[0003] However, the prior art still has the following deficiencies: the existing water pumping devices often face the problem of unsatisfactory atomization effect, which leads to low utilization of water resources, because water cannot be effectively decomposed into fine particles, making it inconvenient to fully cover the interior of the blast furnace, resulting in a waste of water resources. In addition, due to the lack of precise control means, it is difficult for the water pumping device to pump water according to the required amount and time, and the amount of water pumped may be too much or too little, which is not conducive to better control of the temperature inside the blast furnace.

[0004] Therefore, a blast furnace top water pumping device for lowering the material surface is urgently needed to solve the above problems. Utility Model Content
