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

[0002] The existing publication number CN220788342U discloses a dosing device for sludge treatment and processing. This device heats the tank through a water bath heating device, which accelerates the hydrolysis rate of the agent and improves the sludge conditioning effect and efficiency. However, the dosing hopper of this device is fixed. When adding the agent into the tank, the agent falls into the tank from a fixed position. This will cause the agent to be unevenly distributed in the tank. There will be an excess of agent in some areas and an insufficient agent in other areas, which will make it difficult for some sludge to be effectively treated and affect the overall treatment effect. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a decentralized dosing device, which solves the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a decentralized dosing device, including a tank, a small opening at the top of the tank, and a rotating ring adapted to the small opening installed at the top of the tank. A driving mechanism for driving the rotating ring to rotate is provided on the side of the tank. A fixed frame is movably installed on one side of the top of the rotating ring. A fixing mechanism is provided between the fixed frame and the rotating ring, and a dispensing mechanism is provided at the end of the fixed frame.

[0005] The dispensing mechanism includes an equipment box fixedly installed at the end of a fixed frame. One end of the equipment box is connected to a drug inlet pipe, and the side of the drug inlet pipe facing away from the equipment box is connected to a drug delivery pipe. A branch pipe is connected to the bottom of the drug delivery pipe, and a diverter plate is fixedly installed inside the drug delivery pipe.

[0006] Furthermore, a fan is installed inside the equipment box, a filter screen is installed on the inner wall of the drug inlet pipe, and a drug dispensing hopper is installed at the upper end of the drug inlet pipe.

[0007] Furthermore, the fixing mechanism includes two uprights fixedly installed on the top of the rotating ring. The two uprights are symmetrically arranged on both sides of the fixing frame, and a pressure rod is slidably connected between the two uprights. Insert rods are symmetrically installed at the bottom of the pressure rods. Insert holes for inserting the insert rods are provided on both the fixing frame and the rotating ring.

[0008] Furthermore, a connecting spring is sleeved on the outside of the upright, and the upper and lower ends of the connecting spring are fixedly connected to the upper end of the upright and the top of the pressure rod, respectively.

[0020] 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.

[0021] The dosing hopper in existing sludge treatment dosing devices is fixed. When adding chemicals into the tank, the chemicals fall into the tank from a fixed position. This causes uneven distribution of the chemicals in the tank, resulting in some areas having excessive chemicals while others have insufficient chemicals. Consequently, some sludge cannot be effectively treated, affecting the overall treatment effect.

[0022] To address the deficiencies in the dosing process of the aforementioned dosing device, please refer to [link / reference needed]. Figures 1-4 The present invention provides a decentralized dosing device that can evenly sprinkle the powder onto the sludge, allowing it to mix thoroughly with the sludge and optimize the sludge treatment effect. The dosing device is based on a tank 1. A small opening 2 is provided at the top of the tank 1 to prevent sludge from overflowing during stirring. A rotating ring 3, adapted to the small opening 2, is installed at the top of the tank 1. A drive mechanism 4 is provided on the side of the tank 1 to rotate the rotating ring 3. A fixed frame 5 is movably mounted on one side of the top of the rotating ring 3. A dispensing mechanism 6 is provided at the end of the fixed frame 5. The dispensing mechanism 6 is used to add powder into the tank 1. The drive mechanism 4 drives the rotating ring 3 to rotate, and the rotation of the rotating ring 3 drives the dispensing mechanism 6 to rotate via the fixed frame 5. The dispensing mechanism 6 can achieve dispersed powder addition. The dispensing mechanism 6 includes an equipment box 61 fixedly installed at the end of the fixed frame 5. One end of the equipment box 61 is connected to an inlet pipe 62. The side of the inlet pipe 62 facing away from the equipment box 61 is connected to a delivery pipe 63. A branch pipe 64 is connected to the bottom of the delivery pipe 63. Internally, a diverter plate 65 is fixedly installed. A fan 67 is installed inside the equipment box 61. A filter screen 68 is installed on the inner wall of the inlet pipe 62, and a dosing hopper 66 is installed at the upper end of the inlet pipe 62. Powder is fed into the inlet pipe 62 from the dosing hopper 66. The fan 67 blows the powder falling into the inlet pipe 62 into the delivery pipe 63. Due to the diverter plate 65, the powder is divided into two parts, one of which enters the delivery pipe 63. The powder falls into the delivery pipe 63, delivering the powder to the outer ring of the sludge. Another portion of the powder enters the branch pipe 64 from below the diversion plate 65 and falls into the branch pipe 64, delivering the powder to the inner ring of the sludge. The delivery pipe 63 and the branch pipe 64 can deliver the powder into the tank 1 from two different points. With the rotation of the rotating ring 3, dispersed dosing can be performed, spreading the powder evenly on the sludge, which is beneficial for mixing the powder and the sludge and optimizes the equipment's treatment effect on the sludge.

[0023] To facilitate maintenance of the dispensing mechanism 6, a fixing mechanism 7 is provided between the fixing frame 5 and the rotating ring 3. The fixing mechanism 7 consists of two uprights 71 fixedly installed on the top of the rotating ring 3. The two uprights 71 are symmetrically arranged on both sides of the fixing frame 5, and a pressure rod 72 is slidably connected between the two uprights 71. Insert rods 73 are symmetrically installed at the bottom of the pressure rod 72. Insert holes for inserting the insert rods 73 are provided on both the fixing frame 5 and the rotating ring 3. A connecting spring 74 is sleeved on the outside of the uprights 71. The upper and lower ends of the connecting spring 74 are fixedly connected to the upper end of the uprights 71 and the top of the pressure rod 72, respectively. The insert rods 73 can enter the insertion holes through the elastic force of the connecting spring 74 to fix the fixing frame 5, thereby fixing the dispensing mechanism 6 on the rotating ring 3. When disassembling the dispensing mechanism 6, the pressure rod 72 is pulled to move the insert rods 73 out of the insertion holes, and then the fixing frame 5 and the dispensing mechanism 6 can be removed from the rotating ring 3.

[0024] To achieve the effect of rotating ring 3 driving the dispensing mechanism 6, the drive mechanism 4 includes a stand 41 fixedly installed on one side of the tank 1. A servo motor 42 is fixedly installed on the upper end of the stand 41. A gear 43 is fixedly connected to the output end of the servo motor 42. A gear 44 meshing with gear 43 is fixedly sleeved on the outside of the rotating ring 3. The drive servo motor 42 can drive gear 43 to rotate. The rotation of gear 43 can drive gear 44 to rotate. The rotation of gear 44 can drive the rotating ring 3 to rotate, thereby driving the dispensing pipe 63 and branch pipe 64 to rotate, and performing a decentralized dosing operation on the tank 1.

[0025] Reference Figure 1 As shown, a support 8 is installed at the bottom of the tank 1, and a stirring rod is installed inside the tank 1. A motor for driving the stirring rod is located at the center of the bottom of the tank 1. The support 8 can support the tank 1, and the driving motor can drive the stirring rod to stir and mix the sludge and the powder, thereby achieving the treatment of the sludge.
