Description
Technical Field
[0001] This utility model relates to the field of thickener technology, and in particular to the structure of a thickener used in potash fertilizer production. Background Technology
[0002] Salt lake brines are rich in minerals such as potassium, magnesium, and lithium, and are the main raw materials for the production of potassium chloride, magnesium chloride, and lithium chloride. In the process of producing potassium chloride from brine, a thickener is used to concentrate the crude potassium slurry. The slurry with a solids content of 10%–20% is concentrated by gravity sedimentation into an underflow slurry with a solids content of 45%–55%. Under the agitation of the stirring rake inside the thickener, the underflow slurry is discharged from the underflow outlet at the bottom of the thickener.
[0003] The thickener is the core equipment in the potassium chloride production process. Its stability is highly susceptible to environmental factors and sudden events. Due to the abundance of salt fields and high humidity in the salt lake plant area, magnesium chloride is prone to absorbing moisture and hydrolyzing to form magnesium chloride hexahydrate. Mineral salts containing magnesium chloride are extremely harmful to electrical, electronic, and mechanical components, and can easily cause damage to power distribution equipment, leading to power outages.
[0004] After a power outage, the underflow pump of the thickener stops working and cannot unload the material. The concentration of the material inside the thickener increases rapidly in a short period of time. The sediment, which tends to be compacted, buries the agitator rake of the thickener. After the power is restored, the agitator rake cannot rotate. This phenomenon is called rake compression.
[0005] Current methods for addressing thickening issues typically involve manual flushing with fresh water and increasing the flow rate of the underflow pump to quickly remove sediment from the thickener, allowing it to gradually return to normal operation. However, due to the large size of the thickener (approximately 50m in diameter) and the substantial amount of sediment (around 1m thick), cleaning it requires significant effort and time. A single thickener typically takes over 8 hours to process, severely impacting the continuity of potash fertilizer production and product quality.
[0006] The purpose of this invention is to solve the problem in the existing potassium chloride production process that the cleaning of sediment after thickening and rakeing is difficult, time-consuming, labor-intensive, and affects production. Utility Model Content
[0007] To solve the above problems, this utility model provides a thickener for potash fertilizer production, including a tank body 1, a stirring device 2, a rotating device 3, and a bottom flow pump 16. The tank body 1 is cylindrical with an opening at the top and a bottom plate 12 at the bottom, forming a thickening cavity 11 inside. An overflow trough 13 is provided on the upper part of the inner side wall of the tank body 1, and an overflow port 14 communicating with the overflow trough 13 is provided on the tank body 1. The bottom plate 12 is funnel-shaped, and a discharge port 15 is provided at the tip of the bottom plate 12.
[0008] The stirring device 2 is used to stir the slurry in the thickening chamber 11. The rotating device 3 includes a rotating component 31 and a rotating motor 35. The rotating component 31 is annular and is sleeved on the upper part of the outer side of the tank body 1, and can rotate relative to the tank body 1. A support plate 32 extending towards the middle of the shell is provided on the upper part of the rotating component 31. A high-pressure nozzle 5 is provided on the support plate 32, and the outlet 521 of the high-pressure nozzle 5 faces the bottom of the thickening chamber 11. The rotating motor 35 is fixedly installed on the outer side of the tank body 1 and connected to the rotating component 31, and is used to drive the rotating component 31 to reciprocate. The underflow pump 16 is connected to the discharge port 15.
[0009] In use, crude potassium ore slurry is added to thickening chamber 11 for concentration. The supernatant is discharged from overflow port 14 through overflow tank 13. The concentrated underflow slurry is discharged from discharge port 15 and underflow pump 16 under the stirring action of stirring device 2. After the pressure rake occurs, underflow pump 16 is turned on, and high-pressure nozzle 5 is connected to high-pressure water pipeline. High-pressure water is sprayed into thickening chamber 11 through high-pressure nozzle 5. Rotary motor 35 is turned on, and rotating component 31 is driven to rotate back and forth along tank body 1 through rotating motor 35, which drives high-pressure nozzle 5 to rotate back and forth. High-pressure water is used to evenly wash the sediment on bottom plate 12. High-pressure water causes sediment on bottom plate 12 to turn up quickly. The sediment on bottom plate 12 flows quickly to discharge port 15 and is quickly discharged from discharge port 15 through underflow pump 16. After the sediment is washed, normal production can be resumed.
