DETAILED DESCRIPTION

[0023] 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.

[0024] Reference Figure 1-5 A sedimentation tank for treating sewage in a park, comprising a barrel body 1, both side walls of the barrel body 1 are fixedly connected with a water outlet pipe 101 and a sewage pipe 102, and the sewage pipe 102 extends to the bottom of the inner cavity of the barrel body 1, and also includes:

[0025] A top plate 2 is clamped on the top of the barrel body 1, a servo motor 201 is fixedly connected to the top of the top plate 2, a rotating shaft 202 is fixedly connected to the end of the servo motor 201 inside the barrel body 1, a sliding groove is provided in the inner cavity of the rotating shaft 202, a float 203 is slidably connected to the inner wall of the sliding groove, and both sides of the float 203 are fixedly connected to the collecting components;

[0026] The collecting assembly includes a collecting box 204, an elastic assembly and a pressing plate 205. The collecting box 204 is fixedly mounted on the side wall of the float 203, and a water inlet is provided on one side of the collecting box 204, and a filtering hole is provided on the other side. The inner wall of the collecting box 204 is fixedly connected to the elastic assembly, and the end of the elastic assembly is fixedly connected to the pressing plate 205.

[0027] The elastic component includes a sleeve 206, a sliding column 207 and a first spring 208. The sleeve 206 is fixedly mounted on the inner wall of the collection box 204. The inner wall of the sleeve 206 is slidably connected with the sliding column 207. The sliding column 207 is fixedly connected to the pressure plate 205. The first spring 208 is fixedly connected between the sliding column 207 and the sleeve 206.

[0028] It should be noted that: when sewage is passed into the inner cavity of the barrel body 1, under the action of the float 203, the collection box 204 will float on the surface of the sewage, and then the servo motor 201 is turned on, and the servo motor 201 drives the rotating shaft 202 to rotate, and the rotating shaft 202 drives the collection box 204 to rotate through the float 203. During the rotation of the collection box 204, the sewage will be applied, so that the pressure plate 205 drives the sliding column 207 to slide toward the inner cavity of the sleeve 206. At this time, the first spring 208 is squeezed to generate a rebound force, and the sewage on the inner cavity surface of the barrel body 1 will reach the inner cavity of the collection box 204 through the water inlet. As the collection box 204 rotates, the sewage will flow out from the filter hole on the other side of the collection box 204, and the impurities It will remain in the inner cavity of the collection box 204. After the rotating shaft 202 stops rotating after cleaning, under the action of the rebound force of the first spring 208, the pressure plate 205 follows the sliding column 207 to slide to the outside of the sleeve 206, so that the pressure plate 205 is stuck at the water inlet of the side wall of the collection box 204, resulting in the impurities collected in the inner cavity of the collection box 204 no longer flowing out into the sewage, thereby collecting impurities floating on the surface of the sewage, and the top plate 2 can be removed from the top of the barrel body 1, and the collection box 204 can be cleaned. After the impurities on the surface of the sewage are removed, the sewage can be settled, wherein the sludge impurities after the sewage is settled can be removed through the sewage pipe 102, and the water settled on the top can be discharged through the outlet pipe 101.

[0029] Reference Figure 1-5 , a material storage box 3 is fixedly connected to the top of the top plate 2, and a partition 301 is fixedly connected to the middle of the inner wall of the material storage box 3;

[0030] A sliding block 302 is slidably connected between the partition 301 and the storage box 3, a connecting column 303 is fixedly connected to the bottom of the sliding block 302, and the connecting column 303 extends to the inner cavity of the barrel body 1;

[0031] A second spring 304 is fixedly connected between the sliding block 302 and the storage box 3, a collision block 305 is fixedly connected to the bottom end of the connecting column 303, and a collision column 306 is fixedly connected to the side wall of the rotating shaft 202;

