Abstract
Description
Technical Field
[0001] This application relates to the field of grinding apparatus, and more particularly to a colloid mill assembly. Background Technology
[0002] In related technologies, colloid mills use an electric motor to drive a moving grinding disc and a matching stationary grinding disc to rotate at high speed relative to each other. The moving grinding disc rotates at high speed while the stationary grinding disc remains stationary. When the material passes through the gap between the moving and stationary grinding discs, it is subjected to strong shearing force, friction, high-speed vortex and other physical actions, which effectively deagglomerates and disperses the material, achieving the effect of fully dissociating the material to a suitable particle size. However, when the colloid mill operates at a relatively high speed, the continuous operation of the grinding disc will cause its temperature to rise, accelerating the wear of the grinding disc and other components. Alternatively, if hard materials or foreign objects enter between the moving and stationary grinding discs, it will cause the grinding disc to crack. Therefore, how to improve the durability of the grinding disc has become the technical problem to be solved in this application. Utility Model Content

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0030] The following is for reference. Figure 1 Describes a colloid mill assembly 100 according to an embodiment of this application.
[0031] According to an embodiment of this application, a colloid mill assembly 100 includes a main housing 1, a controller 4, a feed bin 5, a feeder 6, and a linkage device. The main housing 1 has an abrasive chamber 11. The main housing 1 is provided with an inlet 12 and an outlet 13 communicating with the abrasive chamber 11. The abrasive chamber 11 contains a coaxial moving grinding disc 2 and a stationary grinding disc 3. The main housing 1 is positioned to control the starting and closing of the moving grinding disc 2. The feed bin 5 is located at the top of the main housing 1 and has an internal feed chamber 51. The bottom of the feed bin 5 has a feed outlet 52 communicating with the inlet 12. The feed outlet 52 is positioned and used to control its opening and closing. The linkage device links the feeder 6 with the controller 4. The linkage device drives the feeder 6 to open when the moving grinding disc 2 starts, or to close when the moving grinding disc 2 closes.
[0032] In related technologies, colloid mills are driven by an electric motor to rotate a moving grinding disc 2 and a matching stationary grinding disc 3 at high speed. The moving grinding disc 2 rotates at high speed while the stationary grinding disc 3 remains stationary. When the material passes through the gap between the moving and stationary grinding discs 3, it is subjected to strong shearing force, friction, high-speed vortex and other physical actions, which effectively deagglomerates and disperses the material, achieving the effect of fully dissociating the material to a suitable particle size. However, when the colloid mill operates at a relatively high speed, the continuous operation of the grinding disc will cause its temperature to rise, accelerating the wear of the grinding disc and other components. Alternatively, if hard materials or foreign objects enter between the moving and stationary grinding discs 3, it may cause the grinding disc to break. At this time, the feeding device of the colloid mill assembly 100 continuously feeds the material, which can easily cause the material to accumulate or be wasted.
[0033] Understandably, in the colloid mill assembly 100, the controller 4 controls the start and stop of the moving grinding disc 2, and the linkage device links the feeder 6 with the controller 4, so that the feeder 6 opens when the moving grinding disc 2 starts and closes when the moving grinding disc 2 stops. The linkage mechanism ensures the synchronization of material supply and grinding disc operation. During normal operation, when the moving grinding disc 2 starts and the feeder 6 opens, the material enters the grinding chamber 11 from the feed chamber 51 of the feed bin 5 through the feed inlet 52 and the feed outlet 12. The moving grinding disc 2 and the stationary grinding disc 3 begin to rotate relative to each other to process the material. Since the moving grinding disc 2 and the stationary grinding disc 3 are coaxially arranged, they can achieve a better grinding effect. At the same time, the linkage device can prevent the moving grinding disc 2 from running idle. When the moving grinding disc 2 rotates at high speed, there is no material between the grinding discs to provide a certain buffer and lubrication. The surfaces of the moving grinding disc 2 and the stationary grinding disc 3 directly contact and rub against each other, which will accelerate the wear of the grinding discs. However, through the linkage device, the moving grinding disc 2 only starts to operate when material enters the grinding chamber 11, which reduces the time of idle rotation of the grinding discs and reduces the wear caused by idle rotation, thereby improving the durability of the grinding discs.
