Anti-loosening joint for immersed ultrafiltration membrane

Abstract

The invention belongs to the field of membrane assemblies, and particularly relates to an anti-loose joint for an immersed ultrafiltration membrane. The anti-loose joint comprises a connecting elbow,a connecting blocking sheet, a connecting lock nut and a connecting movable joint, wherein one end of the connecting elbow is provided with an elbow socket, the elbow socket is connected with the water production end of an immersed ultrafiltration membrane main body in a pluggable matching manner, the elbow at the other end of the connecting elbow is connected with the joint socket of the connecting movable joint in a pluggable matching manner, the connecting movable joint comprises the joint socket, a joint arranged on the periphery of joint socket and a blocking ring arranged on the periphery of the joint, joint slots are formed in the joint, the connecting blocking sheet comprises a clamping ring, a blocking sheet supporting block connected with the clamping ring and a plug pin arrangedon the blocking sheet supporting block, the front end of the plug pin is matched with the joint slot, the tail end of the plug pin is matched with the lock nut catch slot of the connecting lock nut,and the inner diameter of the camping ring is matched with the outer diameter of the other end of the connecting elbow. According to the invention, in-situ dismounting of the membrane module can be realized.

Description

technical field [0001] The invention belongs to the field of membrane modules, and in particular relates to an anti-loosening joint for submerged ultrafiltration membranes. Background technique [0002] The submerged ultrafiltration device takes the integrated module of the submerged ultrafiltration membrane module (hereinafter referred to as: submerged ultrafiltration machine) as the central processing unit, equipped with specially designed water pumps, pipelines, valves, cleaning units, dosing units and Automatic control unit, etc., forming a closed-circuit continuous operation ultrafiltration system. When the membrane produces water, the raw water is filtered through the ultrafiltration membrane under the negative pressure suction of the water production pump to achieve the purpose of physical separation and purification ( Figure 6 shown). [0003] The structural design of the submerged ultrafiltration membrane machine should consider the following factors: 1. Whether t...

Problems solved by technology

[0004] In the traditional design, it is mostly installed in the form of lock female thread connection. When the membrane module is performing water production or cleaning, due to the periodic aeration at the bottom, the membrane module is likely to vibrate, so that the thread at the connection between the membrane module and the water production main pipe The product water connector is loose, which eventually leads to unqualified water production of the membrane module

If the number of loose membrane modules is large, it will also damage the negative pressure suction function of the overall water production pipeline
