Description

TECHNICAL FIELD

[0001] The utility model relates to the field of laboratory liquid quantity taking, more particularly to a viscous liquid quantitative detection device and system. BACKGROUND

[0002] In the field of chemistry and materials science, for high-viscosity chemical liquids such as phosphoric acid liquids, accurate measurement of their physical properties is crucial for process control and product quality assurance. One key physical property of such liquids is viscosity, which describes the degree of stickiness and is an important indicator of fluidity. However, there are many problems in measuring such liquids, especially at different temperatures, as their density changes, further increasing the complexity of measurement.

[0003] Currently, for weighing a certain amount of high-viscosity phosphoric acid chemical liquid, the method of hot water bath + hydrometer is usually used for manual measurement. The basic steps of this method are as follows: first, place the chemical liquid in a hot water bath to reach a stable measurement temperature, because temperature changes will affect the density and viscosity of the liquid. Then, use a hydrometer to measure the specific gravity of the liquid, i.e. the ratio of the density of the liquid to that of a certain reference material. After the specific gravity meets the requirements, the operator manually pours out a certain amount of solution for subsequent use or analysis. However, this method has obvious limitations. First of all, it requires a very high level of operator, as the measurement process requires precise temperature control, accurate reading of the hydrometer data, and pouring out of the solution at the right time, any operational error can lead to measurement deviation. Secondly, this method is greatly affected by human instability, even experienced operators cannot guarantee completely consistent results every time. Moreover, human judgment and operation are always disturbed by external factors such as fatigue and distraction. In addition, for high-viscosity liquids, their fluidity is poor in itself, which makes it more prone to errors in measurement and pouring. For example, the liquid may form a stagnant or adherent in the pipeline or container, resulting in a discrepancy between the actual measured liquid volume and the design requirements.

[0004] Therefore, in order to overcome the limitations of the prior art, it is necessary to develop a more accurate, stable and easy-to-operate measurement method to weigh a certain amount of high-viscosity phosphoric acid chemical liquid. This method should be able to accurately measure the specific gravity of the liquid at a specific temperature and automatically pour out a certain amount of solution after meeting the requirements. This not only improves the accuracy and efficiency of measurement, but also reduces the requirements and dependence on operators, thereby improving the stability and reliability of the entire production process.

[0063] The technical methods of this 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 this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0064] Example 1

[0065] like Figure 1 As shown, this embodiment provides a quantitative detection device for viscous liquids, comprising:

[0066] Measuring container 100 is connected in series on the viscous liquid production line to contain a fixed quantity of viscous liquid;

[0067] The stirring component 200 is connected to the measuring container 100 and stirs the liquid inside the measuring container 100;

[0068] Temperature control component 300 is installed on measuring container 100 to regulate the temperature inside measuring container 100;

[0069] The weighing component 400 is located on one side of the measuring container 100 and connected to the measuring container 100, and is used to measure the weight of the liquid inside the measuring container.

[0070] The inlet 500 is located on the top surface of the measuring container 100 and is connected to an external input pipeline. The viscous liquid on the production line is transported to the measuring container 100 through the external input pipeline.

[0071] The discharge port 600 is located at the bottom of the measuring container 100 and is connected to an external output pipeline. The liquid inside the measuring container 100 is discharged through the external output pipeline.

[0072] When measuring the liquid at a certain temperature, the liquid on the production line is transported into the measuring container 100 through the external input pipeline via the inlet 500, when the liquid in the measuring container 100 reaches a certain amount, no more liquid is fed, the appropriate temperature is set, the temperature control assembly 300 starts heating, and the stirring assembly 200 continuously stirs during the heating process to ensure the uniformity of the material and improve the heating effect. When the temperature of the liquid is consistent with the preset temperature and the liquid is in a uniform state, the stirring is stopped, and the data of the weighing assembly 400 is obtained. After the weighing is completed, the liquid in the measuring container 100 is discharged and output to the production line through the output pipeline via the outlet 600, and the liquid on the production line is measured. Integrating the measuring work into the entire production line improves the measuring efficiency, reduces the waste of liquid, and the measured liquid amount is large, and the measurement is more accurate.

Moreover, by surrounding the side wall of the measuring container 100 with the heating sheet, the heating area is increased, the heating rate is improved, and the heating effect is more uniform and stable. In addition, this method also has certain heat preservation effect.

The narrow part of the trapezoid is just away from the detection end of the temperature measuring device 310, avoiding the collision between the stirring assembly 200 and the temperature measuring device 310 during stirring, which can cause device damage. The stirring frame is composed of a sheet with a certain width, which can reduce the stirring resistance and has good stirring effect. The stirring paddle 210 is arranged in the stirring area and the height matches the stirring area, which can fully measure the liquid in the measuring container 100. Through the combination of the driving device 220 and the stirring paddle 210, the purpose of uniform stirring is achieved. The stirring rate of the driving device 220 can be adjusted to achieve the desired stirring effect. Moreover, it also promotes the container emptying process.
