Description

Technical Field

[0001] This invention relates to the field of praseodymium-neodymium oxide production, and more specifically, to an emulsion treatment apparatus for the extraction of rare earth praseodymium-neodymium oxide. Background Technology

[0002] In the rare earth extraction process, if the feed solution contains suspended solid particles, excessive amounts of impurities such as iron, silicon, and fluorine, or excessive saponification, tiny salt particles can easily form. With continuous stirring with the organic and aqueous phases, these particles can easily form colloidal substances, causing irreversible emulsification in the tank. When the emulsion in the tank is already affecting flow, the tank must be stopped and the emulsion removed.

[0003] In existing technologies, centrifugation is one method for processing emulsions. However, existing centrifugation equipment has low processing efficiency, is cumbersome to operate, and frequently suffers from liquid splashing.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this invention is to provide an emulsion treatment device for the extraction of rare earth praseodymium and neodymium oxides, which can effectively improve the efficiency of centrifugation, simplify operation, reduce the possibility of liquid splashing, greatly improve the stability and reliability of centrifugation, and make centrifugation easier to implement and promote.

[0006] The embodiments of the present invention are implemented as follows:

[0007] An emulsion processing device for rare earth praseodymium-neodymium oxide extraction includes: a shell, a centrifuge cylinder, and a collection cylinder.

[0008] The centrifuge tube is housed within the outer casing and is rotatably mounted on the inner bottom wall of the casing. The centrifuge tube is driven by a driver.

[0009] The centrifuge tube has side outlet holes on its side wall, which are arranged radially along the centrifuge tube. There are multiple side outlet holes, which are spaced apart along the height of the centrifuge tube. A sealing plate is provided at the end of the side outlet hole, and the sealing plate can move axially along the side outlet hole to control the opening and closing of the side outlet hole. The sealing plate is fitted with an elastic element, which is used to drive the sealing plate to fit against the end of the side outlet hole to close the side outlet hole.

[0010] The collection cylinder is located on the outer wall of the centrifuge cylinder, and the collection cylinder cover is located at the side outlet hole to collect the material flowing out from the side outlet hole.

[0011] Along the centrifuge cylinder from top to bottom, the elastic force of the elastic element in the side outlet hole at different heights increases progressively.

[0012] Furthermore, the elastic force of the elastic element is set such that when the centrifuge drum reaches a speed threshold, the material inside the centrifuge drum pushes open the sealing plate and enters the collection drum. Along the centrifuge drum from top to bottom, the speed threshold corresponding to the elastic element in the side outlet hole at different heights increases progressively.

[0013] Furthermore, a stop and a sliding rod are installed inside the side outlet.

[0014] The baffle is located at one end of the side outlet near the collection cylinder, and multiple baffles are evenly spaced along the circumference of the side outlet.

[0015] The slide rod is coaxially arranged with the side outlet hole and can be slidably fitted within the space formed by multiple stops. The end of the slide rod and the end of the stop block away from the inner wall of the side outlet hole are in contact with each other.

[0016] One end of the slide rod near the collection cylinder is fixedly connected to the sealing plate, which is located on the side of the stop block near the collection cylinder. The other end of the slide rod is fixedly connected to a limit block, and an elastic element abuts against the stop block and the limit block.

[0017] Furthermore, a recessed area is provided inside the centrifuge tube, formed by a depression in the inner wall of the centrifuge tube. The depth of the recessed area increases gradually from its edge towards its center. A side outlet is located in the center of the recessed area.

[0018] Furthermore, the inner diameter of the centrifuge tube increases from top to bottom.

[0019] Furthermore, a retaining ring is also provided inside the centrifuge tube. The retaining ring is coaxially arranged with the centrifuge tube and is located near the top of the centrifuge tube. The outer diameter of the retaining ring is adapted to the inner diameter of the centrifuge tube at the expected installation position.

[0020] Along the direction from the edge of the centrifuge tube towards its central axis, the distance from the surface of the retaining ring to the bottom of the centrifuge tube decreases.

[0021] Furthermore, the side outlet holes are evenly spaced along the circumference of the centrifuge cylinder. The emulsion treatment device also includes a reinforcing sleeve, which is ring-shaped around the centrifuge cylinder and coaxially fixedly connected to the centrifuge cylinder via connecting blades. The inner diameter of the reinforcing sleeve is larger than the outer diameter of the centrifuge cylinder, and the collection cylinder passes through the reinforcing sleeve and is fixedly fitted to it.

