Description

Technical Field

[0001] The utility model relates to the technical field of material grinding equipment, in particular to a double-action vortex mill and a nano-modified clay production line using the same. Background Art

[0002] Sand mills are currently the most adaptable, advanced, and efficient grinding equipment. Based on their performance, they can be broadly categorized into horizontal, basket, and vertical sand mills. Sand mills have a narrow grinding chamber, small clearances between the levers, and intensive grinding energy. Combined with high-performance cooling systems and automatic control systems, they enable continuous processing and discharging of materials, greatly improving production efficiency. Large horizontal sand mills, in particular, have become practical for ultrafine grinding of mineral powders, thanks to the recent advancements in their design and manufacturing technology.

[0003] Previously, the inventors of this utility model have developed the following mill technologies: ① a vertical nano-sand mill, a sand milling system, and a sand milling method thereof, as disclosed in Chinese patent publication No. CN116078495A; ② a sand milling system with circulating grinding media, as disclosed in Chinese patent publication No. CN114011529A; ③ a chambered continuous grinding and dispersing vibration ball mill, a grinding system, and a grinding method, as disclosed in Chinese patent publication No. CN114632593A; ④ a target-type circulating multi-stage air flow mill device, as disclosed in Chinese patent publication No. CN217796546U; ⑤ a vertical nano-sand mill and a sand milling system, as disclosed in Chinese patent publication No. CN219334409U; and ⑥ an ultrasonic vortex mill and a nanoclay preparation system having the mill, as disclosed in Chinese patent publication No. CN209034524U. All of these are grinding technologies created by the inventors of this application.

[0004] Building on the aforementioned grinding technology, the inventors discovered that existing equipment for implementing collision grinding using internal teeth on a grinding disc utilizes a combination of a moving grinding disc and a stationary grinding disc.

However, due to limitations imposed by bearing strength and service life, as well as installation requirements such as the parallelism of the rotating shaft and bearings, existing moving grinding disc speeds cannot be excessively high, limiting grinding efficiency. This makes existing grinding equipment difficult to achieve the higher precision grinding requirements for nanoclay, mineral powder, and flour. Summary of the Invention

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] A double-action vortex mill of this embodiment, such as Figures 1 to 4 As shown, it includes a turntable mechanism 2 and a rotary knife mechanism 3. The turntable mechanism 2 includes a first disk body 21 and a first driving mechanism 22 for driving the first disk body 21 to rotate. The first disk body 21 is provided with a concentrically arranged multi-layer annular target liner 23. The side wall of the annular target liner 23 is provided with a target tooth 231. A grinding channel 232 is formed between each two adjacent layers of the annular target liner 23. The annular target liner 23 is provided with a notch 233, so that multiple grinding channels 232 are connected. Each layer of the annular target liner 23 can be an overall annular with an opening on the side wall, or can be a multi-segment arc-shaped liner distributed at intervals.

[0037] The rotary cutter mechanism 3 includes a second disk body 31 and a second driving mechanism 32 for driving the second disk body 31 to rotate. The first disk body 21 and the second disk body 31 are both circular disks, arranged facing each other and arranged in opposite directions, that is, one of the first disk body 21 and the second disk body 31 rotates clockwise and the other rotates counterclockwise. The second disk body 31 is provided with a plurality of grinding members 33, and the grinding members 33 are located in the grinding channel 232. There is a gap between the grinding members 33 and the side wall of the annular target liner 23. The gap is left to generate a vortex during rotation, and particles collide with each other and collide with the target teeth 231 to break up and grind. Each grinding channel 232 is provided with a plurality of grinding members 33 arranged separately, and the grinding members 33 in the plurality of grinding channels 232 are aligned with each other. Figure 2 Each grinding channel 232 has four grinding members 33 , and the grinding members 33 are cylindrical structures protruding from the second plate 31 . Figure 1 and Figure 3 The annular target liner 23 and the grinding piece 33 cooperate slightly differently, but the principles are the same.

[0038] In this embodiment, the first disk body 21 is connected to the first rotating shaft 24, and the first driving mechanism 22 is used to drive the first rotating shaft 24 to rotate; the second disk body 31 is connected to the second rotating shaft 34, and the second driving mechanism 32 is used to drive the second rotating shaft 34 to rotate. The first driving mechanism 22 and the second driving mechanism 32 can adopt a commonly used motor combined with a pulley structure.

[0039] This embodiment further includes a housing 1 , which is provided with a grinding chamber 11 , in which the first disc 21 and the second disc 31 are located. The first rotating shaft 24 and the second rotating shaft 34 are rotatably and sealingly mounted on the housing 1 via bearings 12 .

[0040] In this embodiment, the innermost grinding channel 232 is connected to a feed structure comprising a feed channel 35 disposed in the middle of the second rotating shaft 34 and a feed cavity 13 formed by the first and second disc bodies 21 and 31 facing each other. Specifically, the second rotating shaft 34 is a tubular structure, with the feed channel 35, the feed cavity 13, and the notch 233 of the innermost grinding channel 232 interconnected in sequence. In practice, a similar feed channel 35 could also be disposed on the first rotating shaft 24.

[0041] In this embodiment, the outermost grinding channel 232 is connected to a discharge structure comprising a discharge pipe 4 and a Laval nozzle 5 disposed therein. The discharge pipe 4 communicates with the outermost grinding channel 232. A classifier 6 is disposed adjacent to the material receiving structure and comprises a hopper 61, a fine material suction pipe 62 at the top of the hopper 61, and a coarse material lifting pipe 63 at the bottom of the hopper 61. The top of the hopper 61 is connected to the discharge pipe 4, and the coarse material lifting pipe 63 communicates with the feed structure.

[0042] Specifically, the outer end of the feed channel 35 is connected to the outside atmosphere and is provided with a feed conveyor 7 and a screw feeder 8. When in use, the raw material enters the screw feeder 8 from the feed conveyor 7, and then enters the feed channel 35 of the second rotating shaft 34. The first disc 21 and the second disc rotate in opposite directions to generate a vortex centrifugal force, which has a certain suction effect on the raw material in the feed channel 35. The raw material enters the feed cavity 13 between the first disc 21 and the second disc 31, as shown in FIG. Figure 2 The solid arrow indicates the direction of the raw material entering the grinding channel 232 from the notch 233 of the innermost annular target liner 23. The raw material is then ground from the inside out through multiple layers of the grinding channel 232. The notches 233 of each layer of the annular target liner 23 are staggered, extending the grinding path of the raw material in the grinding channel 232. The ground raw material flows out from the notch 233 of the outermost annular target liner 23. The Laval nozzle 5 accelerates the material to supersonic speed and flows through the discharge pipe 4 to the classifier 6. In the classifier 6, coarse particles sink upon impact with the wall and are returned to the feed channel 35 via the coarse material lifting pipe 63 for further grinding. Fine particles are sucked upward by the material suction pipe.

As for the other modules, existing equipment can be directly purchased from outside, and each module is connected by a pipeline combined with a delivery pump to transfer the material. The details are not elaborated here. This embodiment is intended to demonstrate the application of a double-action vortex machine in the production line of nano-modified clay.
