Description

Technical Field

[0001] The invention belongs to the field of quenching oil treatment, and in particular relates to a quenching oil separator. Background Art

[0002] At present, in the metal processing process, in order to improve the mechanical properties of metal workpieces, heat treatment is usually required, among which quenching is the most important process. The capacity of the metal workpiece is enhanced by rapidly cooling the heated metal workpiece. When cooling, a quenching medium is usually required to accelerate the cooling. The quenching medium is generally water and quenching oil. Compared with water with low specific heat capacity, quenching oil with high specific heat capacity cools faster and more stably, so it is more popular.

[0003] After long-term use, quenching oil can be susceptible to moisture intrusion due to factors such as condensation from ambient humidity or rain infiltration. Water in quenching oil exists in three states: deposited water, suspended water, and emulsified water. Suspended and emulsified water have the greatest impact on the cooling capacity of the quenching oil, directly affecting the quenching oil's cooling performance, workpiece quality, and equipment life.

[0004] It is very difficult to remove suspended water and emulsified water. Generally, heating is used to heat the quenching oil to above 110°C. The water in the quenching oil will boil and then evaporate into gas. The gaseous water floats out from the top of the quenching oil. However, since the emulsified water will partially blend with the quenching oil, it may carry trace oil molecules when the water evaporates (especially when the oil droplet size in the emulsion is <1μm), which will cause part of the quenching oil to evaporate with the water, resulting in waste of quenching oil. Although the amount of quenching oil carried by water vapor is small, when the quenching oil contains more water or the quenching oil to be processed is more, the amount of wasted quenching oil is also considerable. Summary of the Invention

[0005] The object of the present invention is to provide a quenching oil separator, aiming to solve the technical problem of partial quenching oil waste caused by treating water in quenching oil by heating in the prior art.

[0006] The present invention is implemented as follows: a quenching oil separator includes a processing box, a side of the processing box is provided with a feeding port, another side of the processing box is provided with an oil outlet pipe, the top of the processing box is connected to a collection cover, and the top of the collection cover is connected to a steam pipe;

[0007] A water-permeable membrane is installed inside the treatment box, and the collection cover and the oil outlet pipe are located on both sides of the water-permeable membrane. The water-permeable membrane adopts a nanofiltration membrane (pore size 1nm). Water vapor can pass through the water-permeable membrane, but the water-permeable membrane will prevent the passage of quenching oil;

[0008] The processing box is also provided with a heating pipe inside. The heating pipe is located below the water-permeable membrane. When raw materials (quenching oil containing water) are introduced into the processing box, the raw materials are submerged above the top of the heating pipe. The heating pipe heats the raw materials to a temperature above 1.5 degrees Celsius. The water in the raw materials will vaporize, and the quenching oil will float out. One end of the steam pipe is then connected to an exhaust fan, which can extract the water vapor, thereby separating the quenching oil and water.

[0009] An oil removal film mechanism is also installed inside the processing box. The output end of the oil removal film mechanism is in contact with the bottom of the water-permeable membrane. The oil removal film mechanism is used to remove the oil film at the bottom of the water-permeable membrane to prevent the water-permeable membrane from being blocked by the oil film, which in turn leads to a reduction in the water flow rate of the water-permeable membrane, thereby improving the working efficiency of the device.

[0010] Further technical solution: the oil-removing film mechanism includes two sliders slidably mounted inside the processing box, a concentric tube is rotatably mounted between the two sliders, and abutment rollers are fixedly mounted at both ends of the concentric tubes. The oil-removing film mechanism also includes a plurality of oil-absorbing strips, both ends of all the oil-absorbing strips are respectively fixedly connected to the back ends of the two abutment rollers, and the plurality of oil-absorbing strips are evenly distributed around the abutment rollers. The plurality of oil-absorbing strips form an oil-absorbing cylinder, and the oil-absorbing strips are made of an elastic and relatively elastic oil-absorbing cotton material. The surface of the oil-absorbing cylinder contacts the bottom of the water-permeable membrane.

