Technical Field

The present application relates to the field of sewage treatment equipment, and in particular to a rotary grille cleaning device.

Background Art

The rotary screen, also known as the rotary screen dirt remover, can continuously and automatically intercept and remove various large solid impurities in sewage. It is used for pre-pump dirt removal in urban sewage stations and sewage treatment plants. The rotary screen has a compact structure, stable operation, easy operation, and automatic unloading. It is an ideal and necessary pre-pump dirt removal equipment.

The rotary screen includes a screen shell and a screen assembly. The screen assembly is rotatably installed in the screen shell. A driving roller is arranged on one side of the top of the screen assembly. A driving motor is arranged on the screen shell. The driving motor drives the driving roller to rotate through a belt, thereby driving the screen assembly to rotate. Large volume impurities in the sewage are brought to the top by the screen assembly and gradually fall off from the top of the screen assembly.

In actual use, since the grid pitch of some screens is relatively small, solid impurities attached to the bars cannot fall off normally. As the screen assembly rotates, these impurities will pass over the screen and enter the water collection well, affecting the normal operation of subsequent water pumps.

DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with Figures 1-2.

The embodiment of the present application discloses a rotary grille cleaning device, referring to FIG1 , comprising an active roller 1, a driven roller 2, a transmission belt 3 and a cleaning belt 4. The active roller 1 and the driven roller 2 are installed in parallel in a grille housing and are located below a grille assembly. The transmission belt 3 is sleeved on the active roller 1 and the driving roller, and the cleaning belt 4 is sleeved on the active roller 1 and the driven roller 2. A plurality of soft scrapers 5 are arranged at intervals on the outer peripheral side of the cleaning belt 4 along the length direction, and the soft scrapers 5 located between the cleaning belt 4 and the grille assembly abut against the grille assembly.

The driving motor on the grille housing drives the driving roller to rotate, and the active roller 1 rotates synchronously under the drive of the transmission belt 3, thereby driving the cleaning belt 4 and the driven roller 2 to rotate, and the rotation direction of the cleaning belt 4 is consistent with the rotation direction of the grille assembly, that is, the bars on the grille assembly close to the cleaning belt 4 and the soft scrapers 5 on the cleaning belt 4 close to the grille assembly move toward each other. As the grille assembly and the cleaning belt 4 rotate, multiple soft scrapers 5 continuously scrape across the bars, thereby scraping off impurities attached to the bars to prevent the impurities from entering the water collection well later.

In this embodiment, the soft scraper 5 is made of a flexible material, preferably a rubber material with certain toughness and elasticity, in order to prevent the rigid scraper from scratching the grille assembly or getting stuck with the grille assembly, thereby ensuring the cleaning effect and improving the stability of the device operation.

Further, referring to Fig. 1, a plurality of scraping teeth 6 are formed on one side of the soft scraper 5 close to the grille assembly, and the scraping teeth 6 are arranged in a cone shape on the side close to the grille assembly. The scraping teeth 6 can extend into the gaps between the bars, thereby scraping away impurities in the gaps between the bars, thereby improving the cleaning effect of the grille assembly.

In this embodiment, the scraping teeth 6 are evenly distributed along the side of the scraper plate. The evenly distributed scraping teeth 6 can provide a more stable scraping effect, further improving the cleaning effect of impurities attached to the grid assembly.

In other embodiments, the scraping teeth 6 may also be arranged corresponding to the gaps of the grille components, and the scraping teeth 6 may extend into the gaps corresponding to the grille components. The above structure can improve the coverage of the scraping teeth 6 on the scraping effect of the gaps between the bars, and further improve the scraping effect.

1, a plurality of soft scrapers 5 are evenly distributed along the length direction of the cleaning belt 4. The above structure can continuously and uninterruptedly scrape away impurities attached to the grid assembly, and the scraping effect is more continuous and more stable.

1 and 2 , a collecting box 7 is provided below the grille housing, and the top of the collecting box 7 is open. After the soft scraper 5 scrapes the impurities from the grille assembly, the impurities fall into the box from the top opening of the collecting box 7 .

1 and 2, a discharge port 9 is provided on one side of the collection box 7, and a door is provided at the discharge port 9. When a large amount of impurities are accumulated in the collection box 7, the impurities can be taken out of the collection box 7 by opening the door, which is convenient to use.

Further, referring to Figures 1 and 2, a sieve plate 8 is provided in the collection box 7, which divides the interior of the collection box 7 into a storage chamber 71 located at the top and a drainage chamber 72 located at the bottom. The drainage chamber 72 is connected to a drainage pipe 10, and the discharge port 9 is opened on the side of the collection box 7 located at the storage chamber 71 and is connected to the storage chamber 71.

After the scraped impurities enter the storage chamber 71, they fall on the sieve plate 8, and the water attached to the impurities flows through the sieve plate 8 into the drainage chamber 72 and is discharged from the drainage pipe 10. The sieve plate 8 is used to separate the water attached to the impurities, reducing the burden of the subsequent unified treatment of impurities.

The implementation principle of a rotary grille cleaning device disclosed in an embodiment of the present application is as follows: when the driving motor drives the grille assembly to rotate, the driving roller 1 is driven to rotate through the transmission belt 3 synchronously, and then the cleaning belt 4 is driven to rotate. The soft scraper 5 and the scraping teeth 6 on the outer peripheral side of the cleaning belt 4 continuously scrape off the impurities attached to the grille assembly. The scraped impurities fall into the collection box 7 and are finally processed uniformly.

The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
