 is funnel-shaped and fits tightly against the inner wall of the processing tank 1. Material fed into the processing tank 1 through hole 21 can fall from the top of the screening frame 55 to the bottom. The bottom of the screening frame 55 is fixedly connected to the threaded rod 4. When the material is fed into the processing tank 1 through the feed hole 21 and falls onto the screening frame 55, the motor 3 is started. The drive end of the motor 3 drives the threaded rod 4 to rotate, thereby rotating the screening frame 55. Smaller particles pass through the periphery of the screening frame 55 under the action of centrifugal force and fall to the bottom of the processing tank 1. Then, the motor 2 is started. The drive end of the motor 2 is driven by the threaded rod 2 to rotate, thereby moving the grinding block 53 downward along the limit rod 54. The grinding block 53 grinds the large particles that fall to the bottom of the screening frame 55 into small powder particles. The small powder particles can enter the bottom of the processing tank 1 through the gaps around the screening frame 55, thereby increasing the contact area between the material and the agent and making the material and agent mix more evenly.

[0034] Combination Figures 2-3 A guide ring 22 is installed on the upper end of the top cover 2. A guide ring 23 is set in the middle of the guide ring 22. The guide ring 23 is installed on the upper end of the top cover 2. The feed hole 21 is located between the guide ring 22 and the guide ring 23. The material enters the feed hole 21 along the guide ring 22 and the guide ring 23, and then falls into the processing tank 1. A guide channel 11 is opened on the inner wall of the processing tank 1. The guide channel 11 is located around the screening frame 55. Small particles of material that pass through the gaps in the screening frame 55 due to centripetal force fall onto the guide channel 11 and then fall to the bottom of the processing tank 1 along the guide channel 11.

[0035] Combination Figures 2-3 , Figures 5-6A mixing component 6 is installed on the threaded rod 4. The mixing component 6 includes an extrusion block 61. The diameter of the extrusion block 61 is smaller than the diameter of the inner wall of the processing tank 1. The extrusion block 61 is threaded onto the threaded rod 4. Limiting blocks 611 are installed at both ends of the extrusion block 61. Limiting grooves 12 are formed on both sides of the inner wall of the processing tank 1. The limiting blocks 611 and the limiting grooves 12 are slidably connected. Rotating rings 62 are rotatably installed at both the upper and lower ends of the extrusion block 61. Both rotating rings 62 are threadedly connected to the threaded rod 4. Stirring blades 621 are installed on both sides of the two rotating rings 62. After the drive end of the motor 3 drives the threaded rod 4 to rotate, the extrusion block 61 moves downward and extrudes the slurry downward, so that the slurry flows along the extrusion block 61 and the inner wall of the processing tank 1. The gap is filled, and at the same time, the two rotating rings 62 rotate along the threaded rod 4, causing the stirring plate 621 to rotate. The extrusion block 61 and the stirring plate 621 work together to agitate the slurry, causing the slurry to flow in the treatment tank 1, increasing the number of times the minerals and reagents come into contact, thus making the minerals and reagents mix more evenly. The upper and lower parts of the extrusion block 61 are symmetrically arranged in a conical shape. When the extrusion block 61 moves downward, the slurry will flow upward along the perimeter of the lower part of the extrusion block 61, thus causing the slurry to flow. When the extrusion block 61 moves to the bottom of the treatment tank 1, the drive end of the motor 3 rotates in the opposite direction, and the extrusion block 61 moves upward, thereby driving the slurry to move downward along the gap between the extrusion block 61 and the inner wall of the treatment tank 1, forming a reverse water flow, which agitates the slurry again.

[0036] Combination Figure 1 A fixing ring 7 is installed on the outside of the treatment tank 1. Four fixing blocks 71 are installed on the outside of the fixing ring 7. Fixing columns 72 are installed at the lower end of the fixing blocks 71. The four fixing columns 72 provide support for the treatment tank 1. A reagent pipe 13 and a discharge pipe 14 are installed on the treatment tank 1. The reagent pipe 13 is located on the upper side of the fixing ring 7, and the discharge pipe 14 is located on the lower side of the fixing ring 7. The reagent is added into the treatment tank 1 through the reagent pipe 13, and the mixed slurry is collected through the discharge pipe 14.

[0037] Working principle: The material is fed into the processing tank 1 through the feed hole 21 and falls onto the screening frame 55. The motor 3 is started, and the drive end of the motor 3 drives the threaded rod 4 to rotate, thereby rotating the screening frame 55. Smaller particles pass through the periphery of the screening frame 55 under the action of centrifugal force and fall to the bottom of the processing tank 1. Then, the motor 52 is started, and the drive end of the motor 52 drives the threaded rod 51 to rotate, thereby moving the grinding block 53 downward along the limit rod 54. The grinding block 53 grinds the large particles that fall to the bottom of the screening frame 55 into small powder particles. The small powder particles can enter the bottom of the processing tank 1 through the gaps around the screening frame 55, thereby increasing the contact area between the material and the agent and making the material and agent mix more evenly.
