Abstract
Description
Technical Field
[0001] This invention relates to the field of emulsion treatment, and more particularly to a high-efficiency oil-water separation device for CNC lathes. Background Technology
[0002] Emulsion is a high-performance semi-synthetic metalworking fluid with a long service life, completely unaffected by oil leaks or contamination. It is best prepared with soft water. The emulsion uses a chlorine-free, specially formulated solution to address various problems encountered during the machining of aluminum and its alloys, such as chip adhesion, tool wear, poor workpiece surface finish, and surface contamination. It can be applied to all operations, including reaming. The emulsion also effectively prevents rust and chemical corrosion of the workpiece and effectively prevents bacterial contamination. Large quantities of emulsion are used in industrial production. After a period of use, the emulsion will become mixed with a significant amount of oil. To reuse the emulsion, it needs to be degreased.
[0003] Patent document CN202122839266.3 discloses an emulsion oil removal device, including a support frame, a drive wheel, a driven wheel, a conveyor belt, and an oil guide groove. Several oil filter grooves are distributed on the conveyor belt. Each oil filter groove includes a back plate. The upper part of the back plate is hinged to the conveyor belt and located on the outside of the conveyor belt. A support block is fixedly connected to the middle of the back plate. The support block supports the outer ring of the conveyor belt and the upper part of the back plate is inclined towards the hinge point between the back plate and the conveyor belt. A tank structure and a funnel structure are provided at the lower part of the back plate. The inlet of the tank structure and the inlet of the funnel structure both face the upper part of the back plate. The outlet of the funnel structure is located at the bottom of the tank structure. The volume of the tank structure is smaller than the volume of the funnel structure.
[0004] However, in actual use, the emulsion itself is prone to deterioration, and its properties will change after long-term use, affecting its performance. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a detection mechanism and a replenishment mechanism to detect the pH value of the emulsion in stages. The pH value reflects the degree of deterioration of the emulsion, and the deteriorated emulsion is discharged from the device while being replaced with freshly mixed emulsion. This ensures that the emulsion is always in a relatively healthy state, extends the emulsion's lifespan, and solves the technical problem that emulsions are prone to deterioration, and their performance deteriorates over long-term use, affecting normal use.

[0013] Preferably, the detection assembly includes multiple sets of isolation tubes connected to the first centrifuge and having discharge pipes and connecting pipes at both ends respectively, a detection element disposed above the isolation tubes, and a control element disposed below the isolation tubes and cooperating with the detection element. The detection element includes a pH meter and a linear motor for fixing the pH meter and driving the pH meter to move between the isolation tubes.
[0014] It also includes a detection hole located on the upper part of the isolation tube, multiple cover plates located inside the detection hole and hinged to the side wall of the detection hole, a second telescopic cylinder that is fixedly connected to the telescopic rod and pH meter and fixedly mounted on the slider of the linear motor, a stirring shaft located inside the isolation tube, and a first motor that drives the stirring shaft to rotate and is fixedly mounted on the isolation tube.
[0015] Preferably, the control component includes a control rod slidably connected below the isolation pipe, an electric cylinder that drives the control rod to move back and forth, and a first contact switch fixed at both ends of the control rod. The contact switch controls the opening and closing of the solenoid valve located inside the discharge pipe and the connecting pipe.
[0016] Preferably, the cleaning assembly includes a cleaning component disposed inside the isolation tube and a contact component disposed outside the isolation tube to control the operation of the cleaning component. The cleaning component includes a magnetically pleasing metal scraper disposed inside the isolation tube with its edge in contact with the inner wall of the isolation tube and its center not in contact with the stirring shaft; a threaded rod whose two ends are fixedly connected to both ends of the isolation tube and threadedly connected to the scraper; a second motor that drives the threaded rod to rotate and is installed outside the isolation tube; and a magnetic baffle that is slidably connected to the stirring shaft.
[0017] Preferably, the contact element includes a push rod fixedly connected to one end of the control rod, a movable block slidably connected to the isolation tube and provided above it for controlling the second motor contact switch, and a lever hinged at the lower end to the push rod and at the upper end to the movable block.

