Description

Technical Field

[0001] The utility model relates to the technical field of distillation machines, in particular to a distillation machine for acetophenone with high safety. Background Art

[0002] The acetophenone distillation machine is a device used to separate and purify acetophenone from other substances. The acetophenone distillation machine uses the difference in boiling points of different components (acetophenone and other impurities) to separate acetophenone from the mixture through the process of heating, evaporation, cooling and condensation. Usually, continuous distillation is used to heat the solution or mixture to the boiling point of acetophenone, evaporate it into steam, and then quickly condense the steam into liquid through a cooling system, and finally collect the separated acetophenone. Among them, acetophenone is volatile and flammable, so when using the distillation machine, you must be extra careful and follow the relevant safety regulations to ensure the safety and reliability of the operation; combined with the existing literature High-efficiency rotary distillation machine (CN210495291U)

[0003] The existing technology has the following problems:

[0004] 1. Existing acetophenone distillation machines. Since acetophenone is a flammable substance, acetophenone and other liquids may generate static electricity accumulation during the distillation process. Static electricity accumulation may lead to fire or explosion risks, especially when operating around flammable materials. Static electricity accumulation may accumulate during operation or inside the equipment. Under certain conditions, it may cause sparks or flames, resulting in fire or explosion.

[0005] 2. When discharging waste liquid from the existing acetophenone distillation machine, manual discharge of waste may involve contact with the waste, increasing the risk of operators being exposed to hazardous substances, especially when handling toxic, flammable or corrosive wastes. Manual discharge of waste requires additional manpower and time, and may increase the complexity of the operation.

[0006] To this end, we proposed a highly safe acetophenone distillation machine to solve the above-mentioned drawbacks. Utility Model Content

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0031] Example: Figure 1 and 1 Figure 3As shown, a highly safe acetophenone distillation machine includes a specific model of a liquid extraction pump used in the machine, which is Waters 515HPLC Pump. This model has the advantages of low noise, high sensitivity, and a wide linear range. A heating plate 12 is arranged above the base 1, and a micro circular groove is arranged in the center of the heating plate 12 for placing a distillation flask 3. Then, a temperature sensor 9 at the end of a connecting line extending from one side of the base 1 is inserted into the distillation flask 3. A support rod 16 is installed at one corner of the base 1. The support rod 16 is connected to a connecting rod through a hinge sleeve. The temperature sensor 9 penetrates the top of the connecting rod to ensure the stability of the temperature sensor 9 in the distillation flask 3. Then, the cover 21 is opened, and the acetophenone mixture is poured into the distillation flask 3 through the liquid inlet 15. The cover 21 is closed with the liquid inlet 15, and then the heating plate 12 is heated to a temperature reaching the vaporization point of the acetophenone. At the same time, the temperature does not exceed the vaporization point of other mixtures, and its temperature data is uploaded to the control panel 2 through the temperature sensor 9. The temperature degree can be adjusted through the control panel 2, and then the acetophenone vapor floats upward, and is guided to the transmission pipe 4 by the guide rods 17 equidistantly installed above the inner wall of the distillation flask 3, and then floats into the condenser 5. When the vapor passes through the condenser 5, the temperature of the tube wall is lower than the temperature of the vapor, so that the heat in the vapor can be transferred to the surface of the condenser 5. As the heat is lost, the molecules in the vapor gradually lose energy and condense into liquid. Then, a liquid pump 7 is connected to the surface of the liquid extraction pipe 6 at the output end of the condenser 5, and the condensed acetophenone liquid can be transported to the collecting bottle 8 through the liquid extraction pipe 6.

[0032] like Figure 2 As shown, when the pure acetophenone in the distillation flask 3 is collected by the collecting bottle, the remaining mixture is useless and does not need to be left in the distillation flask 3, then the second liquid extraction tube 13 is inserted into the distillation flask 3 and extended to the bottom, and at the same time, a second liquid extraction pump is arranged above the extended connecting plate of the base 1, which is penetrated by the second liquid extraction tube 13, and the other end of the second liquid extraction tube 13 is extended into the waste liquid bottle 14 through the inlet above the waste liquid bottle 14, so that the waste liquid in the distillation flask 3 is extracted and discharged into the waste liquid bottle 14 at the end of the second liquid extraction tube 13.

[0033] like Figure 4As shown, without a static dissipator, static electricity may accumulate during operation or inside the equipment. Under certain conditions, such as the triggering of static discharge or corona discharge, sparks or flames may be caused, resulting in fire or explosion. The static dissipator 11 is fixed to the outer wall surface of the distillation flask 3 through two connecting plates, and metal rings 18 are installed equidistantly above the static dissipator 11. The metal ring 18 transfers the collected charge ions to the metal block 20 through a conductive tube 19 connected to the metal ring 18. The conductive property of the metal block 20 is used to guide and dissipate the electrostatic charge, thereby quickly and effectively dissipating static electricity and reducing the risk of static electricity accumulation.

[0034] Working principle: personnel insert the temperature sensor 9 at the end of the connecting line extending from one side of the base 1 into the distillation flask 3 and then open the cover 21, pour the acetophenone mixture into the distillation flask 3 through the liquid inlet 15, close the liquid inlet 15 with the cover 21, and then heat the heating plate 12 to make its temperature reach the vaporization point of acetophenone. The temperature degree can be adjusted through the control panel 2, and then the acetophenone vapor floats upward, and is guided to the transmission pipe 4 by the guide rods 17 installed equidistantly above the inner wall of the distillation flask 3, and then floats into the condenser 5. As the heat is lost, the molecules in the vapor gradually lose energy and condense into liquid, and then a pumping tube 6 at the output end of the condenser 5 is sleeved on the surface. Liquid pump 17 can transport the condensed acetophenone liquid to the collecting bottle 8 through the liquid extraction tube 16. When the pure acetophenone in the distillation flask 3 is collected by the collecting bottle, the liquid extraction tube 2 13 is inserted into the distillation flask 3 and extended to the bottom. The other end of the liquid extraction tube 2 13 extends into the waste liquid bottle 14 through the inlet above the waste liquid bottle 14. Therefore, the waste liquid in the distillation flask 3 is extracted and discharged into the waste liquid bottle 14 at the end of the liquid extraction tube 2 13. The static dissipator 11 is fixed to the outer wall surface of the distillation flask 3 through two connecting plates. The metal ring 18 transmits the collected charge ions to the metal block 20 through the conductive tube 19 connected to the metal ring 18, and the conductive property of the metal block 20 is used to guide and dissipate the electrostatic charge.

[0035] In this embodiment: the control circuit of the control panel 2 can be realized by simple programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0036] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
