摘要： A pneumatic conveyor tube booster valve constructed from an annular tapered rubber sleeve in line with the tube and a sealed pressurized housing surrounding the sleeve portion of the tube. Pressurized gas introduced into the housing escapes past the rubber sleeve when the tube pressure drops below the housing pressure by a predetermined amount and enters the tube in substantially the same direction in which material in the tube is moving. Annular lips on the conveyor tubes supports the rubber sleeve against pressures in the tube.

摘要： A closed circuit pneumatic conveying systems for conveying finely divided solids comprising, in a loop, a pick-up station, separator, air pump, and a return air conduit vented to the atmosphere. A throttle valve is interposed between the return air line and the vent. By adjusting the throttle valve, the rate of pick up can be varied according to demand. The system is useful for unloading semi-free flowing material, e.g. polypropylene flake, from a railroad hopper car.

摘要： A tubular or cylindrical unit that creates a vortex effect with externally supplied pressurized fluid injected angularly within a transport structure is provided. Such a unit is utilized to either accelerate the vacuum and/or air conveyance of liquids, solid aggregates, and gases, reduce the energy required for such materials transport processes, or both. Such a result is achieved through the introduction of pressurized fluid via a plurality of injectors situated evenly around the circumference of the subject tube, pipe, and/or cylinder, and angled uniformly for an even pressure injection of fluid within the conveyance component thereof. In effect, through such injection of pressurized fluid, the overall transport system may be operated at significantly reduced cost while increasing the efficiency of overall vacuum and air conveyance systems simultaneously. The method of utilization of such a device is also encompassed within this invention.

摘要： Method for feeding in and for handling waste material in the channel section of a pneumatic wastes conveying system, in which method waste material or recycleable material is fed into a feed-in container from the input aperture of an input point of a pneumatic pipe transport system for material and onwards into the channel section between the feed-in container and the material conveying pipe, from where the material is conveyed along with the transporting air via the material conveying pipe to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the material is acted upon by the combined effect of suction and replacement air in the channel section by bringing about compression in size in at least a part of the material being conveyed, by means of an impediment arranged between the conveying pipe and the material to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.

摘要： Method for feeding in and for handling waste material in the channel section of a pneumatic wastes conveying system, in which method waste material or recycleable material is fed into a feed-in container (10) from the input aperture (2) of at least two input points (1) of a pneumatic pipe transport system for material and onwards into the channel section (20, 21, 22) between the feed-in container and the material conveying pipe (100), from where the material is conveyed along with the transporting air via the material conveying pipe (100) to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the channel section (20(II), 20(III), 20(IV) . . . (22(II), (22(III), 22(IV)) of at least one second input point is connected to the channel section (20(I), 21(I), 22(I)) of one first input point between the input point (1) and an impeding means (30, 30′), in that in the method at least a part of the material (w1, w2, w3, w4) fed in is acted upon by the combined effect of suction and replacement air in the channel section (20(I), 21(I), 22(I) . . . (20(IV), 21(IV), 22(IV)) by bringing about compression in size in at least a part of the material (w1, w2, w3, w4) being conveyed, by means of an impediment (30) arranged between the conveying pipe (100) and the material (w1, w2, w3, w4) to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.

摘要： Disclosed is a grain conveying apparatus using air, the apparatus efficiently collecting foreign materials while moving grains upward to a position at which the grains are easily fed into a grain processing machine by using the suction force air, and preventing shock so as to prevent damage to the grains. The grain conveying apparatus using air, according to the present invention, comprises: a grain supply hopper for accommodating the grains; a conveyer pipe for guiding the grains supplied from the grain supply hopper and the air flowing in from an external air inlet such that the grains, by means of the air suction force, and the air are moved together; a grain discharge pipe connected to the end of the conveyer pipe; a separation pipe for separating the grains and the foreign materials, the separation pipe comprising a horizontal part connected to the grain discharge pipe and a downwardly curved part for dropping the grains; a rotary valve connected to the lower part of the curved part of the separation pipe so as to discharge the grains in predetermined amounts; an exhaust pipe for discharging the separated foreign materials to the outside; and an air suction means having a ring blower connected to the end of the exhaust pipe so as to suck the air, wherein the front end of the grain discharge pipe is provided to penetrate the lower side of a finishing plate for closing a coupled part of the separation pipe, an inner diameter of the grain discharge pipe and an inner diameter of the separation pipe are formed to be small in a ratio of 0.4 to 0.5:1 such that the internal pressure of the separation pipe is lowered due to a change in the pressure difference, and a cut inclined surface, to be inclined in the direction of the grain conveyer pipe, is formed at the lower part of the front end of the grain discharge pipe, so as to cover the upper part thereof in order not to be influenced by the air discharged to the exhaust pipe connected to the upper side of the separation pipe, and allows the grains to be discharged to the lower side of the horizontal part of the separation pipe having a large inner diameter.