[0022] One end of the connecting blade is fixedly connected to the outer wall of the centrifuge tube and simultaneously to the outer wall of the collection tube. The other end extends circumferentially along the centrifuge tube and outwards. The other end of the connecting blade is fixedly connected to the inner wall of the reinforcing sleeve and simultaneously to the outer wall of the collection tube. The connecting blades are arranged in an array along the circumferential direction of the centrifuge tube.

[0023] Furthermore, the collection cylinder includes a cylinder body and a collection box. The cylinder body is connected to the centrifuge cylinder and passes through a reinforcing sleeve. The collection box is detachably fitted onto the cylinder body to seal the collection cylinder. A mesh plate is provided at the opening of the collection box, and the mesh plate is positioned close to the cylinder body.

[0024] Furthermore, a drainage groove is provided at the bottom of the outer casing, and the drainage groove extends continuously in a ring shape along the circumference of the reinforcing sleeve. The drainage groove is coaxially arranged with the reinforcing sleeve, and the lower end of the reinforcing sleeve extends into the drainage groove.

[0025] Furthermore, the collection cylinder also includes an air inlet pipe, a first valve body, a first valve core, a drive rod, a synchronizing rod, a second valve body, a second valve core, and a drain pipe.

[0026] The first valve body is located at the upper part of the cylinder and outside the reinforcing sleeve. The first valve core is fitted into the first valve body, and the drive rod is connected to the first valve core for controlling the first valve core. The intake pipe is connected to the first valve body.

[0027] The second valve body is located at the lower part of the cylinder and outside the reinforcing sleeve. The second valve core is fitted into the second valve body, and a synchronizing rod is connected between the first and second valve cores to control the second valve core to move synchronously with the first valve core. The drain pipe is connected to the second valve body.

[0028] The air inlet pipe and the liquid outlet pipe are configured such that after the first valve core and the second valve core are opened synchronously by controlling the drive rod, the air inlet pipe is connected to the cylinder body, and the liquid outlet pipe is also connected to the cylinder body.

[0029] The drain pipe extends circumferentially along the reinforcing sleeve and simultaneously extends toward the bottom end of the reinforcing sleeve. The drain pipe is attached to the outer wall of the reinforcing sleeve so that the opening of the drain pipe is located in the area between two adjacent collection cylinders.

[0030] The beneficial effects of the technical solutions in the embodiments of the present invention include:

[0031] The emulsion treatment device for rare earth praseodymium-neodymium oxide extraction provided in this embodiment of the invention gradually increases the pushing force on the sealing plate as the centrifugal speed increases at the start of centrifugation. Once the pushing force can overcome the elastic force of the elastic element, the sealing plate can be pushed open, opening the side outlet hole, and the material can enter the collection cylinder from the centrifuge cylinder through the side outlet hole.

[0032] As the centrifuge's rotational speed increases, the thrust on the sealing plate increases, causing the side outlets to open sequentially from top to bottom. Material preferentially enters the upper collection cylinder, then proceeds to the lower collection cylinder. This design facilitates the even distribution of material within the centrifuge across the collection cylinders at different heights. To ensure that material fills each collection cylinder sequentially, the centrifuge's speed can be gradually increased.

[0033] Once all the material has entered the collection cylinder, the rotation speed can be stabilized at the preset value, thus completing centrifugation within each collection cylinder. After centrifugation, the collection cylinder can be cleaned directly. The collection cylinder and centrifuge cylinder are separated by a sealing plate. During the cleaning of the collection cylinder, the material for the next centrifugation can be added to the centrifuge cylinder, improving the compatibility between process steps, reducing time waste, and increasing centrifugation efficiency.

[0034] During centrifugation, the material first enters each collection cylinder sequentially, and then undergoes thorough centrifugation. This ensures that the final, complete centrifugation is completed within the collection cylinder, preventing material splashing out of the centrifuge cylinder openings, significantly improving the stability and reliability of the centrifugation process. The emulsion treatment unit simplifies the centrifugation process and is easier to use.

[0035] Overall, the emulsion treatment device for rare earth praseodymium-neodymium oxide extraction provided in this embodiment of the invention can effectively improve centrifugation efficiency, simplify operation, reduce the possibility of liquid splashing, greatly improve the stability and reliability of centrifugation, and make centrifugation easier to implement and promote.

[0051] Example

[0052] Please refer to Figures 1-3 This embodiment provides an emulsion treatment device 1000 for rare earth praseodymium-neodymium oxide extraction. The emulsion treatment device 1000 includes: a shell 100, a centrifuge cylinder 200 and a collection cylinder 300.

[0053] The outer casing 100 is cylindrical and open at the top. It is understandable that a top cover can also be provided for the outer casing 100, but this will not be elaborated on here.

