Description

Technical Field

[0001] The invention relates to the technical field of extraction and liquid separation, in particular to a machine vision mirror liquid separation device. Background Art

[0002] At present, extraction is also called solvent extraction or liquid-liquid extraction, also known as extraction. It is a unit operation that uses the different solubility of components in the system in the solvent to separate the mixture. In the fine chemical extraction production process, after the two reaction raw materials react in the extraction reactor, an extraction emulsification liquid separation surface appears with a high-density product at the bottom and a low-density product at the top; the operation of separating the two immiscible liquids after extraction is called liquid separation;

[0003] The mixed liquid after the reaction in the extraction reactor will be placed in the liquid separation device for liquid separation operation. The manual identification method of the emulsified liquid separation in the liquid separation sight glass will easily lead to the problem of missed identification and wrong identification, and the immersion material sensor has the problem of short life. In addition, since the liquid will contain a large number of bubbles during extraction, the presence of these bubbles will interfere with the accurate identification of the extraction emulsified liquid separation surface. During liquid separation, it is inevitable that the product liquid contains residual liquid, affecting the product quality, or the residual liquid contains product liquid. Directly discarding the residual liquid will waste the product liquid. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a machine vision mirror liquid separation device, which is provided with a bubble volume reduction control mechanism, which promotes the bursting of bubbles in the liquid by means of rapid pressurization to avoid the influence of bubbles on the recognition of the extraction emulsification liquid separation surface. During liquid separation, the product liquid located at the lower layer of the extraction emulsification liquid separation surface is first discharged through the product liquid discharge pipe, and then the residual liquid in the upper layer is discharged through the residual liquid discharge pipe. Finally, the product liquid and residual liquid remaining in the conical mixed liquid retention cylinder are pumped into the annular groove body, and after filtration, they are fully refluxed into the liquid separation cylinder to re-participate in liquid separation together with the next batch of liquid to be separated. The product liquid and residual liquid after liquid separation and discharge will not mix with each other, which is beneficial to improving product quality. At the same time, the product liquid will not be wasted, and the problems in the background technology can be effectively solved.

[0005] To achieve the above object, the present invention provides the following technical solution: a machine vision mirror liquid dispensing device, comprising:

[0006] The liquid separation container mechanism comprises a liquid separation cylinder, a cylinder cover is installed on the top of the liquid separation cylinder, a bottom ring is integrally formed and connected to the inner side of the bottom of the liquid separation cylinder, the inner side of the bottom ring is integrally formed and connected to the top of a conical mixed liquid retention cylinder, the bottom of the conical mixed liquid retention cylinder is connected to the top of a mixed liquid discharge pipe, a mixed liquid solenoid valve is installed on the mixed liquid discharge pipe, a residual liquid discharge pipe is inserted and fixedly connected to the bottom ring, a vertical limiting sleeve is inserted and fixedly connected to the conical mixed liquid retention cylinder, a product liquid discharge pipe is vertically slidably connected in the limiting sleeve, the horizontal position of the top of the product liquid discharge pipe is lower than the upper side of the bottom ring, a product liquid solenoid valve is installed at the bottom of the product liquid discharge pipe, and a sealing rubber ring is arranged in the annular groove of the inner wall of the limiting sleeve, and the sealing rubber ring is used to seal the gap between the product liquid discharge pipe and the limiting sleeve;

[0007] The top residual liquid discharge control mechanism is installed on the inner wall of the liquid separation cylinder, and the top residual liquid discharge control mechanism is located directly above the residual liquid discharge pipe;

[0008] A visual liquid dispensing control mechanism is installed on the liquid dispensing cylinder and the conical mixed liquid retaining cylinder;

[0009] The product liquid discharge pipe lifting mechanism is installed on the lower side of the bottom ring, and the product liquid discharge pipe lifting mechanism is connected to the product liquid discharge pipe.

