[0002] Coal tar is a byproduct of coal dry distillation and contains a variety of organic compounds, such as aromatic hydrocarbons, phenolic compounds, and ketones. Due to its complex composition and the high economic value of many components, useful components can be extracted through multi-component separation technology, thereby reducing waste and improving resource utilization.
[0003] The separation process of multiple components in coal tar often includes distillation, condensation, and extraction, but existing continuous separation devices have shortcomings. First, during the distillation of coal tar, the existing separation devices do not heat the coal tar quickly and evenly enough, and the coal tar often contains particulate impurities, affecting the distillation efficiency. Second, existing separation devices lack efficient cleaning structures; after the coal tar distillation is completed and the liquid is discharged, a certain amount of residual dirt still adheres to the inner wall, which can easily cause cross-contamination. Therefore, a continuous multi-component separation device for coal tar is proposed to solve the above problems. Utility Model Content

[0031] Reference Figure 1 and Figure 3 The filter assembly includes a filter box 20, a filter screen 21, and two vibration motors 22. The filter box 20 is fixedly connected to the distillation tank 1. The filter screen 21 is fixedly installed on the inner wall of the filter box 20 and is set at an angle to filter particulate impurities in the coal tar. Vibration motors 22 are fixedly installed on both sides of the bottom end of the filter screen 21 to periodically vibrate the filter screen 21 and guide particulate impurities to the bottom of the filter screen 21 to avoid clogging and affecting the flow of coal tar.
[0032] Reference Figure 1 The front of the filter box 20 is fixedly installed with a cover plate 23 by bolts, which can be removed to clean the filter material inside the filter box 20. The top of the filter box 20 is fixedly connected to an inlet valve 9 for inputting coal tar.
[0033] Reference Figure 2 The spray assembly includes an annular pipe 17 and several nozzles 18. The annular pipe 17 is fixedly connected to the top of the inner wall of the distillation tank 1, and several nozzles 18 are uniformly fixedly connected to the bottom of the annular pipe 17.

The cleaning valve 19 is connected to an external water supply pipe for inputting cleaning liquid into the annular pipe 17.
[0035] Reference Figure 2 and Figure 4 The input end of the blower 4 is connected to the interior of the distillation tank 1 to guide steam. The interior of the condenser 6 is fixedly connected to a spiral tube 7, and the top end of the spiral tube 7 is fixedly connected to the gas pipe 5, which can increase the movement path of the steam and effectively cool it into a liquid state.

[0038] Working principle: Coal tar is introduced into the device through the inlet valve 9. A filter box 20 is installed at the front end of the distillation tank 1. The filter screen 21 within the box filters particulate impurities from the coal tar, preventing them from affecting the evaporation rate of the liquid. A vibrating motor 22 periodically vibrates the filter screen 21, guiding the particulate impurities to the bottom of the screen to prevent blockage and ensure proper coal tar flow. An encased heating coil 3 heats the coal tar. A reduction motor 11 drives the spiral blades 13 at the bottom of the vertical shaft 12 to rotate, agitating the liquid and making heating faster and more uniform, improving distillation efficiency. Upon reaching a certain boiling point, the components in the coal tar are converted into vapor, which, guided by the blower 4, is introduced through the gas pipe 5 into the spiral tube 7 of the condenser tank 6. The condenser tank 6 has a coolant inlet on its side wall. The outlet, through the circulation of coolant, cools the steam, causing it to liquefy again and fall into the extraction tank 8. Solvent is introduced through the valve port on the side of the extraction tank 8 to further separate the components. Finally, the liquid can be discharged by opening the drain valve 10 below the extraction tank 8. The remaining liquid in the distillation tank 1 can be discharged by opening the drain valve 10 below it. After the coal tar multi-component separation device has finished working, the cleaning valve 19 is connected to the external water supply pipe to introduce cleaning liquid into the annular pipe 17 and spray it evenly from several nozzles 18 below to rinse the inner wall of the distillation tank 1. At the same time, the reduction motor 11 is started to drive the side scraper 14 and the bottom scraper 15 to rotate, assisting in scraping off the adhering residual dirt, thereby cleaning the inner wall of the distillation tank 1 and avoiding cross-contamination caused by residual dirt. The wastewater can be discharged by opening the drain valve 10.
