Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, specifically to a special extraction device for residual fat rate of down feathers. Background Technology

[0002] In standards such as the oil content test method for chemical fibers and the inspection method for down and feathers, a Soxhlet extractor is used for reflux extraction to extract substances such as oils.

[0003] Currently, the Soxhlet extractor and water bath are combined into one device. The water bath is used to heat the distillation flask in the Soxhlet extractor, and the water bath provides the temperature required for the solvent in the distillation flask to boil. The Soxhlet extractor is then used for reflux purification.

[0004] Different test conditions require different numbers of solvent refluxes. During the test, the experimenter needs to manually observe and count the number of refluxes. Based on the interval between the first and second refluxes, the achievable reflux frequency per hour can be inferred. If it is too fast, the temperature of the water bath needs to be lowered to reduce the boiling rate; if it is too slow, the temperature of the water bath needs to be increased to accelerate the boiling rate.

[0005] The adjustment process is cumbersome and takes up a lot of the experimenter's time. Even if the water bath temperature is adjusted to a suitable level, it is impossible to ensure that the actual number of refluxes in the entire process meets the requirements, which involves a lot of uncertainty. Utility Model Content

[0006] The purpose of this invention is to provide a special extraction device for down residual fat rate. It uses an external liquid level gauge to sense the liquid level in the siphon tube and thus senses the reflux process. The controller adjusts the water bath heating temperature accordingly. This eliminates the need for real-time monitoring and counting by the experimenter, making it more convenient and improving the accuracy of the extraction experiment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a special extraction device for residual fat rate of down feathers, including multiple sock extractors and a water bath heating component for heating them. The sock extractor includes an extractor and a siphon tube fixed on one side of the extractor. An external liquid level gauge is provided at the highest point of the outermost end of the siphon tube, which can sense when the liquid level reaches the reflux height.

[0008] The water bath heating assembly is equipped with a control panel and an alarm on the front side. A touch screen is fixedly installed on the front side of the control panel. The control panel has a built-in controller, electronic timing module, counting sensor and network module.

The cameras are located directly behind the corresponding Soxhlet extractors. The cameras are located at the input end of the controller, and the water bath pot is located at the output end of the controller.

[0011] Furthermore, the Soxhlet extractor also includes a condenser located at the top of the extractor, with a sealed connection between the extractor and the condenser. The outer end of the condenser is provided with an inlet and an outlet for condensate water, and a fixing clip is provided at the outer end of the condenser. The rear end of the fixing clip is connected to the front side of the back plate.

[0012] A steam conduit is fixedly provided on the other side of the extractor, and an insulating rubber sleeve is fitted over the outer end of the steam conduit.

[0013] Furthermore, the extractor is equipped with a distillation flask at its bottom, which is located inside a water bath. The water in the water bath covers the solvent in the distillation flask, and the top of the distillation flask extends to the top of the water bath.

[0014] Furthermore, the top of the water bath is provided with two cover plates that serve a sealing function. Multiple external holes are provided at the joint between the two cover plates. These external holes correspond one-to-one with the distillation flasks and are fitted onto the neck of the corresponding distillation flasks.

[0015] The external connection hole is divided into two semi-circular grooves, which are respectively opened on the two cover plates. A rubber strip that plays a sealing role is fixed on the inner wall of the semi-circular groove. The rubber strip contacts the neck of the corresponding distillation flask.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-5 The device shown is a special extraction device for residual fat rate of down feathers, including multiple sock extractors and a water bath heating component 2 for heating them. The sock extractor includes an extractor 6 and a siphon tube 12 fixed to one side of the extractor 6. An external liquid level gauge 14 is provided at the highest point of the outermost end of the siphon tube 12, which can sense when the liquid level reaches the reflux height.

[0030] The water bath heating assembly 2 is provided with a control panel 7 and an alarm 9 on the front side. The control panel 7 is fixedly provided with a touch screen 8 on the front side. The control panel 7 has a built-in controller 15, an electronic timing module 16, a counting sensor 17 and a network module 18. The touch screen 8 can display parameters such as the number of reflows, the experimental time and the water bath heating temperature. The touch screen 8 can also be used to set the number of reflows, the experimental time and other parameters via touch.

[0031] The external liquid level gauge 14 is located at the input end of the counting sensor 17. The electronic timing module 16 and the counting sensor 17 are both located at the input end of the controller 15. The touch screen 8 and the network module 18 are both located at the connection end of the controller 15. The alarm 9 is located at the output end of the controller 15. The network module 18 can upload relevant parameters during the extraction process to the network. Experimenters can remotely obtain data from the network and conduct remote monitoring through devices such as mobile phones and computers.

[0032] The residual fat in down is extracted using a Soxhlet extractor, and the residual fat rate is calculated using the extracted residual fat. During the extraction process, the extraction solvent is heated by a water bath heating component 2. After the solvent is heated and evaporated, it condenses and drips into the extractor 6. The solvent is extracted in the extractor 6. The liquid level inside the extractor 6 rises continuously, and the liquid level inside the siphon tube 12 rises synchronously. When the liquid level inside the siphon tube 12 reaches its highest point, the solvent containing the residual fat inside the extractor 6 flows back through the siphon tube 12 under the action of the siphon principle. This cycle is repeated until the residual fat is fully extracted.

