If a coarse-grained slurry is desired, the material only needs to be ground once. However, if a different particle size is required, the slurry that does not meet the requirements must be reintroduced into the grinding device for further grinding, repeating this process until the desired particle size is obtained. Multiple grinding cycles result in long grinding times and low production efficiency. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] The embodiments of this utility model are described below with reference to Figures 1 to 4.
[0031] According to an embodiment of the present invention, a slurry grinding mechanism is provided, comprising: a housing 1 and a grinding assembly 2.
[0032] Specifically, a grinding chamber is provided inside the housing 1. The grinding assembly 2 includes a first grinding element 201 and a second grinding element 202. The first grinding element 201 is rotatably disposed inside the grinding chamber, and the second grinding element 202 is movably disposed inside the grinding chamber. The second grinding element 202 can move towards or away from the feed inlet 6. The second grinding element 202 is sleeved on the outer periphery of the first grinding element 201, and a grinding gap exists between the first grinding element 201 and the second grinding element 202. Grinding teeth 3 are provided on the outer peripheral surface of the first grinding element 201, and mating teeth 4 are provided on the side of the second grinding element 202 facing the first grinding element 201. The density of the grinding teeth 3 gradually increases along the direction from the feed inlet 6 to the discharge outlet 7.
[0033] In this embodiment, a grinding chamber is provided inside the housing 1. The upper and lower ends of the housing 1 are respectively the inlet 6 and the outlet 7, which are connected to the grinding chamber. The first grinding element 201 is rotatably disposed in the grinding chamber. Grinding teeth 3 are provided on the outer peripheral surface of the first grinding element 201. The density of the grinding teeth 3 on the first grinding element 201 gradually increases along the direction from the inlet 6 to the outlet 7. The second grinding element 202 is movably disposed in the grinding chamber and is slidably connected to the inner wall of the grinding chamber. Part 202 is fitted onto the first grinding part 201. The side of the second grinding part 202 facing the first grinding part 201 has mating teeth 4. The second grinding part 202 and the first grinding part 201 are in clearance fit. The gap between the second grinding part 202 and the first grinding part 201 is constructed as a grinding gap. The material entering the grinding chamber from the feed port 6 will enter the grinding gap. The rotation of the first grinding part 201 drives the grinding teeth 3 to rotate. The mating teeth 4 can cooperate with the grinding teeth 3 to grind the material. After passing through the grinding gap, the material is discharged from the grinding chamber through the discharge port 7. The second grinding component 202 can move in a direction close to or away from the feed inlet 6 under external force, thereby driving the mating teeth 4 to move. When a slurry with a larger particle size is required, the second grinding component 202 is driven to move, so that the mating teeth 4 and the grinding teeth 3 with a smaller density are mated and ground. When a slurry with a smaller particle size is required, the mating teeth 4 and the grinding teeth 3 with a larger density are mated and ground. By adjusting the position of the second grinding component 202, slurries with different particle sizes can be obtained.
[0034] Specifically, as shown in Figure 2, the first grinding part 201 has a truncated cone structure, and the inner hole of the second grinding part 202 is also a tapered hole.
[0035] It should be noted that by setting grinding teeth 3 with gradually increasing density on the surface of the first grinding part 201, and simultaneously setting a movable second grinding part 202, the mating teeth 4 of the second grinding part 202 can be moved to match the grinding teeth 3 of different densities, so that slurries of different particle sizes can be ground. This eliminates the need for repeated grinding to obtain slurries of different particle sizes, reduces grinding time, improves grinding efficiency, expands application scenarios, and enhances practicality.
[0036] In one embodiment, the first grinding member 201 has a first grinding toothed ring 2011, a second grinding toothed ring 2012, and a third grinding toothed ring 2013. The first grinding toothed ring 2011, the second grinding toothed ring 2012, and the third grinding toothed ring 2013 are detachably connected to each other. The first grinding toothed ring 2011 is disposed on the side near the feed inlet 6, the third grinding toothed ring 2013 is disposed on the side near the discharge outlet 7, and the second grinding toothed ring 2012 is disposed between the first grinding toothed ring 2011 and the third grinding toothed ring 2013. The first grinding toothed ring 2011, the second grinding toothed ring 2012, and the third grinding toothed ring 2013 have a first grinding tooth 301, a second grinding tooth 302, and a third grinding tooth 303, respectively. The density of the first grinding tooth 301, the second grinding tooth 302, and the third grinding tooth 303 increases sequentially.
[0037] In this embodiment, as shown in Figures 2 and 3, the first grinding tooth ring 2011, the second grinding tooth ring 2012, and the third grinding tooth ring 2013 are detachably connected in sequence. The first grinding tooth 301 on the first grinding tooth ring 2011 has the highest density, followed by the second grinding tooth 302 on the second grinding tooth ring 2012, and the third grinding tooth 303 on the third grinding tooth ring 2013 has the lowest density. The mating tooth 4 can simultaneously mate with the first grinding tooth 301, the second grinding tooth 302, and the third grinding tooth 303, resulting in the smallest particle size of the ground slurry. The mating tooth 4 can also simultaneously mate with the first grinding tooth 301 and the second grinding tooth 302, resulting in a smaller particle size of the ground slurry. The mating tooth 4 can also simultaneously mate with the first grinding tooth 301, the second grinding tooth 302, and 2 / 3 of the third grinding tooth 303. The specific mating method of the mating tooth 4 with the grinding tooth 3 needs to be determined according to the required slurry and is not specifically limited here. By detachably connecting the first grinding tooth ring 2011, the second grinding tooth ring 2012, and the third grinding tooth ring 2013, it is convenient to disassemble and replace any one or more of the grinding teeth 3 of the first grinding tooth ring 2011, the second grinding tooth ring 2012, and the third grinding tooth ring 2013 when they are severely worn, without having to replace the entire first grinding part 201, thus avoiding waste.
