Description
Technical field
The utility model relates to filter, particularly a kind of backwash accurate filter.
Background technology
Filter is that a kind of filter screen that utilizes is directly tackled impurity in the fluid, removes suspension, particle, reduces system's dirt, the equipment of other follow-up equipment operate as normal in the protection system.
Traditional filter pollutant holding capability is little, is subject to dirt and stops up, and filtration fraction needs frequent disassembly, cleaning, and can't the monitor filter state; In addition, frequently dismantle the destructible filter element, bring economic loss.
In view of this, seek a kind of backwash accurate filter and become pursuing one's goal of these those skilled in the art.
Summary of the invention
The task of the utility model provides a kind of backwash accurate filter, and its has solved the existing in prior technology problem above-mentioned, can filtering overwhelming majority particulates, and its filter area is big, and the rate of filtration is fast.
The technical solution of the utility model is following:
A kind of backwash accurate filter comprises filter cylinder and cover, filter core and medium import and export pipe, and also comprise: the quick-opening device arm connects filter cylinder and cover;
The lower side of said filter cylinder is provided with the medium import, and the upper side of filter cylinder is provided with media outlet, and medium import and media outlet are separately positioned on two opposite sides of filter cylinder, and medium inlet is linked to each other by house steward outside filter cylinder with the media outlet pipe;
Said filter core is several fine filter core, and vertically row are put in cartridge interior, and several fine filter core are fixed on the support that is installed on the filter cylinder inwall, and the bottom surfaces of fine filter core is to the medium import;
Said cover is provided with steam back blow port and drain on the top;
Said filter cylinder bottom is provided with sewage draining exit.
Said cover also is equipped with Pressure gauge on the top, connects drain.
On the house steward between said medium inlet and the media outlet pipe differential manometer is housed.
The backwash accurate filter of the utility model is in order to reach the quality of high-accuracy filtration; Utilize various high-performance filtering materials such as sintered filter core; Reduce the pressure loss when filtering; Through the diversified configuration of various filter cores, be suitable for from gasoline to fluids such as heavy coker gasoline, diesel oil and sewage.
The backwash accurate filter of the utility model is easy to use, and filter area is big, and the rate of filtration is fast; Plugging rate is low, can filtering overwhelming majority particulates, precision can reach 1 μ m; Remarkable to protection follow-up system precision equipment effect, on-the-spot easy for installation, backwash is thorough; Long service life has reduced maintenance cost.
Description of drawings
Fig. 1 is the structural representation of a kind of backwash accurate filter of the utility model.
Reference numeral:
1 is filter cylinder, and 2 is fine filter core, and 3 is the medium import, and 4 is media outlet, and 5 is the quick-opening device arm, and 6 is the steam back blow port, and 7 is drain, and 8 is Pressure gauge, and 9 is sewage draining exit, and 10 is house steward, and 11 is differential manometer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Referring to Fig. 1; The utility model provides a kind of backwash accurate filter, and it is is mainly imported and exported pipe, quick-opening device arm 5, steam back blow port 6, drain 7, Pressure gauge 8, sewage draining exit 9, house steward 10 and differential manometer 11 by filter cylinder 1 with cover, fine filter core 2, medium and forms.
The lower side of filter cylinder 1 is provided with medium import 3, and the upper side of filter cylinder 1 is provided with media outlet 4, and medium import 3 and media outlet 4 are separately positioned on two opposite sides of filter cylinder 1.Medium inlet is connected by house steward 10 in filter cylinder 1 outside with the media outlet pipe.
Quick-opening device arm 5 connects filter cylinder 1 and cover.Cover is provided with steam back blow port 6 and drain 7 on the top.Cover is also installed Pressure gauge 8 on the top, and Pressure gauge 8 connects drain 7.
Filter core is several fine filter core 2, and several fine filter core 2 vertically are listed as and put in filter cylinder 1 inside.Several fine filter core 2 are fixed on the upper and lower support of filter cylinder 1 inside, and upper and lower support is installed in respectively on filter cylinder 1 inwall.The bottom of fine filter core 2 is then in the face of medium import 3.
Use the backwash accurate filter of the utility model, during filtration, along with the aggregation of holding back on the filter core increases; The pressure reduction of importing and exporting between the house steward increases gradually; When pressure reduction reaches setting value, utilize the recoil gas on the pipeline that filter cylinder is carried out backwash, filter residue is washed to sewage draining exit discharge.When pressure reduction returns to original state, filter promptly gets into normal operation.
In sum, the backwash accurate filter of the utility model is easy to use, and filter area is big; The rate of filtration is fast, and plugging rate is low, can filtering overwhelming majority particulates; Precision can reach 1 μ m, and is remarkable, on-the-spot easy for installation to protection follow-up system precision equipment effect; Backwash is thorough, and long service life has reduced maintenance cost.
Certainly; Those skilled in the art in the present technique field will be appreciated that; The foregoing description only is to be used for explaining the utility model; And be not with the qualification of doing the utility model, as long as in the connotation scope of the utility model, all will drop in the scope of the utility model claim the variation of the foregoing description, modification etc.
