Description

Technical Field

[0001] This utility model belongs to the field of distillation equipment technology, specifically a toluene distillation apparatus. Background Technology

[0002] In the preparation of toluene, purification is required through a distillation apparatus. During toluene distillation, the raw material is usually heated directly by a heating plate, resulting in uneven heating of the material in different areas of the distillation vessel. This not only affects the efficiency of toluene distillation but may also cause differences in product quality. In addition, after use, residual toluene and other impurities will adhere to the inner wall of the distillation vessel, forming dirt. This dirt will not only affect the heat transfer efficiency of the distillation vessel but also affect the purity of the subsequently distilled product. Traditional methods of cleaning the inner wall mostly involve manual cleaning at regular intervals, which is cumbersome and the cleaning effect is difficult to guarantee.

[0003] Therefore, a toluene distillation apparatus is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a toluene distillation apparatus that solves the problems of uneven material stirring, uneven heating, and difficulty in cleaning the inner wall of the toluene distillation vessel in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toluene distillation apparatus, comprising a distillation kettle, a top cover installed at the top of the distillation kettle, a cooling pipe installed on one side of the upper surface of the top cover, a stirring mechanism provided on the surface of the top cover, the stirring mechanism including a transmission rod rotating inside the top cover, a motor installed on the upper surface of the top cover, and the output end of the motor connected to the transmission rod, a stirring rod fixedly connected to the bottom end of the transmission rod, a cleaning mechanism provided on the surface of the transmission rod, the cleaning mechanism including a fixing rod symmetrically fixedly connected to the top end of the surface of the transmission rod, a storage box fixedly connected to the side of the fixing rod, a fixing box hinged inside the storage box, a rotating shaft rotatably connected inside the fixing box, and a cleaning rod provided at the bottom end of the rotating shaft.

[0006] Preferably, the sweeping rod is connected to the outer end of the rotating shaft by bolts.

[0008] Preferably, a connecting rod is hinged to the side of the fixing box, and a first electric push rod is installed inside the storage box, with the output end of the first electric push rod hinged to the connecting rod.

[0009] Preferably, the storage box has a lid that is slidably connected to its interior, with one end of the lid located on the outside of the storage box. A second electric push rod is installed inside the storage box near the lid, and the output end of the second electric push rod is connected to the outer end of the lid.

[0010] Preferably, a first gear is rotatably connected inside the storage box, and one end of the first gear is connected to the rotating shaft. A second gear is meshed with the surface of the first gear, and a roller is connected to the upper side of the second gear through a connecting shaft, with one end of the roller located on the outside of the storage box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model incorporates a stirring mechanism. By starting a motor and driving a transmission rod to rotate, the stirring rod can stir the inside of the distillation vessel, ensuring that the material inside the distillation vessel is heated fully and evenly.

[0013] 2. This utility model incorporates a cleaning mechanism.

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

[0020] like Figures 1 to 4 As shown, this utility model provides a toluene distillation apparatus, including a distillation kettle 1. A top cover 4 is installed at the top of the distillation kettle 1. A cooling pipe 5 is installed on one side of the upper surface of the top cover 4. A stirring mechanism 2 is provided on the surface of the top cover 4. The stirring mechanism 2 includes a transmission rod 23 rotating inside the top cover 4. A motor 21 is installed on the upper surface of the top cover 4, and the output end of the motor 21 is connected to the transmission rod 23. A stirring rod 22 is fixedly connected to the bottom end of the transmission rod 23. A cleaning mechanism 3 is provided on the surface of the transmission rod 23. The cleaning mechanism 3 includes a fixing rod 31 symmetrically fixedly connected to the top of the surface of the transmission rod 23. A storage box 32 is fixedly connected to the side of the fixing rod 31. A fixing box 35 is hinged inside the storage box 32. A rotating shaft 39 is rotatably connected inside the fixing box 35. A cleaning rod 33 is provided at the bottom of the rotating shaft 39. During the distillation of p-toluene, the transmission rod 23 is driven to rotate by the starting motor 21, which can stir the inside of the distillation vessel 1 through the stirring rod 22 to ensure that the material inside the distillation vessel 1 is heated fully and evenly. When it is necessary to clean the inside of the distillation vessel 1 after distillation, the connecting rod 36 is moved by starting the first electric push rod 34, which pushes the fixed box 35 to flip, so that the cleaning rod 33 is pressed against the inner wall of the distillation vessel 1. Then, the starting motor 21 drives the cleaning rod 33 to rotate through the fixed rod 31 to clean the inner wall of the distillation vessel 1. This can achieve efficient and comprehensive cleaning of the inner wall of the distillation vessel 1. Compared with the traditional manual cleaning method, it greatly reduces the labor intensity and improves the cleaning efficiency and effect.

