Description

Technical Field

[0001] This utility model relates to the field of condensation kettle technology, and in particular to a temperature control device for condensation kettle. Background Technology

[0002] Condensation is a very important class of organic reactions, widely used in organic synthesis. It is a crucial method for synthesizing larger organic compounds from smaller molecules and is typically carried out in a condensation reactor. To facilitate timely monitoring of the temperature during the condensation reaction, a temperature sensor is usually installed inside the condensation reactor.

[0003] However, the temperature control devices for condensation kettles in related technologies still have shortcomings. The temperature control sensor in the temperature control device is fixed inside the condensation kettle, which is inconvenient to extend, retract, or shake. This makes it easy for the compound in the condensation kettle to adhere to the outside of the sensor head, resulting in inaccurate temperature readings when measuring the temperature inside the condensation kettle. Furthermore, it is inconvenient to disassemble, repair, and maintain the temperature control sensor after long-term use. Therefore, we propose a temperature control device for condensation kettles to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a temperature control device for a condensation vessel, which features a temperature sensor that can be easily extended and shaken, making it less likely for compounds in the condensation vessel to adhere to the outside of the sensor's sensing head, thus improving the accuracy of temperature measurement. Furthermore, the temperature sensor can be easily and efficiently disassembled and reassembled, facilitating regular inspection and maintenance.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a temperature control device for a condensation vessel, comprising a condensation vessel body, a temperature control mechanism provided on the condensation vessel body, the temperature control mechanism including a heating ring fixedly sleeved on the outside of the condensation vessel body, a temperature control sensor provided on the condensation vessel body, a controller fixedly connected to the top of the condensation vessel body, the temperature control sensor and the heating ring being electrically connected to the controller, a stirring motor fixedly connected to the top of the condensation vessel body, a stirring shaft fixedly connected to the output shaft of the stirring motor, multiple stirring rods fixedly connected to the outside of the stirring shaft, a cylinder fixedly connected to the top of the condensation vessel body, a top plate fixedly connected to the output shaft of the cylinder, a lifting plate provided below the top plate, a telescopic swaying mechanism provided between the lifting plate and the top plate, and a disassembly and maintenance mechanism provided between the lifting plate and the temperature control sensor.

[0006] A further feature of this invention is that a counterweight is fixedly connected to one side of the top plate, and the same telescopic rod is fixedly connected between the condensation vessel body and the top plate.

[0007] By adopting the above technical solution, it is convenient to guide the top plate, while ensuring that the weight on both sides of the cylinder is balanced.

[0008] A further feature of this invention is that the telescopic swaying mechanism includes a drive motor fixedly connected to the top of the top plate and a worm gear rotatably connected to the bottom of the top plate. A worm is fixedly connected to the output shaft of the drive motor, and the worm meshes with the worm gear. A drive rod is fixedly connected to the front side of the worm gear. A movable frame is slidably sleeved on the outer side of the drive rod. A connecting plate is fixedly connected to the bottom of the movable frame. A lifting plate is fixedly connected to the bottom of the connecting plate. A limiting hole is opened at the top of the condensing vessel. A guide ring and a rubber wiping ring are fixedly connected sequentially from top to bottom in the limiting hole. The sensing head of the temperature control sensor is slidably sleeved in the guide ring and the rubber wiping ring.

[0009] By adopting the above technical solution, in order to avoid the situation where the compound adheres to the sensing head of the temperature control sensor and causes inaccurate temperature measurement, the drive motor is started. The drive motor drives the worm gear to rotate, and the worm gear drives the worm wheel and drive rod to rotate. The drive rod slides in the moving frame and drives the connecting plate, lifting plate and temperature control sensor to reciprocate up and down. During the up and down shaking process, the compound in the condensation vessel is prevented from adhering to the sensing head. At the same time, under the up and down movement, the sensing head slides in the rubber wiping ring (made of high temperature resistant rubber) and guide ring, thereby wiping off the compound adhering to the sensing head and letting it fall back into the condensation vessel.

[0010] A further feature of this invention is that a guide rod is fixedly connected to the top of the condensation vessel, and the lifting plate is slidably sleeved on the outside of the guide rod.

[0011] By adopting the above technical solution, it is easier to guide the lifting platform, making its lifting and lowering more stable and smooth.

[0012] A further feature of this invention is that a stabilizing plate is fixedly connected to the bottom of the top plate, and the worm gear is rotatably connected to the front side of the stabilizing plate.

[0013] By adopting the above technical solution, it is convenient to support the worm gear, making its rotation more stable.

[0014] A further feature of this invention is that the disassembly and maintenance mechanism includes a mounting plate fixedly connected to the top of the temperature control sensor and a fixing sleeve fixedly connected to the top of the lifting plate. Two plug-in plates are fixedly connected to the top of the mounting plate. A locking hole is provided on one side of each plug-in plate. Springs are fixedly connected to the sides of the two fixing sleeves that are close to each other. A horizontal sliding plate is fixedly connected to the ends of the two springs that are close to each other. A locking rod is fixedly connected to the outer side of each horizontal sliding plate. The two locking rods are movably locked into corresponding locking holes. Movable rods are rotatably connected to the sides of the two horizontal sliding plates that are close to each other. The top ends of the two movable rods are rotatably connected to the same pull plate. The pull plate is slidably sleeved on the outer side of the connecting plate. Two through slots are provided on the top of the lifting plate. The two plug-in plates are movably inserted into the corresponding through slots and fixing sleeves.

