Description

Technical Field

[0001] The present invention relates to the technical field of detection of sludge scraping and suction machines, and in particular to a detection device for a sludge scraper used in a sludge scraping and suction machine. Background Art

[0002] The full-bridge peripheral transmission sludge scraper and suction machine is a kind of sludge scraping and slag skimming equipment suitable for radial flow sedimentation tanks with large diameters in water plants or sewage treatment plants in water supply and drainage projects. It is widely used in radial flow sedimentation tanks with large diameters in water plants or sewage treatment plants in water supply and drainage projects. It can efficiently complete the scraping and collection of sludge at the bottom of the tank and the skimming of scum on the surface of the tank.

[0003] At present, during the operation of the sludge scraper, the scraper blade will contact the sludge and the bottom of the pool for a long time, which will inevitably cause wear. Long-term wear will lead to a decrease in the fit between the scraper blade and the bottom of the pool, making it impossible to effectively scrape up the sludge, resulting in incomplete sludge collection, affecting the sludge removal effect of the entire sedimentation tank, and thus reducing the efficiency and quality of sewage treatment. In addition, since there will be defects of different sizes on the scraper blade, it is difficult to effectively distinguish these worn scrapers. Summary of the Invention

[0049] Working principle: When the scraper blade bodies 5 are subjected to batch defect differentiation detection, multiple scraper blade bodies 5 are installed on the bottom side of the bending frame 39, and then the second motor 25 is controlled to rotate, and the rotating frame 31 will move downward until the supporting bottom rod 37 is connected to the semi-annular groove 14, and then the third motor 351 is controlled to rotate, and the rotating eccentric wheel 33 is moved to the outside of the first telescopic rod 38, and then the fourth motor 353 is controlled to rotate. Driven by the second tooth piece 352, the rotating eccentric wheel 33 will rotate 180 degrees, and the telescopic rod 38 at the corresponding position will be pressed downward during the rotation, and the scraper blade body 5 corresponding to the bottom side will be inserted into the fine sand layer, and then the first motor 21 is controlled to rotate, and the first tooth piece 22 will drive the rotating seat 2 to rotate 180 degrees. During the rotation, the scraper blade body 5 corresponding to the bottom side will be inserted into the fine sand layer. The mud blade body 5 will scrape on the fine sand layer, and the mud scraper body 5 will leave contact marks and movement tracks on the fine sand layer. After rotating 180 degrees, the damage degree of the mud scraper body 5 can be divided into three categories according to the fine sand residue, marks and movement tracks on the fine sand layer: First, there is almost no fine sand residue on the moving path, and the moving marks are uniform and flat, without any unevenness. In this case, the mud scraper body 5 can still be used and does not need to be inspected again; Second, there are many fine sand residues on the moving path, the amount of residual sand is too much, and the marks are wavy and uneven, with unevenness. In this case, the mud scraper body 5 cannot be used and does not need to be inspected again; Third, there are many fine sand residues on the moving path, the amount of residual sand is small, the unevenness of the sand marks is not obvious, and it is difficult to distinguish intuitively, so further inspection is required;

[0050] Analyze the situation of the sand-marked silicone intuitively to identify which situation the scraper body 5 belongs to, then control the rotating eccentric wheel 33 to reverse and restore to the initial state, retract the extended telescopic rod 38, and then control the second motor 25 to rotate, move the adjustment part 3 upward, and then control the rotating seat 2 to perform multiple circular rotations again. The scraper plate 26 will restore the fine sand layer to a flat state. After complete recovery, control the third motor 351 to rotate and move the rotating eccentric wheel 33 to the position of the next telescopic rod 38. Repeat the above operation, and then classify the sand-marked area and record it. Then repeat the operation again to detect, distinguish and record the next scraper body 5.

An outer rotating rod 47 is installed on one side of the bevel gear group 472, and a sixth motor 471 is provided at one end of the outer rotating rod 47 to control the shift screw rods 463 on both sides to move simultaneously. A bevel gear group 472 is connected between the two shift screw rods 463 and the outer rotating rod 47 to ensure that the contact rope 45 moves simultaneously.

[0055] The limiting plate 41 is also rotatably connected to a linkage rod 421, and a plurality of support plates 422 are fixedly installed on the outer surface of the linkage rod 421. Two inclined sensing pressure rods 42 are installed on the support plates 422. The sensing pressure rods 42 and the scraper body 5 are parallel to each other to ensure that the contact rope 45 is connected to the scraper body 5. The sensing pressure rod 42 is connected to the top surface of the contact rope 45, and its height position is adapted to the scraper body 5. A driving gear is installed on one end of the linkage rod 421, and a second cylinder 423 is also installed on the limiting plate 41. A movable tooth plate 424 is installed at the output end of the second cylinder 423. The movable tooth plate 424 and the driving gear mesh with each other to rotate the angle of the sensing pressure rod 42. The sensing pressure rod 42 is a sensing rod when in contact, and an array of thin film pressure sensors is arranged therein, which can detect the contact position of the contact rope 45 with it, and collect the vibration characteristics of the contact rope 45 during movement through an accelerometer.

