Basket filter pipeline pre solid impurity interception and filtration equipment

Product basic parameters and core structure

1. nominal diameter: The basket filter covers DN25~DN700 and can be matched with pipes of different diameters, suitable for various types of pipeline engineering selection.

2. Working temperature: Applicable range -30 ℃~200 ℃, taking into account both low-temperature cold water and high-temperature heat transfer oil and steam medium working conditions.

3. Filtration accuracy: The filter mesh size ranges from 10 mesh to 300 mesh, and the filter basket can be freely selected according to the size of impurity particles.

4. Working pressure: Standard pressure levels are 1.0MPa and 1.6MPa, and higher pressure resistant shells can also be customized as needed.

5. Sealing material: Optional nitrile rubber, fluororubber, oil resistant asbestos gasket, suitable for water, oil, and weakly corrosive chemical media.

6. Main material: The shell can be made of carbon steel, 201 stainless steel, 304 stainless steel, or 316 stainless steel, suitable for ordinary water bodies, oil products, and acid-base media.

7. Core structure: composed of a cylinder, flange end cover, quick opening lifting ring, built-in filter basket, inlet and outlet flanges, and sewage interface. The filter basket is a cylindrical porous support structure with an externally welded metal filter screen, which has high overall strength and is not easily deformed by fluid impact.

8. Operating principle: The medium flows into the filter cylinder along the pipeline, and the liquid enters the interior of the filter basket downwards. Solid particles, rust, and sediment larger than the filter aperture are trapped in the filter basket cavity. The clean fluid passes through the filter screen and flows out from the outlet, completing solid-liquid separation; After the accumulation of impurities causes an increase in pressure difference, stop the machine, open the cover, take out the filter basket, rinse and clean it, and then reuse it.

9. Connection method: Standard flange connection, easy to connect and install with pipelines, reliable sealing.

10. Factory inspection: Before leaving the factory, the product undergoes a hydrostatic pressure test, weld seam inspection, and is accompanied by a product certificate and drawings to meet the acceptance standards of the engineering project.

Applicable industries and equipment operating conditions of the product

2. Petrochemical industry: pre-treatment of oil transportation pipelines and chemical fluid pipelines, filtration of solid particles in media, and prevention of downstream pump and heat exchanger blockage and wear.

3. Heating and HVAC system: High temperature hot water, heat transfer oil pipeline, filter pipeline rust and impurities, ensure stable operation of heat exchange units and plate heat exchangers.

4. Sewage treatment project: pre-treatment of sewage inlet pipeline, interception of fibers, solid particles and debris, protection of subsequent membrane components and precision filters.

5. Food and pharmaceutical industry: Raw material fluid pipeline filtration, using 304/316 stainless steel material to meet the requirements of clean medium filtration.

There is a significant difference in positioning between basket filters and self-cleaning filters. Basket filters belong to offline periodic cleaning filters, with a simple structure and low procurement costs. They are suitable for pipelines with moderate impurity content and allow for short-term shutdown cleaning; The fully automatic self-cleaning filter is suitable for working conditions with high impurities and 24-hour continuous operation without stopping. The combination of the two can achieve multi-stage filtration protection for pipelines.

Core competitive advantages of the product

1. Easy disassembly and maintenance, low maintenance costs. The filter basket can be removed and cleaned as a whole, without the need to disassemble the entire pipeline. After cleaning, it can be directly reinstalled, making operation and maintenance simple without complex operations.

2. Large flow area and low pressure loss. The cylindrical filter basket structure has a large effective filtration area, low fluid resistance, and will not have a significant impact on pipeline flow.

3. Rich material selection and wide adaptability to various media. Carbon steel and multiple types of stainless steel shells are matched with various sealing gaskets, which can handle water, oil, weakly corrosive chemical media, and can be used in both high and low temperature conditions.

4. The structure is sturdy and the pressure resistance is reliable. The cylinder is formed by welding, with flange fastening and sealing, stable pressure performance, and strong resistance to fluid impact.

5. The accuracy is flexible and adjustable. The filter basket can be replaced as needed, with 10-300 mesh and multiple precision options, suitable for different particle interception needs.

6. Flexible installation method and small space occupation. It can be installed horizontally or vertically, and pipeline renovation projects can also be conveniently installed.

Source factory production advantage

1. Standardized manufacturing process, strict inspection and pressure testing. The welding process specification for the cylinder body requires water pressure testing for each product, ensuring safe and reliable pressure bearing of the shell.

2. Full specification spot stock reserve, fast delivery. Regular diameters from DN25 to DN700 are available in stock and can be quickly supplied for pipeline matching projects.

3. Customized service support. We can customize the shell material, filter basket accuracy, and quick opening structure according to the characteristics of the customer's medium, pressure and temperature. Special working conditions can also be treated with anti-corrosion lining.

4. Complete supporting facilities and one-stop supply. In addition to the complete filter, spare parts such as filter baskets and sealing gaskets can be provided for easy replacement in the later stage.

5. Complete installation guidance. The product comes with installation drawings, which can provide technical support for selection and guide on-site pipeline docking.

6. Strong project supporting capabilities, supporting bulk foreign trade orders. We can provide technical materials in both Chinese and English, standardized export packaging, and meet the needs of engineering procurement at home and abroad.

Frequently Asked Questions (FAQ)

Q1: What is the working principle of a basket filter?

A: The fluid medium enters the inner cavity of the filter cylinder, passes through the built-in metal filter basket, and solid particles, rust, and sediment are trapped inside the filter basket. Clean liquid flows out from the outlet through the filter screen. When impurities accumulate in the filter basket and the pressure difference between the inlet and outlet increases, stop the machine, open the upper cover, take out the filter basket, rinse and clean it, and then put it back into use to achieve solid-liquid pretreatment of the pipeline fluid.

Q2: Are basket filters suitable for continuous and uninterrupted production lines?

A: The basket filter requires a short-term shutdown for cleaning, which is suitable for pipelines that allow for short-term shutdown maintenance; If the process requires continuous operation throughout the year without shutdown, a dual basket structure with one in use and one backup can be selected, or a fully automatic self-cleaning filter can be replaced.

Q3: How often is the filter basket cleaned?

A: The cleaning cycle depends on the fluid impurity content. Clean circulating water is usually cleaned every 1-3 months; For media with high impurities such as sewage and oil, it is recommended to shorten the cleaning time to 2-4 weeks, and the cleaning timing can be determined based on changes in inlet and outlet pressure differences.

Q4: How to choose sealing components when the medium temperature is high?

A: It is recommended to use fluororubber or oil resistant asbestos sealing gaskets for high temperature conditions; Nitrile rubber gaskets are selected for normal temperature and clean water conditions, and the sealing material can be matched according to the temperature and corrosiveness of the medium.
