Description

[0002] The production and processing of vegetable oils are closely related to people's survival and life. With the improvement of living standards and the continuous increase in the population base, people's consumption level of vegetable oils is also increasing. Vegetable oil soap stock is an intermediate product in the vegetable oil refining process, mainly containing fatty acid salts. Acidification of vegetable oil soap stock can convert fatty acid salts into free fatty acids, which have various uses in the fields of chemical industry, oil and fat industry, etc. During the acidification process, the free fatty acids generated are insoluble in water, have a lower density than water, and will float on the water surface to form an oil layer. If oil-water separation is not performed, the product obtained is a mixture of fatty acids and other impurities, and pure fatty acids cannot be obtained for subsequent production or application.

[0003] In the prior art, after the acidification reaction of the vegetable oil soap stock, the vegetable oil soap stock mixture needs to be pumped into the oil-water separator by a material pump, and the oil and water are separated by centrifugal force. However, the vegetable oil soap stock mixture usually contains a lot of solid impurities, which will be transported to the separator together. The presence of solid impurities will interfere with the normal stratification of oil and water, and the oil and water are difficult to gather and stratify according to the density difference, thereby affecting the oil-water separation effect of the vegetable oil soap stock and reducing work efficiency.

[0015] A vegetable oil soapstock oil-water efficient separation process comprises the following steps: S1. Put the vegetable oil soap stock and acid solution into the heating reactor in turn for acidification. After the acidification is completed, let it stand for stratification, then start the regulating motor to drive the rotating rod and gear to rotate slowly, drive the rack, fixed rod and sleeve plate to move downward, and push the oil suction pipe to move downward into the oil layer; S2. When the camera captures that the oil layer is flush with the first mark, the motor adjustment is paused. The delivery pump is started to suck the oil through the oil suction pipe. When the oil layer gradually becomes flush with the second mark, the PLC controller controls the motor adjustment to resume operation and continues to drive the oil suction pipe downward, so that the oil layer is flush with the first mark again, and then the motor adjustment is paused to continue to suck the oil; S3, the oil is sprayed into the separation cover through the oil delivery pipe and the liquid inlet pipe. The transmission mechanism is started to drive the drum to rotate at high speed in the separation cover. Under the action of centrifugal force, the water phase and the oil phase in the oil will be separated and then discharged from the first liquid collecting tray and the second liquid collecting tray and the corresponding drain pipe respectively; S4. When the oil level in the separation cover is at the bottom of the first T-shaped sealing plug, the transmission mechanism is paused, and the two electric push rods are started to push the two moving blocks and the two L-shaped tubes to move, so that the first T-shaped sealing plug is moved out of the sealing hole; S5, then one end of the two L-shaped tubes is removed from the sealing hole, and at the same time, the two second T-shaped sealing plugs are driven to be inserted into the sealing hole again. When the two electric push rods are closed, one end of the left L-shaped tube is located at the inner wall of the separation cover, and one end of the right L-shaped tube is close to the drum; S6. Start the transmission mechanism again to separate the oil and water, and start the two discharge pumps at the same time. The suction in the two L-shaped pipes will suck out the water and oil respectively, and then discharge the oil and water into the two drainage pipes through the hose and the connecting pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, vegetable oil soap stock and acid solution are sequentially placed in the heating reactor for acidification treatment. After the acidification treatment is completed, the layer is allowed to stand for stratification. The regulating motor is started to drive the rotating rod and the gear to rotate slowly, drive the rack, the fixed rod and the sleeve plate to move downward, and push the oil suction pipe to move downward into the oil layer. When the camera captures that the level of the oil layer is flush with the first mark, the regulating motor is paused. The delivery pump is started to suck the oil through the oil suction pipe. As the oil layer level drops, the oil layer level gradually becomes flush with the second mark. At this time, the PLC controller controls the regulating motor to resume work, continues to drive the oil suction pipe downward, so that the oil layer level is flush with the first mark again, and then pauses the regulating motor. By adjusting the height of the oil suction pipe, the oil can be extracted layer by layer, so that the oil at the stratification can be extracted cleanly to the greatest extent, and the deposited solid impurities can be avoided from violently upwelling. Pure oil can be extracted to the greatest extent, and solid impurities can be avoided from mixing, ensuring that the quality of the oil entering the separation component is more stable.

