Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a dosing device. Background Technology

[0002] In the field of wastewater treatment, large-scale wastewater treatment ponds are crucial facilities due to their large processing capacity. However, administering chemicals to large-scale wastewater treatment ponds presents numerous challenges.

[0003] Among these challenges, the large area and high capacity of wastewater treatment ponds present a particularly prominent problem in terms of chemical dispersion. Traditional dosing devices have limited dosing points, and after the chemical is injected, its distribution is difficult to achieve evenly across the entire pond in a short time due to the vast space and the limited range of the agitator. Even with auxiliary methods such as stirring, the large scale of the wastewater pond limits the effective range of the stirring equipment, making it impossible to create a sufficiently strong and uniform water flow. This results in chemical accumulation in localized areas, while the concentration in other areas remains insufficient. This uneven dispersion leads to inadequate contact and reaction between the chemical and pollutants in the wastewater.

[0004] Moreover, excessive use of chemicals in some areas leads to resource waste and increases wastewater treatment costs; while in areas where chemicals are not fully in contact, pollutants in the wastewater cannot be effectively degraded and removed, resulting in substandard effluent quality. How to achieve efficient dispersion of chemicals in large wastewater ponds has become a critical issue that urgently needs to be addressed. Utility Model Content

[0054] Example 1:

[0055] This embodiment provides a dosing device, which is installed on the sewage tank 1, such as... Figure 1 As shown, it includes: a moving component 2 and a stirring component 3; the moving component 2 is used to drive the stirring component 3 to move, and the stirring component 3 is used to add and disperse the agent;

[0056] like Figure 2 and Figure 4 As shown,

[0057] Mobile component 2 includes:

[0058] Rack 21;

[0059] Specifically, according to the shape of the sewage tank 1, a frame 21 is fixedly installed above the sewage tank 1 so that the frame 21 spans the sewage tank 1 so that subsequent dosing can be dispersed to various parts of the sewage tank 1; a sliding groove is formed on the inner side of the frame 21, and two sliding rods 23 are fixedly connected in the sliding groove. The sliding rods 23 are set to make the movable slider 24 more stable, and the number of sliding rods 23 can be increased or decreased according to actual needs;

[0060] The movable slider 24 is slidably connected to the frame 21.

[0061] Specifically, the movable slider 24 is located in the slide groove of the frame 21 and is slidably connected to the slide groove and the slide rod 23;

[0062] The drive unit is used to drive the movable slider 24 to slide on the frame 21;

[0063] like Figure 4 As shown, the drive unit includes:

[0064] The threaded screw 22 is rotatably connected to the frame 21, and the threaded screw 22 is threadedly connected to the movable slider 24.

[0065] Specifically, the threaded screw 22 is located in the slide groove of the frame 21. One end of it is rotatably connected to one side of the slide groove, and the other end passes through the inner wall of the frame 21 and is fixedly connected to the output shaft of the first motor 25. The part that passes through the inner wall of the frame 21 is rotatably connected to the frame 21, and the other end passes through the movable slider 24 and is threadedly connected to the movable slider 24.

[0066] The first motor 25 is mounted on the frame 21, and its output shaft is connected to the threaded screw 22 to drive the threaded screw 22 to rotate.

[0067] Specifically, the first motor 25 is fixedly connected to an outer wall of the frame 21. The first motor 25 can control the forward and reverse rotation of its output shaft via a limit switch. It can be understood that limit switches can be installed at the extreme positions of the sliding slider 24 on both sides. Specifically, two limit switches are installed on each side of the frame 21. When the first motor 25 is powered on, it starts and drives the sliding slider 24 to move through the threaded screw 22. When the sliding slider 24 moves to its extreme position and contacts the limit switch on that side, the limit switch will control the output shaft of the first motor 25 to rotate in the opposite direction, so that the sliding slider 24 moves back, thereby enabling the sliding slider 24 to perform reciprocating operation.

[0068] like Figure 3 As shown, the stirring assembly 3 includes:

[0069] The movable plate 31 is mounted on the movable slider 24 and slides together with the movable slider 24.

[0070] Specifically, the movable plate 31 is fixedly connected to the movable slider 24. In other embodiments, the movable plate 31 can be integrally formed with the movable slider 24.