[0010] This invention utilizes a rotating device 3 to rotatably mount a rotating component 31 onto the outside of the tank body 1. A support plate 32 extending towards the center of the housing is mounted on the rotating component 31, and a high-pressure nozzle 5 is mounted on the support plate 32. A rotating motor 35 is connected to the rotating component 31. After the thickener is rake-down, the high-pressure nozzle 5 is connected to a high-pressure water pipe, allowing high-pressure flushing water to be sprayed into the thickening chamber 11. The rotating motor 35 drives the rotating component 31 to rotate, which in turn drives the high-pressure nozzle 5 to rotate. The high-pressure water evenly flushes the sediment on the bottom plate 12, improving flushing efficiency and coverage. The high-pressure water rapidly stirs up the sediment on the bottom plate 12, collecting it at the discharge port 15 and discharging it via the underflow pump 16. This invention can quickly discharge the sediment from the thickener after rake-down, solving the problems of difficult, time-consuming, and labor-intensive cleaning of sediment after rake-down in existing thickeners, which affects production.

[0033] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0034] like Figure 1 and Figure 3 As shown, a thickener for potash fertilizer production includes a tank 1, a stirring device 2, a rotating device 3, a bottom flow pump 16, and an operating platform 6.
[0035] The pool body 1 is cylindrical with an opening at the top and a bottom plate 12. An internal dense cavity 11 is formed inside. An overflow trough 13 is provided on the upper part of the inner wall of the pool body 1. The overflow trough 13 is annular, surrounding the circumference of the inner wall of the pool body 1, and is open at the top. A serrated overflow weir 131 is provided on the upper part of the side wall of the overflow trough 13 near the center of the dense cavity 11. (Refer to...) Figure 4 .
[0036] The sawtooth overflow weir 131 can block impurities in the slurry, preventing them from entering subsequent production equipment and causing blockages in the conveying pipeline or damage to the equipment.
[0037] The pool body 1 is provided with an overflow port 14 that connects to the overflow trough 13, the bottom plate 12 is funnel-shaped, and the tip of the bottom plate 12 is provided with a discharge port 15.
[0038] The underflow pump 16 is connected to the discharge port 15 and is used to quickly discharge the slurry in the discharge port 15.
[0039] The operating platform 6 has a rectangular structure and is equipped with a protective net. Support legs 61 are provided at both ends and are supported on the bottom surface, thus placing the operating platform 6 above the pool body 1.
[0040] like Figure 1 and Figure 4 As shown, the stirring device 2 includes a stirring motor 21, a stirring rod 22, and a stirring rake 23. The stirring motor 21 is fixedly mounted on the operating platform 6. The stirring rod 22 is vertically arranged, with its upper end fixedly connected to the rotating shaft of the stirring motor 21, and its lower end extending through the operating platform 6 to the bottom of the thickening chamber 11.
[0041] A stirring rake 23 is set inside the thickening chamber 11. One end is fixedly connected to the stirring rod 22, and the other end extends to the inner side wall of the tank body 1. Rake teeth 24 are provided on the bottom surface of the stirring rake 23.
[0042] When the stirring motor 21 rotates, it drives the stirring rake 23 to rotate through the stirring rod 22, so that the rake teeth 24 on the stirring rake 23 stir the underflow slurry at the bottom of the thickening chamber 11, and the underflow slurry is discharged from the discharge port 15 at the bottom of the thickener.
[0043] like Figure 3 and Figure 4 As shown, the rotating device 3 includes a rotating component 31 and a rotating motor 35. The rotating component 31 is annular and is sleeved on the upper part of the outer side of the pool body 1, allowing it to rotate relative to the pool body 1. Two support plates 32 extending towards the center of the shell are provided on the upper part of the rotating component 31. The two support plates 32 are arranged opposite to each other. Figure 2 .
[0044] A translation device 4 is provided on the support plate 32, and a limit block 321 is provided at one end of the support plate 32 near the middle of the pool body 1. The limit block 321 can limit the translation slider 42 to prevent it from derailing. (Refer to...) Figure 6 .
[0045] The translation device 4 includes a translation slide rail 41, a translation slider 42, and a telescopic cylinder 43. The translation slide rail 41 is fixedly mounted on the support plate 32 and extends radially along the pool body 1.
[0046] The translation slider 42 is slidably mounted on the translation rail 41. Three high-pressure nozzles 5 are mounted on the translation slider 42, and these three nozzles 5 are evenly arranged radially along the pool body 1. The outlets 521 of the high-pressure nozzles 5 face the bottom of the thickening chamber 11. Specifically, the outlet 521 of one high-pressure nozzle 5 located outside the translation slider 42 is inclined outwards towards the pool body 1, while the outlets 521 of the other two high-pressure nozzles 5 are inclined towards the center of the pool body 1. (Refer to...) Figure 6 .
