Aiming at the problems of difficult disassembly and the like of the flow control device of the small and medium-sized casting machine in the prior art, the utility model provides the movable manual flow control device which is convenient and light in operation, can be disassembled at any time and has good flow control effect.
Fig. 1 shows a schematic front cross-sectional view of a mobile manual flow control device of the present utility model. As shown in fig. 1, the movable manual flow control device of the present utility model includes a movable bracket 1. The movable support 1 is arranged on the chute body 8. A chute 9 is arranged in the chute body 8.
Preferably, the movable support 1 comprises two vertical support plates respectively positioned at two sides of the chute 9 and a transverse support plate connected with the top ends of the two vertical support plates. Both ends of the transverse support plate can be welded to the top ends of the two vertical support plates respectively.
More preferably, the vertical support plate and the horizontal support plate are both made of steel plates. Thereby making it stronger and durable.
In the present utility model, the dimensions of the vertical and horizontal braces may be determined according to the width and depth of the chute 9.
Wherein, the bottom of each vertical support plate is provided with an inserted steel pipe 5. The inserted steel pipe 5 extends at the bottom of the vertical support plate.
Meanwhile, a chute steel plate 7 is arranged at the top of the chute body 8, and two fixed steel pipes 6 respectively positioned at two sides of the chute 9 are arranged on the chute steel plate 7.
The inserted steel pipe 5 is matched with the fixed steel pipe 6, so that the movable support 1 can be mounted on the chute body 8.
For example, the insert steel pipe 5 can be inserted into the fixed steel pipe 6 to mount the movable bracket 1 to the chute body 8.
Alternatively, the insertion steel pipe 5 and the fixed steel pipe 6 may have the same diameter, and the movable bracket 1 may be attached to the chute body 8 by inserting a pin into the insertion steel pipe 5 and the fixed steel pipe 6 after concentrically aligning the insertion steel pipe 5 and the fixed steel pipe 6.
In the present utility model, the movable bracket 1 is provided with a movable rod 2 which can move up and down relative to the movable bracket. The lower end of the movable rod 2 is connected with a flow control baffle 4. The shape of the flow control baffle 4 is the same as the cross-sectional shape of the inner surface of the chute 9 in the chute body 8. Therefore, the movable rod 2 can drive the flow control baffle 4 to move up and down, so that the flow control baffle 4 is closely matched with the inner surface of the chute 9, and the purpose of flow control is achieved.

After casting starts, as the furnace is gradually tipped over, aluminum liquid in the furnace enters the chute 9, when the liquid level of the aluminum liquid reaches about 10cm-13cm, the movable rod 2 is rotated anticlockwise to enable the flow control baffle plate 4 to ascend, and the aluminum liquid flows out of a gap between the flow control baffle plate 4 and the inner surface of the chute 9 and enters the distribution hub. Simultaneously, the movable rod 2 can be used for adjusting the height of the flow control baffle 4, so that the liquid level depth of the aluminum liquid in the distribution hub is kept stable. Thus, the aluminum output of the distribution hub is uniform, and the aluminum ingot cast by the distribution hub and the casting machine run at uniform speed is uniform in size.
The whole device of the movable manual flow control device adopts a movable connection mode, and is convenient to detach, so that the cleaning of the cast distribution hub is convenient. Moreover, the manual operation is adopted, the operation is convenient and light, and the device is very suitable for being matched with a small casting machine. Meanwhile, the high-temperature-resistant asbestos rope adopted by the aluminum liquid leakage prevention device can prevent the aluminum liquid from leaking after being tightly attached to the inner surface of the chute, and the flow control effect is good.
