Description

Technical Field

[0001] The utility model relates to the technical field of near-infrared diffuse light analysis, in particular to a liquid container used for near-infrared diffuse light analysis. Background Art

[0002] Infrared diffuse light analysis is an important analytical technique that typically requires the use of specialized containers to hold the liquid sample to be tested. For volatile or reactive liquid samples, the container must be well sealed to prevent volatilization or leakage during testing. Furthermore, storage temperature significantly affects the chemical stability, physical state, and infrared spectral characteristics of the liquid sample. Excessively high temperatures can cause sample decomposition, volatilization, or deterioration, while excessively low temperatures can cause the sample to solidify or crystallize, thus affecting infrared spectrum acquisition and analysis.

[0003] Existing containers usually use water bath insulation to store liquid samples to be tested. Specifically, the temperature is controlled by direct contact between the heat-conducting medium and the sample container. Due to the lack of buffering measures, the external heat-conducting medium (such as hot water or ice water) will quickly exchange heat with the sample, causing the temperature of the first part of the sample to change rapidly and exceed the appropriate temperature range. It is difficult to simultaneously and evenly exchange heat with all samples to achieve uniform temperature changes. The sudden temperature change can easily lead to changes in the properties of the sample. Therefore, to address the above problems, a liquid container for near-infrared diffuse light analysis is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a liquid container for near-infrared diffuse light analysis. The liquid container is composed of an outer insulation box and an inner interlayer liquid container, with a heat conduction cavity provided between the two. The temperature of the inner interlayer liquid container is regulated by injecting a liquid medium into the inner interlayer liquid container, thereby controlling the temperature of the liquid sample stored therein. Since the inner interlayer liquid container has a double-layer structure and an oil cavity for injecting heat conduction oil is formed therein, it can buffer external temperature changes. That is, when a heat conduction medium is suddenly injected into the heat conduction cavity, the heat conduction oil will produce a uniform temperature change accordingly, and no local temperature drastic change will occur. Then, the heat conduction oil can be uniformly heat exchanged with the stored liquid sample, so that the temperature of the sample changes uniformly, and the sample properties are not easily changed due to sudden temperature changes. In addition, the stirring mechanism can be turned to stir the internal liquid medium, making the temperature distribution more uniform. This solves the technical problem in the prior art that due to the lack of buffering measures, the injected heat conduction medium will quickly exchange heat with the part of the sample that contacts it first, causing the temperature of the part of the sample to change rapidly and exceed the appropriate temperature range, and the sample properties are easily changed due to sudden temperature changes.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A liquid container for near-infrared diffuse light analysis comprises an outer thermal insulation box with an inner interlayer liquid container provided therein. The outer thermal insulation box and the inner interlayer liquid container are fixedly connected by an anti-detachment connector and enclose a heat conduction cavity formed therebetween for containing a liquid heat conduction medium. The temperature of the inner interlayer liquid container is regulated by injecting the liquid medium into the inner interlayer liquid container, thereby controlling the temperature of the liquid sample stored therein. A stirring mechanism is installed in the outer thermal insulation box to stir the liquid heat conduction medium in the heat conduction cavity to achieve a uniform temperature distribution. The heat insulation box cover is provided on the outer thermal insulation box.

[0007] Among them, the inner interlayer liquid storage box includes an outer heat-conducting box and an inner heat-conducting box, and the above-mentioned two are fixedly connected by connecting bolts, and an oil cavity is formed between the two, in which heat-conducting oil is poured. Since the inner interlayer liquid storage box is a double-layer structure, an oil cavity filled with heat-conducting oil is formed therein, so it can play a buffering role against external temperature changes, that is, when a heat-conducting medium is suddenly injected into the heat-conducting cavity, the heat-conducting oil will produce a uniform temperature change accordingly, and there will be no local temperature drastic change. Then, it can perform uniform heat exchange with the stored liquid sample, so that the temperature of the sample changes evenly, and it is not easy for the sample properties to change due to sudden temperature changes.

[0008] In one possible implementation, the stirring mechanism includes an upper mounting seat and a lower mounting seat fixedly arranged on the inner wall of the outer insulation box, and a rotating shaft connected in rotation is installed on the above two. The above structural form can realize the positioning installation of the rotating shaft, and a stirring plate is fixedly connected to the end of the rotating shaft. When the rotating shaft rotates, it drives the stirring plate to swing, thereby stirring the liquid medium so that the temperature can be evenly distributed. Buffer limit blocks are fixedly arranged on both sides of the bottom of the outer insulation box. This structure can prevent the stirring plate from directly colliding with the outer insulation box and being damaged and bent.

