Description

Technical Field

[0001] This utility model belongs to the field of chemical synthesis technology, specifically relating to a keto acid synthesis reactor. Background Technology

[0002] In the field of chemical synthesis, keto acids, as an important class of organic acids, have a wide range of applications in many industries such as food, medicine, and agriculture. For example, in medicine, compound keto acid tablets can be used to treat chronic liver and kidney failure; in the food industry, they can be used in products such as functional beverages. At present, there are various methods for synthesizing keto acids, including chemical synthesis, fermentation and enzymatic synthesis. Because the stirring components are fixed, cleaning the inside of the reactor, especially around the stirring components and in remote corners, is extremely difficult after the reaction is complete. Materials are prone to remain in these locations, and over time, these residues may oxidize and deteriorate, affecting not only the service life of the reactor but, more seriously, contaminating the new reaction materials during the next batch of production. This leads to a decrease in product purity, making it difficult to meet the extremely high quality requirements of applications such as pharmaceutical-grade keto acids. Summary of the Invention

[0003] To address the above problems, the purpose of this utility model is to provide a keto acid synthesis reactor that solves the aforementioned issues.

[0004] To achieve the above objectives, a keto acid synthesis reactor includes a reactor body. The reactor body is equipped with a stirring assembly for mixing reactants. The stirring assembly includes a central rod, a locking rod, an outer stirring rod, and a crossbar. The crossbar is slidably connected to one end of the locking rod. A mounting sleeve corresponding to the outer stirring rod and the crossbar is installed on the top of the reactor body. A sealing block is installed on the inner wall of the mounting sleeve. An upper guide rail and a lower guide rail are respectively installed at the bottom and top of the reactor body's inner cavity. Slide tracks are provided on the upper and lower guide rails to slidably connect to both ends of the outer stirring rod. An arc-shaped plate communicating with one of the upper guide rails is installed at the bottom of the sealing block.

[0005] Preferably, a motor is installed on the top of the reactor body, and the drive end of the motor is connected to the bottom end of the central rod.

[0006] Preferably, one end of the crossbar at the bottom is provided with a slot that matches the locking rod, and the lower guide rail is provided with a connecting hole that communicates with the slide rail.

[0007] Preferably, the slide is matched with the bottom of the outer stirring rod.

[0008] Preferably, the inner cavity of the reactor body is equipped with a positioning assembly for limiting the outer end of the crossbar at the top, the positioning assembly including a mounting ring, a limiting ring and a support rod.

[0009] Preferably, the outer end of the crossbar slides between the two limiting rings, and the limiting rings and the mounting ring are connected by a plurality of support rods.

[0010] This utility model has the following beneficial effects: Under the constraints of the upper and lower guide rails and the slide, the stirring assembly, in conjunction with the vertical engagement of the clamping rod and the crossbar, ensures stable sliding of the stirring assembly. At the same time, the sealing block inside the installation sleeve can be separated, and the top constraint of the outer stirring rod on the upper guide rail can be released through the arc plate. The outer stirring rod and the crossbar can be pulled upwards directly, allowing the entire assembly to be removed from the reactor body. This facilitates thorough cleaning of the outer wall and connection points of the outer stirring rod and the crossbar, and also allows direct rinsing of areas inside the reactor body that were previously covered by the stirring assembly, completely preventing residual materials from oxidizing and deteriorating or contaminating the next batch of products.

[0013] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way. Example

[0014] like Figure 1—4 As shown: This utility model provides the following technical solution: including a reaction vessel body (1), the reaction vessel body (1) is provided with a stirring assembly (2) for mixing the reaction substances, the stirring assembly (2) includes a central rod (21), a clamping rod (22), an outer stirring rod (23) and a crossbar (24), the crossbar (24) is slidably connected to one end of the clamping rod (22), the top of the reaction vessel body (1) is equipped with an installation sleeve (3) corresponding to the outer stirring rod (23) and the crossbar (24), the inner wall of the installation sleeve (3) is equipped with a sealing block (31), the bottom and top of the inner cavity of the reaction vessel body (1) are respectively equipped with an upper guide rail (32) and a lower guide rail (33), the upper guide rail (32) and the lower guide rail (33) are provided with slides (34) that are slidably connected to both ends of the outer stirring rod (23), and the bottom of the sealing block (31) is equipped with an arc plate (311) that is connected to one of the upper guide rails (32).

