Description

Technical Field

[0001] This invention relates to the technical field of automated adjustment and correction during equipment use, specifically to a deviation warning and automatic adjustment device and its usage method for a non-metallic chain scraper for secondary sedimentation tanks, which detects deviation, automatically adjusts, and automatically tensions the scraper during use. Background Technology

[0002] As a new type of water treatment equipment, the non-metallic chain scraper is suitable for surface skimming and bottom sludge scraping in rectangular primary and secondary sedimentation tanks. It has a large number of scrapers, strong sludge scraping ability, and slow scraper movement speed, which causes less disturbance to the water flow and makes it less likely to cause floating scum to rise and deteriorate the quality of the effluent. At the same time, the scraper blades of the non-metallic chain scraper move in a continuous linear motion in the water without the need for switching, resulting in low energy consumption.

[0003] In industrial production, the drive sprocket fixed shaft of a non-metallic chain scraper, which is fixed to the pool wall, is prone to displacement due to its own weight and the tension of the chain. When the displacement angle is too large, the tension of the traction chain decreases, and the scraper is prone to friction with the pre-embedded track below the pool bottom, which increases the tension of the main shaft of the equipment and may eventually cause the machine to stop due to overload.

[0004] In industrial production, the traction chain of a chain scraper is made of non-metallic material. During long-term operation, especially when the sludge deposit at the bottom of the secondary sedimentation tank is thick, the chain load is large, which can easily cause chain fatigue or even tensile deformation. When the deformation accumulates significantly, the chain will slack, and the scraper will stop due to overload. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a deviation warning and automatic adjustment device for a chain scraper and its usage method.

[0006] According to an embodiment of the present invention, a deviation warning and automatic adjustment device for a chain scraper includes a main shaft and a transmission assembly horizontally rotatably disposed at both ends of the top of a sedimentation tank. The transmission assemblies are arranged in pairs and are respectively located on opposite inner walls of the sedimentation tank. The main shaft and the transmission assembly are connected by a chain drive. A scraper plate is connected between the two chains. The transmission assembly is provided with a detection unit for detecting vertical and horizontal tilt angles and a leveling component. A torque sensor is provided on the transmission assembly. The main shaft is rotatably mounted on a tensioning device, which is disposed on the sedimentation tank.

[0007] Preferably, the transmission assembly includes a base fixed to the inner wall of the sedimentation tank, a mounting shaft arranged vertically on the base and in a horizontal state, and a transmission sprocket rotatably mounted on the mounting shaft. The base is fixed by expansion bolts and is a hollow cylindrical structure. The end wall of the base is in contact with the inner wall of the sedimentation tank, and the detection unit is arranged inside the base.

[0008] Preferably, an angle rod is coaxially fixedly connected to the inner wall of the connection end between the base and the inner wall of the sedimentation tank. The detection unit includes a vertical angle detection group and a horizontal angle detection group. The vertical angle detection group includes a vertical angle detection strip hinged to one side of the angle rod and a semi-circular first arc strip fixedly disposed on one side of the angle rod. Both the vertical angle detection strip and the first arc strip are located on the side of the angle rod away from the main shaft. The horizontal angle detection group includes a horizontal angle detection strip hinged to the bottom end of the angle rod and a second arc strip fixedly disposed below the angle rod. Both the hinges of the vertical angle detection strip and the horizontal angle detection strip are provided with a reset torsion spring. Under the action of elastic force, the vertical angle detection strip and the horizontal angle detection strip are respectively in a state of abutting against the first arc strip and the second arc strip. The center of the first arc strip and the second arc strip are located at the fixed end of the angle rod. The first arc strip and the vertical angle detection strip, and the second arc strip and the horizontal angle detection strip are respectively two connected circuits, and each circuit is provided with a resistance meter. The first arc strip and the second arc strip are resistance strips.

[0009] Preferably, the first and second arc-shaped strips are fixed on the mounting base, which is an arc-shaped plate. The base plate, which is attached to the inner wall of the sedimentation tank, has an arc-shaped opening for accommodating the mounting base. The mounting base is directly connected to the inner wall of the sedimentation tank.

