Description

Technical Field

[0001] This invention relates to the field of machine tool technology, specifically to a purification device and a consumable-free treatment method for machine tool waste oil. Background Technology

[0002] Machine tools are machines used to manufacture machinery and equipment. They play a vital role in the modernization of the national economy. Lathes are machine tools that use cutting tools to turn rotating workpieces. Drills, reamers, taps, dies, and knurling tools can also be used on lathes for corresponding machining. Lathes are mainly used to machine shafts, discs, sleeves, and other workpieces with rotating surfaces. They are the most widely used type of machine tool in machinery manufacturing and repair shops.

[0003] When a machine tool is cutting, it needs to use cutting oil to cool the workpiece and ensure the safe and stable operation of the cutting process. During the cutting process, a large amount of iron filings and impurities are generated, which will result in a large amount of iron filings and impurities in the cutting oil, forming dirty oil. After the cutting is completed, the cutting oil used for cooling needs to be purified to ensure the reuse of the cutting oil, which is energy-saving and environmentally friendly.

[0004] Publication (Announcement) No.: CN110877936B discloses a cutting fluid purification and filtration device. This purification device is equipped with a pre-filter before the fluid enters the system to perform primary impurity filtration. Furthermore, the pre-filter is removable and washable. After the cutting fluid enters the separator, the oil layer floats to the surface due to gravity. The oil and water are separated by an oil-water separator, and the floating oil is discharged from the overflow port. The cutting fluid after oil-water separation enters a three-stage filtration device. After being filtered layer by layer, it is cleaner for reuse and has a high filtration efficiency.

[0005] The aforementioned purification device for cutting oil uses a large number of filter media to intercept and filter iron filings and other impurities in the cutting oil. Although it can complete the purification of cutting oil, the intercepted iron filings cannot self-clean, requiring frequent replacement of filter media or repeated disassembly and cleaning, which is time-consuming and laborious, and increases the purification cost. Furthermore, the purification device cannot perform consumable-free purification and removal of iron filings or perform various self-cleaning purification processes, resulting in high operating costs and high difficulty in subsequent maintenance. Summary of the Invention

[0006] The purpose of this invention is to provide a purification device and a consumable-free treatment method for machine tool waste oil, so as to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to a purification device for machine tool sludge oil, comprising a purification box with an open top, a top cover detachably mounted on the top of the purification box via bolts, a discharge pipe connected to the bottom of one side of the purification box, a circular cylinder detachably fixed at the center of the lower surface of the top cover, a feed pipe extending through the center of the top cover and correspondingly into the circular cylinder, multiple overflow zones arranged in a circular array around the top of the circular cylinder, a conical hopper detachably mounted at the bottom of the circular cylinder, and a slag discharge pipe connected to the bottom of the conical hopper, a power mechanism mounted at the center of the lower surface of the top cover inside the circular cylinder, and multiple purification mechanisms arranged in a circular array on the power mechanism, each extending into the circular cylinder to perform iron filings adsorption. The power mechanism drives the multiple purification mechanisms to perform synchronized circumferential rotation and self-rotation. These multiple purification mechanisms are used to adsorb and purify iron filings in the sludge oil inside the circular cylinder, and a cleaning mechanism is assembled on the purification mechanisms to actively clean the iron filings adsorbed on the purification mechanisms.

[0009] Furthermore, an installation area is provided at the bottom center of the purification box, which is configured to cooperate with the slag discharge pipe, and mounting seats are symmetrically installed on both sides of the purification box.

[0011] Furthermore, each of the multiple purification mechanisms includes a drive shaft that rotates through the ring gear ring, a through hole is provided at the center of each drive shaft, a magnetic rod can be detachably installed at the bottom of each drive shaft, and a No. 3 gear is fixedly sleeved on the top of each drive shaft, with each No. 3 gear meshing with the internal gear ring.

