Description

Technical Field

[0001] This utility model relates to the technical field of quantitative extraction of indole in production, specifically a quantitative extraction device for indole production. Background Technology

[0002] Indole is a compound formed by the symmetric combination of pyrrole and benzene, also known as benzopyrrole, with the chemical formula C8H7N. Pyrrole and benzene can be mixed in two ways, referred to as indole and isoindole, respectively. Indole and its homologues and derivatives are widely found in nature, primarily in natural flower oils such as jasmine, bitter orange blossom, daffodil, and violet. During production and processing, indole solutions are typically extracted through liquid-to-methanol crystallization in an indole-3-methanol crystallization vessel. The extracted indole solution needs to be collected using a guide tube, and a certain amount of solution needs to be extracted and analyzed during this process. Quantitative extraction requires the use of a quantitative extraction device.

[0003] Existing quantitative extraction devices for indole production and processing lack automatic quantitative control during the extraction process. Operators need to monitor the graduation lines in the internal container of the extraction device and stop extraction when the indole solution level reaches the designated volume mark. This extraction method requires operators to constantly monitor the liquid level in the extraction equipment, making it difficult to control the volume and increasing the workload of the operators. In response, this design proposes a quantitative extraction device for indole production. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative extraction device for indole production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a quantitative extraction device for indole production, comprising an installation tube and a quantitative sampling mechanism and a flow guiding assembly both installed on the top of the installation tube;

[0006] The quantitative sampling mechanism includes a sampling slot inserted into one side of the outer wall of the mounting tube. A connecting frame is inserted into one side of the top of the sampling slot. A sealing plug is fixedly connected to the bottom of the connecting frame through the inner wall of the sampling slot. A drainage slot is provided on one side of the bottom of the inner wall of the sampling slot. A small electric push rod is installed on one side of the top of the sampling slot, and the output end of the small electric push rod is fixedly connected to one end of the connecting frame. A limiting tube is inserted into the other side of the top of the sampling slot. A limiting shaft is inserted into the inner wall of the limiting tube. A float is fixedly provided at the bottom of the limiting shaft. A contact shaft is fixedly provided at the top of the limiting shaft. A mounting frame is fixedly provided on one side of the top of the limiting tube. A contact switch is installed below the top end of the mounting frame.

[0007] In one example, a connecting pipe is inserted into one side of the bottom of the sampling tank, and the inner wall of one end of the connecting pipe is connected to the inner wall of the drainage tank, and the outer wall of the sealing plug fits into the inner wall of the drainage tank.

[0008] In one example, the flow guiding assembly includes a conduit inserted into one side of the outer wall of the sampling slot, with the inner walls at both ends of the conduit communicating with the inner walls at both ends of the sampling slot, respectively.

[0009] In one example, a small water pump is installed in the middle of the conduit, and a drainage tube is inserted through the inner wall of the conduit. The inner wall of one end of the drainage tube passes through the inner wall of one end of the conduit and communicates with the output end of the small water pump.

[0010] In one example, the inner wall of the installation tube is provided with a flow groove, the inner wall of one end of the drainage tube passes through the inner wall of the sampling groove and the inner wall of the installation tube and communicates with the inner wall of the flow groove, and one end of the connecting tube is inserted and connected to a drain hose.

[0011] In one example, both the small water pump and the small electric actuator are electrically connected to an external power source via a contact switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a quantitative extraction mechanism and a flow guiding component, during the indole solution production and processing, the entire installation tube is installed in the middle of the collection device. A portion of the solution is introduced into the sampling tank through the flow guiding component. As the solution accumulates, the liquid level rises, and the float rises accordingly. This causes the limiting shaft and contact shaft to rise in the limiting tube until they contact the contact switch on the mounting frame, which controls the flow guiding component to extract the solution. At the same time, a small electric push rod is activated, pushing the connecting frame to pull the sealing plug out of the drain tank, thus easily discharging the quantitatively collected indole. This eliminates the need for staff to constantly monitor the liquid level of the extracted solution, facilitating volume control, reducing the workload of staff, and improving the convenience of quantitative indole collection.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 The present invention provides a technical solution: a quantitative extraction device for indole production, comprising an installation tube 1 and a quantitative sampling mechanism 2 and a flow guiding component 3, both installed on the top of the installation tube 1;

