Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a slurry sedimentation and classification 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 actual production, the slurry needs to be sedimented and classified so that the mineral particles in the slurry can be collected and utilized.

[0003] After searching, the Chinese patent publication number CN110898980A discloses a slurry sedimentation and classification equipment, which mainly installs an inclination angle adjustment device at the lower end of the classification box to tilt the classification box. By adjusting the inclination angle, the slurry flow speed is adjusted, and then the classification time is determined, so that the classification effect of the slurry is better.

[0004] By comparing with the existing technologies in related fields, it can be seen that when the existing sedimentation and classification equipment is fed, the slurry mostly enters the sedimentation and classification equipment directly through the pipeline. The impact force when the slurry is discharged will affect the sedimentation of the slurry, and the existing sedimentation and classification equipment mostly uses the weight of the slurry particles in the slurry for sedimentation. The efficiency of sedimentation and classification is low, which slows down the speed of slurry processing. Utility Model Content

[0005] The purpose of the utility model is to provide a slurry sedimentation and classification device in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A slurry sedimentation and classification device, comprising a sedimentation cylinder and a classification unit:

[0008] The classification unit is arranged inside the settling cylinder. The slurry is settled in the settling cylinder. The mineral particles in the slurry are classified by the classification unit, so that different mineral particles can be collected separately, so that the mineral particles in the slurry can be better recycled.

[0009] The grading unit includes a first discharge pipe, a feed pipe, a drug feed pipe, and a second discharge pipe. The first discharge pipe is arranged in the sedimentation cylinder. The feed pipe and the drug feed pipe are both arranged on the sedimentation cylinder. A material distribution seat is arranged on the portion of the feed pipe located in the first discharge pipe, and a nozzle is arranged on the material distribution seat at an equal angle. A drug distribution ring is arranged on the portion of the drug feed pipe located in the sedimentation cylinder, and a drug outlet is arranged on the drug distribution ring at an equal angle. The drug outlet is at the same height as the upper end of the first discharge pipe. The second discharge pipe is rotatably installed on the lower surface of the sedimentation cylinder. A filter is arranged on the portion of the second discharge pipe located in the sedimentation cylinder. The material pipe and the filter are sleeved on the first discharge pipe, the lower surface of the sedimentation cylinder is provided with a driving component and a third discharge pipe, the lower ends of the first discharge pipe, the second discharge pipe and the third discharge pipe are all provided with valves, the third discharge pipe is located between the filter screen and the sedimentation cylinder, the feed pipe is connected to an external slurry conveying device, the drug feed pipe is connected to an external drug delivery device, the driving component is connected to the second discharge pipe, the first discharge pipe, the second discharge pipe and the third discharge pipe are controlled by the valve to control the on and off of the first discharge pipe, the second discharge pipe and the third discharge pipe, so as to control the amount of the first discharge pipe, the second discharge pipe and the third discharge pipe, the external slurry conveying device conveys the slurry into the first discharge pipe through the feed pipe, the material distribution seat and the nozzle, and the slurry is transported to the first discharge pipe through the tilting The obliquely arranged nozzle allows the slurry to be evenly dispersed in the first discharge pipe, which is convenient for the large-particle mineral particles in the slurry to settle, and can reduce the obstruction of the entering slurry to the settling mineral particles. The large-particle mineral particles settle in the first discharge pipe and are discharged through the first discharge pipe. The small-particle mineral particles in the slurry enter the sedimentation cylinder through the upper end of the first discharge pipe. At the same time, the external drug delivery device delivers the flocculation agent into the sedimentation cylinder through the drug inlet pipe, the drug distribution ring and the drug outlet. The slurry overflowing from the first discharge pipe drives the flocculation agent to move, so that the slurry and the flocculation agent are fully mixed, and the mineral particles flocculated in the slurry and the slurry enter the filter. The mineral particles settle along the filter and are discharged through the second discharge pipe. The settled slurry is filtered through the filter and then enters the third discharge pipe for discharge. At the same time, the driving component drives the filter to rotate through the second discharge pipe. The rotation of the filter prevents the flocculated mineral particles from accumulating on the filter, so that the flocculated mineral particles can settle better in the filter. Different settled mineral particles and slurry are discharged through the first discharge pipe, the second discharge pipe, and the third discharge pipe, thereby realizing rapid sedimentation and classification of the slurry, effectively improving the efficiency and accuracy of slurry sedimentation and classification, reducing the content of mineral particles after the slurry is settled, and facilitating the recycling of water in the slurry.

