[0023] Due to the existing technology, there is a problem where exhaust gas and condensed molten metal exit the equipment together during the production process, affecting the final product quality. Therefore, the device is equipped with a condensation mechanism and a waste gas recovery mechanism. Please refer to [link / reference needed]. Figures 1-5This utility model provides a technical solution: a vacuum distillation furnace for processing non-ferrous metal alloy slag, including a distillation furnace body 1, a support leg 2 fixedly installed at the bottom of the distillation furnace body 1, an end cover 5 fixedly installed at the top of the distillation furnace body 1, a motor 7 fixedly installed at the middle position of the end cover 5, a waste gas treatment device 8 fixedly installed on the side of the motor 7, a feed inlet 6 fixedly installed on the other side of the motor 7, and a vacuum pump 9 fixedly installed on the side of the feed inlet 6; the vacuum distillation furnace for processing non-ferrous metal alloy slag includes a condensation mechanism, a waste gas recovery mechanism, and a cleaning mechanism.

[0026] The centrifuge cylinder 301 is evenly provided with multiple sets of through holes 302. The upper end of the through holes 302 is in contact with the lower end of the condenser plate 204. The connection part between the condenser plate 204 and the smelting furnace 201 is provided with four sets of through grooves 307. The top of the condenser pipe 206 is fixedly installed with an exhaust pipe 303. The end of the exhaust pipe 303 is fixedly installed on the waste gas treatment device 8.

[0027] The bottom of the smelting furnace 201 is fixedly equipped with a waste outlet 3, the bottom of the distillation furnace body 1 is conical, and the bottom of the distillation furnace body 1 is fixedly equipped with a metal outlet 4. Both the waste outlet 3 and the metal outlet 4 are equipped with control valves.

[0028] The material to be processed is fed into the smelting furnace 201 through the feed port 6. The equipment is started to smelt the material in the smelting furnace 201. The condensation pump is started, and the condensed metal vapor flows into the space between the smelting furnace 201 and the centrifuge 301 through the channel 307 under the action of the condensation plate 204. The centrifuge is started to remove any waste gas that may be contained in the molten metal and to perform gas-liquid separation. Finally, the gas is discharged from the equipment through the metal outlet 4.

[0029] Example 2:

[0030] Based on Example 1, during the condensation of metal vapor, some substances remain on the condenser plate. These residues gradually accumulate on the surface of the condenser plate, forming an insulating layer that hinders heat exchange between the subsequent metal vapor and the condenser plate, reducing condensation efficiency. This results in more metal vapor not condensing in time and potentially being drawn away with the airflow, causing a decrease in metal recovery rate. Therefore, this device is equipped with a cleaning mechanism (see [link]). Figures 3-5 This utility model provides a technical solution: a vacuum distillation furnace for processing non-ferrous metal alloy slag, the cleaning mechanism including a motor 7, the output shaft of the motor 7 is fixedly installed on a drive shaft 401, the drive shaft 401 passes through a smelting furnace 201 and is fixedly installed in the middle of a centrifuge cylinder 301, a sleeve shaft 402 is movably installed on the drive shaft 401, and three sets of scrapers 409 are fixedly installed on the sleeve shaft 402, the scrapers 409 are in contact with the inner wall of the smelting furnace 201 and the condenser plate 204.

The transmission ratio between the second gear 405 and the third gear 406 is 1:6, and the transmission ratio between the fourth gear 408 and the first gear 404 is 6:1.

[0032] The starting motor 7 drives the centrifuge cylinder 301 and the scraper 409 to rotate through gear transmission. Since the transmission ratio of each gear is different, the centrifuge cylinder 301 needs to rotate at a high speed, while the scraper 409 needs to rotate at a lower speed. Under the action of the scraper 409, the condenser plate 20 is cleaned, which further improves the condensation efficiency. At the same time, the scraper 409 plays a role in stirring the material in the smelting furnace 201. The slag after smelting is discharged from the smelting furnace 201 through the waste outlet 3.
