Description

Technical Field

[0001] This invention relates to the field of centrifuge technology, specifically to a centrifuge material level detection device. Background Technology

[0002] A centrifuge is a mechanical device that uses centrifugal force generated by high-speed rotation to separate liquids from solid particles or liquids of different densities. Its core component is a high-speed rotating drum, which achieves efficient separation through centrifugal force field, hundreds of times faster than natural sedimentation.

[0003] In existing technologies, the feeding method in centrifuges is controlled by time. This feeding method cannot accurately control the amount of material inside the centrifuge, resulting in low detection accuracy. At the same time, the flow rate and fluidity of the existing feeders are constantly changing, often resulting in the centrifuge being either not fully filled or overfilled, thus leading to insufficient practicality. Therefore, there is a need for a device that can accurately feed according to changes in the amount of material inside the centrifuge to avoid low accuracy and insufficient practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a centrifuge level detection device to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: A centrifuge level detection device includes a workbench, a processing table on the workbench, a centrifuge on the processing table, a discharge port on the centrifuge, the discharge port being connected to the output end of a discharge machine via a conveying channel, the centrifuge including a support frame, a rotating drum containing discs at the center of the support frame, a spray nozzle on one side of the discs, a rotating body on the outside of the spray nozzle, a triggering component at the bottom of the rotating body, a driving component on the side of the triggering component, a control component on one side of the driving component, a nozzle switching component on the side of the control component, and a discharge component on one side of the switching component.

[0005] Preferably, the triggering component includes a connecting sleeve disposed at the bottom of the rotating body. The connecting sleeve is located below the bottom of the centrifuge and below the processing table. The bottom of the connecting sleeve is slidably engaged with the top of the processing table. The bottom of the centrifuge is provided with a fixed bracket. A rotating shaft is rotatably connected to the middle of the fixed bracket. A cam is eccentrically connected to the bottom of the rotating shaft. The cam is embedded in an annular groove in the middle of the connecting bracket. The center of the connecting bracket is concentrically positioned with the center of the centrifuge. Vertically positioned retaining pins are provided at the top of both ends of the connecting bracket. The top of the retaining pins is located in hollow grooves on both sides of the fixed bracket. Silicone sleeves are provided in the hollow grooves. The top of the retaining pins is located inside the silicone sleeves. The bottom of both ends of the connecting bracket is connected to the top of a gear ring sleeve. The outer side of the gear ring sleeve is rotatably engaged with the inner side of the bottom of the connecting sleeve.

[0006] Preferably, a drive bevel gear is rotatably connected to the workbench via a drive shaft. The drive shaft and the center of the gear ring are concentrically arranged. The tooth groove end of the drive bevel gear can mesh with the tooth groove end of the gear ring. A drive disk is provided at the bottom of the workbench. The center of the drive disk is connected to the bottom of the drive shaft. A first drive belt is sleeved on the outside of the drive disk. The other end of the first drive belt is sleeved on the outside of the drive disk. The center of the drive disk is rotatably connected to the bottom of the workbench.

[0007] Preferably, the driving assembly includes a driving roller located on the worktable, the center of the bottom of the driving roller being connected to the center of the driving disk, a continuous N-shaped groove being formed on the side end of the driving roller, a linkage gear being sleeved on the outer side of the top of the driving roller, a control gear being meshed on the side end of the linkage gear, the center of the control gear being rotatably connected to a support shaft via a one-way bearing, the bottom of the support shaft being rotatably connected to the processing table, a trigger gear being provided below the control gear, the center of the trigger gear being connected to the support shaft via a one-way bearing, a sliding toothed rod being meshed on the side end of the trigger gear, and the bottom of the sliding toothed rod being slidably engaged with the top of the processing table.

[0008] Preferably, the control component includes toothed blocks symmetrically arranged at both ends of the sliding toothed rod. The upper and lower sides of the toothed blocks are movably connected to the bases on the upper and lower sides of the sliding toothed rod through a first spring telescopic rod. The side of the sliding toothed rod away from the trigger gear is connected to the telescopic end of the second spring telescopic rod, and the bottom of the second spring telescopic rod is connected to the top of the processing table.

[0009] Preferably, the switching assembly includes a linkage rod disposed at the end of the sliding toothed rod away from the second spring telescopic rod. A pull rod is hinged to the end of the linkage rod, and the other end of the pull rod is hinged to the side end of the switching disc. The center of the switching disc is rotatably connected to the processing table via a switching shaft. The switching shaft is rotatably connected to the mating frame, which is disposed on the processing table. A second transmission belt is sleeved on the top outer side of the switching shaft, and the other side of the second transmission belt is sleeved on the outer side of the connecting shaft between the nozzle and the centrifuge. When the trigger gear rotates, it drives the sliding toothed rod to slide, causing the second spring telescopic rod to retract to its maximum extent. At this time, under the action of the pull rod, the output end of the nozzle rotates in the centrifuge to face the disc.