[0010] The liquid after the reaction in the extraction reactor is sent into the liquid separation cylinder. After standing for a period of time, the product liquid is in the lower layer and the residual liquid is in the upper layer. The extraction emulsification liquid separation surface is between the product liquid and the residual liquid. Then the product liquid solenoid valve is opened, and the product liquid in the lower layer is discharged through the product liquid discharge pipe. When the extraction emulsification liquid separation surface is recognized by the visual liquid separation control mechanism, the product liquid solenoid valve is closed at this time. Some product liquid containing suspended impurities is left at the bottom of the conical mixed liquid retention cylinder. The extraction emulsification liquid separation surface is between the upper side of the bottom ring and the top of the product liquid discharge pipe. The top of the residual liquid discharge pipe is opened with the help of the overhead residual liquid discharge control mechanism, and the residual liquid is discharged through the residual liquid discharge pipe. The liquid level is already lower than the upper side of the bottom ring, and eventually a portion of the residual liquid will remain at the top of the conical mixed liquid retention cylinder. This portion of the residual liquid and the product liquid at the bottom of the conical mixed liquid retention cylinder constitute a mixed liquid. By means of the top residual liquid discharge control mechanism, the top of the residual liquid discharge pipe is closed, thereby obtaining product liquid and residual liquid. The discharged product liquid and residual liquid will not mix with each other. The mixed liquid can be left in the conical mixed liquid retention cylinder and wait to be mixed with the next batch of liquid to be separated before separation, or it can be extracted, filtered, and then sent back to the separation cylinder to wait to be mixed with the next batch of liquid to be separated before separation. With the continuous separation operation, only a small amount of mixed liquid will be left in the conical mixed liquid retention cylinder each time. However, product liquid and residual liquid that are not mixed with each other can be obtained. The top residual liquid discharge control mechanism closes the top of the residual liquid discharge pipe to prevent a part of the product liquid from being retained in the residual liquid discharge pipe as the product liquid level drops when the product liquid discharge pipe discharges the product liquid, and to prevent the residual liquid from being mixed with the product liquid retained in the residual liquid discharge pipe when the residual liquid is discharged from the residual liquid discharge pipe. The product liquid discharge pipe lifting mechanism is used to change the height of the top of the product liquid discharge pipe as needed. If the product liquid discharge pipe drops, the product liquid discharge pipe will discharge more product liquid before stopping the discharge, which is suitable for the situation where the product liquid contains less impurities, and there is no need to worry about the product liquid containing impurities being discharged through the product liquid discharge pipe. At this time, the product liquid After the product liquid and residual liquid are discharged, there will be more residual liquid retained at the top of the conical mixed liquid retention tube. If the product liquid discharge pipe rises, the product liquid discharge pipe will discharge less product liquid before stopping the discharge, which is suitable for the situation where the product liquid contains larger impurities. Since the top of the product liquid discharge pipe rises, the impurities deposited at the bottom of the conical mixed liquid retention tube are not easy to be discharged through the product liquid discharge pipe. At this time, after the product liquid and residual liquid are discharged, the residual liquid retained at the top of the conical mixed liquid retention tube will be less. No matter how the product liquid discharge pipe is raised or lowered, the horizontal position of the top of the product liquid discharge pipe must always be lower than the upper side of the bottom ring to prevent residual liquid from being discharged from the product liquid discharge pipe and mixed into the product liquid.

[0011] Furthermore, the top residual liquid discharge control mechanism includes a limit ring, a column, a discharge control plug, a discharge electric telescopic rod and a rod seat. The inner side of the bottom of the liquid separation cylinder is fixedly connected to a limit ring at a position just above the residual liquid discharge pipe. The limit ring is slidably connected to the column. The bottom end of the column is fixedly connected to the discharge control plug, and the top of the column is connected to the bottom end of the discharge electric telescopic rod. The top of the discharge electric telescopic rod is installed on the inner wall of the liquid separation cylinder through the rod seat. The rod seat is fixed to the liquid separation cylinder through the rod seat screw. The rod seat is used to install the discharge electric telescopic rod. The discharge electric telescopic rod is extended to drive the column to descend along the limit ring, so that the discharge control plug can seal the top of the residual liquid discharge pipe. The discharge electric telescopic rod is shortened to drive the column to rise along the limit ring, so that the discharge control plug can open the top of the residual liquid discharge pipe.

[0012] Furthermore, the visual liquid separation control mechanism includes guide columns, floating sleeves, guide rings, height adjustment screws, layered floating blocks, buoyancy control mounting ears, connecting rods and visual prompt blocks. The conical mixed liquid retention cylinder is fixedly connected to two vertical guide columns on both sides of the top of the limiting sleeve, and two guide rings are slidably connected to the two guide columns. The two guide rings are respectively connected to the two sides of the floating sleeve. A layered floating block is arranged in the floating sleeve. The side surface of the floating sleeve is threadedly connected with a height adjustment screw, which presses against the layered floating block. A plurality of buoyancy control mounting ears are arranged in an annular array on the outer peripheral side of the floating sleeve, and the side surface of the floating sleeve is connected to the visual prompt block through a connecting rod. The cooperation between the guide column and the floating sleeve allows the floating sleeve to move up and down, so that the visual prompt block is always close to the inner wall of the separator cylinder when it is raised or lowered, which facilitates the observation of the visual prompt block. Loosening the height adjustment screw can adjust the up and down position of the stratified floating block relative to the floating sleeve. The floating sleeve, guide ring, height adjustment screw, stratified floating block, buoyancy control mounting ear seat, connecting rod and visual prompt block constitute a stratified buoyancy body. Its comprehensive density allows it to always be at the extraction emulsification separation surface. As needed, floating blocks or counterweights can be added to the buoyancy control mounting ear seat to ensure that the stratified buoyancy body is at the extraction emulsification separation surface.

