Description

Technical Field

[0001] The invention belongs to the technical field of steam dewaxing kettle, in particular to a wax model dewaxing device. Background Art

[0002] Wax casting is also called lost wax casting. It is mainly used to manufacture metal products with complex shapes. The wax mold is made into a wax model according to the object to be cast. The wax mold is then fixed on a bracket and coated with multiple layers of ceramic slurry to form a hard shell. The shell is then heated to melt and discharge the wax mold inside, leaving a cavity, which is the dewaxing operation of the wax mold.

[0003] The prior art also proposes some solutions. For example, a patent application with publication number CN116748469A discloses a steam dewaxing kettle, including a steam generator; a dewaxing kettle is installed on the steam generator; a liquid inlet pipe is connected to the steam generator, and a liquid discharge pipe and an exhaust pipe are connected to the dewaxing kettle, and a waste heat utilization mechanism matching the liquid inlet pipe, the liquid discharge pipe and the exhaust pipe is arranged on the outside of the steam generator; by recovering the heat of the waste gas and waste liquid for preheating the liquid inlet, the temperature of the water input into the steam dewaxing kettle is increased, and the energy consumption when heating the water to steam is reduced, it is easy to ensure that the heat of the waste liquid and the waste gas is fully utilized.

[0004] The dewaxing operation in the prior art is to place the wax mold together with the shell mold in a dewaxing kettle, and then introduce high-temperature steam into the dewaxing kettle to heat the wax mold in the shell mold. During this process, the shell mold needs to be placed upside down in the dewaxing kettle so that the molten wax can flow out of the shell mold. However, since the structure of some shell molds is relatively complex, some wax liquid will still remain in the shell mold.

[0005] To this end, the present invention provides a wax pattern dewaxing device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a wax model dewaxing device described in the present invention comprises a kettle body; the outside of the kettle body is fixedly connected to a furnace body; the cavity between the furnace body and the kettle body is a steam generating chamber; a steam generating assembly is installed in the steam generating chamber; the steam generating assembly is used to heat the water introduced into the steam generating chamber into a high-pressure steam state, and then introduce it into the kettle body; a wax liquid collecting assembly is installed on the bottom surface of the inner part of the kettle body; the wax liquid collecting assembly is used to collect wax liquid; a pair of rotating rings are rotatably connected to the inside of the kettle body, and the two rotating rings are respectively located at the two ends of the kettle body; a pair of connecting plates are fixedly connected between the two rotating rings; a bearing assembly is commonly provided on the top surfaces of the two connecting plates; the bearing assembly is used to place the wax model to be dewaxed; a driving assembly is fixedly connected to the end of the furnace body away from its opening; the driving assembly is used to drive the rotating ring to rotate; an outer shell is fixedly connected to the outside of the furnace body, and the outer shell wraps the furnace body and the kettle body; a sealing door is installed on the surface of the outer shell at the opening of the kettle body; an exhaust pipe is fixedly connected to the top surface of the outer shell, and the exhaust pipe is connected to the inside of the furnace body; A solenoid valve is installed on the shell; when working, when dewaxing the wax mold, in order to reduce the residual wax liquid in the shell mold, the embodiment of the present invention can be used. First, the user needs to open the sealing door at one end of the shell, and then place the shell mold to be dewaxed and the wax mold inside it on the supporting component. Then the user needs to close the sealing door and the exhaust pipe, and then introduce high-temperature steam into the kettle body through the steam generating component in the steam generating chamber. After the high-temperature steam is introduced into the shell, the high-temperature steam will transfer heat to the wax mold inside the shell mold, and then the wax mold will be melted by the heat and discharged from the bottom of the shell mold. The wax liquid flows to the wax collection component through the opening, and then the driving component drives the rotating ring to rotate back and forth, so that the connecting plate and the shell mold on the rotating ring also swing along the inner wall of the kettle body, and then the residual wax liquid in the shell mold is thrown out of the shell mold through centrifugal action, so as to ensure the cleanliness of the shell mold and avoid the influence of wax residue on subsequent production. At the same time, as much wax liquid as possible can be recovered to avoid waste of wax liquid. Then the exhaust pipe exhausts the air to release the high-temperature steam in the kettle body, so that the temperature inside the kettle body can no longer scald the user, and then the user can open the sealed door to take out the shell mold after the wax is removed.