[0012] Furthermore, the cleaning mechanism includes a pressure ring fixedly sleeved on the bottom of the outer side of multiple drive shafts, and a first ring piece slidably sleeved at intervals on the outer side of multiple magnetic rods. Multiple scrapers are evenly and detachably installed on the inner wall of the first ring piece, and the multiple scrapers contact the outer wall of the magnetic rods to complete the scraping. A second ring piece is slidably sleeved above the first ring piece on the outer side of the multiple magnetic rods. The second ring piece is provided with a clearance area that cooperates with the first ring piece. Multiple cleaning grooves are opened in the clearance area of ​​the second ring piece. The multiple cleaning grooves are configured to cooperate with the multiple scrapers. A sealing element is slidably inserted through the top of each of the multiple cleaning grooves on the second ring piece. An extension plate is installed on one side of the sealing element. The top edge of the second ring piece is in contact with the pressure ring, and the pressure ring is not in contact with the multiple sealing elements. A return spring is installed between the extension plate and the second ring piece. The return spring drives the sealing element to slide and extend into the cleaning groove to seal it.

[0013] Furthermore, the No. 1 ring component is a circular structure formed by detachably splicing the No. 1 half component and the No. 2 half component with bolts.

[0014] Furthermore, a No. 1 plate is installed on one side of both the No. 1 half-piece and the No. 2 half-piece. A No. 2 plate that mates with the No. 1 plate is symmetrically arranged on both sides of the No. 2 ring piece. A guide rod is slidably inserted through the No. 2 plate. The bottom of the guide rod is fixedly connected to the No. 1 plate. A plug is installed on the top of the guide rod. A tension spring is sleeved on the outside of the guide rod. The tension spring is located between the plug and the No. 2 plate.

[0015] Furthermore, a cleaning ring is slidably installed on the inner wall of the cylindrical tube. The inner wall of the cleaning ring is detachably and fixedly connected to multiple No. 1 rings via connecting rods. Two sliding plates are slidably arranged in a circular trajectory on the top of the cleaning ring. An electric push rod is fixedly inserted through the top cover. The bottom of the electric push rod is connected to one of the sliding plates, and a limiting rod is installed on the upper surface of the other sliding plate. The top of the limiting rod is slidably inserted through the top cover.

[0016] Furthermore, the electric actuator and the limiting rod are respectively slidably disposed through the annular component.

[0017] The present invention also provides a consumable-free treatment method for a purification device for machine tool waste oil, the method specifically including the following steps:

[0018] Step 1: First, the sludge is introduced into the cylinder through the feed pipe. Then, multiple purification mechanisms are powered on to enable them to adsorb. Subsequently, the iron filings in the sludge in the cylinder come into contact with the purification mechanisms to complete the adsorption process, thereby completing the multi-point synchronous adsorption and purification process of the sludge in the cylinder.

[0019] Step 2: The power mechanism drives multiple purification units to rotate in a circular cylinder. The rotation of the multiple purification units drives the flow of sludge and oil in the circular cylinder, and at the same time, the iron filings at various positions can be quickly adsorbed and purified by the purification units, increasing the adsorption range of the purification units.

[0020] Step 3: Subsequently, the purified supernatant sludge flows out from the overflow area at the top of the cylinder into the purification chamber, and finally the sludge sludge from removing iron filings is discharged through the discharge pipe;

[0021] Step 4: When cleaning the purification mechanism, turn off the power to the purification mechanism and use the power mechanism to drive multiple purification mechanisms to centrifugally rotate and throw out the adsorbed iron filings.

[0022] Step 5: Simultaneously, the cleaning mechanism performs multiple scraping and cleaning operations on the purification unit, and finally, the iron filings are discharged through the slag discharge pipe before the next purification operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention features multiple purification mechanisms that, with the assistance of a power mechanism, rotate circumferentially within a cylindrical cavity. This allows for full contact with iron filings, increasing the adsorption range of the magnetic rods within the cylinder. Simultaneously, the magnetic rods are guided by an internal gear ring during their circumferential rotation. Since the No. 3 gear on each magnetic rod meshes with the internal gear ring, the magnetic rods are driven to rotate synchronously while simultaneously rotating on their own axis. This ensures that the magnetic rods evenly contact the iron filings on all sides for adsorption, guaranteeing adsorption accuracy.