[0017] 2. When the present invention is used, the delivery component delivers the oil to the oil delivery pipe, and then delivers the oil to the inside of the separation cover through the liquid inlet pipe. The transmission mechanism is started to drive the drum to rotate at high speed in the separation cover to form a strong centrifugal force field. Under the action of centrifugal force, the water phase and the oil phase in the oil will be separated, and finally, they will be discharged from the first liquid collecting tray and the second liquid collecting tray and the corresponding liquid drain pipe, so as to achieve the oil-water separation effect and obtain pure oil. Three blades are set at the bottom of the separation drum, which is conducive to the oil to adapt to the rapid rotation of the drum more quickly.

[0018] 3. When the present invention is used, when the oil level in the separation cover is located at the bottom of the first T-shaped sealing plug, the transmission mechanism is paused, and the two electric push rods are started to push the two moving blocks and the two L-shaped tubes to move, so that the first T-shaped sealing plug is moved out of the sealing hole, and then one end of the two L-shaped tubes is moved out of the sealing hole, and at the same time, the two second T-shaped sealing plugs are driven to be inserted into the sealing hole again. When the two electric push rods are closed, one end of the L-shaped tube on the left is located at the inner wall of the separation cover, and one end of the L-shaped tube on the right is close to the drum. The transmission mechanism is started again to separate oil and water, and the two discharge pumps are started at the same time. The suction force in the two L-shaped tubes sucks out the water and oil respectively, and then the oil and water are discharged into the two drainage pipes through the hose and the connecting pipe. Under the action of the auxiliary components, the separated oil and water can be discharged to the greatest extent, improving the oil separation effect and discharge volume, and reducing waste.

One end of the telescopic pipe 303 is fixedly connected to an oil suction pipe 303. 04, the outer surface of the oil suction pipe 304 is fixedly connected with a first mark bar 305, the outer surface of the oil suction pipe 304 is fixedly connected with a second mark bar 306 near the bottom end, the bottom of the delivery pump 301 is bolted to the top of the bottom plate 1, one end of the oil suction pipe 302 is fixedly penetrated into the interior of the heating reactor 201, the outer surface of one side of the rack 211 is fixedly installed with a fixing plate 212 near the top, the bottom of the fixing plate 212 is fixedly installed with two fixing rods 213, the bottom ends of the two fixing rods 213 are fixedly installed with a sleeve plate 214, the top of the heating reactor 201 is fixedly installed with a fixing block 215, and the outer surface of one side of the rack 211 is provided with two sliding Groove 216, a support plate 217 is fixedly installed on the outer surface of the oil suction pipe 302, two sliders 218 are fixedly installed on the outer surface of one side of the support plate 217, the outer surfaces of the two sliders 218 are movably embedded in the inside of the two slide grooves 216, the bottom ends of the two fixed rods 213 are movably penetrated into the interior of the heating reactor 201, the outer surface of the oil suction pipe 304 is fixedly installed in the inside of the sleeve plate 214 near the top, the bottom of the heating reactor 201 is fixedly installed on one side of the top of the bottom plate 1, one end of the rotating rod 209 is movably embedded in the outer surface of the fixed block 215, and the bottom of the support plate 217 is fixedly installed on the top of the heating reactor 201.