[0010] Preferably, the leveling components include a vertical leveling component and a horizontal leveling component. The vertical leveling component is located above the machine base, and the horizontal leveling component is located on the side of the machine base away from the main shaft. The vertical leveling component and the horizontal leveling component are respectively a vertical adjustment cylinder and a horizontal adjustment cylinder. The piston ends of the vertical adjustment cylinder and the horizontal adjustment cylinder are both hinged to the movable end of the mounting shaft, and the cylinder ends of the vertical adjustment cylinder and the horizontal adjustment cylinder are both hinged to the inner wall of the sedimentation tank.

[0011] Preferably, one end of the mounting shaft is provided with a rotating shaft, the transmission sprocket is fixed on the rotating shaft, and the torque sensor is disposed on the movable end of the rotating shaft.

[0012] Preferably, the tensioning device includes a fixed base fixedly disposed on one side of the sedimentation tank. The tensioning device is located on the side of the main shaft away from the transmission assembly. A tensioning screw is threadedly connected to the fixed base. The tensioning screw is horizontally arranged and is provided with a limiting block that cooperates with the fixed base to limit axial movement. The main shaft is coaxially rotatably disposed on a horizontal sliding rod. A connecting sleeve is fixedly connected to the side wall of the horizontal sliding rod, and the connecting sleeve is threadedly connected to the tensioning screw.

[0013] Preferably, the limiting block is a cylindrical tube coaxially fixedly connected to the tensioning screw, and an annular groove is provided in the middle of the limiting block. The fixing seat is connected to the annular groove of the limiting block through a bearing, and the outer diameter of the limiting block is larger than the outer diameter of the bearing.

[0014] Preferably, a horizontal groove is formed on the inner wall of the sedimentation tank, and the end of the horizontal sliding rod is located in the horizontal groove.

[0015] A method for using a deviation warning and automatic adjustment device for a chain scraper includes the following steps: S1. Scraping operation: The main shaft is driven to rotate by an external motor. The main shaft drives the transmission component to rotate through a sprocket, which in turn causes the chain to rotate. The scraper between the two chains moves with the chain and scrapes the sludge on the inner wall of the sedimentation tank. When the scraper pushes the sludge to the top of the inner wall of the sedimentation tank, the sludge enters the skimming pipe. S2. Vertical reset: During the scraping operation, if the transmission component is subjected to a downward pulling force, causing the expansion bolts to loosen, the entire transmission component tilts downward, causing the angle rod to bend downward. The angle rod drives the vertical angle detection strip to move downward. The movable end of the vertical angle detection strip slides downward along the first arc strip, causing the length of the first arc strip connected to the circuit to decrease. The resistance meter reading of the circuit where the first arc strip is located decreases. The tilt angle of the angle rod and the mounting shaft is judged based on the decreased reading. Then, the vertical adjustment cylinder is controlled to contract, pulling the movable end of the mounting shaft to rotate upward until the resistance meter displays the set reading. S3. Horizontal Reset: During scraping operations, if the transmission assembly is subjected to tension towards the inside of the sedimentation tank, causing the expansion bolts to loosen, the entire transmission assembly tilts to one side, causing the angle rod to bend to one side. The angle rod drives the horizontal angle detection strip to move to one side, and the movable end of the horizontal angle detection strip slides to one side along the second arc strip, resulting in a reduction in the length of the second arc strip connected to the circuit. The resistance meter reading in the circuit where the second arc strip is located decreases. Based on the decreased reading, the tilt angle of the angle rod and the mounting shaft is determined. Then, the horizontal adjustment cylinder is controlled to contract, pulling the movable end of the mounting shaft to rotate to the other side until the resistance meter displays the set reading. S4. Tension Adjustment: When the chain stretches due to stress fatigue, the resistance of the scraper increases, causing the torque value detected by the torque sensor to increase. This, in turn, rotates the tension screw, causing the connecting sleeve to move along the axial direction of the tension screw, and drives the main shaft to move through the horizontal sliding rod, thus tensioning the chain.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Non-metallic chain scrapers use chain drive, and their transmission components are installed on the pool wall by expansion bolts. During production and operation, they are prone to tilting due to tension and their own weight, causing the scraper blades to rub against the guide rails, or even overload shutdown or chain derailment. By setting up a detection unit to automatically detect the axial offset of the transmission components, and after detecting the offset, the transmission components are automatically adjusted by leveling components to avoid affecting the water plant's production due to equipment problems.

