Description

Technical Field

[0001] The present invention relates to the technical field of ceramic membrane separation, in particular to a membrane separation device for purifying higher carbon alcohols. Background Art

[0002] Higher alcohols refer to monohydric alcohols containing 4 or more carbon atoms. They are commonly used in the synthesis of fine chemical products such as surfactants, plasticizers, and detergents. They are also widely used in the petrochemical industry, mechanical mining, construction metallurgy, papermaking, and food. 2-propylheptanol (2-PH) is a key representative of these higher alcohols. Currently, the plasticizer dioctyl phthalate (DOP) is being gradually replaced by di(2-propylheptyl) phthalate (DPHP) due to safety concerns. As the primary synthetic raw material for DPHP, 2-PH holds broad market prospects.

[0003] Since high-carbon alcohols are mixed with some macromolecular substances, suspended matter, particulate matter and some impurities, in order to improve the purity of high-carbon alcohols, it is often necessary to filter and purify the high-carbon alcohol liquid through filtering and separation equipment, such as the Chinese patent with announcement number CN217527048U, which discloses a ceramic membrane separation device, including an upper head, an upper orifice plate, a shell, a lower orifice plate, a lower head, a plurality of ceramic membrane tubes, a screw, a cleaning disk and a driving mechanism, the upper head, the upper orifice plate, the shell, the lower orifice plate and the lower head are fixedly connected in sequence from top to bottom, the plurality of ceramic membrane tubes are evenly arranged between the upper orifice plate and the lower orifice plate, the cleaning disk thread is arranged on the screw, and the screw is fitted into the ceramic membrane tube.

[0004] However, the above scheme has the following shortcomings: in the above patent, the liquid is filtered and separated by a ceramic membrane tube, and the screw is driven to rotate by a driving mechanism, so that the cleaning disk moves up and down in the ceramic membrane tube to clean the inner wall of the ceramic membrane tube. However, when treating high-viscosity or high-carbon alcohol solutions that are prone to scaling, the filtrate located in the inner tube of the ceramic membrane will adhere to the surface of the cleaning disk. The impurities adhering to the surface of the cleaning disk will affect the cleaning effect of the cleaning disk, making it impossible for the cleaning disk to clean the inner wall of the ceramic membrane tube well. For this reason, we have introduced a membrane separation device for purifying high-carbon alcohols. Summary of the Invention

Figure 2 As shown, both ends of the traction rope 3 are fixedly connected with a ball, which is rotatably arranged in the slide rod 35, so that the traction rope 3 and the slide rod 35 are movably connected. Since the traction rope 3 is wound around the outside of the transmission wheel 48, the traction rope 3 will be driven to move during the rotation of the transmission wheel 48. The movement of the traction rope 3 pulls the slide rod 35 downward, so that the connecting disk 15 enters the inner side of the ceramic membrane tube 12.

The lower end of the ceramic membrane tube 12 is connected to the drain faucet 5, and the drain faucet 5 is fixedly installed at the lower end of the connecting seat 1. Clean water is guided into the ceramic membrane tube 12 through the liquid inlet pipe 11 to flush the cleaned impurities. The cleaned water can be discharged by opening the drain faucet 5.

[0039] Example 2:

[0040] On the basis of Example 1, in order to enable several ceramic membrane tubes 12 to be cleaned simultaneously, the first transmission mechanism includes a first gear 13, the lower end of the first gear 13 is fixedly connected to the output end of the transmission motor (not shown in the figure), the transmission motor is fixedly installed in the upper end of the connecting seat 1, and several second gears 8 are engaged with the outside of the first gear 13. The upper end of the connecting shaft 33 extends into the external environment and is fixedly connected to the second gear 8. The transmission motor drives the first gear 13 to start rotating, and the rotation of the first gear 13 drives the several second gears 8 engaged with it to rotate. The rotation of the second gear 8 drives the connecting shaft 33 to start rotating, and the rotation of the connecting shaft 33 drives the connecting disk 15 to rotate;

[0041] like Figure 2When the traction rope 3 is wound around the outer side of the transmission wheel 48, the rotation of the dual-axis motor 6 drives the transmission wheel 48 connected to its output end to rotate. Since the traction rope 3 is wound around the outer side of the transmission wheel 48, the traction rope 3 will be driven to start moving, and the traction rope 3 moves and pulls the slide bar 35 downward, so that the connection disk 15 enters the inner side of the ceramic membrane tube 12;

[0042] like Figure 8 、 Figure 9 As shown, the scraping mechanism includes a sliding box 21, which is slidably connected to the sliding cavity 24. A T-plate 20 is movably connected to the sliding box 21. One end of the T-plate 20 extends into the sliding cavity 24. The T-plate 20 is arranged in a comb-like shape at one end near the brush 18. A connecting pipe 36 is fixedly installed at one end of the sliding box 21. The connecting pipe 36 is movably connected to a plug-in pipe 37 at one end away from the sliding box 21. The plug-in pipe 37 is tapered at one end away from the connecting pipe 36. The plug-in pipe 37 is connected to the liquid guide transmission mechanism. The plug-in pipe 37 is fixedly connected to one end of the connecting pipe 36 near the connecting pipe 36. Two first T-bars 39, the second A T-shaped rod 39 is slidably connected to the first connecting cavity 40. The first connecting cavity 40 is opened in the connecting tube 36. A first spring 38 is fixedly connected to the first connecting cavity 40. The other end of the first spring 38 is fixedly connected to the first T-shaped rod 39. When the sliding box 21 moves, the plug tube 37 slides out of the T-shaped cavity 46. The first T-shaped rod 39 moves along the first connecting cavity 40, causing the first spring 38 to be compressed. When the sliding box 21 returns to its initial position, the first T-shaped rod 39 moves outward under the elastic force of the first spring 38, and the plug tube 37 is re-engaged in the T-shaped cavity 46.

