Description

TECHNICAL FIELD

[0001] The present application relates to the field of purification and separation technology, and particularly relates to a fluorine-based resource purification device and a purification method. BACKGROUND

[0002] In the field of fluorine-based resource (such as calcium fluoride, hydrofluoric acid, etc.) processing and treatment, the purification of fluorine-containing resource solution (specifically, fluorite-containing calcium crystal particle solution) is a key link. The core requirement is to achieve efficient solid-liquid separation while ensuring operation safety and resource recovery quality. Currently, the fluorine-based resource purification devices commonly used in the industry rely on traditional filter structures to complete the solid-liquid separation operation.

[0003] For example, the patent "CN221084810U A kind of extraction separation equipment for calcium fluoride production" discloses a technical solution for separating calcium fluoride from solution, and provides a method for quickly cleaning the filter screen after the solid-liquid separation operation is completed. However, in actual production process, calcium fluoride crystal particles not only easily adhere to the surface of the filter screen but also deeply accumulate in the pores. The current cleaning method is difficult to reach the particles accumulated in the pores, and it is also difficult to clean the filter structure in real time during the purification process. Finally, the existing fluorine-based resource purification device mainly uses indirect methods such as flow statistics and liquid level estimation to monitor the weight of fluorine-based resources in the separation component, which is easily disturbed by external factors such as solution flow speed and uniformity, and has low monitoring accuracy. It is difficult for workers to accurately judge the bearing state of the separation component, which may cause component damage due to overload operation, or may not be able to find filter cartridge damage in time due to monitoring data deviation, resulting in fluorine-based resource leakage and waste. With the improvement of the industry's requirements for fluorine-based resource purification quality, some scenes need to purify fluorine-based resources twice. However, the existing devices generally lack corresponding functional design and cannot meet the purification operation requirements of different purity, so the scene adaptation range is limited.

[0023] As shown in Figure 2 , Figures 6-7 , the transmission assembly includes two liquid inlet pipes 17 and a transmission seat 18, the two liquid inlet pipes 17 are oppositely arranged at both ends of the transmission seat 18 and both extend out of the tank body 1, the transmission seat 18 is provided with a gear 181 and a rack 182, the gear 181 is connected with the first linkage seat 1323 through a rotating shaft, the rack 182 is engaged with the gear 181, and both ends of the rack 182 are arranged inside the two liquid inlet pipes 17, respectively, in the working process of the application, the ends of the two liquid inlet pipes 17 away from the transmission seat 18 are respectively connected with external driving medium conveying equipment, when the staff needs to rotate the first filter cartridge 162 and the second filter cartridge 163 in the separation assembly 16 around the axis of the positioning cylinder 161, driving medium can be injected into one of the liquid inlet pipes 17 through the driving medium conveying equipment, at this time, the driving medium will generate a thrust force on one end of the rack 182, pushing the rack 182 to move in the direction of the other liquid inlet pipe 17, while the driving medium is injected from the other liquid inlet pipe 17, the rack 182 is pushed to move in the opposite direction, so as to realize the reciprocating linear motion of the rack 182 in the two liquid inlet pipes 17, finally, since the rack 182 is engaged with the gear 181, the reciprocating linear motion of the rack 182 can drive the gear 181 to periodically rotate in the opposite direction around the rotating shaft, and then drive the first filter cartridge 162 and the second filter cartridge 163 to rotate around the axis of the positioning cylinder 161, through the above technical solution, the application reduces the participation of the electrical elements at the bottom of the tank body 1, prevents the probability of failure of the electrical elements in the long-term running process, and avoids the influence of the separated liquid on the service life of the transmission assembly.

The two movable plates 142 are connected through two double-headed cylinders 143, and the ends of the two movable plates 142 close to each other are provided with second teeth. The double-headed cylinder 143 is used to synchronously drive the two movable plates 142 to move close to or away from each other through the extension and retraction action. When it is necessary to fix the position of the positioning cylinder 161, the double-headed cylinder 143 is used to drive the two movable plates 142 to move towards the positioning cylinder 161 until the two movable plates 142 clamp the outer wall of the positioning cylinder 161.