[0025] 2. The present invention has a power mechanism that disconnects the power to the magnetic rods and then starts the second motor. The power is transmitted to the internal gear ring via the second gear to drive it to rotate. Since the internal gear ring meshes with the third gear, multiple magnetic rods are driven to rotate at a set speed with the third gear. During the set speed rotation of the magnetic rods, the iron filings adsorbed on them are thrown off by centrifugal force to complete one cleaning cycle.

[0026] 3. This invention features a cleaning mechanism. When the power mechanism drives multiple magnetic rods to rotate at a synchronized speed, the electric push rod is activated. Multiple scrapers inside the first ring and the second ring complete two scraping and cleaning operations on the outer wall of the magnetic rods, improving the cleaning accuracy. After cleaning, the electric push rod resets and drives the first ring to fit onto the second ring. Simultaneously, the scrapers on the first ring press the sealing element into the corresponding cleaning groove on the second ring to complete a self-cleaning operation.

[0027] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0045] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0046] Example 1: The present invention provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a purification device for machine tool sludge includes a purification box 1 with an open top design. A top cover 2 is detachably installed on the top of the purification box 1 by bolts. A discharge pipe 3 is connected to the bottom of one side of the purification box 1. A material pump for material extraction is installed at the end of the discharge pipe 3. A cylindrical cylinder 4 is detachably fixed at the center of the lower surface of the top cover 2. A feed pipe 5 is opened through the center of the top cover 2 and extends into the cylindrical cylinder 4. Multiple overflow zones 6 are arranged in a circular array around the top of the cylindrical cylinder 4. Metal filter screens 39 are detachably installed in each of the multiple overflow zones 6. A conical hopper 7 is detachably installed at the bottom of the cylindrical cylinder 4, and a slag discharge pipe 8 is connected to the bottom of the conical hopper 7. A material extraction pump is installed at the end of the slag discharge pipe 8. The material pump has a slag discharge pipe 8 that is fixedly installed through the bottom of the purification box 1. A power mechanism is installed inside the circular cylinder 4 at the center of the lower surface of the top cover 2. Multiple purification mechanisms are arranged in a circular array on the power mechanism. The multiple purification mechanisms extend into the circular cylinder 4 to complete the iron filings adsorption action. The power mechanism drives the multiple purification mechanisms to complete synchronous circumferential rotation and self-rotation. The multiple purification mechanisms are used to adsorb and purify the iron filings in the sludge oil in the circular cylinder 4. A cleaning mechanism is installed on the purification mechanism to actively clean the iron filings adsorbed on the purification mechanism. An installation area 9 is provided in the middle of the bottom of the purification box 1. The installation area 9 is arranged in conjunction with the slag discharge pipe 8. Installation seats 10 are symmetrically installed on both sides of the purification box 1.

[0047] The electrical control components of the power mechanism, purification mechanism, and cleaning mechanism are all connected to switches via wires, and the switches are electrically connected to controllers. The specific structure of the controllers is not limited.

[0048] Example 2: Based on the power mechanism provided in Example 1, this example provides a further technical solution for the power mechanism.

[0049] like Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the power mechanism includes an annular component 11 fixedly installed on the top of the inner wall of the cylindrical tube 4. An annular gear ring 12 is concentrically rotatably installed inside the annular component 11. A blocking plate 13 is installed at the bottom of the annular gear ring 12 and is rotatably sleeved on the outside of the feed pipe 5. A first motor 14 is installed on one side of the upper surface of the top cover 2. A first gear 15 is installed at the output end of the first motor 14 and meshes with the annular gear ring 12 for transmission. An inner gear ring 16 is rotatably installed on the lower surface of the top cover 2 and is concentrically arranged with the annular gear ring 12. The inner gear ring 16 is located above the annular gear ring 12. A second motor 17 is installed on one side of the upper surface of the top cover 2. A second gear 18 is installed at the output end of the second motor 17 and meshes with the inner gear ring 16 for transmission. Electromagnetic brakes are installed on the shaft ends of the first motor 14 and the second motor 17 to lock the rotation of the shaft ends of the first motor 14 and the second motor 17.

