Embodiment 1

[0044] refer to figure 1 : a kind of double tundish device for metal atomization pulverizing equipment of the present embodiment, comprises 2 tundishes 16, mobile trolley, translation cylinder and lift motor; Described tundish 16 is placed on the mobile trolley; Described mobile trolley Including the first mobile trolley 13 and the second mobile trolley 24, the mobile trolley is driven by a translation cylinder to drive the tundish 16 to move left and right along the flat steel sliding track 17; the translation cylinder includes a left translation cylinder installed on both sides of the tundish 16 9 and the right translation cylinder 21, the piston rod 10 of the translation cylinder is a hollow pipe body, and the hollow pipe body has a built-in spray plate gas pipe connected to the tundish 16; it can reduce the impact of high temperature splashes in the smelting chamber of the metal atomization powder making equipment. The damage of the trachea, and then improve the use safety...

Embodiment 2

[0053] refer to Figure 2~5 : compared with embodiment 1, a kind of metal atomization pulverization equipment of the present embodiment uses double tundish device, there is following difference:

[0054] A connecting plate 15 is arranged between the first moving trolley 13 and the second moving trolley 24, and an isolating plug 14 is arranged below the connecting plate 15 for isolating the smelting chamber and the atomizing chamber in the metal atomization powder making equipment. By setting the connection plate 15 at the connection of the mobile trolley and the isolation plug 14 under the connection plate 15, the tundish 16 can be transformed into three stations during use, that is, the tundish working position, the spare tundish replacement position and the isolation Compared with the double-station tundish changing device (tundish working position and spare tundish replacement position) in the prior art, the suspending work position is added with an isolated suspending work...

Abstract

The invention discloses a double-tundish device for metal atomization pulverizing equipment. The device comprises two tundishes, a mobile car, a translation cylinder and a lifting motor; the tundishes are put on the mobile car; the mobile car comprises a first mobile car and a second mobile car; the mobile car is driven through the translation cylinder to drive the tundishes to move left and right along a flat steel slide rail; the translation cylinder comprises a left translation cylinder and a right translation cylinder mounted on two sides of the tundishes; piston rods of the cylinders are hollow pipe bodies; spraying disc air pipes connected with the tundishes are positioned in the hollow pipe bodies; and the lifting motor comprises a left lifting motor and a right lifting motor for respectively driving the first mobile car and the second mobile car to lift up and down. The double-tundish device for the metal atomization pulverizing equipment is simple in structure, long in service life and convenient to replace different tundishes, and reduces damage to the spraying disc air pipes by high-temperature splashing matters in a smelting furnace; and the smelting furnace is effectively isolated from an atomization device through an isolation plug, so that the metal atomization pulverizing efficiency is high.

Description

technical field [0001] The invention relates to an atomized powder-making equipment, in particular to a double tundish device for metal atomized powder-making equipment under vacuum smelting and the atomized powder-making equipment composed of the same. Background technique [0002] The metal atomization device is generally composed of several parts such as a melting furnace, a tundish, an atomization chamber, an atomization nozzle, a powder collector, and a cyclone separator. A tundish is used to raise the temperature of the molten metal to a predetermined superheat above the melting point. However, the tundish in the existing metal atomization pulverization device is single. When the tundish is blocked or other faults, production needs to be stopped for maintenance, which leads to low equipment utilization and low production efficiency of the metal atomization pulverization device. [0003] CN 103894617 A discloses a metal powder atomization device, which includes an uppe...
