Description

Technical Field

[0001] This utility model belongs to the technical field of heating furnaces for hydrogen production and storage materials, and specifically relates to a cooling and stirring structure for a heating furnace for hydrogen production and storage materials. Background Technology

[0002] Hydrogen energy, as an efficient and clean energy carrier, has received widespread attention in recent years. The production of hydrogen storage materials is a crucial step in hydrogen energy utilization, making the optimization of their preparation process essential. The heating furnace is a vital piece of equipment in the hydrogen storage material production process, and the cooling and stirring treatment of the spun belts within the furnace plays an indispensable role in the entire preparation process.

[0003] In existing hydrogen production and storage material heating furnace technologies, the cooling and stirring process of the spinning strips has several shortcomings. Traditional cooling methods are mostly natural cooling or simple air cooling, which results in a slow cooling rate for the spinning strips detached from the cooling rollers. Because the spinning strips remain at high temperatures for too long, the microstructure of the material is easily altered, thus affecting its hydrogen storage performance. For example, some metal alloy hydrogen storage materials experience grain growth and compositional segregation during slow cooling, leading to reduced hydrogen storage capacity and poorer cycle stability. Furthermore, existing cooling devices are fixed structures and cannot effectively break up the spinning strips. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a cooling and stirring structure for a hydrogen production and storage material heating furnace.

[0005] This utility model provides a cooling and stirring structure for a hydrogen production and storage material heating furnace, used for cooling and stirring the belts of the heating furnace body. It includes a cooling fan located outside the heating furnace body and a cooling component located inside the heating furnace body, the cooling fan and the cooling component being connected via an air inlet pipe; a support component is provided outside the air inlet pipe, the support component being connected to the cooling component; a cylinder is provided at the top of the heating furnace body, the output end of the cylinder being connected to the support component, used to drive the cooling component to perform vertical movement.

[0006] A further embodiment is that the support assembly includes a first fixed plate sleeved on the outside of the air inlet pipe and a second fixed plate disposed on the top of the air inlet pipe. The cooling assembly, the first fixed plate, and the second fixed plate are coaxially arranged. A plurality of support tubes are disposed around the first fixed plate. The support tubes pass through the first fixed plate and are slidably connected to the first fixed plate. The top of the support tube is connected to the second fixed plate, and the bottom of the support tube is connected to the cooling assembly. The output end of the cylinder is connected to the second fixed plate.

[0007] A further embodiment is that a water-cooling plate is provided inside the heating furnace body, and the water-cooling plate is located at the bottom of the heating furnace body and is rotatably connected to the heating furnace body.

[0008] A rotating motor is installed at the bottom of the water-cooling plate to drive the water-cooling plate to make circular motion.

[0009] A further embodiment is that the cooling component includes an air outlet duct and a distribution plate. The air outlet duct is connected to the distribution plate, the bottom of the support pipe is connected to the distribution plate, and the outlet duct is slidably connected to the inlet duct. The distribution plate has a hollow structure and several guide plates are provided inside the distribution plate to divide the distribution plate into several cooling chambers. A cooling branch pipe is provided on the outside of each cooling chamber.

[0010] A further embodiment is that stirring teeth are fixedly installed on the outer side of the cooling pipe.

[0011] A further embodiment is that the bottom of the stirring teeth is a crushing head, which has a sharp tip for crushing the conveyor belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention incorporates a cooling component within the heating furnace body. This component, connected to an external cooling fan, further accelerates the cooling of the strips detached from the cooling rollers. A cylinder connected to the cooling component allows for its raising and lowering, breaking up and agitating the strips. This significantly increases the specific surface area of ​​the material, providing more surface sites for hydrogen adsorption and effectively improving hydrogen storage efficiency. The agitation process promotes uniform dispersion of the particles formed from the broken strips, preventing component segregation and ensuring the consistency of the material's internal structure and properties. This also results in a more uniform reaction during hydrogen absorption and desorption, improving the stability and cycle life of the hydrogen storage material.

[0014] This invention also includes a water-cooling plate inside the heating furnace body, which works in a circular motion with the help of a rotating motor. On the one hand, the water-cooling medium absorbs the heat conducted by the spinning belt, and on the other hand, the dynamic contact expands the cooling area. Moreover, the rotation of the water-cooling plate, combined with the stirring teeth, further improves the stirring efficiency, shortens the cooling time, and enhances the uniformity of cooling.

[0015] The guide plate inside the distribution plate of this utility model divides it into multiple cooling chambers, so that the cold air is evenly distributed to each cooling pipe, avoiding airflow turbulence and ensuring that the cooling rate of the belt strips in each area is consistent during the cooling process, thereby improving the stability of material quality. By designing the crushing head at the bottom of the stirring teeth on the periphery of the distribution plate as a sharp tip, the principle of concentrated stress at the tip is used to produce a highly efficient crushing effect on the belt strips, which can quickly crush the belt strips to the target particle size and improve crushing efficiency.

A cooling roller 7 is also provided inside the heating furnace body 1 for rapid heat exchange of molten metal. The molten metal in the crucible 8 is poured onto a high-speed rotating cooling roller 7, where intense heat exchange causes the molten metal to solidify into a thin sheet in a very short time. Specifically, the cooling and stirring structure of the hydrogen storage material heating furnace includes a cooling fan 3 located outside the heating furnace body 1 and a cooling component 5 located inside the heating furnace body 1. The cooling fan 3 and the cooling component 5 are connected by an air inlet pipe 4. A support component is provided outside the air inlet pipe 4 and is connected to the cooling component 5. A cylinder 16 is provided on the top of the heating furnace body 1, and the output end of the cylinder 16 is connected to the support component to drive the cooling component 5 to move vertically.

The output end of the cylinder 16 is connected to the second fixing plate 15.

[0023] To further enhance the cooling and stirring effect, a water-cooled plate 6 is installed inside the heating furnace body 1. The water-cooled plate 6 is located at the bottom of the heating furnace body 1 and is rotatably connected to it. A rotating motor is installed at the bottom of the water-cooled plate 6 to drive it in a circular motion. When the cylinder 16 drives the support assembly to descend, the water-cooled plate 6 and the cooling assembly rotate relative to each other as the water-cooled plate 6 rotates, further stirring the belt.
