Furniture factory dust collector

Working principle of dust collector in furniture factory:

The dust generated by the dust collector in the furniture factory during production is collected by the suction duct, and then enters the woodworking dust collector through the regulating disc valve and inlet duct. The dust is trapped outside the filter bag, and the clean gas is discharged into the atmosphere through the filter bag, induced draft fan, and chimney to meet the standard.

The dust collected by the dust collector in the furniture factory is transported to the material bin by a scraper ash conveyor, and automatically compacted by a sawdust compactor through the discharge port of the material bin. In response to the hydrophilic characteristics of wood dust and the tendency of dust to agglomerate at certain moisture levels, arching and bridging in the dust collector hopper can lead to material blockage. A vibrator is designed in the dust collector hopper to assist in dust cleaning and reduce the need for manual assistance; In response to the high concentration of wood dust, a gradual airflow channel design is adopted for the dust collector, ensuring even distribution of airflow. Designing the airflow organization to avoid high-speed flushing and wear on local areas inside the dust collector saves maintenance costs for users.

The dust generated during the production and manufacturing process of furniture factories is first collected by the dust collection system into the furniture factory dust collector equipment or woodworking dust collector collection main pipeline, and then enters the interior of the furniture factory dust collector equipment or woodworking dust collector equipment. Dust and sawdust are trapped on the outer surface by the dust collector filter bag or filter cartridge. Dry and clean air enters the clean room (also known as the clean air room) through the dust collector filter bag or filter cartridge, and is pulled by the induced draft fan through the fan and its connected chimney, and is discharged into the atmosphere in compliance with standards; The dust and sawdust trapped on the surface of the filter bag or filter cartridge are cleaned by timed pulses and fall into the equipment ash hopper. The dust collector equipment in furniture or woodworking factories adopts an integrated design, without the need for additional vibration motor assistance. According to the needs of different customers, a conveying system can be set up or directly cleaned from the ash hopper.

The dust generated during production is collected by the dust collection duct and enters the woodworking dust collector through the regulating disc valve and inlet duct. The dust is trapped outside the filter bag, and the clean gas is discharged into the atmosphere through the filter bag, induced draft fan, and chimney to meet the standards. The collected dust is transported to the silo by a scraper ash conveyor, and automatically compacted by a sawdust compactor through the silo discharge port.

Design points of dust removal system for furniture factory:

1. Small dust is difficult to collect, and a bag filter should be used, using polyester needle punched felt filter cloth with good filtering effect; The compressed air pulse cleaning method is adopted, and the cleaning effect is good.

2. Each dust point is equipped with a dust hood, with the hood facing downwards towards the direction of dust diffusion, which is beneficial for dust collection. The gaps around the dust point should be sealed as much as possible to minimize the amount of air used for dust collection, thereby reducing equipment investment and energy consumption.

3. A spiral conveyor and a star shaped unloader with air locking function are installed at the bottom of the dust collector to collect the dust collected in the dust collector for easy recycling.

4. The dust hood should be as close as possible to the dust source and as airtight as possible without affecting production and maintenance.

5. The vibrating screen vacuum hood adopts a sealing cover on the upper part of the vibrating screen. The gap between the sealing cover and the vibrating screen is sealed with a rubber plate. The front and top of the vacuum hood are equipped with movable access doors for easy maintenance.

6. The distance and height between each vacuum hood and the dust source should be reasonable, and a protective net should be set up at the vacuum port to prevent foreign objects such as plastic bottles from entering the dust collector and jamming the star shaped rotary unloader.

7. Based on the collected physical properties such as hardness and discreteness of mineral dust, combined with standard requirements and practical experience, factors such as equipment investment, motor power, and maintenance costs are comprehensively considered.

8. Design the system pipeline network according to the air volume allocated to each dust point, and select a reasonable pipeline wind speed. Simultaneously consider the pressure balance of each suction point. In addition to selecting the appropriate pipe diameter, it is necessary to install a regulating valve as an auxiliary measure to balance the pressure.
