Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a water separation component of a 3-pentanone distillation tower. Background Art

[0002] 3-Pentanone is used as a solvent and is also an intermediate in drug synthesis. It is a colorless liquid with an acetone odor. Inhalation of moderate concentrations can cause dizziness, nausea, and drowsiness; inhalation of high-concentration vapor can cause coma or even death. It is highly irritating to the eyes and skin, and oral administration can cause nausea, vomiting, diarrhea, and drowsiness. During the production process, it is often necessary to distill it through a distillation tower, and a water separator is required to separate the water in 3-pentanone.

[0003] The "new type of high-efficiency water separator" disclosed in its application number "201420553211.3" "comprises: a water separator tank, a feed port, an overflow port, a funnel, and a water outlet; the feed port is located at the top of the water separator tank, the overflow port is located at the side of the water separator tank, the funnel is located inside the water separator tank, and the water outlet is located at the bottom of the water separator tank". After adding a funnel that is resistant to water shock, the water-containing liquid directly impacts the inside of the funnel, and the water and solvent are separated inside the funnel and come out from the bottom of the funnel together. The solvent overflows after rising, and the water is released after sinking, which greatly improves the efficiency; wherein the upper end of the funnel is seamlessly welded to wrap the feed port to ensure that all the water-containing liquid flows into the interior through the funnel, and the lower end of the funnel is umbrella-shaped to prevent small droplets of liquid from splashing directly from the overflow port after the liquid impacts the liquid surface.

[0004] However, the above method still has the following defects: the water in the solvent sinks and is directly discharged through the water outlet. When the liquid level of the solvent is low, it will be directly discharged through the water outlet along with the water body. When the liquid level is high, the water will be discharged through the overflow port. The water separation quality is poor, and it is difficult to ensure the purity of the solvent.

The stopper 803 is fixedly connected to the top of the slide bar 802. The stopper 803 is located in the same straight line as the photoelectric switch 13 and the reflector 17. The stopper 803 rises to one side of the photoelectric switch 13 to cause an obstruction, that is, to trigger a signal. The float 7 is fixedly connected to the bottom end of the slide bar 802. The density of the float 7 is less than the density of water and greater than the density of 3-pentanone, so that the float 7 can float on the water surface and sink into the inside of 3-pentanone.

[0026] In this embodiment, preferably, the adjustment component 14 includes a bracket 1401 and a screw rod 1402, the bottom end of the bracket 1401 is fixedly connected to the middle of the top of the top plate 11, the top of the screw rod 1402 is rotatably connected to the top of the bracket 1401, the screw rod 1402 is threadedly connected to a threaded sleeve 1404, the surface of the threaded sleeve 1404 is fixedly provided with a lifting plate 1405, both sides of the bottom end of the lifting plate 1405 are fixedly provided with guide columns 1406, the bottom end of the guide column 1406 is connected to the top of the support 12 The bottom end of the screw rod 1402 is rotatably connected to the top end of the top plate 11, and a knob 1403 is fixedly connected to the top end of the screw rod 1402. Two sleeves 15 are fixedly provided on the surface of the top plate 11. The guide column 1406 is slidably connected to the sleeve 15. The screw rod 1402 is rotated by the knob 1403, and the screw rod 1402 can convert the rotational motion into the linear motion of the lifting plate 1405 through the threaded sleeve 1404. The lifting plate 1405 can drive the support 12 to rise and fall through the guide column 1406;

[0027] In this embodiment, preferably, a liquid level window 2 is fixedly provided on the surface of the tank body 1, and the liquid level window 2 facilitates the staff to observe the liquid level inside the tank body 1. A drain pipe 4 is welded to the bottom end of the tank body 1, and the output end of the drain pipe 4 is fixedly connected to the input end of the solenoid valve 3 through a flange. An input pipe 16 is provided on the other side of the top of the tank body 1, and the condensed 3-pentanone can be input into the tank body 1 through the input pipe 16;

[0028] In this embodiment, preferably, a support plate 9 is provided on the surface of the connecting pipe 6, and a baffle 10 can be supported by the support plate 9. The baffle 10 is fixedly provided on the top end of the support plate 9, and the top end of the baffle 10 is fixedly connected to the bottom end of the top plate 11. The baffle 10 can support the top plate 11 and provide protection for the support 12.

[0029] When in use, the staff first installs the photoelectric switch 13 and the reflector 17 on the support 12, and then inputs the condensed 3-pentanone into the tank body 1 through the input pipe 16. After entering the tank body 1, the 3-pentanone can be separated from the water body under the action of different densities. The 3-pentanone rises and the water can fall. Since the density of the float 7 is less than the density of water and greater than the density of 3-pentanone, the float 7 can float on the water surface and sink into the 3-pentanone. As the water level continues to rise, the float 7 and 3-pentanone can be driven to rise, and the 3-pentanone rises to the separation tube 5 and can be discharged from the separation tube 5.

[0030] During the rising process of the float 7, the slide bar 802 can guide and prevent the float 7 from deviating. The float 7 can drive the block 803 to rise. The block 803 rises to one side of the photoelectric switch 13, and can block the photoelectric switch 13 and trigger a signal. The photoelectric switch 13 can open the solenoid valve 3 to drain water, which can prevent the water level from being too high. The 3-pentanone is discharged from the separation tube 5, thereby ensuring the purity of the 3-pentanone and improving the water separation quality. After the water level drops, the float 7 drives the block 803 to fall back, and the photoelectric switch 13 can close the solenoid valve 3, thereby controlling the water level and preventing the 3-pentanone from being discharged from the solenoid valve 3.

[0031] When the drainage water level needs to be adjusted, the staff rotates the screw rod 1402 through the knob 1403. The screw rod 1402 can convert the rotational motion into the linear motion of the lifting plate 1405 through the threaded sleeve 1404. The lifting plate 1405 can drive the support 12 to rise and fall through the guide column 1406, thereby adjusting the height of the photoelectric switch 13 and the reflector 17, thereby realizing the adjustment of the water level.
