Description

Continuous foam distillation separation and purification unit Technical Field

[0001] This invention relates to the field of distillation separation and purification, and particularly to a continuous foam distillation separation and purification apparatus. Background Technology

[0002] The continuous foam distillation separation and purification device is a high-efficiency separation equipment that combines the advantages of foam separation and distillation technologies. Through the synergistic effect of gas-liquid interface adsorption and continuous distillation, it achieves high-purity and low-cost separation of low-concentration surface-active substances or bioactive components.

[0003] After purification, the material in a continuous foam distillation separation and purification unit needs to be defoamed by a defoamer. Traditional continuous foam distillation separation and purification units typically discharge the material into a defoaming cylinder, add a defoaming agent, and then use a stirrer to agitate the mixture and achieve defoaming. In this method, the defoaming agent is usually added at a fixed location, and its dispersion throughout the material relies entirely on agitation. This results in the defoaming agent not being able to quickly diffuse throughout the material, leading to poor defoaming performance. Summary of the Invention

Detailed Implementation

[0035] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0036] As shown in Figures 1-14, the continuous foam distillation separation and purification device includes a distillation column 1, a defoaming cylinder 4, and a jetting mechanism 3 disposed at the bottom of the distillation column 1; it also includes:

[0037] A stirring assembly 10 is disposed inside a defoaming cylinder 4 and is connected to a driving mechanism 9; the driving mechanism 9 is used to drive the stirring assembly 10 to rotate.

[0038] The stirring assembly 10 includes a circular tube 1001; a plurality of uniformly distributed horizontal tubes 1004 are fixedly connected around the circular tube 1001, and the horizontal tubes 1004 have a plurality of liquid outlet holes 1005 along their length; one end of the horizontal tube 1004 is open and the other end is closed, and the open end of the horizontal tube 1004 is connected to the circular tube 1001.

[0039] Lifting mechanism 11, which is installed inside the defoaming cylinder 4 and is connected to the connecting pipe 1002 that is fixedly connected to the top of the round pipe 1001;

[0040] Conveying mechanism 12, the conveying mechanism 12 is used to convey defoamer into the circular tube 1001;

[0041] Feed assembly 6 is installed at the top inlet of defoaming cylinder 4; the feed assembly 6 includes an inner cylinder 602, an outer cylinder 601, and a telescopic pipe. A spiral channel is provided between the inner cylinder 602 and the outer cylinder 601. The inner cylinder 602 has multiple microholes 605 communicating with it, and the microholes 605 are evenly distributed along the length of the channel; the top of the outer cylinder 601 is connected to the top of the distillation column 1 through a conduit 2.

[0042] The telescopic pipe is connected to the inner cylinder 602, and the bottom end of the telescopic pipe is rotatably and sealingly connected to the top end of the connecting pipe 1002.

[0043] The distillation column 1 is divided into a main distillation column layer and a foam bed layer; a residual liquid outlet 101 and a feed inlet 102 are respectively provided on both sides of the distillation column 1.

[0044] As shown in Figure 2, the jetting mechanism 3 includes a jetting disk 302 disposed on the inner side of the bottom of the distillation column 1. A gas supply pipe 301 is fixed at the bottom of the jetting disk 302, and the gas supply pipe 301 communicates with the inner cavity of the jetting disk 302. Several evenly distributed gas holes are opened on the jetting disk 302.

[0045] The air supply pipe 301 is used to input inert gas into the inner cavity of the jet disk 302, and the inert gas is ejected from the air hole.

[0046] The material enters the distillation column 1, and after being purified by foam distillation through the sprayed inert gas, it enters the feed assembly 6 through the conduit 2, and then enters the defoaming cylinder 4 through the feed assembly 6.

[0047] The material enters the feeding assembly 6 and flows downward in the spiral channel. The spiral channel improves the flow path, and multiple micropores 605 for discharging defoamer are evenly arranged on the flow path, so that defoamer is evenly added to the defoaming cylinder 4 before the material enters it, thus achieving preliminary defoaming treatment.

