DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In order to solve the technical problem of how to avoid liquid leakage after the probe is disassembled, the utility model provides an instrument probe installation structure of a cooling crystallization system, which can prevent liquid leakage after the probe is disassembled.

[0027] It should be noted that the instrument probe mounting structure of the cooling crystallization system described in the present invention is used for but not limited to temperature measuring probes, etc. For the sake of convenience, in the present invention, only the application of the instrument probe mounting structure of the cooling crystallization system to the temperature measuring probe is used as an example for explanation. The principle of applying the instrument probe mounting structure of the cooling crystallization system to other types of detection probes is essentially the same as the principle applied to the temperature measuring probe, and will not be elaborated here.

[0028] See also Figure 1-4, this embodiment provides an instrument probe installation structure for a cooling crystallization system, including a docking part 1 and a detection probe 2, the docking part 1 is welded to the outer wall of the reactor body 3, the docking part 1 includes a shell 11, an opening and closing mechanism 12, a sealing cylinder 13 and a mounting cylinder 14, the detection probe 2 is a temperature measuring probe, wherein the shell 11 is square, and an opening 101 is provided on one side of the shell 11, and one side of the opening 101 of the shell 11 is welded to the outer wall of the reactor, and the welding position is the original mounting hole position of the temperature measuring probe, and a through hole 102 is provided on the other side of the shell 11, and the through hole 102 is used for the penetration of the detection probe 2, which can penetrate the through hole 102, the shell 11 and the opening 101, and be inserted into the interior of the reactor body from the original hole position on the outer wall of the reactor body 3; the opening and closing mechanism 12 is provided on the shell 11, and is used to open or close Opening 101. When the detection probe 2 is disassembled, the tail end of the detection probe 2 is moved into the shell 11, and then the opening 101 is closed, blocking the connection between the original opening on the kettle body and the inner chamber of the shell 11, thereby preventing the liquid inside the kettle body from leaking when the probe is completely pulled out from the docking part 1; in addition, the sealing cylinder 13 is arranged on one side of the through hole 102 of the shell 11, and the mounting cylinder 14 is arranged at the end of the sealing cylinder 13 away from the shell 11, which is used for sealing when the tail end of the probe has not yet moved into the shell 11 during the disassembly and extraction process, thereby avoiding leakage from the through hole 102; a threaded portion 201 is provided on the detection probe 2, and the detection probe 2 is plugged into the sealing cylinder 13 and passes through the through hole 102 and the opening 101 of the shell 11, and the threaded portion 201 is threadedly connected to the mounting cylinder 14.

[0029] In this embodiment, the disassembly steps are first to rotate the detection probe 2, undo the threaded connection between the threaded part 201 and the mounting tube 14, and then pull the detection probe 2 outward. When the detection probe 2 is pulled out until the tail end is located inside the shell 11, the opening 101 is closed by the opening and closing mechanism 12, and then the detection probe 2 is continued to be pulled out until it is completely separated from the docking part 1. In the middle of the pulling process, the sealing tube 13 is used to seal and prevent leakage. In the final stage of the pulling process, the opening 101 is closed to seal and prevent leakage.

[0030] It can be understood that the reactor body 3 is only a reaction vessel commonly used in the cooling crystallization system. It is only used as an example here and does not limit the reaction vessel for cooling crystallization. If the docking part 1 is set as an overall inclined upward setting, its leak-proof effect is better.

[0031] In one embodiment, see Figure 2 and Figure 3When the sealing plate 121 is lifted up until the limiting edge 122 abuts against the inner top wall of the shell 11, the two magnets 104 generate magnetic attraction, positioning the sealing plate 121 at this position, and opening the opening 101.

[0032] Furthermore, in order to facilitate lifting and pressing the sealing plate 121, a lifting edge 105 is provided on the top of the sealing plate 121 for manual lifting and pressing; a groove is provided on the inner side of the shell 11 for inserting the sealing plate 121 after pressing it down to seal the opening 101.

