Description

Technical Field

[0001] This application relates to the field of hydrolysis reactors, and more particularly to a water separation device for a hydrolysis reactor. Background Technology

[0002] A hydrolysis reactor is an experimental instrument widely used in the fields of chemistry, medicine, and food. Its main function is to carry out hydrolysis reactions on substances under high temperature and high pressure.

[0003] In related technologies, reference can be made to Chinese utility model patent with authorization announcement number CN204841656U, which discloses a hydrolysis reactor, including a servo motor, gear cover, loose flange, steam outlet, discharge port, drive shaft, liquid inlet, impeller agitator, jacket, reactor body, condensate outlet, observation device, opening device, and temperature sensing device. The upper middle part of the reactor body is connected to the loose flange, the lower middle part of the reactor body is connected to the discharge port, and the lower right side of the reactor body is connected to the condensate outlet. The jacket is fitted around the outside of the reactor body. The upper part of the loose flange is connected to the servo motor, and the lower part is connected to the drive shaft. The bottom end of the drive shaft is connected to the impeller agitator to facilitate the stratification of chemical and pharmaceutical hydrolysis reactions.

[0004] After the hydrolysis reaction of the triphenylphosphine process is completed, the oil layer needs to be washed with water 2 to 3 times. After washing, it is left to stand and the water layer is drained. There is a part of the oil layer in the water layer, which causes some of the oil layer to be carried away after washing, resulting in waste. The loss from washing is relatively large. Utility Model Content

[0005] To address the issue of significant water loss during washing when an oil layer exists within the water layer, this application provides a water separation device for a hydrolysis reactor.

[0006] The water separation device for a hydrolysis reactor provided in this application adopts the following technical solution:

[0007] A water separation device for a hydrolysis reactor includes a water separation tank. The water separation tank contains several water-separating plates arranged parallel to each other, dividing the water separation tank into several water tanks. An inlet pipe is provided on the water separation tank. A filter element is installed at the inlet pipe. An oil tank is located on the side of the water separation tank away from the filter element. An oil-pushing element is installed on the side of the water separation tank facing the oil tank, used to push floating oil on the water separation tank to the oil tank. An oil outlet pipe is provided on the side of the water separation tank facing the oil tank, and a water outlet pipe is provided at the bottom of the water separation tank.

[0008] By adopting the above technical solution, the water layer in the hydrolysis reactor is transported to the water distribution tank through the water inlet pipe, filtered by the filter element, and flows to the water tank on the side of the oil tank through the water baffle plate. The oil pusher pushes the oil layer floating on the upper side of the water tank to the oil tank and transports it back to the hydrolysis reactor through the oil outlet pipe. The oil layer is recovered, reducing the waste caused by the oil layer being discharged with the water layer and minimizing water washing losses.

[0009] Optionally, the oil pushing component includes a push plate, a connecting rod, and an eccentric wheel. A motor is installed on the water distribution tank. The eccentric wheel is rotatably mounted on the inner side wall of the water distribution tank and connected to the output shaft of the motor. The push plate is slidably mounted inside the water distribution tank. One end of the connecting rod is mounted on the eccentric wheel, and the end of the connecting rod away from the eccentric wheel is connected to the push plate.

[0010] By adopting the above technical solution, the motor rotates and drives the eccentric wheel to rotate. The eccentric wheel drives the connecting rod to move and then drives the push plate to slide. During the sliding process of the push plate, the oil layer on the upper side of the water tank is pushed to the oil tank. At the same time, the eccentric wheel drives the push plate to reciprocate and continuously push the oil layer, making the oil separation operation more convenient.

[0011] Optionally, the water-blocking plate includes a first water-blocking plate and a second water-blocking plate, wherein the first water-blocking plate is higher than the second water-blocking plate.

[0012] By adopting the above technical solution, the oil-containing mixed water flows from the upper side of the first baffle plate to the side of the second baffle plate. The water layer flows out through the lower outlet pipe, while the oil layer flows from the upper side of the first baffle plate to the side of the second baffle plate and finally flows to the side of the oil tank. It is then pushed to the oil tank by the push plate, resulting in a good water separation effect.

[0013] Optionally, the water distribution tank is rotatably mounted with an oil suction roller on one side of the oil tank, and a scraper is provided on one side of the water distribution tank to scrape oil from the oil suction roller.