[0050] During a single cleaning cycle: the magnetic rod 20 is de-energized by a power mechanism, thus eliminating its adsorption force. Then, the second motor 17 is started, and the power is transmitted to the internal gear ring 16 via the second gear 18, causing it to rotate. Since the internal gear ring 16 meshes with the third gear 21, multiple magnetic rods 20 are driven to rotate at a synchronized speed with the third gear 21. During the synchronized rotation of the magnetic rods 20, the centrifugal force is used to throw off the iron filings adsorbed on them, completing one cleaning cycle.

[0051] In this embodiment of the invention, each of the multiple purification mechanisms includes a drive shaft 19 rotatably mounted on an annular gear ring 12. A through hole 40 is provided at the center of each of the multiple drive shafts 19 for threading the wires of the magnetic rod 20. At the same time, the multiple magnetic rods 20 are powered by a conductive slip ring. Magnetic rods 20 can be detachably mounted at the bottom of each of the multiple drive shafts 19. A third gear 21 is fixedly mounted on the top of each of the multiple drive shafts 19. The multiple third gears 21 are meshed with the inner gear ring 16 and are located below the second gear 18.

[0052] During purification: Multiple purification mechanisms are installed. Magnetic rods 20 are energized to generate adsorption force to attract iron filings. Simultaneously, with the assistance of a power mechanism, motor 14 is started, and gear 15 meshes with ring gear 12 for transmission, driving the ring gear 12 and multiple purification mechanisms to rotate circumferentially. This allows multiple purification mechanisms to rotate circumferentially within the cylindrical cylinder 4, ensuring full contact with the iron filings and increasing the adsorption range of the multiple magnetic rods 20 within the cylindrical cylinder 4. While the multiple magnetic rods 20 rotate circumferentially, they are guided by an inner gear ring 16, which is locked and prevented from rotating by motor 17. Since gear 21 on the multiple magnetic rods 20 meshes with the inner gear ring 16, the multiple magnetic rods 20 simultaneously rotate circumferentially and rotate on their own axis, ensuring that the multiple magnetic rods 20 evenly contact the iron filings on all sides for adsorption, thus guaranteeing adsorption accuracy.

[0053] Example 3: Based on the cleaning mechanism provided in Example 1, this example provides a further technical solution for the cleaning mechanism.

[0054] like Figures 9-15 As shown, the cleaning mechanism includes a pressure ring 22 fixedly sleeved on the bottom of the outside of multiple drive shafts 19, and a first ring 23 slidably sleeved on the outside of multiple magnetic rods 20 at intervals. Multiple scrapers 24 are evenly and detachably installed on the inner wall of the first ring 23. The multiple scrapers 24 contact the outer wall of the magnetic rods 20 to complete the scraping. A second ring 25 is slidably sleeved above the first ring 23 outside the multiple magnetic rods 20. The second ring 25 contacts the outer wall of the magnetic rods 20. The second ring 25 is provided with a clearance area for the first ring 23 to cooperate with. The second ring 25 is inserted into the first ring 23 through the clearance area.

[0055] Multiple cleaning grooves 26 are provided in the clearance area of ​​the second ring 25. The multiple cleaning grooves 26 are configured to cooperate with multiple scrapers 24. The multiple scrapers 24 enter the multiple cleaning grooves 26 to complete the cleaning action. A sealing element 27 is slidably inserted into the top of each of the multiple cleaning grooves 26 on the second ring 25. An extension plate 28 is installed on one side of the sealing element 27. The top edge of the second ring 25 is in contact with the pressure ring 22. The pressure ring 22 does not contact the multiple sealing elements 27. The multiple sealing elements 27 are hidden and stored by the pressure ring 22. A return spring 29 is installed between the extension plate 28 and the second ring 25. The return spring 29 drives the sealing element 27 to slide and extend into the cleaning groove 26 to seal it.

[0056] During the secondary cleaning: with the cleaning mechanism, under normal conditions, the electric push rod 37 resets multiple first ring parts 23 and second ring parts 25 to the top of the magnetic rod 20 and drives the top edge of the second ring part 25 to contact the pressure ring 22, so that the first ring part 23 is correspondingly fitted on the second ring part 25 and the scraper 24 is hidden in the cleaning groove 26. At this time, the tension spring 34 is deformed.

