Abstract
The utility model relates to a dual-layer wire wound filter used for water supply tubular wells, belongs to the technical field of filters for wells, and comprises a filter tube, internal backing ribs, external backing ribs, an inner filter wire and an outer filter wire. Filter holes are uniformly arranged on the wall of the filter tube at intervals, the internal backing ribs are uniformly arranged on the outer wall of the filter tube at intervals circumferentially, grooves are arranged on the internal backing ribs at intervals, the inner filter wire is wound on the internal backing ribs through the grooves, the external backing ribs are uniformly arranged on the periphery of the inner filter wire at intervals, and the outer filter wire is wound on the external backing ribs through the grooves arranged on the external backing ribs. Strength and filter quality of the filter are increased by aid of the dual-layer filter wire structure of the filter, thereby resolving the problem that service life of tubular wells is shortened because water pumps are abraded and motors are burnt out after sand enters the existing wire wound filter due to materials and structures thereof. The filter is simple in structure, reasonable in design and particularly suitable for tubular wells.
Description
Technical field:
The utility model relates to a kind of bilayer that is used for water supply well and twines a strainer, belongs to the pipe well filtration art.
Background technology:
Water supply well is called for short pipe well, and pipe well is to be vertically mounted on underground water intaking or to protect phreatic tubulose structure, is a kind of plumbing facility of industrial and agricultural production, city, traffic, national defense construction.Pipe well can be divided into water supply well, catch pit, recharge well by purposes; Be divided into pressure well (artesian well) and no pressure well (phreatic well) by phreatic type.Strainer is one of main member of water supply well, and strainer is divided into circular hole strainer, net covering filtrator, fills out the whetstone strainer, pastes the whetstone strainer, twines a strainer etc., and present domestic pipe well is most widely used for twining a strainer.Twining a strainer is to make skeleton by the tubing perforation, twines wire outward and is made, and its hole shape has circular hole, bar hole etc.An existing strainer that twines is because material and structural reason, in use is subjected to phreatic the influence very easily to be corroded and to stop up, particularly in position that water level often changes, be easy to occur big hole, and then produce drift sand wearing and tearing water pump, and burn motor, reduced the application life of pipe well.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, reasonable in design, use the metal filter wire twine silk complete after, can adopt polyester/epoxy powder coating on the filter wire surface, to increase corrosion resistance, also can directly adopt the plastics filter wire; Existing twine a filter because material and structure to solve, after in use being corroded and stopping up, very easily hole occurs and produce drift sand wearing and tearing water pump, reduce the Dual-layer wire wound filter that is used for water supply well of pipe well problem in service life.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of Dual-layer wire wound filter for water supply well, it is made of screen pipe, interior pad muscle, outer pad muscle, interior filter wire and outer filter wire, it is characterized in that: evenly be manufactured with filtering holes on the screen pipe tube wall, the interval evenly is provided with interior pad muscle on the outer wall circumference of screen pipe, be arranged at intervals with groove on the interior pad muscle, be wound with interior filter wire in the groove of interior pad muscle; The interval evenly is provided with outer pad muscle on the interior filter wire outer circumference, is arranged at intervals with groove on the outer pad muscle, is wound with outer filter wire in the groove of outer pad muscle.
Be between described interior pad muscle and the outer pad muscle to laminate and be respectively dislocation shape layout between shape setting, interior filter wire and the outer filter wire.
The utility model beneficial effect compared with prior art is:
The Dual-layer wire wound filter that should be used for water supply well was simple in structure, reasonable in design, use the metal filter wire twine silk complete after, can adopt polyester/epoxy powder coating on the filter wire surface, to increase its corrosion resistance.Also can directly adopt plastics filter wire alternative metals filter wire, reduce the manufacturing cost of filter.This filter has improved the intensity of filter, and then has improved the service life of pipe well owing to adopt double-deck filter wire structure.
Description of drawings:
Fig. 1 twines a structure of filter schematic diagram for a kind of bilayer that is used for water supply well;
Fig. 2 twines the sectional structure schematic diagram of a strainer for a kind of bilayer that is used for water supply well;
Fig. 3 twines the plan structure schematic diagram of a strainer for a kind of bilayer that is used for water supply well.
Among the figure: 1, screen pipe, 2, interior pad muscle, 3, outer pad muscle, 4, interior filter wire, 5, outer filter wire, 6, filtering holes, 7, groove.
The specific embodiment:
The Dual-layer wire wound filter that should be used for water supply well is made of screen pipe 1, interior pad muscle 2, outer pad muscle 3, interior filter wire 4 and outer filter wire 5, evenly be manufactured with filtering holes 6 on the tube wall of screen pipe 1, screen pipe 1 can be made of steel pipe, cast iron pipe, plastic tube, asbestos-cement pipe or pipe of concrete.The interval evenly is provided with interior pad muscle 2 on the outer wall circumference of screen pipe 1, is arranged at intervals with groove 7 on the interior pad muscle 2, and interior filter wire 4 is wrapped in the groove 7 of interior pad muscle 2.The interval evenly is provided with outer pad muscle 3 on interior filter wire 4 outer circumference, is arranged at intervals with groove 7 on the outer pad muscle 3, and outer filter wire 5 is wrapped in the groove 7 of outer pad muscle 3.Interior filter wire 4 and outer filter wire 5 are made of wire or plastic wire.
Described interior pad muscle 2 and outer pad muscle 3 are rectangle or circular bar, because interior filter wire 4 and outer filter wire 5 are wrapped on interior pad muscle 2 and the outer pad muscle 3 by groove 7, have strengthened the steadiness (referring to accompanying drawing 1～3) of interior filter wire 4 and outer filter wire 5.
The utility model use the filter wire of metal material twine silk complete after, can adopt polyester/epoxy powder coating on the filter wire surface, to increase its corrosion resistance, also can directly adopt the filter wire of plastic material, manufacturing cost is reduced.
Be between interior pad muscle 2 of the present utility model and the outer pad muscle 3 to laminate and be respectively dislocation shape setting between shape setting, interior filter wire 4 and the outer filter wire 5, the gap between the filter wire is determined by the size of sharpening sand grain in the water-bearing layer.This filter is improved the intensity of filter and filter quality by the structure setting of double-deck filter wire.During work, the gap between the logical filter wire makes the water infiltration, thereby stops silt to enter tubing string from filter bores 6, prevents the sand erosion water pump, burns motor, has improved the life-span that pipe well uses.
