Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of laboratory equipment, specifically to an acid tank with visible acid value in a laboratory. Background Technology
[0002] In the process of conducting biochemical experiments, it is necessary to detect the content of trace elements in the sample. At this time, it is necessary to ensure the cleanliness of the glassware used in the detection experiment to avoid the presence of impurities affecting the detection results.
[0003] Therefore, before the experiment, the glassware needs to be acid-soaked to ensure its cleanliness and avoid contamination from the glass itself, which could lead to low accuracy of the experimental results. The current method for acid soaking involves immersing the glassware in a laboratory acid tank. This involves the experimenter wearing gloves manually placing the glassware into the tank until it is completely submerged, and then manually removing it after a period of time. Because acid is highly corrosive, the gloves will be in direct contact with the acid during use. Prolonged contact can easily damage the gloves due to the strong corrosiveness. If the gloves are damaged, the experimenter's hands will be burned by the acid, which is very inconvenient.
[0004] Secondly, since the acid solution in the acid tank needs to be frequently used to soak the vessels, water droplets or residual acid will remain on the inner wall of the vessels. During the soaking process, these substances will affect the acid solution in the acid tank, making it impossible to determine the acid concentration and pH value. This results in poor soaking effect, failing to meet the requirements of experimental soaking, and causing errors in the results of subsequent experiments. Utility Model Content
[0005] This invention provides an acid tank with visible acid value in the laboratory to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model provides an acid tank for visually representing laboratory acid values, comprising:
[0007] The acid tank has a cavity for holding the acid solution.
[0008] A placement cylinder has a fixed handle and an extension cylinder, the extension cylinder having a placement cavity for placing a vessel, the fixed handle being installed on the outer peripheral wall of the extension cylinder, and the extension cylinder having a through hole;
[0009] When the placement cylinder is placed into the receiving cavity, and the fixed handle abuts against the outer wall of the acid cylinder, the insertion cylinder enters the receiving cavity and acid-soaks the vessel in the placement cavity through the through hole.
[0010] Preferably, there are two fixed handles, the maximum distance between the two fixed handles is denoted as a, and the maximum diameter of the accommodating cavity is denoted as b, satisfying the relationship a > b.
[0011] Preferably, the top of the acid cylinder has a placement position, the receiving cavity is located between two of the placement positions, and the placement position abuts against the fixed handle to limit the insertion cylinder from further penetrating into the receiving cavity.
[0012] Preferably, the placement cylinder also has an inner handle, which is installed on the inner peripheral wall of the placement cavity and is located close to the fixed handle.
[0013] Preferably, the depth of the placement cavity is denoted as c, and the depth of the receiving cavity is denoted as d, satisfying the relationship 0.8d < c < d.
[0014] Preferably, a clearance cavity is formed between the bottom of the placement cylinder and the bottom wall of the receiving cavity;
[0015] The laboratory-visible acid tank also includes:
[0016] A concentration detector is installed inside the clearance cavity.
[0017] Preferably, the acid tank with visible laboratory acid value further includes:
[0018] The detection panel is electrically connected to the concentration detector.
[0019] Preferably, the through hole is formed on the peripheral wall and bottom wall of the cylinder.
[0020] Preferably, the surfaces of the acid tank and the placement tank are coated with an acid-resistant coating.
[0021] Preferably, the acid tank has an inlet and an outlet, both of which are connected to the accommodating cavity;
[0022] The laboratory-visible acid tank also includes:
[0023] The cover body is fitted with the cylinder head that extends into it.
[0024] The laboratory acid tank with visible acid value proposed in this invention has the following beneficial effects:
[0025] The laboratory acid tank with visible acid value proposed in this utility model allows the operator to lift the placement tank and slowly place the placement tank containing the vessel into the acid tank during use. When the fixed handle abuts against the upper edge of the acid tank, the insertion tank just enters the acid solution. The acid solution flows into the placement cavity through the through hole and fully contacts the vessel, thereby completing the acid soaking treatment of the vessel. After the treatment is completed, the operator can lift the placement tank as a whole to avoid direct contact with the acid solution.
[0026] Experimenters do not need to put their hands into the acid tank, avoiding direct contact between the acid and gloves, reducing the risk of burns caused by glove corrosion and damage. The fixed handle is matched with the upper edge of the acid tank to prevent the tank from slipping or sinking completely into the acid, improving the controllability and safety of the operation.