[0013] Furthermore, the visual liquid dispensing control mechanism also includes a transparent observation window, a curved frame and an industrial camera. A window slot is provided on the bottom side of the liquid dispensing cylinder. The window slot corresponds to the visual prompt block, and a transparent observation window is embedded in the window slot. A curved frame is installed at the bottom of the liquid dispensing cylinder, and an industrial camera is installed on the curved frame. The lens of the industrial camera is aligned with the bottom of the transparent observation window. The visual prompt block is close to the transparent observation window, and the industrial camera can observe the visual prompt block through the transparent observation window. For easy observation, the visual prompt block can be set to red or other bright colors. The industrial camera needs to use the visual acquisition control board in the prior art to identify the visual prompt block, and the specific identification method adopts the prior art.

[0014] When the industrial camera recognizes the visual prompt block, the extraction and emulsification liquid separation level is lower than the upper side of the bottom ring and higher than the top of the product liquid discharge pipe. At this time, it is necessary to control the product liquid solenoid valve to close and stop the discharge of the product liquid. A part of the product liquid is retained at the bottom of the conical mixed liquid retention tube. At the same time, the top of the residual liquid discharge pipe is opened with the help of the top residual liquid discharge control mechanism, and the residual liquid is discharged through the residual liquid discharge pipe. Since the top of the residual liquid discharge pipe is higher than the extraction and emulsification liquid separation level at this time, part of the residual liquid will remain in the conical mixed liquid retention tube together with the product liquid retained at the bottom of the conical mixed liquid retention tube.

[0015] Furthermore, the visual liquid dispensing control mechanism further includes a lamp holder, an illuminating lamp and an illuminating window. The side of the liquid dispensing cylinder is provided with illuminating slots at both sides of the window slot. An illuminating window is inlaid in each illuminating slot. An illuminating lamp is installed on the outside of the illuminating window through the lamp holder. The lamp holder is used to install the illuminating lamp, which illuminates the liquid dispensing cylinder through the transparent illuminating window, so as to facilitate accurate identification of the visual prompt block with the help of the industrial camera.

[0016] Furthermore, the visual liquid separation control mechanism also includes a safety sealing plug, and a safety sealing plug is installed at a position corresponding to the top of the product liquid discharge pipe at the bottom of the stratified floating block. If the industrial camera fails to timely and accurately identify the visual prompt block, a safety sealing plug is provided as a safety, and the stratified buoyancy body descends as the extraction emulsification liquid separation surface descends. When the extraction emulsification liquid separation surface is about to approach the top of the product liquid discharge pipe, causing the residual liquid to be discharged from the liquid discharge pipe, the safety sealing plug seals the liquid discharge pipe as the stratified floating block descends, which can solve the problem of liquid separation failure caused by the industrial camera failing to accurately identify the visual prompt block.

[0017] Furthermore, it also includes a mixed liquid reflux processing mechanism, which includes a reflux liquid pump, a ring-shaped groove body is fixedly sleeved on the top outer peripheral side of the liquid separation cylinder, and a plurality of reflux flow holes are opened in the ring array on the top of the liquid separation cylinder, and the bottom of the reflux flow hole is flush with the inner bottom of the ring-shaped groove body, and the bottom end of the mixed liquid discharge pipe is connected to the inlet of the reflux liquid pump through the reflux pipe 1, and the outlet of the reflux liquid pump is connected to one end of the reflux pipe 2, and the other end of the reflux pipe 2 extends into the ring-shaped groove body. After the product liquid and the residual liquid are discharged, the mixed liquid solenoid valve and the reflux liquid pump are opened, and the reflux liquid pump draws the product liquid and the residual liquid retained in the conical mixed liquid retention cylinder into the ring-shaped groove body together, and can be refluxed back to the liquid separation cylinder through the reflux flow hole, and participate in the next liquid separation together with the next batch of liquid to be separated.

[0018] Furthermore, the mixed liquid reflux treatment mechanism also includes an annular filter screen, the portion of the top peripheral side of the liquid separation cylinder located in the annular groove body is rotatably sleeved with an annular filter screen, a plurality of levers are installed in the annular array on the top of the annular filter screen, and a cleaning brush is detachably installed on the inner wall of the annular groove body, and the bristles on the cleaning brush are in contact with the outer peripheral side of the annular filter screen. The mixed liquid refluxed into the annular groove body is filtered by the annular filter screen, and the impurities contained in the mixed liquid are left on the outside of the annular filter screen, thereby preventing the impurities in the mixed liquid from affecting the next liquid separation. When the impurities left on the outside of the annular filter screen are too much and affect the filtration, the annular filter screen is rotated with the help of the lever, and the impurities on the outside of the annular filter screen are swept by the cleaning brush and collected on the side of the cleaning brush, and the collected impurities can be cleaned out from the side of the cleaning brush.

