[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The utility model provides an embodiment: a sewage solid-liquid separation treatment device, including a support frame 1, one side of four support frames 1 is fixedly connected to the same tank body 3, a tank cover 4 is arranged on the top of the tank body 3, a servo motor 5 is fixedly connected to the middle of the top of the tank cover 4, the output end of the servo motor 5 passes through the tank cover 4 and is fixedly connected to a first rotating rod 6, the outer bottom of the first rotating rod 6 is rotatably connected to a hollow rod 8, the inner bottom of the hollow rod 8 is rotatably connected to a second rotating rod 11, the second rotating rod 11 and the first rotating rod The adjacent ends of the first rotating rod 6 are fixedly connected with a driving bevel gear 7, the inner right side of the hollow rod 8 is rotatably connected with a movable rod 9, the left end of the movable rod 9 is fixedly connected with a driven bevel gear 10, the two driving bevel gears 7 are respectively meshed with the upper and lower sides of the driven bevel gear 10, the outer side of the hollow rod 8 is rotatably connected with a ring 12, the top left side of the tank cover 4 is connected with a liquid inlet pipe 15, the outer sides of the first rotating rod 6 and the second rotating rod 11 are equidistantly fixedly connected with a plurality of stirring rods 14, and the inner side of the tank body 3 is provided with a cleaning mechanism 2;

[0032] Specifically, the servo motor 5 can drive the first rotating rod 6 to rotate clockwise. In this process, the active bevel gear 7 at the bottom of the first rotating rod 6 will also rotate synchronously. As the active bevel gear 7 rotates, the driven bevel gear 10 meshing with it also starts to rotate. This meshing transmission mode not only transmits power, but also ensures the stability and continuity of rotation. It is worth noting that the connecting rod 13 plays a key role in this process. It can limit the hollow rod 8 to prevent it from rotating with the rotation of the first rotating rod 6. This design cleverly achieves the fixation of the hollow rod 8, ensuring that the second rotating rod 11 can rotate counterclockwise stably. The counterclockwise rotation of the second rotating rod 11 causes the active bevel gear 7 thereon to rotate counterclockwise as well. At this time, since the stirring rods 14 on the first rotating rod 6 and the second rotating rod 11 rotate in opposite directions, they form a staggered rotating stirring effect inside the tank body 3. This stirring mode in opposite directions allows the flocculant and sewage in the tank body 3 to be mixed more fully, greatly improving the uniformity of mixing.

[0033] Reference Figure 2 and Figure 4The cleaning mechanism 2 includes a driving gear 201, which is fixedly connected to the middle and upper part of the outer side of the first rotating rod 6. The right end of the inner top of the tank cover 4 is rotatably connected to a movable shaft 202, and the outer side of the movable shaft 202 is fixedly connected to a driven gear 203, and the driven gear 203 is meshed with the driving gear 201. The inner top of the tank cover 4 is rotatably connected to a hollow gear ring 204, and the hollow gear ring 204 is meshed with the driven gear 203. A plurality of special-shaped scrapers 205 are fixedly connected around the bottom of the hollow gear ring 204, and the left and right sides of the ring 12 are fixedly connected to a connecting rod 13, and one end of the connecting rod 13 is fixedly connected to one side of the corresponding special-shaped scraper 205, and the sizes of the plurality of special-shaped scrapers 205 match the internal size of the tank body 3.

[0034] Specifically, when the first rotating rod 6 starts to rotate, the driving gear 201 on its outer side will rotate synchronously, and the driven gear 203 will also rotate synchronously. When the driven gear 203 rotates, the hollow gear ring 204 will also rotate. The rotation of the hollow gear ring 204 will eventually drive the rotation of the special-shaped scraper 205. The special-shaped scraper 205 is specially designed to scrape off the impurities remaining on the inner wall of the tank body 3. Its shape and material are carefully selected to ensure that various impurities on the inner wall of the tank body 3 can be effectively removed. As the special-shaped scraper 205 rotates, the impurities on the inner wall of the tank body 3 are gradually scraped off, thereby achieving the purpose of cleaning. This design makes it relatively simple for the staff to clean the inner wall of the tank body 3. They no longer need to scrape manually, which not only improves work efficiency but also reduces the labor intensity of the staff.

