Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment and relates to a flotation machine scraper device which can be maintained during operation. Background Art

[0002] In the mineral processing industry, the main equipment for flotation operations is the flotation machine. A flotation scraper device is installed on the side of the flotation cell of the existing flotation machine. The flotation scraper device includes a motor, a reducer, a rotating shaft, a bearing seat and a scraper. The scraper is installed on the rotating shaft and is used to scrape the flotation foam on the upper end of the liquid surface in the flotation cell and drop it into the collecting tank of the flotation machine for enrichment to obtain a concentrate.

[0003] The existing flotation machine scraper device is a rotating shaft that drives multiple scrapers to rotate. After a period of production, the scrapers usually fall off due to corrosion of the scraper screws, bending and breaking of the scraper, and breaking of the scraper connecting plate. There are two existing treatment methods: one is to wait until the maintenance period for maintenance, which will cause the flotation foam at the damaged scraper to be unable to be scraped out in time, affecting the yield and causing long-term fluctuations in indicators; the other is to shut down the flotation scraper device in time for maintenance, but during the maintenance period, the entire row of scrapers stops running, affecting the flotation foam yield, resulting in the inability to carry out the flotation machine process normally, causing large fluctuations in the shift indicators. Utility Model Content

[0004] The utility model aims to solve the problem of the existing technology by providing a flotation machine scraper device that can be repaired during operation, thereby solving the problem that the existing flotation machine scraper device cannot repair the damaged scraper during operation, thereby reducing the flotation foam yield.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A flotation machine scraper device that can be maintained during operation comprises an inner main shaft of the scraper, a side of the inner main shaft of the scraper is provided with an outer main shaft of the scraper, and the two are connected by a fixing screw and a fixing nut, scrapers are symmetrically provided on both sides of the outer main shaft of the scraper, and the two are connected by a connecting plate, the connecting plate and the scraper are connected by a plurality of scraper screws, bearings are provided at the ends of the outer main shaft of the scraper, and a dust box is provided on the outer side of the bearing.

[0007] Furthermore, a flotation machine scraper device capable of being maintained during operation also includes a motor, a reducer is provided on the side of the motor, and the two are in transmission connection, and the reducer is in transmission connection with the main shaft in the scraper.

[0008] Furthermore, the dustproof box comprises an upper box cover and a lower box cover, and the two are movably connected via a hinge.

[0009] Furthermore, the upper box cover and the lower box cover are combined to form two through holes, which are used to penetrate the inner main shaft of the scraper and the outer main shaft of the scraper respectively.

[0010] Furthermore, the upper box cover and the lower box cover are both provided with lock buckles.

[0011] The beneficial effects of the utility model are:

[0012] The utility model can fix the damaged scraper group and perform maintenance by setting multiple groups of bearings and the outer main shaft of the scraper on the inner main shaft of the scraper, without affecting the rotation of other bearings and the outer main shaft of the scraper, so as to ensure the flotation foam yield; in addition, the utility model sets a bearing dust box to effectively prevent on-site dust from entering the bearing and prevent the bearing from rotating insensitively. The utility model has the advantages of simple operation and convenient maintenance, and is particularly suitable for flotation machines with coaxial multiple scrapers used in ore dressing plants with large daily processing capacity, reducing the impact on technical indicators.

[0018] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0019] like Figure 1 and 2As shown, a flotation machine scraper device that can be maintained during operation includes a scraper inner main shaft 3, and a scraper outer main shaft 8 is provided on the side of the scraper inner main shaft 3, and the two are connected by a fixing screw 10 and a fixing nut 11; specifically, the sides of the scraper inner main shaft 3 and the scraper outer main shaft 8 are provided with insertion holes, and the insertion holes are used to insert the fixing screw 10. After the fixing screw 10 connects the scraper inner main shaft 3 and the scraper outer main shaft 8, its two ends are fixedly connected by the fixing nut 11, at this time, the scraper inner main shaft 3 and the scraper outer main shaft 8 cannot slide relative to each other, when the fixing screw 10 and the fixing nut 11 are removed, the scraper inner main shaft 3 and the scraper outer main shaft 8 can slide relative to each other.

[0020] Scrapers 6 are symmetrically arranged on both sides of the scraper outer main shaft 8, and the two are connected by a connecting plate 4. The connecting plate 4 and the scraper 6 are connected by a plurality of scraper screws 5. Bearings 7 are arranged at the ends of the scraper outer main shaft 8, and a dust box 9 is arranged on the outside of the bearing 7.

[0021] The utility model further comprises a motor 1, a reducer 2 is arranged on the side of the motor 1, and the two are in transmission connection, and the reducer 2 is in transmission connection with a main shaft 3 in the scraper.

[0022] like Figure 3 As shown, the dustproof box 9 includes an upper box cover 12 and a lower box cover 13, and the two are movably connected by a hinge. The upper box cover 12 and the lower box cover 13 are combined to form two through holes, which are used to penetrate the scraper inner main shaft 3 and the scraper outer main shaft 8 respectively. In addition, the upper box cover 12 and the lower box cover 13 are both provided with a lock 14.

[0023] like Figure 4 As shown, during the use of the utility model, the fixed screw 10 fixes the scraper inner main shaft 3 and the scraper outer main shaft 8, so that they rotate in the same direction, so that the scraper 6 rotates with the scraper inner main shaft 3, and the flotation foam is scraped into the foam collecting tank in time. If there are problems such as corrosion and falling of the scraper screws, bending and breaking of the scraper, and breaking of the scraper connecting plate, the motor 1 is turned off, and the fixed screw 10 is pulled out for maintenance. Due to the effect of the bearing 7 between the inner main shaft 3 and the outer main shaft 8, when the scraper 6 is manually fixed, when the scraper inner main shaft 3 rotates, the scraper outer main shaft 8 can remain fixed. At this time, the motor 1 is turned on, the scraper at the damaged part does not rotate, and other coaxial scraper units operate normally, the flotation machine process can be carried out normally, and the large fluctuation of the on-duty indicators is reduced.
