The device is characterized by further comprising a pushing plate 7, wherein the extraction tank body 2 is fixedly connected with three pushing plates 7, the pushing plates 7 positioned at the bottom of the extraction tank body 2 are provided with two telescopic plates 7a, non-rare earth impurities pushed by the scraping strip I5 and the collecting plates 6 are pushed to the outer sides of the two collecting plates 6 through the telescopic plates 7a, and the scraping strip I5 and the collecting plates 6 cannot be brought out by the non-rare earth impurities pushed to the bottom center of the extraction tank body 2 when the two separation plates 3 are prevented from moving back to reset.
The expansion plate 7a is made of rubber, when the expansion plate 7a pushes the non-rare earth impurities pushed by the scraping strip I5 and the collecting plate 6 to the outer side of the collecting plate 6, the expansion plate 7a is made of rubber, so that the scraping strip I5 and the collecting plate 6 can continuously move through the expansion plate 7a when the scraping strip I5 and the collecting plate 6 are in contact with the expansion plate 7a, the non-rare earth impurities are pushed to the opposite sides of the two collecting plates 6 comprehensively, and the non-rare earth impurities are prevented from remaining on the scraping strip I5 and the collecting plate 6.

The working steps of the above embodiment are: firstly, the partition plate 3 and all parts connected with the partition plate are driven to move in opposite directions through the sliding block 102, when the fixed strip 4 on the partition plate 3 is contacted with the left side wall and the right side wall of the extraction tank body 2, the sliding block 102 stops moving, the end part of the partition plate 3 is close to the left side wall and the right side wall of the extraction tank body 2, then the rare earth solution and the extraction solution are manually added into the extraction tank body 2, then the stirring impeller 1 is driven to move downwards through a moving device externally connected with the stirring impeller 1, when the stirring impeller 1 covers the extraction tank body 2, the stirring impeller 1 stops moving, then the solution is stirred through the stirring impeller 1, the rare earth solution reacts with the extraction solution in the stirring process, so that non-rare earth impurities in the rare earth solution are separated out, after the stirring is finished and is kept for a period of time, the solution is layered, the non-rare earth impurities are precipitated, then the solution on the upper layer is pumped out through a pump, however, when the upper solution is extracted, the lower solution is extracted together, so that the purity of the extracted upper solution is lower, before the upper solution is extracted, the stirring impeller 1 is driven to move upwards by a moving device externally connected with the stirring impeller 1, when the stirring impeller 1 moves to the upper part of the extraction tank body 2, the stirring impeller 1 stops moving, and then the two separation plates 3 are driven to move in opposite directions by the sliding block 102, in this description, the rare earth solution and the extraction solution added into the extraction tank body 2 are in a certain proportion, so that the intersection part of solution layering is always positioned at the middle layer of the extraction tank body 2, and the separation plate 3 is positioned at the middle layer of the extraction tank body 2, so that the part of solution layering is positioned in the separation plate 3, and the attention is paid to that the intersection part of the solution is stirred when the separation plate 3 moves, but the separation plate 3 has a certain height, even if the intersection part of the solution fluctuates when the partition plate 3 moves, the stirring position of the solution is in the partition plate 3, so that the fluctuation of the intersection part of the solution does not affect the layering position of the solution when the partition plate 3 moves, when the partition plate 3 is mutually attached, the solution is divided into an upper layer, a lower layer and an intersection layer by the partition plate 3, the solution at the intersection layer is mixed solution of rare earth solution and extraction solution, the mixed solution is less in quantity, and then the solution at the upper layer, the lower layer and the intersection layer are simultaneously extracted together by a plurality of pumps, and the pumps are separated by the partition plate 3, so that the pumps cannot extract the solutions at different layers, thereby solving the problem that the prior art easily extracts the solutions at the lower layer together when extracting the solution at the upper layer, leading to lower purity of the extracted upper layer solution, and leading to the solution to be extracted together, thereby increasing the speed of extracting the solution;