[0071] Rotating rod 36, rotating rod 36 rotatably connected to the movable plate 31;

[0072] Specifically, the rotating rod 36 passes through the movable plate 31 and is rotatably connected to the movable plate 31, with its lower end extending to the inner side of the sewage tank 1;

[0073] A stirring plate 35 is provided on the rotating rod 36;

[0074] Specifically, a number of stirring plates 35 are fixedly connected to the part of the rotating rod 36 extending to the inner side of the sewage tank 1. The number of stirring plates 35 can be adjusted according to the actual situation, and no limit is made here. The rotation of the rotating rod 36 drives the stirring plates 35 to rotate, thereby stirring the sewage and chemicals in the sewage tank 1 so as to disperse the chemicals.

[0075] Liquid storage frame 33, a liquid storage frame 33 provided on the rotating rod 36, is used to store medicine;

[0076] Specifically, the liquid storage frame 33 is circular in shape, with a storage cavity for storing the medicine formed on the inside. The liquid storage frame 33 is fixedly connected to the rotating rod 36 and is located above the stirring plate 35.

[0077] The driving component is used to drive the rotating rod 36 to rotate.

[0078] like Figure 4 As shown, the driving component includes:

[0079] Rack 27, rack 27 mounted on frame 21;

[0080] Specifically, connecting blocks 26 are fixedly connected to both sides of the frame 21. The two connecting blocks 26 are fixedly connected to both sides of the rack 27 respectively. The length direction of the rack 27 is the same as the moving direction of the slider 24.

[0081] Gear 32 is mounted on the rotating rod 36. Gear 32 meshes with rack 27. When gear 32 translates, rack 27 pushes gear 32 to rotate, thereby causing rotating rod 36 to rotate.

[0082] Specifically, the upper end of the rotating rod 36 is fixedly connected to the gear 32, which is on the same axis as the rotating rod 36. When the moving slider 24 drives the rotating rod 36 to move, the rotating rod 36 drives the gear 32 to move. When the gear 32 moves, the rack 27 will drive the gear 32 to rotate, thereby causing the rotating rod 36 to rotate.

[0083] The leakage structure is used to allow the agent in the storage box 33 to leak into the sewage tank 1.

[0084] like Figure 3 As shown, the leakage structure includes: leakage holes 34. Several leakage holes 34 are provided on the liquid storage frame 33, and the agent in the liquid storage frame 33 leaks out from the leakage holes 34 into the sewage tank 1.

[0085] Specifically, several leakage holes 34 are provided on the bottom wall and side wall surrounding the liquid storage frame 33. The size and number of leakage holes 34 can be designed according to the actual situation so that the pharmaceutical department can leak into the sewage tank 1 through the leakage holes 34 at an appropriate time.

[0086] Working principle: When the first motor 25 is energized, the output shaft of the first motor 25 rotates, driving the threaded screw 22 to rotate. The rotation of the threaded screw 22 drives the movable slider 24 to move. The movement of the movable slider 24 drives the movable plate 31 to move. The movement of the movable plate 31 drives the rotating rod 36 to move. The movement of the rotating rod 36 drives the gear 32, the storage frame 33, and the stirring plate 35 to move. When the storage frame 33 moves, the medicine stored inside it will leak into the sewage tank 1 through the leakage hole 34 to achieve the purpose of dosing. When the gear 32 moves, the rack 27 will drive the gear 32 to rotate. The rotation of the gear 32 drives the rotating rod 36 to rotate. The rotation of the rotating rod 36 drives the stirring plate 35 and the storage frame 33 to rotate. The rotation of the stirring plate 35 will stir the sewage and medicine in the sewage tank 1 to promote the flow of sewage and medicine and to disperse the medicine. Moreover, the rotation of the storage frame 33 will use centrifugal force to throw the medicine out through the leakage hole 34, so that the medicine is dispersed to all parts of the sewage tank 1.

[0087] In summary, the rotation of the rotating rod 36 causes the stirring plate 35 fixed to its outer wall to rotate, stirring the sewage, breaking the static balance of water flow in the sewage tank 1, and promoting sewage flow. At the same time, the liquid storage frame 33 on the rotating rod 36 also rotates with the rotation of the rotating rod 36. During the rotation, the leakage holes 34 opened at the bottom of the liquid storage frame 33 and on the outer wall evenly drip the medicine into different positions in the sewage tank 1. In addition, the continuous movement and rotation of the rotating rod 36 and the stirring plate 35 continuously stir the sewage, promoting the diffusion of the medicine in the sewage tank 1, so that the medicine can be quickly and evenly mixed with the sewage, realizing comprehensive and efficient dosing of the large sewage tank 1. It effectively solves the problems of limited dosing points and slow natural diffusion of medicine in traditional dosing devices, greatly improves the dispersion uniformity of the medicine in the large sewage tank 1, and ensures that the medicine and pollutants in the sewage fully contact and react.