[0021] The beneficial effects of this invention are:
[0022] (1) In this invention, by setting up a filtration mechanism, the iron filings mixed in the emulsion during use are filtered and separated, and the oil is separated by a centrifuge. At the same time, the flocculation generated by the demulsification of the emulsion during use is separated and recycled. The setting of the filtration mechanism ensures that the emulsion remains stable during the flow process of the device.
[0023] (2) In this invention, a detection mechanism is set up to detect the pH value of the emulsion in batches. The pH value is used to determine whether the emulsion has deteriorated. The deteriorated emulsion is output from the device and new liquid is added at the same time. The emulsion that has not deteriorated continues to be recycled.
[0024] (3) In this invention, the replenishment mechanism is used to cooperate with the detection mechanism. When the emulsion fails the detection, the replenishment mechanism mixes the new liquid and reuses the flocculation separated in the filtration mechanism. This ensures that the concentration of the emulsion in the device will not decrease after long-term use, and further improves the service life of the emulsion. Attached Figure Description

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0042] Example 1
[0043] like Figure 1 As shown, a high-efficiency oil-water separation device for CNC lathes is characterized by comprising:
[0044] Filtering unit 1 is used to clean and filter the iron filings carried inside the emulsion and to separate and clean the impurities mixed in the emulsion.
[0045] The detection mechanism 2 is located behind the filter mechanism 1 and is used to detect the pH value of the emulsion to determine whether the emulsion has deteriorated. The detection mechanism 2 includes a detection component 21 that is connected to the filter mechanism 1 and is used to detect the emulsion, and a cleaning component 22 that is located inside the detection component 21 and is used to clean the inside of the detection component 21.
[0046] The replenishment mechanism 3 is located behind the detection mechanism 2 and is used to replenish and update the emulsion in conjunction with the detection mechanism 2.
[0047] In this embodiment, by setting up a detection mechanism 2 and a replenishment mechanism 3, the pH value of the emulsion is detected. Based on the pH value of the emulsion, it is determined whether the emulsion has deteriorated. The deteriorated emulsion is then output from the device, and new liquid is added to maintain the emulsion in the device in a relatively healthy state.
[0048] In detail, the used emulsion is passed into the filtration unit 1, which filters out the iron filings in the emulsion and separates the mixed oil and some of the flocs generated by demulsification. The filtered emulsion enters the testing unit 2 to test the pH value of the emulsion. Emulsion that fails the test is output to the device, and new liquid is added to the replenishment unit 3 at the same time. The flocs separated by the filtration unit 1 are reused.
[0049] It should be noted that emulsions can deteriorate after prolonged use due to the presence of anaerobic bacteria, causing changes in their pH value. The pH value of the emulsion can be used to determine whether it has deteriorated.
[0050] It is worth mentioning that, through the cooperation of the detection mechanism 2 and the replenishment mechanism 3, the emulsion can be replaced, ensuring that the emulsion in the device remains in a relatively healthy state and extending its service life.
[0051] Furthermore, such as Figure 2 , 3 As shown, the filtration mechanism 1 includes a filter element 11 for filtering iron filings and a separator 12 disposed behind the filter element 11 for separating oil stains. The filter element 11 includes a water tank 111 with an inlet and an outlet on the upper part of both sides and a cone-shaped lower part; a partition 112 disposed inside the water tank 111 to divide the water tank 111 into two parts; a filter plate 113 disposed on the side of the water tank 111 near the outlet; a sleeve 114 vertically slidably connected to the bottom of the water tank 111 and with a spring between the bottom and the water tank 111; a collection basket 115 movably disposed inside the sleeve 114; and a telescopic rod fixedly connected to the collection basket 115 and fixedly connected to the water tank 111.
[0052] In this embodiment, by setting up a filter plate 113 and a collection basket 115, the iron filings in the emulsion are filtered and recovered. The setting of the partition plate 112 stabilizes the emulsion water and causes all the iron filings to settle and accumulate at the bottom of the water tank 111, and are collected by the collection basket 115 for easy extraction and recovery.
