[0001] This utility model relates to the field of circulating water dosing and detection technology, specifically, to a sampling and detection device for circulating water dosing. Background Technology
[0002] In the daily operation of laboratories, the treatment of circulating water is a crucial task. Currently, some laboratories still use the traditional manual pouring method when adding chemicals to circulating water. This method has many drawbacks. Firstly, manual pouring is cumbersome and requires a significant amount of manpower and time. Staff need to accurately measure, move, and carefully pour the chemicals into the circulating water system; the entire process is not only inefficient but also prone to errors. Secondly, when chemicals are added to the circulating water, they react chemically, potentially releasing harmful gases or volatile substances. If laboratory staff accidentally inhale these substances, it can seriously harm their health, potentially causing respiratory illnesses, allergic reactions, or even more serious health problems. Therefore, existing methods of adding chemicals to circulating water urgently need improvement to enhance operational convenience and safety. Utility Model Content

[0043] Reference Figures 1-8 This first embodiment of the present invention proposes a sampling and testing dosing device for a circulating water system, comprising: a tank body 100 having a dosing channel 110; a first switch 200 rotatably mounted on the tank body 100, which opens or closes the dosing channel 110 after rotation; a second switch 300 movably mounted on the tank body 100, which opens or closes the dosing channel 110 after movement; after the first switch 300 opens the dosing channel 110, the second switch 300 closes the dosing channel 110; and a buffer channel 210 between the first switch 200 and the second switch 300 for storing materials.
[0044] In this embodiment, the first switch 200 is rotatably mounted on the tank 100. The first switch 200 employs a rotary design. When medication needs to be added, the operator can rotate the first switch 200 to open the medication addition channel 110, allowing the medication to enter the tank 100 through the channel. To prevent splashing after the medication reacts with the liquid in the tank 100, and to prevent medication leakage or the entry of external impurities, a second switch 300 is designed. When sampling is required, the operator first opens the second switch 300, simultaneously closing the first switch 200, and adds the medication into the buffer channel 210 formed between the first and second switches. Due to the obstruction of the first switch 200, the medication and the liquid in the tank 100 will not react, thus preventing splashing or accidental inhalation of unhealthy gases. After medication addition is complete, the second switch 300 is closed while the first switch 200 is opened, allowing the medication to enter the tank 100 for reaction. The design of the buffer channel 210 ensures the smoothness and safety of medication addition and sampling operations. The dosing device in this embodiment can adapt to the dosing and sampling needs of different circulating water systems, which not only optimizes the operator's operating experience, but also ensures the accuracy of sampling and the precision of dosing.
[0045] Furthermore, the first switch 200 includes: a plurality of rotating members 220, which are rotatably disposed on the barrel 100 and arranged sequentially along the circumference in the dosing channel 110. After the rotating members 220 rotate to a horizontal state, the dosing channel 110 is closed.
[0046] In this embodiment, several rotating components 220 are arranged circumferentially inside the dosing channel 110. After the rotating components 220 rotate simultaneously to a horizontal position, they come into contact with each other, closing the dosing channel 110. After the rotating components 220 rotate simultaneously in the opposite direction to a vertical position, the dosing channel 110 is fully opened. When adding the medicine, it is not necessary to completely rotate the rotating components 220 to a horizontal position; the dosing channel 110 can be slightly opened. When adding the medicine, some of the medicine can flow into the tank 100. Since the rotating components 220 are arranged at an angle at this time, the odor and mixture after the medicine reacts with the liquid in the tank 100 will not be directly discharged from the dosing channel 110.
[0047] Furthermore, the rotating component 220 includes: a rotating shaft 221, which is rotatably mounted on the barrel 100, with one end of the rotating shaft 221 located inside the dosing channel 110 and the other end located outside the dosing channel 110; and a baffle 222, which is mounted on the rotating shaft 221. When the rotating shaft 221 rotates clockwise, it drives the baffle 222 to close the dosing channel 110.