[0008] Preferably, the driving assembly comprises a connecting tube; the connecting tube is fixedly connected between the furnace body and the kettle body, and the connecting tube is communicated with the inside of the kettle body; the rotating ring near the connecting tube is fixedly connected with a connecting arm at its center; the end of the connecting arm away from the center of the rotating ring is fixedly connected with a driving rod, and the driving rod is telescopically arranged; the driving rod is located inside the connecting tube, and the end near the kettle body is connected to the connecting tube through a rotating seal; the end of the driving rod near the furnace body is fixedly connected with a sealing ring, and the inner diameter of the sealing ring is larger than the driving rod; the surface of the driving rod is fixedly connected with a sealing gasket, and the diameter of the sealing gasket is larger than the inner diameter of the sealing ring; a motor is fixedly connected to the inside of the shell at the corresponding position of the driving rod; the motor is connected to the driving rod through a telescopic coupling; when working When the rotating ring needs to be driven to rotate, the motor will drive the driving rod to rotate, and then the driving rod will drive the connecting arm, the rotating ring, the connecting plate and the receiving assembly to swing along the inner wall of the kettle body. At this time, the driving rod is connected through the rotating seal between it and the connecting pipe. When the rotating seal is damaged, high-temperature steam will flow into the connecting pipe and push the sealing gasket on the surface of the driving rod, so that the sealing gasket moves toward the sealing ring, and finally the sealing gasket fits with the sealing ring, thereby completing the sealing of the connecting pipe and preventing high-temperature steam from leaking from the end of the connecting pipe close to the motor, causing high-temperature steam to diffuse inside the outer shell, causing the user to be scalded when touching the outer shell, or damaging the instrument inside the shell, thereby avoiding major losses and leaving time for the user to stop and replace the machine.

At this time, one end of the connecting frame has already extended out of the kettle body, and since the bottom of the end extending out of the kettle body is not supported by the connecting plate, the connecting frame at this end will tilt downward due to its own gravity, and then the connecting frame has a tendency to deflect, and at this time the limiting plate will pull the end of the connecting frame that is still located inside the kettle body, thereby limiting the deflection of the connecting frame and preventing the connecting frame from deflecting and tilting, which will cause the supporting basket on the connecting frame to directly slide off and cause damage.

[0012] Preferably, the top surface of the connecting frame on one side away from each other is rotatably connected with a buckle plate; the top surface of the buckle plate is fixedly connected with a cover plate; a slot is opened on the surface of the cover plate at the position corresponding to the roller; the slot is adapted to the roller; during operation, when the user pushes the connecting frame and the carrying basket into the kettle body, the user needs to flip the buckle plate so that the buckle plate is buckled on the side surface of the connecting plate, and the cover plate at the end of the buckle plate will cover the top surface of the connecting frame, and the roller at the bottom of the carrying basket will also be located in the slot on the surface of the cover plate, thereby restricting the roller and the carrying basket to prevent the carrying basket from separating from the connecting frame when the connecting frame and the carrying basket shake along the inner wall of the kettle body.

First, the user needs to open the sealing door 7 at one end of the shell, and then place the shell mold to be dewaxed and the wax mold inside it on the supporting component. Then the user needs to close the sealing door 7 and the exhaust pipe 8, and then introduce the high-temperature steam into the kettle body 1 through the steam generating component in the steam generating chamber 3. After the high-temperature steam is introduced into the shell, the high-temperature steam will transfer heat to the wax mold inside the shell mold, and then the wax mold will melt due to the heat and be discharged from the bottom of the shell mold. The wax liquid flows to the wax collection component through the opening, and then the driving component drives the rotating ring 4 to rotate back and forth, so that the connecting plate 5 and the shell mold on the rotating ring 4 also swing along the inner wall of the kettle body 1, and then the residual wax liquid in the shell mold is thrown out of the shell mold through centrifugal action, so as to ensure the cleanliness of the shell mold and avoid the influence of the residual wax liquid on the subsequent production. At the same time, as much wax liquid as possible can be recovered to avoid the waste of wax liquid. Then the exhaust pipe 8 exhausts the air to release the high-temperature steam in the kettle body 1, so that the temperature inside the kettle body 1 can no longer scald the user, and then the user can open the sealing door 7 to take out the shell mold after the wax is removed.

