Description

Technical Field

[0001] This utility model relates to the field of centrifuge vibration reduction technology, and in particular to a centrifuge for the production of edible butter. Background Technology

[0002] In edible butter production, centrifuges need to operate at high speeds to separate cream and whey through centrifugal force. Their operational stability directly affects separation efficiency, product quality, and equipment lifespan. However, existing centrifuge vibration damping solutions have significant shortcomings, which have become a key issue restricting production.

[0003] When a centrifuge is running, the rotational speed increases from the low speed during startup to the high speed during operation, resulting in vibrations of different frequencies and amplitudes. When the rotational speed is low, the vibration frequency is close to the equipment's resonant frequency. At this time, reducing the damping resistance can prevent excessive damping from amplifying resonance and prevent the amplitude from soaring, ensuring a smooth startup / shutdown process. When the rotational speed is high, the vibration frequency increases, and the amplitude is prone to fluctuations due to rotor imbalance. At this time, increasing the damping resistance can enhance the energy dissipation capacity of the damping, quickly absorb high-frequency vibration energy, stabilize the amplitude within a certain range, and prevent vibration from being transmitted to the separation chamber and causing disc collisions.

[0004] Currently, centrifuges used in butter production mostly employ single-layer rubber shock-absorbing pads or simple spring shock-absorbing designs. The shock-absorbing mechanism is relatively traditional and lacks damping adjustment function. It is impossible to dynamically adjust the shock-absorbing parameters according to changes in centrifuge speed and load. The centrifuge is prone to "resonance phenomenon" when starting and stopping. When the buffer force is too soft, it will lead to uncontrolled vibration. When the buffer force is too hard, it will cause resonance or component damage. Therefore, a centrifuge for edible butter production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a centrifuge for edible butter production, aiming to solve the problem that the buffering and shock absorption resistance of existing butter centrifuges cannot be dynamically adjusted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a centrifuge for producing edible butter, comprising a base, a centrifuge body fixedly connected to the base via support legs, a dynamic adjustment buffer device provided on the base, and a vibration monitoring sensor fixedly connected to the bottom of the centrifuge body; the dynamic adjustment buffer device includes an adjusting screw and a driving device, the bottom end of the adjusting screw being rotatably connected to the centrifuge body, a limiting base being threadedly connected to the surface of the adjusting screw, a buffer assembly being provided on the limiting base, and the driving device being used to drive the adjusting screw to rotate.

[0007] As a further description of the above technical solution:

[0008] The number of adjusting screws is set to two sets, and the two sets of adjusting screws are symmetrically distributed with the center line of the limiting base as the axis of symmetry. The top end of the adjusting screw is fixedly connected to a limiting plate, and the vibration monitoring sensor is set as a charge output piezoelectric sensor.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes a damper, one end of which is fixedly mounted on a limiting base by bolts, and the other end of which is fixedly connected to a connecting base by bolts. A pressure plate is fixedly connected to the connecting base.

[0011] As a further description of the above technical solution:

[0012] A limiting telescopic rod is fixedly connected to the limiting base, and the telescopic end of the limiting telescopic rod is fixedly connected to the connecting base.

[0013] As a further description of the above technical solution:

[0014] A buffer pad is fixedly connected to the pressure plate, and the top of the pressure plate is in contact with the bottom of the centrifuge body.

[0015] As a further description of the above technical solution:

[0016] Both sides of the connecting base are fixedly connected to reinforcing rods, and the other end of the reinforcing rods is fixedly connected to the surface of the pressure plate.

[0017] As a further description of the above technical solution:

[0018] The driving device includes a drive motor, one end of which is fixedly connected to the base. The output shaft of the drive motor is fixedly connected to a connecting rod, and a worm gear is fixedly connected to the connecting rod. A worm wheel meshes with the worm gear.

[0019] As a further description of the above technical solution:

[0020] The end of the connecting rod is rotatably connected to the machine base, and the interior of the worm gear is fixedly connected to the surface of the adjusting screw.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the vibration monitoring sensor monitors the centrifuge body in real time while assisting the dynamic adjustment buffer device to dynamically adjust the buffering force. By changing the pre-compression amount of the damping through the dynamic adjustment buffer device, the starting point of the buffering process is changed, thereby achieving the effect of automatically adjusting the buffering resistance. This allows the overall buffer structure to dynamically adjust the damping parameters according to the centrifuge speed and load changes, avoiding resonance when the centrifuge starts or stops, and preventing vibration from getting out of control due to too soft buffering force, or resonance or component damage due to too hard buffering force.

[0023] 2. In this utility model, multiple worm gears and multiple corresponding worm wheels are set on a connecting rod, which can realize the effect of synchronous transmission of multiple sets of adjusting screws to rotate, thereby realizing the synchronous dynamic adjustment of the buffer force of multiple sets of buffer components. At the same time, one worm gear corresponds to two sets of worm wheels for transmission, thereby realizing the synchronous adjustment of two symmetrical adjusting screws at the same set of buffer components, thereby improving the stability of the buffer adjustment of the same set of buffer components.

[0031] 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.

