The fiber gaps of the traditional filter material are 12-60 microns, when dust particles pass through the gaps, the dust particles enter the filter material and can block the gaps of the filter material, so that the filtering efficiency is reduced, the pulse back blowing work cannot effectively blow the dust blocked in the gaps, the resistance of the dust remover continuously rises along with the continuous deterioration of the blocking condition, the air handling capacity of the dust removal system is reduced, and the dust removal effect is seriously influenced.

The utility model discloses a work flow is, on the reasonable position of roller way conveying system 1 was hung into to the quilt shot blasting work piece of assigned position by intelligent driving system, then started the action by frequency conversion gear motor drive work piece roller way input system 1. When a workpiece is conveyed to a projecting area of the shot blasting antechamber 21 from the conveying roller way 11, the electric shutter door 211 on the chamber body of the shot blasting antechamber 21 is controlled to be closed by the photoelectric switch, the whole body of the workpiece is struck and abraded by intensive shot flow beams of 16 shot blasting devices 221 from different angles, and oxide skin and dirt attached to the workpiece quickly fall off under strong impact, so that the workpiece is smooth and clean in certain roughness, and meanwhile, the internal stress of the workpiece is eliminated, and the workpiece is prevented from being deformed. If a part of a special workpiece has dead corners which are not cleaned, the workpiece enters the supplementary spraying chamber 23, the supplementary spraying robot 41 can automatically supplement spraying, according to the shapes of different workpieces and the positions of the dead corners, the supplementary spraying is automatically performed according to a program with a set number, the workpiece enters the shot blasting rear chamber 24 to perform soot blowing treatment after the supplementary spraying is finished, the soot blowing robot 43 automatically blows soot, after the whole program is finished, the roller way automatically reverses, the workpiece which is finished with shot blasting returns to the specified position of the roller way 11, and then the workpiece which is finished with shot blasting is hung into a specified storage area through an intelligent traveling crane to perform a coating process. In the shot blasting cleaning process, the falling shot slag mixture is conveyed to a first-stage longitudinal screw conveyor 28 through a longitudinal second-stage longitudinal screw conveyor 26, then conveyed to a first-stage transverse screw conveyor 29 through the first-stage longitudinal screw conveyor 28, then lifted and conveyed to a shot-sand separator 32 through a bucket elevator 31, and under the separation of the shot-sand separator 32, pure shots fall into a shot bin 323 and are thrown out through a shot blasting machine 221 through a shot conveying system, so that the shots are fully recycled. In the circulation process of the pill materials, all motors are of a variable-frequency energy-saving type, and the running speed of the motors is adjusted at any time through the magnitude of the induction torque force, so that smooth circulation of the pill materials is ensured, and the optimal energy-saving effect is kept. The dust-air mixture from the shot-sand separator 32 and the shot blasting system 2 passes through the dust removal pipeline 52 under the adsorption attraction of the variable-frequency centrifugal fan 512, enters the primary pre-cyclone body 513, then enters the secondary filter cartridge dust remover 511 for dust removal, the particle dust is captured and collected, and the purified air passes through the smokeThe chimney is discharged into the atmosphere, the dust removal efficiency can reach 99 percent, the dust is discharged at high altitude after being treated by a dust remover, and the discharge concentration is less than or equal to 10mg/m ³ 。