[0017] 2. Non-metallic chain scrapers use non-metallic traction chains. When the tension is too high, the chain is prone to excessive plastic deformation due to stress fatigue. When the deformation accumulates significantly, the chain will drag the scraper along the ground, rub against the bottom guide rail, and may even hunch over. By installing a torque sensor to detect the chain force and comparing it with the normal tension on the drive sprocket, a sudden increase in tension indicates that the chain needs to be tensioned. This is achieved by using a tensioning device to tighten the chain and ensure the safe operation of the scraper. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-5As shown. This invention proposes a deviation warning and automatic adjustment device for a chain scraper, including a main shaft 1 and a transmission assembly 3 horizontally rotatably mounted at both ends of the top of a sedimentation tank. The transmission assemblies 3 are arranged in pairs and located on opposite inner walls of the sedimentation tank. The main shaft 1 and the transmission assembly 3 are connected by a chain drive, and a scraper plate is connected between the two chains. The transmission assembly 3 is equipped with a detection unit for detecting vertical and horizontal tilt angles and a leveling component. A torque sensor 306 is installed on the transmission assembly 3. The main shaft 1 is rotatably mounted on a tensioning device 4, which is located on the sedimentation tank.

[0026] The chain at the bottom of the chain scraper is located at the bottom of the sedimentation tank. A sprocket is installed on the main shaft 1. The drive motor drives the sprocket to rotate through the chain, thereby rotating the main shaft 1. During the rotation of the main shaft 1, the main shaft 1 is transmitted to the transmission component 3 through the chain. As the chain rotates, it drives the scraper installed between the two chains to scrape the sludge at the bottom of the sedimentation tank and push the sludge to the top of the sedimentation tank. Finally, the sludge falls into the skimming pipe 5 on one side of the sedimentation tank for collection.

[0027] In addition, the detection unit is equipped with an angle adjustment limit. When the offset angle exceeds the angle adjustment limit, the detection unit sends a signal to the alarm and stops the sludge scraper. After that, the staff will perform maintenance on the sludge scraper.

[0028] like Figure 1 and Figure 2 As shown, the transmission assembly 3 is connected to the main shaft 1 via chain drive. The transmission assembly 3 includes a base 301 fixed to the inner wall of the sedimentation tank, a mounting shaft 302 vertically arranged on the base 301 and in a horizontal state, and a transmission sprocket 303 rotatably mounted on the mounting shaft 302. The base 301 is fixed by expansion bolts and has a hollow cylindrical structure. The end wall of the base 301 is in contact with the inner wall of the sedimentation tank, and the detection unit is arranged inside the base 301. The detection unit is arranged inside the base 301 to avoid corrosion by sewage and extend its service life. The mounting shaft 302 has a hollow structure, and the fixed end of the mounting shaft 302 is inserted into the base 301. A stiffening plate connects the bottom of the mounting shaft 302 to the base 301, resulting in high strength of the transmission assembly 3.

[0029] like Figure 1-5As shown, to detect the offset angle of the transmission component 3, an angle rod 308 is coaxially fixedly connected to the inner wall of the connection end between the base 301 and the inner wall of the sedimentation tank. The detection unit includes a vertical angle detection group and a horizontal angle detection group. The vertical angle detection group includes a vertical angle detection strip 309 hinged to one side of the angle rod 308 and a semi-circular first arc strip 312 fixedly disposed on one side of the angle rod 308. The vertical angle detection strip 309 and the first arc strip 312 are both located on the side of the angle rod 308 away from the main shaft 1. The horizontal angle detection group includes a horizontal angle detection strip 310 hinged to the bottom end of the angle rod 308 and a second arc strip 313 fixedly disposed below the angle rod 308. Both the vertical angle detection bar 309 and the horizontal angle detection bar 310 are equipped with reset torsion springs on their hinges. Under the action of elastic force, the vertical angle detection bar 309 and the horizontal angle detection bar 310 are in a state of contact with the first arc-shaped bar 312 and the second arc-shaped bar 313, respectively. The centers of the first arc-shaped bar 312 and the second arc-shaped bar 313 are located at the fixed end of the angle rod 308. The first arc-shaped bar 312 and the vertical angle detection bar 309, and the second arc-shaped bar 313 and the horizontal angle detection bar 310 are two connected circuits, and each circuit is equipped with a resistance meter. The first arc-shaped bar 312 and the second arc-shaped bar 313 are resistance bars.

