Description

Technical Field

[0001] The utility model belongs to the field of alcohol precipitation tank equipment, and particularly relates to a liquid inlet and liquid distribution device. Background Art

[0002] In the alcohol precipitation process, the effective volume of the alcohol precipitation tank commonly used is 2000L. Figure 1-2 As shown, the current ethanol inlet and distribution device used in the alcohol precipitation process is a straight pipe with a length of 350 mm and a diameter of 25 mm, and 336 ethanol dripping holes with a diameter of 1 mm are arranged on the straight pipe. However, due to the short length of this straight pipe, the diameter of the ethanol dripping holes is small and the hole spacing is large, resulting in a small contact area when the ethanol is dripped. This further leads to uneven mixing of the ethanol with the liquid medicine during dripping, and easily produces a large amount of fibrous material that entangles with the agitator inside the alcohol precipitation tank and cannot fall off. This in turn affects production efficiency and causes large material losses, further affecting the final product yield.

[0003] Therefore, a new type of ethanol liquid inlet and liquid distribution device is urgently needed to solve the current problem. Utility Model Content

[0004] The utility model aims to overcome the defects in the prior art of using an ethanol liquid feeding and distributing device in an alcohol precipitation process, in which ethanol is unevenly mixed with a medicinal liquid when added dropwise, and a large amount of fibrous matter is easily produced which adheres to an agitator and is difficult to separate. A liquid feeding and distributing device is provided to overcome the above defects.

[0005] In order to achieve the above-mentioned purpose of the invention, the present invention is implemented through the following technical solutions:

[0006] A liquid inlet and liquid distribution device, comprising:

[0007] A liquid inlet pipe is provided inside the alcohol precipitation tank, wherein the upper end of the liquid inlet pipe passes through the top of the alcohol precipitation tank and extends upward;

[0008] A liquid distribution assembly is arranged at the lower end of the liquid inlet pipe and is connected thereto. The liquid distribution assembly includes a first liquid distribution pipe connected to the lower end of the liquid inlet pipe and a second liquid distribution pipe away from the lower end of the liquid inlet pipe. The bottoms of the first liquid distribution pipe and the second liquid distribution pipe are both provided with a plurality of leakage holes for liquid outflow.

[0009] The utility model includes a liquid inlet pipe disposed within an alcohol precipitation tank, the upper end of which penetrates the top of the alcohol precipitation tank and extends upward. The utility model also includes a liquid distribution assembly disposed at and connected to the lower end of the liquid inlet pipe. The liquid distribution assembly includes a first liquid distribution pipe connected to the lower end of the liquid inlet pipe and a second liquid distribution pipe remote from the lower end of the liquid inlet pipe. The bottoms of the first and second liquid distribution pipes are each provided with a plurality of leakage holes for liquid discharge.

[0010] The utility model is provided with a liquid distribution component and orderly arranged leakage holes at the bottom of the first liquid distribution pipe and the second liquid distribution pipe, which helps to evenly distribute ethanol on the surface of the solution when it enters the liquid, promotes the uniform mixing of ethanol with the liquid medicine when it is added dropwise, effectively avoids the generation of fibrous materials or adhesion to the agitator inside the alcohol precipitation tank, further avoids material loss, and improves production efficiency. The utility model is designed with uniquely arranged leakage holes and further improves the leakage hole diameter and hole spacing, effectively increasing the contact area when ethanol is added dropwise, so that ethanol can be evenly added dropwise to the solution and fully mixed with the solution, effectively preventing too many long flocs caused by uneven ethanol addition during alcohol precipitation and entanglement and stirring, further improving product yield. The utility model has a simple structure and low cost, which is conducive to promotion and application in production practice.

[0011] Preferably, the upper end of the liquid inlet pipe is connected to the top of the alcohol precipitation tank via a chuck interface.

[0012] This arrangement helps ensure a tight and reliable connection between the liquid inlet pipe and the alcohol precipitation tank, preventing liquid leakage and thus enhancing the connection stability of the device. Furthermore, the chuck interface design facilitates installation and removal, facilitating subsequent cleaning, maintenance, or replacement of the liquid inlet pipe.

[0013] Preferably, the lower end of the liquid inlet pipe and the upper end of the first liquid distribution pipe are detachably connected.

[0014] The detachable connection method makes it easy to install and facilitate subsequent maintenance, which helps to extend its service life.

[0015] Preferably, the lower end of the liquid inlet pipe and the upper end of the first liquid distribution pipe are connected via a first union.

[0016] This arrangement facilitates installation and disassembly, while also helping to maintain the overall stability and safety of the device. Furthermore, unions are typically made of high-strength, corrosion-resistant materials, which can better protect the piping system from damage, thereby extending the service life of the entire piping system.

