Description

Technical Field

[0001] This utility model relates to the technical field of glass water collection and metering equipment, specifically a glass water collection and metering device with graduations. Background Technology

[0002] In many chemical reactions, determining the progress of a compound reaction based on the amount of water is crucial. This is because water is closely linked to chemical equilibrium. For example, in reactions such as esterification and hydrolysis, the amount of water can indicate whether the reaction has reached equilibrium and can be used to calculate the equilibrium constant. From the perspective of reaction rate, in reactions such as condensation and polymerization, the amount of water can reflect the reaction rate, which is beneficial for controlling the industrial production process. At the same time, the amount of water can also be used to monitor side reactions, such as hydrolysis side reactions in organic synthesis and oxidation side reactions when metals react with acids. This can help determine the type and extent of side reactions and improve the selectivity of the main reaction. Therefore, water metering devices with metering functions are indispensable auxiliary tools for some chemical experiments.

[0003] Existing graduated glass water collecting and measuring devices typically have measuring lines engraved on the surface of the device body. To enhance visibility, the grooves are often filled with pigment. However, in actual long-term use, due to frequent contact with various chemical reagents, friction from cleaning tools, and collisions during daily operation, the measuring lines are easily worn away. As the wear intensifies, the clarity of the measuring lines decreases significantly, becoming blurred. When taking readings, it is difficult for experimenters to accurately determine the corresponding position of the liquid level and the measuring line, resulting in significant observational deviations. Ultimately, this seriously affects the measurement accuracy and greatly reduces the reliability of experimental data. Furthermore, glass water collecting devices are easily affected by external temperature, causing the water to expand and contract, which can lead to measurement errors. Therefore, we propose a graduated glass water collecting and measuring device. Utility Model Content

[0004] The main purpose of this invention is to provide a graduated glass water collection and metering device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a graduated glass water collection and metering device, comprising a conduit, a third connector detachably connected to the center of the lower surface of the conduit, a liquid storage metering cylinder detachably connected to the bottom end of the third connector, the liquid storage metering cylinder comprising a glass outer shell, a glass inner tube, metering scale lines, and a vacuum chamber, the glass inner tube being fixedly connected to the inner cavity of the glass outer shell, the surface of the glass inner tube being vertically engraved with metering scale lines, and the surface of the metering scale lines being filled with fluorescent paint, and a vacuum chamber being provided between the glass outer shell and the glass inner tube.

[0006] Preferably, the third connector includes a connecting cylinder, a liquid guiding channel, a plug, and an elastic connecting rod. The connecting cylinder has a liquid guiding channel in its inner cavity, and the elastic connecting rod is detachably connected to the bottom end of the inner cavity of the connecting cylinder. The elastic connecting rod is detachably connected to a plug on one side of the liquid guiding channel.

[0007] Preferably, the plug has a conical head, and the liquid channel is located on one side of the plug and has an inverted conical shape that matches the plug.

[0008] Preferably, a liquid level sensor is detachably connected to one side of the inner cavity of the third connector, and the liquid level sensor is electrically connected to an externally configured PLC via a wire.

[0009] Preferably, a sealing sleeve is detachably connected to the bottom end of the liquid storage metering cylinder, and a solenoid valve is detachably connected to the inner cavity of the sealing sleeve. The solenoid valve is electrically connected to an externally configured PLC via a wire.

[0010] Preferably, a first connector is detachably connected to one side of the conduit, and an inlet tube is detachably nested at the center of the outer side wall of the first connector.

[0011] Preferably, the conduit is detachably connected to a second connector on one side relative to the first connector, and a discharge pipe is detachably nested at the center of the outer side wall of the second connector.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes the interplay of a glass outer shell, a glass inner tube, measuring scale lines, and a vacuum chamber. The glass outer shell effectively encloses the glass inner tube and the measuring scale lines engraved on its surface, preventing corrosion and wear during long-term use and ensuring accurate measurement. Furthermore, the vacuum chamber between the glass outer shell and the glass inner tube effectively isolates the liquid, preventing external temperatures from affecting the stored water and reducing the degree of thermal expansion and contraction of the liquid inside the cylinder due to changes in ambient temperature. This results in more stable and accurate readings on the measuring scale lines, significantly improving the measurement accuracy of the liquid storage measuring cylinder under different temperature conditions and providing reliable liquid measurement assurance for temperature-sensitive chemical reactions or experiments.

[0014] 2. This utility model utilizes a connecting cylinder, a liquid guiding channel, a plug, an elastic connecting rod, and a liquid level sensor working together. When the liquid in the storage measuring cylinder overflows, it pushes the plug upward, causing the plug to fit against the liquid guiding channel, thus sealing the channel and preventing liquid backflow. Furthermore, when the liquid reaches the position of the liquid level sensor, the sensor transmits a signal to an external control device. The control device automatically opens the solenoid valve in the sealing sleeve at the bottom of the storage measuring cylinder, allowing the liquid to drain outward and preventing overflow backflow, further ensuring the stability of the collection.