[0027] The placement tank allows for full flow of acid through the through-hole, enabling the acid to enter the placement chamber from multiple directions and immerse the vessel in it from all angles. This improves the uniformity and effectiveness of the cleaning process and effectively avoids the problem of dead spots caused by poor acid flow in certain areas, thereby enhancing the quality of the laboratory vessel treatment.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0040] This utility model provides an acid tank 100 for laboratory visual acid value, comprising:
[0041] Acid tank 110 has a receiving cavity 110a for holding acid liquid;
[0042] The placement cylinder 120 has a fixed handle 121 and an extension cylinder 122. The extension cylinder 122 has a placement cavity 122a for placing a vessel. The fixed handle 121 is installed on the outer peripheral wall of the extension cylinder 122. The extension cylinder 122 has a through hole 122b.
[0043] When the placement cylinder 120 is placed into the accommodating cavity 110a, and the fixed handle 121 abuts against the outer wall of the acid cylinder 110, the insertion cylinder 122 enters the accommodating cavity 110a and acid-soaks the vessel in the placement cavity 122a through the through hole 122b.
[0044] Please refer to Figures 1-2 In this embodiment, the interior of the cylinder 122 is configured as a placement cavity 122a for placing experimental vessels to be acid-soaked.
[0045] During use, the operator lifts the placement tank 120 and slowly lowers the placement tank 120 containing the vessel into the acid tank 110. When the fixed handle 121 abuts against the upper edge of the acid tank 110, the insertion tank 122 just enters the acid solution. The acid solution flows into the placement cavity 122a through the through hole 122b and fully contacts the vessel, thus completing the acid soaking treatment of the vessel. After the treatment is completed, the operator can lift the placement tank 120 out as a whole to avoid direct contact with the acid solution.
[0046] Experimenters do not need to put their hands into the acid tank 110, avoiding direct contact between the acid and gloves, reducing the risk of burns caused by glove corrosion and damage. The fixed handle 121 is matched with the upper edge of the acid tank 110 to prevent the tank 120 from slipping or sinking completely into the acid, thus improving the controllability and safety of the operation.
[0047] The placement tank 120 allows for full flow of acid through the through hole 122b, enabling the acid to enter the placement chamber 122a from multiple directions and form an all-round immersion with the vessel, improving the uniformity and effectiveness of the cleaning process, effectively avoiding the problem of immersion dead zones caused by local acid blockage, thereby improving the quality of experimental vessel treatment.
[0048] The detachable placement tank 120 structure allows the entire tank to be removed for rinsing or replacement of vessels after treatment, eliminating the need to reach into the acid solution to retrieve vessels, significantly improving operational convenience. It also prevents vessels from directly contacting the inner wall of the acid tank 110, reducing cross-contamination.
[0049] It should be noted that the main function of the acid tank 110 is to serve as a container for holding acid. The acid tank 110 is roughly a rectangular shell, and a receiving cavity 110a is provided on the upper end face. The receiving cavity 110a is used to store the acid required for the processing vessel.
[0050] The cylinder 122 is roughly a rectangular shell with a placement cavity 122a on its upper end face, and the handle 121 is roughly rectangular in shape.
[0051] Preferably, there are two fixed handles 121, the maximum distance between the two fixed handles 121 is denoted as a, and the maximum diameter of the accommodating cavity 110a is denoted as b, satisfying the relationship a > b.
[0052] Please refer to Figures 1-2 In this embodiment, when performing acid soaking treatment, the experimenter places the container into the placement tank 120, and then vertically inserts the placement tank 120 into the receiving cavity 110a of the acid tank 110. The insertion tank 122 is submerged in the acid solution, and the fixed handle 121 is suspended outside the opening of the acid tank 110. When the placement tank 120 descends to a certain position, the two fixed handles 121 will abut against the placement position 110b on the upper edge of the acid tank 110. Since a>b, the placement tank 120 cannot continue to sink, which plays a clear limiting role. The placement tank 120 is thus stably suspended at an appropriate depth in the acid solution, avoiding bottom contact or excessive soaking.
[0053] Since the maximum spacing of the fixed handles 121 is greater than the diameter of the accommodating cavity 110a, when the placement cylinder 120 is placed into the acid cylinder 110, its sinking range is limited by the physical structure, and it cannot fall completely into the cylinder, thus avoiding direct contact between the vessel and the bottom of the cylinder, which could cause damage, contamination, or inability to remove the vessel.
