Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment of a geothermal rapid sand removal and filtering device, including a filter tank 1. The filter tank 1 is the main body of the entire device and plays the role of containing and filtering geothermal fluid. A cover plate 2 is fixedly connected to the upper side of the filter tank 1. The cover plate 2 is fixed to the upper side of the filter tank 1 to close the filter tank 1 to prevent the geothermal fluid from splashing out during the filtering process. At the same time, it also provides support for other components installed on the cover plate 2. A filter screen 6 is fixedly connected to the inside of the filter tank 1. After the geothermal fluid enters the filter tank 1, the sand and other impurities therein are intercepted by the blocking effect of the filter screen 6, so that the filtered geothermal fluid is purer. A scraper is arranged inside the filter screen 6. The scraping component can continuously scrape the inner wall of the filter 6 to clean up the sand attached to the filter 6 to ensure the filtering efficiency of the filter 6. A baffle 8 is arranged inside the cover plate 2 to enclose the scraped sand. A cleaning component is arranged outside the baffle 8 to clean up the sand. A water pump 21 is installed at the bottom of the filter tank 1. Through the action of the water pump 21, the geothermal fluid can be filtered through the filter 6 at a certain pressure and flow rate to improve the filtering efficiency. The output end of the water pump 21 is fixedly connected with a three-way valve 22. The setting of the three-way valve 22 allows the filtered geothermal fluid to be transported in different directions as needed;

[0033] Reference Figure 2 The scraping assembly includes a motor 3, which is installed on the upper side of the cover plate 2. The motor 3 is used as the power source of the scraping assembly and is installed on the upper side of the cover plate 2 for easy maintenance and operation. The output end of the motor 3 is fixedly connected to a rotating shaft 4, which transmits the power of the motor 3 to other parts of the scraping assembly. The outer side of the rotating shaft 4 is fixedly connected to a spiral blade 5, which can scrape the inner wall of the filter 6 during rotation. The bottom of the rotating shaft 4 is fixedly connected to a shell 11, which provides an installation space for the striking assembly and the cleaning assembly. The striking assembly and the cleaning assembly are installed on the outer side of the shell 11. The striking assembly can continuously strike the filter 6 to shake off the stubborn impurities on the filter 6, thereby further improving the filtering effect. The cleaning assembly can rinse the filter 6, rinse the scraped impurities and residual geothermal fluid, and maintain the cleanliness of the filter 6.

[0034] Reference Figure 3-Figure 5 The cleaning assembly includes a plurality of scrapers 7, which are all mounted on the upper outer side of the rotating shaft 4. The scrapers 7 rotate driven by the rotating shaft 4 to scrape and clean the outer side of the baffle 8 and the top of the filter tank 1.

[0035] Reference Figure 3-Figure 5The striking assembly includes four mounting plates 14, which provide mounting positions for other components of the striking assembly. The adjacent sides of the four mounting plates 14 are fixedly connected to the outer side of the shell 11, and a sliding rod 18 is fixedly connected inside the mounting plate 14. The sliding rod 18 provides a track for the sliding of the slider 17. The slider 17 is slidably connected to the outer side of the sliding rod 18. When the slider 17 is subjected to external force, it can slide quickly on the sliding rod 18, driving the striking plate 15 to strike the filter 6. The striking plate 15 is fixedly connected to the upper side of the slider 17, and the striking plate 15 directly contacts the filter 6 to strike the filter 6. The bottom of the adjacent sides of the four striking plates 15 is fixedly connected to a push plate 16. The push plate 16 pushes the slider 17 to slide during the operation of the striking assembly. A spring 19 is sleeved on the outer side of the sliding rod 18. When the slider 17 performs a striking action under the push of the push plate 16, the spring 19 can pull the slider 17 back to the initial position to prepare for the next striking.

