Straight-Through Basket Filter Strainer

The structure of the straight-through basket filter strainer makes the fluid inlet and outlet on the same level, so that the design is convenient to install directly in the process pipeline to realize the continuous passage of fluid. When the fluid enters the filter from the inlet, it first passes through the outside of the filter basket, and then penetrates into the inside of the filter basket through tiny gaps or mesh holes in the filter basket wall. During this process, solid impurities are trapped on the surface or inside of the filter basket due to their size larger than the aperture of the filter screen, and the clean fluid passes through the filter screen smoothly and is discharged from the outlet, so as to achieve the purpose of separating impurities and purifying the fluid.

Over time, the accumulation of solid impurities in the filter basket will gradually increase, causing the pressure difference to increase and affecting the filtration efficiency. At this time, the filter needs to be maintained. The maintenance process usually includes: closing the relevant valve to isolate the filter; opening the bottom drain valve to drain the fluid inside the filter; removing the filter flange and removing the filter basket; thoroughly cleaning or replacing the filter basket to remove the attached impurities; finally, reassembling and opening the valve to restore the normal operation of the filter.

Structural features

1. Modular design

The straight-through basket filter strainer adopts a modular design, mainly composed of a shell, a filter basket, seals, flange connectors and discharge devices. This design is not only convenient for on-site installation and maintenance, but also allows users to flexibly choose the material, aperture size and filtration grade of the filter basket according to actual needs to adapt to different working conditions.

2. Material diversity

In order to adapt to the chemical properties and operating temperatures of different media, the shell and filter basket of the straight-through basket filter strainer can be made of a variety of materials, including but not limited to carbon steel, stainless steel, titanium alloy, etc. These materials have good corrosion resistance and mechanical strength, ensuring long-term stable operation of the filter.

3. Easy to maintain

The maintenance of the straight-through basket filter strainer is simple and fast, and the removal, cleaning or replacement of the filter basket can be completed without professional tools, which greatly reduces maintenance costs and downtime. In addition, some designs are also equipped with quick-opening blind plates or quick-opening top covers, further simplifying the maintenance process.

Parameters

Scope of application

The straight-through basket filter strainer is widely used in various industrial fluid handling systems due to their efficient and reliable filtration performance.

- Chemical industry. Used for raw material pretreatment, reaction medium filtration, to protect pumps, valves and reactors from solid impurities.

- Oil and gas. Removes solid particles from water and oil mixtures in transmission pipelines to protect pumps and instrumentation equipment.

- Food and Beverage. Ensure product purity, remove foreign matter in water, juice, beer and other fluids, and meet food safety standards.

- Pharmaceutical industry. During the drug preparation process, the raw material liquid and solvent are finely filtered to ensure the quality of the drug.

- Water treatment. Municipal and industrial water pretreatment to remove suspended solids and protect subsequent RO membranes, ultrafiltration membranes and other precision equipment.

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.