[0010] Furthermore, the driving assembly includes a driven gear, a driving gear, and a motor. The driven gear is arranged on the part of the second discharge pipe below the sedimentation cylinder. The motor is arranged on the sedimentation cylinder. The driving gear is arranged on the output shaft of the motor. The driving gear is meshed and connected with the driven gear. The input end of the motor is electrically connected to the output end of an external controller. The external controller controls the operation of the motor using existing technology. The motor drives the second discharge pipe to rotate through the driving gear and the driven gear.

[0011] Furthermore, the grading unit also includes a fixed rod and a top plate. The fixed rod is arranged at an equal angle in the sedimentation cylinder. The top plate is arranged on the fixed rod. The top plate is slidably connected to the filter. When the filter rotates, the filter is pushed by the fixed rod and the top plate, so that the contact position between the filter and the top plate is deformed. After the filter moves past the position of the top plate, the thrust of the top plate on the filter disappears, and the deformed part of the filter is reset under the action of its own elastic force, thereby shaking off the mineral particles on the filter to avoid clogging the filter by the mineral particles and ensuring the normal filtering effect of the filter.

[0012] Furthermore, the grading unit also includes a support rod and a stirring rod. The support rod is arranged at an equal angle on the upper end of the filter. The stirring rod is arranged on the upper end of the support rod. Both ends of the stirring rod are respectively slidably connected to the sedimentation cylinder and the first discharge pipe. The first discharge pipe is supported by the stirring rod. At the same time, the filter drives the stirring rod to rotate through the support rod, and the mortar in the sedimentation cylinder is stirred by the support rod and the stirring rod, so that the mortar and the flocculation agent are fully mixed, so that the particles in the mortar can be better settled.

[0013] Furthermore, it also includes a limit seat, which is arranged in the sedimentation cylinder and is slidably connected to the upper end of the filter. When the filter rotates, the filter is guided and limited by the limit seat to maintain the stability of the upper end of the filter when it rotates.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The inclined nozzle makes the slurry evenly dispersed in the first discharge pipe, which is convenient for the large-particle mineral particles in the slurry to settle, and can reduce the obstruction of the incoming slurry to the settling mineral particles, ensuring the settling speed of the mineral particles. The slurry is initially settled in the first discharge pipe, and the flocculation agent is introduced into the sedimentation cylinder through the medicine inlet pipe, the medicine dividing ring, and the medicine outlet, so that the small-particle mineral particles in the slurry are flocculated into agglomerates, thereby facilitating the sedimentation of the mineral particles. The slurry is filtered through the filter screen, and the flocculated mineral particles are discharged through the second discharge pipe. The slurry after sedimentation and filtration is discharged through the third discharge pipe, thereby realizing the rapid sedimentation and classification of the slurry, effectively improving the efficiency and accuracy of the slurry sedimentation classification, and reducing the content of mineral particles in the slurry after the slurry is settled.

[0016] 2. During the sedimentation and classification of the slurry, the upper end of the first discharge pipe and the discharge port are set at the same height, so that the slurry overflowing from the first discharge pipe drives the flocculation agent to move, and then the slurry and the flocculation agent are stirred by the support rod and the stirring rod, so that the mortar and the flocculation agent are fully mixed, and the weight of the flocculated mineral particles is increased, so that the mineral particles in the slurry can be better settled; at the same time, the rotating filter can prevent the flocculated mineral particles from accumulating on the filter. When the filter rotates, the filter is deformed by the fixed rod and the top plate, so that the mineral particles on the filter are shaken off, avoiding the clogging of the filter by the mineral particles, ensuring the normal filtering effect of the filter, and avoiding affecting the sedimentation and classification of the slurry.

