[0032] Example 1

[0033] Reference Figs. 1-3 A gas and sand removal equipment for geothermal water is applied to the gas and sand removal of geothermal water, in order to improve the filtering efficiency of geothermal water, and facilitate the removal and cleaning of the filtering assembly.

[0034] The gas and sand removal device for geothermal water comprises a filter cylinder 1, a lifting plate 3, a mounting cylinder 7 and a degassing cylinder 5.

[0035] The bottom of the filter cylinder 1 is provided with a water inlet pipe 101 and a blowdown pipe 102. The geothermal water extracted can be injected into the inside of the filter cylinder 1 through the water inlet pipe 101, so as to be filtered. The blowdown pipe 102 is provided with an electromagnetic valve, and the opening and closing of the blowdown pipe 102 can be controlled through the electromagnetic valve, so as to facilitate the discharge of the sand and stones deposited in the inside of the filter cylinder 1.

[0036] The lifting plate 3 is arranged above the filter cylinder 1. The bottom of the lifting plate 3 is provided with a lifting mechanism, which comprises a push rod 2. The push rod 2 is an electric push rod. The lower end of the push rod 2 is fixedly connected with the outer wall of the filter cylinder 1, and the upper end is connected with the bottom of the lifting plate 3. The lifting plate 3 can be lifted through the electric push rod 2. The mounting cylinder 7 is fixedly connected with the bottom of the lifting plate 3. The sidewall of the mounting cylinder 7 is provided with a filter layer 8. The lifting of the lifting plate 3 can drive the mounting cylinder 7 to move up and down, so as to facilitate the mounting cylinder 7 to move away from the filter cylinder 1 and clean the filter layer 8 on the mounting cylinder 7.

[0037] The mounting cylinder 7 is in a cylindrical shape. The sidewall of the mounting cylinder 7 is provided with a plurality of mounting openings at intervals in the circumferential direction. Each mounting opening is internally fixedly mounted with a filter layer 8. The sidewall of the cylindrical mounting cylinder 7 can be mounted with a plurality of filter layers 8, so as to expand the filtering area and improve the filtering efficiency. The filter layer 8 comprises an outer shell and a filter screen. The outer shell is in a square frame shape. The filter screen is fixedly connected with the inside of the outer shell. The geothermal water can be filtered through the filter screen to remove the impurities in the geothermal water.

[0038] The inside of the filter cylinder 1 is provided with a support ring 9. The top of the support ring 9 is fixedly connected with a positioning ring 901. The bottom of the mounting cylinder 7 is provided with an annular groove. The annular groove is adapted with the positioning ring 901. When the mounting cylinder 7 descends with the lifting plate 3, the mounting cylinder 7 can be placed on the support ring 9. At this time, the positioning ring 901 will be inserted into the annular groove. Since the top of the positioning ring 901 is provided with a sealing ring 902, when the positioning ring 901 is inserted into the annular groove, the sealing ring 902 will seal between the mounting cylinder 7 and the support ring 9, so as to avoid the leakage of the geothermal water without passing through the filter layer 8.

[0039] A connecting pipe 4 is connected between the degassing cylinder 5 and the filter cylinder 1, and the end of the connecting pipe 4 connected to the filter cylinder 1 is higher than the support ring 9. An electromagnetic valve is arranged on the connecting pipe 4. The geothermal water filtered by the filter layer 8 can enter the degassing cylinder 5 through the connecting pipe 4 to discharge the gas. The top of the degassing cylinder 5 is provided with an exhaust pipe 501, and the bottom is provided with a drain pipe 502. An electromagnetic valve is arranged on the drain pipe 502. The geothermal water after degassing can be discharged through the drain pipe 502. A gas pump (not shown in the figure) is arranged on the exhaust pipe 501. The gas in the degassing cylinder 5 can be extracted by the gas pump to help the gas in the geothermal water to be discharged, thereby improving the degassing effect.

[0040] Embodiment 2

[0041] In order to increase the degassing effect of the device, a rotating shaft is rotatably connected in the degassing cylinder 5. A stirring rod 601 is arranged on the outside of the rotating shaft. A driving motor 6 is arranged on the top of the degassing cylinder 5. The output shaft of the driving motor 6 is connected to the rotating shaft. The stirring rod 601 can be rotated by the driving motor 6 to stir the geothermal water in the degassing cylinder 5, thereby facilitating the discharge of the gas in the geothermal water.

[0042] The working principle of the degassing and sand removing equipment for geothermal water is as follows: The extracted geothermal water is injected into the inside of the filter cylinder 1 through the water inlet pipe 101. The geothermal water flows upward from the bottom of the filter cylinder 1, passes through the support ring 9, and comes to the middle part of the installation cylinder 7. In the process of the upward flow of the geothermal water, the heavier sand and stones are deposited downward to the bottom of the filter cylinder 1. The geothermal water coming to the middle part of the installation cylinder 7 is then filtered by each filter layer 8 to remove the impurities in the geothermal water. Then the filtered geothermal water comes to the outside of the installation cylinder 7.

[0043] The electromagnetic valve on the connecting pipe 4 is opened to make the filtered geothermal water come into the degassing cylinder 5. Then the electromagnetic valve on the connecting pipe 4 is closed to make the degassing cylinder 5 in a sealed state. Then the stirring rod 601 can be rotated by the driving motor 6 to stir the geothermal water in the degassing cylinder 5, thereby facilitating the discharge of the gas in the geothermal water. At this time, the gas in the degassing cylinder 5 is extracted by the gas pump to further help the discharge of the gas in the geothermal water, thereby improving the degassing effect. After the gas in the geothermal water is discharged, the electromagnetic valve on the drain pipe 502 is opened to discharge the geothermal water after degassing and sand removing.

[0044] When the filter layer 8 needs to be cleaned, the lifting plate 3 is driven by the electric push rod 2 to rise, thereby driving the installation cylinder 7 at the bottom of the lifting plate 3 to move upward, so that the installation cylinder 7 moves away from the filter cylinder 1. At this time, the filter layer 8 on the installation cylinder 7 can be conveniently cleaned or replaced.

[0045] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
