Description
Technical Field
[0001] This invention belongs to the technical field of geothermal water delivery equipment, specifically a geothermal water filtration and delivery device. Background Technology
[0002] Geothermal water typically refers to hot water resources originating from the Earth's interior, usually possessing high temperatures. These water sources can be used for heating, cooling, hot springs, greenhouse cultivation, industrial heating, and a variety of other applications. Geothermal water temperatures are generally relatively stable, unaffected by weather conditions, seasons, or temperature fluctuations. The temperature changes slowly deep underground, making geothermal water suitable for providing stable heat or cooling effects. However, existing geothermal water filtration and transportation devices mostly use pipelines. Because geothermal water contains many impurities, these impurities easily accumulate in the pipelines, requiring regular disassembly and flushing, which reduces pipeline sealing. Furthermore, filtration equipment cannot filter and remove impurities according to the water quality characteristics, resulting in slow flow rates during geothermal transportation and increasing the likelihood of filter blockage. Therefore, it is necessary to provide a geothermal water filtration and transportation device to address the problems mentioned in the background art. Summary of the Invention

[0037] Please see Figure 1 In this embodiment of the invention, a geothermal water filtration and delivery device includes:
[0038] Water supply pipe 1, one end of which is connected to a geothermal pump for constant pressure delivery of geothermal water, and the outer sleeve of the water supply pipe 1 is covered with a vacuum insulation pipe;
[0039] The adapter 11 is sealed and connected to one end of the water supply pipe 1, and the adapter 11 is provided with a water inlet port 12;
[0040] The water quality analyzer 13 is horizontally inserted into the adapter 11, and the water quality analyzer 13 can monitor the geothermal water quality in real time.
[0041] The pressure regulating filter mechanism 2 consists of multiple units arranged in series, each of which is connected in series to the water supply pipe 1. These multiple pressure regulating filter mechanisms can adaptively adjust according to the geothermal water quality detected by the water quality tester, ensuring filtration effect on the one hand and improving geothermal water transmission efficiency on the other, thus avoiding serious heat loss.
[0042] In this embodiment, the pressure regulating filter mechanism 2 includes:
[0043] A sealing cylinder 21 is inclinedly connected to a water supply pipe 1. A water inlet port is provided at the lower end of the sealing cylinder 21. A flow guide ring 22 is provided inside the water supply pipe 1 at the water inlet port of the sealing cylinder 21. The inner wall of the flow guide ring 22 has an arc-shaped structure.
[0044] The self-cleaning water filter assembly 3 is coaxially arranged inside the sealing cylinder 21. A drain port is provided on one side of the sealing cylinder 21. The geothermal water filtered by the self-cleaning water filter assembly 3 enters the water supply pipe through the drain port.
[0045] A sewage discharge channel 24 is located on one side of the upper end face of the sealing cylinder 21, with one end of the sewage discharge channel 24 extending into the self-cleaning water filter assembly 3; and
[0046] Pipe 23 is connected to the sewage channel 24. In other words, the geothermal water in the water supply pipe can enter the self-cleaning water filter assembly through the water inlet port, be filtered and transported by the self-cleaning water filter assembly, and then be discharged back into the water supply pipe.
[0047] In a preferred embodiment, the self-cleaning water filtration assembly 3 includes:
[0048] The upper fixing seat 31 is coaxially fixed inside the upper part of the sealing cylinder 21, and the lower connecting seat 32 is also provided inside the sealing cylinder 21 below the upper fixing seat 31;
[0049] The water filter screen 4 is installed between the upper fixed seat 31 and the lower connecting seat 32;
[0050] An adjusting seat 33 is rotatably disposed below the lower connecting seat 32. The adjusting seat 33 has multiple drain holes 34, and the lower connecting seat 32 has through holes 35. The drain holes 34 can communicate with the through holes 35 one by one.
[0051] A central rod 36 is vertically rotatably mounted inside the sealing cylinder 21, and one end of the central rod 36 passes through the lower connecting seat 32 and is fixed to the adjusting seat 33;
[0052] A rotary motor 37 is installed in the upper water-proof cavity of the sealing cylinder 21. One end of the central rod 36 is fixed to the output end of the rotary motor 37. The rotary motor can drive the adjusting seat to deflect in both forward and reverse operation. In other words, geothermal water enters the filter screen through the drain hole and through hole. After being filtered by the filter screen, impurity particles can be retained on the inner wall of the filter screen, thereby realizing the geothermal water filtration and transportation.
