Problems solved by technology

[0002] Metal melting and casting is the basic industry for industrial development, but its dust pollution is also extremely serious. Metal melting and casting enterprises will generate a lot of smoke and dust during the melting and casting process. In addition, the melting temperature is high, and the metal itself will burn and volatilize at high temperature. The atmospheric environment causes serious pollution and is a great waste of resources
[0003] At present, most manufacturers of battery zinc cakes use semi-closed reverberatory furnaces, which use diesel fuel as fuel to melt zinc. The reverberatory furnace adopts a semi-closed structure, which wastes heat. According to statistics, it takes With 32 kg of diesel oil, the energy consumption is quite large
In addition, the reverberatory furnace also has the following disadvantages: (1) It is difficult to control the temperature of the molten zinc in the furnace, and the temperature in the furnace is not uniform; (2) The metal is easy to burn, burn, oxidize, low yield, and large metal loss, which is easy to cause Environmental pollution; (3) no insulation, high energy consumption; (4) labor intensity of workers

Embodiment 1

[0034] In this embodiment, a power frequency cored induction integral cast zinc melting furnace, such as figure 1 As shown, including the furnace body 1 and the induction body 2, there are a plurality of induction bodies evenly distributed around the furnace body. The furnace wall of the furnace body is provided with a zinc ring mouth 3, and is connected with the induction body through the zinc ring mouth. The axial section is trumpet-shaped, and the diameter of the zinc ring opening at the end of the inner wall of the furnace is greater than that at the end of the outer wall of the furnace.

[0035] Such as figure 2 As shown, the furnace body includes a furnace cover 4, a furnace wall 5 and a partition wall 6. The inside of the furnace wall is a furnace, the furnace cover is arranged above the furnace hearth, and the partition wall is arranged in the furnace wall, and the space inside the furnace wall is divided into a melting zone 7 and the casting area 8, the bottom of th...

Embodiment 2

[0048] In this embodiment, a power frequency cored induction integral casting zinc melting furnace is compared with Embodiment 1, and the difference is that: as Image 6 As shown, the melt flow channel is a variable cross-section melting channel opened on the support body; with the center line at both ends of the melt flow channel as the dividing line, on the entrance side of the melt flow channel, the cross-sectional width of the melt flow channel is along the length of the melt channel. The flow direction gradually narrows, and on the outlet side of the melt flow channel, the cross-sectional width of the melt flow channel gradually expands along the flow direction of the melt. The arrow in the figure indicates the flow direction of the zinc material in the melt flow channel.

Embodiment 3

[0050] In this embodiment, a power frequency cored induction integral casting zinc melting furnace is compared with Embodiment 1, and the difference is that: as figure 2 As shown, the connection between the bottom of the furnace wall and the upper part of the furnace wall is also provided with a nitrogen filling port 19, and a nitrogen filling pipe 20 is provided at the nitrogen filling port. . During the smelting process of zinc material, nitrogen gas is injected into the furnace through the nitrogen-filled pipe, on the one hand, it can prevent the zinc material from being oxidized and play a protective role; Impurity removal.

Abstract

The invention discloses a power frequency core induction integral casting zinc melting furnace. The power frequency core induction integral casting zinc melting furnace comprises a furnace body and induction bodies. The multiple induction bodies are evenly distributed on the periphery of the furnace body. Zinc collar extensions are formed in the furnace wall of the furnace body. The furnace body is connected with the induction bodies through the zinc collar extensions. The axial section of the zinc collar extensions is in a horn shape. The diameter of the end, located in the inner wall of the furnace body, of each zinc collar extension is greater than that of the end, located in the outer wall of the furnace body, of the zinc collar extension. Compared with traditional semi-closed reverberatory furnaces, the power frequency core induction integral casting zinc melting furnace is high in melting efficiency and low in metal loss, the recovery rate of zinc materials is at least 2% higher than that of the traditional reverberatory furnaces, dust is hardly produced, the environment pollution is small, and cleaner production can be achieved.
