High Efficiency Vertical Type Auto Backwash Filter

The high efficiency vertical type auto backwash filter is a device designed for use in water treatment and other liquid filtration applications. It is characterized by the ability to automatically backwash to remove intercepted impurities, thus ensuring continuous filtration efficiency and extending filter life. The equipment is installed vertically, saving space and suitable for various installation environments, especially where space is limited.

 

Structure composition

The design of the high-efficiency vertical automatic backwash filter integrates a variety of advanced technologies and materials, and its core components include:

1. Tank body. Usually made of high-quality stainless steel to ensure corrosion resistance and strength during long-term use, suitable for treating various water quality conditions.

2. Filter element. It is carefully arranged inside the filter to achieve efficient impurity interception.

3. Backwash mechanism. This is the core of the automatic backwash function, including electric actuators, electric valves and differential pressure controllers, which are responsible for monitoring the pressure difference inside the filter and initiating the backwash procedure if necessary.

4. Electronic control device. The integrated electronic control system can automatically control the operating status of the filter according to preset parameters, including the trigger timing, duration and intensity of backwashing.

5. gear reducer. The reducer is used to control the switching speed of the valve to ensure smooth and reliable operation.

6. differential pressure controller. Monitor the pressure difference between the inlet and outlet, when the pressure difference reaches the set value, trigger the backwash procedure to avoid the decrease in filtration efficiency caused by blockage.

 

Working principle

The workflow of an automatic backwash filter can be roughly divided into two stages: normal filtration and automatic backwash.

1. Normal filtration stage:

- The water to be treated enters the turbid water chamber of the filter through the water inlet. When the water flows through the filter material layer, impurities are trapped, and the purified water flows into the clean water chamber through the filter screen and is finally discharged from the water outlet.

- During this process, the built-in differential pressure controller continuously monitors the pressure difference between the water before and after filtration, which is a key basis for judging when backwashing is required.

2. Automatic backwash stage:

- When the pressure difference reaches a preset threshold, or according to a preset time period, the electronic control device activates the backwash program.

- When backwashing starts, the water outlet is closed, and the electric valve changes the direction of water flow to reverse the flow through the filter.

- Under the impact of the reverse water flow, the impurities deposited between the filter surface and the filter material are loosened and carried out of the filter with the water flow, and discharged through the sewage outlet.

- After the backwashing process is completed, the system automatically returns to the normal filtration state, and the entire process requires no manual intervention.

 

Advantages

1. Efficiency. Through precisely designed filter elements and intelligent control, it can effectively remove tiny particles and maintain clean water quality.

2. Automation. Automatic monitoring and control, reducing manual operation and operating costs.

3. Continuous operation. The backwashing process does not interrupt the water supply, ensuring the continuity and stability of the system.

4. Easy to maintain. Regular automatic cleaning reduces the frequency of manual cleaning, making maintenance simple and quick.

5. Strong adaptability. The filtration accuracy and processing capacity can be adjusted according to actual needs, making it widely applicable to a variety of working conditions.

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.
