Description :

　　1、 Product Name:0.75 liter flotation machine XFD-0.75 single cell flotation machine

　　IIXFD-0.75 Single Cell Flotation MachineIntroduction: After thorough mixing of coal slurry and reagents, they are fed into the bottom of the chamber of a single tank flotation machine. After the impeller rotates, negative pressure is formed in the wheel cavity, causing the slurry at the bottom of the tank and in the tank to enter the mixing zone through the lower and upper suction ports of the impeller, respectively. This also allows air to enter the mixing zone along the air guide sleeve, where the slurry, air, and reagents mix. Under the centrifugal force of the impeller, the mixed slurry enters the mineralized area, the air forms bubbles and is crushed, fully contacts with the coal particles, forming mineralized bubbles. Under the action of the stator and turbulence plate, it is evenly distributed on the section of the tank body, and moves upward into the separation area. The foam layer is formed by the enrichment, and discharged by the foam scraping mechanism, forming the cleaned coal foam. The unmineralized coal particles on the bottom of the trough will be mixed, mineralized, and separated again through the circulation holes and upper suction ports. The part of the slurry under the groove that is not sucked in by the impeller enters the groove under the second chamber through the intermediate ore box buried in the slurry, completes the entire process of the chamber, and then enters the third chamber,0.75 liter flotation machineThis cycle repeats, and the slurry enters the tailings tank after passing through one room to discharge the final tailings.

　　Check the direction of rotation of the spindle, it must rotate clockwise. If not, the power phase sequence should be switched to make the motor rotate clockwise before starting to work.

　　First mix the ore sample with water and pour it into the tank. Start the motor, and the main shaft rotates. The impeller in the tank can start mixing. Then open the valve for inflation. After adding the required agent, foam can be formed. Turn on the scraper motor switch to rotate the scraper. Then the foam can be hung out of the notch, and the material box is placed on the workbench. After the scraped foam is treated, the desired mineral can be obtained.

4XFD-0.75 Single Cell Flotation MachineDesign of each component

　　To meet the above design requirements, the various parts of the existing single cell flotation machine have been improved and designed. According to the sorting tank capacity, it is divided into four models: 0.5L-0.75L, 1.0L, and 1.5L. The specific design is as follows [2]

　　Transmission part and body

　　to ensureXFD-0.75 Single Cell Flotation MachineStable operation of the body and requirements for appearance design,XFD-0.75 Single Cell Flotation MachineThe transmission part adopts a rear motor, which drives the spindle to rotate with a belt. The body is made of stainless steel plate, initially designed as a 1.5mm thick stainless steel plate. However, after trial production experiments, it was found that the body was too light and unstable when the spindle speed was higher than 2000r/min. Therefore, it was changed to a 2mm thick stainless steel plate and a 10kg counterweight was added to the lower part of the body

　　At the same time, in order to increase the universality of the design and reduce the manufacturing cost, the four types of flotation machines adopt a universal body and transmission part. The existing series of flotation machines use organic glass protective devices, which have good visual effects, but are often damaged during use and have certain safety hazards. The wood optimization design plans to optimize the material and installation form of the protective device, with the material changed from organic glass to carbon steel plate, and the installation method changed from four column supports to two side U-port plug-in type.