[0030] Example

[0031] like Figure 1-Figure 7 As shown, a slurry sedimentation and classification device includes a sedimentation cylinder 1 and a classification unit 2:

[0032] The sedimentation cylinder 1 is provided with a classification unit 2 inside, and the slurry is settled in the sedimentation cylinder 1. Figure 1 , Figure 3 As shown, the mineral particles in the ore pulp are classified by the classification unit 2, so that different mineral particles can be collected separately, so that the mineral particles in the ore pulp can be better recycled;

[0033] The grading unit 2 includes a first discharge pipe 21, a feed pipe 22, a drug feed pipe 25, and a second discharge pipe 29. The first discharge pipe 21 is arranged in the sedimentation cylinder 1, and the feed pipe 22 and the drug feed pipe 25 are both arranged on the sedimentation cylinder 1. A material distribution seat 23 is arranged on the portion of the feed pipe 22 located in the first discharge pipe 21, and a nozzle 24 is arranged at an equal angle on the material distribution seat 23. A drug distribution ring 26 is arranged on the portion of the drug feed pipe 25 located in the sedimentation cylinder 1, and a drug outlet 27 is arranged at an equal angle on the drug distribution ring 26.

Figure 1-Figure 7As shown, the external slurry conveying device conveys the slurry into the distribution seat 23 through the feed pipe 22, and then conveys the slurry into the first discharge pipe 21 through the nozzle 24. The slurry is evenly dispersed in the first discharge pipe 21 through the inclined nozzle 24, which is convenient for the large-grained mineral particles in the slurry to settle, and can reduce the obstruction of the entering slurry to the settled mineral particles. The large-grained mineral particles settle in the first discharge pipe 21 and are discharged through the first discharge pipe 21. The small-grained mineral particles in the slurry enter the sedimentation tube 1 through the upper end of the first discharge pipe 21. At the same time, the external drug delivery device conveys the flocculation agent into the drug distribution ring 26 through the drug feed pipe 25, and then conveys the flocculation agent into the sedimentation tube 1 through the drug outlet 27. Since the upper end of the first discharge pipe 21 and the drug outlet 27 are at the same height, the slurry overflowing from the first discharge pipe 21 drives the flocculation agent to move. Thereby, the ore pulp and the flocculating agent are fully mixed, and the mineral particles flocculated in the ore pulp and the ore pulp enter the filter 28, and the mineral particles flocculated in the ore pulp settle along the filter 28 and are discharged through the second discharge pipe 29. The settled ore pulp is filtered through the filter 28 and enters the third discharge pipe 217 for discharge.

The driven gear 210 is arranged on the portion of the second discharge pipe 29 located below the sedimentation cylinder 1. The motor 212 is arranged on the sedimentation cylinder 1. The driving gear 211 is arranged on the output shaft of the motor 212. The driving gear 211 is meshed and connected with the driven gear 210. Figure 2 , Figure 3 As shown, the input end of the motor 212 is electrically connected to the output end of the external controller. The external controller controls the operation of the motor 212 using existing technology. The motor 212 drives the driving gear 211 to rotate, the driving gear 211 drives the driven gear 210 to rotate, and the driven gear 210 drives the second discharge pipe 29 to rotate.