[0034] Specifically, under abnormal operating conditions, when the colloid mill operates at a relatively high speed, the continuous operation of the grinding disc will cause its temperature to rise, accelerating the wear of the grinding disc and other components. Since the feeder 6 is linked to the moving grinding disc 2, when the grinding disc temperature is too high, the controller 4 can control the moving grinding disc 2 to shut down, and the feeder 6 will also shut down at the same time. At this time, the material stops entering the grinding chamber 11, and the moving grinding disc 2 no longer processes the material, avoiding further temperature increases due to continuous operation, reducing the adverse effects of high temperature on the grinding disc material properties, reducing the risk of high temperature-accelerated wear, and thus improving the durability of the grinding disc. Similarly, when hard materials or foreign objects enter between the moving and stationary grinding discs 3, it can cause the grinding disc to crack. In this case, if the feeding device continues to feed, it can easily cause material accumulation or further aggravate the damage to the grinding disc. By using the linkage device, once the moving grinding disc 2 stops operating due to foreign objects or other reasons, the controller 4 controls the moving grinding disc 2 to shut down, and at the same time the feeder 6 shuts down, the material stops entering. This avoids the problem from worsening when the grinding disc is already damaged, prevents additional extrusion damage to the grinding disc due to material accumulation, and reduces the possibility of the grinding disc continuing to come into contact with foreign objects or hard materials, thus protecting the grinding disc and improving its durability.
[0035] In short, through the linkage between the feeder 6 and the moving grinding disc 2, under abnormal temperature and foreign object conditions, the moving grinding disc 2 stops due to the abnormal conditions, and the linkage device activates the feeder 6 to stop feeding. This prevents more material from entering and worsening the problem when the grinding disc is already damaged, thus protecting the grinding disc, improving its durability, effectively reducing the adverse effects on the grinding disc, reducing the risk of wear and damage, and achieving the beneficial effect of improving the durability of the grinding disc.
[0036] According to some embodiments of this application, the colloid mill assembly 100 further includes a temperature sensor 7, which is disposed in the abrasive chamber 11. The detection end of the temperature sensor 7 extends to the stationary grinding disc 3 and is used to detect the temperature of the stationary grinding disc 3. The temperature sensor 7 is connected to a controller 4. The controller 4 controls the moving grinding disc 2 to shut down after the temperature detected by the temperature sensor 7 exceeds a preset temperature.
[0037] Temperature sensor 7 is installed inside abrasive chamber 11, with its detection end extending to stationary grinding disc 3, ensuring that the temperature of stationary grinding disc 3 is monitored. As a component in the material handling process, stationary grinding disc 3 generates a large amount of frictional heat by rotating relative to moving grinding disc 2, and its surface temperature can most directly reflect the heating state of the grinding disc during operation.
[0038] During operation, the thermal element inside the temperature sensor 7 changes its electrical parameters as the temperature of the stationary grinding disc 3 changes. After receiving the temperature data from the temperature sensor 7, the controller 4 compares and analyzes it with the preset temperature in real time. When the temperature detected by the temperature sensor 7 exceeds the preset temperature, the controller 4 immediately initiates the command to shut down the moving grinding disc 2. This command is quickly transmitted to the drive motor control system of the moving grinding disc 2 through the control circuit, cutting off the motor power supply or reducing the motor speed, so that the moving grinding disc 2 stops rotating. At the same time, since the feeder 6 is connected to the controller 4 through a linkage device, the controller 4 will simultaneously control the feeder 6 to close when issuing the command to shut down the moving grinding disc 2, cutting off the channel for material to enter the grinding chamber 11.