[0011] The oil film removal mechanism also includes a driving mechanism, which is installed inside the processing box. The output end of the driving mechanism is connected to one end of the concentric tube, and the driving mechanism is used to drive the left-turning tube to move horizontally.

[0012] Further technical solution: The driving mechanism includes a driving block and a second motor, the driving block is rotatably mounted at one end of the concentric tube, the second motor is fixedly mounted inside the processing box, the output shaft of the second motor is fixedly connected to a screw, one end of the screw is threadedly connected to the driving block.

[0013] Further technical solution: Gears are installed at both ends of the concentric tubes, and two racks adapted to the two gears are fixedly connected inside the processing box, and the racks and gears are meshed and connected.

[0014] Further technical solution: the oil film removal mechanism also includes a screwing and squeezing mechanism;

[0015] Specifically, the concentric tubes include a disconnected right-turn tube and a left-turn tube, the right-turn tube and the left-turn tube are rotatably mounted on two sliders respectively, an adjusting inner rod is inserted into the interior of the left-turn tube, one end of the adjusting inner rod is fixedly connected to a connecting rod, the interior of the right-turn tube is fixedly connected to an inner fixing block, one end of the connecting rod passes through the inner fixing block and is fixedly connected to a clamping head, a side of the inner fixing block close to the clamping head is provided with a clamping groove adapted to the clamping head, the interior of the right-turn tube is fixedly connected to a limiting ring, and a return spring is connected between the inner fixing block and the limiting ring;

[0016] In order to prevent the meshing of the gear and the rack from affecting the rotation of the left-turn tube, the two gears are a movable gear and a fixed gear. The fixed gear is fixedly mounted on the right-turn tube, and the movable gear is slidably mounted on the left-turn tube. The movable gear is fixedly connected to the adjusting inner rod through a connecting column. A sliding hole for the connecting column to move is opened on the side of the left-turn tube.

[0017] The driving block is rotatably mounted on one end of the left-turn tube;

[0018] The output end of the screwing and squeezing mechanism is connected to one end of the left-turning tube, and the screwing and squeezing mechanism is used to drive the left-turning tube to rotate.

[0019] Further technical solution: The screwing and squeezing mechanism includes a driven bevel gear and a telescopic rod, wherein the driven bevel gear is fixedly mounted on the left-turning tube, the telescopic rod is fixedly mounted inside the processing box, a first motor is fixedly mounted on the movable end of the telescopic rod, an output shaft of the first motor is fixedly connected to a driving bevel gear, and the driving bevel gear is capable of meshing with the driven bevel gear;

[0020] After the oil suction cylinder is saturated, the left-turn pipe is transported to the bottom of the driving bevel gear through the driving mechanism, and then the telescopic rod drives the first motor and the driving bevel gear to descend, so that the driving bevel gear and the driven bevel gear are engaged, and the first motor can drive the left-turn pipe to rotate through the driving bevel gear and the driven bevel gear;

[0021] In order to make the clamping head disengage from the slot, the screwing mechanism also includes a guide plate, which is fixedly mounted on the processing box. The guide plate is a folding plate. When the left-turning tube drives the adjusting inner rod to move in the direction of the driving bevel gear, the adjusting inner rod will be squeezed by the guide plate, thereby causing the adjusting inner rod to move to the left, and then the adjusting inner rod drives the clamping head to disengage from the slot through the connecting rod.

[0022] Further technical solution: A second partition is also provided inside the processing box, and the second partition is "L"-shaped. The second partition encloses the driving mechanism and the screwing mechanism in a corner of the processing box. The left-turning pipe will pass through the second partition. A movable gap for the movement of the left-turning pipe is opened on the second partition. An elastic sealing membrane is provided between the left-turning pipe and the movable gap to prevent quenching oil and water vapor from entering the interior of the second partition.

