After the membrane module device is used for a period of time, a lot of sludge is adhered to the outer surface of the membrane wire after long-term use, and the membrane wire needs to be periodically cleaned.

At present, aiming at a large membrane module device, generally, an adjusting ring is arranged on the membrane module device, and after the whole membrane module device is hoisted out by a hoisting device, the membrane module device is cleaned by professional staff and equipment; but along with rural sewage treatment project's propulsion, a lot of remote scattered are in rural often can install and set up miniature membrane group ware, and inner structure is compact, and water treatment volume is little and set up remote, when washing the membrane, if adopt the mode of hoist and mount, then with high costs, and the hoist and mount in-process because inner setting structure is compact, the hoist and mount bumps easily, is difficult for even moving out.

SUMMERY OF THE UTILITY MODEL

The not enough to above-mentioned prior art, the utility model aims to solve the technical problem that to the sewage treatment device of small and exquisite, the compactness of structure, realize that low cost, efficient membrane silk wash. The event the utility model provides a fixed assembled membrane group ware of microminiature dispersion utilizes membrane pond pool wall, assembles the membrane silk burst of inside, realizes dismantling the washing, and area is little, and the washing cost is low.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a microminiature dispersion fixed assembled membrane group device, which has the key technology that: the membrane support comprises an upper membrane frame and a lower membrane frame which are consistent in structure, the outer frames of the upper membrane frame and the lower membrane frame are fixed on the wall of the membrane pool, the upper membrane frame is arranged right above the lower membrane frame, two rows of membrane yarn clamping rows are arranged on the opposite surface sides of the upper membrane frame and the lower membrane frame, N blocking pieces are uniformly distributed on each row of membrane yarn clamping rows, and the membrane yarn is arranged between every two blocking pieces;

the aeration main pipe extends into the top of the membrane pool, and the aeration main pipe extends into the bottom of the membrane pool and then is divided into M aeration branch pipes, and each aeration branch pipe is provided with an aeration hole facing the bottom of the membrane pool.

Through the design, the membrane yarn is installed between every two blocking pieces in a slicing mode, and when the membrane yarn needs to be cleaned, the membrane yarn is directly taken out to be cleaned.

Furthermore, the tail end of the aeration branch pipe is opened, and the diameter of the tail end opening of the aeration branch pipe is larger than the aperture of the aeration hole.

When the aeration holes of the aeration branch pipes are blocked, the aeration pump is repeatedly switched on and off to enable sludge in the aeration branch pipes to reciprocate rapidly, so that sludge at the orifices of the aeration holes can be rapidly cleaned. The pipe diameter of the tail end opening of the aeration branch pipe is set to be larger than the aperture of the aeration hole, so that air flow can be rapidly discharged from the tail end opening of the aeration branch pipe, and therefore sludge in the aeration branch pipe flows.

According to a further technical scheme, the tail end of each aeration branch pipe is bent downwards, so that the tail end opening of each aeration branch pipe faces the bottom of the membrane pool, and the height of the downward bent port at the tail end of each aeration branch pipe is lower than the set height of each aeration branch pipe.

The end of the aeration branch pipe is bent downwards as the water is deeper and the water pressure is higher, so that the air pressure can not be discharged from the end just during normal aeration, namely all the air is discharged from the aeration holes just. Play the role of stable aeration. When the aeration hole is blocked, the inflation pressure is increased, and the air is rapidly inflated and cut off, so that the sludge performs reciprocating motion together, the sludge is driven to move together, and the blocked aeration hole is communicated.

Still further, in order to support aeration and make aeration more stable, the bottom of the membrane tank is also provided with an aeration pipe support frame.

Still further, in order to collect the effluent, membrane silk upper portion still is equipped with membrane water collection frame, membrane water collection frame top is provided with the delivery port. Effectively avoids the mutual pollution caused by the remixing of the sewage and the treated water.

The utility model has the advantages that:

the microminiature dispersion fixed assembly type membrane module device is provided, membrane filaments inside the membrane module device are assembled in a fragmentation mode through the membrane pool wall, disassembly and cleaning are achieved, the occupied area is small, and the cleaning cost is low. The aeration pipe is easy to dredge due to blockage, and the service life is long.
