Description

Technical Field

[0001] This utility model belongs to the technical field of high-fluorine mineral processing equipment, and in particular relates to an extraction device for high-fluorine mineral leachate. Background Technology

[0002] High-fluoride ores are the main source of smelting and separation enterprises, and require efficient processing. In view of the current fluoride content in raw carbonate ores in mines, a calcium hydroxide defluorination process is adopted. Calcium hydroxide is added under strong acid and high temperature conditions to remove fluoride ions from the feed solution, ensuring the normal operation of extraction and separation. In the purification and impurity removal of the leachate: when the fluoride ion concentration in the leachate is high, fluoride ions will also be extracted into the organic phase, thereby reducing the rare earth extraction capacity. Later, when the fluoride ion enrichment reaches a certain level, it will affect the yield and product quality. Therefore, the leachate cannot be directly used for extraction and needs to be purified and impurity removed. Calcium hydroxide is used to remove impurities such as F- through displacement.

[0003] A search revealed that publication number CN216808933U, with an application date of 2021.11.02, discloses an extraction device for solid waste leachate, relating to the field of solid waste leachate extraction technology. The device includes a mixing chamber and a settling tank. The mixing chamber is inclined with its left side lower than its right side. First legs are fixedly installed at the lower ends of both ends of the mixing chamber. A feed hopper is sealed and installed at the upper left end of the mixing chamber, and a connecting pipe is sealed and installed at the lower right end of the mixing chamber. The end of the connecting pipe furthest from the mixing chamber is sealed and connected to the upper part of the settling tank. A mixing motor is fixedly installed on the right end face of the mixing chamber.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing extraction devices for high-fluoride mineral leaching solutions use turbulent fans to ensure thorough mixing of the solution. However, because the solution is pushed upwards by the spiral blades, the upper and lower layers of solution cannot fully contact and mix, thus affecting the mixing effect.

[0006] 2. Existing extraction devices for high-fluoride mineral leaching solutions use cleaning blades to remove residual material from the inner wall of the feed pipe. However, this method cannot treat the inner wall of the settling tank, which still affects the purification of the extract. Therefore, we provide an extraction device for high-fluoride mineral leaching solutions to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide an extraction device for high-fluoride mineral leaching solutions. By setting up a ventilation component, a blower is used to spray air into the mixing cylinder. The air will generate bubbles in the solution and make it continuously roll, thereby accelerating the mixing efficiency and effect of the solution. Additionally, a rotating component and a cleaning component are used to scrape off the residual material on the inner wall of the settling tank and the feed pipe, which facilitates subsequent cleaning and improves the purity of the extract.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is an extraction device for high-fluoride mineral leaching solution, including a mixing cylinder and a settling tank disposed on one side thereon. A feed pipe is disposed at the center of the bottom of the settling tank. A ventilation component is disposed at the bottom of the mixing cylinder. A rotating component is disposed inside the feed pipe. A cleaning component is disposed inside the settling tank.

[0010] The ventilation assembly includes a blower installed below the mixing cylinder, and a first connecting pipe and a second connecting pipe installed at the blower outlet via a three-way connector;

[0011] The rotating assembly includes a motor mounted at the bottom of the feed tube and a rotating shaft mounted on the output shaft of the motor via a coupling;

[0012] The cleaning components include a lifting plate positioned directly above the settling tank, and electric push rods installed at both ends of the bottom of the lifting plate.

[0013] The present invention is further configured such that a feed inlet is provided at one end of the outer wall of the mixing cylinder, the mixing cylinder and the settling tank are connected by a pipe, and a conveying component is provided inside the mixing cylinder.

[0014] The present invention is further configured such that the other ends of the first connecting pipe and the second connecting pipe are both connected to the nozzle through pipe joints, and the nozzle is disposed on the inner wall of the mixing cylinder.

[0015] The present invention is further configured such that a first spline shaft is fixedly provided at the center of the top end of the rotating shaft, and a sealing plate is fixedly provided at the top of the outer wall of the rotating shaft.

[0016] The present invention is further configured such that a guide plate is provided at one bottom end of the sealing plate, and a rotating plate is provided on the outer wall of the rotating shaft.

[0017] The present invention is further configured such that a lifting shaft is rotatably installed at the bottom center of the lifting plate, and a second spline shaft is fixedly provided on the upper part of the outer wall of the lifting shaft, and the second spline shaft slides through the spline sleeve.

[0018] The present invention is further configured such that a spline groove is provided at the bottom center of the lifting shaft, and the spline groove is slidably sleeved on the outer wall of the first spline shaft.

[0019] The present invention is further configured such that a spline sleeve is rotatably installed in a bearing at the center of the top of the stationary barrel, a connecting frame is sleeved on the outer wall of the lifting shaft, and a scraper is installed on the outer wall of the connecting frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, by setting up a ventilation component, uses a fan to inject air into the mixing cylinder. The air generated bubbles in the solution and caused it to tumble continuously, thereby accelerating the mixing efficiency and effect of the solution. This solves the problem that existing extraction devices for high-fluoride mineral leaching solutions use a turbulent fan to mix the solution thoroughly, but this method prevents the upper and lower layers of solution from contacting due to the upward movement of the solution caused by the spiral blades, thus affecting the mixing effect of the solution.

