It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: Refer to Figures 1-3 As shown: A sulfur-iron separation device includes a flotation machine 1. A scraper 6 is rotatably connected to one side of the flotation machine 1. A guide plate 5 is provided at the bottom of the scraper 6. A cleaning mechanism is provided on one side of the guide plate 5. The cleaning mechanism includes a vibrating motor 3, a flushing pipe 7, and a connecting pipe 17. A collection box 4 is bolted to one side of the vibrating motor 3. The collection box 4 is bolted to the flotation machine 1. The inner wall of the collection box 4 is fixedly connected to the flushing pipe 7. One side of the flushing pipe 7 is fixedly connected to the connecting pipe 17. The bottom of the connecting pipe 17 is fixedly connected to... The flow meter 16 has a fixed connection at its bottom to the outlet of the water pump 12, and the water pump 12 has a fixed connection at its bottom to the water tank 13. The inlet of the water pump 12 is connected to the water tank 13. The collection tank 4 has a fixed connection on one side to the discharge pipe 2. The inner wall of the collection tank 4 is slidably connected to the auxiliary frame 10. The inner wall of the auxiliary frame 10 is fixedly connected to the auxiliary strip 9. The top of the auxiliary frame 10 is connected to the hydraulic push rod 8 by bolts. The outer ring of the hydraulic push rod 8 is fixedly connected to the inner wall of the collection tank 4. The bottom of the inner cavity of the collection tank 4 is provided with an inclined plane.

[0020] The scraper 6 rotates in conjunction with the flotation machine 1, rotating synchronously during the operation of the flotation machine 1. It scrapes the foam generated during the separation of sulfur and iron away from the interior of the flotation machine 1 and guides it to the guide plate 5 at the bottom. The bottom of the collection box 4 has an inclined plane, its core function being to receive the foam and provide temporary storage space; it also serves as a mounting carrier for components such as the vibrating motor 3 and the flushing pipe 7. The auxiliary strip 9 is fixed to the inner wall of the auxiliary frame 10. The top of the auxiliary frame 10 is connected to the hydraulic push rod 8 by bolts and slides against the inner wall of the collection box 4. The outer ring of the hydraulic push rod 8 is fixed to the inner wall of the collection box 4. During operation, the hydraulic push rod 8 drives the auxiliary frame 10, causing the auxiliary strip 9 to move up and down, pressing down and compacting the foam in the collection box 4. The discharge pipe 2 is fixedly connected to one side of the collection box 4, with an external extraction device at the end. Under the downward pressure of the auxiliary frame 10, the compacted foam is quickly extracted and collected. The vibrating motor 3 is connected to the collection box 4 by bolts. When started, it generates vibration and transmits it to the collection box 4, causing residual foam and fine pyrite particles on the inner wall of the collection box 4 and the surfaces of the auxiliary frame 10 and auxiliary strips 9 to fall off. The flushing pipe 7 is fixed to the inner wall of the collection box 4 and has nozzles with different directions at the bottom. It is connected to the outlet of the water pump 12 through the connecting pipe 17 to receive clean water delivered by the water pump 12 and to flush the inside of the collection box 4, the auxiliary frame 10 and auxiliary strips 9 from multiple angles. The vibrating motor 3, the flushing pipe 7 and the inclined plane of the collection box 4 form a triple cleaning structure, which effectively reduces the residue of foam and fine pyrite particles on the inner wall of the collection box 4 and the surface of the auxiliary components, reduces the risk of equipment scaling, and extends service life. The flow meter 16 monitors the water flow in real time to ensure stable flushing effect, avoid water waste, and protect the safe operation of the water pump 12.