[0019] Furthermore, it also includes a bubble volume reduction control mechanism, which includes an electric telescopic rod for lifting a cone hood, two sliding sleeves are fixedly connected to the cylinder cover, and two sliding columns are vertically slidably connected in the two sliding sleeves, the top ends of the two sliding columns are respectively fixedly connected to the two ends of the arc rod, the middle part of the arc rod is fixedly connected to the top of the electric telescopic rod for lifting the cone hood, and the bottom of the electric telescopic rod for lifting the cone hood is installed on the cylinder cover, the bottom ends of the two sliding columns are fixedly connected to the top of the diversion pressurized cone hood, and the two sliding columns are connected to the liquid separation cylinder pressurizing assembly. The liquid to be separated that enters the separator from the top of the separator will fall directly onto the diversion and pressurization cone cover, and then fall to the inner wall of the separator along the edge of the diversion and pressurization cone cover due to gravity, and fall to the bottom of the separator along the inner wall of the separator, so as to avoid the liquid falling directly to the bottom of the separator to cause liquid splashing, and avoid the increase of internal bubbles caused by the splashing liquid. The reduction of bubbles is conducive to the formation of a stable and thin extraction emulsification separation surface, and the reduction of bubbles is conducive to the accurate recognition of the visual prompt block by the industrial camera.

[0020] Furthermore, the pressurizing assembly of the liquid separating cylinder includes a pressurized air pump, an air duct is provided in the middle of each sliding column, and the bottom of the air duct is connected to the lower side of the guide and pressurizing cone cover, the top of each air duct is connected to one end of the air pipe through a pipe joint, and a pressurized air pump is installed in the middle of the arc rod through a pump seat, the air outlet of the pressurized air pump is connected to the inlet of the tee, and the two outlets of the tee are connected to the other ends of the two air pipes respectively, and the inner wall of the liquid separating cylinder is fixedly connected to an inner ring at a position on the upper side of the edge of the guide and pressurizing cone cover, and an airtight rubber ring is installed in the sealing ring groove at the bottom of the inner ring.

[0021] The electric telescopic rod for lifting the cone hood is extended to drive the sliding column to move upward relative to the sliding sleeve, and the sliding column drives the diversion and pressurization cone hood to move upward, so that the upper edge of the diversion and pressurization cone hood is pressed against the airtight rubber ring on the lower side of the inner ring, so that the area where the liquid separator is located below the diversion and pressurization cone hood can form a relatively closed space. At this time, the pressurized air pump works to send air into the space through the tee, air pipe, pipe joint and airway, thereby increasing the pressure in the space, which is conducive to squeezing and bursting the bubbles in the liquid to be separated in the space, allowing it to overflow, reducing the bubbles in the liquid, and avoiding affecting the accurate recognition of the visual prompt block by the industrial camera. The electric telescopic rod for lifting the cone hood is shortened, driving the diversion and pressurization cone hood to move downward. At this time, an annular gap is left between the edge of the diversion and pressurization cone hood and the inner wall of the liquid separator, so that the liquid falling from the top of the diversion and pressurization cone hood can pass through.

[0022] Compared with the prior art, the beneficial effects of the machine vision mirror liquid dispensing device are:

[0023] 1. The liquid to be separated that enters the separator from the top of the separator will directly fall onto the diversion and pressurization cone cover, and then fall to the inner wall of the separator along the edge of the diversion and pressurization cone cover due to gravity, and then fall to the bottom of the separator along the inner wall of the separator, so as to avoid the liquid directly falling to the bottom of the separator to cause liquid splashing, and avoid the increase of internal bubbles caused by splashing liquid. The reduction of bubbles is conducive to the formation of a stable and thin extraction emulsification separation surface, and the reduction of bubbles is conducive to the accurate recognition of the visual prompt block by the industrial camera;

[0024] 2. The electric telescopic rod for lifting the cone cover extends and drives the sliding column to move upward relative to the sliding sleeve. The sliding column drives the diversion and pressurization cone cover to move upward, so that the upper edge of the diversion and pressurization cone cover is pressed against the airtight rubber ring on the lower side of the inner ring, so that the area where the liquid separation cylinder is located below the diversion and pressurization cone cover can form a relatively closed space. At this time, the pressurized air pump works to send air into the space through the tee, air pipe, pipe joint and airway, increasing the pressure of the space, which is conducive to squeezing and bursting the bubbles in the liquid to be separated in the space, allowing it to overflow, reducing the bubbles in the liquid, and avoiding affecting the accurate recognition of the visual prompt block by the industrial camera;

[0025] 3. During liquid separation, the product liquid at the lower layer of the extraction emulsification separation surface is first discharged through the product liquid discharge pipe, and then the residual liquid at the upper layer is discharged through the residual liquid discharge pipe. Finally, the product liquid and residual liquid remaining in the conical mixed liquid retention cylinder are pumped into the annular tank body, and after filtration, they are fully returned to the liquid separation cylinder to re-participate in liquid separation together with the next batch of liquid to be separated. The product liquid and residual liquid after liquid separation will not be mixed with each other, which is beneficial to improve product quality and will not waste product liquid.

