Description

Technical Field

[0001] The present application relates to the technical field of hydrogen heating, and in particular to a hydrogen heating type asphalt mixing station. Background Art

[0002] Asphalt mixing plants are indispensable and important equipment in road construction. They are mainly used to produce various types of asphalt mixtures to meet the paving needs of roads, airport runways and other roads. In the asphalt mixing process, the heating of the mixture is a crucial link, which directly affects the quality of the asphalt mixture and the construction effect. Traditional asphalt mixing plants mostly use fuel oil, gas or electric heating methods, but these methods will generate a lot of waste gas and waste residue during the heating process, causing environmental pollution.

[0003] In recent years, with the global emphasis on clean energy and sustainable development, more and more industries have begun to seek clean energy solutions to replace traditional energy. As an efficient and clean energy source, hydrogen only produces water during its combustion process without any harmful substances, so it is highly environmentally friendly and sustainable.

[0004] Applying hydrogen to the heating system of an asphalt mixing plant can achieve clean and efficient heating of asphalt mixtures. In an asphalt mixing plant, hydrogen and oxygen are mixed and burned in the combustion chamber to produce a high-temperature flame, which transfers heat to the asphalt mixture through a heat exchanger to reach the required heating temperature. Compared with traditional fuel oil and gas heating methods, hydrogen heating has significant advantages.

[0005] In the heating process of the asphalt mixing plant, in order to ensure efficient and stable combustion, oxygen and hydrogen must be mixed before combustion, and the mixed gas is then sent to the combustion chamber, where it is burned to produce a high-temperature flame. In this process, the supply and control of oxygen and hydrogen are crucial. If the mixed gas in the combustion chamber has been consumed, and the new oxygen and hydrogen have not yet been mixed and delivered to the combustion chamber, the heat transferred to the asphalt mixing plant will become uneven, resulting in poor heating effect of the asphalt mixture. Summary of the invention

[0006] In order to improve the heating effect on asphalt mixture, the present application provides a hydrogen heating asphalt mixing station.

[0008] With the above technical solution, hydrogen and oxygen are introduced into the mixing area through the gas station respectively. After the mixing is completed in the mixing area, the mixed gas of oxygen and hydrogen passes through the partition and enters the storage area for temporary storage. Before combustion, the storage area is filled with hydrogen and oxygen mixed gas, and the newly mixed mixed gas is subsequently added to the storage area, thereby continuously transporting the mixed gas of oxygen and hydrogen into the combustion chamber through the storage area, reducing the occurrence of mixed gas vacancies in the combustion chamber, thereby improving the heating effect of the asphalt mixture.

[0011] By adopting the above technical solution, when the stirring assembly is mixing hydrogen and oxygen, the first notch and the second notch are aligned; after the hydrogen and oxygen are mixed, the first notch and the second notch are not aligned, so that the push plate pushes the mixed hydrogen and oxygen toward the direction close to the partition, thereby overcoming the damping of the elastic member, so that the mixed hydrogen and oxygen enter the storage area.

[0013] By adopting the above technical solution, during the linkage rotation around its own central axis, the linkage ring is caused to rotate around its own central axis through the connecting rod, and at the same time the connecting rod causes the stirring ring to rotate around the central axis of the linkage ring, so that the stirring ring stirs the hydrogen and oxygen in the mixing zone, thereby accelerating the mixing of hydrogen and oxygen and improving the degree of mixing of hydrogen and oxygen.

[0014] Optionally, the driving assembly includes a driving screw and a guide rod, the driving screw passes through the driving ring and the two are threadedly connected, the end of the driving screw is rotatably connected to the air distribution chamber, the driving screw rotates around its own central axis, and a driving motor for driving the driving screw to rotate is fixedly installed on the air distribution chamber, the guide rod passes through the driving ring and the two are slidably adapted, and the end of the guide rod is fixed to the inner wall of the air distribution chamber.

[0015] By adopting the above technical solution, the drive motor is started to rotate the drive screw, thereby driving the screw to make the drive ring slide along the guide rod. The movement direction of the drive ring is changed by changing the direction of the output shaft of the drive motor, thereby making the stirring ring move along the guide rod in the mixing zone, and at the same time achieving the effect of the push plate pushing the mixed hydrogen and oxygen into the storage area.

[0016] Optionally, the first transmission assembly includes a first transmission gear, a second transmission gear and a transmission gear ring, the first transmission gear is sleeved on the guide rod, and the first transmission gear is rotatable around its own center axis and connected to the driving ring, the inner wall of the first transmission gear is fixed with a linkage block, the outer wall of the guide rod is spirally provided with a linkage groove that is slidably matched with the linkage block, the second transmission gear is rotatable around its own center axis and connected to the driving ring, the second transmission gear is meshed with the first transmission gear, the transmission gear ring is fixed to the linkage ring, and the transmission gear ring is meshed with the second transmission gear.

[0017] By adopting the above technical solution, during the sliding of the driving ring along the guide rod, the guide rod slides in the linkage groove through the linkage block, causing the first transmission gear to rotate around its own center axis. The first transmission gear causes the transmission gear ring to rotate around its own center axis through the second transmission gear, and thus the transmission gear causes the linkage ring to rotate, thereby achieving the effect of driving the linkage ring to rotate during the sliding process of the driving ring.

[0018] Optionally, a cavity is provided in an annular shape inside the fixing ring; One end of the connecting rod is rotatably connected to the rotating ring, and the other end of the connecting rod is rotatably connected to the linkage ring.

[0019] By adopting the above technical solution, when the connecting rod rotates around the central axis of the driving ring, the connecting rod causes the linkage bevel gear to roll on the linkage bevel gear ring, thereby causing the connecting rod to rotate around its own central axis. As a result, the connecting rod causes the stirring ring to move along the length direction of the connecting rod through the second transmission assembly, thereby enhancing the stirring intensity of the stirring ring on hydrogen and oxygen.

At this time, the gas station transports oxygen and hydrogen to the mixing area through the gas delivery pipeline; when the air pressure sensor detects that the air pressure in the mixing area is higher than the reference value, the air pressure sensor transmits a stop signal to the regulating valve, thereby closing the regulating valve. At this time, the gas station stops transporting hydrogen and oxygen to the mixing area.

[0024] Optionally, a flow balancing valve is installed on the air outlet pipeline to control the flow of the air outlet pipeline to maintain stability.
