The invention discloses an automatic cleaning type filter air inlet device for an exciter cover, which has a dust-proof brush at the upper end of the suction pipe, three to eight mesh bushes inside, and a flexible filter steel mesh can also be lifted by a mesh square pipe. There are left and right guide axle sleeves on the left and right guide axle brackets, drive axles and steel mesh axle wheel brackets on the left and right equipment brackets are equipped with steel mesh winding axle wheel and steel mesh storage axle wheel, and drive axles at the other end of the steel mesh winding axle wheel and steel mesh storage axle wheel are connected with the left reducer and the right reducer respectively. Frequency conversion motors are installed on the left and right reducers. One end of the flexible filter steel mesh is wound around the storage axle wheel of the steel mesh. The other end is fixed on the winding axle wheel of the steel mesh through the right guiding axle sleeve, dust-proof brush, bracket axle sleeve and left guiding axle sleeve. The equipment bracket has a vacuum cleaner with a vacuum hood and a vacuum tube. The vacuum cleaner and the frequency conversion motor work synchronously. The device is connected with the air intake pipe. This scheme will be widely used in the field of dust removal.

励磁机罩自动清理式过滤进风口装置
:本专利技术是用在有刷励磁汽轮发电机励磁机罩上端进风口的过滤装置。
技术介绍
:当前,有刷励磁汽轮发电机的励磁碳刷都放置一个励磁机密封罩内,通过发电机主轴上的风扇将密封罩外面的空气吸入对高温碳刷进行冷却。为了防止空气中的杂质或其它异物进入密封罩内,在密封罩上端进风口处装有过滤网。碳刷每小时需要几万立方米的空气对其冷却,每小时几万立方米空气中的杂质都会被进风口过滤网拦截捕捉,在一定面积的过滤网上面工作一段时间后就会形成杂质阻挡层,杂质阻挡层不仅造成吸入的空气减少导致碳刷温度升高,而且还会使密封罩内部的负压升高,由于负压的升高就会将在密封罩内部座式轴承中的透平油吸出,透平油与碳刷磨下来的导电粉尘混合在一起后,形成导电油泥,给发电机运行带来很大安全隐患。由于进风口的过滤网处于密封罩上端,加之过滤网本身结构,维护人员清理一次过滤网极为困难,并且也不安全。为此,本领域迫切需要一种能自动清理过滤网的过滤装置,从而消除负压给发电机运行带来安全隐患的装置。
