High Efficiency Scraper Self-Cleaning Filter

The high efficiency scraper self-cleaning filter serves as an kind of advanced water treatment equipment. It adopts a unique design and working principle to automatically remove impurities from liquids and ensure fluid cleanliness. This filter is widely used in various industrial circulating water systems and plays an important role in protecting equipment, prolonging equipment life, and improving production efficiency.

 

Structural Features

The high efficiency scraper self-cleaning filter is mainly composed of filter screen, scraper device, sewage outlet, inlet and outlet pipeline and other parts.

1. Filter screen

The filter screen is the core component of the scraper self-cleaning filter, usually made of stainless steel or other corrosion-resistant materials. The filter screen has a certain pore size to block solid particles and impurities in the liquid, while allowing clean liquids to pass through.

2. Scraper device

The scraper device is located above or on the side of the filter screen and is a key part of the automatic cleaning mechanism. The scraper is usually composed of a curved scraper blade or blade that can be moved along the surface of the filter screen. When a certain amount of solid particles and impurities have accumulated on the surface area of the filter screen, the scraper device will start to scrape off the accumulation on the filter screen.

3. Sewage outlet

The solid particles and impurities scraped by the scraper are pushed towards the sewage outlet of the filter. The sewage outlet is usually located at the bottom or side of the filter to facilitate the discharge and treatment of accumulation.

4. Inlet and outlet pipelines

The inlet pipeline is used to introduce the liquid to be treated into the filter, while the outlet pipeline is used to discharge the filtered cleaning liquid.

 

How It Works

During the working process, the liquid to be treated enters the filter through the inlet pipe, and after being filtered by the filter screen, the clean liquid flows out through the outlet pipe. As the filtration process progresses, a certain amount of solid particles and impurities will accumulate on the surface of the filter screen. When the accumulation reaches a certain level, the scraper device will automatically start, scrape off the accumulation on the filter screen, and discharge it through the sewage outlet. The whole process does not require manual intervention, realizing automated and continuous filtration operations.

Advantages

1. Automatic cleaning. The high efficiency scraper self-cleaning filter has the characteristics of automatic cleaning, and the filter can be cleaned and slag discharged without manual intervention. This greatly reduces maintenance costs and labor costs, and improves production efficiency.

2. High-efficiency filtration. The filter is cleaned with a scraper to ensure high-efficiency filtration performance for a long time. At the same time, the filter aperture can be adjusted to meet the filtration requirements of different applications.

3. Corrosion resistance. Since the scraper self-cleaning filter is usually made of stainless steel or corrosion-resistant materials, it has strong corrosion resistance and is suitable for a variety of liquid types.

4. Maintainability. The structure of the scraper self-cleaning filter is relatively simple, making it easy to maintain and clean. When it is necessary to replace the filter screen or perform other maintenance, the operation is simple and quick.

5. Save energy. Due to its efficient filtration and cleaning mechanism, the scraper self-cleaning filter consumes less energy during operation, which helps to reduce production costs.

 

Application Field

The high efficiency scraper self-cleaning filters are widely used in the following industries:

1. Water treatment

4. Pharmaceutical

In the pharmaceutical process, a scraper self-cleaning filter can filter microorganisms, bacteria, and other impurities in the liquid medicine to ensure the quality and safety of the medicine.

 

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.
