Surface is coated with corrosion-resistant coating；135 top of outer tube is provided with outwardly projecting annular outer tube excrescence 1351, and base pipe 131 is set
It is equipped on inwardly projecting ring foundation pipe that excrescence 1312, outer tube 135 are passed down through basis under excrescence 1311 and base pipe
1311 inner circle of excrescence on pipe, outer tube excrescence 1351 are pressed on base pipe on excrescence 1311, and 135 bottom of outer tube is pressed in basis
It manages on lower excrescence 1312, is lined with rubber mat on base pipe between excrescence 1311 and outer tube excrescence 1351, is protruded under base pipe
Body 1312 and outer tube are lined with rubber mat between 135 bottom.
Wherein first level filtering device carries out coarse filtration to silt, is mainly used for filtering out the sand of bulky grain；Base pipe 131 is managed
Bar shaped permeable hole 139 is evenly arranged on wall, upper and lower adjacent two rows mutually stagger, and permeable hole 139 is made to be more evenly distributed, and filter
Into base pipe 131 underground water also more evenly, nylon yarn packet net 133 is wrapped in outside pipe by protection 132 pad of block reinforcement, is used
Galvanized wire 134 is fixed, and underground water will enter in geothermal well, first has to the permeable hole by nylon yarn packet net 133 and base pipe
139 two layers of filtering, filter out the sand of bulky grain.Two-stage filter carries out refined filtration to silt, is mainly used for filtering out tiny
Silt, two-stage filter includes inner tube 136, outer tube 135, partition 138 and filter core, inner tube 136 and the coaxial cloth of outer tube 135
It sets, partition 138 is the connecting framework of inner tube 136 Yu outer tube 135, while the space between inner tube 136 and outer tube 135 being divided into more
The equal chamber 137 of a cross-sectional area, segmentation filtering in this way, each 137 water of chamber is uniform, can promote the effect of filtering
And efficiency, chamber 137 is interior to fill stainless steel filter core, and design in this way makes one entirety of entire two-stage filter, ties
Structure is secured；Meanwhile stainless steel filter core has good strainability, filtered underground water is able to satisfy system requirement,
Corrosion resistance, heat resistance, resistance to pressure, wearability are good, are able to satisfy severe underground environment, and core stomata uniformly, accurately filters smart
Degree, the flow of unit area is big, can improve the efficiency of refined filtration, meets system water demand, can reuse, exempt from after cleaning
Replacement, economizes on resources, reduces cost；Two-stage filter is mainly by the permeable hole 139 and chamber being located on 135 tube wall of outer tube
Two layers of filter core filtering in 137, upper and lower adjacent two column of permeable hole 139 mutually stagger, so that permeable hole 139 is more evenly distributed, enter
The underground water of chamber 137 is also more evenly；The discharge area of the permeable hole 139 of base pipe is greater than the water excessively of the permeable hole 139 of outer tube
Area can guarantee that coarse filtration provides enough waters for refined filtration, promote filter efficiency；The not set permeable hole 139 of inner tube 136, chamber
137 upper and lower ends opening after underground water enters chamber 137, is flowed to 137 both ends of chamber, is discharged from 137 upper and lower end of chamber, leads to
Such design is crossed, flow path of the underground water in filter core is extended, improves filter effect, due to filtering in filter process
Core is easy to happen displacement, conglomeration, and fixing piece 1361 plays fixed function to stainless steel filter core, and when filtering, the flowing of water will not make to filter
Core is subjected to displacement, filter core will not conglomeration to ensure that the normal work of filter core improve filter effect；The environment one of underground
As it is all relatively severe, corrosivity is stronger, in the interior appearance of 131 surfaces externally and internally of base pipe, the surfaces externally and internally of inner tube 136, outer tube 135
These with the part that underground water or soil directly contact apply one layer of corrosion-resistant coating for face and the surface of permeable hole 139, can reduce filtering
The corrosion of device component, prolongs 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 135 is passed down through 1311 inner circle of excrescence on base pipe, and outer tube excrescence 1351 is pressed on base pipe prominent
On body 1311,135 bottom of outer tube is pressed under base pipe on excrescence 1312, is filled secondary filtration by this dismountable mode
It sets and is combined together with first level filtering device, in combination with rubber mat is lined between position, pass through the self weight of two-stage filter
It is compacted rubber mat, sealing effect is good, and silt will not be flowed out from gap；Two-stage filter and first level filtering device detachably separate,
Two-stage filter can integrally be lifted to cleaning, maintenance or replacement by the hanging ring 1352 that 135 top of outer tube is arranged, clearly
Two-stage filter is hung in geothermal well again after washing, repair or replacing, is used in combination with first level filtering device, thus
Improve the quality at water source in geothermal well.
