[0030] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative embodiments, as would be understood by one skilled in the art. The following exemplary embodiments are described in enough detail to enable those skilled in the art to make and use the application. The examples provided serve only to explain the principles of the application. Other embodiments of the application will be apparent to those skilled in the art from consideration of the description and practice of the application disclosed herein.

[0031] In organic chemical production, there are diverse and strict requirements for the storage and use of liquids. In particular, for high flow rate liquids and high viscosity liquids, there are explicit and stringent regulations for the content of gas bubbles contained in the liquids during storage and use.

[0032] In the prior art, when the medium enters the storage device, due to the presence of a height difference, the medium will obtain a higher flow rate due to potential energy conversion, which can easily lead to the generation of a large number of gas bubbles. The presence of gas bubbles can negatively affect the subsequent use effect, thereby interfering with the normal progress of organic chemical production.

[0033] The present application provides a liquid storage device, such as Figure 1As shown, it comprises a container 1, a partition 2, a plurality of baffles 3, a gas seal assembly 4 and a stirring assembly 5. The container 1 serves as the main body of the whole device. A feed inlet 11 is arranged on the container 1, which is the entrance for liquid into the device. In one embodiment, the feed inlet 11 is located at the upper part of the container 1 and can be arranged on the side wall of the container 1 to facilitate pouring the liquid to be stored into the container 1. The liquid storage device is also provided with a feed passage 12 communicating with the feed inlet 11. The liquid entering the container 1 from the feed inlet 11 can naturally flow into the container 1 from the feed inlet 11 through the feed passage 12 under the action of its own gravity without the aid of additional power equipment, and the liquid filling process is simple, efficient and convenient.

[0034] The container 1 can be made of stainless steel, which has good mechanical strength and corrosion resistance, can withstand large pressure and weight, is suitable for storing liquid with stable properties, and has a smooth surface that is not easy to attach impurities, facilitating cleaning and maintenance. The container 1 can also be made of glass, which has extremely high chemical stability and almost no reaction with any chemical substances, ensuring the purity and properties of the stored liquid are not affected, and has high transparency, facilitating observation of the state of the liquid in the container 1.

[0035] The partition 2 is arranged in the container 1, which divides the container 1 into a feed passage 12 and a storage space 13, and the feed passage 12 communicates with the feed inlet 11 and the storage space 13 respectively. The material of the partition 2 can be the same as that of the container 1, which is stainless steel or glass. Among them, Figure 1 For example, as shown in the orientation in

[0036] In one embodiment, as shown in the vertical direction extending plane in Figure 1 The cross-sectional shape of the partition 2 is L-shaped, the partition 2 is fixed on the inner wall of the container 1, a partition passage is formed between the partition 2 and the inner wall of the container 1, and the space in the container 1 except the partition passage is the storage space 13. In other embodiments, the partition 2 can also be cylindrical and located in the container 1, and the two ends of the partition 2 communicate with the feed inlet 11 and the storage space 13 respectively.

[0037] The plurality of baffles 3 are arranged along a first direction and are staggered in the feed passage 12, the first direction being the extension direction of the feed passage 12, for example, as shown in the orientation in Figure 1The direction shown in the figure is the first direction, which is the vertical direction. When the liquid enters the feeding channel 12 through the feeding port 11, it sequentially contacts the baffles 3 to reduce the flow rate and then enters the storage space 13. The material of the baffles 3 can be the same as that of the container 1, which is stainless steel or glass. In one example, the baffles 3 can be uniformly arranged, and the distance between two adjacent baffles 3 is the same. In another example, the baffles 3 can be arranged in a non-uniform manner, and the distance between two adjacent baffles 3 can be different, so as to irregularly disturb the liquid in the feeding channel 12 and improve the blocking effect.

[0038] Each time the liquid contacts the baffles 3, the flow direction and speed of the liquid are changed. Through multiple collisions and friction with the baffles 3, the flow rate of the liquid can be reduced, effectively solving the problem of bubbles generated due to the high flow rate of the liquid caused by the height difference, reducing bubble generation, and ensuring the storage quality of the liquid.

[0039] The gas sealing assembly 4 is used to deliver protective gas to the container 1 to form a gas protection layer in the container 1, so as to isolate the liquid entering the container 1 from contacting oxygen, thereby protecting the liquid to make it more stable, avoiding oxidation and denaturation of the liquid caused by contact with oxygen, prolonging the storage period of the liquid, ensuring that the quality of the liquid is not affected by oxygen during storage, and avoiding the risk of fire or explosion of the container 1. Before delivering the liquid into the container 1, protective gas is first delivered into the container 1 to fill the container 1, and then the liquid is delivered into the container 1. In order to maintain the constant pressure in the container 1, the liquid can be delivered while the protective gas is discharged outward, so as to fully protect the liquid.