[0017] Preferably, the cross-sections of the first liquid distribution pipe and the second liquid distribution pipe are both semi-annular.

[0018] The semi-circular cross-sectional design provides the liquid distribution pipe with a larger radial expansion area, thereby better dispersing and evenly distributing the liquid and improving distribution uniformity. It also optimizes the pressure distribution of the liquid within the pipe, reducing erosion and wear on the pipe, thereby extending the pipe's service life. Furthermore, the semi-circular cross-sectional design allows for greater radial flexibility between the two liquid distribution pipes, enabling them to better adapt to different spatial layouts and arrangements, thereby helping to improve space utilization.

[0019] Preferably, the first liquid distribution pipe and the second liquid distribution pipe are connected via a second union.

[0020] The above arrangement facilitates installation and disassembly, and helps to enhance the connection strength and sealing between the first liquid distribution pipe and the second liquid distribution pipe.

[0021] Preferably, the leakage holes provided at the bottom of the first liquid distribution pipe and the second liquid distribution pipe are arranged at equal intervals.

[0022] As a further preference, the leakage holes provided at the bottom of the first liquid distribution pipe and the second liquid distribution pipe have a diameter of 1-2 mm.

[0023] Equally spaced leak holes help ensure even distribution and drainage of liquid at the bottom of the two distribution pipes, further improving distribution uniformity. This ensures even mixing of the liquid with the drug solution during dripping, effectively preventing the formation of long flocs or fibers that could entangle or adhere to the agitator inside the alcohol precipitation tank, thereby improving product yield.

[0024] Preferably, the leakage hole is elliptical, and the angle between the long axis of the leakage hole and the vertical direction is 8-10°.

[0025] Compared to circular holes, the elliptical leak design can better guide liquid flow, reduce turbulence and eddy currents, and help improve the efficiency and stability of liquid flow. At the same time, by adjusting the angle between the long axis of the leak and the vertical direction, the distribution of liquid at the bottom of the two liquid distribution pipes can be further optimized, allowing the liquid to mix more evenly with the drug solution as it flows out of the leak, improving liquid distribution uniformity. Furthermore, the elliptical leak has a larger opening area, effectively increasing the contact area between the liquid and the drug solution during dripping.

[0026] Therefore, the utility model has the following beneficial effects:

[0027] (1) The utility model provides a liquid distribution component and orderly arranged leakage holes at the bottom of the first liquid distribution pipe and the second liquid distribution pipe, which helps to evenly distribute ethanol on the surface of the solution when it is added, and promotes uniform mixing of ethanol with the liquid medicine when it is added, effectively avoiding the generation of fibrous substances or adhesion to the agitator inside the alcohol precipitation tank, further avoiding material loss and improving production efficiency; (2) The utility model effectively increases the contact area when ethanol is added by designing uniquely arranged leakage holes and further improving the leakage hole diameter and hole spacing, so that ethanol can be evenly added to the solution and fully mixed with the solution, effectively preventing too many long flocs and entanglement and stirring caused by uneven ethanol addition during alcohol precipitation, and further improving product yield;

[0028] (3) The utility model has a simple structure and low cost, which is conducive to its promotion and application in production practice. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example 1

[0037] like Figure 3-5 As shown, the present invention includes a liquid inlet pipe 1 disposed within an alcohol precipitation tank 2. The upper end of the liquid inlet pipe 1 penetrates the top of the alcohol precipitation tank 2 and extends upward. It also includes a liquid distribution assembly 3 disposed at and connected to the lower end of the liquid inlet pipe 1. The liquid distribution assembly 3 includes a first liquid distribution pipe 4 connected to the lower end of the liquid inlet pipe 1 and a second liquid distribution pipe 5 remote from the lower end of the liquid inlet pipe 1. The bottoms of both the first and second liquid distribution pipes 4, 5 are provided with a plurality of leakage holes 6 for liquid outflow.

[0038] The utility model is provided with a liquid distribution component 3 and a leak hole 6 arranged in an orderly manner at the bottom of the first liquid distribution pipe 4 and the second liquid distribution pipe 5, which helps to evenly distribute the solution surface when ethanol is fed, promotes ethanol to be mixed evenly with the liquid when it is added dropwise, effectively avoids fibrous material from being generated or adhering to the agitator inside the alcohol precipitation tank 2, further avoids material loss, and improves production efficiency. The utility model is designed with a unique arrangement of the leak holes 6 and further improves the leak hole 6 diameter and the hole spacing, effectively increases the contact area when ethanol is added dropwise, so that ethanol can be evenly added dropwise to the solution and fully mixed with the solution, effectively preventing too many long flocs caused by uneven ethanol addition during alcohol precipitation, and entanglement and stirring, further improving product yield. The utility model is simple in structure and low in cost, and is conducive to promotion and application in production practice.

