Abstract
Изобретение относитс к горной промышленности и может быть использовано дл проветривани тупиковых горных выработок . Цель изобретени - повышение эффективности работы устройства за счет повышени степени сжимани выходного отверсти трубопровода Дл этого приспособление дл ежи. t- и трубопровода снабжают штуцером , дл подвода сжатого воздуха , а само око с змещаетс в выходном сечении гибкого трубопровода (ГТП) 1 вдоль вертикальной оси симметрии выходного сечени ГТП 1 и выполнено в виде трубчатого пр молинейного коллектора (ТП К) 4 с торцовыми заглушками 6. Верхн заглушка 6 соединена с подвеской 3 и на ней закреплен штуцер 7. На боковой поверхности ТПК 4 выполнены щели, выходное сечение которых расположено в п носкости, параллельной выходному сечению ГТП 1. В результате за с°ег подачи сжатого воздуха через штуцер 7 в ТПК4 сжатый воздух создает направленный воздушный поток, который прм выключенном вентил торе, т.е. перед началом взрывных рг -, создает перепад давлени , под действ, ч которого гибкий ГТП 1 плотно прижимайс к стенкам 4, Выходное сечение 1 при этом перекоываетс , что не дает разрешить ГТП 1 при подходе к. нему ударной волны. 1 з п. ф-лы, 5 ил. сл сThe invention relates to the mining industry and can be used for aerating dead-end mine workings. The purpose of the invention is to increase the efficiency of the device by increasing the degree of compression of the outlet of the pipeline. For this purpose, a device for hedgehogs. The t- and pipelines are provided with a fitting for supplying compressed air, and the eye itself is placed in the outlet section of the flexible pipeline (GTP) 1 along the vertical axis of symmetry of the output section of GTP 1 and is made in the form of a tubular rectilinear collector (TP K) 4 with end caps 6. The upper plug 6 is connected to the suspension 3 and a fitting 7 is fixed on it. On the side surface of TPK 4, slots are made, the output section of which is located in the plane parallel to the output section of the GTP 1. As a result, with s &tutser 7 TPK4 compressed air creates a directed air flow, which fan is switched off prm torus, i.e. before the start of explosive rg -, it creates a pressure drop, under the action of which flexible gtr 1 tightly pressed against the walls 4, Output section 1 at the same time is repacked, which does not allow the gtr 1 to be allowed when the shock wave approaches it. 1 з п. Ф-лы, 5 Il. cl
