Description

Diaphragm joint and diaphragm assembly

Technical Field

The utility model belongs to the field of hollow fiber membrane components, and particularly relates to a membrane joint and a membrane component.

Background

The membrane separation technology is an emerging technology for separating, concentrating or purifying by taking a separation membrane as a core, and is widely used in the fields of production and domestic water preparation, sewage purification, sea water desalination, special material separation and purification and the like. The separation membranes are in the forms of hollow fiber type, roll type, tubular type and the like, and are mainly divided into pressure type and immersed type membrane assemblies, wherein the pressure type membrane assemblies are quite wide.

When treating high turbid water quality, large-volume fibers, hairlines and the like possibly enter the membrane assembly along with water flow, are entangled, aggregated and the like and are accumulated in the membrane assembly, so that the use effect and even the service life of the membrane assembly are reduced.

Detailed Description

The present utility model will be described in further detail below with reference to the drawings and preferred embodiments, so that those skilled in the art can better understand the technical solutions of the present utility model.

1-2 illustrate a membrane connector comprising a membrane connector body 3, a filter end 31 disposed within the membrane connector body and connected to a liquid inlet end of a membrane module, and an external end 32 connected to a liquid inlet line; the filter end comprises a filter end main body 311, a filter end cavity 312 arranged in the filter end main body and a diaphragm 1 arranged in the filter end cavity; the external terminal comprises an external terminal main body 321 and an external terminal cavity 322 arranged in the external terminal main body; the external end cavity 322 is communicated with the filtering end cavity 312 through the diaphragm 1.

The outer diameter of the filtering end cavity is equal to the outer diameter of the external end main body; the filtering end main body is provided with internal threads; the external connection end main body is provided with external threads; the internal thread is matched with the external thread. This arrangement allows it to be fully adapted to existing membrane module operating equipment.

The mesh number of the diaphragm is 1-500 mesh. The material is ceramic inorganic material, organic polymer material such as PP, etc. and stainless steel material.

The periphery of the diaphragm joint main body is provided with evenly arranged bulges 2. This arrangement facilitates the installation of the diaphragm joint, since the assembly operating environment will have a lot of liquid.

FIG. 3 shows a membrane module comprising a membrane module body and a liquid inlet end 4 arranged on the membrane module; the liquid inlet end is connected with the diaphragm joint. The diaphragm joint can be connected with the liquid inlet end through threads.

The working principle of the utility model is as follows: after the diaphragm joint and the liquid inlet end of the diaphragm assembly are installed and debugged, the treatment liquid firstly enters the diaphragm 1 in the diaphragm joint, the pretreated feed liquid enters through the liquid inlet end of the diaphragm assembly, the filtered liquid is discharged from the filtered liquid outlet through the inner wall of the diaphragm wire under the action of pressure, and the concentrated liquid is discharged from the concentrated return port, so that the filtration of the treatment liquid is completed.

After short-time operation, the membrane sheet 1 is light in pollution, the reaction is started, and the filtrate is used for backwashing treatment; after long-time operation, when the backwashing effect is poor, the diaphragm joint can be stopped and removed for further cleaning treatment and even updating. After the cleaning is finished, starting up is continued.

According to the description of the utility model, the diaphragm joint is easy to realize automatic manufacture through a series of fixing steps, and mass production can be realized in a short time.

The foregoing is merely exemplary of the present utility model, and those skilled in the art should not be considered as limiting the utility model, since modifications may be made in the specific embodiments and application scope of the utility model in light of the teachings of the present utility model.
