Description

Technical Field

[0001] This utility model relates to the field of peroxide sampling and collection technology, and in particular to a sampling and collection device for the preparation of di-tert-butyl peroxide. Background Technology

[0002] Di-tert-butyl peroxide is an important organic peroxide widely used in polymer synthesis, rubber vulcanization, and other fields. During its preparation, accurate and safe sampling and collection of the reaction solution are crucial for monitoring the reaction process and ensuring product quality.

[0003] A search revealed Chinese patent publication number CN222505908U, which discloses an automatic sampling device for peroxide production inspection. The device includes a mounting column with multiple sampling cylinders mounted along its length on the outer wall. A connecting pipe is fixedly connected to the bottom of one side of each sampling cylinder. A piston block is slidably connected inside the sampling cylinder, and a movable rod is fixedly connected to the top of one side of the piston block, slidably connected to the sampling cylinder. A movable groove is formed on one side of the outer wall of the mounting column, and a moving column, cooperating with the movable rod, drives the piston block within the groove. This patent has the following shortcomings: After sampling, most devices use specialized cleaning agents to directly spray water for cleaning, resulting in poor cleaning effectiveness and an inability to remove stubborn particles. This leads to peroxide residue on the sampling cylinder, which can easily cause decomposition or explosion. Furthermore, it may react with metallic impurities on the device surface to generate more unstable intermediate products or release toxic gases, further exacerbating safety hazards.

Therefore, they should not be construed as limitations on this utility model.

[0026] Reference Figures 1-7 A sampling and collection device for the preparation of di-tert-butyl peroxide includes a sampling platform 2 with a sampling tube 1, a collection bucket 3 on the sampling platform 2, and a mixing bucket 4 at the bottom of the sampling platform 2. It also includes a drive gear 5 rotatably connected to the sampling platform 2, a through hole 6 on the sampling platform 2, and a driven gear 7 rotatably connected to the through hole 6, meshing with the drive gear 5. Brushes 8 are fixedly connected to the inner wall of the driven gear 7. By rotating the drive gear 5 and meshing with the driven gear 7, the driven gear 7 can rotate continuously, causing multiple brushes 8 on the inner wall to rotate simultaneously to clean residues on the outer wall of the sampling tube 1. This prevents cross-contamination between different batches of samples, ensures the accuracy and reliability of each sampling, protects the sampling tube 1, reduces chemical corrosion of the sampling tube 1, and extends its service life.

[0027] An L-shaped plate 9 is fixedly connected to the top of the sampling stage 2. A servo motor 10 is fixedly installed on the top of the L-shaped plate 9. A screw 11 is rotatably connected to the sampling stage 2. One end of the screw 11 is fixedly connected to the output end of the servo motor 10.

[0028] The drive gear 5 is fixedly connected to the bottom end of the screw 11. A movable plate 12 is threadedly connected to the screw 11. A guide rod 13 is fixedly connected to the sampling stage 2. The movable plate 12 is slidably connected to the guide rod 13.

[0029] A sampling pump 14 is fixedly installed on the moving plate 12, and a sampling tube 1 is fixedly installed on the sampling pump 14. A collection tube 15 is fixedly installed on the other end of the sampling pump 14. By starting the servo motor 10, the screw 11 is driven to rotate. Under the guidance of the guide rod 13, the moving plate 12 slides downward steadily on the screw 11, thereby driving the sampling pump 14 on the moving plate 12 to move downward steadily, so that the sampling tube 1 moves downward steadily and enters the mixing tank 4 for sampling. Then, by starting the sampling pump 14, the sample can be drawn through the sampling tube 1 and collected in the collection tank 3 through the collection tube 15, thus completing the sampling and collection.

[0030] A mounting plate 16 is fixedly connected to the bottom of the sampling stage 2. A sealing cylinder 17 is fixedly connected to the mounting plate 16. A piston 18 is slidably connected inside the sealing cylinder 17. The sealing cylinder 17 is divided into a first chamber 19 and a second chamber 20 by the piston 18. A push rod 29 is fixedly connected to the piston 18. A triangular plate 30 is fixedly connected to the top of the push rod 29. A spring 31 is sleeved on the push rod 29.