[0039] As an embodiment, the upper end of the liquid inlet pipe 1 is connected to the top of the alcohol precipitation tank 2 via a chuck interface 7 .

[0040] The above arrangement helps ensure a tight and reliable connection between the liquid inlet pipe 1 and the alcohol precipitation tank 2, preventing liquid leakage, thereby helping to enhance the connection stability of the device. At the same time, the design of the chuck interface 7 facilitates installation and removal, which is beneficial for later cleaning, maintenance, or replacement of the liquid inlet pipe 1.

[0041] As an embodiment, the lower end of the liquid inlet pipe 1 and the upper end of the first liquid distribution pipe 4 are detachably connected.

[0042] The detachable connection method makes it easy to install and facilitate subsequent maintenance, which helps to extend its service life.

[0043] As an embodiment, the lower end of the liquid inlet pipe 1 and the upper end of the first liquid distribution pipe 4 are connected via a first union 8 .

[0044] This arrangement facilitates installation and disassembly, while also helping to maintain the overall stability and safety of the device. Furthermore, unions are typically made of high-strength, corrosion-resistant materials, which can better protect the piping system from damage, thereby extending the service life of the entire piping system.

[0045] As an embodiment, the cross-sections of the first liquid distribution pipe 4 and the second liquid distribution pipe 5 are both semi-annular.

[0046] The semi-circular cross-sectional design provides the liquid distribution pipe with a larger radial expansion area, thereby better dispersing and evenly distributing the liquid and improving distribution uniformity. It also optimizes the pressure distribution of the liquid within the pipe, reducing erosion and wear on the pipe, thereby extending the pipe's service life. Furthermore, the semi-circular cross-sectional design allows for greater radial flexibility between the two liquid distribution pipes, enabling them to better adapt to different spatial layouts and arrangements, thereby helping to improve space utilization.

[0047] As an embodiment, the first liquid distribution pipe 4 and the second liquid distribution pipe 5 are connected via a second union 9 .

[0048] The above arrangement facilitates installation and disassembly, and helps to enhance the connection strength and sealing between the first liquid distribution pipe 4 and the second liquid distribution pipe 5.

[0049] As an embodiment, the leakage holes 6 provided at the bottom of the first liquid distribution pipe 4 and the second liquid distribution pipe 5 are arranged at equal intervals.

[0050] As another embodiment, the leakage holes 6 provided at the bottom of the first liquid distribution pipe 4 and the second liquid distribution pipe 5 have a hole diameter of 1 to 2 mm.

[0051] The equally spaced holes 6 help ensure that the liquid is evenly distributed and drained from the bottom of the two liquid distribution pipes, further improving liquid distribution uniformity. This ensures that the liquid is evenly mixed with the drug solution during dropwise addition, effectively preventing the formation of long flocculent or fibrous matter that would entangle or adhere to the agitator inside the alcohol precipitation tank 2, thereby improving product yield.

[0052] As an embodiment, the leakage hole 6 is elliptical, and the angle between the long axis of the leakage hole 6 and the vertical direction is 8-10 degrees.

[0053] Compared to circular holes 6, the elliptical design of the leak hole 6 can better guide liquid flow, reduce turbulence and eddy currents, and help improve the efficiency and stability of liquid flow. Furthermore, by adjusting the angle between the long axis of the leak hole 6 and the vertical direction, the distribution of liquid at the bottom of the two liquid distribution pipes can be further optimized, allowing the liquid to mix more evenly with the liquid medicine upon exiting the leak hole 6, improving liquid distribution uniformity. Furthermore, the elliptical hole 6 has a larger opening area, effectively increasing the contact area between the liquid and the liquid medicine during dripping.

[0054] The working principle of this utility model is as follows:

[0055] Insert the liquid inlet pipe 1 into the interior of the alcohol precipitation tank 2 from top to bottom and connect the upper end of the liquid inlet pipe 1 to the top of the alcohol precipitation tank 2 through the chuck interface 7. Connect the first liquid distribution pipe 4 and the second liquid distribution pipe 5 through the second union 9, and then connect the lower end of the liquid inlet pipe 1 to the upper end of the first liquid distribution pipe 4 through the first union 8. After installation, drip ethanol liquid from the upper end of the liquid inlet pipe 1 into the alcohol precipitation tank 2, so that ethanol flows into the two liquid distribution pipes from the liquid inlet pipe 1 and flows out from the leakage hole 6 provided at the bottom of the first liquid distribution pipe 4 and the second liquid distribution pipe 5, so that ethanol can be evenly added dropwise to the alcohol precipitation tank 2 and fully mixed with the medicinal liquid in the alcohol precipitation tank 2.
