(54) УСТРОЙСТВО КОНТРОЛЯ ОКОЯКОВАННОСТИ АГЛОМЕРАЦИОННОЙ ШИХТЫ(54) DEVICE FOR MONITORING THE VENTILATION OF THE SINTERING SINTERS

Изобретение -относитс к подготовке шихтовых материалов и может быть использовано дл автоматического контрол окомкованно.сти агломерационной шихты, поступающей на спекание .The invention is related to the preparation of charge materials and can be used to automatically control the pelletized part of the sintering mixture fed to the sintering.

Известно фотометрическое устройство контрол окомкованности агломерационной шихты, выход щей из окомковательного барабана. Измеритель состоит из осветител и фотоприемника, установленных соосно по обе стороны падающего потока шихты, и регистрирующего прибора. Принцип работы измерител состоит в контроле интенсивности светового потока, проход щего сквозь поток падающей шихты Ij.A photometric device for the control of the agglomeration of the sintering mixture coming out of the pelletizing drum is known. The meter consists of an illuminator and a photodetector, installed coaxially on both sides of the incident flow of the charge, and a recording instrument. The principle of operation of the meter is to control the intensity of the light flux passing through the stream of the falling charge Ij.

Недостатком измерител вл етс зависимость его показаний от расхода шихты, поступающей на окомковаОГие . Это св зано с тем, что при посто нной степени окомковани , но при переменном расходе измен етс толщина потока падающей шихты, а следовательно, и интенсивность светового потока, проход щего сквозь него.The disadvantage of the meter is the dependence of its testimony on the flow rate of the charge fed to the OCOM. This is due to the fact that with a constant degree of pelletizing, but with a variable flow rate, the thickness of the incident charge stream, and hence the intensity of the light flux passing through it, changes.

Наиболее близким к изобретению по технической сущности и ожидаемому эффекту вл етс устройство, состо щее из фотодатчика и осветител , уставноленных соосно по обе стороны потокаШИХТЫ, выход щей из окомковательного барабана. Особенностью измерител вл етс то, что с целью устранени вли ни расхода шихты на интенсивность светового потоьса , проход щего сквозь нее, отражательными устройствами отсекаетс The closest to the invention in terms of its technical essence and the expected effect is a device consisting of a photo sensor and an illuminator coaxially mounted on both sides of the CLEANING flow coming out of the pelletizing drum. The peculiarity of the meter is that in order to eliminate the effect of the charge flow on the intensity of the light flux passing through it, the reflective devices are cut off

Недостатком известного устройст15 ва вл етс контакт отражательных устройств с окомкованной шихтой, что приводит к разрушению частиц. Размещение отражательных- устройств в потоке падающей шихты приводит к A disadvantage of the known device is the contact of the reflective devices with the pelletized mixture, which leads to the destruction of the particles. The placement of reflective devices in the incident charge stream leads to

Целью изобретени вл етс повышение точности контрол окомкованности агломерационной шихты за счет устранени вли ни изменений расхода шихты на интенсивность светового потока, проход щего сквозь потокThe aim of the invention is to improve the accuracy of control of the agglomeration charge pelletizedness by eliminating the influence of changes in the charge flow rate on the intensity of the light flux passing through the stream.

Claims

30 falling charge. The goal is achieved by the fact that the device for monitoring the forgings of the sintering mixture, consisting of the source and receiver of the luminous flux, located on both stooons of the falling jet of the charge, the conversion unit and registering the device, is additionally equipped with a flow meter of the charge fed to the pelletizing, and a regulator of the intensity of the luminous flux The meter output is connected to the input of the intensity regulator, and the light source is connected to the output regul. The drawing shows the functional diagram of the arrangement real estate. The scheme includes a flowmeter 1 of the charge entering the pelletizing, a drum 2, flow 3 of the supply charge, regulator 4 intensity of the light flux, light source 5, photodetector 6 registering with the device operates as follows o6 The photoreceiver 6 measures the integral force of the light passing through the falling charge 3 o source 5 Photodetector signal 6 ,. proportional to the brittleness of the charge is recorded by the device 7. When the flow rate of the charge entering the pelletizing drum 2 is changed, the signal from the flow meter 1 is fed to the input 4 of the regulator 4 of the intensity Se oBoro flow. The output signal of the gullet 4 changes the light power of the source 5 so that the integrated light intensity is controlled by the photoreceiver. com b, while the quality of the glass remains unchanged. Thus, the DEVICE controls the eye of the charge of the charge regardless of its approach. Calibration of the registering prior is carried out by taking and analyzing samples of pelletized ichts at various values of it. ashod and granularity. The use of the proposed device for the automatic control and regulation of the pelletization of the sintering mixture makes it possible to improve the quality of the pelletization of the charge, its gas permeability, and consequently, increase the productivity of the sintering machines and reduce fuel consumption. The economic effect from the introduction of one company is 30 thousand rubles. in year.