[0035] The classification unit 2 further includes a fixed rod 213 and a top plate 214. The fixed rod 213 is arranged at an equal angle in the sedimentation cylinder 1. The top plate 214 is arranged on the fixed rod 213. The top plate 214 is slidably connected to the filter screen 28. Figure 3 , Figure 5 , Figure 6As shown, when the filter screen 28 rotates, the filter screen 28 is pushed by the fixing rod 213 and the top plate 214, so that the position where the filter screen 28 contacts the top plate 214 is deformed. After the filter screen 28 moves past the position of the top plate 214, the thrust of the top plate 214 on the filter screen 28 disappears, and the deformed part of the filter screen 28 is reset under the action of its own elastic force, thereby shaking off the mineral particles on the filter screen 28, avoiding clogging of the filter screen 28 by the mineral particles, and ensuring the normal filtering effect of the filter screen 28.

[0036] The classification unit 2 further includes a support rod 215 and a stirring rod 216. The support rod 215 is arranged at an equal angle on the upper end of the filter screen 28. The upper end of the support rod 215 is provided with a stirring rod 216. The two ends of the stirring rod 216 are respectively slidably connected to the sedimentation cylinder 1 and the first discharge pipe 21. Figure 3 , Figure 5 , Figure 6 As shown, the first discharge pipe 21 is supported by the stirring rod 216 to improve the stability of the first discharge pipe 21. At the same time, the filter screen 28 drives the stirring rod 216 to rotate through the support rod 215, and the mortar in the sedimentation cylinder 1 is stirred by the support rod 215 and the stirring rod 216, so that the mortar and the flocculation agent are fully mixed, so that the particles in the mortar can be better settled.

[0037] The filter 28 also includes a limit seat 4, which is arranged in the sedimentation cylinder 1 and is slidably connected to the upper end of the filter screen 28. Figure 3 , Figure 6 As shown, when the filter screen 28 rotates, the filter screen 28 is guided and limited by the limit seat 4, and the stability of the upper end of the filter screen 28 during rotation is maintained by the limit seat 4.

[0038] Working principle: Figure 1 , Figure 3 , Figure 6 , Figure 7 As shown, the external slurry conveying device conveys the slurry into the material distribution seat 23 through the feed pipe 22, and then conveys the slurry into the first discharge pipe 21 through the nozzle 24.

Since the first discharge pipe 21 and the drug outlet 27 are at the same height, the slurry overflowing from the first discharge pipe 21 drives the flocculating agent to move, so that the slurry and the flocculating agent are fully mixed; the flocculated mineral particles in the slurry settle along the filter screen 28 and are discharged through the second discharge pipe 29. The settled slurry is filtered through the filter screen 28 and enters the third discharge pipe 217 for discharge;

[0040] At the same time, if Figure 2 , Figure 3 As shown, the motor 212 drives the driving gear 211 to rotate, the driving gear 211 drives the driven gear 210 to rotate, the driven gear 210 drives the second discharge pipe 29 to rotate, and the second discharge pipe 29 drives the filter screen 28 to rotate.

Figure 3 , Figure 6 As shown, when the filter screen 28 rotates, the filter screen 28 is guided and limited by the limiting seat 4 to improve the stability of the filter screen 28; at the same time, as shown in FIG. Figure 3 , Figure 5 , Figure 6 As shown, while the filter screen 28 rotates, the stirring rod 216 is driven to rotate through the support rod 215, and the mortar in the sedimentation cylinder 1 is stirred by the support rod 215 and the stirring rod 216, so that the mortar and the flocculation agent are fully mixed, and the first discharge pipe 21 is supported by the stirring rod 216 to improve the stability of the first discharge pipe 21;

[0041] When the filter screen 28 rotates, Figure 3 , Figure 5 , Figure 6 As shown, the fixing rod 213 pushes the filter 28 through the top plate 214, so that the position where the filter 28 contacts the top plate 214 is deformed. After the filter 28 moves past the position of the top plate 214, the thrust of the top plate 214 on the filter 28 disappears, and the deformed part on the filter 28 is reset under the action of its own elastic force, thereby shaking off the mineral particles on the filter 28, avoiding clogging of the filter 28 by the mineral particles, and ensuring the normal filtering effect of the filter 28.
