Description

Technical Field

[0001] This utility model relates to the field of chemical experimental instrument technology, and in particular to a feeding auxiliary structure for a Soxhlet extractor. Background Technology

[0002] A Soxhlet extractor is a device used to extract compounds from solid substances, mainly for the determination of crude fat content. It consists of three parts: an extraction flask, an extraction tube, and a condenser. All connections must be airtight to prevent air leakage. Its working principle is based on solvent reflux and siphon phenomena, and continuous cyclic extraction is used to improve efficiency.

[0003] For example, Chinese patent CN220656477U discloses a Soxhlet extractor with purification function, which includes a condenser, an extraction tube and an extraction bottle. The condenser is installed at the upper end of the extraction tube and the extraction bottle is installed at the lower end of the extraction tube. The extraction tube is provided with a siphon tube and a connecting tube. It also includes an extraction purification core. The extraction purification core is installed in the extraction tube through a bracket. The sample and packing material are placed in the extraction purification core from top to bottom.

[0004] In traditional Soxhlet extractors, the solid material to be extracted is usually carefully placed manually into the filter paper sleeve or the corresponding extraction chamber during the feeding process. Due to the relatively small opening and delicate internal structure of the extractor, it is easy for the material to spill or be unevenly placed. In addition, when adding material to the extractor components at higher positions, operators often need to use climbing tools or props to reach the appropriate operating height, which can easily lead to falls and injuries due to instability. To address the above problems, a feeding auxiliary structure for Soxhlet extractors is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a feeding auxiliary structure for a Soxhlet extractor.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a feeding auxiliary structure for a Soxhlet extractor, comprising a feeding mechanism and a lifting mechanism. The feeding mechanism includes a fixed plate, a controller, a feeding pipe, a storage chamber, a flow regulating valve, and a motor. A spiral conveying rod is rotatably connected inside the feeding pipe. The output end of the motor is fixedly connected to one end of the spiral conveying rod. The top end of the flow regulating valve is fixedly connected to one end of the feeding pipe, and a conveying hose is provided at the bottom end of the flow regulating valve. The bottom of the storage chamber is fixedly connected to the top of the feeding pipe. The bottom of the feeding pipe is fixedly installed to the top of the fixed plate. A scale line is provided on the outside of the storage chamber. The lifting mechanism includes a base and a cylinder. The cylinder is fixedly installed inside the base, and a lifting rod is provided at the top of the cylinder. The top of the lifting rod is fixedly installed to the bottom of the fixed plate. An anti-slip pad is adhered to the bottom of the base.

[0007] Preferably, the top two ends of the fixing plate have two through holes symmetrically opened through, and a protective shell is fixedly connected to the outside of the motor.

[0008] Preferably, the top of the controller is fixedly installed to the bottom of the fixing plate, and two support rods are symmetrically fixedly connected to the top two ends of the base.

[0009] Preferably, the outer side of the support rod is slidably installed with the inner side of the through hole, and a threaded rod is rotatably installed on the outer side of the support rod.

[0010] Preferably, the lifting mechanism further includes two limiting rods, a clamping plate, and a connecting rod, and the outer wall of the threaded rod is threaded with a movable ring.

[0011] Preferably, one end of the limiting rod is fixedly connected to the top of the movable ring, and the other end of the limiting rod is slidably connected to the inner side of the support rod.

[0012] Preferably, one end of the connecting rod is fixedly connected to the outer side of the movable ring, and the other end of the connecting rod is fixedly installed to the outer side of the clamping plate, and a rubber pad is provided on the inner side of the clamping plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the feeding auxiliary mechanism, through the material storage and conveying components, allows the operator to simply add the material to the storage bin. The motor drives the screw conveyor to start rotating, conveying the material in the storage bin into the Soxhlet extractor through the material conveying pipeline composed of the screw conveyor and the feeding pipe. The flow regulating valve controls the material flow according to the set opening degree, so that the material can enter the Soxhlet extractor evenly and stably. By using the screw conveyor and the flow regulating valve, the material can be easily and evenly conveyed into the Soxhlet extractor, avoiding the problems of material spillage and uneven placement that are easy to occur in traditional manual feeding, greatly simplifying the feeding process and saving feeding time.

[0015] 2. In this utility model, by setting up a lifting mechanism, the lifting rod and the feeding mechanism can be moved up and down as a whole by a cylinder according to the height of the Soxhlet extractor and the position of the feeding port, thereby adjusting the connection port of the conveying hose to a suitable height. The lifting mechanism allows the entire feeding auxiliary structure to adapt to a suitable operating height, so that the operator does not need to climb or use objects to raise it, reducing the risk of injury due to instability.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a feeding auxiliary structure for a Soxhlet extractor, including a feeding mechanism 1 and a lifting mechanism 2. The feeding mechanism 1 includes a fixed plate 11, a controller 12, a feeding pipe 14, a storage chamber 15, a flow regulating valve 18, and a motor 110. A spiral conveying rod 111 is rotatably connected inside the feeding pipe 14. The output end of the motor 110 is fixedly connected to one end of the spiral conveying rod 111. The top end of the flow regulating valve 18 is fixedly connected to one end of the feeding pipe 14, and a conveying hose 19 is provided at the bottom end of the flow regulating valve 18. The bottom of the storage chamber 15 is fixedly connected to the top of the feeding pipe 14. The bottom of the feeding pipe 14 is fixedly installed to the top of the fixed plate 11. A scale line 16 is provided on the outside of the storage chamber 15. Two through holes 17 are symmetrically opened through both ends of the top of the fixed plate 11. A protective shell 13 is fixedly connected to the outside of the motor 110. The top of the controller 12 is fixedly installed to the bottom of the fixed plate 11.

