Description

Technical Field

[0001] The utility model relates to the technical field of distillation tanks, in particular to a distillation tank body with a temperature control function. Background Art

[0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of each component in a mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire component unit operation process, which is a combination of two unit operations of evaporation and condensation. Compared with other separation means, such as extraction, filtration crystallization, etc., its advantage lies in that no other solvents outside the system components need to be used, thus ensuring that no new impurities are introduced.

[0003] The prior art (publication number: CN 220588963 U) discloses a filtration distillation tank for producing DMC, including a distillation tank body and a condensation plate. Two support plates are fixedly connected to the top of the distillation tank body.

An air outlet pipe is fixedly communicated with the top of the distillation tank body. A heater is fixedly connected to the inner bottom wall of the distillation tank body. A water inlet pipe is fixedly communicated with one side of the distillation tank body. A detachable filtration assembly is arranged on the water inlet pipe. A water collection tank is fixedly connected to one side of the right support plate.

[0004] Although the above patent can filter the sundries in the DMC solution, and is convenient for disassembling and assembling the filter screen box to clean the filtered sundries and the filter screen box, and is also convenient for regularly disassembling, cleaning, and replacing the condensation plate, it has the following drawbacks: after the distilled liquid decreases, the available internal volume inside the distillation tank becomes larger, the path of the steam inside the distillation tank becomes longer, increasing the residence time of the steam in the tank and delaying the discharge speed of the steam, affecting the distillation efficiency, and further improvement is needed. Therefore, a distillation tank body with a temperature control function is proposed. Summary of the Utility Model

Specific implementation mode

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention.

[0028] This embodiment proposes a distillation tank body with a temperature control function, as Figures 1 to 5 shown, including a tank body 1. An observation window 5 for observing the interior is provided on the front part of the outer surface of the tank body 1. The left part of the upper end of the tank body 1 is inserted and connected with an ultrasonic liquid level sensor 6. The front part of the upper end of the tank body 1 is inserted and connected with a feed pipe 18. Open the lid on the feed pipe 18 and pour the liquid to be distilled into the tank body 1. The liquid level height of the liquid can be measured by the ultrasonic liquid level sensor 6. The right part of the upper end of the tank body 1 is inserted and connected with an exhaust pipe 7. A heating disk 13 is installed on the upper end of the movable disk 11. Turn on the power supply of the heating disk 13 to heat the liquid in the tank body 1 to a certain temperature to form water vapor, and then discharge it through the exhaust pipe 7. However, after the distilled liquid decreases, the available internal volume inside the tank body 1 becomes larger, the path of the steam inside the tank body 1 becomes longer, the residence time of the steam in the tank body 1 increases, the discharge speed of the steam is delayed, and the distillation efficiency is affected.

[0029] To improve the above situation, a movable disk 11 that can move up and down is provided on the inner cylindrical surface of the tank body 1. The movable movable disk 11 can adjust the volume of the available space inside the tank body 1. As the distillation operation progresses, the movable disk 11 moves upward, the volume of the available space inside the tank body 1 decreases, the path of the steam inside the tank body 1 becomes smaller, the residence time of the steam in the tank body 1 is reduced, the discharge speed of the steam is accelerated, and the distillation efficiency is improved.

[0030] By installing a driving component 10 at the lower end of the tank body 1, the driving component 10 can automatically drive the movable disk 11 to move up and down. Specifically, the driving component 10 includes a bearing seat 101, and the bearing seat 101 is provided with two symmetrically distributed left and right. The two bearing seats 101 are both installed at the lower end of the tank body 1. A rotatable worm 102 is commonly provided between the two bearing seats 101. The worm 102 is meshedly connected with two worm wheels 103 distributed left and right. The interiors of the two worm wheels 103 are both threadedly sleeved with screw rods 104. The upper ends of the two worm wheels 103 are rotatably connected to a first rotating platform 105. The first rotating platform 105 is used to support the rotation of the worm wheel 103. The upper ends of the two screw rods 104 move through the first rotating platform in turn. The upper end of the movable platform 105 is fixedly connected to the lower wall of the tank body 1 and the lower end of the movable disk 11. The upper ends of the two first rotating platforms 105 are fixedly connected to the lower end of the tank body 1. The right end of the worm 102 moves through the right bearing seat 101 and is connected to the first motor installed at the lower end of the tank body 1. When in use, when the ultrasonic liquid level sensor 6 detects that the liquid inside the tank body 1 is reduced, the first motor is controlled by the controller 4 to drive the worm 102 to rotate, and the worm 102 drives the worm wheel 103 to rotate. The worm wheel 103 drives the screw rod 104 to move upward through its own rotation, and the screw rod 104 drives the movable disk 11 to move upward, and the movable disk 11 drives the liquid to move upward, so that the volume of the available space inside the tank body 1 is reduced.

