Detailed implementation mode

[0027] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0028] Example:

[0029] Refer to Figures 1-3, a control device for an electromagnetic heating boiler disclosed by the utility model, includes an installation box 1 and an opening door 2 hinged to one side thereof. The inner bottom wall of the installation box 1 is provided with a boiler main body 4. A residual heat utilization pipe 5 is wound around the circumferential side of the boiler main body 4. A second water pump 10 is fixedly connected to one side of the installation box 1. The second water pump 10 is connected to the residual heat utilization pipe 5. The other side of the second water pump 10 is fixedly connected to a water replenishing tank 11 through a water outlet pipe. An electric motor 13 is fixedly connected to the upper end of the water replenishing tank 11. And the output end of the electric motor 13 is fixedly connected to a stirring shaft 21. The stirring shaft 21 movably penetrates through the inner top wall of the water replenishing tank 11. A warm water replenishing pipe 14 is fixedly connected to one side of the water replenishing tank 11. The other side of the warm water replenishing pipe 14 is fixedly connected to a first water pump 9. The upper end of the first water pump 9 is fixedly connected to a water adding pipe 8. And the water adding pipe 8 is connected to the inner wall of the boiler main body 4. A liquid level gauge 18 and a first temperature sensor 17 are fixedly connected to the inner bottom wall of the boiler main body 4. A heating pipe 19 is installed on the inner bottom wall of the water replenishing tank 11. A heater 16 is fixedly connected to one side of the water replenishing tank 11. Three second temperature sensors 23 are arranged in the water replenishing tank 11. The first temperature sensor 17 and the liquid level gauge 18 are arranged in the boiler main body 4 and can test the water level and temperature in the boiler main body 4. When the water level is too low and the liquid level gauge 18 senses that the water level in the boiler main body 4 is insufficient, the liquid level gauge 18 sends a signal and the alarm 6 gives an alarm. The first water pump 9 starts and can input the water in the water replenishing tank 11 into the boiler main body 4. However, if the water level in the boiler main body 4 is too low and cold water is directly introduced, the alternating of cold and heat is likely to damage the equipment in the boiler main body 4. The residual heat utilization pipe 5 can utilize the heat energy generated during the operation of the boiler main body 4 to heat the cold water in the residual heat utilization pipe 5. The heated water in the residual heat utilization pipe 5 enters the water replenishing tank 11. The water replenishing tank 11 can supplement the water with temperature into the boiler main body 4. Start the electric motor 13. The electric motor 13 can drive the stirring shaft 21 to rotate, which can make the water temperature in the water replenishing tank 11 mix more evenly and the water temperature more accurate, can better control the temperature of the water entering the boiler main body 4, and can also better control the water level in the boiler main body 4.

[0030] On one side of the installation box 1, there is a main water tank 12. On one side of the main water tank 12, there is a third water pump 24. Both sides of the third water pump 24 are fixedly connected with water delivery pipes 28. The two water delivery pipes 28 are respectively connected to the replenishing water tank 11 and the main water tank 12. The water delivery pipes 28 and the third water pump 24 will introduce cold water into the replenishing water tank 11 to adjust the water temperature in the replenishing water tank 11. On one side of the main water tank 12, there is a surplus heat compensation water pipe 25 fixedly connected. The surplus heat compensation water pipe 25 is connected to the second water pump 10. The surplus heat compensation water pipe 25 and the second water pump 10 cooperate to transport cold water into the surplus heat utilization pipe 5 to cool or keep warm the surface of the boiler main body 4. On one side of the main water tank 12, there is a cold water replenishing pipe 26 fixedly connected. The other side of the cold water replenishing pipe 26 is connected to the first water pump 9. The water adding pipe 8, the first water pump 9 and the main water tank 12 can transport cold water into the boiler main body 4. The main water tank 12 can supply water to the replenishing water tank 11, the surplus heat utilization pipe 5 and the boiler main body 4. Cold and hot water can be supplemented into the boiler main body 4 according to requirements, and water can also be supplemented into the surplus heat utilization pipe 5, so that the surplus heat utilization pipe 5 can utilize the surplus heat of the temperature of the surface of the boiler main body 4. The surplus heat utilization pipe 5 passes the water with temperature into the replenishing water tank 11 through the second water pump 10, and the heating pipe 19 can heat the water in the replenishing water tank 11 to prevent the water temperature from not meeting the requirements.

[0031] A first valve 15 is installed in the warm water replenishing pipe 14, and a second valve 27 is installed in the cold water replenishing pipe 26. The surplus heat compensation water pipe 25 and the second valve 27 can control the water volume and the water flow. When the first temperature sensor 17 and the liquid level gauge 18 sense that there is no water in the boiler main body 4 and the temperature in the boiler main body 4 is not high, cold water can be directly introduced into the boiler main body 4 through the main water tank 12, the cold water replenishing pipe 26, the first water pump 9 and the water adding pipe 8, so that the boiler main body 4 can heat the cold water.

[0032] On one side wall of the replenishing water tank 11, there is a protective groove 22. Three second temperature sensors 23 are fixedly connected to one side wall of the protective groove 22. There is a protective net 20 above the heating pipe 19. The protective net 20 is fixedly connected to the side wall of the replenishing water tank 11. The protective groove 22 and the second temperature sensors 23 can prevent the stirring shaft 21 from damaging the second temperature sensors 23.

[0033] On one side of the opened door 2, there is a display screen 3 installed. On the upper end of the installation box 1, there is an alarm 6 fixedly connected. On the inner top wall of the boiler main body 4, there is a pressure gauge 7 fixedly connected, and the pressure gauge 7 penetrates through the upper end of the installation box 1. The display screen 3 can display the data measured by the liquid level gauge 18, the first temperature sensor 17 and the second temperature sensors 23.

[0034] The implementation principle of the above embodiments is as follows: The first temperature sensor 17 and the liquid level gauge 18 are arranged in the boiler main body 4, and can measure the water level and temperature in the boiler main body 4. When the water level is too low and the liquid level gauge 18 senses that the water level in the boiler main body 4 is insufficient, the liquid level gauge 18 sends a signal and the alarm 6 gives an alarm. The external control system controls the first water pump 9 to start, and the water in the water replenishing tank 11 can be input into the boiler main body 4. However, if the water level in the boiler main body 4 is too low, if cold water is directly introduced, the alternation of cold and heat is likely to damage the equipment in the boiler main body 4. The waste heat utilization pipe 5 can utilize the heat energy generated during the operation of the boiler main body 4 to heat the cold water in the waste heat utilization pipe 5. The heated water in the waste heat utilization pipe 5 enters the water replenishing tank 11, and the water replenishing tank 11 can supply the water with temperature to the boiler main body 4. Starting the motor 13, the motor 13 can drive the stirring shaft 21 to rotate, which can make the water temperature in the water replenishing tank 11 mix more evenly and the water temperature more accurate, better controlling the temperature of the water entering the boiler main body 4 and also better controlling the water level in the boiler main body 4.
