Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of ore dressing, especially relates to a ore discharging device for laboratory Isa mill. BACKGROUND
[0002] The ore grinding is an important part of the ore dressing experimental research, the new Isa mill ore grinding equipment in the laboratory, when the ore grinding, the stirring disc in the cylinder is rotated at high speed under the driving of the main shaft, so that the ore grinding medium makes the axial motion and the rotation motion, the mineral particles are subjected to the scouring force of the high-speed moving ore grinding medium, and the fine grinding is realized. When the Isa mill continuously grinds the ore, the ore grinding medium rotates at high speed, and the ore pulp is smoothly discharged. However, during the laboratory test, the batch ore grinding is often implemented. During the batch ore grinding, the rotation speed of the main shaft is usually reduced, and the clean water is input to empty the ore pulp that has been ground in the cylinder. At this time, due to the reduced rotation speed, the ore grinding medium (ceramic ball with a diameter of 1-6 mm) is usually discharged together with the ore pulp. Then, the ore grinding medium is manually selected from the ore pulp and added into the cylinder for reuse. This mode causes a large labor intensity and a long time consumption, and seriously affects the test progress. CONTENT
[0003] The utility model aims at solving the problems that the ore grinding medium (ceramic ball) is discharged together with the ore pulp in the batch ore grinding process of the prior art, the ore grinding medium in the cylinder is reduced, the labor intensity is large, the time is long, and the test progress is seriously affected, and provides an ore discharging device for laboratory Isa mill.
[0004] The utility model adopts the technical scheme as follows:
[0005] An ore discharging device for laboratory Isa mill, which comprises a main pipe, a side pipe, a bottom plate, a valve, a joint and a high-pressure water device. One end of the main pipe is welded with the bottom plate, and the other end is welded with the joint. The side pipe is welded in communication with the bottom plate end of the main pipe at an acute angle. The other end of the side pipe is connected with the high-pressure water device. The valve is installed on the side pipe. The bottom plate is uniformly provided with ore pulp small holes. The diameter of the ore pulp small holes is smaller than that of the ore grinding medium.
[0006] Preferably, the joint is connected with the ore discharging pipe of the Isa mill through a clamp.
[0007] As the above technical scheme is adopted, the utility model has the beneficial effects as follows:
[0008] With the discharge of the ore pulp, part of the ore grinding medium (the ore grinding medium that needs to be manually selected after the original discharge) will enter the ore discharging pipe. The high-pressure water flow of the utility model can flush the part of the ore grinding medium back into the Isa mill cylinder, so that the manual selection is not needed, the batch ore grinding efficiency of the Isa mill is greatly improved, the time is saved, and the labor intensity is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 2 is the bottom plate structure schematic diagram of the utility model.
[0011] In the drawing: 1-main pipe, 2-side pipe, 3-bottom plate, 31-mineral pulp small hole, 4-valve, 5-joint, 6-high pressure water device, 7-Aisa mill cylinder, 8-milling medium, 9-Aisa mill ore discharge pipe, 10-cylinder clean water valve, 11-cylinder overflow port. DETAILED DESCRIPTION
[0012] In order to make the utility model purposes, technical scheme and advantages more clearly, the following is combined with the drawings and examples, and the utility model is further explained in detail.
[0013] As Figs. 1-2 shown, a kind of ore discharge device for laboratory Aisa mill, including main pipe 1, side pipe 2, bottom plate 3, valve 4, joint 5 and high pressure water device 6, main pipe 1 one end welding bottom plate 3, the other end welding joint 5, and joint 5 is connected with Aisa mill ore discharge pipe 9 by clamp, side pipe 2 is close to bottom plate 3 end of main pipe 1 and is welded to communicate with the end in acute angle, side pipe 2 other end connects high pressure water device 6, valve 4 is installed on side pipe 2, bottom plate 3 is evenly distributed with mineral pulp small hole 31, and the diameter of mineral pulp small hole 31 is less than the diameter of milling medium 8.
[0014] Working process and principle: when Aisa mill batch test ore discharge, first set up main shaft low speed operation, open cylinder clean water valve 10 from Aisa mill cylinder 7 end and input clean water, and mineral pulp and small amount of milling medium 8 are by Aisa mill cylinder 7 through Aisa mill ore discharge pipe 9 and enter main pipe 1 by joint 5, and mineral pulp is discharged from the mineral pulp small hole 31 of bottom plate 3 and becomes qualified milling product, and milling medium 8 is blocked in main pipe 1 by bottom plate 3;When the mineral pulp small hole 31 of bottom plate 3 discharges clean water, close cylinder clean water valve 10, open cylinder overflow port 11 blind plate in the upper end of Aisa mill cylinder 7, and simultaneously open valve 4, and high pressure water is transported by high pressure water device 6, and milling medium 8 retained in main pipe 1 is washed back into Aisa mill cylinder 7, and when cylinder overflow port 11 discharges clean water, close valve 4, and finally realize the separation of mineral pulp and milling medium 8, and the purpose of milling medium 8 returning to Aisa mill cylinder 7.
