Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting and rolling production equipment, in particular to a water collecting trough for a vertical furnace burner cooling system with an air guide structure. Background Art

[0002] A vertical furnace is a continuous casting and rolling production equipment unit. A vertical furnace melting furnace is mainly used to melt metal raw materials and purify solid media to obtain the required properties. The melting process of raw materials mainly depends on the burner melting system of the melting furnace. In order to ensure its stable and long-term production under high temperature environment, a cooling system is introduced into the melting burner. See Figure 1 and Figure 2 As shown, Figure 1 The vertical furnace burner cooling water circulation system is shown. Figure 2 The figure shows the return water pipeline of the vertical furnace burner; wherein, in the prior art system, when the equipment is initially started each time, the water collection tank of the drainage main pipe does not flow smoothly, accompanied by overflow, which wastes water resources and leaks, increasing the unsafe factors on site.

[0003] According to on-site measurement and analysis, the water inflow is 60㎡ / h, and the drainage outlet uses a pipe with a diameter of DN200, which normally meets the drainage requirements. Figure 3 As shown, at the moment when the water circulation just starts, the circulating water of the 23 burners will basically all be collected in the water collection tank at the same time. The return water pipe below is an open structure and is connected to the atmosphere. A large amount of return water is collected in the pipe, which makes it impossible for the air in the pipe to be discharged instantly, forming an air blockage phenomenon, poor drainage, and overflow of the upper water collection tank.

[0004] Based on the above technical problems, technicians in this field urgently need to develop a water collecting tank for a vertical furnace burner cooling system with a gas guide structure. Utility Model Content
