Abstract: FIELD: processes and equipment for neutralizing solid domestic waste materials. SUBSTANCE: method for aeration of dumps and polygons for concealing solid domestic waste materials by providing air circulation in dump body is realized due to using system of successively connected gas-permeable inflow, transporting and exhaust tubes arranged in dump body and heated by means of heat separated in dump body. Air is discharged to atmosphere from exhaust tubes at level higher than that of air taking to inflow tubes. Aeration system includes tubes for supplying air to dump body; said tube system includes successively connected inclined inflow tubes, horizontal transportation perforated tubes and vertical exhaust tubes. Outlet opening of exhaust tubes is arranged at level higher than taking opening of inflow tubes. Invention provides methane yield increased by 8 - 10 times in comparison with non-aerated dumps.

Granted: 2005-05-20
Abstract: Изобретение относится к устройствам для срезания нежелательной древесно-кустарниковой растительности, распространенной вдоль каналов, дорог, линий электропередачи, а более конкретно к кусторезам с рабочими органами в виде дисковых пил. Кусторез включает базовый трактор, навесную раму, навешиваемую на систему навески, телескопическую стрелу с телескопом, выдвигаемым гидроцилиндром, рабочий орган в виде дисковой пилы, закрепленной на конце телескопа. Шарнирное крепление телескопической стрелы к навесной раме позволяет осуществлять ей маятниковые рабочие движения с помощью гидроцилиндра и двух рычагов. Привод дискового пильного рабочего органа осуществляется от вала отбора мощности через телескопическую карданную передачу, редуктор и ременную передачу, включающую ремень со шкивами. При втягивании гидроцилиндра телескопического устройства постоянное натяжение ремня осуществляется через натяжное устройство, выполненное в виде рычагов с закрепленными на концах натяжными роликами, толкателей, связанных с гидроцилиндром, и ползунов, перемещаемых по рычагам. Кусторез дополнительно снабжен двумя автономными системами подачи арборицидной смеси в зону резания, первая из которых включает толкающий брус, выполненный полым для заполнения данной смесью через подводящую ее магистраль. Он закрепляется шарнирно на навесной раме и имеет пружину. Внутри бруса для подачи арборицидной смеси на образующиеся после срезания древесной растительности пни устанавливаются клапаны, содержащие толкатели, пластины, возвратные пружины и сопла. При этом для транспортирования смеси в зону резания (к пням) на пиле выполнены отводящие канавки и сквозные отверстия, расположенные рядом с зубьями пилы. Вторая автономная система подачи арборицидной смеси обеспечивает ее транспортирование по магистрали через вращающееся соединение, проточку в валу и транспортирующие каналы в пиле к соплам, расположенным рядом с зубьями. Данная система включает клапан, содержащий корпус и установленный внутри шток, связанный, в свою очередь, с толкающим брусом, а также поршень и возвратные пружинные элементы. Вторая система может служить как для подачи смеси на пни при воздействии срезаемого ствола на толкающий брус, так и для непрерывной подачи при равномерном ее распределении на очищаемой от древесно-кустарниковой растительности площади путем постоянного включения данного устройства за счет заполнения надпоршневого пространства А через магистраль рабочей жидкостью гидросистемы трактора. Для разделения магистралей установлен кран. Изобретение обеспечивает возможности подачи дисковой пилы без боковых нагружений и защемлений рабочего органа, а также срезания древесно-кустарниковой растительности дисковой пилой с одновременной подачей в зону резания арборицидной смеси непосредственно при воздействии толкающего бруса на срезаемую растительность и расширение технологических возможностей кустореза путем изменения радиуса его действия. 4 ил.
