Abstract: A method and system for metering proppant discharged from a storage container is disclosed. In certain embodiments, a method may comprise loading a known amount of a first proppant type into a storage container, detecting proppant at or adjacent to a discharge outlet of the storage container via one or more sensors coupled to the storage container, operating a metering device at a predetermined speed, wherein the metering device may be coupled to the discharge outlet of the storage container, and wherein the metering device may comprise one or more pockets for receiving the first proppant type. In certain embodiments, the method may further comprise dispensing a known amount of the first proppant type from the storage container via the metering device, wherein an encoder coupled to the metering device may emit pulses during the dispensing. In certain embodiments, the method may further comprise determining an amount of the first proppant type dispensed by at least one pocket of the one or more pockets of the metering device based at least in part on the pulses and determining a relationship between the known amount of the first proppant type dispensed by each pocket and a speed of the metering device.

Abstract: An exemplary diverter valve generally includes a shell, a pipe, and a handle. The shell includes a body extending in a longitudinal direction, a shell inlet port, a shell outlet port, and a positioning slot formed in the body. The pipe is seated in the body for sliding movement in the longitudinal direction, and includes a first passage and a second passage. The handle is connected to the pipe through the positioning slot, and is operable to move the pipe relative to the shell between a first position in which the shell inlet port is connected with the shell outlet port via the first passage, and a second position in which the second passage is connected with the shell inlet port and the shell outlet port is disconnected from the second passage.

Abstract: A system for transferring solid particles from a first environment at a first gas pressure to a second environment at a second gas pressure. The system comprises a first rotary valve having an inlet which is in fluid communication with the first environment, a second rotary valve having an outlet which is in fluid communication with the second environment, and an intermediate housing bounding an intermediate channel, of which an inlet is fluidly connected to an outlet of the first rotary valve and of which an outlet is fluidly connected to an inlet of the second rotary valve. The intermediate channel is fluidly connected to a third environment maintained at a third gas pressure. The third gas pressure is higher than both the first gas pressure and the second gas pressure or lower than both the first gas pressure and the second gas pressure.

Abstract: The present invention is directed to an applicator having an agricultural product conveying system which transfers particulate material from one or more source containers to application equipment on demand, and meters the material at the application equipment. The conveying system includes an inline metering system including a number of metering devices associated with each compartment of a particulate material tank on the applicator to meter the particulate material disposed within each compartment. The individual metering devices include gates to initially enable the particulate material from a compartment to enter the metering device, and a rotary metering shaft to meter the flow of the particulate material into the conduits while limiting the passage of pressurized air through the metering device and into the compartment. The individual metering devices also include individual motors to control the operation of the metering devices independently from one another that can allow with sectional control and turning compensation.
