Industrial Horizontal Automatic Self-Cleaning Screen Filter

The industrial horizontal automatic self-cleaning screen filter can not only effectively remove suspended solids and particulate impurities in water and ensure clean water quality, but also greatly reduce the maintenance burden and achieve continuous and uninterrupted water purification through its unique design and intelligent operating system.

 

Structure composition

The structural design of the industrial horizontal automatic self-cleaning screen filter revolves around its high-efficiency filtration and automatic cleaning functions, including the following key components:

1. Housing

Usually made of stainless steel or carbon steel to ensure the corrosion resistance and durability of the equipment. The inside of the housing is a filter cavity, and the outside is equipped with a water inlet and outlet and a control panel.

2. Filter screen components

The filter screen is the core of filtration. According to application requirements, filter screen of different materials (such as stainless steel, nylon) and pore sizes can be selected to meet different filtration accuracy requirements.

3. Cleaning mechanism

including rotating brush, nozzle, drive motor, etc., responsible for the automatic cleaning of the filter screen.

4. Control System

Contains electronic components such as sensors, controllers, and timers, which are responsible for monitoring the filtration status, triggering cleaning procedures, and controlling the cleaning process.

5. Sewage system

Collect impurities that fall off during cleaning and discharge them to the designated location through the sewage valve.

 

Working principle

The core of the industrial horizontal automatic self-cleaning screen filter lies in its automatic cleaning mechanism, which ensures that the equipment can maintain itself while continuously running without frequent manual intervention. Specifically, its workflow includes the following steps:

1. Water inlet and filtration

The water flow first enters the filter through the water inlet, and then flows through the precision filter screen. At this stage, impurities and suspended solids in the water are trapped on the filter screen, while the clean water passes smoothly and flows to the next treatment step or direct use.

2. Differential pressure or time monitoring

The built-in sensor of the device continuously monitors the difference in water pressure before and after the filter (pressure difference) or according to the preset time interval, which is the key to determine when to start the cleaning program. Generally speaking, when the pressure difference reaches a certain threshold or reaches the preset cleaning time, the cleaning program will automatically activate.

3. Cleaning trigger

After the cleaning conditions are reached, the control system will instruct the cleaning mechanism to start working. This may involve rotating the filter screen, opening the nozzle to flush or backwashing, depending on the design of the equipment.

4. Cleaning process

In the cleaning mode, some or all of the filter units will temporarily stop filtering and clean themselves instead. For the rotary brush type, the filter screen will rotate slowly, and the nozzle will spray high-pressure water or air flow, which directly acts on the surface of the filter screen to wash away the attached impurities. For the backwash type, by changing the direction of the water flow, the impact force of the water flow will be used to peel the impurities from the surface of the filter screen, and then discharge them out of the system through the sewage outlet.

5. Restore filtration

After cleaning, the system automatically returns to the normal filtration state and continues the water treatment operation. The entire process requires no manual intervention, achieving a continuous and efficient filtration operation.

Application field

The industrial horizontal automatic self-cleaning screen filters are widely used in many industries and fields due to their high efficiency and flexibility.

1. Industrial circulating water system

Such as power, chemical, steel, paper and other industries, used to protect cooling towers, heat exchangers and other equipment from impurities in water.

2. Cooling water treatment

Ensure the efficient and stable operation of cooling systems in air conditioners, data centers, and other facilities, and reduce energy waste caused by dirt blockage.

3. Reverse osmosis pretreatment

In applications such as seawater desalination and wastewater reuse, it is used as a pretreatment step before RO membranes to remove large particles of impurities and protect membrane components.

4. Agricultural irrigation

Provide clean water for modern agricultural irrigation systems such as drip irrigation and sprinkler irrigation, prevent clogging of sprinklers, and improve irrigation efficiency.

5. Drinking water treatment

Before the raw water enters the finer treatment, it is used as a preliminary filtration to remove large particles of impurities and ensure the stable operation of the subsequent treatment unit.

 

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.
