Description

Technical Field

[0002] Ultrafiltration membrane separation technology (Membrane Separation Technique) is an emerging high-efficiency separation technology, which has been internationally recognized as the most promising major high-tech production technology from the late 20th century to the mid-21st century. Its basic principle is to use the selective screening performance of membrane pores to separate, purify and concentrate substances. It has been widely used in medicine, food, chemical industry, electric power, papermaking, printing and dyeing, water source management and seawater desalination and other fields;

In addition, the clamp fixing method often needs to be installed in a specific position, which may limit the layout flexibility of the pipeline and ultrafiltration membrane to a certain extent, so that the freedom of system design is subject to certain restrictions.

[0031] In this embodiment, when the ultrafiltration membrane 2 is installed on the frame 1, the ultrafiltration membrane 2 is placed on the supporting and fixing mechanism 3, and the circular plate 321 is pressed downward by the ultrafiltration membrane 2's own gravity. The circular plate 321 cooperates with the guide head 316 through the annular groove 322 to drive the fixing head 315 on the fixing arm 314 to flip inward with the impurity 313 as the axis, thereby fixing the lower end of the ultrafiltration membrane 2.

[0032] Specifically, the driving assembly 32 further includes a first spring 323 installed inside the supporting seat 311 , and the first spring 323 is located directly below the circular plate 321 .

[0033] In this embodiment, when the ultrafiltration membrane 2 is removed from the frame 1, the rebound pressure of the first spring 323 pushes the circular plate 321 to move upward, and the circular plate 321 cooperates with the guide head 316 through the annular groove 322 to drive the fixing head 315 on the fixing arm 314 to flip outward with the impurity 313 as the axis, thereby releasing the fixation of the lower end of the ultrafiltration membrane 2.

[0036] The matching component 42 includes brackets 421 fixed at both ends of the frame 1.

[0037] In this embodiment, the second spring 416 is squeezed by pulling the transverse plate 414 outward, and the transverse plate 414 drives the first pad 415 to separate from the ultrafiltration membrane 2, thereby releasing the reinforcement of multiple ultrafiltration membranes 2; and, the sliding sleeve 411 can slide longitudinally along the frame 1, so that the actuator 41 can position and protect the ultrafiltration membrane 2 at different heights.

[0044] When the ultrafiltration membrane 2 needs to be installed, the ultrafiltration membrane 2 is placed on the bearing and fixing mechanism 3, and the circular plate 321 is pressed downward by the ultrafiltration membrane 2's own gravity. The circular plate 321 drives the fixing head 315 on the fixing arm 314 to flip inward with the impurity 313 as the axis through the annular groove 322 and the guide head 316, thereby fixing the lower end of the ultrafiltration membrane 2; then, the sliding sleeve 411 is driven to slide longitudinally along the frame body 1 by pulling the cross plate 414 and cooperating with the cross frame 412, so that the actuator 41 can position and protect the ultrafiltration membrane 2 at different heights. After releasing the pulled cross plate 414, the first pad 415 on the cross plate 414 is pushed to fit with the ultrafiltration membrane 2 through the rebound pressure of the second spring 416, and cooperates with the second pad 422 on the bracket 421 to reinforce and protect the ultrafiltration membrane 2.
