Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, specifically to a flocculant formulation screening system. Background Technology
[0002] Flocculants are polymeric substances primarily used in water treatment processes. They work by adsorbing and bridging suspended particles to aggregate and form flocs, thus accelerating particle sedimentation and achieving solid-liquid separation. The theoretical basis of flocculants is the "agglomeration" theory. This theory involves positively (or negatively) charged groups and negatively (or positively) charged, difficult-to-separate particles in water approaching each other, lowering their potential and making them unstable. The particles then aggregate using their polymerization properties and are separated through physical or chemical methods. Flocculants are mainly used in water supply and wastewater treatment.
[0003] Different proportions of flocculants are required for different water supplies or wastewater. The common method of formula screening is to complete the process one experiment at a time. This requires repeated experiments, which consumes more experimental materials, equipment and manpower, thus increasing the total cost of the experiment. Moreover, repeated experiments take up a lot of time, which reduces the efficiency of the entire formula screening process, makes it impossible to obtain the corresponding results quickly, and delays the progress of subsequent work. Summary of the Invention
[0004] To solve the above technical problems, this utility model provides a highly efficient flocculant formulation screening system.
[0005] The technical solution is as follows: A flocculant formulation screening system, the key points of which are: it includes a hollow box, a water storage tank is set in the upper part of the box, the water storage tank is equipped with a first turbidity sensor, a preparation area and a reaction area are set below the water storage tank, the preparation area includes at least two preparation cups, the reaction area includes at least eight reaction cups, water outlet pipes are arranged at the bottom of the water storage tank in the same number as the reaction cups, each water outlet pipe is respectively set directly above the corresponding reaction cup, a flipping rod is set between the water storage tank and the reaction area, one end of the flipping rod extends out of the box and is connected to a flipping motor, a dosing cylinder is fixed on the flipping rod in the same number as the reaction cups, and the dosing cylinder is set above the corresponding reaction cup; each preparation cup and at least four dosing cylinders are respectively provided with an output pipe, the liquid outlet of each output pipe is located directly above the corresponding dosing cylinder, and each reaction cup is correspondingly provided with a second turbidity sensor. With the above structure, the raw water in the storage tank and the flocculant solution in the preparation area can enter the reaction zone. The proportion of the solution added in different reaction cups is different, which can simultaneously realize the reaction of flocculants with raw water in multiple proportions. The turbidity value of the liquid is detected by a turbidity sensor, thereby adjusting the proportion. The flocculant formulation screening time is shorter and the efficiency is higher.
[0006] Preferably, the preparation area comprises two preparation cups. A first magnetic stirrer is installed at the bottom of the preparation area, and the preparation cups are placed on the first magnetic stirrer, each equipped with corresponding magnetic stirring particles. A pipe connecting the two preparation cups to external tap water is installed directly above them, and a solenoid valve is installed on the pipe. A third level gauge is installed in each preparation cup. With this structure, external tap water can enter the preparation cups in the preparation area, and the third level gauge can detect the internal liquid level. After water inflow, the prepared flocculant solution is added to the preparation cups, and the first magnetic stirrer initiates the stirring reaction.
[0007] Preferably, a first electric push rod is provided behind the first magnetic stirrer, and a corresponding ultrasonic disruptor is provided on the crossbar of the first electric push rod corresponding to the preparation cup, with the probe of the ultrasonic disruptor extending into the preparation cup. With this structure, the ultrasonic disruptor promotes the mixing or reaction between the reagent and tap water. The first electric push rod can control the raising and lowering of the ultrasonic disruptor, lowering it during use and raising it when not in use, thus preventing the probe of the ultrasonic disruptor from being immersed in the liquid for extended periods and causing damage.
[0008] Preferably, the reaction zone contains eight reaction cups. The water storage tank is connected to an external raw water tank. Eight water outlet pipes are installed at the bottom of the water storage tank corresponding to the reaction cups, with the outlet ends of the pipes facing the mouth of the reaction cups. Solenoid valves are installed on all the water outlet pipes. A first level gauge is also installed inside the water storage tank. With this structure, the water storage tank can monitor the water level through the first level gauge, and controlling the opening and closing of the solenoid valves on the outlet pipes allows water from the storage tank to flow into the corresponding reaction cups.
[0009] Preferably, the flipping motor at the extended end of the flipping rod is fixed to the outer wall of the housing, and the middle part of the dosing cylinder is clamped on the flipping rod. The number and position of the dosing cylinder correspond one-to-one with the reaction cup. With the above structure, the liquid in the dosing cylinder can be accurately poured into the reaction cup through the flipping mechanism for the next reaction step.
[0010] Preferably, a peristaltic pump is installed on the output pipe, with eight peristaltic pumps corresponding to the number of dosing cylinders. The suction ends of the pipes connected to the first four peristaltic pumps extend into one preparation cup, and the suction ends of the pipes connected to the latter four extend into another preparation cup. The discharge ends of the pipes connected to the peristaltic pumps are directly opposite the opening of the un-inverted dosing cylinder. With this structure, the peristaltic pump is simple in design, highly adaptable, and can accurately and stably deliver the prepared drug solution from the preparation cup to the reaction cup.