[0039] Understandably, grinding discs are typically made of specific metal alloys or hard-coated materials. Under high temperatures, the physical and chemical properties of these materials change. High temperatures reduce the hardness and toughness of metal materials, accelerating wear on the grinding disc surface. For surface coatings, high temperatures may weaken the adhesion between the coating and the substrate, leading to peeling. By promptly shutting off the moving grinding disc 2 and stopping the feed, the grinding disc is prevented from operating continuously at high temperatures, maintaining the original properties of the grinding disc material, thereby reducing the wear rate and improving durability.
[0040] The colloid mill assembly 100 according to some embodiments of this application further includes a drive device 8, which is disposed at the bottom of the main housing 1. An output shaft 81 is disposed at the top of the drive device 8, and the output shaft 81 is connected to the moving grinding disc 2. The drive device 8 is electrically connected to a controller 4, which is adapted to control the drive device 8 to stop after the current of the drive device 8 exceeds a preset value.
[0041] As the power source for the moving grinding disc 2, the operating current of the drive device 8 is directly related to the load size. When foreign objects or hard particles enter between the grinding discs, the rotational resistance of the moving grinding disc 2 will increase sharply. According to the load characteristics of the motor, the drive device 8 needs to output a larger torque to maintain rotation, resulting in a significant increase in the operating current. In addition, when the material concentration is too high or the feed rate is too large, the accumulation of material between the grinding discs will also increase the rotational resistance, causing an abnormal increase in current.
[0042] The preset current threshold in controller 4 is a safe current value set based on factors such as the rated power of drive device 8, the normal operating load of the grinding disc, and the characteristics of the material. When the current of drive device 8 exceeds the preset value, controller 4 immediately issues a shutdown command. This command is quickly transmitted to the power control module of drive device 8 via an electrical signal, cutting off the drive power supply in a short time and causing the moving grinding disc 2 to stop rotating rapidly. Timely shutdown through current monitoring effectively prevents the grinding disc from being subjected to continuous and severe impacts due to foreign object blockage, which could cause cracks or breakage. Under material overload conditions, rapid shutdown can prevent the grinding disc from experiencing accelerated surface wear or a sharp increase in temperature due to prolonged high-load operation. This protection mechanism significantly reduces the risk of damage to the grinding disc under abnormal operating conditions and extends the service life of the grinding disc.
[0043] According to some embodiments of the present application, in the colloid mill assembly 100, the moving grinding disc 2 is disposed at the bottom of the stationary grinding disc 3, and a feeding channel 31 is provided between the stationary grinding disc 3 and the feed inlet 12. The feeding channel 31 passes through the stationary grinding disc 3 to transport the material between the moving grinding disc 2 and the stationary grinding disc 3.
[0044] In the colloid mill assembly 100, the moving grinding disc 2 is located at the bottom of the stationary grinding disc 3, and a through feeding channel 31 is provided between the stationary grinding disc 3 and the feed inlet 12. This allows the material to be directly and efficiently transported to the working area between the moving grinding disc 2 and the stationary grinding disc 3 after entering from the feed inlet 12, with the help of gravity and the guiding effect of the feeding channel 31. This avoids unnecessary accumulation and blockage of the material during the conveying process due to the detour and turning of the path, and the material flows more smoothly in the feeding channel 31.
[0045] According to some embodiments of the present application, the colloid mill assembly 100 has a cooling chamber 14 formed inside the main housing 1, which is spaced apart from the abrasive chamber 11. The cooling chamber 14 is used to store the cooling medium and is located on the outer periphery of the feeding channel 31 and connected to the stationary grinding disc 3.
