CIRCULAR SAW APPARATUS WITH INTEGRATED MULTISTAGE FILTRATION SYSTEM

Various dust collection apparatuses are disclosed. In a first example， a dust collection apparatus includes a vacuum source configured to provide a negative pressure， and a multistage filter configured to collect airborne dust drawn by the negative pressure. For this example， the dust collection apparatus includes a dust tray having a shared dust containment area in which the shared dust containment area is a single compartment configured to receive the airborne dust collected by the multistage filter directly from each of a plurality of stages of the multistage filter. In another example， a dust collection apparatus includes a filter， a filter housing configured to house the filter， and an inlet coupled to the filter housing. For this example， the inlet is configured to receive a flow of airborne dust drawn by a negative pressure， and is further configured to mitigate an impact of the airborne dust on the filter.

本公开公开了多种集尘装置。在第一个示例中，集尘装置包含用于提供负压的真空源，以及用于收集由该负压抽吸而来的悬浮粉尘的多级过滤器。针对该示例，该集尘装置包含带有共用集尘区域的集尘盘，其中该共用集尘区域为单个腔体，用于直接接收多级过滤器各层级所收集到的悬浮粉尘。在另一示例中，集尘装置包含过滤器、用于容纳该过滤器的过滤器壳体，以及与该过滤器壳体相连的进气口。针对该示例，该进气口用于接收由负压抽吸而来的悬浮粉尘气流，同时还可减缓悬浮粉尘对过滤器的冲击。
