Description

Technical Field

[0001] The utility model relates to the technical field of heat storage, in particular to a heat storage device which is easy to clean. Background Art

[0002] High-temperature exhaust gas is common in the industrial field, such as casting, metallurgy and heat treatment industries. The energy consumption is high and the exhaust gas produced carries a large amount of heat. Direct discharge or exhaust gas treatment will result in the loss of this heat. The heat can be absorbed and reused through heat storage devices to reduce losses.

[0003] Most existing heat storage devices use heat storage balls to absorb heat from exhaust gas and store heat. When the airflow flows in the opposite direction, the heat storage balls are used to release heat, heat the airflow, and improve the utilization rate of heat, thereby reducing energy consumption. However, exhaust gas often contains dust. During the contact between the exhaust gas and the heat storage balls, dust is easily attached to the heat storage balls, reducing the contact area between the heat storage balls and the exhaust gas, reducing the heat transfer rate, and requiring cleaning and maintenance. Most existing heat storage devices are sealed structures, and the number of heat storage balls is large, so disassembly and maintenance are very cumbersome and need to be improved. Utility Model Content

[0007] Wherein, a bracket is arranged below the shell.

[0008] Wherein, a discharge valve is arranged at the bottom of the ash hopper.

[0009] Wherein, a rotating shaft penetrating the rotating drum is arranged in the shell.

[0011] The rotating cage and the honeycomb partition are densely covered with pores, and the diameter of the pores is smaller than the diameter of the heat storage ball.

[0012] The beneficial effects of the utility model include: a heat storage device which is easy to clean, wherein the exhaust gas enters the shell through the air inlet pipe joint, and when passing through the heat storage balls in the rotating cage, the heat storage balls absorb the heat in the exhaust gas for heat storage, and when the exhaust gas volume is large, the blades are blown by the exhaust gas to drive the rotation of the rotating cage, and when the exhaust gas volume is small, the rotating shaft can be rotated by a reduction motor or a manual turntable to drive the rotation of the rotating cage to realize the rolling of the heat storage balls, which can increase the contact area between the heat storage balls and the exhaust gas, and can also perform mutual friction between the heat storage balls to remove dust on the surface, thereby realizing rapid cleaning, ensuring the heat transfer rate of the heat storage balls, and improving the heat storage effect.
