After long-time use, the alum flowers can scale and accumulate on the inclined tube, and the using effect is seriously influenced.

The inclined tube is buried in water and is difficult to clean, a long-handle brush is used for cleaning manually in a common cleaning method at present, and the inclined tube is compact in structure, cannot be clearly seen whether to be cleaned or not under water, is easy to damage the inclined tube structure after being vigorously brushed, and is floated upwards, so that the danger that personnel fall down into a pool is also caused.

Disclosure of Invention

The utility model aims to provide a high-efficiency cleaning device for inclined pipes of a sedimentation tank, aiming at solving the problem that the existing inclined pipes are difficult to clean; the device is connected with an air pipe of a biochemical pool/filter pool, and an air gun is used for cleaning the inclined pipe, so that the problem that a long-handle brush needs to be manually and vigorously used for cleaning is solved; by designing the aeration holes at the tail end of the air gun, the stress of the inclined tube can be ensured to be uniform, and the condition that the inclined tube floats upwards due to structural damage is reduced; by arranging the air valve, the air quantity can be adjusted according to needs, so that the inclined pipe is cleaned more cleanly and conveniently; and the valves at the two ends are arranged, so that the maintenance and the replacement of the air pipe are facilitated.

In order to realize the aim, the utility model designs a high-efficiency cleaning device for the inclined tube of the sedimentation tank; the device comprises an air pipe connecting pipe, wherein the air pipe connecting pipe is connected with an air pipe of a biochemical pool/filter pool, the other end of the air pipe connecting pipe is connected with a hose, a bent air gun is connected onto the hose, the bent air gun consists of a horizontal pipe and a cleaning pipe which is inclined downwards, and an included angle a formed by the horizontal pipe and the cleaning pipe is 120 degrees and 140 degrees; the scavenge pipe bottom mouth of pipe is sealed, just a plurality of aeration holes have evenly been seted up to scavenge pipe lower extreme outer wall circumference direction (guarantee that the pipe chute receives the gas impact force balanced, prevent that the pipe chute from because of the uneven come-up of certain orientation atress).

The air pipe is an air source air pipe, not only can be a condensate water air pipe on a biochemical tank, or a backwashing air pipe of a rear-end filter tank of a high-efficiency sedimentation tank, but also utilizes the existing resources without additionally arranging a fan.

Further, the horizontal pipe and the cleaning pipe form an included angle a of 120 degrees.

Still further, the diameter of the bending air gun is 16-40 mm.

Still further, be provided with fixed ball valve (it is the switch of ventilating, adjusts when needing to use equipment washing pipe chute) on the tuber pipe connecting pipe.

Still further, the level pipe is provided with a butterfly valve (adjusting the wind volume in the pipe).

The principle of the utility model

The utility model has the advantages that:

1. the utility model discloses an use the air gun to wash the pipe chute, make the perpendicular atress of pipe wall, the amount of wind is adjusted to the accessible valve, and the scale deposit can be complete on the pipe wall cleans.

2. The utility model discloses do not need artifical application of force, only need handheld transformation hard tube to reciprocate, practice thrift artificial resources, reduced the danger that falls in the pond among the cleaning process.

3. The utility model discloses the bubble colour and the muddy degree that the accessible was emitted judge whether sanitization, the cleaning performance is more directly perceived.

4. The utility model discloses an utilize current facility equipment, carry out the innovative design, the equipment fixing concatenation is simple simultaneously, and is with low costs.

Detailed Description

The invention is described in further detail below with reference to the figures and specific embodiments for the understanding of those skilled in the art.

The high-efficiency sedimentation tank inclined tube cleaning device is shown in figure 1; the device comprises an air pipe connecting pipe 1, wherein the air pipe connecting pipe 1 is connected with an air pipe 2 of a biochemical pond/filter pool, and a fixed ball valve 5 is arranged on the air pipe connecting pipe 1;

the other end of the air pipe connecting pipe 1 is connected with a hose 3, a bent air gun 4 with the diameter of 16-40mm is connected onto the hose 3, the bent air gun 4 consists of a horizontal pipe 4.1 and a cleaning pipe 4.2 which is inclined downwards, and an included angle a formed by the horizontal pipe 4.1 and the cleaning pipe 4.2 is 120 degrees; a butterfly valve 6 is arranged on the horizontal pipe 4.1;
