Technical Field

[0001] The utility model belongs to the technical field of water quality analysis, and specifically relates to a silicon dioxide photometer. Background Art

[0002] Silicon dioxide (SiO2), as an important inorganic compound, is widely present in nature and has indispensable applications in industrial production. In many fields such as semiconductor manufacturing, glass processing and water treatment industries, the accurate determination of the silicon dioxide content in water is crucial. Traditional silicon dioxide detection methods mostly rely on chemical analysis methods, such as gravimetric methods and colorimetric methods. Although these methods can provide relatively accurate data, they are cumbersome and time-consuming to operate, and cannot meet the needs of modern water quality monitoring for rapid and accurate measurement. With the development of optoelectronic technology, photometers, as an efficient and convenient detection tool, have been widely used in water quality analysis.

[0003] However, current silica photometers still need further optimization in terms of structural design and ease of use. For example, some silica photometers on the market lack adequate protective measures, making it difficult to effectively resist external environmental interference with the detection module. This is especially true when used outdoors or in industrial sites, where the equipment is susceptible to environmental factors such as dust and moisture. Furthermore, the protective casing is not easy to remove, making maintenance of the internal detection module complicated.

[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places in this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Furthermore, this utility is described in detail with reference to schematic diagrams. For ease of explanation, the cross-sectional views of the device structures will be partially enlarged and not to scale when describing the embodiments of this utility. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of this utility. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0035] Please see the attached Figures 1-6 As shown, the present invention provides a silica photometer, comprising a mounting base 1, a U-shaped card slot 11 is provided on the outer surface of the mounting base 1, and a rubber sealing gasket is provided in the U-shaped card slot 11;

[0036] Detection module 2, which is embedded in the mounting base 1 and is used to detect the concentration of silica in water;

[0037] The detection box 3 is inserted into the mounting base 1 and is used to store samples to be tested;

[0038] The protective shell 4 is provided on the mounting base 1 and is located outside the detection module 2 to protect the detection module 2;

[0039] The fixing component 5 is arranged on the mounting base 1 and is used to fix the protective shell 4.

[0040] In this embodiment, the mounting base 1 has a U-shaped slot 11 for mounting the protective shell 4, and is equipped with a rubber sealing gasket, which not only ensures the sealing, but also has a damping effect to prevent the protective shell 4 from shaking. The detection box 3 is used to load the sample to be tested. The detection box 3 is connected to the mounting base 1 by plugging, making replacement and cleaning simple and convenient. The protective shell 4 protects the detection module 2 from the external environment. A heat sink (not shown in the figure) can be designed on the protective shell 4 to help the detection module 2 maintain an appropriate temperature when working for a long time. The fixing component 5 ensures that the protective shell 4 is firmly fixed on the mounting base 1.

[0041] It should be noted that the detection module 2 includes a light source (810nm red light), a photodiode, a temperature sensor, a heating resistor, a temperature fuse, and a filter. The light source emits light of a specific wavelength, which is absorbed by the sample and then received by the photodiode and converted into an electrical signal, which is processed to obtain the detection result.

[0042] During the actual detection process, the operator places the sample to be tested into the detection box 3, and then gradually adds the reactants. After that, the light source emits 810nm red light to pass through the sample, and the photodiode detects the light intensity after passing through the sample and converts it into an electrical signal. The temperature sensor monitors the sample temperature to ensure the consistency of the test conditions. If the temperature needs to be adjusted, the heating resistor plays a role and heats the sample to reach the optimal detection temperature. The entire detection process is highly automated, simple and quick to operate, and is suitable for silica concentration detection in various occasions. The temperature fuse serves as a safety device to prevent the detection module 2 from being damaged by overheating. The filter is used to filter out light of non-target wavelengths to ensure the accuracy of the detection.

[0043] Detection method based on silica concentration: add an acidic molybdate solution containing trivalent molybdate to the sample to be tested, so that it reacts with the silica and phosphate present in the sample to generate silicomolybdic acid and phosphomolybdic acid.

[0044] Citric acid and a surfactant are then added. The citric acid can screen out the phosphomolybdic acid present in the sample and react with excess molybdate, while the surfactant helps reduce bubble formation and ensure measurement accuracy.

[0045] By measuring the absorbance of the solution and comparing it with the absorbance of a blank sample, the effects of sample background turbidity, variations in cuvette bulb output, or contamination of the sample flow cell walls can be eliminated.

[0046] Finally, Amino Acid F reagent is used to reduce silicomolybdic acid to a blue solution. The intensity of the resulting blue color is proportional to the silica concentration in the sample. The silica concentration can be determined by measuring the solution's absorbance at 810 nm and comparing it with that of a blank sample. It should be emphasized that since the core technology of this method is not protected by utility model patents, this article will only briefly describe its basic principles and will not elaborate in detail.

[0047] In a preferred embodiment, see Figure 2 A plug plate 41 is fixedly connected to the protective shell 4 , a lock hole 42 is opened on the plug plate 41 , and a sealing ring is also provided at one end of the protective shell 4 located at the plug plate 41 .

