Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and specifically provides a windowed reaction vessel. Background Technology

[0002] High-pressure sight glass reactors are important chemical reaction equipment, widely used in chemical, pharmaceutical, food, environmental protection, and new energy fields. During the reaction process, different reagents and catalysts can be added to the high-pressure sight glass reactor to achieve specific chemical reactions. To ensure the smooth progress of the reaction and the safety of the equipment, high-pressure sight glass reactors need to possess characteristics such as high pressure resistance, high sealing performance, and high safety. Among these, the sealing of the high-pressure sight glass is one of the key aspects.

[0003] The existing sealing principle of high-pressure sight glass mainly utilizes the clamping force of the flange face and gasket to tightly fix the glass window to the vessel body, thereby preventing the medium from entering the high-pressure sight glass. However, in order to achieve a good sealing effect, it is necessary to ensure the machining accuracy and flatness of the flange face and gasket, and to use high-strength bolts to ensure that the flange face and gasket fit tightly together.

[0004] Currently, high-pressure sight glasses typically use either metal or non-metal gaskets for sealing. Metal gaskets, such as stainless steel, titanium, and Monel gaskets, offer good corrosion resistance and high-temperature performance, but their compressibility and resilience are poor. Non-metal gaskets, such as fluororubber and PTFE gaskets, while possessing good compressibility and resilience and better adaptability to flange surface unevenness, suffer from poor high-temperature resistance. Therefore, regardless of whether metal or non-metal gaskets are used, leaks are likely to occur after prolonged use.

[0005] Accordingly, there is a need in the art for a new type of sight glass reactor to solve the problem of poor sealing of the high-pressure sight glass in existing sight glass reactors. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of poor sealing of the high-pressure window of the existing window reactor.

[0007] This utility model provides a viewing window reactor, which includes a reactor body, a lens, and a viewing window connector. A reaction chamber is provided in the reactor body. The lens is disposed between the viewing window connector and the reaction chamber. The viewing window connector is connected to the outer wall of the reactor body, and one end face of the viewing window connector abuts against the lens. A viewing channel is provided on the viewing window connector. The two sides of the lens are the viewing channel and the reaction chamber, respectively. The pressure in the reaction chamber acts on the lens, causing the lens and the viewing window connector to be pressed together to achieve a squeeze seal between them.

[0008] When adopting the above technical solution, the sealing principle of the viewing window reactor of this utility model is to use the pressure inside the reaction chamber to apply a reverse force to the lens, thereby making the viewing window connector and the lens fit tightly together, thus achieving a hard seal between them. The advantage of the hard seal structure between the viewing window connector and the lens is that it avoids the risk of leakage caused by factors such as the compression amount of the sealing gasket, poor resilience, poor high temperature resistance, and instantaneous increase in pressure inside the reaction chamber. Moreover, the sealing effect improves as the pressure inside the reaction chamber increases.

[0009] In the optional technical solution of the above-mentioned viewing window reactor, the viewing window reactor further includes a lens mounting base. The lens mounting base is a shell with openings at both ends. One end of the lens mounting base is provided with an inwardly extending flange. The lens is placed inside the lens mounting base and abuts against the flange. The lens mounting base and the viewing window connector are connected so that the lens is pressed against the end face of the viewing window connector under the action of clamping force to achieve pre-sealing.

[0010] When the above technical solution is adopted, before the lens and observation window connector are installed on the vessel body, the lens is restricted to the observation window connector by the lens mounting seat for pre-sealing and to facilitate subsequent installation.

[0011] In the optional technical solution of the above-mentioned viewing window reactor, the lens mounting base and the viewing window connector are respectively provided with corresponding matching threads so that the lens mounting base and the viewing window connector are connected by threads.

[0012] When the above technical solution is adopted, the threaded connection between the lens mounting base and the observation window connector not only facilitates assembly, but also allows the lens to fit more tightly against the end face of the observation window connector.

[0013] In the above-mentioned optional technical solution of the observation window reactor, an installation channel is provided inside the reactor body, the installation channel connects the outside of the reactor body and the reaction chamber, the lens mounting base is disposed in the installation channel, and the observation window connector is located outside the reactor body and connected to the reactor body.

[0014] When the above technical solution is adopted, the installation channel is used to accommodate the installation lens and the lens mounting base. The installation channel is connected to the reaction chamber so as to fix the observation window connector to the vessel body from the outside of the vessel body.

