Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to wastewater treatment devices. Background Technology

[0002] Dairy wastewater is characterized by its complex composition and high pollutant concentration. Direct discharge without treatment will severely pollute water bodies, soil, and other ecological environments. Therefore, it must undergo strict treatment to meet standards before discharge or recycling. Chemical dosing is a core step in dairy wastewater purification. By adding targeted agents to the wastewater, reactions such as flocculation, neutralization, and oxidation-reduction of pollutants are achieved, effectively removing harmful substances and laying the foundation for subsequent sedimentation and filtration processes. However, existing dosing devices generally use metering pumps. While this achieves automated control, it has several drawbacks: high equipment purchase and operating costs; long-term use, the pump body is prone to clogging and wear due to solid impurities in the wastewater or agent crystals, leading to a significant decrease in dosing accuracy; and the metering pump requires additional electricity, increasing system energy consumption.

[0045] Traditional dosing systems for dairy (industrial) wastewater treatment generally use metering pumps for adding chemicals. However, this method has limitations such as high equipment purchase and operating costs, pump wear due to impurities or chemical crystallization leading to decreased metering accuracy, and the need for additional electricity to drive the system, resulting in increased energy consumption and maintenance costs. These limitations make it difficult to meet the demands for precise and efficient treatment.

[0046] Please refer to the following for details. Figures 1 to 4This application discloses a wastewater treatment device. The device includes a treatment tank assembly 1, a chemical storage tank assembly 3, and a triggering assembly 4. The treatment tank assembly 1 has a treatment chamber 108, an inlet 103 and an outlet 105 communicating with the treatment chamber 108, and a mounting hole communicating with the treatment chamber 108. The chemical storage tank assembly 3 includes a chemical storage tank 301 and an outlet pipe 306. The chemical storage tank 301 has a chemical storage chamber 312, and the outlet pipe 306 passes through the mounting hole, with one end connected to the chemical storage tank 301 and communicating with the chemical storage chamber 312, and the other end extending into the treatment chamber 108. The triggering assembly 4 includes a valve body 404, a valve core 403, a rotating shaft 402, and an impeller 401. The valve body 404 is located at the end of the outlet pipe 306 extending into the treatment chamber 108, and the valve core 403 is located inside the valve body 404. One end of the rotating shaft 402 is connected to the valve core 403, and the other end is connected to the impeller 401. Impeller 401 is provided corresponding to inlet 103. The water flow from inlet 103 is suitable for impacting impeller 401, so that impeller 401 drives shaft 402 and valve core 403 to rotate. When valve core 403 rotates to the open state, it connects outlet pipe 306 and treatment chamber 108.

[0047] Specifically, such as Figure 2 As shown, the treatment tank assembly 1 serves as the core container for wastewater treatment, with an internal treatment chamber 108 for holding the wastewater to be treated. The inlet 103 and outlet 105 are used for the introduction and discharge of wastewater, respectively. For example, the inlet 103 is used to connect to an inlet pipe, and the outlet 105 is used to connect to an outlet pipe. Furthermore, the treatment tank assembly 1 is also provided with mounting holes to provide interfaces for the installation of other functional components. For instance, the treatment tank assembly 1 can adopt an integrally formed cylindrical structure, with its inlet 103 and outlet 105 connected to external pipelines via pre-reserved pipe interfaces, and the mounting holes directly formed on the tank wall.

