Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction kettle sampling, in particular to a chemical reaction kettle sampling detection device. Background Art

[0002] Rubber products are widely used in all aspects of today's society and play an irreplaceable role. However, during the use of rubber, it will inevitably be affected by external factors, causing the rubber to lose elasticity, deteriorate in performance, and shorten its service life. This process is called rubber aging. In order to slow down the aging of rubber and increase the service life of rubber products, some rubber antioxidants that can inhibit the aging process need to be added to the rubber during the production process. Rubber antioxidants are generally mixed and prepared in a reactor during production. At this time, a sampling and detection device is generally used to sample and detect the prepared rubber antioxidants.

[0003] The sampling and detection devices in the prior art generally insert sampling tubes into solutions at different heights to take samples, and then use the detector to detect them. However, when sampling and testing solutions at different heights, it is generally necessary to repeatedly insert the sampling tube into the jack on the reactor cover for sampling. Repeated insertion can easily cause the toxic gas in the reactor to diffuse from the jack, which can then be inhaled by the staff and affect their life safety. Some also set multiple storage cavities on the sampling tube for sampling, but during testing, multiple samples are generally tested in sequence. At this time, the last sample tested is prone to solidification, which can easily affect the test and is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0023] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0024] A chemical reactor sampling and detection device comprises a fixing box 1, a sampling box 2 is installed at the bottom of the fixing box 1, and a sampling and detection mechanism is arranged on the fixing box 1 and the sampling box 2.

[0025] The sampling and detection mechanism includes an air pump 6 and a PLC controller installed on the top of the fixed box 1. The output end of the air pump 6 and the side of the sampling box 2 are jointly installed with a fixed tube 7, and the side of the sampling box 2 is provided with a flow hole adapted to the fixed tube 7. A detection component is arranged on the fixed box 1. The side of the sampling box 2 is provided with a plurality of fixed holes, and a solenoid valve 5 is fixed in each of the plurality of fixed holes. The top and bottom of the fixed box 1 are provided with mounting holes, and the side of the sampling box 2 is provided with a moving hole, and a water inlet pipe 8 is jointly installed on the two mounting holes and the moving hole. A diversion component adapted to the water inlet pipe 8 is arranged in the sampling box 2. A water storage chamber 21 is provided on the sampling box 2, and an inverted Z-shaped hole is provided on the sampling box 2. A drain pipe 10 is installed on the inverted Z-shaped hole, and the drain pipe 10 is connected to the water storage chamber 21. The bottom inner wall of the sampling box 2 is provided with a drainage hole connected to the water storage chamber 21, and the fixed box 1 and the sampling box 2 are respectively provided with a blocking component for blocking the water inlet pipe 8 and the drainage hole.

[0026] By means of the above structure, when in use, the rubber antioxidants of different heights can be sucked into the sampling box 2 through the electromagnetic valves 5, air pumps 6 and fixed pipes 7 at different positions, and then contacted with the detection assembly and detected. When the detection is completed, the components in the sampling box 2 can be flushed through the arrangement of the water inlet pipe 8, the drain pipe 10 and the water storage chamber 21. When the flushing is completed, the above operation can be repeated again for detection, and then the rubber antioxidants of different heights can be sampled and tested. There is no need to plug and unplug back and forth, and the gas is prevented from being discharged from the jack. At the same time, automatic sampling detection and cleaning can be realized, which not only reduces the work intensity, but also allows one person to sample and test the rubber antioxidants in multiple reactors at the same time, which is convenient for use.

[0027] The sealing component includes a movable cavity opened on the fixed box 1 and connected with the water inlet pipe 8, a sealing block 14 is slidably arranged on the relative inner wall of the movable cavity, a movable groove connected with the drainage hole is opened on the bottom inner wall of the sampling box 2, a sealing plate 17 is slidably installed in the movable groove, a triangular block 18 is installed on the side inner wall of the sampling box 2, sealing gaskets are installed on the four side outer walls of the sealing block 14 and the sealing plate 17, and a driving unit is arranged on the fixed box 1 to enable the sealing block 14 and the sealing plate 17 to move simultaneously.

