specific Embodiment approach 1

[0012] Specific implementation mode one: as figure 1 As shown, the steps of the quick connection method of the submerged membrane pool membrane modules and pipelines in this embodiment are as follows:

[0013] Step 1. First, fasten a rubber sealing ring at the connection joint of each branch pipe on the membrane module, and one half of each rubber sealing ring is fixedly sleeved at the connection end of each branch pipe of the membrane module, and the other half is turned over. on the front half of the rubber seal;

[0014] Step 2. Then connect each branch pipe of the suction pipeline with the connecting ends of each branch pipe of the membrane module axially, so as to ensure that the axial installation distance between each branch pipe of the suction pipeline and the connection ends of each branch pipe of the membrane module is less than 10㎜;

[0015] Step 3. Set the folded part of each rubber sealing ring on the connecting end of a branch of the corresponding suction pipel...

specific Embodiment approach 2

[0018] Specific embodiment 2: The length of the rubber sealing ring described in step 1 of this embodiment is 100-200 mm. Such a design can improve the airtightness of the suction pipeline. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Specific implementation mode three: the length of the ring snap-off pipe clip described in step four of this implementation mode is 100-200 mm. Such a design can improve the airtightness of the suction pipeline. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an immersed type membrane cisterna membrane assembly and a pipeline fast connecting and assembling method, which relate to a fast connecting and assembling method. The invention solves the problem of inconvenient membrane thread cleaning and replacement caused by that the prior art does not have the immersed type membrane cisterna membrane assembly or the pipeline fast connecting and assembling method. The method comprises the following steps: (1) firstly, tightly sheathing and installing a rubber sealing ring at the connection part of each branched pipe on a membrane assembly, wherein one half of each rubber sealing ring is fixedly sheathed on the connecting end part of each branched pipe of the membrane assembly, and the other half of the rubber sealing ring is turned and sheathed on the front half of the rubber sealing ring; (2) ensuring that the axial installation gap of the connecting end of each branched pipe of pumping and sucking pipelines and each branched pipe of the membrane assembly is less than 10mm; (3) sheathing and installing the turning part of each rubber sealing ring on the connecting end of one branched pipe of the corresponding pumping and sucking pipeline; and (4) adopting an annular buckling pipe clamp to be tightly buckled on the outer end surface of the rubber sealing ring. The fast connecting and assembling method of the invention is simple and convenient, greatly reduces the work load of the membrane thread cleaning and replacement, and is convenient for outline chemical cleaning of the membrane assembly and the membrane thread replacement.

Description

technical field [0001] The invention relates to a coupling method, in particular to a quick coupling method of a membrane module and a pipeline. Background technique [0002] Submerged membrane technology not only has the function of efficiently separating pollutants, but also has the characteristics of low energy consumption and easy industrialization, so submerged membrane technology has a good application prospect in drinking water treatment. Microfiltration and ultrafiltration membrane technologies usually adopt a modular design in large-scale drinking water treatment projects. Several submerged membrane modules are arranged in each submerged membrane tank, and the membrane modules are connected to the suction pipeline. Since the membrane module needs to be cleaned regularly off-line and the membrane filaments need to be replaced, the connection between the membrane module and the suction line needs to be flexible to reduce the maintenance workload. However, there is cu...
