Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a rare earth chloride solution storage tank. Background Art

[0002] Rare earth chloride is an industrial raw material used as a raw material for electrolysis of mixed rare earth metals, rare earth alloys and extraction of single rare earth elements. It can also be used as a raw material for petrochemical catalysts, co-catalysts and rare earth polishing powders. For example, the Chinese invention patent with patent number "CN202310592554.4" and patent name "A preparation system and process for preparing rare earth chloride using monazite ore" discloses a method for preparing rare earth chloride, wherein the monazite ore is subjected to a series of alkaline washing and acid washing processes to obtain a rare earth chloride solution, and finally rare earth chloride crystals are obtained by evaporation and crystallization. In the process of the rare earth chloride solution waiting for evaporation and crystallization, the rare earth chloride solution that has completed the previous process needs to be placed in a storage tank for storage, but there is still a small amount of slag residue in the rare earth chloride solution in the storage tank, which will settle in the storage tank. If not treated, it will affect the quality of the subsequent evaporation and crystallization; if the slag-containing rare earth chloride turbid liquid at the bottom is first discharged, it will need to be stored in a container again for sedimentation, which increases the complexity of the process. Utility Model Content

[0003] In order to solve the technical problem that a small amount of slag settles in the existing rare earth chloride solution and affects the quality of the later rare earth chloride crystallization, the utility model provides a rare earth chloride solution storage tank.

[0004] The technical solution of the utility model is realized through the following scheme: a rare earth chloride solution storage tank comprises a tank body, a feed port, a discharge port and a sediment port, wherein the upper part of the tank body is provided with a feed port; the lower part of the tank body is provided with a sediment port, and the tank body above the sediment port is provided with a discharge port; a rotating partition mechanism is rotatably installed in the tank body between the sediment port and the discharge port, a rotating drive mechanism is installed on the top of the tank body, and the rotating drive mechanism is connected to the rotating partition mechanism to drive the rotating partition mechanism to rotate.

[0005] By using the above technical scheme, a rotating baffle mechanism is added to the storage tank, and the rotating baffle mechanism separates the clear rare earth chloride solution and the turbid rare earth chloride solution in the tank body. When the rare earth chloride solution has been precipitated, the rotating baffle mechanism divides the tank body into two, and the clear liquid on the upper side flows out from the discharge port for evaporation and crystallization, and the turbid liquid on the lower layer can be selected to be released, or the slag can be accumulated and cleaned after multiple storage and sedimentation, thereby ensuring the quality of rare earth chloride crystallization and solving the problem of frequent cleaning of a small amount of settled slag.

[0006] Preferably, the rotating partition mechanism includes a partition mounting frame and several groups of rotating partitions arranged in a stacked manner, the partition mounting frame is fixedly mounted on the inner cavity side wall of the tank body; the rotating partitions are rotatably connected to the partition mounting frame, and the bottommost rotating partitions are fixedly connected to the inner cavity side wall of the tank body; the topmost rotating partitions are fixedly connected to the output end of the rotating driving mechanism, and the upper and lower adjacent rotating partitions are slidably connected.

[0007] By using the above technical solution, several groups of rotating baffles are rotatably connected to form relatively closed upper and lower cavities in the tank body, so that when the clear liquid of the rare earth chloride solution flows out, it will not stir the slag below the cavity to flow out, so that the slag can be processed together after multiple sedimentation and accumulation, while ensuring the quality of evaporation and crystallization, reducing labor intensity and process complexity.

[0008] Preferably, the rotating partition includes a fan-shaped plate, a hinge hole, a sliding groove and a connecting column. A hinge hole is provided on the center side of the fan-shaped plate, and the fan-shaped plate is hingedly connected to the partition mounting frame through the hinge hole. A sliding groove is provided on the arc side of the fan-shaped plate, and a connecting column is fixedly installed on the lower part of the fan-shaped plate. The connecting column of the upper fan-shaped plate is slidably connected to the sliding groove of the lower fan-shaped plate.

[0009] Preferably, the number of the fan-shaped plates is not less than 6 groups.

[0010] By using the above technical solution, the hinged installation of the rotating partition and the structural connection mode of the sliding groove enable the rotating partition to open and close to form a full circle, thereby separating the upper and lower cavities of the tank body to avoid the outflow of turbid liquid containing slag when the clear liquid flows out. No less than 6 groups of fan-shaped plates can reduce the settlement of slag on the area of ​​the uppermost fan-shaped plate as much as possible to minimize the impact of slag on the clear liquid.