[0023] Further technical solution: A first partition is provided inside the processing box, which divides the interior of the processing box into a preheating chamber and a main heating chamber. A material guide port for connecting the preheating chamber and the main heating chamber is opened on the side of the first partition. The material guide port is located above the oil outlet pipe, and heating pipes are provided in both the preheating chamber and the main heating chamber.

[0024] A further technical solution includes a pretreatment tank, which is arranged on one side of the treatment box, a feed pipe is provided on the side of the pretreatment tank, a drain pipe is provided on the bottom of the pretreatment tank, an oil collecting pipe is connected to the top of the pretreatment tank, an oil return pipe is connected to the side of the oil collecting pipe, and one end of the oil return pipe is connected to the preheating chamber in the treatment box;

[0025] After the raw material processing is completed, in order to avoid residual quenching oil in the pretreatment tank, an oil drain branch pipe is connected to the side of the pretreatment tank, one end of which is connected to the return oil pipe. A valve is provided on the oil drain branch pipe, and initially, the valve is closed.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention provides a water-permeable membrane. When the quenching oil is heated to above 120 degrees Celsius, the water in the raw material will vaporize and the quenching oil will float out. The water vapor can pass through the water-permeable membrane, but the water-permeable membrane will block the passage of the quenching oil, thereby preventing the quenching oil from floating out with the water vapor and avoiding the waste of quenching oil.

[0028] 2. The present invention is provided with an oil film removal mechanism, which can remove the oil film at the bottom of the water permeable membrane, thereby preventing the water permeable membrane from being blocked by the oil film, which in turn leads to a decrease in the water flow rate of the water permeable membrane and avoids a decrease in the working efficiency of the device;

[0029] 3. The present invention provides a gear and a rack. When the drive mechanism drives the concentric tube to move, the concentric tube also drives the gear to move. The gear rolls along the rack, which in turn causes the gear to drive the concentric tube to rotate. The concentric tube then drives the oil suction cylinder to roll, causing different parts of the oil suction cylinder to contact the bottom of the water-permeable membrane. This can increase the oil absorption capacity of the oil suction cylinder and avoid the reduction of the oil removal effect caused by saturation of a certain part of the oil suction cylinder.

[0030] 4. The present invention is provided with a screwing and squeezing mechanism. After the oil-absorbing strips store a large amount of quenching oil, the screwing and squeezing mechanism squeezes the insides of the oil-absorbing strips against each other to squeeze out the quenching oil absorbed therein. This not only avoids a reduction in the oil absorption capacity of the oil-absorbing cylinder, but also avoids waste of quenching oil. At the same time, compared with the prior art, in which workers disassemble the processing box to clean the oil film removal mechanism, the present invention can save a lot of time, manpower and material resources and improve work efficiency.

[0031] 5. The present invention provides a first baffle so that the raw materials are preheated in the preheating chamber before entering the main heating chamber from the material guide port. The main heating chamber heats all the water in the quenching oil therein to a vaporized state, while the low-temperature quenching oil in the mixing area at the bottom of the preheating chamber is driven upward by the subsequent raw materials and then enters the main heating chamber. This avoids the continuous mixing of low-temperature and high-temperature raw materials, which results in the water in this area being unable to evaporate and the subsequent reduction in the quality of the quenching oil.

[0032] 6. The present invention provides a pretreatment tank. When the treated water in the raw material is more than the quenching oil, the raw material can be first introduced into the pretreatment tank, and the preliminary deposited water and quenching oil can be separated in the pretreatment tank. This step can remove most of the deposited water, thereby improving the efficiency of removing suspended water and emulsified water when the raw material is heated and evaporated.

