Wedge metal wire mesh drum filter
Introduction to wedge-shaped metal wire mesh drum filter
The wedge-shaped metal wire mesh drum filter is welded with wedge-shaped stainless steel wire and support bars as the core structure, forming a V-shaped slot filter channel. Its uniqueness lies in the smooth wedge-shaped surface of the filter surface, with gaps gradually expanding from the inside out. This design ensures high-precision filtration and achieves self-cleaning function through a small inner and large outer gap structure. The filter cartridge is made of 304 or 316L stainless steel material, which has corrosion resistance and high temperature resistance, and can withstand a high temperature environment of 480 ℃. The equipment drives the filter cartridge to rotate through a rotary drive system, combined with backwashing or mechanical scraper devices, to achieve continuous filtration and automatic cleaning, and is widely used in the field of industrial fluid treatment.
Characteristics of wedge-shaped metal wire mesh drum filter
The core advantage of this device lies in the balance between structural strength and filtration efficiency. Each intersection point between the wedge-shaped wire and the support bar is welded and reinforced, forming a high-strength honeycomb structure with a pressure resistance of over 10MPa and mechanical stability far exceeding that of traditional sieves. Its filtering accuracy range covers 0.1 μ m to 10mm, capable of intercepting micron sized suspended solids and processing millimeter sized particles, with a gap uniformity error controlled within ± 0.02mm. During backwashing, water flows from the outside to the inside of the filter cartridge, and with the centrifugal force generated by rotation, blockages can be completely removed, resulting in a 60% increase in cleaning efficiency compared to ordinary filters. In addition, modular design supports quick replacement of filter cartridges, reducing single maintenance time to within 30 minutes and significantly reducing downtime costs.
Scope of use of wedge-shaped metal wire mesh drum filter
This device has achieved large-scale applications in multiple industries. In the field of petrochemicals, its high temperature resistance makes it the core component of oil slurry filtration in catalytic cracking units, which can intercept catalyst particles and extend equipment life; In the water treatment industry, when used in conjunction with MBR membrane systems, it can reduce membrane fouling rates and improve effluent quality to meet Class III standards for surface water; In the food industry, 316L material filter cartridges are used for filtering beer saccharification mash. After filtration, the light transmittance of the wort reaches over 98%, and there is no risk of metal ion leaching. In the field of environmental protection, this equipment has been successfully applied to the deep treatment of printing and dyeing wastewater. By using a 0.5mm precision filter to intercept dye molecules and combining it with ozone oxidation technology, the wastewater reuse rate has exceeded 85%, significantly reducing the water cost for enterprises.
