[0023] Example 1

[0024] Embodiment 1 of the utility model is a precipitation treatment device for cerium nitrate processing, including a device body 1, the device body 1 is provided with a feed port 11 and a discharge port 12, and also includes a stirring mechanism 2 for stirring materials and clearing materials on the inner wall of the equipment body, the stirring mechanism 2 includes a rotating rod 21 connected to a first motor 20, a plurality of stirring rods 22 are provided on the periphery of the rotating rod 21 and are located inside the device body 1, a wall scraping assembly is provided on the outer peripheral surface of the rotating rod 21 located outside the device body 1, and the wall scraping assembly reciprocates in the device body 1.

[0025] In this embodiment, refer to Figures 1 to 3 After the cerium nitrate and the reaction liquid enter the device body 1 through the feed port 11, the stirring device is started, and the first motor 20 drives the rotating rod 21 to rotate, so that the stirring rod 22 stirs, so that the cerium nitrate and the reaction liquid in the device body 1 are fully mixed, the reaction rate is accelerated, and the reaction time is shortened. At the same time, the scraping assembly is connected to the rotating rod 21, and the rotating rod 21 rotates while the scraping assembly works, so that the scraping assembly moves up and down inside the device body 1 and is based on the inner wall of the device body 1, so that the sediment adhered to the inner wall is scraped off from top to bottom, and then collected at the bottom, to prevent the sediment in the inner wall from being scraped off completely and causing waste of resources.

[0026] In some preferred embodiments, the wall scraping assembly includes a first threaded rod 27 and a second threaded rod 28, the outer circumferential surface of the rotating rod 21 located outside the device body 1 is provided with a first main pulley 23 and a second main pulley 24 from top to bottom, the top of the first threaded rod 27 is provided with a first slave pulley 25, the top of the second threaded rod 28 is provided with a second slave pulley 26, and belts 36 are respectively arranged between the first slave pulley 25 and the first main pulley 23, the second slave pulley 26 and the second main pulley 24.

[0027] Reference Figure 1 The first threaded rod 27 is connected to the rotating rod 21 through the first main pulley 23, the first slave pulley 25 and the belt 36, and the second threaded rod 28 is connected to the rotating rod 21 through the second main pulley 24, the second slave pulley 26 and the belt 36. Therefore, during the rotation of the rotating rod 21, the first threaded rod 27 and the second threaded rod 28 are indirectly rotated, providing driving force for the first threaded rod 27 and the second threaded rod 28, so as to facilitate the subsequent scraping of the inner wall sediment.

[0028] In some preferred embodiments, a support seat 30 is symmetrically provided inside the device body 1, and the bottom end of the first threaded rod 27 and the bottom end of the second threaded rod 28 are respectively located in the support seat 30. A bearing 300 is provided in the support seat 30, and the bottom end of the first threaded rod 27 or the bottom end of the second threaded rod 28 is located in the bearing 300.

[0029] Specifically, the support seat 30 provides a receiving space for the installation of the first threaded rod 27 and the second threaded rod 28. At the same time, the surface of the support seat 30 is an inclined surface, which is conducive to the sediment scraped here to slide down to the middle of the device body 1 through the inclined surface, thereby preventing the sediment from accumulating on the surface of the support seat 30. The bearing 300 is located in the support seat 30, providing conditions for the rotation of the first threaded rod 27 and the second threaded rod 28. The first threaded rod 27 and the second threaded rod 28 pass through the top of the device body 1, and their bottom ends stop in the bearing 300, so that the first threaded rod 27 and the second threaded rod 28 can rotate.

[0030] In some preferred embodiments, first sliding blocks 32 are respectively provided on the outer peripheries of the first threaded rod 27 and the second threaded rod 28, and an annular plate 301 is symmetrically provided on the outside of the two first sliding blocks 32, the first sliding blocks 32 are connected to the inner wall of the annular plate 301, and the outer peripheral surface of the annular plate 301 is provided with a first scraper 302 that contacts the inner wall of the device body 1.

[0031] In this embodiment, the first threaded rod 27 and the second threaded rod 28 cause the first sliding block 32 to reciprocate on its outer periphery during the rotation process, and the annular plate 301 fixes the first sliding block 32 on its inner circumference. The first scraper 302 provided on the outer periphery of the annular plate 301 performs up and down scraping of the sediment, so that the sediment adhered to the device body 1 moves downward for collection, avoiding waste of resources, and the up and down scraping can scrape the sediment thoroughly.