[0053] In detail, the emulsion is introduced into the water tank 111 through the inlet. Under the obstruction of the baffle 112, it flows through the bottom of the water tank 111 and rises, then rises through the filter plate 113 and flows out from the outlet. The iron filings are blocked by the filter plate 113 and fall into the collection basket 115 at the bottom of the water tank 111 under the action of gravity. When the collection basket 115 has collected a certain amount of iron filings, the first telescopic cylinder 116 is activated, and the telescopic rod extends to move the collection basket 115 out of the water tank 111. During the upward movement of the collection basket 115, the sleeve 114 moves upward under the action of the spring to prevent the iron filings from gathering in the middle. After the collection basket 115 is cleaned, it descends again, pressing down the sleeve 114, and the iron filings slide back into the collection basket 115.
[0054] It should be noted that the collection basket 115 is made of a mesh material with holes that prevents iron filings from passing through, so that the collection basket 115 does not carry residual emulsion during its ascent, leaving only the collected iron filings.
[0055] It is worth mentioning that the water tank 111 ensures the stability of the water flow when the emulsion flows into the device, avoiding intermittent and unstable water flow as the emulsion flows further.
[0056] Furthermore, such as Figure 2 As shown, the separator 12 includes two sets of first centrifuges 121 connected to the water tank 111 and jointly connected to the rear conveying pipeline. The first centrifuges 121 are used to separate oil and emulsion. At the same time, the oil discharge outlets of the two sets of first centrifuges 121 are connected to the second centrifuges 122. The second centrifuges 122 are used to separate the emulsion flocculation in the oil. The second centrifuges 122 are also connected to a transfer pipe 123 for conveying the flocculation.
[0057] In this embodiment, by setting up a first centrifuge 121 and a second centrifuge 122, the emulsion and the mixed oil are first separated. Since the emulsion will break down during use, resulting in flocculation in the water, the density of the flocculation is relatively large. When passing through the first centrifuge 121, the flocculation will be mixed with the oil and separated together. At this time, the second centrifuge 122 needs to perform a more detailed separation to separate the flocculation from the oil.
[0058] In detail, the filtered emulsion is fed into the first centrifuge 121. After centrifugation, the oil mixed with flocculation is separated from the emulsion. The emulsion continues to be output, while the oil is input into the second centrifuge 122. The second centrifuge 122 performs centrifugation again, and the oil is output to the output device, while the flocculation is input into the transfer pipe 123 for later use.
[0059] It should be noted that the flocculation produced by emulsion demulsification can be mixed back into the emulsion through stirring or other methods for reuse.
[0060] It is worth mentioning that the use of centrifuges can achieve more precise separation of different types of components, reduce the mixing of oil into the emulsion and accelerate the deterioration of the emulsion. By setting up multiple first centrifuges 121, the emulsion can be continuously output to the next stage, thereby improving efficiency.
[0061] Furthermore, such as Figure 4 , 5 As shown, the detection component 21 includes multiple isolation tubes 211 connected to the first centrifuge 121 and respectively provided with a discharge pipe and a connecting pipe at both ends, a detection element 212 disposed above the isolation tubes 211, and a control element 213 disposed below the isolation tubes 211 and cooperating with the detection element 212. The detection element 212 includes a pH meter 2121 and a linear motor 2122 for fixing the pH meter 2121 and driving the pH meter 2121 to move between the isolation tubes 211.
[0062] It also includes a detection hole 2123 located on the upper part of the isolation tube 211, multiple cover plates 2124 located inside the detection hole 2123 and hinged to the side wall of the detection hole 2123, a second telescopic cylinder 2125 fixedly connected to the telescopic rod and pH meter 2121 and fixedly mounted on the slider of the linear motor 2122, a stirring shaft 2126 located inside the isolation tube 211, and a first motor 2127 that drives the stirring shaft 2126 to rotate and is fixedly mounted on the isolation tube 211.
[0063] In this embodiment, by setting up a pH value meter 2121 and an isolation tube 211, a portion of the emulsion is input into the isolation tube 211, the pH value of the emulsion in the isolation tube 211 is measured, the qualified emulsion continues to be output through the connecting tube, and the unqualified emulsion is output through the discharge tube.
