Embodiment 1

[0053] The tin concentrate recyclable smelting system of the present embodiment, such as figure 1 As shown, it includes a smelting electric furnace 1, a synchronous replacement device 2 for electrode rods on the top of the smelting electric furnace 1, and a tin liquid processing device 3 after the smelting electric furnace 1 is smelted and discharged, wherein: as figure 1 and 8 As shown, the tin liquid treatment device 3 includes a sedimentation tank 32 and a static forming tank 33, the sedimentation tank 32 is arranged at the bottom of the discharge port 11 of the smelting electric furnace 1, and the upper part of the sedimentation tank 32 is opened with an overflow port 321 and a static forming tank 33 are connected; the tin slag on the upper layer of the sedimentation tank 32 flows into the standing forming tank 33 through its overflow port 321, and the refined tin liquid on the lower layer is transported to the next process through its bottom outlet; figure 2 As shown, t...

Embodiment 2

[0062] The tin concentrate recyclable smelting system of this embodiment has the same basic structure as that of Embodiment 1, the difference and improvement is that: the forming blind hole 331 is in the shape of a cone or a cone, and the molded tin slag ingot is in the shape of a corresponding cone Or cone-shaped, the forming blind hole is similar to the mold, which is convenient for mold removal, and the handle bar 341 is preset inside, which is convenient to lift out of the forming blind hole after forming; Figure 4 As shown, the vertical fixed frame 21 includes a vertical support column 212 and a support guide column 213 inside the support column 212, and also includes a boom 211 that is fixedly connected to the top of the support column 212 and the support guide column 213 in a horizontal direction; the support column 212 and the supporting guide column 213 are fixedly connected to the support platform 25; one end of the lifting arm 22 is fixedly connected with a guide fr...

Embodiment 3

[0064] A kind of tin concentrate recyclable smelting system of the present embodiment, the basic structure is the same as embodiment 2, the differences and improvements are as follows: Figure 6 As shown, the pulley mechanism 24 also includes the fifth fixed pulley 245 near the second through hole 2112 and the second movable pulley 247 on the upper surface of the lifting arm 22 parallel to the first movable pulley 246, the fifth fixed pulley 245 and the third fixed pulley 243 are arranged in the second through hole 2112 the two sides of the traction rope 231; the free end of the traction rope 231 walks around fixed pulley one 241, fixed pulley four 244, passes through hole two 2112 downwards, then walks around movable pulley one 246, passes through hole two 2112 upwards, and then winds Pass fixed pulley five 245, pass through hole two 2112 downwards, walk around movable pulley two 247, pass through hole two 2112 upwards, bypass fixed pulley three 243, fixed pulley two 242, pass...

Abstract

The invention discloses a tin concentrate recyclable smelting system and a processing technology thereof, and belongs to the technical field of tin concentrate processing. The device comprises a smelting electric furnace, an electrode bar synchronous replacement device at the top of the smelting electric furnace and a tin liquid treatment device after smelting and discharging of the smelting electric furnace, the tin liquid treatment device comprises a sedimentation tank and a standing forming tank, the sedimentation tank is arranged at the bottom of a discharging port of the smelting electric furnace, and an overflow port is formed in the upper portion of the sedimentation tank and connected with the standing forming tank; the synchronous electrode bar replacing device comprises a supporting platform, a tin concentrate transferring mechanism and an electrode bar lifting mechanism, the tin concentrate transferring mechanism and the electrode bar lifting mechanism are fixed to the supporting platform, and after a furnace body of the smelting electric furnace penetrates through the supporting platform, the furnace top of the smelting electric furnace protrudes out of the supporting platform. The electrode bar lifting mechanisms are symmetrically and vertically arranged around the furnace top; electrode bar insertion openings which are symmetrically distributed are further formed in the furnace top around the opening in the middle of the furnace top, materials fall between the electrode bars in a relatively balanced mode when fed through the opening in the middle, and then the technical effect that the materials are heated in a balanced mode is achieved.

Description

technical field [0001] The invention relates to the technical field of tin concentrate processing, in particular to a recyclable tin concentrate smelting system and a processing technology thereof. Background technique [0002] In electric smelting furnaces for the production of tin, ferroalloys, silicon, pig iron, etc., the consumable electrode rods, generally carbon electrodes, which are immersed in the charge during the working process of the electric smelting furnace are used. The electrodes are held by electrode holders. The working current is passed to the electrode clip and then to the electrode. The electrode is adjusted vertically up and down by a hydraulic cylinder to maintain a preset electrode current, or a preset resistance value. The electrode holder system described above also includes means for sliding the electrode through the electrode holder to compensate for wear of the electrode. The electrode rod used in the tin concentrate electric furnace is locate...
