Between space be divided into the equal chamber 7 of multiple cross-sectional areas, segmentation in this way filtering, each 7 water of chamber is uniform, can be promoted
The effect and efficiency of filtering, chamber 7 is interior to fill stainless steel filter core, and design in this way makes entire two-stage filter one
A entirety, sound construction；Meanwhile stainless steel filter core has good strainability, filtered underground water, which is able to satisfy system, to be made
With requiring, corrosion resistance, heat resistance, resistance to pressure, wearability are good, are able to satisfy severe underground environment, core stomata uniformly, it is accurate
Filtering accuracy, the flow of unit area is big, can improve the efficiency of essence worry, meet system water demand, can be with after cleaning
It reuses, it is free of replacement, it economizes on resources, reduces cost；Two-stage filter is mainly by 9 He of permeable hole being located on 5 tube wall of outer tube
Two layers of filter core filtering in chamber 7, left and right adjacent two column of permeable hole 9 mutually stagger, and so that permeable hole 9 is more evenly distributed, into chamber
The underground water of room 7 is also more evenly；The discharge area of the permeable hole 9 of base pipe is greater than the discharge area of the permeable hole 9 of outer tube, can protect
The thick worry of card provides enough waters for essence worry, promotes filter efficiency；The not set permeable hole 9 of inner tube 6,7 upper and lower end of chamber opening,
It after underground water enters chamber 7, flows to 7 both ends of chamber, is discharged from 7 upper and lower end of chamber, design in this way extends ground
It is lauched the flow path in filter core, improves filter effect, since in filter process, filter core is easy to happen displacement, conglomeration, Gu
Determine part 61 and fixed function risen to stainless steel filter core, when filtering, the flowing of water will not be such that filter core is subjected to displacement, filter core will not conglomeration,
To ensure that the normal work of filter core, filter effect is improved；The environment of underground is generally all relatively more severe, and corrosivity is stronger,
In the surface of 1 surfaces externally and internally of base pipe, the surfaces externally and internally of inner tube 6, the surfaces externally and internally of outer tube 5 and permeable hole 9 these and underground water
Or the part that soil directly contacts applies one layer of corrosion-resistant coating, can reduce the corrosion of filter component, prolong the service life.
First level filtering device filter opening is larger, is not easy to plug, and can filter out bulky grain sand, and two-stage filter filter opening is small,
Be easy blocking, tiny silt can be filtered out, by the way of this classified filtering, can more thoroughly filter out sand and
Reduce the probability of plugged filter.
Outer tube 5 is passed down through 11 inner circle of excrescence on base pipe, and outer tube excrescence 51 is pressed on base pipe on excrescence 11,
5 bottom of outer tube is pressed under base pipe on excrescence 12, by this dismountable mode by two-stage filter and by-pass filtration
Device is combined together, and in combination with rubber mat is lined between position, is compacted rubber mat, sealing by the self weight of two-stage filter
Effect is good, and silt will not be flowed out from gap；Two-stage filter and first level filtering device detachably separate, and can pass through outer tube 5
Two-stage filter is integrally lifted cleaning, maintenance or replacement by the hanging ring 52 of top setting, again will after cleaning, maintenance or replacement
Two-stage filter is hung in heat source well, is used in combination with first level filtering device, to solve good worry sand effect
The contradiction between blocking is easy with filter opening.
Filter for heat source well of the invention draw water it is different with the method for operation in recharge, it is specific as follows:
When drawing water, first level filtering device and two-stage filter collective effect are needed, secondary protection device is hung in into heat source
In well, outer tube 5 is passed down through 11 inner circle of excrescence on base pipe, and outer tube excrescence 51 is pressed on base pipe on excrescence 11, with
First level filtering device fits together, and the underground water containing silt flows through nylon yarn packet net 3, permeable through the bar shaped on base pipe 1
Hole 9 enters in heat source well, completes the by-pass filtration of silt by the filtering of nylon yarn packet net 3 and bar shaped permeable hole 9 outside well；Through
Underground water after crossing thick worry enters chamber 7 through the round permeable hole on outer tube 5, and the essence through stainless steel filter core is considered, from chamber 7,
Lower open mouth discharge, completes the secondary filtration of silt, to obtain the underground water source for meeting production requirement.
Recharge is that the water source after utilization is gone back to underground through heat source well irrigation to need to reduce the resistance of recharge by second level
Filter device is integrally hung out outside well, and recharge water is flowed out through the bar shaped permeable hole 9 on base pipe 1, is then flowed through nylon yarn packet net 3
Underground is returned to, with flow direction when filtering that draws water on the contrary, play the role of cleaning to first level filtering device, prevents filter hole from blocking,
Meanwhile after two-stage filter is hung out, it can be cleaned, repaired or be maintained.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