[0048] The chemical storage tank assembly 3 stores the chemical agents required for wastewater treatment and transports them to the treatment chamber 108. The storage tank 301 has a storage chamber 312 inside to hold the agents. One end of the outlet pipe 306 connects to the storage tank 301 and communicates with the storage chamber 312, while the other end passes through the mounting hole of the treatment tank assembly 1 and extends into the treatment chamber 108. For example, the storage tank 301 can be a simple sealed container with an interface for connection to the outlet pipe 306. The outlet pipe 306 can be a flexible or rigid pipe, the length and curvature of which can be adjusted according to actual installation requirements. As an optional implementation, the storage tank 301 can be designed with a removable cover to facilitate agent filling and cleaning of the storage chamber 312. The outlet pipe 306 can be a fixed-length rigid pipe, connected to the storage tank 301 and the treatment tank assembly 1 by threads or snap-fit. For example, the outlet pipe 306 is fixedly connected to the connecting pipe flange 405, which is fixedly connected to the top of the treatment tank assembly 1.

[0049] like Figure 2 and Figure 4 As shown, the triggering component 4 is the key to the automatic dosing of this device. The triggering component 4 includes a valve body 404, a valve core 403, a rotating shaft 402, and an impeller 401. The valve body 404 is located at one end of the outlet pipe 306 that extends into the treatment chamber 108, and the valve core 403 is located inside the valve body 404. One end of the rotating shaft 402 is connected to the valve core 403, and the other end is connected to the impeller 401. The impeller 401 is positioned corresponding to the inlet 103. When the water flowing out of the inlet 103 impacts the impeller 401, the impeller 401 is driven to rotate, which in turn drives the rotating shaft 402 and the valve core 403 to rotate. When the valve core 403 rotates to a specific position, its internal channel aligns with the channel of the valve body 404, thereby connecting the outlet pipe 306 and the treatment chamber 108, realizing the automatic delivery of the agent. For example, the impeller 401 can be designed as a multi-blade structure, and the angle and number of its blades can be adjusted according to the expected water flow impact force to ensure effective rotation under different water flow conditions. The valve core 403 can be a cylinder or sphere with a through hole, which can be aligned or offset with the chemical channel on the valve body 404 by rotation.

[0050] The wastewater treatment device of this application achieves automatic dosing of chemicals by utilizing the kinetic energy of the influent water flow to drive the trigger component 4, avoiding the dependence on external power and complex control systems of traditional quantitative pump dosing methods. Therefore, this device effectively reduces equipment purchase and operating costs, minimizes maintenance needs and metering accuracy degradation caused by pump blockage and wear, and significantly reduces energy consumption, providing an economical, efficient, and easy-to-maintain dosing solution for dairy (industrial) wastewater treatment.

[0051] This application further proposes that the trigger component 4 includes a reset element (not shown in the figure), the reset element is connected to the valve body 404 and the valve core 403, and the reset element is used to drive the valve core 403 to reset to the closed state.

[0052] The main function of the reset element is to automatically return the valve core 403 to a preset initial position, typically the closed state, after the external force (such as water flow impact) disappears. The reset element can be a spring, a counterweight, a shape memory alloy, or other mechanical structure with elasticity or potential energy storage capabilities. For example, a torsion spring or a helical spring can be used, storing energy through its deformation and releasing it when the water flow impact weakens or disappears, thereby driving the valve core 403 to reset.

[0053] The core function of the reset component is to provide a reverse driving force when the water flow from the inlet 103 stops impacting the impeller 401, or when the water flow impact force is insufficient to maintain the valve core 403 in the open state, so that the reset component can automatically return the valve core 403 from the open state to the closed state. For example, when the water flow impacts the impeller 401, the impeller 401 drives the shaft 402 and the valve core 403 to rotate, while compressing or stretching the reset spring to store energy; when the water flow stops, the spring releases the stored energy, pushing the valve core 403 to rotate in the opposite direction until the connection between the outlet pipe 306 and the treatment chamber 108 is completely closed.

