Description

Technical Field

[0001] This utility model relates to the field of tailwater utilization technology, and more specifically, to a geothermal well tailwater utilization heating equipment. Background Technology

[0002] Geothermal wells are special wells with a depth of approximately 3500 meters, generating electricity by extracting geothermal energy or hot spring water with a temperature exceeding 30°C. Based on the temperature of geothermal resources, they can be divided into three categories: high-temperature geothermal (>150°C), existing in the form of steam, which can directly drive turbines; medium-temperature geothermal (90-150°C), existing in a water-steam mixture, requiring heat exchangers or flash evaporation technology to generate electricity; and low-temperature geothermal (25-90°C), mostly liquid hot water, often relying on heat pumps to enhance the heat quality before generating electricity. This tiered utilization helps to efficiently develop geothermal energy and achieve a sustainable supply of clean energy. In existing heating equipment, multiple sets of bolts and nuts are commonly used to fix the filter plates within the installation cylinder to ensure stability. However, this traditional installation method has significant drawbacks: when the filter plates need maintenance, replacement, or cleaning, operators must unscrew and remove multiple sets of bolts and nuts one by one, a tedious and time-consuming process. Frequent disassembly not only affects work efficiency but may also lead to bolt thread wear or nut loss due to repeated disassembly and assembly, thus affecting sealing and stability. Therefore, it is urgent to optimize and improve the installation structure of the filter plate. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a geothermal well tailwater utilization heating equipment, which has the advantage of facilitating the installation of filter plates in the installation cylinder.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a geothermal well tailwater utilization heating device, including an installation cylinder, a fixing groove is provided inside the installation cylinder, a fixing strip is movably installed in the fixing groove, a filter plate is fixedly installed between two fixing strips, and a limit groove is provided on the outer side of the installation cylinder.

[0005] A spring is fixedly installed inside the mounting cylinder, a connecting block is fixedly installed on the front of the filter plate, a limit block is fixedly installed at one end of the connecting block, and the outer diameter of the limit block is smaller than the inner diameter of the limit block. A telescopic rod is fixedly installed inside the mounting cylinder.

A fan is provided inside the heat conducting cylinder.

[0007] As a preferred embodiment of this utility model, a support column is fixedly installed around the bottom of the mounting cylinder, and a base is fixedly installed at the bottom of the support column.

[0008] As a preferred embodiment of this utility model, both the mounting cylinder and the fixing plate have threaded holes inside, and the threaded holes are arranged in a linear array.

[0009] As a preferred embodiment of this utility model, the telescopic rod and the spring are arranged in pairs, with a total of four sets fixedly installed inside the mounting cylinder.

[0010] As a preferred embodiment of this utility model, a push rod is fixedly installed on the front side of the filter plate, and the inside of the push rod presents a U-shaped form.

[0011] As a preferred embodiment of this utility model, the outer diameter of the fixing strip is equal to the inner diameter of the fixing groove, and the interior of the fixing groove has a smooth surface design.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Compared with traditional heating equipment, this utility model, through the cooperation of telescopic rods, springs, limiting grooves, and limiting blocks, facilitates the installation of filter plates inside the installation cylinder, significantly optimizing the installation experience of filter plates inside the installation cylinder. The telescopic rods and springs provide elastic support for the filter plates, allowing them to be easily inserted and automatically positioned without the need for traditional bolts and nuts, simplifying the installation process. The precise cooperation between the limiting blocks and limiting grooves ensures the stability of the filter plates after installation, preventing them from moving or tilting during use. This design not only makes the installation and disassembly of filter plates faster and more convenient, but also improves the maintainability and operational efficiency of the equipment, while reducing component wear caused by frequent disassembly and extending the service life of the equipment.

[0014] 2. Compared with traditional heating equipment, this utility model cleverly incorporates a fan that rotates and connects to the upper part of the heat-conducting cylinder. This ensures the stability and sealing of the heat exchange process, and a fixed plate tightly seals the heat exchange box. When the heat from the wastewater needs to be utilized, the wastewater is slowly injected into the heat exchange box through a fixed pipe outside. As the wastewater is injected, the heat it carries is gradually transferred to the air inside the heat-conducting cylinder, causing the air temperature to rise continuously. At this time, the fan fixed inside the heat-conducting cylinder comes into play, and through the rapid rotation of the fan, the heated air inside the heat-conducting cylinder is powerfully blown out. This hot air, carrying the heat from the wastewater, is distributed into the room, effectively raising the indoor temperature and bringing warmth to the indoor environment. This ingenious design achieves full utilization of the heat from the wastewater, is both environmentally friendly and energy-saving, and provides an efficient way to regulate indoor temperature.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a geothermal well tailwater utilization heating device, including an installation cylinder 1. A fixing groove 18 is provided inside the installation cylinder 1, and fixing strips 17 are movably installed in the fixing groove 18. A filter plate 11 is fixedly installed between two fixing strips 17. Limiting grooves 16 are provided on the outer side of the installation cylinder 1.

