III. Quick-Open Basket Filter Mechanical Operation and Maintenance Manual
3.1 Overview of Quick-Open Mechanism
The quick-open filter, due to its reasonable structure, meticulous manufacturing, and strict quality control, ensures safe and reliable use. However, improper installation and operation may still cause damage to the filter.
Operators must correctly assess the potential environmental impact of filter failure and implement corresponding preventive measures to ensure safe operation of this product.
The filter must be used correctly and safely. Adhere to labor safety protection and accident prevention regulations, especially those concerning technical working media (GSG) and pressure vessel regulations. General safety, usage, and maintenance regulations or requirements are detailed on subsequent pages.
DANGER: NEVER open the filter top cover before the filter inlet/outlet valves are closed AND the drain valve is vented!
The quick-open multi-bag filter allows lid opening/closing operations to be completed in less than 30 seconds. This eases operator workload while reducing downtime, maintenance costs, and delivering practical economic benefits.
3.2 Filter Commissioning
Refer to the following steps before installing the filter basket and starting operation:
- Lift the safety lock handle and rotate the lid locking wheel counterclockwise.
- Once all lid clamps are fully released, lift the lid handle to swing the top cover upwards. When replacing the basket, swing the cover to its maximum position.
- Place the filter basket into the filter housing. The seal ring must be checked for damage and correct seating.
- Ensure the basket neck sits flat. Place the compression ring (clamping ring) on top. The compression ring can be easily rotated and locked using a special tool. The handle on the compression ring MUST be rotated into the positioning notch; otherwise, there is a risk of the ring loosening.
- Before lowering the top cover, inspect the sealing surfaces and seal ring for [damage and cleanliness. Keeping the V-flange and clamp locking device clean is crucial]. Replace damaged seal rings promptly! Ensure the seal ring is correctly positioned.
- The procedure for locking the compression ring is the reverse of opening.
- After installing the basket, swing the lid back down, rotate the lid locking wheel clockwise, and pull down the safety lock handle to lock it. The filter is now ready for use.
- Slowly open the inlet pipe valve. Caution: Do not open too quickly to prevent sudden pressure surges from rupturing the basket or damaging other components. Ensure the vent valve is open to purge air from the filter. Close the vent valve immediately once liquid flows out. Operators must take safety precautions when filtering hazardous liquids to avoid contact (often connect a bent tube to the vent valve for drainage).
- If residual air remains trapped inside the filter, it may affect filtration efficiency; therefore, vent periodically.
- Now slowly open the outlet valve (to put into operation).
3.3 Filter Maintenance
Normally, the filter requires no special maintenance. However, for equipment equipped with the quick-opening clamp, proper maintenance of the seal system is crucial for long-term leak-free operation. After each lid opening, the sealing surfaces and O-ring groove MUST be thoroughly cleaned using pressurized water jets before re-closing the lid. This prevents foreign particles (e.g., solid debris, plant fibers, powder) from remaining in the sealing area, which could compromise seal integrity and cause leaks during operation. All components should be regularly inspected for corrosion and other damage. Basket replacement depends on clogging status and changes in the filtered medium. Clogging is determined by the pressure differential across the filter inlet/outlet.
- Pump Suction (Pre-filter) Use: We recommend replacement at a differential pressure of 0.15 bar (maximum up to 1.2 bar). Otherwise, there is a risk of basket rupture. Before replacing the basket, the vent valve MUST be opened to depressurize the filter. The remaining operational steps are identical to Section 3.2 "Commissioning".
Declaration: Although seal rings are often reused in practice, our company supports the seal ring supplier's recommendation that the seal ring should be replaced every time the filter is opened. Seal ring failure does not indicate a defect in the filter.
3.4 Lid Locking Mechanism Maintenance
- The lid balancer should operate precisely and be adjustable, allowing the lid to stay in any position. Adjust the tightness of the bolt below the balancer so the lid stays in any position.
Safety Precautions:
- The lid balancer must not contact corrosive substances.
- Although the lid can stay in any position, do not leave it in a half-open state.
- When replacing the basket, open the lid to its maximum safe position.
- If lid removal is necessary, the lid must be opened to its maximum safe position.
- WHEN OPENING THE LID TO REPLACE/CLEAN THE BASKET, THE INLET AND OUTLET MANUAL KNIFE GATE VALVES OF THE FILTER MUST BE CLOSED. THIS IS VERY IMPORTANT FOR SAFE OPERATION!!!
