Description

Technical Field

[0001] The utility model relates to the technical field of magnesite processing, in particular to a flotation device for magnesite processing. Background Art

[0002] Magnesite is a magnesium carbonate mineral, which is the main source of magnesium. When a solution containing magnesium acts on calcite, calcite will be transformed into magnesite, so magnesite also belongs to the calcite family. Rocks rich in magnesium will also change into magnesite. Magnesite often contains iron, which is the result of iron or manganese replacing magnesium. Magnesite is white or grayish white with a glassy luster, and iron-containing magnesite will appear yellow to brown. When extracting magnesium from magnesite in industrial production, an essential step is to use a flotation machine. The existing flotation machine scraper is too large, which can easily cause the extract to splash, and the scraper is easy to stick to the sticky extract, which seriously affects the extraction efficiency.

[0003] For example, Chinese patent announcement number CN215429618U discloses a flotation device for processing magnesite. When in use, first fill the material into the processing tank from the material filling port, and then fill water into the material filling port from the water filling port to assist in material discharge and prevent blockage. A regulator is added into the processing tank at the dosing port to promote the reaction of the magnesite. After filling and reacting for a period of time, the motor on the side wall support plate of the support plate is turned on, and the rotation of the motor drives the rotation of the shaft. Taking the figure as an example, the counterclockwise rotation of the shaft drives the scraper connected to the fixed block to rotate counterclockwise. Since the distance from the top of the scraper to the upper end of the partition plate to the shaft is equal, the scraper can scrape the extracted material in the processing tank onto the drainage plate connected to the side wall of the partition plate. Since a limit plate is provided on the upper surface of the partition plate, baffles are installed on both sides of the drainage plate, and the drainage plate is inclined toward the collecting tank, the extracted material will flow into the collecting tank along the drainage plate, and then the extracted material will be collected through the discharge port. Among them, the scraper will be sticky and viscous after working for a long time, so it can be cleaned by a spray structure to speed up the production of the extracted material.

[0004] However, the flotation device for magnesite processing in the above application is not provided with a corresponding stirring mechanism, which accelerates the reaction between the regulator and the ore pulp, and may affect the flotation efficiency. In addition, there will be residual slurry on the surface of the floated magnesite ore, which needs to be processed. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a flotation device for magnesite processing. Utility Model Content

[0006] The purpose of the utility model is to provide a flotation device for processing magnesite ore, so as to solve the problem that the flotation device for processing magnesite ore proposed in the above-mentioned background technology is not provided with a corresponding stirring mechanism, which accelerates the reaction between the regulator and the ore pulp, may affect the flotation efficiency, and there will be residual slurry on the surface of the floated magnesite ore, which needs to be treated.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flotation device for processing magnesite, comprising a flotation tank and a support frame, wherein the support frame is fixedly connected to the top of the flotation tank, a flotation device is arranged on the support frame, and a filtering device is arranged on the outside of the flotation tank.

[0008] The flotation device comprises a stirring unit and an aeration unit.

[0009] The stirring unit includes a driving motor, a transmission member, a stirring shaft, and a stirring plate. The driving motor is installed on the right side of the upper surface of the support frame, the transmission member is connected to the output end of the driving motor, and the stirring shaft is installed inside the transmission member. Two groups of stirring plates are vertically and equidistantly fixedly connected to the outer surface of the stirring shaft. Starting the driving motor drives the worm in the transmission member to rotate, and then drives the worm gear meshing with it to rotate, thereby driving the stirring shaft inside the worm gear to rotate, and then drives the stirring plate on the outer surface of the stirring shaft to rotate, so as to achieve a sufficient mixing reaction of the ore pulp and additives inside the flotation tank.

[0010] A further improvement is that a sealed bearing is installed at the center of the upper surface of the support frame, the stirring shaft is rotatably connected to the inside of the sealed bearing, and its bottom extends into the inside of the flotation tank, so that the stirring shaft rotates inside the sealed bearing.

[0011] A further improvement is that the aeration unit includes a blower, an air inlet pipe, an exhaust pipe, and a nozzle. The blower is installed on the left side of the upper surface of the support frame, the air inlet pipe is fixedly connected to the air outlet of the blower, five exhaust pipes are fixedly connected to the bottom of the outer surface of the stirring shaft in a ring shape, and several nozzles are fixedly connected to the top of the outer surface of the exhaust pipe at equal distances horizontally.

[0012] A further improvement is that an air inlet channel is opened inside the stirring shaft, the bottom of the air inlet pipe is connected to the top of the air inlet channel through a bearing, the exhaust pipe is communicated with the air inlet channel, and the blower is started to blow air through the air inlet pipe to the inside of the air inlet channel, and then flows to the nozzle on the exhaust pipe to be sprayed out, thereby aerating the slurry and improving the efficiency of flotation.

[0013] A further improvement is that the outer surface of the stirring plate is evenly penetrated with spoiler holes, and the top of the outer surface of the stirring shaft is fixedly connected to a flotation scraper. When the stirring plate rotates, the spoiler holes cut and disrupt the slurry to improve the stirring and mixing effect. When the stirring shaft rotates, the flotation scraper is driven to rotate to scrape out the dolomite floating on the top of the slurry to complete the flotation work.

[0014] A further improvement lies in the material receiving unit and the filtering unit of the filtering device.

[0015] The material receiving unit includes a material receiving trough, a material discharging pipe, and an electric valve. The material receiving trough is fixedly connected to the upper part of the outer surface of the flotation tank, the material discharging pipe is fixedly connected to the bottom of the left outer surface of the material receiving trough, and the electric valve is installed on the outer surface of the material discharging pipe. The magnesite scraped by the flotation scraper is discharged into the interior of the material receiving trough. The electric valve is started to lift the magnesite to the material discharging pipe for discharge.

[0016] A further improvement is that the filtration unit includes a water filter port, a filter screen, and a water collecting tank. The water filter port is opened at the left bottom of the material receiving trough, the filter screen is installed inside the water filter port, and the water collecting tank is placed below the water filter port. When the magnesite is discharged into the material receiving trough, the water contained therein is filtered out through the filter screen of the water filter port and flows into the water collecting tank, thereby filtering the floated magnesite, which is more convenient for subsequent processing.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1.

When the stirring shaft rotates, the flotation scraper is driven to rotate to scrape out the magnesite floating on the top of the slurry to complete the flotation work.

[0020] 3. The flotation device for processing magnesite, when the magnesite is discharged into the receiving tank, the water contained in it is filtered out through the filter screen at the water filter port and flows into the water collecting tank, thereby filtering the floated magnesite, which is more convenient for subsequent processing.
