Description

Technical Field

[0001] This application relates to the field of thermosiphon reboiler technology, and more specifically, to a thermosiphon reboiler. Background Technology

[0002] A Soxhlet extractor, also known as a fat extractor or fat extractor, is a solid-liquid extraction instrument that utilizes solvent reflux and siphon principles to continuously extract solid substances with pure solvent. The Soxhlet extractor consists of three parts: an extraction flask, an extraction tube, and a condenser. The extraction tube has siphon tubes and connecting tubes on both sides, and all connections must be airtight. It is characterized by low solvent consumption and high efficiency. During extraction, the sample to be tested is wrapped in defatted filter paper and placed in the extraction tube. Petroleum ether is added to the extraction flask and heated. The petroleum ether vaporizes and rises through the connecting tube into the condenser, where it condenses and drips into the extraction tube, extracting lipids from the sample. When the petroleum ether level in the extraction tube reaches a certain height, the petroleum ether containing dissolved crude fat flows into the extraction flask through the siphon tube. The petroleum ether in the extraction flask continues to be heated, vaporized, rises, condenses, and drips into the extraction tube, repeating this cycle until extraction is complete.

[0003] The existing extractor has a small heating area in the extraction bottle, resulting in slow sample vaporization, low condensation contact, and slow condensation of the vaporized gas. This leads to low extraction efficiency, low extraction purity, and waste of condensate during the extraction process, thus having shortcomings. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a thermosiphon reboiler, which aims to improve the existing extractors by addressing issues such as small heating area of ​​the extraction bottle, slow sample vaporization rate, small condensation contact volume, slow condensation rate of vaporized gas, resulting in low extraction efficiency, low extraction purity, and waste of condensate during the extraction process.

[0005] This application is implemented as follows:

[0006] This application provides a thermosiphon reboiler comprising:

[0007] An extraction shell is provided, with a concave ring at the bottom and a conical protrusion at the top inner part of the concave ring. A collection bottle is fixedly connected to the bottom inner part of the extraction shell, and a siphon tube is connected to one side of the bottom of the collection bottle. The siphon tube is located inside the extraction shell.

[0008] A dividing plate is fixedly connected to the top of the extraction shell. The dividing plate has multiple through holes that are equidistantly arranged in a ring. A filter component is placed inside the dividing plate.

[0009] The top of the extraction shell is provided with a narrow opening;

[0010] An extraction bottle is provided, with its bottom end sealed to the narrow opening. A spiral condenser is vertically arranged inside the extraction bottle, and a liquid collecting hopper is fixedly connected to the bottom end of the spiral condenser. The top of the liquid collecting hopper is not connected to the bottom of the spiral condenser. The liquid collecting hopper is located directly above the filter component. An inlet pipe and an outlet pipe are fixedly connected to the side wall of the extraction bottle. The inlet pipe is located directly above the outlet pipe, and the inner ends of both the inlet pipe and the outlet pipe are connected to the spiral condenser.

[0011] In one embodiment of this application, the bottom end of the conical protrusion is fixedly connected to a heat inlet conical port.

[0012] In one embodiment of this application, a heating tube is fitted around the outside of the collection bottle, and one end of the heating tube is disposed inside the extraction shell.

[0013] In one embodiment of this application, the other end of the heating tube extends through the bottom of the liquid collection bottle and is connected to the top of the heating inlet conical port.

[0014] In one embodiment of this application, the dividing plate is not provided with a gathering groove, but has an installation groove in the center, and a blocking protrusion is fixedly connected to the installation groove located directly above the heating tube.

[0015] In one embodiment of this application, the filter component includes a filter screen, which is installed in the mounting groove.

[0016] In one embodiment of this application, the bottom of the filter screen is provided with a groove that cooperates with the blocking protrusion.

[0017] In one embodiment of this application, an annular protrusion is provided on the outer edge of the narrow opening.