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0045] like Figures 1-9 As shown, a quenching oil separator provided by the present invention includes a processing box 1, a feeding port is provided on the side of the processing box 1, an oil outlet pipe 2 is provided on the other side of the processing box 1, the top of the processing box 1 is connected to a collection cover 3, and the top of the collection cover 3 is connected to a steam pipe 4;

[0046] A water-permeable membrane 8 is installed inside the processing box 1. The collection cover 3 and the oil outlet pipe 2 are located on both sides of the water-permeable membrane 8. The water-permeable membrane 8 is a nanofiltration membrane (pore size 1 nm). Water vapor can pass through the water-permeable membrane 8, but the water-permeable membrane 8 will prevent the quenching oil from passing through.

[0047] A heating pipe 9 is further provided inside the treatment box 1. The heating pipe 9 is located below the water-permeable membrane 8. When raw materials (quenching oil containing water) are introduced into the treatment box 1, the raw materials are submerged above the top of the heating pipe 9. The heating pipe 9 heats the raw materials to a temperature above 120 degrees Celsius, causing the water in the raw materials to vaporize and release the quenching oil. One end of the steam pipe 4 is then connected to an exhaust fan, which extracts the water vapor, thereby separating the quenching oil and water.

[0048] Since quenching oil is a non-polar substance and is incompatible with the hydrophilic surface of the water-permeable membrane 8 (such as a polyamide membrane), the oil molecules will be repelled and gathered on the membrane surface to form an oil film. The oil film will prevent water vapor from passing through the water-permeable membrane 8, thereby reducing the water flow rate of the water-permeable membrane 8. Therefore, an oil removal membrane mechanism 7 is also installed inside the processing box 1. The output end of the oil removal membrane mechanism 7 is in contact with the bottom of the water-permeable membrane 8. The oil removal membrane mechanism 7 is used to remove the oil film at the bottom of the water-permeable membrane 8 to prevent the water-permeable membrane 8 from being blocked by the oil film, which in turn leads to a reduction in the water flow rate of the water-permeable membrane 8, thereby improving the working efficiency of the device.

[0049] The present invention provides a quenching oil separator. In this embodiment, the oil removal film mechanism 7 includes two sliders 74 slidably mounted inside the processing box 1. The processing box 1 is provided with a slide rail 75 adapted to the slider 74. A concentric tube is rotatably mounted between the two sliders 74. Abutment rollers 77 are fixedly mounted at both ends of the concentric tubes. The oil removal film mechanism 7 also includes a plurality of oil absorption strips 71. The two ends of all the oil absorption strips 71 are respectively fixedly connected to the back ends of the two abutment rollers 77. The plurality of oil absorption strips 71 are evenly distributed around the abutment rollers 77. The plurality of oil absorption strips 71 form an oil absorption cylinder. The oil absorption strips 71 are made of an elastic and relatively elastic oil-absorbing cotton material, such as polyurethane (PU) sponge, silicone modified cotton, etc. The surface of the oil absorption cylinder contacts the bottom of the water-permeable membrane 8.

[0050] The oil film removal mechanism 7 further includes a driving mechanism 79 , which is installed inside the processing box 1 . The output end of the driving mechanism 79 is connected to one end of the concentric tube, and the driving mechanism 79 is used to drive the left-turning tube 712 to move horizontally.

[0051] When the water-permeable membrane 8 is being deoiled, the driving mechanism 79 drives the concentric tube to move horizontally, and the concentric tube drives the abutment roller 77 and the oil suction cylinder to move. The oil suction cylinder will scrape and absorb the oil film on the bottom of the water-permeable membrane 8, thereby preventing the oil film from clogging the water-permeable membrane 8, avoiding the reduction of the water flow rate of the water-permeable membrane 8, and improving the efficiency of separating quenching oil and water.

[0052] The present invention provides a quenching oil separator. In this embodiment, the driving mechanism 79 includes a driving block 791 and a second motor 793. The driving block 791 is rotatably mounted at one end of the concentric tube, and the second motor 793 is fixedly mounted inside the processing box 1. The output shaft of the second motor 793 is fixedly connected to a screw 792, and one end of the screw 792 is threadedly connected to the driving block 791.