[0054] The centrifuge tube 200 is housed within the housing 100 and is rotatably mounted on the inner bottom wall of the housing 100. The centrifuge tube 200 is driven by a driver (not shown in the figure).

[0055] The centrifuge cylinder 200 has a side outlet hole 210 on its side wall, which is arranged radially along the centrifuge cylinder 200. There are multiple side outlet holes 210, which are distributed at intervals along the height direction of the centrifuge cylinder 200, that is, the side outlet holes 210 are distributed at different height positions of the centrifuge cylinder 200.

[0056] A sealing plate 220 is provided at the end of the side outlet 210. The sealing plate 220 is arranged perpendicular to the axial direction of the side outlet 210 and can move along the axial direction of the side outlet 210 to control the opening and closing of the side outlet 210. The sealing plate 220 is fitted with an elastic element 230, which is used to drive the sealing plate 220 to fit against the end of the side outlet 210 away from the axis of the centrifuge cylinder 200 to close the side outlet 210.

[0057] The collecting cylinder 300 is located on the outer wall of the centrifuge cylinder 200 and covers the side outlet hole 210. The collecting cylinder 300 and the outer wall of the centrifuge cylinder 200 form a closed space for collecting the material flowing out from the side outlet hole 210.

[0058] Along the centrifuge cylinder 200 from top to bottom, the elastic force of the elastic element 230 within the side outlet 210 at different heights increases progressively. Thus, in the height direction of the centrifuge cylinder 200, the elastic element 230 of the upper side outlet 210 requires only a small force to push it open, overcoming its elastic force to push the sealing plate 220 outwards and open the side outlet 210. However, for the lower side outlet 210, a greater force is required to push the elastic element 230; only with a greater force can the side outlet 210 be opened.

[0059] With this design, when centrifugation starts, as the rotation speed gradually increases, the thrust on the sealing plate 220 will become greater and greater until the thrust can overcome the elastic force of the elastic element 230, thus pushing the sealing plate 220 open and opening the side outlet 210. The material can then enter the collection cylinder 300 from the centrifuge cylinder 200 through the side outlet 210.

[0060] As the centrifuge drum 200 rotates at increasingly higher speeds, the thrust on the sealing plate 220 increases, causing the side outlet 210 to open sequentially from top to bottom. Material preferentially enters the upper collection cylinder 300, and then sequentially enters the lower collection cylinder 300. This design facilitates the even distribution of material within the centrifuge drum 200 among the collection cylinders 300 at different heights. To ensure that material fills each collection cylinder 300 sequentially, the centrifuge drum 200 can be gradually accelerated.

[0061] Once all the material has entered the collection cylinder 300, the rotation speed can be stabilized at the preset value, thus completing centrifugation within each collection cylinder 300. After centrifugation, the collection cylinder 300 can be cleaned directly. The collection cylinder 300 and the centrifuge cylinder 200 are separated by a sealing plate 220. During the cleaning of the collection cylinder 300, the material for the next centrifugation can be added to the centrifuge cylinder 200, improving the compatibility between process steps, reducing time waste, and improving centrifugation efficiency.

[0062] During centrifugation, the material first enters each collection cylinder 300 in sequence, and then undergoes thorough centrifugation. In this way, the final thorough centrifugation is completed within the collection cylinder 300, and no material splashes out from the opening of the centrifuge cylinder 200, which greatly improves the stability and reliability of the centrifugation process.

[0063] The emulsion treatment unit 1000 simplifies the operation of the centrifugation process and is easier to use.

[0064] Overall, the emulsion treatment device 1000 for rare earth praseodymium-neodymium oxide extraction can effectively improve centrifugation efficiency, simplify operation, reduce the possibility of liquid splashing, and greatly improve the stability and reliability of centrifugation, making centrifugation easier to implement and promote.

[0065] Specifically, the elastic force of the elastic element 230 can be set such that when the rotational speed of the centrifuge cylinder 200 reaches a speed threshold, the material inside the centrifuge cylinder 200 pushes open the sealing plate 220 and enters the collection cylinder 300. Along the centrifuge cylinder 200 from top to bottom, the speed thresholds corresponding to the elastic elements 230 at different heights in the side outlet holes 210 increase progressively, but are not limited to this. The speed thresholds corresponding to the elastic elements 230 at different heights in the side outlet holes 210 can be flexibly set according to actual needs.

[0066] Please combine Figures 1-4 In this embodiment, a stop block 240 and a slide bar 250 are provided inside the side outlet hole 210.

[0067] The baffle 240 is located at one end of the side outlet 210 near the collection cylinder 300. The baffle 240 is fixedly connected to the inner wall of the side outlet 210, and multiple baffles 240 are evenly spaced along the circumference of the side outlet 210.