[0022] 2. This utility model, by setting up a rotating component and a cleaning component, uses an electric push rod to adjust the height of the lifting shaft, so that the lifting shaft is connected to the rotating shaft. Under the action of the motor, the rotating plate and scraper rotate synchronously, thereby scraping off the residual material on the inner wall of the settling tank and the feed pipe, which facilitates subsequent cleaning and improves the purity of the extract. This solves the problem that existing extraction devices for high-fluoride mineral leaching solutions use cleaning blades to treat residual material on the inner wall of the feed pipe, but this method cannot treat the inner wall of the settling tank, which still affects the purification of the extract.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figures 1 to 3 This utility model is an extraction device for high-fluoride mineral leaching solution, including a mixing cylinder 100 and a settling tank 104 disposed on one side thereon. A feed pipe 105 is disposed at the center of the bottom of the settling tank 104. A ventilation component 200 is disposed at the bottom of the mixing cylinder 100. The ventilation component 200 includes a fan 201 installed below the mixing cylinder 100, and a first connecting pipe 202 and a second connecting pipe 203 installed at the air outlet of the fan 201 through a three-way connector.

[0035] Specifically, a feed inlet 101 is provided at one end of the outer wall of the mixing cylinder 100. The mixing cylinder 100 and the settling tank 104 are connected by a pipe 102. A conveying assembly 103 is provided inside the mixing cylinder 100. The other ends of the first connecting pipe 202 and the second connecting pipe 203 are connected to the nozzle 204 through pipe joints. The nozzle 204 is provided on the inner wall of the mixing cylinder 100.

[0036] Furthermore, the settling tank 104 is equipped with an observation window, and the three-part connector and pipe connector serve as pipe connections. The turbulence fan in the conveying component 103 and the mixing cylinder 100 are existing technologies, so they will not be described in detail here. The air inlet of the fan 201 is equipped with filtration measures.

[0037] The operation process of this embodiment is as follows: the organic phase solution and the high-fluorine mineral leaching solution are introduced into the mixing cylinder 100 through the feed port 101, and then the solution is conveyed and mixed under the action of the conveying component 103. At the same time, the blower 201 is started, and the blower 201 runs to draw in external air. The drawn-in air is sprayed into the mixing cylinder from the corresponding nozzle 204 through the first connecting pipe 202 and the second connecting pipe 203. The introduced air will generate bubbles in the solution and make it continuously roll, thereby accelerating the mixing efficiency and effect of the solution.

[0038] Example 2

[0039] Please see Figure 2 , Figure 4 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that a rotating assembly 300 and a cleaning assembly 400 are provided. The rotating assembly 300 includes a motor 301 installed at the bottom of the feed pipe 105 and a rotating shaft 302 installed on the output shaft of the motor 301 via a coupling. The cleaning assembly 400 includes a lifting plate 401 set directly above the settling tank 104 and electric push rods 402 installed at both ends of the bottom of the lifting plate 401. This solves the problem that existing extraction devices for high-fluoride mineral leaching solutions use cleaning blades to treat residual materials on the inner wall of the feed pipe, but this method cannot treat the inner wall of the settling tank, which still affects the purification of the extract.

[0040] Specifically, a first splined shaft 302a is fixed at the top center of the rotating shaft 302, and a sealing plate 303 is fixed at the top of the outer wall of the rotating shaft 302; a guide plate 303a is provided at one bottom end of the sealing plate 303, and a rotating plate 304 is provided on the outer wall of the rotating shaft 302; a lifting shaft 403 is rotatably installed at the bottom center of the lifting plate 401, and a second splined shaft 403a is fixed above the outer wall of the lifting shaft 403, which slides through the spline sleeve 404; a spline groove 403b is provided at the bottom center of the lifting shaft 403, and the spline groove 403b slides on the outer wall of the first splined shaft 302a; the spline sleeve 404 is rotatably installed in the bearing at the top center of the stationary bucket 104, a connecting frame 405 is sleeved on the outer wall of the lifting shaft 403, and a scraper 406 is installed on the outer wall of the connecting frame 405.

[0041] Furthermore, the first splined shaft 302a can be inserted into the splined groove 403b at the bottom of the lifting shaft 403 to play a docking and linkage role. The sealing plate 303, guide plate 303a, and rotating plate 304 are all existing technologies, so they will not be described in detail here. The second splined shaft 403a can slide inside the splined sleeve 404, and under the action of the splined sleeve 404, the lifting shaft 403 can be rotated. The scraper 406 contacts the inner wall of the settling bucket 104, which is convenient for cleaning the residual material.

[0042] The operation process in this embodiment is as follows: the mixed solution enters the settling tank 104 through the through pipe 102 and is settling for a period of time. Then, the solution is observed to separate into layers through the observation window. After the solution has separated into layers, it is discharged through the discharge pipe 105. After the solution in the settling tank 104 is discharged, the electric push rod 402 is activated. The telescopic end of the electric push rod 402 retracts, causing the lifting plate 401 to descend. The descent of the lifting plate 401 is synchronized with the lifting shaft 403 by the assistance of the second spline shaft 403a and the spline sleeve 404. The shaft descends, and the spline groove 403b at the bottom of the lifting shaft 403 is fitted onto the outer wall of the first spline shaft 302a, completing the docking of the lifting shaft 403 and the rotating shaft 302. Then, the motor 301 is started, and the output shaft of the motor 301 rotates, driving the rotating shaft 302 and the lifting shaft 403 to rotate synchronously through the coupling. This causes the scraper 406 on the rotating plate 304 and the connecting frame 405 to rotate synchronously, thereby scraping off the residual material on the inner wall of the settling tank 104 and the feed pipe 105, facilitating subsequent cleaning and improving the purity of the extract.