[0033] Furthermore, in order to facilitate the observation of whether the tail end of the detection probe 2 moves to the inside of the shell 11, a transparent glass 106 is provided on the shell 11. The transparent glass 106 is provided on both sides of the shell 11. The angle of the transparent glass 106 can be used to view the detection probe 2 inside it, and to determine whether the tail end of the detection probe 2 moves to the inside of the shell 11 and passes under the sealing plate 121.

[0034] In one embodiment, see Figure 2 and Figure 3 In order to provide sealing and leakage prevention during the movement of the detection probe 2, the sealing cylinder 13 includes an outer cylinder 131 and a sealing layer 132. The outer cylinder 131 is connected to the shell 11, and the sealing layer 132 is arranged on the inner side of the outer cylinder 131. The sealing layer 132 fills the gap between the outer side of the detection rod body of the detection probe 2 and the outer cylinder 131 to form a sealing effect.

[0035] Furthermore, in order to press tightly on the side close to the shell 11 and facilitate the insertion of the detection probe 2 on the side away from the shell 11, the sealing layer 132 includes a cylindrical sealing sleeve 1321 and a conical sealing sleeve 1322. The conical sealing sleeve 1322 is arranged at one end of the cylindrical sealing sleeve 1321, and the conical sealing sleeve 1322 is located on the side close to the mounting cylinder 14. Correspondingly, the inner wall shape of the sealing cylinder 13 is cylindrical and conical, respectively accommodating the cylindrical sealing sleeve 1321 and the conical sealing sleeve 1322. The inner side of the conical sealing sleeve 1322 is a cylindrical through hole. The closer to the outside, the thicker it is, the greater the extrusion range, and the easier it is to adjust and insert.

[0036] In one embodiment, see Figure 1 、 Figure 2 and Figure 3 In order to improve the leak-proof performance, a liquid accumulation shell 15 is further provided between the sealing cylinder 13 and the installation cylinder 14 to retain the liquid that may be brought out after the opening 101 is closed, thereby improving the overall leak-proof effect.

[0037] It is understandable that if the detection probe 2 is not pulled out properly, resulting in the opening 101 being closed by the opening and closing mechanism 12, there will be a large amount of liquid in the shell 11. After the detection probe 2 is pulled out, there may be a risk of overflowing from the sealing tube 13. Therefore, a liquid storage shell 15 is provided between the sealing tube 13 and the mounting tube 14 to accommodate this part of the liquid and prevent it from leaking.

[0038] Specifically, a liquid drain port 1501 is provided at the bottom of the liquid storage housing 15 , and a liquid storage box 1502 is clamped on the liquid drain port 1501 for accommodating the liquid. The liquid storage box 1502 can be directly removed for cleaning.

[0039] Furthermore, a drainage hole 1101 is opened at the bottom of the shell 11 , and a sealing plug 1102 is threadedly connected to the inner side of the drainage hole 1101 . The sealing plug 1102 can be removed to discharge any liquid that may be retained in the shell 11 .

[0040] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the present invention is described in detail: during installation, the detection probe 2 is inserted into the mounting tube 14, the sealing tube 13, the through hole 102, the shell 11 and the opening 101 in sequence, and is embedded in the mounting hole on the reactor body 3, and then the threaded portion 201 is threadedly connected to the mounting tube 14; during disassembly, the detection probe 2 is first rotated to release the threaded connection between the threaded portion 201 and the mounting tube 14, and then the detection probe 2 is pulled out and the transparent glass 106 is observed. When the tail end of the detection probe 2 moves into the shell 11, the sealing plate 121 is pushed down to make the sealing plate 121 seal the opening 101, and then the detection probe 2 is completely pulled out of the sealing tube 13 until it is separated from the entire docking part 1, thereby achieving the disassembly of the detection probe 2 without leakage.

[0041] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
