Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and in particular to a sampling and detection mechanism for chlorination reactions. Background Technology

[0002] Chlorination is a chemical reaction in which chlorine reacts with other substances to form chlorides. This type of reaction can occur in a variety of compounds, including organic and inorganic compounds. Chlorination reactions usually involve the use of chlorine gas (Cl2) or chlorinating agents (such as ammonium chloride, sodium chloride, etc.).

[0003] During the reaction process, it is necessary to sample and test the reactants. For example, a sampling and testing device for paclobutrazol chlorination reaction disclosed in Chinese patent CN214200806U controls the synchronous movement of the moving rod and the positioning rod through the handle, thereby extending the sampling shell into the reaction vessel for sampling. The positioning rod positions the sampling shell, and the sealing piston seals the inside of the sleeve, reducing heat loss from the reaction vessel during the sampling process. The feed notch and discharge pipe can be used for sampling and discharge respectively. However, during the discharge process, the sealing column needs to be manually rotated to discharge, resulting in low sampling efficiency. Therefore, we propose a sampling and testing mechanism for chlorination reaction. Utility Model Content

[0004] The purpose of this invention is to provide a sampling and detection mechanism for chlorination reactions, which can automatically discharge the sampled reactants to achieve high sampling efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sampling and detection mechanism for chlorination reaction, comprising a reaction vessel body, a sleeve penetrating the lower side wall of the reaction vessel body, two sealing holes opened on the inner wall of the sleeve, a sampling cylinder movably installed in the sleeve, a sampling port opened on the sampling cylinder, a push rod installed on the sampling cylinder to push the sampling cylinder to move, a sealing plug installed on the push rod and cooperating with the sealing holes, and a handle installed on the push rod. The sampling cylinder has a discharge hole I on its upper part, and the sampling cylinder also has a groove communicating with the discharge hole I. A connecting plate is rotatably connected in the groove. The connecting plate has multiple discharge holes II. A discharge control component for controlling the rotation of the connecting plate is installed on the sleeve.

[0006] By adopting the above technical solution, pushing the handle causes the push rod to move the sampling cylinder into the reactor body. The sampling port on the sampling cylinder can introduce the reactants into the sampling cylinder. After sampling is completed, pulling the handle causes the push rod to move the sampling cylinder back into the sleeve. At this time, the sealing plug is just stuck in the sealing hole, reducing the heat loss of the reactor body during the sampling process. When the sampling cylinder returns to the sleeve, the discharge control component controls the connecting plate to rotate, so that the discharge hole two on the connecting plate coincides with the discharge hole one on the sampling cylinder, realizing the automatic discharge of reactants and improving sampling efficiency.

[0007] A further feature of this invention is that the diameter of the sampling tube is equal to the diameter of the sealing hole.

[0008] By adopting the above technical solution, it is convenient for the sampling tube to pass through the sealing hole on the sleeve and enter the interior of the reactor body for sampling.

[0009] A further feature of this invention is that the second discharge hole has the same specifications as the first discharge hole, and the second discharge hole is distributed in a ring at equal intervals.

[0010] By adopting the above technical solution, it is convenient to automatically discharge material when the discharge hole 2 coincides with the discharge hole 1.

[0011] A further feature of this invention is that the discharge control assembly includes a discharge pipe that is slidably connected to the inner wall of the sleeve, a connecting ring that is rotatably connected to the outside of the discharge pipe, and a connecting spring that connects the connecting ring to the sleeve and is sleeved on the outside of the discharge pipe.

[0012] By adopting the above technical solution, after sampling is completed, pulling the handle causes the push rod to drive the sampling cylinder back into the sleeve, and then squeezing the discharge pipe upward so that the top of the discharge pipe abuts against the connecting plate and rotates the connecting plate, so that the discharge hole two on the connecting plate coincides with the discharge hole one on the sampling cylinder, thereby realizing the automatic discharge of the reactants and improving the sampling efficiency.

[0013] A further feature of this invention is that the cross-sectional area of ​​the discharge pipe is greater than the distribution area of ​​the discharge hole II on the connecting plate.

[0014] By adopting the above technical solution, when the discharge port 2 coincides with the discharge port 1, the reactants discharged can fall completely into the discharge pipe and be discharged, reducing the waste of reactants.

