Description

Technical Field

[0001] This utility model relates to the field of dispersion technology, and in particular to a high-shear dispersion machine. Background Technology

[0002] A high-shear disperser is a type of equipment used to process various materials. Its main function is to stir solid particles or liquid suspensions to disperse them in a medium and ensure uniform dispersion of materials through high shear force. This type of equipment is widely used in industries such as chemical, food processing, pharmaceutical, coating, and ink.

[0003] A search revealed Chinese Patent Publication No. CN217989078U, which discloses a high-shear dispersion emulsifier, including a drive motor and a column. The drive motor is located at the top of the column, and a fixed base is provided at the bottom of the column. A fixed shaft is provided at the output end of the drive motor, and a reinforcing structure is provided on the cylindrical surface of the fixed shaft. A balancing structure is provided in the middle of the reinforcing structure, and the balancing structure is connected to the middle of the reinforcing structure. The reinforcing structure includes two fixed turntables, which are located at the upper and lower ends of the fixed shaft, respectively. This high-shear dispersion emulsifier, with its first and second connecting rods unfolded, can reinforce the fixed shaft and the material cylinder, preventing significant swaying of the material cylinder or the fixed shaft. The material cylinder is more stably fixed, ensuring that the support frame is always in a horizontal position. This ensures that the support frame fits snugly against the inner wall of the material cylinder, preventing the support frame from deflecting, making it quite practical.

[0004] However, the fixed turntable in this application lacks a self-locking structure. Therefore, in order to fix the barrel, it is necessary to use a reinforcement structure and a fixed base together. However, the structure of the fixed base is fixed, so it can only be effectively fixed for barrels that meet the size of the fixed base, resulting in poor performance and inapplicability to barrels of different specifications. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-shear disperser, which aims to improve the problem that the existing technology can only effectively fix material cylinders that conform to the size of the fixed base, and cannot be applied to material cylinders of different specifications.

Multiple meshing gears two mesh with the outer circumference of the meshing gear one. The multiple meshing gears two mesh with the inner wall of the fixed disk. A stirring rod is provided at the bottom end of the meshing gear one. A spiral rod is provided at the bottom end of each of the multiple meshing gears two.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a high-shear disperser, comprising a base plate 1, a mixing mechanism 2 disposed on the upper side of the base plate 1, a fixed seat 3 fixedly connected to the top wall of the base plate 1, a chamber 12 formed inside the fixed seat 3, a bevel gear 11 penetrating through the outer wall of the fixed seat 3, the bevel gear 11 penetrating into the chamber 12 and meshing with a bevel gear 13, a turntable 14 fixedly connected to the top of the bevel gear 13, a plurality of guide grooves 18 formed on the top wall of the turntable 14, connecting rods 15 slidably connected in each of the plurality of guide grooves 18, fixed rods 16 fixedly connected to the middle of each of the plurality of connecting rods 15, and the near ends of the plurality of fixed rods 16 penetrating into the fixed seat 3. The wall is fixedly connected to a clamping plate 6. The upper inner wall of the clamping plate 6 is rotatably connected to a rotating shaft 7. The middle of the rotating shaft 7 is fixedly connected to a locking block 8. One end of the torsion spring 9 is fixedly connected to both sides of the locking block 8. The other end of the torsion spring 9 is fixedly connected to the locking block 8. The outer wall of the fixed base 3 is fixedly connected to a fixed shell 4. The top wall of the fixed shell 4 is rotatably connected to a worm gear 5. The bottom end of the worm gear 5 passes through the fixed shell 4 and meshes with a worm wheel 10. The end of the bevel gear 11 away from the bevel gear 2 13 is fixedly connected to the worm wheel 10. The top wall of the chamber 12 is provided with multiple limiting grooves 2 17. The top ends of multiple connecting rods 15 are slidably connected in the limiting grooves 2 17.

[0041] Specifically, the operator can rotate the worm gear 5 to drive the meshing worm wheel 10 and the bevel gear 11 connected to the worm wheel 10 to rotate. The bevel gear 11 can drive the meshing bevel gear 13 and the turntable 14 fixed on the bevel gear 13 to rotate. When the turntable 14 rotates, it will drive the guide groove 18 set on the turntable 14 to move. Since the two ends of the guide groove 18 are at different distances from the center, the rotation of the guide groove 18 can drive the connecting rod 15 to move. And since the top of the connecting rod 15 slides in the limiting groove 17, the limiting groove 17 will limit the connecting rod 15, so that the connecting rod 15 will move linearly along the limiting groove 17 under the action of the guide groove 18, thereby enabling multiple connecting rods 15 to drive The clamping plate 6 moves closer to or further away from the mixing tank simultaneously; and the locking block 8 set on the clamping plate 6 can be locked into the groove on the matching mixing tank for positioning, thereby ensuring the stability during mixing; when using an incompatible mixing tank, the locking block 8 can be rotated to make it perpendicular to the horizontal plane. Since the locking block 8 will pull the torsion spring 9 when rotating, when the clamping plate 6 clamps and limits it, the locking block 8 will also press the mixing tank under the action of the torsion spring 9, thereby limiting and fixing the incompatible mixing tank, thus achieving the effect of mixing and dispersing applicable to mixing tanks of different specifications; and since the worm 5 and worm wheel 10 have self-locking properties, it can prevent the clamping plate 6 from moving during the dispersion process of the device, thereby affecting the positioning effect of the mixing tank.

