The outer wall of the water washing inlet pipe 110 is equipped with a solenoid valve 111, which is used to control the introduction of the raw materials after the reaction inside the reactor 102 into the water washing tank 112. After the water washing is completed, the water pump 113 is started.

The light components such as dichloroethane and vinyl sulfite obtained after separation are discharged through the second discharge pipe 118 and the first discharge pipe 116 respectively. At the same time, solenoid valves 117 are installed on the outer walls of both the first discharge pipe 116 and the second discharge pipe 118, which are used to control the discharge of the separated products.

[0023] As Figure 3 , Figure 4 shown, the mixing and stirring assembly 2 includes a first motor 201. The bottom of the first motor 201 is fixedly connected to the top of the base 101. The output end of the first motor 201 is fixedly connected to a first bevel gear 202. The bottom of the first bevel gear 202 is meshed with a second bevel gear 203. The bottom of the second bevel gear 203 is fixedly connected to a hollow rotating rod 204 that is rotationally connected to the water washing tank 112.

[0024] As Figure 3 , Figure 4As shown, a hollow fixed column 205 rotatably connected to the outer wall of the hollow rotating rod 204 is fixedly connected to the inner top wall of the water washing tank 112. A first gear 206 is fixedly connected to the outer wall of the hollow fixed column 205.

A second gear 208 meshing with the first gear 206 is fixedly connected to the top of each of the three rotating shafts 209. The bottom of each of the three rotating shafts 209 penetrates to the bottom of the rotating rod 207 and is fixedly connected to a third gear 210. A second rotating shaft 211 is rotatably connected to the bottom of one side of each of the three rotating rods 207 away from the hollow fixed column 205. A fourth gear 212 meshing with the third gear 210 is fixedly connected to the bottom of each of the three second rotating shafts 211. A connecting rod 213 is fixedly connected to the bottom of each of the three fourth gears 212. A spiral stirring rod 214 is fixedly connected to the bottom of one side of each of the three connecting rods 213 away from the fourth gear 212.

[0025] When it is necessary to mix and stir the raw materials and the water washing liquid inside the water washing tank 112, first, the water washing liquid is introduced into the water washing tank 112 through the set cleaning water introduction assembly 3. Then, the first motor 201 is started, and its output end drives the first bevel gear 202 to rotate. The first bevel gear 202 meshes with the second bevel gear 203, thereby driving the second bevel gear 203 to rotate. The rotation of the second bevel gear 203 drives the hollow rotating rod 204 fixedly connected to its bottom to rotate. When the hollow rotating rod 204 rotates, it drives the rotating rod 207 to rotate. Since the first gear 206 meshes with the second gear 208, the second gear 208 will rotate around the first gear 206 while also rotating on its own axis. The rotation of the second gear 208 causes the rotating shaft 209 to rotate as well. The rotation of the rotating shaft 209 drives the third gear 210 fixedly connected to its bottom to rotate. The rotation of the third gear 210 causes the fourth gear 212 meshing with it to rotate. The rotation of the fourth gear 212 drives the connecting rod 213 and the spiral stirring rod 214 to rotate. The spiral stirring rod 214 continuously rotates to fully stir the vinylene sulfite and the water washing liquid in the water washing tank 112, thereby accelerating the dissolution and removal of impurities and unreacted substances, improving the water washing efficiency, and reducing the water washing time and water consumption.

[0026] As Figure 4As shown in the figure, the cleaning water introduction component 3 includes a cleaning tank 301. The bottom of the cleaning tank 301 is fixedly connected to the top of the water washing tank 112. The top of the right side wall of the cleaning tank 301 is fixedly connected with a cleaning guide pipe 302. The cleaning tank 301 is used to store the water washing liquid. The top of the right side wall of the cleaning tank 301 is connected to the cleaning guide pipe 302 for replenishing the water washing liquid into the cleaning tank 301. A second water pump 303 is fixedly connected to the top of the water washing tank 112. The right end water inlet of the second water pump 303 is fixedly connected to the cleaning tank 301. The top end water outlet of the second water pump 303 is fixedly connected with a second water outlet pipe 304. One end of the second water outlet pipe 304 away from the second water pump 303 is rotatably connected to the inner wall of the bevel gear 203. A plurality of water mist nozzles 305 distributed in an annular array are fixedly connected to the bottom of the outer wall of the hollow rotating rod 204.

[0027] When it is necessary to add the water washing liquid into the water washing tank 112, start the second water pump 303. The second water pump 303 pumps the water washing liquid inside the cleaning tank 301 into the water washing tank 112 through the second water outlet pipe 304 and the hollow rotating rod 204. A plurality of water mist nozzles 305 distributed in an annular array are fixedly connected to the bottom of the outer wall of the hollow rotating rod 204. When the hollow rotating rod 204 rotates, the cleaning water enters the hollow rotating rod 204 through the second water outlet pipe 304 and then sprays out from the water mist nozzles 305, evenly spraying the water washing liquid in the water washing tank 112 to ensure that the water washing liquid is in full contact with the reacted raw materials and further improve the water washing effect.

[0028] As Figure 5 As shown in the figure, the impurity export component 4 includes a filter screen 401. The filter screen 401 is fixedly connected to the lower part of the inner wall of the water washing tank 112. A scraper 402 that fits the top of the filter screen 401 is fixedly connected to the bottom of the hollow rotating rod 204. Two symmetrically arranged leakage grooves 403 are formed at the top of the filter screen 401. A second motor 404 is fixedly connected to the lower front side of the outer wall of the water washing tank 112. A filter screen slag holding chamber 405 is fixedly connected to the bottom of the filter screen 401. The output end of the second motor 404 penetrates into the inside of the water washing tank 112 and is fixedly connected with a screw conveyor 406 located inside the filter screen slag holding chamber 405. A slag discharge pipe 407 communicated with the filter screen slag holding chamber 405 is fixedly connected to the lower front side of the outer wall of the water washing tank 112. A slag discharge valve 408 is fixedly connected to the outer wall of the slag discharge pipe 407.

