Durable Electric Scraper-Type Self-Cleaning Filter

The durable electric scraper-type self-cleaning filter is mainly used to filter impurities in liquids and is widely used in chemical, petroleum, pharmaceutical, water treatment and other industries. It uses a high-precision filter screen, which can effectively remove tiny impurities in the liquid. The filter adopts a closed structure, which is free of leakage and pollution.

The durable electric scraper-type self-cleaning filter employs a scraper mechanism to scrape off impurities on the filter screen to achieve the purpose of filtration. Its working process is as follows:

1. The liquid to be treated enters the filter from the liquid inlet and is evenly distributed on the filter screen through the dispenser.

2. The filter screen traps the impurities in the liquid, and the clean liquid flows out through the pores of the filter screen and enters the liquid outlet.

3. As the filtration process progresses, the impurities on the filter screen gradually increase, resulting in an increase in filtration resistance. When the resistance reaches the set value, automatically or manually start the scraper device.

4. The scraper device reciprocates on the filter screen to scrape off the impurities on the filter screen, and the impurities move to the impurity collection area with the scraper.

5. When the scraper device returns, impurities are removed, the filter screen is restored to unobstructed, and the filtration resistance is reduced.

6. When the scraper device has been running for a certain period of time or times, it will automatically or manually stop and wait for the next cleaning.

Structural Features

The durable electric scraper-type self-cleaning filter is mainly composed of the following parts:

1. Filter screen: The filter screen is the core component of the scraper filter, usually made of stainless steel or other corrosion-resistant materials, with high strength and corrosion resistance. The pore size of the filter screen can be selected according to needs to meet the requirements of different filtration accuracy.

2. Scraper device: The scraper device is a key component to achieve filter cleaning, usually composed of a scraper, a scraper drive device, and a scraper guide rail. The material and shape design of the scraper should take into account good contact with the filter and effective scraping of impurities.

3. Dispenser: The dispenser is used to distribute the liquid to be treated evenly on the filter screen to ensure the filtration effect and prolong the service life of the filter screen.

4. Impurity collection area: The impurity collection area is used to collect impurities scraped by the scraper, and is usually equipped with a slag discharge port to facilitate discharge and cleaning.

5. Control system: The control system is used to control the start, stop, and running speed of the scraper device, and can be controlled automatically or manually.

Parameters

Key Benefits

1. Increased uptime. Continuous self-cleaning functionality eliminates the need for frequent shutdowns due to filter clogging, ensuring uninterrupted production and maximizing plant utilization.

2. Reduced maintenance. The automated cleaning process significantly reduces the frequency and intensity of manual interventions, lowering maintenance costs and minimizing operator exposure to potentially hazardous environments.

3. Energy efficiency. The targeted scraping action consumes relatively low energy compared to alternative cleaning methods, such as backwashing or reverse flow, which may require higher pressures and larger volumes of fluid.

4. Enhanced process reliability. Consistent filter performance and accurate filtration control contribute to improved product quality and process stability, reducing the risk of contamination-related issues and non-conformances.

Operational Maintenance

1. Installation. Install the device correctly according to the equipment manual and site conditions, ensuring proper connections for the inlet, outlet, and drain valve, leveling the device, and securely fixing its feet.

2. Commissioning. Conduct an unloaded test run before first use, checking whether all components operate normally and if control system parameters are set appropriately.

3. Runtime Monitoring. Regularly review device operation data, such as differential pressure, flow rate, motor current, promptly identifying and addressing any abnormalities.

4. Scheduled Maintenance. According to manufacturer recommendations, perform regular maintenance tasks like filter screen cleaning or replacement, scraper wear inspection, electrical component checks, etc.

5. Fault Handling. In case of device failure, promptly shut it down, and have it inspected by professionals; do not operate the equipment while faulty.

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.
