Description

TECHNICAL FIELD

[0001] The utility model relates to zinc alloy preparation technical field especially relates to a zinc alloy metal liquid's drainage device. BACKGROUND

[0002] Zinc alloy is a commonly used non-ferrous metal. In the production process of the upstream and midstream of the zinc alloy industry chain, there is usually a step of transferring zinc alloy metal liquid from one furnace to another furnace. In this step, the traditional process usually introduces the zinc alloy metal liquid to the target furnace mouth through various ways, and then directly pours into the target furnace body in the form of a waterfall.

[0003] In the process of pouring the zinc alloy metal liquid in the form of a waterfall, due to the high temperature and easy oxidation properties of the zinc alloy liquid, the surface oxide scale of the target furnace metal liquid is destroyed by the waterfall and rolled into the liquid inside, and then slowly floats up, and new oxide scale is formed again on the surface of the target furnace metal liquid. Due to the long pouring time during the transfer of the zinc alloy metal liquid, after pouring is completed, it can be observed that there is a very obvious thick layer of zinc slag formed on the surface of the target furnace, which increases the cost of zinc slag treatment. SUMMARY

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0028] Embodiment 1

[0029] Please refer to Figs. 1-2 The present application provides a technical solution: a drainage device for zinc alloy metal liquid, comprising:

[0030] The drainage groove 1 is connected with the metal liquid conveying groove 11 at the upper end and extends to the bottom of the target furnace 12 at the lower end.

[0031] The support frame 2 comprises a cross beam 21 and a vertical rod 22. The cross beam 21 is placed above the furnace mouth of the target furnace 12, and the end of the cross beam 21 is placed on the furnace mouth platform. The vertical rod 22 is fixedly installed on the cross beam 21, and the bottom of the vertical rod 22 is connected with the drainage groove 1.

[0032] A plurality of connecting lugs 13 are arranged on the side wall of the drainage groove 1 along the length direction of the drainage groove 1, and the bottom of the vertical rod 22 is connected with the connecting lugs 13. The bottom of the vertical rod 22 is bent and passes through the through hole of the connecting lug 13, so as to realize the connection between the support frame 2 and the drainage groove 1. The multiple connecting lugs 13 realize the free connection at multiple points. The free connection at multiple points can change the height and inclination of the drainage groove, so as to make the device compatible with various working conditions and adapt to different target furnaces.

[0033] A cross brace 221 is arranged between the two vertical rods 22, which can prevent the vertical rod 22 from deforming and improve the lifting stability of the drainage groove 1.

[0034] Working principle: When pouring molten metal, the diversion trough 1 is pre-installed at the target furnace 12 via the support frame 2. After the molten metal conveying trough 11 delivers the zinc alloy molten metal to the furnace opening of the target furnace 12, the upper end of the diversion trough 1 can stably receive the zinc alloy molten metal. The zinc alloy molten metal is diverted to the bottom of the furnace through the diversion trough 1, effectively avoiding damage to the oxide scale on the surface of the molten metal inside the target furnace 12 by the zinc alloy molten metal. Compared with the traditional waterfall pouring, the amount of zinc dross on the surface of the target furnace 12 after pouring is significantly reduced, which can significantly reduce the cost of zinc dross treatment. The method is efficient, simple to operate, and stable in operation.

[0035] The reduction in zinc slag is related to the waterfall height, flow rate, temperature, and composition before the installation of this device in actual working conditions. Generally, the reduction can reach more than 30%, which significantly reduces production costs and waste slag treatment costs, and improves production efficiency.

[0036] After use, remove the drainage device, ensuring safety, and store it after it has cooled down.

[0037] Example 2

[0038] This embodiment further improves upon the above embodiment by providing the following technical solution: a diagonal rod 24 is provided between the vertical rod 22 and the drainage channel 1. One end of the diagonal rod 24 is connected to the vertical rod 22, and the other end is connected to the connecting lug 13. The diagonal rod provides diagonal bracing and reinforcement to the vertical rod. The cooperation between the vertical rod and the diagonal rod ensures that the drainage channel 1 and the support frame 2 are stably connected and form a whole.

[0039] The vertical and diagonal rods can be connected at different points using the connecting lugs 13, depending on the operating conditions, so that the height and slope of the flow channel allow the molten metal to flow stably from the furnace opening to the furnace bottom. The connection methods at the points include, but are not limited to, the connection methods of the vertical and diagonal rods shown in the figure, as long as the points can be stably connected and disassembled.

[0041] This embodiment further improves upon the above embodiment by providing the following technical solution: a support portion 23 is provided at the end of the crossbeam 21, and the support portion 23 has an "I"-shaped structure. The support portion 23 is an "I"-shaped structure formed by welding the rod body. The support portion 23 increases the contact area between the end of the crossbeam 21 and the furnace opening platform, so that the crossbeam 21 can be placed more stably on the furnace opening platform, making it easier to fix the crossbeam.

[0042] In addition, the width and structure of both ends of the crossbeam can be adjusted appropriately according to the site conditions to ensure that the entire device is placed stably.