[0038] In one embodiment, the end face of the first grinding tooth ring 2011 facing the feed port 6 has at least two arc-shaped protrusions 20111, the outer surface of the arc-shaped protrusions 20111 has first grinding teeth 301, and there is a feed gap between adjacent arc-shaped protrusions 20111, through which the material enters the grinding gap.
[0039] In this embodiment, as shown in FIG2, the end face of the first grinding tooth ring 2011 facing the feed port 6 has two arc-shaped protrusions 20111. The two arc-shaped protrusions 20111 are arranged opposite to each other, and there is a feed gap between the two arc-shaped protrusions 20111. The first grinding tooth ring 2011 has a groove, which is connected to the feed gap. The material entering the grinding chamber from the feed port 6 will enter the groove and enter the grinding gap through the feed gap. The material entering the grinding gap will be ground by the grinding teeth 3 and the mating teeth 4.
[0040] In one embodiment, the diameter of the arcuate convex edge 20111 gradually decreases from the middle to both ends.
[0041] In this embodiment, as shown in Figure 2, the arc-shaped protrusion 20111 has a crescent-shaped structure. The crescent-shaped structure facilitates the entry of materials into the grinding gap, and the arc-shaped protrusion 20111 can play a guiding role.
[0042] In one embodiment, the mating tooth 4 includes a first mating tooth 401, a second mating tooth 402, and a third mating tooth 403, which are respectively staggered with the first grinding tooth 301, the second grinding tooth 302, and the third grinding tooth 303.
[0043] In this embodiment, as shown in FIG4, the first mating tooth 401 mates with the first grinding tooth 301, and the tooth shape direction of the first mating tooth 401 and the first grinding tooth 301 is opposite. The second mating tooth 402 mates with the second grinding tooth 302, and the tooth shape direction of the second mating tooth 402 and the second grinding tooth 302 is opposite. The third mating tooth 403 mates with the first grinding tooth 301, and the tooth shape direction of the third mating tooth 403 and the third grinding tooth 303 is opposite.
[0044] In one embodiment, the second grinding member 202 has a handle 5, which can drive the second grinding member 202 to move under the action of external force, so that the first mating tooth 401 engages with the first grinding tooth 301 and / or the second grinding tooth 302, the second mating tooth 402 engages with the second grinding tooth 302 and / or the third grinding tooth 303 / first grinding tooth 301, and the third mating tooth 403 engages with the third grinding tooth 303 and / or the second grinding tooth 302.
[0045] In this embodiment, as shown in Figure 1, the handle 5 is disposed outside the housing 1. The second grinding member 202 has a blocking wall 9 that is slidably connected to the outer wall of the housing 1. The handle 5 is fixedly connected to the blocking wall 9. A sealing structure is provided between the blocking wall 9 and the housing 1 to prevent material leakage from the gap between the blocking wall 9 and the housing 1. By moving the second grinding member 202, the first mating tooth 401 can be made to engage only with the first grinding tooth 301 or only with the second grinding tooth 302. Alternatively, the first mating tooth 401 can be moved to the space between the first grinding tooth 301 and the second grinding tooth 302, engaging with both simultaneously. The same applies to the second mating tooth 402 and the third mating tooth 403, which will not be described in detail here. The sealing structure can be a sealing strip, which can provide a certain damping effect to the second grinding member 202 to prevent the second grinding member 202 from moving without driving force.
[0046] It should be noted that the slurry grinding mechanism is set in a horizontal direction, not in the vertical direction shown in Figure 1. Figure 1 is only a schematic diagram of the slurry grinding mechanism and does not represent the actual orientation of the slurry grinding mechanism.
[0047] In this embodiment, as shown in Figures 1 and 4, the handle 5 is a handle.
[0048] In one embodiment, the first grinding tooth 301 and the second grinding tooth 302 are alternately arranged, and the second grinding tooth 302 and the third grinding tooth 303 are alternately arranged.
[0049] In this embodiment, the first grinding tooth 301, the second grinding tooth 302, and the third grinding tooth 303 are rhomboid teeth (not shown). The rhomboid teeth generate high-frequency oscillations during grinding. The oscillations exert tensile and compressive forces on the particles in the material, causing the particles to break and fragment. The high-frequency oscillations also generate strong turbulence in the grinding gap. The strong turbulence and related impact effects in the grinding gap help to improve the grinding and mixing effect.
[0050] In this embodiment, the first grinding element 201 is detachably connected to the motor shaft 8. The first grinding element 201 is sleeved on the motor shaft 8, and the motor shaft 8 can drive the first grinding element 201 to rotate.
[0051] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
