Flotation machine impeller cover
zh
Flotation machine is the main equipment for flotation minerals. In order to let you know more about the internal structure of flotation machine, Yufa Machinery will talk about the flotation machine impeller in detail. and the working principle of the cover plate, let you understand the function of the components, and thus understand that the impeller and cover plate of the flotation machine are the key components of this flotation machine, which determine the degree of aeration of the slurry. The bottom plate of the impeller is a disc with six rectangular blades extending in the radial direction. There is a hub in the center that can be sleeved on the drive shaft, and the center is lined with babbitt alloy. The impeller is either cast iron or has an iron core lined with rubber or polyurethane. The impeller is fastened to the lower end of the main shaft with a nut. Its function is
zh.
It forms a vacuum chamber similar to a pump with the cover plate to create a negative pressure area, allowing the slurry to flow by itself, the air to self-absorb, and the slurry in the tank circulates.
zh
The rotation of the impeller breaks the inhaled air into bubbles and evenly disperses them in the slurry. The stirring of the impeller causes the mineral particles to be suspended and fully contacted with the bubbles
zh
causing the mineral particles to be suspended
zh.
to fully dissolve and disperse the medicine.
zh
The cover plate is a cast iron or rubber-lined hollow disc with
zh
zh
a slurry circulation hole. There are
zh
zh
guide blades arranged diagonally on the bottom edge at an angle
zh
to the radius, and their inclination direction is consistent with the direction of rotation of the impeller. The function of the cover is
zh.
It forms a pump with the impeller to produce aeration, that is, when the slurry is thrown out by the impeller, a negative pressure suction is formed under the cover
zh.
The guide blades guide the thrown out slurry, reduce eddy currents, that is, reduce hydraulic losses, and play some stabilizing role
zh.
Adjust the amount of slurry entering the flotation machine impeller to increase the slurry volume. Internal circulation
zh.
Ensure that the impeller is not buried by the ore when the flotation machine is stopped, thereby preventing the motor from being overloaded when it is started.
