It is noted that the analysis processing module monitors the steering revolution number operated by the steering numerical control transmission module, and performs standard control guidance on the steering revolution number instruction modulus of the running bar 25 between each left and right adjacent ultrasonic vibrator 101, each standard control guidance corresponds to a group of adjacent ultrasonic vibrators 101 in the switch signal control transmission module, so when the running bar 25 reaches between the left and right adjacent ultrasonic vibrators 101, the analysis processing module sends the standard control guidance to the switch signal control transmission module, the switch signal control transmission module sends down to start the ultrasonic generator correspondingly connected with the two ultrasonic vibrators, the left and right adjacent ultrasonic vibrators 101 operate, when the running bar 25 leaves between the left and right adjacent ultrasonic vibrators 101, the standard control guidance is lost, and the next standard control guidance is obtained, and when the running bar 25 resets right, the analysis processing module does not send the standard control guidance to the switch signal control transmission module.
Referring to fig. 12, the crushing control module includes a powder concentration signal receiving module and a control signal receiving module, where the powder concentration receiving module is configured to receive, in real time, a powder concentration value uploaded by the powder concentration detecting head 102, where the powder concentration signal receiving module and the control signal receiving module are in transmission connection with an analysis processing module, where the analysis processing module is in transmission connection with a first rotational speed control module and a second rotational speed control module, where the analysis processing module is configured to receive control information issued by the industrial personal computer 52, and further configured to analyze the powder concentration value input in real time to control the first rotational speed control module and the second rotational speed control module to perform rotational speed control operation;
The first rotating speed control module is used for controlling the rotating speed of the first motor 12, a signal output pin of the first rotating speed control module is connected with a signal input end of the driver 53 of the first driving motor 12 through a signal wire, the second rotating speed control module is used for controlling the rotating speed of the third motor 39, and a signal output pin of the second rotating speed control module is connected with a signal input end of the driver 53 of the third driving motor 39 through a signal wire.
Setting the basic powder concentration as Eg/m 3, setting the basic rotating speed of the motor I12 as 1500r/min, setting the basic rotating speed of the motor III 39 as 2000r/min, and when the powder concentration F input in real time is more than or equal to E, controlling the motor I12 and the motor III 39 by the rotating speed control module I and the rotating speed control module II to keep the running speed unchanged, wherein the powder concentration F input in real time is less than 20g/m 3, increasing the rotating speed control module I by 50r/min on the original basic rotating speed control instruction, increasing the rotating speed control module II by 80r/min on the original basic rotating speed control instruction, wherein the upper instruction limit of the rotating speed control module I is 2000r/min, and the upper instruction limit of the rotating speed control module II is 2800r/min.
By accelerating motor one 12, the transverse swing speed of the screen plate 22 is increased, so that the screen action deblocking effect is improved, and by accelerating motor three 39, the rotation speed of the cyclone rod 44 and the stacking plate 45 is faster, and the powder blocks in baking soda powder are crushed more effectively.
The working principle of this embodiment is as follows:
the rotary rubbing mechanism can effectively crush and rub the baking soda powder in the lower row, so that the caking amount in the baking soda powder is reduced;
The ventilation mechanism is used for detecting ventilation of each row of meshes of the screen plate 22 and removing baking soda powder blocks stored in the meshes by blowing when the ventilation mechanism drives the travelling bars 25 to move on the screen plate 22;
The control mechanism judges the caking condition according to the concentration of the powder discharged by the rotary rubbing mechanism and controls the rotary vibrating mechanism and the rotary rubbing mechanism to operate and accelerate, thereby ensuring the treatment efficiency.
And the control mechanism and the ventilation mechanism are that after the flap valve 48 operates to close the valve and the powder discharge pipe 5 has no baking soda powder discharge, the industrial personal computer 52 gives an operation command, the motor II 28 drives the screw rod 29 to operate so that the traveling bar 25 moves and stops at the upper and lower positions of the screen plate 22 by taking the distance between two rows of meshes as the movement amount, the electromagnetic reversing valve 33 is controlled to reverse, the gas flow rate is detected first, then the powder block is blown off, in the process, the ultrasonic vibrator 101 is controlled to perform opening and closing operation according to the position of the traveling bar 25 until the powder block is completed, and the baking soda powder block in the meshes of the screen plate 22 can be separated quickly under the operation of the ultrasonic vibrator 101 with the dislocation of the front and rear positions, so that the powder block can be blown off quickly in a gas blowing mode.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
