Patent number: 9776814Abstract: Material is removed from a storage silo that has a conveyor outlet, a system for supporting the outlet within the silo comprising removable legs mounted in deployed positions, and a sweep comprising bumpers. The material is extracted until one leg is accessible out of the material, which is then removed from the deployed position thereof. The sweep is then operated to continue extracting more material until one bumper thereof bumps into another of the deployed legs. The sweep is then stopped, and that other leg is also removed from the deployed position thereof. This sequence of operating and stopping the sweep, and removing each deployed leg, is continued for each of the deployed legs until all of the legs are removed from the deployed positions. Each removed leg may be placed onto the supporting system in a stored position thereof. The sweep is then operated to continue extracting more material.Type: GrantFiled: May 6, 2017Date of Patent: October 3, 2017Inventor: Phillip Douglas

Patent number: 5125771Abstract: A portable pneumatic conveyor for various bulk materials includes a hopper which supplies the bulk material to a feed tube. The feed tube is provided with a feed auger which advances the bulk material along the feed tube and into a chamber through which a current of air is passed by way of air inlet and air outlet lines connected to that chamber. The bulk material which is deposited within the chamber is fluidized by the air current and carried by the air current through the air line outlet and along the outlet conveying line to a storage site, such as a silo. In order to prevent air blow-back through the feed tube and alongside the auger, the outlet end of the feed tube is provided with a gate which is intended to at least partly close when the flow of bulk material into the chamber slows down or stops.Type: GrantFiled: April 17, 1991Date of Patent: June 30, 1992Assignee: Blowhard Pneumatic Services, Inc.Inventors: Alvin Herman, Rubien Herman, Ken Bokor

Patent number: 4806056Abstract: Apparatus and a method for delivering materials such as comminuted rubber tires as a secondary fuel to a combustion chamber of a furnace or kiln. A hopper includes a variable speed electric motor-driven screw conveyor, and a control system provides a variable frequency alternating current to the motor of the screw conveyor to deliver a metered amount of fuel from the hopper. A blower and a nozzle assembly may be used to entrain the fuel in a stream of air and carry the fuel to the combustion chamber where it is required. The fuel is delivered in metered quantities in response to the required firing rate of the furnace or kiln. A second metering device provides metered quantities of material which can be carried by the fuel to be taken into a high temperature environment to be decomposed or burned. The apparatus is mounted on a transportable platform.Type: GrantFiled: July 7, 1986Date of Patent: February 21, 1989Assignee: Waste Recovery, Inc.Inventors: Michael W. Rouse, Robert L. Thelen

Patent number: 4344580Abstract: A device for dispensing loose, fibrous material comprising a housing having a reservoir disposed therein for containing the loose fibrous material to be dispensed. The housing has a passageway which extends from the reservoir through which the material is dispensed. At least one auger disc is rotatably mounted in the reservoir approximately adjacent the passageway. A motor or the like is provided to rotate the auger disc such that insulation material encountered by the auger disc is urged toward the passageway. Preferably a bar extends across the reservoir and is spaced from the edge of the auger disc such that as the auger disc rotatingly encounters the fibrous material the bar presents an obstacle to the material which is carried by the auger disc. A centrifugal pump is connected to the passageway by the auger disc. The suction inlet which is connected to the passageway is preferably offset from the center of the housing.Type: GrantFiled: April 14, 1980Date of Patent: August 17, 1982Inventors: Thomas C.
