Embodiment 1: as shown in Figures 1 to 4, the utility model comprises strainer (2) and contamination depositing trough (3), and strainer (2) is by being screwed together in the pedestal (21) on the water tower (1) and can forming with the filtration core body (22) that pedestal screws togather; Wherein, the apical margin of pedestal (21) is offered water-in (212), and its lateral margin offers a water outlet (211), makes it form a connected state mutually with water-in (212); Filtration core body (22) comprises and is hollow casing (221), its bottom offers a water outlet (213), and install the interior pipe (222) that a Lower Half offers several strip breach (2222) in the inside of housing, should in the processing mode that engages employing high frequency heat involution of pipe and housing, reach the purpose that prevents seepage really.Simultaneously behind interior pipe and housing fit, can form a passage (226) in the Lower Half place of housing, using the water that makes after the filtration can flow out via the breach (2222) of interior pipe, and is following the direction shown in Fig. 3 arrow, flows out through water outlet (213) from passage (226).

The internal ring wall of interior pipe is one stepped, the Lower Half place filling strip filter material (224) of interior pipe, and the central authorities in this filter material form a hollow form duct (2241), and the ladder punishment of pipe institute moulding in this is made as four metafiltration nets (2231), (2232), (2233), (2234) (this filter screen can be the multilayer setting according to actual demand, and the design in aperture can be by the maximum of the superiors, and down dwindle gradually), and at first and second filter screen (2231,2232) and the second and the 3rd filter screen (2232,2233) can insert and put filter material (228) between, and between the 3rd and the 4th filter screen (2233,2234), can place activated carbon (225).This filter screen (2231), (2232), (2233), (2234) engage with the inner tubal wall face simultaneously, but also mat high frequency heat involution technology, and reach tight joint and prevent the effect of seepage.In addition, for guaranteeing the anti-leakage of driving fit more, at the second and the 3rd filter screen (2232,2233) and between the 4th filter screen (2234) and the interior pipe (222), can form respectively and protrude out shape ring gear (2235) and (2226), and this two relative ring gear is crisscross arranged, and makes its interlock and clamping filter material (228) or (224) therebetween mutually.In addition, for promoting housing (221) and interior pipe (222) the involution compactness on affixed more, put a packing ring (227) and can add in the appropriate location that housing engages with interior pipe.

As shown in Figure 4, contamination depositing trough (3) has a joining base (33), this joining base is communicated with second water outlet (211) of strainer (2) by a pipeline (4), and the below of joining base screws togather a storage tank (34), and a pair of lug (32) is extended in the both sides of joining base.On the suitable height wall of storage tank (34), offer a seepage mouth (341), and locate to install additional the thicker filter material of a thickness (342) in this seepage mouth (341).

Strainer (2) connection water inlet pipe (11) and spiral shell are located at the inside of water tower (1), collude on the flange (12) of hanging water tower (1) capping place with hook (31) one ends the both sides of contamination depositing trough (3), the other end colludes on the lug (32) that is hung on contamination depositing trough, makes contamination depositing trough be fixed in the inside of water tower.The installation position of contamination depositing trough is good to be lower than strainer, increases swash impurity and the smooth and easy inflow contamination depositing trough except that having, and also can prevent when flow backwards back when the being full of water phenomenon generation of strainer of contamination depositing trough.

Because being inter-continuation, the water inlet of water tower (1) system replenishes, therefore in the time of under water level is lower than certain limit, enter the additional water of strainer (2) by water inlet pipe (11), can because of first filter material (228) in the filtration core body (22) as yet fully under the wetted state, can stop the additional water that enters, and make most additional water by second water outlet (211) (4) and flow in the contamination depositing trough (3) by the road, when treating that contamination depositing trough forms overflow status, the water inlet that should continue promptly can cause a bigger hydraulic pressure, make water in regular turn via first filter screen (2231), filter material (228), second filter screen (2232), filter material (228), the 3rd filter screen (2233), activated carbon (225), the 4th filter screen (2234) and filter material (224), and flow out from the breach (2222) of interior pipe (222), enter water tower inside through passage (226) from the water outlet (213) of housing (22) again, cause the additional water that enters water tower to be one peace and quiet and be difficult for growing the water storage of vector.In addition, strainer is when filtering water, and the filter material (342) of the water membership seepage mouth (341) in the contamination depositing trough filters, and the water in the contamination depositing trough is slowly passed back in the water tower.When the storage water level in the water tower was increased to desired location, water inlet pipe (11) promptly can stop to replenish the supply of water, and the water in the contamination depositing trough can cause the water level in the contamination depositing trough to be lower than under the seepage mouth because of the seepage of seepage mouth.Yet, this water the impurity (7) of larger particles can be isolated from the surface of first filter screen, and the impurity that enters below first filter screen is the smaller through first filter screen (2231) and filter material (228) time, therefore the obstruction of impurity be can reduce, and the smoothness and the work-ing life of drainage increased.

When the storage water level of water tower is lower than certain limit and when needing to replenish water inlet once more, enter the additional water of strainer by water inlet pipe (11), also can because of filter material (228) as yet fully under the wetted state, impel additional water meeting impulse first filter screen (2231) and the lip-deep impurity of filter material (228) (7) that enter by water inlet pipe, and impurity is flowed in the contamination depositing trough (as the arrow indication) along with water, after contamination depositing trough is overflow status, this water can have bigger hydraulic pressure, and uses water filtration.As for the water in the contamination depositing trough, its inner contained proportion is greater than the impurity of water, can be therefore and precipitation lodges in the contamination depositing trough bottom, and accumulating the water yield and still can be under the slow seepage of seepage mouth (341) in the contamination depositing trough simultaneously, and be lower than below the seepage mouth.

As mentioned above, for each filter the back residual most of impurity (7), but mat additional water inlet impulse next time lodges in the contamination depositing trough impurity.The influence that can not accumulate because of impurity of the smoothness of filtered water simultaneously causes the filter efficacy of strainer to be blocked, and can increase the work-ing life of strainer.In addition, strainer and contamination depositing trough can regularly be pulled down cleaning, and its filter effect is kept in the best condition.

Embodiment 2: as shown in Figure 5, present embodiment and embodiment 1 different be in: this contamination depositing trough (5) extends on the outside wall surface of water tower (6), and this will be convenient to direct dismounting and clean; Simultaneously, for ease of observing and cleaning, the storage tank of contamination depositing trough (51) can be made into transparence.
