Internal Scraper Self-Cleaning Filter

Name: Internal Scraper Self-Cleaning Filter
Brand: AIDA
SKU: 236816362

The internal scraper self-cleaning filter integrates filtration, cleaning, sewage discharge and other functions. It has the advantages of automatic control, stable operation and easy maintenance.

Product Details

The internal scraper self-cleaning filter is mainly composed of a cylinder body, a filter screen, a scraper, a driving device, a sewage valve and other parts. The cylinder body is the main bearing component of the filter, and is usually made of carbon steel, stainless steel and other materials. The filter screen is the core part of the filter medium. Filters with different precision can be selected according to needs to meet the filtration requirements of different working conditions. The scraper is a key component to realize the self-cleaning function. Its shape and size design should match the filter screen to ensure the cleaning effect. The driving device includes a motor, a reducer, etc., which is responsible for providing power for the scraper. The sewage valve is used to discharge the dirt generated during the cleaning process and is usually arranged at the bottom of the cylinder.

Working Principle

The working principle of the internal scraper self-cleaning filter is: the liquid to be treated enters from the inlet of the filter, and when it passes through the filter screen, the impurities are trapped on the filter screen, while the clean liquid flows out through the pores of the filter screen, thereby realizing solid-liquid separation. As the filtration process progresses, the impurities on the filter screen gradually increase, resulting in a decrease in the filtration efficiency of the filter screen. At this time, the driving device starts to drive the scraper to rotate on the inner wall of the filter screen. The scraper of the scraper is close to the surface of the filter screen, scraping off the impurities attached to the filter screen, and discharging them through the sewage valve. In this way, the filter screen can be kept clean and the filtration effect is guaranteed.

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.