[0021] like Figures 1 to 4 As shown, the sweeping rod 33 is connected to the outer end of the rotating shaft 39 by bolts, which allows the sweeping rod 33 to be disassembled, improving the convenience of cleaning and replacing the sweeping rod 33.

[0022] The interior of the distillation vessel 1 is equipped with a spiral heating tube 24, which improves the heating effect of the heating tube 24 on the interior of the distillation vessel 1.

[0023] like Figures 1 to 4As shown, a connecting rod 36 is hinged to the side of the fixed box 35. A first electric push rod 34 is installed inside the storage box 32, and the output end of the first electric push rod 34 is hinged to the connecting rod 36. A box cover 38 is slidably connected inside the storage box 32, and one end of the box cover 38 is located on the outside of the storage box 32. A second electric push rod 37 is installed inside the storage box 32 near the box cover 38, and the output end of the second electric push rod 37 is connected to the outer end of the box cover 38. By activating the connecting rod 36, the cleaning rod 33 can be pushed to flip over, so that the cleaning rod 33 can be stored inside the storage box 32 when cleaning is not required. At the same time, activating the second electric push rod 37 can drive the box cover 38 to seal the storage box 32, isolate and protect the cleaning rod 33, and improve the service life of the cleaning rod 33.

[0024] The storage box 32 is rotatably connected to a first gear 310, and one end of the first gear 310 is connected to a rotating shaft 39. The surface of the first gear 310 is meshed with a second gear 311. The upper side of the second gear 311 is connected to a roller 312 through a connecting shaft, and one end of the roller 312 is located on the outside of the storage box 32. When the cleaning rod 33 cleans the inner wall of the distillation vessel 1, the roller 312 will stick to the inner wall of the distillation vessel 1. During the rotation of the cleaning rod 33 driven by the fixed rod 31, the roller 312 will roll on the inner wall of the distillation vessel 1. The cleaning rod 33 is driven to rotate by the transmission of the second gear 311 and the first gear 310, which further improves the cleaning effect of the cleaning rod 33 on the inner wall of the distillation vessel 1.

[0025] Working principle and process: During the distillation of p-toluene, the motor 21 drives the transmission rod 23 to rotate, which in turn stirs the inside of the distillation vessel 1 through the stirring rod 22, ensuring that the material inside the distillation vessel 1 is heated evenly. When it is necessary to clean the inside of the distillation vessel 1 after distillation, the second electric push rod 37 is activated to open the box cover 38, and then the first electric push rod 34 is activated to move the connecting rod 36 and push the fixed box 35 to flip, so that the cleaning rod 33 is pressed against the inner wall of the distillation vessel 1. Then, the motor 21 drives the cleaning rod 33 to rotate through the fixed rod 31, cleaning the inner wall of the distillation vessel 1. During this period, the roller 312 rolls on the inner wall of the distillation vessel 1, and the second gear 311 and the first gear 310 drive the cleaning rod 33 to rotate, further improving the cleaning effect of the cleaning rod 33 on the inner wall of the distillation vessel 1, achieving efficient and comprehensive cleaning of the inner wall of the distillation vessel 1. Compared with the traditional manual cleaning method, it greatly reduces the labor intensity and improves the cleaning efficiency and effect.
