Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology for dredging projects, and in particular to a mobile waterborne dredging wastewater dosing device. Background Technology

[0002] During dredging operations, dredging equipment generates a large amount of wastewater containing silt, suspended solids, and other impurities. Direct discharge of this wastewater will pollute the surrounding aquatic environment and disrupt the aquatic ecological balance. Currently, the treatment of dredging wastewater largely relies on fixed chemical dosing equipment on the shore, requiring the wastewater to be transported to a shore treatment area before chemicals are added for purification. This method has the following problems: The process of transporting residual water requires additional investment in equipment such as pipelines and pumps, which increases the project cost; fixed equipment cannot be moved with the dredging operation area, and when the dredging operation point is far from the shore, the residual water transport distance is too long, resulting in low treatment efficiency; in traditional dosing devices, the storage, mixing and transportation of chemicals are independent of each other, with low integration and cumbersome operation.

[0003] To address the shortcomings of the existing technology, this utility model proposes a mobile water-based dredging wastewater dosing device that integrates the chemical storage, mixing, transportation, and load-bearing structure into a single mobile water-based base. This eliminates the need for additional wastewater transportation and allows for flexible movement along with the dredging operation area, thereby improving the efficiency and convenience of wastewater treatment.

[0008] Preferably, the stirring and mixing mechanism further includes a stirring drive component, which includes a stirring motor and a stirring rod. The stirring rod is a hollow stirring rod with an internal cavity for the flow of the liquid medicine. The output end of the stirring motor is connected to the hollow stirring rod to drive the hollow stirring rod to rotate inside the mixing container. The mixing container is a mixing tank. The stirring and mixing mechanism also includes a cover covering the medicine storage tank.

[0018] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0019] This application discloses a mobile dredging wastewater dosing device. (Refer to...) Figure 1 The system includes a mobile support base 1, a chemical storage and delivery mechanism 2, a mixing mechanism 3, and a dosing mechanism 4. These mechanisms work together to complete the on-site dosing and treatment of dredged wastewater. The mobile support base 1 provides water support and buoyancy for the entire device and includes at least a working platform 11 and a buoyancy component. The working platform 11 is a flat structure made of corrosion-resistant metal. Its top surface provides the mounting foundation for the chemical storage and delivery mechanism 2, the mixing mechanism 3, and the dosing mechanism 4. Each mechanism is fixed to a designated position on the working platform 11 by bolts or welding to ensure stable installation. The buoyancy component is located at the bottom of the working platform 11 and provides buoyancy to the entire device, maintaining its floating state on the water and preventing it from sinking. In the above embodiment, the buoyancy component is a sealed buoyancy box 13, which is filled with lightweight buoyancy material (foam plastic) to further improve buoyancy performance. More preferably, the mobile support base 1 also includes a guardrail 12, which is vertically set along the edge of the work platform 11 to prevent workers or equipment from falling from the edge of the work platform 11 and improve work safety.

[0020] The chemical storage and conveying mechanism 2 is used to store different types of treatment chemicals and convey the chemicals to the mixing mechanism 3 or directly to the water body to be treated. It includes at least a chemical storage component, a chemical conveying pipe 23 component, and a control component. The chemical storage component is used to hold different types of chemicals (flocculators, disinfectants, etc.) and preferably multiple chemical storage tanks 21. Each tank is made of chemically resistant plastic or stainless steel. The top of the tank is equipped with a feeding port for easy replenishment of chemicals, and the side of the tank is equipped with a liquid level observation window to observe the remaining amount of chemicals in the tank in real time. The 23-way component of the chemical delivery pipe is used to connect the chemical storage component with the outside to realize chemical delivery. It includes a chemical mixing and delivery pipe 22 and multiple chemical delivery pipes 23: one end of each chemical delivery pipe 23 is connected to the bottom outlet of a chemical storage tank 21, and the other end is connected to the inlet of the chemical mixing and delivery pipe 22, forming a multi-inlet and one-outlet delivery path; the outlet of the chemical mixing and delivery pipe 22 has two connection methods, which can be selected according to actual needs. One is to connect to the mixing container of the stirring and mixing mechanism 3 to deliver the chemical into the mixing container for mixing; the other is to extend directly into the water body to be treated and discharge the chemical directly into the waste water. The control component is installed on the drug delivery pipe 23 and is used to control the on / off of drug delivery. It is preferably an electric valve 24. One electric valve 24 is installed on each drug delivery pipe 23. By opening and closing the electric valve 24, the delivery of the corresponding drug in the drug storage box 21 can be controlled independently, so as to realize the individual or combined delivery of different drugs.

[0021] Preferably, such as Figure 1 As shown, multiple medicine storage boxes 21 are provided, and the multiple medicine storage boxes 21 are distributed in an array (2×3 array) on the work platform 11. This distribution method can make more reasonable use of the space of the work platform 11, and at the same time facilitate the staff to add materials and maintain each box; and each medicine storage box 21 is equipped with a medicine delivery pipe 23 and an electric valve 24 to ensure that the medicine delivery of each box is independent and controllable.

