Description
Technical field
The utility model relates to a kind of unpowered full-automatic differential filter device, belongs to the water purification filtration art.
Background technology
At present, the water purification filter mainly is divided into two types both at home and abroad, and first kind is hydrocone type gravity valveless filter, and second kind is differential filter.Second kind is divided into again manually and automatic two kinds of structures; First kind relies on siphon principle can realize full-automatic filtration, and second kind is transferred to power drive with pressure difference signal and also can realizes full-automatic filtration.
First kind of hydrocone type gravity valveless filter, vertical installation, pending water gets into the filter tank through water pipe and filters back entering water tank from top to bottom through filtering layer, and water tank is full of the back and gets into clear water reserviors through outlet pipe.Filtering layer is constantly held back suspension; Cause resistance to increase, impel the water level in the siphon pipe constantly to raise, when water level reaches the auxiliary siphon tube mouth of pipe; Water falls from this pipe;,, just siphonage takes place and make water carry out backwash through filtering layer to filtrate from bottom to top when vacuum reaches certain value so as to taking away the air that siphon descends through exhaust tube.When siphon destructing tube was reduced in the flush box underwater, air got into siphon pipe, destroyed siphonage, and backwash finishes, and filtration restarts.The subject matter that this type of filter exists: the one, backwash is for carrying out from bottom to top, and the impurity that proportion is bigger in the former water can't be discharged, and directly influences filter efficiency; The 2nd, backwash from bottom to top, impurity content less water in filter course top is discharged earlier, and impurity content more water in bottom can't all be discharged, and causes that the backwash water yield is big, the backwash weak effect; The 3rd, in case appearring in siphon pipe, little leakage siphon destroyed, filter is with entirely ineffective.
Second kind of differential automatic filter operation principle is: pending water gets into filter by water inlet, and the impurity in the water is deposited on the filter course, produces pressure reduction thus.Detect pressure reduction numerical value through pressure test device; When pressure reduction reaches setting value; Pressure difference signal converts electrical signal transfer into and gives electric controller, and electric controller control water-supply valve and blowoff valve clean filter course, cleans when finishing; System returns to its original state automatically, begins to get into the next operation of filtering.Differential manual filter work principle of filter is identical, manually controls according to the pressure reduction video data and carries out backwash.The subject matter that this type of automatic filter exists is that complex equipments, fault rate are high, investment is big, needs consumption of power.Manual filter is had relatively high expectations to operating personnel's, and labour intensity is big.
