Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to an integrated device for fine dosing of chemicals in wastewater treatment. Background Technology

[0002] In industrial and municipal wastewater treatment processes, the addition of chemical agents is a crucial step, often involving various chemicals such as coagulants, flocculants, coagulant aids, and pH adjusters. To achieve optimal treatment results (such as best flocculation and sedimentation efficiency, lowest effluent turbidity, and most stable pH value), it is usually necessary to simultaneously add two or more agent solutions to the wastewater according to a preset, strict volume or mass ratio. This synergistic effect of multiple agents requires the dosing system to have high-precision proportional control capabilities, the core of which lies in the real-time and accurate metering and delivery of the flow rate of each agent. Currently, common implementation methods often rely on multiple independent metering pumps, peristaltic pumps, or coarse control by adjusting valve opening and time, and their control systems are often relatively independent or simply interconnected.

[0003] However, existing technologies have significant shortcomings in achieving precise proportional control. First, the system's dosing accuracy is constrained by various factors, such as the long-term accuracy drift of a single metering pump, the nonlinearity of flow characteristics due to viscosity differences between different chemicals, and the significant impact of pipeline pressure fluctuations on low-flow-rate chemical dosing. Second, existing equipment often lacks effective online real-time calibration and compensation mechanisms, failing to dynamically correct proportional deviations caused by the aforementioned factors. This inaccurate proportional control directly leads to serious consequences: from a technical perspective, chemicals deviating from the optimal ratio cannot achieve the expected synergistic effect in wastewater, potentially resulting in poor floc formation, decreased sedimentation efficiency, and effluent quality exceeding standards, directly affecting the stability and reliability of the treatment effect. From an economic perspective, to compensate for poor results, there is often a tendency to overdose a certain chemical, which not only wastes expensive chemicals and significantly increases the operating cost per ton of wastewater, but may also introduce new secondary pollution risks due to chemical residues, ultimately severely impacting the practical value and economic efficiency of the entire chemical dosing system. Therefore, developing an integrated precision dosing device capable of high-precision, adaptive, and synchronous control of multiple reagent ratios has become a key requirement for improving wastewater treatment efficiency and reducing operating costs.

[0008] Preferably, the circulation assembly includes a volume sleeve that is connected to the upper end of a plurality of right-angle tubes. A plurality of fixed cavities are provided at equal intervals along the circumference inside the volume sleeve. A piston sleeve is slidably connected to each fixed cavity, and a return spring is installed on the upper end face of each piston sleeve, and the return spring abuts against the inside of the volume sleeve.

[0009] Preferably, an internal spring is installed inside the piston sleeve, and a follower plate is installed at the lower end of the internal spring. The follower plate is slidably connected inside the piston sleeve in a sealed manner. The lower end of the piston sleeve is threaded with a follower sleeve. When there is no external pressure, the follower plate is attached to the follower sleeve.

[0010] Preferably, a drive shaft is coaxially rotatably provided inside the volume sleeve, and a swashplate is provided on the outer wall of the drive shaft. A plurality of rolling balls are rotatably attached to the lower end face of the swashplate, and a rocking disk is attached to the lower end of the plurality of rolling balls. An intermediate ball is rotatably mounted on the upper end of each piston sleeve, and the intermediate ball is attached to the lower end face of the rocking disk.

[0011] Preferably, the unidirectional component includes intermediate sleeves threaded to both sides of the right-angle tube, and each intermediate sleeve is threaded to the outer side with a feed pipe.

