Description

Technical Field

[0001] The invention relates to the technical field of fatty acid production, and in particular to continuous acidification equipment and an acidification process for fatty acid production. Background Art

[0002] Fatty acids are organic substances with long aliphatic hydrocarbon chains containing a carboxyl group at one end. They are the simplest type of fat and can be divided into saturated fatty acids and unsaturated fatty acids. They participate in many physiological processes in organisms, such as energy storage and the formation of biological membranes. They can be used in industry to produce many products such as soaps, lubricants, and coatings.

[0003] In a Chinese patent with application number CN201820872281.3, a fatty acid continuous acidification tank is disclosed. This device realizes two process effects of acidification and separation. The reaction chamber and the separation chamber are separated by a partition to ensure the stability of the separation of the fatty acid phase and the water phase; the waste acid guide pipe is arranged in a U shape to ensure that the fatty acid phase and the water phase are separated by gravity under pressureless conditions.

[0004] In the above patent, for the production of fatty acids, the general method is to pour all the materials, acidulants and water into a container for stirring reaction.

[0019] Another technical solution proposed by the present invention is an acidification process for continuous acidification for fatty acid production, comprising the following steps:

[0020] S1: After the required water source is added into the acidification tank through the water inlet, the water source will be located on the upper surface of the temporary storage tank because the electric telescopic plate blocks the drain groove. Then, the materials for making fatty acids are added into the hopper, and the acidulant needs to be added into the liquid storage tank. Then, the dual-axis motor can be started to start stirring the stirring rod;

[0021] S2: As the dual-axis motor starts, one set of small gears will drive the large gear to rotate, and the rotating large gear will drive the disc and the clamping column to rotate together. One set of rotating clamping columns will drive the T block to move, and the T block will drive the cross plate to move to one end until the clamping column and the T block are separated. At this time, the other set of clamping columns will contact one end of the V plate, causing the V plate to rotate counterclockwise, thereby driving the cross plate to move to the other end, allowing the cross plate to move back and forth;

[0022] S3: As the horizontal plate reciprocates, the roller will reciprocate to squeeze the inclined plate and the pressure plate, and the moving inclined plate and the pressure plate will also move together with the fixed rod and the push plate, so that the push plate squeezes the acidifier inside the liquid storage tank into the liquid outlet pipe, and finally flows into the water source that has been added in advance through the liquid outlet pipe. Since the C-shaped plate is fixedly connected to the horizontal plate and the C-shaped plate moves inside the fine groove, the reciprocating C-shaped plate allows the inclined block to reciprocate along the inclined groove, so that the material inside the hopper is discharged together with the acidifier. At this time, the acidifier and the material will be added to the water source for mixing and stirring. When the horizontal plate reciprocates, the lever will swing back and forth with the central column as the center, thereby driving the circular frame to rise and fall back and forth, further increasing the speed of stirring and mixing;

[0023] S4: When the liquid mixing is completed, the dual-axis motor is stopped, and the electric telescopic plate is turned on to allow the liquid to enter the liquid storage chamber, and then discharged to the surface of the filter membrane through the quantitative valve. At this time, the speed of the liquid descent will decrease, and the total amount of liquid will also decrease, which can prevent the impact caused by the liquid discharge from causing the filter membrane to rupture. When all the liquid enters the liquid storage chamber, the next round of mixing can be carried out, and the liquid that falls on the surface of the filter membrane will be filtered, and the activated carbon, sodium fatty acid, sodium sulfate crystals and other substances in the liquid will be filtered, so that only fatty acids fall to the cone mouth, and the scraper will slide out the impurities on the surface of the filter membrane, and finally discharge from the sewage outlet.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention provides a continuous acidification device and an acidification process for fatty acid production. When fatty acids need to be produced, materials are added into a hopper. At this time, a baffle blocks the materials in the hopper. Then, water is added into an acidification tank through a water inlet. A double-shaft motor is started to rotate a disc with a pinion. The rotating disc allows a transverse plate to reciprocate through a clamping column on the surface. The reciprocating transverse plate reciprocates to squeeze a pressing plate, allowing the pressing plate to discharge the liquid in a liquid storage tank with a fixed rod and a push plate. The baffle also reciprocates due to an inclined groove and an inclined block, allowing the materials in the hopper to be discharged. At this time, the double-shaft motor stirs the liquid. While the transverse plate reciprocates, a lever also reciprocates to swing, causing a circular frame to reciprocate. The reciprocating movement of the transverse plate drives the quantitative discharge of materials and an acidulant. The reciprocating reciprocating circular frame is used to improve the purity and quality of the fatty acids. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the electric telescopic plate 53 is started to move the electric telescopic plate 53 to the inside of the storage groove 52, so that the liquid enters the liquid storage chamber 54. Finally, the liquid in the liquid storage chamber 54 can be quantitatively dropped onto the surface of the filter component 4 through the quantitative valve.

