  • Patent number: 9637880
    Abstract: A snow melting vehicle includes a receptacle for receiving a snow load to be melted inside the receptacle into meltwater and a debris collecting system for moving the debris fallen to the bottom of the receptacle into a collecting chamber disposed adjacent the receptacle. A debris lifting system is also provided for raising the debris from the collecting chamber to a position above the meltwater filling the collecting chamber, whereby the meltwater is substantially drained before the debris is gravity discharged outside the snow melting vehicle.

  • Patent number: 8640687
    Abstract: An upright induction chamber (100) is positioned within a melting tank (24) of a snow melting apparatus (20). The melting tank is filled with melting water. Shredded snow from a hopper assembly (22) is introduced into the upper end of the induction chamber along with heated melting water, to be mixed by an impeller fan pump (110) that is operated to force the melting water at sufficient speed through the induction chamber to overcome the buoyancy of the snow, thereby facilitating uniform distribution of the snow across the induction chamber and good mixing of the snow with the melting water. A portion of the liquid composed of the melted snow and melting water from the induction chamber is expelled from the melting tank, and a portion of the liquid from the induction chamber passes through a heat exchanger (34) positioned within the heating tank to be heated thereby and then re-introduced into the upper portion of the induction chamber.

  • Patent number: 7979170
    Abstract: A snow removal system wherein snow removers located in remote locations can be monitored and controlled at a computing device. Data collected by sensors on the snow removal unit or data collected from a secondary source can be used to control the operation of the snow removers. In one embodiment, data regarding whether it is snowing at a particular location can be collected by moister sensors on the snow removal device and verified by on-line contemporaneous weather reports corresponding to the same location.

  • Patent number: 7594627
    Abstract: Methods and devices for deicing aircraft and other snow or ice covered surfaces. The invention is based on warm moisture-laden air or steam that can be released over the surface to be thawed. The device consists of three components: a hot water or steam boiler with an associated pump; a plenum for heating and humidifying air; and a delivery unit or head that brings the moisture-laden air or steam into contact with the surface to be de-iced or thawed. Various delivery heads are also described.

  • Publication number: 20080295364
    Abstract: A fluid shovel apparatus that pushes and lifts loose material such as snow, leaves, sand, dirt, grass clippings, mulch, or the like. The present invention includes at least one fluid exhaust port extending through a blade. Pressurized fluid is ejected through the at least one fluid exhaust port extending through the blade and ejects towards loose material. The loose material floats on a cushion of pressurized fluid that forms between the blade and the loose material. The loose material is pushed away from the blade and is lifted in an upward direction. Additionally, the fluid shovel apparatus may further include a soft pad and an ice scraper blade to assist in removing material from a surface of a motor vehicle. Additionally, the fluid shovel apparatus may be used to deliver a fire suppressant pressurized fluid upon a material that is burning. Additionally, the fluid shovel apparatus may be used to clear snow from railroad train tracks ahead of a railroad train car.

  • Patent number: 6305105
    Abstract: An apparatus for disposing of snow that is deposited on a surface. The apparatus includes a removal mechanism that removes the snow from the surface and guides the snow into the apparatus. A first chamber is connected to the removal mechanism. The first chamber has a first aperture that permits fluid to be injected into the snow to aid in melting the snow. A second chamber is connected to the first chamber. The second chamber has an agitating device that moves the snow and separates the snow into a slurry to further melt the snow. A third chamber is connected to the second chamber and is configured to store the melted snow. A disposal mechanism is provided that removes the excess snow from the third chamber. Snow is removed from the surface by the removal mechanism and is melted as it moves through the first chamber, the second chamber, and the third chamber.

  • Patent number: 5365681
    Abstract: A vehicle for snow removal has a conveyor belt for transporting shovelled snow from a front end shovel up to a collection load box, above which the snow is melted by a plurality of heat sources for deposit into the collection load box. A pump recirculates melted snow water through a pair of parallel conduit pipes, which pipes are adjacent to the plurality of heat sources. As a result the recirculated water is reheated and the resulting warm water is discharged upon the front end shovel to commence the melting of the incoming, shovelled snow.
