The vacuum filter belt is an industrial filtration equipment used for solid-liquid separation, and is widely used in chemical, mining, food processing, environmental protection and other fields. Effective maintenance of the vacuum filter belt can greatly increase the service life of the vacuum filter belt.

Daily maintenance:

Cleaning work.

After work every day, clean the vacuum filter belt thoroughly to prevent residual materials from clogging the pores of the filter cloth.

Select acid-base neutral cleaning agents according to the composition of the filtered material.

Inspect and clean the vacuum box and drainage pipe of the vacuum filter belt.

Filter cloth inspection.

Check whether the filter cloth is damaged, torn or excessively worn.

Observe whether the air permeability of the filter cloth decreases (manifested by a significant slowdown in filtration speed).

Check whether the seams of the filter cloth are firm.

Operation monitoring.

Record changes in vacuum degree (abnormal increase may indicate clogging of the filter cloth).

Monitor changes in moisture content and thickness of the filter cake

Check whether the belt speed of the vacuum filter belt is stable

Regular maintenance:

Lubrication system.

Lubricate the drive roller and tension roller bearings of the vacuum filter belt every month.

Check the lubricating oil level of the reducer and replace it regularly.

Lubricate the slide rails and bearings of the correction system.

Comprehensive inspection.

Check the wear of the vacuum box seal strip every quarter.

Check the parallelism and horizontality of all rollers.

Calibrate the sensitivity of the correction device.

Filter cloth replacement.

Replace the filter cloth regularly according to the usage (usually 3-12 months).

When replacing, pay attention to choosing the filter cloth of the same specification.

Pre-coat the new filter cloth before use.

Seasonal maintenance:

Long-term shutdown maintenance.

Thoroughly clean the entire system.

Remove the filter cloth and clean it Dry and store after washing.

Drain the liquid in the pipe to prevent freezing or corrosion.

Apply anti-rust oil to metal parts.

Re-activate and check.

Check the insulation performance of all electrical systems.

Test the flexibility of each moving part.

Gradually increase the operating load to avoid sudden full-load operation.

Treating common problems:

Clogged filter cloth.

Immerse and clean with special cleaning agent.

Backwash the filter cloth.

Consider using ultrasonic cleaning equipment.

Deviation problem.

Adjust the deviation correction device.

Check the parallelism of the rollers.

Confirm that the tension is uniform.

Lower vacuum degree.

Check the working status of the vacuum pump.

Check whether the pipes and joints are leaking.

Confirm that the vacuum box is well sealed.

Maintenance records:

It is recommended to establish detailed maintenance records, including:

Filter cloth replacement date and hours of use.

Lubrication time and type of lubricant used.

Problems and solutions.

Spare parts replacement records.

Through systematic maintenance, the vacuum filter belt can be kept in the best working condition, production efficiency can be improved and maintenance costs can be reduced.