[0088] Example 2:

[0089] The difference between this embodiment and Embodiment 1 is that the driving component and driving unit are different.

[0090] like Figure 5 As shown, the driving component is a second motor 38, and the output shaft of the second motor 38 is connected to the rotating rod 36, thereby driving the rotating rod 36 to rotate.

[0091] Specifically, a bracket 37 is fixedly connected to the movable plate 31, and a second motor 38 is fixedly connected to the bracket 37; the output shaft of the second motor 38 is fixedly connected to the rotating rod 36.

[0092] The drive unit includes:

[0093] Rack 27, rack 27 mounted on frame 21;

[0094] Specifically, connecting blocks 26 are fixedly connected to both sides of the frame 21. The two connecting blocks 26 are fixedly connected to both sides of the rack 27 respectively. The length direction of the rack 27 is the same as the moving direction of the slider 24.

[0095] Gear 32 is mounted on the rotating rod 36. Gear 32 meshes with rack 27. When gear 32 rotates, it moves along the length of rack 27, thereby driving rotating rod 36 to move.

[0096] Specifically, the upper end of the rotating rod 36 is fixedly connected to the gear 32, which is on the same axis as the rotating rod 36. When the second motor 38 drives the rotating rod 36 to rotate, the rotating rod 36 drives the gear 32 to rotate. When the gear 32 rotates, it will move along the length of the rack 27, thereby driving the rotating rod 36 to move.

[0097] Working principle: When the second motor 38 is energized, the rotating rod 36 rotates. When the rotating rod 36 rotates, it drives the gear 32, the liquid storage frame 33, and the stirring plate 35 to rotate. The function of the rotating liquid storage frame 33 and the stirring plate 35 can be referred to the working principle of Embodiment 1, which will not be elaborated here. When the gear 32 rotates, it meshes with the rack 27. The gear 32 will move along the length direction of the rack 27, thereby driving the rotating rod 36 to move. The movement of the rotating rod will drive the moving plate 31 to move, and the moving plate 31 will drive the moving slider 24 to move.

[0103] At least one first connecting hole 39 is provided on the rotating rod 36; the first connecting hole 39 connects the inner side of the liquid storage frame 33 with the rod cavity 310.

[0104] Specifically, the number of first connecting holes 39 can be adjusted according to the actual situation, and is not limited here. The first connecting holes 39 are located at the bottom inside the liquid storage frame 33 so that the medicine in the liquid storage frame 33 can flow fully into the rod cavity 310.

[0105] The inner cavity 312 is formed on the inner side of the stirring plate 35;

[0106] Specifically, the side of the inner cavity 312 away from the rotating rod 36 is a sealed structure, while the side closer to the rotating rod 36 is an open structure;

[0107] Holes 313: Several holes 313 are provided on the stirring plate 35, which allow the inner cavity 312 to communicate with the outside.

[0108] Specifically, the number of holes 313 can be adjusted according to the actual situation, and is not limited here. Several holes 313 are evenly distributed along the length of the stirring plate 35.

[0109] The rotating rod 36 has a number of second connecting holes 311 corresponding to the stirring plate 35. The second connecting holes 311 connect the inner cavity 312 and the rod cavity 310.

[0110] Working principle: The agent in the storage frame 33 passes through the first connecting hole 39, the rod cavity 310, the second connecting hole 311, and the inner cavity 312 in sequence, and then leaks into the sewage tank 1 through the hole 313.

[0111] Example 4:

[0112] This embodiment is based on Embodiment 1 or Embodiment 2, with the added part being the leakage structure of Embodiment 3; specifically, this embodiment further includes the following based on the leakage structure of Embodiment 1 or Embodiment 2:

[0114] At least one first connecting hole 39 is provided on the rotating rod 36; the first connecting hole 39 connects the inner side of the liquid storage frame 33 with the rod cavity 310.