[0048] The visual liquid dispensing control mechanism 3 further includes a transparent observation window 39, a curved frame 311 and an industrial camera 312. A window slot is provided on the bottom side of the liquid dispensing cylinder 11. The window slot corresponds to the visual prompt block 38, and a transparent observation window 39 is embedded in the window slot. A curved frame 311 is installed at the bottom of the liquid dispensing cylinder 11, and an industrial camera 312 is installed on the curved frame 311. The lens of the industrial camera 312 is aligned with the bottom of the transparent observation window 39. The visual prompt block 38 is close to the transparent observation window 39, and the industrial camera 312 can observe the visual prompt block 38 through the transparent observation window 39. For easy observation, the visual prompt block 38 can be set to red or other bright colors. The recognition of the visual prompt block 38 by the industrial camera 312 needs to rely on the visual acquisition control board in the prior art, and the specific recognition method adopts the prior art.

[0049] When the industrial camera 312 recognizes the visual prompt block 38, the extraction and emulsification liquid separation level is lower than the upper side of the bottom ring 12 and higher than the top of the product liquid discharge pipe 17. At this time, it is necessary to control the product liquid solenoid valve 18 to close and stop the discharge of the product liquid. A part of the product liquid is retained at the bottom of the conical mixed liquid retention tube 13. At the same time, the top of the residual liquid discharge pipe 19 is opened with the help of the top residual liquid discharge control mechanism 2, and the residual liquid is discharged through the residual liquid discharge pipe 19. Since the top of the residual liquid discharge pipe 19 is already higher than the extraction and emulsification liquid separation level at this time, part of the residual liquid and the product liquid retained at the bottom of the conical mixed liquid retention tube 13 will remain in the conical mixed liquid retention tube 13 together with the product liquid.

[0050] The visual liquid dispensing control mechanism 3 further includes a lamp holder 313, an illuminating lamp 314 and an illuminating window 310. The side of the liquid dispensing cylinder 11 is provided with illuminating slots at both sides of the window slots. An illuminating window 310 is inlaid in each illuminating slot. An illuminating lamp 314 is installed on the outside of the illuminating window 310 through the lamp holder 313. The lamp holder 313 is used to install the illuminating lamp 314. The illuminating lamp 314 illuminates the inside of the liquid dispensing cylinder 11 through the transparent illuminating window 310, which is conducive to accurately identifying the visual prompt block 38 with the help of the industrial camera 312.

[0051] The visual liquid separation control mechanism 3 also includes a safety sealing plug 315, and the safety sealing plug 315 is installed at the position of the bottom of the layered floating block 35 corresponding to the top of the product liquid discharge pipe 17. If the industrial camera 312 does not recognize the visual prompt block 38 in time and accurately, as a kind of insurance, the safety sealing plug 315 is provided, and the layered buoyancy body descends with the decline of the extraction emulsification liquid separation surface. When the extraction emulsification liquid separation surface is about to approach the top of the product liquid discharge pipe 17 and the residual liquid is about to be discharged from the liquid discharge pipe 17, the safety sealing plug 315 blocks the liquid discharge pipe 17 with the decline of the layered floating block 35, which can solve the situation that the industrial camera 312 does not accurately recognize the visual prompt block 38 and causes the liquid separation to fail.

[0052] The product liquid discharge pipe lifting mechanism 4 is installed on the lower side of the bottom ring 12 , and the product liquid discharge pipe lifting mechanism 4 is connected to the product liquid discharge pipe 17 .

[0053] The product liquid discharge pipe lifting mechanism 4 includes a base frame 41, a lead screw 42, a lead screw nut 43, a lifting control motor 44, a support rod 45, and a fixing ring 46. The lower side of the bottom ring 12 is fixedly connected to the base frame 41, and the inner side of the base frame 41 is rotatably connected to the vertical lead screw 42. The bottom end of the lead screw 42 is fixedly connected to the lifting control motor 44, and the lifting control motor 44 is installed at the bottom of the base frame 41. The lead screw 42 is matched with the lead screw nut 43. The side of the lead screw nut 43 is connected to the fixing ring 46 through the support rod 45. The fixing ring 46 is fixedly sleeved on the bottom of the product liquid discharge pipe 17. When the lifting control motor 44 works, it drives the lead screw 42 to rotate clockwise. The threaded action of the lead screw 42 and the lead screw nut 43 drives the product liquid discharge pipe 17 to descend through the support rod 45 and the fixing ring 46. When the lifting control motor 44 works, it drives the lead screw 42 to rotate counterclockwise, which can drive the product liquid discharge pipe 17 to rise.

