摘要:
In a pneumatic conveyor comprising multiple, assembled conveyor sections, a conveyor section provides a curved conveyor path with a plenum through which pressurized air is delivered. The conveyor section includes a top plate including a series of apertures extending therethrough for delivering pressurized air from the plenum to an upper surface of the top plate. The apertures are arranged and configured to direct the pressurized air to move an article along the top plate in a conveying direction. A bottom plate is located beneath the top plate. A first stack of vertically aligned, individual strips are clamped together between the top plate and the bottom plate to define a first sidewall of the plenum. A second stack of vertically aligned, individual strips are clamped together between the top plate and the bottom plate to define a second sidewall of the plenum.

The present invention is directed to an Installation for feeding a plurality of loads, e.g. cells of aluminum melting furnaces, with a bulk material such as pulverized aluminum oxide. The installation includes a silo for the bulk material. The silo includes a pressure vessel or pump delivering machinery which is connected with a conveying line. A plurality of receiving vessels are connected with the conveying line via valves in the vicinity of the furnace loads. The receiving vessels are connected to the plurality of loads of the furnaces by at least one pneumatic conveying chute or pneumatic pipe channel. Each conveying chute or pipe channel includes at least one discharge per load.

A material feed apparatus 34 for influencing the travel properties of a feed stream of material 42 moving between a pulverizer 14 and a furnace 12 includes a feed path 36 passing through an upstream passage periphery UPZ. The feed path 36 includes one duct 44A having a branch entry 66A and another branch duct 44C having a branch entry 66C both downstream of the upstream passage periphery UPZ through which the feed stream of the material 42 travels in two segregated portions. A Y-axis drive assembly 58 and the X-axis drive assembly 62 move the nozzle 52 relative to the reference axis RA, whereupon the upstream passage periphery UPZ moves relative to the reference axis RA such that the travel properties of the one portion of material in the one branch duct 44A are different than its travel properties before the movement of the upstream passage periphery UPZ.

Process for radial distribution of fluid into a fluid mass wherein fluid is radially conveyed within and isolated from the fluid mass and discharged via a plurality of distribution points located radially in the fluid mass.
摘要:
A process for continuous conveying of a fine-grained and/or pulverized solid to two or more target points by a conveying medium, e.g. gas. The solid is charged into a distribution vessel and from there to several target points by respective supply lines each at a desired target flow rate intended for target point. The target flow rate for each target point is divided into at least two partial target flow rates from the distribution vessel via separate partial supply lines. The partial target flow rates are reunited at the respective target points at the latest. To adjust the target flow rate at a target point at a specific level, individual partial supply lines leading to this target point are alternatively kept shut-off or open.
摘要:
Apparatus for cooperation with an associated coal burning furnace which includes a Y-shaped distributor body having one inlet and first and second outlets and a splitter disposed in the body for dividing flow between the first and second outlets. The splitter has a generally V-shaped contour and the splitter comprises a base on the housing and a liner assembly mounted on the base. In some forms of the invention the liner assembly has a surface that is harder than the surface of the housing and the housing includes a removable access panel. The access panel may be dimensioned and configured to allow passage of the liner assembly into and out of the housing. The liner assembly may comprise an outer shell having at least some foamed material disposed therein and may include anchoring means disposed in the foamed material. In other forms of the invention the anchoring means may be dimensioned and configured for engagement with the housing to anchor the liner assembly against the foamed material and the base may include a mounting surface that is generally planar and disposed in generally normal relationship to the direction of flow into the inlet. The base may have diverging sides dimensioned and configured for engaging the liner assembly and the anchoring means may include a plurality of eyebolts.

The subject flow proportioner device has a pivoting target plate opposite an inlet and between a pair of axially aligned exit ports. Product is introduced through a flow shaping inlet and strikes a profiled target on the plate forming a cushion and diverting the subsequent product between the outlets.
摘要:
A method for drying, crushing and distribution of solid fuel for a solid fuel boiler, for example a fluidized bed boiler. The method is characterized in that moist fuel is crushed and dried by intermixing gas and/or ash, and that the fuel is set in motion, for example in a cyclone together with gas, the fuel thus being divided into several sub-flows for feeding into the boiler at different points.
摘要:
A pneumatic transportation system for particulate material, such as powdered or granular materials, with a switching valve (7) for selection of different transport paths within the transportation system. The valve includes a turnable rotor (15) with a bore or a compartment (23), the inner part of which constitutes a blind space for forming an erosion-preventing cushion (26) of powder. An upstream conduit (6) is connected to the valve housing (14) opposite to the blind space of the compartment (23). In dependence on the position of the rotor (15), the compartment (23) or a channel (24) adjacent to this forms a connection to any one of several downstream conduits (20, 21) connected to the valve housing (14).
