Abstract

PURPOSE:To provide a filter membrane module which can easily be attached and detached to a membrane separation device. CONSTITUTION:The periphery edge part of a filter membrane module 4 has plural numbers of projections 8 which slides and contacts on the inner side face of the groove at the part fitted to grooves of a slit plate of a membrane separation device. Thereby, the module is fitted and fixed at these projections 8 to grooves of a slit plate of a membrane separation device, so that the contact area of the module 4 and the groove is made small and the module can easily be attached or detached to the device.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filtration membrane module of a membrane separation device used in a water treatment device or the like.

[0002]

2. Description of the Related Art Conventionally, a submerged membrane separation device used in a water treatment device has a plurality of filtration membrane modules arranged therein.
By applying a negative pressure to this filtration membrane module, the liquid to be treated is filtered by the filtration membrane. At this time, as shown in FIG. 3, the plurality of filtration membrane modules 3 are inserted in parallel along the groove 2 of the slit plate 1 of the membrane separation device at equal intervals.

[0003]

However, when the filtration membrane module 3 is inserted along the groove 2 of the slit plate 1 as described above, since the contact area between the filtration membrane module 3 and the groove 2 is large, friction or the like occurs. Therefore, it is difficult to insert and remove the filtration membrane module 3.

Further, when the filtration membrane module 3 is distorted or when foreign matters are present between the filtration membrane module 3 and the groove 2 of the slit plate 1, it is difficult to insert and remove the filtration membrane module 3. Is.

The present invention solves the above problems, and an object of the present invention is to provide a filtration membrane module that can be easily attached to and detached from a membrane separation device.

[0006]

In order to solve the above problems, the filtration membrane module of the present invention is a filtration membrane module which is inserted into a groove of a slit plate of a membrane separation device. A plurality of protrusions that are in sliding contact with the inner surface are provided.

[0007]

As described above, by providing a plurality of protrusions which are slidably contacted with the inner side surfaces of the groove in the groove of the slit plate of the membrane separation device in the peripheral portion of the filtration membrane module, The contact area between the membrane module and the groove is reduced, and the frictional force is reduced, so that the filtration membrane module can be easily attached and detached, and the filtration membrane module is fixed to the slit plate by this protrusion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, 4 shows a filtration membrane module, (a) is a front view, (b) is a left side view of (a). The filtration membrane module 4 comprises a rectangular flat plate-shaped membrane support 5 formed of vinyl chloride or the like, and an organic filtration membrane 6 such as an ultrafiltration membrane or a microfiltration membrane adhered and fixed to the front and back sides of the membrane support 5 to form a filtration membrane 6 A membrane permeated liquid suction tube 7 that communicates with the inside is provided. By applying a negative pressure through the permeated liquid suction pipe 7, the liquid to be treated can be filtered by the filtration membrane module 4.

A plurality of protrusions 8 are provided at appropriate intervals on the two parallel sides of the peripheral portion of the surface of the membrane support 5, and as shown in FIG. 2, the two sides having the protrusions 8 are formed. The filtration membrane module 4 can be fixed to the membrane separation device by inserting it into the groove 10 provided in the slit plate 9 of the membrane separation device.

When the filtration membrane module is manufactured to have a length of 1000 mm and a width of 500 mm, for example, the cross section has a major axis of 5 mm and a minor axis of 1 to 5.
A 2 mm membrane module with a long ellipse in the vertical direction, and a protrusion with a height of about 0.5 mm, is 6 to 6 per side of the membrane module.
20 can be provided.

The filtration membrane module 4 is attached to the groove 1 of the slit plate 9.
When inserting or removing along 0, as shown in FIG. 2, since the contact area between the protrusion 8 and the groove 10 of the filtration membrane module 4 is small, it is easy to take in and out.

When the filtration membrane module 4 or the slit plate 9 is distorted or the groove 10 of the slit plate 9 has an inappropriate width and the membrane module 4 is difficult to take in and out, the projection 8 is formed.
Can be trimmed to fit the groove 10.

[0013]

As described above, according to the present invention, a protrusion is provided on the peripheral portion of the filtration membrane module, and the portion having this protrusion is inserted into the groove of the slit plate of the membrane separation device, and the groove is formed by the protrusion. Since the structure is fixed, the contact area between the filtration membrane module and the groove is small, and the filtration membrane module can be easily attached and detached. Further, since the protrusion can be cut to fit the groove, the assembly of the membrane separation device can be easily performed.
