[0027] 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.

[0028] See Figures 1-5 This utility model provides the following two technical solutions:

[0029] The first embodiment provides a dehydration and deacidification device for chloroethylene carbonate, comprising:

[0030] Acid removal box 1, the interior of which is equipped with a stirring structure for chloroethylene carbonate solution and acid removal agent;

[0031] The filter mechanism 9 is located inside the acid removal box 1 and is used to filter the water in the deacidified vinyl chloride carbonate solution.

[0032] Heating box 7 is located below acid removal box 1 and is used for secondary heating of the chloroethylene carbonate solution after filtration and acid removal.

[0033] The stirring mechanism 8 is located inside the acid removal tank 1 and is used to stir the chloroethylene carbonate solution and the acid removal agent.

[0034] A conveying pipe A2 is fixedly connected to the top of the acid removal box 1, a motor A3 is fixedly connected to the top of the acid removal box 1, and a conveying pipe B4 is fixedly connected to the top of the acid removal box 1.

[0035] A control switch 5 is fixedly connected to the outer wall of the acid removal box 1, an installation platform 6 is fixedly connected to the bottom of the acid removal box 1, a material discharge plate 10 is provided on the inner wall of the acid removal box 1, and a discharge pipe 12 is fixedly connected to the bottom of the acid removal box 1.

[0036] The bottom of the mounting platform 6 is fixedly connected to a support leg 11.

[0037] The stirring mechanism 8 includes a transmission plate 81, which is disposed on the inner wall of the deacidification tank 1. A gear C82 is rotatably connected to the bottom end of the transmission plate 81. A rotating hinge seat 84 is rotatably connected to the transmission plate 81 through the rotation of the gear C82. A gear shaft A83 is rotatably connected to the outer wall of the rotating hinge seat 84. The outer wall of the gear shaft A83 meshes with the gear C82. A gear shaft B85 is rotatably connected to the bottom end of the rotating hinge seat 84. A crank rocker arm 86 is fixedly connected to the bottom end of the gear shaft B85. A connecting shaft 87 is fixedly connected to the bottom end of the crank rocker arm 86. An auxiliary stirring assembly 88 is disposed at the bottom end of the connecting shaft 87.

[0038] The auxiliary stirring assembly 88 includes a mounting plate 883, which is connected to one end of the connecting shaft 87. One end of the mounting plate 883 is rotatably connected to a bearing 882, and the other end of the bearing 882 is fixedly connected to a stirring shaft 881. A stirring plate 884 is fixedly connected to the outer wall of the stirring shaft 881.

[0039] The dehydration and deacidification device for chloroethylene carbonate is equipped with a stirring mechanism 8. The auxiliary stirring component 88 of the stirring mechanism 8 can provide a wider and more uniform stirring action, ensuring that chloroethylene carbonate and the deacidifying agent are fully mixed in the entire reaction system, thereby improving the deacidification efficiency. At the same time, stirring helps to achieve more uniform reaction conditions, thereby improving the purity and consistency of the final product.

[0040] The second embodiment differs from the first embodiment in that the filtration mechanism 9 includes a filter box 91, which is located at the bottom of the acid removal box 1. The outer wall of the filter box 91 has an inlet 92, the inner wall of the filter box 91 has a molecular sieve plate 93, one side of the molecular sieve plate 93 has an adsorption layer 94, the other side of the adsorption layer 94 has a filter plate 95, and the outer wall of the filter box 91 has a rectangular discharge trough 96.

[0041] The dehydration and deacidification device for chloroethylene carbonate is equipped with a filtration mechanism 9, which can effectively remove moisture and acidic impurities from chloroethylene carbonate, ensuring the purity and quality of the final product. Through effective filtration, energy consumption and waste generation can be reduced, which helps to achieve a more environmentally friendly production process.

[0042] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0043] When dehydration and deacidification of chloroethylene carbonate solution are required, the deacidifying agent is first poured into the deacidification tank 1 through the feed pipe B4, and then the chloroethylene carbonate solution is poured into the deacidification tank 1 through the feed pipe A2. Then, the motor A3 is started by the control switch 5. The operation of motor A3, via the transmission plate 81, drives the rotating hinge seat 84 connected to its bottom to rotate. The rotation of the rotating hinge seat 84 drives the gear shaft A83, which is rotatably connected to its outer wall, to move on the outer wall of the gear. The movement of gear shaft A83 on the outer wall of the gear drives the gear shaft B85 meshed with its outer wall to rotate. The rotation of axle B85 drives the crank rocker arm 86 connected to its bottom to rotate. The rotation of the crank rocker arm 86 drives the connecting shaft 87 connected to its bottom to rotate. The rotation of the connecting shaft 87 drives the auxiliary stirring assembly 88 connected to its bottom to rotate. The rotation of the auxiliary stirring assembly 88 stirs the vinyl chloride carbonate solution and the deacidifying agent. As the stirring plate 884 contacts the materials, and with continuous contact, the resistance generated by the continuous contact between the stirring shaft 881 and the stirring plate 884, aided by the bearings, is reduced. The 882 rotates under the influence of force, promoting the fusion reaction between the vinyl chloride carbonate solution and the deacidifying agent. After the vinyl chloride carbonate solution and the deacidifying agent have fully fused and reacted, the solution enters the filter box 91 through the inlet 92 on the outer wall of the filter box 91. The vinyl chloride carbonate solution first undergoes a first layer of filtration through the molecular sieve plate 93 fixedly installed on the inner wall of the filter box 91. After passing through the molecular sieve plate 93 for the first layer of filtration, it then undergoes a second layer of adsorption filtration through the adsorption layer 94 set on one side of the molecular sieve plate 93. After filtration, the solution undergoes three layers of filtration through a filter plate 95 on one side of the adsorption layer 94. After three layers of filtration through the filter plate 95, the solution undergoes four layers of filtration through a molecular sieve plate 93 on the other side of the filter plate 95. After four layers of filtration, impurities and moisture in the ethylene carbonate solution can be filtered out. Then, the rectangular discharge trough 96 on the outer wall of the Rongguang filter box 91 leads to the heating box 7. The operation of the heating box 7 heats the filtered ethylene carbonate solution, which can further remove moisture from the ethylene carbonate solution.
