The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all utilize the innovation and creation of the utility model design in the column of protection.
As shown in Figure 1, the preposition backwash filter includes top cover 1 and the filter cylinder being detachably connected with top cover 12 and sets
Filter core 3 in filter cylinder 2.The two sides of top cover 1 are coaxially collinearly arranged in water inlet 4 and water outlet 5.Top cover 1 is with a closed top
Cylindrical shape, the internal internal chamber wall by annulus shape are separated into inner cavity 11 spaced apart from each other and exocoel 12, and water inlet 4 is to be passed through
Round pipe in inner cavity 11, water outlet 5 are the round pipe being passed through in exocoel 12.Water inlet 4 and water outlet 5 and top cover 1 are poly- third
Alkene material is integrally formed by mold.
Copper sheathing 41, the i.e. outer circle of copper sheathing 41 are equipped in the intersection gear shaping of water inlet 4 and water outlet 5 and 1 outer wall of top cover
It is evenly distributed with gear shaping on circumferential surface, the hole inner wall circumference that top cover 1 installs the copper sheathing is provided with several corresponding inserted tooth slots, passes through
Gear shaping is embedded in inserted tooth slot and copper sheathing 41 is fixed on top cover 1.It is threaded on 41 inner wall of copper sheathing, is connected by copper sheathing 41
Union elbow 43.Copper sheathing 41 is more preferable compared to 1 intensity of top cover made of polypropylene material, and processing screw thread is more convenient.Quadrature tube connects
First 43 change water route direction, facilitate and this filter is connected in existing water pipe.
The lower end of top cover 1 is machined with external screw thread, which is threadedly coupled with the nut 23 being actively socketed on filter cylinder 2.
There is the boss matched with the step surface 24 on filter cylinder 2 in the bottom end of nut 23, and the internal diameter of the boss is less than screw thread on nut 23
Internal diameter.Have uniformly at intervals on the outer circumference surface of nut 23 it is several along axial strias, when can be manually rotated nut 23 to increase
Frictional force.
Filter cylinder 2 is provided with the circumference boss that outer diameter is greater than filter cylinder body diameter close to top, and the bottom surface of the boss is platform
Terrace 24.Nut 23 is inserted in from the bottom end of filter cylinder 2, is limited nut 23 by step surface 24 and is continued, nut mobile to 1 direction of top cover
The external screw thread on internal screw thread and top cover 1 on 23 cooperates, and filter cylinder 2 is fixedly connected with top cover 1.
Filter cylinder 2 is the closed cylinder of top open bottom.21 He of inner convex platform is coaxially arranged in the inside bottom surface of filter cylinder 2
Outer lug boss 22, inner convex platform 21 and outer lug boss 22 are round ring boss, and inner convex platform 21 is higher than outer lug boss 22.Inner convex platform 21 surrounds
Bottom cylindrical face on be provided with sewage draining exit 6.
Filter core 3 includes skeleton 31 and the strainer 32 being fixed on skeleton 31.Strainer 32 selects different pore size as needed
Strainer, skeleton 31 are used to support strainer 32.The both ends of skeleton 31 have been connected through a screw thread seal receptacle 34, pass through seal receptacle 34 and bone
Filtering frame 33 is pressed in by the screw-threaded coupling between frame 31 enables filtering frame 33 fall big contaminant filter between the two, reduces
