Description

Technical Field

[0001] This utility model relates to the field of mining machinery automation, and in particular to a peripheral drive thickener encoder synchronization control device. Background Technology

[0002] In industries such as mining, metallurgy, and chemicals, peripheral drive thickeners are key equipment for solid-liquid separation. Their transmission system typically consists of a motor driving gears to move along a track in a circular motion. Traditional control methods suffer from two major technical drawbacks. First, insufficient synchronization accuracy: when driven by multiple motors, mechanical wear and load differences can lead to asynchronous transmission, causing problems such as track wear and equipment vibration, thus shortening the equipment's lifespan. Second, lag in dynamic adjustment: existing encoder signal processing relies on manual experience-based threshold settings, which cannot respond in real time to fluctuations in operating conditions such as changes in mud concentration, affecting settling efficiency. To address these issues, we propose a peripheral drive thickener encoder synchronization control device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a peripheral drive condenser encoder synchronization control device.

[0004] The present invention solves its technical problem through the following technical solution: it includes a thickening tank, the inside of which is provided with a feeding mechanism, and the top of which is provided with a support mechanism. The support mechanism includes a mounting slider, which is slidably connected to the top of the thickening tank. A transmission frame is fixed to the top of the mounting slider, and a driving mechanism is provided on the inner wall of the transmission frame. The drive mechanism includes a motor mounting base, which is fixed to the inner wall of the transmission frame by bolts. A geared motor is fixed to the inner wall of the motor mounting base. A drive shaft is provided at the output end of the geared motor. A drive gear is fixed to the outside of the drive shaft. A gear ring is provided to the outside of the drive gear. The gear ring is fixedly connected to the thickening tank. A detection mechanism is provided to the outside of the transmission frame. The detection mechanism includes a mounting block, which is fixed to the bottom of the transmission frame by bolts. An absolute encoder is fixed to one side of the mounting block. A mounting bracket is fixed to the outside of the transmission frame by bolts. An incremental encoder is fixed to the inner wall of the mounting bracket. A connecting shaft is provided at the output end of the incremental encoder. A detection gear is fixed to the outside of the connecting shaft. The detection gear meshes with a gear ring. A controller is fixed to the top of the transmission frame.

[0005] As a further improvement of this utility model, a drain pipe is provided at the bottom of the concentration tank.

[0006] As a further embodiment of this utility model: the feeding mechanism includes an installation beam, which is fixed to the inner wall of the thickening tank, a flow stabilizing tank is fixed to the bottom of the installation beam, and a feed pipe is fixed to the outside of the flow stabilizing tank.

[0007] As a further embodiment of this utility model: a mounting shaft is fixed to the bottom of the transmission frame, a torque sensor is fixed to the outside of the mounting shaft, a mounting roller is fixed to the outside of the torque sensor, and a scraping mechanism is provided on the outside of the mounting roller.

[0008] As a further embodiment of this utility model: a support bushing is rotatably connected to the outer side of the mounting shaft, and the support bushing is fixedly connected to the transmission frame.

[0009] As a further embodiment of this utility model: the scraping mechanism includes a mounting rake frame, which is fixed to the outside of the mounting roller by bolts. Multiple mounting columns are fixed to the bottom of the mounting rake frame, and scraping plates are fixed to the bottom of each of the multiple mounting columns.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. Equipped with a drive mechanism and a detection mechanism, the transmission data of the drive shaft and drive gear is detected by an absolute encoder, which detects the rolling of the gear on the gear ring. The rotation data is transmitted to an incremental encoder through a connecting shaft. The incremental encoder detects the transmission data of the gear ring, and the controller monitors the pulse signals of the absolute encoder and incremental encoder in real time. When the difference exceeds 0.5°±, PID compensation is triggered, which can compensate for the wear of the drive gear and gear ring, improve the accuracy of synchronous control, extend the service life of the drive gear and gear ring, avoid problems such as track wear and equipment vibration, and ensure the efficiency of the settlement operation. 2. By setting up a support mechanism, the drive mechanism drives the transmission frame to rotate around the edge of the thickening tank. The torque sensor can detect the real-time torque of the mounting shaft, thereby detecting the torque of the mounting rake frame and controlling the output torque of the reduction motor. This can reduce the synchronous response time under sudden load conditions, respond in real time to fluctuations in working conditions such as changes in mud concentration, ensure the efficiency of the settling operation, and prevent torsional vibration of the mounting rake frame, thus achieving protective operation of the mounting rake frame.

