Quotation for domestic dual filter

　　Overview of stainless steel bag type dual filter:

　　Dual filter, also known as parallel switching filter, is composed of two stainless steel filters connected in parallel, or multiple filters can be interconnected. Two three-way ball valves are used to assemble two single cylinder filters onto one machine base. When cleaning the filter, there is no need to stop it to ensure its continuous operation, which is the preferred choice for non-stop production line filtration devices. It has many advantages such as novel and reasonable structure, good sealing, strong flow capacity, and easy operation. A versatile filtering device with a wide range of applications and strong adaptability.

　　This filter can also be used as a single cylinder. In this case, only the common machine base needs to be removed, and the other dimensions remain unchanged.

　　This device can use filter bags or filter cartridges as filtering elements. In terms of functionality, it can be processed into one backup and one use model, which can be switched between use, but cannot be used simultaneously. It can also be processed to be interchangeable or used simultaneously.

　　Design pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.0Mpa, 2.5Mpa.

　　Surface treatment methods: mirror polishing, sandblasting, etc.

　　Import and export forms: flange, quick installation, thread.

Stainless steel bag type dual filterThe operation process:

preparation:

Ensure that all operators are familiar with the equipment operating procedures and safety measures.

Check if the equipment is in good condition, including inspecting the filter housing, pipeline connections, support structures, and valves.

Confirm that the filter medium (filter bag) has been pre installed in the filter cartridge as needed and is well sealed.

Check the system:

Check if all valves in the system are in the correct open or closed position.

Confirm that the liquid supply pump and motor are operating normally, without any abnormal noise or vibration.

Check if the pressure gauge and other instruments are working properly.

Start filtering:

Slowly open the feed valve and allow the liquid to be filtered to enter the filter.

Observe the pressure gauge reading to ensure that the working pressure does not exceed the bearing limit of the filter bag.

Monitor filtration efficiency and flow rate to ensure that filtration quality meets requirements.

Switching operation:

When the pressure difference of a filter cartridge reaches the preset value (usually indicating a clogged filter screen), stop feeding the filter cartridge.

Close the inlet and outlet valves of the filter cartridge, and open the exhaust valve to empty the liquid inside the filter cartridge.

Switch to another prepared filter cartridge to continue the filtering operation.

Cleaning and replacing filter bags:

Remove the filter bag that has reached the pressure difference limit, and be careful to avoid the leakage of pollutants.

Choose appropriate cleaning methods based on the degree of pollution, such as backwashing, chemical cleaning, or replacing the filter bag with a new one.

During the cleaning or replacement process, appropriate protective equipment should be worn to prevent contact with harmful substances.

Maintenance and upkeep:

Regularly check the sealing performance of the filter to prevent leakage.

Clean the filter housing and pipes to keep the equipment clean.

Record operational data and maintenance status for tracking equipment performance and predicting maintenance needs.

Notes:

Before and after operation, ensure that personal protective equipment is complete, especially when handling hazardous chemicals.

During the operation, attention should be paid to observing the operation status of the equipment. If any abnormalities are found, the machine should be stopped immediately for inspection.

Comply with environmental protection regulations and properly dispose of waste generated from filtration.

Shutdown and Storage:

After completing the filtering task, close all valves and stop the pump.

Clean the surface of the equipment and remove any residue.

If not used for a long time, the inside of the filter should be dried and covered with a protective cover to prevent dust.