[0053] The present invention provides a quenching oil separator. Since the friction coefficient of quenching oil is low, when the concentric tube drives the oil suction cylinder to move, even if the concentric tube is rotated, the oil suction cylinder may not roll along the bottom of the water-permeable membrane 8, and it may always move horizontally, causing the same part of the oil suction cylinder to always contact the bottom of the water-permeable membrane 8, and then causing the same part of the oil suction cylinder to always absorb quenching oil. When the quenching oil adsorbed by this part reaches saturation, it will no longer absorb quenching oil, and then the oil absorption capacity of the oil suction cylinder will be reduced, resulting in a decrease in the oil film removal effect of the oil suction cylinder. Therefore, in this embodiment, gears are installed at both ends of the concentric tube, and two racks 72 adapted to the two gears are fixedly connected to the interior of the processing box 1, and the racks 72 are meshed with the gears.

[0054] When the driving mechanism 79 drives the concentric tube to move, the concentric tube will also drive the gear to move, and the gear will roll along the rack 72, which will then cause the gear to drive the concentric tube to rotate. The concentric tube then drives the oil suction cylinder to roll, so that different parts of the oil suction cylinder contact the bottom of the water-permeable membrane 8, and then the oil absorption capacity of the oil suction cylinder can be increased, avoiding the reduction of the oil removal film effect caused by saturation of a certain part of the oil suction cylinder.

[0055] The quenching oil separator provided by the present invention has a large amount of quenching oil stored in the oil absorption strip 71 after long-term use. This not only reduces the oil absorption capacity of the oil absorption strip 71 but also wastes the quenching oil. In this case, the staff needs to disassemble the processing box 1, replace the oil absorption strip 71, and recover the quenching oil in the oil absorption strip 71. This process not only requires stopping the operation of the device, resulting in reduced work efficiency, but also wastes a lot of manpower, material resources and time. Therefore, in this embodiment, the oil film removal mechanism 7 also includes a screwing mechanism 78;

[0056] Specifically, the concentric tubes include a disconnected right-turn tube 76 and a left-turn tube 712, which are rotatably mounted on two sliders 74 respectively. An adjusting inner rod 711 is inserted into the left-turn tube 712, and one end of the adjusting inner rod 711 is fixedly connected to a connecting rod 718. The interior of the right-turn tube 76 is fixedly connected to an inner fixing block 715, and one end of the connecting rod 718 passes through the inner fixing block 715 and is fixedly connected to a clamping head 719. A clamping groove 716 adapted to the clamping head 719 is provided on the side of the inner fixing block 715 near the clamping head 719. The interior of the right-turn tube 76 is fixedly connected to a limiting ring 717, and a return spring 720 is connected between the inner fixing block 715 and the limiting ring 717.

[0057] To prevent the meshing of the gear and rack 72 from affecting the rotation of the left-turn tube 712, the two gears are a movable gear 710 and a fixed gear 73. The fixed gear 73 is fixedly mounted on the right-turn tube 76, and the movable gear 710 is slidably mounted on the left-turn tube 712. The movable gear 710 is fixedly connected to the adjustment inner rod 711 via a connecting column. A sliding hole 714 is opened on the side of the left-turn tube 712 for the movement of the connecting column.

[0058] The driving block 791 is rotatably mounted on one end of the left-turn tube 712;

[0059] The output end of the screwing and squeezing mechanism 78 is connected to one end of the left-turning tube 712 , and the screwing and squeezing mechanism 78 is used to drive the left-turning tube 712 to rotate.

