DETAILED DESCRIPTION
[0020] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a high performance liquid chromatograph for triallyl isocyanurate, comprising a body 1 and a degassing monitoring component 6, a degassing chamber 2 is provided on the upper part of the body 1, and a placement groove 3 is provided on the top of the body 1, an arc-shaped slide groove 4 is provided around the placement groove 3, and a limited position channel 5 is provided at the bottom of the arc-shaped slide groove 4, the degassing monitoring component 6 is slidably connected to the inside of the arc-shaped slide groove 4, and the degassing monitoring component 6 comprises a slider 601, a transmission slide rod 602, a gas sleeve 603, a telescopic bellows 604, an elastic bellows 605, an exhaust pipe 606, an air delivery pipe 607, a vacuum pump 608 and an air inlet 609, the bottom of the slider 601 is connected to the transmission slide rod 602, and the outer wall of the transmission slide rod 602 is sleeved with a gas sleeve 603, one side of the gas sleeve 603 is connected to the telescopic bellows 604, and the other side of the gas sleeve 603 is connected to the elastic Bellows 605, the end of the elastic bellows 605 passes through the end of the limiting channel 5 and is connected to the exhaust pipe 606, the end of the telescopic bellows 604 passes through the end of the limiting channel 5 and is connected to the gas supply pipe 607, and the end of the gas supply pipe 607 is connected to the vacuum pump 608, the front of the vacuum pump 608 is provided with an air inlet 609, the side of the degassing chamber 2 away from the vacuum pump 608 is provided with a chromatographic column injection pump 7, the surface of the slider 601 is provided with a monitoring camera 14, the gas sleeve 603, the telescopic bellows 604, and the elastic bellows 605 are located inside the limiting channel 5, and the two sides of the gas sleeve 603 are connected to the telescopic bellows 604 and the elastic bellows 605 through electronic valves, the air inlet 609 is connected to the degassing bottle through a pipeline and a multi-way valve, and the degassing bottle is placed inside the placement groove 3, and the arc-shaped slide groove 4 is surrounded by the outside of the placement groove 3; The specific operation is as follows: a degassing bottle carrying a mobile phase is placed inside the placement tank 3. At this time, the surface of the vibration plate 8 carries the degassing bottle, and the top of the degassing bottle is connected to the air inlet 609 of the vacuum pump 608 and the inlet of the chromatographic column injection pump 7 through pipelines and multi-way valves. When degassing and defoaming, the multi-way valve opens the pipeline leading to the air inlet 609 and closes the pipeline leading to the chromatographic column injection pump 7; At this time, the vacuum pump 608 operates to extract the air inside the degassing bottle for defoaming. The vacuum pump 608 steadily and slowly extracts air from the air pipe 607 and injects it into the telescopic bellows 604. The telescopic bellows 604 expands and stretches along the limiting channel 5 to push the air sleeve 603 so that the transmission slide bar 602 carries the slider 601 to slide in an arc along the arc-shaped slide groove 4. At this time, the electronic valve at the end of the telescopic bellows 604 is closed, so that the monitoring camera 14 moves from one end of the arc-shaped slide groove 4 to the other end. When reaching the end of the arc-shaped slide groove 4, the monitoring camera 14 monitors the bubble situation inside the degassing bottle. If the exhaust force of the vacuum pump 608 is not enough to push the monitoring camera 14 to move, an air pump can be added in the middle of the air pipe 607 to inject external air into it to ensure that the monitoring camera 14 can move. When the telescopic bellows 604 expands and stretches, the air sleeve 603 pushes the elastic bellows 605 to shrink along the inside of the limiting channel 5. A spring that matches the shape of the inside of the limiting channel 5 is arranged inside the elastic bellows 605. When the monitoring camera 14 needs to be reset, the electronic valve at the end of the telescopic bellows 604 opens, so that the air inside passes through the air sleeve 603 and the elastic bellows 605 and is discharged from the outer end of the exhaust pipe 606. At this time, the elastic bellows 605 stretches and the telescopic bellows 604 shrinks, so that the monitoring camera 14 slides back and resets. Based on the above description, when the present invention utilizes the vacuum pump 608 to extract the air inside the degassing bottle to eliminate bubbles, the gas to be discharged is filled into the telescopic bellows 604 to stretch it to push the monitoring camera 14 to slide in an arc along the arc-shaped slide groove 4, so as to monitor the bubble elimination situation inside the degassing bottle at different positions during the degassing process, thereby eliminating the need for manual visual observation to reduce the workload, and using a high-definition camera to capture the bubble situation to make the monitoring result more accurate.
