[0025] The specific working process of the gas bubble generating device in the quartz sand flotation process of the utility model is as follows:

[0026] I. Initial preparation

[0027] Ensure that all components such as the flotation tank, stirring mechanism, support tube, air inlet tube, one-way air nozzle, air supply mechanism, drive mechanism, and partition cover are correctly installed and connected.

[0028] Mix an appropriate amount of quartz sand with water and flotation reagents to form the flotation medium, and pour it into the flotation tank. The selection and amount of flotation reagents should be determined according to the characteristics of the quartz sand and the flotation requirements.

[0029] II. Start-up and operation

[0030] Turn on the air pump and deliver the gas to the air inlet tube through the air supply hose. At this time, the gas accumulates in the air inlet tube and is ready to be released.

[0031] Start the drive motor and rotate the air inlet tube through the transmission gear. The rotating air inlet tube helps to distribute the gas more evenly in the pipeline and increases the dispersibility of the bubbles.

[0032] Turn on the reduction motor to drive the stirring shaft to rotate, which in turn drives the stirring paddle to stir in the flotation tank. The stirring process helps to fully mix the quartz sand with the flotation medium and evenly distribute the bubbles in the material.

[0033] Start the electric push rod to drive the push rod end to move the support tube and the air inlet tube on it up and down reciprocally. This movement helps to adjust the height and frequency of bubble release, thereby optimizing the flotation effect.

[0034] III. Flotation process

[0035] When the gas enters the flotation tank through the air inlet tube, it is uniformly released in the form of tiny bubbles into the flotation medium under the action of the one-way air nozzle. These bubbles will carry hydrophobic quartz sand particles to the surface of the flotation tank, forming a foam layer.

[0036] During the rising of the bubbles, hydrophobic quartz sand particles will adhere to the bubbles. As the bubbles rise and accumulate, these particles will gradually form larger foam clumps. When the foam layer reaches a certain thickness, it can be removed from the surface of the flotation tank through a scraper or other device, thereby achieving the separation of quartz sand and impurities.

[0037] During the entire flotation process, the stirring mechanism will continue to work to ensure the full mixing of quartz sand and flotation medium and the uniform distribution of bubbles.

[0038] IV. End and cleaning

[0039] When the flotation process is complete, the drive mechanism, stirring mechanism, support mechanism, and air supply mechanism, etc. need to be turned off in sequence.

[0040] The cleaning and maintenance of the flotation tank, stirring mechanism, support pipe, air inlet pipe and other components are performed to ensure the long-term stable operation of the equipment and the smooth progress of the next use.

[0041] In summary, the bubble generating device in the quartz sand flotation process realizes efficient and uniform generation and distribution of bubbles and effective separation of quartz sand and impurities through the synergistic work of carefully designed various components and assemblies, which helps to ensure the flotation quality of quartz sand and improve the flotation efficiency.