[0014] By adopting the above technical solution, the oil suction roller pushes the oil layer to one side of the push plate and then the oil is scraped to the oil trough by the scraper, resulting in a high oil separation efficiency.

[0015] Optionally, an oil-water separation layer is provided on the outer side of the oil suction roller.

[0016] By adopting the above technical solution, when the oil suction roller rotates, it adsorbs the oil layer, and the oil-water separation layer reduces the adsorption of the water layer, resulting in a better separation effect.

[0017] Optionally, the scraping component includes a scraper and a spring. A support plate is provided inside the water distribution tank, and the spring is disposed on the support plate. The scraper is slidably installed inside the water distribution tank and connected to the spring. One side of the scraper is in contact with one side of the oil suction roller.

[0018] By adopting the above technical solution, the scraper scrapes the oil layer adsorbed on the side wall of the oil suction roller to the oil trough. When the scraper is scraping, it is pushed by the oil suction roller, and the spring pulls the scraper tight, reducing the scraper's shaking and improving the oil scraping effect on the oil suction roller.

[0019] Optionally, a filter element is provided on the upper side of the water distribution tank. The filter element includes a filter screen and a sliding box. The filter screen is inclined, and the sliding box is slidably installed on the water distribution tank and located on the lower side of the filter screen.

[0020] By adopting the above technical solution, water is distributed to the filter screen of the water distribution tank. After being filtered by the filter screen, insoluble impurities in the water are filtered out, reducing the probability of impurities flowing back to the oil tank. The impurities are retained in the sliding box, which can be removed for cleaning, making the cleaning operation relatively convenient.

[0021] Optionally, a handle is provided on the outside of the sliding box.

[0022] By adopting the above technical solution, the operation of the sliding box by pulling the handle is more convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The water layer is transported to the water distribution tank, filtered by the filter element, and flows to the water tank on the side of the oil tank through the water baffle plate. The oil pusher pushes the oil layer to the oil tank and transports it back to the hydrolysis reactor through the oil outlet pipe. The oil layer is recovered, reducing the waste caused by the oil layer being discharged with the water layer and minimizing water washing losses.

[0025] 2. After the oil layer pushed to one side by the oil suction roller is absorbed, it is scraped to the oil trough by the scraper, resulting in high oil separation efficiency;

[0026] 3. Insoluble impurities in the water are filtered out by the filter screen and remain in the sliding box. The sliding box can be removed for cleaning, which is a convenient operation. Attached Figure Description

[0035] This application discloses a water separation device for a hydrolysis reactor, referring to... Figure 1 and Figure 2 The system includes a water distribution tank 1, which is equipped with a water inlet pipe 11.

The water baffles 13 are distributed along the width direction of the water distribution tank 1. The water baffles 13 divide the inner side of the water distribution tank 1 into three water tanks 14. The water layer of the hydrolysis reactor is transported to the water distribution tank 1 through the water inlet pipe 11, filtered by the filter element 2, and flows from the upper side of the water baffles 13 to the water tank 14 on the side of the oil tank 16. Water distribution tank 1 is located on the side opposite to the water inlet pipe 11 and has an oil outlet pipe 15. Water distribution tank 1 is located on the side of oil outlet pipe 15 and has an oil tank 16. Water distribution tank 1 is located on the side of water tank 14 facing oil tank 16 and has an oil pusher 3. Water distribution tank 1 is located at the bottom of each water tank 14 and has a water outlet pipe 17. The oil pusher 3 pushes the oil layer floating on the upper side of the water tank 14 to the oil tank 16 and transports it back to the hydrolysis reactor through the oil outlet pipe 15. The oil layer is recovered and the water layer is discharged through the water outlet pipe 17, which reduces the waste caused by the oil layer being discharged with the water layer and reduces water washing loss.

[0036] Reference Figure 2 and Figure 3The filter element 2 includes a filter screen 21 and a sliding box 22. The filter screen 21 is distributed along the width of the water distribution tank 1 and is inclined. A sliding groove 18 is provided on the lower side of the filter screen 21 in the water distribution tank 1. The sliding box 22 is slidably installed in the sliding groove 18 of the water distribution tank 1. Water is distributed to the filter screen 21 of the water distribution tank 1. After being filtered by the filter screen 21, insoluble impurities in the water are filtered down, reducing the probability of impurities flowing back to the oil tank 16. The impurities are retained in the sliding box 22. The sliding box 22 can be slid out for cleaning, making the cleaning operation relatively convenient. A handle 221 is provided on the outside of the sliding box 22, making it easy to operate by pulling the sliding box 22.