it should be noted that after the solution of the intersection layer is extracted, the solution is conveyed into an external storage container, so that the solution is layered in the storage container, and as the mixed solution of the intersection layer is less, the rare earth solution and the extraction solution are respectively extracted manually after the solution is layered, and when the solution is extracted, non-rare earth impurities are filtered out by a filtering device, so that the extracted solution is prevented from containing non-rare earth impurities, and the purity of the solution is ensured;
further, in the process of extracting the rare earth solution, although precipitated non-rare earth impurities are precipitated, in the process of precipitating the non-rare earth impurities, part of the non-rare earth impurities are adhered to the inner wall of the extraction tank body 2, and the rare earth solution containing the non-rare earth impurities can cause emulsification of the extractant and increase of three-phase matters so as to influence the effect of subsequent extraction and separation, so that the non-rare earth impurities are required to be scraped after the solution is extracted, but because the non-rare earth impurities adhered to the extraction tank body 2 can be gradually accumulated so as to form a thicker non-rare earth impurity layer, the non-rare earth impurities adhered to the extraction tank body 2 are difficult to clean after the solution is extracted, therefore, in the process of moving the partition plate 3 in the opposite direction, the partition plate 3 can drive the scraping strip I5 and the scraping strip II 12 to move in the opposite direction, and when the scraping strip I5 and the scraping strip II 12 contact the adhered non-rare earth impurities, the scraping strips I5 and II 12 can scrape non-rare earth impurities, so that in the process of the opposite movement of the separation plate 3, the scraping strips I5 and II 12 can scrape the non-rare earth impurities on the front and rear inner side surfaces and the inner lower side surfaces of the extraction tank body 2, the non-rare earth impurities scraped by the scraping strips II 12 can be deposited and fall onto the inner lower side of the separation plate 3, meanwhile, the corresponding ropes I9 are pulled by the winding wheel I8 to drive the scraping strips III 11 to move on the extraction tank body 2 to scrape the non-rare earth impurities on the left side surface and the right side surface of the extraction tank body 2, and the lugs 224 are driven to move in the process of the opposite movement of the separation plate 3 to enable the scraping strips IV 221 to move up and down in a reciprocating manner, the spring telescopic rods 223 are stretched and reset in a reciprocating manner, so that the scraping strips IV 221 scrape the left side surface and the right side surface of the extraction tank body 2 in the separation plate 3, thereby pre-scraping non-rare earth impurities adhered to the inner wall of the extraction tank body 2, and avoiding that the solution in the extraction tank body 2 is difficult to scrape the non-rare earth impurities adhered to the inner wall of the extraction tank body 2 after being extracted, so that the non-rare earth impurities remain on the inner wall of the extraction tank body 2;
meanwhile, when the non-rare earth impurities adhered to the inner wall of the extraction tank body 2 are pre-scraped, the solution in the extraction tank body 2 is not extracted, so that the pre-scraped non-rare earth impurities are mixed in the solution, so that part of scraped non-rare earth impurities are adhered to the inner wall of the extraction tank body 2 again, after the solution in the extraction tank body 2 is extracted, a layer of non-rare earth impurities can be adhered to the inner wall of the extraction tank body 2 again, therefore, when the sliding block 102 drives the separation plate 3 and all parts connected with the separation plate to move back and reset, the scraping strips I5 and II 12 again scrape the non-rare earth impurities adhered to the inner wall of the extraction tank body 2, and meanwhile, when the convex block 224 follows the separation plate 3 to reset, the scraping strips IV 221 are extruded again, so that the scraping strips IV 221 are repeatedly moved up and down again, and when the separation plate 3 is reset, the corresponding rope I9 is controlled to pull the winding wheel I8, so that the scraping strips III 11 are reset to scrape the non-rare earth impurities again, and the non-rare earth impurities on the inner wall of the extraction tank body 2 is completely scraped again;