[0032] It should be noted that: when the rotating shaft 202 rotates, the collision column 306 on its side wall will collide with the collision block 305, thereby causing the collision block 305, the connecting column 303 and the sliding block 302 to slide in the inner cavity of the storage box 3, thereby increasing the pressure in the inner cavity of the storage box 3. At the same time, the second spring 304 is compressed to generate a rebound force, and the flocculant in the inner cavity of the storage box 3 is sprayed into the sewage in the inner cavity of the barrel body 1, so as to accelerate the precipitation of impurities in the sewage. After the collision column 306 moves away from the collision block 305, under the action of the rebound force of the second spring 304, the collision block 305 and the sliding block 302 will return to their original positions and wait for the next collision, thereby completing the orderly addition of the flocculant to the sewage in the inner cavity of the barrel body 1.

[0033] Reference Figure 1-5A feed pipe 307 is fixedly connected to the top of the storage box 3, and a discharge pipe 308 is fixedly connected to the bottom of the storage box 3, and the inner cavities of the feed pipe 307 and the discharge pipe 308 are both provided with a one-way valve;

[0034] The bottom of the barrel 1 is set to be conical, and the bottom of the collision block 305 is set to be arc-shaped;

[0035] It should be noted that: flocculant is added to the storage box 3 through the feed pipe 307, and the flocculant is discharged to the barrel body 1 through the discharge pipe 308. The setting of the one-way valve can make the discharge pipe 308 only discharge material, and the feed pipe 307 can only feed material and inhale air. The conical setting at the bottom of the barrel body 1 facilitates the sedimentation of sludge, and the setting of the collision block 305 facilitates that after the collision column 306 collides with the collision block 305, the collision block 305 can slide upward.

[0036] Operation method: Sewage is passed into the inner cavity of the barrel body 1. Under the action of the float 203, the collection box 204 will float on the surface of the sewage. Then, the servo motor 201 is turned on. The servo motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the collection box 204 to rotate through the float 203. During the rotation of the collection box 204, the pressure of the sewage is applied, so that the pressure plate 205 drives the sliding column 207 to slide toward the inner cavity of the sleeve 206. At this time, the first spring 208 is squeezed to generate a rebound force. The sewage on the inner cavity surface of the barrel body 1 will reach the inner cavity of the collection box 204 through the water inlet. The collecting box 204 rotates, and the sewage will flow out from the filter holes on the other side of the collecting box 204, while the impurities will remain in the inner cavity of the collecting box 204. After the cleaning is completed, the rotating shaft 202 stops rotating. Under the rebound force of the first spring 208, the pressing plate 205 follows the sliding column 207 to slide toward the outside of the sleeve 206, so that the pressing plate 205 is stuck at the water inlet of the side wall of the collecting box 204, resulting in the impurities collected in the inner cavity of the collecting box 204 no longer flowing out into the sewage. In this way, the impurities floating on the surface of the sewage can be collected, and the top plate 2 can be removed from the top of the barrel body 1 to clean the collecting box 204.

[0037] When the rotating shaft 202 rotates, the collision column 306 on its side wall will collide with the collision block 305, thereby causing the collision block 305, the connecting column 303 and the sliding block 302 to slide in the inner cavity of the storage box 3, thereby increasing the pressure in the inner cavity of the storage box 3. At the same time, the second spring 304 is compressed to generate a rebound force, and the flocculant in the inner cavity of the storage box 3 is sprayed into the sewage in the inner cavity of the barrel body 1, so as to accelerate the precipitation of impurities in the sewage. After the collision column 306 moves away from the collision block 305, under the action of the rebound force of the second spring 304, the collision block 305 and the sliding block 302 will return to their original positions and wait for the next collision, thereby completing the orderly addition of the flocculant to the sewage in the inner cavity of the barrel body 1, wherein the sludge impurities after the sewage is precipitated can be removed through the sewage discharge pipe 102, and the water precipitated on the top can be discharged through the outlet pipe 101.