[0023] In this embodiment, when in use, the camera 205, the regulating motor 208, the delivery pump 301, the transmission mechanism 408, the discharge pump 501, the electric push rod 509 and the PLC controller 206 are electrically connected. The top of the heating reactor 201 is provided with a feed hole, the bottom is connected with a discharge pipe and a solenoid valve, and a stirrer is arranged inside. Figure 1 and Figure 3As shown. Into the heating reaction kettle 201, crushed vegetable oil soap stock, water and acid solution are placed in sequence, and the agitator is started to stir so that the vegetable oil soap stock and the acid solution can be fully mixed, and the various acids in the acid solution begin to react with components such as fatty acid salts in the soap stock, promoting the conversion of fatty acid salts into free fatty acids. After the acidification treatment is completed, an oil layer, a water layer and other solid impurities will be formed in the mixture, and then the agitator is turned off, stirring is stopped, and the precipitation stage is entered. The precipitation time is set by the PLC controller 206, so that the mixed liquid is statically layered in the heating reaction kettle 201, and the solid impurities are slowly precipitated to the bottom of the heating reaction kettle 201, and the oil layer floats above the water layer. According to the scale visual window 203, the dividing line between the oil layer and the water layer, as well as the content range of the oil layer can be seen. After the static stratification is completed, the regulating motor 208 is started to drive the rotating rod 209 and the gear 210 to rotate slowly, driving the rack 211 to move downward, passing through the moving hole 207 and gradually entering the heating reactor 201. The movement of the rack 211 will drive the fixed rod 213 and the sleeve plate 214 to move downward together, pushing the oil suction pipe 304 to move downward, and pulling the telescopic pipe 303 to unfold. At the same time, the camera 205 takes an image of the oil suction pipe 304 and transmits the captured image to the PLC controller 206 for identification and analysis. When the camera 205 captures the oil suction pipe 304 entering the oil layer, and the layer of the oil layer is flush with the position of the first mark bar 305, the regulating motor 208 will pause for a period of time, and the bottom end of the oil suction pipe 304 is inserted into the oil layer. Start the delivery pump 301, and slowly suck the oil layer into the telescopic pipe 303, the oil pumping pipe 302 and the oil delivery pipe 307 through the oil suction pipe 304, and then transport it to the separation component 4 for oil-water separation. As the oil layer level drops, the oil layer surface gradually becomes flush with the second marking bar 306, and the camera 205 transmits the captured image to the PLC controller 206 in real time. At this time, the PLC controller 206 controls the regulating motor 208 to resume working, and continues to drive the oil suction pipe 304 to move downward, so that the oil layer surface is flush with the first marking bar 305 again, and then pauses the regulating motor 208. With the cooperation of the acidifying component 2 and the conveying component 3, the effect of adjusting the height of the oil suction pipe 304 is achieved. In this way, the oil suction pipe 304 can move downward as the oil decreases, so as to extract the oil layer by layer and always suck close to the surface of the oil layer. In this way, the oil in the stratification can be extracted cleanly to the greatest extent, and the oil residue can be effectively reduced, thereby improving the oil recovery rate. It can also avoid causing violent shaking of the liquid, which causes the solid impurities deposited at the bottom to surge up, so that the oil suction pipe 304 can extract pure oil to the greatest extent, avoid the mixing of solid impurities, and ensure that the quality of the oil entering the separation component 4 is more stable. This solves the problem that after the vegetable oil soap stock undergoes an acidification reaction, the mixed liquid usually contains a lot of solid impurities, which will be transported to the separator together. The presence of solid impurities will interfere with the normal stratification of oil and water, affect the oil-water separation effect of the vegetable oil soap stock, and reduce work efficiency.