[0021] Example 2: Figures 1-4 As shown, a drain pipe 11 and a water inlet pipe 14 are fixedly connected to the outer wall of the water tank 13. A limit plate 15 is engaged at the top of the water tank 13. A servo motor 18 is fixedly connected to one end of the limit plate 15. A lead screw 19 is fixedly connected to one end of the output shaft of the servo motor 18. One end of the lead screw 19 is rotatably connected to the limit plate 15. A U-shaped frame 21 is threadedly connected to the lead screw 19. The top of the U-shaped frame 21 passes through the limit plate 15. The U-shaped frame 21 is slidably connected to the limit plate 15. A filter screen 20 and a filter screen 22 are fixedly connected to the bottom of the limit plate 15. Both the filter screen 20 and the filter screen 22 are slidably connected to the U-shaped frame 21.

[0022] The inlet pipe 14 is fixedly connected to the outer wall of the water tank 13. A one-way valve is installed on the pipe to replenish clean water to the water tank 13. When replenishing water, the water flow must first pass through filter screen 22 and filter screen 20 before entering the water tank 13 for pumping by the water pump 12. Filter screen 20 and filter screen 22 form a dual filtration structure; filter screen 22 is the primary filter and filter screen 20 is the secondary filter, together intercepting impurities in the replenishing water to prevent impurities from entering the water pump 12 or flushing pipe 7 and causing blockage. The U-shaped frame 21 slides with filter screen 20 and filter screen 22. Driven by the screw 19, it moves horizontally along the limit plate 15 to scrape and clean both sides of filter screen 22 and the side of filter screen 20 near filter screen 22. The cleaning process involves removing impurities from the filter screen. The drain pipe 11 is fixedly connected to the outer wall of the water tank 13 to discharge wastewater generated during the filter screen cleaning process, preventing impurities from accumulating inside the water tank 13. The servo motor 18, lead screw 19, and U-shaped frame 21 form an automatic cleaning mechanism that can complete cleaning without disassembling the filter screen, reducing maintenance workload and downtime, and improving the continuous operation capability of the equipment. The U-shaped frame 21 slides and fits against filter screen 10 and filter screen 22, and the scraping range covers the key contaminated surfaces of the filter screen, resulting in more thorough cleaning and extending the service life of the filter screen. The cooperation between the one-way valve of the inlet pipe 14 and the drain pipe 11 enables independent control of water replenishment and sewage discharge, preventing sewage backflow and ensuring the continuous cleanliness of the water in the water tank 13.

[0023] The operation and working principle of this device are as follows: First, when the flotation machine 1 is in use, the scraper 6 scrapes out the foam generated during the separation of sulfur and iron, which is then guided into the collection box 4 by the guide plate 5. An extraction device is connected to the end of the discharge pipe 2. Simultaneously, a cyclone dewatering device can be installed between the discharge pipe 2 and the drying equipment to extract the foam from the collection box 4. The hydraulic push rod 8 drives the auxiliary frame 10 and auxiliary strip 9 downwards, pressing down on the foam. When cleaning the inside of the collection box 4 is required, the water pump 12 draws water from the water tank 13 and sends it into the flushing pipe 7 through the connecting pipe 17. The water is then sprayed out through nozzles at the bottom of the flushing pipe 7 in different directions, cleaning the inside of the collection box 4, as well as the auxiliary frame 10 and auxiliary strip 9. The 9-strip rinse and the 3-vibration motor vibrates the collection box 4 to reduce the residue of foam and fine pyrite particles inside the collection box 4. The one-way valve on the inlet pipe 14 is opened, and water can be added to the water tank 13 through the inlet pipe 14. The water is filtered by the second filter screen 22 and the first filter screen 20 before it can be drawn by the water pump 12. When it is necessary to clean the second filter screen 22 and the first filter screen 20, the servo motor 18 is started by the external controller. The servo motor 18 drives the lead screw 19 to rotate, and the U-shaped frame 21 moves along the limit plate 15 to scrape and clean both sides of the second filter screen 22 and the side of the first filter screen 20 close to the second filter screen 22. The sewage can be discharged from the drain pipe 11.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
