[0071] Please refer to Figures 1 to 6 The utility model discloses a domestic sewage sedimentation treatment device, which comprises a rotating shaft 0001, N first blades 0002 and N second blades 0003, wherein N is an integer greater than or equal to 1.

[0072] The N first blades 0002 and the N second blades 0003 are arranged on the surface of the rotating shaft 0001, and when N is greater than 1, one first blade 0002 is arranged between two adjacent second blades 0003 or one second blade 0003 is arranged between two adjacent first blades 0002.

[0074] The sawteeth of the first blade 0002 and the sawteeth of the second blade 0003 are distributed in a staggered manner.

[0075] It should be noted that: the domestic sewage sedimentation treatment device comprises a rotating shaft 0001, at least one first blade 0002 and at least one second blade 0003, in this embodiment, two first blades 0002 and two second blades 0003 are installed on the surface of the rotating shaft 0001, so that the first blade 0002 and the second blade 0003 have the function of rotation, wherein the included angle formed between the adjacent first blade 0002 and the second blade 0003 is 90°, which ensures that the blades can be uniformly distributed on the surface of the rotating shaft 0001, and ensures that the blades do not interfere with each other.

[0076] The rotating shaft 0001 is used for rotation, and drives the first blade 0002 and the second blade 0003 to rotate around the rotating shaft 0001, repeatedly scratches the inner wall to be cleaned, and cleans the sludge or moss on the inner wall.

[0077] The gap between the first sawtooth cleaning mechanism 0021 is provided for water flow, thereby reducing the resistance of the first blade 0002 rotating in water, and similarly, the gap between the teeth of the second sawtooth cleaning mechanism 0031 can be provided for water flow, thereby reducing the resistance of the second blade 0003 rotating in water, and improving the rotating speed of the first blade 0002 and the second blade 0003 in water. The sawteeth of the first blade 0002 and the sawteeth of the second blade 0003 are distributed in a staggered manner, which not only reduces the resistance of the first blade 0002 and the second blade 0003 in water, but also the first blade 0002 and the second blade 0003 clean the interval position of the arc surface on the same axial direction of the secondary sedimentation tank wall in turn, that is, the first blade 0002 cleans half of the area, and the second blade 0003 scratches the other half of the area cleaned by the first blade 0002, at the same time, the first sawtooth cleaning structure 0031 and the second sawtooth cleaning structure push the local water flow, thereby flushing the secondary sedimentation tank wall after being scratched, and further improving the cleaning effect.

[0078] The sleeve 0011 is used for orderly fixing the first blade 0002 and the second blade 0003, and simultaneously transmitting the rotating power to the first blade 0002 and the second blade 0003.

[0079] The connecting main shaft 0012 is used for connecting the sleeve 0011 with a device for providing rotating power, so as to transmit power to the sleeve 0011, so that the sleeve 0011 can drive the first blade 0002 and the second blade 0003 to rotate circumferentially along the wall of the secondary sedimentation tank, so that the scraper can clean the inner wall of the secondary sedimentation tank.

[0080] The beneficial effects of the embodiment are as follows:

[0081] When the scraper is rotated under force, the serrated blade on the first blade 0002 scrapes the inner wall of the secondary sedimentation tank to clean the algae or sludge on the inner wall, the second blade 0003 scrapes the inner wall of the secondary sedimentation tank to clean the algae on the inner wall, and the first blade 0002 and the second blade 0003 clean the interval positions of the arc surface on the same axial direction of the wall of the secondary sedimentation tank in turn, that is, the first blade 0002 cleans half of the area, and the second blade 0003 scrapes the other half of the area cleaned by the first blade 0002. The whole cleaning process is efficient and convenient, and the cleaning efficiency and efficiency of the inner wall of the secondary sedimentation tank are improved.

Secondly, the first brush 0212 and the first cleaning blade 0211 are detachably installed at the corresponding positions, which is conducive to timely replacement of new brushes or blades when the first brush 0212 or the first cleaning blade 0211 is worn out, so as to ensure the cleaning effect.

[0083] The second brush 0312 and the second cleaning blade 0311 are alternately arranged and distributed at the serration of the second blade 0003; the second cleaning blade 0311 scrapes the inner wall of the secondary sedimentation tank to clean the algae on the inner wall, and the second brush 0312 sweeps the position cleaned by the second cleaning blade 0311 on another second blade 0003, thereby cleaning the inner wall by hard contact and soft contact in turn, so that the cleaning is more thorough and the cleaning effect is effectively improved. Secondly, the second brush 0312 and the second cleaning blade 0311 are detachably installed at the corresponding positions, which is conducive to timely replacement of new brushes or blades when the second brush 0312 or the second cleaning blade 0311 is worn out, so as to ensure the cleaning effect.

[0084] It is worth noting that the first brush 0212 and the first cleaning blade 0211 on the two adjacent first blades 0002 are staggered, that is, at the same horizontal plane, the first cleaning blade 0211 is arranged at the same serration of one first blade 0002, and the first brush 0212 is arranged at the same serration of the other first blade 0002, that is, after the first cleaning blade 0211 of one first blade 0002 cleans the inner wall, the first brush 0212 of the other first blade 0002 cleans the position cleaned by the first cleaning blade 0211 of the first blade 0002 again, so as to avoid that the first cleaning blade 0211 cannot be cleaned completely, and the first brush 0212 can increase the contact area with the inner wall of the secondary sedimentation tank during cleaning, so as to more effectively remove the algae or sludge on the inner wall of the secondary sedimentation tank. Similarly, the second brush 0312 and the second cleaning blade 0311 on the two adjacent second blades 0003 are staggered, that is, at the same horizontal plane, the second cleaning blade 0311 is arranged at the same serration of one second blade 0003, and the second brush 0312 is arranged at the same serration of the other second blade 0003, that is, after the second cleaning blade 0311 of one second blade 0003 cleans the inner wall, the second brush 0312 of the other second blade 0003 cleans the position cleaned by the second cleaning blade 0311 of the second blade 0003 again, so as to avoid that the second cleaning blade 0311 cannot be cleaned completely, and the second brush 0312 can increase the contact area with the inner wall of the secondary sedimentation tank during cleaning, so as to more effectively remove the algae or sludge on the inner wall of the secondary sedimentation tank.