[0056] Working principle: When all the tests in Example 1 are completed, the second motor 25 is controlled to rotate, the adjusting member 3 is raised to the specified height, and then the rotating seat 2 is controlled to rotate again. During the rotation, the ball 361 will first be connected to the arc groove 121 to support the rotating frame 31. At this time, the first cylinder 341 is controlled to retract backward. When the bevel gear 36 and the bevel gear ring 122 contact, the two are engaged with each other, and the rotating frame 31 will begin to flip. During the flipping process, the spring block 343 will retract backward. When the rotating frame 31 flips one hundred and eighty degrees, it is stuck in the tail rod 311 again. At this time, the first cylinder 341 is controlled to extend so that its telescopic end is connected to the outer card shell 342, and the positioning of the rotating frame 31 is completed again. Then the rotating seat 2 is continuously rotated to move the rotating frame 31 to the detection position on the bottom side of the rotation detection member 4.

[0057] Then, according to the test results in Example 1, the scraper body 5 that needs further testing is tested;

[0058] The third motor 351 is controlled to rotate, and the positioning screw 35 will move the rotating eccentric wheel 33 to the outside of the telescopic rod 38 at the corresponding position, and then the fourth motor 353 is controlled to rotate, and the corresponding telescopic rod 38 is pushed outward, and the corresponding scraper body 5 will extend upward and stop after extending to the specified height, and then the fifth motor 43 is controlled to rotate, and the contact rope 45 with the thickest diameter is first rotated to a horizontal position on the right side. At this time, the protrusion 453 at the tail end of the contact rope 45 will rotate between the moving blocks 464, and then the sixth motor 471 is controlled to rotate. Under the rotation of the outer rotating rod 47, the shift screw 463 will start to rotate, and the moving block 464 will drive the contact rope 45 to move to one end of the scraper body 5 and then stop, and then the second cylinder 423 is controlled to retract upward, and the movable tooth plate 424 will drive the support plate 422 to flip during the upward movement, and the induction pressure rod 42 will The second motor 471 is controlled to rotate, and the contact rope 45 is connected to the scraper body 5. When the motor 471 moves to the defect area, if the opening of the defect is larger than the diameter of the contact rope 45, the contact rope 45 will be trapped in it when the contact rope 45 passes through. At this time, the two ends of the contact rope 45 are still moving at a constant speed. At this time, there is a large difference between the contact positions of the multiple sensing pressure rods 42 and the contact rope 45. After receiving the signal of the large difference, the controller will stop the movement of the contact rope 45. It is concluded that under the detection movement of the contact rope 45 with the thickest diameter, a defect with a large diameter is detected on the scraper body 5, and it can no longer be used. The scraper body 5 is classified by defect size.

[0059] If the opening at the defect is smaller than the diameter of the contact rope 45, the contact rope 45 will get stuck when it passes through. After the jam, it will quickly recover and continue to be tested. When it is jammed, the sensing pressure rod 42 will sense the vibration generated by the contact rope 45, and the signal will be transmitted back to the controller and recorded. The position of the contact rope 45 will then be restored to the rotating adjustment plate 44, and the fifth motor 43 will be controlled to rotate and switch to the next contact rope 45 with a slightly smaller diameter to test the scraper body 5 again. The test results are again divided into the two situations mentioned above: one is that the defect completely jams the contact rope 45 and it can no longer be used; the other is that a jam occurs during the movement, and a slightly thinner contact rope 45 is replaced again for testing; until all contact ropes 45 of different thicknesses on the rotating adjustment plate 44 are tested, if there is no jamming, it means that the scraper body 5 can continue to be used, and then the scraper bodies 5 with jammed contact ropes 45 of different thicknesses are classified for subsequent unified maintenance and other operations;

[0060] After completing the inspection of the scraper body 5 on the rotating stand 31, control the rotating eccentric wheel 33 to recover, lower the scraper body 5, and then adjust the height of the adjusting member 3. After adjusting to the specified position, control the rotating seat 2 to rotate again. The bevel gear 36 will contact the bevel gear ring 122 on the other side. Repeat the above operation again to rotate the rotating stand 31 180 degrees to restore it to its original position. Then remove the inspected scraper body 5, replace it with the next batch and test it again.
