Description

Technical Field

[0001] This utility model relates to the field of reactor head technology, and in particular to an anti-loosening reactor head. Background Technology

[0002] As the core equipment for realizing physical or chemical reactions in industrial production, the reaction vessel, through reasonable structural design and parameter configuration, can meet the heating, evaporation, cooling and mixing functions at different speeds required by the process, and is widely used in many fields such as chemical and pharmaceutical industries; During long-term use of the reactor vessel, high-temperature conditions can easily cause the end caps to crack and break. In this case, it is necessary to replace the end caps in a timely manner to ensure the normal operation of the equipment. However, the locking and installation structure of the end caps in traditional reactor vessels is relatively complex, which brings many inconveniences to the disassembly and replacement of the end caps and affects production efficiency. To address the inconvenience of disassembling and assembling end caps, Chinese patent with publication number "CN221808567U" discloses a heat-insulating jacket end cap for a reactor. This device achieves a stable and sealed fit between the end cap and the reactor by engaging a connecting rod on the end cap with a mounting bracket on the reactor's fixing ring. The end cap can be quickly disassembled and assembled by pulling the control bracket, which simplifies the replacement and maintenance process of the end cap to a certain extent. However, the quick-unlocking structure in the existing technology still has obvious defects: its unlocking operation can be achieved by simply pulling the control frame, lacking the necessary locking protection design. Since the reactor is often under high pressure during operation, if the control frame is accidentally touched due to external environmental factors during equipment operation, the unlocking structure will be directly triggered, causing the head to be quickly pushed out or even splashed by the internal high-pressure gas. This situation will not only affect the continuity of production, but may also cause safety accidents. Especially in high-risk scenarios such as chemical reactions, such unlocking methods without locking protection pose great application risks and cannot meet the stringent safety requirements of industrial production. Therefore, it is urgent to optimize and improve the existing reactor head disassembly and assembly structure. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes an anti-loosening reactor head to more accurately resolve the issues described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes an anti-loosening reactor head, including a reactor vessel. A vessel cover is installed on the top of the reactor vessel via a flange. An installation base is fixedly installed on the top of the vessel cover. A sleeve joint is fixedly installed in the middle of the inner side of the installation base. A sealing head is inserted into the sleeve joint. Limiting mechanisms are provided on both sides of the installation base. The limiting end of the limiting mechanism is engaged with the sealing head. An adjustment mechanism is provided on the front of the installation base. The outer side of the adjustment mechanism is connected to the limiting mechanism. An anti-loosening mechanism is fixedly connected to the top of the sealing head. The limiting mechanism includes a sliding groove and a retaining sleeve. The sliding groove is opened on both sides of the top of the mounting base. The retaining sleeve is fixedly installed on both sides of the sealing head. A retaining groove is opened on the inner side of the retaining sleeve. An elastic retaining group is fixedly installed inside the sliding groove. The outer end of the elastic retaining group is inserted into the inside of the retaining groove.

[0005] Furthermore, the elastic card assembly includes a limiting spring, which is fixedly connected to the inner end of the slide groove. A sliding block is fixedly installed on the outer side of the limiting spring. A limiting arm is fixedly installed on the top of the sliding block. A card block is fixedly installed on the upper end of the limiting arm. The end of the card block is inserted into the inner side of the card groove.

[0006] Furthermore, the overall cross-sectional shape of the sliding block is convex, the internal cross-sectional shape of the slide groove is also convex, and the outer corners of the limiting arm and the mounting base are all rounded.

[0007] Furthermore, the adjustment mechanism includes a base block and a guide arm. The base block is fixedly connected to the center of the front of the sleeve joint. A guide block for disassembly and assembly is rotatably connected to the front of the base block. The guide block for disassembly and assembly is generally elliptical. The guide arm is fixedly installed on the lower end of the limiting arm near the guide arm. During use, the limiting spring resets, which drives the locking block to insert into the slot, thereby limiting and locking the sealing head. When disassembly and assembly are required, simply twist the elliptical guide block for disassembly and assembly, which drives the guide block for disassembly and assembly from longitudinal to transverse. At this time, the guide arm can be squeezed to push the limiting arm outward. The outer side of the limiting arm can push the locking block outward and disassemble it from the slot, thereby quickly disassembling and assembling the sealing head. When the guide arm moves outward, the limiting spring can be stretched. After installation, the guide block for disassembly and assembly is released. At this time, the limiting spring resets from the stretched state, which drives the locking block inward. The locking block can then be inserted into the slot to achieve quick locking and positioning.

