Description

Technical Field

[0001] The utility model relates to the technical field of phosphorus furnace production equipment, in particular to a water-cooled graphite slag outlet structure of a phosphorus furnace. Background Art

[0002] In the smelting production process of yellow phosphate ore, the phosphorus furnace is a key equipment. Its operating efficiency and stability directly affect the output and quality of the product. The slag outlet of the phosphorus furnace is the only channel for slag discharge. It is exposed to the dual effects of thermal stress and mechanical stress for a long time, resulting in material ablation, wear and even damage. This not only shortens the service life of the equipment, but also increases maintenance costs and downtime, seriously affecting production efficiency and economic benefits.

[0003] In recent years, with the continuous progress of materials science and the rapid development of industrial technology, graphite materials have gradually attracted people's attention due to their excellent high temperature resistance, corrosion resistance and thermal conductivity. Graphite materials can still maintain high strength and stability at high temperatures, and have good self-lubrication properties, which can effectively reduce mechanical wear.

[0004] Currently, to address the issue of traditional slag tapping areas being susceptible to damage, graphite is often used as the slag tapping structure for phosphorus furnaces. However, simply using graphite as the tapping port also presents certain issues. Although graphite is heat-resistant, its surface temperature remains high without cooling measures, easily causing the surrounding environment to heat up, affecting the normal operation of other equipment and reducing the service life of the graphite tapping port structure itself. In light of this, we propose a water-cooled graphite tapping port structure for phosphorus furnaces. Utility Model Content

[0005] The purpose of the utility model is to provide a water-cooled graphite slag outlet structure for a phosphorus furnace to solve the defects mentioned in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] Preferably, an adding pipe is fixedly installed on the top of the chiller, and the adding pipe is connected to the water tank in the chiller.

[0013] Preferably, a top cover is hingedly connected to the top surface of the adding tube via a hinge, and a handle is fixedly mounted on the side surface of the top cover.

[0014] Preferably, the top end of the graphite hollow cone passes through the top plate of the upper water storage cylinder, and the bottom end of the graphite hollow cone passes through the bottom plate of the lower water storage cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model provides a graphite hollow cone, which can effectively reduce mechanical wear because the graphite material can still maintain high strength and stability at high temperatures. In addition, an upper water storage cylinder and a lower water storage cylinder are provided on the outside of the graphite hollow cone, and cold water can be transported into the upper water storage cylinder and the lower water storage cylinder for cooling operation, thereby cooling the graphite hollow cone, which is beneficial to extending the service life of the graphite hollow cone and achieving the effect of water-cooling the graphite slag outlet.

[0017] 2. The utility model provides an upper water storage chamber and a lower water storage chamber that are connected by a conducting pipe. Since the top of the graphite hollow cone is closer to the slag outlet, the temperature of the slag outlet is relatively higher. At this time, the top of the graphite hollow cone is cooled in advance and then the bottom is cooled, which can improve the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
