The device operates as follows.

Разгрузка каждой камеры установки сухого тушения кокса осуществляется постоянными порциями. Расход кокса каждой камеры определяют путем измерения . интервала между двумя последни· 25 ми разгрузками и вычисления обратно пропорциональной величины с учетом величины порции кокса.

The coke consumption of each chamber is determined by measurement. the interval between the last two · 25 mi unloadings and the calculation of the inversely proportional value taking into account the size of the portion of coke. To reduce the delay in the operation of the device in case of a decrease in coke consumption, i.e. increasing the interval from the last unloading to the current moment in time, the flow rate is calculated by measuring the interval from the last unloading to the current moment and calculating _3J inversely proportional to the coke.

Завершение разгрузки каждой порции сопровождается выдачей датчиком 7, импульса,.которым производится пере- «о пись содержимого интегратора 1 через блок 4 в блок 8, а также через время, определенное элементом 3, сброс содержимого интегратора 1. Содержимое интегратора Г в момент переписи 45 соответствует количеству временных меток генератора 2, т.е. пропорционально времени между двумя последними разгрузками. После сброса интегратора 1 начинается очередной цикл от- ₅₀счета интервала. Если текущее значение интегратора 1 меньше содержимого блока 8, то блок 5 формирует управляющий сигнал для коммутатора 6/ по koto^jрому на счетчик 9 через комму)а тор 6 _SJпоступает содержимое блока 8.

Content of integrator G at the time of the census 45 corresponds to the number of time stamps of the generator 2, i.e. in proportion to the time between the last two unloadings. After resetting the integrator 1, the next cycle starts from the _50th interval count. If the current value of the integrator 1 is less than the contents of the unit 8, the unit 5 generates a control signal for the switch 6 / by koto ^j rum on counter 9 through the commutator) and 6 Torr _SJ supplied contents block 8.

(5) DEVICE FOR REGISTRATION OF COX COSTS ON DRY EXTINGUISHING INSTALLATION The invention relates to automation of the control of a coke dry quenching plant and can be used in the coking industry. A device for measuring the performance of periodically operating equipment is known, which contains a hydraulic resistance and a storage medium connected to a pipeline connecting the pump with the consumer l}. The device is intended to measure the performance of periodically operating equipment using a liquid medium, and cannot be used for equipment with friable material. The closest technical solution to the invention is a device for measuring the flow rate of bulk materials for scraper and screw conveyors containing a gating unit, an integrator, a counting unit. The disadvantage of this device is the inability to measure the flow rate of bulk materials with a varying interval between adjacent portions of the material and large delayed output signal associated with the need to sum the signals to a certain value before calculating the next value of the expenditure. The purpose of the invention is to expand the functionality of the device and increase the speed of the device. The goal is achieved by including a Delay unit, a pulse generator, a memory unit, a comparison unit and a switch, to a device for recording coke consumption on a dry extinguishing plant containing a flow sensor, a counter and an integrator whose output is connected to the first input of the gating unit moreover, the output of the flow sensor is connected via an 395 valuable Delay elements, an integrator, a gating unit, a memory unit, a comparison unit and a switch with a counter input and with a second input of the gating unit, output g The pulse generator is connected to the second input of the integrator, the output of which is connected to the second inputs of the comparator unit and the switch connected by the third device to the memory unit. The drawing shows the functional scheme of the device. The device contains an integrator 1, a generator of 2 pulses, a Delay element 3, a strobe block A, a comparison block 5, a switch 6, a flow sensor 7, a memory block 8 and a counter 9 The device operates as follows. Unloading of each chamber of the coke dry quenching plant is carried out in constant portions. The coke consumption of each chamber is determined by measuring the interval between the last two unloadings and calculating the inverse proportion to the size of the coke portion. In order to reduce the delay in the operation of the device in case of a decrease in coke consumption, i.e. increasing the interval from the last unloading to the current point in time, the flow rate is calculated by measuring the interval from the last unloading to the current moment and calculating the inversely proportional value c - taking into account the value of a portion of coke. Completion of unloading of each portion is completed by issuing a pulse sensor, which records the contents of integrator 1 through block k to block 8, and also after a time determined by element 3, the contents of integrator 1 are reset. The contents of integrator 1 at the time of the census correspond to the number of time stamps of the generator 2, those. proportional to the time between the last two discharges. After resetting the integrator of torus 1, the next interval reference cycle begins. If the current value of integrator 1 is less than the contents of block 8, then block 5 generates the control signal for switch 6, which sends the contents of block B through commutator 6 as soon as the current value of the integrator becomes greater than the contents of block 8 , block 5 switches switch 6 to the passage of information from ViHTerpaTor 1 to counter 9. Counter 9 calculates the current value of coke consumption for one dry extinguishing chamber. Thus, the device continuously measures the current coke consumption of the dry extinguishing chamber, the maximum time delay being the well value of the interval between the last two unloadings. The implementation of the proposed device will ensure automatic monitoring of the performance of the coke dry quenching plant, which is necessary for the qualitative management of the technological mode of the extinguishing process (parameter adjustment, control control), which will give an economic effect of about 40 thousand rubles. on one installation of six cameras.
