Description

Technical Field

[0001] The utility model relates to the field of pipeline cleaning equipment, in particular to a flue gas pipeline brushing and maintenance equipment. Background Art

[0002] Waste heat steam generation equipment usually uses hot flue gas. After the flue gas is purified, it still inevitably contains dust, which is very easy to adhere to the inner wall of the pipe body. The gradual thickening of the attached ash layer will directly affect the pipeline flux, and long-term adhesion can easily cause dust compaction.

[0003] The solution to the accumulation of dust in the inner cavity of the pipe body is generally to use a soot blower to avoid dust accumulation in the pipe. However, due to objective conditions such as hot flue gas and limited coverage area of ​​the soot blower, the pipe still needs to be cleaned regularly. The existing pipeline cleaning work is difficult to carry out, and manual tools are generally used for manual dust removal. It is often difficult to clean the elbow part and the deep part of the pipe. Thorough cleaning also involves disassembly and maintenance operations, and the process is cumbersome. For the above situation, there is currently a lack of specific solutions. Utility Model Content

[0005] The device comprises a flexible shaft, wherein the flexible shaft is a hollow flexible shaft;

[0006] The front end of the flexible shaft is rotatably provided with a rotating shell, and a plurality of tracheas are arranged on the rotating shell, the exhaust port of the trachea is directed backward, and the rotating shell, the flexible shaft and the inner cavity of the trachea are communicated;

[0007] The flexible shaft is provided with bristles in an array;

[0008] An airtight ring is rotatably arranged at the rear of the flexible shaft, a mechanical seal is arranged between the airtight ring and the flexible shaft, and a quick connector is arranged on the airtight ring;

[0009] The rear end of the flexible shaft is provided with a rotating base;

[0010] A connecting sleeve is rotatably arranged outside the flexible shaft, and the connecting sleeve is a corrugated pipe or a pipe-in-pipe structure. The connecting sleeve is used to restrict the rotation direction of the flexible shaft.

[0011] The effect achieved in this way is to fold the connecting sleeve so that the flexible shaft part is exposed, the rotating base power is connected to the rotating equipment, the rotating shell part and the front part of the flexible shaft are inserted into the pipeline to be cleaned, and the flexible shaft part is inserted into the pipeline by advancing from the back to the front, and the connecting sleeve pipe mouth is connected to the pipeline to be cleaned by using a hose clamp; the quick connector is connected to the compressed air, and the compressed air is introduced first, and the rotating equipment is started. Under the action of the rotating equipment and the rotating flexible shaft, the equipment continues to drill into the pipeline, and assists in pushing the rotating power equipment to follow the flexible shaft forward, the connecting sleeve is continuously stored, the flexible shaft is continuously advanced, and the bristles complete the brushing of the inner wall of the pipeline. When retreating, reduce the power of the rotating equipment or stop it directly, and manually pull it back.

[0012] The beneficial effects of the utility model are as follows: the utility model solves the problem of difficulty in cleaning the dust in the inner cavity of the pipe body in the prior art, realizes the internal brushing maintenance of the pipeline, and ensures the pipeline flux. In particular, the equipment guides the lead backward with the rotation power and pressure, and the equipment can pass a small number of elbows during the progressive process, which greatly reduces the maintenance workload.
