Abstract
Description
Technical Field
[0001] This application relates to the field of centrifuge technology, and more particularly to a monitoring device. Background Technology
[0002] A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials. When a centrifuge is operating, ensure the top cover is properly closed to prevent parts or materials from being thrown out and causing injury to the operator. Also, monitor the centrifuge for noise levels; if any abnormal noise occurs, immediately slow down and stop the machine to troubleshoot the problem. Centrifuge operation requires monitoring. When a centrifuge is running under load, the vibration amplitude increases with the imbalance and rotational speed. If there is no vibration monitoring or the monitoring system is malfunctioning, excessive vibration may cause the drum to tear due to the large centrifugal force, resulting in a major equipment accident and posing a safety hazard to nearby personnel.

[0030] like Figure 1 and Figure 2 As shown, some embodiments of this application provide a monitoring device, which is mainly used for monitoring centrifuge 100, so as to realize real-time monitoring of centrifuge 100 during operation and ensure the safety and stability of centrifuge 100 during operation.
[0031] The monitoring device includes a control box 200, a detector 300, a vibration sensor 400, and at least one centrifuge 100.
[0032] It is understandable that the number of centrifuges 100 can be one, two, or more, depending on the specific circumstances.
[0033] The centrifuge 100 includes a body 110 and a cover 120. The body 110 has an opening located on one side of the body 110 along a first direction. The cover 120 is movably connected to the body 110 and covers the opening, thereby sealing the opening to ensure the safety of the centrifuge 100 during operation.
[0034] It should be noted that the connection method between the cover 120 and the body 110 includes at least one of threaded connection, bolt connection, snap-fit, magnetic connection, and hinge connection, which can be specifically set according to the actual situation.
[0035] It is understandable that by movably connecting the cover 120 and the body 110 so that the cover 120 can be opened or closed on the body 110, not only can the sealing quality of the cover 120 on the body 110 be guaranteed, but the ease of operation can also be improved.
[0036] In this embodiment, the first direction is the vertical direction.
[0037] The control box 200 is electrically connected to the centrifuge 100. It should be noted that the centrifuge 100 has a power distribution box 700, which provides power to the centrifuge 100 to ensure its stability during operation. In this embodiment, the control box 200 is electrically connected to the power distribution box 700 of the centrifuge 100. The control box 200 is used to monitor the centrifuge 100 and, when an abnormality occurs in the centrifuge 100, sends a shutdown signal to the power distribution box 700.
[0038] The detector 300 is located on the side of the centrifuge 100 near the cover 120. The detector 300 is used to detect the position of the cover 120. The detector 300 is electrically connected to the control box 200 so that the detected data is sent to the control box 200 by the detector 300 as a signal. The control box 200 receives the signal, identifies and judges the signal, and controls the start or stop of the centrifuge 100 according to the judgment result.
[0039] It should be noted that in this embodiment, the centrifuge 100 cannot start normally when the detector 300 detects that the cover 120 is not closed.
[0040] The detector 300 here detects the position of the cover 120, meaning that the detector 300 detects the position of the cover 120 relative to the body 110.
[0041] For example, when the detector 300 detects that the distance between the cover 120 and the body 110 is zero, that is, the cover 120 is closed relative to the body 110, the centrifuge 100 can be started via the control box 200. When the detector 300 detects that the distance between the cover 120 and the body 110 is greater than zero, that is, when there is a gap or the cover 120 is open, meaning the cover 120 is not completely closed, the centrifuge 100 cannot be started via the control box 200 to ensure the safety of the centrifuge 100 during use.
[0042] In addition, a vibration sensor 400 is installed on one side of the centrifuge 100 and electrically connected to the control box 200. The vibration sensor 400 can detect the vibration of the centrifuge 100 in real time and send the detected vibration data to the control box 200 via a signal. The control box 200 receives the vibration data, identifies and judges it, and controls the centrifuge 100 to start or stop based on the judgment result.
[0043] For example, in some embodiments, during the operation of the centrifuge 100, the vibration value of the centrifuge 100 is sent to the control box 200 in real time by the vibration sensor 400. The control box 200 compares the vibration values received in each preset time period. If the vibration values are the same three times in a row, the vibration sensor 400 is determined to be faulty. The control box 200 sends a stop command to the power distribution box 700 of the centrifuge 100 and controls the centrifuge 100 to stop running.
[0044] For example, in some other embodiments, during the operation of centrifuge 100, when vibration sensor 400 detects that the vibration value of centrifuge 100 exceeds a preset value for more than n seconds, it indicates that centrifuge 100 is vibrating abnormally. The control box 200 sends a stop command to the power distribution box 700 of centrifuge 100 and controls centrifuge 100 to stop running.
[0045] In addition, when the centrifuge 100 transitions from the running time to the free deceleration stage, if the vibration value exceeds the set value, the control box 200 will suspend monitoring of the centrifuge 100 to prevent false alarms. The control box 200 will resume monitoring of the centrifuge 100 when the drum in the centrifuge 100 comes to a stop.
[0046] In some embodiments, when the centrifuge 100 switches from the running state to the shut-off state, if the vibration value of the centrifuge 100 in the shutdown state is detected by the vibration sensor 400 as being greater than the preset shutdown vibration value, then the control box 200 sends a shutdown command to the power distribution box 700 of the centrifuge 100.
[0047] The monitoring device provided in this application connects the centrifuge 100 to the control box 200 to monitor the operating status and vibration status of the centrifuge 100 in real time through the control box 200, so as to ensure the stability of the centrifuge 100 during operation. The control box 200 can also monitor the abnormal operating status of the centrifuge 100 in real time to prevent the centrifuge 100 from operating abnormally or being prohibited from starting abnormally, thereby ensuring the safety of the centrifuge during operation or start-up.
