Principle of dust collector in furniture workshop
Woodworking dust removal can not be without three devices, pipeline system, fan system, filtration system. In these three systems, the configuration and function of different configurations are different, but the most basic principles are the same, just like a man with a mask. The pipeline is connected with woodworking machinery and filtration system, and the work of fan makes the pipeline produce negative pressure dust collection. The most important is the configuration of the fan and the performance of the filter bag.
The fan configuration is calculated according to the number of machines in the production workshop, which requires professional personnel to calculate the configuration, so that the air flow of each machine's filter interface is consistent, in order to effectively remove dust. Dust removal filter bags should be selected according to different environments. The dust properties produced in different woodworking workshops are different.
The airflow containing sawdust particles is conveyed to the diversion bin of the bag filter through the fan. The airflow velocity decreases under the action of the diversion plate. The heavier sawdust particles fall into the ash bin under the action of gravity. The other lighter dust adsorbs on the outer surface of the bag with the airflow upward. After the filter of the bag, the clean gas enters the exhaust chamber and drains out side by side. With the continuous filtering conditions, more and more dust will accumulate on the outside surface of the filter bag, which will increase the operating resistance of the system and reduce the dust removal efficiency of the system. Therefore, the system is equipped with an automatic pulse ash removal device, which consists of pulse controller, pulse valve, speed linkage, drum and spray pipe. According to the characteristics of sawdust particles, the pulse amplitude and frequency can be set on the pulse controller. After setting the pulse amplitude and frequency, the system will automatically clean the filter bag during the working process, thus greatly increasing the same filtering efficiency and prolonging the service life of the filter bag.
