Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of synthesis reaction kettles, in particular to a synthesis reaction kettle for flumequine. Background Art
[0002] Generally understood, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food.
[0003] As a highly effective and broad-spectrum antibacterial drug, the mechanism of action of flumequine is to inhibit the synthesis of bacterial nucleic acids, thereby blocking the replication process of bacterial DNA and achieving a bactericidal effect. It is widely used in the veterinary field, mainly for treating bacterial respiratory diseases of livestock and poultry, including Escherichia coli, pullorum disease, salmonellosis, typhoid fever, fowl cholera, and staphylococcal disease, etc.
[0004] The production process of flumequine includes: 1. Reaction of fluoroquinoline and benzoylalanine. First, fluoroquinoline and benzoylalanine are added to the reaction kettle and react together to produce flumequine acid. 2. Conversion of flumequine acid to methyl flumequine acid ester. Then, flumequine acid and methyl chloroform are added to the reaction kettle, and sodium hydroxide is used as a catalyst to convert it into methyl flumequine acid ester by the acetal method. 3. Dissolution of methyl flumequine acid ester in ethanol. Ethanol is added to methyl flumequine acid ester and stirred evenly to dissolve it in ethanol.
[0005] Most of the stirring mechanisms in the reaction kettle are fixedly arranged. After long-term use, they are prone to being eroded or affected in other ways, which is inconvenient for replacement and cleaning, thus affecting the purity in the preparation process.
[0006] Based on this, it is necessary to propose a stirring mechanism that can be easily cleaned and replaced. Content of the Utility Model
[0007] The purpose of the utility model is to provide a synthesis reaction kettle for flumequine, so as to solve the above technical problems to at least a certain extent, and to facilitate operations such as cleaning and replacement of the stirring mechanism.
[0008] To achieve the above purpose, the utility model provides the following technical solutions: including a reaction unit, a stirring unit, and a connecting unit.
[0009] Reaction unit, the reaction unit includes a kettle body, a detachable cover body at the top of the kettle body, and four hanging buckles evenly installed in a ring on the cover body.
[0010] Stirring unit, the stirring unit includes a driving motor installed on the top of the cover body, and a stirring mechanism driven to rotate by the driving shaft of the driving motor. The stirring mechanism includes stirring blades and stirring rods. The stirring blades are L-shaped and do not contact the inner wall of the kettle body. The stirring rods are installed on both sides of the stirring blades. The opening direction of the stirring rods facing the stirring blades is open. The opening of the stirring rods is a diversion groove. A number of stirring blocks are fixedly installed inside the diversion groove, and through holes are provided on the side surfaces of the stirring blocks;
[0011] Connecting unit, the connecting unit includes a hoop bolted to the driving shaft, and the central rods on both sides of the hoop are respectively bolted to the stirring blades.
[0012] Preferably, the hoop and the central rod are integrally provided, and two hoops are sleeved on the driving shaft to form a ring.
[0013] Preferably, there are two central rods, and the ends of the two central rods away from the hoop are respectively connected to two stirring blades.
[0014] Preferably, the tails of the stirring blades below are bolted together, and the two stirring blades form a U shape inside the kettle body.
[0015] Preferably, the stirring rods are curved in an arc shape, and the height of the stirring rods near the stirring blades is higher than that of the other ends of the stirring rods.
[0016] Preferably, the surface area of the opening at the end of the drainage hole near the stirring blade is larger than the surface area of the other end of the drainage hole.
[0017] Preferably, the stirring blades and the stirring rods do not contact the inner wall of the kettle body during rotation.
[0018] Preferably, the bottom of the kettle body is switched on and off at the discharge port by means of a regulating valve.
[0019] Compared with the prior art, the beneficial effects of the present utility model are:
[0020] 1. When the present utility model is used, the cover body can be pulled up by connecting the chain on the hydraulic mechanism to the hanging buckle, and the stirring unit and the connecting unit can be pulled up together. Since the hoop, the central rod and the stirring blade are all connected by bolts, it is convenient to disassemble the stirring unit and the connecting unit for cleaning or replacement, which is convenient for regular maintenance.
[0021] 2. When the utility model is in use, the driving motor and the driving shaft can drive the hoop and the central rod to rotate, further driving the stirring blades and the stirring rods to rotate. The U-shaped arrangement after the combination of the stirring blades can effectively stir the substances within a certain height range in the kettle body, greatly increasing the contact area with the substances inside the kettle body. At the same time, the materials enter the diversion groove. Under the action of centrifugal force during rotation, the materials will contact the stirring blocks. Since there are gaps between the stirring blocks and the inner wall of the diversion groove, the flow rates of the materials in the range are different. And when the materials pass through the drainage holes, because the materials move from a hole with a larger area to a hole with a smaller area, the flow rate changes, and there are flow rate changes in multiple areas, causing a turbulence effect, which can effectively stir and mix the materials more evenly.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0033] Please refer to Figures 1-5 , the present invention provides a technical solution: a synthesis reactor for flumequine, including a reaction unit 100, a stirring unit 200 and a connection unit 300.