[0048] In this embodiment, to enable the dosing channel 110 to open or close after the rotating component 220 rotates, a rotating shaft 221 is rotatably mounted on the tank body 100, with one end located inside the dosing channel 110 and the other end located outside the dosing channel 110. The rotating shaft 221 provides a rotation center for the baffle 222, ensuring that the baffle 222 can rotate within the dosing channel 110. The baffle 222 is mounted on the rotating shaft 221 and rotates with the rotation of the rotating shaft 221. When the rotating shaft 221 rotates clockwise, it drives the baffle 222 to rotate to a horizontal position, closing the dosing channel 110. When the rotating shaft 221 rotates counterclockwise, it drives the baffle 222 to rotate to a vertical position, opening the dosing channel 110.
[0049] Specific operation: When it is necessary to close the dosing channel 110, the operator can rotate each shaft 221 clockwise, causing the baffle 222 to rotate to a horizontal position. At this time, several baffles 222 completely seal the dosing channel 110, ensuring that the drug cannot pass through. The operator rotates each shaft 221 clockwise, causing the baffle 222 to rotate from a vertical position to a horizontal position. The horizontal part of the baffle 222 will completely cover the dosing channel 110, achieving closure. When adding the drug, it is not necessary to completely rotate the rotating part 220 to a horizontal position, but to slightly open the dosing channel 110. At this time, the baffle 222 is in an inclined position, and the drug can flow into the tank 100. Since the baffle 222 is arranged at an incline at this time, the odor and mixture generated after the drug reacts with the liquid in the tank 100 will not be directly discharged from the dosing channel 110, thereby reducing the diffusion of odor and liquid leakage.
[0050] Furthermore, it also includes: a first connecting rod 223, one end of which is disposed on the other end of the rotating shaft 221; a second connecting rod 224, one end of which is disposed on the other end of the first connecting rod 223, the second connecting rod 224 is arranged in a vertical direction, and after the second connecting rod 224 descends, it drives the first connecting rod 223 to rotate clockwise.
[0051] In this embodiment, one end of the first connecting rod 223 is disposed on the other end of the rotating shaft 221. The function of the first connecting rod 223 is to convert the vertical movement of the second connecting rod 224 into the rotational movement of the rotating shaft 221. The second connecting rod 224 can move up and down vertically. When the second connecting rod 224 descends, it drives the first connecting rod 223 to rotate clockwise, thereby driving the rotating shaft 221 and the baffle 222 to rotate, closing the dosing channel 110. The specific steps are as follows: When it is necessary to close the dosing channel 110, the operator can push the second connecting rod 224 downward. The descent of the second connecting rod 224 drives the first connecting rod 223 to rotate clockwise, thereby driving the rotating shaft 221 and the baffle 222 to rotate to a horizontal state, closing the dosing channel 110. When medication needs to be added, the operator can push the second linkage 224 upward. The rise of the second linkage 224 causes the first linkage 223 to rotate counterclockwise, which in turn causes the rotating shaft 221 and the baffle 222 to rotate to a vertical position, opening the medication addition channel 110. Through the design of multiple rotating parts 220 of the first switch 200, the operator can easily open and close the medication addition channel 110, achieving efficient medication addition. The design of the buffer channel 210 ensures that the medication can smoothly enter the tank 100 while preventing medication leakage or the entry of external impurities.
[0052] Furthermore, it also includes: a lifting component 400, which is lifted and installed on the barrel body 100 and sleeved outside the dosing channel 110; one end of the second connecting rod 224 is hinged to the other end of the first connecting rod 223, and the other end of the second connecting rod 224 is hinged to the lifting component 400; after the lifting component 400 descends, it drives the second connecting rod 224 to descend.
[0053] In this embodiment, the descent of the lifting component 400 causes the second connecting rod 224 to descend. When it is necessary to close the dosing channel 110, the operator can push the lifting component 400 downwards. The descent of the lifting component 400 causes the second connecting rod 224 to descend. To facilitate operation and reduce manpower, the operator can place a small bucket containing the medicine on the lifting component 400, which can both lower the lifting component 400 and reduce manpower. The design of the lifting component 400 further simplifies the operation process; the operator only needs to control the up and down movement of the lifting component 400 to open and close the second switch 300.