[0064] In detail, the separated emulsion flows into one of the isolation tubes 211. The pH meter 2121 moves above the isolation tube 211 under the drive of the linear motor 2122. The first motor 2127 drives the stirring shaft 2126 to rotate, so that the emulsion in the isolation tube 211 is fully mixed. At the same time, the second telescopic cylinder 2125 drives the pH meter 2121 to move downward and into the detection hole. The detection head of the pH meter 2121 presses down the cover plate 2124 and extends into the isolation tube 211 for detection. After the detection is completed, the pH meter 2121 moves upward and switches to the isolation tube 211 that needs to be measured.
[0065] It should be noted that a torsion spring is provided below the cover plate 2124, which allows the cover plate 2124 to rotate under the pressure of the pH value measuring instrument 2121, thus opening it. When the test is completed, the cover plate 2124 rotates back to its initial state under the action of the spring, and the cover plate 2124 closes the test hole 2123 to prevent the emulsion in the isolation tube 211 from flowing out.
[0066] It is worth mentioning that the pH meter 2121 needs to work in conjunction with the isolation tube 211. When the pH meter 2121 is testing one isolation tube 211, the next isolation tube 211 is opened to fill with water. The previous isolation tube 211 is drained, and the pH meter moves to achieve cyclic testing.
[0067] Furthermore, such as Figure 6 As shown, the control component 213 includes a control rod 2131 slidably connected below the isolation pipe 211, an electric cylinder 2132 that drives the control rod 2131 to move back and forth, and a first contact switch 2133 fixed at both ends of the control rod 2131. The contact switch controls the opening and closing of the solenoid valve located inside the discharge pipe and the connecting pipe.
[0068] In this embodiment, the electric cylinder 2132 is used to control the forward and backward movement of the control rod, and the control rod 2131 is used to contact the contact switch to control the opening and closing of the solenoid valve inside the discharge pipe and the connecting pipe, thereby realizing the determination of the retention or removal of emulsion in the isolation pipe 211.
[0069] In detail, when the pole control lever 2131 moves towards the discharge pipe, the contact switch on the control lever 2131 closes, and all the solenoid valves on the discharge pipe open, allowing the emulsion to flow out of the discharge pipe. When the pole control lever 2131 moves towards the connecting pipe, the contact switch at the other end of the control lever 2131 closes, and all the solenoid valves on the connecting pipe open, allowing the emulsion to flow out of the connecting pipe and into the subsequent structure.
[0070] It should be noted that the electric cylinder 2132 and the pH meter 2121 need to be connected to the controller. The controller controls the movement of the electric cylinder 2132 so that the movement of the electric cylinder 2132 matches the data measured by the pH meter 2121.
[0071] Furthermore, such as Figure 7 , 8 As shown, the cleaning component 22 includes a cleaning element 221 disposed inside the isolation tube 211 and a contact element 222 disposed outside the isolation tube 211 to control the operation of the cleaning element 221. The cleaning element 221 includes a magnetically pleasing metal scraper 2211 disposed inside the isolation tube 211 with its edge in contact with the inner wall of the isolation tube 211 and its center not in contact with the stirring shaft 2126; a threaded rod 2212 fixedly connected to both ends of the isolation tube 211 and threadedly connected to the scraper 2211; a second motor 2213 that drives the threaded rod 2212 to rotate and is installed outside the isolation tube 211; and a magnetic baffle 2214 that is slidably connected to the stirring shaft 2126.
[0072] It also includes two cleaning rods 2215 that are mounted above the liquid outlet pipe and connected to the central axis of the isolation pipe 211. The two cleaning rods 2215 are attached to the side wall of the isolation pipe 211, and the scraper 2211 drives the cleaning rods 2215 to rotate through the transmission of the gear rack 2216.
[0073] A rack 2216 is fixedly connected to the scraper 2211, and a first gear 2217 is provided on the moving path of the rack 2216. The first gear 2217 is fixedly connected to the isolation tube 211. The first gear 2217 is fixedly connected to the first bevel gear 2218. A second bevel gear 2219 is fixedly connected to the rotating shaft 331 of the two cleaning rods 2215. The first bevel gear 2218 meshes with the two second bevel gears 2219 at the same time.
