Description
Technical Field
[0001] This utility model relates to the field of perchloric acid density meters, and particularly to a pressure-type online liquid density meter. Background Technology
[0002] Perchloric acid is an inorganic compound with the chemical formula HClO4, and is the hydrate of the highest-valence oxide of chlorine. Among inorganic oxyacids, perchloric acid is the strongest acid, ranking first among the six major strong inorganic acids. It is a colorless, transparent, fuming perchloric acid with strong corrosiveness, strong irritant properties, and flammability, and can cause burns to humans. A perchloric acid density meter uses a resonant cylinder density sensor to test the density of perchloric acid. After the perchloric acid to be measured is pumped into the resonant cylinder sensor, the measurement is processed by a microcontroller, which is fast, direct, and highly sensitive. This density meter can be widely used to measure the density of various perchloric acids, and with different concentration conversion software, it can also directly read the concentration or specific gravity of the corresponding perchloric acid. For example, with alcohol, the volume concentration data can be directly read through microcontroller software processing, making the test more convenient. A perchloric acid density meter is required for measurement during the production of perchloric acid.
[0003] In this regard, Chinese utility model patent CN204044020U discloses a pressure-type online liquid density meter. This pressure-type online liquid density meter includes a pressure level gauge, a measuring tube, a water inlet pipe, a liquid inlet pipe, a water inlet valve, a liquid inlet valve, an overflow pipe, an overflow device, and a recovery device. The pressure level gauge is installed below one end of the measuring tube. The measuring tube is connected to the water inlet pipe and the liquid inlet pipe. A water inlet valve is installed on the water inlet pipe, and a liquid inlet valve is installed on the liquid inlet pipe. An overflow device is installed at the top of the measuring tube and is connected to one end of the overflow pipe. A recovery device is installed at the other end of the overflow pipe.
[0004] However, pressure-type online liquid density meters do not have a pressure valve body, so different pressures cannot be set during measurement. They cannot perform density measurements under stable pressure environments, which cannot ensure the stability and repeatability of measurement results, thus reducing the quality and reliability of high-precision data.
[0005] Therefore, it is necessary to propose a pressure-type online liquid density meter to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a pressure-type online liquid density meter to solve the problems that, without a pressure valve, different pressures cannot be set during measurement, density measurement cannot be performed under a stable pressure environment, the stability and repeatability of measurement results cannot be guaranteed, and the quality and reliability of high-precision data are reduced.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a pressure-type online liquid density meter, including a density meter body, a tank is provided on the top surface of the density meter body, a second connecting pipe is fixed and connected to the bottom of the tank, the bottom end of the second connecting pipe is fixed and connected to the top of the density meter body, and a first valve body is provided on the second connecting pipe, the first valve body being a pressure valve;
[0008] The densitometer body has a third connecting pipe at its bottom and a third valve body at its top, which is a solenoid valve.

[0013] Preferably, the top surface of the densitometer body is fixedly connected to multiple fixing rods, and the top ends of the fixing rods are fixedly connected to the bottom surface of the tank.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. The present invention is equipped with a first valve body. By setting the first valve body, different pressures can be preset, and density measurement can be carried out under a stable pressure environment, which can ensure the stability and repeatability of the measurement results and improve the quality and reliability of the data.
[0016] 2. The first valve body can also effectively stabilize the working pressure of the equipment and prevent damage to the sensors and measuring elements inside the densitometer body due to excessively high or low pressure. The automatic adjustment function of the first valve body can automatically adjust the opening or closing state according to the actual pressure in the pipeline, ensuring the stability and reliability of the system and reducing problems caused by improper human operation or system failure.
[0017] 3. When the perchloric acid in the vessel is lower than the height of the third connecting pipe, the components can be matched to measure the perchloric acid in the vessel at intervals.

When the perchloric acid in the reactor is higher than the height of the third connecting pipe, the device can be used to continuously measure the perchloric acid in the reactor intermittently. This allows the staff to make real-time adjustments to the production process based on the density data to ensure that the product density is within the expected range. Real-time measurement of perchloric acid can also promptly detect and eliminate defective products, ensuring product quality. Attached Figure Description

