Technical Field
[0001] This utility model relates to the field of chemical machinery technology, and in particular to a leak-proof device for the external coil of a reaction vessel. Background Technology
[0002] Reactors are key equipment in chemical production, used to realize chemical or physical reactions of materials. In many reaction processes, precise temperature control of the reaction vessel is required. Therefore, the reactor body needs to be connected to an external coil to circulate the heat transfer medium to achieve heating or cooling functions.
[0003] The connection between the reaction vessel and the external coil must be sealed to prevent leakage of materials inside the reaction vessel or heat transfer medium in the external coil. Existing sealing methods use a structure of flanges, bolts and elastic sealing rings to compress the elastic sealing rings. Mechanical pressure is used to deform the elastic sealing rings and fill the connection gap to achieve physical isolation.
[0004] However, in actual operation, the chemical or physical reactions inside the reactor will produce high or low temperatures. These drastic temperature changes will directly affect the elastic sealing ring at the connection through heat conduction. When the temperature at the connection is too high, it will cause the elastic sealing ring to age, harden, or lose its elasticity at an accelerated rate.
[0005] Furthermore, when the temperature at the connection is too low, the elastic sealing ring material will become brittle and break under equipment vibration or pressure fluctuations. Both excessively high and low temperatures at the connection will eventually lead to seal failure and cause media leakage, which will not only cause material loss but also safety accidents.
[0006] Therefore, this utility model proposes a leak-proof device for the external coil of a reaction vessel to overcome the shortcomings of the prior art. Utility Model Content
[0007] In view of the problem that the existing reactor external coil anti-leakage device relies solely on mechanical compression to achieve passive sealing, which cannot cope with the drastic temperature fluctuations generated during reactor operation, causing the elastic sealing ring to be damaged and fail due to overheating or overcooling, thus leading to media leakage and low reliability, this utility model aims to provide a reactor external coil anti-leakage device with an improved structure that can effectively solve the above problems.
[0008] This utility model provides a leak-proof device for the outer coil of a reaction vessel, including: a fixing frame, a reaction vessel, an outer coil, a sealing mechanism for sealing the connection between the reaction vessel and the outer coil, and a temperature regulating mechanism; The sealing mechanism includes a fixed flange fixed to the right end of the outer coil, an annular sealing groove opened at the left end of the reaction vessel, an elastic sealing ring provided in the annular sealing groove, and a clamping flange provided between the reaction vessel and the fixed flange. Furthermore, the temperature regulation mechanism includes a temperature sensor located on the inner wall of the reaction vessel, a temperature compensation box and a water pump fixedly connected to the outside of the connection point. The temperature sensor, the water pump and the temperature compensation box are combined by controlling the circulation of the medium. The temperature sensor is used to detect the temperature to control the operation of the water pump, and the water pump is used to draw the medium and make the medium flow through the temperature compensation box.
[0009] Preferably, the sealing mechanism further includes a threaded hole, a bolt, and a gasket. The threaded hole is located at the left end of the reaction vessel, and the bolt passes through the fixing flange and the clamping flange in sequence before being inserted into the threaded hole.
[0010] Preferably, the gasket is disposed between the left end of the bolt and the fixing flange.
[0011] Preferably, the fixed flange is T-shaped.
[0012] Preferably, the elastic sealing ring is fixedly connected to the inner wall of the annular sealing groove.
[0013] Preferably, the temperature regulating mechanism further includes a water tank and a heater. The water tank is fixed to the top of the mounting frame, the water pump is used to draw clean water from the water tank, and the heater is fixedly connected to the top of the water tank.
[0014] Preferably, the temperature regulating mechanism further includes a water supply pipe and a return pipe, the water pump is connected to the temperature compensation box through the water supply pipe, and the return pipe connects the temperature compensation box and the water tank.
[0015] Preferably, the water supply pipe is connected to the bottom of the temperature compensation box, and the return pipe is connected to the top of the temperature compensation box.
[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the elastic sealing ring at the connection of the reactor is overheated or undercooled due to drastic changes in reaction temperature, leading to material aging, deformation or damage and leakage. It actively adjusts and maintains the stable working temperature of the sealing components, extends the service life of the sealing ring, and significantly improves the connection safety.