[0046] The cooling chamber 14 surrounds the outer periphery of the feeding channel 31 and is tightly connected to the stationary grinding disc 3, forming a heat exchange structure. When the grinding disc generates heat due to high-speed rotation, the heat from the stationary grinding disc 3 is rapidly transferred to the wall of the cooling chamber 14 connected to it through heat conduction. The cooling medium stored in the cooling chamber 14 continuously absorbs heat and carries it away. The close contact between the cooling chamber 14 and the stationary grinding disc 3 significantly reduces the thermal resistance and effectively suppresses the rise in grinding disc temperature. Because the cooling system effectively suppresses the wear and thermal damage of the grinding disc, the replacement cycle of the grinding disc is reduced, thus reducing maintenance costs.
[0047] According to some embodiments of the present application, the colloid mill assembly 100 includes a main housing 1, an outer cylinder 15 and a partition 16. The top of the outer cylinder 15 is provided with a feed inlet 12 and the side of the outer cylinder 15 is provided with a discharge outlet 13. The partition 16 is disposed inside the outer cylinder 15 and divides the interior of the outer cylinder 15 into a cooling chamber 14 and an abrasive chamber 11 that are spaced apart from each other in the height direction. The partition 16 is fitted to the stationary grinding disc 3.
[0048] The main housing 1 consists of an outer cylinder 15 and a partition 16. The partition 16 divides the interior of the outer cylinder 15 into a cooling chamber 14 and an abrasive chamber 11. The partition 16 is fitted tightly to the stationary grinding disc 3, allowing the heat generated by the stationary grinding disc 3 to be quickly transferred to the cooling chamber 14 through the partition 16. Because the partition 16 is tightly fitted to the stationary grinding disc 3, the thermal resistance during heat transfer is reduced. According to the principle of heat conduction, heat is transferred from the high-temperature abrasive chamber 11 to the low-temperature cooling chamber 14 through the partition 16. The cooling medium in the cooling chamber 14 can quickly absorb heat, achieving efficient heat exchange. When the moving grinding disc 2 rotates at high speed and the stationary grinding disc 3 generates heat through friction with the material, the heat can be quickly conducted to the partition 16 and then carried away by the cooling medium in the cooling chamber 14, effectively reducing the temperature of the grinding disc and ensuring that the grinding disc operates within a suitable temperature range, avoiding performance degradation and accelerated wear caused by excessively high grinding disc temperature.
[0049] According to some embodiments of the present application, the colloid mill assembly 100 has a cover plate 17 that is closable on the top of the outer cylinder 15, and the cover plate 17 can selectively open the cooling chamber 14.
[0050] The closable cover 17 on the top of the outer cylinder 15 allows selective opening of the cooling chamber 14. When the cooling medium needs to be replenished or replaced, opening the cover 17 allows for operation. During long-term operation of the colloid mill, the cooling medium may decrease due to high-temperature evaporation. In this case, opening the cover 17 to add cooling medium ensures the normal operation of the cooling system. For situations where the cooling medium needs to be replaced periodically to maintain the cooling effect, in order to prevent the coolant from deteriorating and affecting the cooling performance, opening the cover 17 to replace the coolant can maintain the efficient heat dissipation capacity of the cooling chamber 14, thereby stabilizing the working temperature of the grinding disc, reducing wear on the grinding disc caused by high temperature, and extending the service life of the grinding disc. As the colloid mill operates, impurities and dirt may accumulate inside the cooling chamber 14, affecting the cooling effect. Opening the cover 17 allows for cleaning of the cooling chamber 14, removing these impurities, ensuring the cleanliness of the cooling medium, improving the heat dissipation efficiency of the cooling chamber 14, ensuring that the grinding disc is always in a good working temperature environment, and improving the overall performance of the colloid mill assembly 100.
[0051] According to some embodiments of the present application, the colloid mill assembly 100 includes a controller 4 comprising a control panel 41 and an overload relay 42. The control panel 41 is provided with a first control switch and a second control switch. The first control switch is electrically connected to the drive device 8, and the second control switch is electrically connected to the feeder 6. The first control switch and the second control switch are linked together. The overload relay 42 is connected between the first control switch and the drive device 8.