[0008] Furthermore, a groove is provided on the inner side of the guide arm, and a guide wheel is rotatably connected inside the groove. The inner side of the guide wheel and the inner side of the guide block are in close rolling connection.

[0009] Furthermore, an adjusting shaft is fixedly connected to the top of the guide block, and an adjusting pull ring is fixedly installed on the top of the adjusting shaft. When disassembly and adjustment are required, the adjusting pull ring can be manually moved to quickly adjust the guide block, which squeezes and drives the guide arm to move outward, thereby enabling quick disassembly and adjustment.

[0010] Furthermore, the anti-loosening mechanism includes a top rail, which is fixedly connected to the top of the sealing head. A slider is slidably connected inside the top rail. A limiting shaft is fixedly installed at the front end of the slider. The end of the limiting shaft is inserted into the interior of the adjusting pull ring. An adjusting push plate is fixedly connected to the top of the slider. A magnetic suction plate is fixedly installed on the outer surface of the limiting shaft. The magnetic suction plate and the adjusting pull ring are magnetically attracted. During use, the magnetic suction plate assists in adsorption, which causes the limiting shaft to be inserted into the interior of the adjusting pull ring. At this time, the limiting shaft and the adjusting pull ring limit the movement, thereby assisting in locking and fixing the adjusting guide block for disassembly and assembly, and preventing accidental contact during use that could cause the sealing head to fall off.

