All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides an energy-saving n-butyric acid rectification device, which includes a box body 1. A bracket 2 is fixedly arranged on the surface of the box body 1, and a rectification tower body 3 is fixedly arranged on the inner wall of the bracket 2. A filter shell 4 is slidably connected to the inner wall of the box body 1. Feed grooves 7, discharge grooves 8 and two dovetail grooves 9 are respectively formed on the surface of the filter shell 4. A filter net 10 is fixedly arranged on the inner wall of the discharge groove 8. Dovetail seats 11 are slidably connected to the inner walls of the two dovetail grooves 9. A feed assembly 5 is arranged on one side of the filter shell 4. A submersible pump 23 is fixedly arranged on the inner wall of the bottom end of the box body 1. A feeding pipe 24 is fixedly arranged at the liquid outlet end of the submersible pump 23. One end of the feeding pipe 24 penetrates through the surface of the rectification tower body 3 and is located inside the rectification tower body 3. The raw material containing n-butyric acid is added into the filter shell 4 through the feed assembly 5. The liquid containing n-butyric acid in the raw material passes through the filter net 10 and enters the inside of the box body 1. The filter net 10 filters out particulate impurities to prevent the particulate impurities from being pumped into the rectification tower body 3 and ensure the rectification effect. When the liquid level rises, it will submerge the submersible pump 23. Start the submersible pump 23, and the submersible pump 23 pumps the liquid into the rectification tower body 3 to rectify n-butyric acid.

[0026] The feed assembly 5 includes an elbow pipe 51 and an adjustment assembly 6. The elbow pipe 51 is fixedly arranged at the top of the box body 1. One end of the elbow pipe 51 is fixedly provided with a telescopic rubber pipe 52. One end of the telescopic rubber pipe 52 is fixedly provided with a guide pipe 53 that slides with the feed groove 7. A first electric valve is fixedly arranged on the surface of the elbow pipe 51. Move the guide pipe 53. When the guide pipe 53 slides into the feed groove 7, the filter shell 4 is limited in the vertical direction through the adjustment assembly 6 and the guide pipe 53, improving the stability of the filter shell 4, and the raw material is replenished into the filter shell 4 through the guide pipe 53. When the guide pipe 53 disengages from the feed groove 7, the limit of the filter shell 4 in the vertical direction is released, and it slides out of the filter shell 4 upward to pour out particulate impurities and clean the filter net 10, which is convenient for maintenance.

[0027] The adjusting assembly 6 includes an adjusting motor 61 and two stoppers 63. The adjusting motor 61 is fixedly arranged on one side of the box body 1. A transmission rod 62 is fixedly arranged on the transmission shaft of the adjusting motor 61. Both of the two stoppers 63 are fixedly arranged on the inner wall of the front surface of the box body 1. A connecting lead screw 64 is rotatably connected between the two stoppers 63 through a sealed bearing. A moving frame 65 is threadedly connected to the surface of the connecting lead screw 64 through a lead screw nut. The inner wall of the moving frame 65 is fixedly connected to the surface of the material guiding pipe 53. By starting the adjusting motor 61, the adjusting motor 61 drives the connecting lead screw 64 to rotate through the transmission rod 62, and the connecting lead screw 64 drives the material guiding pipe 53 to move horizontally through the moving frame 65, so as to make the material guiding pipe 53 slide into or out of the feeding groove 7, without the need for manual movement of the material guiding pipe 53.

[0028] The adjusting motor 61 is a forward and reverse rotation motor. One end of the transmission rod 62 is fixedly connected to one end of the connecting lead screw 64. The contact part between one end of the transmission rod 62 and the box body 1 is rotatably connected through a sealed bearing. The front surface of the moving frame 65 is slidably connected to the inner wall of the front surface of the box body 1. The box body 1 limits the movement of the moving frame 65 through the inner wall of the front surface to prevent it from rotating along with the rotation of the connecting lead screw 64.

[0029] An outlet opening 12 is formed on the surface of the box body 1. A sealing cover 13 is hinged to the inner wall of the outlet opening 12. A handle is fixedly arranged at the top end of the sealing cover 13. Heat preservation paint is coated on the surface of the sealing cover 13 and the surface of the box body 1 to keep warm the new liquid containing n-butyric acid preheated by the waste liquid inside the box body 1. The contact parts between the box body 1 and the two dovetail seats 11 are fixedly connected. By opening the sealing cover 13 and sliding out the filter shell 4 upwards, the dovetail seats 11 limit the filter shell 4 in the horizontal direction to improve the stability of the filter shell 4, and guide the vertical movement of the filter shell 4 through the dovetail groove 9.

