(Ц) ЭРЛИФТ(C) ERLIFT

1one

Изобретение относитс к устройст вам дл добычи песчано-гравийной . галечной массы со дна водоема и .может быть применимо в горной промышле .нности.The invention relates to devices for sand and gravel mining. pebble mass from the bottom of the reservoir and may be applicable in the mining industry.

Известен эрлифт, содержащий камеру смешени , в стенках которой выполнены окна, которые перекрывает эластична перегородка с окнами несовпадающими с окнами в стенках камеры D1.The airlift is known, which contains a mixing chamber, in the walls of which windows are made, which are covered by an elastic partition with windows that do not coincide with the windows in the walls of chamber D1.

Недостатком такого эрлифта вл етс их недолговечность вследствие воздействи на них крупных абразивных частиц. ,The disadvantage of such an airlift is their fragility due to the impact of large abrasive particles on them. ,

Известен также эрлифт, включающий пульпопровод, концентрично расположенную воздушную камеру, подключенную к источнику сжатого воздуха, и запорный элемент 2.Also known airlift, including slurry pipeline, concentric located air chamber connected to a source of compressed air, and the locking element 2.

Недостатком этого эрлифта вл етс недостаточна эффективность работы.The disadvantage of this airlift is the lack of operational efficiency.

Цель изобретени - повышение эффективности работы.The purpose of the invention is to increase work efficiency.

Поставленна цель достигаетс тем, что в эрлифте, включающем пульпровод, камеру, установленную концентрично относительно пульпопровода и по/ ключенную к источнику сжатого воздуха, и запорный элемент с щелевыми отвер сти ми, установленный з камере, последн выполнена с пазом, а запорный элемент снабжен фиксатором, установленным с возможностью расположеto ни в пазу камеры, при этом участок пульпопровода расположен в камере и имеет щелевые отверсти .This goal is achieved by the fact that in an airlift that includes a pulpowel, a camera installed concentrically with respect to the pipeline and connected to a source of compressed air, and a locking element with slotted holes installed from the camera, the latter is made with a groove installed with the possibility of being located in the groove of the chamber, while the section of the pipeline is located in the chamber and has slit holes.

Claims

FIG. 1 shows the proposed device, a general view; in fig. 2, section A-A in FIG. 1 ″, in FIG. 3, a device with a horizontal arrangement of slotted holes; Fig, the same, with a vertical arrangement. 20 Airlift (Fig. 1) consists of a slurry pipeline 1 having slotted apertures 1. For air intake, an external air chamber 3, closed with a removable cover, having apertures 5 for communicating the lower part of the air chamber with a body of water. The top cover 6 of the air chamber has an opening 7 for supplying air. Inside the air chamber there is a shut-off element 8 made of stainless material, having a closed air, cavity 9 and air channels 10 communicating with the air chamber. The outer surface of the locking element fits precisely to the side wall 11 of the air chamber. In: the wall of the locking element is screwed retainer 12, which fits into the groove of the air chamber. The groove is covered by a lid 1 i. The slit holes can be positioned obliquely (Fig. 1), horizontally in Several Rus (Fig. 3) or vertically (Fig.), In the first case the slope of the slit holes and the screw groove should be directed in different directions. With the horizontal arrangement of the air channels (Fig. 3), their connection with each other and with the air chamber is carried out by the longitudinal channels 1b. When air is supplied, the locking element 8 is pressed to the lower position. Due to the sliding of the clamp 12 in the groove 13, the locking element 8 is rotated and its longitudinal channels 10 are aligned with the slit holes 2 of the slurry line, and air from the air chamber 3 enters the slurry line 1, which is the formation of a water-air mixture. When the locking element is moved downward, the water under the water is squeezed out through the opening 5. When the air supply is stopped, the locking element floats up, at 93 ° C 5TOM the latch 12 slides into the groove 13, which causes the slurry pipe 2 to pivot and overlap, thereby preventing water from entering into the air chamber and clogging it with solid particles moving in the pulp flow. The invention ensures uninterrupted operation of the airlift, since the design of the air-distributing device eliminates the clogging of air supply channels with solid particles. The rotatable closure element provides for the overlapping of the slit holes when the air pressure drops, which prevents solid particles from entering the air chamber. The invention of Airlift, which includes a slurry pipeline, a chamber mounted concentrically with respect to the slurry pipeline and connected to a source of compressed air, and a locking element with slotted openings installed in the chamber, are distinguished by the fact that the chamber is slotted , and the locking element is provided with a clamp installed with the possibility of being located in the groove of the chamber, while the section of the slurry pipeline is located in the chamber and has slotted holes.