it should be noted that in the process of moving the two separation plates 3 in opposite directions, the scraping strip I5 scrapes the non-rare earth impurities precipitated at the bottom of the extraction tank body 2, and along with the movement of the separation plates 3, the scraping strip I5 pushes the non-rare earth impurities precipitated at the bottom of the extraction tank body 2 together with the collecting plate 6, so that the non-rare earth impurities are largely remained at the bottom center of the extraction tank body 2, when the two separation plates 3 are contacted, the lower pushing plate 7 applies extrusion to the collecting plate 6, so that the collecting plate 6 rotates in a direction far away from the lower pushing plate 7, and pushes the scraping strip I5 and the non-rare earth impurities pushed by the collecting plate 6 to the opposite sides of the two collecting plates 6 through the lower pushing plate 7, so that when the two separation plates 3 are reset in opposite directions, the scraping strip I5 and the collecting plate 6 cannot push the non-rare earth impurities pushed to the bottom center of the extraction tank body 2, and a large amount of non-rare earth impurities remain at the bottom center of the extraction tank body 2, and along with the continued movement of the separation plates 3, the scraping strip I5 pushes the telescopic plate 7a, so that the telescopic plate 7a is adapted to the collecting plate 7 and the non-rare earth impurities pushed by the scraping strip I5 and the collecting plate 6 are completely attached to the bottom of the collecting plate 6, and the non-rare earth impurities are prevented from entering the non-rare earth impurities on the bottom of the collecting plate 6, and the non-rare earth impurities on the side of the collecting plate 7 is completely attached to the side, and the bottom side of the collecting plate 6;
subsequently, the scraped non-rare earth impurities are collected to the left end and the right end of the extraction tank body 2 through the back movement of the fixing strip 4 and the scraping strip I5, when the partition plate 3 is completely reset, the air suction device externally connected with the air suction strip 10 at the lower part sucks air to the air suction strip 10, so that the non-rare earth impurities are sucked out, the non-rare earth impurities are further removed, and the problems that the extraction agent is emulsified, three-phase matters are increased and the extraction and separation effects are influenced due to the fact that the non-rare earth impurities are contained in the extraction tank body 2 during the subsequent extraction are prevented;
it should be noted that non-rare earth impurities in the solution above the extraction tank body 2 will precipitate and fall onto the upper side of the separation plate 3, non-rare earth impurities scraped off by the scraping strip ii 12 will precipitate and fall onto the inner lower side of the separation plate 3, then when the two separation plates 3 are moved and stuck in opposite directions, the separation plate 3 will contact with the corresponding pushing plate 7, thereby pushing the non-rare earth impurities precipitated on the upper side and inner lower side of the two separation plates 3 to the opposite sides of the two separation plates 3 by the corresponding pushing plate 7 for a certain distance, thereby avoiding the problem that the non-rare earth impurities at the end of the separation plate 3 cannot be removed when the suction strip 10 sucks the non-rare earth impurities out, and when the separation plate 3 is moved and reset, the non-rare earth impurities on the separation plate 3 are scraped off by the corresponding suction strip 10 and collected at the suction inlet of the corresponding suction strip 10, thereby facilitating the complete suction of the rare earth impurities on the separation plate 3.
Example 2
On the basis of the embodiment 1, as shown in fig. 4-5, the device also comprises a poking unit; the stirring unit comprises a rotating plate 201, a rope II 202 and a winding wheel II 203; each fixing strip 4 is rotationally connected with eight rotating plates 201 through torsion springs; a plurality of four winding wheels II 203 which are distributed in a rectangular shape are fixedly connected on the opposite sides of the two separation plates 3; all the rotating plates 201 on each fixing strip 4 are fixedly connected with a rope II 202, and the other end of the rope II 202 penetrates through the separation plate 3 and is fixedly connected with a corresponding winding wheel II 203.