[0015] By adopting the above technical solution, when the temperature control sensor needs to be disassembled and maintained after long-term use, the cylinder is activated, which moves the top plate upward, thereby pulling out the sensing head of the temperature control sensor completely for disassembly. Pulling the pull plate upward moves the two movable rods upward, which in turn move the two transverse plates and locking rods inward and disengage them from the locking holes, thus removing the plug plate. At this point, the plug plate, mounting plate, and temperature control sensor can be disassembled together for maintenance. After maintenance, the plug plate is inserted into the through slot and fixing sleeve, and the pull plate is released. Under the elastic force of the spring, the two locking rods move away from each other and lock into their corresponding locking holes, thus fixing the temperature control sensor to the bottom of the lifting plate. Finally, the cylinder is activated in reverse, causing the lifting plate and temperature control sensor to move downward, and the sensing head of the temperature control sensor is inserted into the guide ring and rubber wiping ring.

[0016] A further feature of this invention is that the top of the lifting plate has two grooves, two transverse plates are slidably fitted into the corresponding grooves, and two springs are respectively fitted onto the outer side of the corresponding levers.

[0017] By adopting the above technical solution, it is convenient to guide the spring and the transverse plate, making their movement more stable.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model uses a temperature control sensor to measure the temperature inside the condensation vessel and a heating ring to heat the condensation vessel. When the temperature reaches the required level, the temperature control sensor sends a signal to the controller, which then turns off the heating ring. When the temperature drops below the set value, the heating ring is turned on again to heat the vessel, thereby controlling the temperature inside the condensation vessel within a specified range.

[0020] 2. This utility model uses a drive motor to rotate a worm gear, which in turn drives the worm wheel and drive rod to rotate. The drive rod slides within the moving frame and drives the connecting plate, lifting plate, and temperature control sensor to reciprocate up and down. During the up and down movement, the compound inside the condensation vessel is prevented from adhering to the sensing head. At the same time, during the up and down movement, the sensing head slides within the rubber wiping ring and guide ring, thereby wiping away the compound adhering to the sensing head and causing it to fall back into the condensation vessel.

[0021] 3. This utility model uses a cylinder to move the top plate upwards, which can completely pull out the sensing head of the temperature control sensor for disassembly. Pulling the pull plate upwards causes the two movable rods to move upwards, which in turn cause the two horizontal sliding plates and locking rods to move inwards and disengage from the locking holes, thus preventing the plug-in plate from being fixed. At this point, the plug-in plate, mounting plate, and temperature control sensor can be disassembled together for maintenance. After maintenance, the plug-in plate is inserted into the through slot and fixing sleeve, and the pull plate is released. At this time, under the elastic force of the spring, the two locking rods move away from each other and are respectively locked into the corresponding locking holes, thus fixing the temperature control sensor to the bottom of the lifting plate. Finally, the cylinder is activated in reverse, causing the lifting plate and temperature control sensor to move downwards, and the sensing head of the temperature control sensor is inserted into the guide ring and rubber wiping ring.

[0034] Specifically, a stabilizing plate is fixedly connected to the bottom of the top plate 13, and a worm gear 74 is rotatably connected to the front side of the stabilizing plate.

[0035] Specifically, refer to Figures 1-4 The disassembly and maintenance mechanism 8 includes a mounting plate 83 fixedly connected to the top of the temperature control sensor 5 and a fixing sleeve 87 fixedly connected to the top of the lifting plate 6. Two plug-in plates 85 are fixedly connected to the top of the mounting plate 83. A locking hole 88 is opened on one side of the plug-in plate 85. A spring 89 is fixedly connected to the side of the two fixing sleeves 87 that are close to each other.

[0039] In this invention, the temperature inside the condensation vessel 1 can be measured by the temperature control sensor 5, and the condensation vessel 1 can be heated by the heating ring 2. When the required temperature is reached, the temperature control sensor 5 sends a signal to the controller 3, and the controller 3 closes the heating ring 2. When the temperature is lower than the set value, the heating ring 2 is reopened for heating, thus controlling the temperature inside the condensation vessel 1 within a specified range. To prevent compounds from adhering to the sensing head of the temperature control sensor 5 and causing inaccurate temperature measurements, the drive motor 71 is activated. The drive motor 71 drives the rotation of the worm gear 72, which in turn drives the rotation of the worm wheel 74 and the drive rod 75. The drive rod 75 slides within the moving frame 73 and drives the connecting plate 76, the lifting plate 6, and the temperature control sensor 5 to reciprocate up and down. During the up and down movement, the compounds inside the condensation vessel 1 are prevented from adhering to the sensing head. At the same time, during the up and down movement, the sensing head slides within the rubber wiping ring 78 (made of high-temperature resistant rubber) and the guide ring 77, thereby wiping away the compounds adhering to the sensing head. Wipe it off and let it fall back into the condensation vessel 1. When the temperature control sensor 5 needs to be disassembled and maintained after long-term use, start the cylinder 11. The cylinder 11 moves the top plate 13 upward, which can then pull out the sensing head of the temperature control sensor 5 completely for disassembly. Pull the pull plate 81 upward, which moves the two movable rods 82 upward. The two movable rods 82 move the two transverse plates 84 and the locking rod 86 inward and disengage from the locking hole 88, thus not fixing the plug plate 85. At this time, the plug plate 85 can be removed. 5. The mounting plate 83 and the temperature control sensor 5 are removed together for maintenance. After maintenance, the plug plate 85 is inserted into the through slot and the fixing sleeve 87, and the pull plate 81 is released. At this time, under the elastic force of the spring 89, the two locking rods 86 move away from each other and are respectively locked into the corresponding locking holes 88, thereby fixing the temperature control sensor 5 to the bottom of the lifting plate 6. Finally, the cylinder 11 is reversed to move the lifting plate 6 and the temperature control sensor 5 down, and the sensing head of the temperature control sensor 5 is inserted into the guide ring 77 and the rubber wiping ring 78.