[0015] In the above-mentioned optional technical solution of the observation window reactor, the observation window connector includes a first boss, and a second boss is formed on the end face of the first boss. The first boss abuts against the outer wall of the reactor body and is connected to the reactor body. The second boss is connected to the lens mounting seat, and the end face of the second boss abuts against the lens. The second boss and the lens mounting seat extend into the mounting channel.

[0016] When the above technical solution is adopted, the first boss is used to connect the vessel body and the second boss is used to abut the lens, so as to simplify the structure and facilitate installation.

[0017] In the optional technical solution of the above-mentioned windowed reaction vessel, a sealing element is provided between the first boss and the vessel body.

[0018] When the above technical solution is adopted, a sealing element is provided between the first boss and the vessel body to prevent the medium from overflowing from the gap between them.

[0019] In the optional technical solution of the above-mentioned windowed reaction vessel, the first boss and the vessel body are connected by bolts.

[0020] With the above technical solution adopted, the bolt connection between the first boss and the vessel body makes it easier to install and fix it on the outside of the vessel body.

[0021] In the optional technical solution of the above-mentioned window reactor, a third protrusion is formed between the first protrusion and the second protrusion, and there is a certain gap between the outer wall of the third protrusion and the inner wall of the installation channel to facilitate installation.

[0022] When the above technical solution is adopted, there is a certain gap between the outer wall of the third boss and the inner wall of the installation channel, so that the third boss can be smoothly inserted into the installation channel.

[0023] In the optional technical solution of the above-mentioned windowed reaction vessel, the vessel body is further provided with a feeding section, and the feeding section is provided with a feeding chamber communicating with the reaction chamber.

[0024] When the above technical solution is adopted, the feeding section and the feeding chamber are used to feed the reaction medium into the reaction chamber.

[0025] In the optional technical solution of the above-mentioned viewing window reactor, the viewing window connector includes a first boss, and the end face of the first boss near the lens is provided with an annular groove. The lens mounting base and one side wall of the annular groove are connected by threads.

[0026] When the above technical solution is adopted, the lens mounting base is embedded in the annular groove and threadedly connected to one side wall of the annular groove. The viewing window connector fixes the lens mounting base in a non-protruding structure to simplify the structure and save costs.

[0027] Those skilled in the art will understand that the viewing window reactor of this utility model includes a reactor body, a viewing window connector, and a lens. A reaction chamber is provided within the reactor body. The lens is positioned between the viewing window connector and the reaction chamber. The viewing window connector is connected to the outer wall of the reactor body, and one end face of the viewing window connector abuts against the lens. A viewing channel is provided on the viewing window connector. The viewing channel and the reaction chamber are located on opposite sides of the lens. Pressure within the reaction chamber acts on the lens, causing the lens and the viewing window connector to be pressed together to achieve a seal.

[0028] When adopting the above technical solution, the sealing principle of the viewing window reactor of this utility model is to use the pressure inside the reaction chamber to apply a reverse force to the lens, thereby making the viewing window connector and the lens fit tightly together, thus achieving a compression seal between them. The advantage of the hard seal structure between the viewing window connector and the lens is that it avoids the leakage risks caused by factors such as the compression amount of the sealing gasket, poor resilience, poor high temperature resistance, and instantaneous increase in pressure inside the reaction chamber. Moreover, the sealing effect improves as the pressure inside the reaction chamber increases. Attached Figure Description

[0044] like Figure 1 As shown, in order to solve the problem of poor sealing of the high-pressure window in existing window reactors, this utility model provides a window reactor.

[0045] Reference Figures 1 to 3 The present invention relates to a viewing window reactor comprising a reactor body 1, a viewing window connector 2, and a lens 3. A reaction chamber 11 is provided inside the reactor body 1. The lens 3 is positioned between the viewing window connector 2 and the reaction chamber 11. The viewing window connector 2 is connected to the outer wall of the reactor body 1, and one end face of the viewing window connector 2 abuts against the lens 3. A viewing channel 21 is provided on the viewing window connector 2. The viewing channel 21 and the reaction chamber 11 are located on opposite sides of the lens 3. Pressure within the reaction chamber 11 acts on the lens 3, causing the lens 3 and the viewing window connector 2 to be pressed together to achieve a compression seal.

