[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example: Refer to Figures 1-6 A dust removal geothermal heating system with an automatic filter cleaning function, comprising:

[0040] The box 1 has a purification chamber and a filter chamber inside. The purification chamber is connected to an air inlet and an air outlet, and the filter chamber is connected to a water inlet and a water outlet.

[0041] The purification component is installed inside the purification chamber. When air flows through the purification chamber from the air inlet to the air outlet, the purification component is used to purify the air.

[0042] The filter assembly includes a filter cylinder 2 disposed in a filter chamber, a cleaning cylinder 3 coaxially disposed inside the filter cylinder 2, a gap being provided between the cleaning cylinder 3 and the filter cylinder 2, and a first filter element 4 for filtering impurities being disposed on the surface of the cleaning cylinder 3.

[0043] The cleaning mechanism includes a first ring 5 disposed in the gap, the first ring 5 slidingly contacting the first filter element 4, and a driving component disposed inside the cleaning cylinder 3, the driving end of the driving component being connected to the first ring 5, the first ring 5 reciprocating relative to the cleaning cylinder 3 via the driving component.

[0044] This invention separates the purification chamber and the filtration chamber in the housing 1, and installs a purification component in the purification chamber. As external air enters through the air inlet and exits through the air outlet of the purification chamber, the purification component purifies the air, ensuring clean indoor air and enhancing the functionality of the geothermal heating equipment. In addition, the filter cylinder 2 and the cleaning cylinder 3 in the filtration chamber can filter water. The first filter element 4, which is circumferentially arranged on the surface of the cleaning cylinder 3, cleans impurities in the water. As the geothermal heating equipment is used, impurities gradually accumulate on the first filter element 4. The first ring 5 is driven by the driving component to slide and contact the first filter element 4 in the gap, repeatedly scraping off the accumulated impurities on the first filter element 4, ensuring efficient cleaning of the first filter element 4. No manual intervention is required during the cleaning process, which effectively improves the cleaning efficiency.

[0045] Furthermore, the cleanup agencies also include:

[0046] The first partition 6 is fixed inside the box 1 and forms a sewage discharge chamber inside the box 1. An opening is provided on the first partition 6, and a connecting pipe 7 is provided in the opening. The connecting pipe 7 has the same inner diameter as the filter cylinder 2 and is connected to it. A first valve 8 is provided on the connecting pipe 7.

[0047] A drain component is installed inside the drain chamber. The drain end of the drain component slides in conjunction with the inner wall of the drain chamber. A drain port is provided on one side of the drain chamber. The drain component is used to discharge impurities along the drain port. A drain pipe 9 is connected inside the drain port.

[0048] This technical solution also includes a drain component inside the housing 1. The housing 1 is divided into a drain chamber by the first partition 6. It is understood that the drain chamber is connected to the filter chamber through the connecting pipe 7. The filter cylinder 2 is connected to the connecting pipe 7, and the inner diameter of the connecting pipe 7 is the same as the inner diameter of the filter cylinder 2. When the first ring 5 reciprocates to scrape off the impurities on the first filter element 4, it not only effectively avoids the first filter element 4 from becoming clogged and ensures the filtration efficiency, but also allows the impurities to directly enter the drain chamber through the gap and then be discharged through the drain component in the drain chamber, further improving the cleaning effect on impurities in the water.

[0049] Understandably, the connecting pipe 7 is equipped with a first valve 8. When cleaning impurities in the filter chamber, the first valve 8 is opened to connect the drain chamber and the filter chamber, thus avoiding the waste of resources caused by hot water being discharged from the drain chamber during normal indoor heating.

[0050] Furthermore, the sewage discharge components include:

[0051] The first motor 10 is fixed to the outer wall of the housing 1. The output shaft of the first motor 10 is fixed to a screw 11. One end of the screw 11 extends into the sewage discharge chamber and is rotatably connected to the housing 1.

[0052] The scraper 12 is installed in the sewage discharge chamber. One end of the scraper 12 is threadedly connected to the screw 11 through the slider 13. The scraper 12 is fixedly connected to the slider 13. The scraper 12 slides in contact with the inner wall of the sewage discharge chamber through the screw 11.

