Description

Technical Field

[0001] The utility model relates to the technical field of smelting devices, in particular to a smelting device and tantalum plate production equipment. Background Technique

[0002] Tantalum-niobium ore of the smelting device is the main raw material for producing tantalum. However, there are often various metals in tantalum-niobium ore. Therefore, the main steps of tantalum smelting are to decompose the concentrate, purify and separate tantalum and niobium to produce pure compounds of tantalum and niobium, and finally produce metals. Ore decomposition can adopt methods such as hydrofluoric acid decomposition method, sodium hydroxide melting method and chlorination method. Tantalum-niobium separation can adopt solvent extraction method (common extractants are methyl isobutyl ketone (MIBK), tributyl phosphate (TBP), sec-octanol and acetamide, etc.), fractional crystallization method and ion exchange method.

[0003] When the existing smelting device smelts the raw materials for tantalum plate production, the content of wolframite is too high, resulting in too high a defective rate of the raw materials for tantalum plate production. It is difficult to achieve the separation of tantalum-niobium iron ore and wolframite by one-time filtration, reducing the tantalum-niobium iron content and affecting the quality of tantalum plate production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a smelting device and tantalum plate production equipment to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution. The smelting device and tantalum plate production equipment: include a smelting and screening box and an internal separation mechanism.

The internal separation mechanism is installed inside the stirring cylinder. One side of the stirring cylinder is connected and communicated with a feeding cylinder, and a servo motor is installed at the top of the stirring cylinder. The bottom end of the smelting and screening box is fixedly connected with a discharging cylinder, and a motor screw rod is installed inside the discharging cylinder.

[0006] Preferably, the smelting and screening box is movably connected with the internal screening mechanism, and the internal screening mechanism is communicated with the stirring cylinder.

[0009] Preferably, the stirring cylinder is driven by a servo motor to rotate and convey raw materials into the filter cylinder.

[0010] Preferably, the built-in separation mechanism includes a main shaft, a feeding and screening cylinder, a rotating disk, and a stirring shaft. The bottom end of the main shaft penetrates through the feeding and screening cylinder.

[0013] 1. In the present utility model, through the arranged built-in gear and main shaft, the main shaft on the servo motor is movably installed in the middle of the built-in gear. Relying on the power of the servo motor, the built-in gear and the main shaft can be driven to rotate and stir.

Start the servo motor 6 on the stirring cylinder 3 and the internal separation mechanism 4, which can drive the components of the internal separation mechanism 4 inside the stirring cylinder 3 to perform rotational motion. Then send the separated raw materials into the internal screening mechanism 2, and through the motor screw rod 8 in the discharging cylinder 7, melt and discharge the tantalum plate production raw materials. The melting and screening box 1 is movably connected with the internal screening mechanism 2, and the internal screening mechanism 2 is communicated with the stirring cylinder 3. The components of the internal screening mechanism 2 are movably installed at the top of the melting and screening box 1.

[0023] Embodiment 2

[0024] As Figure 2 and Figure 3As shown, the built-in screening mechanism 2 includes a built-in gear 9 and a filter cylinder 10. The built-in gear 9 is installed inside the filter cylinder 10. The mixing cylinder 3 is driven by a servo motor 6 to rotate and convey raw materials into the filter cylinder 10. The filter cylinder 10 is movably installed at the connection between the mixing cylinder 3 and the melting and screening box 1, so that the built-in gear 9 is movably installed inside the filter cylinder 10. After the tantalum plate production raw materials are added into the feeding cylinder 5, when the tantalum plate production raw materials are separated from tantalite and wolframite through the mixing cylinder 3 and then enter the filter cylinder 10, the built-in gear 9 inside the filter cylinder 10 can, under the drive of the servo motor 6, perform secondary stirring on the raw materials screened by the filter cylinder 10, the mixing cylinder 3 and the melting and screening box 1, and then pass through the rotary screening and filtering of the filter cylinder 10, which is conducive to the multiple separation of tantalite and wolframite. When the melting device melts the tantalum plate production raw materials, the content of wolframite is reduced, and the defective rate of the melted tantalum plate production raw materials is reduced. Multiple rotary separation and filtration can be carried out to separate tantalite and wolframite, and the tantalum-niobium iron content is increased. The built-in separation mechanism 4 includes a main shaft 11, a feeding and screening cylinder 12, a rotary disk 13 and a stirring shaft 14. The bottom end of the main shaft 11 penetrates through the feeding and screening cylinder 12. The bottom end of the feeding and screening cylinder 12 is provided with a rotary disk 13. Stirring shafts 14 are fixedly installed around the rotary disk 13. The feeding and screening cylinder 12 is movably installed inside the mixing cylinder 3. The feeding and screening cylinder 12 can screen the tantalum plate production raw materials into the filter cylinder 10. The feeding and screening cylinder 12 is movably installed inside the mixing cylinder 3, so that the main shaft 11 on the servo motor 6 is movably installed in the middle of the built-in gear 9. Relying on the power of the servo motor 6, the built-in gear 9 and the main shaft 11 can be driven to rotate and stir. At the same time, under the action of the servo motor 6, the feeding and screening cylinder 12 performs a rotary separation motion. The raw materials inside the feeding and screening cylinder 12 enter the built-in gear 9 and the main shaft 11 for secondary stirring and separation. The rotary disk 13 and the stirring shafts 14 at the bottom end of the main shaft 11 are movably installed at the bottom end inside the melting and screening box 1 and perform rotary stirring relying on the power of the servo motor 6.

[0025] In actual use, start the servo motor 6 on the mixing drum 3 and the built-in separation mechanism 4, which can drive the components of the built-in separation mechanism 4 inside the mixing drum 3 to perform rotational motion. Then, the separated raw materials are sent into the built-in screening mechanism 2. The filter cylinder 10 is movably installed at the connection between the mixing drum 3 and the smelting and screening box 1, so that the built-in gear 9 is movably installed inside the filter cylinder 10. When the raw materials for tantalum plate production are added into the feeding cylinder 5, when the raw materials for tantalum plate production pass through the mixing drum 3 for the separation of tantalite and wolframite, and then enter the inside of the filter cylinder 10, the built-in gear 9 inside the filter cylinder 10 can, under the drive of the servo motor 6, perform secondary stirring on the raw materials screened by the filter cylinder 10, the mixing drum 3 and the smelting and screening box 1. Then, through the rotational screening and filtering of the filter cylinder 10, it is conducive to the multiple separation of tantalite and wolframite. The feeding and screening cylinder 12 is movably installed inside the mixing drum 3, so that the main shaft 11 on the servo motor 6 is movably installed in the middle of the built-in gear 9. Relying on the power of the servo motor 6, the built-in gear 9 and the main shaft 11 can be driven to perform rotational stirring. At the same time, under the action of the servo motor 6, the feeding and screening cylinder 12 performs rotational separation motion.