[0018] In one embodiment of this application, an annular groove is provided on the bottom inner wall of the extraction bottle, and the annular groove is sealed and sleeved with the annular protrusion.

[0019] In one embodiment of this application, the top end of the spiral condenser extends through the top of the extraction bottle.

[0020] The beneficial effects of this application are as follows: A concave ring is provided at the bottom of the extraction shell, and a conical protrusion is provided at the inner top of the concave ring, increasing the heating area at the bottom of the extraction shell. After the concave ring is recessed, the heat will diffuse more quickly inward. A heating conical inlet is fixedly connected to the bottom end of the conical protrusion, which can transfer the hot air in the heat inward. A heating tube is fitted around the outside of the collection bottle. One end of the heating tube is located inside the extraction shell, and the other end of the heating tube passes through the bottom of the collection bottle and is connected to the top of the heating conical inlet. The heating conical inlet directly transfers the transferred hot air into the extraction shell along the heating tube, and part of the heating tube is located inside the collection bottle, thereby liquefying and heating the extract in the collection bottle. This increases extraction efficiency. The conical collecting hopper collects the upward-moving steam, which then condenses and drips onto the filter screen. Alternatively, the rising steam may drip down onto the outer wall of the spiral condenser. Most of the condensate is collected on the filter screen before dripping into the collecting bottle, thus increasing the purity of the extraction. The inner ends of the inlet and outlet pipes are connected to the spiral condenser. When condensate is introduced into the inlet and outlet pipes, it enters the spiral condenser, increasing its condensation effect inside the extraction bottle. This, in turn, drives the collecting hopper to condense the extract. The condensate can be recycled within the inlet, outlet, and spiral condenser, preventing waste. Attached Figure Description

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] like Figures 1-7 As shown, a thermosiphon reboiler according to an embodiment of this application includes:

[0032] The extraction shell 1 has a concave ring 3 at its bottom, and a conical protrusion 4 at the top inner part of the concave ring 3 to increase the heating area at the bottom of the extraction shell 1. After the concave ring 3 is recessed, the heat will diffuse more quickly inward. A heat inlet cone 5 is fixedly connected to the bottom end of the cone 4, which can transfer the hot air in the heat to the inside. A collection bottle 6 is fixedly connected to the bottom of the extraction shell 1. A siphon tube 16 is connected to one side of the bottom of the collection bottle 6. The collection bottle 6 is integrally formed with the extraction shell 1 and the siphon tube 16. The bottom of the collection bottle 6 directly contacts the upper part of the cone 4. The bottom of the collection bottle 6 is arc-shaped towards the center. The concave shape facilitates the collection of the flowing extract. The siphon tube 16 is set inside the extraction shell 1. When the extract in the collection bottle 6 exceeds the upper end of the siphon tube 16, it flows back into the extraction shell 1. The outside of the collection bottle 6 is fitted with a heating tube 7. One end of the heating tube 7 is set inside the extraction shell 1, and the other end of the heating tube 7 passes through the bottom of the collection bottle 6 and is connected to the top of the heating conical inlet 5. The heating conical inlet 5 directly transmits the heat through the heating tube 7 into the extraction shell 1. A part of the heating tube 7 is set inside the collection bottle 6, thereby liquefying and heating the extract in the collection bottle 6 to increase the internal extraction effect.

[0033] A dividing plate 8 is fixedly connected to the top of the extraction shell 1. Multiple through holes 9 are equidistantly arranged in a ring on the dividing plate 8. The evaporation of liquid solvent will be transmitted upward along the through holes 9. A collection groove 17 is provided on the dividing plate 8 to facilitate the collection of condensed extract. An installation groove 10 is provided in the center of the dividing plate 8. A blocking protrusion 11 is fixedly connected in the installation groove 10, which is located directly above the heating tube 7. A filter component is placed inside the dividing plate 8. The filter component includes a filter screen 12. The filter screen 12 is installed in the installation groove 10. A sleeve groove 13 is provided at the bottom of the filter screen 12 to cooperate with the blocking protrusion 11, which facilitates the installation and positioning of the filter screen 12. The filter screen 12 can filter and intercept impurities in the extract. The condensed extract will continuously collect at the filter screen 12 and then drip into the collection bottle 6.