[0033] like Figure 1 , Figure 2 and Figure 8As shown, the driving assembly includes a connecting pipe 9; the connecting pipe 9 is fixedly connected between the furnace body 2 and the kettle body 1, and the connecting pipe 9 is communicated with the inside of the kettle body 1; the rotating ring 4 near the connecting pipe 9 is fixedly connected with a connecting arm 10 at its center; the end of the connecting arm 10 away from the center of the rotating ring 4 is fixedly connected with a driving rod 11, and the driving rod 11 is retractable; the driving rod 11 is located inside the connecting pipe 9, and the end near the kettle body 1 is connected to the connecting pipe 9 through a rotating seal; the end of the driving rod 11 near the furnace body 2 is fixedly connected with a sealing ring 12, and the inner diameter of the sealing ring 12 is larger than the driving rod 11; the surface of the driving rod 11 is fixedly connected with a sealing gasket 13, and the diameter of the sealing gasket 13 is larger than the inner diameter of the sealing ring 12; a motor 14 is fixedly connected to the corresponding position of the driving rod 11 inside the housing 6; the motor 14 is connected to the driving rod 11 through a retractable coupling When the rotating ring 4 needs to be driven to rotate, the motor 14 will drive the driving rod 11 to rotate, and then the driving rod 11 will drive the connecting arm 10, the rotating ring 4, the connecting plate 5 and the receiving assembly to swing along the inner wall of the kettle body 1. At this time, the driving rod 11 is connected through the rotating seal between it and the connecting pipe 9. When the rotating seal is damaged, the high-temperature steam will flow into the connecting pipe 9 and push the sealing gasket 13 on the surface of the driving rod 11, so that the sealing gasket 13 moves toward the sealing ring 12, and finally the sealing gasket 13 fits with the sealing ring 12, thereby completing the sealing of the connecting pipe 9, avoiding high-temperature steam from leaking from the end of the connecting pipe 9 close to the motor 14, causing high-temperature steam to diffuse inside the outer shell 6, causing the user to be scalded when touching the outer shell 6, or damaging the instrument inside the shell, thereby avoiding major losses while leaving time for the user to stop and replace.

[0034] like Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, the bearing assembly includes a connecting frame 15, and the connecting frame 15 is slidably connected to the connecting plate 5; the top surface of the connecting frame 15 is provided with limiting grooves 16 at both sides; the limiting grooves 16 are inclined near the opening of the kettle body 1; the bottom of the limiting grooves 16 is rotatably connected to a plurality of rollers 18 evenly arranged; the top surface of the connecting frame 15 is provided with a bearing basket 17; the bottom surface of the bearing basket 17 is hollowed out; the bottom surface of the bearing basket 17 is rotatably connected to the roller 18; the position of the roller 18 corresponds to the limiting groove 16, and the roller 18 is adapted to the limiting groove 16; during operation, when the user needs to put the shell mold to be dewaxed into the kettle body 1, the user opens the sealing door 7, Pull the connecting frame 15 on the connecting plate 5 out of the kettle body 1, then remove the upper carrying basket 17 of the connecting frame 15, and put the shell mold to be dewaxed in the carrying basket 17, and then place the carrying basket 17 on the top of the cart, and then push the cart to the connecting frame 15 outside the kettle body 1, and then the user pushes the receiving basket to make the roller 18 at the bottom of the receiving basket slide toward the limiting groove 16, and finally enter the top of the connecting frame 15 along the limiting groove 16, and then the user can move the cart, and then push the connecting frame 15 and the carrying basket 17 into the kettle body 1.

At this time, the limiting plate 21 will pull the end of the connecting frame 15 that is still located inside the kettle body 1, thereby limiting the deflection of the connecting frame 15 and preventing the connecting frame 15 from deflecting and tilting, causing the supporting basket 17 on the connecting frame 15 to directly slide off and cause damage.

[0036] like Figure 5As shown, the inner walls of the two connecting plates 5 on one side close to each other are fixedly connected with guide buckets 22; the bottom surfaces of the two guide buckets 22 are fixedly connected with guide pipes 23; the two guide pipes 23 are respectively located on both sides of the limit block 19; during operation, when the wax liquid in the shell mold flows out, the wax liquid will flow into the guide bucket 22 along the hollow at the bottom of the carrying basket 17, and then flow into the guide pipe 23 from the guide bucket 22. Since the guide pipes 23 are located on both sides of the limit block 19, the wax liquid will flow from both sides of the limit block 19 to the inner wall of the kettle body 1, thereby preventing the wax liquid from flowing directly to the surface of the limit block 19, and further preventing the wax liquid from solidifying in the chute 20, which causes the movement of the limit plate 21 to be obstructed.

