Description

Technical Field

[0001] The invention relates to a pipeline type detector for jasmone production, belonging to the technical field of jasmone sorting and detection. Background Art

[0002] During the jasmone production process, the jasmone produced needs to be detected (separated). During the jasmone production process, jasmone is mixed with several other liquids, and the color of jasmone and these liquids is not significantly different. Existing technologies generally use the following three methods to detect jasmone: First, visually observing the color of the liquid through a sight glass to determine whether it is jasmone or another liquid, and then collecting the liquid separately. This method is difficult to quickly and accurately identify jasmone through visual observation, which can easily lead to raw material loss or incomplete separation, thus affecting product quality and yield. Second, metal electrodes are used to contact the liquid and measure its electrical conductivity to separate jasmone. This device requires a metal sensor to directly contact the liquid, but the mixed liquid in jasmone production is highly corrosive to metal, making the sensor easily damaged. Third, ultrasonic detection is used. Teflon is generally used to improve contact with the mixed liquid, but Teflon is also not suitable for the mixed liquid.

[0003] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0004] The present invention addresses the deficiencies in the background technology and provides a pipeline detector for jasmone production, which can avoid direct contact between metal and the measured liquid, realize automatic detection and discharge, and has high sensitivity, easy installation and low cost.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A pipeline detector for jasmone production includes a reactor, a main discharge pipe is vertically provided at the bottom of the reactor, a first detection pipe is installed at the lower end of the main discharge pipe, a second detection pipe is installed at the lower end of the first detection pipe, and a first branch discharge pipe is installed at the lower end of the second detection pipe; Insulation pads are provided between the main discharge pipe and the first detection pipe, between the first detection pipe and the second detection pipe, and between the second detection pipe and the first branch discharge pipe; The first detection tube and the second detection tube are respectively connected with binding posts, the two binding posts are connected to the control circuit board through wires, and the control circuit board is connected to the PLC display screen through a signal line.

[0006] Furthermore, the main discharge pipe and the first detection pipe, the first detection pipe and the second detection pipe, and the second detection pipe and the first branch discharge pipe are connected via flanges, and the flanges are fixedly connected via insulating bolts.

[0007] Furthermore, the two terminals are respectively welded to the flanges of the first detection tube and the second detection tube.

[0008] Furthermore, a second branch discharge pipe is provided on the first branch discharge pipe, the lower end of the first branch discharge pipe is connected to the impurity container, a first solenoid valve is provided on the first branch discharge pipe, and a second solenoid valve is provided on the second branch discharge pipe, and the first solenoid valve and the second solenoid valve are connected to the PLC display screen through a wire.

[0009] Furthermore, a main valve is provided on the main discharge pipe.

[0013] After adopting the above technical solution, the present invention has the following advantages compared with the prior art: The liquid material flows from the reactor to the main discharge pipe and flows through the first detection tube and the second detection tube in sequence. The first detection tube and the second detection tube are combined into a capacitor. The conversion circuit converts the detected inductance and capacitance signals into different phase-frequency signals and transmits them to the PLC display through the signal line. The PLC display can accurately determine whether the liquid in the tube is jasmone or other impurities based on the different signals received, thereby automatically detecting jasmone.

[0014] When the PLC display screen detects that the liquid in the pipeline is jasmone, the PLC display screen controls the second solenoid valve to open, so that the jasmone is discharged and collected from the second branch discharge pipe. When the PLC display screen detects that the liquid in the pipeline is other impurities, the PLC display screen controls the first solenoid valve to open, so that the impurity liquid flows from the first branch discharge pipe to the impurity container for collection, so that the jasmone can be automatically discharged after being identified, fully realizing automatic detection and discharge.

DETAILED DESCRIPTION

[0019] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0020] like Figure 1-2 As shown, the present invention provides a pipeline detector for jasmone production, including a reactor 16, a main discharge pipe 1 is vertically provided at the bottom of the reactor 16, a first detection tube 3 is installed at the lower end of the main discharge pipe 1, a second detection tube 4 is installed at the lower end of the first detection tube 3, and a first branch discharge pipe 5 is installed at the lower end of the second detection tube 4.

[0021] Insulation pads 8 are provided between the main discharge pipe 1 and the first detection pipe 3 , between the first detection pipe 3 and the second detection pipe 4 , and between the second detection pipe 4 and the first branch discharge pipe 5 .

