Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sedimentation tank for wastewater treatment. Background Technology
[0002] Wastewater sedimentation tanks are an important component of wastewater treatment systems, primarily used to remove suspended solid particles from wastewater through gravity settling. Based on their location and function in the treatment process, wastewater sedimentation tanks can be classified into different types, such as primary sedimentation tanks, secondary sedimentation tanks, and chemical sedimentation tanks.
[0003] Chemical sedimentation tanks are used to remove specific pollutants through chemical reactions, such as phosphorus removal. In this type of sedimentation tank, chemical agents must be added, commonly including ferrous salts (such as ferrous sulfate) and aluminum salts (such as aluminum sulfate). These chemicals react with phosphate ions in the wastewater to form insoluble precipitates, which are then removed from the wastewater through the sedimentation process. However, existing treatment agents are mostly added in a single, all-inclusive manner, which can easily lead to agent accumulation and affect the treatment effect on pollutants in the wastewater. Therefore, we propose a sedimentation tank for wastewater treatment. Utility Model Content
[0004] The purpose of this invention is to provide a sedimentation tank for wastewater treatment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sedimentation tank for wastewater treatment, comprising a sedimentation tank body, a top plate fixedly installed on the top of the sedimentation tank body, two sets of fixed frames fixedly installed on the top of the top plate, a holding frame for carrying treatment agents slidably connected to the top of the fixed frames, a moving mechanism for driving the holding frame to move on the holding frame, a spreading mechanism for spreading the treatment agents over a large area below the holding frame, and a dispensing mechanism for causing the treatment agents to fall in batches inside the holding frame.
[0006] Furthermore, the material dispensing mechanism includes a guide seat, a first drive motor, a dispensing cylinder, and a holding slot. Guide seats are fixedly installed on both sides of the inner wall of the holding frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5 This utility model provides a technical solution: a sedimentation tank for wastewater treatment, including a sedimentation tank body 1, a top plate 2 fixedly installed on the top of the sedimentation tank body 1, two sets of fixing frames 3 fixedly installed on the top of the top plate 2, a holding frame 4 for carrying treatment agents slidably connected to the top of the fixing frame 3, a moving mechanism 5 for driving the holding frame 4 to move on the holding frame 4, a spreading mechanism 7 for spreading the treatment agents over a large area below the holding frame 4, and a dispensing mechanism 6 for causing the treatment agents to fall in batches inside the holding frame 4.
[0020] The wastewater to be treated is placed inside the sedimentation tank body 1, and the treatment agent is placed inside the holding frame 4. The moving mechanism 5 can move the holding frame 4 along the top of the sedimentation tank body 1, and the distributing mechanism 6 uses the chemical agent to be added in batches to fall above the spreading mechanism 7. Then the spreading mechanism 7 rotates, and the centrifugal force generated by the rotation sprays the chemical agent, which can increase the spreading area of the chemical agent, so that the wastewater inside the sedimentation tank body 1 can fully contact the chemical agent.
[0021] Please see Figure 1 and Figure 2The material distribution mechanism 6 includes a guide seat 8, a first drive motor 9, a material distribution cylinder 10, and a holding groove 11. Guide seats 8 are fixedly installed on both sides of the inner wall of the holding frame 4. The top of the guide seat 8 is arc-shaped. The material distribution cylinder 10, which is in contact with the inner wall of the guide seat 8, is rotatably connected inside the holding frame 4. The material distribution cylinder 10 is provided with a holding groove 11. The first drive motor 9 is fixedly installed on one side of the holding frame 4. The output end of the first drive motor 9 is fixedly connected to the material distribution cylinder 10.
[0022] The treatment agent to be sprayed is placed inside the holding frame 4. Then, the first drive motor 9 drives the distributing cylinder 10 to rotate, so that the treatment agent can be filled into the holding tank 11. Then, as the distributing cylinder 10 continues to rotate, the chemical agent placed inside the holding tank 11 can fall in batches. The guide seat 8 with the top set as arc can facilitate the treatment agent to fall into the holding tank 11.
