DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a sedimentation structure for sewage treatment described in an embodiment of the utility model comprises a sedimentation tank 8; a first support rod 81 is fixedly connected to the top of the sedimentation tank 8; a motor 82 is fixedly connected to the middle of the first support rod 81; a stirring rod 83 is fixedly connected to the output end of the motor 82; the middle of the stirring rod 83 passes through the middle of the first support rod 81; two stirring fan blades 84 are fixedly connected to the end of the stirring rod 83; two second support rods 1 are fixedly connected to the middle of the stirring rod 83; the two second support rods 1 are arranged oppositely; a sleeve 10 is fixedly connected to the end of the second support rod 1; a medicine rod 11 is slidably connected to the middle of the sleeve 10; a medicine storage tank 12 is provided on the top of the medicine rod 11; a first limit block 13 is fixedly connected to the top of the medicine rod 11; A second limiting block 14 is fixedly connected to the middle of the medicine rod 11; the second limiting block 14 is fixedly connected to the bottom of the sleeve 10; a plurality of groups of medicine outlet holes 15 are opened in the middle of the medicine rod 11; the plurality of groups of medicine outlet holes 15 are opened near the bottom of the medicine rod 11; a suspension block 16 is fixedly connected to the side wall of the medicine rod 11; a stirring plate 17 is fixedly connected to the side wall of the medicine rod 11; the stirring plate 17 and the suspension block 16 are arranged opposite to each other; a connecting block 18 is fixedly connected to the ends of the two stirring plates 17; when working, the sewage flows into the sedimentation tank 8 through the water inlet pipe. When the sewage enters the sedimentation tank 8, the two suspension blocks 16 bring the two medicine rods 11 up to suspend upward, and the medicine rod 11 is limited by the second limiting block 14, so that the second limiting block 14 and the sleeve 1 0 After contact, the medicine rod 11 stops moving, and the precipitation agent is put into the medicine storage tank 12. The precipitation agent enters the medicine rod 11 for storage. The motor 82 is powered on and turned on to rotate the stirring rod 83. The stirring blades 84 are driven by the rotation to stir the sewage. When the stirring rod 83 rotates, the two second support rods 1 rotate at the same time. When the second support rod 1 rotates, the medicine rod 11 rotates in the middle of the sewage.

The outflow amount of the precipitating agent can be effectively adjusted through the sponge block 53, so that the precipitating agent flows out according to the predetermined amount, which can effectively make the precipitating agent more uniform inside the sewage, and can effectively increase the reaction of the precipitating agent with the suspended matter and impurities in the sewage, thereby accelerating the sedimentation process, effectively reducing the time of sewage treatment, and effectively improving the efficiency of sewage treatment.
[0029] like Figure 2 and Figure 5 As shown, a connecting rope 6 is fixedly connected to the end of the slide plate 21; a gravity block 61 is fixedly connected to the end of the connecting rope 6; during operation, when the slide plate 21 slides outside the stirring plate 17 through the water flow, the gravity block 61 is moved by the flow of water, and when the gravity block 61 moves, the slide plate 21 is driven to slide by the connecting rope 6, and the gravity block 61 can make the slide plate 21 smoother during sliding, effectively reducing the resistance of the water flow pressure to the slide plate 21, and using the gravity block 61 as a power source can effectively save energy, and the operation is relatively simple and convenient, and different weights of gravity blocks 61 can be flexibly adapted to different sliding distances and speeds, and effectively increase the safety of work, and the maintenance cost is low.
[0030] like Figure 5As shown, a rubber pad 7 is installed on the side wall of the universal wheel 41; the rubber pad 7 is fixedly connected to the side wall of the universal wheel 41; during operation, when the universal wheel 41 contacts the bottom of the sedimentation tank 8, it rotates through the rotation direction of the stirring plate 17, and the universal wheel 41 contacts and rotates with the bottom of the sedimentation tank 8 through the rubber pad 7. The friction generated when the universal wheel 41 contacts the bottom of the sedimentation tank 8 can be effectively reduced through the rubber pad 7, and the wear of the universal wheel 41 caused by the friction of the universal wheel 41 on the sedimentation tank 8 can be effectively reduced, and the grip of the universal wheel 41 after contacting the sedimentation tank 8 can be effectively increased. The service life of the universal wheel 41 can be effectively increased through the rubber pad 7.
[0031] During operation, the sewage flows into the sedimentation tank 8 through the water inlet pipe. When the sewage enters the sedimentation tank 8, the two suspension blocks 16 lift the two medicine rods 11 to suspend upward, and the medicine rod 11 is limited by the second limit block 14. After the second limit block 14 contacts the sleeve 10, the medicine rod 11 stops moving, and the precipitation agent is put into the medicine storage tank 12. The precipitation agent enters the medicine rod 11 for storage, and the motor 82 is powered on and turned on to rotate the stirring rod 83. The stirring blades 84 are driven by the rotation to stir the sewage. When the stirring rod 83 rotates, the two second support rods 1 rotate at the same time. When the second support rod 1 rotates, the medicine rod 11 rotates in the middle of the sewage. During the rotation of the second support rod 1, the water flow generates an impact force to move the medicine rod 11 downward, and the top of the medicine rod 11 is limited by the medicine storage tank 12. The water flow brings the precipitated medicine inside the medicine rod 11 out from the medicine outlet 15 into the sewage, and then the sewage is stirred by the two stirring plates 17. When the sewage is precipitated, the motor 82 is turned off and the rotation is stopped. After stopping the rotation, the medicine rod 11 is moved upward again through the suspension block 16 without being subjected to the water flow pressure, so that the two stirring plates 17 are away from the precipitated sediment, and then the sediment is discharged. When the stirring plates 17 enter During the rotation, the slide plate 21 impacted by the water flow slides in the middle of the stirring plate 17, and the sediment deposited on the surface of the stirring plate 17 is cleaned by the slide plate 21. During the sliding of the slide plate 21, the spring 2 is used to stretch the slide plate 21, and the spring 2 is used to elastically reset the slide plate 21 after the slide. When the slide plate 21 slides in the middle of the stirring plate 17, the end of the fixed plate 3 is attached to the surface of the stirring plate 17 and moves on the surface of the stirring plate 17 at the same time, and the surface of the stirring plate 17 is cleaned by the fixed plate 3. When the medicine rod 11 moves downward, the stirring plate 17 moves upward at the same time. The stirring plate 17 is moved downward, and the stirring plate 17 is brought into contact with the bottom of the sedimentation tank 8 or the sediment through the universal wheel 41. After the precipitating agent is placed inside the medicine rod 11, the support plate 52 is slid, and the sponge block 53 is slid to the position corresponding to the medicine outlet hole 15. The middle of the position corresponding to the medicine outlet hole 15 is blocked by the sponge block 53. When the slide plate 21 slides on the outside of the stirring plate 17 through the water flow, the gravity block 61 is moved by the flow of water. When the gravity block 61 moves, the slide plate 21 is driven to slide through the connecting rope 6. When the universal wheel 41 contacts the bottom of the sedimentation tank 8, it rotates in the direction of rotation of the stirring plate 17.