[0053] The first motor 10 rotates the screw 11, which drives the slider 13 and the scraper 12 to move along the inner wall of the sewage discharge chamber to clean the impurities scraped off by the first ring 5, thereby improving the cleaning efficiency. Furthermore, the first motor 10 and the screw 11 can be arranged in several pairs to ensure the effect of sliding contact between the scraper 12 and the inner wall of the sewage discharge chamber.

[0054] Furthermore, the outer periphery of the cleaning cylinder 3 is provided with several grooves, and several first filter elements 4 are provided. Each first filter element 4 is correspondingly placed in one of the grooves. A hollow groove is provided on one side of the cleaning cylinder 3. A fixing seat 14 is fixedly connected in the hollow groove. A through groove is provided on the fixing seat 14. Rubber plates 15 are fixedly connected to opposite sides of the inner wall of the through groove. The close ends of the rubber plates 15 are in contact.

[0055] Reference Figure 4 , Figure 5 By opening several grooves on the outer periphery of the cleaning cylinder 3, it can be understood that the first filter element 4 is covered with an insert (not shown in the figure). The insert has a hollow structure in the middle and can be disassembled by external force when embedded in the groove. While ensuring that the first filter element 4 can properly adsorb and filter impurities, it is also convenient to replace and disassemble after long-term filtration. The corresponding outer wall of the box 1 is provided with an openable sealing door 30, which is the prior art and will not be described in detail. It is convenient to replace and maintain the filter components. Several through holes are opened on the filter cylinder 2 to facilitate the adsorption of impurities by the first filter element 4. The first filter element 4 can be made of common porous fiber sponge or activated carbon and other materials.

[0056] It should be noted that the heating water is common tap water, and its internal impurities are mostly scale. Therefore, the first filter element 4 in this technical solution mainly functions to adsorb rather than to isolate and filter a large amount of dirt. Therefore, the first ring 5 can scrape the first filter element 4 to prevent the pores on the surface of the first filter element 4 from being blocked, ensuring long-term adsorption of impurities. However, when the surface of the first filter element 4 accumulates too much impurities due to long-term use, the first ring 5 can scrape off enough accumulated impurities on the first filter element 4 for sewage discharge. It is not that the first ring 5 can scrape off the impurities on the surface of the first filter element 4 simply by starting it.

[0057] As stated above, the primary function of the first filter element 4 in this technical solution is adsorption, while referring to... Figure 3 It is known that there is a space between the filter cylinder 2 and the heating element 23. It can be understood that by fixing a baffle plate (not shown in the figure) in the filter chamber, the filter cylinder 2 and the heating element 23 are separated. A connecting hole is opened on the baffle plate, and a pipe is fixed in the connecting hole. A filter screen and an on / off valve are installed in the pipe. The filtered water after adsorption filtration is passed into the receiving cavity formed by the baffle plate and the box 1 to provide a storage function for heating water and meet the needs of timely use of heating for personnel. Alternatively, the filtered water can be passed into an external water storage tank (not shown in the figure) through the outlet pipe 28. The function of storing filtered water is a common existing technology, so it will not be described in detail.

[0058] Furthermore, this technical solution has a slot on the cleaning cylinder 3, a fixed seat 14 is fixedly connected in the slot, and a rubber plate 15 is fixedly connected in the through groove opened in the fixed seat 14. The rubber plates 15 are arranged opposite each other and abut against each other on the side close to each other, which can ensure the sealing of the cleaning cylinder 3 during the sliding of the first ring 5.

[0059] Furthermore, the driving components include:

[0060] The second motor 16 is fixedly connected to the housing 1. One end of the reciprocating screw 19 is fixedly connected to the output shaft of the second motor 16. The other end of the reciprocating screw 19 extends into the cleaning cylinder 3 and is rotatably connected to the bracket 31 in the connecting pipe 7. The bracket 31 is fixedly connected to the connecting pipe 7.

[0061] The second ring 17 is set inside the cleaning cylinder 3. The inner ring of the second ring 17 is threaded on the reciprocating screw 19, and the outer ring of the second ring 17 slides in contact with the inner wall of the cleaning cylinder 3.

[0062] The connecting plate 18 is slidably connected in the through groove. The connecting plate 18 abuts against the rubber plate 15. The two ends of the connecting plate 18 are respectively fixed to the first ring 5 and the second ring 17.