[0024] Embodiment 2: Figure 1-Figure 2 and Figure 7-Figure 9 As shown, an acidification component 2 is arranged at one side of the top of the bottom plate 1, a conveying component 3 is arranged at the center of the top of the bottom plate 1, a separation component 4 is arranged at the other side of the top of the bottom plate 1, an auxiliary component 5 is arranged on the outer surface of the separation component 4, and the separation component 4 includes a base 401, a shell 402 is fixedly installed on the front surface of the base 401, a separation cover 403 is arranged inside the shell 402, a rotating drum 404 is movably embedded inside the separation cover 403, a first liquid collecting tray 405 is fixedly installed on the top of the shell 402 and the separation cover 403, and a second liquid collecting tray 405 is fixedly installed on the top of the first liquid collecting tray 405. 6. The outer surfaces of the first liquid collecting pan 405 and the second liquid collecting pan 406 are fixedly connected with a drain pipe 407. A transmission mechanism 408 is provided on the top of the base 401. The top of the drum 404 is fixedly connected to the output end of the transmission mechanism 408. A liquid inlet pipe 409 is provided at the bottom of the shell 402. The output end of the delivery pump 301 is connected to the oil delivery pipe 307 through a flange. One end of the oil delivery pipe 307 is connected to the bottom end of the liquid inlet pipe 409 through a pipe connector. The bottom of the base 401 is fixedly installed on the other side of the top of the bottom plate 1. Two sealing holes 410 are provided on the outer surface of the separation cover 403.

[0025] In this embodiment, when in use, the delivery component 3 delivers the oil to the oil delivery pipe 307, and then delivers the oil to the inside of the separation cover 403 through the liquid inlet pipe 409. The transmission mechanism 408 is started to drive the drum 404 to rotate at high speed in the separation cover 403 to form a strong centrifugal force field. Three blades are set at the bottom of the drum 404. Driven by the blades, the oil is conducive to faster adaptation to the rapid rotation of the drum 404. After the oil is injected into the bottom of the drum 404 from the bottom liquid inlet pipe 409, under the action of centrifugal force, the oil rotates with the drum 404, and the water phase with higher density contained in the oil will be thrown to the vicinity of the inner wall of the separation cover 403 to form an outer ring; the oil phase with lower density gathers near the central axis of the drum 404 to form an inner ring, thereby achieving oil-water separation. Finally, the separated oil phase and water phase are discharged from the first liquid collecting tray 405 and the second liquid collecting tray 406 and the corresponding drain pipe 407 respectively. Under the action of the separation component 4, the oil-water separation effect is achieved to obtain pure oil.

[0026] Embodiment 3: Figure 7-Figure 9As shown, an acidification component 2 is arranged at one side of the top of the bottom plate 1, a conveying component 3 is arranged at the center of the top of the bottom plate 1, a separation component 4 is arranged at the other side of the top of the bottom plate 1, and an auxiliary component 5 is arranged on the outer surface of the separation component 4, and the auxiliary component 5 includes two discharge pumps 501, the output ends of the two discharge pumps 501 are fixedly connected with connecting pipes 502, one end of the two connecting pipes 502 is fixedly connected with one end of two drainage pipes 407 respectively, the input ends of the two discharge pumps 501 are fixedly connected with hoses 503, one end of the two hoses 503 is fixedly connected with L-shaped tubes 504, one end of the two L-shaped tubes 504 is movably penetrated into the interior of the shell 402, one end of the two L-shaped tubes 504 is provided with a first T-shaped sealing plug 505, the outer surfaces of the two L-shaped tubes 504 are fixedly connected with second T-shaped sealing plugs 506, the outer surfaces of the two second T-shaped sealing plugs 506 are movably embedded in the interior of the shell 402, and one end of the two first T-shaped sealing plugs 505 is fixedly connected to the outer surface of the two L-shaped tubes 504. Four connecting rods 507 are fixedly installed on the side outer surface, and the eight connecting rods 507 are evenly divided into two groups, one end of the two groups of connecting rods 507 are respectively fixedly installed on one end of the two L-shaped tubes 504, the outer surfaces of the two first T-shaped sealing plugs 505 are respectively in contact with the inner walls of the two sealing holes 410, and two reinforcing plates 508 are fixedly installed on the outer surface of the shell 402, and electric push rods 509 are fixedly installed on the inner walls of the two sealing holes 410, and moving blocks 510 are fixedly installed on one end of the two electric push rods 509, and one side outer surface of the two moving blocks 510 is fixedly connected to the outer surfaces of the two L-shaped tubes 504, and two sliding rods 511 are fixedly installed on the outer surfaces of the two moving blocks 510, and two moving grooves 512 are provided on the bottom surfaces of the two reinforcing plates 508, and the bottom ends of the four sliding rods 511 are respectively movably embedded in the four moving grooves 512, and the outer surfaces of the two discharge pumps 501 are mounted on the outer surface of the shell 402 through auxiliary plates.

