[0002] The rare earth chloride salt solution filtration device is a key piece of equipment in the rare earth hydrometallurgical process. It is mainly used to remove solid impurities (including undissolved rare earth oxides, mechanical particles, crystalline salts, etc.) from rare earth chloride salt solutions (such as LaCl3, NdCl3, etc.) to obtain a high-purity solution, providing high-quality raw materials for subsequent rare earth separation and purification, material preparation and other processes.

[0003] When existing rare earth chloride salt solutions enter the filtration chamber, they tend to generate concentrated impact force, causing the solution to mainly rush towards local areas of the filter screen. Due to the continuous impact of high flow rate and high impurity concentration, the filter screen in these local areas rapidly accumulates filter cake or crystals, causing local blockage. Meanwhile, other areas of the filter screen are not fully utilized, resulting in reduced filtration efficiency. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: a rare earth chloride salt solution filtration device, including a filter assembly 1, a flow guiding assembly 2 on the top of the filter assembly 1, a cleaning assembly 3 on the side of the filter assembly 1, and an installation / removal assembly 4 inside the filter assembly 1. The filter assembly 1 includes a filter tank 101, and a filter frame 102 is provided inside the filter tank 101. The flow guiding assembly 2 includes a feed tank 201, a conical flow guiding plate 202 connected to the bottom of the feed tank 201, and a support frame 2 connected inside the feed tank 201. 03. A connecting ring 204 is connected to the bottom of the support frame 203, and a rotating motor 205 is connected to the bottom of the connecting ring 204. A vibration motor 103 is installed on the side of the filter barrel 101. Multiple buffer dampers 104 are distributed at the bottom of the filter barrel 101. A support base 105 is provided at the bottom of the buffer damper 104. The storage box 301 is set on the support base 105. A discharge pipe 106 is connected to the bottom of the filter barrel 101. A valve is provided on the discharge pipe 106. The rotating motor 205 is located on the side of the filter barrel 101.

[0027] In this embodiment, by pouring the rare earth chloride solution into the feed tank 201, the solution is facilitated to flow into the filter tank 101 through the guide grooves on the conical guide plate 202. This facilitates the flow of the rare earth chloride solution, reduces local accumulation, and minimizes filter screen blockage due to overload, effectively improving filtration efficiency. Simultaneously, the vibration generated by the vibration motor 103 further enhances the uniformity of the rare earth chloride solution distribution within the filter tank 101, further improving filtration efficiency. The buffer damper 104 helps absorb some of the high-frequency vibration energy of the vibration motor 103, reducing the transmission to other components. The rotating motor 205 drives the connecting ring 204 to rotate, which in turn helps the support frame 203 to drive the feed tank 201 and the conical guide plate 202 to rotate. This allows the feed tank 201 and the conical guide plate 202 to move to the side without affecting the normal installation, disassembly and maintenance of the filter frame 102. The filter frame 102 has multiple filter screens inside, which helps to filter the rare earth chloride salt solution step by step, improving the filtration efficiency.

[0028] Example 2: Figures 1-5As shown, the installation and removal assembly 4 includes a limiting ring 401, which is fixedly installed inside the filter barrel 101. The bottom of the filter frame 102 is connected to the limiting ring 401. A pressure ring 402 is provided inside the filter barrel 101. A locking component 403 is symmetrically installed on the top of the pressure ring 402. A fastening bolt 404 passes through the inside of the locking component 403. The bottom of the fastening bolt 404 is located on the filter barrel 101. The cleaning assembly 3 includes a storage box 301. A pump 302 is provided on the top of the storage box 301. A delivery pipe 304 is connected to the top of the pump 302. One end of the delivery pipe 304 is connected to a spray ring 303. Multiple high-pressure nozzles 305 are symmetrically distributed on the inner side of the spray ring 303. The spray ring 303 is located on the filter barrel 101, and the high-pressure nozzles 305 are located inside the filter barrel 101.

[0029] In this embodiment, by moving the flow guide assembly 2 to the side, the filter frame 102 is then installed inside the filter barrel 101. The limiting ring 401 provides a bottom limiting effect for the filter frame 102. Then, the clamping part 403 is used to abut against the top of the filter frame 102, and the fastening bolt 404 is threaded into the clamping part 403. This provides a limiting effect for the pressure ring 402, facilitating the installation and removal of the filter frame 102. This also facilitates the maintenance and cleaning of the filter frame 102. The filter frame 102 is removed from the inside of the filter barrel 101, and the cleaning agent inside the storage tank 301 is drawn out by the pump 302 and transported to the inside of the spray ring 303 through the delivery pipe 304. It is then sprayed out through the high-pressure nozzle 305, which helps to achieve preliminary cleaning of the inside of the filter barrel 101 and reduces the cost and labor cost of subsequent fine cleaning.

[0030] The working principle of this embodiment is as follows: In use, the rare earth chloride solution is first poured into the feed tank 201. This facilitates the flow of the solution through the guide grooves on the conical guide plate 202 into the filter tank 101, promoting efficient flow. Simultaneously, the vibration motor 103 generates vibration, improving the uniformity of the solution's distribution within the filter tank 101 and further enhancing filtration efficiency. The buffer damper 104 absorbs some of the high-frequency vibration energy from the motor 103. The filter frame 102 has multiple filter stages, enabling step-by-step filtration of the rare earth chloride solution. When maintenance is required, the connecting ring 204 is rotated by the motor 205, which in turn causes the support frame 203 to move the feed tank 201 and the conical guide plate. Rotating 202 facilitates the movement of the feed hopper 201 and the conical guide plate 202 to the side. The filter frame 102 is then installed inside the filter hopper 101. The limiting ring 401 provides bottom limiting for the filter frame 102. A clamping component 403 is then used to abut against the top of the filter frame 102, and a fastening bolt 404 is threaded into the clamping component 403. This provides limiting for the pressure ring 402, facilitating the installation and removal of the filter frame 102, and consequently, its maintenance and cleaning. The filter frame 102 is removed from the filter hopper 101, and the cleaning agent inside the storage tank 301 is drawn by the pump 302 and transported through the delivery pipe 304 to the spray ring 303. It is then sprayed out through the high-pressure nozzle 305, achieving initial cleaning of the filter hopper 101 and reducing subsequent fine cleaning costs and labor costs.

The appropriate model is selected according to actual use. Therefore, the vibration motor 103, buffer damper 104, rotary motor 205, and pump 302 will not be explained in detail.