[0054] By incorporating a reset element in the trigger assembly 4, connecting it to the valve body 404 and the valve core 403, and using it to reset the valve core 403 to the closed state, this application effectively solves the problem of the lack of an automatic reset mechanism for the valve core 403 during the chemical addition process. When the water flow at the inlet 103 stops impacting the impeller 401, the reset element can promptly and automatically restore the valve core 403 from the open state to the closed state, thereby cutting off the chemical outflow channel between the outlet pipe 306 and the treatment chamber 108. This avoids continuous chemical outflow caused by the valve core 403 remaining open for a long time, effectively preventing chemical waste and ensuring the accuracy and controllability of chemical addition. Simultaneously, this automatic reset mechanism requires no additional manual intervention or complex control system, simplifying the operation and maintenance of the device and improving the overall operating efficiency and economy of the wastewater treatment device.

[0055] like Figure 5 As shown, this application further proposes that the medicine storage tank 301 includes a tank body, a tank lid 303, and a sealing ring 309. The tank body has a medicine storage cavity 312, and one end of the liquid outlet pipe 306 is connected to the tank body; the tank lid 303 is movably connected to the tank body to open or close the medicine storage cavity 312; the sealing ring 309 is located on the tank body and is used to seal the connection gap between the tank body and the tank lid 303.

[0056] Specifically, the tank body is the core component of the storage tank assembly 3, and its interior has a storage chamber 312 for safely and stably storing the reagents required for treating the wastewater. One end of the outlet pipe 306 is connected to the tank body to ensure that the reagents can be smoothly delivered from the storage chamber 312 to the treatment chamber 108. The tank body structure can be cylindrical, square, or conical to optimize the storage and retrieval efficiency of the reagents. The lid 303 is movably connected to the tank body, and its main function is to open and close the storage chamber 312. The lid 303 can adopt various connection methods, such as threaded engagement, snap-on, hinged flip-top, or compression type, to provide convenient and reliable opening and closing operations. For example, it is fixedly connected to one side of the top of the tank body by a hinge 302, and the lid 303 is fixedly connected to the other end of the hinge 302.

[0057] The sealing ring 309 is located at the connection gap between the barrel body and the barrel lid 303, and its core function is to ensure the airtightness of the medicine storage chamber 312. By forming a tight physical barrier between the barrel body and the barrel lid 303, the sealing ring 309 can effectively prevent the medicine in the medicine storage chamber 312 from leaking out, while preventing external air, dust, or other contaminants from entering the medicine storage chamber 312, thereby ensuring the purity and stability of the medicine. The sealing ring 309 is made of a material with good corrosion resistance and elasticity, such as ethylene propylene rubber, fluororubber, silicone rubber, or polytetrafluoroethylene. Its structural form can be an O-ring, a flat washer, or a lip seal 309.

[0058] This application further proposes that the lid 303 of the medicine storage tank 301 is provided with a filling pipe 304 that connects to the medicine storage cavity 312.

[0059] Specifically, the filling tube 304 is a channel for replenishing the medicine into the medicine storage chamber 312. The filling tube 304 can be integrally formed with the lid 303, creating a compact and well-sealed fixed channel, thereby reducing additional connecting parts. Alternatively, the filling tube 304 can also be a separate component, detachably fixed to the lid 303 via threaded connections, snap-fit ​​connections, or quick couplings, facilitating replacement or maintenance of the filling tube 304 and allowing selection of different materials for the filling tube 304 based on the characteristics of the medicine being added. Furthermore, the filling tube 304 can also be in the form of a flexible hose, with one end fixed to the lid 303 and the other end connectable to an external medicine source, providing greater operational flexibility.

[0060] With the above technical solution, users can add medicine to the storage chamber 312 without frequently opening the lid 303 of the entire medicine storage tank 301. This significantly reduces the risk of wear and failure of the sealing ring 309 between the lid 303 and the tank body, thereby effectively maintaining the overall sealing performance of the medicine storage tank 301. The medicine is directly injected into the storage chamber 312 through the filling pipe 304, avoiding exposure of the medicine to the external environment during the addition process and reducing the possibility of medicine contamination and leakage.

[0061] This application further proposes that the medicine storage tank assembly 3 also includes a filter element 308, which is disposed in the medicine storage cavity 312.