[0053] In this embodiment, the lower connecting seat 32 is also provided with a plurality of oblique holes 38. The oblique holes 38 can be connected to each drain hole 34 in the direction of the adjusting seat 33. One end of each oblique hole 38 is connected to the sealing cylinder 21 and located outside the filter screen 4.
[0054] The deflection angle range of the adjustment seat 33 is less than 40°, wherein the oblique holes and through holes are distributed alternately.
[0055] In this embodiment, a control valve is also provided on the water supply pipe 1 at the rear side of the self-cleaning water filter assembly 3. The control valve can close and control the flow during the cleaning of the filter screen 4 in the self-cleaning water filter assembly 3. A solenoid valve is connected to the drain pipe 23. That is, during the cleaning of the filter screen in the self-cleaning water filter assembly, the adjusting seat rotates to make the inclined hole connect with the drain hole. At this time, the geothermal water in the water supply pipe can flow into the outside of the filter screen through the inclined hole and form a reverse flushing of the filter screen. The control valve controls the water supply pipe to close, and the solenoid valve controls the drain pipe to open, so that impurities and sewage can be discharged through the sewage discharge channel to achieve the self-cleaning effect.
[0056] In this embodiment, an outer cavity cylinder 5 is fixed parallel to one side of the sealing cylinder 21. Guide disks 51 are fixed at both the top and bottom of the outer cavity cylinder 5. The filter screen 4 passes through the side wall of the outer cavity cylinder 5 and the sealing cylinder 21 and is wrapped around the guide disks 51. A transmission roller group 52 is rotatably arranged between the guide disks 51. The transmission roller group 52 can perform the turning transmission of the filter screen 4.
[0057] The filter screen 4 is made of a highly elastic and deformable alloy material, and micropores, small holes and medium holes are correspondingly opened on the filter screen 4. Multiple waterproof strips 53 are also embedded and fixed in the side walls of the outer cavity cylinder 5 and the sealing cylinder 21, so as to realize that each self-cleaning filter component performs micro-filtration, light filtration or medium filtration. Multiple self-cleaning filter components, under the cooperation of different filtration combinations, ensure the geothermal water transmission efficiency while improving the geothermal water filtration effect.
[0058] In a preferred embodiment, a plurality of isolation plates 6 are circumferentially distributed inside the sealing cylinder 21, and a shaft tube 62 is rotatably sleeved on the outside of the central rod 36. All the isolation plates 6 are fixed to the shaft tube 62. A reduction gear seat 63 is provided in the upper water-proof cavity of the sealing cylinder 21, and one end of the shaft tube 62 is inserted and fixed in the output shaft of the reduction gear seat 63.
[0059] Each of the isolation plates 6 is fixed with a stainless steel brush plate 61. In particular, multiple isolation plates 6 can divide the sealed cylinder into multiple isolation chambers, and the water filter can be used for micro-pore-small-pore combined filtration (or micro-pore-medium-pore, small-pore-medium-pore) in the transmission adjustment. The proportion of micro-pore-small-pore area can be controlled by the transmission roller group in the transmission adjustment. Small impurities are retained in the isolation chambers corresponding to the small-pore surface of the water filter, while micro-impurities are retained in the isolation chambers corresponding to the micro-pore surface of the water filter. This avoids impurities from mixing into the flow and affecting the filtration effect, thereby ensuring water quality filtration while further improving the geothermal water transmission efficiency and reducing heat loss.
[0060] In this embodiment, the filter screen 4 in each of the self-cleaning water filtration components 3 can be independently adjusted by the transmission roller group according to the geothermal water quality. The filter screen 4 is also provided with an unobstructed flow surface, that is, it has zero filtration effect on geothermal water quality (no flow rate obstruction).
[0061] Specifically, geothermal water enters the water supply pipe through the inlet port on the adapter. The geothermal water quality is monitored in real time by a water quality tester. When the geothermal water quality is poor, multiple pressure-regulating filtration mechanisms can simultaneously perform microporous filtration to improve filtration capacity. When the geothermal water quality is good, the filter screens in the multiple pressure-regulating filtration mechanisms can be combined and adjusted to ensure filtration effect while improving transmission efficiency, thereby reducing heat loss. Especially during cleaning and maintenance, the individual cleaning filter components are flushed by reverse conveying of geothermal water to the filter screen, combined with a stainless steel brush plate for scrubbing, resulting in a significant cleaning effect without manual intervention.
[0062] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
