With the completion of the cleaning of the clogging impurities inside the inner core 301 and the outer core 302, the through hole will resume the dredging state, and the flow velocity value detected by the flow velocity sensor will gradually increase and reach the set flow velocity preset value. The controller controls the power-off of the electromagnetic limiting plate 105, and drives the magnetic movable plate 102 and the magnetic movable plate 102 to move close to the end of the electromagnetic limiting plate 105 under the elastic force of the return spring, so that the distance value detected by the distance sensor decreases, and the control The controller controls the rotational speed of the drive motor 309 to be reduced to zero, and the device resumes its normal working condition.

And when the flow velocity value detected by the flow velocity sensor is less than the set minimum flow velocity preset value, it shows that the amount of impurities collected inside the inner core 301 and the outer core 302 has reached the maximum degree at this time, and only by the extrusion of the inner core 301 and the outer core 302 If the pressure deformation and the rotation collision of the cleaning rod 306 cannot realize its cleaning function, the controller controls the gas supply line to stop the gas supply, and the controller controls all components in the device to cut off the power, open the shell assembly 4 and clean the filter element assembly 3 The internal inner core 301 and outer core 302 are removed and replaced to complete the replacement and maintenance of the filter element assembly 3 in the device, so as to avoid affecting subsequent use.

The device has high blockage removal efficiency and good blockage removal effect. Multiple components cooperate with each other to work together. The structure has strong versatility and good linkage. .

Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still It is possible to modify the technical solutions recorded in the foregoing embodiments, or to perform equivalent replacements on some of the technical features.
