BRIEF DESCRIPTION OF DRAWINGS

[0013] Fig. 1 The utility model of structure schematic drawing is provided;

[0014] Fig. 2 The utility model of local structure schematic drawing is provided. DETAILED DESCRIPTION

[0015] As Figs. 1-2 shown, a rural drinking water pretreatment filtering device, including the shell 1 that the chamber is formed in the hollow inside, the shell 1 upper portion is equipped with the water inlet and water inlet pipe 2 of access chamber, the shell 1 again is equipped with the hollow interlayer 3 in chamber one side, the shell 1 lower portion is equipped with the water outlet and water outlet pipe 4 of access interlayer 3, the water inlet pipe 2 is equipped with booster device 5. The design of interlayer 3 is favorable to set multiple water outlets in the longitudinal direction, improve the water outlet efficiency of pretreatment, and also can store water in advance when not using water. The booster device 5 of water inlet pipe 2 can not be opened in daily life, and in this embodiment, it is mainly used in the case of insufficient water pressure, such as when the number of simultaneously used water points is relatively large and must be guaranteed. Since the design does not rely too much on water pressure, the booster device 5 only needs a smaller power type, which can already meet the daily use needs.

[0016] The chamber is provided with a filtering assembly and a guiding assembly. The filtering assembly comprises upper and lower filtering plates 6 and 7 which are arranged in parallel and horizontally inclined. The upper and lower filtering plates 6 and 7 are each provided with filtering grooves 8 for filtering out particulate impurities. The filtering grooves 8 of the upper and lower filtering plates 6 and 7 are arranged in a staggered manner in the longitudinal direction. The filtering grooves 8 of the upper filtering plate 6 are distributed on the upper side of the center line, and the filtering grooves 8 of the lower filtering plate 7 are distributed on the lower side of the center line. The chamber wall is provided with a hydrophobic device 9 which communicates with the interlayer 3 near the lower side of the upper and lower filtering plates 6 and 7. Each filtering assembly comprises at least an upper filtering plate 6 and a lower filtering plate 7, so that stones and large particles can gradually fall to the bottom layer of the chamber through the filtering grooves 8. In this embodiment, even if the water quality is relatively turbid and the uppermost filtering assembly is completely disabled, the lower filtering assembly can still function. Impurities are trapped or accumulated and fall in a staggered manner during the filtering process, and finally most of them are concentrated near the sewage outlet. In order to fully utilize the space, the guiding assembly is arranged to guide the water containing impurities back to the starting side, which is beneficial to the clean water flowing out from the other side. It should be noted that the embodiment is best used for clean water containing only sand and stones, and is less effective for water mixed with a large amount of mud. However, after coarse filtering, the water can be further filtered by other means, which can also have a certain pretreatment effect.

[0017] The guiding assembly comprises a guiding plate 10 and a guiding seat 11. The chamber is provided with a sewage valve 12 on one side of the lower part. The guiding plate 10 is inclined relative to the horizontal and guides the flow to the side of the sewage valve 12. The guiding seat 11 has a flow guiding arc surface which guides to the side of the sewage valve 12. The sewage valve 12 requires a relatively wide and convenient sewage outlet for operation, and the opening and closing are simple and the sealing effect is good. The flow guiding arc surface is beneficial to the concentration of impurities and facilitates cleaning. The filtering assembly is arranged in at least two groups in the longitudinal direction. The guiding plate 10 is arranged between the filtering assemblies, and the inclination direction of the filtering assembly is opposite to that of the guiding plate 10. The more filtering assemblies are arranged, the more impurities are retained, and the water outlet efficiency of each layer is higher.

[0018] The filtering assembly and the guiding plate 10 are connected by a hinged assembly. The hinged assembly comprises a fixed seat 13, a cover plate 14, a bolt 15 and a nut 16. The fixed seats 13 are arranged in pairs and are spaced apart. The cover plate 14 has a central through sleeve 17 at both ends. The sleeve 17 is arranged between the fixed seats 13. The bolt 15 is threadedly connected to the nut 16 after penetrating the fixed seat 13 and the sleeve 17. This connection method is convenient for disassembly and removal. During actual production and processing, the fixed seat 13 can be directly welded to the specified plate or wall.

[0019] The upper filter plate 6 and the lower filter plate 7 are separated into a short plate part 18 and a long plate part 19 by a filter groove 8, the short plate part 18 at the upper filter plate 6 is higher than the height of the long plate part 19, and the short plate part 18 at the lower filter plate 7 is lower than the height of the long plate part 19. The distance between the hydrophobic device 9 and the lower side of the short plate part 18 of the lower filter plate 7 is smaller than the distance between the hydrophobic device 9 and the lower side of the long plate part 19 of the upper filter plate 6. Fine particle impurities are likely to accumulate at the long plate part 19 of the upper filter plate 6, so the hydrophobic device 9 is arranged higher at this position, and a part of the impurities can be intercepted and slowly seep out of the water to the interlayer 3. The short plate part 18 makes the water flow or the impurity movement speed not high, and can quickly screen out large mass sand and other impurities. The long plate part 19 is more used for intercepting fine impurities in a long distance, and the effect of the lower filter assembly or the long plate part 19 is more obvious in the embodiment. It should be pointed out that the hydrophobic device 9 generally adopts a component with a relatively precise filter screen, so that even if the uppermost hydrophobic device 9 is blocked, it is still beneficial to water accumulation and finally overflow, fall and filter.

[0020] The booster device 5 is an electric pump with a manually opened and closed valve, and low power can meet the use requirement, and the booster device 5 is not described and limited too much here. The cut-off valve 21 is further arranged at the water outlet pipe 4, so that the water inlet and outlet can be cut off for maintenance. The equalizing valve 20 for balancing the internal and external pressure difference is further arranged at the upper part of the shell 1, which can effectively prevent the relative negative pressure in the pipe from obviously affecting the water use, and ensure smooth and stable water outlet.

[0021] In the description of the utility model, it should be explained that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model, at the same time, the basic principle, main characteristics and advantages of the utility model are shown and described above, and the skilled in the art should understand.
