Description

Technical Field

[0001] The utility model relates to the technical field of thermal energy utilization, in particular to an energy-saving device for efficient thermal energy utilization. Background Art

[0002] In view of the current concerns of the world's human beings about the crisis of living environment and the improvement of the concept of sustainable development, in order to seek alternative energy, as well as the energy and environmental crisis faced by my country and international pressure, the country has put forward the planning requirements of "energy conservation and emission reduction, low-carbon economy" in the "12th Five-Year Plan", and has also issued relevant laws and regulations and incentives for energy in recent years. However, our packaging company is a high-energy-consuming industry, which is closely related to "low-carbon economy, environmental protection economy and sustainable development". In the future production and life, it is imperative to develop low-carbon packaging, save energy, and recycle. It is a must for the survival, development and competition of packaging companies.

[0003] However, current thermal energy utilization devices are unable to fully utilize thermal energy and are unable to control the heat transfer efficiency, which limits the scope of application of the thermal energy utilization devices themselves. Utility Model Content

[0004] The purpose of the utility model is to provide an energy-saving device for efficient thermal energy utilization to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an energy-saving device for efficient thermal energy utilization, comprising a box body and a motor, one side of the box body is connected to a liquid inlet pipe through a pipeline, one side of the box body is connected to a liquid outlet pipe through a pipeline, one side of the box body is fixedly installed with an air inlet pipe, one end of the air inlet pipe is connected to a first support plate through a pipeline, one side of the first support plate is installed with a plurality of heat exchange fins, one side of the heat exchange fins is installed with a second support plate, and one side of the second support plate is installed with an air outlet pipe.

[0006] Preferably, a motor is fixedly mounted on one side of the box body, and one end of the motor is connected to a threaded rod via an output shaft.

[0007] Preferably, one end of the threaded rod is connected to a screw rod via a transmission belt.

[0008] Preferably, the threaded rod and the screw rod are both connected to a first support plate via threads, and one end of the threaded rod and the screw rod are both rotatably connected to the second support plate.

[0009] Preferably, a support rod is movably connected between the first support plate and the second support plate.

[0010] Preferably, a plurality of the heat exchange plates are movably connected to the support rod, and a plurality of springs are installed on the heat exchange plates and between the heat exchange plates.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] First, the utility model can make full use of thermal energy by arranging heat exchange plates and a box body, and transfer the heat of high-temperature flue gas to the liquid in the box body through the heat exchange plates to increase the temperature of the liquid. The temperature of the flue gas and the liquid are fully exchanged through multiple heat exchange plates, thereby improving the practicality of the device.

[0013] Secondly, the utility model can adjust the heat exchange efficiency by setting a motor and a threaded rod. The motor drives the first support plate to move toward the second support plate, thereby squeezing the heat exchange plates inward. By reducing the interval between the heat exchange plates, the contact between the heat exchange plates and the liquid in the box body is reduced, thereby achieving the effect of reducing the heat exchange rate. Conversely, the motor rotates in the opposite direction to move the first support plate away from the second support plate. The heat exchange plates are pushed by the compressed springs on the support rods. The heat exchange rate is increased by increasing the interval between the heat exchange plates, thereby controlling the heat transfer efficiency and improving the practicality of the device.

Liquid is added into the box body 1 through the liquid inlet pipe 2, and at this time, high-temperature flue gas is sent to the box body 1 through the air inlet pipe 4. The heat of the high-temperature flue gas is transferred to the liquid in the box 1 through the heat exchanger plates 12, so that the temperature of the liquid increases. The temperature of the flue gas is fully exchanged with the liquid through multiple heat exchanger plates 12. When the heat exchange efficiency needs to be adjusted, the contact between the heat exchanger plates 12 and the liquid in the box 1 is reduced by reducing the interval between the heat exchanger plates 12, thereby achieving the effect of reducing the heat exchange rate. Conversely, the heat exchange rate is increased by increasing the interval between the heat exchanger plates 12. The flue gas that has lost its temperature is discharged through the outlet pipe 5, and the heated liquid is discharged through the liquid outlet pipe 3.

[0021] Specifically, a motor 6 is fixedly mounted on one side of the box body 1 , and one end of the motor 6 is connected to a threaded rod 7 via an output shaft.

[0022] Through the above technical solution, the motor 6 drives the threaded rod 7 to rotate through the output shaft.

[0023] Specifically, one end of the threaded rod 7 is connected to a screw rod 11 via a transmission belt 10 .

[0024] Through the above technical solution, when the threaded rod 7 rotates, the screw rod 11 is driven to rotate through the transmission belt 10.

[0025] Specifically, the threaded rod 7 and the screw rod 11 are both connected to the first support plate 8 through threads, and one end of the threaded rod 7 and the screw rod 11 are both rotatably connected to the second support plate 9.

[0026] Through the above technical solution, the threaded rod 7 and the screw rod 11 rotate to drive the first support plate 8 to move toward the second support plate 9 through the threads.

[0027] Specifically, a support rod 14 is movably connected between the first support plate 8 and the second support plate 9 .

[0028] Through the above technical solution, the movable range of the first support plate 8 and the second support plate 9 is limited by the support rod 14 .

[0029] Specifically, a plurality of heat exchange fins 12 are movably connected to the support rod 14 , and a plurality of springs 13 are installed between the heat exchange fins 12 .

[0031] When in use, liquid is added into the box body 1 through the liquid inlet pipe 2. At this time, the high-temperature flue gas is sent into the heat exchange plate 12 through the air inlet pipe 4. The heat of the high-temperature flue gas is transferred to the liquid in the box body 1 through the heat exchange plate 12, so that the temperature of the liquid is increased. The temperature of the flue gas and the liquid are fully exchanged through multiple heat exchange plates 12. When the heat exchange efficiency needs to be adjusted, the motor 6 drives the threaded rod 7 to rotate through the output shaft. When the threaded rod 7 rotates, the screw rod 11 is driven to rotate through the transmission belt 10. The first support is driven by the rotation of the threaded rod 7 and the screw rod 11 through the thread. The plate 8 moves toward the second support plate 9, thereby squeezing the heat exchange plate 12 inward. By reducing the interval between the heat exchange plates 12, the contact between the heat exchange plates 12 and the liquid in the box body 1 is reduced, thereby achieving the effect of reducing the heat exchange rate. Conversely, the motor 6 rotates in the opposite direction to move the first support plate 8 away from the second support plate 9. The heat exchange plate 12 is pushed by the compressed spring 13 on the support rod 14. By increasing the interval between the heat exchange plates 12, the heat exchange rate is increased, and the flue gas that has lost its temperature is discharged through the air outlet pipe 5, and the heated liquid is discharged through the liquid outlet pipe 3.
