[0002] Rotary screens are mainly used in sewage treatment to intercept and remove larger suspended matter and floating matter in sewage. They play an important role in the primary stage of sewage treatment.

[0003] For example, a Chinese patent discloses: a rotary grille for a sewage treatment device, patent number: CN218521084U, which is made by optimizing the stainless steel frame of the fixed bracket to make a grille mesh belt that can be manually rotated on site, equipped with corrosion-resistant and different forms of bearings and shafts, and driven by a motor and a reducer to drive the gears, conveyor chain and rotary grille to rotate. At the same time, the roller brush rotates and cooperates with the high-pressure nozzle to wash the rotary grille. The dirt and blockages that fall off the washing are collected by the sewage collector and discharged into the sewage well, and discharged uniformly by the sewage pump.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: as mentioned above, when the grille is damaged during use and needs to be replaced, the device can only remove the grille as a whole and then reinstall it. The installation and disassembly process is relatively cumbersome and inconvenient for replacing the grille. Utility Model Content

[0023] The embodiment of the present application provides a rotary grate for sewage treatment, which effectively solves the problem that when the grate is damaged during use and needs to be replaced, the device can only remove the grate as a whole and then reinstall it. The installation and disassembly process is relatively cumbersome and inconvenient for replacing the grate. The support rod is flipped counterclockwise to keep the support rod away from the side wall of the threaded sleeve, and then the threaded sleeve is rotated counterclockwise to rotate the threaded sleeve away from the side wall of the grate, and the threaded sleeve is pulled out of the inside of the clamping ring. The threaded sleeve will slide along the side wall of the third ring and the inner wall of the second ring to complete the operation of disassembling the grate. Otherwise, the grate will be removed. The grille is assembled so that it is modularized for easy installation and disassembly, thereby achieving the function of easy installation and disassembly. When the water flow impacts the rotating blade, the rotating blade drives the first ring and the third ring to rotate clockwise, the first ring drives the clamping ring to rotate clockwise, the clamping ring drives the connecting rod to rotate clockwise, the connecting rod drives the second ring to rotate clockwise, the grille is inserted into the clamping ring, and the clamping ring drives the grille to rotate clockwise. When the grille rotates clockwise to the cleaning rod, the cleaning rod removes impurities on the inner wall of the grille, and the impurities fall into the drain outlet and are discharged from the inside of the device, thereby achieving the function of removing impurities.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when the grille is damaged during use and needs to be replaced, the device can only dismantle the grille as a whole and then reinstall it, and the installation and disassembly process is relatively cumbersome, which is not convenient for replacing the grille. The overall idea is as follows: A rotating grille for sewage treatment includes a bracket 11, and a support shaft 12 is fixedly installed on the top of the bracket 11 to facilitate supporting the entire device.

[0026] The side wall of the support shaft 12 is fixedly mounted with a collar 13, the number of the collars 13 is two, the side walls of the two collars 13 are fixedly mounted with rotating blades 14, the side wall of the front rotating blade 14 is fixedly mounted with a fixing structure, the fixing structure includes a first ring 15, the side wall of the first ring 15 is fixedly mounted with a clamping ring 16, the end of the clamping ring 16 close to the support shaft 12 is fixedly mounted with a connecting rod 17, the end of the connecting rod 17 away from the clamping ring 16 is fixedly mounted with a second ring 18, the side wall of the rear rotating blade 14 is fixedly mounted with a third ring 19, and the inside of the clamping ring 16 is plugged with The grille 21 has a threaded sleeve 22 installed on the side wall of the grille 21. The support rod 23 is flipped counterclockwise to make the support rod 23 away from the side wall of the threaded sleeve 22. The threaded sleeve 22 is then rotated counterclockwise to rotate the threaded sleeve 22 away from the side wall of the grille 21. The threaded sleeve 22 is pulled out from the inside of the clamping ring 16. The threaded sleeve 22 will slide along the side wall of the third ring 19 and the inner wall of the second ring 18 to complete the operation of disassembling the grille 21. Conversely, the grille 21 is assembled to make the grille 21 modular and easy to install and disassemble, thereby achieving the function of easy installation and disassembly.

