Description

Technical Field

[0001] This utility model relates to the field of purification technology, and in particular to a device for refining and purifying perfluorosulfonic acid resin. Background Technology

[0002] Perfluorosulfonic acid resin is a polymer material with advantages such as good heat resistance, excellent chemical stability, high mechanical strength, and good hot melt processability, and it has wide applications in modern industry. In the refining and purification of perfluorosulfonic acid resin, extraction purification equipment is widely used. The perfluorosulfonic acid resin is dispersed in a mixed solvent, and an extractant is added for extraction. The extractant is brought into full contact with the dispersion by stirring or ultrasound. After standing, a two-phase liquid is formed, and then the two liquids are extracted and discharged separately.

[0003] In existing extraction and purification devices, a suction tube is used to draw in the upper, lighter liquid, while a discharge tube is used to discharge the lower, heavier liquid. However, although the suction tube used to draw in the upper, lighter liquid can be height-adjusted, this adjustment is done manually and secured with screws. This manual adjustment is prone to significant errors, which in turn affect the effective separation of the two liquids, resulting in generally poor performance. Utility Model Content

[0004] The main objective of this invention is to provide a device for refining and purifying perfluorosulfonic acid resin, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] Compared with the prior art, this utility model has the following beneficial effects: This perfluorosulfonic acid resin refining and purification device, through the upper light liquid extraction structure, uses a servo motor, lead screw, and other structures to adjust the height of the mounting components, thereby moving the lifting suction tube. Combined with an ultrasonic interface sensor, it ensures that the end of the lifting suction tube is close to the interface between the two liquids after extraction and purification, ensuring suction accuracy and avoiding large errors.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a perfluorosulfonic acid resin refining and purification apparatus includes a purification tank 1. The upper end of the purification tank 1 is provided with a top cover 2, and the top cover 2 has a feed inlet 3. A bracket 4 is installed on the top cover 2, and a stirring motor 5 is fixed on the bracket 4. A stirring rack 6 is provided inside the purification tank 1. An ultrasonic interface sensor 7 is installed on the top cover 2 and located inside the purification tank 1. The top cover 2 is provided with an upper light liquid extraction structure 8. A drain pipe 9 is provided at the lower end of the purification tank 1, and a support leg 12 is installed at the lower end of the purification tank 1. A heater 10 is provided on the purification tank 1, and a temperature sensor 11 is installed on the purification tank 1.

[0019] When using a purification device to refine and purify perfluorosulfonic acid resin, the device is placed using support legs 12. After opening the end cap at the feed inlet 3, the perfluorosulfonic acid resin raw material and extraction solvent are added into the purification tank 1. The device is heated by heater 10 to fully dissolve the perfluorosulfonic acid resin raw material and mix it with the solvent to form a dispersion. During this process, temperature sensor 11 can detect the temperature in real time to provide a suitable temperature. After the dispersion is formed, extractant is added to the purification tank 1 and purification begins.

[0020] During the purification process, the extractant comes into contact with the dispersion for extraction and purification. The stirring motor 5 on the support 4 is started, and the stirring motor 5 drives the stirring rack 6 to rotate via the rotating shaft, thereby stirring and mixing the dispersion and extractant, which can increase the extraction effect. After stirring and mixing, the extract is allowed to stand to form two layers of liquid. The interface position of the two liquids is detected by the ultrasonic interface sensor 7 and feedback information is provided. Based on the information fed back by the ultrasonic interface sensor 7, the upper light liquid extraction structure 8 is adjusted, and then the upper light liquid is extracted. After extraction, the lower liquid is discharged using the drain pipe 9. The liquid containing impurities is collected, while the liquid containing perfluorosulfonic acid resin is further processed to obtain refined perfluorosulfonic acid resin.

[0021] According to the above implementation scheme, the upper light liquid extraction structure 8 includes a fixed rod 801, an installation component 802, an adjusting rod 803, a servo motor 804, a coupling 805, a lead screw 806, and a lifting suction pipe 807. The fixed rod 801 is fixed on the top cover 2, the installation component 802 is sleeved on the fixed rod 801, the adjusting rod 803 is fixed on the top cover 2, and the adjusting rod 803 and the top cover 2 are provided with through threaded holes. The servo motor 804 is set on the installation component 802, the coupling 805 is connected between the output shaft of the servo motor 804 and the lead screw 806, and the lower end of the lead screw 806 is connected in the threaded hole. The lifting suction pipe 807 is installed on the installation component 802.

[0022] Before extracting the upper light liquid, after the ultrasonic interface sensor 7 provides feedback, the servo motor 804 drives the lead screw 806 to rotate via the coupling 805. The lead screw 806 rotates and rises on the adjusting rod 803, thereby raising and lowering the mounting component 802 on the fixed rod 801. This, in turn, adjusts the height of the lifting suction pipe 807 so that the lower end of the lifting suction pipe 807 is located at the interface between the two liquids after stratification. Then, the external suction pump is started, and the upper light liquid is extracted using the lifting suction pipe 807.

[0023] The mounting assembly 802 includes a lifting plate 8021, a round hole 8022, a fixed sleeve 8023, a movable sleeve 8024, a through hole 8025, and a mounting screw 8026. The round hole 8022 is formed on the lifting plate 8021, and the lifting plate 8021 is sleeved on the fixed rod 801 through the round hole 8022. The fixed sleeve 8023 is fixed on the lifting plate 8021. The through hole 8025 is provided on the lifting plate 8021 and the fixed sleeve 8023. The mounting screw 8026 is provided on the movable sleeve 8024, and the end of the mounting screw 8026 is connected to the fixed sleeve 8023.

[0024] When using the upper light liquid extraction structure 8, during the movement of the mounting assembly 802, the lifting plate 8021 moves along the fixed rod 801 through the round hole 8022, thereby moving the lifting suction tube 807 at the movable sleeve 8024 and the fixed sleeve 8023. If it is necessary to adjust the initial position of the lifting suction tube 807 relative to the lifting plate 8021, the movable sleeve 8024 can be removed after loosening the mounting screw 8026, the relative height of the lifting suction tube 807 can be adjusted by moving it, and then the movable sleeve 8024 can be connected to the fixed sleeve 8023 using the mounting screw 8026 to fix the lifting suction tube 807.

[0025] It should be noted that the height of the mounting component 802 can be adjusted using the upper light liquid extraction structure 804, lead screw 806, and other structures, thereby moving the lifting suction tube 807. In conjunction with the ultrasonic interface sensor 7, this ensures that the end of the lifting suction tube 807 is close to the interface between the two liquids after extraction and purification, ensuring suction accuracy and avoiding significant errors. The lead screw 806 and adjusting rod 803 have a self-locking effect, ensuring the stability of the lifting suction tube 807 after height adjustment and guaranteeing the suction effect. Using the mounting component 802 to install the lifting suction tube 807 allows for adjustment of its initial height, offering high operational flexibility. The servo motor 804, mounted on the mounting component 802, moves with the lifting adjustment, saving space without affecting normal adjustment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