[0062] Specifically, the filter element 308 can be a filter screen with a specific pore size, woven from metal wire, plastic fiber, or synthetic fabric, to physically block larger particles from passing through. The filter element 308 is designed to ensure that the reagent is pre-purified before leaving the drug storage chamber 312. By placing the filter element 308 within the drug storage chamber 312, this pre-filtration position effectively intercepts impurities at the source of the reagent, preventing them from entering subsequent delivery pipelines and valve systems.

[0063] Through the above technical solution, before the agent is delivered from the storage chamber 312 to the outlet pipe 306, the filter element 308 can effectively intercept impurities such as solid particles, crystals, or flocculants that may be present in the agent, thereby avoiding the blockage problem of the outlet pipe 306 caused by the accumulation of impurities. At the same time, since the impurities are effectively removed, the wear on the valve body 404 and valve core 403 in the trigger assembly 4 during the passage of the agent is also reduced, extending their service life and ensuring the smoothness and reliability of the valve core 403 rotating to the open state.

[0064] This application further proposes that the inner wall of the drug storage chamber 312 is provided with an installation groove 311, and the filter element 308 is snapped into the installation groove 311 by an installation bracket 310. The installation groove 311 is a structure provided on the inner wall of the drug storage chamber 312, and its main function is to provide a preset, stable fixed position for the filter element 308. The installation groove 311 can be designed as a groove extending vertically to accommodate the installation and removal of the filter element 308 in the vertical direction. The installation groove 311 can be formed integrally into the inner wall of the drug storage tank 301 by a mold, or it can be achieved through subsequent processing, such as milling or welding of additional structures. The installation bracket 310 is an intermediate structure connecting the filter element 308 and the installation groove 311, and its function is to provide a snap-fit ​​function, so that the filter element 308 can be firmly fixed in the drug storage chamber 312. The mounting bracket 310 can be integrally formed with the filter element 308, for example, by setting a frame with snap-fit ​​on the edge of the filter screen; or it can be a separate component, connected to the filter element 308 by means of threads, welding, or bonding, and then its snap-fit ​​structure engages with the mounting groove 311. Specifically, the snap-fit ​​can be achieved by setting elastic claws or protrusions on the mounting bracket 310, which can be pressed into or slid into the mounting groove 311 during installation, using the elastic deformation of the material to generate a clamping force. This connection method ensures stability while also providing convenience for the daily maintenance and replacement of the filter element 308.

[0065] This application further proposes that the side wall of the medicine storage tank 301 is provided with a liquid level observation window 305.

[0066] The liquid level observation window 305 is a transparent or semi-transparent structure installed on the side wall of the medicine storage tank 301. Its main function is to provide a direct way for operators to monitor the liquid level of the medicine in the storage chamber 312 in real time. Specifically, the liquid level observation window 305 can be made of a corrosion-resistant transparent material (such as glass, polycarbonate, or acrylic) and embedded in the side wall of the medicine storage tank 301. For ease of observation, the liquid level observation window 305 can be designed as a strip window. Furthermore, the surface of the liquid level observation window 305 can be equipped with graduation markings to provide quantitative information on the liquid level, thereby assisting operators in determining the remaining amount of medicine and when to replenish it.

[0067] In one embodiment, the outlet pipe 306 is equipped with an outlet control valve 307, which is a control device installed on the outlet pipe 306. Its core function is to manually open or close the path of the agent flowing from the storage tank 301 to the processing chamber 108. Specifically, the outlet control valve 307 can take various forms, such as a ball valve, a gate valve, or a butterfly valve. By operating the outlet control valve 307, real-time control of the agent outlet can be achieved. For example, in the event of equipment maintenance, agent replacement, or emergency, the agent supply can be quickly cut off, ensuring operational safety and the flexibility of the processing procedure.