[0068] The slide rod 250 is coaxially arranged with the side outlet hole 210 and slidably engaged in the space formed by multiple stops 240. The end of the slide rod 250 and the end of the stop 240 away from the inner wall of the side outlet hole 210 are in contact.

[0069] One end of the slide rod 250 near the collecting cylinder 300 is fixedly connected to the sealing plate 220, which is located on the side of the stop block 240 near the collecting cylinder 300. The other end of the slide rod 250 is fixedly connected to a limiting block 260, and an elastic element 230 abuts against the stop block 240 and the limiting block 260. Optionally, the elastic element 230 is a cylindrical spring, sleeved on the slide rod 250 and abutting against the stop block 240 and the limiting block 260, but not limited to this. Under the action of the elastic element 230, the sealing plate 220 fits against the end of the side outlet hole 210 near the collecting cylinder 300, sealing the side outlet hole 210. During centrifugation, the material pushes the sealing plate 220 into the collecting cylinder 300, thus entering the collecting cylinder 300.

[0070] Furthermore, a recessed area 270 is provided inside the centrifuge cylinder 200, which is formed by a recess in the inner wall of the centrifuge cylinder 200. The depth of the recessed area 270 increases progressively from its edge towards its center. A side outlet 210 is located in the center of the recessed area 270. The recessed area 270 is used to guide material inside the centrifuge cylinder 200 into the collection cylinder 300. The edge of the lowest recessed area 270 extends to the inner bottom wall of the centrifuge cylinder 200 to facilitate the full collection of material inside the centrifuge cylinder 200.

[0071] Along the centrifuge cylinder 200 from top to bottom, the inner diameter of the centrifuge cylinder 200 increases. In this way, during the centrifugation process, not only can the material be effectively prevented from splashing out of the opening of the centrifuge cylinder 200, but also, as the material enters the collection cylinder 300, the inner wall of the centrifuge cylinder 200 can guide the material towards the bottom of the centrifuge cylinder 200, which facilitates the full entry of the material into the collection cylinder 300.

[0072] A retaining ring 280 is also provided inside the centrifuge cylinder 200. The retaining ring 280 is coaxially arranged with the centrifuge cylinder 200 and is positioned near the top of the centrifuge cylinder 200. The outer diameter of the retaining ring 280 is adapted to the inner diameter of the centrifuge cylinder 200 at the intended installation position. The distance from the surface of the retaining ring 280 to the bottom of the centrifuge cylinder 200 decreases along the direction from the edge of the centrifuge cylinder 200 to its central axis. The retaining ring 280 further prevents material from splashing out of the opening of the centrifuge cylinder 200.

[0073] To improve the stability of the collection cylinder 300 during centrifugation, the side outlet holes 210 are evenly spaced along the circumference of the centrifuge cylinder 200. The emulsion treatment device 1000 also includes a reinforcing sleeve 400, which is circumferentially disposed around the centrifuge cylinder 200 and coaxially fixedly connected to the centrifuge cylinder 200 via connecting blades 410. The inner diameter of the reinforcing sleeve 400 is larger than the outer diameter of the centrifuge cylinder 200, and the collection cylinder 300 passes through the reinforcing sleeve 400 and is fixedly fitted with the reinforcing sleeve 400.

[0074] One end of the connecting blade 410 is fixedly connected to the outer wall of the centrifuge cylinder 200 and simultaneously to the outer wall of the collection cylinder 300. The other end extends circumferentially along the centrifuge cylinder 200 and outwards. The other end of the connecting blade 410 is fixedly connected to the inner wall of the reinforcing sleeve 400 and simultaneously to the outer wall of the collection cylinder 300. The connecting blades 410 are arranged in an array along the circumferential direction of the centrifuge cylinder 200.

[0075] Through this design, the reinforcing sleeve 400 can effectively stabilize the collecting cylinder 300, while the connecting blade 410, while assisting in stabilizing the collecting cylinder 300, can also improve the structural strength between the reinforcing sleeve 400 and the centrifuge cylinder 200. At the same time, it is easier to transmit the rotational force of the centrifuge cylinder 200 to the reinforcing sleeve 400, so that the reinforcing sleeve 400 and the centrifuge cylinder 200 rotate synchronously and stably, avoiding deformation of the collecting cylinder 300.

[0076] The collection cylinder 300 includes a cylinder body 310 and a collection box 320. The cylinder body 310 is connected to the centrifuge cylinder 200 and passes through the reinforcing sleeve 400. The collection box 320 is detachably fitted onto the cylinder body 310 to seal the collection cylinder 300. The cylinder body 310 passes just through the reinforcing sleeve 400. A mesh plate 330 is provided at the opening of the collection box 320, and the mesh plate 330 is positioned close to the cylinder body 310.

