Background technology
Timber work is typically the basic production process of Furniture Factory, can generate many powder not of uniform size in process of production
Dirt, dust are mainly derived from the processing operation such as saw, milling, plane and sanding, and such dirt dust concentration is larger, and health is caused to endanger
Evil.
The current dust pelletizing system overwhelming majority is using by the air with dust, by filter bag, little particle adsorbing powder dust is in filter bag
On, under clearing up filter bag after a period of time or being trembled the dust adsorbed on filter bag using pulser, then carry out clear
Reason；Filter bag is directly cleared up, it is necessary to repeatedly dismantle, implement highly difficult, be suitble to small dust-extraction unit；Dust is trembled down
It is cleared up again afterwards, the dust cleaner used at present all cannot effectively clean up dirt in time, be easy to cause blocking, reduce
The dust removal performance of dust pelletizing system.
The dust that timber work generates is more, and range of scatter is big, it is necessary to carry out dust removal operation using large-scale dust pelletizing system, by
Big in dust concentration, in dedusting, dust can be deposited on deduster bottom, be negative pressure state inside deduster, if clearing up not in time
The dust accumulation of bottom in the process of circulation of deduster inner air, can raise dust accumulation, and dust accumulation can return to the air of non-dedusting once again
In, further increase dust concentration, make to be deposited on the acceleration of the dust on filter bag and reach saturation state；Clear dirt in deduster at present
Device is difficult to meet large-scale dust pelletizing system, causes dust removing effects poor.
The control system of current deduster is the operation of simple control device, it is difficult to make the air quantity of air-introduced machine and remove
Air volumematching needed for dirt device, makes the energy consumption of entire deduster increase.