[0040] The stirring assembly 5 is arranged in the storage space 13, and the stirring assembly 5 is used to stir the liquid in the container 1 to make the components of the liquid more uniform and prevent the components in the liquid from precipitating or stratifying. At the same time, stirring also helps to transfer and disperse heat. If heat is generated or needs to be maintained at a certain temperature during storage, the stirring assembly 5 can better achieve uniform distribution of temperature, ensuring the stability and consistency of the liquid during storage. The stirring assembly 5 can be manually driven, and the operator can stir the liquid in the container 1 every certain time interval according to experience or relevant regulations. The stirring assembly 5 can also be electrically driven, and the stirring assembly 5 is connected with a controller to drive the stirring assembly 5 to stir the liquid in the container 1 every preset time interval.

[0041] The present application divides the container 1 into the feeding channel 12 and the storage space 13 by the partition 2, and arranges multiple baffles 3 in the feeding channel 12 in a staggered manner, so that the liquid entering the container 1 contacts the baffles 3 to reduce the flow rate, thereby reducing the bubbles generated due to the high flow rate of the liquid caused by the height difference, and ensuring the storage quality of the liquid.

[0042] The liquid storage device of the present application comprises a container 1, a partition 2, a plurality of baffles 3, a gas sealing assembly 4 and a stirring assembly 5. The container 1 is provided with a feeding port 11. The partition 2 is arranged in the container 1, and the partition 2 divides the container 1 into a feeding channel 12 and a storage space 13, and the feeding channel 12 is in communication with the feeding port 11 and the storage space 13, respectively. The plurality of baffles 3 are arranged in the feeding channel 12 in a first direction, and the first direction is the extension direction of the feeding channel 12. When the liquid enters the feeding channel 12 through the feeding port 11, the liquid sequentially contacts the baffles 3 to reduce the flow rate and then enters the storage space 13. The gas sealing assembly 4 is used for conveying protective gas into the container 1 to isolate the liquid in the container 1 from contacting oxygen. The stirring assembly 5 is arranged in the storage space 13 and is used for stirring the liquid in the container 1.

[0043] In some embodiments, the liquid storage device further comprises a regulating valve 6 arranged on the container 1 and in communication with the storage space 13, and the regulating valve 6 is used for accurately regulating the pressure in the storage space 13. During the liquid storage process, the pressure in the storage space 13 may fluctuate due to various factors such as temperature changes, chemical reactions, etc. The regulating valve 6 can timely adjust the pressure to ensure that the pressure in the storage space 13 is within a safe range. The regulating valve 6 may be a pressure relief valve, and the regulating valve 6 can be connected with a controller. When the pressure in the container 1 is greater than a preset threshold, the controller can control the regulating valve 6 to open to release pressure.

[0044] In some embodiments, the regulating valve 6 is a one-way valve, and the one-way valve is used for discharging the gas in the storage space 13 to reduce the pressure in the storage space 13. The one-way valve is a valve that only allows unidirectional flow. Its working principle is to use the mutual cooperation of valve core, valve seat and other components. When the pressure in the container 1 is high and the gas needs to be discharged, the valve core is opened and the gas passes through smoothly. When the gas enters the container 1 in the opposite direction, the valve core is closed to prevent the gas from entering.

[0045] In the present embodiment, the gas sealing assembly 4 is used for conveying protective gas into the storage space 13, and the one-way valve is used for discharging gas outside the container 1. The gas sealing assembly 4 and the one-way valve cooperate to regulate the pressure in the storage space 13. In addition, because the gas sealing assembly 4 conveys protective gas into the storage space 13, the liquid in the storage space 13 can be kept stable when the pressure in the storage space 13 is regulated, thereby avoiding fire or explosion caused by pressure regulation.

[0046] In some embodiments, the container 1 comprises a barrel and a head. The barrel is in the shape of a cylindrical barrel. The head has two arc-shaped heads arranged at two ends of the barrel. The connection between the head and the container 1 is sealed to prevent the liquid from flowing out.

[0047] The cylindrical shape of the barrel has good stress performance and can uniformly bear the pressure of the internal liquid and the external force. In the case of the same volume, the surface area of the cylindrical container 1 is relatively small, which can reduce the amount of material used and reduce the manufacturing cost. In addition, the space inside the cylindrical container 1 is relatively regular, which is conducive to the flow and stirring of the liquid, and also facilitates the installation and arrangement of other components, such as the partition 2, the baffle 3, the stirring assembly 5, etc. The arc-shaped design of the head has higher strength and better sealing performance than the flat head, and can adapt to higher working pressure and more complex working conditions. At the same time, the arc-shaped head can also form a relatively smooth transition with the barrel, reducing the flow resistance of the liquid inside the container 1, which is conducive to the uniform distribution and stirring of the liquid.

