All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 Figures 1-5 , an embodiment provided by the present utility model: An urban domestic sewage treatment system, comprising: a support frame 1, a stirring tank 2 fixedly connected to the top of the support frame 1, a driving assembly 4 fixedly connected to the inside of the stirring tank 2, a rotating base 5 movably connected to the outer surface of the driving assembly 4, a rotating rod 7 fixedly connected to the top of the rotating base 5, a fixing member 8 fixedly connected to the outer surface of the rotating rod 7, a connecting plate 9 fixedly connected to the outer surface of the fixing member 8, a connecting block 10 fixedly connected to the outer surface of the fixing member 8, a sleeve plate 11 movably connected to the outer surface of the connecting block 10, a fixing bolt 12 movably connected to the inside of the sleeve plate 11, a fixing plate 13 fixedly connected to the side surface of the sleeve plate 11, a cleaning plate 15 movably connected to the inside of the fixing plate 13, a limiting block 17 movably connected to the side surface of the cleaning plate 15, a first limiting plate 18 fixedly connected to the inside of the limiting block 17, and a first spring column 19 fixedly connected to the outer surface of the first limiting plate 18.

[0025] Specifically, through the arrangement of the connecting block 10 and the sleeve plate 11, the sleeve plate 11 can be sleeved above the connecting block 10, and then fixed by the fixing bolt 12, so as to realize the movable connection between the fixing member 8 and the fixing plate 13.

[0026] Please refer to Figures 1-5 Figures 1-5 , a filter screen 6 is fixedly connected to the inside of the stirring tank 2, and a stirring cover 3 is movably connected to the outer surface of the stirring tank 2.

[0027] Specifically, through the arrangement of the support frame 1, it can effectively play a role in supporting the stirring tank 2, so that the stirring tank 2 can maintain stability during stirring, thereby effectively improving the practicability of the device.

[0028] Please refer to Figures 1-5 Figures 1-5 , a placement groove 14 is formed in the inside of the fixing plate 13, and the cleaning plate 15 is slidably connected to the inside of the placement groove 14.

[0029] Specifically, through the arrangement of the placement groove 14, when the cleaning plate 15 is inserted into the inside of the fixing plate 13, the placement groove 14 can effectively play a guiding role, making the insertion of the cleaning plate 15 smoother, thereby effectively improving the fluency of the device.

[0030] Please refer to Figures 1-5 Figures 1-5 , a first limiting plate 18 is fixedly connected to the bottom of the cleaning plate 15, four groups of limiting blocks 17 are movably connected to both sides of the cleaning plate 15, and a pull ring 16 is fixedly connected to the side of the cleaning plate 15 away from the first limiting plate 18.

[0031] Specifically, through the setting of the first limiting plate 18, during stirring and filtering, the first limiting plate 18 continuously cleans the surface of the filter plate 24, thereby preventing blockage on the surface of the filter plate 24.

[0032] Please refer to Figures 1-5 , a fixed base 20 is fixedly connected to the bottom of the support frame 1, and a second limiting plate 21 is fixedly connected to the side of the fixed base 20 away from the support frame 1.

[0033] Specifically, through the setting of the fixed base 20, the fixed connection between the support frame 1 and the second limiting plate 21 can be effectively realized, thereby realizing the stable connection of the device.

[0034] Please refer to Figures 1-5 , a second spring column 22 is fixedly connected to the outer surface of the second limiting plate 21, and a support seat 23 is fixedly connected to the outer surface of the second spring column 22.

[0035] Specifically, through the setting of the second spring column 22, during the stirring operation of the stirring tank 2, the second spring column 22 can play a role in shock absorption and buffering in a timely and effective manner, thereby effectively protecting the integrity of the device.

[0036] Please refer to Figures 1-5 , the second spring column 22 is fixedly connected between the second limiting plate 21 and the support seat 23, and one end of the second spring column 22 away from the second limiting plate 21 is fixedly connected to the inner wall of the support seat 23.

[0037] Specifically, through the setting of the second limiting plate 21, when the second spring column 22 is reset, the second limiting plate 21 can form a limiting effect with the support seat 23, thereby avoiding the disconnection between the fixed base 20 and the support seat 23, resulting in damage to the device.

[0038] Please refer to Figures 1-5 , the first limiting plate 18 is fixedly connected to the inward side of the limiting block 17, and the first limiting plate 18 is fixedly connected between the first spring column 19 and the limiting block 17.

[0039] Specifically, through the setting of the limiting block 17, when the cleaning plate 15 is inserted into the inner side of the fixing plate 13, the limiting block 17 can effectively play a limiting role, so that the cleaning plate 15 is limited and fixed inside the fixing plate 13.

[0040] Working principle: When in use, sleeved plate 11 is sleeved on the top of connecting block 10, and fixing bolt 12 is inserted through the interiors of connecting block 10 and sleeved plate 11, so as to realize the fixed connection between fixed plate 13 and fixing member 8. Then, through placing groove 14, cleaning plate 15 is inserted into the interior of fixed plate 13, so that first limiting plate 18 extends out from the top of fixed plate 13, enabling first limiting plate 18 to continuously brush the upper surface of filter plate 24, effectively ensuring the unobstructedness of filter plate 24 without clogging. During the process of inserting cleaning plate 15 into fixed plate 13, placing groove 14 will squeeze limiting block 17, causing limiting block 17 to push first limiting plate 18, and first limiting plate 18 to squeeze first spring column 19. When cleaning plate 15 is inserted into the appropriate position, first spring column 19 will reset, thereby pushing limiting block 17 to abut against the inner wall of placing groove 14, thus realizing the function of limiting and fixing. When disassembly is required, only by means of pull ring 16, cleaning plate 15 is lifted upwards, facilitating the quick disassembly between cleaning plate 15 and fixed plate 13. When mixing tank 2 is working, the vibration generated by mixing tank 2 will be transmitted to fixed base 20, and fixed base 20 will repeatedly and cyclically squeeze downwards. Under the characteristics of second spring column 22, fixed base 20 can effectively play a role in shock absorption and buffering.

[0041] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any perspective, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
