Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of impurity removal of high-fluorine ore, and particularly relates to an impurity removal device for removing fluorine ions through displacement reaction of high-fluorine ore. BACKGROUND

[0002] In the processing of carbonate ore, the carbonate ore is dissolved by hydrochloric acid to obtain leaching liquor with high rare earth concentration and low impurity content, and then the leaching liquor is subjected to extraction, back extraction and other steps to obtain single chlorinated rare earth solution. However, when the fluorine ion concentration in the leaching liquor is high, the fluorine ions will also be extracted into the organic phase, thereby reducing the rare earth extraction capacity. The enrichment of fluorine ions to a certain extent will affect the yield and product quality. Therefore, the leaching liquor cannot be directly subjected to extraction operation, and calcium hydroxide needs to be used to remove fluorine ions and other impurities. In the displacement impurity removal process, the high-fluorine leaching liquor and calcium hydroxide are added to the impurity removal device by the staff, and the fluorine ions in the leaching liquor are removed through stirring. For example, the existing public document CN215103469U-a rare earth extraction impurity removal device and the existing public document CN113564388A-an automatic impurity removal device for rare earth processing both disclose an impurity removal device for rare earth production. The above-mentioned impurity removal device can realize the stirring impurity removal of high-fluorine leaching liquor, but the existing impurity removal device still has the following shortcomings in actual use: 1. The existing impurity removal device generally needs to add the leaching liquor and calcium hydroxide through the feeding port at the top of the impurity removal device, and then fully stir to realize impurity removal. Such feeding mode needs sufficient stirring to effectively react because the mixing of the two is not sufficient, thereby reducing the production efficiency and indirectly increasing the energy consumption. Moreover, because the leaching liquor removes excessive fluorine ions but not all fluorine ions, the staff is difficult to accurately grasp the added amount; 2. The existing impurity removal device is designed as an integrally formed tank. After the impurity removal reaction, part of the precipitate will be deposited and attached to the inner wall of the tank. After long-term use, dirt may even accumulate inside the tank, and the staff is difficult to effectively clean the inside of the tank, thereby indirectly increasing the labor intensity of the staff; Therefore, it is necessary to improve the existing technology to solve the above technical problems. SUMMARY

[0003] This section aims to summarize some aspects of the embodiments of the present application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of the specification to avoid obscuring the purpose of this section, abstract and title, and such simplifications or omissions cannot be used to limit the scope of the present application.

[0004] In view of the problems of low production efficiency and inconvenient feed control caused by the long-term stirring required by the existing impurity removal devices, a high-fluoride mineral displacement reaction impurity removal device for removing fluoride ions is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a purification device for removing fluoride ions by displacement reaction of high-fluoride minerals, comprising: an outer protective mechanism, including an outer protective cylinder, a base frame fixed on the outer side wall of the lower end of the outer protective cylinder, and a settling plate coaxially disposed below the outer protective cylinder; a cylinder cover is fixedly connected to the top surface of the outer protective cylinder by bolts; and a stirring mechanism, including a first conveying pipe fixedly connected at one end to the top surface of the cylinder cover, a stirring rod coaxially disposed inside the outer protective cylinder in a vertical direction, and a group of stirring blades symmetrically disposed on both sides of the stirring rod, with multiple stirring blades in the same group arranged in an array along the axial direction of the stirring rod; a linkage plate is fixedly sleeved on the stirring rod above the stirring blades, and two liquid storage sleeves of different diameters are concentrically fixed on the top surface of the linkage plate outside the stirring rod. The two liquid storage sleeves form a liquid storage cavity. One end of the first delivery pipe is connected to the liquid storage cavity. Two second delivery pipes are symmetrically connected to the first delivery pipe, and a pump body is installed on each of the two second delivery pipes. The inside of the stirring blade is provided with an L-shaped cavity. The bottom surface of the stirring blade is set as an inclined surface with the end away from the stirring rod inclined upward. Multiple liquid outlet holes communicating with the L-shaped cavity are arrayed along the long side of the stirring blade on the inclined surface. Multiple stirring blades and multiple connecting pipes in the same group are arranged alternately. The upper and lower sides of the stirring blade near the stirring rod are symmetrically fixed with second threaded sleeves communicating with the L-shaped cavity. The bottom surface of the linkage plate is connected and fixed with the first threaded sleeve. The end of the connecting pipe is connected and fixed with the first threaded sleeve and / or the second threaded sleeve through a fitting sleeve.