[0048] The detector 300 can be any one of the following: limit switch, proximity switch, photoelectric switch, micro switch, reed switch, pressure sensing switch, infrared ranging module, or laser ranging module, and can be specifically set according to the actual situation.
[0049] In this embodiment, detector 300 is a limit switch.
[0050] like Figure 1As shown, in some embodiments of this application, the body 110 includes a shell 111 and a base 112. The connection method between the base 112 and the shell 111 includes any one of threaded connection, bolt connection, snap-fit, adhesive or integral molding, which can be specifically set according to the actual situation.
[0051] In this embodiment, the base 112 is disposed on one side of the outer casing 111 along the first direction, the cover 120 is disposed on the side of the outer casing 111 away from the base 112, and the vibration sensor 400 is disposed on one side of the base 112 to monitor the vibration of the centrifuge 100 in real time.
[0052] In some embodiments of this application, the distance between the vibration sensor 400 and the housing 111 is L, wherein the value of L is in the range of 50mm≤L≤300mm.
[0053] It is understandable that the value of L can be any of the following ranges: 50mm≤L≤300mm, 100mm≤L≤300mm, 150mm≤L≤300mm, 200mm≤L≤300mm, or 250mm≤L≤300mm, and can be set according to the actual situation.
[0054] The accuracy of vibration detection of centrifuge 100 by vibration sensor 400 is improved by adjusting the distance between vibration sensor 400 and housing 111.
[0055] like Figure 2 As shown, in some embodiments of this application, a reset button 500 is provided on one side of the controller 210.
[0056] The reset button 500 is used to reset the centrifuge 100 in case of a fault.
[0057] like Figure 2 As shown, in some embodiments of this application, the control box 200 includes a controller 210 and a touch screen 220, the touch screen 220 is electrically connected to the controller 210, and the power distribution box 700 of the centrifuge 100, the detector 300 and the vibration sensor 400 are respectively electrically connected to the controller 210.
[0058] In this embodiment, the touch screen 220 can display the status of the top cover, such as the top cover not closed or the top cover closed.
[0059] In addition, the touch screen 220 can also display whether the centrifuge 100 was opened after its last shutdown. It should be noted that if the centrifuge 100 runs a free stop once and the operator restarts the centrifuge 100, and the detector 300 does not detect any opening of the lid during the process, the touch screen 220 will display that the centrifuge 100 was not opened after its last shutdown. At this time, the centrifuge 100 cannot be started. If the centrifuge 100 needs to be restarted, the start button should be pressed and held for three seconds.
[0060] like Figure 2 As shown, in some embodiments of this application, the monitoring device further includes an alarm 1000, which is electrically connected to the controller 210 so that the controller 210 can control the alarm 1000 to start or stop.
[0061] In some embodiments, when the control box 200 issues a stop command, the control box 200 monitors in real time whether the centrifuge 100's operating signal has stopped. If the centrifuge 100's operating signal is not disconnected within 3 seconds, the control box 200 sends a control signal to the alarm 1000, and the alarm 1000 issues an audible and visual alarm.
[0062] Among them, the alarm 1000 can be at least one of the following: a buzzer, a voice alarm, and an alarm light, and can be specifically set according to the actual situation.
[0063] In this embodiment, the alarm 1000 is a buzzer, which is an electronic sound-generating device that produces sound signals through vibration. Buzzers have advantages such as simple structure, low power consumption, fast response speed, strong real-time performance, small size, easy integration, high reliability, long lifespan, and adjustable tone.
[0064] like Figure 2 As shown in some embodiments of this application, the monitoring device includes a signal light 600, which is connected to the controller 210. The signal light 600 is used to indicate that the control box 200 is working normally. When the control box 200 malfunctions, the signal light 600 is turned off, and the centrifuge 100 cannot be started.
[0065] like Figure 2 As shown, in some embodiments of this application, the monitoring device includes multiple centrifuges 100, which are spaced apart from each other, and the power distribution box 700 of each centrifuge 100 is electrically connected to the control box 200.
[0066] By setting up multiple centrifuges 100 and connecting the power distribution box 700 of each centrifuge 100 to the control box 200, the utilization rate of the control box 200 is improved and the detection efficiency is increased.
[0067] In this embodiment, the number of detectors 300, vibration sensors 400, and centrifuges 100 is equal. Each detector 300 and vibration sensor 400 is connected to one centrifuge 100, thereby connecting the detectors 300, vibration sensors 400, and centrifuges 100 in a one-to-one correspondence. Each centrifuge 100 can be monitored in real time through the control box 200. The control box 200 not only enables centralized control and management of multiple centrifuges 100, but also saves costs and space and optimizes energy efficiency.
[0068] like Figure 1 As shown, in some embodiments of this application, the base 112 is provided with a drive rod 800 on the side facing the cover 120. The connection method between the drive rod 800 and the base 112 includes any one of rotational connection, snap-fit, bolt connection, and threaded connection, which can be specifically set according to the actual situation.
[0069] In this embodiment, the end of the drive rod 800 away from the base 112 is provided with a connecting rod 900. The connecting rod 900 is rotatably connected to the drive rod 800. The end of the connecting rod 900 away from the drive rod 800 is connected to the cover 120 to rotatably connect the cover 120 and the drive rod 800, so as to open or close the cover 120 from the centrifuge 100.
[0070] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0071] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
