DETAILED DESCRIPTION

[0024] The following specific embodiments illustrate the implementation of the utility model, and those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0025] Please refer to Figures 1 to 3The utility model provides a reciprocating type slag scraper, including the guide rail 100 who sets respectively in air floatation pond left and right two sides, the guide rail 100 includes horizontal section 120 and the oblique section 110 of oblique to the top, the oblique section 110 is located air floatation pond's front end, the oblique section 110 below is equipped with corresponding sludge groove bevel 800, the guide rail 100 is installed with first travelling crane 200 and second travelling crane 300, first travelling crane 200 is close to the oblique section 110 of guide rail 100 (i.e. first travelling crane 200 is located front end, and second travelling crane 300 is located rear end), be equipped with the drive assembly 400 for driving it along the guide rail 100 movement on second travelling crane 300, first travelling crane 200 and second travelling crane 300 are connected through hinge 210 before, first travelling crane 200 and second travelling crane 300 are also equipped with pneumatic lifting assembly 500 for controlling the lifting of scraper 540, the front and rear ends of air floatation pond are also equipped with switch 700 with first travelling crane 200 / second travelling crane 300 cooperation touch, and the switch 700 of front end is used for controlling scraper 540 lifting and second travelling crane 300 retreat, and the switch 700 of rear end is used for controlling scraper 540 falling and second travelling crane 300 advancing.

[0026] Because first travelling crane 200 and second travelling crane 300 are connected with hinge 210, first travelling crane 200 can rotate around second travelling crane 300 through hinge 210. Drive assembly 400 drives second travelling crane 300 to make linear motion along the horizontal section 120 of guide rail 100, under the impetus of second travelling crane 300, first travelling crane 200 can naturally lift along the oblique section 110 of guide rail 100, and scraper 540 suspended below first travelling crane 200 can along sludge groove bevel 800 and floatage slag into bevel, and the slag is scraped more cleanly and completely, and the disturbance to separation zone is small.

[0027] Further, the pneumatic lifting assembly 500 includes air pump 510, electromagnetic valve and multiple groups of air cylinders 520, one group of air cylinders 520 is arranged on the first travelling crane 200, and the scraper 540 is connected to the telescopic end of the air cylinder 520; one group of air cylinders 520 is arranged at the front and rear ends of the second travelling crane 300 respectively, the telescopic ends of the two groups of air cylinders 520 are connected through the scraper frame 530, and multiple scrapers 540 are suspended below the scraper frame 530; the air pump 510 is installed on the second travelling crane 300, and the air pump 510 is connected to each group of air cylinders 520 for controlling the synchronous lifting of the scraper 540.

[0028] This solution utilizes compressed air from an air pump 510 as a power source. The pressure and direction of the air are controlled by a solenoid valve, driving the cylinder 520 to complete the telescopic movement. This pneumatic lifting assembly has a simple and lightweight structure, is easy to install and maintain, and operates smoothly with low noise. Simultaneously, by setting a scraper frame 530 between the two sets of cylinders 520, multiple scrapers 540 are suspended below the scraper frame 530. The coverage of the scrapers 540 is equivalent to that of a full-coverage chain-plate scraper, resulting in high scraping efficiency—more than 10 times that of a traditional track-type scraper. With multiple scrapers 540 working simultaneously, the scraping is cleaner and more thorough, leading to better scraping results.

[0029] Furthermore, the width of the scraper 540 is the same as the width of the flotation tank, and when the scraper 540 moves forward, its bottom edge is below the sewage level.

[0030] Furthermore, the first traveling carriage 200 and the second traveling carriage 300 are slidably mounted on the guide rail 100 on both sides by the anti-deviation and derailment assembly 600.

[0031] For details, please refer to Figure 4 The guide rail 100 is L-shaped and cooperates with the anti-derailment assembly 600. The anti-derailment assembly 600 includes a connecting seat 610, a horizontal adjusting member 620, a vertical adjusting member 630, a support wheel 640, and a side wheel 650. The side wheel 650 is mounted on the connecting seat 610 in a translational adjustment manner through the horizontal adjusting member 620, and the side wheel 650 contacts the side of the guide rail 100. The support wheel 640 is mounted on the connecting seat 610 in a height adjustment manner through the vertical adjusting member 630, and the support wheel 640 contacts the bottom edge of the guide rail 100.

[0032] Traditional overhead scrapers require additional weights to increase friction with the guide rail 100 to prevent slippage and derailment, thus incurring higher costs and proving difficult to manage after derailment. This solution, however, adds anti-deviation / derailment components 600 to both sides of the overhead scraper. Adjusting the height of the support wheels 640 controls the height balance of the left and right sides of the scraper; adjusting the side wheels 650 changes the width of the scraper, reducing the width error between the scraper and the pool body, thus confining the scraper to the guide rail 100 and ensuring its straight-line movement.

[0033] Furthermore, at least one set of anti-derailment components 600 is provided on each side of the first traveling car 200, and at least two sets of anti-derailment components 600 are provided on each side of the second traveling car 300.

[0034] Furthermore, the drive assembly 400 includes a drive motor 410 and a transmission chain 420. The drive motor 410 is connected to the shaft of one set of support wheels 640 via the transmission chain 420. This solution uses a rear-drive configuration to drive the second carriage 300, thereby driving the first carriage 200, effectively ensuring smooth movement. The transmission chain 420 also provides a smoother transmission with less noise.

[0035] Working principle: The drive motor 410 drives the second trolley 300 forward through the transmission chain 420. The second trolley 300 pulls the first trolley 200 in front of it through the hinge 210, so that the first scraper 540 and the multiple scrapers 540 suspended on the scraper frame 530 move forward together to scrape sludge. When it travels to above the sludge trough inlet 800, the first trolley 200 is naturally lifted along the inclined section 110 of the guide rail 100 by the push of the second trolley 300. The first scraper 540 suspended below the first trolley 200 throws the scum into the trough along the sludge trough inlet 800. After skimming is complete, the first trolley 200 touches the front switch 700, at which point the drive motor 410 stops, and the pneumatic lifting assembly 500 raises the scraper 540 above the liquid level. After the scraper 540 is raised, the drive motor 410 reverses, causing the first trolley 200 and the second trolley 300 to retreat to a designated position along the guide rail 100. Since the scraper 540 is already raised to the liquid level, the scum will not be disturbed when the scraper retreats. When the scraper retreats to touch the rear switch 700, the drive motor 410 stops, and the pneumatic lifting assembly 500 lowers the scraper 540. After the scraper 540 is in position, the drive motor 410 drives the second trolley 300 forward, and this cycle repeats to achieve scum skimming.

[0036] In summary, the slag scraper of this invention has a simple structure. By setting an inclined section at the front end of the guide rail, the first trolley can be naturally lifted along the inclined section of the guide rail. The scraper suspended below the first trolley can then skim the scum into the inclined opening of the sludge trough, ensuring thorough and clean scraping with minimal disturbance to the separation zone. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
