Preferably, the method comprises the following steps:

(1) After the power supply is started, the adjacent roller type crushers rotate oppositely to crush the workpiece to be processed;

(2) When foreign matters appear, the roller type crusher is stopped, and then the specific rollers automatically rotate reversely to enable all the rollers to be consistent with the direction of the materials, so that the foreign matters are discharged and enter the next procedure together with the crushed materials;

(3) After the foreign matters are discharged, the adjacent roller type crushers restore to rotate oppositely and normally operate;

(4) When the roller crusher continuously rotates reversely for many times, the operation of the roller crusher is immediately stopped.

Preferably, in the step (1), when no abnormal condition occurs, the adjacent roller crushers rotate in opposite directions, the adjacent roller crushers crush the material in opposite directions, and meanwhile, an operator can monitor the operation state of the roller crushers, the motor current and the bearing temperature on the control room operation platform.

Preferably, in the step (2), when the foreign matter is stuck between two adjacent roller crushers, the current of the motor will have a rapid rising trend, and the roller crushers will stop rotating when the current exceeds an extreme value; when the time t1 set by the program is reached, the roller crusher automatically rotates reversely, so that all rollers are consistent with the direction of the material; the foreign matters are conveyed from the shaft to the side edge of the roller crusher through the roller teeth and discharged, and the foreign matters and the crushed materials enter the next procedure.

Preferably, in the step (3), after the time t2 set in the program, the roller crusher is stopped again, and after the time t1 set in the program, the opposite rotation is resumed again, and the normal operation is performed.

Preferably, in the step (4), the DCS control system needs to monitor the number of paired gyrations of the roller crusher, and if the number of reversals exceeds n within the time t3 set in the program, the roller crusher is immediately stopped, and a manual work is needed to check the field condition of the equipment to make a problem judgment, so as to better protect the roller crusher.

Has the advantages that: the starting and stopping times of the roller crusher are reduced, and the energy consumption is reduced; the roller crusher can automatically discharge foreign matters, so that the waste of manpower is reduced; in addition, foreign matters can be discharged in time, the damage to the surface of the roller sleeve of the roller crusher is reduced, the yield of materials is improved, and the overall production level is improved.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1 is further illustrated with reference to fig. 1-2.

The control system of the roller crusher comprises the following specific steps:

step (1), after a power supply is started, when no abnormal condition occurs, the adjacent roller type crushers rotate oppositely, the adjacent roller type crushers crush materials in the opposite rotating process, and meanwhile, an operator can monitor the running state, the motor current and the bearing temperature of the roller type crushers on a control room operation platform;

through the monitoring of the operator, the operator can check the running condition of the roller crusher at any time, thereby avoiding the occurrence of emergency and improving the safety factor of the running of the equipment.

Step (2), when foreign matters are clamped between two adjacent roller crushers, the current of the motor can rapidly rise, and the roller crushers can stop rotating when the current exceeds an extreme value; when the time t1 set by the program is reached, the roller crusher automatically rotates reversely, so that all rollers are consistent with the direction of the material; the foreign matters are conveyed from the shaft to the side edge of the roller crusher through the roller teeth and discharged, and the foreign matters and crushed materials enter the next procedure;

when foreign matters appear, compared with the method that equipment needs to be stopped to take out the foreign matters manually in the prior art, the method for automatically and timely discharging the foreign matters by the roller type crusher reduces the starting and stopping times of the roller type crusher, reduces energy consumption, reduces the waste of manpower, improves the yield of materials, improves the production efficiency of enterprises and improves the overall production level.

And (3) after the time t2 set in the program, stopping the roller crusher again, and after the time t1 set in the program, restoring the opposite rotation again and normally operating.

After the foreign matter discharges, wait for the time t2 of setting for, the system monitoring does not have the foreign matter to disturb in t2 time and deems the foreign matter and has discharged completely, will resume again after the time t1 of setting for in the procedure again afterwards and rotate in opposite directions, normal operating, at this in-process, guaranteed that the roll crusher can in time carry out the crushing work to the material again after monitoring does not have the foreign matter to disturb, improved work efficiency.
