Description

Technical Field

[0001] This utility model relates to the fields of sewage treatment and tap water treatment, and in particular to a sludge scraper with an automatic tensioning device. Background Technology

[0002] Chain scrapers are key equipment in rectangular tanks such as perimeter-inlet / perimeter-outlet sedimentation tanks, horizontal-flow sedimentation tanks, grit chambers, and grease traps in wastewater treatment plants. They are mainly used for the continuous scraping and removal of sludge from the bottom of the tank and the removal of surface scum. A drive motor drives a sprocket that rotates two parallel chains in a circular motion. Scrapers on the chains push the sludge to a discharge pipe or collection tank, while simultaneously achieving sludge-water separation through a suction pipe and scraping away surface scum. However, during long-term operation, the chains are prone to loosening, sagging, or even breaking due to wear, thermal expansion and contraction, severely affecting the stability of the equipment.

[0003] Due to the complex composition of wastewater and uneven fluid distribution within the tank, the operating resistance on both sides of the scraper often differs. When the chain loosens, the tension on both sides becomes inconsistent, causing the scraper to move asynchronously and resulting in a tilting or misalignment phenomenon (the side with greater resistance lags behind, and the side with less resistance leads). Misalignment not only reduces scraping efficiency but can also exacerbate chain wear and even lead to chain detachment or breakage. Currently, chain tension and scraper misalignment adjustment mainly rely on manual adjustment, requiring operators with high levels of professional experience and continuous on-site observation. In actual operation and maintenance, timely response is difficult, resulting in lag and unreliability.

[0004] The existing technology, a non-metallic chain scraper chain tensioning device and its usage method (CN201711310880.2), although it has a scheme to achieve automatic tensioning by installing a torque sensor, relies on the torque threshold to judge the chain state, which has significant defects in practical application.

[0005] Because different sedimentation tanks vary significantly in size, wastewater composition, and operating resistance, long-term data collection is required to determine the torque threshold. This results in a lengthy equipment commissioning cycle, and during the data accumulation phase, the tension status cannot be effectively monitored. Faults can easily lead to inaccurate data, causing significant deviations in the calculated preset threshold and ultimately affecting the reliability of the threshold setting. Therefore, this method is not highly applicable in practice. Utility Model Content

[0006] To solve the aforementioned problems in the prior art, this utility model provides a sludge scraper with an automatic tensioning device.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A sludge scraper with an automatic tensioning device includes a drive unit, a traction chain, a scraper assembly, and an automatic tensioning device; two traction chains are arranged on two opposite sides in a sedimentation tank; each traction chain is simultaneously engaged with a bearing, and the drive unit is connected to the traction chain for driving the traction chain to rotate cyclically.

[0009] The automatic tensioning device includes: a tensioning housing, a tensioning motor, a tension sensor, and steel wire ropes; the tensioning housing is located above two opposite sides of the sedimentation tank, and the two steel wire ropes are respectively connected to the tension sensors and traction chains above two opposite sides of the sedimentation tank. The upper end of each steel wire rope is connected to the tensioning motor through the tension sensor, and the lower end of the steel wire rope is connected to the bearing of the traction chain.

[0010] Preferably, each of the traction chains simultaneously engages with the sprocket drive.

[0011] Furthermore, the tension sensor includes a tensioning part and a detection part. The tensioning motor and the wire rope are respectively connected to the tensioning parts at both ends of the tension sensor, and the detection part is electrically connected to a display instrument for measuring the force value.

[0012] Furthermore, the tensioning motor is connected to a tension sensor via a lead screw, the tension sensor is connected to the upper end of the wire rope, and the wire rope is wound around a pulley and connected to the bearing of the traction chain.

[0013] Furthermore, the bearing connected to the traction chain includes a drive shaft, a driven shaft, and a tension shaft; the drive device is connected to the drive shaft, and each of the traction chains is simultaneously engaged with the drive shaft, driven shaft, and tension shaft.

[0014] Furthermore, the tensioning shaft is slidably disposed within the tensioning slide rail, and the tensioning motor is connected to the tensioning shaft via a steel wire rope.

[0015] Furthermore, the tensioning shell has multiple detection holes in the vertical direction for detecting the position of the wire rope, and the tension sensor is connected to a sensing block; the detection holes are equipped with multiple synchronous detection devices for sensing the sensing block.

[0016] Preferably, the synchronous detection device includes a proximity switch detection device, and an elongated hole is provided on the side of the tensioning housing. The proximity switch detection device is installed at the elongated hole on the side of the tensioning housing. Further, the tensioning motor is located on the top of the tensioning housing and is connected to a worm gear jack. The worm gear jack drives the displacement of the wire rope, along with the tension sensor and the sensing block.

