Description
Изобретение относится к устройствам для хранения и выдачи сыпучих материалов, склонных к сводообразованию, и может быть использовано в угольной, соляной и других отраслях народного хозяйства.The invention relates to devices for storage and distribution of bulk materials, prone to arch formation, and can be used in coal, salt and other sectors of the economy.
Цель изобретения — повышение надеж- 5 ности работы за счет упрощения конструкции и использования энергии положения сыпучего материала.The purpose of the invention - increase the reliability 5 of papers, by simplifying the design and use of the energy position of the bulk material.
На фиг.1 представлена схема бункера; на фиг.2 — поперечное сечение, корпус бун- ю кера.Figure 1 presents the diagram of the hopper; figure 2 is a cross-section, the body of the bunyu kera.
Бункер состоит из корпуса 1, закрепленного верхней частью 2, и приспособления 3 для предотвращения сводообразования.The hopper consists of a housing 1, secured by the upper part 2, and a device 3 to prevent arching.
Приспособление 3 содержит выступ 4, ра- 15 му 5, охватывающую нижнюю часть корпуса 1 и коническую горловину 6, размещенную внутри этой нижней части. Выступы 4 укреплены на рычагах 7, установленных на гори-. зонтальных осях 8, закрепленных на раме 5. 2θ Рычаги 7 стремятся повернуться навстречу друг другу под действием пружин 9 растяжения. Выступы 4 имеют криволинейные рабочие поверхности 10. В среднем сечении элемента криволинейные рабочие поверхности 10 имеют гиперболическую форму. Бун- 25 кер примыкает, например, к шнековому питателю 11. Поворот рычагов 7 навстречу друг другу ограничивается упорами 12, расположенными на раме 5. Разгрузочное устье бункера уплотнено фартуком 13. Корпус бункера выполнен из упругого эластичного ма- 30 териала, например тонколистовой пружиня: щей стали.The device 3 comprises a protrusion 4, a frame 15, covering the lower part of the housing 1 and a conical neck 6, located inside this lower part. The protrusions 4 are mounted on levers 7 mounted on a horizontal. the axial axes 8, mounted on the frame 5. 2 θ The levers 7 tend to rotate towards each other under the action of tension springs 9. The protrusions 4 have curved working surfaces 10. In the middle section of the element, the curved working surfaces 10 have a hyperbolic shape. The bunker 25 ker is adjacent, for example, to the screw feeder 11. The rotation of the levers 7 towards each other is limited by the stops 12 located on the frame 5. The discharge mouth of the hopper is sealed with an apron 13. The hopper body is made of elastic material 30, for example a leaf spring: of steel.
Бункер работает следующим образом.The hopper operates as follows.
В исходном положении рычаги 7, стремясь повернуться навстречу друг другу, деформируют корпус 1 бункера, придавая ему слож- 35 ное напряженное состояние. Характерные участки корпуса 1 имеют по образующим гиперболическую форму. В случае нормального течения материала по бункеру его кор пус 1 и рычаги 7 находятся в статическом первоначальном положении. В случае задержки материала в застойной зоне (образование свода) возрастает боковое давление на стенки корпуса бункера Ν. Эти усилия создают момент XNh, преодолевающий сопротивление пружин 9 и направленный в сторону от бункера, что приводит к увеличению живого сечения корпуса 1 в застойной зоне и автоматическому обрушению свода. Указанная система сводообрушения может работать в автоколебательном режиме.In the initial position, the levers 7, trying to turn towards each other, deform the hopper body 1, giving it a complex stress state. The characteristic sections of the housing 1 are hyperbolic in shape. In the case of a normal flow of material along the hopper, its housing 1 and levers 7 are in a static initial position. In the event of material retention in the stagnant zone (arch formation), the lateral pressure on the walls of the hopper body унк increases. These efforts create the moment XNh, overcoming the resistance of the springs 9 and directed away from the hopper, which leads to an increase in the living section of the housing 1 in the stagnant zone and automatic collapse of the arch. The specified system collapse can work in self-oscillating mode.
Таким образом, применение податливых стенок бункера, находящихся под воздействием подпружиненных рычагов 7, препятствует зависанию, т. е. предотвращает застойное сводообразование сыпучего материала.Thus, the use of ductile walls of the hopper, which are under the influence of spring levers 7, prevents freezing, that is, prevents stagnant consolidation of bulk material.
Использование устройство позволит снизить энергопотребление и повысить надежность работы.Using the device will reduce energy consumption and increase reliability.