[0010] Preferably, the feeding assembly includes a sliding frame located at the side end of the drive roller. The bottom of the sliding frame is connected to the top of the worktable. A linkage block is slidably mounted on the sliding frame. The bottom of the linkage block is movably connected to the top of the worktable via a telescopic spring. The side of the linkage block facing the drive roller is movably connected to the end of a pressure rod via a compression spring. The pressure rod and the linkage block are slidably engaged. The end of the pressure rod away from the linkage block is embedded in and slidably engaged with an N-shaped groove. The other end of the linkage block is connected to a trigger rod. The other end of the trigger rod is located above the feeding switch of the feeding machine. The feeding switch is a push-button switch and is wedge-shaped on the side facing the trigger rod. The movement of the feeding switch can control the output of the feeding machine.

[0011] Preferably, the tooth diameter of the trigger gear is smaller than that of the linkage gear.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when the centrifuge is operating, the drum and rotating body inside the centrifuge rotate at high speed. After centrifugation, the material is guided by discs to disperse into the inner side of the rotating body for solid-liquid separation. Simultaneously, the nozzles work to rinse the material. When there is sufficient material inside the centrifuge, the overall weight of the rotating body is sufficient, resulting in relative stability between the rotating body and the support frame during high-speed rotation. At this time, the triggering and driving components do not interfere with each other. When the material inside the rotating body decreases, high-frequency vibration occurs between the rotating body and the support frame. The frequency of the vibration depends on the amount of material lost from the rotating body. When the loss is small, the output direction of the nozzles is switched so that they face the discs, thereby cleaning the material adhering to the surface of the discs. To avoid errors in judging the material inside the centrifuge, if the rotating body and the support frame become stable, the control component loses kinetic energy and the switching component drives the nozzle to reset. If the rotating body and the support frame continue to generate high-frequency vibration, the control component will drive the feeding component to work synchronously, so that the feeding machine feeds the centrifuge through the conveying channel until the rotating body and the support frame become stable, and then automatically stops. In this process, the feeding is controlled by time, which avoids the need to control the feeding. It can accurately control the amount of material inside the centrifuge, thereby improving the accuracy of detection. At the same time, it can control the feeding end in real time according to the working status of the centrifuge, thus avoiding the situation of insufficient or excessive feeding, and further improving the practicality of this device.

[0013] In this invention, by using components such as triggering components and driving components in combination, the lack of internal material can be identified according to the working status of the centrifuge, thereby improving the convenience of using the device.

[0014] In this invention, by using components such as control components and replacement components in combination, the material adhering to the surface of the disc can be cleaned, thereby avoiding errors in judging the material inside the centrifuge.

[0015] In this invention, by using components such as the feeding assembly in combination, the feeding is controlled by time, which can accurately control the amount of material inside the centrifuge, thereby improving the accuracy of detection. At the same time, the feeding end can be controlled in real time according to the working status of the centrifuge, thus avoiding the situation of insufficient or excessive material feeding, and further improving the practicality of this device.

[0016] In this invention, by setting a trigger gear with a small tooth diameter, the linkage gear can quickly move the sliding toothed rod to the designated position at the initial stage of transmission of the transmission disc, thereby enabling the nozzle to switch quickly and clean the disc surface, avoiding the long-term adhesion of materials on the disc surface, which would affect the normal operation of the centrifuge.

[0022] In this embodiment, as Figures 7 to 8 As shown, the control component 10 includes toothed blocks 101 symmetrically arranged at both ends of the sliding toothed rod 97.

[0023] In this embodiment, as Figures 9 to 10 As shown, the feeding assembly 12 includes a sliding frame 121 located at the side end of the drive roller 91.

The feeding switch 127 is a push-button switch and is wedge-shaped on the side facing the trigger rod 126. The movement of the feeding switch 127 can control the output of the feeding machine 6.

[0024] In this embodiment, as Figure 8 and Figure 9 As shown, the tooth diameter of the trigger gear 96 is smaller than that of the linkage gear 93.