[0006] The beneficial effects of this invention are as follows: When using this impurity removal device, the high-fluoride leachate to be treated is first added through the feeding port on the cylinder cover. Then, according to the amount of leachate, a certain amount of calcium hydroxide is added to the storage chamber through one of the second conveying pipes. The calcium hydroxide in the storage chamber is conveyed into each L-shaped cavity through the connecting pipe and finally discharged from the outlet hole on the stirring blade. With the stirring of the stirring blade, the calcium hydroxide discharged from the outlet hole can fully and efficiently mix and react with the leachate, effectively improving the efficiency of the stirring reaction. The quantitative addition of calcium hydroxide in the storage chamber can achieve an effective reaction, ensuring that fluoride ions in the leachate are accurately precipitated. Overall, it has good practicality.

[0007] As a preferred embodiment of the impurity removal device for removing fluoride ions by high-fluoride mineral replacement reaction of the present invention, the stirring rod is rotatably connected to the cylinder cover through a rolling bearing, the upper end of the stirring rod is fitted into the output end of the motor, and the motor is fixedly connected to the top surface of the cylinder cover.

[0009] As a preferred embodiment of the impurity removal device for removing fluoride ions by high-fluoride mineral replacement reaction of the present invention, the stirring rod has multiple rectangular through slots arrayed along the axial direction on its side wall, and connecting sleeves are fixed on the side walls of the stirring rod at both ends of the rectangular through slots. One end of the stirring blade is fixed with an insert plate that is slidably sleeved in the connecting sleeve, and the insert plate and the connecting sleeve are fixed by bolts.

After the reaction is complete, the cylinder extends to move the settling plate downwards. Through the cooperation of the T-shaped clips and slots, the operator can remove the entire settling plate, making it convenient for the operator to clean the precipitate inside the device. This cleaning method is convenient and efficient, effectively cleaning the precipitate on the inner wall of the collection hood, effectively reducing the labor intensity of the operator, and has good overall practicality.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0030] Example 1 Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This is the first embodiment of the present invention. This embodiment provides a purification device for removing fluoride ions by displacement reaction of high fluoride minerals. When the purification device is in use, the leachate is added into the outer protective cylinder 101 through the feed port on the cylinder cover 101a, and calcium hydroxide is added into the storage chamber. The device is stirred by the stirring mechanism 200 to remove fluoride ions from the leachate.

[0031] Specifically, it includes an outer protective mechanism 100, comprising an outer protective cylinder 101, a base frame 102 fixed to the outer wall of the lower end of the outer protective cylinder 101, and a settling plate 103 coaxially disposed below the outer protective cylinder 101. A cylinder cover 101a is bolted to the top surface of the outer protective cylinder 101 to facilitate detachable connection of the cylinder cover 101a, and a feed inlet is provided on the cylinder cover 101a; and a stirring mechanism 200, comprising a first conveying pipe 201 fixedly connected at one end to the top surface of the cylinder cover 101a, and a stirring pipe coaxially disposed vertically on the outer protective cylinder. The stirring rod 202 inside 101 and the stirring blades 203 are symmetrically arranged on both sides of the stirring rod 202. Multiple stirring blades 203 in the same group are arranged in an array along the axial direction of the stirring rod 202. The stirring rod 202 is rotatably connected to the cylinder cover 101a through a rolling bearing. The upper end of the stirring rod 202 is fitted into the output end of the motor 202b, and the motor 202b is fixedly connected to the top surface of the cylinder cover 101a. The operation of the motor 202b drives the stirring rod 202 to rotate the stirring blades 203, thereby achieving stirring during the reaction.

[0032] See details Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a linkage disc 202a is fixedly sleeved on the stirring rod 202 above the stirring blade 203. Two liquid storage sleeves 202a-1 of different diameters are fixedly mounted on the top surface of the linkage disc 202a outside the stirring rod 202. The position between the two liquid storage sleeves 202a-1 forms a liquid storage cavity. One end of the first delivery pipe 201 is connected to the liquid storage cavity. Two second delivery pipes 201b are symmetrically connected to the first delivery pipe 201. A pump body 201b-1 is installed on each of the two second delivery pipes 201b. A third solenoid valve 201b-2 is fixedly installed on the second delivery pipe 201b between the first delivery pipe 201 and the pump body 201b-1. The two pump bodies 201b-1 are a gas pump and a liquid pump, respectively. A second solenoid valve 201a is fixedly installed on the free end of the first delivery pipe 201. When in use, the second solenoid valve 201a is closed, the third solenoid valve 201b-2 on the air pump is closed, and the third solenoid valve 201b-2 on the liquid pump is open. The liquid pump sequentially feeds calcium hydroxide into the storage chamber through the second delivery pipe 201b and the first delivery pipe 201. After the calcium hydroxide is metered, the third solenoid valve 201b-2 on the air pump opens and the third solenoid valve 201b-2 on the liquid pump closes. The air pump then blows air into the storage chamber to increase the air pressure, creating high pressure that forces the calcium hydroxide out. After the calcium hydroxide is completely discharged, both third solenoid valves 201b-2 close, and the second solenoid valve 201a opens. The high pressure in the storage chamber is then released through the first delivery pipe 201, achieving pressure relief. After pressure relief is complete, the above steps can be repeated for repeated production.