[0021] The quantitative sampling mechanism 2 includes a sampling groove 201 inserted into one side of the outer wall of the installation tube 1. A connecting frame 202 is inserted into one side of the top of the sampling groove 201. A sealing plug 203 is fixedly connected to the bottom of the connecting frame 202 through the inner wall of the sampling groove 201. A drain groove 204 is opened on one side of the bottom of the inner wall of the sampling groove 201. A small electric push rod 205 is installed on one side of the top of the sampling groove 201, and the output end of the small electric push rod 205 is fixedly connected to one end of the connecting frame 202. A limiting tube 206 is inserted into the other side of the top of the sampling groove 201. A limiting shaft 207 is inserted into the inner wall of the limiting tube 206. A float ball 208 is fixedly installed at the bottom of the limiting shaft 207. A contact shaft 209 is fixedly installed at the top of the limiting shaft 207. A mounting frame 210 is fixedly installed on one side of the top of the limiting tube 206. A contact switch 211 is installed below the top end of the mounting frame 210.

[0022] In use, the installation tube 1 is installed in the middle of the indole solution processing and collection equipment, allowing the indole solution to flow through the flow groove 4 in the inner wall of the installation tube 1 in the collection equipment without affecting the collection of the solution. During the flow of the solution, the small water pump 302 on the flow guiding component 3 is activated to draw out the flowing solution and enter the sampling tank 201 through the flow guiding component 3. The solution continuously accumulates in the sampling tank 201, causing the liquid level to rise. During the rise, the float 208 floats in the solution, carrying the limiting shaft 207 to slide and rise in the limiting tube 206, and then carrying the contact shaft 209 to rise into the solution. When the contact switch 211 at the bottom of the mounting bracket 210 is triggered, the flow guide assembly 3 stops extracting. At the same time, the small electric push rod 205 starts, which pushes the connecting bracket 202 to rise at the top of the sampling tank 201, thereby driving the sealing plug 204 to detach from the drain tank 203. The quantitatively extracted indole solution is then discharged through the connecting tube 212 for collection and detection, achieving the purpose of automatic quantitative extraction control. This eliminates the need for staff to constantly monitor the liquid level of the extracted solution, facilitating quantitative control, reducing the workload of staff, and improving the convenience of the device for quantitative extraction of indole.

[0023] Furthermore, a connecting pipe 212 is inserted and connected to one side of the bottom of the sampling tank 201, and the inner wall of one end of the connecting pipe 212 is connected to the inner wall of the drainage tank 204, and the outer wall of the sealing plug 203 fits into the inner wall of the drainage tank 204. When extracting the indole solution, the connecting frame 202 squeezes the sealing plug 203 into the drainage tank 204 to seal it, so that the indole solution in the sampling tank 201 accumulates continuously and reaches a certain capacity, causing the float 208 to float and rise to a certain height, thereby triggering the contact switch 211.

[0024] Furthermore, the flow guiding assembly 3 includes a conduit 301 inserted into one side of the outer wall of the sampling groove 201, with the inner walls at both ends of the conduit 301 communicating with the inner walls at both ends of the sampling groove 201, while the upper and lower ends of the sampling groove 201 are not connected. The flow groove 4 inside the installation tube 1 is connected through the drainage tube 303 inside the conduit 301 and the inner wall at the top end of the conduit 301. The specific connection method is shown in the attached instruction manual. Figure 2 Instruction manual attached Figure 4 and instruction manual Figure 5 As shown.

[0025] A small water pump 302 is installed in the middle of the conduit 301. A drainage pipe 303 is inserted and connected to the inner wall of the conduit 301. The inner wall of one end of the drainage pipe 303 passes through the inner wall of one end of the conduit 301 and is connected to the output end of the small water pump 302. After the drainage pipe 303 is inserted into the flow channel 4 inside the installation pipe 1, the installation pipe 1 is installed in the middle of the indole solution collection device. Therefore, when the indole solution is collected, the solution flows inside the flow channel 4 and is then extracted by the flow guide component 3, so that the solution is drawn into the drainage pipe 303 and then guided into the inner wall above the sampling tank 201 for collection by the small water pump 302 and the inner wall of the conduit 301.

[0026] Furthermore, a flow groove 4 is provided on the inner wall of the installation tube 1. The inner wall of one end of the drainage tube 303 passes through the inner wall of the sampling groove 201 and the inner wall of the installation tube 1 and communicates with the inner wall of the flow groove 4. One end of the connecting tube 212 is connected to a drain hose 5. After quantitative collection is completed, the sealing plug 203 is opened, and the solution is discharged into the connecting tube 212 through the drain groove 204. Then, the staff can operate the drain hose 5 on the connecting tube 212 to insert it into the detection and collection container for detection. Since the drain hose 5 is a flexible hose, it can be twisted at any angle during collection, which is convenient for the staff to operate.

Each embodiment focuses on its differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions of the method embodiments.
