Automatic cleaning device for vacuum suction filter screen

The utility model discloses an automatic cleaning device for a vacuum suction filter screen, which is characterized in that an airflow blowing device is additionally arranged in the reverse direction of the vacuum filter screen and comprises an air inlet pipe, a profiling blowing cap and a communicating hose; the profiling air blowing cap is coiled on the surface of the vacuum filter screen, the air inlet pipe is communicated with the profiling air blowing cap through the communication hose, and a plurality of air blowing holes are uniformly distributed in the profiling air blowing cap and used for blowing air to the vacuum filter screen. The profiling blowing cap is composed of eight arc-shaped copper pipes, and the arc-shaped copper pipes are communicated through hoses. And blowing holes are uniformly formed in each arc-shaped copper pipe at intervals of 1.2 mm. The problem of blockage of the vacuum filter screen can be avoided, the material pumping efficiency of equipment is improved, and the frequency of