[0035] Reference Figure 1 and Figure 2 The bottom of the tank body 3 is connected with a liquid outlet 18, a filter screen 19 is arranged inside the liquid outlet 18, the liquid outlet 18 and the end away from the liquid inlet pipe 15 are both threadedly connected with a sealing cover 16, the top front side of the tank cover 4 is connected with a liquid inlet 17, the left and right sides of the liquid outlet 18 are both threadedly connected with a first bolt 20, one end of the first bolt 20 passes through the liquid outlet 18 and the filter screen 19 respectively;

[0036] Specifically, when sewage flows through the filter 19, the filter 19 can effectively intercept solid particles, while the liquid flows out smoothly through the filter 19 and enters the next treatment process. This process not only realizes the effective separation of solid and liquid, but also ensures the smooth progress of subsequent treatment steps. After all the liquid is discharged, the first bolt 20 is loosened to release the limit fixation of the filter 19. At this time, the solid impurities in the sewage can be collected and centrally treated, which can not only reduce the content of harmful substances in the sewage, but also prevent secondary pollution to the environment.

[0037] Reference Figure 1A controller 22 is fixedly connected to the left side of the tank body 3, and the controller 22 is electrically connected to the servo motor 5. A protective cover 23 is arranged on the outside of the controller 22, and one side of the protective cover 23 is rotatably connected to the left side of the tank body 3;

[0038] Specifically, the operation of the servo motor 5 can be controlled by the controller 22 , and the protective cover 23 can protect the controller 22 from being damaged by external factors.

[0039] Reference Figure 1 and Figure 2 The left and right sides of the tank cover 4 are both threadedly connected with a second bolt 21, and one end of the second bolt 21 passes through the tank cover 4 and the tank body 3 in sequence;

[0040] Specifically, loosening the second bolt 21 can release the position-limiting fixation of the tank cover 4, and then the tank cover 4 can be removed to inspect and maintain the structure at its bottom.

[0041] Working principle: when using the device, first inject the external sewage into the tank body 3 through the liquid inlet 17, then open the sealing cover 16 on the top of the liquid inlet pipe 15, inject the flocculant into the tank body 3 through the liquid inlet pipe 15, and then screw on the sealing cover 16. At this time, the servo motor 5 can drive the first rotating rod 6 to rotate clockwise, and the active bevel gear 7 at the bottom end of the first rotating rod 6 will rotate clockwise. At this time, the driven bevel gear 10 will also rotate due to the engagement with the active bevel gear 7. Since the connecting rod 13 can limit the hollow rod 8, it will not rotate with the rotation of the first rotating rod 6, so that the active bevel gear 7 on the second rotating rod 11 can be rotated counterclockwise, and the second rotating rod 11 will rotate counterclockwise. Since the stirring rods 14 on the first rotating rod 6 and the second rotating rod 11 rotate in opposite directions, the flocculant and sewage in the tank body 3 can be mixed more evenly, and the expected treatment can be achieved in a shorter time. The treatment effect can be achieved, thereby improving the subsequent sewage treatment efficiency and meeting the needs of users. When the first rotating rod 6 rotates, the driving gear 201 on its outer side will rotate accordingly, and the driven gear 203 will also rotate due to the meshing with it. At this time, the hollow gear ring 204 will also rotate due to the meshing with the driven gear 203, thereby driving the special-shaped scraper 205 to rotate to scrape off the impurities remaining on the inner wall of the tank body 3. It is relatively simple for the staff to clean the inner wall of the tank body 3, thereby improving the practicality of the device. After the mixing work is completed, the sealing cover 16 at the bottom of the liquid outlet 18 is unscrewed. At this time, the sewage can be separated into solid and liquid through the filter screen 19, and the liquid will flow out through the filter screen 19 to enter the next operation process. After all the liquid is discharged, loosening the first bolt 20 can release the limit fixation of the filter screen 19. At this time, the filter screen 19 can be removed to collect the solids in the sewage and then centrally treat it.