[0077] During centrifugation, the centrifuged material passes through the mesh plate 330 and enters the collection box 320, where it accumulates. After centrifugation, the collection box 320 can be removed from the cylinder 310 to drain the liquid. The collection box 320 contains the centrifuged material, thus achieving material separation. The mesh plate 330 does not interfere with the entry of material into the collection box 320 during centrifugation and also acts as a barrier to prevent the centrifuged material from falling out when the collection box 320 is removed.

[0078] To facilitate liquid discharge, a drainage groove 110 is provided at the bottom of the outer casing 100, which extends continuously in a ring shape along the circumference of the reinforcing sleeve 400. The drainage groove 110 is coaxially arranged with the reinforcing sleeve 400, and the lower end of the reinforcing sleeve 400 extends into the drainage groove 110. The outer casing 100 also has a drainage pipe 120 for draining the liquid in the drainage groove 110.

[0079] Please combine Figures 1-6 The collection cylinder 300 also includes an air inlet pipe 340, a first valve body 361, a first valve core 362, a drive rod 363, a synchronizing rod 364, a second valve body 365, a second valve core 366, and a drain pipe 350.

[0080] The first valve body 361 is located on the upper part of the cylinder 310 and outside the reinforcing sleeve 400. The first valve core 362 is fitted to the first valve body 361, and the drive rod 363 is connected to the first valve core 362 to control the first valve core 362. The air intake pipe 340 is connected to the first valve body 361 and its opening and closing are controlled by the first valve core 362. In this embodiment, the drive rod 363 controls the opening and closing by driving the first valve core 362 to rotate, but it is not limited to this.

[0081] The second valve body 365 is located at the lower part of the cylinder 310 and outside the reinforcing sleeve 400. The second valve core 366 is fitted into the second valve body 365, and the synchronizing rod 364 is connected between the first valve core 362 and the second valve core 366 to control the second valve core 366 to move synchronously with the first valve core 362. The drain pipe 350 is connected to the second valve body 365 and its opening and closing are controlled by the first valve core 362. In this embodiment, the drive rod 363 indirectly drives the second valve core 366 to rotate by driving the first valve core 362 to control the opening and closing, but it is not limited to this.

[0082] The air inlet pipe 340 and the liquid outlet pipe 350 are configured such that, after the first valve core 362 and the second valve core 366 are opened synchronously by the drive rod 363, the air inlet pipe 340 is connected to the cylinder 310, and the liquid outlet pipe 350 is also connected to the cylinder 310. The drive rod 363 can be driven manually or by a drive device.

[0083] In other embodiments of the present invention, the air intake pipe 340 is provided with a first control valve for controlling the opening and closing of the air intake pipe 340, and the drain pipe 350 is provided with a second control valve for controlling the opening and closing of the drain pipe 350.

[0084] When it is necessary to discharge the liquid phase in the collection cylinder 300, the air inlet pipe 340 and the liquid outlet pipe 350 are opened to smoothly discharge the liquid phase.

[0085] Furthermore, the liquid pipe extends circumferentially along the reinforcing sleeve 400 and simultaneously extends toward the bottom end of the reinforcing sleeve 400, and the drain pipe 350 is attached to the outer wall of the reinforcing sleeve 400 so that the opening of the drain pipe 350 is located in the area between two adjacent collection cylinders 300.

[0086] In this way, the discharged liquid flows along the outer wall of the reinforcing sleeve 400 to the drainage channel 110 in the area between the collection cylinders 300, greatly improving the stability of the drainage process and reducing liquid splashing. Furthermore, during the next centrifugation after drainage, a small amount of liquid will remain on the outer wall of the reinforcing sleeve 400. As the centrifuge cylinder 200 gradually accelerates (i.e., as the material in the centrifuge cylinder 200 sequentially enters the collection cylinder 300), the liquid recorded on the reinforcing sleeve 400 is thrown out and flows along the inner wall of the outer shell 100 to the drainage channel 110. To fully collect the liquid, the edge of the drainage channel 110 away from the centrifuge cylinder 200 extends to the inner wall of the outer shell 100.

[0087] In summary, the emulsion treatment device 1000 for rare earth praseodymium-neodymium oxide extraction provided in this embodiment of the invention can effectively improve centrifugation efficiency, simplify operation, reduce the possibility of liquid splashing, greatly improve the stability and reliability of centrifugation, and make centrifugation easier to implement and promote.

[0088] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