[0048] In some embodiments, the sum of the projection areas of the two adjacent baffles 3 in the first direction is a first area, and the cross-sectional area of the feed channel 12 perpendicular to the first direction is a second area, and the first area is greater than the second area. That is, along the first direction, the projections of the two adjacent baffles 3 in the direction of the bottom surface of the container 1 have overlapping parts, so that the liquid flowing through the feed channel 12 must pass through the disturbance of the baffles to ensure that the baffles 3 can sufficiently reduce the flow rate of the liquid.

[0049] When the liquid flows through the baffles 3, due to the blocking effect of the baffles 3, the flow path of the liquid changes and the flow rate also decreases accordingly. If the sum of the projection areas of the baffles 3 is less than the cross-sectional area of the feed channel 12, the liquid may quickly pass through the gap between the baffles 3, and cannot achieve the effect of effectively reducing the flow rate. When the sum of the projection areas of the baffles 3 is greater than or equal to the cross-sectional area of the feed channel 12, the liquid will receive greater resistance when passing through the baffles 3, and the flow rate will decrease more obviously, thereby better meeting the requirement of the liquid flowing smoothly into the storage space 13.

[0050] In some embodiments, the stirring assembly 5 includes a motor 51, a stirring shaft 52, and a plurality of stirring blades 53. The motor 51 is arranged on the container 1, the output end of the motor 51 is connected with the stirring shaft 52, the stirring shaft 52 is provided with a plurality of stirring blades 53, and the stirring shaft 52 and the stirring blades 53 extend into the storage space 13. The plurality of stirring blades 53 are divided into three groups, and the three groups of stirring blades 53 are arranged along the first direction. Starting the motor 51, the motor 51 drives the stirring shaft 52 to rotate, and the stirring shaft 52 drives the stirring blades 53 to rotate to realize stirring of the liquid. Dividing the stirring blades 53 into three groups can make the stirring more uniform, so that the liquid at different positions can be fully stirred, improve the stirring effect, and better meet the requirements of uniformity of composition and temperature during liquid storage.

[0051] The motor 51 serves as a power source of the stirring assembly 5, and provides power for the rotation of the stirring shaft 52 and the stirring blades 53. The motor 51 is fixed on the top of the container 1, and is connected with the stirring shaft 52 through a shaft coupling.

[0052] The stirring shaft 52 is a key part connecting the motor and the stirring blades 53, and transmits the power of the motor 51 to the stirring blades 53. The stirring shaft 52 has sufficient strength and rigidity to withstand the torque generated by the liquid during stirring, and also ensures stability during rotation to avoid excessive vibration. In addition, the surface of the stirring shaft 52 should be smooth to reduce frictional resistance with the liquid and improve stirring efficiency. In other embodiments, the stirring shaft 52 can also be a hollow structure for installing heating or cooling elements to achieve temperature control of the liquid.

[0053] In some embodiments, the gas sealing assembly 4 includes a gas source (not shown in the figure) for providing protective gas, and a pipeline having two ends respectively communicating with the gas source and the storage space 13 for conveying the protective gas in the gas source to the storage space 13.

[0054] In some embodiments, the protective gas is at least one of nitrogen, carbon dioxide or argon.

[0055] The gas source can be a gas generator, such as a nitrogen generator, a carbon dioxide generator or an argon generator. These generators can produce protective gas on site through chemical reaction or physical method. The gas source can also be a high-pressure gas cylinder, which pre-stores a certain pressure of protective gas, and the gas is conveyed to the pipeline through a pressure reducing valve or other devices during use.

[0056] The pipeline can be made of at least one of stainless steel and polytetrafluoroethylene. In some embodiments, some control devices such as valves, flow meters and pressure gauges are provided on the pipeline to realize precise control and detection of the protective gas conveying process. By providing a valve, the flow of protective gas can be controlled. By providing a flow meter, the flow of gas can be monitored in real time to ensure the stability of gas supply. By providing a pressure gauge, the pressure in the pipeline can be known to prevent damage to the container 1 or the pipeline caused by excessive or insufficient pressure.

[0057] In some embodiments, the baffle 3 is perpendicular to the first direction, which can maximize the contact area of the liquid with the baffle 3 after entering the feed channel 12, so that the flow rate of the liquid can be reduced to the greatest extent under the blocking action of the baffle 3. When the liquid vertically impacts the baffle 3, its kinetic energy will be effectively absorbed and dispersed by the baffle 3, so that the flow direction of the liquid changes, forming eddy current and backflow, further reducing the flow rate of the liquid, so that the liquid flows smoothly into the storage space 13, avoiding excessive impact and wear on the bottom of the container 1.

It is intended that the application embrace any and all variations of the present application that fall within the scope of the general inventive concept as defined in the claims and that the specification and examples be considered exemplary only in nature.