[0017] Furthermore, the tensioning motor and the top of the tensioning housing are provided with a rain cover.

[0018] Furthermore, the drive device includes a drive motor, a drive reducer, and a torque sensor for real-time monitoring of the equipment's operating resistance. The drive motor is connected to the drive reducer via the torque sensor, and the drive reducer is connected to the traction chain via a drive chain.

[0019] Preferably, the torque sensor is electrically connected to the tensioning motor to prevent the scraper chain from being over-tensioned.

[0020] Furthermore, the tensioning outer shell is also provided with an observation hole for observing the internal tension sensor and changes in the wire rope.

[0021] Preferably, the tensioning slide rail is provided with a front limit block and a rear limit block for travel limiting, so that the tensioning shaft is pressed against by the front limit block or the rear limit block when it moves to the travel limit position.

[0022] Priority is that the automatic tensioning device also has a limit sensor, which serves as a protection mechanism.

[0023] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0024] ① By setting up a tension sensor to monitor the tension of the wire rope (i.e., chain) in real time, the tensioning motor automatically starts or stops according to the feedback signal of the tension sensor, and precisely adjusts the winding and unwinding of the wire rope, thereby realizing closed-loop automatic control of the tension of the traction chain, ensuring that the chain is always in the best tension state without frequent manual intervention.

[0025] ② Independent automatic tensioning devices (including their respective tensioning motors, tension sensors, and wire ropes) are installed on both opposite sides of the sedimentation tank. When the torque sensor monitors the running resistance of the drive device, if the running resistance is too high (possibly due to the chain being too tight or foreign objects blocking it), the tensioning motor can automatically adjust the tension or issue an alarm, effectively preventing equipment damage caused by excessive chain tension. This allows for independent or coordinated adjustment of the tension of the chains on both sides, ensuring that the two traction chains are subjected to balanced force and preventing the equipment from deviating from its intended path.

[0026] ③ A worm gear jack is used to convert the rotational motion of the motor into linear motion to pull the wire rope through a lead screw; these mechanisms usually have self-locking characteristics, can stably maintain the tensioned position, and have high transmission efficiency and more precise control.

[0027] ④ The tension sensor is connected to the display instrument to provide intuitive tension values, making it convenient for operators to monitor the chain status in real time.

[0028] ⑤ The tensioning housing is equipped with observation holes and detection holes for visual inspection of the internal wire rope and sensor condition. The detection holes and synchronous detection device (sensing block) provide additional, potentially more accurate means of position or condition monitoring, facilitating fault diagnosis and preventive maintenance.

[0043] Example 1

[0044] like Figures 1-9 As shown, this embodiment discloses a sludge scraper with an automatic tensioning device, including a drive device 1, a traction chain 2, a scraper assembly 3, and an automatic tensioning device 4; the two traction chains 2 are arranged on two opposite sides in the sedimentation tank; each traction chain 2 is simultaneously engaged with a bearing, and the drive device 1 is connected to the traction chain 2 for driving the traction chain 2 to rotate cyclically.

[0045] The automatic tensioning device 4 includes: a tensioning housing 5, a tensioning motor 6, a tension sensor 7, and steel wire ropes 8; the tensioning housing 5 is located above two opposite sides of the sedimentation tank, and the two steel wire ropes 8 are respectively connected to the tension sensor 7 and the traction chain 2 above two opposite sides of the sedimentation tank. The upper end of each steel wire rope 8 is connected to the tensioning motor 6 through the tension sensor 7, and the lower end of the steel wire rope 8 is connected to the bearing of the traction chain 2.

[0046] The tension sensor 7 includes a tensioning part and a detection part. The tension motor 6 and the wire rope 8 are respectively connected to the two ends of the tensioning part of the tension sensor 7. The detection part is electrically connected to the display instrument for measuring the force value.

[0047] The bearing connected to the traction chain 2 includes a drive shaft 9, a driven shaft 10, and a tension shaft 11; the drive device 1 is connected to the drive shaft 9 for transmission, and each of the traction chains 2 is simultaneously engaged with the drive shaft 9, the driven shaft 10, and the tension shaft 11.

[0048] The tensioning shaft 11 is slidably mounted inside the tensioning slide rail 12, and the tensioning motor 6 is connected to the tensioning shaft 11 via a steel wire rope 8.

[0049] There are two traction chains 2, which are arranged on the left and right sides of the sedimentation tank respectively. Each traction chain 2 is simultaneously engaged with the drive shaft 9, driven shaft 10 and tension shaft 11, and they are connected end to end.

