Description

Technical Field

[0001] The utility model relates to the technical field of circulating pumps, in particular to a circulating pump with a built-in heating function. Background Art

[0002] Circulating pumps are installed in heat stations (heat centers), heat sources or cold sources, etc. In the closed loop of a heating system or an air-conditioning water system, the circulating pump does not lift water to a high place, but makes the water circulate in the system repeatedly, overcoming the resistance loss of the loop, which has no direct relation with the height of the building. Therefore, it is called a circulating pump. The function of the circulating pump is to provide power for water circulation, continuously lift water to a high place, and ensure that the water can circulate in the system according to the set flow rate. Circulating pumps are mostly used in heating and air-conditioning water systems. For example, the circulating pump is installed on the return water pipe of the heating system.

[0003] The existing circulating pump can only play the role of pumping hot water and forced circulation. A large amount of heat is dissipated during the circulation of hot water, and the purpose of energy conservation and emission reduction cannot be achieved. For this reason, we have proposed a circulating pump with a built-in heating function. Content of the Utility Model

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] Refer to Figure 1-7 , a circulating water pump with a built-in heating function, including: a pump body 1 and a fixing ring 5. The inner side wall of the pump body 1 is provided with a mounting plate 2. A plurality of card slots 3 are evenly opened on the mounting plate 2. The inner side wall of the card slot 3 is fixedly clamped with a permanent magnet 4. A plurality of threaded rods 6 are threadedly connected to the fixing ring 5. The mounting plate 2 is fixedly connected to the inner side wall of the pump body 1 through the fixing ring 5 and the threaded rods 6. A through slot 7 is opened on the mounting plate 2. A pump shaft 8 is arranged in the through slot 7. One end of the pump shaft 8 is fixedly connected with a connecting rod 11 through a bolt. The end of the connecting rod 11 away from the pump shaft 8 is fixedly connected with a turntable 9. An impeller 10 is arranged on the turntable 9. The N-S poles of the adjacent permanent magnets 4 on the mounting plate 2 are arranged alternately in the reverse direction. The permanent magnet 4 is a permanent ferrite or a permanent magnetic alloy. The pump body 1 is provided with a water outlet 14 and a water inlet 13. An electric control valve 15 is arranged at the water outlet 14.

[0032] Specifically, when using the circulating water pump with the built-in heating function, the motor 21 is operated. The motor 21 drives the pump shaft 8 to rotate. The pump shaft 8 drives the turntable 9 to rotate through the connecting rod 11. The turntable 9 drives the impeller 10 to rotate. The impeller 10 rotates at a high speed under the drive of the motor 21 and cuts the magnetic field lines of the permanent magnet 4. The impeller 10 is in an alternating magnetic field. The alternating magnetic field generates an induced current in the impeller 10. The higher the frequency of the alternating magnetic field, the stronger the eddy current. The current thermal effect makes the impeller 10 become a heating body, heating the water while pumping the water. The heating effect is good and the temperature rises quickly. It can heat and supplement the heat energy of the hot water during the circulation process, which is more energy-saving and environmentally friendly.

[0033] The impeller 10 is arranged on the side of the turntable 9 away from the connecting rod 11. The material of the impeller 10 is pure copper. Since the resistivity of pure copper is extremely small, the eddy current is the strongest, and the current thermal effect is strong, generating a large amount of heat.

[0034] A thermometer 16 is fixedly connected to the pump body 1. One end of the thermometer 16 is provided with a probe 17, and the probe 17 is fixedly connected to the inner side wall of the pump body 1. A first fixing frame 19 is installed on the pump body 1. The first fixing frame 19 is fixedly connected to a base 12. A second fixing frame 20 is fixedly connected to the base 12. The second fixing frame 20 is fixedly connected to a motor 21. The other end of the pump shaft 8 is fixedly connected to the output end of the motor 21. A control panel 18 is arranged on the first fixing frame 19. The thermometer 16, the electric control valve 15 and the motor 21 are all electrically connected to the control panel 18.

[0035] Specifically, the operation of the motor 21 and the electric control valve 15 can be controlled through the control panel 18. The data fed back to the thermometer 16 through the probe 17 can be displayed on the control panel 18. By controlling the opening and closing of the electric control valve 15, the control panel 18 can respectively display the water temperature inside the pump body 1 and the overall ambient water temperature during circulation, which is convenient for detecting the heating situation and self-checking of the circulating water pump, and is more convenient to use with high practicability.