[0023] Please see Figure 1 and Figure 3 The moving mechanism 5 includes a slide rail 12, a gear rack 13, a slider 14, a connecting frame 15, a second drive motor 16, and a first gear disk 17. The top of the fixed frame 3 is fixedly attached to the slide rail 12, and the slider 14 is slidably connected to the slide rail 12. The slider 14 is fixedly connected to the holding frame 4 through the connecting frame 15. The bottom of one set of fixed frames 3 is fixedly connected to the gear rack 13. The second drive motor 16 is fixedly installed on the holding frame 4, and the output end of the second drive motor 16 is fixedly connected to the first gear disk 17 that meshes with the gear rack 13.
[0024] When it is necessary to move the holding frame 4, the second drive motor 16 operates, and the second drive motor 16 drives the first gear disk 17 to rotate, so that the first gear disk 17 can move along the gear rack 13 that meshes with it, so that the holding frame 4 and the slider 14 can move along the slide rail 12, so that the holding frame 4 can move along the top of the sedimentation tank body 1 to spread chemical agents.
[0025] Please see Figure 1 , Figure 4 and Figure 5The spreading mechanism 7 includes a mounting base 18, a fixed shaft 19, a fixed disk 20, a spreading disk 21, a third drive motor 24, and a third gear disk 25. The mounting base 18 is fixedly installed at the bottom of the inner wall of the holding frame 4. The bottom of the mounting base 18 is fixedly connected to the fixed disk 20 through the fixed shaft 19. The spreading disk 21 is rotatably connected to the outside of the fixed shaft 19. A second gear disk 23 is fixedly installed at the bottom of the spreading disk 21. The third drive motor 24 is fixedly installed at the bottom of the fixed disk 20. The output end of the third drive motor 24 is fixedly connected to the third gear disk 25, which meshes with the second gear disk 23. Multiple sets of drive claws 22 with a "U" shaped cross section are fixedly installed at the top of the spreading disk 21.
[0026] The treatment agent, which falls in batches, lands on the spreading disc 21. Then, the third drive motor 24 drives the third gear disc 25 to rotate. The rotating third gear disc 25 can drive the second gear disc 23 and the spreading disc 21 to rotate. In this way, the treatment agent can be spread over a large area using the rotating spreading disc 21 and the drive claw 22.
[0027] Please see Figure 1 and Figure 5 The top of the spreading disc 21 is covered with a cushioning pad made of rubber material. The cushioning pad on the spreading disc 21 can prevent the spreading disc 21 from deforming due to a large amount of treatment agent falling.
[0028] In operation, firstly, the wastewater to be treated is placed inside the sedimentation tank body 1. Then, the treatment agent is placed inside the holding frame 4. The moving mechanism 5 then moves the holding frame 4 along the top of the sedimentation tank body 1, and the distributing mechanism 6 distributes the required chemical agent in batches above the spreading mechanism 7. The spreading mechanism 7 then rotates, using centrifugal force to spray the chemical agent, thus increasing the spreading area and ensuring the wastewater inside the sedimentation tank body 1 fully contacts the chemical agent. The treatment agent to be spread is placed inside the holding frame 4. Then, the first drive motor 9 drives the distributing cylinder 10 to rotate, filling the holding tank 11 with the treatment agent. As the distributing cylinder 10 continues to rotate, the chemical agent placed inside the holding tank 11 is further distributed. The chemical reagents are dropped in batches, and the arc-shaped guide seat 8 at the top facilitates the dropping of the reagents into the holding tank 11. When it is necessary to move the holding frame 4, the second drive motor 16 operates, driving the first gear disk 17 to rotate. This allows the first gear disk 17 to move along the gear rack 13 it meshes with, thus allowing the holding frame 4 and the slider 14 to move along the slide rail 12. This allows the holding frame 4 to move along the top of the sedimentation tank body 1 to spread the chemical reagents. The batches of treatment reagents fall onto the spreading plate 21. Subsequently, the third drive motor 24 drives the third gear disk 25 to rotate, and the rotating third gear disk 25 drives the second gear disk 23 and the spreading plate 21 to rotate. This allows the rotating spreading plate 21 and the drive claw 22 to spread the treatment reagents over a large area.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
