Most of the prior screens are not provided with a purging pipe, so that packing accumulation and leakage are easy to occur; or the purging pipe is only arranged outside the screen, purging is not thorough, and filler climbing along the screen is easy to occur, so that filler leakage is caused; for a plane screen, suspended fillers are easy to accumulate at the screen, and meanwhile, larger buoyancy is caused to the bottom of the screen; the installation of the screen is complex, the construction difficulty is high, the material waste is high, the part close to the wall is not easy to seal, and the screen is easy to deform; the phenomena of material running, accumulation, blockage and the like are easy to occur.

In order to solve the problems, the application provides an inside and outside purging tubular screen applied to sewage treatment filtering suspension filler.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects in the prior art, and provides an internal and external purging tubular screen for filtering suspended filler in sewage treatment, which utilizes the smooth surface of a tubular screen pipe to greatly reduce the buoyancy of the filler to the screen, and is obviously superior to a plane square screen; the condition of filler accumulation is basically avoided by adopting the mode of internal blowing and external blowing; the process is easy to install and simple in structure; the multi-sieve tube type water draining device can be provided with a multi-sieve tube type water draining device which can drain water in a combined manner, and the defect that the flow area of the tubular sieve is insufficient is overcome.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an inside and outside tubular screen cloth that sweeps for sewage treatment filters suspension filler, includes the screen cloth pipe, sweep the pipe in being provided with in the screen cloth pipe, the below of screen cloth pipe is provided with outer the pipe that sweeps, it is equipped with rather than a plurality of conveyer pipes of fixed connection to run through on the screen cloth pipe, the bottom that sweeps the pipe in runs through and is equipped with a plurality of first through-holes, the bottom that sweeps the pipe outward runs through and is equipped with a plurality of second through-holes, it is equipped with a plurality of sieve meshes to run through on the screen cloth pipe.

Preferably, the material of the screen pipe is low-carbon steel zinc-plated alloy.

Preferably, the first through holes and the second through holes are distributed at equal intervals.

Preferably, the conveying pipe is arranged in an L shape.

Preferably, the diameters of the first through hole and the second through hole are both 4mm.

Compared with the prior art, the utility model, its beneficial effect does:

1. when having guaranteed the area of overflowing through the tubular screen cloth, utilize the stability of circle, increased screen cloth intensity, do benefit to the construction installation, very big reduction the probability of screen cloth maintenance.

2. The device can also be used in any container and tank body with filling materials, and can be used for overflowing and pumping.

3. And an internal and external double-blowing mode is adopted, so that the filler outside the screen is blown more directly and more thoroughly.

4. The combination of multiple sieve tubes avoids the defect that the tubular sieve can only be used for small-scale sewage treatment facilities.

In conclusion, the smooth surface of the tubular sieve tube is utilized, so that the buoyancy of the filler to the sieve is greatly reduced, and the sieve is obviously superior to a plane square sieve; the condition of filler accumulation is basically avoided by adopting the mode of internal blowing and external blowing; the process is easy to install and simple in structure; the multi-sieve tube type water draining device can be provided with a multi-sieve tube type water draining device which can drain water in a combined manner, and the defect that the flow area of the tubular sieve is insufficient is overcome.
