Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an automatic dosing system based on dynamic water quality feedback. Background Technology

[0002] Water treatment is a crucial step in many fields, including industrial production, environmental protection, and aquaculture. This process typically involves adding specific types of chemical agents, such as flocculants, disinfectants, or pH adjusters, to the water to purify it or regulate its physicochemical properties.

[0003] In traditional water treatment operations, the addition of chemicals largely relies on manual operation. Operators estimate the dosage based on experience, which is not only labor-intensive but also difficult to guarantee inaccurate measurement, often resulting in overdosing or underdosing. Overdosing leads to chemical waste and may cause secondary pollution; while underdosing results in substandard water treatment effects, affecting the normal operation of subsequent processes.

[0004] To overcome the drawbacks of manual dosing, some semi-automatic devices using timed and metered pumps have emerged on the market. While these devices improve the regularity of dosing to some extent, their dosing logic is usually a preset, fixed pattern. However, in practical applications, the water quality of the water to be treated, such as turbidity, pollutant concentration, and pH, is often dynamically changing. Fixed dosing patterns cannot adaptively adjust to real-time fluctuations in water quality, thus their accuracy remains limited, making it difficult to achieve optimal use of chemicals while ensuring treatment effectiveness.

[0005] Furthermore, the agent needs to be thoroughly mixed with the water after addition to achieve maximum effectiveness. Existing mixing devices mostly use a motor to directly drive the agitator to rotate in the water. This design means that the motor and other electrical components are in a humid or even submerged environment for a long time, making them prone to failure due to moisture and corrosion. This not only results in poor equipment reliability and high maintenance costs, but also poses safety hazards such as electrical leakage.

[0006] Therefore, this invention proposes an automatic dosing system based on dynamic water quality feedback to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems existing in the water treatment dosing device, such as the inability to accurately and dynamically adjust the dosage according to real-time water quality, low degree of automation, complex structure of the stirring device, and poor operational reliability, this utility model aims to provide an automatic dosing system based on dynamic water quality feedback with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an automatic water dosing system based on dynamic water quality feedback, including: a support frame, a water storage tank, a dosing mechanism, an agitation mechanism, a sensor, and a controller.

[0009] The dosing mechanism includes a feeding box for holding the reagent and a weighing plate for detecting the weight of the reagent in the feeding box; the stirring mechanism includes a U-shaped frame and a stirring cylinder rotatably mounted on the U-shaped frame.

[0010] Furthermore, the sensor, weighing plate, dosing mechanism, and agitation mechanism are all electrically connected to the controller. The controller controls the dosing mechanism to perform quantitative dosing based on the water quality signal detected by the sensor and the weight signal fed back by the weighing plate, and controls the U-shaped frame of the agitation mechanism to move back and forth in the water storage tank so as to drive the agitation drum to rotate and stir using the water resistance.

[0011] Preferably, the feeding mechanism further includes a storage bin, a discharge port located at the bottom of the storage bin, a baffle plate for opening or closing the discharge port, and a telescopic rod for driving the baffle plate.

[0012] Preferably, the top of the storage box is provided with a feed box, and the inside of the storage box is provided with a guide plate above the discharge port for guiding the medicine.

[0013] Preferably, the feeding mechanism further includes a cross plate for mounting the telescopic rod and the baffle plate.

[0014] Preferably, the feeding mechanism also includes a motor and a rotating plate for tilting the feeding box, the motor being controlled by a controller.

[0015] Preferably, the agitation mechanism further includes at least one telescopic rod II that drives the U-shaped frame to reciprocate, and the telescopic rod II is controlled by a controller.

[0016] Preferably, the inner wall of the water storage tank is provided with a sliding groove, and the two ends of the U-shaped frame are provided with sliders that slide in cooperation with the sliding groove.

[0017] Preferably, the U-shaped frame is provided with a fixing rod, and the stirring cylinder is rotatably fitted onto the outer periphery of the fixing rod.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up a water quality sensor, a controller, and a dosing mechanism with a weighing plate, constructs a closed-loop control system with dynamic feedback, which solves the problems of existing technologies where the dosing of chemicals relies on manual experience, has inaccurate measurement, and cannot be adjusted according to dynamic changes in water quality. It achieves the technical effect of automatically and accurately adding the required chemicals according to real-time water quality, significantly improves the level of intelligence and treatment effect of water treatment, and effectively saves chemical costs.

[0019] 2. This utility model solves the problems of existing stirring devices that often use underwater motors for driving, resulting in complex structures, easy corrosion and damage, and safety hazards. It achieves the technical effect of using water resistance to make the stirring drum rotate spontaneously for stirring. This ingenious structural design avoids placing electrical components in water, significantly simplifies the equipment structure, reduces the failure rate and maintenance costs, and improves the reliability and safety of operation.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an automatic dosing system based on dynamic water quality feedback, which aims to solve the problems of existing water treatment dosing devices, such as the inability to accurately and dynamically adjust the dosage according to real-time water quality, low automation, and uneven mixing of reagents.

