[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a mine wellhead heat medium source heating device, including a heat exchange box 1, a vertical box 2 fixedly installed above the heat exchange box 1, and a wellhead heating cylinder 3 fixedly installed above the vertical box 2. The wellhead heating cylinder 3 is connected to a pipeline supplying air to the mine wellhead during use. A heat pipe 7 is installed inside the wellhead heating cylinder 3, with its lower end extending into the interior of the heat exchange box 1. A heat exchange medium, specifically a Freon-based organic working fluid, is installed inside the heat pipe 7. During heat exchange, the hot water in the heat exchange box 1 exchanges heat with the medium in the heat pipe 7. The medium absorbs heat and changes from a liquid state to a gaseous state, rising to the top of the heat pipe 7 in the wellhead heating cylinder 3. The high-temperature gaseous medium... Heat exchange occurs between the heat pipe 7 and the air inside the wellhead heating cylinder 3. The hot air inside the wellhead heating cylinder 3 is then transported to the wellhead. A hot water tank 4 is fixedly installed on one side of the heat exchange box 1. The hot water tank 4 has a water chamber 401 and an equipment chamber 402 inside. A return pipe 6 is fixedly installed on the lower side of the other side of the heat exchange box 1. The end of the return pipe 6 away from the heat exchange box 1 is fixedly connected to the hot water tank 4 and communicates with the water chamber 401. A water supply pipe 9 is installed on the upper side of one side inside the water chamber 401. One end of the water supply pipe 9 extends into the equipment chamber 402. A filter box 10 is fixedly installed below the water supply pipe 9. A bottom frame 15 is fixedly installed inside the filter box 10. A filter screen 16 is fixedly installed on the upper side of the bottom frame 15.

[0024] By setting up a filter box 10 and installing a filter screen 16 in the filter box 10, scale, impurities and particulate matter in the water can be effectively intercepted, preventing them from entering the heat exchange structure. This avoids problems such as pipe blockage, reduced heat exchange efficiency and equipment corrosion. The filtered clean hot water can ensure efficient heat transfer between the heat pipe and the heat exchange medium, which is conducive to stable heating at the mine wellhead and increases practicality.

[0025] Furthermore, the filter screen 16 is configured as a conical filter screen, and a shelf 17 is fixedly installed at the top inside the filter box 10, and a drop pipe 18 is fixedly installed in the middle below the shelf 17.

[0026] The conical filter screen makes it easier for impurities to accumulate at the bottom of the screen under gravity, making it easier to clean and discharge. The arrangement of the shelf 17 and the drop pipe 18 further optimizes the water flow path, ensuring that the water can fall to the middle of the filter screen 16, thus improving the stability of filtration efficiency.

[0027] Furthermore, a water suction pipe 12 is fixedly installed on one side of the filter box 10, a water pump 13 is fixedly installed on one side of the water suction pipe 12, a water supply pipe 5 is fixedly installed above the water pump 13, and the end of the water supply pipe 5 away from the water pump 13 extends to the top of the hot water tank 4 and is fixedly connected to the heat exchange box 1.

[0028] The suction action of the water pump 13 ensures that the filtered water in the filter box 10 can be stably and efficiently delivered to the heat exchange box 1, guaranteeing the continuous operation of the heat medium source heating device. At the same time, this design also facilitates the control and adjustment of the water flow to adapt to the needs of different working conditions, improving the flexibility and adaptability of the device.

[0029] Furthermore, an electric heating tube 8 is installed inside the water cavity 401, and the electric heating tube 8 is fixedly connected to the hot water tank 4. Two partitions 14 are installed inside the water cavity 401, and the partitions 14 are fixedly connected to the hot water tank 4. The two partitions 14 are arranged vertically in an alternating manner.

[0030] The electric heating tube 8 can directly heat the water in the water chamber 401, improving heating efficiency. The vertically crisscrossing baffles 14 increase the water flow path and residence time, allowing the water to more fully absorb the heat generated by the electric heating tube 8, further improving the heating effect and ensuring the uniformity and stability of heating.

[0031] Furthermore, a cover 11 is fixedly installed on the front end face of the filter box 10.

[0032] The cover 11 facilitates cleaning and maintenance of the inside of the filter box 10. When the filter screen 16 is clogged or needs to be replaced, the cover 11 can be opened directly for operation without disassembling the entire filter box 10, which improves maintenance efficiency and convenience.

[0033] Working principle: During use, the water in the water chamber 401 of the hot water tank 4 is heated by the electric heating tube 8, and the water pump 13 is started. The hot water flows into the filter box 10 through the water supply pipe 9. In the filter box 10, the conical filter screen 16 effectively intercepts scale, impurities and particulate matter in the water. The shelf 17 and the drop pipe 18 ensure that the water falls to the middle position of the filter screen 16, improving the stability of filtration efficiency. The filtered clean hot water is stably and efficiently transported to the heat exchange box 1 through the water supply pipe 5 under the action of the water suction pipe 12 and the water pump 13. In the heat exchange box 1, the hot water exchanges heat with the heat exchange medium in the heat pipe 7. The medium absorbs heat and changes from liquid to gas, rising to the top of the heat pipe 7 in the wellhead heating cylinder 3. The high-temperature gaseous medium exchanges heat with the air in the wellhead heating cylinder 3 through the pipe wall of the heat pipe 7. The hot air is then transported to the mine wellhead to achieve heating. At the same time, the water after heat exchange flows back to the water chamber 401 of the hot water tank 4 through the return pipe 6 to form a circulation, which increases practicality.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
