[0023] 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] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a crude distillation device for processing methyl sulfonyl chloride, comprising a distillation barrel 1, a bracket 2 is fixedly connected to the outer wall of the distillation barrel 1, a fixed block 3 is fixedly connected to the outer wall of the distillation barrel 1, a condenser 5 is fixedly connected inside the distillation barrel 1, one end of the condenser 5 is fixedly connected to a fixed shell 6, the fixed shell 6 is fixedly connected to the outer wall of another condenser 5, one end of the other condenser 5 is fixedly connected to a collecting bucket 7, a motor 8 is fixedly connected inside the fixed block 3, a driving sprocket 9 is fixedly connected to the output end of the motor 8, a driven sprocket 11 is rotatably connected inside the distillation barrel 1, a chain 10 is arranged between the driven sprocket 11 and the driving sprocket 9, a gear 12 is fixedly connected to the bottom of the driven sprocket 11, a gear 2 13 in a ring array is rotatably connected inside the distillation barrel 1, and the bottom of the gear 2 13 is fixedly connected to a stirring rod 4, and a filter component is slidably connected inside the fixed shell 6, and the filter component is used to filter and separate relatively large particles of impurities;

[0025] Specifically, when the crude steaming equipment for processing methyl sulfonyl chloride is used for crude steaming operation, the motor 8 is started first. The start of the motor 8 drives the driving sprocket 9 to start rotating. The rotation of the driving sprocket 9 is transmitted to the driven sprocket 11 through the chain 10, so that the driven sprocket 11 also starts to rotate. The rotation of the driven sprocket 11 is further transmitted to the gear 1 12. While the gear 1 12 is rotated by force, it transmits power to the gear 2 13. The gear 2 13 rotates accordingly. The rotation of the gear 2 13 drives the stirring rod 4, so that the stirring rod 4 effectively stirs the distillate inside the distillation barrel 1. Through stirring, The distillate can be heated evenly, which helps to improve the distillation efficiency and ensure the product quality. As the distillation process proceeds, the volatile components in the distillate begin to evaporate to form steam, which is condensed through the condenser 5. The condensed liquid flows into the collection barrel 7 for storage. The setting of the collection barrel 7 is to conveniently collect and store the condensed liquid to prepare for subsequent processes. The design of the entire crude steaming equipment takes into account the convenience and efficiency of operation. Through a series of mechanical transmission and power transmission, effective stirring and condensation of the distillate are achieved, thereby ensuring the processing quality of methylsulfonyl chloride.

[0026] Reference Figure 2 - Figure 4 The filter assembly includes a connecting block 14 and a filter screen 15, the interior of the connecting block 14 is fixedly connected to the outer wall of the filter screen 15, and both sides of the outer wall of the connecting block 14 are slidably connected to the interior of the fixed shell 6;

[0027] Specifically, in the crude distillation equipment for processing methylsulfonyl chloride, the filter screen 15 can prevent larger particles from entering the condensation system, thereby preventing these particles from causing wear or blockage to the equipment and extending the service life of the equipment.

[0028] Reference Figure 2 - Figure 4 A rotating handle 16 is rotatably connected to one side of the outer wall of the fixed shell 6, a limiting block 22 is slidably connected inside the connecting block 14, a worm 17 is fixedly connected to one side of the outer wall of the rotating handle 16, two worm wheels 18 are rotatably connected inside the fixed shell 6, and the worm wheels 18 are meshed with the worm 17, a transmission column 21 is fixedly connected to one side of the outer wall of the limiting block 22, a transmission column 21 is slidably connected to the outer wall of the transmission column 21 with a transmission plate 20, an inclined groove 24 is provided inside the transmission plate 20, and the outer wall of the transmission column 21 is slidably connected inside the inclined groove 24, a toothed plate 19 is fixedly connected to one side of the outer wall of the transmission plate 20, and the toothed plate 19 is meshed with the worm wheel 18, and a handle 23 is fixedly connected to one side of the outer wall of the connecting block 14;

[0029] Specifically, after using the crude steaming equipment for a long time, in order to maintain the normal operation of the equipment and ensure the efficiency of the distillation process, the filter screen 15 needs to be regularly disassembled and cleaned. First, the handle 16 is turned. This action will be transmitted to the worm 17 through the mechanical transmission system, so that the worm 17 starts to rotate. The rotation of the worm 17 will further drive the worm wheel 18 to rotate. The rotational movement of the worm wheel 18 is the key to the entire disassembly process, because it will eventually realize the disassembly of the filter screen 15 through a series of mechanical linkages. As the worm wheel 18 rotates, the tooth plate 19 will move a predetermined distance to the lower left. The movement of the tooth plate 19 will transmit the force to the transmission plate 20 and the transmission column 21 through the transmission plate On the limit block 22, the limit block 22 will move to the right under the action of force, thereby releasing its limiting effect on the inside of the connecting block 14. The connecting block 14 is a key component for fixing the filter screen 15 on the equipment. The release of the limit block 22 makes the filter screen 15 no longer restricted and can move freely. At this time, the operator can hold the handle 23, and the handle 23 is designed to easily grab and move the filter screen 15. By holding the handle 23, the operator can easily remove the filter screen 15 from the equipment. After removing the filter screen 15, it can be thoroughly cleaned and inspected to remove accumulated impurities and sediments to ensure the performance of the filter screen 15 and the efficiency of the distillation process.

[0030] Working principle: When using the crude steaming equipment for processing methyl sulfonyl chloride, when performing crude steaming, first start the motor 8, the motor 8 drives the active sprocket 9 to rotate, and then the rotation of the active sprocket 9 drives the driven sprocket 11 to rotate through the chain 10, so that the gear 12 is forced to rotate, and at this time, the rotation of the gear 12 drives the gear 2 13 to rotate, so that the stirring rod 4 stirs the distillate inside the distillation barrel 1 to make it evenly heated, and then its steam is condensed through the condenser 5 and enters the collection barrel 7 for storage, preparing for the next process. After using the device for a long time, when it is necessary to disassemble and clean the filter screen 15, first turn the rotating handle 16, and the rotating handle 16 drives the worm 17 to rotate, so that the worm wheel 18 is forced to rotate, and the rotation of the worm wheel 18 will drive the tooth plate 19 to move a distance to the lower left, so that the transmission plate 20 can drive the limit block 22 to move to the right through the transmission column 21, so that the limit block 22 is separated from the inside of the connecting block 14, and its limit is released, and then the handle 23 can be held to take out the filter screen 15.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