[0027] In this embodiment, the protruding portion of the first T-shaped sealing plug 505 is embedded in the sealing hole 410, and the outer surface of one side of the first T-shaped sealing plug 505 is tightly fitted with the inner wall of the separation cover 403, so that the sealing hole 410 is in a sealed state and does not affect the subsequent oil-water separation. When the oil-water separation ends, that is, the oil in the heating reactor 201 is finished being extracted, the conveying component 3 suspends the oil conveying. At this time, the oil in the separation cover 403 continues to be separated from the oil and water and discharged outward. As the oil level in the separation cover 403 decreases, the height of the separated oil phase and water phase is not enough to reach the first liquid collecting tray 405 and the second liquid collecting tray 406. At this time, the amount of oil and water discharged from the drain pipe 407 gradually decreases. When the amount of oil and water discharged is very small, it means that the oil level in the separation cover 403 is already at the bottom of the first T-shaped sealing plug 505. The transmission mechanism 408 is paused, and the two electric push rods 509 are started. The electric push rod 509 on the left side pushes the moving block 510 and the L-shaped tube 504 on the left side to move, so that the first T-shaped sealing plug 505 on the left side is pushed out from the corresponding sealing hole 410, and one end of the L-shaped tube 504 is moved out from the sealing hole 410, and at the same time, the second T-shaped sealing plug 506 on its outer surface is inserted into the sealing hole 410, and sealed again. At this time, one end of the L-shaped tube 504 on the left side is located at the inner wall of the separation cover 403. The electric push rod 509 on the right side pushes the L-shaped tube 504 on the right side to move, and pushes the first T-shaped sealing plug 505 on the right side out of the right sealing hole 410. When one end of the L-shaped tube 504 moves toward the drum 404, it drives the second T-shaped sealing plug 506 on the right side to be inserted into the sealing hole 410 on the right side, and sealed again. At this time, the electric push rod 509 on the right side is automatically closed, and at this time, one end of the L-shaped tube 504 on the right side is close to the drum 404. The transmission mechanism 408 is started to drive the drum 404 to rotate again to separate oil and water, and the two discharge pumps 501 are started at the same time. The suction force in the two L-shaped tubes 504 overcomes the gravity of the water and oil and their position resistance in the centrifugal field, thereby sucking out the separated water and oil respectively, and then discharging the oil and water into the two drainage pipes 407 through the hose 503 and the connecting pipe 502, thereby continuing to discharge. Under the action of the auxiliary component 5, the separated oil and water can be discharged to the greatest extent, improving the oil separation effect and discharge volume, and reducing waste.

