[0016] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0017] Embodiment 1:

[0018] Please see attached Figure 1 With attached Figure 2As shown, a medium suspension diversion pipe of a three-product heavy medium cyclone sorting system comprises a three-way pipe body 1, wherein the three-way pipe body 1 comprises a feed pipe 2, a discharge pipe 3 and a second-stage discharge pipe 4, wherein the central axes of the feed pipe 2, the discharge pipe 3 and the second-stage discharge pipe 4 are located on the same horizontal plane and an angle of 120° is formed between the central axes of every two pipes, and an angular actuator 5 is arranged above the three-way pipe body 1, wherein the angular actuator 5 is connected with a rotating shaft 6, wherein the rotating shaft 6 passes through the three-way pipe body 1 and extends to the inner cavity of the three-way pipe body 1, and wherein the rotating shaft 6 is connected with a diverter plate 7 disposed in the inner cavity of the three-way pipe body 1, and the angular actuator 5 controls the rotation of the diverter plate 7 through the rotating shaft 6, thereby controlling the medium flow rate between the feed pipe 2 and the discharge pipe 3 and the second-stage discharge pipe 4.

[0019] Please see attached Figure 2 and attached Figure 3 As shown, in the embodiment, the inner diameters of the feed pipe 2, the discharge pipe 3, and the second-stage discharge pipe 4 are the same, and the size of the diverter plate 7 is smaller than the inner diameters of the discharge pipe 3 and the second-stage discharge pipe 4, so that the diverter plate 7 can rotate around the rotating shaft 6 under the control of the angular actuator 5, so that the material entering from the feed pipe 2 can enter the discharge pipe 3 and the second-stage discharge pipe 4 respectively; further, when the problem of gangue carrying coal occurs, for the medium supply port on the second-stage cyclone cylinder, the inflow of the medium under the medium coal screen should be reduced, and the inflow of the medium under the gangue screen should be increased. At this time, the medium under the medium coal screen is controlled to flow inward. The diverter plate 7 of the diverter pipe in the pipeline is biased toward the second-stage discharge pipe 4, and the diverter plate 7 of the diverter pipe of the combined medium pipeline under the gangue screen is biased toward the discharge pipe 3, thereby increasing the flow rate of the medium flowing to the second-stage discharge pipe 4; when the problem of medium coal carrying gangue occurs, for the medium supply port on the second-stage cyclone cylinder, the inflow of the medium under the medium coal screen should be increased, and the inflow of the medium under the gangue screen should be reduced. At this time, the diverter plate 7 of the diverter pipe in the combined medium pipeline under the medium coal screen is controlled to be biased toward the discharge pipe 3, and the diverter plate 7 of the diverter pipe of the combined medium pipeline under the gangue screen is biased toward the second-stage discharge pipe 4, thereby reducing the flow rate of the medium flowing to the second-stage discharge pipe 4.

[0021] Please see attached Figure 1 As shown, based on Example 1, the diverter plate 7 is V-shaped. After the medium enters the three-body tube 1 through the inlet, it directly contacts the inclined surface of the diverter plate 7. The inclined surface of the diverter plate 7 guides the medium to the discharge pipe 3 or the second-stage discharge pipe 4 to help the medium flow.
