Description

Technical Field

[0001] The invention relates to the technical field of circulating water modification, in particular to an automatic dosing system applied to circulating water modification treatment. Background Art

[0002] Circulating water modification and treatment is an important part of industrial water treatment. It aims to improve the operating efficiency of the circulating water system, extend equipment life and reduce operating costs by optimizing water quality, controlling corrosion, and inhibiting scaling and microbial growth. Common problems in circulating water systems include the formation of carbonate or sulfate deposits by calcium and magnesium ions in the water, which reduces heat transfer efficiency; electrochemical corrosion of metal pipes and equipment caused by dissolved oxygen and chloride ions; the reproduction of bacteria and algae to form biological slime, which blocks pipes and aggravates corrosion; and the deposition of silt and particulate matter that obstructs water flow.

[0003] The corresponding treatment method is to add chemical agents, including corrosion inhibitors, scale inhibitors, and bactericides and algaecides, based on physical interception. At the same time, the chemical addition treatment needs to be combined with water quality characteristics, system operating conditions and environmental protection requirements, and efficient management can be achieved through scientific drug selection, precise addition and dynamic monitoring.

[0004] For example, the patent publication number CN114768572B, "A circulating water dosing device and method," is to inject water and dosing drugs in equal proportions by setting up relevant components. However, considering that there are many types of drugs to be added to the circulating water for improvement, when compound drugs are added, it is not possible to meet the circulating water treatment requirements by discharging drugs at a single outlet of the drug inlet pipe.

[0005] To this end, for example, the patented "circulating water dosing device" with publication number CN219232235U is configured to selectively add multiple groups of reagents by setting up multiple groups of rotating drug storage columns, and adjusting the compatibility of the reagents, similar to organic phosphoric acid + polycarboxylic acid, taking into account both corrosion inhibition and scale inhibition, to achieve efficient treatment of circulating water. However, the rotating disk rotating drug application operation makes the corresponding reagent addition adjustment method complicated, and the shaking mixing method is not suitable for excessive addition of circulating water.

[0006] Therefore, we propose an automatic dosing system for circulating water modification and treatment. Summary of the Invention

[0007] The purpose of the present invention is to provide an automatic dosing system for circulating water modification treatment to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: an automatic dosing system for circulating water reforming treatment, comprising a dosing tank, a mixing cylinder fixedly connected to the inner wall of the dosing tank, and a quantitative drug discharging mechanism installed on the top of the mixing cylinder;

[0009] The quantitative drug discharge mechanism includes a drug storage cartridge and a sliding sealing column. The inner wall of the drug dosing tank is movably connected to the drug storage cartridge, a liquid separation cavity is provided in the drug storage cartridge, and a liquid discharge port is provided on the inner wall of the liquid separation cavity. The inner wall of the drug storage cartridge is slidably connected to the sliding sealing column, and the outer wall of the sliding sealing column is evenly provided with a connecting groove group.

[0010] The bottom of the sliding sealing column passes through the medicine storage cartridge and is movably connected to a movable block 1 through a bearing. A rotating shaft is installed in the dosing tank. One end of the rotating shaft respectively passes through the connecting groove group and the movable block 1 and is movably connected to the inner wall of the bottom of the dosing tank. The outer wall of the rotating shaft is symmetrically connected to a stirring rod for rotation. One end of the stirring rod is movably connected to a cross bar. The side wall of the cross bar is fixedly connected to a counterweight ball by welding. One end of the stirring rod is movably connected to the outer wall of the movable block 1 through a connecting rod.

[0011] Furthermore, the connecting groove group is arranged at four locations on the outer wall of the sliding sealing column. The connecting groove group on the outer wall of the sliding sealing column is distributed in a spiral manner, and the angle between the centers of two adjacent connecting grooves is 90°. The connecting groove group is arranged corresponding to the upper drainage port of the liquid separation chamber.

[0012] Furthermore, a driving assembly is fixed to the top of the dosing tank by bolts, the output end of the driving assembly is fixed to the end of the rotating shaft, a detector is installed on the top of the dosing tank, and the end of the detector passes through the dosing tank and extends into the mixing barrel.

[0013] Furthermore, a rotary sleeve is installed on the top of the dosing tank, and a rotary column inside the rotary sleeve passes through the top of the dosing tank and is sleeved with a gear. The outer wall of the drug storage cartridge is provided with teeth that are meshed and connected with the gear on the rotary column. A dosing cover is installed on the dosing port on the top of the dosing tank.

