Description
Technical field
This utility model relates to a kind of old well and repairs well washing apparatus, belongs to technical field of building construction.
Background technology
In recent years, with due to factors impacts such as geologic structure, hydrogeologic condition and Features of Hydrochemistries, pipe well occurs in that during life-time service filter pipe silts up successively, and water yield reduces；Water strainer is broken, gushes hourglass gravel in well；Well casing tilts, the phenomenon such as subside in well week.Wherein filter pipe Severe blockage, water yield falls sharply becomes universal distinct issues, and specific capacity the most all decays to 30-40% during former one-tenth well, and indivedual pipe wells are only 5% during former one-tenth well, causes water head site water supply capacity to decline.Existing well washing apparatus uses liquid carbon dioxide closed well washing, air compressor machine well-flushing, and the pipe well well washing effect for well depth 150m-300m is the best, how to improve pipe well well washing effect, has become as the direction solving shortage of water resources.
Utility model content
The purpose of this utility model is the problems referred to above existed for existing technology, it is provided that a kind of pipe well going for various internal diameter size, the old well prosthetic device that the duration is short, efficiency is high.The technical scheme that this utility model provides is: well washing apparatus repaired by a kind of old well, including pump line, immersible pump, capsule, appendix, air compressor, described capsule is two grades of hollow cylinder structures, it is installed with uniform through hole on described capsule bottom, use between the base of described immersible pump and capsule and threaded, described pump line and immersible pump use the first Flange joint, use threaded between described capsule bottom and the second flange, it is installed with transfer port on described capsule, transfer port on the capsule in succession of described appendix one end, other end air compressor in succession.
Preferably, described capsule being installed with and is positioned at top the first cylinder, is positioned at bottom the second cylinder, described first column diameter is less than the second cylinder, and described transfer port is fixedly arranged on the first cylinder.
Preferably, described appendix at least can bear 0.6MPa pressure.
Preferably, described air compressor can reach 0.6MPa pressure.
Beneficial effect: the utility model discloses a kind of old well and repair well washing apparatus, before specific capacity can reach well-flushing after using this device to carry out well-flushing operation 5～10 times, using through repetition test shows compared with prior art, has simple installation, the duration is short, can effectively improve the advantages such as old well behaviour in service.
Accompanying drawing explanation
Fig. 1 is the structural representation of old well prosthetic device.
Fig. 2 is capsule structure schematic diagram.
As shown in the figure: 1, pump line, 2, immersible pump, 3, capsule, 4, air compressor, 5, appendix, the 6, first flange, the 7, second flange, the 301, first cylinder, 302, transfer port, the 303, second cylinder.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and referring to the drawings this utility model is further described.
Well washing apparatus repaired by old well as shown in drawings, including pump line 1, immersible pump 2, capsule 3, air compressor 4, appendix 5, described capsule 3 is two grades of hollow cylinder structures, it is installed with uniform through hole on described capsule 3 bottom, use between the base of described immersible pump 2 and capsule 3 and threaded, described pump line 1 uses the first flange 6 to be connected with immersible pump 2, threaded with using between the second flange 7 bottom described capsule 3, transfer port 302 it is installed with on described capsule, transfer port 302 on the capsule 3 in succession of described appendix 4 one end, other end air compressor 5 in succession.Being installed with on described capsule 3 and be positioned at top the first cylinder 301, be positioned at bottom the second cylinder 303, described first cylinder 301 diameter is less than the second cylinder 303, and described transfer port 302 is fixedly arranged on the first cylinder 301.Described appendix 5 at least can bear 0.6MPa pressure.Described air compressor 4 can reach 0.6MPa pressure.
First using air compressor 4 to input compressed air by appendix 5 to capsule when this utility model is operated, compressed air uniform through hole ejection from capsule the second cylindricality 303 carries out pre-cleaning to the borehole wall.While air compressor 4 works, immersible pump 1 draws water, the negative pressure formed during by drawing water, compressed air is constantly pressed into water-bearing layer from capsule the second cylinder 303, water-bearing layer is carried out repeated stock, and destroys tamper, make interpore various dirt thing thoroughly be removed；Draw water for a long time and accumulate in the fine sand granule of screen casing surrounding and also gone out in a large number, enable subsoil water quickly to pour in, to reach the purpose of blocking inside and outside dredging pipe well.When carrying out well-flushing work, by adjusting the position of pump line 2, the first flange 6 and the second flange 7 is made to form a well-flushing space closed, it is achieved the working effect of the segmentation cleaning borehole wall.
Being described this utility model and embodiment thereof above, this description does not has restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto.If generally speaking those of ordinary skill in the art is enlightened by it, in the case of creating objective without departing from this utility model, design the frame mode similar to this technical scheme and embodiment without creative, protection domain of the present utility model all should be belonged to.
