摘要
为解决现有除尘机组存在的问题,经对比各种除尘机组中的滤料布置形式、吸嘴形式、吸臂形式,我设计了复合筒式除尘机组。该机组采用轮带式轮流吸尘机构、具有非标准技术的粉尘分离压紧器、FM滤料、XF3型纤维分离器等, 并将一级圆盘过滤器的吸尘风机置于纤维分离器之前,结构设计有利于纤尘的集中回收。本机组主要是运用行星轮的传动，实现固定的速比。我重点分析了除尘机组的间歇吸尘机构和除尘器吸臂吸嘴的性能与结构特点。在设计过程中尽量使用标准件，对于部分不关键的零件可适当降低尺寸公差要求，有利于设计成本的降低。本机组中，多处结构是对称的，这样降低了设计的难度。经调研知, 该机组的粉尘处理能力大于30 kg /h, 纤维处理量可达150 kg /h以上。

Abstract
In order to resolve the existing problems in duster, multifunctional round cage duster was designed through comparing the filter disposal form, suction nozzle form and suction arm of all kinds of duster. Wheel suctionm echanism, dust separation presser with nonstandard, FM filter, XF-3 fiber separator and so on were adopted in multifunctional round cage duster. The suction fan of the first grade disk filter was set before fiber separator, the structure design is feasib le to recycle fibers and dust.The unit is mainly to make use of Planetary wheel transmission ,to realize the fixed speed transmission. I emphatically analyzes intermittent dust suction mechanism and dust nozzle of dust extraction unit.In the design process to use standard parts as far as possible，to solve the key parts for not properly reduce dimension tolerance requirement，to use standard design cost reduction.The unit, several structure is symmetrical, such reduced design of difficulty. Known by the investigation，the dust treatm ent ab ility o f duste r is above 30 kg /h, and the amount of fiber treatment can reach m ore than 150 kg /h.
