Description

Technical Field

[0001] This utility model relates to the field of chemical testing technology, specifically a device for rapidly determining the type I content in sodium tripolyphosphate. Background Technology

[0002] Sodium tripolyphosphate (STP), an important inorganic chemical raw material, is widely used in various industrial fields such as detergents, food processing, and water treatment. The type I content of STP determines its core industrial performance, directly affecting the production efficiency and application effects of downstream products. For example, in detergent production, excessively high or low type I content can lead to abnormal dissolution rates, thus affecting the formulation stability and user experience of the detergent. In food processing, precise control of type I content is crucial for the uniform dispersion of food additives and product quality and safety. Therefore, rapid and accurate detection of type I content in STP is a vital step in ensuring the continuity of industrial production and product quality. However, the traditional methods used in the industry for detecting sodium tripolyphosphate type I content have significant efficiency bottlenecks and equipment deficiencies, making them unsuitable for the high demands of modern industrial production for timely detection and data reliability. In terms of efficiency, traditional methods are complex and time-consuming, with a single detection process taking over 20 minutes. This level of efficiency severely limits the number of samples that can be processed when dealing with the batch sample testing needs of industrial production lines. It also leads to delayed feedback of test results, failing to provide timely guidance for adjusting production parameters and potentially resulting in the risk of mass production of substandard products. Regarding testing equipment, traditional testing systems suffer from multiple technical deficiencies in their instruments and equipment, further exacerbating the instability and data deviation problems in the testing process. Specifically, the right-angle thermometers used for temperature monitoring in traditional methods are made of fragile glass with poor impact resistance, making them highly susceptible to damage during frequent operation and movement in industrial workshops, leading to testing interruptions. Meanwhile, electronic thermostatic stirrers used for mixing generally suffer from low operational sensitivity and are significantly affected by fluctuations in grid voltage. When voltage fluctuates, the stirrer's speed regulation becomes unstable, often exhibiting sudden increases or decreases in speed or even stopping. This not only disrupts the temperature uniformity and reaction consistency of the testing system but also leads to significant deviations in the test data, failing to accurately reflect the true type I content of sodium tripolyphosphate. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for rapidly determining the content of type I sodium tripolyphosphate, which can solve the problem of low efficiency of traditional methods for detecting the content of type I sodium tripolyphosphate, and achieve the purpose of shortening the detection time, improving the stability of the detection equipment and the ease of operation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for rapidly determining the content of type I sodium tripolyphosphate, including a box, wherein a beaker positioning protrusion is provided on the bottom surface of the box, and the beaker positioning protrusion is used to fix the position of the beaker in the box; A digital display probe thermometer and a lifting rod are movably installed on the top of the box.

[0005] In a preferred embodiment, one side of the housing is an opening, and a door panel is provided on the opening side, with an observation window on the door panel; The inner side of the door panel is also provided with an annular protrusion, which forms an interference fit with the inner cavity of the box when the door panel is closed.

[0006] In a preferred embodiment, a buffer rod with a length greater than that of the vertical part of the stirring rod is also provided on the bottom surface of the horizontal part of the stirring rod, and the buffer rod extends vertically downward to a position close to the bottom surface of the box.

[0007] In a preferred embodiment, a cylinder is provided on the bottom surface of the near-box body, a buffer spring is provided at the bottom of the cylinder, and the lower end of the buffer rod is inserted into the cylinder.

[0008] In a preferred embodiment, the upper end of the lifting rod extends above the top surface of the housing, the upper part of the lifting rod is provided with a rack, a motor is provided on the top surface of the housing, and a gear is provided on the motor, the gear meshing with the rack.

[0009] In a preferred embodiment, the gear is an incomplete gear, and the number of teeth on the gear is the same as the number of teeth on the rack.

[0011] In a preferred embodiment, a control module is provided on one side of the housing, and a timing module is configured within the control module; The control module is connected to a digital display probe thermometer, a motor, and an electrically controlled valve.

[0012] The device provided by this invention for rapidly determining the type I content in sodium tripolyphosphate has the following advantages by adopting the above structure: (1) The stirring system relies on the meshing transmission of motor, gear and rack to achieve lifting and lowering. With the incomplete gear design, it can drive the stirrer to make longitudinal reciprocating motion, accurately control the movement trajectory and range of the stirring rod, and avoid the problem of unstable operation caused by external factors in traditional stirrers. (2) The control module realizes centralized control of thermometer, motor and electric valve. Operators do not need to frequently switch between different devices. They can complete core operations such as detection and start-up and parameter adjustment through the control module alone. (3) The entire testing process is located in a relatively enclosed box space, which can isolate the equipment from damage caused by human error or external influence. Attached Figure Description

[0023] The present invention discloses an apparatus for rapidly determining the type I content in sodium tripolyphosphate. When performing the determination of type I content in sodium tripolyphosphate: First, open the door panel 2, weigh 50g of glycerin into beaker 5 and add 50g of sample. Then, manually lift the digital display probe thermometer 7 and the lifting rod 10 (before lifting the lifting rod 10, ensure that the notch of gear 13 is aligned with the rack 11), place beaker 5 inside the box 1, and position it using the beaker positioning protrusion 6.
