Detailed Description
The embodiment of the utility model is applied to the comprehensive utilization operation department of Baoshan mining company of Baoshan Steel (group) company, selects No. 7 sand pump station NXZ-45 rake thickener underflow and reforms transform, and the original design adopts thickener underflow homonymy to ore deposit. In production operation, the stress of the thickener rake is gradually increased along with the increase of the underflow concentration of the thickener. The ore discharging mode of the traditional thickener is adopted in the ore discharging mode of figures 3 and 4. 1. 2, the same underflow pipe is arranged at the ore discharge port, and the underflow pump is used for pumping to a corresponding process position. No. 1 ore discharge port and No. 2 ore discharge port are arranged on the same pipeline, and No. 2 ore discharge port is arranged at the front end of the underflow pipeline, so that ore discharge is smooth; the ore discharge is slow at the No. 1 ore discharge port, and the minerals are easy to accumulate; in addition, the traditional ore discharging mode adopts No. 1 and No. 2 ore discharging openings to discharge ores, and the angle is about 104 degrees. When the thickener operates, the ore amount from the No. 2 ore discharge port to the No. 1 ore discharge port with an angle of about 260 degrees rotates clockwise to the No. 1 cone port for ore discharge along with the auxiliary rake of the thickener, and minerals are easier to accumulate at the cone port, as shown in figure 4. Often times, plugging of the draw hole occurs at thickener underflow concentrations in excess of 60%. Due to uneven ore discharge of the thickener, the pressure of the thickener is easily over-high, and the production operation stability is affected by frequent rake lifting.
In the modification of the example, the first step is to change the original ore discharging mode at a small-angle ore discharging opening (104 degrees) into a large-angle ore discharging opening (180 degrees), as shown in fig. 5. Along with the clockwise rotation of the thickener rake, the ore loading amount on the conical surface of the thickener uniformly passes through the ore loading port; the utility model adopts the No. 1 ore discharge port 1 and the No. 3 ore discharge port 3 to discharge ore, which can ensure the uniform ore discharge of the thickener and solve the problems of over-high pressure and rake lifting of the uneven ore discharge of the No. 1 and No. 2 ore discharge ports of the thickener;
secondly, the two underflow pipes 5 are additionally provided with communicated ore storage boxes 6, ore discharging ports respectively and independently discharge ore and then enter the ore storage boxes 6, and after temporary storage and uniform mixing, the concentration of ore pulp conveyed by an underflow pump is more stable; the added ore storage box 6 can realize the free switching of ore discharge of the No. 1 ore discharge port 1, the No. 3 ore discharge port 3 ore discharge and the No. 2 ore discharge port 2, the No. 4 ore discharge port 4 ore discharge without reversing the pump; meanwhile, the inverted pump of the underflow pump does not influence the running modes of ore discharge of the ore discharge openings 1 and 3 and the running modes of ore discharge openings 2 and 4 of the two ore discharge openings 1 and 3, the two ore discharge openings are mutually standby, and the production operation is more stable and reasonable.
The utility model solves the problems that the on-site thickener is not uniform in ore discharge and the pressure of the thickener rake is too high to meet the concentration of the process requirement before the reformation is implemented, and by using the utility model, the underflow concentration of the on-site thickener meets the process requirement, the ore discharge of the thickener is uniform and stable, and the stable and smooth production is realized;
the method is applied to a Baiyunebo oxidized ore-resource comprehensive utilization mixed flotation 60-meter thickener, a 60-meter water treatment thickener and a fluorite flotation 50-meter thickener; the reconstruction cost is 7.65 ten thousand (4.5 ten thousand yuan plus 3.15 ten thousand yuan for the pipeline); after the improvement, the ore discharging of the thickener is stable, the emptying inspection, the overhaul and the like caused by overhigh pressure of the thickener rake are avoided, and the direct economic benefit is 37.8 ten thousand per year.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