[0029] When it is necessary to discharge the impurities generated due to water washing inside the water washing tank 112 outside the device, the filter screen 401 is used to filter the impurities generated during the water washing process. When the hollow rotating rod 204 rotates, the scraper 402 also rotates accordingly, scraping the impurities on the filter screen towards the leakage trough 403. The impurities fall into the filter screen slag chamber 405 through the leakage trough 403. When the second motor 404 is started, the auger 406 rotates to convey the impurities to the slag discharge pipe 407. When slag discharge is required, the slag discharge valve 408 is opened, and the impurities can be discharged from the water washing tank 112 through the slag discharge pipe 407, enabling the device to regularly discharge the impurities generated during the water washing process from the water washing tank, preventing the impurities from adhering to the raw materials, and thus improving the purity and quality of the product.

[0030] It should be particularly noted that the meter 105, the water mist nozzle 305, the horizontal separation tank 115, and each solenoid valve are all prior arts and will not be elaborated here.

[0031] The working principle of the ethylene sulfite continuous water washing and separation device will be specifically described below.

[0032] As Figures 1-5 shown, the base 101 is stably placed on the ground, providing stable support for the entire device. The mixing tank 104 is installed on the top of the reaction kettle 102. The mixing tank 104 is used for preliminary mixing of raw materials such as thionyl chloride. The meter 105 is fixed on the top of the mixing tank 104. Through the meter 105, the amount of raw materials entering the interior of the reaction kettle 102 can be accurately measured. The top of the meter 105 is connected to the raw material inlet pipe 106. The outer wall of the raw material inlet pipe 106 is equipped with a feed valve 107, which can accurately control the amount of raw materials entering. The outer wall of the raw material discharge pipe 108 is equipped with a discharge valve 109, which is used to control the mixed raw materials to enter the reaction kettle 102. The outer wall of the water washing inlet pipe 110 is equipped with a first solenoid valve 111, which is used to control the introduction of the raw materials after the reaction inside the reaction kettle 102 into the water washing tank 112. After the water washing is completed, the water pump 113 is started. The water pump 113 guides the raw materials after water washing through the outlet pipe 114 into the horizontal separation tank 115 for separation treatment. The light components such as dichloroethane and ethylene sulfite obtained after separation are discharged through the second outlet pipe 118 and the first outlet pipe 116 respectively. At the same time, the outer walls of the first outlet pipe 116 and the second outlet pipe 118 are both equipped with a second solenoid valve 117, which is used to control the discharge of the separated products.

[0033] When it is necessary to add the water washing liquid into the water washing tank 112, start the second water pump 303. The second water pump 303 pumps the water washing liquid inside the cleaning tank 301 into the water washing tank 112 through the second water outlet pipe 304 and the hollow rotating rod 204. A plurality of water mist nozzles 305 distributed in an annular array are fixedly connected to the bottom of the outer wall of the hollow rotating rod 204. When the hollow rotating rod 204 rotates, the cleaning water enters the hollow rotating rod 204 through the second water outlet pipe 304 and then sprays out from the water mist nozzles 305, evenly sprinkling the water washing liquid in the water washing tank 112 to ensure that the water washing liquid is in full contact with the reacted raw materials, further improving the water washing effect.

[0034] When it is necessary to mix and stir the raw materials and the water washing liquid inside the water washing tank 112, start the first motor 201. The output end thereof drives the first bevel gear 202 to rotate. The first bevel gear 202 meshes with the second bevel gear 203, thereby driving the second bevel gear 203 to rotate. The rotation of the second bevel gear 203 drives the hollow rotating rod 204 fixedly connected to its bottom to rotate. When the hollow rotating rod 204 rotates, it drives the rotating rod 207 to rotate. Since the first gear 206 meshes with the second gear 208, the second gear 208 will rotate around the first gear 206 while also rotating on its own axis. The rotation of the second gear 208 causes the rotating shaft 209 to rotate as well. The rotation of the rotating shaft 209 drives the third gear 210 fixedly connected to its bottom to rotate. The rotation of the third gear 210 causes the fourth gear 212 meshing with it to rotate. The rotation of the fourth gear 212 drives the connecting rod 213 and the spiral stirring rod 214 to rotate. The spiral stirring rod 214 continuously rotates to fully stir the vinylene sulfite and the water washing liquid in the water washing tank 112, thereby accelerating the dissolution and removal of impurities and unreacted substances, improving the water washing efficiency, and reducing the water washing time and water consumption.

[0035] When it is necessary to discharge the impurities generated due to water washing inside the water washing tank 112 out of the device, the filter screen 401 is used to filter the impurities generated during the water washing process. When the hollow rotating rod 204 rotates, the scraper 402 also rotates accordingly, scraping the impurities on the filter screen towards the leakage trough 403. The impurities fall into the filter screen slag chamber 405 through the leakage trough 403. When the second motor 404 is started, the auger 406 rotates, transporting the impurities to the slag discharge pipe 407. When it is necessary to discharge the slag, open the slag discharge valve 408, and the impurities can be discharged from the water washing tank 112 through the slag discharge pipe 407, enabling the device to regularly discharge the impurities generated during the water washing process from the water washing tank, preventing the impurities from adhering to the raw materials, and thus improving the purity and quality of the product.

[0036] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, any modifications or improvements made without departing from the spirit and concept of the present utility model are within the protection scope of the present utility model.
