Description

( ЭРЛИФТНАЯ УСТАНОВКА(AIRLIFT INSTALLATION

: . :.

Изобретение относитс к насосо строению, в частности к конструкции эрлифтных установок дл транспортировани золошлаковых материалов йа электростанци х, и может примен тьс в энергетической, металлургической , строительной и других отрасл х промышленности.The invention relates to a pump structure, in particular, to the design of air-lift installations for transporting ash and slag materials to power plants, and can be used in the power, metallurgical, construction and other industries.

Известна эрлифтна установка, содержаща напорный трубопровод, соединенный в нижней части со смесите- . лем, к которому присоединены всасывающий патрубок и воздухопровод С1 .The well-known air-lift installation, containing a pressure pipe connected at the bottom with a mix-. Lem to which the suction nozzle and the air duct C1 are attached.

Недостатком этой установки вл етс низка эффективность при транспортировании крупнокускового материала .The disadvantage of this setup is the low efficiency in transporting the lumpy material.

Наиболее близкой по технической сущности к изобретению вл етс эрлифтна установка, содержаща горизонтальный напорный трубопровод, на одном конце которого закреплен воздухоотделитель , а на другом - смесительThe closest to the technical essence of the invention is an air-lift unit containing a horizontal pressure pipeline, at one end of which an air separator is fixed and at the other end a mixer.

С воздухоподводом и всасывающий патрубок с подпитывающей трубой 2.With air supply and suction nozzle with feed pipe 2.

Недостатком установки вл етс низка эффектиность при Т эанспортировании крупнокускового материала.The disadvantage of the installation is low effect when T is the export of lumpy material.

Цель изобретени - повышение эффективности при транспортировании крупнокускового материала.The purpose of the invention is to increase efficiency in the transportation of lumpy material.

Поставленна цель достигаетс тем, что- всасывающий патрубок снабжен The goal is achieved by the fact that the suction nozzle is equipped with

10 воронкой с вертикальной осью, а лод питывающа труба - насадками.10 is a vertical-axis funnel, and the lod is fed by a nozzle.

На чертеже показана схема установки продольный разрез.The drawing shows the installation diagram of a longitudinal section.

Эрлифтна установка содержит го15 ризонтальный напорный трубопровод 1, на одном конце которого закреплен воздухоотделитель (не показан), а на другом - смеситель 2 с воздухо .подводом 3 и всасывающий патрубок 4 An air-lift unit contains a horizontal pressure pipe 1, at one end of which an air separator (not shown) is fixed, and on the other - a mixer 2 with air. Inlet 3 and suction nozzle 4

Claims

20 with a feed pipe 5, the suction nozzle is provided with a funnel 6 with a vertical axis, and the feed pipe 5 with nozzles 7. 3 The installation works as follows. When air is supplied through the air inlet 3 to the mixer 2 and the pressure pipe 1, the slurry moves in it. In this case, the slurry from the funnel 6 enters the suction inlet pipe k and then into the discharge pipe wire 1. When fluid is supplied through the feed pipe 5 and the nozzle 7, it is intensely affected by the slurry and solid material. The nozzles 7 are directed toward the suction nozzle 4, Therefore, under the action of a jet, the solid material enters the suction nozzle k more intensively. Since the jet velocity at the exit of nozzles 7 is much higher than the speed of the slurry in the suction nozzle k (about 10 or more times), the flow of liquid through nozzles 7 leads to an increase in the performance of the airlift installation and an increase in the speed in the suction Due to this, it is possible to increase the diameter of the suction inlet 4 and the dimensions of the pieces of solid material. Thus, the use of the funnel 6 increases the efficiency of transporting the large-piece material by pumping it all over. The use of the invention reduces the likelihood of blocking the suction pipe and eliminates the work associated with the subsequent launch of the airlift installation. Formula of the invention Airlift installation containing a horizontal pressure pipe at one end the air separator is fixed, and on the other there is a mixer with an air supply and a suction nozzle with a make-up pipe, characterized in that, in order to increase the efficiency for transporting lumpy material, the suction nozzle is equipped with a vertical-axis funnel, and the feed tube is equipped with nozzles.