[0015] A further feature of this invention is that the connecting plate is provided with an annular groove adapted to the discharge pipe, and the annular groove is located on the outside of the discharge hole two.

[0016] By adopting the above technical solution, the annular groove is designed to facilitate the insertion and cooperation of the top of the discharge pipe, which can stably drive the connecting plate to rotate.

[0017] A further feature of this invention is that the connecting plate is rotatably connected to the groove via a rotating shaft, and the rotating shaft and the connecting plate are rotated clockwise or counterclockwise via a ratchet and pawl.

[0018] By adopting the above technical solution, the occurrence of misrotation of the connecting plate is reduced. When the second discharge hole is misaligned with the first discharge hole, the sampling cylinder can be sealed for sampling. When the second discharge hole coincides with the first discharge hole, the collected reactants can be discharged.

[0019] A further feature of this invention is that a reference assembly is also installed on the sleeve.

[0020] A further feature of this invention is that the reference assembly includes a positioning plate mounted on the sleeve, a positioning rod mounted on the handle and passing through the positioning plate, and a limiting ring mounted outside the positioning rod.

[0021] A further feature of this invention is that when the limiting ring is in contact with the positioning plate, the connecting plate is located directly above the discharge pipe; and when the handle is in contact with the positioning plate, the sampling cylinder moves to the outside of the sleeve.

[0022] By adopting the above technical solution, when the handle moves the push rod to move the sampling cylinder into the reactor body for sampling, the handle is in contact with the positioning plate. After sampling is completed, pulling the handle moves the push rod to move the sampling cylinder back into the sleeve. When the limiting ring is in contact with the positioning plate, the connecting plate is located directly above the discharge pipe. Then, the discharge pipe controls the connecting plate to rotate to achieve discharge. The entire sampling and discharge process only requires observing the position of the handle and the limiting ring. There is no need to move the handle little by little to operate. The sampling process is quick and convenient.

[0023] The beneficial effects of this utility model are:

[0024] 1. Push the handle to move the push rod and the sampling cylinder into the reactor body. The sampling port on the sampling cylinder can introduce the reactants into the sampling cylinder. After sampling, pull the handle to move the push rod and the sampling cylinder back into the sleeve. At this time, the sealing plug is just stuck in the sealing hole, reducing the heat loss of the reactor body during sampling. When the sampling cylinder returns to the sleeve, the discharge control component controls the connecting plate to rotate, so that the discharge hole 2 on the connecting plate coincides with the discharge hole 1 on the sampling cylinder, realizing the automatic discharge of reactants and improving sampling efficiency.

[0025] 2. When the handle moves the push rod to move the sampling cylinder into the reactor body for sampling, the handle is in contact with the positioning plate. After sampling, pull the handle to move the push rod to move the sampling cylinder back into the sleeve. When the limiting ring is in contact with the positioning plate, the connecting plate is directly above the discharge pipe. Then, the discharge pipe controls the connecting plate to rotate to achieve discharge. The entire sampling and discharge process only requires observing the position of the handle and the limiting ring. There is no need to move the handle little by little to operate. The sampling process is quick and convenient. Attached Figure Description

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Please see Figure 1-4This utility model provides a sampling and detection mechanism for chlorination reaction, including a reaction vessel body 1, a sleeve 2 penetrating the lower side wall of the reaction vessel body 1, two sealing holes 3 opened on the inner wall of the sleeve 2, a sampling cylinder 4 movably installed in the sleeve 2, a sampling port 5 opened on the sampling cylinder 4, a push rod 6 installed on the sampling cylinder 4 to push the sampling cylinder 4 to move, a sealing plug 7 installed on the push rod 6 and cooperating with the sealing holes 3, and a handle 8 installed on the push rod 6. The sampling cylinder 4 has a discharge hole 9 on its upper part, and a groove 10 communicating with the discharge hole 9 is also opened on the sampling cylinder 4. A connecting plate 11 is rotatably connected in the groove 10. The connecting plate 11 has multiple discharge holes 12. A discharge control component 13 for controlling the rotation of the connecting plate 11 is installed on the sleeve 2.

