[0028] 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.

[0029] Reference Figure 1 and Figure 2, the utility model provides an embodiment: an NVP distillation and purification device, comprising a workbench 1 and a shell 4, a servo motor 3 is fixedly connected to the right side of the top wall of the workbench 1, the output end of the servo motor 3 passes through the inner wall of the shell 4 and is fixedly connected to a rotating column 5, the upper and lower ends of the outer wall of the rotating column 5 are fixedly connected to a slow flow plate 6, the top wall of the shell 4 is connected to a conveying pipe 7, the bottom end of the conveying pipe 7 is connected to a storage box 8, an extraction fan 9 is installed on the front side of the storage box 8, the left side of the storage box 8 is connected to a purification pipeline 10, the left end of the purification pipeline 10 is connected to a collecting box 11, a feed assembly is arranged on the right side of the shell 4, the feed assembly includes a feed valve 12, the left end of the feed valve 12 is connected to the top of the right side of the shell 4, the right bottom end of the shell 4 is connected to a waste removal valve 13, and the front side of the front L-shaped plate 201 is fixedly connected to a control switch 14;

[0030] Specifically, by starting the servo motor 3, the rotating column 5 starts to rotate, driving the two slow flow plates 6 to rotate at a specific speed. This rotation reduces the flow rate of the distilled gas when passing through the slow flow plate 6, and the distillation time is extended. This design makes the distillation process more complete and improves the purification effect. When the purified gas enters the storage box 8 through the conveying pipe 7, the extraction fan 9 is started to guide the purified gas to the collection box 11 through the purification pipeline 10. This step realizes secondary purification. The whole process not only improves the functionality of the device, but also achieves the effect of slowing the flow of the distilled material, further enhancing the purification effect.

[0031] Reference Figure 1 , support columns 17 are fixedly connected to the four corners of the bottom wall of the workbench 1;

[0032] Specifically, these support columns 17 not only provide stability for the workbench 1, but also enhance its load-bearing capacity, thereby maintaining its overall stability and safety.

[0033] Reference Figure 1 and Figure 3 A fixing mechanism 2 is provided at the front side of the workbench 1. The fixing mechanism 2 includes two L-shaped plates 201. The adjacent sides of the two L-shaped plates 201 are respectively fixedly connected to the front and rear sides of the workbench 1. The left side of the L-shaped plate 201 is fixedly connected to an electric telescopic rod 202. The output end of the electric telescopic rod 202 is fixedly connected to a mounting block 203. A clamp 204 is installed at the rear side of the mounting block 203. A threaded knob 205 is rotatably connected to the front side of the mounting block 203. The rear end of the threaded knob 205 penetrates the inner wall of the mounting block 203 and is threadedly connected to the left side of the clamp 204. A plurality of rubber pads 206 are equidistantly installed at the adjacent sides of the two clamps 204.

[0034] Specifically, by starting the two electric telescopic rods 202, the two mounting blocks 203 are displaced toward each other. The displacement of the mounting blocks 203 toward each other not only enables the two clamps 204 to fix and clamp the housing 4, but also largely ensures the stability during the purification process. During the purification process, the material reaction may cause shaking, which will not only affect the purification effect, but also may cause damage to the equipment. By fixing the clamps 204, this situation can be effectively avoided, thereby ensuring the smooth progress of the purification work. In addition, by twisting the two threaded knobs 205, the clamps 204 can be removed from the mounting blocks 203, which not only improves the practicality of the device, but also reduces the maintenance cost, making the entire device more economical and practical. The static friction of the two clamps 204 can be increased by multiple rubber pads 206, so that the fixing effect can be effectively increased.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The control switch 14 is electrically connected to the electric telescopic rod 202, the housing 4 and the extraction fan 9 respectively; a protective shell 15 is provided on the front side of the control switch 14, and the left side of the protective shell 15 is rotatably connected to the front side of the front L-shaped plate 201 through a hinge; an observation window 16 is provided on the right side of the housing 4;

[0036] Specifically, by electrically connecting to the electric telescopic rod 202, the outer shell 4 and the extraction fan 9 respectively, the control switch 14 can complete the opening and closing of the device. The control switch 14 can be protected and prevented from being accidentally touched by the protective shell 15. The observation window 16 is a translucent glass window, so that the status of the items in the outer shell 4 can be clearly displayed.

[0037] Working principle: When starting the distillation and purification work, the material can be fed into the shell 4 through the feed valve 12, and the servo motor 3 is started to make the rotating column 5 drive the two slow flow plates 6 to start rotating, so that the flow rate of the distilled gas is reduced, and the distillation time is increased, so that the purification work is more sufficient. When the purified gas enters the storage box 8 through the conveying pipe 7, the extraction fan 9 is started to make the purified gas enter the collection box 11 through the purification pipeline 10, so that the secondary purification is completed, so that the distillation and purification work can be fully carried out, and the distillate is purified. The material has a slow flow effect, thereby achieving the purpose of strengthening purification and improving the functionality of the device. By starting the two electric telescopic rods 202, the two mounting blocks 203 are displaced toward each other, so that the two clamps 204 can fix and clamp the shell 4, ensuring that during the purification process, there will be no shaking due to the reaction situation, thereby affecting the purification work. By twisting the two threaded knobs 205, the clamps 204 can be removed from the mounting blocks 203, which can facilitate the disassembly and maintenance of the two clamps 204, thereby improving the practicability of the device.

[0038] 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.
