Description

A kind of anticlogging geothermal well screen casing
Technical field
The utility model relates to underground heat equipment technical field, especially a kind of anticlogging geothermal well screen casing.
Background technique
Geothermal energy is a kind of clean energy resource, is renewable energy, and development prospect is very wide, bushing pipe method be geothermal well at One kind of well method, needs to use filter pipe or bushing pipe is filtered landwaste and gravel, filter structure one in the prior art As be that main pipe is used to be filtered for round leakage hole and trapezoidal silk filter pipe into water, disclose a kind of title in the prior art For " a kind of screen casing for producing layer for geothermal well, the patent of notification number CN205955711U ", the master including being equipped with leakage hole Tube body and the strainer for being sheathed on main pipe periphery, are equipped with several support bars between the main pipe and strainer, the main pipe with The upper end of strainer is equipped with the connector for jointed rod, and the bottom of the main pipe is equipped with a pedestal, which uses double Layer filtering, filter effect is good, but there is also a geothermal well common problems, are used for a long time, and filter device is easy hair Raw blocking, causes water flow not smooth, however geothermal well screen construction in the prior art is not easy to dismantle repeatedly, and the cleaning frequency compares It grows, therefore will affect the normal operation use of geothermal well once screen casing blocking, influence the working efficiency of geothermal well, reduce ground The service life of hot well.
Summary of the invention
In order to overcome deficiency existing for existing geothermal well screen casing, the utility model provides a kind of anticlogging geothermal well use Screen casing improves filter effect, while anti-blocking supporting structure effectively prevent gravel and debris blockage mistake in prior art basis Filtering layer extends the service life of geothermal well, improves the working efficiency of geothermal well.
The utility model in order to solve the technical problem the technical scheme adopted is that a kind of anticlogging geothermal well screen casing, Including connector, filter layer, main pipe, anti-blocking supporting structure and pedestal;Main pipe is equipped with equally distributed permeable hole, filtering Layer is equipped with trapezoidal filter pipe;The top of main pipe is equipped with connector, and the bottom of main pipe is equipped with pedestal;It is set in filter layer inner wall There is a supporting block, anti-blocking supporting structure assigns into the space that supporting block, filter layer and main pipe are formed, and anti-blocking supporting structure can be from It is disassembled in the space that three is formed;Anti-blocking supporting structure includes rack body, partition and suspension plate;The shape of rack body Outer wall for arcuate shape identical with main pipe's radian, rack body is equipped with several partitions, and the top of rack body is equipped with Suspension plate, suspension plate are located at the top of main pipe.
Further, the material of anti-blocking supporting structure is all made of the stainless (steel) wire with filtering function.
The utility model has the beneficial effects that a kind of anticlogging geothermal well screen casing, is arranged in prior art basis Filter layer and anti-blocking supporting structure, improve filter effect, at the same dismountable anti-blocking supporting structure effectively prevent gravel and Debris blockage filter layer, easy access operating condition extend the service life of geothermal well, improve the working efficiency of geothermal well.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the front cross-sectional structural schematic diagram of the utility model.
Fig. 2 is the vertical view schematic cross-sectional view of the utility model.
Fig. 3 is the anti-blocking supporting structure cross-sectional view of the utility model.
1. connector in figure, 2. filter layers, 3. trapezoidal filter pipes, 4. main pipes, 5. rack bodies, 6. partitions, 7. is permeable Hole, 8. pedestals, 9. suspension plates, 10. supporting blocks.
Specific embodiment
Referring to attached drawing, a kind of anticlogging geothermal well screen casing, including connector 1, filter layer 2, main pipe 4, anti-blocking branch Frame structure and pedestal 8, main pipe 4 are equipped with equally distributed permeable hole 7, and filter layer 2 is equipped with trapezoidal filter pipe 3;Main pipe 4 Top be equipped with connector 1, connector 1 is used for jointed rod, and the bottom of main pipe 4 is equipped with pedestal 8;It is set in 2 inner wall of filter layer There is supporting block 10, is used to support filter layer 2;Anti-blocking supporting structure assigns into what supporting block 10, filter layer 2 and main pipe 4 were formed In space, anti-blocking supporting structure can be disassembled out of three is formed space;Anti-blocking supporting structure include rack body 5, every Plate 6 and suspension plate 9;The shape of rack body 5 is arcuate shape identical with 4 radian of main pipe, and the outer wall of rack body 5 is equipped with Several partitions 6, for carrying tamper;The top of rack body 5 is equipped with suspension plate 9, and suspension plate 9 is located at the top of main pipe 4 Portion, for fixing anti-blocking supporting structure;The material of anti-blocking supporting structure is all made of the stainless (steel) wire with filtering function, does not influence While crossing water function, moreover it is possible to which the effect for further functioning as filtering can be by anti-blocking branch when tamper excessively causes water flow unsmooth The disassembly of frame structure is taken out, and partition 6 and rack body 5 can take tamper out of simultaneously, and scale removal process is convenient and efficient.
