Description

Technical Field

[0001] The utility model relates to the technical field of short fiber filtration and cleaning of air ducts, in particular to a high-stability filtration spray cleaning mechanism. Background Art

[0002] In the finishing field of the textile and printing industry, in the processes of equipment such as stenter machines, drying machines, calendering machines, and steaming machines, and waste heat recovery systems and oil fume purification systems that emit waste gas containing short fiber fluff, the cleaning of short fiber fluff attached to the filter screen is usually carried out manually at regular intervals. There are problems of large workload and poor working environment. At the same time, due to the failure to clean in time, there is a problem of filter screen blockage, resulting in unsmooth exhaust gas discharge, and further causing oil dripping inside equipment such as stenter machines, seriously affecting product quality and increasing the power consumption of the fan. Short fiber fluff adheres inside the air duct, posing a great fire risk. Short fiber fluff adheres to the heat exchange surface of the waste heat recovery equipment, reducing the heat exchange efficiency and increasing the power consumption. In addition, in the polishing field of the electroplating industry, short fiber fluff falling from the cloth polishing wheel will adhere inside the waste gas ventilation duct and the waste gas treatment environmental protection equipment, posing a fire risk and affecting the normal operation of the waste gas treatment environmental protection equipment, resulting in the problem of excessive emissions.

[0003] A Chinese patent, a filter system convenient for automatic cleaning (publication number CN220677193U, application date August 8, 2023), rotatably connects a filter component at the axial center of the housing. The filter component can filter short fibers and perform adsorption and cleaning treatment through a negative pressure device cooperating with a negative pressure cleaning head. At the same time, it is also cleaned through a spray component, thereby ensuring the normal operation of waste gas treatment environmental protection equipment for waste heat recovery equipment and achieving the purpose of meeting the emissions standard. However, the spray component set in this scheme is only arranged through the filter component, and the support structure is a single cantilever structure. The support stability of the spray pipe and the rigidity of the filter component are relatively poor, and it is necessary to further strengthen the support and fixing structure to improve the overall operation stability.