[0011] The beneficial effects of this utility model are: 1. During the application of this technical solution, by setting up an elastic locking group and an anti-loosening mechanism, a double-fixed protection can be formed during use. The limit spring in the elastic locking group can continuously push the locking block and the locking slot to ensure that the sealing head is stably attached under high pressure conditions. The anti-loosening mechanism fixes the position of the guide block for disassembly and assembly through the cooperation of the limit shaft and the adjusting pull ring and the adsorption effect of the magnetic plate. Even if the adjusting pull ring is accidentally touched externally, it will not trigger the unlocking action, thereby achieving the effect of preventing the sealing head from loosening or being pushed out by high pressure. This solves the problem of safety hazards caused by mis-locking due to the lack of a locking structure in the existing technology. 2. During the application of this technical solution, by setting up a guide block and guide wheel, the guide block can be adjusted before installation to push the limiting arm outward, ensuring that the sealing head is smoothly covered and installed. During disassembly, it is only necessary to release the anti-loosening mechanism limit and rotate the adjusting pull ring. The guide block can then squeeze the guide arm to drive the limiting arm to move, releasing the locking block. The guide wheel can also reduce friction and make the operation smoother, thereby achieving the effect of quick disassembly and assembly of the sealing head. This solves the problems of complex disassembly and assembly operations or insufficient safety of quick unlocking structures in the existing technology, which affect production efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] A reactor head designed to prevent loosening includes a reactor vessel 1. A vessel cover 2 is mounted on the top of the reactor vessel 1 via a flange. A mounting base 3 is fixedly mounted on the top of the vessel cover 2. A sleeve joint 4 is fixedly mounted on the inner center of the mounting base 3. A sealing head 5 is inserted into the sleeve joint 4. Limiting mechanisms 6 are provided on both sides of the mounting base 3. The limiting end of the limiting mechanism 6 is engaged with the sealing head 5. An adjusting mechanism 7 is provided on the front of the mounting base 3. The outer side of the adjusting mechanism 7 is connected to the limiting mechanism 6. An anti-loosening mechanism 8 is fixedly connected to the top of the sealing head 5. The limiting mechanism 6 includes a sliding groove 61 and a retaining sleeve 62. The sliding groove 61 is located on both sides of the top of the mounting base 3. The retaining sleeve 62 is fixedly installed on both sides of the sealing head 5. A retaining groove 63 is provided on the inner side of the retaining sleeve 62. An elastic retaining group 64 is fixedly installed inside the sliding groove 61, and the outer end of the elastic retaining group 64 is inserted into the retaining groove 63. During the application of this device, by setting up the reactor 1, reactor cover 2, mounting base 3, sleeve joint 4, sealing head 5, limiting mechanism 6 and adjusting mechanism 7, the reactor cover 2 can be installed on the top of the reactor 1 through the flange. Then, the mounting base 3 provides the installation foundation for the sleeve joint 4, limiting mechanism 6 and adjusting mechanism 7. Subsequently, the sealing head 5 is inserted into the sleeve joint 4. The sleeve joint 4 is used to initially position the sealing head 5 to ensure that a preliminary seal is formed between the sealing head 5 and the reactor cover 2. When the sealing head 5 is inserted into place, the limiting mechanisms 6 on both sides of the mounting base 3 begin to function. The elastic retaining group 64 in the limiting mechanism 6... Fixed inside the slide groove 61, its outer end can be directly inserted into the slots 63 of the retaining sleeves 62 on both sides of the sealing head 5. Through the engagement of the elastic retaining group 64 with the slots 63, the sealing head 5 is limited and fixed, preventing displacement of the sealing head 5 during use. At the same time, the adjustment mechanism 7 on the front of the mounting base 3 is connected to the outside of the limiting mechanism 6. When it is necessary to adjust the limiting state of the limiting mechanism 6, the limiting mechanism 6 can be moved by operating the adjustment mechanism 7, such as controlling the engagement or disengagement of the elastic retaining group 64 with the slots 63, thereby meeting the needs of installation, fixation or disassembly and maintenance of the sealing head 5. This structural design not only ensures the stability of the sealing head 5 after installation and prevents it from loosening during the reaction process, but also allows for convenient control of the limiting state through the adjustment mechanism 7. It avoids the problem of complicated head disassembly and assembly in traditional structures, improves the convenience and reliability of the device, ensures the stable operation of the reaction process, and reduces production interruptions or safety hazards caused by head fixing problems.

[0016] Combination Figures 3-5As shown, the elastic locking assembly 64 includes a limiting spring 641, which is fixedly connected to the inner end of the slide groove 61. A sliding block 642 is fixedly installed on the outer side of the limiting spring 641. A limiting arm 643 is fixedly installed on the top of the sliding block 642. A locking block 644 is fixedly installed on the upper end of the limiting arm 643. The end of the locking block 644 is inserted into the inner side of the locking groove 63. The overall cross-sectional shape of the sliding block 642 is convex, and the internal cross-sectional shape of the slide groove 61 is also convex. The outer corners of the limiting arm 643 and the mounting base 3 are rounded. The adjusting mechanism 7 includes a base block 71 and a guide arm 72. The base block 71 is fixedly connected to the center of the front of the sleeve joint 4. A guide disassembly block 73 is rotatably connected to the front of the base block 71. The guide disassembly block 73 is elliptical in shape. The guide arm 72 is fixedly installed on the lower end of the limiting arm 643 near the guide arm 72. During use, the limiting spring 641... 41. Resetting the position allows the locking block 644 to be inserted into the slot 63, thus enabling the sealing head 5 to be locked in place. When disassembly or assembly is required, simply twist the elliptical guide disassembly / assembly locking block 644, which will cause the guide disassembly / assembly guide block 73 to change from longitudinal to transverse. At this time, the guide arm 72 can be squeezed to push the limiting arm 643 outward. The limiting arm 643 will push the locking block 644 outward to disengage from the slot 63, thus enabling quick disassembly or assembly of the sealing head 5. When the guide arm 72 moves outward, the limiting spring 641 can be stretched. After installation, the guide disassembly / assembly guide block 73 can be released. At this time, the limiting spring 641 will reset from the stretched state, which will cause the locking block 644 to move inward. The locking block 644 can then be inserted into the slot 63 to achieve quick locking and positioning. The inner side of the guide arm 72 has a groove 74, and the inside of the groove 74 is rotatably connected to the guide wheel 75. The inner side of the guide wheel 75 and the inner side of the guide disassembly / assembly guide block 73 are in close rolling contact.