[0037] like Figure 4 , Figure 5 and Figure 7 As shown, the top surface of the connecting frame 15 that is away from each other is rotatably connected with a buckle plate 24; the top surface of the buckle plate 24 is fixedly connected with a cover plate 25; a slot 26 is opened on the surface of the cover plate 25 at the position corresponding to the roller 18; the slot 26 is adapted to the roller 18; during operation, when the user pushes the connecting frame 15 and the carrying basket 17 into the interior of the kettle body 1, the user needs to flip the buckle plate 24 so that the buckle plate 24 is buckled on the side surface of the connecting plate 5, at this time, the cover plate 25 at the end of the buckle plate 24 will cover the top surface of the connecting frame 15, and the roller 18 at the bottom of the carrying basket 17 will also be located in the slot 26 on the surface of the cover plate 25, thereby restricting the roller 18 and the carrying basket 17 to prevent the carrying basket 17 from separating from the connecting frame 15 when the connecting frame 15 and the carrying basket 17 are shaking along the inner wall of the kettle body 1.

[0038] like Figure 4 , Figure 5 and Figure 7As shown, the top surfaces of the two connecting plates 5 and the sides away from each other are inlaid with hydraulic pipes 27; the ends of the hydraulic pipes 27 close to the sealing door 7 are slidably connected with pressure rods 28; a spring 29 is fixedly connected between the pressure rod 28 and the hydraulic pipe 27; the interior of the hydraulic pipe 27 is filled with hydraulic fluid; a plurality of uniformly arranged push rods 30 are slidably arranged on the top surface of the hydraulic pipe 27; during operation, when the user closes the sealing door 7, the sealing door 7 will squeeze the pressure rod 28 at the end of the hydraulic pipe 27, press the pressure rod 28 toward the hydraulic pipe 27, and compress the spring 29, thereby pushing the hydraulic oil in the hydraulic pipe 27 to push the hydraulic The push rod 30 at the top of the tube 27 is lifted up, and the push rod 30 will push against the surface of the buckle plate 24, so that the buckle plate 24 buckles toward the side surface of the connecting frame 15, thereby driving the cover plate 25 to cover the top surface of the connecting frame 15, and then completing the fixation of the roller 18 at the bottom of the receiving basket, thereby eliminating the need for manual operation by the user, thereby reducing the difficulty of operation for the user, and after the sealing door 7 is opened, the pressure rod 28 can also be restored under the drive of the spring 29, so that the push rod 30 is retracted into the hydraulic tube 27, and the user can now flip the buckle plate 24 normally to unlock the locking effect of the cover plate 25 and the slot 26 on the roller 18.

[0039] like Figure 4 , Figure 5 and Figure 7 As shown, a plurality of evenly arranged spring grooves 31 are provided on both sides of the supporting basket 17; a spring 2 32 is fixedly connected to the bottom of the spring groove 31; and a push plate 33 is fixedly connected to one end of the spring 2 32 away from the bottom of the spring groove 31; during operation, when the push rod 30 pushes the buckle plate 24 to move toward the side wall of the connecting frame 15, the buckle plate 24 will squeeze the push plate 33, so that the push plate 33 moves toward the bottom of the spring groove 31 and compresses the spring 2 32. When the user opens the sealing door 7, the push rod 30 is retracted to the end of the hydraulic pipe 27, and the compressed spring 2 32 is restored, thereby pushing the buckle plate 24 away from the connecting frame 15, and then driving the cover plate 25 away from the connecting frame 15, so that after the sealing door 7 is opened, the lock of the receiving basket roller 18 is automatically released, thereby further facilitating the user to draw out the receiving basket.