[0063] The cleaning cylinder 3 is equipped with a second ring 17. The second ring 17 is threaded onto the reciprocating screw 19, and the connecting plate 18 and the through groove limit the second ring 17 to prevent it from rotating. This allows the second ring 17 to reciprocate along the reciprocating screw, driving the first ring 5 to reciprocate as well. This scrapes the inner wall of the filter cylinder 2 and the outer wall of the cleaning cylinder 3, and cleans the first filter element 4. Furthermore, the rubber plate 15 ensures a sealed environment inside the cleaning cylinder 3. As the second ring 17 reciprocates, the cleaning cylinder 3 automatically forms a pumping action, which agitates the water in the filter chamber, accelerates the circulation of impurities in the water through the first filter element 4, and improves the adsorption efficiency of impurities. In addition, the reciprocating motion of the second ring 17 effectively reduces the possibility of the first filter element 4 becoming clogged.

[0064] Furthermore, the inner diameter of the cleaning cylinder 3 is smaller than the diameter of the second ring 17, and the inner diameter of the filter cylinder 2 is smaller than the diameter of the first ring 5.

[0065] Understandably, the outer wall of the first ring 5 is covered with a flexible layer for cleaning the first filter element 4. The outer side wall of the second ring 17 is covered with a flexible layer, while its inner ring is made of a rigid material to ensure the strength of the transmission with the reciprocating screw thread. The flexible layer is made of common materials such as brushes and rubber. By ensuring that the flexible layer is in contact with the contact surface, the inner diameter of the second ring 17 is larger than that of the cleaning cylinder 3 and the inner diameter of the first ring 5 is larger than that of the filter cylinder 2, the scraping effect is achieved.

[0066] Furthermore, the purification components include:

[0067] The fan 20 is fixedly fitted with a second partition 21 inside the housing 1. The second partition 21 separates the purification chamber and the filtration chamber inside the housing 1. The fan 20 is fixedly connected to the top surface of the second partition 21, and the air outlet of the fan 20 is connected to the air outlet.

[0068] The second filter element 22 is installed inside the purification chamber, and the air inlet of the fan 20 is connected to the air inlet through the second filter element 22.

[0069] The purification chamber is separated by the second partition 21. The fan 20 and the second filter element 22 are placed in the purification chamber so that the outside air enters from the air inlet, passes through the second filter element 22 and the fan 20 in sequence, and then enters the room from the air outlet. The air inlet can selectively communicate with the outside air and / or the indoor air.

[0070] Furthermore, a heating element 23 is fixedly connected to one side of the filter cylinder 2 inside the filter chamber, and the heating element 23 is connected to an external power source.

[0071] The water in the filter chamber is heated by the heating element 23, causing impurities in the water to precipitate out. The filter assembly then filters and adsorbs these impurities.

[0072] Furthermore, an air inlet pipe 24 is connected to the air inlet, and an air outlet pipe 25 is connected to the air outlet. Safety valves 26 are installed in the air inlet pipe 24 and the air outlet pipe 25.

[0073] Furthermore, an inlet pipe 27 is connected to the inlet, and an outlet pipe 28 is connected to the outlet. A second valve 29 is provided on the inlet pipe 27 and the outlet pipe 28 respectively.

[0074] The working process of this embodiment is as follows:

[0075] Water is introduced into the filter chamber by first opening the second valve 29 of the inlet pipe 27 and heating it through the heating element 23. During the heating process, the second motor 16 is started to rotate the reciprocating screw 19, which drives the second collar 17 to reciprocate along the inner wall of the cleaning cylinder 3. The rubber plate 15 ensures the sealing effect inside the cleaning cylinder 3. The second collar 17 generates a pumping effect in the cleaning cylinder 3, which accelerates the water through the first filter element 4 and improves the filtration efficiency. The second collar 17 can also drive the first collar 5 to reciprocate through the connecting plate 18, which scrapes off the impurities accumulated on the first filter element 4 to prevent the first filter element 4 from becoming blocked, so that the first filter element 4 can adsorb more impurities and enhance the filtration effect. Then, the second valve 29 is opened to introduce the heated hot water into the room through the outlet pipe 28 for underfloor heating. When it is necessary to clean impurities, the first valve 8 is opened to allow the scraped impurities to pass through the gap between the filter cylinder 2 and the cleaning cylinder 3 into the drain chamber. The first motor 10 is started to drive the screw 11 to rotate, thereby moving the scraper 12 to push the impurities to the drain outlet for discharge.