[0024] like Figure 1 and Figure 2 As shown, the automatic dosing system based on dynamic water quality feedback includes a support frame 4 and a water tank 1 fixed on the support frame 4. The water tank 1 is used to contain the water to be treated and serves as a mounting carrier for other components. The system also includes a dosing mechanism 2 installed above the water tank 1, an agitation mechanism 3 installed inside the water tank 1, a sensor 6 installed inside the water tank 1 for detecting water quality, and a controller 5 electrically connected to the sensor 6, the dosing mechanism 2, and the agitation mechanism 3 respectively. The controller 5 is used to receive the water quality signal detected by the sensor 6 and control the operation of the dosing mechanism 2 and the agitation mechanism 3 based on the water quality signal. At the same time, the controller 5 is also adapted to receive the weight signal fed back by the dosing mechanism 2 to achieve precise quantitative dosing of the agent, thereby forming a closed-loop automatic control process based on dynamic water quality feedback.

[0025] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structural cooperation and connection relationship between the dosing mechanism 2 and the stirring mechanism 3. Please refer to the following for details. Figure 2 and Figure 3 The structure of the dosing mechanism 2 will be described in detail below: The dispensing mechanism 2, as a component for achieving precise automatic dispensing, specifically includes a storage tank 201 for storing the reagent. A feed hopper 202 for convenient feeding is fixedly connected to the top of the storage tank 201, and a discharge port 204 is opened at its bottom. To control the falling of the reagent, the dispensing mechanism 2 also includes a horizontal plate 203. A telescopic rod 206 is fixedly installed on the horizontal plate 203. A baffle plate 207 is connected to the telescopic end of the telescopic rod 206. The baffle plate 207 is slidably disposed at the discharge port 204 to open and close the discharge port 204. Simultaneously, a [missing information - likely a device or component] is fixedly installed inside the storage tank 201 above the discharge port 204. Below the discharge port 204, on the guide plate 205 that guides the medicine, there is a feeding box 210 for receiving and weighing the medicine. The feeding box 210 is fixed on the weighing plate 211, and the weighing plate 211 feeds back the real-time weight signal to the controller 5. In order to realize the pouring of the medicine, the feeding mechanism 2 is also equipped with a motor 208. The output shaft of the motor 208 is fixedly connected to the rotating plate 209, and the weighing plate 211 carrying the feeding box 210 is fixed on the rotating plate 209. Thus, the motor 208 can drive the rotating plate 209 to rotate, thereby causing the feeding box 210 to flip so that the quantitative medicine inside can be poured into the water storage tank 1.

[0026] Based on the above embodiments, the stirring mechanism 3 of this utility model also adopts a preferred technical solution to ensure that the agent and water can be mixed quickly and evenly. Please refer to the following for details. Figure 2 and Figure 4 The detailed structure of the stirring mechanism 3 is explained below: The stirring mechanism 3 is integrally installed inside the water storage tank 1. It includes a U-shaped frame 302. To drive the U-shaped frame 302 to achieve reciprocating linear motion within the water storage tank 1, the stirring mechanism 3 also includes at least one telescopic rod 301. One end of the telescopic rod 301 is fixedly connected to the inner wall of the water storage tank 1, while its telescopic end is hinged or fixedly connected to the U-shaped frame 302. In a preferred embodiment, two telescopic rods 301 are symmetrically arranged on the inner walls at both the front and rear ends of the water storage tank 1, jointly driving the movement of the U-shaped frame 302. To ensure the U-shaped frame 302 moves smoothly... To ensure the stability of the U-shaped frame 302 during reciprocating motion, grooves 306 are provided on the inner walls of both sides of the water storage tank 1 along its length. Sliding blocks 305 are fixedly connected to both ends of the U-shaped frame 302, and sliding connections are formed between the sliding blocks 305 and the grooves 306. A fixed rod 303 is also fixedly connected between the two arms of the U-shaped frame 302. The stirring cylinder 304 is rotatably fitted around the outer periphery of the fixed rod 303. When the U-shaped frame 302 is driven to move, the fixed rod 303 moves accordingly, thereby driving the stirring cylinder 304 to travel through the water.

[0027] Working principle: When using this equipment, the water to be treated is first delivered to the water storage tank 1. At this time, the sensor 6 inside the water storage tank 1 detects the water and sends the water quality detection feedback to the controller 5. At this time, the telescopic rod 206 at the bottom of the horizontal plate 203 retracts backward, causing the baffle plate 207 to move backward, allowing the cleaning agent in the storage tank 201 to fall into the feeding tank 210 through the discharge port 204 via the guide plate 205. At this time, the weighing plate 211 weighs the discharged material and sends the weight feedback to the controller 5. When the required dosage is reached, the telescopic rod 206 pushes the baffle plate 207 backward. The forward movement stops the material from being fed, while the motor 208 drives the rotating plate 209 to rotate, causing the top opening of the feeding box 210 to face downwards so that the cleaning agent inside is poured into the water. At the same time, when the cleaning agent reacts with the water, the telescopic rods 301 on the front and rear sides inside the water storage tank 1 push the U-shaped frame 302 to move back and forth inside the water storage tank 1. The slider 305 slides inside the slide groove 306 to prevent the U-shaped frame 302 from shaking. At the same time, the fixed rod 303 moves back and forth in the water, and under the action of resistance, it causes the stirring cylinder 304 to stir in the water to accelerate the dissolution and mixing of the cleaning agent.