[0054] By fixing the handle 121 to the edge of the acid tank 110, the sinking depth of the inserted tank 122 is controlled, thereby precisely controlling the degree of contact between the vessel and the acid solution. This ensures that the acid soaking treatment can completely immerse the vessel without causing cleaning dead spots or damage due to excessive settling.
[0055] Preferably, the top of the acid cylinder 110 has a placement position 110b, the receiving cavity 110a is located between the two placement positions 110b, and the placement position 110b abuts against the fixed handle 121 to restrict the extension cylinder 122 from continuing to extend into the receiving cavity 110a.
[0056] Please refer to Figures 1-2 In this embodiment, when the experimenter slowly and vertically inserts the placement cylinder 120 from above the acid cylinder 110, the part of the placement cylinder 120 extending into the insertion cylinder 122 enters the receiving cavity 110a of the acid cylinder 110, and the vessel begins to gradually immerse in the acid solution. As the sinking depth increases, the fixed handle 121 eventually abuts against the two placement positions 110b at the top of the acid cylinder 110, preventing the insertion cylinder 122 from sinking further, thereby ensuring that the vessel reaches the predetermined acid soaking depth in the receiving cavity 110a, and will not cause problems such as contact with the bottom of the cylinder, breakage, or operational difficulties due to free sinking.
[0057] By setting a fixed placement position 110b as a limiting platform, the depth of the insertion tank 122 into the acid solution can be precisely controlled, so that each container is placed at the same acid bubble height, improving the stability and repeatability of acid bubble treatment and avoiding treatment differences caused by changes in depth.
[0058] Preferably, the placement cylinder 120 further has an inner handle 123, which is installed on the inner peripheral wall of the placement cavity 122a and is located close to the fixed handle 121.
[0059] Please refer to Figures 1-2 In this embodiment, before the experiment begins, the operator grasps the inner handle 123, lifts the placement tank 120 as a whole, and places it into the acid tank 110. Since the inner handle 123 is located near the upper part of the tank body and inside the tank body, the operator can use the inner handle 123 to stably control the movement trajectory of the placement tank 120, making it easy to place it into the acid tank 110 receiving cavity 110a. When the fixed handle 121 abuts against the placement position 110b, the immersion of the vessel inserted into the tank 122 is realized.
[0060] After the acid soaking treatment is completed, the operator grasps the inner handle 123 again to extract the placement tank 120 from the acid solution as a whole, avoiding direct contact with the acid solution throughout the process, and the extraction action is smooth, facilitating safe transfer and subsequent processing.
[0061] Preferably, the depth of the placement cavity 122a is denoted as c, and the depth of the accommodating cavity 110a is denoted as d, satisfying the relationship 0.8d < c < d.
[0062] Please refer to Figures 1-2In this embodiment, the placement cavity 122a(c) is slightly smaller than the depth (d) of the accommodating cavity 110a to ensure that it will not touch the bottom of the acid cylinder 110 when the placement cylinder 120 sinks, but at the same time it is larger than 80% of the depth of the accommodating cavity 110a to ensure that the vessel can be fully immersed in the acid solution when it is acid-soaked in the placement cavity 122a.
[0063] In use, when the operator puts the placement cylinder 120 into the acid cylinder 110 by using the handle, the placement cavity 122a goes deep into the receiving cavity 110a and comes into contact with the acid. However, since its depth is less than that of the receiving cavity 110a, there is still space at the bottom (avoidance cavity 110c) to prevent the placement cylinder 120 from directly contacting the bottom of the acid cylinder 110.
[0064] By ensuring that the depth of the placement cavity 122a is less than that of the receiving cavity 110a, a clearance space can be reserved at the bottom to avoid direct contact between the placement cylinder 120 and the bottom wall of the acid cylinder 110, thereby reducing the risk of vessel breakage or cylinder damage due to collision or impact.
[0065] c>0.8d The placement cavity 122a can penetrate to most of the depth of the receiving cavity 110a, so that the vessel can be basically completely immersed in the acid solution, ensuring that the acid solution fully covers the surface of the vessel and avoiding incomplete cleaning due to the acid solution level being too shallow.
[0066] Preferably, a clearance cavity 110c is formed between the bottom of the placement cylinder 120 and the bottom wall of the receiving cavity 110a;
[0067] The laboratory-visible acid tank 100 also includes:
[0068] The concentration detector 130 is installed inside the clearance cavity 110c.
