Problems solved by technology
[0002] In some hydraulically driven drive structures, such as propellers, motors or hydraulic pumps, there are usually some metal friction pairs inside the drive structure, and some metal particles will be generated at the metal friction pairs during normal operation of the drive structure. The particles will enter the hydraulic oil, and the metal particles will flow into the metal friction pair of the drive structure with the flow of hydraulic oil, which may cause the drive structure to run stuck.
[0003] Therefore, in the casing filled with hydraulic oil of the drive structure, magnet equipment for absorbing metal particles is usually placed. The magnet equipment absorbs metal particles in the hydraulic oil, reduces the metal particles flowing with the hydraulic oil, and reduces the occurrence of operation jams in the drive structure. The possibility of stagnation, but when cleaning this kind of magnet equipment, it is usually necessary to empty the hydraulic oil in the drive structure, and then take out the magnet equipment for cleaning. The cleaning process is more cumbersome

Abstract
The invention discloses a metal particle adsorption device and belongs to the field of filtering equipment. A mounting hole is formed in a hydraulic oil-filled shell of a driving structure; a connecting base of the metal particle adsorption device is connected to the mounting hole in a sealing manner; a through hole of the connecting base is connected to the outside world and the interior of the shell; and an airbag unit inside one end of the through hole is used for closing or opening the through hole. When a magnet is required to suck metal particles in hydraulic oil, the airbag unit opens the through hole, and the hydraulic oil flows in the shell, the magnet fixed to a compression plate at the other end of the through hole can adsorb the metal particles, the compression plate covers thethrough hole and is connected to the connecting base in a sealing manner, and the hydraulic oil does not flow out. When the metal particles on the magnet need to be cleaned, the airbag unit is controlled to close the through hole, and the hydraulic oil is closed by the airbag unit and does not flow out of the through hole. At the moment, the compression plate and the magnet on the connecting basecan be dismantled, the cleaning of the magnet is directly completed; the hydraulic oil in the shell does not need to be emptied; and the cleaning process of the magnet equipment is relatively simple.
