Introduction

Dust plate is also called dust collector plate, dust steel partition. The flower plate refers to a steel partition plate with holes of the same size for installing dust filter bags. In the design of dust removal plate, the distance between the holes of the dust removal filter bag is mainly arranged, which is related to the bag diameter, bag length, dust nature, filtration speed and other factors. If the distance between the holes is too tight, the bottom of the filter bag will collide and wear each other, and part of the bottom of the filter bag will break within a few months. It will also cause the airflow in the box to rise too fast, resulting in an increase in soot emissions, too high local filtration load of the filter material and insufficient ash removal rate. For example, the center of the bag of a dust collector is 250mm from the wall plate, the distance between the fool blowing holes of the blowing pipe is 200mm, the diameter of the bag is 160mm, and the length is 6m. Because the distance between the bag and the bag is only 40mmm, the bottom of the filter bag collides with each other and wears, and the bottom of some filter bags is broken after several months of operation.

Technical parameters

Processing Method of Dust Collector Board

1. Stamping processing

Stamping processing is processed by mechanical or hydraulic equipment. The advantages are high precision, smooth hole wall and low cost. Our company processes dust collector plates all the year round.

2. Laser cutting

Laser cutting is the use of high-power high-speed laser cutting, the advantage is that the plate is not easy to deform, the hole wall is smooth. The disadvantage is that the precision is low, the plate must meet the technical requirements, and the speed is slow.

3. Milling machine processing

Milling machine processing is the use of large milling machine with drilling processing, the advantages of hole wall is smooth, not easy to deformation. The disadvantage is that the processing accuracy is relatively low and the speed is very slow, and the relative cost is very high.

In summary, the use of stamping processing.

According to my company for many years of practical production experience, we concluded that if the dust collector plate hole and hole interval between too close, it will lead to dust bag bottom collision between each other, causing wear. When the operation reaches a certain level, the bottom of the dust collector bag will break, which will also lead to the acceleration of the rising speed of the airflow in the box, so that the emission of smoke and dust will increase.

Dust removal board not only to bear the negative pressure of the system, but also to bear the weight of the dust bag, dust layer and dust removal skeleton. The deformation of the board is likely to affect the verticality of the filter bag and the sealing effect at the mouth of the bag. When designing the board, we should strengthen the lower part of the board, which is a problem that we must pay attention to when designing and making.