[0032] Reference Figures 1-2 The embodiment provided by this utility model includes: a base 1, on which a centrifuge body 3 is fixedly connected via support legs 2; a dynamic adjustment buffer device 4 is provided on the base 1; a vibration monitoring sensor 5 is fixedly connected to the bottom of the centrifuge body 3, and the vibration monitoring sensor 5 is a charge output piezoelectric sensor; the dynamic adjustment buffer device 4 includes two sets of symmetrically distributed adjusting screws 41 and a drive device 44; the bottom end of the adjusting screw 41 is rotatably connected to the centrifuge body 3; a limiting base 42 is threadedly connected to the surface of the adjusting screw 41; the two sets of adjusting screws 41 are symmetrically distributed about the center line of the limiting base 42, thereby synchronously controlling the limiting base 42 to achieve stable adjustment of the height of the limiting base 42, and simultaneously limiting the limiting base 42 so that it can only move linearly up and down; a buffer assembly 43 is provided on the limiting base 42; and the drive device 44 is used to drive the adjusting screws. 41. The vibration monitoring sensor 5 is connected to the alarm module and the dynamic adjustment buffer device 4. It monitors the centrifuge body 3 in real time and assists the dynamic adjustment buffer device 4 in dynamically adjusting the buffering force. Combined with the alarm module, it issues an audible and visual alarm when the amplitude exceeds the predetermined value and sends a fault signal to the central system to remind the staff to check the equipment. This avoids the situation where minor vibration abnormalities cannot be detected in time, and irreversible problems such as disc deformation and bearing damage have occurred when obvious faults occur, thus reducing downtime losses. By changing the pre-compression amount of the damping through the dynamic adjustment buffer device 4, the starting point of the buffering process is changed, thereby achieving the effect of automatically adjusting the buffering resistance. This allows the overall buffering structure to dynamically adjust the damping parameters according to the centrifuge speed and load changes, avoiding resonance phenomena that are easy to occur when the centrifuge starts or stops. It also avoids problems such as uncontrolled vibration due to too soft buffering force or resonance or component damage due to too hard buffering force.

[0033] Reference Figure 3 A limiting plate 45 is fixedly connected to the top of the adjusting screw 41 to limit the adjustment height of the limiting base 42, so as to avoid the problem that the limiting base 42 will disengage from the adjusting screw 41 due to excessive adjustment.

[0034] Reference Figure 4-5The buffer assembly 43 includes a damper 431. One end of the damper 431 is fixedly mounted on the limiting base 42 by bolts, and the other end of the damper 431 is fixedly connected to the connecting base 432 by bolts. A pressure plate 433 is fixedly connected to the connecting base 432. A limit telescopic rod 434 is fixedly connected to the limiting base 42. The fixed end of the limit telescopic rod 434 is fixedly connected to the limiting base 42, and the telescopic end of the limit telescopic rod 434 is fixedly connected to the connecting base 432. The limit telescopic rod 434 is used to limit the pressure plate 433 to perform linear buffering. A buffer pad is fixedly connected to the pressure plate 433. The top of the pressure plate 433 is in contact with the bottom of the centrifuge body 3. The pressure plate 433 is in direct contact with the centrifuge body 3 during operation. The buffer pad can further protect the pressure plate 433 and the centrifuge body 3. Reinforcing rods 435 are fixedly connected to both sides of the connecting base 432 to strengthen the connection between the pressure plate 433 and the connecting base 432, so that the amplitude of the pressure plate 433 is better transmitted to the damper 431 on the connecting base 432. The other end of the reinforcing rod 435 is fixedly connected to the surface of the pressure plate 433.

[0035] Reference Figure 4 The drive unit 44 includes a drive motor 441, one end of which is fixedly connected to the base 1. A connecting rod 442 is fixedly connected to the output shaft of the drive motor 441. A worm gear 443 is fixedly connected to the connecting rod 442, and a worm wheel 444 meshes with the worm gear 443. The end of the connecting rod 442 is rotatably connected inside the base 1. The interior of the worm wheel 444 is fixedly connected to the surface of the adjusting screw 41. Multiple sets of adjusting screws 41, limiting bases 42, and buffer assemblies 43 are provided for adjusting the bottom of the centrifuge body 3. The system provides stable buffering at multiple points. By setting multiple worm gears 443 and multiple corresponding worm wheels 444 on a connecting rod 442, it can achieve the effect of synchronously driving the rotation of multiple sets of adjusting screws 41, thereby enabling the synchronous dynamic adjustment of the buffering force of multiple sets of buffer components 43. At the same time, one worm gear 443 drives two sets of worm wheels 444, thereby enabling the synchronous adjustment of two symmetrical adjusting screws 41 at the same set of buffer components 43, thus improving the stability of the buffering adjustment of the same set of buffer components 43.

[0036] Working principle: When the centrifuge body 3 is working, it generates vibration and transmits the force to the pressure plate 433. The pressure plate 433 achieves the effect of buffering and shock absorption through the damper 431 on the connecting base 432. The vibration monitoring sensor 5 monitors the overall amplitude of the centrifuge body 3 and transmits the data to the central controller for analysis. Based on the amplitude, the controller controls the working state of the active motor 441. The output shaft of the active motor 441 drives the worm gear 443 on the connecting rod 442 to rotate. The worm gear 443 meshes with the worm wheel 444 and drives the limiting base 42 on the adjusting screw 41 to rotate and adjust. The limiting base 42 drives the damper 431 to adjust the height of the pressure plate 433 on the connecting base 432. By changing the pre-compression of the damper 431 through the mechanical structure, the buffering effect is changed. The system automatically adjusts the buffer resistance based on the centrifuge's speed and load, preventing resonance during centrifuge startup or shutdown. This avoids uncontrolled vibration due to excessively soft buffering force or resonance and component damage due to excessively hard buffering force. Simultaneously, the vibration monitoring sensor 5 monitors the centrifuge body 3 in real time, assisting the dynamic adjustment buffer device 4 in adjusting the buffering force. It also connects to an alarm module, triggering an audible and visual alarm when the amplitude exceeds a predetermined value and sending a fault signal to the central system. This alerts staff to inspect the equipment, preventing the failure to detect minor vibration anomalies in time, which could lead to irreversible problems such as disc deformation and bearing damage by the time obvious faults occur, thus reducing downtime losses.
