  • Patent number: 11839181
    Abstract: A grain handling system having an air system is presented that is capable of automatically detecting and clearing a plug in a tube of an air system using a central controller, an air pressure sensor, a dynamic pressure relief valve and a variable frequency drive connected to and controlling a blower motor. When a plug is detected, the central controller stops the flow of grain into the tube and ramps up the output of the blower motor to full capacity. Thereafter, the central controller performs an unplugging routine by opening and closing the dynamic pressure relief valve causing surges of air to impact the plug either breaking up the plug or bumping the plug along the tube until it clears. Once the plug clears, the central controller resumes normal operation.

  • Publication number: 20110299943
    Abstract: A system provides pneumatic conveyance of granular materials, for example, grain or other dry, loose commodities. They system conveys the commodity from a first piece of equipment, for example a grain dryer, to a second piece of equipment, for example, a grain bin. A variable speed blower motor is mounted to drive air through a transport pipe, and the blower motor speed is controlled by a processor and software to provide a desired pressure to efficiently move the commodity based on the rate of discharge into the transport pipe, while minimizing wasted energy or damage to the commodity that is often experienced when more than the required pressure is provided by a blower motor. Parameters used in determining the blower motor speed may include the gauge pressure measured in the transport pipe, the rate of discharge of commodity into the transport pipe, and the blower motor current or power.

  • Publication number: 20110270440
    Abstract: Provided herein are systems and methods for use in controlling a translocation process of a pneumatic tube system in order to reduce the amount of energy transferred from the tube system to a pneumatic carrier and, hence, its contents. Generally, these utilities entail identifying and/or reducing forces applied to a pneumatic carrier traveling through a travel path within a pneumatic tube system. The systems and method disposed herein allow for varying the velocity of a pneumatic carrier as it passes through a travel path of the pneumatic system. Such varying of the velocity allows for reducing the total forces applied to the pneumatic carrier during passage through the system. In one arrangement, the power output of a power source connected to a compressor device is altered to vary the velocity of pneumatic carries in the system.

  • Patent number: 7740423
    Abstract: A vacuum modulating air control valve includes a valve body with air intake ports, an output port, and a valve throat. A valve member is slidably mounted within the valve body between open positions relative to the valve throat and a closed position, to which the valve member is urged by a valve spring. A pneumatic cylinder has a piston forming a vacuum chamber and has a piston rod connected to the valve member. The output port is connected to a feedpoint of a vacuum conveying system, and the vacuum chamber is connected to a vacuum line communicating with the vacuum conveying system. A vacuum level within the vacuum chamber retracts the valve member from the throat, thereby admitting ambient air into the vacuum conveying system to control a material-to-air ratio within the system.

In the method, at least one sensor (12) is provided. This has a sensing face (42), and the sensor is mounted at a predetermined position along the length of the pipeline such that the sensing face is flush with the invert of the pipeline at that position. The sensor is calibrated to provide output signals related to the velocity of the slurry at the invert. The operation of the pump and/or the density of the slurry are then controlled in response to the output signals from the sensor. Other aspects of the invention relate to the apparatus and to a slurry pipeline control system incorporating the apparatus and in which the method is implemented.

  • Patent number: 7524146
    Abstract: A system is provided for distributing particulate matter. The system includes at least two conduits, each conduit extending from a common first position adjacent a source of particulate matter to a second position. The pressure differential between the first and second positions is substantially the same for each conduit. A pressurized fluid conveys particulate matter through the at least two conduits. A device measures mass flow of particulate matter in each of the at least two conduits. A controller is in communication with the device that provides additional pressurized fluid to each conduit having a solids ratio greater than the desired solids ratio of the at least two conduits in response to a measured mass flow rate to balance (or to preferentially bias) mass flow of particulate matter through each of the at least two conduits.