[0031] Both ends of the spring 31 are fixedly connected to the sealing cylinder 17 of the triangular plate 30. The sampling stage 2 is provided with a sliding hole that matches the triangular plate 30. A drive plate 32 corresponding to the triangular plate 30 is fixedly connected to one side of the bottom of the screw 11. When the screw 11 rotates, it will drive the drive plate 32 to rotate. When the drive plate 32 rotates to the position of the triangular plate 30, it will automatically abut against the inclined surface of the triangular plate 30. Under the guidance of the push rod 29, the triangular plate 30 will drive the push rod 29 to slide downward at the same time, thereby pushing the piston 18 to move. The piston 18 will move downward into the first chamber 19. Then, when the drive plate 32 disengages from the triangular plate 30, the triangular plate 30 will automatically return to its original position under the action of the spring 31. It should be noted that the screw 11 can also drive the drive plate 32 to rotate in the opposite direction and abut against the inclined surface of the triangular plate 30. Regardless of whether the screw 11 rotates forward or backward, the triangular plate 30 can slide up and down.

[0032] Multiple spray pipes 21 are fixedly connected to the outer periphery of the through hole 6. The bottom of the multiple spray pipes 21 is fixedly connected to a liquid collection ring 22. The liquid collection ring 22 is fixedly connected to the first chamber 19 by an inlet pipe 23. The first chamber 19 is fixedly connected to a suction pipe 24, which is connected to the cleaning agent for the external sampling tube 1. When the triangular plate 30 is reset upward, it drives the push rod 29 and the piston 18 to move upward to the second chamber 20. At the same time, a negative pressure chamber is formed in the first chamber 19, and the cleaning agent is drawn into the first chamber 19 through the suction pipe 24. Then, when the drive plate 32 touches the inclined surface of the triangular plate 30 again, the piston 18 moves downward again to squeeze the cleaning agent in the first chamber 19 from the inlet pipe 23 into the liquid collection ring 22, and then into the multiple spray pipes 21. The multiple spray pipes 21 spray the cleaning agent at the position of the brush 8 at the same time, thereby assisting the cleaning effect of the sampling tube 1.

[0033] Multiple jet pipes 25 are fixedly connected to the outer circumference of the through hole 6. The bottom of the multiple jet pipes 25 is fixedly connected to a gas collecting ring 26. An air inlet pipe 27 is fixedly connected between the second chamber 20 and the gas collecting ring 26. An air suction pipe 28 is fixedly connected to the second chamber 20. When the piston 18 pushes the cleaning agent in the first chamber 19 downward, a negative pressure chamber is automatically formed in the second chamber 20. Gas is drawn into the second chamber 20 through the air suction pipe 28 and stored therein. Then, when the piston 18 returns to its original position, the gas is automatically sprayed into the air inlet pipe 27, enters the gas collecting ring 26, and is then sprayed from the multiple jet pipes 25 to the brush 8 to assist in the removal of stubborn particles on the sampling tube 1, making the cleaning effect of the sampling tube 1 better and helping to make the test results after the next sampling more accurate. It should be noted that one-way valves are installed in the liquid inlet pipe 23 and the liquid suction pipe 24, as well as the air inlet pipe 27 and the air suction pipe 28.

[0034] In this invention, during use, the suction tube 24 is first disconnected from the special cleaning agent used for cleaning the external sampling tube 1. Then, the reaction mixture container 4 to be sampled and collected is placed on the sampling platform 2. The servo motor 10 is started to drive the screw 11 to rotate. At the same time, the drive gear 5 drives the driven gear 7 to rotate, causing the brush 8 to rotate. Before sampling, the dust and impurities on the outer wall of the sampling tube 1 are brushed off. The cleaning effect is better with the help of the air jet pipe 25. The moving plate 12 drives the sampling pump 14 and the sampling tube 1 to move downwards simultaneously, moving to the shallow part of the mixture container 4. When the sample is set, the sampling pump 14 is started to draw the reaction liquid into the collection tube 15 and into the collection bucket 3 for collection. When it is necessary to sample the deep part of the mixture bucket 4, the sampling tube 1 is controlled to move downward again to draw the reaction liquid from the deep part and collect it into another new collection bucket 3. After the sampling is completed, the suction tube 24 is connected to the special cleaning agent for cleaning the external sampling tube 1. The servo motor 10 is started to control the screw 11 to rotate in the opposite direction, so that the sampling tube 1 is cleaned by the brush 8, the cleaning agent and the airflow of the jet pipe 25 during the upward process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
