Description

Technical Field

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

[0002] Multi-stage series high-shear dispersion and grinding mills are core equipment for achieving ultra-fine dispersion and homogenization of materials in fields such as lithium battery slurries, coatings, and nanomaterials. Through staged shearing and grinding by multiple sets of stator and rotor components, they can significantly improve the particle size uniformity and dispersion stability of materials. Traditionally, this type of equipment mainly consists of a grinding unit and a drive unit, both mounted on corresponding bases. However, in practical applications, it has been found that since most grinding units and drive units are not equipped with corresponding alignment devices during installation, there will still be some deviation in the actual position of the grinding unit and drive unit on the machine body after hoisting. This means that during further installation, it is necessary to manually pry and adjust the position repeatedly to align with the corresponding installation position on the machine base. This is not only time-consuming and labor-intensive, but also prone to causing the drive shaft concentricity to exceed the tolerance due to alignment deviation, resulting in problems such as large vibration during equipment operation and rapid wear of bearings and mechanical seals.

[0003] To address this, a multi-stage series high-shear dispersion and grinding mill is proposed. Utility Model Content

[0004] Based on this, it is necessary to provide a multi-stage series high-shear dispersion grinding machine to address the above-mentioned technical problems. The angle connection of the hoisting rod can be flexibly adjusted so that the angle between the connection and the alignment part can be adjusted. With the positioning arc block of the alignment part and the positioning groove of the alignment seat, the grinding unit, the drive unit and the machine base can be automatically guided to be precisely aligned during the hoisting process. This allows for more efficient alignment and placement during the hoisting stage, which facilitates subsequent assembly.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A multi-stage series high-shear dispersion grinding mill includes a base, a grinding unit and a drive unit are provided on the top of the base, and a transmission unit is provided inside the base. The drive unit drives the grinding unit to grind the material through the transmission unit. Mounting holes are provided at the four corners of the top of the base. A lifting rod is installed in the mounting hole. The lifting rod includes a connecting part and an aligning part. The connecting part and the aligning part are connected by an angle connecting part. The angle connecting part can be used to adjust the angle between the connecting part and the aligning part. An aligning rib is fixed in the middle of the connecting part. An aligning rib groove that matches the aligning rib is provided in the mounting hole. The grinding unit and the driving unit are both equipped with alignment seats at their bottoms. The surface of the alignment seats is provided with positioning grooves. The alignment of the grinding unit and the driving unit on the machine base can be achieved by the positioning grooves and the alignment parts.

[0006] Furthermore, the two ends of the alignment part are respectively provided with an adjustment arc-shaped seat and a positioning arc-shaped block, and the positioning arc-shaped block is adapted to the positioning groove.

[0007] Furthermore, a sliding groove is provided inside the positioning seat near the positioning groove, a locking ring is slidably provided in the sliding groove, a slider connected to the locking ring is also slidably provided in the sliding groove, and a locking groove adapted to the locking ring is provided on the surface of the positioning arc block.

[0008] Furthermore, an adjusting arc block is fixedly connected to the top of the connecting part, and four corner adjusting holes are opened on the surface of both the adjusting arc block and the adjusting arc seat, and four corner locking pins are inserted into the four corner adjusting holes.

[0009] Furthermore, one end of the four corner locking posts is fixed with a threaded connecting post, and the surface of the threaded connecting post is threaded with a fixing nut.

[0010] Furthermore, a lower locking nut is threaded to the bottom of the connecting part, and an upper locking nut is threaded to the top of the connecting part near the position of the adjusting arc block. A storage slot for storing the hoisting rod is provided inside the base.

[0011] Furthermore, a hoisting hole is provided in the middle of the alignment part.

[0012] Furthermore, the drive unit includes a drive motor, and the transmission unit includes a drive pulley and a driven pulley disposed inside the base. The bottoms of the drive pulley and the driven pulley are movably connected to the bottom wall of the base through a bearing seat. The output end of the drive motor is coaxially fixed with the drive pulley, and the driven pulley is connected to the drive pulley via a transmission belt.

[0013] Furthermore, the grinding unit includes a grinding tank and an upper grinding chamber, a middle grinding chamber, and a lower grinding chamber opened inside the grinding tank. Each of the upper grinding chamber, the middle grinding chamber, and the lower grinding chamber is provided with a stator and rotor assembly. Multiple stator and rotor assemblies are connected by a rotating shaft. The bottom end of the rotating shaft extends into the interior of the machine base and is fixed to the driven pulley.

[0014] Furthermore, the top of the grinding jar has a feeding valve port, and one side of the grinding jar has a discharge valve port. The stator and rotor assembly includes a stator grinding disc and a rotor grinding disc. The stator grinding disc is fixed in the corresponding upper grinding chamber, middle grinding chamber, or lower grinding chamber, and the rotor grinding disc is fixed to the surface of the rotating shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The multi-stage series high shear dispersion grinding machine provided by this utility model has an angle connection part of the hoisting rod that can flexibly adjust the angle between the connection part and the alignment part. With the positioning arc block of the alignment part and the positioning groove of the alignment seat, the grinding unit, the drive unit and the machine base can be automatically guided to be precisely aligned during the hoisting process. This allows for more efficient alignment and placement during the hoisting stage, which facilitates subsequent assembly. Furthermore, by sliding the locking ring inside the slide groove and engaging the locking groove on the positioning arc block, the auxiliary locking between the unit and the base can be completed simply by pushing the slider.