[0017] In the above-described embodiments of this application, the device, through the provision of an elastic locking group 64, an adjusting mechanism 7, and related components, enables the sealing head 5 to be fixed in place by relying on the elastic locking group 64 during use. Simultaneously, the adjusting mechanism 7 facilitates the control of the disassembly and assembly process. During use, the limiting spring 641 in the elastic locking group 64 resets, causing the limiting arm 643 fixed to the top of the sliding block 642 to move, thereby allowing the locking block 644 at the upper end of the limiting arm 643 to insert into the slot 63, achieving the limiting engagement of the sealing head 5. Both the sliding block 642 and the sliding groove 61 are convex in shape, ensuring stable movement of the sliding block 642 within the sliding groove 61. The outer corners of the limiting arm 643 and the mounting base 3 are rounded, reducing frictional resistance during use. When the sealing head 5 needs to be disassembled or assembled, simply twist the elliptical guide disassembly and assembly block 73, changing it from longitudinal to transverse. At this time, the guide disassembly and assembly block 73 will press against the guide arm 72, pushing... When the limiting arm 643 moves outward, it causes the locking block 644 to move outward and disengage from the locking groove 63, thereby enabling the quick installation and removal of the sealing head 5. The guide wheel 75, which is rotatably connected in the inner groove 74 of the guide arm 72, rolls against the inner side of the guide block 73, reducing friction when they are in contact and making the extrusion process smoother. When the guide arm 72 moves outward, it will stretch the limiting spring 641. After installation, the guide block 73 is released, and the limiting spring 641 will then release. When the extended state is reset, the locking block 644 moves inward, allowing it to re-insert into the slot 63 for quick locking and positioning. This design ensures the stability of the sealing head 5 after installation through the reset function of the elastic locking block 64, simplifies the disassembly and assembly process through the convenient operation of the adjustment mechanism 7, and enhances the stability and smoothness of component movement by utilizing the convex structure and guide wheel 75. This effectively avoids problems such as inconvenient disassembly and assembly or unstable positioning, and improves the practicality and reliability of the device. Example 2

[0018] Combination Figures 1-5As shown, an adjusting shaft 76 is fixedly connected to the top of the guide block 73, and an adjusting pull ring 77 is fixedly installed on the top of the adjusting shaft 76. The adjusting pull ring 77 is used to quickly adjust the guide block 73 by manually pulling the adjusting pull ring 77 when disassembly and adjustment are required, thereby squeezing and moving the guide arm 72 outward, and thus enabling quick disassembly and adjustment. The anti-loosening mechanism 8 includes a top rail 81, which is fixedly connected to the top of the sealing head 5. A slider 82 is slidably connected inside the top rail 81, and a limit shaft is fixedly installed at the front end of the slider 82. 83. The end of the limiting shaft 83 is inserted into the inside of the adjusting pull ring 77. The top of the slider 82 is fixedly connected to the adjusting push plate 84. The outer surface of the limiting shaft 83 is fixedly installed with a magnetic suction plate 85. The magnetic suction plate 85 and the adjusting pull ring 77 are magnetically attracted. During use, the magnetic suction plate 85 assists in adsorption, which can cause the limiting shaft 83 to be inserted into the adjusting pull ring 77. At this time, the limiting shaft 83 and the adjusting pull ring 77 are used for limiting, which can then help to lock and fix the adjusting guide disassembly block 73, and prevent accidental contact during use that could cause the sealing head 5 to fall off.

