The corrosion-resistant sea water filter device of the New Marine that the utility model is announced is made up of end cover 1, the asymmetric high strength honeycomb ceramic filter core 2 of L type and housing 3 three parts; Wherein, end cover 1 is made up of along arc-shaped end plate 4, annular sealing strip 5 and bolt hole 6 band; The asymmetric high strength honeycomb ceramic filter core 2 of L type is installed bracing frame 8 and is connected draw-in groove 9 by ceramic honey comb filter plate 7, I shape and forms; Housing 3 is made up of sealing edge 10, sea intake 11, seawer outlet 12, sewage draining exit 13, sewage draining exit seal cover 14 and handle 15, and sewage draining exit 13 is welded on housing 3 bottoms, and sewage draining exit seal cover 14 is enclosed within on the sewage draining exit 13; End cover 1 fuses through being connected draw-in groove 9 with the asymmetric high strength honeycomb ceramic filter core 2 of L type; Vertically be placed in the housing 3; Utilize bolt hole 6 that annular sealing strip 5 is connected with sealing edge 10, thereby make end cover 1 and closely be connected, form enclosure space with housing 3.
Two ceramic honey comb filter plate 7 length are different in the asymmetric high strength honeycomb ceramic filter core 2 of said L type, and the angle of two ceramic honey comb filter plates 7 is 120 °, corresponding sea intake 11 center lines of interior angle center line, corresponding seawer outlet 12 center lines of exterior angle center line; Said ceramic honey comb filter plate 7 is a 10mm thick plate-like structure, takes embedded method, is installed in I shape and installs on the bracing frame 8, is convenient to ceramic honey comb plate fast assembling-disassembling, replacing, and top is connected fixing with housing seal lid bottom.Asymmetric L type structure and filter opening and water (flow) direction angle make current in L type concave surface, form rotating vortex, automated cleaning cartridge surface impurity, and impurity is deposited in the sewage draining exit 13 automatically.
Among the present invention with the place of contact with sea water; Comprising that short tube that end cover 1, housing 3 are connected with each and flange all will spray to hang moulds that thick anti-of one deck 1mm washed away, the aging-resistant macromolecular material; Except that realization self decay resistance, also prevent connecting line generation electrochemical corrosion.
The beneficial effect that the utility model can bring is:
(1) effective purifying sea water is realized the filtering function requirement, and the asymmetric high strength honeycomb ceramic filter core 2 of L type is applicable to the requirement of 50-200 μ m single layer filter, and the seawater resistance is equal to same holes purpose metal screen;

Description of drawings
Fig. 1 is the overall schematic of the utility model.
Fig. 2 is the end cover and the asymmetric high strength honeycomb ceramic filter core of the L type structural representation of the utility model.
Fig. 3 is the housing lower end structure sketch map of the utility model.
Among the figure, 1 end cover, the asymmetric high strength honeycomb ceramic filter core of 2 L types, 3 housings, 4 arc-shaped end plates, 5 annular sealing strips, 6 bolts hole, 7 ceramic honey comb filter plates, 8 I shapes are installed and are supported, 9 connection draw-in grooves, 10 seal edges, 11 sea intakes, 12 seawer outlets, 13 sewage draining exits, 14 sewage draining exit seal covers, 15 handles.
The specific embodiment
Each part of the utility model is: the asymmetric high strength honeycomb ceramic filter core of end cover 1, L type 2, housing 3.
End cover 1 is made up of along arc-shaped end plate 4, annular sealing strip 5 and bolt hole 6 band; The asymmetric high strength honeycomb ceramic filter core 2 of L type is installed bracing frame 8 and is connected draw-in groove 9 by ceramic honey comb filter plate 7, I shape and forms; Housing 3 is made up of sealing edge 10, sea intake 11, seawer outlet 12, sewage draining exit 13, sewage draining exit seal cover 14 and handle 15; End cover 1 fuses through being connected draw-in groove 9 with the asymmetric high strength honeycomb ceramic filter core 2 of L type; Vertically be placed in the housing 3 afterwards; Utilize bolt hole 6 that annular sealing strip 5 is connected along 10 with sealing; Thereby make end cover 1 and closely be connected with housing 3, form one and seal integral body, the while is two chambeies before the asymmetric high strength honeycomb ceramic filter core of L type 2 both sides form filter and after filtering.In addition, end cover 1 all applies one deck macromolecular material with housing 3 surfaces externally and internallies, and metal material and seawater are isolated.
The implementation procedure of the corrosion-resistant self-cleaning function of the utility model sea water filter device peculiar to vessel is following: seawater is inner through sea intake 11 accesss to plant under pressure; Turn back when advancing to ceramic honey comb filter plate 7 and pass through ceramic honey comb for hexagonal angle; Impurity in the seawater is blocked in the filter ante-chamber; Seawater after the filtration gets into the filter back cavity, offers terminal device through seawer outlet 12.Because the asymmetric high strength honeycomb ceramic filter core 2 of L type is a L type unsymmetric structure; And ceramic filter opening becomes 120 ° of angles with the incident seawater; Seawater forms rotating vortex at the filter ante-chamber under hydrodynamism; The eddy current center is near sewage draining exit, and eddy current washes away ceramic honey comb filter plate 7 surfaces automatically and forms automatic cleaning action, and impurity progressively deposits in the sewage draining exit 13 under the gravity effect.The equipment working clearance capable of using during desilting, sewage draining exit end cap lock handle 15 is mentioned and is taken off sewage draining exit seal cover 14, the seawater that retains in the housing will flow out through sewage draining exit, the impurity in the sewage draining exit seawater eroding next and discharge, accomplish the desilting function.Because end cover 1 is coated with macromolecular material with surface of shell, seawater and metal material is completely cut off open the corrosion-resistant function of implement device.
In sum, the utility model is effective purifying sea water not only, harm such as can avoid also that terminal device is avoided stopping up, wearing and tearing, cooling are bad.In addition, its simple in structure, highly versatile self possesses automatically cleaning and corrosion-resistant function, has long service life and characteristics such as simple to operate, has broad application prospects.
