What is the flower plate of the bag filter equipment? The flower plate, as the name implies, is a partition. The flower plate separates the dust chamber from the air purification chamber. A lot of small circular holes are opened in the flower plate. These holes are used to fix the dust bag. The clean air passes through the dust-removing cloth bag and reaches the air-cleaning chamber through the circular hole on the flower plate, and then is discharged from the chimney to the upper air.
The flower board must not only bear the negative pressure of the system, but also bear the weight of the dust bag, dust layer and dust bag cage. If the dust collector flower plate is deformed, it will affect the straightness of the dust removal cloth bag and the sealing effect at the bag mouth. Therefore, it is recommended that in the initial design, the lower part of the dust collector porous plate should be strengthened.
The design and requirements of the flower plate of the bag dust collector are as follows:
- The flower plate of the bag dust collector should be smooth and flat, and should not have deflection, uneven uneven defects, and the deviation of its flatness should not be greater than 2/1000 of the length of the flower plate;
- The periphery of the hole diameter of the cloth dust collector flower plate should be smooth and free of burrs. The tolerance of the hole diameter of the dust collector flower plate that fixes the filter bag of the dust collector with an elastic expansion ring is about ± 0.3mm;
- The deviation between the installation position of the dust collector flower plate aperture and the theoretical position should be less than 1.5mm, and the deviation of the flatness should not be greater than 2/1000 of the length of the dust collector flower plate.
The distance between the holes of the flower plate holes of the bag dust collector is too close, which will cause the bottoms of the dust filter bags to collide with each other and wear out. The rising speed is accelerated, which leads to the continuous increase of smoke and dust emissions, the local filtering load of the filter material is constantly increasing, and the cleaning power is insufficient.