[0014] Preferably, a fixing sleeve is provided on the outer side of the volume sleeve, and a motor is provided on the fixing sleeve, with the drive shaft of the motor connected to the transmission shaft.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an integrated device for fine dosing of chemicals in wastewater treatment, which has the following beneficial effects: This invention achieves long-term, high-precision, and high-reliability control of the dosage ratio of various agents through a unique mechanical proportional control principle. Its core lies in the independently designed adjustment component for each agent's pathway. By rotating the adjustment sleeve, the preload of the adjustment spring acting on the sealing sleeve is changed, thereby setting the baseline proportional parameters for that agent. During the working cycle, the pressure generated by the downward movement of the piston sleeve of the circulation component is first used to compress the internal spring. Only when the compression force of the internal spring increases to equal the preset adjustment spring preload does the corresponding sealing sleeve open and begin discharging the agent. This ensures that the effective discharge stroke of each agent is inversely proportional to its preset preload, ultimately achieving a strictly proportional output of different agent volumes in each working cycle. This completely eliminates the reliance on electronic sensors and complex control algorithms, guaranteeing the accuracy and constancy of the dosage ratio from the fundamental mechanical structure.

[0016] This invention employs an integrated design, combining the metering, proportioning control, and mixing functions of multiple reagents into a single compact device. The swashplate and rocker plate mechanisms in the circulation assembly drive all piston sleeves to move in strict synchronization, ensuring the consistency of the timing of the intake and discharge actions in each passage. This provides a stable time reference for proportioning control. Simultaneously, the impeller in the discharge mechanism rotates synchronously with the drive shaft, enabling the proportionally discharged reagents to be thoroughly mixed in the discharge pipe in real time. This avoids the problem of uneven mixing of reagents in external pipelines, simplifies the system piping, and improves the immediacy and stability of the treatment effect.

[0017] This invention has excellent environmental adaptability and ease of maintenance. Its purely mechanical control mechanism is not sensitive to humidity, corrosive gases or electromagnetic interference in the working environment, making it particularly suitable for long-term stable operation in harsh industrial wastewater treatment sites. The ratio setting is completed through mechanical adjustment, and once set, it is not easy to drift, reducing the tediousness of daily calibration. At the same time, the device has a clear structure, and the main moving parts are easy to disassemble and maintain, significantly reducing the use and maintenance costs throughout the entire life cycle.

[0018] This invention ensures precise dosage while allowing for flexible adjustment of the dosage. By changing the speed of the drive motor, the reciprocating frequency of the piston sleeve can be linearly adjusted, thereby simultaneously changing the total dosage of all chemicals while maintaining a fixed ratio. This enables the device to quickly adapt to changes in water volume during the wastewater treatment process, achieving dynamic optimization of treatment effect and operational economy.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0024] Please see Figures 1 to 8 To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The core of this embodiment is to achieve independent, precise and proportional control of the inhalation volume of multiple drugs through a set of purely mechanical linkage mechanisms, and to complete the premixing inside the device, which fundamentally solves the technical problem of relying on independent pumps and valves in traditional methods and making it difficult to guarantee long-term accurate proportions.

[0025] The integrated drug dispensing device provided in this embodiment mainly includes a dispensing mechanism and a dispensing mechanism 41. The dispensing mechanism is the core for achieving precise metering and inhalation of multiple drugs in proportion, and it further integrates multiple sets of adjustment components 11, a shared circulation component 21, and a unidirectional component 31 to ensure correct flow direction. The dispensing mechanism 41 is responsible for instantly mixing the proportionally metered multiple drugs and finally dispensing them.

[0026] 1. Overall Structure of the Distribution Agencies The dispensing mechanism revolves around a core power unit (circulation component 21), which is designed to allow multiple sets of regulating components 11 to work in parallel, each set independently responsible for the precise metering of a specific agent.

[0027] 1.1 Adjustment Component 11: Drug Proportion Setting Unit Each set of adjustment components 11 corresponds to a type of agent, used to set and adjust the proportion of that agent in the total dosage.

[0028] Flow control valve body: The main body of the assembly includes a right-angle tube 12. One end of the right-angle tube 12 is connected to an inner sleeve 13. A control tube 14 is coaxially sleeved outside the inner sleeve 13, with its inner diameter larger than the outer diameter of the inner sleeve 13, forming an annular cavity. A sealing sleeve 15 is slidably installed in this annular cavity and can fit tightly against the end face of the inner sleeve 13, acting as a shut-off valve.

