As preferably, on regulating block, the one end near pending chamber is provided with guide part, and the width of described regulating block reduces along guide part from the one end away from guide part.
Use said structure, regulating block is placed in the environment of full fluid, there is the probability expanded in it, by the width of regulating block from the one end away from guide part along guide part, the plugging action to adjustment hole of the regulating block after different degrees of expansion can be met, and after changing safety filter element or the process of backwash safety filter element, regulating block remains to be entered in adjustment hole by guide part adjustment hole is played plugging action.
As preferably, the aperture of adjustment hole is reduced along the side near pending chamber from the side away from pending chamber.
Using said structure, when filter membrane blocks, fluid applies enough power to regulating block, and regulating block can quickly extremely be departed from adjustment hole by impact；And when filter membrane is unplugged, regulating block can along at the large aperture of adjustment hole gradually at its small-bore, form the space of a closing in being more beneficial for regulating block is fixed on adjustment hole and with adjustment hole.
As preferably, the size of the filter opening on filter membrane reduces along the flow direction of fluid when filtering.
Use said structure, when when fluid is along backwash, the flow direction of fluid moves (contrary with the motion of the flow direction of fluid when filtering), the flow direction due to fluid during backwash being is along the undersized side of filter opening to the relatively large-sized side of filter opening, therefore its rinse capability is higher, it is more conducive to rinse the impurity on filter membrane remove, the beneficially repetition of the safety filter element of the application, effective use.
As preferably, the outside of described filter membrane and the inwall in filter element chamber are bondd by elastomeric material.
Using said structure, bondd by elastomeric material, its bonding part has certain elasticity, and it has certain anti-impact force, can reduce fluid and break through the probability of its bonding part.
Another object of the present utility model is to provide a kind of filter using described safety filter element, and including the filtrate housing being set in outside safety filter element, described filtrate housing is provided with warning outlet, described warning outlet and warning pipeline connection.
Using said structure, fluid enters safety filter element by fluid inlet, and when filter membrane blocks, fluid passes sequentially through adjustment hole, warns pipeline to warning exit, staff is played warning function, in order to the subsequent treatment timely and effectively of staff；Simultaneously, the fluid filter membrane impulsive force to having blocked is little, this impulsive force is not enough to break through the cohesive force bondd between the inwall in the outside of filter membrane and filter element chamber by elastomeric material, the most untreated fluid will not enter clean fluid collecting region to pollute clean fluid, improves the filter effect of fluid further.
By using technique scheme, have the advantages that
Pending fluid carries out filtering and impurity removing process by the filtration of filter membrane, when filter membrane blocks, regulating block departs under fluid forces from adjustment hole, fluid flows to external environment by adjustment hole, the fluid filter membrane impulsive force to having blocked is little, this impulsive force is not enough to break through the cohesive force bondd between the inwall in the outside of filter membrane and filter element chamber by elastomeric material, and the most untreated fluid will not enter clean fluid collecting region to pollute clean fluid, improves the filter effect of fluid further；
Further, the outside of filter membrane and the inwall in filter element chamber are bondd by elastomeric material, its bonding part has certain elasticity, it has certain anti-impact force, when filter membrane blocks, fluid acts preferentially on regulating block, reduce fluid further to filter membrane and the impact of the bonding part of the inwall in filter membrane and filter element chamber, the probability that minimizing filter membrane breaks through further.