[0085] Specifically, in order to ensure that the first blade 0002 and the second blade 0003 can be fixed on the sleeve 0011, the sleeve 0011 has a plurality of first installation grooves 0111 and second installation grooves 0112, and the first installation grooves 0111 and the second installation grooves are arranged alternately; the first blade 0002 is installed in the first installation groove 0111, and the second blade 0003 is installed in the second installation groove 0112. The first blade 0002 is installed in the first installation groove 0111, and when the first blade 0002 cleans the inner wall, the inner wall of the first installation groove 0111 will have a supporting force on the root of the first blade 0002 installed in the first installation groove 0111, so as to offset the force of the inner wall on the first blade 0002 and reduce the falling of the first blade 0002 during cleaning. Similarly, the second blade 0003 is installed in the second installation groove 0112, and when the second blade 0003 cleans the inner wall, the inner wall of the second installation groove 0112 will have a supporting force on the root of the second blade 0003 installed in the second installation groove 0112, so as to offset the force of the inner wall on the second blade 0003 and reduce the falling of the second blade 0003 during cleaning.

[0086] It is worth noting that the upper end face of the sleeve 0011 is provided with a plurality of upper threaded holes, and the plurality of threaded holes are correspondingly distributed at the positions of the first mounting groove 0111 and the second mounting groove 0112; the lower end face of the sleeve 0011 is provided with a plurality of lower threaded holes, and the plurality of threaded holes are correspondingly distributed at the positions of the first mounting groove 0111 and the second mounting groove 0112. In this embodiment, the upper end face of the sleeve 0011 is provided with four upper threaded holes, and the lower end face of the sleeve 0011 is also provided with four lower threaded holes. The upper threaded hole and the lower threaded hole correspondingly distributed in one mounting groove form a group, and one group of threaded holes fixes the corresponding blade in the mounting groove from the upper and lower ends, and the threaded hole is used to install the blade, which is beneficial to speed up the replacement speed when the blade is worn out.

[0087] Specifically, in order to ensure that the scraper can rotate in the secondary sedimentation tank and have enough power to clean the secondary sedimentation tank, a power assembly 0004 is arranged above the rotating shaft 0001, and the power assembly 0004 comprises: a driving motor 0041; the output end of the driving motor 0041 is connected with a connecting main shaft 0012, and the connecting main shaft 0012 is driven to rotate by the driving motor 0041, so as to drive the whole rotating shaft 0001 to rotate. The output end of the driving motor 0041 is connected with the rotating shaft 0001, when the output end of the driving motor 0041 rotates, the rotating shaft 0001 is driven to rotate, and then the scraper is driven to rotate, so that the scraper can clean the inner wall of the secondary sedimentation tank in a large range.

[0088] Specifically, in order to reduce the resistance of the first blade 0002 and the second blade 0003 in water, the blade body of the first blade 0002 extends outward to form a first guide plate 0213, and the blade body of the second blade 0003 extends outward to form a second guide plate 0313. The first guide plate 0213 and the second guide plate 0313 enable the water flow to flow more smoothly along the plate surface, rather than directly impacting the plate surface. In this way, the impact force of the water flow on the first blade 0002 and the second blade 0003 can be reduced, thereby reducing the resistance.

[0089] Specifically, the first guide plate 0213 comprises a first inclined surface 2131 and a second inclined surface 2132, the first inclined surface 2131 faces upward, and the second inclined surface 2132 faces downward; the included angle between the first inclined surface 2131 and the first blade 0002 is α1, the included angle between the second inclined surface 2132 and the first blade 0002 is α2, and the constraint relationship between α1 and α2 is α1 < α2. That is, the first guide plate 0213 is placed at an appropriate angle, so that the water flow can flow more smoothly along the plate surface, rather than directly impacting the plate surface, and the impact force of the water flow on the plate can be reduced, thereby reducing the resistance.

[0090] Specifically, the second guide plate 0313 includes a third inclined surface 3131 and a fourth inclined surface 3132, the third inclined surface 3131 faces downward, and the fourth inclined surface 3132 faces upward; the third inclined surface 3131 forms an angle β1 with the second blade 0003, the fourth inclined surface 3132 forms an angle β2 with the first blade 0002, and the constraint relationship between β1 and β2 is β1>β2. That is, the second guide plate 0313 is placed at an appropriate angle, so that the water flow can flow more smoothly along the surface of the plate, rather than directly impacting the surface of the plate, which can reduce the impact force of the water flow on the plate, thereby reducing the resistance.

[0091] In the present embodiment, during the cleaning process, the scraper needs to be flushed in time, and during the flushing process, the water flow is divided from the first guide plate 0213, part of which flows along the first inclined surface 2131, then passes through the second guide plate 0313, and continues to be divided on the second guide plate 0313, part of which flows along the third inclined surface 3131, and the other part flows along the fourth inclined surface 3132, so as to guide the water flow to flow along a specific path, thereby reducing the resistance. Similarly, the water flow flowing along the second inclined surface 2132 will also flow along a specific path, thereby reducing the resistance.

[0092] It should be noted that the material of the first blade 0002 is metal, and the material of the second blade 0003 is metal. Preferably, the materials of the first blade 0002 and the second blade 0003 are stainless steel or aluminum alloy.
