Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a portable spectrophotometric testing device for the hardness of industrial boiler water. Background Technology

[0002] Industrial boilers are devices used to heat water and convert it into steam or hot water. They are widely used in various industrial fields. The hardness detection of industrial boiler water is crucial to ensuring the safe operation of the boiler and extending its service life. To make the detection more convenient and faster, a portable spectrophotometric detection device has been designed. The spectrophotometer measures the absorbance of the solution at a specific wavelength. Water samples with different hardness will produce different absorbance values. The hardness value can be calculated through the calibration curve.

[0003] There are still some problems in the use of existing portable spectrophotometric detection devices for industrial boiler water hardness. Traditional portable detection devices usually rely on simple stirring mechanisms or manual shaking when mixing reagents and water. This method may lead to uneven mixing and affect the accuracy of the detection results. Therefore, those skilled in the art have provided a portable spectrophotometric detection device for industrial boiler water hardness to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable spectrophotometric detection device for industrial boiler water hardness. By setting up a sample storage structure, the device ensures thorough mixing of reagents and boiler water. The mixing is achieved not only through the rotation of the stirring rod but also through vibration, thereby improving the mixing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable spectrophotometric detection device for industrial boiler water hardness, comprising a device housing, a control panel, and a battery module. The control panel is located at the front center of the upper end face of the device housing, and the battery module is located at the front inside the device housing. A storage tank is provided at the rear center of the lower end face of the device housing, and a bottom plate is provided at the lower part of the storage tank. A second universal support and a first universal support are arranged horizontally on the inner wall of the storage tank, and a sample storage structure is provided inside the first universal support.

[0006] The sample storage structure includes a high-strength glass cup with a top cover on the upper surface. A micro servo motor is fixedly connected to the center of the upper surface of the top cover. The output end of the micro servo motor passes through the upper surface of the top cover and extends into the interior of the high-strength glass cup. A stirring rod is fixedly connected to the end of the motor. A striking block is fixedly connected to the upper part of the outer wall of the stirring rod. A protrusion is fixedly connected to the lower surface of the top cover on the side of the striking block.

[0007] A groove is provided on the upper end face of the upper device housing of the first universal support and the second universal support. A through hole is provided on the upper inner wall of the upper storage groove of the first universal support. The through hole leads to the lower inner wall of the groove. A spectrophotometer is provided inside the second universal support.

[0008] The above technical solution involves placing the reagent and boiler water inside a high-strength glass cup, covering the cup with a top cover, inserting a stirring rod into the cup, and starting a micro servo motor. The motor drives the stirring rod to stir the reagent and boiler water. As the stirring rod rotates, a striking block strikes a protrusion, generating vibrations. This simultaneous stirring and vibration enhances the mixing effect and improves mixing efficiency.

[0009] Furthermore, the first universal support includes two support rods, which are respectively disposed on the upper inner wall of the storage slot at two opposite corners at the lower end of the through hole. A first bracket is rotatably connected between the two support rods. A first counterweight is fixedly connected to the lower end face of the first bracket. A second bracket is rotatably connected inside the first bracket. A second counterweight is fixedly connected to the lower end face of the second bracket. A placement cavity is fixedly connected at the center of the upper end face of the second bracket.

[0010] The above technical solution uses a first counterweight frame to counterweight the first support and a second counterweight frame to counterweight the second support, causing the first and second supports to rotate with the connection position, thus ensuring that the spectrophotometer detector and the high-strength glass cup are always in a horizontal state.

[0011] Furthermore, the rotation axis of the support rod and the rotation axis of the second bracket are arranged in a cross shape;

[0012] The above technical solution facilitates adaptation to different tilt angles.

[0013] Furthermore, a protective cover is rotatably connected to the upper part of the groove, and an extension groove is provided on the upper inner wall of the protective cover located at the upper end of the sample storage structure.

[0014] The above technical solution facilitates the protection of protruding parts of the sample storage structure.

[0015] Furthermore, the spectrophotometric detector includes a light source, a spectrophotometric system, and a detector;

[0016] Using the above technical solution, the absorbance of the solution at a specific wavelength is measured using a spectrophotometer. Water samples with different hardness will produce different absorbance values, and the hardness value can be calculated through the calibration curve.

[0017] Furthermore, the structure of the second universal support is consistent with the structure of the first universal support;

[0018] The above technical solution ensures that the spectrophotometer can vertically illuminate the water inside the high-strength glass.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the portable spectrophotometric detection device for industrial boiler water hardness first places the reagent and boiler water inside a high-strength glass cup, then covers the high-strength glass cup with the top cover, inserts the stirring rod into the high-strength glass cup, and controls the micro servo motor to start. The micro servo motor drives the stirring rod to stir the reagent and boiler water. During the rotation of the stirring rod, the striking block strikes the protrusion to generate vibration, thus enhancing the mixing effect and improving the mixing efficiency.

[0021] 2. In this utility model, the first counterweight frame counterweights the first support, and the second counterweight frame counterweights the second support, so that the first and second supports rotate with the connection position, thereby ensuring that the spectrophotometer detector and the high-strength glass cup are always in a horizontal state. This prevents the light from becoming longer in the liquid when the light source, monitor, and spectrophotometer system are tilted to illuminate the sample cell. Since absorbance is proportional to the optical path length, an increase in the optical path length will cause a change in the absorbance measurement value, thus affecting the accuracy of the detection results.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 An embodiment of this utility model provides a portable spectrophotometric detection device for industrial boiler water hardness, comprising a device housing 1, a control panel 2, and a battery module 8. The control panel 2 is located at the front center of the upper end face of the device housing 1, and the battery module 8 is located at the front inside the device housing 1. A storage tank 6 is provided at the rear center of the lower end face of the device housing 1. A bottom plate 7 is provided at the lower part of the storage tank 6. A second universal support 12 and a first universal support 10 are arranged horizontally on the inner wall of the upper part of the storage tank 6. A sample storage structure 9 is provided inside the first universal support 10.