[0014] Furthermore, a movable block 2 and a sealing sleeve are installed in the dosing tank and on the rotating shaft. The groove on the outer wall of the sealing sleeve is engaged with the inner wall of the dosing tank. The sealing sleeve is movably connected to the movable block 2. The end of the connecting rod on the stirring rod is movably connected to the outer wall of the movable block 2. A spring is installed on the outer wall of the rotating shaft, and one side of the spring is in contact with the sealing sleeve.

[0015] Furthermore, the bottom of the dosing tank is connected to a drain pipe, and valve one and valve two are respectively installed on the drain pipe.

[0016] Furthermore, a liquid inlet is provided on the outer wall of the dosing tank, a heating component is installed on the outer wall of the dosing tank, and a heating rod of the heating component extends to the bottom of the mixing barrel.

[0017] The automatic dosing method for the circulating water modification treatment is:

[0018] Variable speed selective automatic dosing: open the dosing cover on the top of the dosing tank, turn the top rotary sleeve and store the corrosion inhibitor, scale inhibitor, bactericide and algaecide and pH regulator in each liquid chamber of the storage cartridge in turn. Adjust the speed of the drive component according to the required chemicals to be added to the circulating water to be treated;

[0019] The speed of the drive assembly is set to gear 1. At this time, the rotating shaft rotates and the sliding sealing column is pulled downward by the expansion of the stirring rod, causing the connecting groove group on the outer wall of the sliding sealing column to coincide with the drainage port on the inner wall of the single-side liquid separation chamber. If there is corrosion inhibitor in the liquid separation chamber at this time, the corrosion inhibitor will automatically flow into the mixing barrel. Along with the circulating water continuously discharged from the liquid inlet, the reagent and the circulating water are stirred and mixed in the mixing barrel;

[0020] If scale inhibitors need to be added, the shaft speed is increased, the expansion angle of the stirring rod increases, and the lowering distance of the entire sliding sealing column increases, causing the upper discharge port of the corresponding liquid separation chamber to be connected with the corresponding connecting groove group, completing the automatic addition of the corresponding agent, and the subsequent addition method of other agents is the same as above;

[0021] Set the dosing stirring time, and after the stirring time is over, the drive component automatically shuts down, the stirring rod is retracted to pull the sealing sleeve up, and the circulating water is automatically discharged through the notch on the sealing sleeve and finally discharged along the drain pipe.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, simple and efficient speed adjustment is used as the core of automatic dosing control. The swing angle change of the stirring rod during speed adjustment is utilized to actively control the movement of the sliding sealing column at the bottom of the drug storage cartridge, and the connecting groove group on its outer wall coincides with the upper discharge port of the liquid separation chamber storing different drugs, thereby completing selective automatic drug delivery. At the same time, when the rotating shaft rotates, the expanded stirring rod and cross bar stir the dosing circulating water, accelerating the mixing of the drugs and the circulating water. At the same time, the driving component stops working, and as the stirring rod contracts, the sealing sleeve at the bottom of the mixing cartridge is automatically pulled up, so that the notch on the sealing sleeve is connected to the mixing cartridge, completing automatic liquid discharge.

[0024] The automatically rotating and adjustable medicine storage cartridge facilitates the selective addition of subsequent medicines. At the same time, the heating component heats up the circulating water, further improving the reaction efficiency between the medicine and the circulating water. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-8 , the present invention provides a technical solution:

[0036] Example 1: Figure 1 As shown, according to the circulating water treatment capacity, multiple groups of dosing tanks 1 are installed, and the circulating water is discharged from the liquid inlet 2 side into the mixing cylinder 5 in the dosing tank 1, accompanied by the selective addition of multiple reagents to achieve high-speed mixing of the reagents and the circulating water;

[0037] like Figure 2 As shown, a quantitative drug discharging mechanism 6 is installed on the top of the mixing cylinder 5 in the dosing tank 1, and the drug storage cylinder 601 is as shown in FIG. Figure 4As shown, four liquid chambers 602 are provided inside, which are filled according to the reagents required for circulating water treatment. The compatibility of various circulating water treatment reagents is taken into consideration to avoid chemical reactions and failures between different reagents. At the same time, a liquid discharge port 603 is provided on the inner wall of the drug storage cartridge 601, and a sliding sealing column 604 is slidably engaged with the central axis of the drug storage cartridge 601.

