Description
В известных способах контроль истечени сыпучего материала недостаточно надежен.In the known methods, monitoring the flow of bulk material is not reliable enough.
По предлагаемому способу скорость истечени сыпучего материала из бункера определ ют по частоте образовани сводов сыпучего материала над выпускным отверстием бункера, регистрируемой с помощью известных датчиков давлени и частотомеров, чем повышаетс надежность контрол истечени сыпучего материала из бункера.According to the proposed method, the flow rate of the bulk material from the bunker is determined by the frequency of formation of bulk material vaults above the outlet hole of the bunker, recorded using known pressure sensors and frequency meters, thus increasing the reliability of monitoring the flow of bulk material from the bunker.
В соответствии с описываемым способом у основани свода 1 (см. чертеж) сыпучего материала над выпускным отверстием 2 бункера 3 устанавливают чувствительный безынерционный датчик 4 давлени любой конструкции, посылаюш,ий импульсы через усилитель 5 в частотомер 6. Скорость истечени сыпучего материала из бункера 5 определ ют по частоте образовани сводов / сыпучего материала над выпускным отверстием 2 бункера 3. Частоту образовани сводов сыпучего материала регистрируют с помощью датчика 4 давлени и частотомера 6.In accordance with the described method, at the base of the dome 1 (see drawing) of the bulk material, a sensitive instantaneous pressure sensor 4 of any design is installed above the outlet 2 of the bunker 3 and sent to the frequency meter 6 through the amplifier 5 to the frequency meter 6. The flow rate of the bulk material out of the bunker 5 is determined based on the frequency of the formation of vaults / bulk material above the outlet opening 2 of the hopper 3. The frequency of formation of the vaults of the bulk material is recorded using pressure sensor 4 and frequency meter 6.
Описанный способ может найти применение дл контрол разности схода материалов в шахтных печах, бункерах, силосах, дл определени начала перехода движени сыпучего материала на неровный ход и подвисание , дл определени количества выпускаемого через отверстие сыпучего материала, а также дл авторегулировки при истечении сыпучего материала из отверсти . Способ проверен в производственных услови х на бункерах и доменной печи Салдинского металлургического завода.The described method can be used to control the difference in the flow of materials in shaft furnaces, bunkers, silos, to determine the beginning of the transition of the movement of bulk material to uneven running and freezing, to determine the amount of bulk material discharged through the hole, as well as to auto-adjust when outflow of bulk material from the hole . The method was tested under production conditions on bunkers and a blast furnace of the Salda metallurgical plant.
Предмет изобретени Subject invention
Способ контрол истечени сыпучего материала из бункера, отличающийс тем, что, с целью повышени надежности контрол , скорость истечени сыпучего материала из бункера определ ют по частоте образовани сводов сыпучего материала над выпускным отверстием бункера, регистрируемой с помощью известных датчиков давлени и частотомеров.A method for monitoring the flow of bulk material from a hopper, characterized in that, in order to increase the reliability of control, the flow rate of the bulk material from the hopper is determined by the frequency of formation of bulk material arches above the outlet of the hopper, detected using known pressure sensors and frequency meters.
