Zusammenfassung: | A Control System for monitoring the flow of air in a high capacity column delivery device, wherein a programmable logic controller, uses one or more sensors for sensing changes in air pressure and an air flow in a system to ensure one or more chute continuously and uniformly discharge a material; the programmable logic controller is connected to the system having; one or more sensors and a compressor which is mechanically connected to the system to supply the air to each chute through an air hose, which is necessary in order to assist the material to travel down a pipes and into the chute and out at a tip of a vibratory probe mechanism; the system further comprises at least one air hose directed downwardly in each chute to prevent any blockage of the material; wherein the programmable logic controller monitors the flow of air and pressure of air in the system through the use of these signals and electronically decides an appropriate reaction by sends a signal to the valve and air hose; when a blockage occurs in the chute, a first signal is sent from the sensor to the programmable logic controller to make adjustments by reducing air flow from a clear chute and diverts more air to a potentially blocked chute which causes an increase in air flow and pressure of air to the potentially blocked chute; and when the blockage is cleared from the chute, a second signal is sent from the sensor to the programmable logic controller to reverse the previous operation and balances the flow of air and pressure of air to each chute.
Linvention concerne un système de commande servant à surveiller le débit dair dun dispositif de distribution de colonne à grande capacité, dans lequel un automate programmable utilise un ou plusieurs détecteurs pour détecter des changements dans la pression de lair et un débit dair dans un système pour sassurer quune ou plusieurs chutes déchargent continuellement et uniformément un matériau; lautomate programmable est connecté au système possédant : un ou plusieurs détecteurs et un compresseur lequel est mécaniquement connecté au système pour alimenter lair à chaque chute à travers un tuyau dair, lequel est nécessaire pour aider le matériau à descendre un tuyau et dans la chute et à lextérieur à une pointe dun mécanisme de sonde vibratoire; le système comprend en outre au moins un tuyau dair dirigé vers le bas dans chaque chute pour empêcher tout blocage du matériau; dans lequel lautomate programmable surveille le débit dair et la pression de la |