[0011] Preferably, a second magnetic stirrer is provided below the reaction zone, the reaction cup is placed on the second magnetic stirrer, and stirring particles and a second level gauge are provided in the corresponding reaction cup;
[0012] A second electric push rod is installed behind the second magnetic stirrer, and eight second turbidity sensors are installed on the crossbar of the second electric push rod corresponding to the reaction cup. With the above structure, the chemical solution poured into the reaction cup from the dosing cylinder can react with the raw water, and the reaction is accelerated by stirring with the second magnetic stirrer. After the reaction, the turbidity value of the supernatant in the reaction cup is measured by the second turbidity sensors.
[0013] Beneficial Effects: The core of this invention lies in utilizing coagulation and stirring experiments to accurately determine the optimal concentration and dosage of flocculants by simulating production processes, thus providing scientific and accurate data references for actual production. It solves two major problems: First, traditional waterworks rely heavily on manual experience for coagulant dosing, resulting in significant uncertainty and error; second, while smart waterworks pursue intelligence, their intelligent dosing systems often rely solely on post-feedback adjustment based on sediment turbidity, lacking prior data support. Furthermore, this invention features a simple structure and ease of use. By adding different amounts of reagents to the reaction cup in the reaction zone, it rapidly screens flocculant formulations. Multiple reactions occur simultaneously, resulting in shorter flocculant formulation screening time and higher efficiency, making it suitable for water supply and wastewater treatment to achieve water purification. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0015] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0016] like Figure 1 As shown, a flocculant formulation screening system includes a hollow box 8. A water storage tank 1 is located at the upper part of the box 8. A first turbidity sensor 1a is installed inside the water storage tank 1. A preparation zone 2 and a reaction zone 3 are located below the water storage tank 1. The preparation zone 2 includes at least two preparation cups 2d, and the reaction zone 3 includes at least eight reaction cups 3d. Water outlet pipes, matching the number of reaction cups 3d, are arranged at the bottom of the water storage tank 1, with each outlet pipe positioned directly above a corresponding reaction cup 3d. A flipping rod 4c is provided between the water tank 1 and the reaction zone 3. One end of the flipping rod 4c extends out of the tank body 8 and is connected to the flipping motor 4b. A dosing cylinder 4a, the same number as the reaction cups 3d, is fixed on the flipping rod 4c and is positioned above the corresponding reaction cup 3d. Each preparation cup 2d is provided with an output pipe for at least four dosing cylinders 4a. The liquid outlet of each output pipe is located directly above the corresponding dosing cylinder 4a. Each reaction cup 3d is provided with a second turbidity sensor 3a.
[0017] The inlet of the water storage tank 1 is connected to the raw water tank, and a raw water pump is installed on the raw water pipeline. Raw water can be pumped into the water storage tank 1 by self-priming. A first level gauge 1b is installed inside the water storage tank 1. When the liquid level reaches the designated position, the addition of raw water is stopped. A water outlet pipe is opened at the bottom of the water storage tank 1 corresponding to the reaction zone 3. The outlet end of the water outlet pipe is directly opposite the mouth of the reaction cup 3d. A solenoid valve is installed on all the water outlet pipes. The first turbidity sensor 1a is installed at the top of the water storage tank 1 and can measure the turbidity of the raw water. After the value stabilizes and the response time ends, the raw water turbidity data is uploaded and saved. Even if the liquid level drops and the turbidity cannot be measured later, the data is still saved in the database.
[0018] The preparation area 2 contains two preparation cups 2d, each with a capacity of 200ml. The water inlet pipes of both preparation cups 2d are connected to an external tap water pipe, and a solenoid valve is installed on each pipe. A third level gauge 2b is installed inside each preparation cup 2d. The third level gauge 2b is a non-contact level sensor positioned at the 100ml level. When water is introduced, the corresponding switch on the control panel is activated, opening the solenoid valve to allow water inflow. When the third level sensor 2b detects that the level has been reached, the corresponding switch is closed.
[0019] A first magnetic stirrer 5 is installed at the bottom of the preparation area 2. The preparation cup 2d is placed on the first magnetic stirrer 5, and magnetic stirring particles are correspondingly installed inside the preparation cup 2d. A first electric push rod 2a is installed behind the first magnetic stirrer 5. An ultrasonic disruptor 2c is installed on the crossbar of the first electric push rod 2a corresponding to the preparation cup 2d. The probe of the ultrasonic disruptor 2c extends into the preparation cup 2d. After tap water is added, the prepared reagent is poured into the 200ml preparation cup 2d. After a certain period of time, the first magnetic stirrer 5 is automatically started and stirred according to the set time and speed. At the same time, the first electric push rod 2a is started, and the ultrasonic disruptor 2c is lowered to the corresponding position below the liquid surface of the preparation cup 2d. The ultrasonic disruptor 2c is started to work. When the stirring time of the first magnetic stirrer 5 is over, the first magnetic stirrer 5 and the ultrasonic disruptor 2c are automatically stopped. After standing for a period of time, the liquid surface in the preparation cup 2d is calm.