[0024] 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.
[0025] This invention addresses the problem that the absence of a pressure valve body prevents the setting of different pressures during measurement, hindering density measurement under stable pressure conditions and compromising the stability and repeatability of measurement results. This ultimately reduces the quality and reliability of high-density data. The invention provides a solution such as… Figures 1-3The pressure-type online liquid density meter shown includes a density meter body 1, a tank 2 mounted on the top surface of the density meter body 1, a second connecting pipe 22 fixed to and connected to the bottom of the tank 2, and the bottom end of the second connecting pipe 22 fixed to and connected to the top of the density meter body 1. A first valve body 21, which is a pressure valve, is mounted on the second connecting pipe 22. The device is installed on the outer surface of the tank body to measure the perchloric acid inside the tank. The density meter body 1 has a mounting bracket for mounting the tank body, which is a mature existing technology and is not shown in the figure. When the tank body is stirred and measured, its interior is in a vacuum state. During detection, the perchloric acid inside the tank body enters the tank 2. When the perchloric acid in the tank 2 reaches a certain pressure value, the first valve body 21 opens, and the perchloric acid in the tank 2 enters the density meter body. Inside the device, the densitometer body 1 measures the density of perchloric acid. The densitometer body 1 can measure the perchloric acid in the vessel in real time, and the measured data is accurately fed back to the operator. Through the setting of the first valve body 21, different pressures can be preset, and density measurement can be carried out under a stable pressure environment, which can ensure the stability and repeatability of the measurement results, improve the quality and reliability of the data. The setting of the first valve body 21 can also effectively stabilize the working pressure of the equipment and prevent damage to the sensors and measuring elements inside the densitometer body 1 due to excessively high or low pressure. The automatic adjustment function of the first valve body 21 can automatically adjust the opening or closing state according to the actual pressure in the pipeline, ensuring the stability and reliability of the system and reducing problems caused by improper human operation or system failure.
[0026] In this utility model, a third connecting pipe 23 is fixed and connected to the outer periphery of the tank body 2. A second valve body 24 is provided on the third connecting pipe 23. The second valve body 24 is a one-way valve. During the installation process, the third connecting pipe 23 is installed on the top of the vessel body, and the flow direction of the second valve body 24 is one-way valve from the vessel body to the tank body 2.
[0027] It should be noted that when the highest liquid level of perchloric acid in the vessel is lower than the height of the third connecting pipe 23, the vessel stirs the perchloric acid inside. The perchloric acid is agitated by the stirring. When the agitation amplitude is higher than that of the third connecting pipe 23, the perchloric acid flows into the third connecting pipe 23. When the amplitude is lower, the perchloric acid remains in the vessel. The perchloric acid repeatedly and intermittently enters the third connecting pipe 23 and then enters the tank 2 from the third connecting pipe 23. When the perchloric acid in the tank 2 reaches the set pressure value, the first valve 21 opens, and the perchloric acid in the tank 2 flows into the densitometer body 1 for subsequent measurement. When the perchloric acid level is lower than that of the third connecting pipe 23, the perchloric acid in the vessel can be measured intermittently. Intermittent measurement within a predetermined time period can reduce the energy consumption of the densitometer body 1, extend its service life, and help reduce the burden on the data processing system, thereby processing and analyzing data more efficiently.
[0028] It should also be noted that when the highest liquid level of perchloric acid in the reactor is higher than the height of the third connecting pipe 23, the perchloric acid, during stirring, will continuously flow from the third connecting pipe 23 to the tank 2 due to the shaking. After the pressure in the tank 2 reaches the set value, subsequent measurements are performed through the cooperation of components. The perchloric acid continuously flows from the third connecting pipe 23 to the tank 2, and is then transported from the tank 2 to the densitometer body 1, thereby realizing the intermittent and continuous measurement of perchloric acid in the reactor. This allows the staff to make real-time adjustments to the production process based on the density data to ensure that the density of the product is within the expected range. Real-time measurement of perchloric acid can also promptly detect and eliminate defective products, ensuring product quality.
[0029] Furthermore, a third connecting pipe 3 is provided at the bottom of the densitometer body 1, and a third valve body 31 is provided at the top of the third connecting pipe 3. The third valve body 31 is a solenoid valve. After the densitometer body 1 has completed the measurement of perchloric acid, if the measurement result does not meet the standard, the third valve body 31 is opened, and the perchloric acid flows down from the densitometer body 1 into the third connecting pipe 3. Since the inside of the vessel is a vacuum, the perchloric acid that enters the third connecting pipe 3 will be sucked into the vessel. The stirring structure inside the vessel continues to stir the perchloric acid until it reaches the working density.
[0030] In this utility model, the bottom of the densitometer body 1 is fixed and connected to a first connecting pipe 11, and a feed pump 12 is installed on the first connecting pipe 11. After the measurement result is qualified, the third valve body 31 is in a closed state, the feed pump 12 is opened, and the feed pump 12 transports the qualified perchloric acid back into the reactor body, which facilitates subsequent work.
[0031] It should be noted that the top of the first connecting pipe 11 is fixed and connected to the bottom of the third connecting pipe 3, and the bottom of the third connecting pipe 3 is located above the feed pump 12. When the perchloric acid is qualified, the feed pump 12 will transport the qualified perchloric acid back to the reactor for unified processing. When it is unqualified, it will be transported to the top of the reactor by the third connecting pipe 3 for continued stirring.
[0032] In this invention, a control panel 13 is provided on the side wall of the densitometer body 1; the control panel 13 helps to set the parameters of the device, so that the device can work according to the set values.
[0033] In this invention, a plurality of fixing rods 25 are fixedly connected to the top surface of the densitometer body 1, and the top end of the fixing rods 25 is fixedly connected to the bottom surface of the tank 2; the fixing rods 25 help to fix the tank 2, making it more stable.
