Abstract
Description
Technical Field
[0001] This utility model relates to the field of enamel-lined reactors, and more particularly to enamel-lined reactors that facilitate sampling. Background Technology
[0002] In industrial production such as chemical, pharmaceutical, and food processing, enamel-lined reactors are widely used due to their corrosion resistance and high temperature resistance. During the reaction process, accurate and timely acquisition of reactant samples is crucial for monitoring the reaction progress, adjusting process parameters, and ensuring product quality.
[0003] In existing technologies, common enamel-lined reactors typically use built-in delivery pipes for easy sampling. Samples are directly extracted from the reactor and placed into a storage container for subsequent analysis. However, in practice, when reactants enter the subsequent delivery pipeline through the built-in sampling pipe, sedimentation easily occurs inside the pipeline due to differences in the physical properties and chemical composition of the materials, as well as factors such as the geometry and flow rate variations of the pipeline. Over time, these sediments accumulate, not only reducing the effective flow area of the pipeline, increasing fluid resistance, and decreasing delivery efficiency, but also causing residual sediments to mix with subsequent samples extracted through the delivery pipe when reacting and mixing other materials. This can affect the quality of subsequent samples, leading to misjudgments by operators and impacting the overall reaction and mixing process. Therefore, it is necessary to develop an improved enamel-lined reactor with convenient sampling capabilities to solve these problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a convenient enamel-lined reactor, comprising a reactor shell 1, a conveying pipe body 21, and a stirring mechanism. A support frame 4 is fixedly connected to the outside of the reactor shell 1. A heating wire body 5 is installed inside the reactor shell 1. A stirring mechanism is installed inside the reactor shell 1. The conveying pipe body 21 is fixedly connected inside the reactor shell 1. A first control valve body 22 and a second control valve body 220 are installed inside the conveying pipe body 21. A telescopic rod body 23 is fixedly connected to the outside of the conveying pipe body 21. A sliding frame 24 is fixedly connected to the right side of the telescopic rod body 23 and slidably connected to the conveying pipe. Inside the main body 21, a first motor 25 is fixedly connected to the right side of the sliding frame 24. A first rotating shaft 26 is fixedly connected to the output end of the first motor 25. The first rotating shaft 26 is rotatably connected inside the sliding frame 24. A cleaning brush body 27 is fixedly connected to the outside of the first rotating shaft 26. During use, reactants and other materials are poured into the reactor shell 1 through the feed inlet at the top of the reactor shell 1. The stirring mechanism then mixes the reactants. During mixing, the first control valve body 22 is opened, allowing the reactants inside to enter the conveying pipe body 21 for transport. After mixing is complete, the reactants are discharged through the discharge outlet at the bottom of the reactor shell 1. When deposits accumulate on the conveying pipe body 21, the second control valve body 220 is opened, and then the extension rod... The retraction of the main body 23 causes the sliding frame 24 to slide. When the sliding frame 24 slides, the first motor 25 drives the first rotating shaft 26 to rotate. When the first rotating shaft 26 rotates, the cleaning brush body 27 rotates to clean the inner wall of the conveying pipe body 21. The conveying pipe body 21 has a groove at the relative position of the sliding frame 24. The sliding frame 24 is slidably connected to the inside of the groove. The groove restricts the sliding of the sliding frame 24, allowing it to slide linearly inside the conveying pipe body 21 while preventing it from detaching from the conveying pipe body 21. A fixed bracket 28 is fixedly connected to the outside of the reactor shell 1. The fixed bracket 28 is equipped with a conveying pump body 29, which is fixedly connected to the bottom of the conveying pipe body 21. The fixed bracket 28 is internally fixedly connected to a fixed housing 210. A connecting pipe 211 is fixedly connected between the fixed housing 210 and the pump body 29. A pressing plate 212 is slidably connected to the outside of the fixed housing 210. A connecting rod 213 is fixedly connected to the bottom of the pressing plate 212. A fixing rod 215 is fixedly connected to the inside of the connecting rod 213. A sliding block 214 is slidably connected to the outside of the fixed housing 210. The fixing rod 215 is slidably connected inside the sliding block 214. A fixing plate 216 is fixedly connected to the outside of the fixed housing 210. A spring 217 is fixedly connected between the fixing plate 216 and the sliding block 214. A snap-fit block 218 is fixedly connected to the inside of the sliding block 214. A storage tube 219 is snap-fit connected to the outside of the snap-fit block 218.Spring 217 provides a pushing force to sliding block 214, making locking block 218 more securely engaged with storage tube 219, thereby restricting the position of storage tube 219. Sliding block 214 has a groove at a position relative to fixed rod 215, and sliding block 214 is slidably connected inside the groove. The groove restricts the sliding of fixed rod 215, preventing fixed rod 215 from disengaging from sliding block 214. Simultaneously, the cooperation between sliding block 214 and fixed rod 215 drives locking block 218 to engage and disengage with storage tube 219.