[0036] Reference Figure 2 and Figure 3 The cleaning component includes four water spray pipes 12, and the adjacent ends of the four water spray pipes 12 are fixedly connected to the inside of the shell 11. The water spray pipes 12 provide a water spray channel for the cleaning component. A plurality of nozzles 13 are fixedly connected to the outside of the water spray pipes 12. The nozzles 13 can spray the water in the water spray pipes 12 onto the filter 6 at a certain pressure and angle to clean the filter 6.

[0037] Reference Figure 1 and Figure 2 A delivery pipe 9 is fixedly connected to the outside of the filter tank 1, and the delivery pipe 9 is used to transport the impurities filtered out of the filter tank 1 to a collection box 10. A collection box 10 is fixedly connected to the bottom of the delivery pipe 9, and the collection box 10 is used to collect the impurities filtered out of the filter tank 1.

[0038] Reference Figure 2 The bottom of the scraper 7 fits with the top of the filter tank 1, ensuring that the cleaning component can effectively clean the top of the filter tank 1. The outer side of the spiral blade 5 fits with the inner wall of the filter screen 6, so that the scraping component can scrape the filter screen 6 more thoroughly.

[0039] Reference Figure 3-Figure 5 A plurality of inclined plates 20 are fixedly connected to the bottom of the filter screen 6. The inclined plates 20 are used to drive the striking assembly to operate. The inclined plates 20 are fitted with the push plates 16 to improve the striking effect of the striking assembly. One end of the spring 19 is fixedly connected to the inner wall of the mounting plate 14, and the other end of the spring 19 is fixedly connected to the side of the slider 17 away from the push plate 16, so that the spring 19 can play a role of resetting and buffering during the movement of the slider 17.

[0040] Reference Figure 1-Figure 3A converter tube 23 is fixedly connected to the outside of the three-way valve 22, and one end of the converter tube 23 away from the three-way valve 22 is fixedly connected to the inside of the shell 11. The converter tube 23 is used to connect the three-way valve 22 and the inside of the shell 11. One end of the converter tube 23 is fixedly connected to the inside of the shell 11, so that the cleaning component can obtain a stable water supply.

[0041] Working principle: When the geothermal water needs to be filtered, the geothermal water is extracted into the filter tank 1. At this time, the geothermal water will enter the filter 6 for filtration. Then, the motor 3 is energized to generate rotation. The rotation of the motor 3 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the spiral blade 5 to rotate. The rotation of the spiral blade 5 scrapes off the impurities filtered inside the filter 6 and transports them to the inside of the cover plate 2.

[0042] The rotation of the rotating shaft 4 will also drive the scraper 7 to rotate. The scraper 7 rotates to clean the impurities conveyed by the spiral blades 5 and convey them to the collection box 10 through the conveying pipe 9 for collection.

[0043] The rotating shaft 4 will also drive the housing 11 to rotate while rotating. The rotation of the housing 11 will drive the mounting plate 14 to rotate. The rotation of the mounting plate 14 will drive the striking plate 15 to rotate, and further drive the push plate 16 to rotate. When the push plate 16 rotates and fits between the inclined plate 20, the inclined plate 20 will make the push plate 16 slide through its own shape, and further drive the slider 17 to slide to squeeze the spring 19. At this time, the housing 11 continues to rotate, so that the push plate 16 continues to move. When the push plate 16 rotates and fits between the inclined plate 20, the inclined plate 20 will make the push plate 16 slide through its own shape, and further drive the slider 17 to slide to squeeze the spring 19. At this time, the housing 11 continues to rotate, so that the push plate 16 continues to move. When filter 16 is not in contact with inclined plate 20, sliding rod 18 will be reset, thereby pushing sliding block 17 to slide, further driving push plate 16 to slide, so that push plate 16 hits filter screen 6, and starts three-way valve 22 again, so that water pump 21 extracts filtered water and transports it to the inside of shell 11 through exchange pipe 23, and rinses the outside of filter screen 6 through water spray pipe 12 and nozzle 13 to clean impurities attached to filter screen 6, and at the same time, the shell 11 is rotated to achieve better cleaning effect.
