Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to a secondary steam supply component for an extraction device. Background Technology

[0002] In the pharmaceutical industry, extraction tanks are crucial leaching and extraction equipment used to extract active ingredients from raw materials such as plants. Typically, the solvent and raw material come into contact within the tank, which is heated by an electric heating system to leach out the active ingredients, resulting in a pure herbal extract. The extracted liquid is then filtered and concentrated through evaporation. During the evaporation and concentration stage, a large amount of steam is generated in the evaporation chamber. In existing technologies, this steam is used to heat water after heat exchange and is then used in other pharmaceutical processes. However, due to the continuous production and inability to store the steam, coupled with the limited demand for hot water, a large amount of hot steam is emitted during actual operation, resulting in significant energy waste. This energy waste not only increases production costs but also has adverse environmental impacts. Therefore, how to effectively utilize this secondary steam and improve energy efficiency has become a pressing issue for the pharmaceutical industry. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a secondary steam supply component for an extraction device, which solves the problem of hot steam waste in the existing evaporation and concentration process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a secondary steam supply component for an extraction device, comprising an extraction tank, an evaporation chamber, and a steam delivery pipe connecting the evaporation chamber and the extraction tank. One end of the steam delivery pipe, inserted into the extraction tank, is rotatably connected to an outlet pipe. A gap exists between the bottom of the outlet pipe and the bottom of the extraction tank. The outlet pipe includes a hollow bridging component and a first wall and a second wall connected to the bridging component. The first wall and the second wall are positioned opposite each other on the bridging component, and a gap is formed between them.

[0005] Nozzles are tangentially arranged on the sidewalls of the first and second walls, and the nozzles on the first and second walls face opposite directions.

[0006] Preferably, the cross-sections of the first wall and the second wall are both arc-shaped, so that the inner side of the gap between them forms a circular cavity.

[0007] Preferably, the clamping cavity is coaxial with the gas outlet pipe, and the gas outlet pipe is coaxial with the steam conveying pipe.

[0008] Preferably, there are multiple nozzles, which are spaced apart along the setting direction of the first wall and the second wall, and the nozzle openings of the multiple nozzles gradually increase in size from top to bottom.

[0009] Preferably, the nozzle includes a first jet nozzle and a second jet nozzle disposed above and below the first wall and the second wall, respectively, wherein the nozzle opening of each second jet nozzle is larger than the nozzle opening of the first jet nozzle.

[0010] Preferably, the nozzle of the first jet nozzle is hollow.

[0011] Preferably, the nozzle of the second jet nozzle is provided with a cap, and the surface of the cap is evenly distributed with a plurality of openings.

[0012] Preferably, the cap and the second air nozzle are detachably connected.

[0013] Preferably, the extraction tank is further provided with a retainer for fixing the steam delivery pipe and the gas outlet pipe.

[0014] Preferably, the retainer has an upper positioning ring and a lower positioning ring; the steam conveying pipe is fixed on the upper positioning ring, and the steam outlet pipe is rotatably connected to the lower positioning ring.

[0015] The beneficial effects of this invention are as follows: By using the secondary steam supply component of the extraction equipment provided by this invention, a large amount of steam generated in the evaporation chamber is collected and returned to the extraction tank as a heat source through a steam delivery pipeline. This heats the solvent inside the extraction tank, assisting the electric heating system of the extraction tank itself in heating the solvent inside the tank, thereby saving the heat output of the electric heating system and reducing energy consumption. Furthermore, the steam outlet pipe can be driven to rotate by the ejected steam, allowing the steam to be evenly input into the solvent in multiple streams, achieving uniform heating within the solvent and improving extraction efficiency. This method improves energy utilization efficiency, reduces energy waste, and lowers production costs. Attached Figure Description

[0025] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. This utility model discloses a secondary steam supply component for an extraction device, including a steam delivery pipe connecting an evaporation chamber and an extraction tank. One end of the steam delivery pipe, inserted into the extraction tank, is rotatably connected to an outlet pipe. The outlet pipe includes a hollow bridging component and a first wall and a second wall connected to the bridging component. Nozzles are tangentially arranged on the side walls of the first and second walls. A large amount of steam generated in the evaporation chamber is collected and returned to the extraction tank as a heat source through the steam delivery pipe, heating the solvent within the extraction tank. Furthermore, the outlet pipe can be driven to rotate by the ejected steam, causing the steam to be uniformly input into the solvent in multiple streams, achieving internal heating of the solvent and uniformly increasing its temperature, thereby improving extraction efficiency.

[0026] The technical solutions of the present invention 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 invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0027] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0028] like Figures 1 to 7 As shown, the secondary steam supply assembly proposed in this application includes an extraction tank 1, an evaporation chamber 2, and a steam delivery pipe 3 connecting the evaporation chamber 2 and the extraction tank 1, supplying secondary steam generated in the evaporation chamber 2 into the extraction tank 1. The steam delivery pipe 3 is equipped with a centrifugal steam compressor, a pressure gauge, and a solenoid valve (not shown in the figure) to control the pressure and delivery time within the steam delivery pipe 3. The installation of a centrifugal steam compressor, pressure gauge, and solenoid valve on the pipe is known technology and will not be elaborated upon here.

