  • Patent number: 8734751
    Abstract: A method is provided for recycling and treating the wastes of silicon wafer cutting and polishing processes. To begin with, a dewatered filter cake is mixed with water so that the filter cake is diluted to form a working fluid. The water reacts with silicon in the filter cake to produce silicon dioxide and hydrogen. After the hydrogen is extracted for storage, specific gravity separation takes place via water so that silicon carbide and silicon particles are separated for sorting. Then, solid-liquid separation is performed on the remaining working fluid to separate silicon dioxide (solid) from water and PEG (liquid), before PEG is separated from water. Thus, the useful silicon particles, silicon carbide, silicon dioxide, and PEG are recycled from the filter cake to reduce the total amount of wastes. Moreover, as the side product, hydrogen, is of high commercial value, the method also adds value to recycling.

    Abstract: An apparatus for machining an article (L) in the form of a slab or the like comprises—in addition to a rotary tool (24) associated with a spindle (22)—a nozzle (26) ejecting water at very high pressure. Both the rotary tool and the nozzle are supported by a carriage (20) sliding along a beam (18) in turn sliding along two shoulders (14) in a perpendicular direction. In the working area (12) and above a tank (30) normally filled with water, the article (L) is supported in a horizontal position not only by an interchangeable grid (32; 52), but preferably also by a disposable support (34) which prevent the rotary tool (24) from coming into contact with the grid. The disposable support is periodically replaced.

  • Patent number: 7695348
    Abstract: A bottom wall surface of a blasting chamber of a blasting machine provided with hoppers for recovering an abrasive is formed at a lowest possible position. A cabinet 3 of a blasting machine 1 is compartmentalized at a predetermined position into an upper space and a lower space by mesh members (21, 22) that allow the abrasive to pass therethrough to form a blasting chamber 2 having a bottom wall surface 20 defined by the mesh members (21, 22). Hoppers 10 substantially shaped like an inverted quadrangular pyramid are disposed below the mesh members (21, 22) such that top portions of the hoppers 10 are opened toward the mesh members (21, 22) and that the bottom end of each of the hoppers 10 is made to communicate with suction means, such as a dust collector, through a recovery pipe 30.

  • Patent number: 7465328
    Abstract: An improved dust collector for a power tool is employed. The dust collector includes a body portion, a neck portion and a head portion, wherein the body portion is disposable on the power tool so that during the cutting operation the body portion will receive and direct the air, dust, and debris to the head portion via the neck portion to either be exhausted out or to be collected in a dust collection volume. Preferably, the body portion has a series of openings to allow the user to view the cutting wheel during the cutting operation. The body portion may also have an internal directional member for efficiently directing the flow of air, dust, and debris. The head portion is preferably rotatably connected to the neck portion to allow the user to rotate the head portion to a desired position.

  • Patent number: 7294042
    Abstract: The present invention provides a method of handling abrasive solids materials used in an abrasive cutting procedure which jets a high-pressure abrasive slurry through a nozzle (7) onto a work piece over and/or in a catcher tank (8). This handling method includes catching the used abrasive slurry together with work piece kerf material in the catcher tank, and passing at least some abrasive solids collected in the catcher tank as a slurry to a partitioning apparatus which includes a vibratory sieve (27). The handling method also includes partitioning the slurry with the partitioning apparatus in order to provide at least two solids streams. One of the solid streams passes through the sieve and the other passes across the sieve whilst entrained as a slurry. The handling method further includes passing as a slurry to the nozzle (7) for jetting a pressurised or pressurisable slurry that has partitioned solids stream which has passed through the sieve (27).

  • Patent number: 7282074
    Abstract: An auxiliary dust collection system can be interposed between a sander or other dust producing tool and a vacuum source, e.g., shop vacuum. This auxiliary system has a cyclonic separator connected by a flexible hose to the tool and by another hose to the vacuum source. The cone of the separator is mounted onto the lid of a drum into which the dust precipitates. For a tool that has its own blower, the vacuum source can be omitted, and the air leaving the outlet duct of the separator can be filtered and returned to the ambient. A drop in silencer formed of a sleeve or tube of acoustic foam can be positioned into the inlet side of a filter cartridge following a cyclonic separator. The silencer absorbs a significant fraction of the process noise.

  • Patent number: RE40048
    Abstract: A dust collection system for portable sanding or grinding equipment employs a cyclone separator mounted directly on the tool or machine, with a dust outlet duct at the narrow lower end of the cyclone, and a cartridge air filter mounted on the top of the cyclone. The filter returns the air flow from the machine to the ambient air in the vicinity of the tool. The dust is concentrated in the cyclone, and a small volume air flow then moves the dust through an elongated flexible hose or duct to a remote dust collection station. An air pump at the remote dust collection station provides sufficient air flow to draw the small volume of air plus entrained dust from the tool-mounted cyclonic separator. A cyclonic separator at the remote station separates this dust from the air flow and deposits it in a collection tank or drum.
