the label is: the device comprises a groove-shaped chute 1, a support frame 2, a movable roller assembly 3, a protective baffle 4 and a handle 5.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figure 1, the utility model discloses a chute device for adding electrolyte, including cell type chute 1, support frame 2, removal wheel components 3, cell type chute 1 sets up on support frame 2, and the right-hand member of cell type chute 1 is the exit end, and support frame 2 sets up on removing wheel components 3.

When electrolyte needs to be added into an electrolytic tank with a lower electrolyte level, firstly, after an aluminum outlet of the electrolytic tank is cleaned, the moving roller assembly 3 is pushed, the outlet end of the groove-shaped chute 1 extends into the aluminum outlet, then, the lifting crown block is controlled to lift the ladle filled with the electrolyte in place, finally, an operator slowly shakes the ladle, the electrolyte in the ladle flows into the electrolytic tank along the chute until the electrolyte level in the electrolytic tank reaches the standard, and after the electrolyte adding work is finished, the chute device only needs to be moved away. Use the utility model discloses a chute device, simple structure can reduce the clearance requirement to the electrolysis trough aluminium mouth, requires required time to reduce 70% at least for current clearance, also makes things convenient for operating personnel to carry out electrolyte and adds work, is showing to improve electrolyte and adds efficiency, reduces the electrolyte volume of solidifying in the two-man ladle to reduce the loss volume of electrolyte, but also can effectively reduce the possibility that takes place the electrolyte and splash and injure people, improve operating personnel's security.

Because the environment of the aluminum electrolysis production workshop is poor, the stability of the electrolyte is also high, and in order to ensure the service time and the use safety of the whole chute device, the chute-shaped chute 1, the support frame 2 and the moving roller component 3 are preferably made of steel, such as steel plates with the thickness of 10 mm. In order to facilitate the addition of the electrolyte into the electrolytic cell, the electrolyte is preferably fed into the electrolytic cell from the left end to the right end of the trough-shaped chute 1, the right end of the trough-shaped chute 1 is provided as an outlet end, and the cross-sectional width of the trough-shaped chute 1 gradually decreases from left to right. In order to prevent the electrolyte in the groove-shaped chute 1 from flowing backwards and causing safety accidents, a protective baffle 4 is arranged at the left end part of the groove-shaped chute 1, and the left end part of the groove-shaped chute 1 is sealed through the protective baffle 4, so that the electrolyte can only go out from the right end part of the groove-shaped chute 1. In order to further facilitate the electrolyte to be added into the electrolytic cell along the groove-shaped chute 1, the groove-shaped chute 1 is in an inclined state when the electrolytic cell is used, the inclined lower end of the groove-shaped chute 1 is an outlet end, the groove-shaped chute 1 can swing up and down on the support frame 2, and an operator can adjust the inclined angle of the groove-shaped chute 1 according to actual conditions.

In order to more conveniently move the whole chute device, the moving roller assembly 3 comprises a roller, and the roller is a universal roller. Further, the chute comprises a handle 5, and the handle 5 is connected and arranged on the left side of the chute 1. The length of the handle 5 is adjustable, i.e. the handle 5 is a telescopic handle. When the whole chute device is moved, the length of the handle 5 is in a longer state; after the outlet end of the groove-shaped chute 1 extends into the aluminum outlet, the length of the handle 5 is reduced, so that the phenomenon that the groove-shaped chute 1 is shifted to influence the operation of adding electrolyte due to the fact that the handle is collided in the operation process of adding the electrolyte is reduced. The length of the handle 5 can be adjusted, so that the handle is more convenient for operators with different heights to use. In order to reduce the occurrence of slippage for the operator when moving the entire chute arrangement, the handle 5 may be provided with anti-slip protrusions.
