Description

TECHNICAL FIELD

[0001] The utility model relates to the ventilation field, concretely is a ventilation pipeline cleaning structure. BACKGROUND

[0002] The ventilation pipeline cleaning structure is a set of device combination for removing dust, dirt, sundries and other pollutants inside the ventilation pipeline.

[0003] The ventilation pipeline cleaning structure is disclosed in CN118253541B, which comprises a ventilation pipeline body, an air inlet filter screen and a rotating member installed in the middle part of the ventilation pipeline body. The rotating member comprises a rotating outer ring, a handle and a connecting part. The handle is fixedly connected to the outer side of the rotating outer ring. The connecting part is located in the inner ring of the rotating outer ring and is fixedly connected with the rotating outer ring. An air outlet is fixedly installed on the inner side top surface of the rotating inner ring. There are not less than two air outlets. A cleaning assembly is symmetrically arranged on both sides of the rotating outer ring. In the existing ventilation pipeline cleaning technical field, rotating cleaning with a brush is one of the most common methods. In this method, the brush is installed on a rotatable shaft or a driving device, and then it is stretched into the ventilation pipeline. The brush is driven to rotate at high speed by a motor or other power source. The dirt is removed by the friction between the bristles and the inner wall of the pipeline. However, in the actual application process, when the brush is in contact with the pipeline for rotating cleaning, many problems that seriously affect the cleaning effect are exposed. The dust and dirt on the inner wall of the ventilation pipeline have complex composition and different adhesion. Some of the dust particles are small and have certain viscosity. For example, in some industrial production environments, dust mixtures containing oil stains and chemical residues may accumulate in the ventilation pipeline. Although a part of the loose dust can be cleaned when the brush continuously rotates in contact with the pipeline, it is difficult to completely remove the dirt that is firmly attached to the inner wall of the pipeline and the dust that is in close contact with the inner side of the brush. Because the brush is in close friction with the pipeline all the time, the brushed dust is easy to accumulate and compact on the inner side of the brush. This is because the inner side of the brush is relatively closed during rotation, and the dust is difficult to naturally fall off. Moreover, the newly brushed dust will continuously stick to the accumulated dust, gradually forming a compact dust layer. This dust layer will seriously hinder the subsequent cleaning efficiency of the brush, reduce the effective friction coefficient between the brush and the inner wall of the pipeline, and further reduce the cleaning ability of the dirt on the inner wall of the pipeline.
