U-shaped inclined tube for inclined tube thickener and splicing method of U-shaped inclined tube

Abstract

The invention relates to a U-shaped inclined tube for an inclined tube thickener and a splicing method of the U-shaped inclined tube, belongs to the technical field of underground coal preparation, and solves the problems that the precipitation efficiency is low and the combination mode is complicated due to sheet overlapping during installation of the existing inclined tube. The U-shaped inclined tube comprises a plurality of layers of waveform sheets and a plurality of parallel sheets. Each layer of waveform sheet comprises a plurality of U-shaped sheets, and a first plug and a third plug are arranged at the two ends of each U-shaped sheet respectively. One end of each parallel sheet is provided with a first groove and a second groove, and the first plugs and the third plugs of the adjacent U-shaped sheets are respectively clamped to and connected with the first groove and the second groove of the same parallel piece to form a waveform sheet. A second plug is arranged at the bottom of each U-shaped sheet. A third groove is formed in the other end of each parallel sheet. The second plugs are connected with the third grooves in a clamped mode, and connection between the multiple layers of waveform sheets is achieved. Rapid splicing of the U-shaped inclined tube is achieved through mutual clamping of the waveform sheets and the parallel sheets.

Description

technical field [0001] The invention relates to the technical field of underground coal preparation, in particular to a U-shaped inclined pipe used in an inclined pipe thickener and a splicing method thereof. Background technique [0002] The inclined tube thickener is one of the most core equipment in the coal preparation process. It is widely used in coal preparation plants because of its high sedimentation efficiency and small footprint. There is almost no change in the type and process performance, and the honeycomb hexagonal inclined tube is basically used, but this inclined tube still has certain defects. [0003] The existing inclined tubes are simple to manufacture, but overlapping sheets will occur during installation, occupying the sedimentation area and restricting the sedimentation efficiency. At the same time, the existing inclined tubes are installed by ironing to form a huge and complete inclined tube block, the operation is very complicated. [0004] The in...