[0029] In this embodiment, the steam conveying pipeline 3 recovers the hot steam and returns it to the extraction tank 1 as a heat source to heat the solvent in the extraction tank 1. This assists the electric heating system of the extraction tank 1 in heating the solvent inside the tank 1, saving the heat output of the electric heating system, and achieving heating inside the solvent to improve extraction efficiency.

[0030] like Figure 2 As shown, the steam delivery pipe 3 is inserted into the extraction tank 1 and rotatably connected to the outlet pipe 4. There is a gap between the bottom of the outlet pipe 4 and the bottom of the extraction tank 1. The extract to be extracted is placed in this space. During use, it is ensured that the outlet pipe 4 is immersed in the solvent and that the bottom does not contact the extract to ensure normal gas output from the outlet pipe 4.

[0031] like Figure 2 and Figure 7 As shown, in order to improve the stability of the steam conveying pipe 3 and the gas outlet pipe 4 during use, a retainer 14 is also provided in the extraction tank 1 to fix the steam conveying pipe 3 and the gas outlet pipe 4.

[0032] For example, the retainer 14 has an upper positioning ring 15 and a lower positioning ring 16, which are spaced apart. The steam conveying pipe 3 is fixed to the upper positioning ring 15. At this time, the connection between the steam conveying pipe 3 and the extraction tank 1 is a first fixed point, and the connection with the upper positioning ring 15 is a second fixed point. The dual-point fixation enhances the stability of the steam conveying pipe 3 during use and prevents damage or cracks from pipe vibration or shaking caused by steam conveying, which could result in damage or cracks at the connection with the extraction tank 1 or the exhaust pipe 4. In addition, the exhaust pipe 4 is rotatably connected to the lower positioning ring 16. At this time, the rotatable connection between the exhaust pipe 4 and the steam conveying pipe 3 is a first rotatable connection point, and the rotatable connection with the lower positioning ring 16 is a second rotatable connection point. The dual-point connection enhances the stability of the exhaust pipe 4 during use.

[0033] Specifically, in this embodiment, the air outlet pipe 4 is as follows: Figure 3 As shown, it includes a hollow bridging component 7 and a first wall 5 and a second wall 6 connected to the bridging component 7. The bridging component 7 is rotatably connected to the steam conveying pipe 3 via a rotating ring. The first wall 5 and the second wall 6 are arranged opposite to each other on the bridging component 7, and a gap 10 is formed between them. This gap 10 allows the solvent to flow inside, increasing the heat exchange effect between the gas outlet pipe 4 and the solvent.

[0034] Furthermore, such as Figure 3 and Figure 4As shown, nozzles are tangentially arranged on the side walls of the first wall 5 and the second wall 6, and the nozzles on the first wall 5 and the second wall 6 face opposite directions. The pressure of the steam transported in the steam transport pipeline 3 is controlled by a pressure gauge and a solenoid valve. When a certain pressure is reached, the gas is ejected through the nozzles in both directions, causing the gas outlet pipeline 4 to rotate slowly and continuously in the solvent liquid. This allows the steam to enter the solvent liquid while rotating, uniformly heating the solvent.

[0035] Furthermore, the cross-sections of the first wall 5 and the second wall 6 are both arc-shaped, forming a circular cavity 11 inside the gap 10 between them. The cavity 11 is coaxial with the gas outlet pipe 4, and the gas outlet pipe 4 is coaxial with the steam conveying pipe 3. With this design, when the gas outlet pipe 4 rotates, the arc-shaped first wall 5 and the second wall 6 can reduce the resistance to contact with the solvent during rotation.

[0036] Furthermore, in this embodiment, there are multiple nozzles, such as... Figure 3 As shown, multiple nozzles are spaced apart along the length of the first wall 5 and the second wall 6, with the nozzle openings gradually increasing in size from top to bottom. This ensures that when steam is output from top to bottom, it is first ejected from the nozzle with the smaller opening, guaranteeing that the gas outlet pipe 4 has sufficient gas ejection power. The diameter of the nozzle at the top must not exceed 5mm, and the diameter of the nozzle at the bottom must not exceed 1cm.

[0037] Specifically, the nozzles include a first jet nozzle 8 and a second jet nozzle 9 disposed above and below the first wall 5 and the second wall 6, respectively, with the nozzle opening of each second jet nozzle 9 being larger than that of the first jet nozzle 8. For example, there are two first jet nozzles 8 with nozzle diameters of 3mm and 4mm, respectively. There are two second jet nozzles 9 with nozzle diameters of 6mm and 8mm, respectively.

[0038] In this embodiment, as Figure 5 and Figure 6 As shown, the nozzle of the first jet nozzle 8 is hollow. The nozzle of the second jet nozzle 9 is provided with a cover 12, and the surface of the cover 12 is evenly distributed with a number of openings 13 to allow steam to enter the solvent in the form of small gas streams.

[0039] Furthermore, in this embodiment, the cap 12 and the second nozzle 9 are detachably connected, allowing for selective use of the cap 12 or removal of the cap 12 to clear the blockage opening 13. Specifically, the cap 12 and the second nozzle 9 are connected by screws or clips.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
