[0032] The moving assembly includes: an electric lifting column 101, a guide rail 102 and an electric slider 103; there are two electric lifting columns 101, and each electric lifting column 101 is provided with an electric moving wheel; the electric moving wheel is driven by a drive motor; the lifting parts of all electric lifting columns 101 are commonly connected to the guide rail 102; the electric slider 103 is slidably connected to the guide rail 102; the stirring motor 2 and the DD motor 4 are both connected to the electric slider 103.

[0033] It also includes a moving roller 1 701, a moving roller 2 801, a limit block 9 and an elastic member 10; the connecting rod 5 is a spring telescopic rod; the telescopic end of the connecting rod 5 is fixedly connected to the connecting block 6; two moving rollers 1 701 are rotatably connected to the connecting block 6; the rightmost ends of the two moving rollers 1 701 are flush with the right side of the triangular block 7; the opposite back surfaces of the two inclined plates 8 are each rotatably connected to a moving roller 2 801, and the lowermost end of the moving roller 2 801 is flush with the lower side of the inclined plate 8; each moving roller 1 701 is slidably connected to a limit block 9; each moving roller 1 701 is plugged into the corresponding inclined plate 8; an elastic member 10 is connected between each limit block 9 and each inclined plate 8; the elastic member 10 is a spring.

[0034] Two of the inclined surfaces of the triangular block 7 are in contact with the corresponding inclined plates 8 respectively; and a limiting ball head 702 is connected to the bottom of each moving roller 701 .

[0035] It also includes a mounting frame 11; one of the inclined plates 8 is fixedly connected to the mounting frame 11; a rubber scraper 1101 is mounted on the mounting frame 11; the rubber scraper 1101 is provided with a through hole that matches the shape of the stirring blade 3.

[0036] A counterweight 1102 is installed on the side of the installation frame 11 away from the inclined plate 8 to balance the weight on both sides of the installation frame 11.

[0037] The bottom of the triangular block 7 is tapered, which facilitates downward insertion into the rare earth.

[0038] The conical bottom of the triangular block 7 is provided with a ball head to avoid damage to the rubber liner when inserting downward.

[0039] The upper and lower inlet edges of the through hole of the rubber scraper 1101 are chamfered to facilitate the stirring blade 3 to penetrate the through hole.

[0040] The steps of stirring the rare earth in the smelting pool using the present invention are as follows:

[0041] The electric lifting column 101 of the present invention is initially in a raised state, the bottom of the stirring blade 3 is higher than the smelting pool, the inclined plate 8 is located at the bottom of the triangular block 7, and is limited by the limiting ball head 702 so as not to fall off the triangular block 7. During stirring, the worker controls the electric moving wheel of the electric lifting column 101 to move the present invention to the smelting pool, controls the stirring motor 2 to work, drives the stirring blade 3 to rotate, and then controls the electric lifting column 101 to descend. During the process, the bottom of the inclined plate 8 contacts the upper right edge of the smelting pool, so that the inclined plate 8 stays at the upper right edge of the smelting pool, and the rotating stirring blade 3 moves down to the rare earth in the smelting pool, and the triangular block 7 and the moving roller 1 701 are inserted downward into the rare earth. The inclined plate 8, the limiting block 9 and the elastic member 10 remain stationary relative to the triangular block 7 and the moving roller 1 701. According to the height specification of the smelting pool, the electric lifting column 101 is controlled to descend so that the stirring blade 3 is more than 5 cm away from the bottom surface of the smelting pool, and the bottom of the triangular block 7 contacts the bottom of the smelting pool. Figure 1 For reference, the electric slider 103 is controlled to move to the right along the guide rail 102, so that the side of the triangular block 7 facing the right side of the smelting pool is in contact with the right side wall of the smelting pool. Then the worker controls the electric moving wheel to make the electric lifting column 101 drive the connected parts to move backward. During the process, the rotating stirring blade 3 stirs the rare earth. At the same time, the side of the triangular block 7 corresponding to the forward direction scrapes the rare earth on the right side wall of the inclined plate 8 and guides it to the stirring blade 3. At the same time, the inclined plate 8 in the forward direction scrapes the rare earth on the upper right side of the smelting pool and guides it back to the smelting pool to participate in the stirring.

