Description

Fine filter

Technical field

The utility model belongs to water treatment, especially a kind of employed fine filter of GEOTHERMAL WATER that recharges.

Background technology

The development and use of GEOTHERMAL WATER are in the ascendant, have satisfied the demand that people pursue higher quality of life.GEOTHERMAL WATER from underground be drawn into pumping plant by terrestrial heat pump after, use through the user, the GEOTHERMAL WATER after the use is recharged underground according to the national regulation needs, to guarantee the water level of GEOTHERMAL WATER.At present, through the recharging of GEOTHERMAL WATER after using is to take direct recycling mode basically, can not filter contained a large amount of suspensions and harmful substance in the GEOTHERMAL WATER after using, do like this, not only easy blocking pipeline, and can produce the secondary pollution problem, thereby directly influence the quality of GEOTHERMAL WATER resource to underground GEOTHERMAL WATER resource.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of design science rationally, can be to recharging the fine filter that harmful substance in the GEOTHERMAL WATER is carried out fine filtering.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of fine filter, single unit system comprises loam cake, cylindrical shell, go to the bottom, leg and filtration fraction, wherein, the top of loam cake is provided with water inlet, the bottom of going to the bottom is provided with pure water pipe, leg is packed in the bottom of going to the bottom, loam cake installs by bolt is coaxial with cylindrical shell, go to the bottom and cylindrical shell is that coaxial welding installs, the water gap is arranged into to be communicated with the cylindrical shell cavity between the periphery of upper mounting plate and cylindrical shell, at loam cake, coaxial installation filtration fraction in the cylindrical shell and the formed closed cavity of going to the bottom, it is characterized in that: the structure of filtration fraction is: be communicated with the cylindrical shell cavity on the cylindrical shell and also be provided with an effluent outfall, 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 is installed, last, the axially corresponding uniform installation through hole that is shaped on following two installing plates, in the through hole of upper mounting plate, be packaged with upper cover, through hole at lower installation board is the projective table type through hole, the cotton tube core of common overcoat one PP of corresponding upper cover and projective table type through hole, the endoporus of the cotton tube core of PP is communicated with the cavity of going to the bottom.

And, a recoil tube is installed on described pure water pipe.

And upper and lower installing plate is installed by the bolt coaxial positioning.

Advantage of the present utility model and beneficial effect are:

1. this fine filter adopts the cotton chimney filter core of PP to filter, and the cotton chimney filter core of this PP can effectively be removed harmful chemicals such as suspension contained in the GEOTHERMAL WATER, iron, sulphur, makes recharging GEOTHERMAL WATER and can meet national standard through this filter.

2. this fine filter has backwashing function, can effectively improve the filter effect and the service life of filtering continuous core.

3. this fine filter overall structure is very simple, and good filtration effect can effectively be removed the harmful substance of recharging in the GEOTHERMAL WATER, the water quality of GEOTHERMAL WATER is recharged in assurance, avoiding the obstruction to the geothermal reinjection pipeline, is the indispensable equipment that the underground heat pumping plant recharges, and can effectively promote the level of comprehensive utilization of GEOTHERMAL WATER.

The specific embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of fine filter is that the underground heat pumping plant recharges in the equipment, and single unit system comprises loam cake 8, cylindrical shell 9, go to the bottom 11, leg 12 and filtration fraction.Wherein, the top of loam cake is provided with water inlet 5, and cylindrical shell is provided with effluent outfall 10, and the bottom of going to the bottom is provided with pure water pipe 14, and recoil tube 13 is installed on this pure water pipe, and leg is packed in the bottom of going to the bottom.Loam cake and cylindrical shell be by bolt 1 coaxial installing, and goes to the bottom and cylindrical shell is that coaxial welding installs.Coaxial installation filtration fraction in loam cake, cylindrical shell and the formed closed cavity of going to the bottom, the structure of this filtration fraction is:

At the cylinder internal diameter of loam cake position to a upper mounting plate 4 is installed, in the cylindrical shell of position of going to the bottom, be welded with ring platform (not having label), on this ring platform, a lower installation board 15 radially is installed by bolt 16, upper and lower installing plate passes through bolt 3 and centre bolt 7 coaxial installations, the axially corresponding uniform installation through hole that is shaped on two installing plates.Being packaged with upper cover 2 in the through hole of upper mounting plate, is the projective table type through hole at the through hole of lower installation board, the cotton tube core 6 of common overcoat one PP of corresponding upper cover and projective table type through hole.Have between the periphery of upper mounting plate and cylindrical shell that into the water gap is to be communicated with the cylindrical shell cavity, the endoporus of the cotton tube core of PP is communicated with the cavity of going to the bottom.

Operation principle of the present utility model is: recharge GEOTHERMAL WATER in water inlet enters the formed cavity of loam cake, and enter in the cylindrical shell cavity through the peripheral clearance of upper mounting plate, recharge and enter the tube core endoporus after GEOTHERMAL WATER is filtered through the cotton tube core of PP and flow in the cavity of going to the bottom, be discharged to the underground pipeline that recharges through pure water pipe; Filtered sewage is discharged through effluent outfall.In the time of need carrying out backwash to the cotton tube core of PP, can open recoil pump, recoil water enters 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.
