Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid conveying technology, and in particular to an anti-overflow device for aluminum liquid conveying. Background Technology

[0002] Aluminum molten material transport refers to the process of transferring liquid aluminum from one location to another for further processing or treatment during aluminum processing. This process typically uses chute pipes, a common method that utilizes gravity to allow the molten aluminum to flow through specially designed chute pipes from a higher to a lower elevation. The chute pipes are usually made of refractory materials to withstand the corrosion of high-temperature molten aluminum. This method is suitable for short-distance transport scenarios with relatively large elevation differences, such as transporting molten aluminum from a furnace to a casting machine.

[0003] A search of Chinese patent publication number "CN212398099U" reveals "a chute" that can prevent molten zinc alloy from spilling onto the ground, thus avoiding contamination of the zinc alloy and reducing energy consumption; it can also prevent molten zinc alloy from spilling, effectively avoiding the safety hazard of employees being burned by high-temperature molten metal; this device has a simple structure, is easy to operate, and has low manufacturing cost.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the pipeline is in use, under complex conditions such as pipeline routing and slope settings, the aluminum liquid will accumulate during the flow process, which can easily lead to overflow. The reliability is insufficient and needs to be improved. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an overflow prevention device for aluminum molten material transportation, solving the technical problem of insufficient reliability in existing chute pipelines.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An overflow prevention device for conveying molten aluminum includes an overflow prevention chute pipe, wherein square grooves are symmetrically opened inside the overflow prevention chute pipe, and overflow grooves are opened through both square grooves, and a first inclined surface is opened on the inner wall of both overflow grooves.

[0010] Both overflow channels are fixedly equipped with a diversion and anti-overflow structure at their lower ends;

[0011] The diversion and overflow prevention structure includes liquid inlet plates, each of which has a third inclined surface inside. Both third inclined surfaces are parallel to the first inclined surface. Each of the two square groove sidewalls has a first connecting groove through it. The overflow prevention chute pipe sidewall is symmetrically provided with auxiliary overflow chute pipes.

[0012] Preferably, both auxiliary overflow chute pipes have a gas dissipation groove extending through their upper ends. The auxiliary overflow chute pipes have a second inclined surface inside and a second connecting groove extending through them. The anti-overflow chute pipe and the auxiliary overflow chute pipe are fixedly installed. Both first connecting grooves are parallel to the second connecting groove and communicate with the second connecting groove. The two first inclined surfaces, the second inclined surfaces, and the second connecting grooves are all in a smooth, stepless communication state.

[0013] Preferably, a reinforcing rib group is symmetrically fixedly installed between the two auxiliary overflow chute pipes, and a splash guard is fixedly installed at the upper and lower ends of the two reinforcing rib groups. A discharge chute pipe is provided on the side wall of the anti-overflow chute pipe away from the auxiliary overflow chute pipe, and the discharge chute pipe is connected to the anti-overflow chute pipe.

[0014] (III) Beneficial Effects

[0015] Firstly, by setting up an overflow chute pipe and opening an overflow trough inside the square trough, if there is an accumulation of aluminum liquid during the subsequent transportation of aluminum liquid through the overflow chute pipe, the aluminum liquid can enter the square trough through the inlet plate and slide to the side of the first phase channel, thereby diverting it into the square trough and thus preventing the aluminum liquid from overflowing and improving reliability.

[0016] Secondly, by setting an auxiliary overflow chute pipe on the side wall of the overflow chute pipe, the aluminum liquid discharged through the square chute can enter the auxiliary overflow chute pipe through the first phase passage and the second phase passage for discharge. At the same time, since the aluminum liquid slides on a smooth, stepless surface during discharge, the occurrence of splashing can be reduced. Attached Figure Description

[0024] This application provides an anti-overflow device for aluminum molten material transportation, effectively solving the technical problem of insufficient reliability in existing chute pipes. By setting up an anti-overflow chute pipe with an overflow channel inside the square trough, if aluminum molten material accumulates during subsequent transportation, it can enter the square trough through the inlet plate and slide towards the first phase channel, thus diverting it into the square trough and preventing overflow, thereby improving reliability. Furthermore, by setting an auxiliary overflow chute pipe on the side wall of the anti-overflow chute pipe, the aluminum molten material discharged from the square trough can enter the auxiliary overflow chute pipe through the first and second phase channels for discharge. At the same time, since the aluminum molten material slides on a smooth, stepless surface during discharge, splashing is also reduced.