[0030] The first arc-shaped bar 312 and the second arc-shaped bar 313 are resistor bars with relatively high resistance values. The hinges of the vertical angle detection bar 309 and the horizontal angle detection bar 310, which are hinged to the angle rod 308, are equipped with torsion springs. In this way, when the angle rod 308 rotates vertically, the movable end of the vertical angle detection bar 309 can first make stable contact with the first arc-shaped bar 312. In addition, when the angle rod 308 rotates vertically, the horizontal angle detection bar 310 can rotate around the hinge axis, and under the action of the reset torsion spring, its end is always in contact with the second arc-shaped bar 313, ensuring that the two circuits are always open. Similarly, when the angle rod 308 rotates horizontally, it will not affect the vertical detection.

[0031] like Figure 4 As shown, this is to facilitate the installation of the first arc-shaped strip 312 and the second arc-shaped strip 313. The first arc-shaped strip 312 and the second arc-shaped strip 313 are fixed to the mounting base 311, which is an arc-shaped plate. An arc-shaped opening for accommodating the mounting base 311 is provided on the bottom plate 307 of the base 301, which is in contact with the inner wall of the sedimentation tank. The mounting base 311 is directly connected to the inner wall of the sedimentation tank. Because the mounting base 311 is directly fixed to the inner wall of the sedimentation tank, it has strong stability and will not be affected if the base 301 tilts.

[0032] like Figure 1 and Figure 2As shown, the leveling components are used to adjust the angle of the mounting shaft 302. The leveling components include a vertical leveling component and a horizontal leveling component. The vertical leveling component is located above the base 301, and the horizontal leveling component is located on the side of the base 301 away from the main shaft 1. The vertical and horizontal leveling components are a vertical adjusting cylinder 304 and a horizontal adjusting cylinder 305, respectively. The piston ends of both the vertical and horizontal adjusting cylinders 304 and 305 are hinged to the movable end of the mounting shaft 302, and the cylinder ends of both are hinged to the inner wall of the sedimentation tank.

[0033] Two cylinders are connected to the mounting shaft 302. The angle of the mounting shaft 302 is automatically detected by the detection unit, and the tilt direction and tilt angle of the mounting shaft 302 are determined. Then, the mounting shaft 302 is leveled by the vertical adjustment cylinder 304 and / or the horizontal adjustment cylinder 305, and the mounting shaft 302 is pulled to a direction perpendicular to the inner wall of the sedimentation tank to prevent the chain from falling and causing damage to the chain scraper.

[0034] like Figure 2 As shown, this is to achieve force detection on the transmission sprocket 303 on the mounting shaft 302. One end of the mounting shaft 302 is equipped with a rotating shaft, and the transmission sprocket 303 is fixed to the rotating shaft. The torque sensor 306 is located on the movable end of the rotating shaft. By detecting the rotating shaft through the torque sensor 306, the force on the transmission sprocket 303 can be detected. Based on the force condition, it can be determined whether the chain is in a normal state. If the chain stretches due to stress, the force on the transmission sprocket 303 will increase sharply, and the chain will be tensioned.

[0035] like Figure 1 and Figure 3 As shown, to achieve chain tensioning, the tensioning device 4 includes a fixed base 41 fixedly mounted on one side of the sedimentation tank. The tensioning device 4 is located on the side of the main shaft 1 away from the transmission assembly 3. A tensioning screw 42 is threadedly connected to the fixed base 41. The tensioning screw 42 is horizontally arranged and has a limiting block 43 that cooperates with the fixed base 41 for axial limiting. The main shaft 1 is coaxially rotatably mounted on a horizontal sliding rod 45. A connecting sleeve 44 is fixedly connected to the side wall of the horizontal sliding rod 45 and is threadedly connected to the tensioning screw 42. By rotating the tensioning screw 42, the connecting sleeve 44 moves axially away from the transmission assembly 3, and the horizontal sliding rod 45 pulls the main shaft 1 to move synchronously, thus tensioning the chain.

