Изобретение относитс к насосостро .ению.в частности к конструкци м эрлифта , и может быть использовано при проектировании гидротранспортных систем в промышленности и сельском хоз йстве .The invention relates to pump engineering. In particular, to airlift structures, and can be used in the design of hydrotransport systems in industry and agriculture.

Известен эрлифт, содержащий подъемную трубу со смесителем и обогатителем и воздухоподвод l.Known airlift, containing a lifting pipe with a mixer and a concentrator and air supply l.

Недостатком этого эрлифта вл ет- ,д с низкий КПД.The disadvantage of this airlift is em-, dc low efficiency.

Наиболее близким к изобретению по технической сущности вл етс эрлифт, содержащий водоподъемную трубу, воздухопровод и размещенный по оси трубы ,s русный обогатитель с входными щел ми 2.Closest to the invention, in technical terms, is an airlift containing a water lift pipe, an air duct and located along the pipe axis, a fresh enrichment vessel with entrance slits 2.

Недостатками известного эрлифта вл ютс низкий КПД и узкий диапазон работы.The disadvantages of the known airlift are low efficiency and narrow range of operation.

Цель изобретени - повышение КПД и расширение диапазона работы.The purpose of the invention is to increase efficiency and expand the range of operation.

Поставленна цель достигаетс тем, что каждый рус обогатител выполнен в виде патрубка с расшир ющимс нижним участком, снабженным с внутренней стороны направл ющими реб-. рами, равномерно размещенными по окружности и центрирующими соседний патрубок, причем патрубки установлены с возможностью относительного вертикального перемещени , а ребра имеют в верхней части отгибы, ориентированные в окружном направлении.The goal is achieved by the fact that each enrichment enamel is made in the form of a branch pipe with an expanding lower section, which on its inner side is equipped with rebates. frames evenly placed around the circumference and centering the adjacent nozzle, the nozzles being installed with the possibility of relative vertical movement, and the ribs have in the upper part of the bends oriented in the circumferential direction.

На фиг. 1 схематически показан предлагаемый эрлифт, продольный разрез; на фиг. 2 - узел стыковки соседних патрубков.FIG. 1 schematically shows the proposed airlift, longitudinal section; in fig. 2 - docking unit adjacent pipes.

Claims

The airlift contains a water lifting pipe 1, an air duct 2 and a 1 brown concentrator 3 located along the pipe axis with entrance holes k, each of which is a Russian enrichment agent. 3 is made in the form of a pipe 5 with an expanding lower section 6, provided on the inside with guide ribs 1 evenly spaced around the circumference and centering the adjacent pipe, while the pipes 5 are installed with the possibility of relative vertical movement, and the edges 7 are in the upper part of the limb 8, oriented in the circumferential direction. The airlift operates as follows. The air entering through the air duct 2 into the lower part of the enrichment unit 3 rushes upward, trapping along. the path of the water particles and the image of the water-air emulsion (mixture) that is carried along the lifting pipe 1 to the outside. Created at the same time, ha ha ensures a constant suction of water from the well into the concentrator 3 through its lower end and laterally through the annular inlet slits t. Thanks to the guide ribs 7, evenly placed around the circumference, a uniform (around the perimeter of the concentrator 3) flow into the annular gaps of the sucked water is achieved and its parallel-streaming movement is organized, which ensures its further flow in the concentrator 3 without transverse twisting, which the turn prevents stratification of the water-air emulsion. The execution of the ribs 7 with the folds 8 causes an increase in the turbulization of the near-wall layer of the emulsion flow due to the interaction of the jets of adjacent Rus, which contributes to a more intensive involvement of air bubbles into the near-wall layer and thereby increase the efficiency of the device. The movable connection of adjacent piping, which provides them with the possibility of a relative vertical movement, allows the height of the concentrator 3 to be changed and the optimum dimensions of the cross-sectional areas of the annular inlet slits A, thereby reducing their hydraulic resistance. The proposed improvements significantly increase the efficiency of the airlift and expand its range of operation. Claim 1, Airlift, containing a water-lifting pipe, an air duct and a brown concentrator with entrance slits located along the pipe axis, characterized in that, in order to increase efficiency and expand the range of operation, each enrichment rus is made in the form of a branch pipe with an expanding lower section, fitted on the inside with guide ribs evenly spaced around the circumference and centering the adjacent nozzle. 2. The airlift according to claim 1, which is also distinguished by the fact that the nozzles are installed with the possibility of relative vertical movement, and the ribs have in the upper part bends oriented in the circumferential direction.
