A new type of flotation machine

Abstract

The invention relates to a novel flotation machine. The novel flotation machine comprises a box, a stirring mechanism and an inflation mechanism. A first supporting frame is arranged on the outer sideof the right side face of the box. A motor is arranged at the upper end of the supporting frame. An output shaft of the motor is provided with a drive wheel. The stirring mechanism comprises a hollowrotation shaft vertically arranged. The upper portion of the hollow rotation shaft stretches out of the box. A bearing body is arranged at the upper end of the box. The hollow rotation shaft is sleeved with the bearing body. A driven belt wheel is arranged above the bearing body. The hollow rotation shaft is sleeved with the driven belt wheel. The middle lower portion of the hollow rotation shaftis arranged in the box. A turbulent flow cover is arranged at the lower portion of the hollow rotation shaft and sleeves the hollow rotation shaft. The inflation mechanism comprises a first air inletpipe, a casing pipe, a second air inlet pipe, an air inlet connecting pipe and a sealing structure. Through changing of a traditional inflation manner, pressured air can be more directly conveyed into the flotation machine, and the inflation effect is better.

Description

technical field [0001] The invention relates to the technical field of mining equipment manufacturing, in particular to a novel flotation machine. Background technique [0002] The flotation machine is a kind of mineral processing equipment. The flotation machine used in the non-ferrous metal, ferrous metal and non-metallic mineral separation industry usually consists of a motor device, a main shaft part and a tank part. When the flotation machine is working, the motor device drives the main shaft impeller to rotate and stir the pulp in the tank, and at the same time, the air filled in the tank is cut into small bubbles, which collide with the mineral particles in the pulp to form mineralized bubbles, and the mineralized bubbles rise to The liquid surface of the slurry forms a foam layer to complete the flotation process. Since the gas filled into the flotation machine has a certain pressure, this pressure is related to the immersion depth of the impeller. Generally, the lar...

Problems solved by technology

When the flotation machine is working, the motor device drives the main shaft impeller to rotate and stir the pulp in the tank, and at the same time, the air filled in the tank is cut into small bubbles, which collide with the mineral particles in the pulp to form mineralized bubbles, and the mineralized bubbles rise to The liquid surface of the slurry forms a foam layer to complete the flotation process. Since the gas filled into the flotation machine has a certain pressure, this pressure is related to the immersion depth of the impeller. Generally, the larger the flotation machine, the greater the immersion depth of the impeller. The greater the pressure required to fill the gas inside the flotation machine, when the existing flotation machine is inflated, the compressed air first enters the inside of the main shaft bearing body, which puts forward high requirements on the sealing effect between the bearing body and the main shaft. The cost will inevitably increase, and it will also affect the follow-up operation cost. Using this inflation method, the processing of the main shaft and bearing body of the flotation machine is very difficult.
