Embodiment 1

[0034] refer to Figure 1~3 : A vacuum continuous feeding device, comprising a feed port 6, a vacuum sealed box 2, a barrel 3 and a lifting device 4, the feed port 6 is arranged on a smelting furnace, and a control valve 1 is sealed on the feed port 6 ; The vacuum-sealed box 2 is provided with an accommodation space, and the lower end of the accommodation space is provided with an opening corresponding to the feeding port 6; the barrel 3 is arranged in the accommodation space of the vacuum-sealed box 2, and the barrel 3 The lower side is also provided with a discharge device 31; the lifting device 4 is sealed and arranged on the upper part of the accommodating space of the vacuum sealed box 2, and drives the barrel 3 and the discharge device 31 to move up and down.

[0035] In the above scheme, the vacuum sealing box 2 is installed on the feeding port 6 above the smelting furnace, and after the storage space in the vacuum sealing box 2 is evacuated into a vacuum state by the v...

Embodiment 2

[0049] Refer to attached Figure 4 : The difference between this embodiment and embodiment 1 is:

[0050] The opening at the lower end of the barrel 3 is circular, and the discharge bottom plate 311 is a four-piece structure that equally divides the shape of the opening at the lower end. The circular lower opening has the characteristics of simple processing and high adaptability; and setting the unloading bottom plate 311 as an equally divided petal-shaped structure can reduce the difficulty of installation and processing, and ensure that the unloading bottom plate 311 is open to the lower end of the barrel 3 of tightness.

Embodiment 3

[0052] Refer to attached Figure 5~6 : The difference between this embodiment and embodiment 2 is:

[0053] A sealing member 313 or a sealing structure 314 is provided on the side of the discharge bottom plate 311 .

[0054] It should be pointed out that, according to specific sealing requirements, the sealing member 313 is a sealing piece, a sealing ring or a sealing ring embedded or fixed on the side of the discharge bottom plate 311, and the material of the sealing ring is preferably high-temperature-resistant rubber or graphite ring; The sealing structure 314 is respectively provided with a sealing protrusion on the side of the discharge bottom plate 311 and a corresponding sealing groove on the side of the adjacent discharge bottom plate 311 . By providing the sealing member 313 or the sealing structure 314 , it is possible to better prevent the material from leaking out of the discharge bottom plate 311 .

Abstract

The invention discloses a vacuum continuous feeding device. The vacuum continuous feeding device comprises a feeding opening, a vacuum sealing box, a charging barrel and a lifting device. The feedingopening is arranged on a smelting furnace, and a control valve is arranged on the feeding opening in a sealing mode. An accommodating space is formed in the vacuum sealing box, and an opening corresponding to the feeding opening is formed in the lower end of the accommodating space. The charging barrel is arranged in the accommodating space of the vacuum sealing box, and a discharging device is further arranged on the lower side of the charging barrel. The lifting device is arranged on the upper part of the accommodating space of the vacuum sealing box in a sealing mode, and drives the charging barrel and the discharging device to move up and down. The vacuum continuous feeding device has the characteristics of being simple in structure, convenient to operate, and high in stability, fast feeding under the premise of not destroying vacuum environment of the smelting furnace can be realized, and secondary feeding can be carried out without an additional charging barrel being arranged.

Description

technical field [0001] The invention belongs to the field of vacuum smelting, in particular to a vacuum continuous feeding device. Background technique [0002] Smelting and casting technology in a vacuum environment is an important method to produce high-quality metal alloy materials and mechanical parts. The production method of this technology can ensure the stable composition of smelted metals, less impurities, high purity, and low oxygen content. The production process is energy-saving and environmentally friendly. The advantages. However, after the traditional vacuum smelting completes the first smelting, it usually needs to destroy the vacuum environment in the smelting furnace for secondary feeding. This feeding method has low production efficiency and high consumption cost. [0003] CN206279282U discloses a device for continuously feeding and accelerating silicon material in a straight-pull single crystal furnace. It includes a vertical cylindrical material barrel...