[0016] When the lifting boom is extended to a vertical position, it can also be used as a lifting support point, thus enabling the overall lifting and transportation of the equipment. At the same time, by loosening the upper and lower locking nuts, the height of the lifting holes on the lifting boom can be adjusted, allowing for adjustments based on the actual lifting situation, making it more practical.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] Example 1 Please refer to Figures 1-6 A multi-stage series high shear dispersion grinding mill includes a base 1, a grinding unit 2 and a drive unit 3 are provided on the top of the base 1, and a transmission unit 4 is also provided inside the base 1. The drive unit 3 drives the grinding unit 2 to grind the material through the transmission unit 4. Mounting holes 5 are provided at the four corners of the top of the base 1. A lifting rod 6 is installed in the mounting hole 5. The lifting rod 6 includes a connecting part 61 and an alignment part 62. The connecting part 61 and the alignment part 62 are connected by an angle connecting part 63. The angle between the connecting part 61 and the alignment part 62 can be adjusted by the angle connecting part 63. An alignment rib 617 is fixed in the middle of the connecting part 61. An alignment rib groove adapted to the alignment rib 617 is provided in the mounting hole 5. The bottom of the grinding unit 2 and the driving unit 3 are both equipped with an alignment seat 7. The surface of the alignment seat 7 is provided with a positioning groove 71. The positioning groove 71 and the alignment part 62 can realize the alignment and installation of the grinding unit 2 and the driving unit 3 on the base 1.

[0021] Because the multi-stage series high shear dispersion grinding machine of this utility model has the above structure, during the hoisting and positioning of the grinding unit 2 and the drive unit 3, the angle connecting part 63 of the hoisting rod 6 can adjust the included angle between the connecting part 61 and the alignment part 62, so that the alignment part 62 and the top surface of the base 1 remain parallel; at the same time, the alignment rib 617 in the middle of the connecting part 61 cooperates with the alignment rib groove in the mounting hole 5 to restrict the circumferential rotation of the hoisting rod 6, so that it maintains an axially fixed posture in the base 1, and this state satisfies the relative positional relationship between the alignment part 62 and the positioning groove 71 on the hoisting rod 6. In actual operation, when the grinding unit 2 is about to complete its descent, the alignment part 62 can be pre-embedded in the positioning groove 71 of the alignment seat 7 to form a guide and limit, thereby realizing the automatic pre-alignment of the grinding unit 2 and the drive unit 3 on the base 1, without the need for manual repeated prying and adjustment of the position after hoisting. The beneficial effects of this structure are: it significantly reduces the installation difficulty of large grinding units and drive units, avoids the problem of excessive concentricity of the drive shaft caused by manual alignment deviation, reduces the risk of vibration and mechanical seal wear during equipment operation from the source, and significantly shortens the downtime for installation and maintenance.

[0022] Example 2 The multi-stage series high-shear dispersion mill provided in Example 1 has been further optimized, specifically, as follows: Figure 3 As shown, the two ends of the alignment part 62 have an adjustment arc-shaped seat 620 and a positioning arc-shaped block 621, respectively, and the positioning arc-shaped block 621 is adapted to the positioning groove 71.

[0023] The positioning seat 7 has a sliding groove 72 located inside the positioning groove 71. A locking ring 73 is slidably disposed in the sliding groove 72. A slider 74 connected to the locking ring 73 is also slidably disposed in the sliding groove 72. The surface of the positioning arc block 621 has a locking groove 622 that is adapted to the locking ring 73.

[0024] Because the multi-stage series high shear dispersion grinding machine of this utility model has the above structure, when the positioning arc block 621 of the alignment part 62 is fully embedded in the positioning groove 71 of the alignment seat 7, the operator can push the slider 74 to drive the locking ring 73 in the slide groove 72 to slide laterally, so that the locking ring 73 is stuck in the locking groove 622 on the surface of the positioning arc block 621, thereby forming a rigid lock. It should be noted that the locking ring 73 only plays an auxiliary locking role. The main function of the alignment seat 7 is still for the alignment effect during assembly. Example 3 The multi-stage tandem high-shear dispersion mill provided in Embodiment 1 or 2 is further optimized, such as... Figure 6As shown, an adjusting arc block 610 is fixedly connected to the top of the connecting part 61. The surfaces of the adjusting arc block 610 and the adjusting arc seat 620 are provided with four corner adjusting holes 611, and four corner locking pins 612 are inserted into the four corner adjusting holes 611.

[0025] One end of the four corner locking post 612 is fixed with a threaded connecting post 613, and a fixing nut 614 is threadedly connected to the surface of the threaded connecting post 613.