[0024] A spring 20 is fixedly installed inside the mounting cylinder 1. A connecting block 15 is fixedly installed on the front of the filter plate 11. A limiting block 14 is fixedly installed at one end of the connecting block 15, and the outer diameter of the limiting block 14 is smaller than the inner diameter of the limiting block 14. A telescopic rod 19 is fixedly installed inside the mounting cylinder 1.

[0025] Before using the equipment, the operator needs to install the filter plate 11 inside the installation cylinder 1. First, install the filter plate 11 between the two fixing strips 17. Then, hold the push rod 12 and slowly push the fixing strips 17 into the fixing groove 18. The fixing groove 18 drives the filter plate 11 and the connecting block 15 to move synchronously. The filter plate 11 squeezes the telescopic rod 19 and the spring 20 inside the fixing groove 18, causing the connecting block 15 to move synchronously. The limiting block 14 quickly enters the limiting groove 16. The limiting groove 16 installs the limiting block 14, thus completing the installation of the filter plate 11 inside the installation cylinder 1.

[0026] Before using this equipment, the filter plate 11 needs to be installed inside the installation cylinder 1. Specifically, first place the filter plate 11 between the two fixing strips 17, then hold the push rod 12 and slowly push the fixing strips 17 into the fixing groove 18. During this process, the fixing groove 18 will cause the filter plate 11 and the connecting block 15 to move synchronously. As they move, the filter plate 11 presses against the telescopic rod 19 and the spring 20 within the fixing groove 18, causing the connecting block 15 to simultaneously push the limiting block 14 into the limiting groove 16. Finally, the limiting block 14 is installed using the limiting groove 16. Thus, the installation of the filter plate 11 inside the installation cylinder 1 is successfully completed. Compared with traditional heating equipment, this heating equipment, through the telescopic rod 19, spring 20, ... The fit between the limiting groove 16 and the limiting block 14 facilitates the installation of the filter plate 11 inside the mounting cylinder 1, significantly optimizing the installation experience of the filter plate 11 inside the mounting cylinder 1. The telescopic rod 19 and the spring 20 provide elastic support for the filter plate, allowing it to be easily inserted into the filter plate 11 and automatically positioned without the need for traditional bolts and nuts, simplifying the installation process. The precise fit between the limiting block 14 and the limiting groove 16 ensures the stability of the filter plate after installation, preventing it from moving or tilting during use. This design not only makes the installation and disassembly of the filter plate 11 faster and more convenient, but also improves the maintainability and operating efficiency of the equipment, while reducing component wear caused by frequent disassembly and extending the service life of the equipment.

[0027] The mounting cylinder 1 is fixedly mounted with a fixing plate 4 on top, and a heat exchange box 2 is fixedly mounted on top of the fixing plate 4. A circulation box 3 is fixedly mounted on the outer surface of the heat exchange box 2. A valve 5 is fixedly mounted between the heat exchange box 2 and the circulation box 3. There are two valves 5. A fixing pipe 13 is fixedly mounted on the outside of the valve 5. A heat conduction cylinder 6 is fixedly mounted inside the heat exchange box 2. A gas guide pipe 21 is fixedly mounted at the bottom of the heat conduction cylinder 6. One end of the gas guide pipe 21 passes through the inside of the fixing plate 4. A fan 10 is provided inside the heat conduction cylinder 6.

[0028] The staff fixedly connected the tailwater pipe to the fixed pipe 13, and then opened valve 5, allowing the tailwater to enter the heat exchange box 2 and the circulation box 3 through the fixed pipe 13. The heat of the tailwater heated the air inside the heat exchange box 2 and the circulation box 3. Now, inside the heat conduction cylinder 6, valve 5 slowly blows the air out, thus improving the indoor temperature. At the same time, a support column 7 is set below the heat conduction cylinder 6 to ensure smooth airflow inside the heat conduction cylinder 6. Valves 5 are installed between the heat exchange box 2 and the circulation box 3, and both valves 5 are connected to the heat exchange box 2 through pipes. During use, the temperature measuring component detects the water temperature and controls valve 5 to drain the water into the heat exchange box 2, and then re-enter the circulation box 3 through the other valve 5, so as to achieve full utilization of heat and complete the utilization of tailwater.