[0017] 2. This utility model uses a sealing mechanism consisting of a fixed flange, a clamping flange, and bolts to reliably mechanically compress the elastic sealing ring. In addition, a water circulation temperature compensation box is added around the outside of the connection. This solves the problem that traditional sealing structures rely solely on passive sealing and cannot withstand thermal shock and temperature fluctuations, thus failing. By combining mechanical compression with active thermal management, the device can operate stably for a long time in environments with drastic temperature changes. Attached Figure Description

[0032] As a preferred embodiment, please refer to Figure 1 , Figure 2 and Figure 5 To construct a circulation loop, the water pump 504 is connected to the temperature compensation box 506 via the water supply pipe 505, and the return pipe 507 connects the temperature compensation box 506 and the water tank 502. More preferably, the water supply pipe 505 is connected to the bottom of the temperature compensation box 506, and the return pipe 507 is connected to the top of the temperature compensation box 506.
[0033] Working principle: When connecting the reaction vessel 2 and the outer coil 3, which are fixedly connected to the top of the fixed frame 1, a T-shaped fixing flange 401 is fixedly connected to the right end of the outer coil 3. Then, the outer coil 3, together with the fixing flange 401, is moved to the right until the internal channels of the reaction vessel 2 and the outer coil 3 are on the same straight line. Since the left end of the reaction vessel 2 has an annular sealing groove 402, and an elastic sealing ring 403 is fixedly connected to the inner wall of the annular sealing groove 402, a clamping flange 404 is set between the fixing flange 401 at the right end of the reaction vessel 2 and the outer coil 3. The squeezing force when the reaction vessel 2 and the outer coil 3 are connected is used to squeeze and deform the elastic sealing ring 403 in the annular sealing groove 402, so as to achieve a seal between the clamping flange 404 and the reaction vessel 2. Then, multiple bolts 406 are removed and installed from the left end of the fixed flange 401 to the right, so that the bolts 406 pass through the fixed flange 401 and the clamping flange 404 in sequence, and finally are inserted into the multiple threaded holes 405 opened at the left end of the reaction tank 2, thus realizing the connection between the outer coil 3 and the reaction tank 2. A gasket 407 is placed between the left end of the bolt 406 and the fixed flange 401 to reduce the vibration force generated during the operation of the reaction tank 2. The device uses the cooperation of the various components of the sealing mechanism 4 to achieve the seal between the reaction tank 2 and the outer coil 3 by relying on the elastic deformation of the elastic sealing ring 403 itself. Pressure is applied by the clamping flange 404 and the bolts 406 to ensure the tight fit between the elastic sealing ring 403 and the reaction tank 2, the fixed flange 401 and the outer coil 3. After the reaction vessel 2 and the external coil 3 are connected, a chemical or physical reaction begins to occur inside the reaction vessel 2, causing a temperature change at the connection point between the reaction vessel 2 and the external coil 3. Since a temperature sensor 501 is fixedly connected to the left end of the inner wall of the reaction vessel 2, the temperature sensor 501 can detect the temperature inside the reaction vessel 2 in real time. When the temperature inside the reaction vessel 2 is high, it controls the start of the water pump 504 fixed to the top of the mounting bracket 1. A water tank 502 is also fixedly connected to the top of the mounting bracket 1. The water tank 502 is filled with clean water, allowing the water pump 504 to draw water from the tank after startup. This water is then transported through the water pipe 505 into the temperature compensation box 506, flowing from the bottom of the box. The temperature compensation box 506 is fixedly connected to the fixing flange 401, pressing the flange 404 and the outer side of the connection point on the left end of the reaction vessel 2. The water pump 504 can then be used to... 4. The extracted clean water is used to cool the connection between the reaction tank 2 and the external coil 3 to prevent the elastic sealing ring 403 from being damaged due to overheating. When there is too much clean water in the temperature compensation box 506, the excess clean water can be transported from the top of the temperature compensation box 506 to the water tank 502 through the return pipe 507. When the temperature in the reaction tank 2 is too low, the heater 503 is fixedly connected to the top of the water tank 502 to heat the clean water in the water tank 502. Then, the heated clean water is extracted again by the water pump 504 to heat the connection between the reaction tank 2 and the external coil 3. Thus, the device can use the cooperation of the various components of the temperature regulation mechanism 5 to regulate the temperature of the various components at the connection between the reaction tank 2 and the external coil 3, and prevent the elastic sealing ring 403 from being damaged by the temperature.
