Description
(5) УСТРОЙСТВО ДЛЯ ВАКУУМИРОВАНИЯ ПОЛЫХ (5) DEVICE FOR HOLLOW VACUUMING
II
Изобретение относитс к изготовлению бетонных и железобетонных изделий в строительстве и может быть использовано при изготовлении железобетонных труб.The invention relates to the manufacture of concrete and reinforced concrete products in construction and can be used in the manufacture of reinforced concrete pipes.
Известен вакуум-щит, содержащий кольцевую оболочку из фильтровальной ткани и гибкий каркас из воздухонепроницаемого материала, образующий с фильтровальной тканью вакуум-полость п.Known vacuum shield containing an annular membrane of filter cloth and a flexible frame of an airtight material, forming a vacuum cavity with filter cloth.
Наиболее близким к предлагаемому вл етс устройство дл вакуумировани полых изделий, содержащее кольцевую оболочку из фильтровальной ткани и каркас, размещенный в ней с образованием между последним и оболочкой полости, соединенной патрубками дл подвода вакуума и сжатого воздуха 12.Closest to the present invention is a device for evacuating hollow articles, comprising an annular casing of filter cloth and a frame placed therein to form a cavity between the latter and the casing connected by nozzles for supplying vacuum and compressed air 12.
Недостатком этих устройств вл етс неравномерность отсоса влаги и воздуха. ИЗДЕЛИЙThe disadvantage of these devices is the uneven suction of moisture and air. PRODUCTS
Цель изобретени - повышение качества издели за счет равномерного удалени влаги по всей поверхности издели .The purpose of the invention is to improve the quality of the product by uniformly removing moisture over the entire surface of the product.
Указанна цель достигаетс тем, что устройство дл вакуумировани полых изделий, содержащее кольцевую оболочку из фильтровальной ткани и каркас, размещенный в ней с образованием между последним и оболочкой полости, соединенной патрубками дл подключени к вакуум-системе и подачи сжатого воздуха, снабжено прикрепленными к внешней стороне каркаса This goal is achieved by having a device for evacuating hollow articles comprising an annular filter fabric shell and a frame placed therein to form a cavity between the latter and the cavity shell connected by nozzles for connecting to a vacuum system and supplying compressed air. frame
15 продольными ребрами с углублени ми, в которых расположены по спирали нагнетательный и отсасывающий трубопроводы из эластичного материала, причем нагнетательный трубопровод 15 longitudinal ribs with recesses, in which the injection and suction pipelines of elastic material are arranged in a spiral, with the discharge pipe
