Description

Technical Field

[0002] The fuel heater is a device used to heat fuel, and is mainly used in internal combustion engine power systems such as motor vehicles, ships, and engineering machinery. Its main function is to reduce the viscosity of the fuel and improve its fluidity by heating the fuel, thereby ensuring the normal supply of fuel in a low temperature environment and maintaining the normal operation of the equipment. The fuel heater is provided with a combustion chamber wall, an air supply system, and a heat conduction device. The air supply system provides air to the combustion chamber wall, and the fuel is burned in the combustion chamber wall to obtain heat, and the heat is conducted to the location where heat is needed through the heat conduction device.

[0003] The heat transfer device is mostly mounted on the combustion chamber wall on the heater, and the heat of the combustion chamber wall is transferred through heat exchange. The heat transfer device is mostly a heat exchanger. Through the flow of liquid in the heat exchanger, the liquid moves to the heat exchanger and is heated by the heater, and then moves to the position where heating is required for heating. The traditional heat exchanger heats the pipeline with the hot air generated when the fuel is burned, and then the hot air is discharged. In this process, there may be a large amount of heat waste due to the position of the pipeline in the heat exchanger or the flow of hot air, resulting in a large amount of fuel consumption during use.

[0023] like Figure 4~Figure 6 As shown, the dust removal assembly includes a dust removal pipeline 12, a water inlet channel 13, a water outlet channel 14 and a dust removal channel 15. The dust removal pipeline 12 is fixedly arranged on the heat exchange chamber 6, and the dust removal pipeline 12 is connected to the opening on the heat exchange chamber 6. The water inlet channel 13 is arranged on the dust removal pipeline 12, and the water inlet channel 13 is not connected to the opening on the heat exchange chamber 6.

When the output end of the driving cylinder 20 is extended, it pushes the sealing cover 17 to rotate 90 degrees. At this time, the baffle plate 18 rotates to be perpendicular to the dust removal pipe 12. At the same time, the blocking block 21 rotates with the sealing cover 17 and moves toward the combustion chamber wall 3 under the action of the threaded rod 19 until it contacts the combustion chamber wall 3. At this time, the blocking block 21 is close to the dust removal pipe 12, and the hot air enters the gap between the combustion chamber wall 3 and the heat exchange chamber 6 through the side of the baffle plate 18 away from the blocking block 21.

When the output end of the driving cylinder 25 is extended, the air baffle plate 22 is pushed into the exhaust duct 11. At the same time, the output end of the driving cylinder 25 slides in the turning groove 24 to drive the air baffle plate 23 to slide in the dust removal channel 15, so that the exhaust channel is closed and the dust removal channel 15 is opened. The same is true when the output end of the driving cylinder 25 is shortened.

[0026] In summary, the working principle of this energy-saving double water chamber heat exchanger is: The heater 1 sends air into the center of the combustion chamber wall 3 through the air inlet 2 to react with the flame. The heated air enters the gap between the heat exchange chamber 6 and the combustion chamber wall 3, and conducts the heat to the heat exchange tube 1 4 and the heat exchange tube 2 5, and conducts the heat to the heat exchange chamber 6 through the heat exchange plate 7. The hot air is discharged through the air guide duct 10 and the exhaust duct 11. The output end of the driving cylinder 1 20 is extended to push the sealing plate to rotate.
