Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting launders, in particular to a horizontal-flow slag-blocking copper liquid launder. Background Art

[0002] The original launder for copper liquid is in a long strip shape. When the copper liquid enters the narrow launder, there will be an impact between the copper liquid and the launder, and the flow velocity changes, forming turbulent tumbling. Copper slag and other impurities will be involved in the copper liquid and cannot form floating slag on the surface of the copper liquid, so that the impurities in the copper liquid cannot be effectively removed. As a result, the impurities contained in the copper liquid rise when standing in the holding furnace and condense on the side wall of the holding furnace. During production, the condensed cold copper impurities flake off and mix into the copper liquid, causing process abnormalities. There is an urgent need for a launder that can relieve the turbulence of the copper liquid to improve the quality of copper production. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a horizontal-flow slag-blocking copper liquid launder to solve the problem that the copper liquid forms turbulent tumbling after entering the launder, and copper slag and other impurities will be involved in the copper liquid, so that the impurities in the copper liquid cannot be effectively removed.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A horizontal-flow slag-blocking copper liquid launder includes a launder body. A flow-weakening structure, a horizontal-flow mechanism and a slag-blocking brick are sequentially arranged in the flow channel of the launder body along the direction of the copper liquid flow channel. Among them,

[0006] The flow-weakening structure is composed of a plurality of rows of flow-weakening comb guide plates arranged in rows;

[0007] The horizontal-flow mechanism includes a lifting assembly and a smoothing plate. The lifting assembly is installed on the launder body. The smoothing plate is rotatably installed on the lifting end of the lifting assembly, and the height of the smoothing plate is adapted to the height of the copper liquid.

[0008] A further technical solution is that the flow-weakening comb guide plates are at least three rows and are arranged in a staggered manner. The first two rows of flow-weakening comb guide plates are inclined and the inclination directions are opposite, and the last row of flow-weakening comb guide plates is arranged parallel to the flowing direction of the copper liquid.

[0009] A further technical solution is that the lifting assembly includes a cross bar, a lifting plate and a screw rod. The cross bar is installed across the launder body. The screw rod is vertically arranged and is installed on the cross bar through a threaded structure. The lifting plate is horizontally arranged and is rotatably connected to the bottom of the screw rod. A guide post slidably connected to the cross bar is arranged on the lifting plate, and the smoothing plate is rotatably installed on the lifting plate.

[0010] A further technical solution is that a torsion spring is arranged at the rotational connection between the smoothing plate and the lifting plate.

[0011] A further technical solution is that a plurality of feeding racks are arranged at the lower part of the leveling plate.

[0012] A further technical solution is that the slag retaining brick is suspended and horizontally installed in the flow channel of the runner body, and the top of the slag retaining brick is higher than the liquid level of the copper liquid.

[0025] Embodiment 1:

[0026] As shown in this embodiment Figure 1 and Figure 2 a horizontal slag-blocking copper liquid flow channel includes a flow channel body 1. A slow-flow structure 2, a horizontal flow mechanism 3 and a slag-blocking brick 4 are sequentially arranged in the flow channel of the flow channel body 1 along the copper liquid flow channel direction. Among them, the slow-flow structure 2 is composed of a plurality of slow-flow comb guide plates 5 arranged in rows; the horizontal flow mechanism 3 includes a lifting assembly 6 and a flattening plate 7. The lifting assembly 6 is installed on the flow channel body 1, the flattening plate 7 is rotatably installed on the lifting end of the lifting assembly 6, and the height of the flattening plate 7 is adapted to the height of the copper liquid.

[0027] The copper liquid is in accordance with Figure 1Flow in the direction of the arrow. The turbulent molten copper first passes through the flow-attenuating structure 2. Multiple rows of flow-attenuating and guiding plates 5 arranged in a row will guide the disorderly flow direction of the molten copper, making the flow direction of the molten copper neat and consistent. Then the molten copper passes through the laminar flow mechanism 3. The flattening plate 7 flattens the waves of the molten copper to prevent the waves from entraining the dross into the molten copper. The lifting assembly 6 can adjust the height of the flattening plate 7 to adapt to the liquid level height of the molten copper. Finally, the molten copper passes through the slag-blocking brick 4, and the slag-blocking brick 4 blocks the copper slag floating on the liquid surface of the molten copper to facilitate subsequent slag cleaning work.

[0028] Preferably, there are at least three rows of flow-attenuating and guiding plates 5 and they are arranged in a staggered manner. The first two rows of flow-attenuating and guiding plates 5 are inclined and the inclination directions are opposite. The last row of flow-attenuating and guiding plates 5 is arranged parallel to the flow direction of the molten copper.

[0029] The three rows of flow-attenuating and guiding plates 5 arranged as above can not only play a role in combing the flow direction of the molten copper, but also slow down the flow rate of the molten copper. The last row of flow-attenuating and guiding plates 5 standardizes the final flow direction of the molten copper, making it consistent with the flow channel of the chute body 1.

[0030] Preferably, the lifting assembly 6 includes a cross bar 8, a lifting plate 9 and a screw 10. The cross bar 8 is installed across the chute body 1. The screw 10 is arranged vertically and is installed on the cross bar 8 through a threaded structure. The lifting plate 9 is arranged horizontally and is rotatably connected to the bottom of the screw 10. A guide post 11 slidably connected to the cross bar 8 is arranged on the lifting plate 9. The flattening plate 7 is rotatably installed on the lifting plate 9.

[0031] The lifting assembly 6 is a conventional lifting mechanism. The rotation of the screw 10 is used to drive the lifting plate 9 to move up and down in the vertical direction to adjust the height of the flattening plate 7.

[0032] Preferably, a torsion spring is arranged at the rotational connection between the flattening plate 7 and the lifting plate 9.

[0033] The torsion spring can provide a certain amount of torsion to the flattening plate 7 to help the flattening plate 7 better flatten the waves of the molten copper.

[0034] Embodiment 2:

[0035] Based on the above embodiment, in this embodiment as Figure 3 shown, a plurality of feeding racks 12 are arranged at the lower part of the flattening plate 7.

[0036] The feeding racks 12 can not only help the flattening plate 7 better cut into the molten copper, but also play a role in shunting. The gaps between the feeding racks 12 facilitate the passage of the molten copper and reduce the impact of the molten copper waves on the flattening plate 7.

[0037] Preferably, the slag-blocking brick 4 is suspended and horizontally installed in the flow channel of the chute body 1, and the top of the slag-blocking brick 4 is higher than the liquid level of the molten copper.

[0038] The slag stopper brick 4 is suspended, and the copper slag on the upper layer (liquid surface) of the copper liquid is blocked. The copper liquid flows through the lower part of the slag stopper brick 4 to separate the copper slag.

[0039] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