[0038] like Figure 5 As shown, the outer wall of the entire sliding sealing column 604 is evenly provided with a connecting groove group 605, and the connecting groove group 605 is spirally distributed and gradually increases in height. The angle between the centers of two adjacent connecting grooves is 90 degrees. Figure 6 As shown, the connecting groove group 605 is marked as four slots A, B, C and D, among which the connecting groove A is at the lowest position, and the four connecting grooves correspond to the four liquid separation chambers 602 respectively. If the corrosion inhibitor, scale inhibitor, bactericide and algaecide and pH adjuster are filled in each liquid separation chamber 602 at this time, if the drugs in the corresponding liquid separation chamber 602 need to be discharged, it is necessary to control the height of the entire sliding sealing column 604 relative to the drug storage cartridge 601 so that the connecting groove group 605 on the sliding sealing column 604 coincides with the drainage port 603 in each liquid separation chamber 602;

[0039] For example, if the connecting groove A is filled with corrosion inhibitor in the liquid separation chamber 602, as the sliding sealing column 604 descends, the connecting groove A on the sliding sealing column 604 begins to overlap with the drain port 603, and the corrosion inhibitor in the liquid separation chamber 602 flows down into the mixing cylinder 5 through the overlapping groove position of the two.

[0040] When scale inhibitor needs to be added to the mixing cylinder 5, the liquid separation chamber 602 corresponding to the scale inhibitor is perpendicular to the connecting groove B, and the connecting groove B is at the top of the connecting groove A. It is necessary to control the sliding sealing column 604 to descend. As the sliding sealing column 604 moves downward, the connecting groove A and the drain port 603 overlap first, and the corrosion inhibitor is discharged first. As the sliding sealing column 604 moves rapidly, the sliding sealing column 604 gradually moves downward, causing the connecting groove B to contact the drain port 603, and the connecting groove A is now separated from the drain port 603 and automatically closed.

[0041] At this point, the scale inhibitor begins to be automatically discharged. Similarly, by controlling the downward distance of the sliding sealing column 604, the connecting grooves C and D can be made to coincide with the upper discharge ports 603 of each liquid separation chamber 602, completing the discharge operation of the bactericidal algaecide and pH regulator in other liquid separation chambers 602.

[0042] The entire sliding sealing column 604 is controlled to slide on the inner wall of the drug storage cartridge 601. A rotating shaft 4 is movably connected to the inner side of the drug storage cartridge 601, and the end of the rotating shaft 4 is connected to the driving assembly 3. Figure 2 and Figure 3As shown, the rotating shaft 4 is located at the bottom center of the drug storage barrel 601 and is symmetrically connected to the stirring rod 7. The end of the stirring rod 7 is movably connected to the cross bar 8, and a counterweight ball 9 is fixed inside the cross bar 8. As the rotating shaft 4 rotates, the centrifugal force generated drives the stirring rod 7 on the rotating shaft 4 to expand, and cooperates with the holes between the stirring rods 7 to stir the circulating water and the drug in the mixing barrel 5, thereby accelerating the mixing of the drug in the circulating water;

[0043] like Figure 7 As shown, a connecting rod is movably provided at the top of the stirring rod 7, and a movable block 13 is sleeved on the rotating shaft 4. The connecting rod at the end of the stirring rod 7 is movably connected to the outer wall of the movable block 13, and the movable block 13 is movably connected to the bottom of the sliding sealing column 604. As the rotating shaft 4 rotates, the unfolded stirring rod 7 pulls down the sliding sealing column 604 through the connecting rod, which also enables the sliding sealing column 604 to slide at the bottom of the drug storage cartridge 601, completing the overlap of the connecting groove group 605 on the sliding sealing column 604 with the various drainage ports 603, and automatically dispensing the drug. The height adjustment of the entire sliding sealing column 604 is adjusted by the rotation speed of the rotating shaft 4. When the rotation speed of the rotating shaft 4 increases, the rotation fluctuation angle of the stirring rod 7 increases, and the relative rotation amplitude increases to achieve continuous movement of the sliding sealing column 604, and the descending distance is increased.

