Description

Technical Field

[0001] The utility model relates to the technical field of industrial production, in particular to a high-temperature melting furnace mouth protection device. Background Art

[0002] A melting furnace mostly refers to equipment for melting metals. The melting furnace can be divided into direct heating type and electric heating type according to the heating medium. The direct heating type is a method of heating the melting furnace with high temperature fire to melt the metal, and the electric heating type is a method of heating the melting furnace with electrical heating to melt the metal.

[0003] Announcement No. CN 220304253 U discloses an automatic opening and closing cover of a dissolving chamber of a dissolving furnace. By setting a sealing component, when the cover body covers the top of the dissolving furnace opening, the plug fixed at the bottom of the cover body will be stuck in the slot opened at the top of the dissolving furnace opening. After the cover body covers the dissolving furnace opening and closes the cover, the plug inserted in the oil filling hole is pulled out, and oil is filled into the slot through the oil filling hole to make the oil submerge the plug inserted in the slot to form an oil seal, and then the plug is inserted into the oil filling hole. By performing oil sealing treatment on the connection between the cover body and the dissolving furnace opening, a better sealing effect can be achieved to prevent the high-temperature gas, liquid or other dangerous substances inside the dissolving furnace or the dissolving chamber from leaking out, thereby easily endangering the safety and health of the operator. However, the patent still has the following problems in actual use:

[0004] Although the automatic opening and closing cover of the dissolving chamber of the dissolving furnace seals the dissolving chamber of the dissolving furnace by providing a cover body, thereby preventing the high-temperature gas, liquid or other dangerous substances inside the dissolving furnace or the dissolving chamber from leaking out, thereby endangering the safety and health of the operator, there is no relevant cooling structure at the furnace mouth of the dissolving furnace to cool the furnace mouth position. When raw materials need to be added, the furnace mouth needs to be opened and the raw materials are transported to the furnace mouth by a feeding trolley. However, due to the high temperature of the furnace mouth, the feeding trolley will be baked, causing damage to the internal parts of the trolley, thereby affecting the service life of the trolley, and it is not convenient to add materials to the dissolving furnace.

[0005] A high-temperature melting furnace mouth protection device is proposed to solve the above-mentioned problems. Utility Model Content
