Abstract
Description
Technical Field
[0001] This utility model relates to a purification device, specifically a purification device for lithium adsorbents. Background Technology
[0002] Lithium adsorbent particles are functional materials that selectively adsorb lithium ions in brine and are an important component in the lithium extraction process from salt lakes. In the adsorption stage of the lithium extraction process (including adsorption, top feeding, rinsing, and desorption), the performance of the adsorbent is a key factor determining critical parameters such as adsorption capacity, rinsing water consumption, and desorption rate.
[0003] After lithium adsorbent particles are produced, they usually need to undergo further purification to remove impurities and improve their purity.
[0004] However, existing filtration structures can only filter out impurities of the same size from lithium adsorbent particles. In this case, smaller impurities will still exist in the adsorbent particles, resulting in poor purity of the lithium adsorbent particles. Utility Model Content
[0005] The main objective of this invention is to provide a lithium adsorbent purification device to solve the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides a lithium adsorbent purification device, including a cylinder, a filter assembly, and a collection frame;
[0007] The cylinder is equipped with a rotatable spiral conveyor blade, a discharge port is provided on the lower left side of the cylinder, a feed hopper is provided on the upper right side of the cylinder, and a first opening and a second opening are provided on the lower end of the cylinder.
[0008] The filter assembly is located at the lower end of the cylinder. The filter assembly includes a first filter plate and a second filter plate. The first filter plate is located in a first opening, and the second filter plate is located in a second opening. The diameter of the filter holes on the first filter plate is larger than that on the second filter plate.
[0009] The collecting frame is located on the lower left side of the cylinder, and the upper end of the collecting frame is provided with a feeding channel, which corresponds to the discharge port.
[0010] The aforementioned beneficial effects are as follows: when lithium adsorbent particles are added to the feed hopper, the adsorbent particles continuously fall into the cylinder. At this time, the rotating screw conveyor continuously agitates and conveys the adsorbent particles towards the discharge port. Larger impurities in the adsorbent particles fall through the filter holes on the first filter plate, while smaller impurities fall through the filter holes on the second filter plate. The adsorbent particles then fall from the discharge port through the feed channel into the collection frame for collection. Thus, impurities of different sizes in the lithium adsorbent particles are removed, thereby improving the purity of the lithium adsorbent particles.
[0011] In a preferred embodiment, a temporary storage frame is provided on the lower side of the cylinder, the temporary storage frame having a first receiving portion and a second receiving portion, the first receiving portion being located on the lower side of the first filter plate, and the second receiving portion being located on the lower side of the second filter plate.
[0012] A preferred embodiment is that the cylinder is provided with a movable annular ring, and the lower inner wall of the annular ring is provided with hard bristles, which are arc-shaped.
[0013] In a preferred embodiment, a telescopic rod is provided at the lower end of the feed hopper, and a spring structure is sleeved on the outer end of the telescopic rod. The outer end of the telescopic rod cooperates with a cam, and the cam is connected to a motor.
[0014] A preferred embodiment is that the cylinder has support frames at both ends. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] like Figures 1 to 4 This utility model provides a lithium adsorbent purification device, including a cylinder 10, a filter assembly 20 and a collection frame 30;
[0023] The cylinder 10 is provided with a rotatable spiral conveyor plate 11. The lower left side of the cylinder 10 is provided with a discharge port 12. The upper right side of the cylinder 10 is provided with a feed hopper 13. The lower end of the cylinder 10 is provided with a first opening 14 and a second opening 15.
[0024] The filter assembly 20 is disposed at the lower end of the cylinder 10. The filter assembly 20 includes a first filter plate 21 and a second filter plate 22. The first filter plate 21 is disposed in the first opening 14, and the second filter plate 22 is disposed in the second opening 15. The diameter of the filter holes on the first filter plate 21 is larger than that on the second filter plate 22.
[0025] The collection frame 30 is located on the lower left side of the cylinder 10, and the upper end of the collection frame 30 is provided with a feeding channel 31, which corresponds to the discharge port 12.
[0026] During operation, lithium adsorbent particles are added to the feed hopper 13, and the particles continuously fall into the cylinder 10. At this time, the spiral conveyor 11 rotates, continuously stirring and conveying the adsorbent particles towards the discharge port 12. Larger impurities in the adsorbent particles fall through the filter holes on the first filter plate 21, while smaller impurities fall through the filter holes on the second filter plate 22. The adsorbent particles then fall from the discharge port 12 through the feed channel 31 into the collection frame 30 for collection. This process removes impurities of different sizes from the lithium adsorbent particles, thereby improving their purity.
[0027] Preferably, a temporary storage frame 40 is provided on the lower side of the cylinder 10. The temporary storage frame 40 has a first receiving part 41 and a second receiving part 42. The first receiving part 41 is provided on the lower side of the first filter plate 21, and the second receiving part 42 is provided on the lower side of the second filter plate 22.
[0028] Larger impurities fall into the first receiving section 41 for temporary storage, while smaller impurities fall into the second receiving section 42 for temporary storage. These impurities will then be processed uniformly in the future.
[0029] Preferably, a movable annular ring 50 is provided on the upper part of the cylinder 10, and hard bristles are provided on the lower inner wall of the annular ring 50, wherein the hard bristles are arc-shaped.
[0030] When it is necessary to clean the impurities in the filter holes on the first filter plate 21 and the second filter plate 22, the personnel can move the annular ring 50, and the hard bristles can move from the first filter plate 21 to the second filter plate 22, or from the second filter plate 22 to the first filter plate 21. This is to clean the impurities in the filter holes by the action of the hard bristles, so as to avoid affecting the filtration quality and efficiency of the lithium adsorbent particles.
[0031] Preferably, the lower end of the feed hopper 13 is provided with a telescopic rod 60, the outer end of the telescopic rod 60 is fitted with a spring structure 61, the outer end of the telescopic rod 60 cooperates with a cam 62, and the cam 62 is connected to a motor.
[0032] When adsorbent particles clog the feed inlet at the lower end of the feed hopper 13, personnel can drive the cam 62 to rotate via a motor. The cam 62 continuously contacts the telescopic rod 60, causing the spring structure 61 to extend and retract. The telescopic rod 60 continuously stirs the adsorbent particles in the feed hopper 13, clearing the feed inlet and thus preventing blockage.
[0033] Preferably, the two ends of the cylinder 10 are respectively provided with support frames 5.
[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