[0074] In this embodiment, the interior of the isolation tube 211 is cleaned by setting a metal scraper 2211 and a cleaning rod 2215. For unqualified emulsions, some residue will be left on the wall after the emulsion is discharged from the isolation tube 211. This part of the emulsion will affect the emulsion input into the isolation tube 211 next, causing the detection to deviate. Therefore, it is necessary to discharge as much of the unqualified emulsion in the isolation tube 211 as possible from the discharge tube.
[0075] In detail, when the test is completed and the emulsion needs to be discharged from the isolation tube 211, the first motor 2127 drives the stirring shaft 2126 to rotate, splashing the emulsion on the stirring shaft 2126 onto the side wall of the isolation tube 211. The second motor 2213 drives the scraper 2211 to move, and the scraper 2211 drives the baffle 2214 to move, pushing the emulsion into the discharge tube. When the emulsion has mostly flowed out, the baffle 2214 is stopped on the stirring shaft 2126. The scraper 2211 continues to move forward to scrape off all the emulsion on the side wall of the isolation tube 211. When the rack 2216 contacts the first gear 2217, the first gear 2217 drives the first bevel gear 2218 to rotate. The first bevel gear 2218 simultaneously drives the second bevel gear 2219 to rotate, causing the cleaning rod 2215 to rotate from top to bottom along the side wall of the isolation tube 211, scraping all the excess emulsion into the discharge tube, thus cleaning the isolation tube 211.
[0076] It should be noted that the magnetic metal scraper 2211 and baffle 2214 are designed to prevent the emulsion from flowing through the middle of the scraper 2211 to the already cleaned part in the early stage of emulsion discharge. The magnetic design allows the scraper 2211 and baffle 2214 to be both tightly connected and quickly separated.
[0077] It is worth mentioning that by cleaning up the residue of substandard emulsion, the test results become more accurate, and the pH value is neutralized.
[0078] Furthermore, such as Figure 8 As shown, the contact element 222 includes a push rod 2221 fixedly connected to one end of the control rod 2131, a moving block 2222 slidably connected to the isolation tube 211 and provided above it for controlling the contact switch of the second motor 2213, and a lever 2223 with its lower end hinged to the push rod 2221 and its upper end hinged to the moving block 2222.
[0079] In this embodiment, by setting the lever 2223 and the moving block 2222, the second motor 2213 is controlled, so that the second motor 2213 can start cleaning the isolation pipe 211 at the same time as the solenoid valve on the discharge pipe is opened.
[0080] In detail, the control lever 2131 moves towards the discharge pipe, causing the push rod 2221 to move. The push rod 2221 drives the lever 2223 to rotate, and the lever 2223 pushes the moving block 2222 upward, causing the contact switch on the moving block 2222 to close. The second motor 2213 starts and begins to work.
[0081] It is worth mentioning that by controlling the start of the second motor 2213 simultaneously through the control lever 2131, the cleaning component 221 can cooperate with the detection component 21, so that the cleaning component 221 can promote the discharge of emulsion in the early stage while completing the cleaning work.
[0082] Furthermore, such as Figure 9 As shown, the supplementary mechanism 3 includes a mixing tank 31 for mixing the new liquid and connected to the connecting pipes on each isolation pipe 211, a collection box 32 connected to the isolation pipe 211 and used to store the emulsion, a mixing component 33 disposed inside the mixing tank 31 and used to assist in mixing the new liquid, and a trigger component 34 for driving the mixing component 33.
[0083] In this embodiment, by setting up a mixing pipe and a receiving box, storage space is provided for the emulsion, so that the emulsion can be used at any time, and it is also convenient to replenish the emulsion with new liquid.
[0084] In detail, when the emulsion passes the test, it flows into the mixing tank 31 and then into the collection tank 32 without the need for additional liquid. When the emulsion fails the test, the original liquid and water are mixed in the mixing tank 31 to prepare the new liquid, which is then added to the collection tank 32.
