In the highland mine machinery air filter element cleaning device and its use method, when the air filter element is cleaned, the driving source can be started to operate to drive the polyurethane adhesive tape to rotate continuously, and the polyurethane adhesive tape can be used to mechanically clean the outer surface of the air filter element, thereby improving the cleaning effect of the air filter element. When the polyurethane adhesive tape rotates, the driving force can also drive the two disturbance rotating rods to rotate synchronously, and the polyurethane adhesive tape abutting against the outside of the disturbance rotating rod can be vibrated to reduce the probability of dust adsorbing on the outside of the polyurethane adhesive tape; 3. In the highland mine machinery air filter element cleaning device and its use method, when the air filter element is extruded and fixed and the internal particles and dust are removed by rotating centrifugation, the driving force for driving the extrusion seat to move up and down and rotate operates outside the lower connecting rod, and the inner recess in the lower connecting rod ensures that the operation of driving the lower connecting rod to move up and down and rotate does not conflict and interfere with each other, so that the air filter element extrusion and rotation centrifugal cleaning operation occupies a small area. 4.

[0022] The working principle is as follows: when the air filter is cleaned, the door plate structure of the sealed cleaning box 20 is opened, the air filter is moved to the inner side of the telescopic positioning assembly 601 through manual assembly, the telescopic positioning assembly 601 is started to operate, and the air filter at both ends between the two telescopic positioning assemblies 601 is extruded and fixed. Meanwhile, in the process of fixing the air filter, the elastic positioning assembly 605 in contact with the air filter is also operated, and the upper and lower sides of the air filter are automatically extruded and fixed through the elastic positioning assembly 605, so that the air filter does not shake, deviate or even fall off when the centrifugal dust removal of the air filter is driven at high speed. When the air filter is centrifugally dusted, the gear driving assembly 604 is started to operate, the air filter fixedly connected with the gear driving assembly 604 is driven to rotate at high speed, and the dust in the air filter is moved to the outer side of the air filter.

[0023] It should be noted that when the air filter is dusted, the air outside can be transmitted to the inside of the sealed cleaning box 20 through the centrifugal ventilator 30, the dusting operation of the air filter is accelerated through the air blowing, the dust separated after the dusting operation is pushed into the inside of the cloth bag dust collector 70 through the pushing force generated by the operation of the blower 40, and the dust particles in the gas are adsorbed through the cloth bag dust collector 70.

[0024] Further, when the air filter element is cleaned, the rotating cleaning structure 50 is started to operate, the outer surface of the air filter element is vibrated and cleaned, and the cleaning effect of the air filter element is improved.

When the disturbance rotating rod 505 and the polyurethane tape 503 on the outer side of the disturbance rotating rod 505 come into contact, the polyurethane tape 503 for cleaning dust can be mechanically vibrated to reduce the probability of dust adhering to the surface of the polyurethane tape 503.