[0026] As shown in Figure 8As shown, each movable plate 142 is provided with a filter plate 1421, and the second teeth on the two movable plates 142 are adapted to each other. When the second teeth on the two movable plates 142 are engaged, the engagement surfaces are tightly fitted without any gap therebetween. When the fluorine-based resource solution is separated by the solid-liquid separation, if the worker needs to purify the fluorine-based resource again, the worker can first drive the two movable plates 142 away from the positioning cylinder 161 by the double-headed air cylinder 143, then control the carrier 133 to descend by the lifting motor 141 and the lead screw assembly 131, at this time, the separation assembly 16 will descend synchronously under the action of its own gravity and the gravity of the fluorine-based resource inside, when the upper surface of the positioning cylinder 161 is flush with the lower surfaces of the two movable plates 142, the lifting motor 141 and the lead screw assembly 131 control the carrier 133 to stop descending, and finally the two movable plates 142 are folded above the positioning cylinder 161 by the double-headed air cylinder 143, at this time, the worker can introduce clean water into the third interface 15 to flush the fluorine-based resource in the separation assembly 16 in the reverse direction (the filter plate 1421 on each movable plate 142 plays a blocking role), after the reverse flushing is completed, the worker can drive the two movable plates 142 away from the positioning cylinder 161 by the double-headed air cylinder 143, and then control the carrier 133 to ascend by the lifting motor 141 and the lead screw assembly 131, so that the worker can take out the fluorine-based resource in the separation assembly 16.

[0027] As shown in Figures 2-3 The distance between the upper surface of the positioning cylinder 161 and the lower surfaces of the two movable plates 142 is less than the up-down movement stroke of the linkage assembly, and the distance between the upper surface of the positioning cylinder 161 and the lower surfaces of the two movable plates 142 is less than the detection stroke of the measurement assembly. Through the above technical solution, it is ensured that the linkage assembly and the measurement assembly will not hinder the descent of the separation assembly 16 when the worker flushes the fluorine-based resource in the separation assembly 16 in the reverse direction.

[0028] A purification method used on a fluorine-based resource purification device, comprising the following steps: S1: sending a fluorine-based resource solution from the first interface 11 into the tank 1; S2: separating the fluorine-based resource solution by the separation assembly 16, and the separated liquid is discharged from the tank 1 through the third interface 15; S3: after the solid-liquid separation is completed, the worker can open the sealing cover 12, and then control the separation assembly 16 to ascend by the lifting motor 141, so that the worker can take away the fluorine-based resource in the separation assembly 16.

[0029] The working principle of the present application is as follows: during the purification operation, the fluorine-based resource solution enters the tank body 1 through the first interface 11, then flows into the separation assembly 16 along the fixed seat 14, and the solid-liquid separation of the fluorine-based resource solution is carried out through the first filter cylinder 162 and the second filter cylinder 163 in the separation assembly 16, wherein the separated liquid is discharged from the tank body 1 through the third interface 15; during the solid-liquid separation operation, the worker can convey high-pressure water flow into the second interface 121 as needed, at this time the high-pressure water flow enters the isolation frame 164 through the hose, and the high-pressure water flow is guided through the isolation frame 164 to flush the filter holes on the first filter cylinder 162 and the second filter cylinder 163, so as to avoid the accumulation of impurities in the filter holes; in this process, the worker can also inject the driving medium into the transmission assembly through the driving medium conveying equipment, so that the transmission assembly rotates around the axis of the positioning cylinder 161 with the first filter cylinder 162 and the second filter cylinder 163, thereby further improving the cleanliness of the entire separation assembly 16; when the solid-liquid separation of the fluorine-based resource solution is completed, if the worker needs secondary purification, the worker can first drive the two movable plates 142 away from the positioning cylinder 161 through the double-head cylinder 143, then control the bearing frame 133 to descend through the lifting motor 141 and the screw assembly 131, at this time the separation assembly 16 will descend synchronously under the action of its own gravity and the gravity of the fluorine-based resources inside, when the upper surface of the positioning cylinder 161 is flush with the lower surface of the two movable plates 142, the lifting motor 141 and the screw assembly 131 control the bearing frame 133 to stop descending, and finally the two movable plates 142 are driven to fold above the positioning cylinder 161 through the double-head cylinder 143, at this time the worker can pass clean water into the third interface 15 to reverse flush the fluorine-based resources in the separation assembly 16, after the reverse flushing is completed, the worker can drive the two movable plates 142 away from the positioning cylinder 161 through the double-head cylinder 143, and then control the bearing frame 133 to rise through the lifting motor 141 and the screw assembly 131, so that the worker can take out the fluorine-based resources in the separation assembly 16.