[0028] In this solution, by providing the blocking block 14, the blocking plate 17 and the triangular block 18, it is convenient to block the water inlet pipe 8 and the drainage hole.

[0029] Specifically, the movement of the blocking block 14 will block or unblock the water inlet pipe 8, so that the sampling box 2 can be flushed when a height detection is completed. At the same time, the setting of the blocking plate 17 prevents the rubber antioxidant from flowing from the drainage hole to the water storage chamber 21 during sampling and affecting the drainage pipe 10. The setting of the triangular block 18 facilitates the blocking of the mobile groove to prevent the rubber antioxidant from entering the mobile groove.

[0030] The driving unit includes a motor 11 installed on the side of the fixed box 1. A screw rod 12 is rotatably installed on the inner wall of the side of the fixed box 1, and one end of the screw rod 12 is installed on the output shaft of the motor 11. A threaded block 13 is threadedly sleeved on the screw rod 12, and a movable hole adapted to the threaded block 13 is opened on the top inner wall of the fixed box 1, and a blocking block 14 is installed on the side wall of the threaded block 13. A winding roller 15 is fixedly sleeved on the screw rod 12, and a pull rope 16 is wound and installed on the winding roller 15. A first rope hole is opened on the fixed box 1, and a second rope hole connected to the movable groove is opened on the top of the sampling box 2. The other end of the pull rope 16 passes through the first rope hole and the second rope hole in sequence and is installed on the side of the blocking plate 17, and an elastic element is set on the side of the blocking plate 17.

[0031] In this solution, the blocking block 14 and the blocking plate 17 can be easily moved by arranging the motor 11 , the screw rod 12 , the threaded block 13 , the winding roller 15 and the pull rope 16 .

[0032] Specifically, the motor 11 can rotate the screw rod 12 , which will move the blocking block 14 through the threaded block 13 , and at the same time, the screw rod 12 will move the blocking plate 17 through the winding roller 15 and the pull rope 16 .

[0033] The elastic element includes two springs 19 installed on the side of the blocking plate 17, and the other ends of the two springs 19 are installed on the inner wall of the side of the moving groove.

[0034] In this solution, the spring 19 is provided to facilitate the resetting of the blocking plate 17 .

[0035] Specifically, when the pull rope 16 does not pull the blocking plate 17 , the blocking plate 17 will be reset under the action of the spring 19 .

[0036] The detection assembly includes a detector 3 installed on the inner wall of the bottom of the fixed box 1, and a detection head 4 is fixedly arranged at the bottom of the detector 3. Specifically, the detector 3 and the detection head 4 are prior art. When in use, the rubber antioxidant can be detected, and an avoidance hole adapted to the detection head 4 is fixedly arranged at the bottom of the fixed box 1.

[0037] In this solution, the detection instrument 3 and the detection head 4 are arranged to facilitate the detection of the rubber antioxidant.

[0038] The diversion assembly includes a fixed frame 9 installed on the inner wall of the side of the sampling box 2, a diversion cavity is opened on the fixed frame 9, and a plurality of water outlet holes connected to the diversion cavity are respectively opened on the four inner walls of the fixed frame 9. One end of the water inlet pipe 8 is installed on the side of the fixed frame 9, and the water inlet pipe 8 is connected to the diversion cavity.

[0039] In this solution, the diversion cavity and multiple water outlet holes are arranged on the fixed frame 9 to facilitate water diversion.

[0040] Specifically, water flows into the diversion cavity through the water inlet pipe 8, and then flows out through a plurality of water outlets, thereby flushing the detection head 4 from four sides, resulting in a better flushing effect.

[0041] A frame-shaped electromagnet 20 is fixedly disposed on the sampling box 2 .

