Introduction to the process design of porous plate for dust collector
The flower plate of dust collector is used to bear the holes of the bag and frame! In the negative pressure dust collector, the upper flower plate is part of the upper box, and the flower board also plays an insulating role. In the upper box and middle box, the dust-laden gas enters the middle box from the ash hopper. After being filtered by the bag, the clean gas enters the upper box through the hole in the flower plate, and then is discharged into the air through the chimney!
In the pressure dust collector, the flower plate is between the ash hopper and the middle box, and the bag hangs upside down without a frame. It also serves to isolate the dust-laden gas and clean gas! The requirements for the flower plate holes are both positive and negative. Within one millimeter, the surface must be smooth! Only in this way can the bag be tightly and firmly stuck. We can make flower boards of different specifications according to customer needs. [

Precautions for the design of the dust collector flower board:
The flower board must bear not only the negative pressure of the system, but also the weight of the filter bag, dust layer and bag cage. Deformation may affect the straightness of the filter bag and the sealing effect at the bag mouth. The lower part of the flower board should be strengthened during design.
The flower board of the dust collector should be smooth and smooth, without defects such as deflection or unevenness, and its flatness deviation should not be greater than / of the length of the flower board. The periphery of the aperture of the flower plate must be smooth and free of burrs. The aperture tolerance of the flower plate that uses an elastic expansion ring to fix the filter bag is plus or minus .3. The deviation between the installation position and the theoretical position after processing of the flower plate aperture should be less than. The flatness deviation shall not be greater than // of the length of the flower board.
