AI Technical Summary

Technical Problem

In the hydrometallurgical process of nickel-cobalt ore, the difficulty in removing the overflow pipe from the reactor is mainly due to the high viscosity of the material, which causes sludge to accumulate and form debris between the overflow pipe and the connecting channel. As the disassembly process progresses, the resistance increases, making disassembly difficult.

Method used

A reactor device was designed in which the conical part of the discharge nozzle gradually narrows away from the overflow pipe and is connected by a flange and threaded fasteners to achieve a detachable connection between the overflow pipe and the discharge nozzle. Combined with a positioning structure and a sealing gasket, the gap between the conical part and the connection channel is increased to loosen the debris and reduce the disassembly resistance.

Benefits of technology

By increasing the gap between the conical part and the connecting channel, the density of debris accumulation is reduced, the ease of disassembly of the discharge nozzle and overflow pipe is improved, maintenance costs are reduced, and assembly accuracy and sealing are enhanced.

Abstract

The utility model belongs to the technical field of metallurgical devices, and particularly provides a reaction kettle device which comprises a reaction kettle, a discharging pipe, an overflow pipe and a discharging nozzle, the reaction kettle is provided with a reaction cavity and a connecting channel, one end of the discharging pipe is located in the reaction cavity, and the other end of the discharging pipe is located in the connecting channel and communicates with the overflow pipe through the discharging nozzle. The discharging nozzle comprises a conical part, the conical part is provided with a connecting hole communicated with the pipe cavity of the overflow pipe, the boundary dimension of the conical part is gradually reduced in the direction away from the overflow pipe, and the conical part is inserted into the connecting channel and arranged on the discharging pipe in a sleeving mode through the connecting hole. The boundary dimension of the conical part is gradually reduced in the direction away from the overflow pipe, so that the gap between the outer wall of the conical part and the inner wall of the connecting channel is gradually increased in the direction away from the overflow pipe, and compared with the gap which is kept unchanged, the gap increase is beneficial to loosening disintegrating slag and reducing the bulk density of the disintegrating slag; therefore, the extraction resistance of the discharge nozzle is reduced, and the convenience of dismounting the discharge nozzle and the overflow pipe is improved.