[0054] The liquid after the reaction in the extraction reactor is sent into the liquid separation cylinder 11. After standing for a period of time, the product liquid is in the lower layer and the residual liquid is in the upper layer. The extraction emulsification liquid separation surface is between the product liquid and the residual liquid. Then the product liquid solenoid valve 18 is opened, and the product liquid in the lower layer is discharged through the product liquid discharge pipe 17. When the extraction emulsification liquid separation surface is recognized by the visual liquid separation control mechanism 3, the product liquid solenoid valve 18 is closed at this time. A part of the product liquid containing suspended impurities is left at the bottom of the conical mixed liquid retention cylinder 13. The extraction emulsification liquid separation surface is between the upper side of the bottom ring 12 and the top of the product liquid discharge pipe 17. The top of the residual liquid discharge pipe 19 is opened with the help of the overhead residual liquid discharge control mechanism 2, and the residual liquid is discharged through the residual liquid discharge pipe 19. The liquid separation surface is already lower than the upper side of the bottom ring 12, and eventually a part of the residual liquid will remain at the top of the conical mixed liquid retention tube 13. This part of the residual liquid and the product liquid at the bottom of the conical mixed liquid retention tube 13 constitute a mixed liquid. By means of the top residual liquid discharge control mechanism 2, the top of the residual liquid discharge pipe 19 is closed, thereby obtaining product liquid and residual liquid. The discharged product liquid and residual liquid will not mix with each other. The mixed liquid can be left in the conical mixed liquid retention tube 13 and wait to be mixed with the next batch of liquid to be separated before separation, or it can be extracted, filtered, and then sent back to the liquid separation tube 11 to wait to be mixed with the next batch of liquid to be separated before separation. With the continuous separation operation, only a small amount of mixed liquid will be left in the conical mixed liquid retention tube 13 each time, but The product liquid and residual liquid that are not mixed with each other can be obtained. The top residual liquid discharge control mechanism 2 closes the top of the residual liquid discharge pipe 19 to prevent a part of the product liquid from being retained in the residual liquid discharge pipe 19 as the product liquid level drops when the product liquid discharge pipe 17 discharges the product liquid, and to prevent the residual liquid from being mixed with the product liquid retained in the residual liquid discharge pipe 19 when the residual liquid is discharged from the residual liquid discharge pipe 19. The product liquid discharge pipe lifting mechanism 4 is used to change the height of the top of the product liquid discharge pipe 17 as needed. If the product liquid discharge pipe 17 drops, the product liquid discharge pipe 17 will discharge more product liquid before stopping the discharge, which is suitable for the situation where the product liquid contains less impurities, and there is no need to worry about the product liquid containing impurities being discharged through the product liquid discharge pipe 17. At this time, the product liquid and the residual liquid After all the discharges are completed, there will be a lot of residual liquid retained at the top of the conical mixed liquid retention tube 13. If the product liquid discharge pipe 17 rises, the product liquid discharge pipe 17 will discharge less product liquid before stopping the discharge, which is suitable for the situation where the product liquid contains larger impurities. Since the top of the product liquid discharge pipe 17 rises, the impurities deposited at the bottom of the conical mixed liquid retention tube 13 are not easy to be discharged through the product liquid discharge pipe 17. At this time, after the product liquid and the residual liquid are discharged, the residual liquid retained at the top of the conical mixed liquid retention tube 13 will be less. No matter how the product liquid discharge pipe 17 is raised or lowered, the horizontal position of the top of the product liquid discharge pipe 17 must always be lower than the upper side of the bottom ring 12 to prevent the residual liquid from being discharged from the product liquid discharge pipe 17 and mixed into the product liquid.

[0055] For example 2, please refer to Figures 1 to 12This embodiment provides a technical solution: a machine vision mirror liquid dispensing device. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0056] It also includes a mixed liquid reflux processing mechanism 5, which includes a reflux pipe 1 51, a reflux liquid pump 52, a reflux pipe 2 53, an annular groove body 54 and a reflux flow hole 55. The top outer peripheral side of the liquid separator 11 is fixedly sleeved with the annular groove body 54, and the top annular array of the liquid separator 11 is provided with a plurality of reflux flow holes 55. The number of the reflux flow holes 55 is selected according to needs. The bottom of the reflux flow hole 55 is flush with the inner bottom of the annular groove body 54. The bottom end of the mixed liquid discharge pipe 14 is connected to the inlet of the reflux liquid pump 52 through the reflux pipe 1 51, and the outlet of the reflux liquid pump 52 is connected to one end of the reflux pipe 2 53, and the other end of the reflux pipe 2 53 extends into the annular groove body 54. After the product liquid and the residual liquid are discharged, open the mixed liquid solenoid valve 15 and the reflux liquid pump 52. The reflux liquid pump 52 draws the product liquid and the residual liquid retained in the conical mixed liquid retention cylinder 13 into the annular groove body 54, and can flow back to the liquid separation cylinder 11 through the reflux hole 55 to participate in the next liquid separation together with the next batch of liquid to be separated.

[0057] The mixed liquid reflux treatment mechanism 5 also includes an annular filter 56, a lever 57 and a cleaning brush 510. The portion of the top outer peripheral side of the liquid separation cylinder 11 located in the annular groove body 54 is rotatably sleeved with the annular filter 56. A plurality of levers 57 are installed in an annular array on the top of the annular filter 56. The number of levers 57 is selected according to the needs. The inner wall of the annular groove body 54 is detachably installed with a cleaning brush 510. The bristles on the cleaning brush 510 are in contact with the outer peripheral side of the annular filter 56. The mixed liquid refluxed into the annular groove body 54 is filtered by the annular filter 56, and the impurities contained are left on the outside of the annular filter 56, thereby preventing the impurities in the mixed liquid from affecting the next liquid separation. When the impurities left on the outside of the annular filter 56 are too much to affect the filtration, the annular filter 56 is rotated by the lever 57, and the impurities on the outside of the annular filter 56 are swept by the cleaning brush 510 and collected on the side of the cleaning brush 510, and the collected impurities can be cleaned out from the side of the cleaning brush 510.