[0019] 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. Example

[0020] Please see Figure 1 - Figure 3The diagram illustrates a graduated glass water collection and metering device, comprising a conduit 1. A third connector 5 is detachably connected to the center of the lower surface of the conduit 1. A liquid storage metering cylinder 6 is detachably connected to the bottom end of the third connector 5. The liquid storage metering cylinder 6 includes a glass outer shell 601, a glass inner tube 602, metering graduation lines 603, and a vacuum chamber 604. The glass inner tube 602 is fixedly connected to the inner cavity of the glass outer shell 601. The metering graduation lines 603 are vertically engraved on the surface of the glass inner tube 602 and filled with fluorescent paint. A vacuum chamber 604 is provided between the glass outer shell 601 and the glass inner tube 602. During water collection, the glass outer shell 601 protects the inner tube and graduation lines, and the vacuum chamber 604 effectively insulates against heat, ensuring accurate display of the metering graduation lines 603. Simultaneously, the graduation lines filled with fluorescent paint facilitate data reading under different lighting conditions, providing a stable, reliable, and convenient operating experience for liquid metering.

[0021] The third connector 5 includes a connecting cylinder 501, a liquid guiding channel 502, a plug 503, and an elastic connecting rod 504. The connecting cylinder 501 has a liquid guiding channel 502 inside its cavity. The elastic connecting rod 504 is detachably connected to the bottom end of the inner cavity of the connecting cylinder 501. The plug 503 is detachably connected to one side of the elastic connecting rod 504, which is located on the liquid guiding channel 502. The plug 503 has a conical head, and the liquid guiding channel 502 is located within the plug 503. One side of the plug 503 is inverted conical in shape to match the plug 503. During normal operation, the liquid can push the plug 503 open by its own weight or pressure and smoothly enter the liquid storage metering cylinder 6 through the liquid guiding channel 502. When the liquid level in the liquid storage metering cylinder 6 rises abnormally or when it is necessary to stop the liquid supply, the plug 503 can quickly and tightly fit the inverted conical port of the liquid guiding channel 502 under the action of the elastic connecting rod 504, reliably sealing the channel, preventing liquid backflow, and ensuring the stability and safety of the entire liquid delivery system.

[0022] The third connector 5 has a liquid level sensor 10 detachably connected to one side of its inner cavity. The liquid level sensor 10 is electrically connected to an externally configured PLC via a wire. The bottom of the liquid storage metering cylinder 6 is detachably connected to a sealing sleeve 7. The inner cavity of the sealing sleeve 7 is detachably connected to a solenoid valve 8, which is also electrically connected to an externally configured PLC via a wire. When the liquid level sensor 10 detects that the liquid level has reached the set value, it can quickly transmit a signal to the PLC. The PLC then controls the solenoid valve 8 to operate, accurately controlling the discharge of liquid. This eliminates the need for real-time manual monitoring, effectively improving the automation level of the liquid metering and discharge process, reducing human error, and increasing work efficiency.

[0023] The conduit 1 is detachably connected to a first connector 2 on one side. An inlet pipe 3 is detachably nested at the center of the outer wall of the first connector 2. A second connector 4 is detachably connected to the side of the conduit 1 opposite to the first connector 2. An outlet pipe 9 is detachably nested at the center of the outer wall of the second connector 4. By setting detachably connected first connectors 2 and second connectors 4 on both sides of the conduit 1, and by detachably nesting the first connector 2 with the inlet pipe 3 and the second connector 4 with the outlet pipe 9, flexible switching and expansion of liquid input and output paths are realized. This facilitates adaptation to different liquid supply and collection devices and greatly improves the versatility and practicality of the entire metering equipment in various experimental and production scenarios.

[0024] It should be noted that this utility model is a graduated glass water collecting and measuring device. During collection, the liquid flows into the liquid guiding channel 502 of the third connector 5 through the conduit 1. Under the action of the elastic connecting rod 504, the plug 503 moves away from the inverted conical port of the liquid guiding channel 502, and the liquid flows smoothly into the glass inner tube 602 for storage. During the liquid flow process, the glass outer shell 601 effectively isolates external corrosive substances, protects the measuring scale lines 603 on the surface of the glass inner tube 602, and ensures their clarity and accuracy. Experimenters can see through the glass outer shell... 601. The liquid volume is read according to the scale lines filled with fluorescent paint. The liquid level sensor 10 also monitors the liquid level in real time. The vacuum cavity 604 between the glass shell 601 and the inner glass tube 602 isolates the temperature, ensuring that the liquid volume is not affected by temperature and that the measurement value is stable and accurate. When the liquid is close to overflowing, it will push the plug 503 upward. When overflowing, the plug 503 is tightly fitted with the liquid guiding channel 502 to prevent liquid backflow. When the liquid level rises to the position of the liquid level sensor 10, the sensor transmits a signal to the external PLC. The PLC automatically controls the opening of the solenoid valve 8 in the sealing sleeve 7. The liquid is discharged through the solenoid valve 8 under the action of gravity. After the liquid level drops, the plug 503 moves away from the liquid guiding channel 502 under the action of the elastic connecting rod 504, and the liquid guiding channel 502 reopens. The liquid collection and measurement work can continue to be carried out in a cycle, ensuring the stability and continuity of liquid collection.
