Electro-magnetic induction discharge valve of small smelting furnace

Abstract

An electro-magnetic induction discharge valve of a small smelting furnace consists of a medium-frequency power supply, a control box, an inductance coil, a medium-frequency magnetic core, a packing material, a cooling water jacket, water pipe connectors, a smelting furnace cover, a smelting furnace body, a heat preserving furnace body and a heat preserving furnace cover. The medium-frequency magnetic core is U-shaped, two ends of the medium-frequency magnetic core are provided with through holes for installing a discharge pipe, and gaps required by the packing material and thermal expansion deformation are arranged on the matching faces of the through holes and the discharge pipe. The inductance coil is arranged in the middle of the medium-frequency magnetic core, and the wire end is connected with the medium-frequency power supply and the control box. The smelting furnace is only limited to metal furnace charges meeting the using temperature of a discharge pipe material, the cooling water jacket is a C-shaped interlayer round sleeve shaped thin-wall part, a lower water pipe connector is connected with a water inlet pipe, and an upper water pipe connector is connected with a water outlet pipe and an automatic exhaust valve. One end of the discharge pipe penetrates into the medium-frequency magnetic core and the cooling water jacket and then is reliably connected with a discharge port of the smelting furnace body, and the other end of the discharge pipe extends into a heat preserving furnace. The heat-resisting packing material is filled among the medium-frequency magnetic core, the cooling water jacket and the discharge pipe, and the smelting furnace and the heat preserving furnace are provided with the smelting furnace cover and the heat preserving furnace cover respectively.

Description

technical field [0001] The invention relates to an electromagnetic induction discharge valve for a small melting furnace. Background technique [0002] At present, the outlets of small furnaces are mostly tapered plugging structures, which are often blocked with graphite plugs lined with asbestos pads. An open aqueduct is set outside the outlet, and a long handle is installed on the plugs for manual plugging or opening of the discharge. For oral use. Pull out the plug, and the molten metal in the furnace is discharged from the outlet through the aqueduct into the holding furnace. With this traditional operation method, personnel have to take the risk of being scalded by the splash of the melt. When the temperature is high and accompanied by a large amount of harmful volatile Working in harsh environments is a test for personal safety and health. Contents of the invention [0003] The invention provides a small melting furnace electromagnetic induction discharge valve, wh...
