The water tank is a stainless steel water tank.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is:

1. the five electric valves control the water tank to replenish water, a water level sensor electrically connected with the PLC controller is installed in the water tank, and the PLC controller can control the five electric valves to automatically replenish water to the water tank after corresponding programming.

2. The PLC controller can start backwashing of the filter at regular time through corresponding programming, and when backwashing is performed, the PLC controller controls the electric valve I and the electric valve II to be closed and starts the electric valve III, the electric valve IV and the backwashing pump; through the backwashing, the filter does not need to be disassembled when cleaned, the timing backwashing is favorable for improving the filtering effect of the filter, and the blockage is not easy to cause.

3. In the rainwater season, need filterable water source turbidity higher be, pile up impurity in the filter fast easily for water pressure in the main water pipe increases, and when pressure increased, through water pressure sensor feedback to PLC controller, PLC controller control carries out the backwash of filter in advance, does benefit to the filter effect who improves the filter, and is difficult for causing the jam.

4. The water source water quality filtration and the filter backwashing are automatically controlled by a PLC controller, so that the filtration and backwashing automation is realized.

5. The utility model discloses be applied to the quality of water purification and the swimming pool circulation system quality of water purification etc. of rural mountain water, reservoir, groundwater.
