Description

Technical Field

[0001] The utility model relates to the technical field of flotation machine related equipment, in particular to an air-filled flotation machine with a flushing device. Background Art

[0002] In recent years, due to the increasing demand for sulfur concentrate with a grade of more than 48% in the market, the existing pyrite ore has upgraded and transformed the flotation series of the beneficiation line to produce high-quality sulfur concentrate with a grade of more than 48%. The flotation equipment uses a shallow trough overflow flotation machine with high processing efficiency. Through the rotation of the impeller, the supplemented air is dispersed and fully mixed with the inhaled slurry to form mineralized bubbles, and the useful minerals are separated to obtain the required sulfur concentrate minerals. However, during use, due to the low supplementary air pressure, only about 31KPa, and the inhaled slurry is relatively viscous, it is easy to form adhesion and accumulation in the center tube of the flotation machine, affecting the gas supply, resulting in large reagent consumption, poor sorting effect, and unsatisfactory flotation economic and technical indicators. The currently used inflatable flotation machine does not have a flushing purification device, and the slurry often blocks the center tube of the flotation machine, affecting the air supply, and cannot form effective mineralized bubbles, resulting in low sorting efficiency, poor sorting effect, and affecting the economic and technical indicators and economic benefits of mineral processing. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide an air-filled flotation machine with a flushing device.

[0004] The utility model is realized through the following technical scheme: an air-filled flotation machine with a flushing device, comprising a flotation machine system and a flushing device; the flotation machine system comprises a flotation machine cell, a central casing, a main transmission shaft, a transmission pulley, a main motor, an air suction pipe and a control system; the central casing is arranged in the flotation machine cell, and the main transmission shaft is installed in the central casing; one end of the transmission pulley is connected to the main transmission shaft, and the other end thereof is connected to the main motor; the air suction pipe is connected to the central casing and communicates with the central casing; the flushing device comprises a high-pressure nozzle and a pipeline pump connected to recycled water, the pipeline pump is connected to the high-pressure nozzle through a connecting pipe, and the high-pressure nozzle is installed in the central casing; the main motor and the pipeline pump are respectively connected to the control system.

[0005] The pipeline pump provides power for the high-pressure nozzle, which sprays the recycled water to flush the gap between the main drive shaft and the center casing. The high-pressure impact force breaks up the air entering from the suction pipe, and combines with the cyclonic force of the inhaled slurry to quickly clean the slurry attached to the gap between the main drive shaft and the center casing of the flotation machine, thereby ensuring smooth airflow and rapid and stable slurry foaming, achieving the goal of efficient production.

[0006] The connecting pipe is provided with four water pipes, and the four water pipes are arranged in the gap between the central casing and the main transmission shaft, and the high-pressure nozzle is connected to the lower end of the water pipe.

[0007] The four water pipes are evenly arranged around the outer periphery of the main transmission shaft, and the adjacent water pipes are at an angle of 90 degrees with the axis of the main transmission shaft as the baseline. The four water pipes are evenly arranged, so that the high-pressure nozzles are also evenly arranged, and the recycled water is sprayed more evenly.

[0008] The air intake pipe is connected to the central casing in an inclined manner downward, and the lower end of the high-pressure nozzle is flush with the lower end of the air intake pipe.

[0009] The spray angle of the high-pressure nozzle is not less than 15 degrees.

[0010] The control system includes a transmitter and a processor. The central casing is equipped with a pressure gauge, and the pressure gauge is connected to the processor through the transmitter.

[0011] An electric valve is installed between the connecting pipe outside the central casing and the pipeline pump, and the electric valve is connected to the control system.

[0012] The water pipe is made of stainless steel.

[0013] The diameter of the water pipe is 12.0 mm, and the thickness of the pipe wall is 1.0 mm.

[0014] Compared with the prior art, the utility model has the following advantages: the device has a simple structure, is easy to manufacture and install, and is highly practical. It ensures that the mineralized air is stably sucked into the upper impeller cavity through the suction pipe and the central casing, and is mixed with the sucked slurry to form continuous and stable mineralized bubbles, with good mineralization effect, improved sorting efficiency, good sorting effect, and greatly improved mineral processing technical indicators. The device uses the high-pressure nozzle to spray and flush the main drive shaft and the central tube gap of the flotation machine with recycled water. The high-speed impact force is combined with the cyclonic force of the sucked slurry, which can quickly clean the slurry attached to the main drive shaft and the central tube gap of the flotation machine, thereby ensuring smooth airflow and rapid and stable slurry foaming, thereby achieving the purpose of efficient production.

[0020] The pipeline pump 9 provides power for the high-pressure nozzle 7, and the recycled water 8 is sprayed to flush the gap between the main transmission shaft 3 and the central casing 2. The high-pressure impact force is combined with the air entering from the suction pipe 6 to break up the air, and the slurry cyclone force sucked in can quickly clean the slurry attached to the gap between the main transmission shaft 3 and the central casing 2 of the flotation machine, thereby ensuring smooth air flow, rapid and stable slurry foaming, and achieving the purpose of efficient production.

[0021] The connecting pipe is provided with four water pipes, and the four water pipes are arranged in the gap between the central casing 2 and the main transmission shaft 3, and the high-pressure nozzle 7 is connected to the lower end of the water pipe.

[0022] Four water pipes are evenly arranged around the outer periphery of the main transmission shaft 3, and adjacent water pipes are at a 90 degree angle with the axis of the main transmission shaft 3 as the baseline. The four water pipes are evenly arranged, so that the high-pressure nozzles 7 are also evenly arranged, and the recycled water 8 is sprayed more evenly.

[0023] The air suction pipe 6 is connected to the central casing 2 at an angle downward, and the lower end of the high-pressure nozzle 7 is flush with the lower end of the air suction pipe 6 .

[0027] The water pipes are made of stainless steel.

[0028] The diameter of the water pipe is 12.0 mm and its wall thickness is 1.0 mm.

[0029] When the flotation machine system startup time reaches 60 minutes or the pressure in the central casing 2 is higher than 35Kpa, the control system is triggered to control the pipeline pump 9 and the electric valve 13 to open at the same time. After running for 20 seconds, the control system is triggered to control the pipeline pump 9 and the electric valve 13 to close at the same time.

[0030] In this embodiment, the processor 11 is a prior art, so there is no need to carry out a specific structural analysis.