[0031] In addition, when the movable disk 11 moves up and down, the liquid may flow to the bottom wall of the tank body 1 through the gap between the movable disk 11 and the inner wall of the tank body 1. It is necessary to improve the sealing between the movable disk 11 and the inner wall of the tank body 1. In order to achieve the purpose of sealing, a groove 1101 is provided on the outer cylindrical surface of the movable disk 11. A sealing ring 1102 is arranged inside the groove 1101. The sealing ring 1102 is in active contact with the inner wall surface of the tank body 1. The sealing ring 1102 can be elastically deformed and squeezed to fill the gap between the movable disk 11 and the inner wall of the tank body 1 and reduce the risk of leakage.

[0032] A temperature sensor 14 is installed at the upper right part of the movable plate 11, and the temperature of the liquid inside the tank body 1 can be measured by the temperature sensor 14, so as to facilitate the subsequent adjustment of the temperature of the heating plate 13 by the controller 4 to realize the temperature control function.

[0033] When the distilled raw liquid is poured into the tank body 1, in order to promote the diffusion and transfer of liquid molecules in the mixture and make it easier for the liquid molecules to evaporate from the liquid phase, it is necessary to improve the mixing effect by stirring. For this purpose, the middle part of the upper end of the movable disk 11 is rotatably connected to a second rotating table 121, and a rotatable connecting rod 15 is arranged inside the second rotating table 121. The outer surface of the connecting rod 15 is provided with a stirring blade 12 through a movable sleeve of the protrusion 151. The protrusion 151 can facilitate the connecting rod 15 to drive the stirring blade 12 to rotate while The stirring blade 12 can move up and down with the movable disk 11, and the lower end of the stirring blade 12 is fixedly connected to the upper end of the second rotating platform 121. The second rotating platform 121 is used to support the stirring blade 12 to rotate and drive it to move; the lower end of the connecting rod 15 movably passes through the lower end of the movable disk 11 and is movably connected to the bottom wall of the tank body 1, and the upper end of the connecting rod 15 movably passes through the upper end of the tank body 1 and is transmission-connected to the second motor installed at the upper end of the tank body 1. When in use, the second motor is controlled to drive the connecting rod 15 to rotate, and the connecting rod 15 drives the stirring blade 12 to stir the liquid to accelerate the mixing between different liquids.

[0034] When the movable disk 11 moves up and down, the depth of the liquid in the tank body 1 changes, resulting in the ultrasonic liquid level sensor 6 being unable to calculate the specific value of the liquid level through the difference. For this reason, four support seats 3 distributed in a rectangular array are installed at the lower end of the tank body 1, and a horizontal plate 16 is installed at the front end of the rear left support seat 3. A pull-wire displacement sensor 17 is installed at the upper end of the horizontal plate 16. The measuring end of the pull-wire displacement sensor 17 is fixedly connected to the lower end of the screw rod 104. When the screw rod 104 moves, the pull wire inside the pull-wire displacement sensor 17 is driven to move upward. The pull-wire displacement sensor 17 measures the moving distance of the screw rod 104. The height of the available volume inside the tank body 1 is subtracted from the moving distance of the screw rod 104 from the overall height of the internal volume of the tank body 1. The height of the overall liquid can be obtained by subtracting the value of the distance from the liquid surface measured by the ultrasonic liquid level sensor 6 from the height of the available volume.

[0035] A valve tube 2 is inserted and connected to the lower left part of the outer surface of the tank body 1, and a controller 4 is installed on the front of the outer surface of the tank body 1. The valve tube 2 can be opened to discharge the remaining liquid inside.

[0036] In addition, the exhaust pipe 7 is connected to the condenser 8, which is provided with a water inlet and a drain outlet. When steam is poured into the condenser 8, condensed water is poured into the condenser 8 through the water inlet to condense the internal steam. The lower side of the condenser 8 is connected to the collecting tank 9, so that the steam condenses and enters the collecting tank 9.