[0033] During the extraction process described above, the reflux condition is met when the liquid level reaches the highest point of the siphon tube 12. Simultaneously with the start of reflux, the external level gauge 14 senses the liquid level height in the siphon tube 12 and transmits the signal to the controller 15 via the counting sensor 17. The counting sensor 17 calculates the number of refluxes and displays the number of refluxes on the touch screen display 8 under the control of the controller 15. At the same time, the electronic timing module 16 keeps time during extraction. If the number of refluxes is too frequent, the controller 15 lowers the water bath temperature; conversely, if the reflux rate is too slow, the controller 15 raises the water bath temperature. When the set number of refluxes is reached, the controller 15 stops the water bath heating, thus stopping the experiment. This eliminates the need for real-time monitoring and counting by the experimenter, making it more convenient and improving the accuracy of the extraction experiment. In special circumstances such as prolonged periods without reflux, the controller 15 can stop heating and trigger an alarm via the alarm 9, thus reminding the experimenter to terminate the experiment in a timely manner and ensuring its safe and normal operation.

[0034] In addition to understanding the relevant data, it also allows for remote observation of the extraction process, such as... Figure 1 , 5 As shown, the water bath heating assembly 2 includes a water bath 201. A base 1 is fixedly provided at the bottom of the water bath 201, and a back plate 3 is fixedly provided at the top of the base 1. All Soxhlet extractors are located on the front side of the back plate 3. Multiple cameras 4 corresponding to the Soxhlet extractors are fixedly provided on the front side of the back plate 3. The cameras 4 are located directly behind the corresponding Soxhlet extractors. The cameras 4 are located at the input end of the controller 15, and the water bath 201 is located at the output end of the controller 15.

[0035] The water used for heating the water bath of the Soxhlet extractor is stored in the water bath 201 and heated by the water bath 201. The controller 15 can control the start or stop of heating and adjust the heating temperature by controlling the water bath 201. The camera 4 can capture images of the Soxhlet extractor during the extraction process from the rear and upload the captured images through the controller 15 and the network module 18. Experimenters can obtain the captured images through mobile phones, computers and other devices for remote visual observation.

[0036] The Soxhlet extractor needs to be fixed in place, such as... Figure 1-3 As shown, the Soxhlet extractor also includes a condenser 5 located at the top of the extractor 6. The extractor 6 and the condenser 5 are sealed together. The outer end of the condenser 5 is provided with an inlet and an outlet for condensate. The outer end of the condenser 5 is provided with a fixing clip. The rear end of the fixing clip is connected to the front side of the back plate 3.

[0037] A steam conduit 11 is fixedly provided on the other side of the extractor 6, and a heat-insulating rubber sleeve 13 is fitted on the outer end of the steam conduit 11.

[0038] The extractor 6 is provided with a distillation flask 10 at the bottom. The distillation flask 10 is located inside the water bath 201. The water in the water bath 201 covers the solvent in the distillation flask 10. The top of the distillation flask 10 extends to the top of the water bath 201.

[0039] The inner wall of the water bath 201 is provided with a detachable support net 202. The support net 202 has positioning holes 203 that correspond one-to-one with the distillation flask 10. The diameter of the positioning hole 203 is smaller than the diameter of the body of the distillation flask 10. The bottom end of the distillation flask 10 is embedded in the corresponding positioning hole 203.

[0040] The main body of the Soxhlet extractor consists of a distillation flask 10, an extractor 6, and a condenser 5, from bottom to top. These three parts are connected end to end and sealed. The extractant is stored in the distillation flask 10, which is spherical in shape. To ensure stability in the water bath 201, the bottom of the distillation flask 10 is embedded in the positioning hole 203 on the support net 202. Thus, the distillation flask 10 is supported by the support net 202. The condenser 5 is connected to the back plate 3 by a fixing clamp, thereby stabilizing the Soxhlet extractor from both ends. During the water bath heating process, the solvent in the distillation flask 10 evaporates and flows upward through the steam conduit 11, eventually condensing in the condenser 5. The heat-insulating rubber sleeve 13 at the outer end of the steam conduit 11 keeps the solvent vapor warm during its upward conduction, preventing it from condensing before reaching the condenser 5 and thus avoiding a reduction in extraction efficiency.

[0041] To reduce the interference of steam in the water bath 201, such as Figure 1 , 2 As shown, the top of the water bath 201 is provided with two cover plates 204 that serve a sealing function. Multiple external holes are provided at the joint of the two cover plates 204. These external holes correspond one-to-one with the distillation flask 10 and are fitted onto the neck of the corresponding distillation flask 10.

[0042] The external connection hole is divided into two semi-circular grooves 205, which are respectively opened on two cover plates 204. A rubber strip is fixed on the inner wall of the semi-circular groove 205 to play a sealing role. The rubber strip contacts the neck of the corresponding distillation flask 10. A guide tube 206 is fixed on the top of each of the two cover plates 204.

[0043] During the water bath process, the hot water inside the water bath 201 easily generates water mist. The water mist obstructs the view during the extraction process, and the upward-drifting water mist adheres to the surface of the Soxhlet extractor. The condenser 5 absorbs the heat from the water mist, affecting the condensation efficiency of the condenser 5. Therefore, the distillation flask 10 is placed in the water bath 201 with its top extending upwards. At the same time, the opening of the water bath 201 is sealed by the cover plate 204. The steam and water mist in the water bath 201 are guided through the guide tube 206 to avoid water mist interfering with the view and to prevent water mist from reducing the condensation efficiency.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
