Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mineral processing equipment and relates to a desludging column. Background Art
[0002] Due to its large specific surface area, ore slime often absorbs a large amount of reagents during the mineral processing process, resulting in large amounts of reagents and low concentrate grade. Therefore, when processing oxidized ores with high mud content, desludging is often performed. Existing desludging equipment mainly includes: desludging screens, desludging buckets, cyclones, etc., but the desludging speed is slow, the desludging accuracy is low, and the area occupied is large. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a desludging column, comprising an ore feeding box, an ore feeding pipe, a discharge valve, a constant pressure water feeding box, a water feeding pipe, a desludging column and an overflow port, wherein the upper part of the desludging column is provided with an ore feeding pipe, the lower part of the desludging column is provided with a water feeding pipe, the top of the desludging column is provided with an overflow port, and the bottom of the desludging column is provided with a discharge valve; the ore feeding box is connected to the ore feeding pipe, and the constant pressure water feeding box is connected to the water feeding pipe.
[0004] The overflow port is connected to an overflow particle size analyzer through a pipeline.
[0005] The discharge valve is connected to the bottom flow particle size analyzer through a pipeline.
[0006] Compared with the prior art, the utility model has the following advantages: the utility model has the advantages of small footprint, convenient layout, large processing capacity, low energy consumption, good separation effect, etc. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
[0008] Figure 1 It is a schematic diagram of the structure of the utility model.
[0009] In the figure: 1 - feed box 2 - feed pipe 3 - discharge valve 4 - constant pressure water tank 5 - water pipe 6 - desludging column 7 - overflow port 8 - overflow particle size analyzer 9 - underflow particle size analyzer. DETAILED DESCRIPTION
[0010] like Figure 1A desludging column includes a feed box 1, a feed pipe 2, a discharge valve 3, a constant-pressure water tank 4, a water pipe 5, a desludging column 6, and an overflow port 7. The feed pipe 2 is located above the desludging column 6, the water pipe 5 is located below the desludging column 6, the overflow port 7 is located at the top of the desludging column 6, and the discharge valve 3 is located at the bottom of the desludging column 6. The feed box 1 is connected to the feed pipe 2, and the constant-pressure water tank 4 is connected to the water pipe 5. The overflow port 7 is connected to an overflow particle size analyzer 8 via a pipeline, and fine particles are discharged through the overflow port 7. The discharge valve 3 is connected to an underflow particle size analyzer 9 via a pipeline, and coarse particles are discharged through the discharge valve 3, and the output can be controlled.
[0011] When the equipment is working, the material that needs to be desludged flows into the feeding pipe 2 through the feeding box 1. The feeding pipe 2 evenly distributes the material in the column 6, and its movement direction is from top to bottom. The required water source enters the water feeding pipe 5 through the constant pressure water feeding tank 4, thereby generating a uniform rising water flow, and its movement direction is from bottom to top. The material is separated into coarse and fine particles under the combined action of gravity and the impact force of the rising water flow. Fine particles are discharged through the overflow port 7, and coarse particles are discharged through the discharge valve 3. The fineness of the overflow and bottom flow particles is respectively detected by the overflow particle size analyzer 8 and the bottom flow particle size analyzer 9 installed on the pipeline. When the overflow fineness is finer than the predetermined fineness, the pressure of the constant pressure water feeding tank 4 is increased through the control system, so that the coarser particles enter the overflow. Otherwise, the pressure of the constant pressure water feeding tank 4 is reduced, so that the coarser particles enter the bottom flow.
[0012] The above is a preferred embodiment of the present invention. Technicians in the field of the present invention can also change and modify the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvements, replacements or modifications made by technicians in this field on the basis of the present invention are within the scope of protection of the present invention.
