Description

(54) ЧЕРВЯК ЭКСТРУДЕРА С ПОЗСИНЫМ ОХЛАЖДЕНИЕМ(54) EXTRUDER CERTAIN EXTRUDER COOL

Процесс теплообмена в предлагаемом черв ке осуществл етс  следующим образомThe heat exchange process in the proposed worm is carried out as follows.

Тепловой поток, создаваемый перерабатываемым материалом, от наружной стенки корпуса черв ка отводитс  к пористым элементам 7, насыщенным испар ющейс  жидкостью , в результате чего жидкость с верхних стенок пористых элементов, прилегающих к корпусу , испар етс , и образовавщийс  пар конденсируетс  на нижних стенках пористых элементов , прилегающих к цилиндрической гильзе 5, отдава  ей тепло фазового перехода. Образовавщийс  конденсат под действием капилл рных сил возвращаетс  по пористым стенкам 8 к верхним стенкам пористых элементов, в результате чего цикл испарение - конденсаци  повтор етс . Хладагент, поступающий через сальник Ю по трубкам 3 и 4 отводит тепло от стенки гильзы 5.The heat flux created by the material being processed is diverted from the outer wall of the worm body to the porous elements 7 saturated with the evaporating liquid, causing the liquid from the upper walls of the porous elements adjacent to the case to evaporate and the resulting vapor condenses on the lower walls of the porous elements adjacent to the cylindrical sleeve 5, giving it the heat of the phase transition. The condensate formed under the action of capillary forces returns along the porous walls 8 to the upper walls of the porous elements, as a result of which the evaporation-condensation cycle is repeated. The refrigerant flowing through the omentum Yu through the pipes 3 and 4 removes heat from the wall of the sleeve 5.

Предлагаема  конструкци  черв ка благодар  наличию в изолированных отсеках внутренней его полости пористых элементов, насыщенных испар ющейс  жидкостью, позвол ет интенсифицировать процесс теплопередачи, сократить врем -охлаждени , улучщить динамические характеристики, снизить энергозатраты, повысить качество продукции.The proposed worm design, due to the presence of porous elements in its insulated compartments, saturated with evaporating liquid, makes it possible to intensify the heat transfer process, reduce cooling time, improve dynamic performance, reduce energy consumption, improve product quality.
