Description

Technical Field

[0001] This utility model relates to the technical field of fluid material homogenization equipment, and in particular to a homogenizer with adjustable gap. Background Technology

[0002] As a key piece of equipment for refining and dispersing materials, the core working principle of a homogenizer is to refine and uniformly disperse material particles through the high-speed relative motion between the rotor and stator, utilizing shearing, impact, and turbulence. The homogenization gap between the rotor and stator directly determines the homogenization effect. However, existing homogenizers have many shortcomings in practical applications:

[0003] Firstly, traditional homogenizers mostly adopt a fixed gap design. If it is necessary to adapt to materials with different viscosity or particle size requirements, the machine needs to be stopped to disassemble and replace parts, which is cumbersome and time-consuming. Some adjustable models can adjust the gap by manually turning the bolts, which lacks precise guidance and quantitative control, and is prone to gap deviation and unevenness in the circumferential direction, affecting the homogenization consistency of materials.

[0004] Secondly, the sealing structure design of the sliding fit between the stator and the stator base, and the through-hole between the main shaft and the stator base is unreasonable. Material leakage is prone to occur during high-pressure material handling and gap adjustment, which not only causes waste, but may also pollute the equipment environment.

[0005] Third, most equipment lacks real-time monitoring and automatic control functions, and gap adjustment relies on manual experience. It cannot be dynamically adjusted according to the material status, making it difficult to meet the needs of continuous and high-precision production.

[0006] Therefore, there is an urgent need for a homogenizer with stable structure, precise and convenient gap adjustment, reliable sealing, and a high degree of automation. Utility Model Content

[0008] This utility model achieves the above objectives through the following technical solutions:

[0009] A homogenizer with adjustable gap includes a base, a drive motor mounted on one end of the base, a bracket connected to the output end of the drive motor via bolts, a rotor assembly mounted on the output end of the drive motor, and a stator assembly mounted on the bracket away from the drive motor. The stator assembly is sleeved on the outside of the rotor assembly, forming a homogenization gap between the rotor assembly and the stator assembly. A gap adjustment assembly is mounted on the base. The gap adjustment assembly includes a fixing frame fixed to one end of the base via bolts. Concave plates are mounted at both ends of the fixing frame.

[0015] Furthermore, a mechanical seal is provided between the main shaft and the stator seat.

[0016] Furthermore, a control module is provided at one end of the bottom of the fixed frame, and a displacement sensor is provided at the middle of the bottom. The control module is electrically connected to the drive motor, the servo motor and the displacement sensor respectively.

[0017] Beneficial effects: This utility model has the following beneficial effects:

[0018] 1. Driven by a servo motor, the worm gear transmission, combined with two sets of stacked adjusting screws connected to the stator threads, allows for uniform gap adjustment without disassembly.

Combined with real-time monitoring by a displacement sensor, the adjustment accuracy is high and the circumferential gap is uniform.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Combination Figures 1 to 5 The homogenizer with adjustable gap shown includes a base 1. A drive motor 2 is mounted on one end of the base 1. A bracket 3 is bolted to the output end of the drive motor 2. A rotor assembly 4 is mounted on the output end of the drive motor 2. A stator assembly 5 is mounted on the end of the bracket 3 away from the drive motor 2. The stator assembly 5 is sleeved on the outside of the rotor assembly 4, forming a homogenization gap between the rotor assembly 4 and the stator assembly 5. A gap adjustment assembly 6 is mounted on the base 1. The gap adjustment assembly 6 includes a fixing frame 601, which is bolted to one end of the base 1, forming a stable connection with the base 1. Concave plates 602 are mounted at both ends of the fixing frame 601. A servo motor 603 is bolted to the outer end of each concave plate 602. A worm gear 604 is connected to the output end of the servo motor 603. The other end of the worm gear 604 is rotatably connected to one side wall of the concave plate 602. An adjusting screw 605 is rotatably connected between each concave plate 602 and the stator assembly 5. The rod 605 is symmetrically distributed with respect to the axis of the stator assembly 5, which can make the stator 503 bear the force evenly and avoid deviation during adjustment. A worm gear 606 is provided on one end of the adjusting screw 605. The worm 604 meshes with the worm gear 606 to drive the high-speed rotation of the servo motor 603 into the smooth movement of the adjusting screw 605, thereby improving the adjustment accuracy. The adjusting screw 605 is provided with a threaded section 607, which realizes the precise axial displacement of the stator 503 through threaded transmission, solving the problems of low accuracy and cumbersome operation of traditional manual adjustment.

[0031] The bracket 3 is connected to the base 1 at the bottom center by bolts to further stabilize the bracket 3. This can significantly reduce the vibration generated during the high-speed operation of the drive motor 2 and the gap adjustment process, avoid coaxiality deviation between the rotor assembly 4 and the stator assembly 5, thereby improving the stability of the homogeneous gap and ensuring the homogeneity of the material.

[0032] The rotor assembly 4 includes a main shaft 401, which is connected to the output end of the drive motor 2 via a coupling 402. A rotor 403 is provided at the end of the main shaft 401 away from the coupling 402. Several rotor teeth 404 are provided on the rotor 403, and the rotor teeth 404 are evenly distributed along the circumference of the rotor 403.

[0033] The stator assembly 5 includes a stator base 501, which is connected to the end of the support 3 via several connecting rods 502. A stator 503 is slidably connected to the end of the stator base 501 away from the support 3. Several stator teeth 504 are provided on the stator 503. The stator teeth 504 are evenly distributed along the circumference of the stator 503. The stator teeth 504 and the rotor teeth 404 are staggered to form multiple shearing surfaces. With high-speed relative motion, they can generate sufficient shearing and impact on the material, thereby improving the particle refinement effect.

[0034] The inner ring of the stator base 501 is evenly provided with several guide grooves 505, and the outer ring of the stator 503 is evenly provided with several guide blocks 506. The guide blocks 506 are adapted to the guide grooves 505 to form a precise guiding structure, ensuring that the stator 503 always remains coaxial with the rotor 403 when it moves, and avoiding uneven circumferential gaps. One end of the stator 503 is provided with a feed port 507, and the stator base 501 is provided with a discharge port 508.

[0035] The stator 503 has two sets of threaded holes 509. The two ends of the adjusting screw 605 are rotatably connected to the concave plate 602 and the stator seat 501 respectively through bearings. The threaded section 607 is threadedly connected to the threaded hole 509. The rotational motion of the adjusting screw 605 is converted into the axial linear motion of the stator 503 through threaded transmission, so as to achieve precise adjustment of the homogeneous gap. The stator 503 is provided with a sealing ring 510 on the outer ring of the stator tooth 504, which is tightly fitted with the inner wall of the stator seat 501 to form a sealing barrier, effectively preventing high pressure material from leaking from the sliding gap between the stator 503 and the stator seat 501.

[0036] A mechanical seal 7 is provided between the main shaft 401 and the stator seat 501 to prevent material leakage from the main shaft 401, thus avoiding material waste and environmental pollution.

[0037] A control module 8 is installed at one end of the bottom of the fixed frame 601, and a displacement sensor 9 is installed in the middle of the bottom. The displacement sensor 9 can collect the displacement data of the stator in real time. The control module 8 is electrically connected to the drive motor 2, the servo motor 603 and the displacement sensor 9 to form a closed-loop control system. The control module 8 can receive the real-time signal from the displacement sensor 9, calculate the current homogenization gap, and automatically control the start and stop of the servo motor 603 according to the preset value. At the same time, it can adjust the speed of the drive motor 2 to adapt to different materials. The control module 8 can also drive two sets of servo motors 603 to run simultaneously.
