FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of water flow during the back washing operation of the present invention.
In the figure: the device comprises a clean water tank 1, a water outlet 101, a clean water bin 102, a filter tank 2, a filter plate 201, a three-way connecting pipe 202, an electric valve 3, a pressure sensor 4, an operation control box 5, a data cable 6, a washing water outlet pipe 7 and a raw water inlet pipe 8.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
As shown in fig. 1, an automatic flushing device for a filter tank of a water purifying device comprises a clean water tank 1, a filter tank 2, an electric valve 3, a pressure sensor 4, an operation control box 5, a data cable 6 and a flushing water outlet pipe 7, wherein the filter tank 2 which is suspended and fixed with the clean water tank 1 is arranged at the lower end of a clean water cabin 102 of the clean water tank 1, and a water outlet 101 is arranged at the upper end of one side of the clean water tank 1; the lower end of the filter 2 is provided with a filter plate 201 which is communicated with the clean water bin 102; an external raw water inlet pipe 8 penetrates into the clean water tank 1, transversely penetrates through the upper end of the filter tank 2 and is connected with a flushing water outlet pipe 7, the flushing water outlet pipe 7 is connected with the other side extending out of the clean water tank 1, and the water outlet end is connected with an electric valve 3;
the raw water inlet pipe 8 in the clean water bin 102 is connected with a three-way connecting pipe 202, and the other end of the three-way connecting pipe 202 is communicated with the inner cavity of the filter chamber 2; the outer end of the water purification tank 1 is provided with a pressure sensor 4, the pressure sensor 4 is connected with a data lead and a data cable 6, the data lead is connected with the inner cavity of the filter tank 2, and the other end of the data cable 6 is in signal communication with the electric valve 3; the operation control box 5 is provided with a data cable 6 which is communicated with the electric valve 3.
The utility model discloses in using, pressure sensor detects and leads to the little filtering pond internal pressure of play water to rise when being greater than the setting value because of the reduction of dirt accumulation filter plate permeability, gives the motorised valve to the signal feedback, and the motorised valve sends the operation control box in step, and the water discharge in the filtering pond is arrived to the automatic function of washing the filtering pond to the motorised valve of opening the motorised valve and washing the outlet pipe.