[0036] like Figure 3As shown, to improve the strength of the tensioning screw 42, the limiting block 43 is a cylindrical component coaxially fixedly connected to the tensioning screw 42. An annular groove is provided in the middle of the limiting block 43. The fixing seat 41 is connected to the annular groove of the limiting block 43 via a bearing. The outer diameter of the limiting block 43 is larger than the outer diameter of the bearing. By fixing the fixing seat 41 to the ground, and then using the fixing seat 41 in conjunction with the limiting block 43 to limit the axial movement of the tensioning screw 42, the tensioning screw 42 is connected to the connecting sleeve 44 via threads, thus ensuring the stability of the connecting sleeve 44.

[0037] In a preferred embodiment of the present invention, to improve the stability of the horizontal sliding rod 45, a horizontal groove is formed on the inner wall of the sedimentation tank, and the end of the horizontal sliding rod 45 is located in the horizontal groove.

[0038] A method for using a deviation warning and automatic adjustment device for a chain scraper includes the following steps: S1. Sludge scraping operation: The main shaft 1 is driven to rotate by an external motor. The main shaft 1 drives the transmission component 3 to rotate through the sprocket, which in turn causes the chain to rotate. The sludge scraper between the two chains moves with the chain and scrapes the sludge on the inner wall of the sedimentation tank. When the sludge scraper pushes the sludge to the top of the inner wall of the sedimentation tank, the sludge enters the skimming pipe 5. S2. Vertical reset: During the scraping operation, if the transmission component 3 is subjected to downward pulling force, causing the expansion bolts to loosen, the entire transmission component 3 will tilt downward, causing the angle rod 308 to bend downward. The angle rod 308 will drive the vertical angle detection strip 309 to move downward. The movable end of the vertical angle detection strip 309 will slide downward along the first arc strip 312, resulting in a reduction in the length of the first arc strip 312 connected to the circuit. The resistance meter reading of the circuit where the first arc strip 312 is located will decrease. Based on the reduced reading, the tilt angle of the angle rod 308 and the mounting shaft 302 will be determined. Then, the vertical adjustment cylinder 304 will be controlled to retract, pulling the movable end of the mounting shaft 302 to rotate upward until the resistance meter displays the set reading. S3. Horizontal Reset: During scraping construction, if the expansion bolts of the transmission assembly 3 loosen due to the tension on the inner side of the sedimentation tank, the entire transmission assembly 3 will tilt to one side, causing the angle rod 308 to bend to one side. The angle rod 308 will drive the horizontal angle detection strip 310 to move to one side, and the movable end of the horizontal angle detection strip 310 will slide to one side along the second arc-shaped strip 313. This will reduce the length of the second arc-shaped strip 313 connected to the circuit, and the resistance meter reading of the circuit containing the second arc-shaped strip 313 will decrease. The angle rod is judged based on the decreased reading. The tilt angle of 308 and mounting shaft 302 is adjusted, and the horizontal adjusting cylinder 305 is retracted to pull the movable end of mounting shaft 302 to rotate to the other side until the resistance meter displays the set reading; S4, tension adjustment: when the chain is stretched due to stress fatigue, the resistance of the scraper increases, which leads to an increase in the torque value detected by torque sensor 306, thereby rotating tension screw 42, causing connecting sleeve 44 to move along the axial direction of tension screw 42, and driving main shaft 1 to move through horizontal sliding rod 45 to tension the chain.

The angle rod (308) will drive the horizontal angle detection strip (310) to move to one side, and the movable end of the horizontal angle detection strip (310) will slide to one side along the second arc strip (313), causing the length of the second arc strip (313) connected to the circuit to decrease, and the resistance meter reading of the circuit where the second arc strip (313) is located to decrease. Based on the decreased reading, the tilt angle of the angle rod (308) and the mounting shaft (302) will be determined, and then the horizontal adjustment cylinder (305) will be controlled to retract, pulling the movable end of the mounting shaft (302) to rotate to the other side until the resistance meter displays the set reading. S4. Tension adjustment: When the chain stretches due to stress fatigue, the resistance of the scraper increases, which leads to an increase in the torque value detected by the torque sensor (306), thereby rotating the tension screw (42), causing the connecting sleeve (44) to move along the axial direction of the tension screw (42), and driving the main shaft (1) to move through the horizontal sliding rod (45) to tension the chain.