[0020] The flipping motor 4b at the extended end of the flipping rod 4c is fixed on the outer wall of the equipment housing 8 on the side away from the control panel. The middle part of the dosing cylinder 4a is clamped on the flipping rod 4c. The number and position of the dosing cylinder 4a correspond one-to-one with the reaction cup 3d. The capacity of the dosing cylinder 4a is 30ml. When flipped, the opening end of the dosing cylinder 4a is directly opposite the opening end of the reaction cup 3d, which can ensure that the liquid in the eight dosing cylinders 4a is added to the reaction cup 3d at the same time. After all the liquid in the dosing cylinders 4a has been poured out, the dosing cylinder 4a is flipped to its original position.
[0021] A peristaltic pump 7 is installed on the output pipe. The number of peristaltic pumps 7 corresponds to the number of dosing cylinders 4a, and there are also eight of them. The suction end of the pipe connected to the first four peristaltic pumps 7 extends into a preparation cup 2d, and the suction end of the pipe connected to the last four extends into another preparation cup 2d. The discharge end of the pipe connected to the peristaltic pump 7 is directly opposite the opening of the dosing cylinder 4a that has not been turned over. During the process of the ultrasonic crusher 2c descending, the inlet of its peristaltic pump 7 also descends to the corresponding position below the liquid surface of the preparation cup 2d.
[0022] After the liquid in the preparation cup 2d has been left to stand for a period of time, the feeding program of the eight 30ml dosing cylinders 4a is automatically started. According to the pre-set feeding amount of each dosing cylinder 4a, the peristaltic pump 7 injects the corresponding amount of medicine into the eight dosing cylinders 4a respectively. After the eight dosing cylinders 4a have been filled with medicine, the corresponding peristaltic pump 7 is stopped. After all the dosing is completed, the peristaltic pump 7 is paused and the first electric push rod 2a is started again to raise the ultrasonic breaker 2c to a certain position to avoid the probe of the ultrasonic breaker 2c being immersed in the liquid for a long time and causing damage.
[0023] A second magnetic stirrer 6 is installed below the reaction zone 3. The reaction cups 3d are placed on the second magnetic stirrer 6, and corresponding stirring particles and second level gauges 3b are installed on each reaction cup 3d. The capacity of the reaction cup 3d is 1.5L. The second level gauge 3b is a contact level sensor, positioned at the 1L liquid level. When the second level sensor 3b detects that there is no water in the reaction cup 3d, it activates the corresponding switch to start water intake. The water entering the reaction cups 3d is raw water. Once all eight reaction cups 3d have reached their corresponding liquid levels, the water intake program automatically shuts off. After water intake is complete, the chemical solution is added through the dosing cylinder 4a. After dosing, the second magnetic stirrer 6 is activated, and stirring is performed according to the pre-set magnetic stirring pump time and segmented speed. After stirring, allow the liquid in reaction vessel 3d to settle for a period of time. A second electric push rod 3c is installed behind the second magnetic stirrer 6. Eight second turbidity sensors 3a are installed on the crossbar of the second electric push rod 3c corresponding to the reaction vessel 3d. After a certain time, the second electric push rod 3c is automatically activated, lowering the eight second turbidity sensors 3a simultaneously to the corresponding positions below the liquid surface in reaction vessel 3d where the supernatant can be measured. After reaching the positions, wait for a period of time to measure the turbidity of the supernatant in reaction vessel 3d. After the turbidity measurement value is saved, the second electric push rod 3c is activated again to raise the second turbidity sensors 3a back to their original positions.
[0024] By comparing the turbidity data in the first turbidity sensor 1a and the second turbidity sensor 3a, the most suitable flocculant formulation can be screened. The system can also test eight different proportions of flocculant formulations at the same time, which can obtain the corresponding formulation more quickly and efficiently, save time, reduce the trouble of multiple experiments, and reduce the burden of manual testing.
[0025] The system is used as follows: A certain amount of raw water is added to the water storage tank 1. The turbidity of the raw water is measured by the first turbidity sensor 1a. Raw water is added to the reaction cup 3d through the bottom water outlet pipe. A certain amount of tap water and the prepared drug solution are added to the preparation cup 2d. The tap water and drug solution are mixed or reacted evenly by the first magnetic stirrer 5 and the ultrasonic crusher 2c. After the reaction is completed, the mixture is left to stand for a period of time. Different amounts of drug solution are added to different dosing cylinders 4a by the peristaltic pump 7. During the liquid addition process, the ultrasonic crusher 2c of the peristaltic pump 7 is moved out of the preparation cup 2d. After the drug solution is added, it is added to the reaction cup 3d by the flipping mechanism 4. The mixture is stirred evenly and reacted for a period of time. The turbidity value is measured by the second turbidity sensor 3a, thereby screening out the optimal flocculant formula.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
