摘要： A bucket lid for a cyclone dust collector is configured to fit onto a standard pail or bucket, with a circumferential rim forming an outer edge of the lid, a central mounting disk onto which the cyclone is mounted, and a series of baffles extending circumferentially around the lid between the mounting disk and the rim. These baffles extend downward into the bucket to interfere with swirl in the bucket from dust discharged from the cyclone. The baffles may be radial ribs alternating with ramped coffers. The lid may be formed of anti-static polypropylene.

摘要： A sound absorbing filter for a dust collector system is attached downstream of the system air blower and ahead of the cylindrical HEPA filter cartridge. The sound filter is formed of a cylindrical barrel or shell, favorably steel, another metal, plastics, or composite with end-caps bonded on. The cylindrical shell interior is lined with plural annular layers of sound absorbing materials. The sound absorbing elements are retained with two or more thin retainer plates The lining can comprise a radial outer layer of compressed fiber batting, and a radial inner layer of convoluted acoustic polyurethane foam 1 to 2 inches thick. The foam lining protects the fiberglass from the air flow reducing fiber shedding, and also absorbs higher frequencies, with the fiberglass being more absorptive of lower frequencies.

摘要： A dust collector arrangement has a dust separator supported on a frame, with a lid for the dust collection barrel is mounted onto the frame below it. The lid is supported at a fixed elevation above the surface of the shop floor to create a space or clearance between the rim of the dust collection barrel and the lid. The barrel is supported on casters, and can be rolled into place under the rim, and can be rolled out for emptying. Over-center latches positioned at intervals around the upper part of the barrel side wall, engage corresponding structure on the lid. These pull the barrel upwards against the lid and with the barrel casters lifted off the floor surface. The latch members release to lower the barrel for emptying.

摘要： A cyclonic dust collector arrangement employs a cyclone that has a conic body formed of a conic wall. An upper divider plate closes off the upper end of the conic body, with a vortex tube descending from a central passage in the divider plate. The conic body has a narrow nose at a lower end so that the upper divider plate and the lower nose define a cyclonic chamber within the conic body. The inlet conduit penetrates the conic wall below the divider plate. The fan chamber of the separator is mounted above the divider plate, and serves to induce air flow from the inlet conduit into the cyclonic chamber, and through said vortex tube into the fan chamber. The air is discharged through a final filter. This construction has reduced manufacture costs and improved dust separation.

摘要： A vacuum bag hold-down arrangement for a dust collection system maintains a negative pressure in the space between a dust collection drum and a plastic film liner or bag in the drum. A cyclonic separator at the station separates the dust from an air flow and deposits it into the liner in the drum. The hold-down arrangement employs a vacuum pump producing about 1 to 3 psig negative pressure. A vacuum conduit extends from the pump through a penetration in the drum and into the space between wall of the drum and the liner bag. A porous pad, e.g., open cell foam, is situated over the vacuum conduit and separates the bag liner from the vacuum conduit. This distributes the air flow into the vacuum conduit and creates a more uniform grip of the liner or bag to the drum.
摘要翻译： 用于集尘系统的真空袋压紧装置在集尘鼓和鼓中的塑料膜衬里或袋之间的空间中保持负压。 车站处的旋风分离器将灰尘与空气流分离，并将其沉积在滚筒内的衬垫中。 压紧装置使用产生约1至3psig负压的真空泵。 真空导管从泵延伸通过滚筒中的穿透并进入滚筒的壁与衬里袋之间的空间。 多孔垫，例如开孔泡沫，位于真空导管上方，并将袋衬里与真空导管分开。 这将空气流分配到真空管道中，并使衬套或袋子更均匀地夹在滚筒上。

摘要： A cyclonic portable vacuum cleaner/dust collector for workshop or other use has a conic body that is supported on a hand cart or dolly. A funnel shaped divider plate within the conic body divides it into a cyclonic chamber between the divider plate and the lower nose, and a filter chamber between the divider plate and a motor plate that closes the upper mouth of the conic body. The filter chamber contains a filter cartridge. A vacuum air pump is mounted on the motor plate, and is covered by a shroud or housing. Clean, filtered air is exhausted into the ambient. Process dust settled into a dust collection drum supported beneath the nose of the conic body. A pulse cleaning arrangement serves for periodic filter cleaning. The supporting cart can be wheeled or can use a wall bracket for wall mounting.