[0034] The reaction unit 100, the reaction unit 100 includes a kettle body 110, the bottom of the kettle body 110 is switched by a regulating valve for the discharge port, a detachable cover body 120 at the top of the kettle body 110, and four lifting hooks 121 uniformly installed in a ring shape on the cover body 120.
[0035] Among them, the kettle body 110 is a conventional synthesis reactor without other special functions and will not be elaborated here; the discharge port at the bottom of the kettle body 110 is a conventional discharging mechanism of the reactor without other special functions and will not be elaborated here. Among them, the four lifting hooks 121 on the cover body 120 can cooperate with a traction mechanism such as a chain, and the traction machine can lift or lower the cover body 120, the devices on the cover body 120 and the mechanisms connected thereto together.
[0036] Refer to Figure 1 , Figure 2 and Figure 3 , in a preferred embodiment, the connection unit 300, the connection unit 300 includes a hoop 310 connected to the drive shaft 211 by bolts 330, the hoop 310 and the central rod 320 are integrally provided, two hoops 310 are sleeved on the drive shaft 211 to form a ring, and the central rods 320 on both sides of the hoop 310 are respectively connected to the stirring blades 220 by bolts 330. There are two central rods 320, and the ends of the two central rods 320 far from the hoop 310 are respectively connected to two stirring blades 220.
[0037] By connecting the hoop 310 to the drive shaft 211 and then fixing the hoop 310 on the drive shaft 211 by bolts 330, the drive shaft 211 can drive the hoop 310 to rotate, and the central rods 320 at both ends of the hoop 310 are respectively connected to the stirring blades 220. The bottoms of the two stirring blades 220 are connected together by bolts 330 to keep fixed, so that the stirring blades 220, the central rods 320, the hoop 310 and the drive shaft 211 form a stable mechanism, and further enable the stirring blades 220 to perform stirring work.
[0038] Refer to Figure 1 and Figure 4 In a preferred embodiment, there is a stirring unit 200. The stirring unit 200 includes a driving motor 210 installed on the top of the cover body 120, and a stirring mechanism driven to rotate by a driving shaft 211 of the driving motor 210. The stirring mechanism includes a stirring blade 220 and a stirring rod 230. The stirring blade 220 is arranged in an L shape and does not contact the inner wall of the kettle body 110. The tail ends below the stirring blades 220 are connected together by bolts 330. Two stirring blades 220 form a U shape and are inside the kettle body 110. The stirring rod 230 is installed on both sides of the stirring blade 220. When the stirring blade 220 and the stirring rod 230 rotate, they do not contact the inner wall of the kettle body 110.
[0039] The driving motor 210 drives the stirring blade 220 and other mechanisms to rotate through the driving shaft 211, and the stirring blade 220 does not contact the inner wall of the kettle body 110. That is, there will be no wear or mutual scraping, so that the overall unit can be used for a longer time. Among them, the stirring rod 230 only stirs the material inside the kettle body 110 and does not contact the kettle body 110, so there is no obstruction during stirring, and its rotation speed will not change due to non-subjective factors.
[0040] Refer to Figure 1 and Figure 4 In a further preferred embodiment, the stirring rod 230 is arranged in an arc shape, and the height of one end of the stirring rod 230 near the stirring blade 220 is higher than the other end of the stirring rod 230.
[0041] The opening direction of the stirring rod 230 towards the stirring blade 220 is open. The arc-shaped setting of the stirring rod 230 enables the material therein to always flow downward and be discharged. When the rotation stops, the material in the stirring rod 230 can also flow down due to the inclination angle, reducing the residue of the material on the stirring rod 230.
[0042] Refer to Figure 1 and Figure 4 In a further preferred embodiment, the opening of the stirring rod 230 is a diversion groove 231. A number of stirring blocks 2311 are fixedly installed inside the diversion groove 231. Through drainage holes 23111 are arranged on the side surface of the stirring block 2311. The surface area of the opening of one end of the through drainage hole 23111 near the stirring blade 220 is larger than the surface area of the other end of the through drainage hole 23111.
[0043] Through a plurality of stirring blocks 2311 which can rotate along with the stirring blade 220, it is possible to prevent the material from sinking and maintain its activity. When the material enters the diversion channel 231, under the action of centrifugal force during rotation, the material will come into contact with the stirring blocks 2311. Since there are gaps between the stirring blocks 2311 and the inner wall of the diversion channel 231, the flow rates of the materials in the range are different. And when the material passes through the diversion holes 23111, since the material moves from a hole with a larger area to a hole with a smaller area, its flow rate changes, and there are flow rate changes in multiple areas, resulting in a turbulence effect, which can effectively stir and mix the materials more evenly.