[0042] Reference Figure 1 , Figure 3 and Figure 4The mixing mechanism 2 includes an electric push rod 201, which is fixedly connected to the rear side of the top wall of the base plate 1. The output end of the electric push rod 201 is fixedly connected to a top plate 203. A fixed disk 205 is fixedly connected to the front side of the bottom wall of the top plate 203. A servo motor 204 is fixedly connected to the front side of the top wall of the top plate 203. The output end of the servo motor 204 passes through the top plate 203 and the fixed disk 205 and is fixedly connected to a meshing gear 208. Multiple meshing gears 209 mesh around the outer periphery of the meshing gear 208. The fixed disk 205... The inner wall of plate 5 is provided with an internal gear ring, and multiple meshing gears 209 mesh with the inner wall of the fixed plate 205. The bottom end of the meshing gear 208 is provided with a stirring rod 207, and the bottom end of the multiple meshing gears 209 is provided with a spiral rod 206. The inner top wall of the fixed plate 205 is provided with a limiting groove 210, and the top ends of the multiple meshing gears 209 are rotatably connected in the limiting groove 210. The rear sides of the top wall of the bottom plate 1 are fixedly connected with telescopic rods 202, and the top ends of the two telescopic rods 202 are fixedly connected to the bottom wall of the top plate 203.

[0043] Specifically, the operator can drive the top plate 203 and the connecting parts connected to the top plate 203 to move up and down by activating the electric push rod 201; during the movement, the telescopic rod 202 can limit and support the top plate 203, thereby ensuring the stability of the movement of the top plate 203; when the top plate 203 drives the stirring rod 207 deeper into the mixing tank, the operator can activate the servo motor 204 to drive the connected meshing gear 1 208 to rotate; the meshing gear 1 208 can drive the multiple meshing gears 209 to rotate, since the multiple meshing gears 209 also mesh with the inner wall of the fixed plate 205. Therefore, under the action of the fixed disk 205, the second meshing gear 209 can rotate around the first meshing gear 208 while rotating on its own axis; thus, the multiple screw rods 206 can rotate on their own axis while revolving around the first gear, and together with the stirring rod 207, the stirring area can be increased, and under the action of the screw rods 206, the materials in the upper and lower layers can be mixed, thereby effectively improving the efficiency of stirring and dispersing materials; and by setting the limiting groove 210 and placing the top of the second meshing gear 209 in the limiting groove 210, the limiting groove 210 can limit the second meshing gear 209, ensuring the stability of the operation of the second meshing gear 209.

[0044] Reference Figure 3 The first bevel gear 11 is rotatably connected to the inner side wall of the chamber 12, and the second bevel gear 13 is rotatably connected to the bottom wall of the chamber 12.

[0045] Specifically, by limiting the bevel gear 11 and bevel gear 2 13, the stability of the meshing transmission of bevel gear 11 and bevel gear 2 13 can be guaranteed.

[0046] Reference Figure 3The top ends of multiple spiral rods 206 all penetrate into the meshing gear 209 and are threadedly connected to the meshing gear 209; the top end of stirring rod 207 penetrates into the meshing gear 1 208 and is threadedly connected to the meshing gear 1 208.

[0047] Specifically, by threading the screw rod 206 and the stirring rod 207 to the meshing gear 209 and the meshing gear 208 respectively, the screw rod 206 and the stirring rod 207 can be disassembled and installed according to actual needs.

[0048] Working principle: In actual use, the operator can rotate bevel gear 11 to drive bevel gear 13 to rotate; bevel gear 13 drives turntable 14 to rotate, and through the guide groove 18 on turntable 14, it drives connecting rod 15 to move. Since connecting rod 15 penetrates the inner wall of fixed base 3, it is limited by fixed base 3, thus allowing multiple connecting rods 15 to drive clamping plate 6 to move closer or further away simultaneously; and the locking block 8 set on clamping plate 6 can be locked into the groove on the matching mixing tank for positioning, thereby ensuring the stability during mixing; when using an incompatible mixing tank, The clamping block 8 can be rotated to be perpendicular to the horizontal plane, so that it can be clamped and limited by the clamping plate 6, thereby achieving the effect of being applicable to different sizes of mixing tanks; in addition, by starting the servo motor 204, the connected meshing gear 1 208 can be driven to rotate; the meshing gear 1 208 can drive the meshing gear 209 to rotate, and under the action of the fixed plate 205, the meshing gear 209 can rotate around the meshing gear 1 208; thus, the multiple spiral rods 206 rotate on their own axis while revolving around the revolution, and together with the stirring rod 207, the efficiency of stirring and dispersing materials can be effectively improved.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
