Description

Technical Field

[0001] The utility model belongs to the technical field of casting smelting, and in particular relates to a furnace for smelting raw materials of fire hydrant castings. Background Art

[0002] Fire hydrants are formally called fire hydrants. They are fixed fire-fighting facilities. Their main functions are to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. A smelting furnace is a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloys through operations such as slagging and refining. A smelting furnace is an indispensable casting production and processing equipment.

[0003] After searching, the Chinese utility model patent application document with Chinese patent authorization announcement number CN211823802U discloses a metal casting raw material smelting device, including a bottom plate. The operator first moves the smelting device to a specified position through a universal wheel, and the motor opens the furnace cover through a screw, and the metal casting raw material to be smelted is placed in the interior of the smelting chamber. Then the motor drives the slider through the screw, and the slider drives the furnace cover to close on the top of the smelting furnace. The pressure rod is flipped so that the protrusion is inserted into the interior of the slot, and the pin is inserted into the interior of the positioning hole through the action of the spring, which can effectively position the pressure rod. At the same time, the pressure groove is clamped on the top of the furnace cover to fix the furnace cover for a second time, thereby improving the sealing between the smelting furnace and the furnace cover. When the electric heating pipe heats the interior of the smelting chamber, the electric heating pipe is distributed in a spiral structure so that the interior of the smelting chamber can be fully smelted.

[0004] In view of the above-mentioned related technologies, the smelting furnace is provided with a hand wheel, a rotating shaft, a smelting furnace, and a smelting chamber. When the smelting is completed, the smelting furnace can be turned over by driving the rotating shaft through the hand wheel to discharge the molten liquid. When the hand wheel is held, the temperature of the smelting furnace is too high and the molten liquid cannot be discharged safely and effectively. Therefore, it is urgent to design a fire hydrant casting raw material smelting furnace to deal with these problems. Utility Model Content
