The number of the discharge ports 4073 is known, a multiple relationship is preset between the flow rate value monitored by the first flow rate monitor 4074 and the flow rate value monitored by the second flow rate monitor 4079, and the multiple relationship is matched with the number and the sum of the discharge ports 4073 and the calibration ports 4078, namely when the number of the discharge ports 4073 is four, in a normal working state, the flow rate value monitored by the first flow rate monitor 4074 is five times that monitored by the second flow rate monitor 4079, and then under the multiple relationship, the alumina powder in the multiple groups of the discharge ports 4073 and the calibration ports 4078 uniformly falls on the top of the discharge conveyor 4092 for subsequent conveying, and when the flow rate value monitored by the second flow rate monitor 4079 is reduced and is less than one fifth of the first flow rate monitor 4074, the internal structure is blocked, and then the discharge rates of the multiple groups of the discharge ports 4073 and the calibration ports 4078 are required to be adjusted.
In practical use, as can be seen from the first embodiment, firstly, the first sieving frame 203 and the second sieving frame 204 inside the sieving mechanism 2 are used to perform vibration sieving on the alumina powder, the sieved alumina powder is fed into the feed hopper 401 by the conveying mechanism 3, the first flow monitor 4074 monitors the flow velocity value, meanwhile, the crushed alumina powder enters the crushing cylinder 407 after passing through the crushing cylinder 402, the crushing auger 4071 rotates and drives the alumina powder to sequentially reach the inside of the plurality of groups of feeding ports 4073 and perform feeding, when the rest alumina powder reaches the calibration port 4078 and finally falls on the top of the feeding conveyor 4092, the second flow monitor 4079 monitors the flow velocity value of the alumina powder inside the calibration port 4078, in this embodiment, four feeding ports 4073 are set, and the calibration port 4078 is only one, so that if the flow velocity value monitored by the second flow velocity monitor 4079 is one fifth of the flow velocity monitor 4074, the components stably operate, and the alumina powder falling on the top of the feeding conveyor 4092 along the feeding ports 4073 and the calibration port 4078 is uniformly spread.
In actual use, when the sieving mechanism 2 is blocked, the amount of alumina powder falling on the top of the conveying mechanism 3 along the sieving mechanism 2 is reduced, the flow rate of the alumina powder entering the feed hopper 401 along the conveying mechanism 3 is reduced, the flow rate value monitored by the first flow rate monitor 4074 is reduced, the flow rate value monitored by the second flow rate monitor 4079 is unchanged, which means that the crushing roller 402 is not blocked at this time, in order to ensure the subsequent crushing and discharging uniformity of the alumina powder, the second driving motor 301 starts to increase the rotation rate, the second driving motor 301 drives the feeding rate of the feeding belt 304 to increase, the rate of the alumina powder on the top of the feeding belt 304 entering the feed hopper 401 is increased, the flow rate value monitored by the first flow rate monitor 4074 is increased to a set initial value, the crushed roller 402 is fully loaded and operated, the crushed alumina powder is discharged to the top of the discharging conveyor 4092 along the discharging opening 4073 and the calibrating opening 4078, and the feeding belt 4092 is carried out.
And when the blockage of the screening mechanism 2 is continuously cleared, the flow speed of the alumina powder entering the feeding hopper 401 is increased under the transmission action of the conveying mechanism 3, the transmission speed of the second driving motor 301 driving the feeding belt 304 is reduced to an initial speed value, and all the components are restored to the initial working state again.
When the inside of the crushing roller 402 is blocked during actual use, the flow rate of the alumina powder entering the feeding hopper 401 along the conveying mechanism 3 is unchanged, the flow rate value monitored by the first flow rate monitor 4074 is unchanged, the flow rate of the alumina powder discharged along the calibration port 4078 is reduced, namely, when the alumina powder in the crushing roller 407 reaches the position of the calibration port 4078 after sequentially feeding through the plurality of groups of feeding ports 4073, the amount of the alumina powder is reduced, and the flow rate value monitored by the second flow rate monitor 4079 is reduced and is less than one fifth of the flow rate value monitored by the first flow rate monitor 4074, so that the inside of the crushing roller 402 is determined to be blocked.
In order to avoid further blockage of the alumina powder on the top of the subsequent conveying mechanism 3 caused by the alumina powder continuously entering the crushing roller 402 along the feeding hopper 401, the rotation speed of the second driving motor 301 is reduced, the flow rate of the alumina powder on the top of the feeding belt 304 entering the feeding hopper 401 is reduced, and the reduction is the flow rate difference value monitored by the second flow rate monitor 4079.
That is, after the first flow monitor 4074 monitors that the flow rate of the alumina powder in the feed hopper 401 is 10m/s under the initial condition and the average distribution of the four discharge ports 4073 and the calibration ports 4078 is performed, the flow rate monitored by the second flow monitor 4079 is 2m/s, after the inside of the pulverizing drum 402 is blocked, the flow rate monitored by the first flow monitor 4074 in the feed hopper 401 is still 10m/s, but the flow rate monitored by the second flow monitor 4079 is 1m/s, which indicates that the pulverizing drum 402 is blocked by 1m/s at this time, in order to ensure that the inside of the pulverizing drum 402 is not blocked further, the flow rate of the alumina powder falling on the feed hopper 401 along the feed belt 304 is reduced by adjusting the rotation speed of the second driving motor 301, and the flow rate monitored by the first flow monitor 4074 is 9m/s, thereby ensuring that the alumina powder entering the inside of the pulverizing drum 402 along the feed hopper 401 can be discharged by the pulverizing drum 402, and avoiding blocking caused by the pulverizing drum 402.