[0047] The filter assembly 4 includes a fixed frame 44 fixedly mounted on the inner wall of the acidification box 1, a side box 41 fixedly mounted on one side of the acidification box 1, an electric telescopic rod 42 fixedly mounted on the inner wall of the side box 41, a scraper 43 fixedly mounted on one end of the electric telescopic rod 42, the fixed frame 44 is located below the temporary storage box 5, a filter membrane 47 fixedly mounted on the inner wall of the fixed frame 44, the upper surfaces of the fixed frame 44 and the filter membrane 47 are both in contact with the lower surface of the scraper 43, a magnet A45 embedded on one side of the fixed frame 44, and a flip plate 46 arranged inside the sewage outlet 12, and the magnet A45 is opposite to the flip plate 46;

[0048] A magnet B461 is fixedly installed on one side of the flip plate 46 close to the magnet A45, and the magnet B461 is magnetically attracted to the magnet A45. A tension spring 462 is fixedly installed on the other side of the flip plate 46, and one end of the tension spring 462 is fixedly connected to the top of the sewage outlet 12. A long rod 463 is provided at one end of the flip plate 46, and both ends of the long rod 463 are fixedly connected to the inner wall of the sewage outlet 12. The magnets A45 and the magnet B461 can ensure that the water falling on the surface of the filter membrane 47 will not flow out, and then the activated carbon, sodium fatty acid, sodium sulfate crystals and other substances in the liquid are isolated by the filter membrane 47, and the fatty acids are allowed to fall into the inside of the cone mouth 13 and then discharged from the liquid discharge pipe 14. Finally, the substances on the surface of the filter membrane 47 are scraped off by the scraper 43, and finally the flip plate 46 is pushed open to discharge the substances.

[0049] Another technical solution proposed by the present invention is an acidification process for continuous acidification for fatty acid production, comprising the following steps:

[0050] S1: After the required water source is added into the acidification tank 1 through the water inlet 17, the water source will be located on the upper surface of the temporary storage tank 5 because the electric telescopic plate 53 blocks the drain groove 51. Then, the material for making fatty acids is added into the hopper 3, and the acidulant needs to be added into the liquid storage tank 22. Then, the dual-axis motor 26 can be started to allow the stirring rod 253 to start stirring;

[0051] S2: With the start of the dual-axis motor 26, one group of small gears 261 will drive the large gear 2413 to rotate, and the rotating large gear 2413 will drive the disc 241 and the clamping column 2412 to rotate together, and one group of rotating clamping columns 2412 will drive the T block 2432 to rotate, and the T block 2432 will drive the horizontal plate 243 to move to one end until the clamping column 2412 and the T block 2432 are separated, at which time the other group of clamping columns 2412 will contact the V plate 2436, causing the V plate 2436 to rotate counterclockwise, thereby driving the horizontal plate 243 to move to the other end, and causing the horizontal plate 243 to move back and forth;