[0058] The mixed liquid reflux processing mechanism 5 also includes a dovetail clamp 58, a dovetail clamp strip 59, and a pipe rack 511. The inner wall of the annular groove body 54 is fixedly connected with the dovetail clamp 58, the dovetail clamp 58 is clamped with the dovetail clamp strip 59, and the dovetail clamp strip 59 is fixedly connected to the cleaning brush 510. The dovetail clamp 58 and the dovetail clamp strip 59 are used to realize the detachable installation of the cleaning brush 510. The top of the annular groove body 54 is installed with a pipe rack 511, and the pipe rack 511 is fixedly connected to the reflux pipe 2 53. The reflux pipe 2 53 is fixed with the help of the pipe rack 511, so that the reflux pipe 2 53 can be stably extended into the annular groove body 54, ensuring that the mixed liquid flowing out of the reflux pipe 2 53 stably falls into the annular groove body 54.

[0059] For example 3, please refer to Figures 1 to 12 This embodiment provides a technical solution: a machine vision mirror liquid dispensing device. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0060] It also includes a bubble volume reduction control mechanism 6, which includes a sliding sleeve 61, a sliding column 62, a diversion pressurized cone cover 63, an arc rod 66, a cone cover lifting electric telescopic rod 67 and a liquid separation cylinder pressurizing assembly. Two sliding sleeves 61 are fixedly connected to the cylinder cover 111, and two sliding columns 62 are vertically slidably connected in the two sliding sleeves 61. The top ends of the two sliding columns 62 are fixedly connected to the two ends of the arc rod 66, and the middle part of the arc rod 66 is fixedly connected to the top of the cone cover lifting electric telescopic rod 67. The bottom of the cone cover lifting electric telescopic rod 67 is installed on the cylinder cover 111, and the bottom ends of the two sliding columns 62 are fixedly connected to the top of the diversion pressurized cone cover 63, and the two sliding columns 62 are connected to the liquid separation cylinder pressurizing assembly. The liquid to be separated that enters the liquid separating cylinder 11 from the filling port 113 at the top of the liquid separating cylinder 11 will directly fall onto the diversion and pressurization conical cover 63, and then fall to the inner wall of the liquid separating cylinder 11 along the edge of the diversion and pressurization conical cover 63 due to gravity, and fall into the bottom of the liquid separating cylinder 11 along the inner wall of the liquid separating cylinder 11, so as to avoid the liquid from falling directly to the bottom of the liquid separating cylinder 11 and causing liquid splashing, and to avoid the increase of internal bubbles caused by the splashing liquid. The reduction of bubbles is conducive to the formation of a stable and thin extraction emulsification separation surface, and the reduction of bubbles is conducive to the accurate recognition of the visual prompt block 38 by the industrial camera 312.

[0061] The pressurizing assembly of the liquid dispensing cylinder includes an inner ring 64, an airtight rubber ring 65, a pipe joint 68, an air pipe 69, a tee 610, a pressurized air pump 611 and a pump seat 612. An air vent is provided in the middle of each sliding column 62, and the bottom of the air vent is communicated with the lower side of the diversion and pressurization cone cover 63. The top of each air vent is connected to one end of the air pipe 69 through a pipe joint 68. A pressurized air pump 611 is installed in the middle of the arc rod 66 through the pump seat 612. The air outlet of the pressurized air pump 611 is connected to the inlet of the tee 610. The two outlets of the tee 610 are respectively connected to the other ends of the two air pipes 69. The inner wall of the liquid dispensing cylinder 11 is fixedly connected with the inner ring 64 at a position on the upper side of the edge of the diversion and pressurization cone cover 63. An airtight rubber ring 65 is installed in the sealing ring groove at the bottom of the inner ring 64. The diameter of the bottom edge of the diversion and pressurization cone cover 63 is larger than the inner diameter of the inner ring 64.

[0062] The electric telescopic rod 67 for lifting the cone cover is extended to drive the sliding column 62 to move up relative to the sliding sleeve 61, and the sliding column 62 drives the diversion and pressurization cone cover 63 to move up, so that the upper edge of the diversion and pressurization cone cover 63 is pressed against the airtight rubber ring 65 on the lower side of the inner ring 64, so that the area below the diversion and pressurization cone cover 63 of the liquid separation cylinder 11 can form a relatively closed space. At this time, the pressurized air pump 611 works to pass air through the three-way 610, the air pipe 69, the pipe joint 68 and the airway It is sent into the space to increase the pressure of the space, which is conducive to squeezing and bursting the bubbles in the liquid to be separated in the space, allowing it to overflow, reducing the bubbles in the liquid, and avoiding affecting the accurate recognition of the visual prompt block 38 by the industrial camera 312. The cone hood lifting electric telescopic rod 67 is shortened, driving the diversion and pressurization cone hood 63 to move downward. At this time, an annular gap is left between the edge of the diversion and pressurization cone hood 63 and the inner wall of the liquid separation cylinder 11, which can allow the liquid falling from the top of the diversion and pressurization cone hood 63 to pass through.