[0042] After the rare earth scraping on the right side wall of the smelting pool is completed, the stirring blade 3, the triangular block 7 and the inclined plate 8 are moved close to the rear side wall of the smelting pool. After the triangular block 7 reaches the rear end of the right side wall and cannot move further, the electric lifting column 101 is controlled to retreat forward, so that there is a distance of more than 10 cm between the triangular block 7 and the rear side wall. Then, looking from top to bottom, the DD motor 4 is controlled to drive the connecting rod 5, the connecting block 6, the triangular block 7 and the inclined plate 8 to rotate counterclockwise 90 degrees, and then the electric lifting column 101 is controlled to drive the stirring blade 3, the triangular block 7 and the inclined plate 8 close to the rear side wall, so that the triangular block 7 fits with the rear side wall of the smelting pool. The inclined plate 8 is fitted with the upper edge of the rear side of the smelting pool, and then the electric slider 103 is controlled to move to the left, and the stirring blade 3 stirs the rare earth near the rear side wall of the smelting pool. At the same time, the triangular block 7 scrapes the rare earth on the rear side wall of the smelting pool to guide it to the stirring blade 3, and the inclined plate 8 scrapes the rare earth on the upper edge of the rear side of the smelting pool back to the smelting pool; and so on, by moving the electric lifting column 101 back and forth and moving the electric slider 103 left and right, the present invention processes the remaining two side walls of the smelting pool, and then controls the stirring blade 3 to move to the middle of the smelting pool to fully stir the rare earth in the smelting pool.

[0043] The smelting pool is usually paved with a rubber pad. During the movement of the triangular block 7, the moving roller 701 in the moving direction contacts the folds before the triangular block 7. The rolling moving roller 701 will press over the folds. At the same time, the moving roller 701 is lifted up by the folds and away from the side wall of the smelting pool. The moving roller 701 drives the connecting block 6 to approach the connecting rod 5. The connecting block 6 compresses the connecting rod 5. At the same time, the reaction force of the connecting rod 5 acts on the connecting block 6, so that the moving roller 701 is pressed against the rubber pad of the side wall of the smelting pool when rolling. The triangular block 7 is also close to the rubber pad of the side wall of the smelting pool. Pad surface; when the inclined plate 8 moves, the moving roller 2 801 in its moving direction contacts the wrinkles before the inclined plate 8 and rolls over the wrinkles, and the moving roller 2 801 drives the corresponding inclined plate 8 to move upward and squeeze the elastic member 10, while the top of the limit block 9 at the other end of the elastic member 10 is restricted by the connecting block 6 and cannot move, and then the reaction force of the elastic member 10 acts on the inclined plate 8, so that the inclined plate 8 and the moving roller 2 801 are tightly attached to the upper edge of the rubber pad when moving; it should be noted that after the triangular block 7 and the moving roller 1 701 are inserted downward into the rare earth, the limit block 9 contacts the connecting block 6.

[0044] After the stirring work is completed, the stirring motor 2 is controlled to stop working, the stirring blade 3 stops rotating, and is aligned with the mounting frame 11, as shown in FIG. Figure 3The electric lifting column 101 shown in the figure controls the stirring blade 3 and the triangular block 7 to move upward. During the process, the dead weight of the inclined plate 8 keeps it at the upper edge of the smelting pool, and the triangular block 7 will pass through the inclined plate 8 upward. The limit block 9 and the elastic member 10 remain stationary relative to the moving roller 701. The rare earth adhered to the surface of the triangular block 7 and the moving roller 701 is scraped off by the lower side of the inclined plate 8 and returned to the smelting pool; at the same time, the stirring blade 3 will pass through the through hole of the rubber scraper 1101 on the mounting frame 11, and the rare earth adhered to the stirring blade 3 is scraped off by the rubber scraper 1101 and returned to the smelting pool. Finally, the limit ball head 702 contacts the bottom of the inclined plate 8, so that the triangular block 7 cannot continue to move upward relative to the inclined plate 8. Workers can then use tools such as scrapers to scrape the small amount of residual rare earth at the bottom of the inclined plate 8 and the rubber scraper 1101 back to the smelting pool.

[0045] According to the above steps, we know that the present invention has the following effects:

[0046] In view of the existing situation that when rare earths in a smelting pool are stirred, the stirring equipment cannot be too close to the side wall of the smelting pool, resulting in that part of the rare earth adhering to the side wall cannot participate in the stirring, making the reaction of this part of the rare earth insufficient, and it is easy to harden and difficult to remove from the side wall. In the present invention, during the stirring process, the triangular block 7 is attached to the side wall of the smelting pool, and the rare earth on the side wall is scraped off and guided to the stirring blade 3 to participate in the stirring, thereby avoiding that part of the rare earth adhering to the side wall cannot participate in the stirring; and when loading and unloading materials into the smelting pool, the rare earth that falls on the upper edge of the smelting pool is scraped back into the smelting pool through the inclined plate 8, thereby avoiding waste of rare earth resources.

