Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling vessel technology, and more specifically, to a cooling vessel with a pressure relief structure. Background Technology
[0002] In current manufacturing, due to the numerous processing steps, most liquid materials require high-temperature treatment or temperature increases during production. When processing such high-temperature liquid materials, the excessively high temperature necessitates cooling before proceeding to the next processing step to bring the liquid to a suitable processing temperature for subsequent steps. A cooling vessel mainly consists of a vessel body, jacket, agitator, transmission device, feed port, discharge port, and thermometer. The main difference between a cooling vessel and a reaction vessel lies in the structure of its vessel body and jacket. The jacket can be filled with cold or hot water to achieve rapid cooling or heating.
[0003] During the heating process of liquid materials in a vessel, the liquid materials generate steam upon heating, thereby increasing the pressure inside the vessel. If the excess pressure is not released in time, the vessel is prone to damage or explosion due to excessive pressure. To address this, we propose a cooling vessel with a pressure relief structure. Utility Model Content
[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a cooling vessel with a pressure relief structure.

[0027] For details, please refer to Figure 1 , Figure 3 and Figure 5 The cooling mechanism 4 includes a heat exchange box 15 fixedly sleeved on the outside of the pressure relief pipe 3 and a serpentine heat exchange copper tube 16 fixedly sleeved on the inside of the pressure relief pipe 3. The end of the serpentine heat exchange copper tube 16 extends through the inside of the heat exchange box 15 to the outside of the heat exchange box 15. A support frame 17 is fixedly connected to the bottom surface of one end of the heat exchange box 15. A placement groove 18 is opened on the top surface of the support frame 17. A water collection box 19 is placed in the inner cavity of the placement groove 18. The water collection box 19 is located directly below one end of the serpentine heat exchange copper tube 16.
[0028] In this embodiment, the water generated by the cooling steam in the serpentine heat exchange copper tube 16 is collected using the water collection box 19, and the inner cavity of the heat exchange box 15 is pre-filled with coolant.
[0029] For details, please refer to Figure 2 A jacket 22 is fitted on the outside of the vessel body 1. A drain pipe 23 is provided on one side of the jacket 22, and an inlet pipe 24 is provided at the bottom of the jacket 22.
[0030] In this embodiment, hot water and cold water are introduced into the jacket 22 through the inlet pipe 24. The hot water is used to heat the material in the vessel 1, and the cold water is used to cool the material in the vessel 1. The water is discharged through the drain pipe 23.
[0031] For details, please refer to Figure 2 The top of the vessel body 1 is provided with a feeding port 25, and the bottom of the vessel body 1 is fixedly installed with a discharge valve 26, the top of which extends into the inner cavity of the vessel body 1.
[0032] In this embodiment, the liquid material to be processed is added to the reactor body 1 through the feed port 25, and the reacted material in the reactor body 1 is discharged through the discharge valve 26.
[0033] For details, please refer to Figure 5 A threaded plug 20 is threadedly installed on the top surface of the heat exchange box 15, and a drain valve 21 is fixedly installed on the bottom of the heat exchange box 15, with the top end of the drain valve 21 extending into the inner cavity of the heat exchange box 15.
[0034] In this embodiment, the coolant in the heat exchange box 15 is drained through the drain valve 21, and coolant is added to the heat exchange box 15 by removing the threaded plug 20, thereby replacing the coolant in the heat exchange box 15.
[0035] For details, please refer to Figure 3 The screw 11 is threaded with a fastening nut 14 on its outer side, and the bottom surface of the fastening nut 14 is in contact with the top surface of the pressure relief cylinder 2.
[0036] In this embodiment, the screw 11 is fixed by the cooperation between the fastening nut 14, the screw 11 and the pressure relief cylinder 2, so as to ensure the stability of the screw 11.
[0037] Working principle: In use, the liquid material to be processed is first placed into the inner cavity of the vessel body 1 through the feeding port 25. Hot water is introduced into the jacket 22 through the liquid inlet pipe 24. The hot water in the jacket 22 heats the liquid material in the vessel body 1. When the liquid material is heated and generates steam, the pressure in the inner cavity of the vessel body 1 increases. When the pressure in the inner cavity of the vessel body 1 reaches a certain pressure, the steam pushes the pressure relief plate 7, the lifting column 8, and the lifting plate 9 upward. At the same time, the spring 10 is compressed, so that the high-pressure steam is introduced from the pressure relief cylinder 2 and the pressure discharge pipe 3 into the serpentine heat exchange copper tube 16, so that the high-pressure steam is discharged from the end of the serpentine heat exchange copper tube 16, thereby venting the inner cavity of the vessel body 1. In addition, when steam flows in the serpentine heat exchange copper tube 16, it uses the coolant in the heat exchange box 15 and the high-pressure steam in the serpentine heat exchange copper tube 16 for heat exchange, avoiding the danger to the surrounding personnel when the high-temperature steam is discharged. In addition, the water collection box 19 collects the liquid generated by condensation in the serpentine heat exchange copper tube 16. In addition, when depressurizing the vessel body 1 using the pressure relief cylinder 2 and the pressure relief pipe 3, the knob 12 can be turned to drive the screw 11 to rotate, and the screw 11 drives the extrusion plate 13 to move up and down, thereby changing the compression of the spring 10 between the extrusion plate 13 and the lifting plate 9, and thus changing the thrust that the pressure relief plate 7 needs to overcome to move up, so as to adjust the pressure relief.
[0038] After the liquid material in the vessel 1 reacts, cold water is introduced into the inner cavity of the jacket 22 through the liquid inlet pipe 24. The cold water is used to cool down the liquid material in the vessel 1. The cooled material is then discharged from the discharge valve 26.
[0039] 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 its improved concept should be covered within the protection scope of the present utility model.