[0048] After the material enters the defoaming cylinder 4, it is stirred by the stirring component 10, and the defoamer is fed into the round pipe 1001 through the conveying mechanism 12. Then, the defoamer enters the horizontal pipe 1004 through the round pipe 1001 and is discharged into the defoaming cylinder 4 through the liquid outlet 1005. As shown in Figure 7, the horizontal pipe 1004 is inside the defoaming cylinder 4. While the material is being stirred in the defoaming cylinder 4, the defoamer can also be added evenly to the material to facilitate the uniform dispersion of the defoamer in the material.

[0049] The above-mentioned dual defoaming treatment can improve the defoaming effect.

[0050] As shown in Figures 1 and 2, a heating cylinder 5 is fitted onto the conduit 2 for heating the material inside the conduit 2. Specifically, an annular cavity is formed between the heating cylinder 5 and the outer wall of the conduit 2, and a drain port and a water inlet are provided at the upper and lower parts of the heating cylinder 5. Hot water is continuously supplied into and discharged from the annular cavity through the water inlet and drain port to achieve heating.

[0051] As shown in Figures 4-6, the feeding assembly 6 further includes a spiral blade 603; the spiral blade 603 is disposed between the outer cylinder 601 and the inner cylinder 602, and the outer cylinder 601 and the inner cylinder 602 are separated into a spiral channel by the spiral blade 603. The telescopic tube of the feeding assembly 6 includes a fixed cylinder 607 fixedly installed inside the inner cylinder 602 and a movable tube 606 disposed inside the fixed cylinder 607. The bottom end of the fixed cylinder 607 is provided with a protruding ring, which is fixed to the inner wall of the bottom end of the inner cylinder 602. The top end of the movable tube 606 is fixedly sleeved with a first piston 609, and the first piston 609 is connected to the inside of the fixed cylinder 607. The bottom end of the fixed cylinder 607 is fixedly installed with a first guide ring 608, and the first guide ring 608 is slidably sleeved onto the movable tube 606.

[0052] As shown in Figure 6, the movable tube 606 is a non-circular tube. Limited by the first guide ring 608, the movable tube 606 cannot rotate. The connection between the bottom end of the movable tube 606 and the connecting tube 1002 is shown in Figure 6. The two are rotatably connected, and a sealing ring 10021 is provided at the connection point to provide a seal, achieving a rotary sealing connection. This allows the defoamer inside the circular tube 1001 to enter the movable tube 606 through the connecting tube 1002, and when the connecting tube 1002 and the circular tube 1001 rotate together, the movable tube 606 does not rotate.

[0053] A fixing seat 604 is fixed to the outer side of the bottom end of the inner cylinder 602. The fixing seat 604 is fixed to the inner wall of the bottom end of the outer cylinder 601, thereby realizing the fixed connection between the inner cylinder 602 and the outer cylinder 601.

[0054] In addition to being discharged through the outlet hole 1005, part of the defoamer in the round tube 1001 enters the movable tube 606 through the connecting tube 1002, and then enters the fixed cylinder 607 and the inner cylinder 602 through the movable tube 606, and is then discharged from the micropore 605.

[0055] As shown in Figures 7-10, the stirring assembly 10 also includes a rotating drum 1007; the top of the rotating drum 1007 is rotatably mounted to the bottom center of the defoaming cylinder 4, and a sealing element is provided between the top of the rotating drum 1007 and the bottom of the defoaming cylinder 4 to provide a seal for the rotatable mounting; a fixing plug 10071 is fixed at the bottom of the rotating drum 1007; a square shaft 1008 is elastically connected to the top of the fixing plug 10071 through a first spring 1012; the square shaft 1008 is slidably sleeved with a square hole 1010 provided at the top of the rotating drum 1007, and the top of the square shaft 1008 is fixed to the bottom of the round tube 1001.

[0056] A corrugated hose 1006 is provided between the circular tube 1001 and the rotating drum 1007, and the top and bottom ends of the corrugated hose 1006 are fixedly sleeved to the bottom end of the circular tube 1001 and the top end of the rotating drum 1007, respectively. The bottom end of the circular tube 1001 is provided with a first connecting hole 1009, and the circular tube 1001 is connected to the corrugated hose 1006 through the first connecting hole 1009. The top end of the rotating drum 1007 is provided with a second connecting hole 1011, and the rotating drum 1007 is connected to the corrugated hose 1006 through the second connecting hole 1011. A plurality of stirring blades 1003 are fixedly installed on the circular tube 1001, and the plurality of stirring blades 1003 are respectively installed on a plurality of horizontal tubes 1004.

