DYD-JS Series Dual-Arm Welding Fume Extractor

The DYD-JS Series Dual-Arm Welding Fume Extractor is a high-performance and eco-conscious fume control system developed by Qingdao Decent Group. This equipment line is engineered to effectively manage and purify fumes and dust from welding, polishing, cutting, and grinding operations.

Product Details

The DYD-JS Series Dual-Arm Welding Fume Extractor is tailored for efficient fume and dust extraction in dual-station welding and grinding processes. It is distinguished by its high purification capabilities and adaptability to various industrial settings. Below is an in-depth overview of the product series.

Applicable Scope

  • Ideal for smoke and dust purification during welding, polishing, cutting, and grinding processes.
  • Perfect for environments requiring localized smoke and dust extraction.

Working Principle

  • The system operates by creating a negative pressure via the fan, which draws in fumes and dust.
  • The pollutants pass through a filtration system where they are trapped by the filter cartridges, and the clean air is recirculated into the workspace.

Main Features

  • Dual-Arm Adaptability: The dual-arm configuration covers a broader range of workstations, enhancing purification capabilities.
  • High-Efficiency Filtration: Utilizes high-grade PTFE coated long-fiber polyester non-woven filter cartridges, capturing over 99.9% of dust particles larger than 0.3 microns.
  • Low Maintenance: The filter cartridges are easily cleaned with pulse jet technology, ensuring a service life of up to 5,000 hours under normal conditions.
  • Automatic Dust Removal: The pulse spray system offers adjustable pulse intensity and frequency for optimal and efficient dust removal.
  • Compact and Mobile: The compact design includes casters and handles for easy relocation within the workspace.

Core Components of Dust Removal

  • Filter Elements: The PTFE coated long-fiber polyester non-woven filter cartridges are designed for high-efficiency dust capture and durability under high pressure.
  • Operational State: The cartridges function in a ventilated state and are maintained through pulse jet cleaning for consistent performance.
  • Pulse Jet Cleaning System: This system uses compressed air to generate pulsed airflows, dislodging accumulated dust from the filter cartridges and maintaining their cleanliness.

Core Components of Dust Removal

High filter cartridge as the filtering element, PTFE membrane filter, for the adhesion of dust,PTFE coated filter element can filter dust particles reach 0.3um (optonal higher eve of filtraton), the filtration efficiency reached 99.99%.Even if the ambient temperature is lower than the dew point temperature. The filter element also maintains a stable filtration capacity.PTFE membrane filter has the advantages of membrane filtration and rigid body filtration, and small volume, large filtration area of rigid filter allows high working pressure, and has a very long service life. Mainly used for the treatment of various toxic and harmful ultrafine dust and smoke, caution should be exercised in oily smoke environments, and additional membrane materials may be required for use.

Self-cleaning Principle of Cartridge

Purifier filter cleaning by pulse jet structure: when the purifier running after a period of time, fine dust adsorbed on the surface of the filter, the reduced permeability filter, dust absorption filter surface is cleared in the flow, fall in the lower chamber of the dust hopper.

Pulse injection requires clean compressed air of 0.4-0.6Mpa, and constant and constant air supply must be maintained during operation.

Working Principle of Filter Tube Dedusting

Ash Cleaning System

Cartridge filter cleaning with compressed air pulse cleaning, now through the microcomputer control timing or manual start function of pulse jet injection valve, the filter cylinder radial deformation, shake off the dust. The pipeline system is fixed in the box with the support, and the positioning pin is set, so that the accurate reset can be ensured when the equipment is maintained and maintained.

Compressed air piping system for diversion of compressed air, compressed air helps in the blowing process stability, can improve the cleaning system running stability, effectively reduce the equipment running resistance, reduce the energy consumption of the system. The ash cleaning system is equipped with gas distribution bag and precision filter (oil, water and dust) to ensure the pressure, gas volume and quality of the gas supply. The dust cleaning and ash cleaning capacity can meet the demand of dust cleaning under various working conditions.

Electromagnetic Pulse Valve

The key equipment of the ash cleaning system is the electromagnetic pulse valve, and its selection is related to the dust removal effect of the dust remover and the stability and reliability of the equipment. Can effectively reduce the operation and maintenance costs. We use the electromagnetic pulse valve to dust, blowing pressure 0.7MPA, DC24V 1.0"in the workload, gas pressure is MPA, pulse jet time 0.2S, single electromagnetic pulse valve injection when the compressed air consumption 30L, greatly reduce the compressed air consumption, can effectively reduce the workload of the compressed air station.