[0022] The mixing mechanism 3 is used to mix the agent conveyed by the agent storage and conveying mechanism 2 with the water evenly, and includes at least a mixing container and an agent introduction component; preferably, it also includes a stirring drive component to further improve the mixing effect; the mixing container is a cylindrical structure with an open top, preferably a mixing tank 31, made of stainless steel, and its interior forms a mixing area between the agent and the liquid. The volume of the mixing tank 31 is designed according to the processing capacity requirements; the agent introduction component is used to introduce the agent in the agent storage and conveying mechanism 2 into the mixing container, preferably a suction pipe 33, one end of the suction pipe 33 is connected to the mixing container, and the other end is connected to the agent storage component (agent storage box 21), so as to suck the agent in the agent storage box 21 into the mixing container; The stirring drive component is used to stir the medicine and liquid in the mixing container to promote uniform mixing. It includes a stirring motor 32 and a stirring rod. The stirring motor 32 is fixedly installed on the top of the mixing container (or mounted on the working platform 11 via a bracket, with its output end extending into the mixing container). The stirring rod is connected to the output end of the stirring motor 32. Preferably, the stirring rod is a hollow stirring rod 34, with an internal cavity for the flow of the medicine liquid. Several liquid outlet holes can be formed on the side wall of the hollow stirring rod 34, communicating with the cavity. During stirring... The liquid medicine can be evenly sprayed into the mixing container through the liquid outlet to further improve the mixing uniformity. More preferably, the stirring and mixing mechanism 3 also includes a cover 35, which is placed above the medicine storage box 21. The cover 35 is designed to fit the size of the medicine storage box 21 and is made of the same material as the box. It has the functions of dust prevention and preventing drug volatilization, and at the same time provides an installation base for the drug introduction component. By installing a suction pump inside the cover 35, the suction pump guides the medicine inside the medicine storage box 21 to the hollow stirring rod 34 through the suction pipe 33.

[0023] Furthermore, the stirring motor 32 is fixed to the center of the top of the mixing tank 31 via a flange, and its output end is connected to the hollow stirring rod via a coupling; the coupling is also provided with a pipe to provide a flow area between the hollow stirring rod 34 and the suction pipe 33.

[0024] The dosing mechanism 4 is used to pump the water to be treated to the mixing mechanism 3 (to mix with the reagent), or to transport the reagent mixed in the mixing mechanism 3 to the water to be treated. It includes at least a delivery pipeline, a power component, and a flow control component. The delivery pipeline is a tubular structure, preferably a dosing pipeline 41, made of corrosion-resistant material. One end of the dosing pipeline 41 is connected to the mixing container (mixing tank 31) of the mixing mechanism 3, and the other end extends into the water to be treated, forming a fluid delivery passage. The power unit is used to drive the fluid (water to be treated or mixed reagent) to flow in the delivery pipeline. It is preferably a pump body 43, which is installed in series on the dosing pipeline 41. By rotating the pump body 43 forward or reverse, two functions can be achieved: when rotating forward, the water to be treated is drawn into the mixing container and mixed with the reagent; when rotating in reverse, the mixed reagent in the mixing container is discharged into the water to be treated. The flow control component is used to control the flow rate of the fluid in the delivery pipeline to avoid excessive or insufficient flow affecting the treatment effect. It preferably includes a first valve 42 and a second valve 44, which are connected in series on the dosing pipeline 41. The first valve 42 is located on the side of the pump body 43 closer to the mixing container, and the second valve 44 is located on the side of the pump body 43 away from the mixing container. By adjusting the opening degree of the first valve 42 and the second valve 44, the fluid flow rate can be controlled in a coordinated manner. At the same time, when the equipment is under maintenance, closing the two valves can achieve pipeline sealing and prevent fluid leakage.

[0025] Preferably, a filter element is installed at one end of the dosing pipe 41 that extends into the water body to be treated. The filter element is a mesh filter cover with a pore size of 0.5-1mm. It is used to block impurities such as silt and suspended solids in the water body from entering the dosing pipe 41, so as to avoid blockage of the pipe or pump body 43 and extend the service life of the equipment.

[0026] In actual use, the mobile support base 1 is moved to the area where the dredged wastewater is to be treated. The buoyancy component provides buoyancy, allowing the device to float stably on the water surface. Different types of treatment agents are added to each tank through the feeding port on the top of the agent storage tank 21. The agent storage volume is confirmed through the liquid level observation window. According to the treatment requirements, the electric valve 24 on the corresponding agent delivery pipe 23 is opened, and the agent in the agent storage tank 21 flows into the agent mixing delivery pipe 22 through the agent delivery pipe 23. If it is necessary to mix the agents, the agent mixing delivery pipe 22 is connected to the mixing tank 31 of the stirring and mixing mechanism 3, or the agents are introduced into the mixing tank 31 from the top of the agent storage tank 21 through the suction pipe 33. If direct dosing is required, the chemical mixing and delivery pipe 22 is extended directly to the water body to be treated, and the chemical is directly discharged into the water body. When mixing and adding chemicals, the pump body 43 of the dosing mechanism 4 is started (forward rotation) to draw the water body to be treated into the mixing tank 31. The stirring motor 32 is started, and the stirring motor 32 drives the hollow stirring rod 34 to rotate. The chemical solution in the hollow stirring rod 34 is sprayed into the mixing tank 31 through the liquid outlet and fully mixed with the water body. After mixing is completed, the pump body 43 is controlled to reverse, and the chemical mixture inside the mixing tank 31 is discharged into the water body to be treated through the dosing pipe 41. At the same time, the first valve 42 and the second valve 44 are adjusted to control the discharge flow rate of the mixture and complete the residual water dosing treatment.

[0027] It is worth noting that the reagent mixing and delivery pipe passage is suitable for low-viscosity reagents (flocculators), while the suction pipe passage (including the suction pump) is suitable for high-viscosity reagents (coagulants). The two passages are controlled by an electric valve (reagent delivery pipe) and a solenoid valve (suction pipe), and cannot be used simultaneously to avoid overloading the mixing tank.

[0028] In this embodiment, the device can be flexibly moved to the work site for treating dredged wastewater. The six chemical storage tanks 21 can store flocculants, coagulants, and disinfectants respectively. The electric valve 24 is a Q911F-16P; the stirring motor 32 is a Y100L-2; the pump body 43 is an ISG50-160; and the first valve 42 and the second valve 44 are ball valves.