[0060] When in use, the driving mechanism 79 drives the left-turning tube 712 to move horizontally, and the left-turning tube 712 drives the right-turning tube 76 to move horizontally synchronously by adjusting the inner rod 711 and the connecting rod 718. Initially, under the elastic force of the return spring 720, the clamping head 719 is clamped into the clamping groove 716, thereby preventing the right-turning tube 76 and the left-turning tube 712 from being radially misaligned, which would cause the oil absorption strip 71 to be twisted, and then reduce the contact area between the oil absorption strip 71 and the water-permeable membrane 8, thereby avoiding a reduction in the oil absorption capacity of the oil absorption cylinder;

[0061] When the quenching oil in the oil-absorbing strip 71 needs to be squeezed out, the adjusting inner rod 711 is first moved to the left to disengage the clamping head 719 from the clamping groove 716. At the same time, the adjusting inner rod 711 drives the movable gear 710 to move through the connecting column, so that the movable gear 710 and the rack 72 are disengaged, so that the left-turning tube 712 can rotate freely relative to the right-turning tube 76. Then the screwing mechanism 78 drives the left-turning tube 712 to rotate, and the left-turning tube 712 drives one end of the oil-absorbing strip 71 to rotate through the abutting roller 77. Since the fixed gear 73 is always engaged with the rack 72, the right-turning tube 76 is 6 will be fixed on the processing box 1, then the left-turning tube 712 rotates relative to the right-turning tube 76, so that one end of all the oil-absorbing strips 71 are twisted and entangled with each other. Since the distance between the two abutting rollers 77 remains unchanged, the oil-absorbing strips 71 will be stretched, and the diameter of the oil-absorbing strips 71 will be reduced. The insides of the oil-absorbing strips 71 are squeezed against each other, and the quenching oil absorbed in the oil-absorbing strips 71 can be squeezed out, thereby avoiding the reduction of the oil absorption capacity of the oil suction cylinder. At the same time, through the automatic oil squeezing mechanism, there is no need for the staff to disassemble the processing box 1, which saves a lot of time, manpower and material resources and improves work efficiency.

[0062] After the oil is squeezed out, the screwing mechanism 78 is disengaged from the left-turning tube 712. Under the action of the elasticity of the oil-absorbing strip 71 itself, the oil-absorbing strip 71 drives the abutting roller 77 and the left-turning tube 712 to return to their original state. Then, the adjusting inner rod 711 moves to the right, so that the clamping head 719 is clamped into the clamping groove 716 again, and the oil-absorbing cylinder can remove the oil film on the water-permeable membrane 8 again.

[0063] The present invention provides a quenching oil separator. In this embodiment, the screwing and squeezing mechanism 78 includes a driven bevel gear 781 and a telescopic rod 782. The driven bevel gear 781 is fixedly mounted on the left-turning tube 712. The telescopic rod 782 is fixedly mounted inside the processing box 1. The movable end of the telescopic rod 782 is fixedly mounted with a first motor 783. The output shaft of the first motor 783 is fixedly connected to a driving bevel gear 784. The driving bevel gear 784 can mesh with the driven bevel gear 781.

[0064] After the oil suction cylinder is saturated, the left-turning pipe 712 is transported to the bottom of the driving bevel gear 784 by the driving mechanism 79, and then the telescopic rod 782 drives the first motor 783 and the driving bevel gear 784 to descend, so that the driving bevel gear 784 and the driven bevel gear 781 are engaged, and the first motor 783 can drive the left-turning pipe 712 to rotate through the driving bevel gear 784 and the driven bevel gear 781;

[0065] In order to make the clamping head 719 disengage from the slot 716, the screwing mechanism 78 also includes a guide plate 785, which is fixedly mounted on the processing box 1. The guide plate 785 is a folding plate. When the left-turning tube 712 drives the adjusting inner rod 711 to move toward the driving bevel gear 784, the adjusting inner rod 711 will be squeezed by the guide plate 785, thereby causing the adjusting inner rod 711 to move to the left, and then the adjusting inner rod 711 drives the clamping head 719 to disengage from the slot 716 through the connecting rod 718.

