Недостатком известного устройства вл етс низкое качество смешивани .A disadvantage of the known device is the low quality of mixing.
Целью изобретени вл етс повышение качества смешивани .The aim of the invention is to improve the quality of mixing.
Это достигаетс тем, что смесительна камера снабжена дополнительным эжектором, а лопасти шнекового питател , размещенные в смесительной камере, выполнены эксцентричными , причем оба эжектора св запы с источником сжатого воздуха через двухпозиционный распределитель, смонтированный на полом валу шнекового питател . На внутренней поверхности смесительной камеры выполнены спиральные ребра, направление которых противоположно направлению лопаст м шнекового питател .This is achieved by the fact that the mixing chamber is equipped with an additional ejector, and the blades of the screw feeder placed in the mixing chamber are eccentric, with both of the ejector of the pump with a source of compressed air through a two-position valve mounted on the hollow shaft of the screw feeder. On the inner surface of the mixing chamber there are helical ribs, the direction of which is opposite to the direction of the blades of the auger feeder.
На фиг. 1 показана установка дл набрызгбетона , общий вид; на фиг. 2 - вид по стрелке А на фиг. 1. Установка состоит из бункера 1, шнековогоFIG. 1 shows a setup for sprayed concrete; a general view; in fig. 2 is a view along arrow A in FIG. 1. The installation consists of a hopper 1, auger
питател 2, смесительной камеры 3 со спиральными ребрами 4, трубопровода 5 сжатого воздуха, материального шланга 6, камеры 7 затворени , пасадки 8. На пустотелом валу шнекового питател 2,a feeder 2, a mixing chamber 3 with spiral ribs 4, a pipeline 5 of compressed air, a material hose 6, a shutter chamber 7, a saddle 8. On a hollow shaft of a screw feeder 2,
к которому подключен трубопровод 5 сжатого воздуха, установлен двухпозиционный распределитель 9 сжатого воздуха. К смесительной камере 3 присоединены: к верхней цилиндрической части - эжектор 10, а к нижнейwhich is connected to the pipeline 5 of compressed air, installed two-way valve 9 compressed air. To the mixing chamber 3 are attached: to the upper cylindrical part - the ejector 10, and to the lower
части торцовой стенки - эжектор 11. К валу шнекового питател 2 жестко присоединен электрический шнек 12, наход щийс в смесительной камере 3. Направлени спирали шнекового питател parts of the end wall - an ejector 11. An electric screw 12, located in the mixing chamber 3, is rigidly connected to the shaft of the screw feeder 2. The spiral screw feeder is directed
2 и эксцентричного шнека 12 противоположны направлению спиральных ребер 4 смесительной камеры 3.2 and the eccentric screw 12 are opposite to the direction of the spiral ribs 4 of the mixing chamber 3.
Выходные патрубки двухпозиционного распределител 9 сжатого воздуха присоединены трубопроводом 13 к эжектору 10, а трубопроводом 14 - к эжектору И. Выходной патрубок эжектора 10 соединен трубопроводом 15 с материальным шлангом 6 перед камерой затворени . Материальный шланг 6 с камерой 7 затворени и насадкой 8 подключен к выходному патрубку эжектора 11.The outlet pipes of the on-off distributor 9 of compressed air are connected by pipe 13 to the ejector 10, and pipe 14 to the ejector I. The outlet pipe of the ejector 10 is connected by pipe 15 to the material hose 6 in front of the shut-off chamber. A material hose 6 with a shutter chamber 7 and a nozzle 8 is connected to the outlet of the ejector 11.
Установка дл набрызгбетона работает следующим образом.Installation for sprinkling concrete works as follows.
Приготовленна суха бетонна смесь из бункера 1 шнековым питателем 2 подаетс в смесительную камеру 3. В смесительной камере 3 суха бетонна смесь дополнительно перемешиваетс и эксцентричным шнеком 12 перемеш ,аетс к ее торцовой стенке, и циклично поступает в эжектор 11. Из эжектора 11 суха смесь сжатым воздухом, поступающим от двухпозиционного распределител 9 по трубопроводу 14, направл етс в материальный шланг 6. При верхнем положении эксцентрикового шнека 12 сжатый воздух от трубопровода 5 двухпозиционным распределителем 9 направл етс по трубопроводу 13 в эжектор 10 и производит продувку смесительной камеры 3. При этом мельчайшие взвешенные частицы в жущего и заполнител по трубопроводу 15 направл ютс в материальный шланг 6 перед камерой затворени . В камере затворени смесь затвор етс и направл етс в насадку 8. Сжатый воздух, поступающий в материальный шланг 6 по трубопроводу 15, производит дополнительное перемешивание смеси и обеспечивает оптимальную скорость движени смеси на выходе из насадки 8.The prepared dry concrete mixture from the hopper 1 is fed by a screw feeder 2 into the mixing chamber 3. In the mixing chamber 3 the dry concrete mix is additionally mixed and the eccentric screw 12 mixes to its end wall and enters cyclically into the ejector 11. From the ejector 11 the mixture is compressed dry the air coming from the on-off distributor 9 through the pipeline 14 is directed to the material hose 6. When the eccentric screw 12 is in the upper position, the compressed air from the pipeline 5 by the on-off distributor 9 are on line 13 to the ejector 10 and produces purge the mixing chamber 3. In this case the smallest particles suspended in binder and aggregate on line 15 are directed to the material hose 6 to the mixing chamber. In the mixing chamber, the mixture is closed and directed to the nozzle 8. Compressed air entering the material hose 6 through the conduit 15 produces additional mixing of the mixture and provides the optimum speed of movement of the mixture at the exit of the nozzle 8.