The gear ring 440 is fixedly connected to the thickening tank 100. A detection mechanism is provided on the outside of the transmission frame 320. The detection mechanism includes a mounting block 510, an absolute encoder 520, and a mounting bracket 530. An incremental encoder 540 is fixed to the inner wall of the mounting bracket 530. A connecting shaft 541 is provided at the output end of the incremental encoder 540. A detection gear 550 is fixed to the outer side of the connecting shaft 541, and the detection gear 550 meshes with a gear ring 440. A controller 560 is fixed to the top of the transmission frame 320. A drive mechanism and a detection mechanism are provided. The absolute encoder 520 detects the transmission data between the drive shaft 421 and the drive gear 430. The detection gear 550 meshes with the gear ring. The gear ring 440 rolls on the gear and transmits its rotational data to the incremental encoder 540 via the connecting shaft 541. The incremental encoder 540 detects the transmission data of the gear ring 440, and the controller 560 monitors the pulse signals of the absolute encoder 520 and the incremental encoder 540 in real time. When the difference exceeds 0.5°±, PID compensation is triggered, which can compensate for the wear of the drive gear 430 and the gear ring 440, improve the accuracy of synchronous control, extend the service life of the drive gear 430 and the gear ring 440, avoid problems such as track wear and equipment vibration, and ensure the efficiency of the settling operation.

[0017] Specifically, the feeding mechanism includes a mounting beam 210, which is fixed to the inner wall of the thickener 100. A flow stabilizing tank 220 is fixed to the bottom of the mounting beam 210, and a feed pipe 230 is fixed to the outside of the flow stabilizing tank 220. With the feeding mechanism, the slurry enters the flow stabilizing tank 220 through the feed pipe 230, the flow stabilizing tank 220 stabilizes the slurry, and the slurry is injected into the thickener 100.

[0018] Specifically, a mounting shaft 330 is fixed to the bottom of the transmission frame 320, a torque sensor 340 is fixed to the outside of the mounting shaft 330, and a mounting roller 350 is fixed to the outside of the torque sensor 340. A scraping mechanism is provided on the outside of the mounting roller 350. With the support mechanism, the transmission frame 320 is driven to rotate around the edge of the thickening tank 100 by the drive mechanism. The torque sensor 340 can detect the real-time torque of the mounting shaft 330, thereby detecting the torque of the mounting rake frame 610 and controlling the output torque of the reduction motor 420. This reduces the synchronous response time under sudden load conditions, allows for real-time response to fluctuations in conditions such as changes in mud concentration, ensures the efficiency of the settling operation, and prevents torsional vibration of the mounting rake frame 610, thus achieving protective operation of the mounting rake frame 610.

[0019] Specifically, a support sleeve 331 is rotatably connected to the outer side of the mounting shaft 330, and the support sleeve 331 is fixedly connected to the transmission frame 320; by providing the support sleeve 331 to limit and support the rotation of the mounting shaft 330, the stability of the drive operation is ensured.

[0020] Specifically, the scraping mechanism includes a mounting rake frame 610, which is fixed to the outside of the mounting roller 350 by bolts. Multiple mounting columns 620 are fixed to the bottom of the mounting rake frame 610, and scraper plates 630 are fixed to the bottom of each of the mounting columns 620. By providing a scraping mechanism, the mounting rake frame 610 is rotated through the cooperation of the support mechanism and the drive mechanism, which in turn drives the scraper plates 630 to rotate, thereby assisting the settling of the slurry through the scraper plates 630.

[0021] Working Principle: During operation, the slurry enters the flow stabilizing tank 220 through the feed pipe 230. The flow stabilizing tank 220 stabilizes the flow of the slurry, which is then injected into the thickening tank 100. A reduction motor 420 drives the drive shaft 421 to rotate, which in turn drives the drive gear 430. The drive gear 430, in conjunction with the gear ring 440, drives the transmission frame 320 to rotate around the thickening tank 100, which in turn drives the mounting shaft 330 to rotate. The mounting shaft 330, via a torque sensor 340, drives the mounting roller 350 to rotate, which in turn drives the mounting rake frame 610 to rotate. The mounting column 620 drives the scraper 630 to rotate, assisting in the settling of the slurry. The torque sensor 340 can detect the real-time torque of the mounting shaft 330, thereby adjusting the mounting... The torque of the rake frame 610 is detected, and the output torque of the geared motor 420 is controlled to reduce the synchronous response time under sudden load conditions. During the process, the transmission data of the drive shaft 421 and the drive gear 430 is detected by the absolute encoder 520. The detection gear 550 rolls on the gear ring 440, and the rotation data is transmitted to the incremental encoder 540 through the connecting shaft 541. The transmission data of the gear ring 440 is detected by the incremental encoder 540, and the pulse signals of the absolute encoder 520 and the incremental encoder 540 are monitored in real time by the controller 560. When the difference exceeds 0.5°±, PID compensation is triggered, which can compensate for the wear of the drive gear 430 and the gear ring 440. The sediment of the slurry is discharged through the drain pipe 110.