[0068] Please refer to the reference. Figure 2 and Figure 6 This application further proposes that the treatment tank assembly 1 includes a treatment tank 101, a conical sedimentation tank 102, and a slag discharge pipe 106. The treatment tank 101, as the core container of the wastewater treatment device, has a treatment chamber 108 inside to hold the wastewater to be treated and to provide a stable space for subsequent reactions such as chemical dosing and stirring. The treatment tank 101 has an inlet 103 and an outlet 105, wherein the height of the inlet 103 is higher than that of the outlet 105. This height difference design allows gravity to guide the wastewater to form a relatively stable flow field within the treatment chamber 108, promoting the natural sedimentation of suspended solids as it flows through the treatment chamber 108, and also helps to extend the residence time of the wastewater within the treatment chamber 108, thereby improving treatment efficiency. In addition, the treatment tank 101 also serves a load-bearing function, supporting the top chemical storage tank assembly 3 and the middle stirring assembly 2.

[0069] A conical settling cylinder 102 is located at the bottom of the processing tank 101, and its interior contains a settling chamber 109, which is connected to the processing chamber 108. The unique geometry of the conical settling cylinder 102 effectively utilizes gravity to collect and concentrate the solid particles (i.e., slag) settling from the processing chamber 108 to its bottom. This design prevents slag from dispersing or adhering to the tank wall within the processing chamber 108, thereby significantly improving the efficiency of solid-liquid separation and laying the foundation for subsequent slag removal.

[0070] The slag discharge pipe 106 is connected to the bottom of the conical settling cylinder 102 and communicates with the settling chamber 109. This slag discharge pipe 106 serves as a dedicated discharge channel for slag, ensuring that the concentrated slag settled at the bottom of the conical settling cylinder 102 can be discharged efficiently and conveniently. Through the slag discharge pipe 106, accumulated slag can be removed periodically or continuously, preventing excessive accumulation in the settling chamber 109, thus maintaining the unobstructed flow of the settling chamber 109 and avoiding slag backflow or negative impacts on the treatment effect.

[0071] Through the above technical solution, after the wastewater enters the treatment tank 101, the inlet 103 is positioned higher than the outlet 105, creating a flow pattern conducive to sedimentation. This allows sufficient time and conditions for the suspended solids in the wastewater to undergo initial sedimentation. Subsequently, these settled solid particles are efficiently collected and concentrated to the bottom of the conical sedimentation tank 102 under the guidance of its conical structure. Finally, the accumulated sludge can be conveniently and quickly discharged through the sludge discharge pipe 106 connected to the bottom of the conical sedimentation tank 102, effectively preventing the accumulation and backflow of sludge in the treatment chamber 108, thereby significantly improving the sedimentation effect and solid-liquid separation efficiency in the wastewater treatment process.

[0072] like Figure 6 As shown, this application further proposes that the processing tank assembly 1 also includes a level gauge 104, which is disposed in the processing chamber 108; optionally, the processing tank assembly 1 also includes a support frame 107, which is supported on the bottom of the conical sedimentation cylinder 102.

[0073] The level gauge 104 is a measuring device used to monitor the liquid level in the processing chamber 108 in real time. Specifically, the level gauge 104 can be implemented using various technologies. For example, it can be a float-type level gauge, which indicates or controls the liquid level by the rise and fall of a float; or it can be an ultrasonic level gauge, which accurately calculates the liquid level using the time difference between the transmission and reception of ultrasonic pulses; or it can be a hydrostatic level gauge, which calculates the liquid level by measuring the hydrostatic pressure generated by the liquid.

[0074] The support frame 107 is a component used to provide structural support and stability. Specifically, the support frame 107 can be designed in various forms, for example, it can be a structure composed of multiple pillars that are evenly distributed and fixed to the bottom periphery of the conical sedimentation tank 102, and further fixed to the ground or equipment base to provide stable vertical support.