[0029] Proportional adjustment mechanism: An adjusting sleeve 16 is threaded onto the outer wall of the control pipe 14. A push rod 17 is coaxially mounted inside the adjusting sleeve 16, and the front end of the push rod 17 is connected to the sealing sleeve 15 via an adjusting spring 18. By rotating the adjusting sleeve 16, the depth to which the push rod 17 extends into the control pipe 14 can be changed, thereby linearly adjusting the preload force of the adjusting spring 18 acting on the sealing sleeve 15. The magnitude of this preload force directly determines the minimum pressure required to open the valve in this circuit, and is a key parameter for setting the discharge rate of the agent. A vertical pipe 19 is connected to the side wall of the control pipe 14 as a channel for agent discharge.

[0030] 1.2 Circulation Component 21: Power and Metering Execution Unit The circulation component 21 provides uniform inhalation and exhalation power to all regulating components 11 and ensures that each drug is synchronously metered according to a preset ratio in each cycle.

[0031] Multi-cylinder volumetric pump: A volumetric sleeve 22 serves as the main body, with multiple independent fixed chambers 23 distributed at equal angles along the circumference inside. Each fixed chamber 23 corresponds to a set of adjusting components 11. A piston sleeve 24 is sealed and slidably installed inside each fixed chamber 23. The top of the piston sleeve 24 is connected to the top of the volumetric sleeve 22 via a return spring 25.

[0032] Internal pressure buffer mechanism for the piston: Each piston sleeve 24 has an internal spring 26, the lower end of which is connected to a follower disc 27. The follower disc 27 can slide and seal within the piston sleeve 24. A follower sleeve 28 is threadedly connected to the bottom of the piston sleeve 24. When there is no external pressure, the follower disc 27 adheres to the follower sleeve 28 under the action of the internal spring 26, forming a temporary seal.

[0033] Cam Drive System: A drive shaft 29 coaxially passes through a volumetric sleeve 22 and is driven by a motor 46. A swashplate 210 is fixed on the drive shaft 29. The bottom surface of the swashplate 210 contacts a rocker plate 212 via multiple rolling balls 211. The bottom surface of the rocker plate 212 contacts the central ball 213 at the top of each piston sleeve 24. Thus, the continuous rotation of the drive shaft 29, through the switching between the swashplate 210 and the rocker plate 212, drives all piston sleeves 24 to perform strictly synchronized reciprocating linear motion within their respective fixed cavities 23.

[0034] 1.3 Unidirectional component 31: Flow direction control unit The one-way component 31 ensures unidirectional flow of the pharmaceutical fluid, preventing mixing or backflow.

[0035] On both the upstream and downstream sides of each right-angle tube 12, a feed tube 33 is threadedly connected via an intermediate sleeve 32 (in actual use, one side is selected according to the flow direction). Each intermediate sleeve 32 contains a one-way spring 34, the end of which abuts against a one-way ball 35. Under the action of the spring force, the one-way ball 35 abuts against the port of the feed tube 33 to form a one-way seal, allowing fluid to flow only from the feed tube 33 to the right-angle tube 12, and cutting off the flow in the opposite direction.

[0036] 2. Discharge mechanism 41: Mixing and discharge unit The discharge mechanism 41 receives the medicine discharged from each regulating component 11 in proportion and mixes it in real time.

[0037] All the vertical pipes 19 of the adjusting components 11 converge into a discharge pipe 42. An impeller 43 with multiple through holes 44 is installed inside the discharge pipe 42. The impeller 43 is connected to and rotates with the drive shaft 29. A motor 46 is mounted on the outside of the volumetric sleeve 22 via a fixing sleeve 45, driving the entire system.

[0038] 3. Working principle and process of the device S1: Initialization and scaling settings.