[0026] The bottom of the connecting part 61 is also threaded with a lower locking nut 615, and the top of the connecting part 61 is threaded with an upper locking nut 616 near the position of the adjusting arc block 610. The base 1 has a storage slot 11 for storing the hoisting rod 6.

[0027] The alignment part 62 has a hoisting hole 623 in the middle.

[0028] Because the multi-stage series high shear dispersion grinding machine of this utility model has the above structure, by adjusting the relative position of the arc block 610 and the four corner adjustment holes 611 on the arc seat 620, the circumferential angle of the alignment part 62 relative to the connecting part 61 can be adjusted, and multi-position fixing can be achieved by the four corner locking pins 612 and the fixing nuts 614. In this way, the hoisting rod 6 can be switched between the alignment state and the overall hoisting state of the equipment.

[0029] At the same time, by loosening the lower locking nut 615 and the upper locking nut 616, the overall height of the lifting rod 6 can be adjusted in the vertical direction, making it convenient to lift the entire equipment according to the actual scenario. Example 4 The multi-stage series high-shear dispersion mill provided in Example 3 has been further optimized, such as... Figure 5 As shown, the drive unit 3 includes a drive motor 31, and the transmission unit 4 includes a drive pulley 41 and a driven pulley 42 disposed inside the base 1. The bottoms of the drive pulley 41 and the driven pulley 42 are movably connected to the bottom wall of the base 1 through a bearing seat. The output end of the drive motor 31 is coaxially fixed with the drive pulley 41, and the driven pulley 42 is connected to the drive pulley 41 via a transmission belt.

[0030] Because the multi-stage series high shear dispersion grinding machine of this utility model has the above structure, after the drive motor 31 starts, the power is transmitted to the drive pulley 41 through the output end. The drive pulley 41 drives the driven pulley 42 to rotate synchronously through the transmission belt. The driven pulley 42 then drives the rotating shaft 26 to rotate at high speed, thereby providing a stable driving force for the grinding unit 2. Example 5 The multi-stage series high-shear dispersion mill provided in Example 4 has been further optimized, such as... Figure 5 As shown, the grinding unit 2 includes a grinding tank 21 and an upper grinding chamber 22, a middle grinding chamber 23 and a lower grinding chamber 24 opened inside the grinding tank 21. Each of the upper grinding chamber 22, the middle grinding chamber 23 and the lower grinding chamber 24 is provided with a stator and rotor assembly 25. Multiple stator and rotor assemblies 25 are connected by a rotating shaft 26. The bottom end of the rotating shaft 26 extends into the interior of the base 1 and is fixed to the driven pulley 42.

[0031] The grinding jar 21 has a feeding valve at the top and a discharge valve on one side. The stator and rotor assembly 25 includes a stator grinding disc 250 and a rotor grinding disc 251. The stator grinding disc 250 is fixed in the corresponding upper grinding chamber 22, middle grinding chamber 23, or lower grinding chamber 24. The rotor grinding disc 251 is fixed to the surface of the rotating shaft 26.

[0032] Because the multi-stage series high shear dispersion and grinding mill of this utility model has the above structure, after the material enters from the feeding valve port at the top of the grinding tank 21, it passes through the upper grinding chamber 22, the middle grinding chamber 23 and the lower grinding chamber 24 in sequence. In each chamber, it undergoes high-speed shearing, collision and grinding with the corresponding stator and rotor assembly 25, realizing the step-by-step processing from coarse dispersion to ultrafine grinding. The rotating shaft 26 simultaneously drives the multi-stage stator grinding disc 250 and the rotor grinding disc 251 to rotate at high speed, so that the material forms a strong turbulent and shear flow field in the cavity, ensuring uniform particle size distribution and high dispersion stability; the processed material is finally discharged from the discharge valve on one side of the grinding tank 21. like Figure 1 and Figure 3 As shown, the lifting rod 6 is in the aligned state in this condition, as... Figure 2 and Figure 6 As shown, the lifting rod 6 is in the lifting state in this condition; When the hoisting rod 6 needs to assist in the alignment of the grinding unit 2 and the drive unit 3 during installation, the four corner locking pins 612 are removed, and the threaded connecting pins 613 are slid to the position of the four corner adjustment holes 611. This allows adjustment of the position between the alignment part 62 and the connecting part 61. After the alignment part 62 is placed in a horizontal position, the four corner locking pins 612 are pushed back to reset, and the angle is tightened using the fixing nuts 614. Then, the height of the connecting part 61 is adjusted to form the desired shape. Figure 1 After reaching the indicated state, rotate the upper locking nut 616 and the lower locking nut 615 to fix the height of the connecting part 61; When hoisting the grinding unit 2 and the drive unit 3, the positioning groove 71 on the base 7 can be aligned with the corresponding positioning arc block 621, which can play a positioning role and ensure that the grinding unit 2 and the drive unit 3 are in a precise state after hoisting, so that no further prying or adjustment is required during subsequent assembly. When the entire device needs to be hoisted, the alignment part 62 is adjusted to a vertical position, and then its height is adjusted. The entire device can then be hoisted from the four corners through the hoisting holes 623 on it.