[0052] S3: With the reciprocating movement of the horizontal plate 243, the roller 2435 will reciprocate and squeeze the inclined plate 224 and the pressure plate 225. The moving inclined plate 224 and the pressure plate 225 will also move together with the fixed rod 227 and the push plate 228, so that the push plate 228 squeezes the acidifier inside the liquid storage tank 22 into the inside of the liquid outlet pipe 223, and finally flows into the water source added in advance through the liquid outlet pipe 223. Since the C-shaped plate 242 is fixedly connected to the horizontal plate 243, and the C-shaped plate 242 is located inside the fine groove 212 and moves, the reciprocating C-shaped plate 242 allows the inclined block to reciprocate along the inclined groove 2421, so that the material inside the hopper 3 is discharged together with the acidifier. At this time, the acidifier and the material will be added to the water source for mixing and stirring. When the horizontal plate 243 reciprocates, the lever 2442 will swing back and forth with the central column 2441 as the center, thereby driving the circular frame 231 to rise and fall back and forth, further improving the stirring and mixing speed;

[0053] S4: When the liquid mixing is completed, the dual-axis motor 26 is stopped, and the electric telescopic plate 53 is turned on to allow the liquid to enter the liquid storage chamber 54, and then discharged to the surface of the filter membrane 47 through the quantitative valve. At this time, the speed at which the liquid descends will decrease, and the total amount of the liquid will also decrease, which can prevent the filter membrane 47 from rupturing. After all the liquid enters the liquid storage chamber 54, the next round of mixing can be carried out, and the liquid that falls on the surface of the filter membrane 47 will be filtered, and the activated carbon, sodium fatty acid, sodium sulfate crystals and other substances in the liquid will be filtered, so that only the fatty acid falls to the cone mouth 13, and the scraper 43 will slide out the impurities on the surface of the filter membrane 47, and finally discharged from the sewage outlet 12.

[0054] Specifically, when fatty acids need to be produced, materials are added into the hopper 3, acidulant is added into the liquid storage tank 22, and then water is added into the acidification tank 1. At this time, the materials in the hopper 3 will be blocked by the baffle 2422. At this time, the dual-axis motor 26 is started to rotate the drive shaft 251, and the drive shaft 251 with the small gear 261 will drive the large gear 2413 to rotate together. The rotating large gear 2413 will drive the disc 241 and the clamping column 2412 to rotate together. At this time, one group of clamping columns 2412 will contact one side of the T block 2432, so that the T block 2432 moves to one end with the cross plate 243. When the clamping column 2412 is separated from the T block 2432, the other group of clamping columns 2412 will contact the V plate 2 436, thereby rotating the V-plate 2436 counterclockwise. Since a short column 2431 is provided inside the vertical slot 2438 at the other end of the V-plate 2436, and the short column 2431 is fixedly connected to the cross plate 243, the counterclockwise rotating V-plate 2436 will move the cross plate 243 to the other end. When the other set of clamping columns 2412 are separated from one end of the V-plate 2436, they will contact the T block 2432, allowing the T block 2432 to continue to move the cross plate 243. At this time, the rotation of the disc 241 drives the reciprocating movement of the cross plate 243. Due to the reciprocating movement of the cross plate 243, the roller 2435 located on one side of the cross plate 243 will reciprocately squeeze the pressure plate 225 and the inclined plate 224. Since a spring rod 222 is fixedly installed on one side of the inclined plate 224, the squeezed The pressing plate 225 will move with the fixed rod 227, so that the fixed rod 227 and the push plate 228 squeeze the acidifier in the liquid storage tank 22 into the liquid outlet pipe 223, so that the acidifier in the liquid outlet pipe 223 flows into the acidification tank 1. When the roller 2435 moves to the inclined plate 224, the spring rod 222 will reset the inclined plate 224 and the pressing plate 225 to prepare for the next squeezing. At the same time as the liquid storage tank 22 is squeezed, the baffle 2422 will also reciprocate due to the inclined block and the inclined groove 2421, so that the material in the hopper 3 is also indirectly discharged into the acidification tank 1. At this time, the material and the acidifier will be indirectly discharged to ensure that the material and the acidifier are fully and evenly mixed and reacted. When the liquid is stirred, the lever 2442 located in the bottom groove 2433 will swing back and forth with the central column 2441 as the center. Since the T-disc 2443 at one end of the lever 2442 is located in the T-shaped arc groove 234 and the circular frame 231 can only move vertically, the reciprocating horizontal plate 243 will also drive the circular frame 231 to rise and fall back and forth, further improving the stirring efficiency. When the liquid is stirred, the electric telescopic plate 53 is opened to allow the liquid to enter the liquid storage chamber 54, and then the quantitative valve inside the discharge pipe 57 is used to indirectly allow the liquid to fall onto the surface of the filter membrane 47 for filtration. The indirect discharge of the liquid can prevent the impact force of the liquid from tearing the filter membrane 47. After all the liquid enters the liquid storage chamber 54, the liquid can be stirred again.When the liquid production is completed, the electric telescopic rod 42 is started, and the electric telescopic rod 42 and the scraper 43 are used to scrape the impurities isolated from the surface of the filter membrane 47. Finally, the scraper 43 pushes the flip plate 46 open, and the impurities are discharged through the sewage outlet 12. The reciprocating movement of the horizontal plate 243 drives the quantitative discharge of the material and the acidifier, and the reciprocating lifting and lowering circular frame 231 is equipped, thereby improving the purity and quality of the fatty acid.