[0069] Please refer to Figures 1-2 In this embodiment, when the placement tank 120 is inserted into the acid tank 110, its bottom does not directly contact the bottom wall of the acid tank 110. Instead, a space is formed through the clearance cavity 110c. Inside the clearance cavity 110c, a concentration detector 130 is installed. The concentration detector 130 is in direct contact with the acid solution and can monitor the concentration change or pH value of the acid solution in the acid tank 110 in real time. During use, the experimental apparatus is subjected to acid soaking treatment through the placement tank 120. At the same time, the concentration detector 130 continuously senses the state of the acid solution in the clearance cavity 110c. The detection results can be used to provide feedback on whether the acid solution has met the requirements for acid soaking treatment and to indicate whether the acid solution needs to be replaced or replenished.
[0070] Real-time monitoring with a concentration detector 130 allows for precise control of the acid solution's state, ensuring that the equipment is processed within an effective concentration environment and improving the reliability of experimental results.
[0071] Preferably, the laboratory visible acid tank 100 further includes:
[0072] The detection panel 140 is electrically connected to the concentration detector 130.
[0073] Please refer to Figures 1-2 In this embodiment, during the detection process, after the concentration detector 130 collects the acid solution data, it transmits it to the detection panel 140 in the form of electronic signals. The detection panel 140 converts the signals into visual information (such as acid value, pH level, etc.) and displays it on the panel. Experimenters can read the current acid solution concentration at any time without taking samples or touching the acid solution, and determine whether the acid soaking requirements are met or whether the acid solution needs to be replaced.
[0074] Preferably, the through hole 122b is formed on the peripheral wall and bottom wall of the extension cylinder 122.
[0075] Please refer to Figures 1-2 In this embodiment, the insertion cylinder 122 is the lower structure of the placement cylinder 120. When in use, it is inserted into the receiving cavity 110a of the acid cylinder 110 and immersed in acid. Through holes 122b are provided on the peripheral wall (side wall) and bottom wall of the insertion cylinder 122 so that the acid can freely enter and exit the placement cavity 122a. When the placement cylinder 120 is placed into the acid cylinder 110, the acid flows in from different directions (side and bottom) through these through holes 122b to soak the experimental vessels in the placement cavity 122a. During the acid soaking process, the acid can also continuously contact and exchange with the vessels from multiple directions, improving the soaking uniformity. After the treatment is completed, when the placement cylinder 120 is lifted, the acid can be quickly discharged naturally through the through holes 122b, reducing the adhesion of residual liquid.
[0076] By providing through holes 122b on both the peripheral and bottom walls, the acid can flow into the placement cavity 122a from multiple directions, ensuring that the vessel is fully in contact with the acid from top to bottom and inside to outside, avoiding cleaning dead corners, and significantly improving the consistency and reliability of the acid soaking effect.
[0077] The bottom wall through hole 122b can quickly release residual liquid when the placement cylinder 120 is lifted, preventing acid from remaining in the placement cavity 122a, reducing the risk of laboratory personnel coming into contact with residual acid during the replacement of glassware or cleaning, and improving operational safety and cleaning efficiency.
[0078] Preferably, the surfaces of the acid tank 110 and the placement tank 120 are coated with an acid-resistant coating (not shown in the figure).
[0079] Please refer to Figures 1-2In this embodiment, an anti-acid coating is applied to both the inner and outer surfaces of the acid tank 110 and the placement tank 120. The anti-acid coating has good resistance to strong acid corrosion and forms a protective barrier during use, preventing direct contact between the acid liquid and the tank body material. The coating is always in working condition throughout the acid soaking operation, effectively preventing the acid liquid from causing corrosion damage to the container body.
[0080] Preferably, the acid tank 110 has an inlet 110d and an outlet 110e, both of which are connected to the accommodating cavity 110a;
[0081] The laboratory-visible acid tank 100 also includes:
[0082] The cover 150 is closed with the extension cylinder 122.
[0083] Please refer to Figures 1-2 In this embodiment, the acid tank 110 has an inlet 110d and an outlet 110e on its tank body. Both of these ports are connected to the internal accommodating cavity 110a. The inlet 110d can be used to add acid to the acid tank 110, while the outlet 110e can be used to discharge the used acid, so as to realize the replacement, circulation or cleaning of the acid. The operator can add and discharge the acid through these two ports without disassembling the placement tank 120.
[0084] The top of the acid tank 110 is equipped with a cover 150, which is used to form a sealing structure with the inserted cylinder 122. The cover 150 covers the upper part of the inserted cylinder 122 and can effectively block the evaporation of acid liquid and prevent acid mist from leaking out during the acid soaking process.
[0085] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