[0063] Applying pressure during discharge can also speed up the discharge and improve the efficiency of liquid separation.

[0064] See also Figures 1 to 12 , a liquid dispensing method of a machine vision mirror liquid dispensing device, comprising the following steps:

[0065] Step 1: The liquid after the reaction in the extraction reactor enters the liquid separator 11 through the filling port 113, and the liquid falls onto the diversion and pressurization cone cover 63, and then falls to the inner wall of the liquid separator 11 along the edge of the diversion and pressurization cone cover 63 due to gravity, and falls to the bottom of the liquid separator 11 along the inner wall of the liquid separator 11, and stands for five minutes;

[0066] Step 2: The electric telescopic rod 67 for lifting the cone cover is extended to drive the sliding column 62 to move upward relative to the sliding sleeve 61, and the sliding column 62 drives the diversion and pressurization cone cover 63 to move upward, so that the upper edge of the diversion and pressurization cone cover 63 is pressed against the airtight rubber ring 65 on the lower side of the inner ring 64, so that the area where the liquid separation cylinder 11 is located below the diversion and pressurization cone cover 63 forms a closed space. At this time, the pressurized air pump 611 works to send air into the space through the tee 610, the air pipe 69, the pipe joint 68 and the airway, thereby increasing the pressure of the space, squeezing and bursting the bubbles in the liquid to be separated in the space, and allowing it to overflow, thereby reducing the bubbles in the liquid and avoiding affecting the accurate recognition of the visual prompt block 38 by the industrial camera 312;

[0067] Step 3: The electric telescopic rod 67 for lifting the conical cover is shortened, driving the diversion and pressurizing conical cover 63 to move downward. At this time, an annular gap is left between the edge of the diversion and pressurizing conical cover 63 and the inner wall of the liquid separation cylinder 11, so that the liquid falling from the top of the diversion and pressurizing conical cover 63 can pass through again;

[0068] Step 4: the product liquid is in the lower layer, the residual liquid is in the upper layer, the extraction emulsification separation surface is between the product liquid and the residual liquid, and the layered buoyancy body composed of the floating sleeve 32, the guide ring 33, the height adjustment screw 34, the layered floating block 35, the buoyancy control ear seat 36, the connecting rod 37 and the visual prompt block 38 is at the extraction emulsification separation surface;

[0069] Step 5: Open the product liquid solenoid valve 18, and the product liquid in the lower layer is discharged through the product liquid discharge pipe 17. When the industrial camera 312 recognizes the visual prompt block 38, the extraction emulsification liquid level is lower than the upper side of the bottom ring 12 and higher than the top of the product liquid discharge pipe 17. It is necessary to control the product liquid solenoid valve 18 to close and stop the discharge of the product liquid.

[0070] Step 6: The discharge electric telescopic rod 24 is shortened to drive the column 22 to rise along the limit ring 21, so that the discharge control plug 23 opens the top of the residual liquid discharge pipe 19, and the residual liquid is discharged through the residual liquid discharge pipe 19. Since the extraction emulsification liquid separation surface is lower than the upper side of the bottom ring 12, a part of the residual liquid will eventually remain at the top of the conical mixed liquid retention tube 13. This part of the residual liquid and the product liquid at the bottom of the conical mixed liquid retention tube 13 constitute a mixed liquid;

[0071] Step 7: The discharge electric telescopic rod 24 extends to drive the column 22 to descend along the limit ring 21, so that the discharge control plug 23 seals the top of the residual liquid discharge pipe 19;

[0072] Step eight, open the mixed liquid solenoid valve 15 and the reflux liquid pump 52, the reflux liquid pump 52 draws the product liquid and residual liquid retained in the conical mixed liquid retention cylinder 13 into the annular trough body 54, and is filtered by the annular filter screen 56. The impurities contained are retained on the outside of the annular filter screen 56, and the filtered mixed liquid is refluxed to the liquid separation cylinder 11 through the reflux flow hole 55, falls to the bottom along the inner wall of the liquid separation cylinder 11, and participates in the next liquid separation together with the next batch of liquid to be separated.

[0073] It is worth noting that the mixed liquid solenoid valve 15, product liquid solenoid valve 18, discharge electric telescopic rod 24, industrial camera 312, lighting lamp 314, lifting control motor 44, reflux liquid pump 52, cone cover lifting electric telescopic rod 67, and pressurized air pump 611 disclosed in the above embodiments are all controlled by an external PLC controller, and its control method adopts the method commonly used in the prior art, wherein the lifting control motor 44 adopts a servo motor.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
