Description

Technical Field

[0001] This utility model relates to the technical field of boiler fan speed regulation equipment, specifically to a waste heat steam boiler fan speed regulation and energy-saving device. Background Technology

[0002] Waste heat boilers refer to boilers that collect flue gas generated during operation, then use the flue gas to heat water, and finally utilize the steam generated. This is a common waste heat recovery and utilization method for boilers. The fan is one of the main components of the boiler, which can regulate the temperature of the boiler combustion chamber to ensure that the combustion chamber maintains a certain temperature, thereby enabling the boiler to operate smoothly.

[0003] Because the function of the fan is generally to run for a long time, this increases energy consumption. Moreover, once the boiler fan is turned on, it basically maintains a high power operation, which is also one of the main reasons for energy consumption. Therefore, a regulating device is needed to reduce the energy consumption of the fan. So, a waste heat steam boiler fan speed regulation and energy saving device is proposed here. Utility Model Content

[0004] The technical problem this invention aims to solve is that boiler fans generally maintain a high power output once started, which is one of the main causes of energy consumption. This invention provides a waste heat steam boiler fan speed regulation and energy-saving device to adjust the power of the fan and reduce energy consumption.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a waste heat steam boiler fan speed regulation and energy-saving device, wherein a fan is detachably connected to one end side wall of the boiler, a flue gas pipe is fixedly connected to the side wall of the boiler near the fan, and an electric wire is fixedly connected to the side wall of the fan away from the boiler and near the bottom. The end of the electric wire away from the fan is inserted and connected to an adjusting plate. An inner groove is opened in the adjusting plate, and a partition plate is fixedly connected to the side wall in the middle of the inner groove. Mounting boxes are evenly embedded in the partition plate. A resistor is detachably connected in each mounting box, and contact electrode plates are fixedly connected to both ends of the resistor.

[0006] Each of these resistors has a different specification.

[0007] As a preferred embodiment of this utility model, a sliding groove is provided through one side wall of the adjustment plate, and a passive electrode plate is embedded in the side wall of the adjustment plate opposite to the sliding groove. The adjustment plate is divided into two sliding cavities by a partition plate, and an input column and a transition column are slidably connected in each cavity. A U-shaped toggle block is fixedly connected to the top side wall of the input column and the transition column. One end of the wire passes through the side wall of the adjustment plate and is fixedly connected to one end of the side wall of the passive electrode plate.

[0008] As a preferred embodiment of this utility model, both the input column and the adapter column are hollow structures. A positioning plate is fixedly connected to the inner wall of the input column, a spring is fixedly connected to one side wall of the positioning plate, an input electrode plate is fixedly connected to one end of the spring, and a power supply line is inserted and connected inside the input column.

[0009] As a preferred technical solution of this utility model, one end of the power supply line passes through the positioning plate and spring and is fixedly connected to one side wall of the input electrode plate. The power supply line is slidably connected in the sliding groove. A power-conducting post is embedded in the adapter post. The two ends of the power-conducting post are respectively attached to the passive electrode plate and the contact electrode plate. The input electrode plate is attached to the contact electrode plate on the other side of the resistor.

[0010] As a preferred technical solution of this utility model, the top openings of the two cavities of the inner groove are movably connected to top plates. The top plates are telescopic stacked structures. Each cavity has a pair of top plates, and one end of each pair of top plates is fixedly connected to the two side walls of the input column and the adapter column, respectively. One side wall of the adjusting plate is fixedly connected to a fixed baffle. The fixed baffle is an L-shaped structure and a telescopic rod is embedded in the middle of its top. The output end of the telescopic rod is detachably connected to one side wall of the toggle block.

[0011] This invention has the following advantages: When needed, the telescopic rod can be activated to drive the actuating block, moving the input column and the adapter column. This allows the energized column and input electrode to contact the contact electrode plates on the two ends of different resistors. The current is adjusted by using resistors of different specifications. Furthermore, by utilizing the principle that different loads result in different currents and power outputs, the fan speed is changed, achieving the adjustment function. This avoids the fan operating at high power for extended periods, thus reducing energy consumption. Additionally, the telescopic rod can be connected to a thermostat to adjust the speed according to temperature changes.

