Customizable Wedge wire drum screen for Your Needs

some description about product

Wedge wire drum screen is a type of filtration device used in various industries for solid-liquid separation. It consists of a cylindrical drum with wedge-shaped wires wrapped around it, forming a series of continuous V-shaped slots.

The construction of a wedge wire drum screen involves high-quality stainless steel wires that are wrapped around support rods to form the V-shaped slots. Stainless steel is preferred due to its corrosion resistance, durability, and ability to withstand demanding operating conditions.

The drum screens can be customized based on specific application requirements, such as slot size, drum diameter, and length. The slot size can be selected to achieve the desired particle separation efficiency and prevent the passage of unwanted solids.

The wedge wire drum screen operates by rotating on its axis, allowing the mixture of solid and liquid to pass through the slots while retaining larger solids within the drum. The rotation of the drum creates a self-cleaning effect, as the solids are lifted and rolled over the screen surface, enabling the liquid to pass through. This mechanism helps prevent clogging and ensures continuous operation.

Wedge Wire Profile: The wedge wire profile is the most critical component of a wedge wire drum screen. It is a continuous V-shaped wire wrapped around support rods, forming a slotted screen surface. This profile is typically made from stainless steel due to its corrosion resistance and structural strength. The precise shape and dimensions of the wedge wire are essential for efficient filtration and screening.

Support Rods: Support rods are used to hold the wedge wire profiles in place and maintain the desired slot openings. These rods run parallel to the drum’s axis and are typically made from stainless steel or another high-strength material. The spacing and diameter of the support rods are carefully engineered to ensure proper screen integrity and prevent deformation.

Wedge wire drum screen production process

Wedge wire drum screen production process

The production process of wedge wire drum screens involves meticulous steps to create a durable and effective filtration component. It begins with the selection of high-quality stainless steel, chosen for its corrosion resistance and strength. Wedge wire profiles are manufactured by winding V-shaped wire onto support rods, ensuring precise slot openings. Support rods, typically made of stainless steel, are produced separately. The profiles are then meticulously assembled onto the support rods to create the screen surface.

How are the wedge wire profiles on the drum screen selected and designed for specific applications and particle separation requirements?

Material of wedge wire drum screen

The selection and design of wedge wire profiles on a drum screen are critical for tailoring the screen to meet specific application and particle separation requirements. It begins with a thorough understanding of the application’s needs, including the particle size distribution, desired filtration efficiency, flow rates, and environmental conditions.

The slot opening size is a key parameter and is determined based on the size of particles to be separated. Smaller slot openings are effective for fine particles, while larger openings allow larger particles to pass through. The shape and dimensions of the wedge wire profiles are engineered to meet filtration specifications, influencing structural integrity and particle capture.

Profile spacing affects open area percentage, flow rates, and solids loading capacity. Material selection, often stainless steel, considers corrosion resistance and durability. Customization options allow for precise slot size, profile shape, dimensions, and spacing.

Filtration Through Wedge Wire: The outer surface of the drum screen is wrapped with a wedge wire screen. This screen features precise V-shaped wire profiles that are oriented parallel to the drum’s axis. These wires are spaced to create slots or openings of a specified size.

Particle Capture: As the fluid flows through the drum screen, the particles or solids that are larger than the slot openings on the screen surface are captured and retained on the outside of the drum.

Fluid Passage: The filtered fluid, now free from the captured particles, passes through the slots and continues its flow toward the interior of the drum.

 

Collection and Discharge: The collected solids accumulate on the external surface of the wedge wire screen. As the drum continues to rotate, a portion of the screen emerges from the fluid flow, and the accumulated solids are scraped or washed off by a cleaning mechanism, if present.

Effluent Discharge: The cleaned fluid, now devoid of captured particles, exits the drum screen through an outlet at the opposite end.

Wedge wire drum screen and the sintered titanium filter are two different types of filtration systems with distinct characteristics. Here are some key points of comparison between the two:

 

1.Filtration mechanism: The wedge wire drum screen relies on a physical separation process, where solid particles are retained on the surface of the drum while allowing clean liquid to pass through. In contrast, the sintered titanium filter utilizes a porous structure to capture and trap particles within the filter media.

 

2.Filtration efficiency: Both systems can offer high filtration efficiency. The wedge wire drum screen is effective in removing larger solid particles, while the sintered titanium filter can capture finer particles depending on its pore size.

 

3.Construction material: The wedge wire drum screen is typically constructed using stainless steel, while the sintered titanium filter is made of titanium powder that is sintered together to form a solid structure. Titanium offers excellent corrosion resistance, making it suitable for chemically aggressive environments.

 

4.Maintenance and cleanability: The wedge wire drum screen is generally easier to clean and maintain due to its accessible surface. In contrast, the sintered titanium filter may require backwashing or chemical cleaning to remove trapped particles from within the porous structure.

Wedge screen drum effectively separates solids from liquids or classifies materials through its unique design and operating principles:

 

1.Wedge wire panels: The drum is constructed using wedge wire panels with precise V-shaped slots. These slots allow liquid to pass through while retaining solid particles larger than the slot size.

 

2.Rotation and inclination: The drum is set in motion, rotating at a specific speed and inclined angle. This motion facilitates the movement of the solids along the drum’s surface.

 

3.Filtration and retention: As the liquid flows through the wedge wire panels, solids are captured and retained on the drum’s surface. The shape and spacing of the wedge wire panels prevent clogging and ensure efficient separation.

 

4.Self-cleaning mechanism: The rotation of the drum and the angle of inclination contribute to a self-cleaning mechanism. The solids gradually move towards the discharge end of the drum, while the liquid continues to pass through the screens.

 

5.Discharge of solids: At the discharge end, the retained solids are effectively discharged from the drum, either through scraping, vibration, or other mechanisms, depending on the specific design.

Wedge wire drum screens require regular maintenance procedures to ensure their optimal performance and longevity. Here are some common maintenance procedures for it:

 

1.Regular inspection: Conduct routine inspections of the drum screen to identify any signs of wear, damage, or clogging. Inspect the wedge wire panels for any bent wires, loose connections, or blockages that may affect the filtration efficiency.

 

2.Cleaning: Clean the drum screen regularly to prevent the accumulation of solids and maintain optimal performance. Depending on the application and level of fouling, cleaning can be done manually with brushes, water jets, or automated cleaning systems.