[0040] like Figure 1 and Figure 8As shown, the wax liquid collection assembly includes a collection box 34; the collection box 34 is embedded in the bottom surface of the kettle body 1; a wax discharge pipe 35 is fixedly connected to the bottom of the collection box 34, and the wax discharge pipe 35 extends to the outside of the shell 6; a pair of brush plates 36 are fixedly connected between the two rotating rings 4 near the bottom position; an electromagnetic valve is installed inside the wax discharge pipe 35; during operation, when the driving rod 11 drives the rotating ring 4 to rotate, the rotating ring 4 will also drive the brush plate 36 between them to swing back and forth along the inner wall of the kettle body 1, thereby scraping the inner wall of the kettle body 1, so that the wax liquid on the inner wall of the kettle body 1 is scraped into the collection box 34, and then it can be discharged from the wax discharge pipe 35 according to the needs of the user, thereby achieving the reduction of wax liquid waste while improving the recovery efficiency of the collection box 34.

[0041] like Figure 1 and Figure 8 As shown, a plurality of uniformly arranged heating rods 37 are fixedly connected near the bottom of the collecting box 34; the heating rods 37 are connected to an external power source; during operation, when the exhaust pipe 8 has completed exhausting, the user can start the heating rods 37 to heat the wax liquid in the collecting box 34, thereby evaporating the water in the wax liquid, so as to facilitate the subsequent recovery and reuse of the wax liquid.

[0042] During operation, when dewaxing the wax mold, in order to reduce the residual wax liquid in the shell mold, the embodiment of the present invention can be used. First, the user needs to open the sealing door 7 at one end of the shell, and then place the shell mold to be dewaxed and the wax mold inside it on the supporting component. Then, the user needs to close the sealing door 7 and the exhaust pipe 8, and then introduce the high-temperature steam into the kettle body 1 through the steam generating component in the steam generating chamber 3. After the high-temperature steam is introduced into the shell, the high-temperature steam will transfer heat to the wax mold inside the shell mold, and then the wax mold will melt due to the heat, and flow from the opening at the bottom of the shell mold to the inner side of the shell mold. The wax liquid collecting component and then the driving component drive the rotating ring 4 to rotate back and forth, so that the connecting plate 5 and the shell mold on the rotating ring 4 also swing along the inner wall of the kettle body 1, and then the residual wax liquid in the shell mold is thrown out of the shell mold through centrifugal action, so as to ensure the cleanliness of the shell mold and avoid the influence of the residual wax liquid on the subsequent production. At the same time, as much wax liquid as possible can be recovered to avoid the waste of wax liquid. Then the exhaust pipe 8 exhausts the air to release the high-temperature steam in the kettle body 1, so that the temperature inside the kettle body 1 can no longer scald the user, and then the user can open the sealing door 7 to take out the shell mold after the wax is removed.

[0043] When it is necessary to drive the rotating ring 4 to rotate, the motor 14 will drive the driving rod 11 to rotate, and then the driving rod 11 will drive the connecting arm 10, the rotating ring 4, the connecting plate 5 and the receiving assembly to swing along the inner wall of the kettle body 1. At this time, the driving rod 11 is connected to the connecting pipe 9 through the rotating seal between it and the connecting pipe 9. When the rotating seal is damaged, high-temperature steam will flow into the connecting pipe 9 and push the sealing gasket 13 on the surface of the driving rod 11, so that the sealing gasket 13 moves toward the sealing ring 12, and finally the sealing gasket 13 fits with the sealing ring 12, thereby completing the sealing of the connecting pipe 9 and preventing high-temperature steam from leaking from the end of the connecting pipe 9 close to the motor 14, causing high-temperature steam to diffuse inside the outer shell 6, causing the user to be scalded when touching the outer shell 6, or damaging the instrument inside the shell, thereby avoiding major losses while leaving time for the user to stop and replace.

[0044] When the user needs to put the shell mold to be dewaxed into the kettle body 1, the user opens the sealing door 7, pulls the connecting frame 15 on the connecting plate 5 out of the kettle body 1, and then removes the upper carrying basket 17 of the connecting frame 15, and puts the shell mold to be dewaxed in the carrying basket 17, and then places the carrying basket 17 on the top of the cart, and then pushes the cart to the connecting frame 15 outside the kettle body 1, and then the user pushes the receiving basket to make the roller 18 at the bottom of the receiving basket slide toward the limiting groove 16, and finally enters the top of the connecting frame 15 along the limiting groove 16, and then the user can move the cart, and then push the connecting frame 15 and the carrying basket 17 into the kettle body 1. By pulling the connecting frame 15 out of the kettle body 1, the user does not need to extend his body into the kettle body 1 when loading materials, thereby further protecting the life and health of the user.