[0047] In other embodiments, other numbers of high-pressure nozzles 5 may be provided on the translation slider 42, such as two, five or more.
[0048] The high-pressure nozzle 5 located outside the translation slider refers to the high-pressure nozzle 5 that is closest to the side wall of the pool body 1 among the three high-pressure nozzles 5 on the translation slider 42.
[0049] The high-pressure nozzles 5 on the outside can be used to flush the sediment at the corner of the inner wall of the pool 1 to prevent the sediment at the corner from not being cleaned properly. The other two high-pressure nozzles 5 can be used to flush the sediment accumulated on the bottom plate 12, so that the sediment on the bottom plate 12 can flow quickly to the discharge port 15 and be discharged from the discharge port 15.
[0050] The telescopic cylinder 43 is fixedly mounted on the support plate 32. One end is fixedly connected to the end of the support plate 32 near the rotating part 31, and the other end is fixedly connected to the translation slider 42. By extending and retracting the telescopic rod of the telescopic cylinder 43, the translation slider 42 can be driven to slide back and forth along the translation rail 41. This allows the high-pressure nozzle 5 on the translation slider 42 to uniformly wash the sediment on the bottom plate 12 from the outside to the center, improving the washing efficiency.
[0051] A rotating slide rail 37 is provided on the outer side wall of the pool body 1, which surrounds the outer perimeter of the pool body 1. Four rotating sliders 33 are evenly arranged on the inner side wall of the rotating component 31, and a driven rack 34 is provided on the outer side wall of the rotating component 31.
[0052] The rotating sliders 33 are slidably mounted on the rotating slide rail 37, and the four rotating sliders 33 are evenly distributed in a ring along the inner sidewall of the rotating member 31. In other embodiments, other numbers of rotating sliders 33 can be provided, such as three, six or more. The rotating member 31 can be supported by the rotating slide rail 37 and the rotating sliders 33, allowing the rotating member 31 to rotate relative to the pool body 1.
[0053] The rotating shaft of the rotating motor 35 is provided with a drive gear 36 that meshes with the driven rack 34. The rotating motor 35 can drive the rotating component 31 to rotate relative to the pool body 1.
[0054] When the rotating motor 35 drives the rotating component 31 to rotate, the rotating component 31 will reciprocate back and forth, and the rotation angle is 180°.
[0055] There are two rotating motors 35, which are arranged opposite each other on both sides of the pool body. In other embodiments, the number of rotating motors 35 can also be other, such as 1, 3 or more.
[0056] After the rake occurs, the high-pressure nozzle 5 is connected to the high-pressure water pipeline, which can spray high-pressure flushing water into the thickening chamber 11. The high-pressure water evenly washes the sediment on the bottom plate 12. The rotating motor 35 drives the rotating component 31 to rotate, and the telescopic cylinder 43 drives the translation slider 42 to slide back and forth along the translation rail 41. This allows the nozzle to rotate and slide back and forth at the same time, improving the flushing efficiency and flushing coverage area. The high-pressure water causes the sediment on the bottom plate 12 to be quickly turned up and collected at the discharge port 15. It is then discharged by the underflow pump 16, thus quickly discharging the rake sediment in the thickener.
[0057] like Figure 5 As shown, the bottom of the rotating slider 33 is provided with multiple universal balls 331, and the rotating slider 33 is slidably mounted on the rotating slide rail 37 via the universal balls 331. The universal balls 331 are existing technology, and their structure will not be described in detail here.
[0058] By sliding the rotating slider 33 onto the rotating slide rail 37 via the universal ball 331, friction can be reduced and the rotation efficiency of the rotating component 31 can be improved.
[0059] like Figure 7 and Figure 8 As shown, the high-pressure nozzle 5 includes a high-pressure nozzle 51 and a compression pipe 52. The high-pressure nozzle 51 is cylindrical, with an end cap 53 at the rear end and an air inlet 511 on the side wall. The front end gradually narrows to form a connecting port 512. The end cap 53 has a water inlet 531. The compression pipe 52 is a conical shell, with its flared end fixedly connected to the connecting port 512 and its narrowed end forming a water outlet 521.
[0060] The water inlet 531 and air inlet 511 of the high-pressure nozzle 5 are connected to the high-pressure flushing pipe and the compressed air pipe respectively through a rotating distribution plate.
[0061] The high-pressure nozzle 5 includes a high-pressure nozzle 51 and a compression pipe 52. It can be connected to a high-pressure water pipe through the water inlet 531 and to a compressed air pipe through the air inlet 511, so that high-pressure water and high-pressure air can enter the high-pressure nozzle 51. The compression pipe 52 is set in a conical shape, which can increase the water pressure and make the high-pressure flushing water spray out quickly from the water outlet 521, thereby improving the flushing efficiency of sedimentary minerals.