[0037] Reference Figure 2 The baffle plate 13 includes a first baffle plate 131 and a second baffle plate 132. The first baffle plate 131 is located on the side facing the water inlet 12, and the second baffle plate 132 is located on the side facing the oil tank 16. The first baffle plate 131 is higher than the second baffle plate 132. Water flows from the upper side of the first baffle plate 131 to the water tank 14 on the side of the second baffle plate 132. The water layer flows out through the lower water outlet pipe 17, and the oil layer flows from the upper side of the first baffle plate 131 to the side of the second baffle plate 132, and finally flows to the side of the oil tank 16. It is pushed to the oil tank 16 by the push plate 31, and the water separation effect is good.

[0038] Reference Figure 2 and Figure 4 The oil-pushing component 3 includes a push plate 31, a connecting rod 32, and an eccentric wheel 33. A motor 34 is installed on the outer wall of the water distribution tank 1. The eccentric wheel 33 is rotatably installed on the inner wall of the water distribution tank 1 and connected to the output shaft of the motor 34. The push plate 31 is slidably installed inside the water distribution tank 1 and is distributed along the width direction of the water distribution tank 1. One end of the connecting rod 32 is rotatably installed at the eccentric wheel 33, and the end of the connecting rod 32 away from the eccentric wheel 33 is rotatably connected to the push plate 31. The motor 34 rotates, driving the eccentric wheel 33 to rotate. The eccentric wheel 33 drives the connecting rod 32 to move, which in turn drives the push plate 31 to slide. During the sliding process, the push plate 31 pushes the oil layer on the upper side of the water tank 14 to the oil tank 16. At the same time, the eccentric wheel 33 drives the push plate 31 to reciprocate, continuously pushing the oil layer, making the oil separation operation more convenient.

[0039] Reference Figure 2 and Figure 5An oil suction roller 4 is rotatably mounted on one side of the oil tank 1, located in the water distribution tank 1. The oil suction roller 4 is distributed along the width direction of the water distribution tank 1. A scraper 5 is provided on one side of the water distribution tank 1, located in the oil tank 1. After the oil layer pushed to one side by the push plate 31 by the oil suction roller 4 is absorbed, it is scraped to the oil tank 16 by the scraper 5. The scraper 5 includes a scraper 51 and a spring 52. A support plate 53 is provided inside the water distribution tank 1. The spring 52 is provided on the side of the support plate 53 facing the oil tank 16. The scraper 51 is slidably installed inside the water distribution tank 1. The scraper 51 is distributed along the width direction of the water distribution tank 1. The scraper 51 is connected to the side of the spring 52 away from the support plate 53. The upward side of the scraper 51 is in contact with the side of the oil suction roller 4. The scraper 51 scrapes the oil layer adsorbed on the side wall of the oil suction roller 4 to the oil trough 16. When the scraper 51 scrapes, it is pushed by the oil suction roller 4, and the spring 52 pulls the scraper 51 taut, reducing the swaying of the scraper 51 and improving the oil scraping effect on the oil suction roller 4. An oil-water separation layer 41 is provided on the outside of the oil suction roller 4. When the oil suction roller 4 rotates, it adsorbs the oil layer, and the oil-water separation layer 41 reduces the adsorption of the water layer, resulting in a better separation effect.

[0040] The implementation principle of the water separation device of the hydrolysis reactor in this application embodiment is as follows: the water layer of the hydrolysis reactor is put into the water separation tank 1 through the water inlet pipe 11, filtered by the filter screen 21, and then overflowed by the first water baffle plate 131 and the second water baffle plate 132. The oil layer overflows to the water tank 14 on one side, and the water layer is discharged through the water outlet pipe 17 on the lower side. The motor 34 drives the eccentric wheel 33 to rotate and push the connecting rod 32, which in turn drives the push plate 31 to slide back and forth, pushing the oil layer to the oil tank 16 on one side. The oil layer is absorbed by the oil suction roller 4, and then the oil layer on the oil suction roller 4 is scraped to the oil tank 16 by the scraper 51, and then transported back to the hydrolysis reactor through the oil outlet pipe 15.