[0048] Next, please refer to Figure 3-Figure 6 The fixing component 5 includes a movable groove 501, which is opened on the mounting base 1. The side of the mounting base 1 is rotatably connected to a rotating rod 502, one end of the rotating rod 502 is fixedly connected to a knob 503, the outer wall of the rotating rod 502 is sleeved with a wire block 504, the outer wall of the wire block 504 is fixedly sleeved with a movable plate 505, and a locking block 506 is fixedly connected to the movable plate 505. A limiting groove 507 is opened on the inner wall of the movable groove 501, and a limiting block 508 is slidably connected in the limiting groove 507, and the limiting block 508 is fixedly connected to the movable plate 505, wherein the outer wall of the rotating rod 502 is opened with a thread compatible with the wire block 504, and the rotating rod 502 is threadedly connected to the wire block 504.

[0049] In this embodiment, the protective shell 4 is first inserted into the U-shaped slot 11 provided on the outer surface of the mounting base 1, and the inserting plate 41 is inserted into the movable slot 501. Then, the knob 503 is twisted. When the knob 503 is rotated clockwise, the rotating rod 502 rotates accordingly, causing the wire block 504 to move. The movement of the wire block 504 drives the movable plate 505 to move toward the other end of the limiting slot 507. The movement of the movable plate 505 drives the locking block 506 to move until the locking block 506 is inserted into the lock hole 42. At this point, the locking block 506 is tightly fitted with the lock hole 42 to lock the protective shell 4. When unlocking is required, the knob 503 is rotated counterclockwise, the rotating rod 502 drives the wire block 504 to move in the opposite direction, and the movable plate 505 moves to the initial position. The locking block 506 disengages from the lock hole 42, thereby achieving unlocking.

[0050] In addition, when the movable plate 505 moves, the limiting block 508 thereon slides along the limiting groove 507, which can play a guiding and limiting role, thereby ensuring the stability of the movement of the movable plate 505 and ensuring that the locking block 506 can be accurately inserted into the locking hole 42.

[0051] By operating the knob 503 , the protective shell 4 can be conveniently locked and unlocked, ensuring the safety of the device and the convenience of operation.

[0052] It should be noted that the surface of knob 503 is provided with anti-slip grooves, which allows for a more secure grip during operation and prevents misoperation due to hand slippage. In addition, the hexagonal groove design on the side not only enhances the aesthetics of knob 503, but also provides additional twist points, further improving the convenience and accuracy of operation.

[0053] In practical applications, the anti-slip grooves and hexagonal grooves of the knob 503 make it easier to apply rotational torque when locking or unlocking. This design ensures that the knob 503 will not slip when subjected to large torque, thereby ensuring the safety of the device, especially in situations where the protective shell 4 needs to be firmly locked.

[0054] Furthermore, the Knob 503's structural design takes long-term durability into consideration. The anti-slip grooves and hexagonal grooves on the surface effectively prevent wear and tear, extending the lifespan of the Knob 503. Even under frequent operation, the Knob 503 maintains its pleasant feel and appearance, ensuring the overall reliability and stability of the photometer.

[0055] In a preferred embodiment, see Figure 4 The limit block 508 is provided with a ball bearing. The ball bearing fits tightly with the inner wall of the limit groove 507. The provision of the ball bearing greatly reduces the friction of the movable plate 505 during the sliding process, thereby improving the overall service life and reliability, and ensuring the smoothness and positioning accuracy of the limit block 508 when sliding in the limit groove 507.

[0056] Next, please refer to Figure 6 , the locking block 506 has a trapezoidal structure; as the locking block 506 gradually penetrates into the locking hole 42, the trapezoidal locking block 506 gradually embeds into the locking hole 42, thereby exerting a resistance force on the plugboard 41, causing the plugboard 41 to further penetrate into the movable groove 501, thereby promoting the end face of the protective shell 4 to be in close contact with the mounting seat 1, and at the same time exerting pressure on the sealing ring on the end face of the protective shell 4 to enhance the sealing effect.

[0057] The working principle of this utility is:

[0058] First, the operator places the sample to be tested into the test cartridge 3 and, following the prescribed procedure, adds the necessary chemical reagents, such as acidic molybdate solution, citric acid, and surfactants. These reagents react with the silica in the sample to produce a substance of a specific color, facilitating subsequent optical detection.

[0059] The light source (810nm red light) then emits a specific wavelength of light that passes through the sample solution. Due to the chemical reaction in the solution, the light intensity changes. This change is captured by the photodiode and converted into a corresponding electrical signal.

[0060] The protective shell 4 covers the outside of the detection module 2 and is connected to the mounting base 1 through the fixing component 5 to ensure that the detection module 2 is not interfered with by external environmental factors. The design of the fixing component 5 makes the installation and removal of the protective shell 4 simple and quick, and facilitates maintenance.

[0061] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
