Abstract

The invention discloses a secondary lifting device for a powder concentrator. The secondary lifting device consists of a booster fan air inlet pipe, a booster fan, a booster fan air outlet pipe, a connecting air pipe and annular air pipes, wherein the booster fan is positioned outside the powder concentrator; the booster fan air inlet pipe and the booster fan air outlet pipe are arranged on the booster fan; the booster fan air inlet pipe is connected to a main fan air outlet pipe 1 of the powder concentrator; the booster fan air outlet pipe passes through a cone shell of the powder concentrator, and extends to the outer side of a coarse powder cone of the powder concentrator; three layers of annular air pipes are arranged horizontally at certain intervals in the coarse powder cone; the booster fan air outlet pipe is connected with the three layers of annular air pipes through the connecting air pipe; and the annular air pipes are provided with nozzles. Due to the adoption of the secondary lifting device for the powder concentrator, the powder concentrating efficiency of the powder concentrator can be increased, and reduction in the efficiency of a pulverizing mill caused by wrong feeding of qualified products into the pulverizing mill for secondary pulverizing is avoided.

Description

technical field [0001] The invention relates to a secondary lifting device of a powder classifier. Background technique [0002] In the existing powder production process, the coarse powder after the powder is sorted by the powder classifier is accumulated in the coarse powder cone and discharged from the coarse powder pipe, and then sent to the pulverizer for grinding again. Due to the limitations of the material dispersion mechanism of the existing powder separator, the powder selection efficiency of the existing powder separator is only 50% to 70%, that is, the discharged coarse powder still contains a large number of qualified products, and these qualified products are mistakenly Sending to the pulverizer for re-grinding will indirectly reduce the efficiency of the pulverizer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a secondary lifting device for the powder separator, which can improve the powder sel...