[0057] As shown in Figures 4-5, the lifting mechanism 11 includes a side frame 1101 fixedly installed on one side wall of the connecting pipe 1002 and a support inclined ring 1102 fixedly installed inside the defoaming cylinder 4. The side frame 1101 is bent downward at one end away from the connecting pipe 1002, and a concave hole is provided at the bent end of the side frame 1101. A ball bearing 1104 is provided in the concave hole. A retaining ring 1103 is fixed at the bent end of the side frame 1101. The inner diameter of the retaining ring 1103 is smaller than the diameter of the ball bearing 1104 to block the ball bearing 1104 and prevent the ball bearing 1104 from detaching from the concave hole. The ball bearing 1104 is in contact with the top surface of the support inclined ring 1102.

[0058] When the stirring assembly 10 is driven to rotate, the side frame 1101 rotates with it. The side frame 1101 travels on the top surface of the support ring 1102 via the ball bearings 1104. As shown in Figure 4, the support ring 1102 is higher on the left and lower on the right. When the side frame 1101 moves from the high position to the low position on the support ring 1102, the overall height of the stirring assembly 10 decreases. Conversely, when the side frame 1101 moves from the low position to the high position, the overall height of the stirring assembly 10 increases.

[0059] With the above design, when the stirring component 10 rotates continuously, the stirring component 10 moves back and forth, which improves the stirring effect and facilitates the injection of defoamer between the vertically adjacent horizontal pipes 1004, so as to improve the effect of the defoamer being dispersed into the defoaming cylinder 4.

[0060] The connecting pipe 1002 of the stirring assembly 10 is connected to the feeding assembly 6 through a telescopic pipe fitting. When the stirring assembly 10 moves up and down, the telescopic pipe fitting extends and retracts accordingly.

[0061] The movable tube 606 of the telescopic fitting moves up and down together with the connecting tube 1002, and the movable tube 606 drives the first piston 609 to slide inside the fixed cylinder 607 to achieve telescopic movement.

[0062] When the stirring assembly 10 moves up and down, the round tube 1001 and the square shaft 1008 move, the square shaft 1008 slides with the square hole 1010, and the rotating drum 1007 does not move up and down.

[0063] By setting the corrugated hose 1006, when the round tube 1001 moves up and down, the corrugated hose 1006 can be stretched or compressed without affecting the up and down movement of the round tube 1001.

[0064] As shown in Figures 7 and 8, a support frame 8 is fixed to the bottom of the defoaming cylinder 4; a bracket 801 is fixed on the support frame 8, and the driving mechanism 9 is installed on the bracket 801; the driving mechanism 9 includes a motor 901 fixedly installed on the bracket 801, a first pulley 902 is installed on the output shaft of the motor 901, a second pulley 903 is fixedly sleeved on the rotating cylinder 1007, and a belt 904 is wound between the first pulley 902 and the second pulley 903.

[0065] The motor 901 drives the first pulley 902 to rotate, and the belt 904 drives the second pulley 903 and the rotating drum 1007 to rotate. The rotating drum 1007 drives the square shaft 1008 and the round tube 1001 to rotate together.

[0066] As shown in Figure 14, the rotating cylinder 1007 passes through the circular hole opened on the bracket 801, and two baffles 10072 are fixedly sleeved on the rotating cylinder 1007, and the two baffles 10072 are respectively attached to the top surface and the bottom surface of the bracket 801.

[0067] As shown in Figures 9, 11, and 12, the conveying mechanism 12 is connected to the bottom of the rotating drum 1007; the conveying mechanism 12 includes a ring 1201 and multiple conveying parts; the ring 1201 is fixedly installed to the bottom of the bracket 801, and multiple protrusions 1202 arranged in a ring array are fixedly installed on the inner ring of the ring 1201, and a groove is formed between each pair of adjacent protrusions 1202, and the groove wall and the protrusion 1202 wall form a ring-shaped traveling surface; the multiple conveying parts are arranged in a ring array at the bottom end of the rotating drum 1007, and the end of the conveying part away from the rotating drum 1007 abuts against the traveling surface.