[0025] Example

[0026] like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient reliability of existing chute pipelines. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the present invention provides an anti-overflow device for aluminum liquid transportation, including an anti-overflow chute pipe 11, with square grooves 24 symmetrically opened inside the anti-overflow chute pipe 11, and overflow grooves 12 penetrating through the two square grooves 24, and a first inclined surface 13 opened on the inner wall of the two overflow grooves 12.

[0028] Both overflow troughs 12 are fixedly equipped with diversion and overflow prevention structures at their lower ends;

[0029] The diversion and overflow prevention structure includes an inlet plate 14, with a third inclined surface 25 inside each of the two inlet plates 14. The two third inclined surfaces 25 are parallel to the first inclined surface 13. A first connecting groove 15 is opened through the side wall of each of the two square grooves 24. An auxiliary overflow chute pipe 16 is symmetrically provided on the side wall of the overflow prevention chute pipe 11.

[0030] By setting up an anti-overflow chute pipe 11 and opening an overflow trough 12 inside the square trough 24, if aluminum liquid accumulates during the subsequent aluminum liquid transportation process of the anti-overflow chute pipe 11, the aluminum liquid can enter the square trough 24 through the liquid inlet plate 14 and slide towards the first connecting trough 15 side, thereby diverting it into the square trough 24 and preventing the aluminum liquid from overflowing, thus improving reliability.

[0031] Both auxiliary overflow chute pipes 16 have a gas dissipation groove 17 extending through their upper ends. The auxiliary overflow chute pipe 16 has a second inclined surface 18 inside and a second connecting groove 19 extending through its interior. The anti-overflow chute pipe 11 and the auxiliary overflow chute pipe 16 are fixedly installed. Both first connecting grooves 15 are parallel to the second connecting groove 19 and are connected to the second connecting groove 19. The two first inclined surfaces 13, the second inclined surfaces 18, and the second connecting groove 19 are all in a smooth, stepless connected state.

[0032] By setting an auxiliary overflow chute pipe 16 on the side wall of the overflow chute pipe 11, the aluminum liquid discharged through the square trough 24 can enter the auxiliary overflow chute pipe 16 through the first phase passage 15 and the second phase passage 19 for discharge. At the same time, since the aluminum liquid slides on a smooth, stepless surface during discharge, the occurrence of splashing can be reduced.

[0033] Two auxiliary overflow chute pipes 16 are symmetrically fixedly installed with reinforcing rib groups 21. Splash plates 22 are fixedly installed at the upper and lower ends of the two reinforcing rib groups 21. A discharge chute pipe 23 is provided on the side wall of the anti-overflow chute pipe 11 away from the auxiliary overflow chute pipe 16. The discharge chute pipe 23 is connected to the anti-overflow chute pipe 11.

[0034] By installing reinforcing ribs 21 between the auxiliary overflow chute pipes 16, the reinforcing ribs 21 can block splashed aluminum liquid when the overflow chute pipe 11 discharges aluminum liquid, thereby reducing the problem of aluminum liquid splashing out of the equipment. At the same time, the reinforcing ribs 21 can also improve the strength between the auxiliary overflow chute pipes 16.

[0035] Working principle:

[0036] In use, when the discharge chute pipe 23 discharges molten aluminum into the anti-overflow chute pipe 11, if molten aluminum accumulates inside the anti-overflow chute pipe 11, the flow of molten aluminum will first enter the square groove 24 through the third inclined surface 25 inside the inlet plate 14. At the same time, the molten aluminum will move to the side of the first connecting groove 15 and enter the second inclined surface 18 inside the auxiliary overflow chute pipe 16 for discharge, thereby achieving the effect of diverting and assisting discharge and preventing overflow.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