[0009] In one possible implementation, two limiting rings are fixedly provided on the rotating shaft, wherein the upper limiting ring is in rotational contact with the upper mounting seat, and the lower limiting ring is in rotational contact with the lower mounting seat. The limiting rings can limit the up and down movement of the rotating shaft, thereby fixing the height of the stirring plate so that it can work normally. In addition, a twist wheel is fixedly connected to the top end of the rotating shaft, which can facilitate the user to twist the rotating shaft.

[0010] In one possible implementation, a bent support plate that folds inward is fixedly provided on the top of the outer insulation box, and a connecting folded plate that folds outward is fixedly provided on the top of the inner heat-conducting box, wherein the connecting folded plate is overlapped on the bent support plate. The above-mentioned structural form can realize a sealed connection between the outer insulation box and the inner interlayer liquid storage box, thereby preventing leakage of the heat-conducting medium.

[0011] In one possible implementation, the anti-disengagement connector includes two mutually symmetrical threaded half-shafts and a locking wheel, wherein the two threaded half-shafts are respectively fixed on the bending support plate and the connecting folding plate, and the locking wheel is threadedly connected to the two threaded half-shafts. When the inner interlayer liquid storage box is installed on the outer insulation box, the threaded half-shafts are assembled with each other. At this time, tighten the locking wheel to achieve a fixed connection between the inner interlayer liquid storage box and the outer insulation box through the action of thread engagement.

[0012] In one possible implementation, the outer wall of the outer heat-conducting box is fixedly provided with outer heat-conducting fins, and the outer wall of the inner heat-conducting box is fixedly provided with inner heat-conducting fins. The above-mentioned structural form can increase the heat-conducting area and thus improve the heat-conducting efficiency. In addition, the top of the outer heat-conducting box is provided with an installation groove, in which a closed gasket is provided. This structural form can improve the airtightness of the connection between the outer heat-conducting box and the inner heat-conducting box, and can prevent leakage of heat-conducting oil.

[0013] In one possible implementation, the outer insulation box is provided with a liquid filling port on the upper part of one side and a liquid discharge port on the lower part of the other side, and both the liquid filling port and the liquid discharge port are covered with a threaded closing cover. The above structural form provides the necessary structural basis for the injection and discharge of the heat-conducting medium.

[0014] In one possible implementation, a closed clamping edge is fixedly provided on the bent support plate, and the insulation box cover includes a cover plate, and a clamping edge that matches the size of the closed clamping edge is fixedly provided at the edge of its lower end face. Based on the above structure, the clamping action between the closed clamping edge and the clamping edge can realize a sealed connection between the outer insulation box and the insulation box cover, and a closed edge is fixedly provided in the middle of its lower end face. When the insulation box cover is closed, the closed edge can cover the box opening of the inner interlayer liquid box to prevent the sample from leaking.

[0015] In summary, the present invention has the following beneficial technical effects:

[0016] The liquid container is composed of an outer insulation box and an inner interlayer liquid container, with a heat conduction cavity provided between the two. By perfusing a liquid medium into the inner interlayer liquid container, the temperature of the inner interlayer liquid container is regulated, thereby controlling the temperature of the liquid sample stored therein. Since the inner interlayer liquid container has a double-layer structure, an oil cavity for perfusing heat-conducting oil is formed therein, thereby buffering external temperature changes. That is, when a heat-conducting medium is suddenly injected into the heat-conducting cavity, the heat-conducting oil will produce a corresponding uniform temperature change, and no local temperature drastic change will occur. Thus, the heat-conducting oil can evenly exchange heat with the stored liquid sample, so that the temperature of the sample changes evenly, and it is not easy for the sample properties to change due to sudden temperature changes.

[0017] In addition, the stirring mechanism can be turned to stir the internal liquid medium to make the temperature distribution more uniform. When the rotating shaft is turned, the stirring plate will be driven to swing, thereby stirring the liquid medium so that the temperature can be evenly distributed. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The liquid container is composed of an outer insulation box 1 and an inner interlayer liquid box 2, with a heat conduction cavity 4 provided therebetween. The temperature of the inner interlayer liquid box 2 is regulated by injecting liquid medium therein, thereby controlling the temperature of the liquid sample stored therein. Since the inner interlayer liquid box 2 is a double-layer structure, an oil cavity 23 for injecting heat conduction oil is formed therein, so that it can buffer the external temperature changes. That is, when a heat conduction medium is suddenly injected into the heat conduction cavity 4, the heat conduction oil will produce a uniform temperature change accordingly, and there will be no local temperature drastic change.