[0068] As shown in Figures 11-12, the conveying unit includes a conveying cylinder 1203 fixedly installed on the outer wall of the rotating drum 1007. A second piston 1206 is connected inside the conveying cylinder 1203. The side of the second piston 1206 and the inner wall of the conveying cylinder 1203 form a cylindrical cavity. A first one-way valve 1207 is installed at one end of the conveying cylinder 1203. One end of the first one-way valve 1207 communicates with the cylindrical cavity, and the other end of the first one-way valve 1207 extends into the rotating drum 1007. A movable column 1204 is fixed to the second piston 1206. The conveying... A second guide ring 1209 is fixed to the end of the cylinder 1203. The movable column 1204 is slidably sleeved with the second guide ring 1209. A second spring 1210 is sleeved on the movable column 1204. The movable column 1204 is elastically connected to the second guide ring 1209 through the second spring 1210. A roller 1205 is rotatably mounted on the end of the movable column 1204 away from the second piston 1206, and the roller 1205 is in contact with the traveling surface. A second one-way valve 1208 is fixed to the bottom of the conveying cylinder 1203, and one end of the second one-way valve 1208 extends into the cylinder cavity.

[0069] Below the conveying mechanism 12, there is a defoamer storage tank 7. The bottom end of the second one-way valve 1208 is fixedly connected to a suction pipe 1211, which extends into the defoamer storage tank 7.

[0070] The conveying mechanism 12 is used to convey defoamer into the rotating drum 1007. The defoamer input into the rotating drum 1007 passes through the second connecting hole 1011, the corrugated hose 1006, and the first connecting hole 1009 in sequence before entering the round tube 1001.

[0071] The conveying mechanism 12 operates as follows: When the stirring assembly 10 rotates, multiple conveying sections on the rotating drum 1007 rotate together. The rollers 1205 of the conveying section move from the boss 1202 to the groove. Through the elastic force of the second spring 1210, the movable column 1204 drives the second piston 1206 to move together, increasing the volume of the drum cavity. The drum cavity draws defoamer from the defoamer storage tank 7 through the second one-way valve 1208 and the suction pipe 1211. Meanwhile, the rollers 1205 of the conveying section move from the groove to the boss 1202, squeezing and causing the movable column 1204 and the second piston 1206 to move. The second piston 1206 pushes the defoamer in the drum cavity, allowing the defoamer to enter the rotating drum 1007 through the first one-way valve 1207.

[0072] With the above design, when the stirring assembly 10 is in a continuous state, defoamer can be automatically delivered into the rotating drum 1007.

It also includes an air extraction mechanism 13, which includes an air cylinder 1301 fixedly installed above the defoaming cylinder 4. A third piston 1303 is connected internally to the air cylinder 1301. A vertical pipe 1304 is fixedly installed in the middle of the third piston 1303. A connecting rod 1306 is fixed to the bottom side wall of the vertical pipe 1304, and the connecting rod 1306 is fixed to the movable pipe 606. A fourth one-way valve 1305 is installed at the bottom end of the vertical pipe 1304, and a third one-way valve 1302 is installed at the top of the air cylinder 1301.

[0076] The air extraction mechanism 13 is used to draw negative pressure inside the defoaming cylinder 4. Compared with the first embodiment, it can reduce the air pressure on the liquid surface of the material inside the defoaming cylinder 4, making it easier for the material in the conduit 2 to be transported into the defoaming cylinder 4. At the same time, it reduces the air pressure inside the defoaming cylinder 4, making it easier for the material to be defoamed.

[0077] The specific operation of the suction mechanism 13 is as follows: when the stirring assembly 10 rotates continuously, the lifting mechanism 11 drives the round pipe 1001 and the connecting pipe 1002 to move up and down together. The connecting pipe 1002 drives the vertical pipe 1304 and the third piston 1303 to move up and down together through the connecting rod 1306. When the third piston 1303 moves downward, the air cylinder 1301 is sucked in, and the gas in the defoaming cylinder 4 enters the air cylinder 1301 through the fourth one-way valve 1305 and the vertical pipe 1304. When the third piston 1303 moves upward, the third piston 1303 pushes the gas in the air cylinder 1301, so that the gas is discharged out of the defoaming cylinder 4 through the third one-way valve 1302.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
