A cyclone type receiver can be used in a pneumatic conveyor system for accurately delivering a wide variety of particulate materials. A receiver may include a cylindrical body configured to hold a filter. The top end of the cylindrical body may include an air inlet for receiving a ducted air stream filled with a particulate material, and may be configured to convey the ducted air stream helically toward a conical section attached to the cylindrical section. The conical section may be configured to route the ducted air in a helical manner to remove the particulate material from the ducted air. In such a configuration, the filter and the conical section may remove particulate material, thereby preferably increasing the transfer accuracy of the system and reducing the footprint of a traditional pneumatic conveyor system.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module where the intake module is above the vortex module, which is above the disk-pack module and the motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

Exemplary embodiments are directed to pool cleaners that remove debris from water using a plurality of cyclonic flows, or that include a removable impeller subassembly, a check valve for a debris canister, a particle separator assembly having a handle that locks to the pool cleaner, a modular roller drive gear box, or a roller latch that secures a roller to the pool cleaner. Exemplary embodiments are also directed to the check valve and the roller latch themselves. Exemplary embodiments are directed to a filter medium for pool cleaners that includes embossments providing flow channels for water, and to roller assemblies for pool cleaners. Exemplary embodiments are directed to pool cleaners including alternative pump motor engagements. Exemplary embodiments are directed to pool cleaners power supplies that include a potted and contoured power board assembly, and to kickstands therefor. Exemplary embodiments are directed to a pool cleaner caddy, and removable wheels therefor.

The present invention relates to a cotton opening and dust collecting device for refined cotton, which comprises a first cyclone separator, a second cyclone separator, a first draught fan, a second draught fan and a spiral conveyer, and further comprises a suction pipe, a dust collecting cabin, a screen plate, a motor, a dust extraction pipe, a first bearing, a second bearing, a first pipeline, a second pipeline, a third pipeline and a forth pipeline. The device is able to complete collection to the cotton dust in the air in the cotton opening workshop, which not only can effectively prevent the screen plate from being blocked by the cotton dust, but also has good dust collection effect and complete collection of cotton dust.

The present invention refers to an accelerating cyclone that separates solid particles, comprising in its general structure a lower conical body (1) (17A and 17B), comprising a lower opening (18), a central cylindrical body (2) immediately above the conical body (1) whose diameter is smaller than the largest diameter of the conical body cone (1), and a third upper, also cylindrical, body (3) of smaller diameter than the diameter of the central cylindrical body (2), comprising a side opening for the acceleration air output (5); where the cylindrical central body (2) allows to accelerate the speed of the solid material particles and is the cyclone pressure chamber; and where said cylindrical central body (2) comprises a side opening for the acceleration air input (8) and at least one duct (9).
