Description

Technical Field

[0001] The utility model relates to the technical field of water bath heating devices, in particular to a water bath treatment device for a colorimetric tube. Background Art

[0002] Water bath heating is a common processing method in chemical experiments. Commonly used water baths are composed of a water pool, a heating device, and a temperature control component. Containers such as conical flasks and test tubes containing test solutions are placed in the water pool for heating. However, the water level of ordinary water baths is shallow. For higher colorimetric tubes, the water level of the water bath will be lower than the liquid level of the colorimetric tubes, which is prone to uneven heating and poor heating effect. It is difficult to adapt to the processing of colorimetric tubes and other containers for containing test solutions. In addition, after the water bath heating is completed, it is not convenient to pass running cold water for cooling. If the container is taken out directly at high temperature, it is easy to be scalded by the high temperature. Waiting for cooling in the air will take a long time to cool. Moreover, for some detection items that require light-proof treatment, the existing water bath has no light-proof measures, which is easy to affect the detection results of items affected by light. Therefore, a water bath treatment device for colorimetric tubes is needed. Utility Model Content

[0024] like Figure 1As shown, a water bath treatment device for colorimetric tubes includes a water bath 1 and a colorimetric tube rack 2 that can be placed in a water tank of the water bath 1. The depth of the water tank of the water bath 1 is at least 18 cm. Preferably, the length, width, and height of the water bath 1 are 35*22*22 cm, and the length, width, and height of the water tank of the water bath 1 are 25*18*18 cm. Since the water tank has a sufficient depth, the water level of the water bath is guaranteed to be higher than the liquid level of the colorimetric tube, and the solution in the colorimetric tube is completely immersed in the water bath, which can heat the colorimetric tube in all directions and ensure that the sample solution is heated evenly. A water inlet pipe 11 and a water outlet pipe 12 connected to the water tank are provided on one side of the water bath 1. The water inlet pipe 11 is located at the upper part, and the water outlet pipe 12 is located at the lower part. The water inlet pipe 11 is provided with a first stop valve 111, and the water outlet pipe 12 is provided with a second stop valve 121. By setting the water inlet pipe 11 and the water outlet pipe 12, after the water bath heating treatment is completed, flowing water can be introduced for cooling. A light-proof cover 13 is provided on the top of the water tank of the water bath pot 1. A step groove 131 for supporting the light-proof cover 13 is provided on the top of the water tank of the water bath pot 1. By providing the light-proof cover 13, the colorimetric tube water tank processing process is in a fully surrounded state, with excellent light-proof effect, and can be applied to samples such as urea that require water bath light-proof treatment.

[0025] like Figure 2 As shown, the colorimetric tube rack 2 includes two side plates 21, a bottom plate 22 connected between the two side plates 21, an intermediate plate hole 23 and an upper plate hole 24, the bottom plate 22 is fixedly connected to the side plates 21, at least three slots 211 are provided on the side plates 21 in the vertical direction, and the intermediate plate holes 23 and the upper plate holes 24 can be inserted into any of the slots 211; a clamping mechanism 25 for clamping the colorimetric tubes in the column is provided at each column of placement holes on the upper plate holes 24, and the diameter of the clamping channel of the clamping mechanism 25 is adjustable. By providing at least three slots 211, it is convenient to adjust the positions of the intermediate plate holes 23 and the upper plate holes 24, so that it can be suitable for the placement of colorimetric tubes of various heights, and the diameter of the clamping channel of the clamping mechanism 25 is adjustable, which can be suitable for the clamping of colorimetric tubes of different diameters within a certain range, and the clamping mechanism 25 ensures the stability of the clamping of the colorimetric tubes, and avoids collision during the placement process of the colorimetric tube rack 2.

[0026] like Figure 3 As shown, the clamping mechanism 25 includes two opposite clamping plates 21, and an arc-shaped clamping portion 2511 corresponding to the placement hole of the upper plate hole 24 is provided on the opposite side of each clamping plate 21. The two ends of each clamping plate 21 are movably sleeved outside the guide rod 252, and the first spring 253 is sleeved outside the two ends of the guide rod 252. The two ends of the guide rod 252 are connected to the upper plate hole 24 through the L-shaped seat 254. This structure is convenient for placing a row of colorimetric tubes by opening the two clamping plates 21 and compressing the first spring 253. When the two clamping plates 21 are released, the first spring 253 is reset, and its resilience makes the two clamping plates 21 clamp tightly, so that a row of colorimetric tubes can be clamped and fixed.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, a retractable elastic clip strip 26 is provided on the upper inner wall of the slot 211, and a clip groove 27 matching the elastic clip strip 26 is provided on the middle plate hole 23 and the upper plate hole 24. The elastic clip strip 26 includes a movable clip plate 261 and a second spring 262, and the lower end of the movable clip plate 261 extends out of the slot 211; a plurality of second springs 262 are connected between the movable clip plate 261 and the top wall of the slot 211, and the two ends of the movable clip plate 261 are slidably connected to the side walls of the slot 211, and the movable clip plate 261 can be retracted in the cavity of the top wall of the slot 211, and the end of the movable clip plate 261 is a rounded structure. This structure facilitates clamping of the middle plate hole 23 and the upper plate hole 24. When the middle plate hole 23 or the upper plate hole 24 is inserted into the slot 211, the movable clamping plate 261 is a rounded structure and is subjected to an upward force, causing the movable clamping plate 261 to shrink. When the middle plate hole 23 or the upper plate hole 24 is inserted, the second spring 262 is reset, and the movable clamping plate 261 is clamped into the clamping slot 27, thereby ensuring the stability of the insertion of the middle plate hole 23 or the upper plate hole 24.

[0028] like Figure 2 As shown, the tops of the two side panels 21 are provided with handle panels 212 extending inwards. The handles facilitate operators to take and place the colorimetric tube rack 2.

[0029] When in use, the use process of the utility model is:

[0030] Determine the insertion position of the middle plate hole 23 or the upper plate hole 24 according to the height of the colorimetric tube, and place the colorimetric tube containing the solution into the placement holes of the upper plate hole and the middle plate hole in turn, the bottom surface of the colorimetric tube contacts the bottom plate 22, and the upper part of the colorimetric tube is clamped by the clamping mechanism 25 on the upper plate hole 24, and then place the colorimetric tube rack 2 into the water tank of the water bath 1. For the colorimetric tube solution that needs to be protected from light, cover the water bath 1 cover 13, and then set the water bath temperature of the water bath 1, and perform water bath heating treatment on the colorimetric tube. After the treatment is completed, cool it with tap water through the water inlet pipe 11, and drain water through the water outlet pipe 12 at the same time, and slowly cool the colorimetric tube solution in the flowing tap water. The cooling speed can be adjusted by the first stop valve 111 and the second stop valve 121 to adjust the valve water inlet and outlet speeds, and control the water inlet speed to be greater than or equal to the water outlet speed to avoid overflow of the water bath 1. After cooling, take out the test tube rack through the handle plate 212.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
