Powerful Electric Scraper Self-Cleaning Filter

Our Powerful Electric Scraper Self-Cleaning Filter is an efficient and automated solid-liquid separation device widely used in various liquid filtration scenarios in industrial production processes. It ingeniously combines filtration, cleaning, and waste discharge functions, utilizing an electrically driven scraper mechanism to automatically remove impurities from the filter screen surface, ensuring the continuous stable operation of the filtration system.

Specification

Working Principle

The operation of a powerful electric scraper self-cleaning filter involves four key stages: filtration, monitoring, cleaning, and waste discharge.

1. Filtration - Untreated liquid enters the device through the inlet, flowing through the filter screen. The pore size of the filter screen is set according to actual requirements, effectively trapping suspended particles, colloids, microorganisms, and other impurities larger than the pore size, while clean liquid passes through the filter screen and exits through the outlet, completing the preliminary filtration process.

2. Monitoring - The device is equipped with an internal differential pressure sensor or timer, continuously monitoring the pressure differential across the filter screen or the operating time during filtration. When the pressure differential reaches a preset value (indicating a significant accumulation of impurities on the filter screen, resulting in increased resistance), or the operating time reaches a set value (for periodic cleaning), the cleaning program is triggered.

3. Cleaning - Upon initiation of the cleaning program, the electric motor drives the scraper mechanism into action. The scraper moves back and forth along the filter screen surface, scraping off impurities adhered to it.

4. Waste Discharge - Scraped-off impurities are discharged from the device along with the cleaning wastewater through the drain valve, completing one cleaning cycle. After cleaning, the filter resumes its initial filtration state, awaiting the next filtration cycle.

Structural Components

The powerful electric scraper self-cleaning filter primarily consists of the following key components:

1. Housing - Typically made of stainless steel, offering high strength and corrosion resistance, ensuring long-term stable operation of the equipment.

2. Filter Screen - The core filtering element, available in various materials and precision levels, such as metal wire mesh, sintered mesh, and fiber felt, to suit different operating conditions and filtration requirements.

3. Scraper Mechanism - Includes an electric motor, transmission device, and scraper assembly. The electric motor drives the transmission device, causing the scraper to move linearly or rotate along the filter screen surface, removing impurities.

4. Control System - Consists of a differential pressure sensor, timer, control panel, etc., responsible for monitoring the filtration status, triggering and controlling the cleaning process.

5. Inlet & Outlet, Drain Valve - Respectively used for connecting the pipeline for untreated liquid supply and filtered clean liquid discharge, as well as for discharging cleaning wastewater.

6. Seals - Ensure sealing between internal components of the device, preventing liquid leakage.

Main Features

1. High Automation - Through differential pressure or time-based control, the automatic cleaning program is initiated without manual intervention, reducing labor intensity and improving work efficiency.

2. Continuous Operation - During cleaning, the filtration system remains operational, without interrupting the overall process flow, enabling continuous, uninterrupted filtration.

3. Effective Cleaning - The scraper directly acts on the filter screen surface, efficiently removing both hard and soft impurities, preventing clogging and maintaining filtration efficiency.

4. Low Energy Consumption - Compared to backwash or suction-type self-cleaning filters, the electric scraper blade filter consumes less energy, resulting in a more economical operating cost.

5. Ease of Maintenance - With a compact structure and few wear parts, maintenance requirements are minimal, and some devices even support online filter screen replacement without requiring shutdown.

Application Areas

The Powerful Electric Scraper Self-Cleaning Filter, due to its efficiency and automation, is widely employed in liquid filtration processes across various industries:

1. Industrial Water Treatment - Such as circulating cooling water, process water, wastewater treatment, removing suspended solids, particulates, algae, etc.

2. Petroleum & Petrochemicals - In crude oil extraction, refining, transportation, and other stages, pre-treating petroleum products, removing sand, iron filings, gums, etc.

3. Metallurgy & Mining - Filtering slurry, acidic and alkaline solutions, electroplating baths, protecting production equipment and enhancing product quality.

4. Food & Beverages - Filtering raw water, processing water, beverage products, ensuring food safety and enhancing taste.

5. Pharmaceuticals & Biotechnology - Filtering pharmaceutical solutions, fermentation liquids, purified water, meeting GMP requirements, and safeguarding drug quality.

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.