[0043] like Figure 5As shown, the liquid transmission mechanism includes a T-shaped cavity 46, the T-shaped cavity 46 is connected to the sliding cavity 24, a baffle 45 is slidably connected in the T-shaped cavity 46, one end of the baffle 45 is fixedly connected to two second T-shaped rods 42, the second T-shaped rods 42 are slidably connected in the second connecting cavity 41, the second connecting cavity 41 is opened in the connecting seat 1, the outer side of the second T-shaped rod 42 is sleeved with a second spring 43, one end of the second spring 43 is fixedly connected to the second T-shaped rod 42, and the other end is fixedly connected to the second connecting cavity 41, one end of the baffle 45 is fixedly connected to the vertical plate 44, the T-shaped cavity 4 6 is connected to the liquid guide cavity 16, the liquid guide cavity 16 is provided in the connecting seat 1, the liquid guide cavity 16 is connected to the liquid storage cavity 7, the liquid storage cavity 7 is provided in the connecting seat 1, a push plate 26 is slidably connected in the liquid storage cavity 7, the push plate 26 is fixedly connected to the output end of the telescopic cylinder 10, the telescopic cylinder 10 is fixedly installed on the outside of the connecting seat 1, hydraulic oil is provided in the liquid storage cavity 7, the plug-in tube 37 enters the T-shaped cavity 46, at this time the vertical plate 44 is pushed by the plug-in tube 37 to start moving, the movement of the vertical plate 44 drives the baffle 45 to move, so that the T-shaped cavity 46 is connected to the liquid guide cavity 16;

[0044] A guide cavity 28 is provided in the connecting seat 1. One end of the guide cavity 28 is connected to the liquid guide cavity 16, and the other end is connected to the guide cavity 25. The guide cavity 25 is provided in the connecting seat 1. An L-shaped connecting plate 31 is slidably connected in the guide cavity 28. One end of the L-shaped connecting plate 31 extends into the liquid guide cavity 16. A through hole 30 is provided in the L-shaped connecting plate 31. A one-way valve 32 is also fixedly connected to the L-shaped connecting plate 31. The one-way valve 32 can guide the hydraulic oil in the guide cavity 28 into the liquid guide cavity 16, while the hydraulic oil in the liquid guide cavity 16 will not enter. The hydraulic oil flows into the guide cavity 28, to which a support spring 29 is fixedly connected. The other end of the support spring 29 is fixedly connected to the L-shaped connecting plate 31. When the two T-shaped plates 20 contact each other, the hydraulic oil that enters the liquid guide cavity 16 will push the L-shaped connecting plate 31 to move into the guide cavity 28. At this time, the support spring 29 is compressed, and the through hole 30 moves out of the liquid guide cavity 16. The L-shaped connecting plate 31 blocks the liquid guide cavity 16, and the hydraulic oil that enters the guide cavity 28 will enter the guide cavity 25.

[0045] A pull plate 23 is slidingly connected in the guide cavity 25, and a pull rope 27 is fixedly connected to one end of the pull plate 23. The pull rope 27 can be made of corrosion-resistant alloy wire.

A return spring 22 is sleeved on the outside of the pull rope 27, and one end of the return spring 22 is fixedly connected to the sliding cavity 24, and the other end is fixedly connected to the sliding box 21. The pull plate 23 located in the guide cavity 25 will be pushed by the hydraulic oil to move, and the movement of the pull plate 23 drives the pull rope 27 to move synchronously. During the movement, the pull rope 27 pulls the sliding box 21, so that the return spring 22 is compressed.

[0046] Working principle: when in use, the liquid inlet pipe 11 is connected to the discharge port of high-carbon alcohol and the clean water discharge pipe respectively, and the high-carbon alcohol liquid is guided into the ceramic membrane tube 12 through the liquid inlet pipe 11, and the high-carbon alcohol is filtered through the ceramic membrane tube 12. The filtered high-carbon alcohol liquid enters the cavity 2 and is discharged from the liquid discharge pipe 4. The filtered impurity liquid is blocked on the inner side of the ceramic membrane tube 12. When it is necessary to clean the inside of the ceramic membrane tube 12, the transmission motor and the dual-axis motor 6 are turned on at this time. The rotation of the dual-axis motor 6 drives the transmission wheel 48 connected to its output end to rotate. Since the traction rope 3 is wrapped around the outside of the transmission wheel 48, the traction rope 3 will be driven to start moving during the rotation of the transmission wheel 48;

