DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5The utility model provides a technical solution: a synthesis device of choline chloride ionic liquid, comprising a reaction tank 1 and a raw material box 2, the top of the reaction tank 1 is connected to three raw material boxes 2, and the raw material box 2 extends to the inside of the reaction tank 1, the top of the reaction tank 1 is installed with an upper baffle 3, the top of the reaction tank 1 is installed with a motor 4, and the motor 4 is connected to a stirring shaft a7, the stirring shaft a7 is connected to a gear rack 5, and the side of the gear rack 5 is connected to the bevel gear a6, and the gear rack 5 is fixedly installed on the top of the upper baffle 3, and the stirring shaft a7 is connected to the stirring shaft b8 , and the stirring shaft b8 is also connected to the gear frame 5, the top of the stirring shaft b8 is connected to the bevel gear a6, and the bevel gear a6 is also connected to the stirring shaft a7, an air pipe 9 is arranged on the side of the reaction tank 1, and one end of the air pipe 9 is connected to the air storage tank 10, and the air pipe 9 is connected to the interior of the reaction tank 1, a water pipe 12 is arranged on the side of the reaction tank 1, and the water pipe 12 is connected to the water tank 14 through a water pump 13, and the water pipe 12 is connected to the interior of the channel reaction tank 1, the bottom end of the reaction tank 1 is connected to the collecting box 11 through a collecting pipe 15, and the collecting pipe 15 is connected to the interior of the channel reaction tank 1.

[0025] The utility model provides a synthesis device for choline chloride ionic liquid. When synthesizing the ionic solution, firstly, the raw materials to be reacted are added into the reaction tank 1 through the raw material box 2, and then the motor 4 is determined to drive the stirring shaft a7 to rotate. When the stirring shaft a7 rotates, the beveled teeth b701 set at the top of the stirring shaft a7 will drive the beveled teeth a6 meshed with the side to rotate, and the beveled teeth a6 will drive the beveled teeth c801 meshed with the side to rotate. After the transmission, the rotation direction of the stirring shaft a7 is opposite to the rotation direction of the stirring shaft b8, so that the rotation speed of the stirring blade a702 is consistent with that of the stirring blade b803, but the rotation direction is opposite. Through the two different rotation directions, the opposite rotation direction is achieved. The raw materials in the reaction tank 1 can be fully stirred, and the heating layer in the inner wall of the reaction tank 1 can be turned on during the stirring process, so as to improve the efficiency of the reaction. When gas is generated due to the chemical reaction inside, the pressure sensor arranged on the upper baffle plate 3 will monitor the pressure of the reaction tank 1. When the pressure is too high, the upper baffle plate 3 will control the valve in the air pipe 9 to open, so that the excess gas can enter the gas storage tank 10 through the air pipe 9. When the synthesis of the ion solution is completed, the finished product will flow from the collection pipe 15 into the collection box 11. The operator can transport water to the reaction tank 1 through the water pump 13, and drive the rotating blades to rotate by starting the motor 4, so as to perform a cleaning operation on the reaction tank 1.

[0026] Specifically, the reaction tank 1 has a metal body, and a heating layer is provided in the inner interlayer thereof, which is beneficial for heating the liquid inside the reaction tank 1, thereby improving the efficiency of some reactions.

[0027] Specifically, the material pipe arranged at the bottom end of the raw material box 2 is connected to the interior of the reaction tank 1 , which is conducive to adding reaction raw materials into the interior of the reaction tank 1 through the raw material box 2 .

[0028] Specifically, a pressure sensor is provided inside the upper baffle plate 3 and is connected to the valve inside the front end of the air pipe 9, which is beneficial for the pressure sensor to monitor the pressure of the reaction tank 1. When the pressure is too high, the upper baffle plate 3 will control the valve inside the air pipe 9 to open, so that excess gas can enter the gas storage tank 10 through the air pipe 9.

[0029] Specifically, the gear rack 5 and the bevel gear a6, the stirring shaft a7, and the stirring shaft b8 all constitute a rotating structure, and the bevel gear a6 and the bevel gear b701 set on the top of the stirring shaft a7 and the bevel gear c801 set on the top of the stirring shaft b8 all constitute a gear meshing face structure, and the stirring shaft a7 also passes through the rotating groove 802 set in the center of the stirring shaft b8 to form a rotating structure with it, which is beneficial to the fact that when the stirring shaft a7 rotates, the bevel gear b701 set on the top will drive the bevel gear a6 meshed with it on the side to rotate, and the bevel gear a6 will drive the bevel gear c801 meshed with it to rotate, and after transmission, the rotation direction of the stirring shaft a7 is opposite to that of the stirring shaft b8, so that the rotation speed of the stirring blade a702 and the stirring blade b803 are consistent but the rotation direction is opposite.

[0030] Specifically, the stirring blade a702 set at the bottom end of the stirring shaft a7 and the stirring blade b803 set at the bottom end of the stirring shaft b8 are designed to be mirror-symmetrical, which is beneficial.

[0031] Specifically, controllable valves are installed inside the air pipe 9, the water pipe 12 and the collecting pipe 15, which is helpful to ensure that the liquid inside the reaction tank 1 will not flow back into the gas storage tank 10, the collecting box 11 and the water tank 14 during the reaction.