[0050] The drive unit 1 is used to provide driving force for the traction chain 2. It includes a drive motor and a drive reducer, and is sequentially connected to the drive chain and multiple scraper assemblies 3 arranged on the drive chain. The drive motor of the drive unit 1 outputs power, which is reduced by the drive reducer and drives the drive shaft 9 to rotate through the drive chain. The drive shaft 9 meshes with two traction chains 2 through sprockets. The traction chains 2 rotate cyclically around the longitudinal section of the sedimentation tank along its length (meshing with the drive shaft 9, driven shaft 10 and tension shaft 11).

[0051] Multiple scraper assemblies 3 are evenly arranged at certain intervals on the traction chain 2. The scraper assemblies 3 are driven to move by the traction chain 2. The scraper assemblies 3 located at the bottom of the pool scrape the sludge at the bottom of the pool and scrape the sludge towards the sludge collection trough, while the scraper assemblies 3 located at the surface of the pool scrape the scum on the surface of the pool, thus achieving bidirectional cleaning.

[0052] The automatic tensioning device 4 is used to detect the tensioning movement of the traction chain 2. Under normal operating conditions, both ends of the traction chain 2 are always taut and rotate cyclically, meaning the traction chain 2 is parallel to the width of the tank. After the equipment has been running for a long time, the two traction chains 2 may wear and loosen, or even sag and break (since wear occurs slowly, the wear of the two traction chains 2 is basically the same under normal operating conditions). At this time, the traction chain 2 cannot be tensioned. Furthermore, after sewage enters the sedimentation tank, the settled sludge in different parts of the water body is usually uneven, and the sewage body is not in an absolutely uniform state. In addition, the installation error of the equipment itself will also cause the resistance on both sides of the equipment to be inconsistent. Therefore, in most cases, the running resistance experienced by the left and right ends of the scraper is often different. At this time, the scraper assembly 3 is easily pulled by the untensioned chain and tends to exhibit a movement posture with one end in front and the other end behind, that is, the scraper deviates. The automatic tensioning device 4 detects whether the two traction chains 2 are tight or loose, and whether the two ends of the scraper assembly 3 are synchronized, by detecting the array of tension sensors 7 on both sides of the sedimentation tank.

[0053] See Figure 6Inside the tensioning housing 5 at the top of both sides of the sedimentation tank, a travel limit detection module is also provided. This module includes: a limit detection device 14 for sensing the position of the end of the traction chain 2, which includes two position sensors set at different positions; a sensing block 13 is connected to the tension sensor 7 connected to the end of the traction chain 2. The two position sensors are respectively set to the upper and lower limit positions of the vertical movement of the sensing block 13 inside the tensioning housing 5. When the sensing block 13 moves with the end of the traction chain 2 to trigger either position sensor, it indicates that the slide rail travel has been exhausted (reaching the upper or lower limit), and an alarm is triggered to prevent the equipment from being damaged due to overtravel.

[0054] The synchronous detection device 14 includes a position sensor that uses contact sensing. Specifically, it may include a lever and a sensor switch. The two levers are respectively located on the outside of the tension sensor 7. Whenever the tension sensor 7 passes by, the tension sensor 7 will move the levers on both sides, thereby triggering the sensor switch and generating a sensing signal.

[0055] The synchronous detection device 14 can also use non-contact sensing, such as electromagnetic induction switch or photoelectric switch. When the tension sensor 7 passes by, the induction switch can sense the position information of the sensing block 13 and generate an induction signal.

[0056] Specifically, if the staff cannot detect the tension value of the tension sensor 7 of the automatic tensioning device 4 or detects that the tension value is too low, the traction chain 2 may have fallen off. In this case, the staff needs to stop the machine and reinstall it.

[0057] Specifically, when the tension of the wire rope 8 is insufficient, the tensioning motor 6 starts (tightening the wire rope 8 through the lead screw or worm gear lift 15) to increase the chain tension; when the tension is too high, the tensioning motor 6 reverses to release the wire rope 8.

[0058] Specifically, the torque sensor of the drive unit monitors the operating resistance in real time: when the sludge thickens and the resistance increases, the chain tension is automatically increased to prevent slippage; when the chain is detected to have continuous abnormal tension, the system alarm is triggered.

[0059] When the tension demand increases, the tensioning shaft 11 slides along the slide rail 12 away from the chain, increasing the chain wrap angle; when the tension demand decreases, the tensioning shaft 11 slides along the slide rail 12 towards the chain, releasing the chain slack.