[0022] Please see Figure 2 , Figure 6 In this embodiment, preferably, the stirring mechanism includes a second motor 31, which is fixedly connected to the top of the reactor shell 1. A first gear 32 is fixedly connected to the output end of the second motor 31 and rotatably connected to the inside of the reactor shell 1. A rotating gear 33 meshes with the outside of the first gear 32 and is rotatably connected to the inside of the reactor shell 1. A scraper 34 is fixedly connected to the bottom of the rotating gear 33, and a second gear 35 meshes with the inside of the rotating gear 33. A second rotating shaft 36 is fixedly connected to the bottom of the second gear 35 and rotatably connected to the inside of the reactor shell 1. A stirring rod 37 is fixedly connected to the outside of the second rotating shaft 36. When the rotating gear 33 rotates, it drives the scraper 34 to contact the inner wall of the reactor shell 1, preventing reactants from adhering to the inner wall of the reactor shell 1. The formation of clumps can affect the normal operation of the reactor. A rotating groove is provided on the outer shell 1 of the reactor at a position relative to the rotating gear 33. The rotating gear 33 is rotatably connected inside the rotating groove. The rotating groove restricts the rotation of the rotating gear 33, preventing it from detaching from the outer shell 1 or tilting during rotation, thus affecting the tilting of the scraper 34. Three second gears 35 and three second rotating shafts 36 are provided. The three second gears 35 are symmetrically meshed inside the rotating gear 33, and the three second rotating shafts 36 are fixedly connected to the bottom of the three second gears 35. By providing three second gears 35 and two rotating shafts 36, the rotation of the rotating gear 33 drives the rotation of the three second gears 35, which in turn drives the rotation of the three second rotating shafts 36. The stirring rod 37 then stirs and mixes the mixture in the reactor, further improving the overall mixing efficiency.
[0023] During operation, reactants and other materials are poured into the reactor shell 1 through the feed inlet at the top of the reactor shell 1. The second motor 31 then operates, driving the first gear 32 to rotate. The first gear 32, in turn, drives the rotating gear 33 to rotate. The rotating gear 33, in conjunction with the second gear 35, drives the second rotating shaft 36 to rotate. The rotating shaft 36, in turn, drives the stirring rod 37 to mix the materials inside the reactor shell 1. During mixing, the heating element 5 operates to control the temperature inside the reactor shell 1, thereby improving the mixing efficiency. During mixing, the first control valve 22 is opened, allowing the reactants to enter the conveying pipe 21. The conveying pump 29 then operates, allowing the materials entering the conveying pipe 21 to pass through the connecting pipe 211 into the storage pipe 219. After extraction, the pressing plate 212 is pressed down, causing it to slide downwards. As the pressing plate 212 slides, it moves the connecting rod 213. When the connecting rod 213 moves, it drives the sliding block 214 to slide outward through the fixed rod 215. When the sliding block 214 slides, it drives the snap-fit block 218 to disengage from the storage tube 219, thereby taking out the storage tube 219. After the subsequent test is completed, the storage tube 219 is put back into the fixed shell 210. When the pressing plate 212 is released, the spring 217 provides a pushing force to the sliding block 214, pushing the sliding block 214 and the snap-fit block 218 to slide inward, so that the snap-fit block 218 is snapped back into the storage tube 219 and fixed. After the subsequent mixing is completed, the reactants are discharged through the discharge port at the bottom of the reactor shell 1. When the conveying pipe body 21 has attached substances, the second control valve body 220 is opened. When the telescopic rod body 23 retracts, it drives the sliding frame 24 to slide. When the sliding frame 24 slides, the first motor 25 works to drive the first rotating shaft 26 to rotate. When the first rotating shaft 26 rotates, the cleaning brush body 27 rotates to clean the inner wall of the conveying pipe body 21.
[0024] Through the above steps, when sediment forms inside the conveying pipe body 21, the first rotating shaft 26 drives the cleaning brush body 27 to clean it, so as to solve the problem that material sediment will appear inside the conveying pipe when the sample is directly extracted through the built-in conveying pipe, which affects the overall mixing reaction.
