Centrifuge and hanging rack thereof

Abstract

The invention relates to a centrifuge and a hanging rack thereof which are used for the manufacture process of a hollow fiber film and the assembly process of a filter. The technical proposal is as follows: a centrifuge comprises a base, a supporting platform arranged on the base, and a rotation platform rotatablely arranged on the supporting platform; the rotation platform is driven by a motor through a transmission mechanism; the centrifuge also comprises a first hanging rack group and a second hanging rack group that are arranged on the external edge of the rotation platform; the first hanging rack group comprises a plurality of first hanging racks with one end capable of being articulated on the rotation platform in a dismountable way; and the second hanging rack group comprises a plurality of second hanging racks with the middle parts capable of being articulated with the rotation platform in a dismountable way. The centrifuge and the hanging rack thereof have the advantages that the rotation platform is provided with the plurality of the first hanging racks and the second hanging racks, the efficiency for glue-pouring is improved, the first hanging racks and the second hanging racks are arranged vertically when the rotation platform is not in a rotation state and the glue is not easy to leak.

Description

technical field [0001] The invention relates to a centrifuge and its hanger, which are used in the manufacture of hollow fiber membranes and the assembly process of filters. Background technique [0002] The hollow cellulose nanofiltration membrane bundle of the nanofiltration membrane module is composed of thousands of nanofiltration membranes. During the production process of the nanofiltration membrane module, it is necessary to seal the two ends of the nanofiltration membrane bundle. The diameter of the nanofiltration membrane is very small. If the glue is filled in an ordinary way, the glue is not easy to enter the small gaps between the nanofiltration membranes. Therefore, a centrifuge is usually used for glue filling, and the nanofiltration membrane bundles that need to be glued are hung on the hanger. On the rotating table of the centrifuge, when the centrifuge rotates, the sealant is poured into the gap between the nanofiltration membranes under the action of centri...

AI Technical Summary

Problems solved by technology

However, for some long and large nanofiltration membrane modules, the glue filling process is much more difficult. If the large hanger is connected to the edge of the rotary table like the small hanger, the rotary table of the centrifuge must be made very high. It will cause the center of gravity of the centrifuge to be unstable; some of these large hangers are fixed on the rotary table along the diameter direction, that is, the middle part of the large hanger is fixed on the rotation center of the rotary table. However, if the large hanger is set in this way, Each centrifuge can only place one large hanger, the efficiency is very low, which seriously affects the production efficiency, and the large hanger placed in the rotation center is very inconvenient for taking and placing nanofiltration membrane modules, which will increase the working time. In addition, large The hanger is fixed at the center of the turntable so that it must be kept level all the time, and the sealant in the rubber tube is easy to leak, causing pollution
