[0002] Currently, chloroacetic acid is mostly produced using the sulfur process. After adding glacial acetic acid and sulfur powder to the reactor, it is heated to a specific temperature and chlorine gas is continuously introduced. Since the chlorination reaction requires a temperature of over 95 degrees Celsius, the reactor needs to be continuously heated to process the materials inside.
[0003] In an existing reactor used for the production of chloroacetic acid, although it has the characteristics of good reaction effect and production efficiency.
[0004] However, this type of reactor for producing chloroacetic acid has the following disadvantages: during the use of the reactor, it is not easy for personnel to know the viscosity of the material inside the reactor, which requires personnel to stop the operation of the reactor to observe it, affecting the production efficiency of the reactor, and it is not easy for personnel to recover and utilize the waste heat generated after the use of the reactor. Utility Model Content
[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a reaction vessel for the production of chloroacetic acid. This effectively solves the problems of existing technologies where it is difficult for personnel to ascertain the viscosity of the materials inside the reaction vessel during operation, necessitating the cessation of operation to observe the vessel and thus affecting production efficiency. Furthermore, it is difficult to recover and utilize the waste heat generated after the reaction vessel's use.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0012] Preferably, reinforcing rings are fixedly connected to both sides of the outer surface of the reaction vessel, and the outer surface of the reinforcing rings is coated with an anti-oxidation coating.
[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0014] 1. This utility model, through the cooperative use of the reaction tank and the viscosity prediction component, allows personnel to predict the viscosity of the material inside the reaction tank when processing the material inside the reaction tank by using the current data displayed by the ammeter to predict the current used by the drive motor.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] The present invention will be further described below with reference to the embodiments.
[0024] Example: Refer to Figures 1 to 4 A reaction vessel for producing chloroacetic acid includes a reaction vessel 1, a top cover 2 snapped onto the top surface of the reaction vessel 1, and a drive motor 3 fixedly installed in the middle of the top surface of the top cover 2.
[0025] When personnel use the reactor for producing chloroacetic acid to process materials, they can place the materials to be processed inside the reactor 1. Then, they can turn on the power to the drive motor 3, causing the drive motor 3 to stir inside the reactor 1, thus rapidly processing the materials inside. Personnel can then observe the current data inside the ammeter 41, allowing them to predict the current used by the drive motor 3 and thus the viscosity of the materials inside the reactor 1. After processing the materials in the reactor 1, personnel can turn on the power to the heat extraction pump 62, causing the extraction pipe 5 to extract the hot air inside the reactor 1, transferring the waste heat to the waste heat recovery tank 61. The waste heat recovery tank 61 then heats the water inside, which can then be drained using the drain pipe 9, thus facilitating the recovery and utilization of waste heat.
[0026] Reference Figures 1 to 4 One side of the drive motor 3 is electrically connected to a thickening prediction component 4. The thickening prediction component 4 includes an ammeter 41 fixedly connected to the other side of the surface of the reaction vessel 1. One side of the ammeter 41 is electrically connected to a current line 42, and one end of the current line 42 is electrically connected to the power terminal of the drive motor 3.
[0027] With the setting of viscosity prediction component 4 and reaction tank 1, when personnel need to process the material inside the reaction tank 1, they can use the current data displayed by ammeter 41 to predict the viscosity of the material inside the reaction tank 1 by the current used by drive motor 3. When the material is viscous, the current data used by drive motor 3 is larger, which makes it easier for staff to predict the viscosity of the material inside the reaction tank 1.
[0028] Reference Figures 1 to 4 An extraction pipe 5 is inserted into one side of the front of the reaction tank 1. A waste heat recovery assembly 6 is inserted into one end of the extraction pipe 5. The waste heat recovery assembly 6 includes a waste heat recovery box 61 fixedly connected to the surface of the reaction tank 1. A heat extraction pump 62 is fixedly installed on the top of the waste heat recovery box 61. The input end of the heat extraction pump 62 is inserted into the axis at one end of the extraction pipe 5. A heat-conducting plate 7 is embedded in the inner wall of the waste heat recovery box 61. A baffle 8 is fixedly connected to the front of the waste heat recovery box 61.
[0029] With the setup of reaction tank 1 and waste heat recovery component 6, after the reaction tank 1 has finished processing the material, the residual heat energy inside the reaction tank 1 is connected to the power supply of heat extraction pump 62 by the staff, and is transported to the inside of waste heat recovery box 61 through extraction pipe 5, thereby facilitating the recovery of waste heat inside the reaction tank 1.
[0030] Reference Figures 1 to 4 A drain pipe 9 is inserted into the front of the baffle 8, and a control valve is inserted into the surface of the drain pipe 9.
[0031] With the installation of drain pipe 9 and control valve, when personnel need to drain the water inside waste heat recovery box 61, they can turn the control valve to open drain pipe 9, thus facilitating drainage.
[0032] Reference Figures 1 to 4 Both sides of the outer surface of the reaction vessel 1 are fixedly connected with reinforcing rings 10, and the outer surface of the reinforcing rings 10 is covered with anti-oxidation coating.
[0033] The reinforcement of reaction vessel 1 is improved by setting the reinforcing ring 10;
[0034] Working Principle: When personnel use the reactor for producing chloroacetic acid to process materials, they can place the materials to be processed inside the reactor 1. Then, the power supply to the drive motor 3 is turned on, causing the drive motor 3 to stir inside the reactor 1, rapidly processing the materials. Personnel can then observe the current data inside the ammeter 41 to predict the current used by the drive motor 3, thus facilitating the prediction of the viscosity of the materials inside the reactor 1. After processing the materials in the reactor 1, the personnel can turn on the power supply to the heat extraction pump 62, causing the extraction pipe 5 to extract the hot air inside the reactor 1, transferring the waste heat to the waste heat recovery tank 61. The waste heat recovery tank 61 then heats the water inside, which can then be drained using the drain pipe 9, thus facilitating the recovery and utilization of waste heat.