[0033] Furthermore, a first sealing ring 202a-2 with a vertical cross-section in the shape of a T is fixed on the top surface of the liquid storage sleeve 202a-1, and a first sealing groove 101a-1 for clearance fit of the first sealing ring 202a-2 is opened on the bottom surface of the cylinder cover 101a, thereby achieving the sealing performance between the first sealing ring 202a-2 and the cylinder cover 101a while the linkage disc 202a rotates freely. An oil seal groove 202a-3 is opened circumferentially on the top surface of the first sealing ring 202a-2, and the oil seal groove 202a-3 is filled with sealing oil, thereby improving the sealing performance of the fit.

[0034] See details Figure 4 and Figure 6 As shown, the stirring blade 203 has an L-shaped cavity 203a inside. The design of the L-shaped cavity 203a allows calcium hydroxide to flow into each stirring blade 203 without accumulating in the upper part of the stirring blade 203 of the stirring rod 202 and being discharged in a concentrated manner. The bottom surface of the stirring blade 203 is set as an inclined surface with the end away from the stirring rod 202 inclined upward. Multiple liquid outlet holes 203a-1 communicating with the L-shaped cavity 203a are arrayed on the inclined surface along the long side of the stirring blade 203. The liquid outlet holes 203a-1 on the inclined surface can be set to allow the stirring blade to flow into each stirring blade 203 without accumulating in the upper part of the stirring blade 202 and being discharged in a concentrated manner. When the blade 203 rotates, calcium hydroxide can be sprayed out in an outward-expanding manner. Multiple stirring blades 203 and multiple connecting pipes 204 are arranged alternately in the same group. The upper and lower sides of the stirring blade 203 near the stirring rod 202 are symmetrically fixed with a second threaded sleeve 203b that communicates with the L-shaped cavity 203a. The bottom surface of the linkage disk 202a is connected and fixed with a first threaded sleeve 202a-4. The end of the connecting pipe 204 is connected and fixed with the first threaded sleeve 202a-4 or / and the second threaded sleeve 203b through a fitting sleeve 204a, so as to realize a detachable connection between them. When in use, the calcium hydroxide in the storage chamber is discharged through the first threaded sleeve 202a-4 under high pressure, and is transported through the connecting pipe 204 to each L-shaped cavity 203a, and finally discharged from the outlet hole 203a-1 on each stirring blade 203, so as to achieve mixing and reaction with the leachate in the outer protective cylinder 101.

[0035] Additionally, it should be noted that this device also includes a controller (not shown in the attached diagram) for controlling various electrical components, and the controller is located in a position convenient for operators to use.

[0036] Example 2 Reference Figure 6 and Figure 9 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that, in order to facilitate better replacement and maintenance, the stirring blade 203 and the stirring rod 202 are made detachable.

[0037] Specifically, multiple rectangular through slots 202d are arrayed along the axial direction on the side wall of the stirring rod 202, and connecting sleeves 202d-1 are fixed on the side wall of the stirring rod 202 at both ends of the rectangular through slots 202d. One end of the stirring blade 203 is fixed with an insert plate 203c that is slidably sleeved in the connecting sleeve 202d-1, and the insert plate 203c and the connecting sleeve 202d-1 are fixed by bolts. When in use, the above-mentioned setting allows the insert plate 203c to be removed from the connecting sleeve 202d-1 by removing the bolts. This design facilitates the disassembly, replacement, and maintenance of the stirring blade 203.

[0038] Example 3 Reference Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 This is the third embodiment of the present invention. This embodiment is based on any of the above embodiments, but the difference is that in order to facilitate the cleaning of solid sediments inside the outer casing 101 by the staff and avoid affecting the overall production efficiency of the device, this embodiment is proposed.