[0029] After securely connecting the tailwater pipe to the fixed pipe 13, open valve 5. The tailwater then flows through the fixed pipe 13 into the heat exchange box 2 and the circulation box 3. Inside the heat exchange box 2 and the circulation box 3, the heat from the tailwater heats the internal air. Simultaneously, a fan 10 is installed inside the heat conduction cylinder 6, slowly blowing out the hot air to raise the indoor temperature. To ensure smooth airflow inside the heat conduction cylinder 6, a support column 7 is specifically installed below it. Notably, valves 5 are installed between the heat exchange box 2 and the circulation box 3, and both valves 5 are connected to the heat exchange box 2 and the circulation box 3 via pipes. During operation, the temperature measuring component monitors the water temperature in real time and precisely controls valve 5, allowing the discharged water to flow back into the heat exchange box 2 and then re-enter the circulation through valve 5 on the other side. This fully utilizes the heat and efficiently utilizes the tailwater, achieving a significant improvement over traditional heating equipment. In this heating device, a fan 10 is cleverly connected to the upper part of the heat-conducting cylinder 6. To ensure the stability and sealing of the heat exchange process, a fixing plate 4 is used to tightly seal the heat exchange box 2. When the heat from the wastewater needs to be utilized, the wastewater is slowly injected into the heat exchange box 2 through a fixed pipe outside. As the wastewater is injected, the heat it carries is gradually transferred to the air inside the heat-conducting cylinder 6, causing the air temperature to rise continuously. At this time, the fan 10, fixedly installed inside the heat-conducting cylinder 6, comes into play. By rapidly rotating, the fan 10 powerfully blows out the heated air from the heat-conducting cylinder 6. This heated air, carrying the heat from the wastewater, is distributed into the room, effectively raising the indoor temperature and bringing warmth to the indoor environment. This ingenious design achieves full utilization of the wastewater heat, is both environmentally friendly and energy-saving, and provides an efficient way to regulate indoor temperature.

[0030] Among them, support columns 7 are fixedly installed around the bottom of the mounting cylinder 1, and a base 8 is fixedly installed at the bottom of the support columns 7.

[0031] Since the bottom of the mounting cylinder 1 is fixedly supported by support columns 7, and the bottom of the support columns 7 is fixedly supported by a base 8, the cooperation between the base 8 and the support columns 7 facilitates stable support for the mounting cylinder 1 and reduces the instability of the support columns 7 and the base 8 during use.

[0032] Both the mounting cylinder 1 and the fixing plate 4 have threaded holes 9 inside, and the threaded holes 9 are arranged in a linear array.

[0033] Since the threaded holes 9 are arranged in a linear array inside the mounting cylinder 1 and the fixing plate 4, it is convenient for the workers to slowly screw the bolts into the threaded holes 9. The mounting cylinder 1 and the fixing plate 4 are fixed by the bolts, which ensures the stability of the mounting cylinder 1 and the fixing plate 4 during use.

[0034] The telescopic rod 19 and the spring 20 are arranged in pairs, with a total of four sets fixedly installed inside the mounting cylinder 1.

[0035] Since the telescopic rod 19 and the spring 20 are installed in pairs, there are four sets of fixed installation inside the mounting cylinder 1. Through the cooperation between the telescopic rod 19 and the fixing groove 18, the mounting cylinder 1 can provide stable support for the filter plate 11, reduce the shaking of the filter plate 11 during use, and improve the efficiency of the filter plate 11.

[0036] Among them, a push rod 12 is fixedly installed on the front of the filter plate 11, and the inside of the push rod 12 has a U-shaped form.

[0037] Because the push rod 12 is U-shaped on the front of the filter plate 11, and the U-shaped push rod 12 is ergonomically designed, it reduces the stress on the workers during the installation of the filter plate 11.

[0038] The outer diameter of the fixing strip 17 is equal to the inner diameter of the fixing groove 18, and the interior of the fixing groove 18 has a smooth surface design.

[0039] Since the outer diameter of the fixing strip 17 is equal to the inner diameter of the fixing groove 18, and the interior of the fixing groove 18 has a smooth surface design, it is convenient to install the filter plate 11 inside the fixing groove 18 with the fixing strip 17, thus ensuring the installation efficiency of the filter plate 11.

[0040] Working principle and usage process of this utility model:

[0041] Before using the equipment, the operator needs to install the filter plate 11 inside the installation cylinder 1. First, install the filter plate 11 between the two fixing strips 17. Then, hold the push rod 12 and slowly push the fixing strips 17 into the fixing groove 18. The fixing groove 18 drives the filter plate 11 and the connecting block 15 to move synchronously. The filter plate 11 squeezes the telescopic rod 19 and the spring 20 inside the fixing groove 18, causing the connecting block 15 to move synchronously. The limiting block 14 quickly enters the limiting groove 16. The limiting groove 16 installs the limiting block 14, thus completing the installation of the filter plate 11 inside the installation cylinder 1.

[0042] The staff fixedly connected the tailwater pipe to the fixed pipe 13, and then opened valve 5, allowing the tailwater to enter the heat exchange box 2 and the circulation box 3 through the fixed pipe 13. The heat of the tailwater heated the air inside the heat exchange box 2 and the circulation box 3. Now, inside the heat conduction cylinder 6, valve 5 slowly blows the air out, thus improving the indoor temperature. At the same time, a support column 7 is set below the heat conduction cylinder 6 to ensure smooth airflow inside the heat conduction cylinder 6. Valves 5 are installed between the heat exchange box 2 and the circulation box 3, and both valves 5 are connected to the heat exchange box 2 through pipes. During use, the temperature measuring component detects the water temperature and controls valve 5 to drain the water into the heat exchange box 2, and then re-enter the circulation box 3 through the other valve 5, so as to achieve full utilization of heat and complete the utilization of tailwater.