[0060] This solution reduces tension error and achieves relative dynamic balance by monitoring data from the tension sensor 7, the tensioning motor 6, and displacement monitoring feedback. It solves the problems of incomplete sludge scraping, skipped teeth, and chain breakage caused by chain slack in traditional equipment, significantly improving sewage treatment efficiency and equipment reliability. It is suitable for high-load, continuous operation industrial scenarios.

[0061] Specifically, the tensioning housing 5 is equipped with observation holes and detection holes for visually inspecting the condition of the internal wire rope and sensors. This equipment can increase automatic tensioning while also having the function of detecting chain breakage or detachment, effectively preventing further damage to the equipment.

[0062] Example 2

[0063] like Figures 1-9 As shown, this embodiment discloses a sludge scraper with an automatic tensioning device. As one embodiment, the tensioning motor 6 is disposed on the top of the tensioning housing 5 and is connected to the worm gear lift 15. The worm gear lift 15 drives the steel wire rope 8 to move together with the tension sensor 7 and the sensing block 13. The top of the tensioning motor 6 and the tensioning housing 5 is provided with a rain cover.

[0064] The drive unit 1 includes a drive motor, a drive reducer, and a torque sensor for real-time monitoring of the equipment's operating resistance. The drive motor is connected to the drive reducer via the torque sensor, and the drive reducer is connected to the traction chain 2 via a drive chain.

[0065] When the drive unit 1 is started, the drive motor outputs power, and then the load is monitored by the torque sensor, the drive reducer is reduced in speed and increased in torque, and finally the drive chain drives the drive shaft 9 to rotate. The drive shaft 9 drives two traction chains 2 to rotate in a cycle, and the chains simultaneously mesh with the drive shaft 9, the driven shaft 10 and the tensioning shaft 11.

[0066] Specifically, the lower end of the wire rope 8 is connected to the tensioning shaft 11, and the upper end is connected to the screw 16 via the tension sensor 7. The screw 16 is connected to the worm gear lift 15, and the worm gear lift 15 is synchronously connected to the tensioning motor 6.

[0067] The tension sensor 7 detects the tension in real time. When the tension is insufficient, the tension motor 6 rotates forward, and then the worm gear lift 15 drives the screw 16 to press down, and finally tightens the wire rope 8 to increase the tension.

[0068] When the tension is too high, the tensioning motor 6 reverses, causing the worm gear jack 15 to drive the screw 16 to rise and release the wire rope 8. The worm gear mechanism has a natural self-locking feature, which can automatically maintain the tension and prevent it from being released in the event of an accidental power failure. Specifically, the worm gear transmission ratio can reach 1:50, achieving micron-level tension adjustment; the self-locking characteristic eliminates the energy consumption of the motor when maintaining the tension.

[0069] When operating in rainy weather, the rain cover covers the tension motor 6 and the top of the housing, and the worm gear jack 15 is sealed inside the tension housing 5. The rain cover prevents rainwater from entering the motor / sensor and avoids short circuits; the worm gear jack 15 is sealed inside the tension housing 5.

[0070] This embodiment solves the problem of chain tension loss in harsh outdoor working conditions by using a worm gear precision tensioning system, dual-end monitoring of the drive load, and a fully sealed protection design. It achieves high-precision adaptive sludge scraping and is particularly suitable for high-load scenarios such as large water treatment plants and sedimentation tanks.

[0071] Example 3

[0072] like Figures 1-9 As shown, this embodiment discloses a sludge scraper with an automatic tensioning device. As one embodiment, the tensioning housing 5 has multiple detection holes 501 in the vertical direction for detecting the position of the wire rope 8, and a sensing block 13 is connected to the tension sensor 7; multiple synchronous detection devices 14 for sensing the sensing block 13 are provided on the detection holes 501.

[0073] The tensioning housing 5 is also provided with an observation hole 502 for observing the changes in the internal tension sensor 7 and the wire rope 8.

[0074] During operation, the sensing block 13 moves up and down with the wire rope 8. The synchronous detection device 14 scans the position of the sensing block 13 through the detection hole 501, thereby feeding back the displacement. The displacement data is compared with the tension data of the tension sensor 7 to verify the effectiveness of the tensioning action (the displacement should increase synchronously when the tension increases), thereby effectively determining the sensor failure.

[0075] During shutdown and maintenance, the wear of the wire rope 8 and the status of the sensors can be checked through the observation hole 502. Internal components can be directly inspected visually (whether the wire rope 8 is rusted / broken, the connection status of the tension sensor 7, and whether the screw 16 is stuck), shortening maintenance time. If an abnormality is detected, the fault point can be located by combining historical displacement data from the synchronous detection device 14. This embodiment achieves comprehensive safety protection during the tensioning process through the integrated design of synchronous displacement monitoring and a visual observation window.

[0076] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
