Machining device for hollow fiber ultrafiltration membranes

Abstract

The invention discloses a machining device for hollow fiber ultrafiltration membranes. The machining device comprises a worktable; support legs are fixedly connected to the two sides of the bottom ofthe worktable; a connecting cylinder is fixedly connected to the right side of the top of the worktable; the top of the connecting cylinder is in threaded connection with a first screw rod; and the bottom of the first screw rod movably penetrates through the top of the connecting cylinder, and extends into the connecting cylinder. According to the machining device for the hollow fiber ultrafiltration membranes, through the arrangement of the worktable and the connecting cylinder and cooperative use of the first screw rod, a pressing plate, an iron ring, an inflation pad, a fixed ring, a vertical plate, a top plate, a hydraulic cylinder, a connecting plate, a blade, a fixed plate, a stretchable rod, a connecting ring, a first spring, a limiting ring, a second spring, a pressing block, a return spring, an iron plate, a rubber column, a pull rope, elastic cloth, a short plate, a ring and a magnet, the hollow fiber ultrafiltration membranes can be effectively fixed, the displacement of thehollow fiber ultrafiltration membranes in the cutting process is prevented, and it is guaranteed that no length error exists after cutting.

Description

technical field [0001] The invention relates to the technical field of processing devices, in particular to a processing device for hollow fiber ultrafiltration membranes. Background technique [0002] Hollow fiber ultrafiltration membrane is a kind of ultrafiltration membrane. It is the most mature and advanced technology in ultrafiltration technology. The hollow fiber tube wall is covered with micropores. It can reach thousands to hundreds of thousands. Ultrafiltration is a dynamic filtration process. The intercepted substances can be removed with the concentrated water without clogging the membrane surface. It can run continuously for a long time. The ultrafiltration membrane is one of the earliest developed polymer separation membranes. After the fiber ultrafiltration membrane is produced, it is necessary to use a processing device to cut it to make the length meet the requirements of the staff. However, when the current processing device is used, it cannot effectively f...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a processing device for hollow fiber ultrafiltration membranes, which solves the problem that when the processing device is in use, the hollow fiber ultrafiltration membranes cannot be effectively fixed, causing it to easily appear during the cutting process. The displacement caused the length error of the hollow fiber ultrafiltration membrane after cutting, which caused a lot of trouble to the staff
