Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a fully automatic dosing device for sludge dewatering. Background Technology

[0002] Sludge dewatering is a sludge treatment method that removes water from fluidized raw, concentrated, or digested sludge, transforming it into semi-solid or solid sludge blocks. This process aims to reduce sludge volume for easier subsequent transportation, storage, and final disposal. After dewatering, the moisture content of sludge can be significantly reduced, typically to between 55% and 80%, depending on the properties of the sludge and the efficiency of the dewatering equipment. Sludge dewatering plays a crucial role in sludge treatment processes and is one of the key steps in achieving sludge reduction, stabilization, and harmlessness.

[0003] During sludge dewatering, chemicals need to be mixed with the sludge, thus requiring the use of a dosing device. Existing dosing devices typically mix chemicals and water to form a solution of the required concentration. However, current technology cannot mix multiple solutions simultaneously, resulting in the inability to dewater multiple sludge samples at the same time. This limits the overall progress of sludge treatment, leading to low treatment efficiency. This may prolong the sludge treatment cycle and increase treatment costs. Furthermore, large chemical particles cannot be pulverized during mixing. Due to their relatively small surface area, large chemical particles have limited contact area with wastewater, which may result in insufficient reaction with pollutants in the wastewater, thereby reducing the utilization rate of the chemicals.

[0004] Therefore, it is necessary to provide a new fully automated dosing device for sludge dewatering to solve the above-mentioned technical problems. Utility Model Content

A storage tank 10 located on the top of the support plate 3 is simultaneously rotated by the second gear 8 and multiple sets of drive rods 9 to simultaneously douse multiple sludge. The mixing effect of the medicine in the storage tank 10 improves the dosing efficiency of sludge dewatering. The storage tank 10 is provided with an inlet 11 on the outside. A filter plate 12 is slidably connected to the inner wall of the inlet 11. The filter plate 12 achieves the effect of filtering large particles of medicine powder. A box body 13 is fixedly connected to the top of the inlet 11. A second motor 14 is fixedly connected to one side of the box body 13. A fixing rod 15 is fixedly connected to the output end of the second motor 14. A crushing roller 16 is installed on the outside of the fixing rod 15. The crushing roller 16 achieves the effect of crushing large particles of medicine, avoiding the problem that large particles of medicine may not be completely dissolved or dispersed during sludge dewatering.

[0025] A connecting frame 17 is fixedly connected to the bottom of the drive rod 9, and a stirring shaft 18 is fixedly connected to the bottom of the connecting frame 17. The stirring shaft 18 is used to mix the chemicals. A protective shell 19 is installed at the bottom of the connecting frame 17, and a heating rod 20 is installed inside the protective shell 19. The heating rod 20 is a prior art technology that achieves the effect of heating the chemicals, avoiding the problem that the inability to heat the chemicals may affect the flocculation and sedimentation processes of sludge, thereby reducing the efficiency and quality of sludge dewatering. A fixing frame 21 is fixedly connected to the bottom of the support frame 5, and the outer side of the drive rod 9 is rotatably connected to the inner wall of the fixing frame 21. A mounting bracket is fixedly connected to the outer side of the support plate 3. The mounting plate 22 has a liquid pump 23 for adding chemicals installed on its top. The inlet of the liquid pump 23 is connected to the outside of the storage tank 10 through a pipe. The output end of the liquid pump 23 is provided with a connecting hose 24.

A drain pipe 29 is provided on the outside of the cylinder 27.

[0026] A connecting rod 30 is rotatably connected to the inner wall of the feed inlet 11, and a connecting block 31 is fixedly connected to the outer side of the connecting rod 30. There are two sets of connecting rods 30, which are connected by meshing gears. One set of connecting rods 30 is connected to the fixed rod 15 via belt drive. The medicine is added into the medicine storage tank 10 through the feed inlet 11, and the large particles of medicine are filtered through the filter plate 12. The filter plate 12 has an inclined angle, and the large particles of medicine fall into the box 13. The second motor 14 is started to drive the fixed rod 15 and the crushing roller 16 to rotate. The crushing roller 16 crushes the large particles of medicine, avoiding the problem that the large particles of medicine may not be completely dissolved or dispersed during the sludge dewatering process.

[0027] Working Principle: In operation, the medicine is added to the storage tank 10 through the feed inlet 11. Large particles of medicine are filtered through the filter plate 12, which has an inclined angle. Large particles fall into the casing 13. The second motor 14 is activated, driving the fixed rod 15 and the crushing roller 16 to rotate. The crushing roller 16 crushes the large particles, preventing them from being completely dissolved or dispersed during sludge dewatering. The fixed rod 15 drives the connecting rod 30 and the connecting block 31 to rotate, causing the connecting block 31 to strike the filter plate 12, improving its filtration efficiency. The first motor 6 is activated, driving the first gear 7 to rotate, causing multiple sets of second gears 8 to rotate simultaneously. The second gear 8 and multiple sets of drive rods 9 rotate simultaneously to achieve the effect of mixing the agents in multiple sets of storage tanks 10 at the same time, which improves the efficiency of sludge dewatering and dosing. The mixing effect of the agents is achieved by the stirring shaft 18, and the heating effect of the agents is achieved by the heating rod 20. This avoids the problem that the flocculation and sedimentation of sludge may be affected if the agents cannot be heated, thereby reducing the efficiency and quality of sludge dewatering. The liquid pump 23 is started to extract the liquid from the storage tank 10. The liquid flow meter 25 is used to monitor the dosing flow rate. The sludge inside the cylinder 27 is dosed and dewatered by connecting the hose 24 and the nozzle 26. The pH sensor 28 is used to monitor the acidity and alkalinity of the sludge so as to adjust the dosage of the agents as needed.
