Abstract
The utility model discloses a back-flushing water-saving automatic quick pressure adjusting device of a siphon filter. The automatic quick pressure adjusting device comprises a drainage siphon communicated with the siphon filter and an exhaust pipe of an auxiliary drainage device. The exhaust pipe is mounted on the top of the drainage siphon. An automatic exhaust device is mounted on the exhaust pipe. After water in a back flushing pool floods the drainage siphon and the auxiliary drainage device, the air pressure in the auxiliary drainage device increases quickly, and the automatic exhaust device is turned on at first, so that air in the auxiliary drainage device and the drainage siphon communicated with the exhaust pipe is exhausted fully. The start time of the automatic exhaust device is short, meanwhile, a water demand is low so as to help to save the water, and thus, the water treatment efficiency of the siphon filter is improved.
Description
Technical field

3/ h, the filter tank is comprised of six lattice, be 12 hours filter cycle, in the recoil wash pool, discharge siphon 1 is installed, discharge siphon 1 is connected with auxiliary discharge siphon 5 by exhaust tube 2, each recoil wash pool also is provided with the pressure siphon pipe 9 of connection, be used for forcing to bleed, and the exhaust tube 2 of forcing siphon pipe 9 to be communicated with on each discharge siphon 1, when the water level of any one lattice of filter tank rises to when flooding discharge siphon 1, air in the discharge siphon 1 is constantly compressed with the water level rising, forms intraductal atmospheric pressure.
According to The Ideal-Gas Equation:
PV=NRT (constant), i.e. P
1V
1=P
2V
2
P
1: the pressure when begin new filter cycle is identical with atmospheric pressure;
V
1: press duct length and calculate, as get 6.0 meters;
P
1: maximum pressure in the pipe, overpressure during near siphon;
V
2: press duct length and calculate, as get 4.0 meters;
The interior maximum pressure of pipe can be calculated and 0.15 MPa can be reached, only depending on auxiliary discharge siphon time that needs of bleeding is 50 minutes, force siphon pipe to be bled if open simultaneously, make and force siphon pipe and auxiliary discharge siphon to be moved simultaneously, the time that needs is 25 minutes, and the draining that this shows dual mode time of bleeding is longer, through actual metered, each draining is bled and is caused the siphon backwash until form negative pressure in the drainpipe, and needing the water yield is 15m
3, waste water source phenomenon is serious.