[0011] Preferably, the rotary drive mechanism comprises a rotary motor and a rotary shaft, wherein the rotary motor is fixedly mounted on the top of the tank body, the output end of the rotary motor is connected to the rotary shaft, and the rotary shaft is located inside the tank body; one end of the rotary shaft is fixedly connected to the topmost rotary partition.

[0012] Preferably, a sealing ring is further provided on the inner cavity side wall of the tank body, and the outer arc side of the rotating partition is embedded and connected to the sealing ring; the rotating partition can slide relative to the sealing ring.

[0013] By using the above technical solution, the upper structure setting of the rotating drive mechanism can reduce the disturbance to the bottom of the solution, thereby preventing the sedimentation of the slag in the bottom layer from being stirred. The setting of the sealing ring can effectively seal the sliding groove opened on the fan-shaped plate, and when the upper clear liquid flows out, the turbid liquid in the lower layer is prevented from flowing out of the sliding groove.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The utility model provides a rare earth chloride solution storage tank in which a rotating baffle mechanism is added. The rotating baffle mechanism separates the rare earth chloride solution clear liquid and the rare earth chloride solution turbid liquid on the tank body. When the rare earth chloride solution has been settled, the rotating baffle mechanism divides the tank body into two. The upper clear liquid flows out from the discharge port for evaporation and crystallization, and the lower turbid liquid can be selectively discharged, or the slag can be accumulated and cleaned after multiple storage and sedimentation, thereby ensuring the quality of rare earth chloride crystallization and solving the problem of frequent cleaning of a small amount of settled slag.

[0016] 2. Furthermore, several groups of rotating baffles are rotatably connected to form relatively closed upper and lower cavities in the tank body, so that when the clear liquid of the rare earth chloride solution flows out, it will not stir the slag below the cavity to flow out, so that the slag can be processed together after multiple sedimentation and accumulation, while ensuring the quality of evaporation and crystallization, reducing labor intensity and process complexity.

[0017] 3. The hinged installation of the rotating partition and the structural connection with the sliding groove enable the rotating partition to open and close to form a full circle, thereby separating the upper and lower cavities of the tank body to prevent the outflow of turbid liquid containing slag when the clear liquid flows out. No less than 6 groups of fan-shaped plates can reduce the settlement of slag on the area of ​​the uppermost fan-shaped plate as much as possible to minimize the impact of slag on the clear liquid.

[0018] 4. Furthermore, the upper structure of the rotary drive mechanism can reduce the disturbance to the bottom of the solution, thereby preventing the bottom slag from settling and stirring. The blocking ring can effectively block the sliding groove on the fan-shaped plate, and when the upper clear liquid flows out, the lower turbid liquid is prevented from flowing out of the sliding groove.

[0025] In the following description, many specific details are set forth to facilitate 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 of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] The utility model provides a rare earth chloride solution storage tank, such as Figure 1-Figure 4 As shown, the tank body 1 comprises a tank body 1, a feed port 2, a discharge port 3 and a sediment port 4. The tank body 1 is used as a storage tank body for the rare earth chloride solution and is a circular barrel-shaped structure. The upper part of the tank body 1 is provided with a feed port 2. The rare earth chloride solution completed through the previous process is fed into the tank body 1 through the feed port 2 for storage. The lower part of the tank body 1 is provided with a sediment port 4. The sediment port 4 is used to regularly clean the slag settled at the bottom of the tank body 1. The tank body 1 above the sediment port 4 is provided with a discharge port 3; the discharge port 3 is opened on the tank body of the side of the tank body 1 to flow out the rare earth chloride solution into the evaporation crystallization process; in the sedimentation process, the discharge port 3 is provided ... A rotating baffle mechanism 5 is rotatably installed in the tank body 1 between the slag outlet 4 and the discharge port 3. The rotating baffle mechanism 5 serves as a partition mechanism of the inner cavity of the tank body 1, and isolates the rare earth chloride solution after the slag is settled at the lower part and the rare earth chloride solution at the upper part, so that the upper clear liquid flows out from the discharge port 3 without causing disturbance when the upper clear liquid flows out, causing the slag at the lower part to flow out; a rotating drive mechanism 6 is installed on the top of the tank body 1, as a power drive mechanism of the rotating baffle mechanism 5, and the rotating drive mechanism 6 is connected to the rotating baffle mechanism 5 to drive the rotating baffle mechanism 5 to rotate.