[0019] The technical solution described in the above-described embodiments of this application, during the application of this device, by setting an adjusting shaft 76, an adjusting pull ring 77, and an anti-loosening mechanism 8, allows for convenient control of the movement of the guide block 73 during use, while preventing the sealing head 5 from falling off due to accidental contact during use. When it is necessary to disassemble and adjust the sealing head 5, the guide block 73 can be quickly adjusted by manually pulling the adjusting pull ring 77. The adjusting pull ring 77 is fixed to the top of the adjusting shaft 76, and the adjusting shaft 76 is fixedly connected to the top of the guide block 73. Therefore, pulling the adjusting pull ring 77 can drive the guide block 73 to move, thereby causing the guide block 73 to squeeze and move the guide arm 72 outward, realizing the rapid disassembly and adjustment of the sealing head 5. During normal use of the device, the anti-loosening mechanism 8 will play a role. The rail 81 is connected to the top of the sealing head 5. The slider 82, which is slidably connected inside the top rail 81, can be moved by the top adjustment push plate 84. The limiting shaft 83 at the front end of the slider 82 will move with the slider 82 and insert into the adjusting pull ring 77. The magnetic suction plate 85 on the outer surface of the limiting shaft 83 will have a magnetic attraction with the adjusting pull ring 77. The auxiliary attraction of the magnetic suction plate 85 can make the limiting shaft 83 more firmly inserted into the adjusting pull ring 77. At this time, the limiting shaft 83 and the adjusting pull ring 77 cooperate to limit the movement, which can help to lock and fix the adjusting guide disassembly block 73. This avoids the situation where the adjusting pull ring 77 or the guide disassembly block 73 is accidentally touched during use, which may cause the guide disassembly block 73 to malfunction and cause the sealing head 5 to fall off. This ensures the convenience of disassembly and assembly operations and improves the safety and stability of the device during use.

