Description

Technical Field

[0001] This utility model relates to the field of chemical reactor technology, specifically to a multi-safety interlock protection structure for chemical reactors. Background Technology

[0002] A chemical reaction vessel is a device used for conducting chemical reactions, widely applied in the chemical industry, materials science, bioengineering, energy development, and environmental protection. It typically consists of a vessel body, a stirrer, a heating device, and a cooling device, capable of withstanding high-temperature and high-pressure environments to ensure the stability and repeatability of reaction conditions. It is not only the core site of chemical reactions but also a key factor determining product quality and production efficiency. The working principle of the reaction vessel is based on the chemical reaction of materials under specific temperature, pressure, and stirring conditions. During operation, reactants are first added to the vessel in proportion, and the stirring device thoroughly mixes the materials and accelerates the reaction rate. Simultaneously, the temperature inside the vessel is regulated by a heat transfer device to maintain optimal reaction conditions. Throughout the process, various parameters are monitored by instruments to ensure the reaction proceeds smoothly until completion.

[0003] Some traditional reactor lid locking devices are simply designed, relying on a single spiral structure or a simple snap-fit ​​structure. During the reaction process, especially when the internal pressure fluctuates or is subjected to external vibration, they are prone to loosening, leading to a decrease in sealing performance. This may cause toxic, harmful, flammable, and explosive substances to leak out, posing a serious threat to the lives of operators and the surrounding environment. In view of this, we propose a multi-layered safety interlocking protection structure for chemical reactors. Utility Model Content

[0006] By adjusting the combined action of the locking component and the auxiliary component, the lid can be fully locked while the start of the drive motor can be controlled.

[0007] As a further improvement to this technical solution, a baffle is installed inside the movable groove, and the adjustment and locking assembly includes a support rod and a limiting block.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-3 As shown, this embodiment provides a multi-safety interlock protection structure for a chemical reactor, including a reactor body 100. Considering that the locking device of the lid 101 in some traditional reactors is simple in design, relying only on a single spiral structure or a simple snap-fit ​​structure, loosening can easily occur during the reaction process, especially when the pressure inside the reactor fluctuates or is subjected to external vibration, leading to a decrease in sealing performance and potentially causing leakage of toxic, harmful, flammable, and explosive substances, posing a serious threat to the life safety of operators and the surrounding environment. Therefore, the following is specifically provided: A lid 101 is threadedly connected to the top of the reactor body 100. A rotating handle 1010 is installed on the upper surface of the lid 101. A movable groove 1013 is opened inside the rotating handle 1010, and an adjustment and locking component 200 is installed inside the movable groove 1013. A support column 1011 is installed at the top of the lid 101, and a drive motor 1012 is installed at the top of the support column 1011. An auxiliary component 300 is installed on the side wall of the support column 1011, wherein:

[0021] By adjusting the combined action of the locking component 200 and the auxiliary component 300, the lid 101 can be fully locked while the start of the drive motor 1012 can be controlled.

[0022] The improvement in this embodiment is as follows:

[0023] By adjusting the precise fit between the locking component 200 and the auxiliary component 300, a dual interlocking mechanism is achieved for locking the vessel lid 101 and starting the drive motor 1012. This design effectively prevents the motor from starting when the vessel lid 101 is not locked, preventing the vessel lid 101 from accidentally opening due to vibrations or pressure generated during stirring. This avoids the splashing of high-temperature, high-pressure, and corrosive substances, which could cause injury to operators and greatly improves the safety of equipment operation.

[0024] To achieve complete locking of the vessel lid 101 while simultaneously controlling the start of the drive motor 1012, a baffle 1014 is installed inside the movable slot 1013. The adjusting locking assembly 200 includes a support rod 201 and a limiting block 202. One end of the support rod 201 is fixedly connected to the side wall of the limiting block 202. An elastic spring 2010 is provided on the axial side of the support rod 201. One end of the elastic spring 2010 is fixedly connected to the side wall of the limiting block 202, and the other end is fixedly connected to the side wall of the baffle 1014. The other end of the support rod 201 passes through the baffle 1014 and is movably connected to the baffle 1014. A limiting plate 2011 is fixedly connected to the end of the support rod 201. When it is necessary to lock the vessel lid 101, the support rod 201 cooperates with the baffle 1014 under the action of the elastic spring 2010, so that the limiting block 202 can be accurately inserted into the limiting slot 3010 of the auxiliary assembly 300, thereby achieving a tight lock on the vessel lid 101. This locking method can withstand certain pressure and tension, ensuring that the vessel lid 101 will not accidentally loosen during the reaction process. The auxiliary component 300 includes a mounting base 301 with a limiting groove 3010 on its surface. The limiting groove 3010 cooperates with the limiting block 202, and a start button 3011 is installed inside the limiting groove 3010. The locking component 200 and the auxiliary component 300 are connected through the cooperation of the limiting block 202 and the limiting groove 3010. Only when the vessel lid 101 is fully locked, i.e., when the limiting block 202 is accurately inserted into the limiting groove 3010, can the start button 3011 on the auxiliary component 300 be triggered, thus allowing the drive motor 1012 to start. This design effectively prevents accidental motor start-up when the vessel lid 101 is not locked, ensuring operational safety.

[0025] In practical use, the multi-safety interlock protection structure of this chemical reactor involves the operator adding an appropriate amount of reaction material into the reactor body 100 through the feed inlet. The operator uses one hand to push the limiting block 202 into the movable groove 1013 via the elastic action of the elastic spring 2010, while simultaneously rotating the handle 1010 to tighten the reactor lid 101 downwards, ensuring a tight connection between the lid 101 and the reactor body 100. When the lid 101 is rotated to the appropriate position, the limiting block 202 is aligned with the limiting groove 3010 on the auxiliary component 300. At this point, the operator releases their hand from the limiting block 202 and, again using the elastic action of the elastic spring 2010, gradually moves the limiting block 202 closer to the limiting groove 3010 in the auxiliary component 300. When the limiting block 202 is fully inserted into the limiting groove 3010, the reactor lid 101 is completely locked. During this process, the elastic spring 2010 acts as a buffer and positioning element, ensuring that the limiting block 202 can be accurately inserted into the limiting groove 3010. As the vessel lid 101 is locked, the limiting block 202 inserts into the limiting groove 3010, triggering the start button 3011 on the auxiliary component 300. After the start button 3011 is triggered, it sends a signal to the drive motor 1012 control system. Upon receiving the start signal, the drive motor 1012 begins to operate, driving the agitator inside the reactor to rotate via a transmission device. The agitator begins to stir the raw materials, ensuring thorough mixing and promoting the chemical reaction.