[0042] In this solution, the frame-shaped electromagnet 20 is provided so that the frame-shaped electromagnet 20 can absorb the reaction kettle during use, thereby preventing the fixed box 1 from moving during detection.

[0043] In summary: when in use, first hold the fixed box 1 and insert the sampling box 2 into the detection hole on the reactor, then make the frame-shaped electromagnet 20 contact the reactor, and then energize it so that the frame-shaped electromagnet 20 absorbs the reactor, thereby preventing the fixed box 1 from moving during detection.

[0044] After being fixed, the water inlet pipe 8 and the drain pipe 10 are first connected to the external water source and the water absorber respectively, and then the penultimate solenoid valve 5 is opened through the PLC controller. When the penultimate solenoid valve 5 is opened, the PLC controller starts the air pump 6, and the air pump 6 will absorb the gas in the sampling box 2 through the fixed pipe 7. At this time, the rubber antioxidant will enter the sampling box 2 through the opened solenoid valve 5 and the fixed hole and continue to rise. When the rubber antioxidant contacts the detection head 4, the detector 3 extracts and detects the rubber antioxidant through the detection head 4. When the detection is completed, the PLC controller first closes the penultimate solenoid valve 5, and then opens the bottom solenoid valve 5. Then the air pump 6 is reversed to inject gas into the sampling box 2, and at this time, the rubber antioxidant inside the sampling box 2 will flow from the bottom solenoid valve 5 and the fixed hole to the outside of the sampling box 2. After a period of gas is injected, the PLC controller closes the solenoid valve 5 and the air pump 6 and starts the motor 11. The output of the motor 11 will cause the screw 12 to rotate, and the rotation of the screw 12 will cause the winding roller 15 to rotate. The rotation of the winding roller 15 will reel the pull rope 16. The force on the pull rope 16 will cause the blocking plate 17 to move. The movement of the blocking plate 17 will cancel the blockage of the drain hole. At the same time, the rotation of the screw 12 will cause the threaded block 13 to move, and the movement of the threaded block 13 will cause the blocking block 14 to move. When the drain hole is unblocked, the side of the blocking block 14 corresponds to the water inlet pipe 8. Then the screw 12 continues to rotate, and the continued rotation of the screw 12 will cause the blocking block 14 and the blocking plate 17 to continue to move. When the blocking block 14 is misaligned with the water inlet pipe 8, the blocking block 14 does not block the water inlet pipe 8. At this time, the water flows through the water inlet pipe 8 to the fixed frame 9, and rinses the detection head 4 and the sampling box 2 through the diversion cavity and the water outlet. Then the flushing water will flow into the water storage chamber 21 through the drainage hole, and the water will be discharged from the sampling box 2 under the action of the water absorber and the drainage pipe 10. When the flushing is completed, the PLC controller causes the motor 11 to output in the reverse direction, and the reverse output of the motor 11 will cause the screw rod 12 to rotate in the reverse direction, and the reverse rotation of the screw rod 12 will reset the blocking block 14. At the same time, the reverse rotation of the screw rod 12 will cancel the winding of the pull rope 16 by the winding roller 15, and the blocking plate 17 will reset under the action of the spring 19. When the blocking block 14 blocks the water inlet pipe 8 again, the drainage hole is not completely blocked. At this time, the air pump 6 injects gas into the sampling box 2, so that the remaining liquid in the sampling box 2 is discharged into the water storage chamber 21. Then the motor 11 is used to make the sealing plate 17 seal the drainage hole. At this time, the solenoid valve 5 is opened upward in sequence and the above operation is repeated, so that the rubber antioxidant at multiple heights can be tested inside without plugging and unplugging back and forth. At the same time, automatic sampling, testing and cleaning can be realized, which not only reduces the work intensity, but also allows one person to sample and test the rubber antioxidant in multiple reactors at the same time, which is easy to use.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