[0030] Receiving grooves 14 are formed at the top ends of the two dovetail seats 11. Electric push rods 15 are fixedly arranged on the inner walls of the two receiving grooves 14. Push blocks 16 are fixedly arranged at the telescopic ends of the two electric push rods 15. Force-receiving blocks 17 are slidably connected to the top ends of the two dovetail seats 11. Card slots engaged with the push blocks 16 are formed at the bottom ends of the two force-receiving blocks 17. The contact parts between the two force-receiving blocks 17 and the box body 1 are slidably connected. The surfaces of the two force-receiving blocks 17 are respectively connected to the inner walls of the two dovetail grooves 9. The two force-receiving blocks 17 and the two dovetail seats 11 are both made of heat-insulating materials. The heat-insulating force-receiving blocks 17 and dovetail seats 11 protect the electric push rods 15 when preheating the raw materials inside the waste liquid preheating box body 1. By starting the electric push rods 15, the telescopic ends of the electric push rods 15 extend and push the push blocks 16 to move. The push blocks 16 push the force-receiving blocks 17 to move, and the force-receiving blocks 17 drive the filter shell 4 to move upwards, so as to push out the filter shell 4, facilitating the removal of the filter shell 4. The push blocks 16 can be separated from the force-receiving blocks 17, so that the filter shell 4 can be separated from the box body 1.

[0031] The inner wall of the rectifying tower body 3 is fixedly provided with a tray 18 and an electric heating rod 19. The surface of the rectifying tower body 3 is fixedly provided with a drain pipe 20, a steam outlet pipe 25 and a reflux pipe 26 respectively. The surface of the drain pipe 20 is fixedly provided with a second electric valve. The surface of the steam outlet pipe 25 is fixedly provided with a third electric valve. One end of the reflux pipe 26 is fixedly provided with a spray head 27. The liquid containing n-butyric acid at the bottom inside the rectifying tower body 3 is heated by the electric heating rod 19, and the rectified waste liquid is discharged through the drain pipe 20.

[0032] One end of the drain pipe 20 is fixedly provided with a heat exchange pipe 21. The heat exchange pipe 21 is placed inside the box body 1. One end of the heat exchange pipe 21 is fixedly provided with a waste liquid pipe 22. One end of the waste liquid pipe 22 penetrates through the inner wall on one side of the box body 1 and is placed outside the box body 1. The high-temperature waste liquid will flow through the heat exchange pipe 21 when being discharged, and the liquid containing n-butyric acid inside the box body 1 is heated through the heat exchange pipe 21, so as to preheat the new liquid, which is more energy-saving.

[0033] During use, first start the adjusting motor 61. The adjusting motor 61 drives the feeding pipe 53 to move horizontally through the transmission rod 62, the connecting lead screw 64 and the moving frame 65, so that the feeding pipe 53 slides into the feeding groove 7. Then open the first electric valve, and add the raw material containing n-butyric acid into the filter housing 4 through the cooperation of the elbow pipe 51, the telescopic rubber pipe 52 and the feeding pipe 53. The liquid containing n-butyric acid in the raw material will pass through the filter net 10 and enter the inside of the box body 1. The particulate impurities are filtered through the filter net 10 to avoid the particulate impurities being pumped into the rectifying tower body 3, ensuring the rectifying effect. The liquid level gradually rises and will submerge the submerged pump 23. Start the submerged pump 23, and the submerged pump 23 pumps the liquid into the rectifying tower body 3 to rectify n-butyric acid;

[0034] Further, when it is necessary to discharge the particulate impurities, open the sealing cover 13, start the adjusting motor 61, and the adjusting motor 61 drives the connecting lead screw 64 to rotate reversely through the transmission rod 62. The connecting lead screw 64 will drive the feeding pipe 53 to move reversely through the moving frame 65, so that the feeding pipe 53 is separated from the feeding groove 7, and further releases the limit of the feeding pipe 53 on the filter housing 4. Then start the electric push rod 15, and the telescopic end of the electric push rod 15 extends and pushes the push block 16 to move upward. The push block 16 drives the filter housing 4 to move upward through the stress block 17, so as to push out the filter housing 4, without manually pulling the filter housing 4 upward, which is more labor-saving.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
