Description

Technical Field

[0001] The utility model belongs to the technical field of water-coal slurry stirring, and in particular relates to a water-coal slurry stirring device. Background Art

[0002] Coal-water slurry is a low-pollution, high-efficiency, pipeline-transportable coal-based fluid fuel obtained through physical processing of approximately 70% coal, 29% water and 1% additives. It can be pumped, atomized, stored and stably burned like oil. After the coal-water slurry is produced, it needs to be pumped into a storage tank for storage.

[0003] Generally, water-coal particles tend to settle easily during storage of water-coal slurry, so a stirring rod is needed for stirring. However, single stirring is often difficult to maintain the mixing degree of materials for a long time. Therefore, a water-coal slurry stirring device is needed to solve the above problem.

During this period, the aeration body can be started, and the aeration body will transport the gas to the rotating tube through the connecting tube, the air frame and the air inlet. The rotating tube will discharge the gas through the air outlet and aerate the materials in the stirring tank, so that the materials in the stirring tank can be stirred and aerated at the same time, so that the water-coal slurry particles can be mixed more fully, and when the air outlet on the rotating tube is transmitting gas, the heat at the heating rod will also be driven to dissipate to various places in the stirring tank, which will help to ensure the temperature balance of the material and prevent the material from agglomerating, thereby helping to ensure the quality of water-coal slurry storage.

[0007] As a preferred embodiment, the stirring blade is located in the stirring tank.

[0008] As a preferred implementation manner, a vertical rod is fixedly connected to the stirring blade.

[0009] As a preferred embodiment, the stirring tank is connected with an air vent.

[0010] As a preferred embodiment, one side of the stirring tank is connected to a feed pipe.

[0011] As a preferred embodiment, one side of the stirring tank is connected to a discharge pipe.

[0012] By arranging a vertical rod on the stirring blade, when the stirring blade is stirring and rotating, the vertical rod will strengthen the continuity of stirring of the upper and lower layers of materials in the stirring tank, which will help to ensure the coordination of stirring of the upper and lower materials in the stirring tank, thereby helping to improve the stirring effect.
