Abstract
The invention discloses an automatic backwashing device of a filter chamber. The device comprises the filter chamber and a backwashing controller, wherein the inside of the backwashing controller is provided with a signal detection sampling unit, and the signal detection sampling unit is respectively connected with a backwashing water pump, a backwashing blower, an ultrasonic liquid level meter, a water inlet valve, a water discharging valve and an exhaust valve through lines. The signal detection sampling unit leads state signals of all the valves involved in the backwashing process of the filter chamber, the blower and the water pump, differential pressure signals of an upper filter layer and a lower filter layer and liquid level signals of the filter chamber to the backwashing controller. The backwashing process of the filter chamber is automatically controlled according to the collected signals and the preset control information. The process can be automatically carried out, or a backwashing instruction is sent out by a person beside the machine and the backwashing instruction can be given through a remote PLC unit. The automatic backwashing device of the filter chamber can automatically carry out the automatic backwashing process on site or in a central control chamber, the automatic backwashing instruction can be given on an on-site panel, and the process can be controlled through the instruction given remotely.