[0031] The sample storage structure 9 includes a high-strength glass cup 901. A top cover 902 is provided on the upper surface of the high-strength glass cup 901. A micro servo motor 903 is fixedly connected to the center of the upper surface of the top cover 902. The output end of the micro servo motor 903 passes through the upper surface of the top cover 902 and extends into the interior of the high-strength glass cup 901. A stirring rod 904 is fixedly connected to the end of the stirring rod 904. A striking block 905 is fixedly connected to the upper part of the outer wall of the stirring rod 904. A protrusion 9 is fixedly connected to the lower surface of the top cover 902 on one side of the striking block 905. 06. First, place the reagent and boiler water inside the high-strength glass cup 901, and cover the high-strength glass cup 901 with the top cover 902. Insert the stirring rod 904 into the high-strength glass cup 901 and start the micro servo motor 903. The micro servo motor 903 drives the stirring rod 904 to stir the reagent and boiler water. During the rotation of the stirring rod 904, the striking block 905 strikes the protrusion 906 to generate vibration, which enhances the mixing effect and improves the mixing efficiency by stirring and vibrating at the same time.

[0032] A groove 3 is provided on the upper end face of the upper device housing 1 of the first universal support 10 and the second universal support 12. A through hole 11 is provided on the upper inner wall of the upper storage tank 6 of the first universal support 10, and the through hole 11 leads to the lower inner wall of the groove 3. A spectrophotometer 13 is provided inside the second universal support 12. The spectrophotometer 13 and the high-strength glass cup 901 are always in a horizontal state to prevent the light from becoming longer in the liquid when the light source, monitor and spectrophotometer system are tilted to irradiate the sample cell. The absorbance is proportional to the optical path length. The increase of the optical path will cause the absorbance measurement value to change, thereby affecting the accuracy of the detection result.

[0033] like Figure 2 , 4 As shown in Figure 5, the first universal support 10 includes two support rods 1001, which are respectively disposed on the upper inner walls of the storage slots 6 at two opposite corners at the lower end of the through hole 11. A first bracket 1002 is rotatably connected between the two support rods 1001. A first counterweight frame 1003 is fixedly connected to the lower end face of the first bracket 1002. A second bracket 1004 is rotatably connected inside the first bracket 1002. A second counterweight frame 1006 is fixedly connected to the lower end face of the second bracket 1004. A placement cavity 1005 is fixedly connected to the center of the upper end face of the second bracket 1004. The first counterweight frame 1003 provides counterweight to the first bracket 1002, and the second counterweight frame 1006 provides counterweight to the second bracket 1004, so that the first bracket 1002 and the second bracket 1004 rotate with the connection position, thereby ensuring that the spectrophotometer 13 and the high-strength glass cup 901 are always in a horizontal state.

[0034] The rotation axis of the support rod 1001 and the rotation axis of the second bracket 1004 are arranged in a cross shape to facilitate adaptation to different angles of tilt.

[0035] like Figure 1 , 2 As shown in Figure 4, a protective cover 4 is rotatably connected to the upper part of the groove 3. An extension groove 5 is provided on the upper inner wall of the protective cover 4 located at the upper end of the sample storage structure 9 to facilitate the protection of the protruding parts of the sample storage structure 9.

[0036] The spectrophotometer 13 includes a light source, a spectrophotometer system, and a detector. The spectrophotometer 13 is used to measure the absorbance of a solution at a specific wavelength. Water samples with different hardness will produce different absorbance values. The hardness value can be calculated through the calibration curve.

[0037] The structure of the second universal support 12 is the same as that of the first universal support 10, which makes it easy to ensure that the spectrophotometer 13 can vertically irradiate the water inside the high-strength glass cup 901.

[0038] Working principle: When in use, first place the reagent and boiler water inside the high-strength glass cup 901, then cover the high-strength glass cup 901 with the top cover 902, insert the stirring rod 904 into the high-strength glass cup 901, and start the micro servo motor 903. The micro servo motor 903 drives the stirring rod 904 to stir the reagent and boiler water. During the rotation of the stirring rod 904, the striking block 905 strikes the protrusion 906 to generate vibration, which enhances the mixing effect and improves the mixing efficiency by stirring and vibrating simultaneously.

[0039] After mixing, remove the top cover 902 and place the high-strength glass cup 901 inside the placement cavity 1005. The first counterweight frame 1003 counterweights the first support 1002, and the second counterweight frame 1006 counterweights the second support 1004, causing the first support 1002 and the second support 1004 to rotate with the connection position. This ensures that the spectrophotometer detector 13 and the high-strength glass cup 901 are always in a horizontal state. This prevents the light from becoming longer in the liquid when the light source, monitor, and spectrophotometer system are tilted to illuminate the sample cell. Since absorbance is proportional to the optical path length, an increase in the optical path length will cause changes in the absorbance measurement value, thus affecting the accuracy of the detection results.

[0040] After the test is completed, the high-strength glass cup 901 is taken out, the water after the test is treated, and then washed and dried together with the stirring rod 904 before being placed inside the placement cavity 1005 and covered with the protective cover 4 for transport.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