[0022] The first detection tube 3 and the second detection tube 4 are connected to binding posts 9 respectively. The two binding posts 9 are connected to a control circuit board 14 through wires. The control circuit board 14 is connected to a PLC display screen 15 through a signal line.

[0023] The liquid material flows from the reactor 16 to the main discharge pipe 1 and then sequentially through the first and second detection tubes 3 and 4. The first and second detection tubes 3 and 4 are insulated by an insulating pad 8, forming a capacitor. When different liquid materials (jasmone or other impurities) flow through the first and second detection tubes 3 and 4, their inductance and capacitance characteristics vary significantly. The control circuit board 14 integrates a conversion circuit that converts the detected inductance and capacitance signals into signals with different phases and frequencies, which are then transmitted via signal lines to the PLC display 15. Based on the different signals received, the PLC display 15 accurately determines whether the liquid in the tubes is jasmone or other impurities. This enables automatic detection of jasmone without direct contact with the liquid material and enables appropriate further control. This revolutionizes the process of visually identifying jasmone.

[0024] The main discharge pipe 1 and first detection pipe 3, the first detection pipe 3 and second detection pipe 4, and the second detection pipe 4 and first branch discharge pipe 5 are connected via flanges, which are secured by insulating bolts 7. The first and second detection pipes 3 and 4 are insulated from the pipes at their upper and lower ends, preventing interference from adjacent pipes and allowing them to form independent electrodes. During installation, the first and second detection pipes 3 and 4 are simply connected in series to the discharge pipe. This simple structure requires no major modifications and can be achieved by fully utilizing the existing infusion pipes with minimal modifications.

[0025] The two terminal posts 9 are respectively welded to the flanges of the first detection tube 3 and the second detection tube 4 .

[0026] A second branch discharge pipe 10 is provided on the first branch discharge pipe 5. The lower end of the first branch discharge pipe 5 is connected to an impurity container 13. A first solenoid valve 11 is provided on the first branch discharge pipe 5, and a second solenoid valve 12 is provided on the second branch discharge pipe 10. The first solenoid valve 11 and the second solenoid valve 12 are connected to a PLC display screen 15 via wires. When the PLC display screen 15 detects that the liquid in the pipe is jasmone, the PLC display screen 15 controls the second solenoid valve 12 to open, allowing the jasmone to be discharged and collected from the second branch discharge pipe 10. When the PLC display screen 15 detects that the liquid in the pipe is other impurities, the PLC display screen 15 controls the first solenoid valve 11 to open, allowing the impurity liquid to flow from the first branch discharge pipe 5 to the impurity container 13 for collection. As a result, the jasmone can be automatically discharged after being identified, fully realizing automated detection and discharge.

[0027] A main valve 2 is provided on the main discharge pipe 1 .

[0028] A feed pipe 17 is vertically disposed within the reactor 16. The lower end of the feed pipe 17 extends to a position slightly below the center of the reactor 16. The bottom of the feed pipe 17 is sealed, and a plurality of discharge holes 18 are formed around the bottom of the feed pipe 17. Liquid material discharged from the feed pipe 17 is discharged horizontally through the discharge holes 18, thereby reducing disturbance of the material between the upper and lower layers within the reactor 16.

[0029] Reactor 16 is separated by an upper baffle 19 and a lower baffle 20. Upper baffle 19 is located above discharge hole 18 of feed pipe 17, while lower baffle 20 is located below discharge hole 18 of feed pipe 17. Both baffles 19 and 20 are provided with multiple leakage holes. These baffles block the liquid material entering reactor 16, reducing turbulence and allowing jasmone and liquid impurities to separate into separate layers.

[0030] A liquid level gauge 21 is fixedly provided on the outer wall of the reactor 16 , and the bottom of the liquid level gauge 21 is connected to the bottom of the reactor 16 .

[0031] The main discharge pipe 1, the first detection pipe 3, the second detection pipe 4, the first branch discharge pipe 5, and the second branch discharge pipe 10 are all fitted with a polytetrafluoroethylene (PTFE) tube 6. The PTFE tube 6 is used to prevent liquid material from corroding the inner walls of the pipes. Furthermore, fitting the PTFE tube 6 within the first detection pipe 3 and the second detection pipe 4 allows for stable detection of inductance and capacitance characteristic values.

Any portion not described in detail herein is common knowledge within the skill of one of ordinary skill in the art. The scope of protection of the present invention is determined by the claims. Any equivalent transformation based on the technical teachings of the present invention is also within the scope of protection of the present invention.