[0022] like Figure 1-Figure 5 As shown, a vibration plate 8 is placed inside the placement groove 3, and a movable lifting rod 9 is connected to the bottom of the vibration plate 8, and a movable ball 10 is arranged at the bottom of the movable lifting rod 9, and the movable lifting rod 9 passes through the bottom of the placement groove 3, and a movable rotating shaft 15 is fixed to the top of the inner wall of the degassing chamber 2, and a convex turntable 11 is connected to the bottom of the movable ball 10, and the top surface of the convex turntable 11 is in contact with the bottom surface of the movable ball 10, and the central axis of the convex turntable 11 coincides with the central axis of the arc-shaped slide groove 4, and a transmission gear ring 12 is fixed to the outer wall of the convex turntable 11, and the outer side surface of the transmission gear ring 12 is meshed and connected with an adapting rack 13, and the top surface of the adapting rack 13 is connected to the bottom surface of the transmission slide rod 602, and the adapting rack 13 and the transmission gear ring 12 are located at the bottom of the limiting channel 5, and the adapting rack 13 and the transmission gear ring 12 are arranged in parallel above the vacuum pump 608 and the chromatographic column injection pump 7; The specific operation is as follows: when the transmission slide bar 602 slides in an arc shape inside the arc-shaped slide groove 4, it will carry the matching rack 13 at its bottom to move synchronously. During the arc-shaped movement of the matching rack 13, the transmission gear ring 12 meshing with it will be driven to rotate. The rotation of the transmission gear ring 12 will drive the convex turntable 11 to rotate. During the rotation of the convex turntable 11, the convex parts on its surface continuously lift the movable lifting rod 9, so that the vibration plate 8 carrying the degassing bottle will vibrate inside the placement groove 3, thereby helping the bubbles to be released faster, so as to speed up the degassing step. The monitoring camera 14 stops naturally when it moves to the two ends of the arc-shaped slide groove 4. Move, at this time, the convex turntable 11 also stops rotating so that the degassing bottle is no longer vibrated, that is to say, the monitoring camera 14 can monitor the bubble situation inside the degassing bottle in a stable state when it reaches the end of the arc-shaped slide groove 4, and a movable ball 10 is provided at the bottom of the movable lifting rod 9. When the convex turntable 11 rotates and the movable lifting rod 9 is raised, the surface of the convex turntable 11 and the movable ball 10 at the bottom of the movable lifting rod 9 rub against each other. The movable ball 10 can convert the sliding friction force into rolling friction force to reduce the friction resistance, and at the same time prevent the bottom of the movable lifting rod 9 or the surface of the convex turntable 11 from wearing.
[0023] like Figure 1-Figure 5 As shown, a method for detecting triallyl isocyanurate using a high performance liquid chromatograph is applied with the above-mentioned high performance liquid chromatograph for triallyl isocyanurate, and the method for detecting triallyl isocyanurate using a high performance liquid chromatograph comprises the following operating steps: Step 1: Place the degassing bottle containing the mobile phase into the placement tank 3. At this time, the surface of the vibration plate 8 carries the degassing bottle, and the top of the degassing bottle is connected to the air inlet 609 of the vacuum pump 608 and the inlet of the chromatographic column injection pump 7 through pipelines and multi-way valves; Step 2: Power on and start the vacuum pump 608 to slowly extract the air inside the degassing bottle, so that the mobile phase can be defoamed. The gas extracted by the vacuum pump 608 enters the telescopic bellows 604 from its exhaust end along the gas pipe 607. At this time, the solenoid valve at the end of the telescopic bellows 604 is closed, so that the telescopic bellows 604 is stretched along the inside of the limit channel 5, thereby pushing the transmission slide bar 602 to drive the slider 601 to carry the monitoring camera 14 to slide along the arc-shaped slide groove 4. The monitoring camera 14 slides along the arc track to detect the bubble situation inside each degassing bottle. When the monitoring camera 14 moves to the end of the arc-shaped slide groove 4, the elastic bellows 605 is compressed to the limit. At this time, the electromagnetic valve at the end of the telescopic bellows 604 and the electromagnetic valve at the end of the elastic bellows 605 are both opened, so that the gas inside the telescopic bellows 604 passes through the gas sleeve 603 and the elastic bellows 605 and is discharged outward along the exhaust pipe 606. At this time, the elastic bellows 605 elastically stretches and resets while the telescopic bellows 604 contracts, so that the monitoring camera 14 can retreat. The cycle is repeated to observe the bubble situation in real time during the degassing of the mobile phase inside the degassing bottle. Step three: When the transmission slide bar 602 slides in an arc shape inside the arc-shaped slide groove 4, it will carry the matching rack 13 at its bottom to move synchronously. During the arc-shaped movement of the matching rack 13, it drives the transmission gear ring 12 engaged with it to rotate. The rotation of the transmission gear ring 12 drives the convex turntable 11 to rotate. During the rotation of the convex turntable 11, the raised parts on its surface continuously lift the movable lifting rod 9, causing the vibration plate 8 to carry the degassing bottle to vibrate inside the placement groove 3, thereby helping the bubbles to be released faster.
