Description

Technical Field

[0001] This application relates to the field of flotation machine feeding technology, and in particular to an adjustable uniform feeding device for flotation machines. Background Technology

[0002] Flotation machines are essential devices for flotation. After the slurry is fully aerated and agitated, the valuable minerals are enriched, completing the flotation process. A crucial step in the process is the selection and operation of flotation reagents to achieve the desired mineral processing objective. Flotation columns and flotation machines are commonly used flotation equipment. The structure of a flotation column involves air being fed from below and the slurry from above. Due to gravity, the slurry slowly descends, and the valuable minerals adhere to the rising air bubbles during this descent, floating to the surface and being scraped out by scrapers into the froth tank, completing the entire separation process. Currently, manufacturers use a double-blade scraper design, which results in less material being scraped out per unit time. In our actual production, we have found that adding more scrapers can effectively improve scraping efficiency, increasing yield and quality. Utility Model Content

[0003] To address the issue that the use of a dual-blade scraper design results in less material being scraped off per unit time, this application provides an adjustable uniform feeding device for flotation machines.

[0004] The adjustable uniform feeding device for a flotation machine provided in this application adopts the following technical solution:

[0005] An adjustable uniform feeding device for a flotation machine includes scrapers. Each of the scrapers has a plurality of threaded holes on one side, and the threaded holes are symmetrically distributed on one side. The scrapers are symmetrically distributed, and each of the scrapers has two connecting blocks bolted to one side. Each of the connecting blocks has a lower connecting sleeve welded to one side, and an upper connecting sleeve is bolted to the top surface of each lower connecting sleeve. Threaded holes are provided on both sides of the upper and lower connecting sleeves.

[0006] Preferably, a rotating shaft is fitted on one side of both the upper and lower connecting sleeves, and the bolt passes through and connects the upper connecting sleeve to the lower connecting sleeve from the outside. The curvature of one side of the upper and lower connecting sleeves is closer to the curvature of the outer side of the rotating shaft.

[0007] Preferably, the scrapers are all of equal volume, all of the scrapers are relatively thin, and all of the scrapers are made of stainless steel.

[0008] Preferably, the top surface of the connecting block of the lower connecting sleeve is provided with an elliptical hole, and the area of ​​the elliptical hole of the connecting block is equal to the diameter of one and a half bolts.

[0009] Preferably, the two upper connecting sleeves and the lower connecting sleeve are a group with the two scrapers, and auxiliary scraping blocks are bolted to both sides of the scrapers.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. The upper and lower connecting sleeves rotate with the rotating shaft, which in turn rotates the connecting block and the scraper. The rotation of the scraper scrapes out the air bubbles in the mineral into the foam tank. Increasing the number of scrapers makes it easier to remove air bubbles from the mineral. Compared with the existing technology, this method has the effect of improving the efficiency of air bubble removal and enhancing the quality.

[0012] 2. During the process of scraping the mineral into the foam tank by the scraper, the air bubbles on the surface of the mineral gradually decrease. The auxiliary scraper is beneficial for surface air bubble treatment of some special ores. Compared with the existing technology, it has the effect of improving scraping efficiency, increasing yield and quality. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses an adjustable uniform feeding device for a flotation machine, referring to... Figure 1 and Figure 2 as well as Figure 3The system includes scraper 1, with several threaded holes on one side of each scraper 1. These threaded holes are symmetrically distributed on one side. Each scraper 1 has two connecting blocks 2 bolted to one side. Each connecting block 2 has a lower connecting sleeve 3 welded to one side. Each lower connecting sleeve 3 has an upper connecting sleeve 4 bolted to its top surface. Both sides of the upper connecting sleeve 4 and the lower connecting sleeve 3 have threaded holes 2. Rotation of the shaft 5 causes the upper connecting sleeve 4 and the lower connecting sleeve 3 to rotate, further rotating the connecting blocks 2 and the scraper 1. The rotation of the scraper 1 scrapes out the air bubbles of the mineral into the foam tank. By increasing the number of scrapers 1, the efficiency of scraping out air bubbles is enhanced, and the quality is improved.

[0020] Reference Figure 3 A rotating shaft 5 is fitted on one side of both the upper connecting sleeve 4 and the lower connecting sleeve 3. Bolts pass through the outer side of the upper connecting sleeve 4 and the lower connecting sleeve 3 to connect them. The curvature of one side of the upper connecting sleeve 4 and the lower connecting sleeve 3 is closer to the curvature of the outer side of the rotating shaft 5. The upper connecting sleeve 4 and the lower connecting sleeve 3 wrap around the outer side of the rotating shaft 5. The upper connecting sleeve 4, the lower connecting sleeve 3 and the rotating shaft 5 are more closely fitted and fixed by rotating the bolts, which facilitates the rotation of the scraper 1 later. In order to make the structure of the upper connecting sleeve 4, the lower connecting sleeve 3 and the rotating shaft 5 more stable, bolts can be passed through the upper connecting sleeve 4 or the lower connecting sleeve 3 to connect and rotate the rotating shaft 5.

[0021] Reference Figure 1 The scrapers 1 are all of equal volume, all of the scrapers 1 are relatively thin, and all of the scrapers 1 are made of stainless steel. Stainless steel is tough and convenient for long-term use of the scrapers 1.

[0022] Reference Figure 3 The top surface of the connecting block 2 of the lower connecting sleeve 3 is provided with an elliptical hole. The area of ​​the elliptical hole of the connecting block 2 is equal to the diameter of one and a half bolts. The elliptical hole of the connecting block 2 is conducive to fixing and connecting the upper connecting sleeve 4 and the lower connecting sleeve 3 with bolts.

[0023] Reference Figure 2 and Figure 4 The two upper connecting sleeves 4 and the lower connecting sleeve 3 are a group with the two scrapers 1. The two sides of the scraper 1 are bolted with auxiliary scraper blocks 6. During the process of scraping the mineral out to the foam tank by the scraper 1, the bubbles on the surface of the mineral gradually decrease, so that the auxiliary scraper blocks 6 can help to treat the surface bubbles of some special ores, thereby improving scraping efficiency, yield and quality.

[0024] The implementation principle of an adjustable uniform feeding device for a flotation machine according to an embodiment of this application is as follows: First, the upper connecting sleeve 4 and the lower connecting sleeve 3 wrap around the outside of the rotating shaft 5, and the upper connecting sleeve 4, the lower connecting sleeve 3 and the rotating shaft 5 are more closely fitted and fixed by rotating bolts. Then, the connecting block 2 and the scraper 1 are fixed by bolts. Second, the upper connecting sleeve 4 and the lower connecting sleeve 3 are rotated by rotating the rotating shaft 5, which further rotates the connecting block 2 and the scraper 1. The rotation of the scraper 1 scrapes the air bubbles of the minerals out to the foam tank. Increasing the number of scrapers 1 makes it faster to clean the air bubbles of the minerals. Finally, during the process of scraping the minerals out to the foam tank by the scraper 1, the air bubbles on the surface of the minerals gradually decrease. The auxiliary scraper 6 is beneficial for surface air bubble treatment of some special ores.