[0032] Example 2

[0033] This embodiment 2 is implemented on the basis of embodiment 1, and a third threaded rod 29 driven by a second motor 31 and a filter screen 15 are provided below the support seat 30, and a second sliding block 33 is provided on the outer periphery of the third threaded rod 29, and a telescopic rod 34 is connected to the bottom of the second sliding block 33, and the telescopic end 341 of the telescopic rod 34 is connected to the second scraper 35, and the second scraper 35 is in contact with the surface of the filter screen 15.

[0034] Specifically, the precipitate mainly gathers above the filter 15, and the reaction liquid is distributed throughout the device body 1. During the stirring operation, the cerium nitrate only exists above the filter 15 for reaction. After the reaction is completed, the precipitate above the filter 15 needs to be discharged. At this time, the third threaded rod 29 will drive the second sliding drive telescopic rod 34 to reciprocate left and right. The bottom end of the telescopic rod 34 is connected to a second scraper 35. During the movement, the second scraper 35 scrapes the precipitate above the filter 15 to the discharge port, so that the precipitate in the filter 15 is completely collected.

[0036] Reference Figure 3 The purpose of the inclined placement of the filter screen 15 is to facilitate the discharge of the sediment above the filter screen 15 from the discharge port. At the same time, the telescopic rod 34 can adjust the telescopic height according to the height of the third threaded rod 29 and the surface of the filter screen 15, so that the second scraper 35 is always in contact with the filter screen 15, and the scraping effect is better played. Specifically, the telescopic end 341 is located in the sleeve 340 and is connected by a spring 342. The limit plate provided on the top of the telescopic end 341 effectively prevents the telescopic end 341 from being separated. When the telescopic rod 34 is at the rightmost end, the spring 342 is in a compressed state. When the telescopic rod 34 moves to the leftmost end, the telescopic end 341 of the telescopic rod 34 is under the elastic action, so that the second scraper 35 is always in contact with the filter screen 15, so that the sediment is scraped to the discharge port 12 during the movement.

[0037] It should be noted that the number of the third threaded rods 29 and the telescopic rods 34 is set according to actual conditions to ensure that the second scraper 35 can completely scrape off the sediment on the filter screen 15 .

[0039] With the partition plate 4 as the boundary, the bottom end of the device body 1 is a liquid collecting tank, and the filtered reaction liquid is transferred to the liquid collecting chamber 14 through the transition port 5 in the partition plate 4. Under the action of the pressure pump 18, the reaction liquid in the liquid collecting chamber 14 re-enters the device body 1 through the recovery pipe 16 and the liquid inlet 17 for reaction, thereby realizing the secondary utilization of the reaction liquid, allowing the unprecipitated cerium nitrate in the reaction liquid to fully react and avoiding waste of resources.

[0040] It should be noted that the external control component in this device is a prior art and will not be described in detail here.

[0041] When the utility model is used, the reaction liquid and the cerium nitrate rare earth enter the inside of the device body 1 through the feed port 11 in sequence, the reaction liquid is located above the partition plate 4, the cerium nitrate rare earth is located above the filter screen 15, the stirring mechanism 2 is started, the stirring rod 22 makes the cerium nitrate rare earth and the reaction liquid fully mixed, and at the same time, the rotating rod 21 rotates the first threaded rod 27 and the second threaded rod 28 through the main pulley and the slave pulley, so that the first sliding block 32 drives the first scraper 302 in the annular plate 301 to scrape up and down on the inner wall of the device body 1, and the second sliding block 33 drives the second scraper 35 connected to the telescopic rod 34 to scrape left and right on the surface of the filter screen 15 under the action of the third threaded rod 29, effectively accelerating the reaction rate, shortening the reaction time, and effectively scraping the sediment on the inner wall of the device body 1 and the filter screen 15, avoiding the waste caused by the accumulation of sediment. The liquid collecting chamber 14 can re-enter the reaction liquid that has not precipitated cerium nitrate into the device body 1 through the pressure pump 18 to participate in the reaction again, so that the cerium nitrate is completely reacted and resources are saved.