[0085] Furthermore, such as Figure 10-12 As shown, the mixing component 33 includes a rotating shaft 331 disposed inside the mixing tank 31, a third motor 332 that drives the rotating shaft 331 to rotate and is fixedly mounted on the mixing tank 31, a discharge pipe 333 fixedly mounted on the rotating shaft 331 and rotatably connected and communicating with the transfer pipe 123, a conical filter plate 334 fixed below the discharge pipe 333, a stirring blade 335 fixed on the conical filter plate 334, a grinding block 336 disposed below the conical filter plate 334, a plug 337 disposed above the grinding block 336, and a third telescopic cylinder 338 that is fixedly connected to the grinding block 336 and installed inside the mixing pipe.
[0086] In this embodiment, by setting up the grinding block 336 and the star-chasing filter plate, the flocculation of the emulsion can be reused. The grinding block 336 and the conical filter plate 334 work together to grind the flocculation into powder for remixing, and then mix it with the original liquid and water for reuse.
[0087] In detail, when the unqualified emulsion is discharged from the device, new liquid needs to be introduced to replenish it. The original liquid and water are introduced into the mixing tank 31. At the same time, the flocculated liquid is transported to the mixing tank 31 through the transfer pipe 123 and enters the discharge pipe 333. It falls from the discharge pipe 333 into the space between the conical filter plate 334 and the grinding block 336. At the same time, the third motor 332 is started, driving the conical filter plate 334 to rotate. The conical filter plate 334 and the grinding block 336 rotate relative to each other to grind and disperse the flocculated liquid. Meanwhile, the rotating shaft 331 works with the stirring blade 335 to achieve the mixing and fusion of the emulsion. At the same time, the ground flocculated liquid is gradually carried out of the conical filter plate 334 and mixed in the emulsion to achieve the reuse of the emulsion flocculation. After the mixing is completed, the new liquid is added into the collection tank 32.
[0088] When the emulsion passes the inspection, the extension rod of the third cylinder shortens, causing the grinding block 336 to move downwards. Simultaneously, the plug 337 moves downwards, blocking the outlet of the transfer pipe 123 to prevent flocculation from being discharged.
[0089] It should be noted that the gap between the grinding block 336 and the conical filter plate 334 gradually decreases from top to bottom, which can fully grind the flocculation. Furthermore, the size of the flocculation can be controlled by the size of the holes on the conical filter plate 334, so that the fully ground flocculation can enter the emulsion through the holes.
[0090] It is worth mentioning that the flocculation is reused by setting the grinding block 336, so that the flocculation can be fully mixed in the new emulsion, thereby replenishing the emulsion and avoiding a significant decrease in the concentration of the emulsion under long-term use.
[0091] Furthermore, such as Figure 13 As shown, the trigger 34 includes a fixed rod 341 fixedly connected to the mixing tank 31, a trigger rod 342 with both ends located inside the two adjacent push rods 2221 and rotatably connected to the fixed rod 341 in the middle, and a second contact switch 343 set at the tail of the trigger rod 342 to control the third motor 332 and the third telescopic cylinder 338.
[0092] In this embodiment, by setting a trigger rod 342 and a fixed rod 341, the control of the third motor 332 is realized, and the movement of the third motor 332 is associated with the movement of the control rod 2131, so that the control rod 2131 can synchronously control the third motor 332 and the third telescopic cylinder 338. By utilizing the pH value detection structure, multiple steps can be started simultaneously.
[0093] In detail, the control lever 2131 moves towards the discharge pipe, which drives the push rod 2221 to move. The push rod 2221 pushes the trigger rod 342 to rotate. After the trigger rod 342 rotates, its tail contacts the contact switch, and the contact switch is connected. The third motor 332 and the third telescopic cylinder 338 start to work.
[0094] It should be noted that, since there are multiple isolation tubes 211, a set of trigger rods 342 is set between each pair of adjacent isolation tubes 211. Since only one isolation tube 211 is performing pH value detection at a time, the trigger rods 342 will rotate, and only one set of multiple isolation tubes 211 will be triggered at the same time.
[0095] It is worth mentioning that by controlling the operation of the trigger 34 through the control lever 2131, the requirements for intelligent control of the device are reduced. The controller only needs to receive the information from the pH meter 2121 and control the electric cylinder 2132.