[0027] A support rod 23 is rotatably installed on the side wall of the support shaft 12, a torsion spring is inserted inside the support shaft 12, and the torsion spring is sleeved on the side wall of the support rod 23, a cleaning rod 24 is fixedly installed on the side wall of the support shaft 12, and a sewage outlet 25 is opened on the side wall of the support shaft 12. When the water flow impacts the rotating blade 14, the rotating blade 14 drives the first ring 15 and the third ring 19 to rotate clockwise, the first ring 15 drives the clamping ring 16 to rotate clockwise, the clamping ring 16 drives the connecting rod 17 to rotate clockwise, and the connecting rod 17 drives the second ring 18 to rotate clockwise, the grille 21 is inserted inside the clamping ring 16, and the clamping ring 16 drives the grille 21 to rotate clockwise. When the grille 21 rotates clockwise to the cleaning rod 24, the cleaning rod 24 removes the impurities on the inner wall of the grille 21, and the impurities fall into the sewage outlet 25 and are discharged from the inside of the device, thereby achieving the function of removing impurities.

[0028] In view of the problems existing in the prior art, the utility model provides a rotary grille for sewage treatment. The support rod 23 is turned counterclockwise to make the support rod 23 away from the side wall of the threaded sleeve 22, and then the threaded sleeve 22 is rotated counterclockwise to rotate the threaded sleeve 22 away from the side wall of the grille 21, and the threaded sleeve 22 is pulled out from the inside of the clamping ring 16. The threaded sleeve 22 will slide along the side wall of the third ring 19 and the inner wall of the second ring 18 to complete the operation of disassembling the grille 21. Conversely, the grille 21 is assembled to make the grille 21 modular and easy to install and disassemble, thereby achieving the function of easy installation and disassembly. When the water flow impacts the rotating blade 14, the rotating blade 14 drives the first ring 15 and the third ring 19 to rotate clockwise, the first ring 15 drives the clamping ring 16 to rotate clockwise, the clamping ring 16 drives the connecting rod 17 to rotate clockwise, the connecting rod 17 drives the second ring 18 to rotate clockwise, the grille 21 is inserted into the clamping ring 16, the clamping ring 16 drives the grille 21 to rotate clockwise, when the grille 21 rotates clockwise to the cleaning rod 24, the cleaning rod 24 removes the impurities on the inner wall of the grille 21, and the impurities fall into the drain outlet 25 and are discharged from the inside of the device, thereby achieving the function of removing impurities.

[0029] Working principle:

[0030] The first step is to flip the support rod 23 counterclockwise to make the support rod 23 away from the side wall of the threaded sleeve 22, and then rotate the threaded sleeve 22 counterclockwise to rotate the threaded sleeve 22 away from the side wall of the grille 21, and pull the threaded sleeve 22 out of the inside of the clamping ring 16. The threaded sleeve 22 will slide along the side wall of the third ring 19 and the inner wall of the second ring 18 to complete the operation of disassembling the grille 21. Conversely, assemble the grille 21 to make the grille 21 modular and easy to install and disassemble, thereby achieving the function of easy installation and disassembly.

[0031] In the second step, when the water flow hits the rotating blade 14, the rotating blade 14 drives the first ring 15 and the third ring 19 to rotate clockwise, the first ring 15 drives the clamping ring 16 to rotate clockwise, the clamping ring 16 drives the connecting rod 17 to rotate clockwise, the connecting rod 17 drives the second ring 18 to rotate clockwise, the grille 21 is inserted into the clamping ring 16, the clamping ring 16 drives the grille 21 to rotate clockwise, when the grille 21 rotates clockwise to the cleaning rod 24, the cleaning rod 24 removes the impurities on the inner wall of the grille 21, and the impurities fall into the drain outlet 25 and are discharged from the inside of the device, thereby achieving the function of removing impurities.
