  A suction port 61 is formed on the front surface of the housing 2 so as to be connected to a dust collecting chamber 3 to be described later and to take in air, dust and the like from the outside to the inside of the dust collecting apparatus 1. For example, a duct (not shown) connected to a facility for generating dust or the like such as a factory is connected to the suction port 61. In addition, an exhaust port 62 is formed in the upper part of the housing 2 for discharging the air purified by the dust collector 1 to the clean chamber 4 described later. For example, an exhaust duct (not shown) may be connected to the exhaust port 62.

  The hopper 50 is formed such that the upper part is large in the horizontal direction and the lower part is small in the horizontal direction. That is, the hopper 50 is formed in a substantially funnel shape. The upper part of the hopper 50 is connected to the lowermost panel member 10 and the lower part of the panel member 20, and a discharge port for discharging dust or the like is formed in the lower part of the hopper 50. The discharge port is provided with a rotary valve 64 for discharging collected dust and the like to the outside. Note that a dust box or the like for collecting dust or the like may be provided inside the housing 2 instead of the hopper 50.

  FIG. 2 is a schematic longitudinal sectional view showing a schematic configuration of the dust collector 1. Note that the various arrows shown in FIG. 2 indicate the flow of air. As shown in FIG. 2, a filter 60 for capturing dust and the like, and a filter support plate 63 for supporting the filter 60 are provided inside the housing 2.

  The filter 60 is a substantially cylindrical filter cloth filter, and is formed of various synthetic fibers such as polyester fibers, for example. In addition, the filter 60 can employ | adopt various materials and forms suitable for each use according to the dust etc. of the object to remove. For example, the filter 60 may be a detachable cartridge type filter.

  The filter support plate 63 is a substantially plate-like member formed of, for example, a steel plate or the like, and is attached to the upper part inside the housing 2, and the interior of the housing 2 is connected to the lower dust collection chamber 3 and the upper clean chamber 4.