[0047] Usually, a rubber liner is laid in the smelting pool to prevent leakage in the smelting pool during the chemical smelting process and to facilitate the subsequent cleaning of the smelting pool. However, the rubber liner laid in the smelting pool has wrinkles, which affects the moving scraping work of the triangular block 7 and the inclined plate 8 along the side wall and upper edge of the smelting pool. Then, the moving roller 1 701 and the moving roller 2 801 press over the wrinkles before the triangular block 7 and the inclined plate 8, and drive the triangular block 7 and the inclined plate 8 to adaptively avoid the wrinkles, so that the triangular block 7 and the inclined plate 8 can smoothly carry out the moving scraping work.

[0048] Rare earth resources are precious. After the stirring work is completed, some rare earth will remain on the stirring blade 3 and the triangular block 7 that are deeply immersed in the rare earth. As a result, the triangular block 7 will pass through the inclined plate 8 upward to scrape the rare earth on the triangular block 7 back into the smelting pool, and the stirring blade 3 will pass through the through hole of the rubber scraper 1101 to scrape the rare earth on the stirring blade 3 back into the smelting pool, avoiding the waste of rare earth resources. Subsequent workers only need to clean the small amount of residual rare earth at the bottom of the inclined plate 8 and the rubber scraper 1101, which is quick and convenient.

[0049] The additional technical effects of the present invention are as follows:

[0050] like Figure 4As shown, a counterweight block 1102 is installed on the side of the mounting frame 11 away from the inclined plate 8, which is used to balance the weight on both sides of the mounting frame 11 to avoid uneven weight at both ends of the mounting frame 11, which may cause the mounting frame 11 and the inclined plate 8 to deflect or even be driven upward when the stirring blade 3 passes through the through hole of the rubber scraper 1101, affecting the scraping of residual rare earth from the stirring blade 3 and the triangular block 7.

[0051] like Figure 4 As shown, the bottom of the triangular block 7 is tapered, which facilitates the insertion of the triangular block 7 downward into the rare earth.

[0052] like Figure 4 As shown, the conical bottom of the triangular block 7 is provided with a ball head. When a rubber liner is laid in the smelting pool, the conical bottom of the triangular block 7 is prevented from puncturing and damaging the rubber liner at the bottom of the smelting pool during the insertion of the rare earth into the bottom.

[0053] Example 2: Based on Example 1, Figure 2-Figure 4 As shown, it also includes an insertion rod 12, a support rod 13, a connecting rod 14 and an electric push rod 15; an insertion rod 12 is inserted into each movable roller 701; the bottom of each insertion rod 12 is fixedly connected to a limiting ball head 702; each limiting ball head 702 is fixedly connected to a stirring rod 1201; a support rod 13 is fixedly connected to the middle of the connecting block 6; the connecting rod 14 is rotatably connected to the support rod 13; both ends of the connecting rod 14 are rotatably connected to the top of a insertion rod 12; an electric push rod 15 is installed on the connecting block 6; the telescopic end of the electric push rod 15 is rotatably connected to one end of the connecting rod 14.

[0054] A production process of a stirring device for rare earth smelting and processing, comprising the following steps:

[0055] Step 1: Preparation of rare earth raw materials, crushing and grinding rare earth ore for subsequent smelting;

[0056] Step 2: Smelting and extraction: Place the processed rare earth raw materials into a smelting pool and add smelting chemical reagents;

[0057] Step 3: Stirring and mixing. The rare earth and chemical agents in the smelting pool are stirred and mixed by the stirring blade 3. During the stirring process, the triangular block 7 adheres to the side wall of the smelting pool, scrapes the rare earth on the side wall and guides it to the stirring blade 3 to participate in the stirring process.

[0058] Step 4: Collect the finished products, stir and mix them, and then take the smelted rare earth out of the smelting pool.

[0059] The operating steps of this embodiment are as follows:

[0060] When the triangular block 7 is in contact with the side wall of the smelting pool for scraping, the electric push rod 15 is controlled to repeatedly extend and retract, driving the connecting rod 14 to swing up and down with the connection with the support rod 13 as the fulcrum. The insertion rods 12 at both ends of the connecting rod 14 will move up and down alternately, and then the stirring rods 1201 at the bottom of each insertion rod 12 will swing up and down alternately. As the triangular block 7 moves, the rare earth near the bottom of the side wall of the smelting pool on the moving path is stirred, and the stirring blades 3 are cooperated to perform stirring work.

[0061] According to the above steps, we know that the present invention also has the following effects:

[0062] During the stirring process, there is a dead corner near the bottom of the smelting pool side wall. By swinging the stirring rod 1201 up and down, the rare earth near the bottom of the smelting pool side wall that is difficult for the stirring blade 3 to handle is stirred, thereby increasing the stirring effect and ensuring that the rare earth is fully stirred.

[0063] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
