S4.1, the case where vacuum pump observes filtered fluid in vacuum water tank well is opened, 10 minutes primary to 30 observations, observes 3 left sides The right side is started step plug (26) Ru more muddy, is inserted into filter medium with rod iron, being repeatedly inserted into and extract 30 times or so makes it Consolidation is added to original and is depressed into position in addition filter medium；

S5.1, it opens motor and drives screw rod (32) rotation, screw rod (32) rotation speed is made to go to 900 turns to per minute 500.

3. a kind of operating method of filter device as claimed in claim 2, it is characterised in that: further include having following steps；

S5.2, motor drive screw rod (32) rotation is opened, using interval rotation mode, stopped whenever revolving speed reaches after rotation requires Only motor 5-10 seconds, so that slow pressure cleaning notch (34) on screw rod (32) can generate bigger eddy flow and take positioning web plate out of (210) filtration of particulate matters between excessive hole (24).

4. a kind of operating method of filter device as claimed in claim 3, it is characterised in that: further include having following steps；

S5.3, gate valve and block valve (17) when screw rod (32) rotate, in closing cleaning pipe (15).

5. a kind of operating method of filter device as claimed in claim 4, it is characterised in that: further include having following steps；

S6, filter medium need to be inserted to repeatedly using rod iron within every work 3-4 days, so that the undercurrent road that filtering is also formed in it carries out It destroys, filter effect is avoided to decline.
