A more environmentally friendly and durable toaster

Generally speaking, steel ladles need to be baked after construction and before being filled with molten steel. The equipment used to bake steel ladles is called a ladle baking machine. Baking is one of the main steps in the casting process, and the performance of the ladle has a significant impact on the steelmaking temperature, steelmaking efficiency, and furnace age of the converter. There is a type of ladle warmer on the market, which has the disadvantage that the flame generated by oxygen coming into contact with oil and gas at the burner will spread out and cannot gather, resulting in a lower flame temperature at the center of the burner and poor heating effect on the ladle, consuming a large amount of fuel and not conducive to energy conservation. In order to further reduce energy consumption, it is necessary to renovate the above-mentioned baking machine.

To solve the problems of the inability of existing toasters to gather flames on the burner and low heating efficiency, technicians have provided a toaster. In order to achieve the above objectives, it is achieved through the following technical solution: a toaster comprising a bracket and multiple burners, wherein the bracket is provided with a first connecting pipe for ventilation and a second connecting pipe for oil, and the burner comprises an oil inlet nozzle and an air inlet nozzle spaced on the oil inlet nozzle, each air inlet nozzle is connected to the first connecting pipe through a corresponding air inlet pipe, and each oil inlet nozzle is connected to the second connecting pipe through a corresponding oil inlet pipe. The outer surface of each burner is connected with a combustion supporting component, which includes a conical cylinder set coaxially with the intake nozzle, and the direction of the cone tip of the conical cylinder is consistent with the injection direction of the burner; The outer surface of the intake nozzle is equipped with external threads; The bottom end of the conical cylinder is equipped with an annular skeleton; The inner surface of the annular skeleton is equipped with internal threads that match the external threads. During operation, gas enters through the first connecting pipe and is then discharged from the corresponding inlet nozzles through the inlet pipes. Oil enters through the second connecting pipe and is then discharged from the corresponding inlet nozzles through the inlet pipes. Gas and oil mix and come into contact at the conical cylinder to form a flame, while external air enters the conical cylinder through the annular skeleton at the bottom, forming a guiding effect and a surrounding ring, causing the flame to gather towards the center point and spray out through the cone tip of the conical cylinder. At the same time, the conical cylinder and the annular skeleton are screw connected. The oil inlet outside the conical cylinder is equipped with an impeller, and the central axis of the impeller passes through the side walls of the oil inlet and the air inlet. The central axis outside the air inlet is fitted with a bevel gear, and the outer wall of the air inlet on the bevel gear side is hinged with a gear shaft. A circular fan is rotatably fitted on the outer surface of the air inlet between the lower end of the gear shaft and the external thread. The impeller and the annular fan are installed together, and the impeller rotates by the oil flow, which drives the central shaft to rotate. The bevel gear meshes with the bevel gear to rotate the gear shaft. The gear shaft meshes with the gear ring at the upper end of the annular fan hub, causing the annular fan to rotate and the air circulation inside the conical cylinder to be faster, resulting in more complete flame combustion.

Compared with existing technology, the beneficial effect of this ladle roaster is that, due to the setting of combustion supporting components, the flame gathering effect of the nozzle spraying position is better when heating the ladle throughout the ladle roaster; At the same time, the external threads on the outer surface of the intake port are matched with the internal threads of the annular skeleton, which can adjust the distance between the cone tip and the nozzle position, change the degree of flame concentration, improve energy utilization efficiency, and promote environmental protection with strong practicality.