[0096] Example 2
[0097] Furthermore, such as Figure 14 , 15 As shown, the separation process of the CNC lathe oil-water high-efficiency separation device includes the following steps:
[0098] Step 1, filtration step: The emulsion is input into the water tank 111 through the inlet. Blocked by the baffle 112, it flows through the bottom of the water tank 111 and rises, passing through the filter plate 113 and flowing out from the outlet. The iron filings are blocked by the filter plate 113 and fall into the collection basket 115 at the bottom of the water tank 111 under the action of gravity. When the collection basket 115 has collected a certain amount of iron filings, the first telescopic cylinder 116 is activated, and the telescopic rod extends to move the collection basket 115 out of the water tank 111. During the upward movement of the collection basket 115, the sleeve 114 moves upward under the action of the spring, preventing the iron filings from gathering in the middle. After the collection basket 115 is cleaned, it descends again, pressing down the sleeve 114, and the iron filings slide back into the collection basket 115. The filtered emulsion is fed into the first centrifuge 121. After centrifugation, the oil mixed with flocculation is separated from the emulsion. The emulsion continues to be output, while the oil is input into the second centrifuge 122. The second centrifuge 122 performs centrifugation again, and the oil is output to the output device, while the flocculation is input into the transfer pipe 123 for later use.
[0099] Step two, the testing step: The separated emulsion flows into one of the isolation tubes 211. The pH meter 2121, driven by the linear motor 2122, moves above the isolation tube 211. The first motor 2127 drives the stirring shaft 2126 to rotate, so that the emulsion in the isolation tube 211 is fully mixed. At the same time, the second telescopic cylinder 2125 drives the pH meter 2121 to move downward and into the testing hole. The testing head of the pH meter 2121 presses down the cover plate 2124 and extends into the isolation tube 211 for testing. After the test is completed, the pH meter 2121 moves upward and switches to the isolation tube 211 that needs to be measured.
[0100] When the test is completed and the emulsion needs to be discharged from the isolation tube 211, the first motor 2127 drives the stirring shaft 2126 to rotate, splashing the emulsion on the stirring shaft 2126 onto the side wall of the isolation tube 211. The second motor 2213 drives the scraper 2211 to move, and the scraper 2211 drives the baffle 2214 to move, pushing the emulsion into the discharge tube. When the emulsion has mostly flowed out, the baffle 2214 is stopped on the stirring shaft 2126. The scraper 2211 continues to move forward to scrape off all the emulsion on the side wall of the isolation tube 211. When the rack 2216 contacts the first gear 2217, the first gear 2217 drives the first bevel gear 2218 to rotate. The first bevel gear 2218 simultaneously drives the second bevel gear 2219 to rotate, causing the cleaning rod 2215 to rotate from top to bottom along the side wall of the isolation tube 211, scraping all the excess emulsion into the discharge tube, thus cleaning the isolation tube 211.
[0101] The qualified emulsion is fed into the mixing tank 31, and then into the collection tank 32.
[0102] Step 3, supplementary steps: control lever 2131 moves towards the discharge pipe, driving push rod 2221 to move. Push rod 2221 pushes trigger rod 342 to rotate. After trigger rod 342 rotates, its tail contacts the contact switch, the contact switch is connected, and the third motor 332 and the third telescopic cylinder 338 start to work. The raw liquid and water are input into the mixing tank 31. At the same time, the flocculated material is transported to the mixing tank 31 through the transfer pipe 123 and enters the discharge pipe 333. It falls from the discharge pipe 333 into the space between the conical filter plate 334 and the grinding block 336. At the same time, the third motor 332 starts, driving the conical filter plate 334 to rotate. The conical filter plate 334 and the grinding block 336 rotate relative to each other, grinding and dispersing the flocculated material. Meanwhile, the rotating shaft 331 works with the stirring blade 335 to achieve the stirring and fusion of the emulsion. Gradually, the ground flocculated material is carried out of the conical filter plate 334 and mixed in the emulsion, realizing the reuse of the emulsion flocculation. After mixing is completed, the new liquid is added into the collection tank 32.