[0025] The invention provides the following usage method and advantages: A centrifuge material level detection device operates as follows: like Figures 1 to 10As shown, when the centrifuge 3 has sufficient material inside, the overall weight of the rotating body 35 is sufficient, thus making the rotating body 35 relatively stable with respect to the support frame 31 during high-speed rotation. At this time, the gear ring sleeve 80 and the drive bevel gear 81 do not contact each other. When the material inside the rotating body 35 decreases, high-frequency vibration occurs between the rotating body 35 and the support frame 31. The frequency of vibration depends on the amount of material loss inside the rotating body 35. When the loss is small, the connecting sleeve 71 vibrates at high speed outside the drive bevel gear 81 through the gear ring sleeve 80. During the vibration, since the connecting bracket 75 is embedded in the annular groove 76 through the retaining shaft 77 and connected to the fixed bracket 72 through the cam 74 and the rotating shaft 73, the vibration direction of the gear ring sleeve 80 is limited, thereby enabling the vibration to be controlled. During the process, the drive bevel gear 81 is driven to rotate intermittently, thereby driving the drive disc 85 to rotate through the transmission disc 82 and the first transmission belt 84, causing the drive roller 91 to rotate synchronously. Since the linkage gear 93 and the control gear 94 mesh with each other, during the initial rotation, the control gear 94 and the support shaft 95 can be driven to rotate synchronously. Under the action of the trigger gear 96, the sliding toothed rod 97 is driven to work, which facilitates the switching of the output direction of the nozzle 34. After the nozzle 34 has cleaned the disc 32, the vibration continues, which triggers the feeding assembly 12 to feed the material according to the vibration frequency until the rotating body 35 and the support frame 31 tend to be stable. Thus, the missing material inside can be identified according to the working state of the centrifuge 3, thereby improving the convenience of using this device. When the sliding toothed rod 97 slides and the second spring telescopic rod 104 is compressed to its limit, the linkage rod 111 and the pull rod 112 work together to drive the changing disc 113 and the changing shaft 114 to rotate synchronously on the mating frame 115. The second transmission belt 116 drives the connecting shaft 117 and the nozzle 34 to rotate, so that the output end of the nozzle 34 faces the disc 32, thereby cleaning the material adhering to the surface of the disc 32, thus avoiding errors in judging the material inside the centrifuge 3. If the vibration between the rotating body 35 and the support frame 31 still exists at this time, the toothed block 101 and the first spring telescopic rod 102, in the process of the trigger gear 96 continuously cooperating with the sliding toothed rod 97, enable the sliding toothed rod 97 to maintain a stable displacement position until the rotating body 35 and the support frame 31 tend to be stable, thus improving the practicality of the device. When high-frequency vibration is continuously generated between the rotating body 35 and the support frame 31, the nozzle 34 switches its output direction under the action of the drive roller 91. At the same time, through the cooperation of the N-shaped chute 92 and the pressure rod 125, the linkage block 122 can be driven to slide downward along the sliding frame 121, and the telescopic spring 123 is compressed synchronously. Then, the trigger rod 126 is driven to move down until it contacts the discharge switch 127, so that the discharge machine 6 feeds material into the centrifuge 3 through the material conveying channel 5. The distance of the trigger rod 126 moving down is synchronously changed according to the vibration frequency, and the opening degree of the discharge switch 127 is controlled synchronously, thereby controlling the discharge amount. When the N-shaped chute 92 drives the pressure rod 125 to the bottom, the discharge speed is the maximum, and the telescopic spring 123 can quickly reset it to judge the material amount for the next round, thereby avoiding To prevent excessive material from being added, the centrifuge automatically stops once the rotating body 35 and the support frame 31 have stabilized. At this point, the drive assembly 9 stops working and, under the action of the telescopic spring 123, drives the linkage block 122 to reset. During the reset process, the drive roller 91 is reset synchronously, and through the one-way bearing, the control gear 94 can reset on the support shaft 95. After losing kinetic energy, the trigger gear 96 drives the sliding toothed rod 97 to reset under the action of the first spring telescopic rod 102, thereby resetting the nozzle 34. In this process, the feeding is controlled by time, and the amount of material inside the centrifuge 3 can be accurately controlled, thereby improving the accuracy of detection. At the same time, the feeding end can be controlled in real time according to the working status of the centrifuge 3, thus avoiding the situation of insufficient or excessive material feeding, further improving the practicality of this device. By setting a small-diameter trigger gear 96, the linkage gear 93 can quickly move the sliding toothed rod 97 to the designated position at the initial stage of transmission of the transmission disc 82, thereby enabling the nozzle 34 to switch quickly and clean the surface of the disc 32, avoiding the long-term adhesion of materials on the surface of the disc 32, which would affect the normal operation of the centrifuge 3.
