The working process of the filter comprises the following steps:
initial state: the unloading pneumatic ball valve 6 is closed, as shown in fig. 1, the lever of the air cylinder 10 is in the lower position, and the backwash liquid inlet valve, backwash liquid outlet valve and air blowing port valve are in the closed state.
One-touch filter:
the valves of the mixed liquor inlet 18 and the filtrate outlet 15 are opened, the feed pump is started, and the mixed liquor to be separated enters the filter cavity, namely the interior of the conical filter cartridge 4, from the mixed liquor inlet 18. The liquid phase passes through the filter cloth 2, enters a space formed by the tapered filter cartridge 4 and the filter housing 3, and flows out from the filtrate outlet 15. The solid phase is intercepted in the filter cavity inside the conical filter cartridge 4 by the filter cloth 2, and along with the progress of the filtering process, the solid phase in the filter cavity is continuously accumulated and increased, and the pressure in the cavity is increased. When the feed pressure reaches the set point, the feed filtration process ends.
The pressing process comprises the following steps: after the filtration is completed, if the liquid content in the solid phase does not meet the requirement, the press may be performed. As shown in fig. 3, at this time, air is introduced from the lower part of the air cylinder 10 to push the upper and lower guide rods 13 to press down, so as to drive the filter cloth 2, reduce the volume of the inner cavity of the conical filter cartridge 4, and squeeze out the residual part of liquid.
And (3) blowing: high pressure air enters the filter cavity of the conical filter cartridge 4 from the air blowing port 17 and flows out from the filtrate outlet 15 through the solid phase. Under the action of jet flow, the high-pressure air takes away part of the solid phase, and the liquid content in the solid phase is further reduced. And stopping blowing when the set blowing time is reached.
And (3) discharging: when the above process is finished, the other valves are closed. And opening the pneumatic ball valve 6, and automatically falling part of the solid phase under the action of gravity. But due to the adhesion between the solid phase and the filter cloth 2, i.e. to the filter cloth 2, even in a very tight bond with the filter cloth 2. At the moment, the air cylinder 10 is required to be ventilated, the upper guide rod 13 and the lower guide rod 13 are pushed, the filter cloth 2 is driven to be pressed down, and the solid phase is forcedly discharged. At this point one filtration cycle ends. When the solid phase in the solid storage box 7 is accumulated to a set quantity, the weighing sensor 8 sends out an alarm signal to remind the solid to be taken.
And (3) back flushing: after several filtration cycles, fine solid particles adhere to the micropores of the filter cloth 2, which affects the filtration effect, and at this time, back flushing of the filter cloth 2 is required. The flushing fluid enters from the back flushing fluid inlet 14, enters the filter cavity through the outer side of the filter cloth 2, takes away fine particles, flows out from the back flushing fluid outlet 16 and flows into the mixed fluid storage tank, and zero discharge is realized.
