Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment, in particular to a ball material separation device for discharging material from a laboratory sand mill. Background Art

[0002] Ore dressing is an important technology for efficient utilization of mineral resources, and ultrafine grinding of materials is often involved in the process of ore dressing experiments. In recent years, Ai sand mill, as a new type of ultrafine mill, has been widely used in experiments and production practices. However, in the process of continuous grinding and discharging using Ai sand mill in the laboratory, some of the worn grinding media are mixed into the grinding slurry and discharged together, which not only affects the quality of the test, but also some of the grinding media brought out reduces the filling rate of the Ai sand mill, thereby affecting the grinding effect. In summary, there is a need for a device with a simple structure, strong practicality, and the ability to effectively complete the separation of balls and materials in the discharging process of the laboratory Ai sand mill. Utility Model Content

[0003] The utility model aims to provide a device which has a simple structure, strong practicability and can effectively complete the ball-material separation in the unloading process of a laboratory sand mill.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A ball material separation device for unloading a laboratory sand mill comprises a separation tube, which is a three-way structure, with an inlet and an outlet at both ends of the separation tube respectively, a mounting opening in the middle of the separation tube, a ball filter arranged at the mounting opening, the top of the ball filter matching the inside of the separation tube, a half opening arranged on the side of the top of the ball filter facing the inlet, an opening arranged at the bottom of the ball filter, and overflow holes evenly arranged on the side wall of the ball filter at positions corresponding to the half openings.

[0006] A further technical solution is that a first mounting flange is arranged at the mounting port, the first mounting flange is connected to a sealing flange, a through hole is arranged in the middle of the sealing flange, a ball unloading tube is fixedly connected to the through hole, and a ball unloading valve is arranged on the ball unloading tube.

[0007] A further technical solution is that the inlet is connected to a discharge pipe of the sand mill, and a cut-off valve is provided on the discharge pipe.

[0008] A further technical solution is that the discharge pipe is connected to a flushing pipe, and a flushing valve is provided on the flushing pipe.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0010] The utility model provides a separation pipe and a ball filter. When the sand mill is unloading, the ball discharge valve and the flushing valve are closed and the cut-off valve is opened. The slurry in the sand mill enters the discharge pipe and the separation pipe in sequence, and enters the ball filter through the upper half opening of the ball filter for ball-material separation. The grinding medium mixed with the slurry is retained in the ball filter, and the slurry is discharged from the outlet through the overflow hole provided in the ball filter, which effectively prevents the grinding medium from being discharged with the slurry.

[0011] After unloading, close the shut-off valve, open the flushing valve of the flushing pipe, and flush to ensure that the slurry is completely discharged. After cleaning, open the ball unloading valve of the ball unloading pipe, unload the grinding medium into the container, and add it back to the Ai sand mill through the ball adding pipe, which effectively ensures the filling rate of the grinding medium of the Ai sand mill and the grinding quality. In addition, the ball material separation device is made of stainless steel, which effectively prevents corrosion caused by water during the unloading process and prolongs its service life.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 6 shown.

[0020] A ball material separation device for unloading a laboratory sand mill comprises a separation tube 3, wherein the separation tube 3 is a three-way structure, the two ends of the separation tube 3 are respectively an inlet 24 and an outlet 25, the middle of the separation tube 3 is an installation opening 26, a ball filter 5 is arranged at the installation opening 26, the top of the ball filter 5 matches the inside of the separation tube 3, and a half opening 23 is arranged on the side of the top of the ball filter 5 facing the inlet 24, an opening is arranged at the bottom of the ball filter 5, and overflow holes 16 are evenly arranged on the side wall of the ball filter 5 at the position corresponding to the half opening.

[0021] When in use, the separation pipe 3 is connected to the discharge pipe 1 of the sand mill 19, whereby the separation pipe 3 is divided into two parts, namely, the 1# discharge pipe 131 and the 2# discharge pipe 141, the 1# discharge pipe 131 is connected to the inlet 24 of the separation pipe 3, the 2# discharge pipe 141 is connected to the outlet 25 of the separation pipe 3, the inlet 24 and the outlet 25 of the separation pipe 3 are welded with a second mounting flange 22, the right end of the 1# discharge pipe 131 is welded to the discharge end of the sand mill 19, the left end is welded with a connecting flange 2, the connecting flange 2 is bolted to the second mounting flange 22 at the inlet 24 of the separation pipe 3, and a sealing ring 7 is arranged between the connecting flange 2 and the second mounting flange 22, the right end of the 2# discharge pipe 141 is welded with a connecting flange 2, the connecting flange 2 is bolted to the second mounting flange 22 at the outlet 25 of the separation pipe 3, and a sealing ring 7 is arranged between the second mounting flange 22 and the connecting flange 2. The size of the ball filter 5 matches the separation pipe 3. Overflow hole 16 size ≤ 3 / 4 of the grinding medium size of the sand mill 19.

[0022] When the ball material separation device of the utility model is used to unload the laboratory Ai sand mill 19, the slurry in the Ai sand mill 19 enters the 1# discharge pipe 13 and the separation pipe 3 in turn, and enters the ball filter 5 through the upper half opening of the ball filter 5 for ball material separation, and the grinding medium mixed with the slurry is retained in the ball filter 5. The slurry passes through the overflow hole 16 provided in the ball filter 55 and enters the 2# discharge pipe 14 for discharge, which effectively prevents the grinding medium from being discharged with the slurry.
