Abstract
The utility model relates to a structure of a rod-shaped primary filter. Filter cylinders, at the bottom parts of which filter screens are fixed, are arranged in a casing in a layered way, the filter cylinders are mutually sheathed, the height of each cylinder port is identical. Sealing rubber rings and press plates are arranged on the filter cylinders; meshes of each filter cylinder are denser gradually from top to bottom, and activated carbon granules are filled in each filter cylinder. The utility model has the identical shape with a rod-shaped water filter, and has the advantages of thorough filtration and removal of impurities and abnormal flavor and convenient maintenance.
Description
The utility model belongs to water treatment facilities, particularly relates to a kind of preliminary filter.
Use the water filter that supplies group to use of hollow fiber ultrafiltration membrane, usually give filter and ultrafilter two parts are formed by bar-shaped, find in the use, give filter to be stopped up by impurity such as the suspension in the water, corrosion things easily and influence water yield, particularly in that to contain the relatively poor situation of water quality such as silt, algae even more serious.
The purpose of this utility model provides a kind of bar-shaped preliminary filter that above-mentioned ultra-clean water filter uses that is fit to, so that its water yield under complicated water condition is unaffected.
Above-mentioned purpose is realized by following technical scheme:
In the preliminary filter housing, layering is provided with the fixedly filter cylinder of filter screen of bottom, each filter cylinder mutual sheathing, and nozzle height unanimity, the O-ring seal of being fixed with the friction tight annular pressing plate of preliminary filter housing is housed on it, the mesh of each filter cylinder filter screen is gradually close by dredging from top to bottom, in each filter cylinder granular active carbon is housed.
Be shaped on the boss or the carriage of supporting upper strata filter cylinder in each filter cylinder.
Further specify this structure with drawings and Examples below.
Accompanying drawing 1, the utility model structural representation.
Drawing explanation: loam cake 1, housing 2, annular pressing plate 3, O-ring seal 4, filter cylinder 5, filter screen 6, boss 7, active carbon 8, lower cover 9.
Embodiment as shown in the figure, except that filter screen (6), all adopt stainless steel material, each filter cylinder (5) rolling has boss (7), this example is provided with four metafiltration tubes, each filter cylinder is suit successively from top to bottom, barrel is in contact with one another, the height of boss and filter cylinder matches, and the nozzle of each filter cylinder is evened up, for preventing directly to let out down from outer barrel from the water that loam cake (1) water inlet is introduced, O-ring seal (4) is housed on each nozzle of evening up, and fixing by annular pressing plate (3), each filter screen (6) is a nylon braid, fixes by packing, mesh diameter is 0.25 from top to bottom successively, 0.14,0.06,0.03 millimeter, each metafiltration tube is all filled active carbon (8).No matter showing at the beginning of what water quality is by four metafiltration tubes, test filters, acrobatics in the equal thoroughly filtering water, and can guarantee water yield.Graininess activity (8) also can effectively be adsorbed peculiar smell.The preliminary filter of this structure is convenient to regularly replace active carbon or the impurity of holding back, easy accessibility are removed in layering.
The utlity model has impurity in the profile consistent with the drainage rod and the thorough filtering water And peculiar smell, the remarkable advantage of being convenient to safeguard.
Claims (2)
1, a kind of preliminary filter of ultra-clean water filter, formed by housing, loam cake, lower cover, it is characterized in that: layering is provided with the fixedly filter cylinder of filter screen of bottom in the housing, each filter cylinder mutual sheathing, and nozzle height unanimity, the O-ring seal of being fixed with the friction tight annular pressing plate of housing is housed on it, and the aperture of each filter cylinder filter screen is gradually close by dredging from top to bottom, in each filter cylinder granular active carbon is housed.
2, preliminary filter as claimed in claim 1 is characterized in that: the boss or the carriage that are shaped on supporting upper strata filter cylinder in each filter cylinder.