[0047] The traction rope 3 moves and pulls the slide bar 35 downward, so that the connecting disc 15 enters the inner side of the ceramic diaphragm tube 12, and the transmission motor drives the first gear 13 to start rotating. The rotation of the first gear 13 drives several second gears 8 meshing with it to rotate, and the rotation of the second gear 8 drives the connecting shaft 33 to start rotating. The rotation of the connecting shaft 33 drives the connecting disc 15 to rotate, and the rotation of the connecting disc 15 drives several brushes 18 to rotate. The traction rope 3 pulls the connecting disc 15 to move along the inner side of the ceramic diaphragm tube 12, so that the rotating brushes 18 clean the inner side of the ceramic diaphragm tube 12. At the same time, during the cleaning process, the clean water source can be guided into the ceramic diaphragm tube 12 through the liquid inlet pipe 11 to rinse the cleaned impurities, and the cleaned water source can be discharged by opening the drain tap 5;

[0048] When the cleaning is completed, the connecting disk 15 is pulled into the yield cavity 34 by the traction rope 3, and the transmission motor is turned off at this time to stop the rotation of the connecting disk 15. Since the lower side of the positioning cavity 17 is arranged in an arc shape, when the positioning plate 19 moves to the arc position of the positioning cavity 17, the positioning plate 19 will be guided into the positioning cavity 17. When the upper end of the connecting disk 15 contacts the upper end of the yield cavity 34, the dual-axis motor 6 stops rotating and self-locks, and the telescopic cylinder 10 is opened to drive the push plate 26 connected to its output end to start moving. The push plate 26 moves along the liquid storage cavity 7 to push the hydraulic oil. At this time, the hydraulic oil will enter the T-shaped cavity 46 through the liquid guide cavity 16, and the hydraulic oil entering the T-shaped cavity 46 will enter the plug-in tube 37. The hydraulic oil entering the plug-in tube 37 will enter the sliding box 21 through the connecting pipe 36. At this time, the T-shaped plate 20 located in the sliding box 21 will be pushed outward by the hydraulic oil;

[0049] Since one end of the T-shaped plate 20 is arranged in a comb-tooth shape, when the two T-shaped plates 20 move outward synchronously and contact each other, the brush 18 located between the two T-shaped plates 20 will be clamped between the comb teeth. When the two T-shaped plates 20 contact each other, the hydraulic oil entering the liquid guide cavity 16 will push the L-shaped connecting plate 31 to move into the guide cavity 28. At this time, the support spring 29 is compressed, and the through hole 30 is moved out of the liquid guide cavity 16. The L-shaped connecting plate 31 blocks the liquid guide cavity 16, and the hydraulic oil entering the guide cavity 28 enters the guide cavity 25. At this time, the pull plate 23 located in the guide cavity 25 will be pushed by the hydraulic oil to move, and the movement of the pull plate 23 drives the pull rope 2 7 moves synchronously, and the pull rope 27 pulls the sliding box 21 during the movement, so that the return spring 22 is compressed. At this time, the sliding box 21 drives the T-shaped plate 20 to move, and the two T-shaped plates 20 move synchronously to scrape off the stains adhering to the surface of the brush 18. When the sliding box 21 moves, since one end of the plug-in tube 37 is tapered, when the sliding box 21 moves, the plug-in tube 37 will be separated from the T-shaped cavity 46. At this time, under the elastic force of the second spring 43, the baffle 45 blocks the connection between the sliding cavity 24 and the T-shaped cavity 46, and under the elastic force of the first spring 38, one end of the plug-in tube 37 will always fit with the sliding cavity 24 to prevent the hydraulic oil from flowing out.

[0050] When the connecting plate 15 moves downward again, after cleaning is completed, the push plate 26 is driven to move by the telescopic cylinder 10, so that the hydraulic oil is pumped into the liquid storage chamber 7. At this time, the hydraulic oil in the guide chamber 25 will be pumped into the guide chamber 28. Under the elastic force of the support spring 29, the L-shaped connecting plate 31 blocks the connection between the guide chamber 28 and the liquid guide chamber 16. At this time, the hydraulic oil enters the liquid guide chamber 16 through the one-way valve 32. Since the connection between the T-shaped chamber 46 and the sliding chamber 24 is blocked by the baffle 45, the hydraulic oil entering the liquid guide chamber 16 will be pumped into the liquid storage chamber 7 again. Under the elastic force of the return spring 22, the sliding box 21 moves to the right. When the plug-in tube 37 moves to the position of the T-shaped cavity 46, under the elastic force of the first spring 38, the plug-in tube 37 enters the T-shaped cavity 46. At this time, the vertical plate 44 will be pushed by the plug-in tube 37 to start moving. The movement of the vertical plate 44 drives the baffle 45 to move, so that the T-shaped cavity 46 is connected to the liquid guide cavity 16. As the push plate 26 moves, the hydraulic oil entering the sliding box 21 will be drawn into the liquid storage cavity 7. At this time, the T-shaped plate 20 is re-integrated into the sliding box 21, and the sliding box 21 returns to its original position.