[0052] The first and second control switches on control panel 41 are linked to ensure that the drive unit 8 and feeder 6 start and stop synchronously. When starting the colloid mill, operating the first control switch simultaneously starts the drive unit 8 and feeder 6, ensuring that material supply and grinding disc rotation begin synchronously. This prevents situations where feeder 6 runs alone or drive unit 8 idles due to operator negligence. If drive unit 8 fails to start while feeder 6 runs alone, material will accumulate in grinding chamber 11, causing blockage; if drive unit 8 idles, it will accelerate grinding disc wear. Linkage control effectively prevents these problems, improving equipment safety and reliability. In case of emergency shutdown, the first control switch must be turned off to simultaneously stop drive unit 8 and feeder 6. This prevents material from continuing to enter grinding chamber 11 if feeder 6 is not stopped in time, thus aggravating equipment damage. Linkage control ensures that feeder 6 stops synchronously the moment drive unit 8 stops, reducing the risk of material accumulation and equipment damage.
[0053] Overload relay 42 is connected between the first control switch and the drive device 8, and monitors the operating current of the drive device 8 in real time. When the current of the drive device 8 exceeds the preset value due to excessive load, the overload relay 42 will automatically cut off the circuit and stop the operation of the drive device 8, preventing the drive device 8 from burning out due to overload. It also protects the grinding disc from damage caused by excessive torque. When the overload relay 42 triggers power-off, not only does the drive device 8 stop running, but the feeder 6 will also stop working synchronously due to the linkage between the first and second control switches. This ensures that the material supply stops immediately when the equipment is overloaded, preventing material from continuing to enter the grinding chamber 11 and increasing the burden on the equipment. It also prevents more high-viscosity materials from entering the grinding chamber 11, reducing the difficulty of restoring normal operation of the equipment and reducing maintenance costs and downtime.
[0054] According to some embodiments of the present application, in the colloid mill assembly 100, the temperature sensor 7 is electrically connected to the control panel 41 and controls the first control switch to disconnect after the temperature exceeds a preset temperature.
[0055] Temperature sensor 7 is installed at the stationary grinding disc 3, enabling it to sense real-time temperature changes on the disc surface and convert the temperature signal into an electrical signal, which is continuously transmitted to control panel 41. Control panel 41 has a preset safe temperature threshold. When the temperature data from temperature sensor 7 exceeds the preset temperature, control panel 41 reacts quickly, triggering the first control switch electrically connected to it to disconnect. After the first control switch disconnects, the power supply to drive device 8 is cut off, and the moving grinding disc 2 immediately stops rotating. Because the first and second control switches are linked, feeder 6 also stops feeding material synchronously, preventing material from continuing to enter the grinding chamber 11, forming a complete closed loop. The linkage between temperature sensor 7 and control panel 41 reduces equipment failure rate and improves the stability and reliability of equipment operation. Simultaneously, reduced equipment failures decrease maintenance frequency and downtime, improving equipment efficiency and significantly reducing maintenance costs.
[0056] According to some embodiments of the present application, the colloid mill assembly 100 controller 4 further includes a photoelectric alarm 9, which is electrically connected to the temperature sensor 7 and the overload relay 42, respectively.
[0057] Understandably, when abnormal signals from temperature sensor 7 and overload relay 42 are transmitted to photoelectric alarm 9, visually, the photoelectric alarm 9 will immediately trigger a bright, flashing warning light, quickly attracting the operator's attention in a noisy industrial environment. Auditorily, the alarm will emit a high-decibel, rapid, and easily identifiable buzzing sound, clearly distinguishable from normal equipment operation sounds, ensuring that operators can detect abnormalities immediately. When a temperature alarm sounds, if it is a temperature fault, timely repair can prevent the grinding disc from degrading in material performance and cracking due to thermal stress concentration. When an overload alarm occurs, it can be checked for material blockage, foreign objects entering the grinding disc gap, etc. After eliminating the abnormal operating conditions, the colloid mill assembly 100 can be restarted.
