Russian Working Principle of Automatic Deviation Correction Device of Vacuum Belt Filter
The automatic deviation correction device of the vacuum belt filter is a key component of the equipment. It is mainly used to ensure that the filter belt remains stable during operation and prevents deviation, thereby improving filtration efficiency and reducing equipment loss. The following is a detailed introduction to the automatic deviation correction device.
Working principle of Automatic Deviation Correction Device
When the belt of the vacuum filter is running, some factors cause the tension on both sides of the vacuum belt to be uneven. The tension on the A side is less than the tension on the B side (dividing the two sides of the belt into A and B), and the belt begins to deviate to the A-side. When the belt deviates to the set range limit, the A sensor on the belt deviation range control part receives the deviation signal and inputs the belt deviation signal into the electrical control part. The electrical control part responds quickly and starts the motor. The motor passes through the reducer to reduce the speed and increase the torque. Then the force is transmitted to the actuator through the matching gear. The actuator begins to increase the tension of the belt on the side with less belt tension, and the tension on the A side of the belt continues to increase, thereby realizing belt deviation correction.
When the motor of the belt filter runs for a set time, the motor stops rotating. After another set time, if the tension on belt side A is greater than the tension on belt side B, the belt slowly moves to the B side; if the tension on belt side A is still slightly less than the tension on the belt side B, the A sensor on the belt deviation range control part detects the belt deviation signal again, and the belt deviation signal is input into the electrical control part again, and the electrical control part responds quickly and starts to increase the belt tension on the A-side. This cycle of control continues.
If the belt deviates to the B side, when the belt deviates to the set range limit, the B sensor on the belt deviation range control part receives the deviation signal and inputs the belt deviation signal into the electrical control part. The electrical control part responds quickly and the tension on the B side of the belt increases continuously to achieve the effect of deviation correction.
By continuously adjusting the tension on both sides of the belt, the tension on both sides is constantly balanced, and ultimately through this cyclic control, the normal operation of the belt is guaranteed.
The Role of the Automatic Deviation Correction Device
During the operation of the vacuum belt filter, the filter belt is subjected to uneven force for a long time or is affected by external factors (such as uneven material distribution, deflection of the drum axis, etc.), which is prone to deviation. Once the filter belt deviates from the normal operating track, the following problems may occur.
- The filter belt wears more and shortens its service life;
- The filtration effect is reduced and the solid-liquid separation efficiency decreases;
- The risk of equipment failure increases, which may lead to downtime for maintenance;
- Energy consumption increases, affecting production efficiency.
The automatic deviation correction device can monitor the position of the filter belt in real time, and by adjusting the guide mechanism, the filter belt is always kept on the correct track, thereby ensuring the long-term stable operation of the equipment.
Conclusion
The automatic deviation correction device of the vacuum belt filter plays a vital role in stabilizing equipment operation, reducing filter belt loss and improving filtration efficiency. Correct operation of the vacuum belt filter and daily maintenance can effectively extend the life of the equipment and improve production efficiency.
