Backwash mode；When material intake line (14) backwash mode, pressure vessel is in any one supply unit (8) and is taken out very
When the empty stage starts, charging Pneumatic gate valve (8-8) and aerating pneumatic ball valve (8-12) are opened, continues 3 ~ 9 seconds, is then shut off charging
Pneumatic gate valve (8-8) and aerating pneumatic ball valve (8-12) operate 2 ~ 4 achievable material intake line (14) recoils repeatedly；Object
When expecting discharge tube (13) backwash mode, when any one supply unit (8) is in pressure vessel vacuumizing phase and starts,
It opens discharge Pneumatic gate valve (8-7), continues lasting 3 ~ 9 seconds, be then shut off discharge Pneumatic gate valve (8-7), operating 2 ~ 4 times repeatedly can
Realize discharge of materials pipeline (13) recoil.
10. the method for discharging pollution of vacuum sewerage vertical hoisting system according to claim 8, it is characterised in that: the step
In S1-S4, reclamation pattern is opened according to material situation；When reclamation pattern, additive pneumatic ball valve (8-9) need to be opened, to pressure
Modifying agent or lubricant are added in container, and material is improved.
