The invention involves a nozzle assembly, comprising a nozzle body, and a brush assembly coupled to the nozzle body. The brush assembly includes a threaded fitting and nozzle body coupled thereto. The threaded fitting includes an opening extending therethrough. The nozzle assembly further includes a resilient tube coupled to the threaded fitting. The nozzle assembly is useful for removing dust and debris from openings, such as those formed with a drill and drill bit in concrete.

Disclosed is an apparatus for conveniently and rapidly removing chips from the interior of a pipe by discharging chips with a portion of fluid out of the pipe using the difference between the pressure in the pipe and atmospheric pressure. The apparatus includes a fitting mounted to a region adjacent to a hole bored in a pipe, a sandwich valve coupled to the fitting, a chip-removing adapter mounted above the sandwich valve, a suction tube extending to an inner surface of the pipe through the chip-removing adapter in order to remove chips from the pipe, a vertical moving unit for vertically moving the suction tube, a delivery tube connected to an upper end of the suction tube and configured to deliver the chips to a predetermined place, and a strainer mounted to a distal end of the delivery tube in order to separate the delivered chips from the fluid.

A declogging assembly (20) is configured for use with a suction conduit (10). The suction conduit has a head (14) at a first end (15) and a vacuum tube connection (16) at a second end (17). The assembly includes a body (30). The body defines a first aperture (32), a second aperture (34), and a third aperture (36). The assembly also includes a plug (40) disposed within the body (30). The plug has a surface (42) configured to contact the head (14) of the suction conduit (10) so as to move the plug from a first position, in which the first aperture (32) is in fluid communication with the second aperture (34), to a second position, in which the first aperture (32) is in fluid communication with the third aperture (36). The assembly (20) also includes a biasing member (50) configured to bias the plug into the first position.

The invention relates to a cleaning device for the dry cleaning of a tunnel, comprising a feeding device for feeding a flow of air to a surface being cleaned, wherein the feeding device has an exit opening, through which the flow of air emerges from the feeding device, and a removal device comprising at least one removal pipe with a free end with an opening for suctioning away direct or trash from the surface with the opening of the free end in a first direction. The feeding device is arranged such that the flow of air from the exit opening emerges from the feeding device in a second direction toward the opening of the free end of the removal pipe and impinges on the surface. The first direction is oriented at an angle between 45 and 80 to the second direction.

The current invention is a dryer lint removal system and device that is easily and safe to use. It has a 4 inch elbow that connects to the dryer and is connected to a 4 duct tee. The duct tee is connected to a draft blocker, a flex hose and then to a blowout nozzle. The other side of the tee is connected to a standard exhaust hose. A blower is inserted into the blowout nozzle creating a strong air flow, along with the dryer airflow, pulls the lint from the dryer and also out of the exhaust duct works.
