In order to facilitate demolding of the aluminum ingot and the drain box and convenient lifting after solidification of the waste aluminum liquid, the present embodiment provides a drain box, and details of the present embodiment are described in detail below with reference to fig. 1 to 3.
Example 1
As shown in fig. 1 and 2, the drain box comprises a box body 1 and a hook body 2. Wherein the box body 1 is concavely provided with a containing groove 11 for storing aluminum liquid, and the area of a notch of the containing groove 11 is gradually increased along the direction away from the bottom of the self groove. The lifting hook main body 2 comprises a vertical rod piece 21 and an inclined rod piece 22 which are connected, a lifting ring 3 is arranged at the connection transition part of the vertical rod piece 21 and the inclined rod piece 22, a plurality of hook pieces 4 are arranged on the inclined rod piece 22 at intervals along the length direction of the inclined rod piece 22, and the hook pieces 4 extend along the vertical direction. At least one pair of hook bodies 2 is placed at the notch of the accommodating groove 11, and the lower surface of the inclined rod 22 is attached to the inner wall surface of the accommodating groove 11. Specifically, the lower surface of the inclined lever 22 is inclined at the same angle as the inner wall surface of the accommodating groove 11.
In short, in the drainage box provided by the embodiment, the lifting ring 3 is fixedly arranged on the lifting hook main body 2, so that the lifting hook main body 2 is conveniently lifted by the lifting appliance; a plurality of hook pieces 4 are arranged on the inclined rod piece 22 at intervals, and the hook main body 2 is clamped and placed at the notch of the accommodating groove 11 of the box body 1. When the aluminum liquid starts to drain, the aluminum liquid enters the box body 1 of the drain box, after the aluminum liquid is solidified, the lifting ring 3 is hooked by a lifting appliance, then an aluminum ingot is lifted, and after the aluminum ingot is arranged, the lifting hook main body 2 is detached for reuse. After the aluminum liquid is solidified into an aluminum ingot, the hook piece 4 is in a state of being inserted into the aluminum ingot, so that the connection stability of the aluminum ingot and the lifting hook main body 2 is improved; the area of the notch of the accommodating groove 11 is gradually increased along the direction away from the bottom of the accommodating groove, so that the aluminum ingot can be conveniently demolded; because the lower surface of the inclined rod piece 22 is attached to the inner wall surface of the accommodating groove 11, the aluminum liquid is prevented from entering the position between the lower surface of the inclined rod piece 22 and the inner wall surface of the accommodating groove 11, the inclined rod piece 22 cannot be completely wrapped by the aluminum ingot, and the lifting hook main body 2 is convenient to separate from the aluminum ingot; at least one pair of lifting hook main bodies 2 are matched for use, so that the aluminum ingot is stressed in two directions, and the aluminum ingot is prevented from deflecting when being lifted and conveyed.
Further, the end of the hook 4 remote from the tilt lever 22 is provided with a wedge head 41. A wedge-shaped head 41 is arranged at the upper part of the hook piece 4, so that the hook piece 4 can be conveniently and quickly separated from an aluminum ingot.
