Laser cutting and dust removal equipment is one of the most important things for the dust generated during the laser cutting process. Laser cutting dust removal equipment produced by Yuchen dust removal equipment manufacturers. Co., Ltd. Based on the nature of smoke production, it has professional and targeted dust removal skills .Related introduction of laser cutting dust removal equipmentThe following tells you about the three starting points of the nature of laser soot:
1. Laser melting and cutting When the power density of the incident laser beam exceeds a certain value, the material in the irradiated area starts to evaporate, forming holes, and at the same time, the material near the speed of light melts. Then, the auxiliary airflow coaxial with the speed of light takes away the surrounding molten material, forming smoke and dust.
2. Under the heating of a high power density laser beam, about 40% of the material evaporates into steam and disappears. 60% of the material is blown away from the bottom of the slit by the auxiliary gas as a jet, and the auxiliary gas combines with particles in the air to form dust.
3. Under the irradiation of the laser beam, the surface of the laser oxidized cutting material is rapidly heated to the ignition point temperature, and then violently reacts with oxygen and releases a lot of heat, thereby forming small holes filled with steam inside the material, and the periphery of the small holes is Surrounded by a wall of molten metal. These vapors and molten materials are carried away by the auxiliary air flow and float in the workshop, forming dust and smoke.

尘 的 气体 被 风机的负压通过管道吸入激光切割除尘设备的箱体内， 采用滤筒 除尘式 进行过滤，粉尘被 隔离在 滤筒的表面 外层 ，净化后的 洁净 气体通过滤筒 中心 进入风机， 被 风机吸入直接 从消声器上南 排出。 The gas with dust is sucked into the box of the laser cutting dust removal equipment by the negative pressure of the fan through the pipeline, and the filter is used to filter the dust . The dust is isolated on the outer layer of the surface of the filter , and the purified clean gas passes through the center of the filter. Enter the fan, sucked in by the fan and discharged directly from the muffler .
激光切割除尘设备运行 时间的 增加 ， 滤筒的表面 外层 粉尘不断地增加， 滤筒阻力随之上升，从而影响除尘器的除尘效果， 一般 采用了自 去 清灰机构进行 定时对滤袋进行喷吹 ， 让 粘在滤筒 外层 的粉尘抖落下来，落入灰斗抽屉中。 As the operating time of the laser cutting dust removal equipment increases , the dust on the outer surface of the filter cartridge increases continuously, and the resistance of the filter cartridge rises, which affects the dust removal effect of the dust collector. Generally, a self- cleaning dust removal mechanism is used to periodically filter the filter bag Blow on and let the dust sticking to the outer layer of the filter cartridge shake off and fall into the ash drawer.
