Abstract
The utility model discloses a back flush sandstone filtration ware, including casing (1), inlet tube (2), outlet pipe (9) and grit baffle (8) to, become to go up cavity and down cavity with separating in the casing by grit baffle (8), be equipped with on casing (1) of last cavity be equipped with on inlet tube (2) and flange A (5) corresponding flange B (21), inlet tube (2) connect on casing (1) of last cavity department through flange A (5) and flange B (21). Compared with the prior art, the utility model discloses the inlet tube passes through flange joint on the casing, does not need professional maintenance personal can conveniently maintain yet, can improve the service life of filter greatly.
Description
Technical field
This utility model relates to a kind of backwash sand filter.
Background technology
Filter, particularly backwash sand filter used by drip irrigation and spray irrigation in current water-saving agriculture, has simple in construction, and device fabrication cost is low and the advantage of good filtration effect, commercially occupies proportional very greatly.
Such as the filter disclosed in Chinese patent CN2451211Y, CN2761243Y, 01233801.X, CN203123637U, CN202343008U.
Filter is separated into upper and lower two cavitys typically via arranging a dividing plate in mesh-like in the housing by the type filter, then lays sandstone filter course on dividing plate and constitutes filtering ponds.Being water inlet pipe above filtering ponds, generally this water inlet pipe also functions simultaneously as backwash outlet pipe, therefore it is required that of a relatively high.
Water inlet pipe above current filtering ponds is all directly weld or be fixedly connected on filter housings, in maintenance very inconvenient, particularly when under water inlet pipe damaged condition, except changing except specialized maintenance personnel, whole filter is caused to be difficult to keep in repair and scrap in a lot of situations, very uneconomical.
Summary of the invention
The purpose of this utility model be to provide a kind of need not the backwash sand filter that also can maintain easily of specialized maintenance personnel.
The purpose of this utility model is realized by following structure: include housing (1), water inlet pipe (2), outlet pipe (9) and sandstone dividing plate (8), and, upper chamber and lower chambers will be separated in housing by sandstone dividing plate (8), it thes improvement is that: the housing (1) of described upper chamber is provided with described water inlet pipe (2) and is provided with the adpting flange B (21) corresponding with adpting flange A (5), described water inlet pipe (2) is connected on the housing (1) at place of upper chamber by adpting flange A (5) and adpting flange B (21).
Further, above-mentioned upper chamber is preferably provided with water inlet pipe support (22), to support water inlet pipe (2), keeps water inlet pipe (2) stablizing in upper chamber.
Further, above-mentioned water inlet pipe support (22) is preferably a body, and described water inlet pipe (2) is movably connected on body, and described body is connected with housing by link A (23).
Further, the lower chambers that above-mentioned outlet pipe (9) is anterior is preferably provided with well strainer (7), and lower chambers outlet pipe (9) place is provided with adpting flange C (92), outlet pipe (9) is provided with adpting flange D (91) corresponding for adpting flange C (92), and described well strainer (7) is connected on outlet pipe (9) by adpting flange D (91).
Yet further, above-mentioned lower chambers is preferably provided with well strainer support (71), to support well strainer (7), keeps well strainer (7) stablizing in upper chamber.
Further, above-mentioned well strainer support (71) is preferably a body, and described well strainer (7) is movably connected on body, and described body is connected with housing by link B (72).
Compared with prior art, this utility model water inlet pipe passes through Flange joint on housing, it is not necessary to specialized maintenance personnel also can maintain easily, and can be greatly improved the service life of filter.