[0062] In use, crude potassium ore slurry is added to the thickening chamber 11 for concentration. The supernatant is discharged from the overflow port 14 through the overflow trough 13. The concentrated underflow slurry is discharged from the discharge port 15 and then through the underflow pump 16 under the stirring action of the stirring device 2. After the rake occurs, the underflow pump 16 is turned on, and the high-pressure nozzle 5 is connected to the high-pressure water pipe and the compressed air pipe respectively. The rotating part 31 is driven to rotate by the rotating motor 35. The telescopic cylinder 43 drives the translation slider 42 to slide back and forth along the translation rail 41, so that the nozzle rotates and slides back and forth at the same time. High-pressure flushing water is sprayed into the thickening chamber 11 through the high-pressure nozzle 5. The high-pressure water evenly washes the deposited ore on the bottom plate 12. The high-pressure water causes the deposited ore on the bottom plate 12 to turn up quickly and quickly collect at the discharge port 15 and be discharged through the underflow pump 16. The deposited ore rake in the thickener is quickly discharged. After the deposited ore is washed, normal production can be resumed.
[0063] This invention utilizes a rotating device 3 to rotatably mount a rotating component 31 onto the outside of the tank body 1. A support plate 32 extending towards the center of the housing is mounted on the rotating component 31, and a high-pressure nozzle 5 is mounted on the support plate 32. A rotating motor 35 is connected to the rotating component 31. After the thickener is rake-down, the high-pressure nozzle 5 is connected to a high-pressure water pipe, allowing high-pressure flushing water to be sprayed into the thickening chamber 11. The rotating motor 35 drives the rotating component 31 to rotate, which in turn drives the high-pressure nozzle 5 to rotate. The high-pressure water evenly flushes the sediment on the bottom plate 12, improving flushing efficiency and coverage. The high-pressure water rapidly stirs up the sediment on the bottom plate 12, collecting it at the discharge port 15 and discharging it via the underflow pump 16. This invention can quickly discharge the sediment from the thickener after rake-down, solving the problems of difficult, time-consuming, and labor-intensive cleaning of sediment after rake-down in existing thickeners, which affects production.
[0064] By setting a translation device 4 on the support plate 32, the high-pressure nozzle 5 is fixedly set on the translation slider 42. The translation slider 42 can be driven to slide back and forth along the translation rail 41 by the telescopic cylinder 43, so that the high-pressure nozzle 5 on the translation slider 42 can evenly wash the sediment on the bottom plate 12 from the outside to the center, improve the washing efficiency, and make the sediment on the bottom plate 12 flow quickly to the discharge port 15 and be discharged from the discharge port 15.
[0065] The high-pressure nozzle 5 includes a high-pressure nozzle 51 and a compression pipe 52. It can be connected to a high-pressure water pipe through the water inlet 531 and to a compressed air pipe through the air inlet 511, so that high-pressure water and high-pressure air can enter the high-pressure nozzle 51. The compression pipe 52 is set in a conical shape, which can increase the water pressure and make the high-pressure flushing water spray out quickly from the water outlet 521, thereby improving the flushing efficiency of sedimentary minerals.
[0066] A sawtooth-shaped overflow weir 131 is provided on the upper part of the side wall near the middle of the thickening chamber 11 of the overflow trough 13. This can block impurities in the slurry and prevent them from entering subsequent production equipment and causing pipeline blockage or equipment damage.
[0067] By setting a rotating slide rail 37 on the outer side wall of the pool body 1, the rotating component 31 is slidably set on the rotating slide rail 37 by multiple rotating sliders 33, which can support the rotating component 31. The driving gear 36 on the rotating motor 35 meshes with the driven rack 34 on the rotating component 31, and the rotating component 31 can be driven to rotate relative to the pool body 1 by the rotating motor 35.
[0068] By sliding the rotating slider 33 onto the rotating slide rail 37 via the universal ball 331, friction can be reduced and the rotation efficiency of the rotating component 31 can be improved.
[0069] By setting three high-pressure nozzles 5 on the translation slider 42, the outer high-pressure nozzles 5 can wash the sediment at the corner of the inner wall of the pool 1 to prevent the sediment at the corner from not being cleaned. The other two high-pressure nozzles 5 can wash the sediment accumulated on the bottom plate 12, so that the sediment on the bottom plate 12 can flow quickly to the discharge port 15 and be discharged from the discharge port 15.
[0070] It should be noted that the above embodiments are illustrative of the present invention and not intended to limit the present invention.
