Straight-Through Flow Basket Filter

The straight-through flow basket filter is a filtration device used in liquid piping systems. It is designed to remove impurities from the liquid and protect downstream equipment from particulate matter, thus ensuring stable operation of the system and improving product quality.

 

This type of filter is named after its structural characteristics, the main features include:

1. Straight-through design. This implies that the liquid enters one end of the filter, passes through the filtering basket, and flows out from the other end, forming a linear path. This design helps minimize pressure loss during liquid passage.

2. Basket structure. The filtering element typically consists of a removable, basket-shaped mesh screen. This basket holds a filter mesh with varying pore sizes, capable of trapping particles of different sizes. The basket design facilitates easy cleaning and replacement of the filter screen.

3. High flow capacity. Due to its spacious interior, the straight-through flow basket filter is well-suited for industrial applications requiring high-volume processing, such as in the chemical, petrochemical, water treatment, and food processing industries.

4. Multiple filtration ratings. Depending on specific application needs, basket filters with different mesh sizes can be selected, ranging from coarse to fine filtration, to meet varying liquid cleanliness requirements.

5. Durable construction. Typically made from stainless steel or other corrosion-resistant materials, the straight-through flow basket filter can withstand high working pressures and temperatures, ensuring long-term, reliable operation.

6. Ease of inspection and maintenance. Given its design, users can easily open the basket filter to inspect the clogging status of the filter mesh and perform cleaning or replacement, reducing downtime and maintenance costs.

Precautions for the selection and use of basket filters

1. When selecting a basket filter, consider the following factors:

- liquid properties. Including liquid type, temperature, pressure, and chemical compatibility.

- Particle size. Choose the appropriate filter aperture according to the size of the particles to be removed.

- Flow requirements. Select the filter of the corresponding specification according to the flow rate of the liquid to meet the requirements of the system.

- Cleaning frequency. Considering the maintenance and cleaning frequency of the equipment, choose a filter design that is easy to operate.

2. When using a basket filter, the following points need to be taken into account:

- Periodic inspection. Regularly check the pressure difference and flow rate of the filter to determine whether the filter basket needs to be cleaned or replaced.

- Cleaning method. When cleaning the filter basket, you can choose a suitable method, such as backwashing, brushing, or ultrasonic cleaning.

- Replace the filter basket. If the filter basket is damaged or cannot be restored after cleaning, a new filter basket should be replaced.

- Maintenance records. Keeping records of filter maintenance and cleaning helps predict future maintenance needs and optimize operations.

 

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