[0045] When the user pulls the connecting frame 15 out of the kettle body 1, the limiting plate 21 will be pulled inside the connecting frame 15, and the limiting plate 21 will move with the connecting frame 15 to the opening of the kettle body 1. At this time, one end of the connecting frame 15 has extended out of the kettle body 1, and because the bottom of the end extending out of the kettle body 1 is not supported by the connecting plate 5, the connecting frame 15 at this end will tilt downward due to its own gravity, and then the connecting frame 15 will tend to deflect. At this time, the limiting plate 21 will pull the end of the connecting frame 15 that is still located inside the kettle body 1, thereby limiting the deflection of the connecting frame 15 and preventing the connecting frame 15 from deflecting and tilting, which will cause the supporting basket 17 on the connecting frame 15 to directly slide off and cause damage.

[0046] When the wax liquid in the shell mold flows out, the wax liquid will flow into the guide bucket 22 along the hollow at the bottom of the carrying basket 17, and then flow into the guide pipe 23 from the guide bucket 22. Since the guide pipe 23 is located on both sides of the limit block 19, the wax liquid will flow from both sides of the limit block 19 to the inner wall of the kettle body 1, thereby preventing the wax liquid from flowing directly to the surface of the limit block 19, and further preventing the wax liquid from solidifying in the chute 20, which would cause the movement of the limit plate 21 to be obstructed.

[0047] After the user pushes the connecting frame 15 and the carrying basket 17 into the interior of the kettle body 1, the user needs to flip the buckle plate 24 so that the buckle plate 24 buckles on the side surface of the connecting plate 5. At this time, the cover plate 25 at the end of the buckle plate 24 will cover the top surface of the connecting frame 15, and the roller 18 at the bottom of the carrying basket 17 will also be located in the groove 26 on the surface of the cover plate 25, thereby restricting the roller 18 and the carrying basket 17 to prevent the carrying basket 17 from separating from the connecting frame 15 when the connecting frame 15 and the carrying basket 17 shake along the inner wall of the kettle body 1.

[0048] When the user closes the sealing door 7, the sealing door 7 will squeeze the pressure rod 28 at the end of the hydraulic pipe 27, press the pressure rod 28 toward the hydraulic pipe 27, and compress the spring 29, thereby pushing the hydraulic oil in the hydraulic pipe 27 to lift the push rod 30 at the top of the hydraulic pipe 27, and the push rod 30 will push against the surface of the buckle plate 24, so that the buckle plate 24 buckles to the side surface of the connecting frame 15, thereby driving the cover plate 25 to cover the top surface of the connecting frame 15, and then completes the fixation of the roller 18 at the bottom of the receiving basket, thereby eliminating the need for manual operation by the user, thereby reducing the difficulty of operation for the user, and after the sealing door 7 is opened, the pressure rod 28 can also be restored under the drive of the spring 29, so that the push rod 30 is retracted into the hydraulic pipe 27, and the user can now normally flip the buckle plate 24 to unlock the locking effect of the cover plate 25 and the slot 26 on the roller 18.

[0049] When the push rod 30 pushes the buckle plate 24 to move toward the side wall of the connecting frame 15, the buckle plate 24 will squeeze the push plate 33, so that the push plate 33 moves toward the bottom of the spring groove 31 and compresses the spring 2 32. When the user opens the sealing door 7, the push rod 30 is retracted to the end of the hydraulic pipe 27, and the compressed spring 2 32 is restored, thereby pushing the buckle plate 24 away from the connecting frame 15, and then driving the cover plate 25 away from the connecting frame 15, so that after the sealing door 7 is opened, the lock of the receiving basket roller 18 is automatically released, thereby further facilitating the user to draw out the receiving basket.

[0050] When the driving rod 11 drives the rotating ring 4 to rotate, the rotating ring 4 will also drive the brush plate 36 between them to swing back and forth along the inner wall of the kettle body 1, thereby scraping the inner wall of the kettle body 1, so that the wax liquid on the inner wall of the kettle body 1 is scraped into the collecting box 34, and then it can be discharged from the wax discharge pipe 35 according to the needs of the user, thereby achieving the recovery efficiency of the collecting box 34 while reducing the waste of wax liquid.

[0051] The wax liquid is heated to evaporate the water in the wax liquid so that the wax liquid can be recovered and reused later.
