[0001] This utility model relates to the field of antimony smelting technology, and in particular to a waste slag transfer device. Background Technology
[0002] Slag generated during smelting is solid waste produced in the metallurgical industry. In the production of crude antimony through antimony smelting, a large amount of slag (i.e., waste slag) is produced. This slag has high recycling value and needs to be transferred and recycled. However, in the current transfer and recycling process, when the waste slag is transferred to the slag-receiving hopper, it is prone to splashing because it is generally in a solid-liquid mixed state at this stage.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] Please refer to Figures 1-3 A waste transfer device includes a transfer support 1, a transfer groove 2 rotatably mounted on the transfer support 1, a plurality of waste collection hoppers 3 movably mounted in the transfer groove 2, and a smoke extraction device at the top of the transfer groove 2.
[0022] A feeding device is provided on the left side of the transfer tank 2. The feeding device includes a feeding bracket 4, which is fixed to the side of the transfer bracket 1. A feeding pipe 5 is provided vertically downward on the feeding bracket 4. The discharge end of the feeding pipe 5 extends downward to the top of the slag receiving hopper 3. A pair of connecting pipes 6 are fitted at the bottom of the feeding pipe 5. A shielding funnel 7 is provided at the bottom of the connecting pipes 6. An adjusting cylinder 8 is also provided vertically downward on the top of the feeding bracket 4. A connecting plate 9 is fixed on the piston rod of the adjusting cylinder 8. One end of the connecting plate 9 is fixed to the connecting pipe 6.
[0023] In this embodiment, when the slag-receiving hopper 3 moves to the bottom of the discharge pipe 5, the regulating cylinder 8 is activated. Under the action of the regulating cylinder 8, the shielding funnel 7 can be placed over the slag-receiving hopper 3, thereby preventing the slag from splashing during the transfer process.
[0024] The fume extraction device includes a fume hood 10, which covers the top of the transfer tank 2. Several negative pressure fume extraction pipes 11 are installed on the top of the fume hood 10. In this embodiment, the fume hood 10 is installed on the top of the transfer tank 2. Through the several negative pressure fume extraction pipes 11 on the fume hood 10, the flue gas produced from the waste residue can be collected, preventing it from leaking into the production workshop.
[0025] A plurality of first limiting blocks 12 are provided on the inner wall of the transfer tank 2, and a plurality of second limiting blocks 13 corresponding to the first limiting blocks 12 are provided on the outer wall of the transfer tank 2. First limiting grooves 14 and second limiting grooves 15 are respectively provided on the first limiting blocks 12 and the second limiting blocks 13. A first connecting block 16 is provided on the side of the slag receiving hopper 3 near the first limiting blocks 12, and a second connecting block 17 is provided on the side of the slag receiving hopper 3 near the second limiting blocks 13.
[0026] In this embodiment, the first docking block 16 and the second docking block 17 can be inserted into the first limiting groove 14 and the second limiting groove 15 respectively, thereby stably limiting the slag receiving hopper 3 inside the transfer groove 2 and improving the transfer stability.
[0027] A transmission rack 18 is provided on the inner outer wall of the transfer groove 2, and a transmission bracket 20 is fixed on the inner outer wall of the transfer bracket 1. A transmission motor 21 is vertically downward on the transmission bracket 20, and a transmission gear 19 is fixed on the rotor of the transmission motor 21. The transmission gear 19 meshes with the transmission rack 18.
[0028] In this embodiment, the moving gear meshes with the transmission rack 18, and the transmission motor 21 drives the transmission gear 19 to rotate, which allows the transfer groove 2 to rotate on the transfer bracket 1.
[0029] Working principle: Several slag-collecting hoppers 3 are placed in the transfer trough 2. The drive motor 21 is started to drive the transfer trough 2 to rotate. When the slag-collecting hoppers 3 rotate to the bottom of the feed pipe 5, the regulating cylinder 8 is started. Under the action of the regulating cylinder 8, the shielding funnel 7 can be placed on top of the slag-collecting hoppers 3, and a certain amount of waste slag (i.e., the slag produced when producing crude antimony in antimony smelting) is sent into the slag-collecting hoppers 3. The above action is repeated until the slag-collecting hoppers 3 on the transfer trough 2 are full of waste slag. During the waste slag transfer process, the negative pressure flue gas pipe 11 can collect the flue gas produced by the waste slag to prevent leakage.
[0030] When all the slag hoppers 3 are full of material and moved back to their initial positions, the slag hoppers 3 are transferred to the designated positions by a crane.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