[0046] The advantages of the above-described configuration are as follows: The sealing principle of the observation window reactor of this invention utilizes the pressure within the reaction chamber 11 to apply a reverse force to the lens 3, thereby ensuring a tight fit between the observation window connector 2 and the lens 3, thus achieving a hard seal between them. The advantage of this hard seal structure between the observation window connector 2 and the lens 3 is that it avoids the risk of leakage caused by factors such as the compression of the sealing gasket, poor resilience, poor high-temperature resistance, and a sudden increase in pressure within the reaction chamber 11. Furthermore, the sealing effect improves as the pressure within the reaction chamber 11 increases. When technicians need to understand the reaction situation within the reaction chamber 11, they can observe it through the observation channel 21 and the lens 3.

[0047] Reference Figures 1 to 3 In one possible embodiment, the sight glass reactor of this invention includes a reactor body 1, a sight glass flange, a lens 3, and a lens mounting base 31. A reaction chamber 11 is provided inside the reactor body 1. Mounting channels 12, connecting the outside of the reactor body to the reaction chamber 11, are respectively provided on the left and right side walls of the reaction chamber 11. The mounting channels 12 are used to accommodate the lens 3 and the lens mounting base 31. A feed section 13 is provided at the top of the reactor body 1, and a feed chamber 131 communicating with the reaction chamber 11 is provided inside the feed section 13. The feed section 13 and the feed chamber 131 are used to feed the reaction medium into the reaction chamber 11.

[0048] Furthermore, referring to Figures 4 to 6 The observation window flange includes a first boss 22, a third boss 24 formed on the first boss 22, and a second boss 23 formed on the third boss 24. A portion of the outer wall of the third boss 24 near the lens 3 is cut off circumferentially to create a gap 241 between the third boss 24 and the inner wall of the mounting channel 12, thereby facilitating the insertion of the third boss 24 and the second boss 23 into the mounting channel 12.

[0049] The first boss 22 is provided with a first mounting hole, and the outer wall of the vessel body 1 is provided with a second mounting hole that mates with the first mounting hole. The second mounting hole is provided with a thread, and the experimenter can hold a bolt outside the vessel body 1 and screw it into the first mounting hole and the second mounting hole to connect the two.

[0050] Furthermore, referring to Figure 4 and Figure 5 The lens mounting base 31 is a housing with openings at both ends. One end of the opening is provided with an inwardly extending flange 311, and the inner wall of the other end of the opening is provided with an internal thread. The lens 3 is placed inside the lens mounting base 31 and abuts against the flange 311.

[0051] The second boss 23 has an external thread that corresponds to the internal thread on the lens mounting base 31. Rotating the lens mounting base 31 allows for a threaded connection between the lens mounting base 31 and the second boss 23. Simultaneously, the lens 3 is pressed between the end faces of the flange 311 and the second boss 23, so that the lens 3 is pressed against the end face of the observation window flange under the clamping force applied by the thread, achieving a pre-seal. This pre-seal facilitates subsequent installation of the observation window flange and the lens 3, and improves the sealing performance between the lens 3 and the observation window flange.

[0052] Reference Figure 3 and Figure 6 The second protrusion 23 and the lens mounting base 31 are then fed into the mounting channel 12. The first protrusion 22 is located outside the vessel body 1, and a sealing element 14 is provided between the first protrusion 22 and the outer wall of the vessel body 1. Bolts are inserted into the first mounting hole and the second mounting hole to connect the two, preventing the medium from leaking to the outside of the vessel body 1. However, it should be noted that those skilled in the art can also provide external threads on the lens mounting base 31 and internal threads on the second protrusion 23 according to actual needs, as long as the lens mounting base 31 can be threadedly connected to the second protrusion 23, and all of these fall within the protection scope of this utility model.

[0053] Reference Figure 3 and Figure 6 An observation channel 21 is provided on the observation window flange, and the two sides of the lens 3 are the observation channel 21 and the reaction chamber 11, respectively.

[0054] When the medium enters the reaction chamber 11, technicians can observe the situation inside the reaction chamber 11 through the observation channel 21 and the lens 3. At the same time, the pressure of the medium inside the reaction chamber 11 acts on the lens 3 to form a counterforce, forcing the end faces of the lens 3 and the observation window flange to press together to achieve a hard seal. As the pressure inside the chamber gradually increases, the sealing between the lens 3 and the observation window flange becomes better, preventing the medium from leaking into the observation channel 21.

