Problems solved by technology

This method fails to make full use of the advantages of dry stockpiling. When it rains, the water accumulation area is large, and the storage yard can maintain the dry beach length that meets the requirements of the regulations. The use time is short, and the vertical shaft window is completely useless after being blocked

Embodiment Construction

[0019] Embodiment 1 of the present invention: a flood discharge shaft 1 with a reinforced concrete structure is arranged in the middle of the storage yard, and the bottom of the flood discharge shaft 1 is connected with a flood discharge pipeline 2, and several rows of windows 3 are set at regular intervals along the height direction on the well wall of the flood discharge shaft 1, The window 3 is a hole with a large outside and a small inside, and its cross-sectional shape is circular, oval, square, and other shapes. Window 3 is also equipped with a blocking plate 5 with the same cross-sectional shape. The size of blocking plate 5 is between the inside and outside dimensions of window 3. Its skeleton is welded with steel bars, and it is covered with a layer of geotextile inside and outside.

[0020] The storage yard can be put into operation after the embankment is repaired. After the red mud filter cake is transported to the storage yard, it is firstly placed near the embankm...

Abstract

The invention discloses a flood discharge structure for a red mud filter cake storage yard. The flood discharge structure comprises a flood discharge vertical shaft (1) arranged in the middle of the storage yard, wherein the wall of the flood discharge vertical shaft (1) is provided with a plurality of rows of windows (3); and the bottom of the flood discharge vertical shaft (1) is connected with a flood discharge pipeline (2). The flood discharge structure is characterized by also comprising a flood discharge vertical shaft (1)-centered flood regulation tank (4), wherein the whole flood regulation area is in a column basin shape; and each window (3) is provided with a blocking plate (5). A diluvial area of the storage yard is limited in a small range, so that the decrease speed of dry beach length of the storage yard is reduced, the safe operation time of the storage yard is prolonged, and the effective storage of the storage yard is increased; meanwhile, a novel structure of the windows and the blocking plates thereof is adopted, so that the solidification of red mud nearby the vertical shaft is accelerated, and the safety stability of the storage yard is facilitated.

Description

technical field [0001] The invention relates to a flood discharge structure for a red mud filter cake storage yard, and belongs to the technical field of red mud storage in alumina production. Background technique [0002] Red mud is the waste residue produced in alumina production. Except for a small amount that can be comprehensively utilized, each alumina plant needs to build a special red mud storage yard to stack red mud. [0003] The current mainstream technology for red mud storage is wet storage. However, some domestic enterprises currently use the dry method of filtering the red mud and sending it to the storage yard by car. [0004] The flood discharge method of the wet red mud storage yard is generally to set up a window-type flood drainage shaft in the middle of the storage yard, and several rows of windows are arranged on the shaft. After the red mud slurry is sent to the storage yard by pipeline, it is discharged on the embankment. The solid particles (red mu...
