Description

Устройства дл  определени  газопроницаемости шихты по расходу воздуха, просасываемого через первую вакуум-камеру спекат тьной машины , известны.Devices for determining the gas permeability of the charge according to the flow rate of air drawn through the first vacuum chamber of the sintering machine are known.

Новизна предлагаемого устройства состоит в том, что оно, с целью точного автоматического измерени  газопроницаемости сло  шихты, выполнено в виде измерительной вакуум-камеры («зонта) с расходомером и эксгаустером, установленной на агломерационной ленте, над слоем шихты между барабанным питателем и зажигательным горном.The novelty of the proposed device is that it, in order to accurately measure the gas permeability of the batch, is made in the form of a measuring vacuum chamber (“umbrella”) with a flow meter and an exhauster installed on the sintering belt, above the charge layer between the drum feeder and the incendiary mountain.

Установка этого устройства, в отличие от прежних, не св зана с уменьшением полезной площадки спекательной машины, так как зажигательный горн не требуетс  передвигать на вторую вакуум-камеру.The installation of this device, unlike the previous ones, is not associated with a decrease in the useful area of the sintering machine, since the incendiary horn is not required to be moved to the second vacuum chamber.

На фиг. 1 изображен общий вид устройства; на фиг. 2-деталь вакуум-камеры («зонта).FIG. 1 shows a general view of the device; in fig. 2-part vacuum chamber (“umbrella”).

Устройство представл ет собой вакуум-камеру в виде «зонта / особой формы, свободно поко щуюс  иа шихте 2 между фартуком барабанного питател  3 и фронтальной частью зажигательного горна 4.The device is a vacuum chamber in the form of an “umbrella / special shape, freely resting on charge 2 between the apron of the drum feeder 3 and the frontal part of the incendiary horn 4.

Эксгаустер 5 создает в пространстве, ограниченном зонтом / и щихтой 2, вакуум 700-1200 мм вод. ст., благодар  чему воздух просасываетс  через весь слой щихты под «зонт / и по трубопроводу 6 через расходомер 7 выбрасываетс  в атмосферу.Exhauster 5 creates in the space bounded by an umbrella / and lean 2, a vacuum of 700-1200 mm of water. Due to this, air is sucked through the entire layer of the furnace under the umbrella / and through line 6 through the flow meter 7 is released into the atmosphere.

В зависимости от влажности шихты, газопроницаемость ее измен етс  в широких пределах, а следовательно, и расход просасываемого воздуха, измер емый расходомером.Depending on the moisture content of the charge, its gas permeability varies over a wide range, and, consequently, the flow of sucked air measured by the flow meter.

Необходимое уплотнение между «зонтом / и поверхностью шихтыThe necessary seal between the "umbrella / and the surface of the charge