[0044] To this end, the rotation gear of the rotating shaft 4 is set to match the downward movement distance of the sliding sealing column 604. For example, when the rotation speed of the rotating shaft 4 is controlled at 40-60 rpm, the rotation angle of the stirring rod 7 and the downward movement distance of the sliding sealing column 604 enable the communication groove A to be connected with the drainage port 603. When the rotation speed is controlled at 65-75 rpm, the communication groove B is overlapped with the drainage port 603.

[0045] Similarly, when the circulating water is automatically dosing chemicals, the matching data of the rotation speed of the shaft 4 and the descending distance of the sliding sealing column 604 are first obtained and stored in the external controller. When a specific chemical or compound chemical needs to be added to the circulating water, the rotation speed of the shaft 4 can be adjusted by the controller. Compared with setting up an additional dosing device, the automatic addition of chemicals by speed control is simple to control and easy to operate.

[0046] For replenishing the medicine in each liquid chamber 602 in the medicine storage cartridge 601, a rotary sleeve 10 is provided on the top of the medicine adding tank 1. Figure 2 As shown, the bottom rod of the selection sleeve extends into the dosing tank 1 and is sleeved with a fixed gear, and the storage cartridge 601 is movably connected to the dosing tank 1. The top of the dosing tank 1 is provided with a dosing port and a dosing cover 11 is installed on the side. By opening the dosing cover 11 and rotating the rotary sleeve 10, the storage cartridge 601 in the dosing tank 1 is driven to rotate. At this time, the operator can add the corresponding medicine to the rotatable storage cartridge 601.

[0047] At the same time, a detector 12 is also installed on the top of the dosing tank 1. The detector 12 extends into the mixing drum 5 to detect the pH value, water temperature and other data of the circulating water discharged. In order to accelerate the reaction between the circulating water and the relevant reagents, a heating component 17 is also installed in the dosing tank 1 at the bottom of the mixing drum 5. The bottom of the mixing drum 5 is heated by heat conduction. With the continuous addition of circulating water from the liquid inlet 2 and the synchronous entry of the corresponding reagents, the stirring rod 7 is used for circulatory stirring to complete the full reaction of the circulating water and the reagents. Finally, the circulating water is automatically discharged through the drain pipe 18 at the bottom of the dosing tank 1. When discharging, valve 19 and valve 2 20 are actively opened;

[0048] In addition, online fluorescent tracing technology is used to achieve real-time monitoring of the concentration of chemical agents added to the water system, and the sliding sealing column 604 in the storage barrel is replaced as needed, and the sliding sealing columns 604 corresponding to the connecting groove groups 605 of different depths are installed to increase the dosage of the agent.

[0049] Example 2: Due to the influence of the movement of the circulating water, the stirring rod 7 will deflect when rotating, causing the sliding sealing column 604 to fluctuate up and down. Therefore, when draining, the connecting groove group 605 and the drainage port 603 are controlled to overlap as much as possible, so that the influence of the movement of the sliding sealing column 604 on the discharge of the reagent is reduced;

[0050] At the same time Figure 8 As shown, the side wall of the stirring rod 7 at the bottom is also movably connected to a movable block 2 14 through a connecting rod, and the movable block 2 14 is movably connected to the sealing sleeve 15 connected to the bottom outlet side of the mixing barrel 5. As the stirring rod 7 rotates and fluctuates, the connecting rod pulls the movable block 2 14 upward, and the corresponding sealing sleeve 15 rises synchronously. The notch on the side wall of the sealing sleeve 15 rises and contacts the inner wall of the mixing barrel 5 and automatically closes. As the circulating water and the reagent mix, the sealing sleeve 15 is sealed and cannot be discharged.

[0051] When the rotation speed of the rotating shaft 4 decreases, the sealing sleeve 15 is pushed down by the stirring rod 7 to realize the connection between the notch and the entire mixing drum 5. The circulating water after the dosing is automatically discharged from the gap of the notch, completing the automatic discharge of the circulating water and facilitating the movement of the sealing sleeve 15. A spring 16 is also provided on the rotating shaft 4. Through the movement control of the sealing sleeve 15, the reagent in the mixing drum 5 and the circulating water are fully mixed, avoiding the problem of direct discharge of some untreated circulating water, and the overall uniformity of the circulating water treatment is high.