An acidification process of the continuous acidification equipment for fatty acid production according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: After the required water source is added into the acidification tank (1) through the water inlet (17), the drain groove (51) is blocked by the electric telescopic plate (53), and the water source is located on the upper surface of the temporary storage tank (5). Then, the material for making fatty acids is added into the hopper (3), and the acidulant is added into the liquid storage tank (22). Then, the dual-axis motor (26) can be started to start stirring the stirring rod (253); S2: As the dual-axis motor (26) is started, the small gear (261) drives the large gear (2413) to rotate, and the rotating large gear (2413) drives the disk (241) and the clamping column (2412) to rotate together, and one set of rotating clamping columns (2412) drives the T block (2432) to move, and the T block (2432) drives the horizontal plate (243) to move to one end until the clamping column (2412) and the T block (2432) are separated, at which time another set of clamping columns (2412) contacts one end of the V plate (2436), causing the V plate (2436) to rotate counterclockwise, thereby driving the horizontal plate (243) to move to the other end, causing the horizontal plate (243) to move back and forth; S3: As the horizontal plate (243) moves back and forth, the roller (2435) will reciprocate and squeeze the inclined plate (224) and the pressure plate (225). The moving inclined plate (224) and the pressure plate (225) will also move together with the fixed rod (227) and the push plate (228), so that the push plate (228) can squeeze the acidifier inside the liquid storage tank (22) into the liquid outlet pipe (223), and finally flow through the liquid outlet pipe (223) to the water source that has been added in advance. Due to the fixed connection between the C-shaped plate (242) and the horizontal plate (243), , and the C-shaped plate (242) is located inside the narrow groove (212) and moves, so the reciprocating C-shaped plate (242) allows the inclined block to reciprocate along the inclined groove (2421), so that the material inside the hopper (3) is discharged together with the acidifier.

At this time, the speed of the liquid falling will be reduced, and the total amount of the liquid will also be reduced, which can prevent the problem of the filter membrane (47) being broken due to the impact generated when the liquid is discharged. When all the liquid enters the liquid storage chamber (54), the next round of mixing can be carried out, and the liquid that falls on the surface of the filter membrane (47) will be filtered to filter the activated carbon, sodium fatty acid, sodium sulfate crystals and other substances in the liquid, so that only the fatty acid falls to the cone mouth (13), and the scraper (43) will slide out the impurities on the surface of the filter membrane (47), and finally discharged from the sewage outlet (12).