[0055] The lens 3 can be made of sapphire, and the width of the sealing surface between it and the observation window flange 1 can be set to 0.5mm. Sapphire provides better sealing between itself and the observation window flange, allowing for long-term use in high-temperature environments of 400℃ and environments of 42MPa.

[0056] However, those skilled in the art can set the material of lens 3 according to actual needs; it can also be quartz or glass, etc. The shape of lens 3 can be circular, rectangular, triangular, etc., and the width of the sealing surface is not limited to 0.5mm. Those skilled in the art can also set it according to actual sealing needs; for example, the width of the sealing surface can also be 0.4mm, 0.6mm, 0.8mm, 1mm, etc., all of which fall within the protection scope of this utility model.

[0057] Reference Figure 7 In another possible implementation, the observation window flange includes a first boss 22, the inner end face of which abuts against both the outer wall of the vessel body 1 and the lens 3. An annular groove 24 is provided on the inner end face of the first boss 22, and an internal or external thread is provided on one side wall of the annular groove 24. The lens mounting seat 31 is provided with a corresponding matching external or internal thread. The lens mounting seat 31 is embedded in the annular groove 24 and connected by threads, thereby simplifying the structure and saving costs. After assembly, only the lens mounting seat 31 and the lens 3 are located within the mounting channel 12.

[0058] Although the observation window connector 2 is described as a circular flange structure in this utility model, the specific structure of the observation window connector 2 is not limited to a flange structure. Those skilled in the art can set the structure of the observation window connector 2 according to actual needs. For example, the observation window connector 2 can also be a connecting plate, and its shape can be rectangular, triangular, elliptical, or other shapes. As long as the observation window connector 2 can play the role of confining the lens 3 within the vessel body 1, it will fall within the protection scope of this utility model.

[0059] In summary, the viewing window reactor of this utility model utilizes the clamping force connected between the lens mounting base 31 and the viewing window connector 2 to pre-seal the lens 3 and the viewing window connector 2. Then, the pressure in the reaction chamber 11 is used to reverse-pressure the lens 3, thereby further sealing the lens 3 and the viewing window connector 2. Therefore, a hard seal can be achieved between the lens 3 and the viewing window connector 2 to prevent leakage, without the need for a sealing gasket.

[0060] As described in the first paragraph of this section, the above embodiments are merely used to illustrate the principle of this utility model and are not intended to limit the scope of protection of this utility model. Without departing from the principle of this utility model, those skilled in the art can adjust the above structure so that this utility model can be applied to more specific application scenarios.

[0061] The connection method between the lens mounting base 31 and the observation window connector 2 is not limited to a threaded connection. For example, in an alternative embodiment, the lens mounting base 31 and the observation window connector 2 can also be riveted, bolted, etc. Those skilled in the art can set the connection method between the lens mounting base 31 and the observation window connector 2 according to actual needs, and all of them fall within the protection scope of this utility model.

[0062] For example, in an alternative embodiment, those skilled in the art can omit the lens mounting base 31 as needed and directly connect the lens 3 to the observation window connector 2. The lens 3 and the observation window connector 2 can be bonded together with structural adhesive, or connected by threads, etc. Alternatively, the lens 3 can be left unconnected to the observation window connector 2, with a limiting part provided between the mounting channel 12 and the reaction chamber 11 to confine the lens 3 between the observation window connector 2 and the limiting part. Therefore, this invention does not impose any restrictions on the connection method between the lens 3 and the observation window connector 2; these methods do not deviate from the principle of this invention and thus fall within the protection scope of this invention.

[0063] Although the structure of the observation window connector 2 in this utility model is described as having three protrusions and one protrusion, those skilled in the art can set the specific structure of the observation window connector 2 according to actual needs. For example, in an alternative embodiment, the observation window connector 2 includes a first protrusion 22, and a second protrusion 23 is formed on the first protrusion 22. As long as the observation window connector 2 can be connected to the lens mounting base 31, and the end face of the observation window connector 2 can abut against the lens 3, the number of protrusions is not limited. These do not deviate from the principle of this utility model and all fall within the protection scope of this utility model.

[0064] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
