[0019] Mixing bin 2 is provided with online liquid level meter 21, the water inlet pipe 11 and the belt conveyor 14 of the feeding mechanism 1 respectively send water and material into the mixing bin 2, the online liquid level meter 21 is connected with slurry density controller 6;

[0020] Cyclone 3 is provided with inlet 31 and outlet 32, the material conveying mechanism 4 connects the cyclone inlet 31 with the mixing bin 2, used for sending the slurry in the mixing bin 2 into the cyclone 3 for separation;

[0021] Material conveying mechanism 4 includes slurry pipe 41, slurry pump 42 and online pressure gauge 43, the slurry pipe 41 connects the mixing bin 2 with the cyclone 3, the slurry pump 42 and online pressure gauge 43 are arranged on the slurry pipe 41, the online pressure gauge 43 is connected with slurry pressure regulator 7, the slurry pressure regulator 7 is connected with slurry pump 42 signal, the slurry pressure of the slurry pump 42 is adjusted to send into the cyclone 3;

[0022] Separation detection mechanism 5 includes image capture device 51 and background plate 52, preferably the image capture device 51 is an industrial camera, the image capture device 51 is arranged at the position which can shoot and acquire the real-time flow picture at the outlet, the background plate 52 is arranged at the outlet, the background plate 52 is light color, used for assisting the image capture device to shoot the real-time flow picture at the outlet, the image capture device is connected with slurry pressure regulator 7 signal;

[0024] The slurry pressure regulator 7 is connected with the material conveying mechanism 5 signal, and is used for adjusting the slurry pressure sent into the cyclone.

[0025] Referring to Figure 1 The working process of the automatic feedback regulation device for the cyclone feeding and discharging state is as follows:

[0026] During the working process of the cyclone 3, the slurry density in the feeding mixing bin 2 is adjusted by the density controller 6, so that the slurry density in the slurry pipe 41 is kept constant during the working process of the cyclone. The amount of the material lacking in the mixing bin 2 is obtained by the online liquid level meter 21, the slurry density controller 6 calculates the amount of the raw material and the water required for configuring the mixed material with a given concentration according to the preset parameters, the slurry density controller 6 adjusts the feeding speed of the belt conveyor 14 and the water feeding speed of the water pump 12 according to the amount of the raw material and the water, and finally confirms the adjustment result according to the detection data fed back by the water content detector 16;

[0027] The slurry density in the feeding mixing bin is adjusted by the density controller 6 to keep the slurry density constant, at this time, the separation effect of the cyclone 3 is only affected by the properties of the raw material and the feeding pressure, and the change of the separation effect caused by the change of the properties of the raw material can also be adjusted by adjusting the feeding pressure, so that the automatic feedback regulation of the cyclone 3 on the discharging state can be realized by the slurry pressure regulator 7;

[0028] During the discharging process of the cyclone 3, the image capture device 51 captures the real-time material flow picture of the cyclone discharge port, and there is a color difference between the material flow and the background plate. The material flow angle of the cyclone 3 can be obtained through the image captured by the image capture device 51, and the material flow angle will be different when the separation effect of the cyclone 3 is different. When the material flow angle is too large, it represents that the content of the raw material in the separated material of the cyclone is less and the water content is more. When the material flow angle is too small, it represents that the content of the raw material in the separated material of the cyclone is more. The slurry pressure regulator 7 adjusts the slurry pressure sent into the cyclone through the slurry pump 42, so as to control the separation effect of the cyclone 3. When the material flow angle is moderate, it represents that the content of the raw material in the separated material of the cyclone is moderate, which is the ideal state, and the slurry pressure is kept at this time.

[0029] The automatic feedback regulation device for the cyclone feeding and discharging state can keep the slurry density sent into the cyclone constant through the slurry density controller 6, the separation detection mechanism detects the separation effect of the cyclone, and then the feeding pressure is adjusted through the slurry pressure regulator 7, so that the slurry density and the feeding pressure can be automatically controlled, the feeding state of the cyclone 4 reaches the expectation, and the online separation effect adjustment is realized quickly and efficiently.