[0028] As one of the specific embodiments, the rotating partition mechanism 5 includes a partition mounting frame 51 and several groups of rotating partitions 52 arranged in a stacked manner. The partition mounting frame 51 serves as a supporting mounting frame for supporting the rotating partition 52 to rotate along the axial direction, and is fixedly mounted on the inner cavity side wall of the tank body 1. The outer arc side of the rotating partition 52 is fitted and mounted on the inner cavity side wall of the tank body 1. The rotating partition 52 is rotatably connected to the partition mounting frame 51, and the bottom rotating partition 52 is fixedly connected to the inner cavity side wall of the tank body 1; the top rotating partition 52 is fixedly connected to the output end of the rotating drive mechanism 6, and the upper and lower adjacent rotating partitions 52 are slidably connected. The number of rotating partitions 52 is not less than 6 groups. The 6 groups of rotating partitions 52 can form a relatively closed circular plate after rotation, and the upper and lower adjacent rotating partitions 52 that have completed rotation overlap to avoid obstruction during the unscrewing process, resulting in an inability to open and close.

[0029] Specifically, a single set of rotating partitions 52 includes a fan-shaped plate 521, a hinge hole 522, a sliding groove 523 and a connecting column 524. A hinge hole 522 is provided on the center side of the fan-shaped plate 521, and the fan-shaped plate 521 is hingedly connected to the partition mounting frame 51 through the hinge hole 522. A sliding groove 523 is provided on the arc side of the fan-shaped plate 521. Adjacent rotating partitions 52 are slidingly connected through the sliding groove 523 and the connecting column 524. When the upper rotating partition 52 rotates, the connecting column 524 of the upper fan-shaped plate 521 slides in the sliding groove 523 of the lower rotating partition 52. When it slides to one end, it drives the next fan-shaped plate 521 to continue to rotate and slide, so that multiple rotating partitions 52 finally form a relatively closed circular plate, which divides the tank body 1 into an upper cavity and a lower cavity.

[0030] The rotating drive mechanism 6 includes a rotating motor 61 and a rotating shaft 62. The rotating motor 61 is fixedly installed on the top of the tank body 1 as a power mechanism. The output end of the rotating motor 61 is connected to the rotating shaft 62, and the rotating shaft 62 is located inside the tank body 1; one end of the rotating shaft 62 is fixedly connected to the topmost rotating partition 52, and the rotating shaft 62 drives the topmost rotating partition 52 to rotate, thereby driving the rotating partition 52 below to rotate, and finally forming a relatively closed circular structure.

[0031] A sealing ring 7 is also provided on the inner cavity side wall of the tank body 1. The sealing ring 7 serves as a sliding groove mechanism between the outer arc side of the rotating baffle 52 and the inner cavity of the tank body 1. The sealing ring 7 includes two layers of annular plates spaced apart from each other and fixedly installed on the inner cavity side wall of the tank body 1. The upper and lower layers of annular plates constitute a groove structure for the sliding movement of the rotating baffle 52. The outer arc side of the lowest rotating baffle 52 is arranged above the lower sealing ring 7, and the uppermost rotating baffle 52 is located below the upper sealing ring 7. On the one hand, it is used to form support for the outer arc sides of several rotating baffles 52, and on the other hand, it can seal the connecting part of the sliding groove 523 between the upper and lower cavities in the tank body 1.

[0032] The working principle of the utility model is as follows: when liquid is being stored, the rotary drive mechanism 6 is controlled to fold the rotary baffle 52 to avoid damage to the rotary baffle mechanism 5 caused by impact of the solution, and the solution is precipitated in the folded state of the rotary baffle mechanism 5. After the solution is precipitated, the rotary baffle mechanism 5 is closed, and the rotary drive mechanism 6 drives the uppermost fan-shaped plate 521 to rotate. When the uppermost fan-shaped plate 521 rotates to a certain distance, it is connected to the fan-shaped plate 521 of the lower layer through the sliding groove 523, thereby driving the fan-shaped plate 521 of the lower layer to rotate with the fan-shaped plate 521 of the upper layer, and then in this way, until all the fan-shaped plates 521 are rotated and closed to form a circular structure. After it is completely closed, the clear liquid of the upper rare earth chloride solution flows out through the discharge port 3, and then the storage and sedimentation are repeated once more. When the slag located below the rotary baffle mechanism 5 is settled for many times, it is cleaned together.

[0033] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
