SUMMARY

[0003] Therefore, the utility model aims at overcoming the defects in the prior art, and provides a liquid distribution mechanism for efficiently reducing the surface dross of smelted aluminium ingot.

[0004] The utility model provides a liquid distribution mechanism for efficiently reducing the surface dross of smelted aluminium ingot, including shunt 1, both sides of shunt 1 are provided with liquid distribution piece 2, liquid distribution piece 2 is by liquid tank 2.1, a plurality of liquid outlet pipe 2.2 that communicate with the inner chamber of liquid tank 2.1 are formed, liquid outlet pipe 2.2 is evenly distributed to the one end of liquid tank 2.1 away from shunt 1 along the axis of liquid tank 2.1, the centre of liquid distribution piece 2 is provided with pivot 4, pivot 4 is keyed with sprocket 5.

[0005] Further, the cross section of the liquid tank 2.1 is connected by an isosceles trapezoid in the middle, a small square on the inside and a large square on the outside.

[0006] Further, the shunt 1 is T-shaped, and the flow channel of the longitudinal section of the shunt 1 is higher than that of the horizontal section of the shunt 1.

[0007] Further, the flow channel of the horizontal section of the shunt 1 is provided with a buckle 6 inclinedly.

[0008] Further, the flow channel of the horizontal section of the shunt 1 is provided with a recess plate 3 extending into the liquid tank 2.1.

[0009] Further, the pivot 4 is keyed with a bearing 7, and the outer ring of the bearing 7 is connected with a mounting seat 8.

[0010] The advantages of this invention are: by rotating the liquid separator, the molten aluminum at the bottom of the liquid tank flows into the mold groove through the liquid outlet pipe, thereby effectively reducing the slag on the surface of the smelted aluminum ingot; it presents a T-shape. The type of flow divider can effectively distribute the fluid in the main channel evenly to different directions. The setting of longitudinal and transverse sections helps to achieve multi-path flow. When the fluid flows from high to low, a certain pressure difference is generated, making it easier for the fluid to flow from the longitudinal section to the transverse section, thus entering each branch more smoothly. Through the rotation of the liquid distribution component, the aluminum liquid in the liquid tank flows out evenly through the liquid outlet pipe and into the mold groove. The isosceles trapezoidal area can guide the aluminum liquid to form a reasonable flow path in the tank, and the large square area can store the aluminum liquid to flow out of the liquid outlet pipe. The fastener can be used to attach a flame gun that extends into the liquid tank to prevent the aluminum liquid in the liquid tank from hardening. The concave plate setting can guide the aluminum liquid in the flow channels on the left and right sides of the flow divider into the liquid tank, avoiding the flow gap between the liquid tank and the flow channels on both sides of the flow divider. The mounting base can be installed above the moving chain block, so that the aluminum liquid from the liquid outlet pipe flows into the mold groove of the transmission chain block.
