Изобретение относитс к пневмотранспорту и может быть использовано при ведении бетонных работ в строительстве.The invention relates to pneumatic conveying and can be used in the conduct of concrete work in construction.

Известна установка дл нанесени пневмобетона 1, содержаща герметичныйKnown installation for applying pneumatic concrete 1, containing a sealed

бункер с загрузочным клапаном, механизм выдачи пневмобетона и материальный трубопровод .hopper with feed valve, pneumatic concrete delivery mechanism and material pipeline.

Недостатком известной установки вл етс ненадежность работы с влажным заполнителем . Периодически приходитс очищать ее внутренние поверхности от сло сцементрированной пыли.A disadvantage of the known installation is the unreliability of working with wet aggregate. Periodically, it is necessary to clean its internal surfaces from the layer of cemented dust.

Цель изобретени - повыщение надежности установки в работе.The purpose of the invention is to increase the reliability of the installation in operation.

Дл этого установка снабжена расположенной над загрузочным клапаном и закрепленной одним концом шарнирно на бункере откидной крышкой с отверсти ми, всасывающим трубопроводом и эжектором, жестко закрепленными в отверсти х крышки , кинематически св занной с загрузочным клапаном.For this purpose, the installation is provided with a hinged lid with openings located above the loading valve and hinged at one end on the hopper, a suction pipe and an ejector rigidly fixed in the holes of the lid kinematically connected with the loading valve.

На чертеже показана предлагаема установка , общий вид.The drawing shows the proposed installation, the overall appearance.

Установка содержит герметичный бунке 1 с загрузочным клапаном 2, механизм 3 выдачи смеси через материальный трубопровод 4 и сопло 5 на обрабатываемую поверхность. Выхлопное отверстие сопла перекрываетс пробкой 6. В верхней части бункера расположен загрузочный клапан 2, который св зап гибкими т гами 7 с откидной крышкой 8, расположенной над загрузочным клапаном и закрепленной на шарнире 9. В крышке жестко смонт1фовань всасывающий трубопровод 10, соединенньп с двум гибкими всасывающими рукавами 11 и 12 дл пемента и песка соответ ственно , и патрубок 13 эжектора 14. На диффузор эжектора надет резинотканевый рукав 15.The installation includes a sealed bunker 1 with a loading valve 2, a mechanism 3 for dispensing the mixture through the material pipeline 4 and a nozzle 5 onto the surface to be treated. The exhaust hole of the nozzle is blocked by a stopper 6. In the upper part of the bunker there is a loading valve 2, which is connected with flexible pipes 7 with a hinged lid 8 located above the loading valve and mounted on a hinge 9. The suction pipe 10 is rigidly connected to two flexible suction hoses 11 and 12 for cement and sand, respectively, and nozzle 13 of ejector 14. A rubber-fabric sleeve 15 is put on the ejector diffuser.

Установка работает следующим образом .The installation works as follows.

Claims

The sleeve 15 is retracted to the drainage groove located on the side of the mine working where the installation is located. Include the ejector 14 and for the suction pipe 1O rotate the cover 8 around the hinge 9 in a horizontal position. Zagouuzachy ;; kg: apan 2 at the same time opens the loading opening at the bottom and, turning around the suspension point circle to the bottom, goes into the cavity of the bunker J, In the bukker: there is a vacuum pa 0, J-0.15 kgf / s less than the atmosphere, The fon lid acts as a gigand to; p,: 1 m from the trunk and seals the hopper 3riTG.vi hopper 11 and 12 is piled onto the cement pile ntiCKa. The vacuum in the bun at this. - increases dramatically, and the components of the bothog mixture; sucked by your hands, you sucked the pipeline 10 into the cavity of the scher and fell out there, separated from the transporting air. Separated air through pipe 13 enters the ejector 14 1 in | thrown by them through sleeve 15 2 of the residual ditch, cement dust containing in the exhaust air, at IT / s lg; P1a & t. At the end of the bulge loading, which occurs when the level of the concrete mix rises to the cut-off of the suction pipe 10, the ejector 14 is turned off. The vacuum in the hopper drops, and the cap 8 under the action of the weight of the suction hoses 11, 12 automatically opens the CJiU aeTCHj backfill loading valve 2, which closes the loading opening from below. After stopping the nozzle 5 with the plug 5, the machine is ready to release the mixture through the material pipe 4. Claim of an Invention Apparatus for applying foam concrete to the surface of building structures containing g-sealed buzers with a loading valve, Niexa (R3M pneumatic concrete issuance has a major pipe line that. and t; water; o t for the purpose of elevation.); 1; 1zh gss; ti installation in operation, it is a CV-T / VHU sgkn l-th lid with holes, grew over;; a loading valve; fixed with a hinge end on the bucket, 1) with a suction pipe and an ejector rigidly fixed in the openings of the cover, kinematically connected with the h; - loading valve.