[0075] Through the above technical solution, a level gauge 104 is installed in the treatment tank assembly 1, which can monitor the wastewater level in the treatment chamber 108 in real time and accurately. This allows operators or the automated control system to precisely adjust the influent and effluent flow rates or reagent dosage according to the actual liquid level, ensuring that the sedimentation reaction takes place under optimal liquid level conditions. This effectively avoids problems such as decreased treatment efficiency or poor sedimentation effect caused by excessively high or low liquid levels. At the same time, by installing a support frame 107 at the bottom of the conical sedimentation tank 102, a stable mechanical support is provided for the conical sedimentation tank 102, effectively preventing displacement, tilting, or structural deformation under conditions such as wastewater flow, sediment accumulation, or external vibration. This significantly reduces the vibration risk and potential damage during equipment operation, thereby improving the operational reliability and service life of the entire wastewater treatment device.

[0076] like Figure 2 and Figure 7 As shown, this application further proposes that, in order to ensure that the reagent and wastewater can be fully and uniformly mixed, thereby improving the treatment effect, the wastewater treatment device also includes a stirring assembly 2. The stirring assembly 2 is designed to promote the uniform mixing of wastewater and reagent through mechanical action, ensuring that the reaction proceeds fully, thereby improving the overall treatment effect. Specifically, the stirring assembly 2 includes a stirring drive 202, a stirring shaft 203, and stirring blades 205.

[0077] The stirring drive component 202 is the component that provides the power source for the stirring assembly 2, and it is connected to the treatment tank assembly 1. The stirring drive component 202 can be an electric motor. By connecting the stirring drive component 202 to the treatment tank assembly 1, a stable and continuous power source can be provided for the stirring action, solving the problem of insufficient manual or external drive, and enabling the stirring action to be performed continuously and efficiently. The design of the stirring shaft 203 ensures the effective transmission of power from the external stirring drive component 202 to the internal treatment chamber 108, so that the stirring force can be directly applied to the core area of ​​the wastewater. The stirring blade 205 is the core component that is in direct contact with the fluid and generates shear force, eddies, and thrust through rotation to achieve fluid mixing. Its specific form is diverse. For example, a paddle-type stirring blade 205 can be used, which is suitable for the gentle mixing of medium and low viscosity fluids; a turbine-type stirring blade 205 can also be used to provide high shear force, which is suitable for dispersion or emulsification operations. The rotation of the stirring blades 205 within the treatment chamber 108 generates powerful eddies and mixing forces, enabling the reagents to disperse rapidly and come into full contact with the wastewater, effectively avoiding incomplete reactions caused by uneven local concentrations.

[0078] In one embodiment, the stirring drive 202 is securely mounted on the top of the processing tank 101 via an L-shaped motor plate 201. This ensures the installation stability of the stirring drive 202, makes reasonable use of space, and avoids interference with the drug storage tank assembly 3. Optionally, the bottom of the bearing seat 204 is fixedly connected to the top of the processing tank 101, and the stirring shaft 203 is connected to the processing tank 101 via the bearing seat 204. This reduces the frictional force when the stirring shaft 203 rotates, improves the stability of rotation, and prevents shaking from affecting the stirring effect.

[0079] Through the above technical solution, after automatic dosing in the wastewater treatment device, the stirring component 2 can be activated as needed. The stirring drive component 202 drives the stirring shaft 203, which in turn drives the stirring blades 205 to rotate within the treatment chamber 108, thereby forcibly mixing the wastewater and the reagents. This not only accelerates the chemical reaction rate between the reagents and pollutants in the wastewater, improving the sufficiency and efficiency of the reaction, but also avoids localized over- or under-dosing of reagents, thus optimizing reagent utilization efficiency and reducing treatment costs. Simultaneously, the uniform mixing lays a solid foundation for subsequent treatment processes such as sedimentation and filtration, significantly improving the overall compliance rate and stability of wastewater treatment.

Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