[0039] According to the types and proportions of chemicals required by the wastewater treatment process, each chemical storage tank is connected to the inlet pipe 33 of the corresponding regulating component 11. For each chemical, the preload force of the regulating spring 18 acting on the sealing sleeve 15 is precisely set by rotating its corresponding regulating sleeve 16. This preload force value Fs is a function of the required chemical volume ratio and is usually determined through calibration. After completion, the motor 46 is started.

[0040] S2: Synchronized proportional inhalation phase.

[0041] Motor 46 drives transmission shaft 29 to rotate, and through the transmission of swashplate 210 and rocking plate 212, piston sleeve 24 begins to move upward synchronously (return stroke).

[0042] During the upward stroke of each piston sleeve 24, the volume of its corresponding fixed cavity 23 increases, generating negative pressure inside.

[0043] This negative pressure is transmitted to the corresponding right-angle tube 12 and feed tube 33. The negative pressure overcomes the elastic force of the one-way spring 34, drawing the one-way ball 35 away from the port of the feed tube 33, and the drug is drawn in.

[0044] At the same time, negative pressure also acts on the sealing sleeve 15, the internal spring 26 is in a relaxed state (the follower plate 27 is in contact with the follower sleeve 28), and the sealing sleeve 15 remains closed. Therefore, at this stage, each fixed cavity 23 only completes the quantitative inhalation of its own drug, the inhalation volume is determined by the stroke of the piston sleeve 24, and the stroke of each cavity is consistent.

[0045] S3: Pressure comparison and sequential discharge stage.

[0046] After the piston sleeve 24 reaches the top dead center, it begins to move downwards (working stroke) under the drive of the swashplate. At this time, the pressure in each fixed cavity 23 begins to rise.

[0047] The pressure initially acts on the follower disc 27, compressing the internal spring 26. During this process, because the one-way ball 35 has been reset and closed, the medicine cannot return to the storage tank, and the sealing sleeve 15 remains closed due to the preload of the adjusting spring 18, preventing the medicine from being discharged. Therefore, the initial pressure is mainly used to compress the internal spring 26, and the reaction force Fin of the internal spring 26 increases linearly.

[0048] Key trigger point: When the piston sleeve 24 descends to a certain position, the force Fin generated by the compressed internal spring 26 increases to equal the preload force Fs of the preset adjusting spring 18 of the pipeline, that is, Fin = Fs.

[0049] Proportional Discharge: At this point, the sealing sleeve 15 opens. From this moment until the piston sleeve 24 reaches its bottom dead center, the medication in the fixed cavity 23 will be discharged through the opened sealing sleeve 15 and vertical pipe 19 to the discharge pipe 42. For pipelines with a larger preload Fs setting, the sealing sleeve 15 requires a longer piston stroke to accumulate enough Fin before it can open, resulting in a shorter effective discharge stroke and a smaller discharged dosage. Conversely, for pipelines with a smaller Fs setting, the effective discharge stroke is longer, and a larger discharged dosage is achieved. By setting different Fs for different medications, their discharge volume ratio in each cycle can be precisely controlled.

[0050] S4: Internal mixing and final discharge.

[0051] All the proportioned chemicals are collected in the discharge pipe 42. The impeller 43, which rotates synchronously with the drive shaft 29, strongly shears and agitates the collected chemical fluid, ensuring that it is fully premixed before flowing out of the device. The fully mixed chemicals are finally discharged from the lower end of the discharge pipe 42 and directly enter the wastewater treatment process.

[0052] S5: Cyclic reset.

[0053] After the piston sleeve 24 reaches the bottom dead center, it begins to move upward again. At this time, the sealing sleeves 15 of each pipeline close rapidly under the action of pressure difference and adjusting spring 18. As the piston sleeve 24 moves upward, the pressure in the fixed cavity 23 decreases, and the internal spring 26 gradually returns to its original position until the follower plate 27 re-fits the follower sleeve 28. The system returns to the initial state of S2, ready to begin the next precise proportioning and dosing cycle.

[0054] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
