Abstract

The utility model relates to a backwashing precision water filter, which comprises an upper cover, a barrel, a lower bottom, supporting legs and a filter device in the barrel. A sewage pipe communicated with the barrel is arranged on a lower mounting plate in the cavity of the lower bottom, a purified water pipe is coaxially arranged in the sewage pipe, the upper end of the sewage pipe is communicated with and arranged on the lower mounting plate, and the sewage pipe is arranged at a random position of the lower mounting plate. A polypropylene (PP) cotton filter pipe for filtering is adopted in the filter, and the PP cotton filter pipe can be used for effectively clearing harmful chemical substances such as suspension, iron, sulfur and the like in water, so that the water treated by the filter can accord with the national standards. The filter has a backwashing function, the filtering effect of the filter cotton core can be effectively improved, and the service life of the filter is prolonged. The filter has the advantages of very simple integral structure, good filtering effect and high filtering efficiency.

Description

The smart water filter of imitating of a kind of back flush type
Technical field
The utility model belongs to water treatment field, relates to filter, the smart water filter of imitating of especially a kind of back flush type.
Background technology
No matter be the surface water, underground water or GEOTHERMAL WATER, all need filter in use that to filter suspension and the harmful substance in the water, filtering employed equipment is filter.Filter all is with filter core water to be filtered, and filter core in use, and filter opening is filtered thing inevitably and stops up, so that the decline of the filter efficiency of filter, and what influence was filtered normally carries out.At present, cleaning way is adopted in the removing of the filtrate that filter core stopped up, need to shut down, take filter apart and clean filter core, the artificial filter core that cleans is wasted time and energy.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of back flush type simple in structure, design science the smart water filter of imitating.
The utility model solves its technical problem and realizes through following technical scheme:
The smart water filter of imitating of a kind of back flush type; Comprise loam cake, cylindrical shell, go to the bottom, leg and the filter in cylindrical shell, the coaxial loam cake that installs on the top of cylindrical shell, coaxial installing gone to the bottom in the bottom of cylindrical shell; Coaxial mounting filtering device in loam cake, cylindrical shell and the formed closed cavity of going to the bottom; It is characterized in that: the structure of said filter is: at the cylinder internal diameter of loam cake position to a upper mounting plate is installed, at the cylinder internal diameter of the position of going to the bottom to a lower installation board being installed, the coaxial parallel installation of upper and lower installing plate; Axially correspondence is uniformly distributed with and is shaped on installation through holes on two installing plates; In the installation through holes of upper mounting plate, be packaged with upper cover, on the lower installation board of corresponding upper cover, be shaped on through hole, common overcoat one filter core on upper cover and the corresponding through hole; The water gap is arranged into to be communicated with the cylindrical shell cavity between the periphery of upper mounting plate and cylindrical shell; The endoporus of filter core is communicated with the cavity of going to the bottom, and is communicated with sewage pipe is installed on the lower installation board in the cavity of going to the bottom with in the cylindrical shell, and perhaps said sewage pipe connection is installed on the cylindrical shell.
And said sewage pipe is installed in the sewage pipe with pure water pipe is coaxial, and the upper end connection of this sewage pipe is installed on the lower installation board.
And said sewage pipe is installed in the optional position of lower installation board.
Advantage of the utility model and beneficial effect are:
1, this filter adopts the filter core of the cotton tube core of PP to filter, and the cotton tube core of this PP can effectively be removed harmful chemicals such as suspension contained in the water, iron, sulphur, and making can National standard through the water of this filter.
2, this filter has backwashing function, can effectively improve the filter effect that filters continuous core, has prolonged the service life of filter.
3, this filter overall structure is very simple, good filtration effect, and filter efficiency is high.

The specific embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
The smart water filter of imitating of a kind of back flush type; Comprise loam cake 5, cylindrical shell 7, go to the bottom 8, leg 10 and the filter in cylindrical shell, installed; Coaxially on the top of cylindrical shell install loam cake through bolt 1, coaxial welding installs and goes to the bottom in the bottom of cylindrical shell, installs leg going to the bottom to be uniformly distributed with; Last covering water inlet is set, is provided with pure water pipe 9 going to the bottom.Coaxial mounting filtering device in loam cake, cylindrical shell and the formed closed cavity of going to the bottom, the structure of this filter is:
At the cylinder internal diameter of loam cake position to a upper mounting plate 4 is installed; At the cylinder internal diameter of the position of going to the bottom to a lower installation board 12 is installed; Upper and lower installing plate is through bolt 3 coaxial parallel installations, and axially correspondence is uniformly distributed with and is shaped on installation through holes on two installing plates, in the installation through holes of upper mounting plate, is packaged with upper cover 2; On the lower installation board of corresponding upper cover, be shaped on through hole; The water gap is arranged into being communicated with the cylindrical shell cavity between the cotton tube core 6 of common overcoat one PP on upper cover and the corresponding through hole, the periphery of upper mounting plate and cylindrical shell, the endoporus connection of the cotton tube core of the PP cavity of going to the bottom.Sewage pipe 11 is installed on the lower installation board in the cavity of going to the bottom, and in the present embodiment, sewage pipe is installed in the sewage pipe with pure water pipe is coaxial, and the upper end of this sewage pipe was installed on the lower installation board with interior connection of cylindrical shell.
In addition, sewage pipe also can be installed in the optional position of lower installation board.
In the filter in the present embodiment, the filtration of water is outside filter core, to enter in the filter core, also can be as required, and above-mentioned filtration fraction is reverse, and the filtration of water is introduced in the filter core, and then water outlet outside filter core.
Present embodiment also can adopt blow-off pipe is recoiled as water inlet pipe; Also can be with blow-off pipe as water inlet pipe; And on cylindrical shell, be communicated with a blow-off pipe again; Perhaps also can on lower installation board, install one with cylindrical shell in the blow-off pipe (above-mentioned two kinds of structures can be omitted in the water inlet pipe that covers) that is connected, its effect and principle are identical with present patent application; Above-mentioned form also can be reverse.
The operation principle of the utility model is:
Water is in water inlet gets into the formed cavity of loam cake, and in the peripheral clearance entering cylindrical shell cavity of upper mounting plate, water filters back entering tube core endoporus through the cotton tube core of PP and flows in the cavity of going to the bottom, and discharges through pure water pipe; Filtered sewage is discharged through sewage pipe.In the time of need carrying out backwash to the cotton tube core of PP, can open recoil pump, recoil water gets in the cavity of going to the bottom through pure water pipe, again from the endoporus of the cotton tube core of PP to the cotton tube core of cylindrical shell cavity direction recoil PP, to improve the filter effect of the cotton tube core of PP.