[0034] Pushing handle 8 causes push rod 6 to move sampling cylinder 4 into reactor body 1. Sampling port 5 on sampling cylinder 4 can introduce reactants into sampling cylinder 4. After sampling is completed, pull handle 8 to cause push rod 6 to move sampling cylinder 4 back into sleeve 2. At this time, sealing plug 7 is just stuck in sealing hole 3, reducing heat loss from reactor body 1 during sampling. When sampling cylinder 4 returns to sleeve 2, discharge control component 13 controls connecting plate 11 to rotate, so that discharge hole 2 12 on connecting plate 11 coincides with discharge hole 1 9 on sampling cylinder 4, realizing automatic discharge of reactants and improving sampling efficiency.

[0035] The diameter of the sampling tube 4 is equal to the diameter of the sealing hole 3, which facilitates the sampling tube 4 to pass through the sealing hole 3 on the sleeve 2 and enter the reactor body 1 for sampling.

[0036] The discharge hole 2 12 has the same specifications as the discharge hole 1 9. The discharge holes 2 12 are distributed in a ring at equal intervals, which facilitates automatic discharge when the discharge holes 2 12 and the discharge hole 1 9 overlap.

[0037] The discharge control component 13 includes a discharge pipe 131 that is slidably connected to the inner wall of the sleeve 2, a connecting ring 132 that is rotatably connected to the outside of the discharge pipe 131, and a connecting spring 133 that connects the connecting ring 132 and the sleeve 2 and is sleeved on the outside of the discharge pipe 131. After sampling is completed, pulling the handle 8 causes the push rod 6 to drive the sampling cylinder 4 back into the sleeve 2, and then pressing the discharge pipe 131 upward so that the top of the discharge pipe 131 abuts against the connecting plate 11 and rotates the connecting plate 11, so that the discharge hole 2 12 on the connecting plate 11 coincides with the discharge hole 1 9 on the sampling cylinder 4, thereby realizing the automatic discharge of the reactants and improving the sampling efficiency.

[0038] The cross-sectional area of ​​the discharge pipe 131 is larger than the distribution area of ​​the discharge hole 12 on the connecting plate 11. When the discharge hole 12 coincides with the discharge hole 9, the discharged reactants can fall completely into the discharge pipe 131 and be discharged, reducing the waste of reactants.

[0039] The connecting plate 11 is also provided with an annular groove 14 that is adapted to the discharge pipe 131. The annular groove 14 is located outside the discharge hole 12. The setting of the annular groove 14 makes it easy for the top of the discharge pipe 131 to be inserted and cooperate with it, which can stably drive the connecting plate 11 to rotate.

[0040] The connecting plate 11 is rotatably connected to the groove 10 via a rotating shaft. The rotating shaft and the connecting plate 11 are rotated clockwise or counterclockwise via a ratchet and pawl, which reduces the occurrence of accidental rotation of the connecting plate 11. When the discharge hole 2 12 is misaligned with the discharge hole 1 9, the sampling cylinder 2 can be sealed for sampling. When the discharge hole 2 12 coincides with the discharge hole 1 9, the collected reactants can be discharged.

[0041] The sleeve 2 is also equipped with a reference assembly 15, which includes a positioning plate 151 mounted on the sleeve 2, a positioning rod 152 mounted on the handle 8 and passing through the positioning plate 151, and a limiting ring 153 mounted outside the positioning rod 152. When the limiting ring 153 is in contact with the positioning plate 151, the connecting plate 11 is located directly above the discharge pipe 131. When the handle 8 is in contact with the positioning plate 151, the sampling cylinder 4 moves to the outside of the sleeve 2.

[0042] When the handle 8 moves the push rod 6 to move the sampling cylinder 4 into the reactor body 1 for sampling, the handle 8 is in contact with the positioning plate 151. After sampling is completed, the handle 8 is pulled to move the push rod 6 to move the sampling cylinder 4 back into the sleeve 2. When the limiting ring 153 is in contact with the positioning plate 151, the connecting plate 11 is located directly above the discharge pipe 131. Then, the discharge pipe 131 controls the connecting plate 11 to rotate to achieve discharge. The entire sampling and discharge process only requires observing the position of the handle 8 and the limiting ring 153. There is no need to move the handle 8 little by little to operate. The sampling process is quick and convenient.