[0024] The specific settings and functions of this embodiment are described below: This feeding auxiliary mechanism, through the material storage and conveying components, allows the operator to simply add the material to the storage bin 15, and then easily and evenly convey the material to the Soxhlet extractor using the screw conveyor 111 and the flow regulating valve 18. This avoids problems such as material spillage and uneven placement that are common in traditional manual feeding, greatly simplifies the feeding process and saves feeding time.

[0025] Example 2: Figure 1 , Figure 2 and Figure 4As shown, the lifting mechanism 2 includes a base 21 and a cylinder 211. The cylinder 211 is fixedly installed inside the base 21, and a lifting rod 24 is provided on the top of the cylinder 211. The top of the lifting rod 24 is fixedly installed to the bottom of the fixing plate 11. An anti-slip pad 22 is adhered to the bottom of the base 21. Two support rods 23 are symmetrically fixedly connected to the top two ends of the base 21. The outer side of the support rod 23 is slidably installed to the inner side of the through hole 17. A threaded rod 25 is rotatably installed on the outer side of the support rod 23. The lifting mechanism 2 also includes two limiting rods 27, a clamping plate 29, and a connecting rod 28. A movable ring 26 is threadedly engaged on the outer wall of the threaded rod 25. One end of the limiting rod 27 is fixedly connected to the top of the movable ring 26, and the other end of the limiting rod 27 is slidably connected to the inner side of the support rod 23. One end of the connecting rod 28 is fixedly connected to the outer side of the movable ring 26, and the other end of the connecting rod 28 is fixedly installed to the outer side of the clamping plate 29. A rubber pad 210 is provided on the inner side of the clamping plate 29.

[0026] The overall effect of this embodiment is that the lifting mechanism 2 allows the entire feeding auxiliary structure to adapt to a suitable operating height, eliminating the need for operators to climb or use props, reducing the risk of injury due to instability, and making the feeding process more stable and safe after the Soxhlet extractor is fixed.

[0027] The usage and working principle of this device are as follows: Based on the height of the Soxhlet extractor and the position of the feeding port, the cylinder 211 can drive the lifting rod 24 and the feeding mechanism 1 to move up and down as a whole, thereby adjusting the connection port of the conveying hose 19 to a suitable height. Then, the operator rotates the threaded rod 25. The outer wall of the threaded rod 25 engages with the inner wall of the movable ring 26. Therefore, when the threaded rod 25 is rotated, the movable ring 26 can move along the threaded rod 25, thereby driving the connecting rod 28 and the clamping plate 29 to move closer to the Soxhlet extractor until the two clamping plates 29 firmly clamp the feeding part of the Soxhlet extractor. At the same time, the clamping plate 29 contacts the Soxhlet extractor through the rubber pad 210 on its inner side, which can ensure that the Soxhlet extractor is clamped and its position is stable, without damaging the Soxhlet extractor, making it convenient to use.

[0028] Connect the connection port of the conveying hose 19 to the feeding port of the Soxhlet extractor, open the feeding port at the top of the material storage chamber 15, carefully add the prepared solid material to be extracted into the storage chamber 15, close the feeding port to ensure good sealing and prevent material leakage or external impurities from entering, turn on the power switch of the controller 12, input the relevant parameters on the operation panel of the controller 12 according to the extraction requirements, the microprocessor of the internal control module of the controller 12 will intelligently recommend appropriate feeding parameters such as the rotation speed of the screw conveyor 111 and the opening degree of the flow regulating valve 18 based on the input information, and display them on the display screen for the operator to confirm;

[0029] The operator sets the rotation speed of the screw conveyor 111 and the opening of the flow regulating valve 18, presses the start button, and starts the motor 110. The motor 110 drives the screw conveyor 111 to start rotating and working, conveying the material in the material storage bin 15 into the Soxhlet extractor through the material conveying pipeline composed of the screw conveyor 111 and the feeding pipe 14. The flow regulating valve 18 controls the flow rate of the material according to the set opening, so that the material can enter the Soxhlet extractor evenly and smoothly.

[0030] During the material conveying process, the operator can observe the material conveying speed and the amount of material conveyed in real time through the display screen. The remaining amount of material in the material storage bin 15 can be known in real time through the scale line 16. If any abnormality is found, the corresponding parameters can be adjusted in time through the button on the controller 12 to ensure that the feeding process is accurate and smooth. When the amount of material conveyed reaches the set feeding amount, the operator presses the stop button through the controller 12 to stop the operation of the screw conveyor 111, complete the feeding operation, turn off the power switch, and then release the clamping plate 29, remove the feeding auxiliary structure, and proceed with the subsequent normal extraction operation of the Soxhlet extractor.

[0031] This feeding auxiliary mechanism, through the material storage and conveying components, allows operators to simply add materials to the storage bin 15. The screw conveyor 111 and flow regulating valve 18 then easily and evenly convey the materials into the Soxhlet extractor, avoiding problems such as material spillage and uneven placement that are common with traditional manual feeding. This greatly simplifies the feeding process and saves feeding time. At the same time, the lifting mechanism 2 allows the entire feeding auxiliary structure to adapt to a suitable operating height, eliminating the need for operators to climb or use props, reducing the risk of injury due to instability. Furthermore, once the Soxhlet extractor is secured, the feeding process becomes more stable and safer.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
