Description

Technical Field

[0001] This utility model relates to the field of flotation device technology, specifically a high-temperature, high-oil wastewater flotation device. Background Technology

[0002] A flotation unit is an important piece of equipment used in mineral processing and beneficiation. Its main function is to separate minerals through the interaction between bubbles and mineral particles. A flotation unit typically consists of a stirring mechanism, an aeration device, a slurry supply system, and a froth scraping device. During operation, the slurry and reagents are mixed and then enter the flotation cell. The negative pressure generated by the rotating impeller draws in air, forming a large number of bubbles. Mineral particles adhere to these bubbles and rise to the surface, forming a froth layer. The scraper removes the froth, thus achieving mineral separation. Flotation units can be classified into various types, including mechanically agitated, aerated, countercurrent, and mixed-flow types.

[0003] A flotation device, as disclosed in publication number CN221016620U, includes a stirring tank, a power unit, a transmission unit, and a stirring mechanism. The stirring tank is a polygonal cone shape, with a feed inlet and an air inlet sequentially located on its top wall. The power unit is mounted on the stirring tank, with its output rotatably connected to the transmission unit. The output of the transmission unit is rotatably connected to the stirring mechanism, which is located inside the stirring tank. Its output is located at the cone-shaped bottom of the stirring tank, and the stirring mechanism is connected to the air inlet. This invention, through the coordinated operation of the stirring tank, power unit, transmission unit, and stirring mechanism, ensures that the slurry in the stirring tank is not dispersed to the bottom periphery under centrifugal force, allowing for thorough mixing and separation. The feed inlet on the stirring tank prevents the slurry from impacting the components of the stirring mechanism, thus extending the service life of each component and improving flotation efficiency.

[0004] The above-mentioned device has poor bubble stability during use, and oil stains easily adhere to the tank wall; therefore, we propose a high-temperature, high-oil wastewater flotation device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature, high-oil wastewater flotation device to solve the problems mentioned in the background art, such as poor bubble stability and easy adhesion of oil to the tank wall.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature, high-oil wastewater flotation device, comprising a separation tank, a support block at the upper end of the separation tank, a flotation device inside the separation tank, a motor at the upper end of the flotation device, a rotating shaft at the lower end of the flotation device, a support plate at the lower end of the rotating shaft, the support plate inside the separation tank, an ultrasonic device at the lower end of the support plate, and a cleaning device inside the separation tank.

[0007] Preferably, the lower end of the motor is provided with a motor bracket, which is mounted on a support block.

[0008] Preferably, the ultrasonic device includes an ultrasonic generator, connecting pipes, ultrasonic transducers, a vibrating steel plate, a discharge pipe, and a controller. The ultrasonic generator is located at the lower end of the inner side of the separation tank. Four sets of connecting pipes are provided at the upper end of the ultrasonic generator. Each of the four sets of connecting pipes is equipped with an ultrasonic transducer. A vibrating steel plate is provided at the upper end of the ultrasonic transducer. A discharge pipe is provided inside the vibrating steel plate. A controller is provided at the front end of the ultrasonic generator.

[0009] Preferably, the cleaning device includes a rotating component, a rack, a connecting plate, a cleaning plate, and a brush. Two sets of connecting plates are provided, and both sets of connecting plates are disposed inside the separation tank. A cleaning plate is disposed between the two sets of connecting plates. A brush is disposed on the outer side of each cleaning plate, and the brush is in close contact with the inner wall of the separation tank. A rotating component is disposed at the upper end of the upper connecting plate, and a rack is disposed inside the rotating component.

[0010] Preferably, a baffle is provided between the connecting plate and the rotating component, and a feed port is provided at the upper end of the baffle.

[0011] Preferably, a filter plate is provided at the upper end of the vibrating steel plate, and a valve is provided on the outside of the discharge pipe.

[0012] Preferably, a gear is provided inside the baffle, the gear is located outside the flotation device and is connected to a rack and pinion drive.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides an ultrasonic device at the lower end of the flotation device. The ultrasonic transducer causes the vibrating steel plate to vibrate. In conjunction with the flotation device, more micro bubbles can be generated, thereby providing more carriers for flotation and improving flotation efficiency. The vibration generated by the vibrating steel plate can also reduce the liquid film resistance between particles and bubbles, promote the collision and adhesion of particles and bubbles, and improve the flotation recovery rate, thus solving the problem of poor bubble stability.

[0015] (2) The ultrasonic vibration generated by the ultrasonic device can prevent dirt from depositing and growing on the surface of the device, reducing scaling and clogging. Combined with the cleaning device set on the outer side of the inner wall of the separation tank, the motor drives the gear to rotate, thereby rotating the rack connected to the gear transmission, thus cleaning the inner wall of the separation tank, thus solving the problem that oil stains easily stick to the tank wall.
