A pneumatic universal butt joint air supply device

Abstract

The invention discloses a pneumatic universal butt joint air supply device. The pneumatic universal butt joint air supply device comprises two parts: an air supply mechanism and an air reception mechanism. As a spring is designed, blowing connection can be implemented and finished with in a bigger deviation range, so that the centralized positioning precision is reduced greatly when a steel ladletakes the seat, and a crane driver is more easily to operate the device, the accidents caused by damage in collision of equipment is also reduced, and the device is high in reliability; as the springis designed, the air supply mechanism can return to the initial position of the vertical direction automatically after transmission. The butt joint sealing property is guaranteed by means of a uniquespherical curved soft seal in the air reception mechanism. Functions of butt joint of mechanisms to transmit and deliver air and automatic recovery of the mechanisms can be achieved without manual operations by means of the unique structural design of the air supply mechanism, the safety problem of manual butt joint transmission in complicated working conditions is solved, and the labor intensityof staff is alleviated.

Description

technical field [0001] The invention relates to the field of pressure gas supply and control in industrial production such as refining outside the furnace of modern steelmaking, which can automatically and reliably connect the bottom blowing gas supply pipeline between the ladle car and the ladle in the refining outside the furnace, and specifically relates to a pneumatic Type universal butt air supply device. Background technique [0002] At present, with the development of science and technology and the improvement of steel quality requirements in industry and agriculture, modern steelmaking plants generally adopt out-of-furnace refining production processes to adjust and improve the content of trace elements in molten steel and improve the quality of billets. Refining outside the furnace has become an indispensable and important link in the modern steelmaking process. [0003] Out-of-furnace refining is to add alloy raw materials to the molten steel and ventilate to the ...

AI Technical Summary

Problems solved by technology

[0004] At present, in the external refining production process of domestic steel mills, the connection between the gas supply device on the ladle car and the gas connection device on the ladle is mainly achieved by manually connecting the pipes. ; Some enterprises adopt fixed docking plug devices, the plug part is installed on the ladle car, and the socket part is installed on the steel ladle. The docking needs to be realized by the accurate seating and positioning on the ladle car during the hoisting and lowering of the steel ladle. This kind of docking technology exists as follows Problems: 1. The crane driver lowers the ladle to the ladle car through eye observation and judgment in the traffic control room. To make the ladle sit on the fixed position on the ladle car accurately, the operation is difficult and the risk of damaging the docking equipment is great. ; 2. It takes a long time for manual adjustment and alignment, which leads to the delay of the blowing operation time, and the cooling of molten steel increases the production cost; 3. The docking device on the ladle car and the ladle is fixed. Once the ladle falls off, it is easy to cause blowing at the bottom The device is damaged, affecting the refining production outside the furnace