[0034] The top of the extraction shell 1 is provided with a narrow opening 14, and an annular protrusion 15 is provided on the outer edge of the narrow opening 14;

[0035] Extraction bottle 2 has its bottom end sealed to the narrow opening 14. An annular groove 20 is formed on the inner wall of the bottom of extraction bottle 2, and this groove is sealed to an annular protrusion 15 for easy sealing of the entire device. A spiral condenser tube 22 is vertically arranged inside extraction bottle 2, and a collection hopper 21 is fixedly connected to its bottom end for easy positioning. The top of the collection hopper 21 is not connected to the bottom of the spiral condenser tube 22. The collection hopper 21 is positioned directly above the filter element and has a conical structure to collect upward-flowing steam. The steam then condenses and drips onto the filter screen 12. Alternatively, rising steam may drip down the outer wall of the spiral condenser tube 22, but most of the condensate is collected. The extract is collected on the filter screen 12 and then drips into the collection bottle 6. The side wall of the extraction bottle 2 is fixedly connected to an inlet pipe 18 and an outlet pipe 19. The inlet pipe 18 is located directly above the outlet pipe 19. The inner ends of the inlet pipe 18 and the outlet pipe 19 are connected to the spiral condenser 22. When condensing water is introduced into the inlet pipe 18 and the outlet pipe 19, the condensing water will enter the spiral condenser 22, thereby increasing the condensation effect of the spiral condenser 22 inside the extraction bottle 2, which in turn drives the collection hopper 21 to condense the extract. The condensing water can be circulated in the inlet pipe 18, the outlet pipe 19 and the spiral condenser 22 to avoid waste. The top of the spiral condenser 22 extends through the top of the extraction bottle 2 to prevent excessive internal pressure.

[0036] Specifically, the working principle of this thermosiphon reboiler is as follows: A concave ring 3 is provided at the bottom of the extraction shell 1, and a conical protrusion 4 is provided at the top inner part of the concave ring 3 to increase the heating area at the bottom of the extraction shell 1. After the concave ring 3 is recessed, the heat will diffuse more quickly inward. The bottom end of the conical protrusion 4 is fixedly connected to a heating conical inlet 5, which can transfer the hot air in the heat to the inside. A heating tube 7 is sleeved on the outside of the collection bottle 6. One end of the heating tube 7 is placed inside the extraction shell 1, and the other end of the heating tube 7 passes through the bottom of the collection bottle 6 and is connected to the top of the heating conical inlet 5. The heating conical inlet 5 directly transfers the transferred hot air into the extraction shell 1 along the heating tube 7, and part of the heating tube 7 is placed inside the collection bottle 6, thereby heating the extract in the collection bottle 6. The extraction process involves liquefaction heating to increase extraction efficiency. The collection hopper 21, with its conical structure, collects the upward-moving steam, which then condenses and drips onto the filter screen 12. Alternatively, the rising steam may drip down onto the outer wall of the spiral condenser tube 22. Most of the condensate dripping down is collected on the filter screen 12 before dripping into the collection bottle 6. The inner ends of the inlet pipe 18 and the outlet pipe 19 are connected to the spiral condenser tube 22. When condensate is introduced into the inlet pipe 18 and the outlet pipe 19, it enters the spiral condenser tube 22, thereby increasing the condensation effect of the spiral condenser tube 22 inside the extraction bottle 2. This, in turn, drives the collection hopper 21 to condense the extract. The condensate can be recycled within the inlet pipe 18, the outlet pipe 19, and the spiral condenser tube 22, preventing waste.
