Problems solved by technology

In the application process of membrane technology, especially in the application of membrane stacks with stacked membranes, the distance between membranes cannot match the circulation rate of water to be treated in different application environments, which often leads to sticking of adjacent membranes. In addition, because the diaphragm cannot be fixed well, it will cause the diaphragm to swing and affect the quality of water purification.

Abstract

The invention discloses a fixing device for axial fastening of a diaphragm assembly. A support pipe is orderly provided with a first pressure plate, a plurality of membrane modules and a second pressure plate. A connection sleeve of the membrane assembly sleeves the support pipe. A support frame is arranged outside the connection sleeve. The outer side wall of the connection sleeve is connected tothe inner side wall of the support frame through a connection rod. Two ends of each one of the support frame and the connection sleeve along the axial direction are coated with filter films. The inner side wall of the support frame, the outer side wall of the connection sleeve and the cavity between the filter films at the two ends of the axial line are used for storing the filtrate filtered through the filter films. The filtrate passes through the connection sleeve and a through hole of the support pipe, enters the support pipe and stretches out of the support pipe. The two opposite outer side walls of the support frame are provided with adjustment rods. A thread positioning rod is sleeved with a plurality of adjusting rings. One axial end of the adjustment rod is fixed to the outer sidewall of the support frame and the other axial end is slidingly connected along the circumference of the outer wall of the adjusting ring. The fixing device can effectively prevent the movement of thediaphragm and the adhesion between the diaphragms.

Description

Technical field [0001] The invention relates to the technical field of membrane bioreactors, in particular to a fixing device for axial fastening of a diaphragm assembly. Background technique [0002] In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new type of water treatment technology that combines activated sludge method and membrane separation technology.