[0039] Specifically, a base cylinder 101b is coaxially arranged inside the lower end of the outer casing 101 for rotatably connecting to the lower end of the stirring rod 202. A flow guide shroud 101b-1 is fixed circumferentially on the top surface of the side plate of the base cylinder 101b. The vertical section of the flow guide shroud 101b-1 is inclined, allowing it to guide sediment towards the outside of the base cylinder 101b. The inclined upper end is positioned near the stirring rod 202. Filter holes 101b-2 are arrayed circumferentially on the side wall of the base cylinder 101b, allowing the sediment to pass through the outer side of the base cylinder 101b. The solution enters the inner side of the base cylinder 101b, while the precipitate is located on the outer side of the base cylinder. A collection cover 103c that fits against the side wall of the outer protective cylinder 101 is fixedly installed circumferentially on the top surface of the settling plate 103. The collection cover 103c can be used for the attachment of the precipitate. A liquid outlet pipe 101b-4 that communicates with the inside of the base cylinder 101b is fixedly installed on the bottom surface of the base cylinder 101b. The liquid outlet pipe 101b-4 is used for the discharge of liquid located inside the base cylinder 101b. A first solenoid valve 101b-5 is fixedly installed on the liquid outlet pipe 101b-4. The first solenoid valve 101b-5 is used to control the opening and closing of the liquid outlet pipe 101b-4. A second sealing ring 101b-6 is fixedly provided circumferentially on the bottom surface of the chassis cylinder 101b, a third sealing ring 102a is fixedly provided circumferentially on the bottom surface of the base frame 102, and a second sealing groove 103d is provided circumferentially on the top surface of the settling plate 103 for clearance fit between the second sealing ring 101b-6 and / or the third sealing ring 102a, and a sealing ring 103d-1 is interference fitted in the second sealing groove 103d, thereby achieving the sealing performance of the fit between the settling plate 103 and the chassis cylinder 101b and the outer protective cylinder 101; When in use, after the precipitate particles are produced by the reaction of the leachate and calcium hydroxide, the precipitate particles fall into the position between the collection hood 103c and the bottom cylinder 101b under the action of centrifugal force generated by the stirring blade 203 and the guidance of the flow guide hood 101b-1. The liquid thrown out under the action of centrifugal force flows back into the bottom cylinder 101b through the filter hole 101b-2 and is finally discharged from the liquid outlet pipe 101b-4. The precipitate accumulates and adheres to the position between the collection hood 103c and the bottom cylinder 101b. The staff only needs to remove the settling plate 103 to clean out the precipitate.

[0040] Furthermore, the chassis cylinder 101b is fixedly connected to the inner wall of the outer protective cylinder 101 by a plurality of fixing plates 101b-3 arranged in a circumferential array, and the collection cover 103c is provided with a compensation groove 103c-1 for the fixing plates 101b-3 to slide through.

[0041] Furthermore, a scraper 202c is symmetrically fixed on the lower end side wall of the stirring rod 202 for adhering to the inner bottom surface of the chassis cylinder 101b. The scraper 202c can scrape off a small amount of particles deposited on the inner bottom surface of the chassis cylinder 101b.

[0042] Example 4 Reference Figure 2 , Figure 3 , Figure 4 and Figure 8 This is the fourth embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that in order to facilitate the removal of the settling plate 103 more conveniently and reduce the labor required to remove the settling plate 103, this embodiment is proposed.

[0043] Specifically, mating blocks 103e are symmetrically fixed on the side wall of the settling plate 103. A mating plate 103a is provided below the mating blocks 103e. A T-shaped retaining strip 103e-1 is fixed on the bottom surface of the mating blocks 103e. A retaining groove 103a-3 with one end closed is provided on the top surface of the mating plate 103a for clearance mating with the T-shaped retaining strip 103e-1, thereby realizing a detachable connection between the mating plate 103a and the mating blocks 103e. A cylinder 103a-1 is fixed on the top surface of the mating plate 103a, and the fixed section of the cylinder 103a-1 is fixedly sleeved on the base frame 102. Universal wheels 103b are symmetrically fixed on the bottom surface of the settling plate 103. T-shaped columns 103a-2 are symmetrically fixed on the mating plates 103a on both sides of the cylinder 103a-1, and the T-shaped columns 103a-2 are slidably sleeved on the base frame 102 to realize the limiting guidance of the cylinder 103a-1 during extension and retraction. When in use, the above-mentioned device allows the settling plate 103 to move downward by extending the cylinder 103a, thereby removing the entire collection cover 103c from the outer protective cylinder 101. At this time, the operator only needs to pull the settling plate 103 out from the opening end of the slot 103a-3, and then move it with the universal wheel 103b to finally move the settling plate 103 out, which facilitates the cleaning and collection of the sediment on the settling plate 103.