[0054] Furthermore, the first switch 200 includes: two slide plates 310, which are slidably mounted on the tank 100 in opposite directions, and the dosing channel 110 is closed when the two slide plates 310 come close to each other; two third connecting rods 320, each having a first end 321 and a second end 322, the first end 321 being rotatably mounted on the slide plate 310 and the second end 322 being rotatably mounted on the tank 100; and two fourth connecting rods 330, one end of which is rotatably mounted on the slide plate 310 and the other end of which is rotatably mounted on the tank 100, the third connecting rods 320 and the fourth connecting rods 330 being arranged in parallel, and the other end of each of the two fourth connecting rods 330 having teeth 331, which mesh with each other. The third link 320 also has a control end 323, and a second end 322 is located between the control end 323 and the first end 321. The lifting member 400 has a first guide slope 410, which abuts against one of the control ends 323. After the lifting member 400 descends, the first guide slope 410 causes the control end 323 to swing clockwise. After the control end 323 swings, it causes the two sliding plates to move away from each other. The lifting member 400 also has a second guide slope 420, which abuts against another control end 323. After the lifting member 400 rises, the second guide slope 420 causes the control end 323 to swing counterclockwise. After the control end 323 swings, it causes the two sliding plates 310 to move away from each other.
[0055] In this embodiment, the first switch 200 is an opening and closing mechanism. Two sliding plates 310 are arranged in opposite directions on the tank 100. When the two sliding plates 310 approach each other, the dosing channel 110 is closed; when they move away from each other, the dosing channel 110 is opened. Two third connecting rods 320 are present, each having a first end 321 and a second end 322. The first end 321 is rotatably mounted on the sliding plate 310, and the second end 322 is rotatably mounted on the tank 100. The function of the third connecting rods 320 is to convert the vertical movement of the lifting member 400 into the sliding movement of the sliding plate 310. The control end 323 allows the movement of the sliding plate 310 to be controlled by the vertical movement of the lifting member 400. The lifting member 400 is mounted on the tank 100 and sleeved outside the dosing channel 110, and has a first guide slope 410. The first guide ramp 410 abuts against a control end 323. The descent of the lifting component 400 causes the control end 323 to swing clockwise. After the control end 323 swings, it causes the two sliding plates to move away from each other. When it is necessary to add medicine, the operator can push the lifting component 400 downward, and the first guide ramp 410 abuts against the control end 323, causing the control end 323 to swing clockwise. The swing of the control end 323, through the linkage of the third link 320 and the fourth link 330, causes the two sliding plates 310 to move away from each other, opening the medicine adding channel 110. At the same time, the second link 224 descends, and the second switch 300 closes or slightly opens. The second guide ramp 420 contacts another control end 323. After the dosing is completed, an elastic element can be designed between the lifting component 400 and the tank 100. After the operator leaves, the elastic element rebounds, the lifting component 400 rises, and the second guide ramp 420 squeezes the other control end 323. The other control end 323 swings counterclockwise. After the control end 323 swings, it drives the two slide plates 310 to move closer to each other, thereby closing the dosing channel 110. After the lifting component 400 rises, it drives the second connecting rod 224 to swing counterclockwise, opening the second switch 300. The agent completely enters the tank 100 from the buffer channel 210.
[0056] Furthermore, the lifting component 400 has a through hole 430, one end of which is sleeved outside the dosing channel 110, and the other end of which has a guide surface 440 leading to the dosing channel 110.
[0057] In this embodiment, in order to seal the lifting component 400 and the dosing channel 110 and enable the agent to accurately enter the dosing channel 110, a guide surface 440 is designed on the other end of the through hole 430. Due to the design of the guide surface 440, the diameter of one end of the through hole 430 is larger than the diameter of the other end. The diameter difference between one end and the other end of the through hole 430 can enable one end to be fitted outside the dosing channel 110 and the other end to lead to the dosing channel 110.
[0058] Furthermore, the barrel 100 also has a dosing port 120, and also includes a cover 500 with threads provided at the dosing port 120.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