[0020] The working principle and advantages of this utility model are as follows: Before installing the sealing head 5, the guide disassembly block 73 needs to be adjusted to drive the extrusion guide arm 72 to push the limiting arm 643 outward. In specific operation, the adjusting ring 77 is pulled by hand to drive the adjusting shaft 76 to rotate. The rotation of the adjusting shaft 76 causes the guide disassembly block 73 to rotate accordingly. Because the guide disassembly block 73 is elliptical, when its major axis changes from horizontal to vertical, the outer side of the guide disassembly block 73 will interact with the guide wheel in the inner groove 74 of the guide arm 72. 75 contacts and generates a squeezing force. The guide wheel 75 rotates to reduce the friction between the two, so that the guide arm 72 drives the limiting arm 643 to move outward away from the sleeve joint 4 under the squeezing action. When the limiting arm 643 moves outward, it pulls the sliding block 642 to move along the slide groove 61. The movement of the sliding block 642 will stretch the limiting spring 641 in the elastic card group 64 until the card block 644 at the upper end of the limiting arm 643 is completely removed from the coverage of the sleeve joint 4. At this time, the sealing head 5 can be installed. During the installation phase, the reactor 1 and the reactor cover 2 are first connected via a flange. The mounting base 3 is then fixed to the top of the reactor cover 2. The sealing head 5 is then placed over the outside of the sleeve joint 4 and inserted into the sleeve joint 4. The sleeve joint 4 provides initial positioning for the sealing head 5, ensuring a tight seal between the sealing head 5 and the reactor cover 2, preparing for subsequent positioning and fixing. After the sealing head 5 is in place, the retaining sleeves 62 on both sides of the sealing head 5 are released. The adjusting pull ring 77 is then released, and the limiting spring 641 in the elastic retaining group 64 returns to its natural state from its stretched state. The elastic force generated by this spring pushes the sliding block 642 along the sliding groove 61 towards the retaining sleeve 62. The cooperation between the sliding block 642 and the sliding groove 61 ensures that the sliding block 642 will not deviate during its movement, thus ensuring accurate subsequent locking actions. The top limiting arm 643 moves synchronously. The design of the limiting arm 643 and the outer edge of the mounting base 3 reduces frictional resistance during movement. When the card block 644 at the upper end of the limiting arm 643 is inserted into the card slot 63 inside the card sleeve 62, the sealing head 5 completes the initial limiting and fixing. After the initial fixing, the anti-loosening mechanism 8 is operated for secondary locking, pushing the adjusting push plate 84 to drive the slider 82 in the top rail 81 to move. The limiting shaft 83 at the front end of the slider 82 moves with the slider 82 and is inserted into the adjusting pull ring 77. The magnetic suction plate 85 on the outer surface of the limiting shaft 83 and the adjusting pull ring 77 generate a magnetic attraction, making the connection between the limiting shaft 83 and the adjusting pull ring 77 more stable. By limiting the adjusting pull ring 77 with the limiting shaft 83, the position of the guide block 73 is fixed to prevent it from rotating accidentally. After the reactor 1 enters the use stage, the limiting spring 641 in the elastic card group 64 continuously provides an inward elastic force to the sliding block 642, so that the card block 644 always remains inserted into the card slot 63. Even if the reactor 1 is under high pressure, the tight fit between the card block 644 and the card slot 63 can prevent the sealing head 5 from loosening. At the same time, the anti-loosening mechanism 8 restricts the rotation of the adjusting ring 77 and the adjusting shaft 76 through the limiting fit between the limiting shaft 83 and the adjusting pull ring 77, as well as the adsorption effect of the magnetic suction plate 85, thereby fixing the position of the guide disassembly block 73. If the external environment accidentally touches the adjusting ring 77, it will not be able to drive the guide disassembly block 73 to rotate, thus avoiding triggering the unlocking action. When the sealing head 5 needs to be disassembled, replaced, or maintained, first operate the anti-loosening mechanism 8 to release the limit, pull the adjusting push plate 84 outward, and drive the slider 82 to move along the top rail 81 away from the adjusting pull ring 77. When the slider 82 moves, it drives the limit shaft 83 to disengage from the adjusting pull ring 77, and the magnetic connection between the magnetic suction plate 85 and the adjusting pull ring 77 is simultaneously released. At this time, the adjusting pull ring 77 and the adjusting shaft 76 return to a rotatable state. Then, manually pry open the adjusting pull ring 77 to drive the adjusting shaft 76 and the guide disassembly block 73 to rotate. When the long axis of the guide block 73 changes from longitudinal to transverse, its outer side contacts the guide wheel 75, generating a squeezing force. The guide wheel 75 rotates to reduce friction, causing the guide arm 72 to drive the limiting arm 643 to move away from the sleeve 62. The limiting arm 643 pulls the sliding block 642 along the slide groove 61 and stretches the limiting spring 641. At the same time, the locking block 644 moves outward with the limiting arm 643 and disengages from the slot 63. The limiting fixation of the sealing head 5 is then released. After the limiting fixation is released, the sealing head 5 can be pulled out from inside the sleeve joint 4 to complete the process. The disassembly of the sealing head 5 facilitates subsequent replacement or maintenance. This technical solution adds an adjustment guide block 73 to push the limiting arm 643 outward before installation, ensuring that the sealing head 5 can be smoothly covered and installed. Simultaneously, the combination of the elastic locking group 64 and the anti-loosening mechanism 8 provides a double fixing structure, solving the problem of the lack of a locking structure in existing devices in the background art, and avoiding the safety hazard of the head being pushed out or splashed due to accidental contact. The cooperation between the sliding block 642 and the sliding groove 61 ensures stable movement of the sliding block 642, preventing the locking block 644 from shifting and causing limiting failure. The design of the limiting arm 643 and the mounting base 3 at the edges reduces frictional wear and extends the service life of the device. The initial positioning of the sleeve joint 4 improves installation efficiency, and the guide wheel 75 reduces operating force, making disassembly smooth. The entire device retains the advantage of quick disassembly and assembly, while taking into account operational convenience and safety, reducing equipment downtime, and improving production efficiency. This makes the device more practical and reliable in actual applications, better meeting the needs of industrial production for the sealing head of the reactor 1. During the application of this device, the fixed installation of each structure can be selected by bolt installation, welding installation, screw installation or some flexible snap-fit ​​installation. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. The specific requirements can be flexibly selected according to the application requirements. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0021] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
