Description

Technical Field

[0001] The utility model relates to the technical field of sand mills, and more specifically to a multi-stage grinding horizontal ink sand mill. Background Art

[0002] Horizontal ink sand mill is a horizontal sand mill. It is a high-efficiency wet ultrafine grinding and dispersing machine widely used in non-metallic mining industries such as coatings, dyes, paints, inks, medicines, magnetic powders, ferrites, photosensitive films, pesticides, papermaking and cosmetics. Common horizontal ink sand mills usually have one set of grinding cylinders, while multi-stage grinding horizontal ink sand mills have multiple sets of grinding cylinders, and then multiple sets of grinding cylinders are used to achieve multi-stage grinding effects.

[0003] The multi-stage grinding method of the existing multi-stage grinding horizontal ink sand mill is mainly to grind the ink in the upper grinding cylinder for a certain period of time, and then open the channel connected to the lower grinding cylinder to transport the ink in the upper grinding cylinder to the lower grinding cylinder for further grinding. However, in this process, the ink that has not been thoroughly ground in the upper grinding cylinder will enter the lower grinding cylinder for grinding, which will greatly affect the multi-stage grinding effect and reduce the performance of the device. In view of this, we propose a multi-stage grinding horizontal ink sand mill. Utility Model Content

The ink first enters the upper grinding cylinder 2 for initial grinding, and the initially ground ink will enter the box body 5 below it. The filtering structure 6 inside the box body 5 filters and separates the initially ground ink. The qualified ink will pass through the filtering structure 6 and then enter the lower grinding cylinder 3 for secondary grinding. The unqualified ink will be retained above the filtering structure 6, and then the conveying pump 8 on the upper grinding cylinder 2 will convey the unqualified ink inside the box body 5 to the upper grinding cylinder 2 again for continued grinding, until the ink in the upper grinding cylinder 2 completely meets the standards and enters the lower grinding cylinder 3. The ink after the initial grinding enters the lower grinding cylinder 3 for secondary grinding. This process is the same as above until the ink in the lower grinding cylinder 3 completely meets the standards and is discharged.

[0024] Specifically, a first connecting tube 501 is arranged in the center of the top of the box body 5, and a second connecting tube 502 is arranged in the center of the bottom of the box body 5. The first connecting tube 501 on the separation and conveying structure 4 at the bottom of the upper grinding cylinder 2 is connected to the output end of the bottom of the upper grinding cylinder 2, the second connecting tube 502 on the separation and conveying structure 4 at the bottom of the upper grinding cylinder 2 is connected to the input end at the top of the lower grinding cylinder 3, and the first connecting tube 501 on the separation and conveying structure 4 at the bottom of the lower grinding cylinder 3 is connected to the output end at the bottom of the lower grinding cylinder 3.

The partition plate 601 is arranged in the box body 5, and the filter mesh plate 602 is arranged in the center of the partition plate 601. A guide structure 7 symmetrical to the filter mesh plate 602 is arranged on the top of the box body 5.

[0029] Working principle: This embodiment provides a multi-stage grinding horizontal ink sand mill. When in use, first, the ink enters the upper grinding cylinder 2 for initial grinding, and the initially ground ink will enter the box body 5 below it. The filtering structure 6 inside the box body 5 filters and separates the initially ground ink. The qualified ink will pass through the filtering structure 6 and then enter the lower grinding cylinder 3 for secondary grinding. The unqualified ink will be retained above the filtering structure 6, and then the delivery pump 8 on the upper grinding cylinder 2 will deliver the unqualified ink inside the box body 5 to the upper grinding cylinder 2 again for continued grinding, until the ink in the upper grinding cylinder 2 completely meets the standards and enters the lower grinding cylinder 3. The ink after the initial grinding enters the lower grinding cylinder 3 for secondary grinding. This process is the same as above, until the ink in the lower grinding cylinder 3 completely meets the standards and is discharged;

[0030] Secondly, the ink enters the main pipe 701 through the first connecting pipe 501, and then the ink enters the diversion pipe 702 respectively, and finally the ink is discharged from the various diversion ports 703 of the diversion pipe 702 and falls onto the filter mesh plate 602, that is, the ink falls on the filter mesh plate 602 over a large area, thereby improving the efficiency of filtration and separation. When the ink passes through the filter mesh plate 602, qualified ink directly passes through the filter mesh plate 602, and unqualified ink will quickly slide around and separate from the filter mesh plate 602 under the inclined guidance of the top surface of the filter structure 6. Therefore, it can effectively prevent unqualified ink from remaining on the filter mesh plate 602 and affecting the subsequent filtration and separation of the ink, thereby ensuring the filtration and separation effect of the filter structure 6 on the ink.