[0015] In this embodiment: the reactor body (1) serves as the carrier of the supporting device. By mixing the substrate and catalyst within the reactor body (1), the substrate and catalyst produce keto acids. During the mixing of the catalyst and substrate, the stirring assembly (2) within the reactor body (1) is driven by a motor (11) to rotate the central rod (21). As the central rod (21) rotates, the locking rod (22) mounted on the outer wall of the central rod (21) engages with the crossbar (24) mounted on the outer wall of the outer stirring rod (23). At this time, the rotation of the central rod (21) drives the locking rod (22) to rotate, allowing the outer stirring rod (23) and the crossbar (24) to revolve around the central rod (21), thereby causing the outer stirring rod (23) and the crossbar (24) to revolve around the central rod (21). 24) It can stir the substrate and catalyst to ensure thorough mixing and avoid local over- or under-mixing of substrate. Stirring can also suspend the catalyst evenly in the liquid phase, preventing it from settling at the bottom of the vessel and becoming inactive, thereby improving the reaction efficiency of the substrate and catalyst. At the same time, the lower guide rail (33) installed at the bottom of the inner cavity of the reactor body (1) can slide to the bottom of the outer stirring rod (23) through the slide rail (34) opened at its top. The slide rail (34) opened at the bottom of the upper guide rail (32) installed at the top of the inner cavity of the reactor body (1) can slide to the top of the outer stirring rod (23), so that the outer stirring rod (23) is limited by the upper and lower guide rails (32) and the lower guide rail (33), allowing it to slide steadily and making the stirring assembly (2) rotate. The movement is inside the reactor body (1). After the keto acid synthesis production, after the product is taken out, the seal installed at the bottom of the reactor body (1) is opened, and the top cover of the reactor body (1) is opened to allow the reactor body (1) to be rinsed and the material residue to be cleaned. The stirring component (2) is located in a position far from the opening in order to ensure the stirring effect, which makes it easy to create cleaning dead corners. At this time, it can be installed at the top of the reactor body (1) by the mounting sleeve (3). The sealing block (31) installed on the inner wall of the mounting sleeve (3) is connected to the upper guide rail (32) by the arc plate (311) installed at its bottom. After the connection is made, it can be symmetrical with the lower guide rail (33). After the sealing block (31) is separated, the outer stirring rod (23) slides to the opening position of the mounting sleeve (3). The outer stirring rod (23) and the crossbar (24) can be pulled upwards. The inner diameter of the mounting sleeve (3) is larger than the length of the outer stirring rod (23) and the crossbar (24), so that the outer stirring rod (23) and the crossbar (24) can be pulled upwards as a whole and removed, so as to facilitate the removal of the outer stirring rod (23) and the crossbar (24) for thorough cleaning. The center rod (21) is engaged with the crossbar (24) through the clamping rod (22). The clamping rod (22) is located at the upper and lower openings, so it can be cleaned directly. Thus, the stirring component (2) can be separated from the reactor body (1) separately, so as to facilitate its cleaning and disinfection.

[0016] A motor (11) is installed on the top of the reactor body (1), and the driving end of the motor (11) is connected to the bottom end of the central rod (21). The motor (11) installed on the top of the reactor body (1) can drive the central rod (21) to rotate, so that the clamping rod (22) can push the outer stirring rod (23) and the crossbar (24) to slide between the upper guide rail (32) and the lower guide rail (33), so that the outer stirring rod (23) and the crossbar (24) can stir the substrate and the catalyst.

[0017] The bottom crossbar (24) has a slot (241) that matches the locking rod (22) at one end. The lower guide rail (33) has a connecting hole (35) that communicates with the slide (34). The locking rod (22) corresponds to the top crossbar (24) and the bottom crossbar (24). It is connected to the outer end of the locking rod (22) through the slot (241), so that the outer stirring rod (23) and the crossbar (24) can be engaged on the outside of the central rod (21), so that the stirring assembly (2) slides between the upper guide rail (32) and the lower guide rail (33). The connecting hole (35) is used to prevent the substrate and catalyst from remaining in the slide (34).

[0018] The slide (34) matches the bottom of the outer stirring rod (23); the slide (34) and the bottom of the outer stirring rod (23) match, so that the bottom and top of the outer stirring rod (23) can slide and be limited in the inner wall of the slide (34), so that the outer stirring rod (23) can slide steadily, and the stirring assembly (2) can stir the substrate and catalyst.

[0019] The reactor body (1) is equipped with a positioning component (4) for limiting the outer end of the crossbar (24) at the top. The positioning component (4) includes a mounting ring (41), a limiting ring (42), and a support rod (43). The positioning component (4) can limit the outer end of the crossbar (24) at the top, so that the mounting ring (41) fixes the limiting ring (42) through the support rod (43), and the outer end of the crossbar (24) slides between the mounting rings (41), so that the outer stirring rod (23) and the crossbar (24) can maintain a stable sliding, and the stirring component (2) can stably and fully stir the substrate and catalyst.

[0020] The outer end of the crossbar (24) slides between the two limiting rings (42), and the limiting rings (42) and the mounting ring (41) are connected by a number of support rods (43). The spacing between the limiting rings (42) matches the outer end of the crossbar (24), so that the crossbar (24) can be stably limited between the limiting rings (42), and the limiting rings (42) are supported by the support rods (43), so that the limiting rings (42) can maintain a stable position and horizontally limit the crossbar (24).

[0021] The working principle of this technical solution is as follows: The crossbar (24) is slidably engaged with the locking rod (22) of the center rod (21) through the slot (241), so that the two ends of the outer stirring rod (23) are correspondingly embedded in the slide rail (34) opened on the lower guide rail (33). Then, by rotating the center rod (21) and the locking rod (22), the outer stirring rod (23) slides, and the top of the outer stirring rod (23) slides into the slide rail (34) of the upper guide rail (32). Finally, the sealing block (31) of the mounting sleeve (3) is closed, and the sealing block (31) is aligned with the slide rail (34) opened on the upper guide rail (32) through the arc plate (311), so that the stirring assembly (2) can slide between the slide rail (34) opened on the upper guide rail (32) and the lower guide rail (33), so that the motor (11) drives the center rod (21) to move itself. When the center rod (21) rotates, the clamp rod (22) installed on the outer wall of the center rod (21) engages with the clamp groove (241), causing the outer stirring rod (23) and the cross rod (24) to slide along the slide (34) and revolve around the center rod (21). At this time, the limiting ring (42) limits the outer end of the cross rod (24) to ensure the stable operation of the stirring assembly (2) and avoid the outer stirring rod (23) from shifting due to centrifugal force. When the stirring assembly (2) needs to be cleaned, the top limit of the arc plate (311) on the outer stirring rod (23) is released by separating the sealing block (31), and the outer stirring rod (23) and the cross rod (24) are pulled up to remove them from the slide (34) and take out the vessel body. The outer walls of the outer stirring rod (23) and the cross rod (24) are cleaned separately, which facilitates the separate cleaning operation of the stirring assembly (2).
