Technical Field

[0001] This utility model relates to the field of mine waste heat recovery technology, specifically a green and low-carbon heat pump device that uses waste heat and renewable energy. Background Technology

[0002] Currently, to address the energy consumption for heating in mines, heat pumps are installed near the mines and connected to heat exchangers within the mines to recover waste heat. However, the connection between the heat pumps and heat exchangers is usually via valves and pipes, with traditional connections using flanges. Traditional valves and flanges lack insulation properties, causing some heat loss as the heat transfer medium flows through them, thus reducing the waste heat recovery rate in the mines. To address this, technological innovation is needed based on existing heat pump systems. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-4A green, low-carbon heat pump device utilizing waste heat and renewable energy includes a heat pump 1. The heat pump 1's distribution box is electrically connected to a wind turbine generator set built near a mine, thus achieving operation driven by green energy. An insulation assembly is installed on the outside of both the inlet and outlet pipes of the heat pump 1. The insulation assembly includes two semi-insulated boxes 2, which are symmetrically mirrored front and back. Concave frames 23 are fixedly installed on the outer walls of the semi-insulated boxes 2. The outer sides of the two concave frames 23... Positioning posts 24 are evenly fixed on the side walls. The concave frames 23 on the outer sides of the two sets of semi-insulated boxes 2 fit together, and an elastic ring 22 is fitted on the outer side of each pair of fitting concave frames 23. Positioning holes are evenly opened through the outer side walls of the elastic rings 22, and the positioning posts 24 are inserted into the positioning holes. The semi-insulated boxes 2, concave frames 23, and pins 21 are made of ceramic fiber material through integral molding. Ceramic fiber material has the characteristics of good heat preservation performance, strong insulation, non-conductive, and not prone to generating electricity. To prevent electromagnetic interference, and because the magnetic block 25 is small in size and far from the electrically controlled valve 14, the electrically controlled valve 14 located within the insulation component can operate normally. Pins 21 are evenly fixedly arranged on the rear side of the front concave frame 23, and magnetic blocks 25 are fixedly arranged on the rear side of the pins 21. Insertion holes are evenly arranged on the front side of the rear concave frame 23, and iron blocks 26 are fixedly arranged in the insertion holes. The pins 21 are inserted into the insertion holes, and the magnetic blocks 25 and iron blocks 26 attract each other, thus inserting the pins 21 into the insertion holes. The pin 21 is stabilized in the socket by the mutual magnetic attraction between the magnetic block 25 and the iron block 26, and the two sets of half-body insulation boxes 2 are then connected and combined into a complete insulation box. The elastic ring 22 is then fitted onto the concave frame 23 on the outside of the two sets of half-body insulation boxes 2, and the positioning pin 24 is inserted into the positioning hole of the elastic ring 22. The positioning pin 24 stabilizes the elastic ring 22 on the outside of the concave frame 23, and the rebound force of the elastic ring 22 makes the insulation box after the two sets of connections more stable.

[0020] An electrically controlled valve 14 is installed on the left side of heat pump 1, and a plate heat exchanger 11 is installed on the left side of the electrically controlled valve 14. A heat storage tank 12 is installed on the right side of heat pump 1. The liquid inlet pipe of heat pump 1 and the liquid outlet pipe of electrically controlled valve 14 are both connected by a set of first flanges 17. The two sets of first flanges 17 are fixedly connected by nuts and bolts. The liquid inlet pipe of electrically controlled valve 14 and the liquid outlet pipe of plate heat exchanger 11 are both connected by a set of second flanges 18. The two sets of second flanges 18 are fixedly connected by nuts and bolts. The liquid outlet pipe of heat pump 1 and the heat storage tank 12 are connected by a set of second flanges 18. The inlet pipes of heat pump 1 and controller 13 are all connected to a set of third flanges 19. The two sets of third flanges 19 are fixedly connected by nuts and bolts. The inlet pipes of heat pump 1, heat pump 1, plate heat exchanger 11, and controller 13 are all wrapped with insulation sleeves 16. A temperature sensor 15 is fixedly installed inside the outlet pipe of plate heat exchanger 11. The electric control valve 14, the first flange 17, and the second flange 18 are located inside the two sets of half-body insulation boxes 2 in the insulation assembly on the left side of heat pump 1. The third flange 19 is located inside the heat pump. Inside the two sets of half-body insulation boxes 2 in the right-side insulation assembly, a controller 13 is fixedly installed on the top of the heat pump 1. The controller 13 can be an industrial-grade programmable logic controller. Through a preset control algorithm, combined with the temperature monitoring of the temperature sensor 15, the electric control valve 14 performs the control work. The electric control valve 14 can be a DN200 electric regulating valve, and the temperature sensor 15 can be a K-type thermocouple. By connecting the plate heat exchanger 11 to the cooling system in the large underground equipment, the cooling circulating water in the large underground equipment is introduced into the plate heat exchanger 11 and heat is recovered by the heat transfer medium in the plate heat exchanger 11. Then the cooled circulating water returns to the equipment for further cooling. When the temperature sensor 15 detects that the heat transfer medium in the plate heat exchanger 11 reaches 20℃-50℃, the electric control valve 14 opens, so that the heat transfer medium in the plate heat exchanger 11 enters the heat pump 1 for heat exchange. Then the controller 13 stores the waste heat absorbed by the heat pump 1. The controller 13 is electrically connected to the electric control valve 14 and the temperature sensor 15.

[0021] Working principle: By electrically connecting the distribution box of heat pump 1 to the wind turbine generator set built near the mine, the operation is driven by green energy. By connecting plate heat exchanger 11 to the cooling system of the large underground equipment, the cooling circulating water of the large underground equipment is introduced into plate heat exchanger 11 and heat is recovered by the heat transfer medium in plate heat exchanger 11. The cooled circulating water is then returned to the equipment for further cooling. When the temperature sensor 15 detects that the heat transfer medium in plate heat exchanger 11 reaches 20℃-50℃, the electrically controlled valve 14 opens, allowing the heat transfer medium in plate heat exchanger 11 to enter heat pump 1 for heat exchange. The waste heat absorbed by heat pump 1 is then stored by controller 13.

[0022] Insert the pin 21 into the socket, and stabilize the pin 21 in the socket by the mutual magnetic attraction between the magnet 25 and the iron block 26. Then, connect the two sets of half-body insulation boxes 2 to form a complete insulation box. Then, put the elastic ring 22 on the concave frame 23 on the outside of the two sets of half-body insulation boxes 2, and insert the positioning post 24 into the positioning hole of the elastic ring 22. In this way, the positioning post 24 stabilizes the elastic ring 22 on the outside of the concave frame 23, and the rebound force of the elastic ring 22 makes the insulation box after the two sets of connection more stable. Through the cooperation of the insulation component and the insulation sleeve 16, the heat loss caused by the heat transfer medium flowing between the plate heat exchanger 11, the heat pump 1 and the heat storage tank 12 can be reduced, thereby ensuring the waste heat recovery rate of the mine.

[0023] The semi-insulated box 2, concave frame 23, and pin 21 are made of ceramic fiber material through integral molding. Ceramic fiber material has the characteristics of good heat preservation performance and strong insulation. It is non-conductive and does not easily generate electromagnetic interference. In addition, the magnetic block 25 is small in size and far away from the electric control valve 14, so as to ensure that the electric control valve 14 located in the heat preservation component can operate normally. After pulling the elastic ring 22 outward to separate it from the concave frame 23 and the semi-insulated box 2, the two sets of semi-insulated boxes 2 can be separated and disassembled, which facilitates the maintenance of the components located inside the heat preservation component.