[0057] When the power mechanism drives multiple magnetic rods 20 to rotate at a synchronized speed, the electric push rod 37 is activated, pushing the cleaning ring 35 to slide up and down inside the cylindrical cylinder 4 to complete the scraping and cleaning of the inner wall of the cylindrical cylinder 4. At the same time, multiple first rings 23 and second rings 25 move down in conjunction with the mechanism. Since the multiple magnetic rods 20 rotate at a synchronized speed, relative rotation occurs between the magnetic rods 20 and the first and second rings 23 and 25. The multiple scrapers 24 inside the first ring 23 and the second ring 25 complete two scraping and cleaning operations on the outer wall of the magnetic rods 20, improving the cleaning accuracy of the magnetic rods 20. When the first and second rings 25 separate from the pressure ring 22, the first and second rings 23 are driven to separate under the action of the tension spring 34 to complete the two scraping and cleaning operations. At the same time, the sealing element 27 is driven to extend into the cleaning groove 26 under the push of the return spring 29 to complete the sealing and prevent iron filings from entering.

[0058] The cleaning mechanism is driven up and down synchronously by the electric push rod 37 to clean the magnetic rod 20. After cleaning, the electric push rod 37 resets and drives the first ring 23 to be fitted onto the second ring 25. At the same time, the scraper 24 on the first ring 23 squeezes the sealing member 27 and inserts it into the cleaning groove 26 on the second ring 25 to complete a self-cleaning operation, avoiding damage to the magnetic rod 20 caused by residual iron filings on the scraper 24. Meanwhile, the sliding of the cleaning ring 35 is guided by the limiting rod 38. Since the bottom of the electric push rod 37 and the limiting rod 38 are rotatably connected to the cleaning ring 35 through the sliding plate 36, the cleaning mechanism can avoid interference when multiple magnetic rods 20 rotate in a circle, so that the cleaning mechanism can follow the rotation of multiple magnetic rods 20. At the same time, during the rotation, the cleaning ring 35 forms a rotating scraping cleaning with the inner wall of the cylindrical cylinder 4.

[0059] In this embodiment of the invention, the first ring 23 is formed by detachably splicing a first half-piece 2301 and a second half-piece 2302 with bolts to form a ring structure. A first plate 30 is installed on one side of both the first half-piece 2301 and the second half-piece 2302. A second plate 31 that mates with the first plate 30 is symmetrically arranged on both sides of the second ring 25. A guide rod 32 is slidably inserted through the second plate 31. The bottom of the guide rod 32 is fixedly connected to the first plate 30. A plug 33 is installed on the top of the guide rod 32. A tension spring 34 is sleeved on the outside of the guide rod 32. The tension spring 34 is located between the plug 33 and the second plate 31. The tension spring 34 is stretched to release tension. Spring 34 drives the first ring 23 to separate from the second ring 25. A cleaning ring 35 is slidably installed on the inner wall of the cylindrical cylinder 4. The inner wall of the cleaning ring 35 is detachably and fixedly connected to multiple first rings 23 via connecting rod 41. Two sliding plates 36 are slidably arranged in a circular trajectory on the top of the cleaning ring 35. An electric push rod 37 is fixedly inserted on the top cover 2. The bottom of the electric push rod 37 is connected to one of the sliding plates 36, and a limiting rod 38 is installed on the upper surface of the other sliding plate 36. The top of the limiting rod 38 is correspondingly slidably inserted through the top cover 2. The electric push rod 37 and the limiting rod 38 are correspondingly slidably inserted through the ring 11.

[0060] Example 4: A consumable-free treatment method for a purification device for machine tool waste oil, the method specifically includes the following steps:

[0061] Step 1: First, the sludge oil is introduced into the cylindrical cylinder 4 through the feed pipe 5. Then, multiple purification mechanisms are powered on to make them adsorbent. Subsequently, the iron filings in the sludge oil in the cylindrical cylinder 4 come into contact with the purification mechanisms to complete the adsorption process, thereby completing the multi-point synchronous adsorption and purification process of the sludge oil in the cylindrical cylinder 4.