[0066] The present invention provides a quenching oil separator. In order to prevent the driving mechanism 79 and the screwing mechanism 78 from being affected by quenching oil and water vapor, in this embodiment, a second partition 6 is further provided inside the processing box 1. The second partition 6 is "L"-shaped. The second partition 6 seals the driving mechanism 79 and the screwing mechanism 78 at a corner of the processing box 1. The left-turning pipe 712 will pass through the second partition 6. A movable seam 713 is provided on the second partition 6 for the left-turning pipe 712 to move. An elastic sealing membrane is provided between the left-turning pipe 712 and the movable seam 713 to prevent quenching oil and water vapor from entering the interior of the second partition 6.

[0067] The present invention provides a quenching oil separator. When continuously separating quenching oil and water, low-temperature raw materials will continue to flow into the processing box 1, and they will mix with the high-temperature quenching oil, thereby causing the temperature of the quenching oil to drop. When the temperature is not enough to convert water into water vapor, water will remain in the quenching oil. Since low-temperature raw materials will continue to flow into this area, the water in this area will not be able to evaporate, which will lead to a decrease in the quality of the quenching oil. Therefore, in this embodiment, a first partition 5 is provided inside the processing box 1. The first partition 5 divides the interior of the processing box 1 into a preheating chamber and a main heating chamber. A material guide port 10 for connecting the preheating chamber and the main heating chamber is provided on the side of the first partition 5. The material guide port 10 is located above the oil outlet pipe 2. A heating pipe 9 is provided in both the preheating chamber and the main heating chamber.

[0068] Specifically, the raw materials are passed into the preheating chamber, which preheats the raw materials. The preheated raw materials enter the main heating chamber from the material guide port 10. The main heating chamber heats all the water in the quenching oil therein to an evaporating state, and the low-temperature quenching oil in the mixing area at the bottom of the preheating chamber will be driven to the top by the subsequent raw materials and then enter the main heating chamber, thereby avoiding the residue of raw materials and improving the quality of the quenching oil.

[0069] In order to prevent quenching oil from remaining in the preheating chamber, an oil drain pipe connected to the preheating chamber is provided on the side of the processing box 1. A valve is provided on the oil drain pipe, and the valve is normally closed. When no raw materials enter the preheating chamber subsequently, the preheating chamber will become the main heating chamber. The water vapor generated in the preheating chamber will enter the main heating chamber from the material guide port 10, and then be extracted by the steam pipe 4. The remaining quenching oil can be discharged from the oil drain pipe.

[0070] The present invention provides a quenching oil separator. When processing raw materials with more water than quenching oil (such as wastewater used to flush quenching oil on the surface of quenched parts), the device cannot operate continuously due to the high water content. In this embodiment, it also includes a pretreatment tank 11, which is arranged on one side of the treatment box 1. A feed pipe 13 is provided on the side of the pretreatment tank 11. A drain pipe 12 is provided at the bottom of the pretreatment tank 11. The top of the pretreatment tank 11 is connected to an oil collecting pipe 14. The side of the oil collecting pipe 14 is connected to an oil return pipe 15. One end of the oil return pipe 15 is connected to the preheating chamber in the treatment box 1.

[0071] After the raw material processing is completed, in order to avoid residual quenching oil in the pretreatment tank 11, an oil drain branch pipe 16 is connected to the side of the pretreatment tank 11, one end of the oil drain branch pipe 16 is connected to the return oil pipe 15, and a valve is provided on the oil drain branch pipe 16. Initially, the valve is closed.

[0072] The raw materials are continuously fed into the pretreatment tank 11 from the feed pipe 13. After the raw materials enter the pretreatment tank 11, the quenching oil will quickly float above the water. Under the pressure of the subsequent raw materials, the quenching oil enters the return oil pipe 15 from the oil collecting pipe 14, and then enters the preheating chamber.

[0073] After the raw materials are used up and the subsequent pressure is insufficient to allow the quenching oil to enter the return oil pipe 15, the valve on the oil drain branch pipe 16 can be opened, and then the water in the pretreatment tank 11 and the quenching oil will enter the treatment box 1 together and then be processed.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0075] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
