Self-Cleaning Scraper-Type Filter

In modern industrial production, the purification treatment of fluids is one of the key links to ensure product quality and stable operation of production lines. Especially when dealing with high viscosity liquids such as adhesives, resins, polymer solutions and oils, traditional filtration technology often faces the challenges of fast clogging, high maintenance costs and low efficiency.

 

The self-cleaning scraper-type filter, with its unique design and efficient working principle, provides a revolutionary solution to this problem.

 

The self-cleaning scraper-type filter is an efficient filtration equipment that uses mechanical scraping to automatically remove particulate impurities from the inner surface of the filter element, achieving continuous online filtration. Its main characteristic is that it is suitable for high viscosity filtration, which can effectively filter materials with a viscosity of up to 800,000 cps, with an accuracy range of 30-1500 microns. The scraper type self-cleaning filter is widely used in water treatment, chemical industry, food and other industries due to its high performance, high quality and high reliability.

 

Features of self-cleaning scraper-type filter

1. High-efficiency filtration

The self-cleaning scraper-type filter can quickly scrape impurities off the surface of the filter element, achieving efficient removal of more impurities and ensuring the filtration effect.

2. Suitable for high-viscosity materials

The self-cleaning scraper-type filter is specially designed for high-viscosity filtration, which can effectively filter materials with a viscosity of up to 800,000 cps to meet the filtration needs of special industries.

3. Wide range of accuracy

The accuracy range of the self-cleaning scraper-type filter is between 30 and 1500 microns, which can meet the filtration requirements of different particle sizes.

4. Reduce material waste

The self-cleaning scraper-type filter can regularly keep the filter element clean, effectively reducing material waste and improving material utilization.

5. Save investment and labor costs

Compared with traditional filters, self-cleaning scraper-type filters do not require frequent manual cleaning, reducing labor costs and equipment investment.

6. Suitable for a variety of media

Self-cleaning scraper-type filters are suitable for filtering viscous materials such as water, adhesives, resins, polymers, and oils with poor water quality, and have a wide range of applications.

 

Working principle of self-cleaning scraper-type filter

The self-cleaning scraper type filter is mainly composed of filter body, filter element, drive device and control system. Its working principle is as follows:

1. Filtration stage

The material enters the filter body through the feed pipe. Under the filtration action of the filter element, the particulate impurities are intercepted on the surface of the filter element, and the clean material flows out through the filter element.

2. Cleaning stage

The drive device starts, the scraper moves along the surface of the filter element, scrapes off the particles and impurities accumulated on the surface of the filter element, and then discharges them through the drainage pipe.

3. Automatic control

The filter and cleaning process can be automatically adjusted by the control system to achieve continuous online filtration.

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.