[0062] Step 2: The power mechanism drives multiple purification mechanisms to rotate in a circular motion inside the cylindrical cylinder 4. The rotation of the multiple purification mechanisms drives the flow of sludge and oil inside the cylindrical cylinder 4, while allowing iron filings at various locations to be quickly adsorbed and purified by the purification mechanisms, thus increasing the adsorption range of the purification mechanisms.

[0063] Step 3: Subsequently, the purified supernatant sludge flows out from the overflow area 6 at the top of the cylindrical cylinder 4 into the purification tank 1, and finally the sludge sludge from which the iron filings have been removed is discharged through the discharge pipe 3.

[0064] Step 4: When cleaning the purification mechanism, turn off the power to the purification mechanism and use the power mechanism to drive multiple purification mechanisms to centrifugally rotate and throw out the adsorbed iron filings.

[0065] Step 5: Simultaneously, the cleaning mechanism performs multiple scraping and cleaning operations on the purification unit, and finally, the iron filings are discharged through the slag discharge pipe 8 before proceeding to the next purification operation.

[0066] This invention provides a purification device and a consumable-free treatment method for machine tool waste oil. The specific working principle is as follows: First, the waste oil is introduced into the cylindrical cylinder 4 through the feed pipe 5. Then, multiple purification mechanisms are energized to enable them to adsorb. Subsequently, the iron filings in the waste oil in the cylindrical cylinder 4 come into contact with the purification mechanisms to complete the adsorption treatment, thereby completing the multi-point synchronous adsorption purification treatment of the waste oil in the cylindrical cylinder 4. With the assistance of the power mechanism, multiple purification mechanisms are driven to rotate in the cylindrical cylinder 4. The rotation of multiple purification mechanisms drives the waste oil in the cylindrical cylinder 4 to flow, and at the same time, the iron filings at each position can quickly complete the adsorption purification with the purification mechanisms, increasing the adsorption range of the purification mechanisms. Then, the purified supernatant waste oil flows out from the overflow area 6 at the top of the cylindrical cylinder 4 into the purification tank 1, and finally the waste oil with iron filings removed is discharged through the discharge pipe 3.

[0067] Meanwhile, the metal filter 39 can actively intercept unadsorbed iron filings, reducing the iron filings content in the overflowing sludge. With the assistance of the power mechanism, when cleaning the purification mechanism, the power to the purification mechanism is turned off, and the power mechanism drives multiple purification mechanisms to centrifugally rotate and throw out the adsorbed iron filings. At the same time, the cleaning mechanism completes multiple scraping and cleaning of the purification mechanism. Finally, the iron filings are discharged through the slag discharge pipe 8 for the next purification operation.

4. A consumable-free treatment method for a purification device for machine tool sludge oil, characterized in that: Using any one of the purification devices for machine tool waste oil according to claims 1-3, the treatment method specifically includes the following steps: Step 1: First, the sludge oil is introduced into the cylindrical cylinder (4) through the feed pipe (5). Then, multiple purification mechanisms are powered on to make them adsorbent. Subsequently, the iron filings in the sludge oil in the cylindrical cylinder (4) come into contact with the purification mechanism to complete the adsorption treatment, thereby completing the multi-point synchronous adsorption purification treatment of the sludge oil in the cylindrical cylinder (4). Step 2: Drive multiple purification mechanisms to rotate in the circular cylinder (4) through the power mechanism. The rotation of multiple purification mechanisms drives the oily waste in the circular cylinder (4) to flow, and at the same time, the iron filings at each position can quickly be adsorbed and purified by the purification mechanism, thereby increasing the adsorption range of the purification mechanism. Step 3: Subsequently, the purified supernatant sludge flows out from the overflow area (6) at the top of the cylindrical cylinder (4) into the purification tank (1), and finally the sludge sludge from removing iron filings is discharged through the discharge pipe (3); Step 4: When cleaning the purification mechanism, turn off the power to the purification mechanism and use the power mechanism to drive multiple purification mechanisms to centrifugally rotate and throw out the adsorbed iron filings. Step 5: At the same time, the cleaning mechanism completes multiple scraping and cleaning of the purification mechanism, and finally the iron filings are discharged through the slag discharge pipe (8) before the next purification work.
