Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.

In a method of treating a gas stream (32) containing combustible and/or reactive particles (34) at least a part of the particles (34) contained in the gas stream (32) is separated from the gas stream (32) by means of a separation device (36). The particles (34) separated from the gas stream (32) by means of the separation device (36) are supplied to a collecting vessel (40). The supply of particles (34) to the collecting vessel (40) is interrupted. A flame retardant material (57) is supplied to the collecting vessel (40) so as to form a cover layer of flame retardant material (57) on the particles (34) contained in the collecting vessel (40).

A dust mitigation system for a mobile sweeper, the dust mitigation system including a cover to at least partially cover one or more brushes of the mobile sweeper, a dust collector including at least one fan and one or more filters, and at least one duct fluidly connecting the cover with the dust collector.

The present invention discloses an air purifier, including: an air intake structure and an air discharge structure. The air intake structure is connected and fixed to the air discharge structure via a quick-release structure, the air intake structure is provided with a filter screen, and placement/removal of the filter screen is enabled through engagement/disengagement of the quick-release structure. The air purifier of the present invention has a simple structure and a rational design. The air purifier is divided into two parts, namely an air discharge structure and an air intake structure which are arranged one above the other, and quick dismounting and mounting of the upper part and the lower part are enabled by means of the quick-release structure, thereby realizing quick and easy replacement of the filter screen, and effectively improving the replacement efficiency. In addition, the air purifier has a simple and attractive appearance.

A handheld air purifier may include a suction body provided with a fan to suction air and a filter to filter foreign matter from the sucked air, a handle extending from the suction body, and an agitator provided in the suction body to loosen or scatter dust from a garment. The handheld air purifier may be configured to be attached to and detached from a main air purifier, and the main air purifier may suction dust off the handheld air purifier and sterilize the handheld air purifier when the handheld air purifier is mounted on the main air purifier. The agitator of the handheld air purifier may have a striking member exposed through a lower surface of the suction body, and may move out of and into the suction body to strike the garment so that the dust may be loosened and suctioned into the suction body and filtered by the filter.
