Description

Technical Field

[0001] This utility model relates to the field of chemical dosing devices, and in particular to a chemical dosing device for sludge dewatering treatment. Background Technology

[0002] Sludge contains a large amount of water, and its particle surface usually carries a negative charge, which repels each other, making it difficult to remove water. The dosing device can add flocculants and other agents to the sludge to neutralize the charge on the surface of the sludge particles, causing the particles to aggregate into larger flocs, thereby improving the dewatering performance of the sludge and making it easier for the water in the sludge to be separated under mechanical action.

[0003] In existing dosing devices, drugs can usually only be added to the treatment device in one direction, which may result in uneven distribution of drugs in the sludge, preventing the sludge from reacting fully with the drugs, leading to poor sludge dewatering, failure to achieve the expected treatment goals, and reduced treatment efficiency.

[0004] In response to the technical problem of difficulty in adding drugs in different directions, this application proposes a dosing device for sludge dewatering treatment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that make it difficult to add chemicals in different directions. This invention proposes a chemical dosing device for sludge dewatering treatment. By starting motor two, the connecting rod rotates left and right, causing the dosing frame to move repeatedly left and right, allowing chemicals to be added to different positions within the treatment device. This ensures the chemicals are evenly distributed throughout the device, facilitating a full reaction between the sludge and the chemicals, preventing poor sludge dewatering, ensuring the desired treatment goals are achieved, and improving treatment efficiency.

[0010] Furthermore, a connecting frame is fixedly connected to the front end of the adding frame, a connecting block is slidably connected to the inner wall of the connecting frame, and the inner wall of the connecting block is rotatably connected to the rear end of the connecting rod.

[0011] Furthermore, a folded tube is fixedly connected to the bottom end of the solenoid valve, and the bottom end of the folded tube is fixedly connected to the top end of the adding frame.

[0012] Furthermore, the stirring assembly includes a gear fixedly connected to a drive end of the motor, and gear rings are meshed on both sides of the outer wall of the gear, and the outer walls of the gear rings are rotatably connected to both sides of the inner wall of the outer shell.

[0026] 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.

[0027] Reference Figures 2-4 As shown, one embodiment of this utility model provides a dosing device for sludge dewatering treatment, including a shell 1. A second motor 11 is fixedly connected to the inner wall of the shell 1. The drive end of the second motor 11 is connected to an adding frame 10. A feed inlet 2 is fixedly connected to the left side of the inner wall of the shell 1. A solenoid valve 8 is fixedly connected to the inner wall of the shell 1. The outer wall of the adding frame 10 is slidably connected to the inner wall of the shell 1. Multiple nozzles are fixedly connected to the bottom end of the adding frame 10. A connecting rod 14 is rotatably connected to the inner wall of the shell 1. The inner wall of the connecting rod 14 has a sliding opening. The inner wall of the groove 15 is slidably connected to a slider 13. The drive end of the motor 11 is fixedly connected to a transmission rod 12. The bottom end of the transmission rod 12 is rotatably connected to the top end of the slider 13. The front end of the adding frame 10 is fixedly connected to a connecting frame 17. The inner wall of the connecting frame 17 is slidably connected to a connecting block 16. The inner wall of the connecting block 16 is rotatably connected to the rear end of the connecting rod 14. The bottom end of the solenoid valve 8 is fixedly connected to a folded tube 9. The bottom end of the folded tube 9 is fixedly connected to the top end of the adding frame 10 to drive the adding frame 10 to move left and right repeatedly.

[0028] Specifically, a controller is installed at the front end of the outer shell 1. The controller is electrically connected to motor 3 and motor 11. When adding chemicals, the device needs to be fixed at the top of the treatment device. When adding chemicals into the outer shell 1, they need to be mixed with the sludge. By starting motor 11, the connecting rod 14 is rotated left and right, and the adding frame 10 is moved left and right repeatedly to add chemicals to different positions of the treatment device, so that the chemicals are evenly distributed in the treatment device, allowing the sludge and chemicals to react fully, avoiding poor sludge dewatering effect, avoiding failure to achieve the expected treatment goal, and improving treatment efficiency.

[0029] Reference Figure 1 , Figure 5 and Figure 6 As shown, a motor 3 is fixedly connected to the left end of the outer casing 1. A gear 4 is fixedly connected to the drive end of the motor 3. Gear rings 5 ​​are meshed on both sides of the outer wall of the gear 4. The outer walls of the gear rings 5 ​​are rotatably connected to both sides of the inner wall of the outer casing 1. A connecting cylinder 18 is fixedly connected to the inner wall of the lower gear ring 5. A stirring rod 7 is fixedly connected to both sides of the outer wall of the connecting cylinder 18. A screw rod 6 is fixedly connected to the inner wall of the upper gear ring 5. The outer wall of the screw rod 6 is rotatably connected to the inner wall of the connecting cylinder 18 for stirring the medicine.

[0030] Specifically, when the stirring rod 7 is rotated, it will rotate on the inner wall of the connecting cylinder 18. By driving the screw rod 6 and the stirring rod 7 to rotate in different directions, the drug can be fully flowed and mixed in the entire device, avoiding concentration stratification or local concentration that is too high or too low. This ensures the accuracy and stability of the drug addition and helps to improve the effect of sludge dewatering treatment.

[0031] Working principle: First, the outer shell 1 is installed on top of the treatment device, and the medicine is added into the outer shell 1 through the feed inlet 2. The controller starts motor 3, which drives gear 4 to rotate. Gear 4 drives the toothed rings 5 ​​on both sides of the outer wall to rotate in different directions. The upper toothed ring 5 drives the spiral rod 6 to rotate, and the lower toothed ring 5 drives the connecting cylinder 18 to rotate. The connecting cylinder 18 drives the stirring rods 7 on both sides to rotate, stirring and mixing different medicines. After mixing, the controller opens the solenoid valve 8, which discharges the medicine inside the outer shell 1 downward and conveys it to the addition frame 10 and the nozzle through the folded tube 9, adding medicine downward to the treatment device. Next, the controller starts motor 11, which drives the transmission rod 12 to rotate and drives the slider 13 to slide on the inner wall of the slide groove 15, thereby driving the connecting rod 14 to rotate left and right repeatedly, and driving the connecting block 16 to slide on the inner wall of the connecting frame 17 and the addition frame 10 to slide left and right repeatedly, uniformly adding medicine to the inside of the treatment device.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
