Description

Technical Field

[0001] This utility model relates to the field of chemical sampling technology, specifically a sampling device for a reaction vessel. Background Technology

[0002] In chemical synthesis processes, it is essential and common to analyze and determine the reaction status of reactants by taking samples during or after the reaction. The sampling process must not disrupt the conditions of the entire reaction system, nor cause harm or damage to the sampling personnel or equipment. More importantly, representative samples must be taken for analysis. If the sample is not representative, the analysis results will be deviated, which will undoubtedly lead to misjudgment of the state of the reactants. This can result in product quality not meeting requirements or even safety accidents.

[0003] The patent application number "CN221464979U" describes "a sampling device for a reaction vessel, including a vessel body, a mixing mechanism inside the vessel body, an inner tube fixedly installed through one side of the bottom of the vessel body, a plurality of through-holes machined on the wall of the inner tube, the plurality of inner holes being arranged longitudinally in a straight line, an outer tube rotatably connected to the top of the vessel body via a sealed bearing, the inner cavity of the outer tube being tightly fitted with the outer wall of the inner tube, and the outer wall of the outer tube being provided with a plurality of spirally arranged outer holes. This utility model relates to the technical field of chemical sampling. When the outer hole and the inner hole are connected, the reactants at this level will flow into the inner tube through the gap where the inner hole and the outer hole overlap, so the reactants can flow into the sampling vessel for collection at the inner tube. Each outer hole on the outer wall of the outer tube can overlap with the corresponding inner hole, so that the reactants at each level can be taken out. This sampling method is simple and convenient, and can also sample reactants at different depths."

[0004] The above-mentioned patented sampling method is simple and convenient, and can also sample reactants at different depths. However, during use, the inner wall of the inner tube cannot be cleaned to maintain internal cleanliness when sampling at different locations and to separate samples from different locations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a sampling device for a reaction vessel, comprising:

[0027] Reactor 1 with a discharge valve 12 at the bottom;

[0028] A sampling mechanism, located inside the reactor 1, is used for sampling within the reactor 1. The sampling mechanism includes a sampling pipe 8 and a leveling pipe 10. The sampling pipe 8 is fixedly connected inside the reactor 1, with a sampling port 9 on one side. The bottom of the sampling pipe 8 is connected to a discharge valve 12. The leveling pipe 10 is rotatably connected inside the reactor 1 and is sleeved on the sampling pipe 8. The leveling pipe 10 has multiple sampling through holes 11.

[0029] The cleaning mechanism is located inside the material receiving pipe 8 and is used for cleaning inside the material receiving pipe 8. The cleaning mechanism includes a lifting component, a limiting component, a scraper 15 and scraper teeth 6. The lifting component is located inside the material receiving pipe 8, the limiting component is located inside the material receiving pipe 8 and is connected to the scraper 15. The scraper 15 is installed on the lifting component, and the scraper teeth 6 are fixedly connected to the scraper 15 and are slidably connected inside the material receiving port 9.

[0030] In this implementation scheme: the model of the discharge valve 12 can be selected from those available on the market as needed, which will not be elaborated here. The sample is discharged through the discharge valve 12. The adjustment tube 10 is fitted on the material taking tube 8. The multiple material taking holes 11 are at different heights on the adjustment tube 10, corresponding to the material taking port 9, to complete the material taking at different positions. The scraper 15 and the scraper teeth 6 cooperate with each other to complete the scraping of the material taking tube 8 and the material taking port 9, and complete the separation between samples at different positions.

[0031] Specifically, the lifting component is a lifting screw 7, which is rotatably connected to the center of the material receiving tube 8, and the scraper 15 is threadedly connected to the lifting screw 7.

[0032] In this embodiment: the lifting screw 7 rotates to control the height of the scraper 15, thus completing the cleaning process.

[0033] Specifically, the limiting component includes multiple limiting strips 14 and multiple limiting grooves 16. The multiple limiting strips 14 are fixedly connected to the material receiving tube 8 at equal intervals, and the multiple limiting grooves 16 are equally spaced on the scraper 15. Each limiting strip 14 is connected to each limiting groove 16.

[0034] In this embodiment, multiple limiting strips 14 and multiple limiting grooves 16 cooperate one by one to complete the position of the scraper 15, so that the scraper 15 can rise and fall without following the rotation of the lifting screw 7.

[0035] Specifically, it also includes a control mechanism, located on the reactor 1, for controlling the adjusting tube 10 and the lifting screw 7. The control mechanism includes:

[0036] The driving component is mounted on reactor 1; and

[0037] The transmission component is located on the adjustment tube 10 and the material picking tube 8, and the transmission component is connected to the drive component.

[0038] In this embodiment, the control mechanism can control both the sampling and cleaning processes.

[0039] Specifically, the driving components include a lifting cylinder 5, a drive motor 4, and a drive gear 3. The lifting cylinder 5 is fixedly connected to one side of the outer surface of the reactor 1 near the top. The drive motor 4 is fixedly connected to the output end of the lifting cylinder 5, and the drive gear 3 is fixedly connected to the output end of the drive motor 4.

[0040] In this embodiment, the models of the lifting cylinder 5 and the drive motor 4 can be selected from those already available on the market as needed, which will not be elaborated on here. The height of the drive motor 4 is adjusted by adjusting the height of the lifting cylinder 5, thereby completing the height adjustment of the drive gear 3 and realizing its use.

[0041] Specifically, the transmission components include a first driven gear 2 and a second driven gear 13. The first driven gear 2 is fixedly connected to the top of the lifting screw 7, and the second driven gear 13 is fixedly connected to the top of the adjusting tube 10.

[0042] In this embodiment, the first driven gear 2 and the second driven gear 13 have the same size and are connected separately to the drive gear 3 to realize transmission at different positions.

[0043] In use, the drive motor 4 controls the drive gear 3 to rotate, transmitting power to the second driven gear 13, causing the adjusting tube 10 to rotate. This allows the material sampling holes 11 at different positions to align with the material sampling port 9, completing the sampling of raw materials in the reactor 1. The samples are then discharged through the discharge valve 12. After sampling, the adjusting tube 10 closes the material sampling port 9, and the lifting cylinder 5 extends, causing the drive gear 3 to mesh with the first driven gear 2. This causes the lifting screw 7 to rotate, raising and lowering the scraper 15 within the material sampling tube 8. This cleans the material sampling tube 8 and the material sampling port 9, separating samples at different positions. After cleaning, the drive motor 4 rotates in the opposite direction, causing the scraper 15 to rise. After rising, the lifting cylinder 5 retracts, aligning the drive gear 3 with the second driven gear 13, completing sampling at other heights.

[0044] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