[0012] The automatic adjustment function increases practicality. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Referring to Figures 1-3, this utility model discloses a waste heat steam boiler fan speed regulation and energy-saving device. A fan 3 is detachably connected to one side wall of the boiler 1. A flue gas pipe 2 is fixedly connected to the side wall of the boiler 1 near the fan 3. An electric wire 4 is fixedly connected to the side wall of the fan 3 away from the boiler 1 and near the bottom. An adjusting plate 5 is inserted through the end of the electric wire 4 away from the fan 3. An inner groove 8 is opened in the adjusting plate 5. A partition plate 9 is fixedly connected to the middle side wall of the inner groove 8. Mounting boxes 11 are evenly embedded in the partition plate 9. A resistor 12 is detachably connected in each mounting box 11. Contact electrode plates 13 are fixedly connected to both ends of the resistor 12. Each resistor 12 has a different specification.

[0019] A sliding groove 10 is formed through one side wall of the adjusting plate 5. A passive electrode plate 19 is embedded in the side wall of the adjusting plate 5 opposite to the sliding groove 10. The adjusting plate 5 is divided into two sliding cavities by a partition plate 9, and an input post 14 and a transition post 17 are slidably connected in each cavity. A U-shaped toggle block 6 is fixedly connected to the top side wall of the input post 14 and the transition post 17. One end of the wire 4 passes through the side wall of the adjusting plate 5 and is fixedly connected to one end of the side wall of the passive electrode plate 19. Both the input post 14 and the transition post 17 are hollow structures. A positioning plate 22 is fixedly connected to the inner wall of the input post 14. A spring 23 is fixedly connected to one side wall of the positioning plate 22. An input electrode plate 16 is fixedly connected to one end of the spring 23. A power supply line is inserted into the input post 14.

[0020] 15. One end of the power supply line 15 passes through the positioning plate 22 and the spring 23 and is fixedly connected to one side wall of the input electrode plate 16. The power supply line 15 is slidably connected in the sliding groove 10. A power-conducting post 18 is embedded in the adapter post 17. The two ends of the power-conducting post 18 are respectively attached to the passive electrode plate 19 and the contact electrode plate 13. The input electrode plate 16 is attached to the contact electrode plate 13 on the other side of the resistor 12.

[0021] The technical effect of this solution is as follows: pushing the toggle block 6 moves the input post 14 and the adapter post 17. As they move, the input electrode plate 16 and the energized post 18 can contact different contact electrode plates 13. By connecting to different resistors 12, different current phenomena can be achieved. By adjusting the current, the power of the fan 3 can be adjusted. Under the same load, different currents result in different speeds, thereby achieving the effect of adjusting the speed of the fan 3. This avoids the fan 3 from being at the same speed for a long time, which would increase energy consumption. By adjusting, energy consumption can be reduced, and adjustments can be made according to the situation of the boiler 1, thus improving practicality.

[0022] The top openings of the two cavities of the inner groove 8 are movably connected to the top plates 21. The top plates 21 are telescopic stacked structures. Each cavity has a pair of top plates 21, and one end of each pair of top plates 21 is fixedly connected to the two side walls of the input column 14 and the adapter column 17, respectively. One side wall of the adjusting plate 5 is fixedly connected to a fixed baffle 7. The fixed baffle 7 is an L-shaped structure and a telescopic rod 20 is embedded in the middle of the top. The output end of the telescopic rod 20 is detachably connected to one side wall of the toggle block 6.

[0023] The technical benefits of this solution are as follows: the top plate 21 connected to the adjusting plate 5 can seal the inner groove 8, ensuring the relative airtightness of the space inside the inner groove 8, thereby reducing the probability of safety accidents. At the same time, because the top plate 21 is a telescopic stacked structure, it does not affect the movement of the actuating block 6 while ensuring the airtight seal. Automated control can be achieved through the telescopic rod 20, avoiding safety problems caused by manual adjustment.

[0024] Specifically, in use, when needed, the telescopic rod 20 drives the actuating block 6 to move the input post 14 and the adapter post 17 within the corresponding cavity. As they move, the input electrode plate 16 and the energizing post 18 come into contact with the contact electrode plates 13 at both ends of resistors 12 of different specifications. Current is input through the power supply line 15, and the current is adjusted by the resistor 12. Finally, the adjusted current is transmitted to the passive electrode plate 19 through the energizing post 18.

[0025] The current is fed through the passive electrode plate 19 to the wire 4 and finally supplied to the fan 3. Because the resistor 12 will change the current, and the current can change the power of the fan 3, the speed of the fan 3 can be adjusted, thus avoiding the fan 3 from running at high power for a long time and causing energy consumption.

[0026] The telescopic rod 20 can be connected to the temperature control device of the boiler 1 to realize automatic control of the boiler 1 according to the temperature change. This allows for adjustments based on actual needs and increases practicality.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