[0028] The effect and working principle achieved by the whole mechanism are as follows: crushed vegetable oil soap stock, water and acid solution are sequentially placed in the heating reaction kettle 201, and the agitator is started for stirring and acidification is performed. After the acidification is completed, an oil layer, a water layer and other solid impurities are formed in the mixture, and then the agitator is turned off, stirring is stopped, and the precipitation stage is entered. The precipitation time is set by the PLC controller 206 so that the mixed liquid is statically layered in the heating reaction kettle 201, and the solid impurities are slowly precipitated to the bottom of the heating reaction kettle 201, and the oil layer floats above the water layer. After the static layering is completed, the regulating motor 208 is started, and the rotating rod 209 and the gear 210 are driven to rotate slowly, driving the rack 211 to move downward, passing through the moving hole 207 and gradually entering the heating reaction kettle 201, and the movement of the rack 211 will drive the fixed rod 213 and the sleeve plate 214 to move downward together, pushing the oil suction pipe 304 to move downward, and pulling the telescopic pipe 303 to unfold at the same time. At the same time, the camera 205 takes an image of the oil suction pipe 304 and transmits the captured image to the PLC controller 206 for identification and analysis. When the camera 205 captures that the oil suction pipe 304 enters the oil layer and the level of the oil layer is flush with the position of the first mark bar 305, the regulating motor 208 will be suspended for a period of time, and the bottom end of the oil suction pipe 304 is inserted into the oil layer. Start the delivery pump 301, and slowly suck the oil layer into the telescopic pipe 303, the oil pumping pipe 302 and the oil delivery pipe 307 through the oil suction pipe 304, and then transport it to the separation component 4 for oil-water separation. As the oil layer liquid level drops, the oil layer level gradually becomes flush with the second mark bar 306. At this time, the PLC controller 206 controls the regulating motor 208 to resume work, and continues to drive the oil suction pipe 304 to move downward, so that the oil layer level is flush with the first mark bar 305 again, and then pauses the regulating motor 208. With the cooperation of the acidification component 2 and the conveying component 3, the height of the oil suction pipe 304 is adjusted. In this way, the oil suction pipe 304 can move downward as the oil decreases, so as to extract the oil layer by layer, and always suck close to the surface of the oil layer. In this way, the oil at the layer can be extracted cleanly to the greatest extent, effectively reducing the oil residue, thereby improving the recovery rate of the oil, and avoiding the violent shaking of the liquid, which causes the solid impurities deposited at the bottom to surge up, so that the oil suction pipe 304 can extract pure oil to the greatest extent, avoid the mixing of solid impurities, and ensure that the quality of the oil entering the separation component 4 is more stable. Start the transmission mechanism 408, drive the drum 404 to rotate at a high speed in the separation cover 403, and form a strong centrifugal field. Under the action of centrifugal force, the water phase with a higher density contained in the oil will be thrown to the vicinity of the inner wall of the separation cover 403 to form an outer ring; the oil phase with a lower density will gather near the central axis of the drum 404 to form an inner ring to achieve oil-water separation. Finally, the separated oil phase and water phase are discharged from the first liquid collecting tray 405 and the second liquid collecting tray 406 and the corresponding drain pipe 407 respectively.When the oil-water separation phase ends, the conveying assembly 3 suspends the oil delivery. At this time, the oil in the separation cover 403 continues to separate oil and water and is discharged outward. As the oil level in the separation cover 403 decreases, the height of the separated oil phase and water phase is not enough to reach the first liquid collecting tray 405 and the second liquid collecting tray 406. At this time, the amount of oil and water discharged from the drain pipe 407 gradually decreases. When the amount of oil and water discharged is very small, it means that the oil level in the separation cover 403 is already at the bottom of the first T-shaped sealing plug 505. Pause the transmission mechanism 408, start the two electric push rods 509, push the moving block 510 and the L-shaped tube 504 to move, so that the first T-shaped sealing plug 505 is moved out of the sealing hole 410, and one end of the L-shaped tube 504 enters the separation cover 403, while driving the second T-shaped sealing plug 506 to insert into the sealing hole 410 and seal again. When the two electric push rods 509 are automatically closed, one end of the left L-shaped tube 504 is located at the inner wall of the separation cover 403, and one end of the right L-shaped tube 504 is close to the drum 404. The transmission mechanism 408 is started to drive the drum 404 to rotate again to separate oil and water. At the same time, the two discharge pumps 501 are started, and the suction force in the two L-shaped tubes 504 sucks out the water and oil respectively, and then discharges the oil and water into the two discharge pipes 407 through the hose 503 and the connecting pipe 502, thereby improving the oil separation effect and discharge volume and reducing waste.
