Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0024] like Figure 1-6As shown, the present invention provides a technical solution: a sludge suction scraper for sewage treatment, including a fixed plate 1. The support legs 2 are fixedly installed at the bottom of the fixed plate 1. There are four support legs 2, and the four support legs 2 are all the same in shape and size. The four support legs 2 are fixedly installed at the four corners of the bottom of the fixed plate 1, and the support legs 2 support the position of the whole device. The processing chamber 3 is fixedly installed on the top of the fixed plate 1; And the processing component 4 is located on the inner wall of the processing chamber 3; The processing component 4 includes an adjustment mechanism 41 installed on the side wall of the processing chamber 3. The adjustment mechanism 41 includes a rectangular block 411, which is fixedly installed on the side wall of the rotating rod 435. A long plate 412 is fixedly installed on the side wall of the rectangular block 411. A cylinder 414 is slidably installed on the inner wall of the long plate 412. A horizontal plate 413 is fixedly installed on the side wall of the cylinder 414. A hinge block 415 is fixedly installed on the top of the horizontal plate 413. A second hinge block 418 is hinged to the first hinge block 415 via a connecting rod 416. A sleeve block 419 is fixedly installed on the side wall of the second hinge block 418. The inner wall of the sleeve block 419 is slidably connected to the side wall of the rotating rod 435. A cylinder 417 is fixedly installed on the top of the rectangular block 411. The cylinder 417 is connected to the top of the rectangular block 411 via a telescopic rod at its output end. The bottom of the connecting block 419 is fixedly connected, and there are two long plates 412. The two long plates 412 are symmetrically arranged with respect to the left and right middle surfaces of the rectangular block 411. The operator can adjust the position of the scraper 434 according to the size of the inner wall of the processing chamber 3. The operator opens the cylinder 417. Under the combined action of the connecting block 419, the second hinge block 418, the connecting rod 416, the first hinge block 415, the horizontal plate 413, the cylinder 414, and the stirring rod 433, the cylinder 417 can effectively adjust the scraper 434 to a suitable position. This solves the problem that the existing device uses a motor to drive the connecting rod and the side scraper to rotate, but the length of the connecting rod is always fixed, making it difficult to effectively scrape the sludge on the inner wall of sedimentation tanks of different sizes, which leads to certain limitations of the device. The operator can adjust the position of the scraper 434 according to the inner wall size of the processing chamber 3. The operator opens the cylinder 417, which drives the position of the sleeve block 419 to descend through the telescopic rod at the output end. When the sleeve block 419 descends, it will drive the position of the second hinge block 418 to descend. The second hinge block 418 presses one end of the connecting rod 416. The connecting rod 416 effectively presses one end of the first hinge block 415. The first hinge block 415 drives the position of the horizontal plate 413 to move. The horizontal plate 413 further drives the position of the cylinder 414 to move. The cylinder 414 further drives the position of the stirring rod 433 to move. The stirring rod 433 effectively drives the position of the scraper 434 to move, effectively adjusting the scraper 434 to a suitable position. Example 2

[0025] Based on Example 1, a scraping mechanism 43 is installed on the inner wall of the processing chamber 3. The scraping mechanism 43 is located on the side wall of the adjusting mechanism 41 and is connected to the adjusting mechanism 41. The scraping mechanism 43 includes a motor 436 and a stirring rod 433. The motor 436 is installed on the inner wall of the arc-shaped block 424. The motor 436 drives a rotating rod 435 through a rotating shaft at its output end. A base 431 is rotatably mounted on the bottom of the rotating rod 435. Four suction cups 432 are fixedly mounted on the bottom of the base 431. The four suction cups 432 are of equal shape and size and are evenly distributed on the bottom of the base 431. The bottom of the suction cup 432 is positioned in contact with the bottom inner side of the processing chamber 3. One end of the stirring rod 433 is fixedly installed on the side wall of the cylinder 414, and the other end of the stirring rod 433 is fixedly installed with a scraper 434. The side wall of the scraper 434 is slidably connected to the inner wall of the processing chamber 3. The scraper 434 can scrape the sludge on the inner wall of the processing chamber 3. The operator supports the bottom of the motor 436 with the suction cup 432 and the chassis 431, and then the motor 436 can be turned on. Under the combined action of the rotating rod 435, the stirring rod 433 and the scraper 434, the motor 436 effectively scrapes the sludge on the side wall of the processing chamber 3. The operator installs the suction cup 432 on the inner bottom of the processing chamber 3, with the bottom of the suction cup 432 in contact with the inner bottom of the processing chamber 3. Then the motor 436 can be turned on. The motor 436 drives the rotating rod 435 to move through the rotating shaft at the output end. The rotating rod 435 effectively drives the stirring rod 433 to rotate, and the stirring rod 433 further drives the scraper 434 to rotate. Example 3

[0026] Based on Embodiments 1 and 2, a stabilizing mechanism 42 is installed at the top of the processing chamber 3. The inner wall of the stabilizing mechanism 42 contacts the side wall of the scraping mechanism 43. The stabilizing mechanism 42 includes a stabilizing block 421, which is installed on the side wall of the processing chamber 3. A long rod 422 is fixedly installed on the side wall of the stabilizing block 421. When the operator installs the motor 436, the position of the stabilizing block 421 is adjusted according to the size of the processing chamber 3. First, the position of the stabilizing block 421 is pulled. Under the combined action of the stabilizing block 421, the long rod 422, and the compression spring 427, the inner wall of the stabilizing block 421 contacts the side wall of the processing chamber 3, which can effectively stabilize the position of the arc-shaped block 424. The stabilizing block 421 can be installed according to the size of the processing chamber 3 to facilitate the operator's better installation of the motor 436. The other end of the long rod 422 is fixedly installed with a compression spring 427. A snap-fit ​​block 423 is fixedly installed at the other end of the compression spring 427, and an arc-shaped block 424 is fixedly installed at the other end of the snap-fit ​​block 423. When the inner wall of the stabilizing block 421 contacts the side wall of the processing chamber 3, the position of the motor 436 can be directly determined. The inner wall of the stabilizing block 421 is slidably connected to the side wall of the processing chamber 3. There are two stabilizing blocks 421, and the two stabilizing blocks 421 are of equal shape and size. The side wall of the long rod 422 is slidably connected to the top of the processing chamber 3. The inner wall of the snap-fit ​​block 423 is slidably connected to the side wall of the long rod 422. The inside of the arc-shaped block 424 is fixedly connected to the side wall of the motor 436. The arc-shaped block 424 can effectively support the position of the motor 436. When the operator installs the motor 436, the two arc-shaped blocks 424 are snapped together by bolts. The operator can disassemble the position of the arc-shaped block 424 to facilitate the disassembly and maintenance of the motor 436 and improve the performance of the device. When the operator installs the motor 436, and adjusts the position of the stabilizing block 421 according to the size of the processing chamber 3, the stabilizing block 421 is first pulled. The stabilizing block 421 moves the position of the long rod 422. When the bottom of the long rod 422 contacts the top of the processing chamber 3, the stabilizing block 421 can be pulled directly. At this time, the compression spring 427 will move the position of the long rod 422. The long rod 422 moves the stabilizing blocks 421 on both sides towards the middle position. The inner wall of the stabilizing block 421 contacts the side wall of the processing chamber 3, effectively stabilizing the position of the arc-shaped block 424.
