Description

Technical Field

[0001] The present application relates to the technical field of surface treatment of light alloy cookware, and in particular to a treatment device and a treatment process for ceramicizing the surface of a light alloy cookware. Background Art

[0002] Traditional cookware manufacturing industry usually uses stainless steel and aluminum alloy to make cookware. Stainless steel and aluminum alloy have their own advantages and disadvantages in cookware applications. Although stainless steel has good corrosion resistance, it contains a large amount of "Cr" elements. Long-term use of frying, stir-frying, cooking, deep-frying, and corrosion by liquids such as salt and acid will inevitably cause trace precipitation of certain chemical elements; although aluminum alloy cookware does not contain certain heavy metal ions, aluminum ions are harmful to human health, and aluminum alloy has poor corrosion resistance. Therefore, Teflon coating is generally used in aluminum alloy cookware to improve its corrosion resistance, but Teflon can also volatilize harmful elements at high temperatures. Therefore, with the improvement of people's living standards and the increasing attention to health and environmental issues, stainless steel cookware and aluminum alloy cookware can no longer meet people's usage needs.

[0003] In recent years, technicians in the cookware manufacturing industry have developed new types of composite metal cookware, which are made of stainless steel, aluminum alloy or titanium alloy. The inner layer of the cookware is aluminum alloy or titanium alloy, and the outer layer of the cookware is stainless steel. However, due to the low hardness and poor wear resistance of aluminum alloy and titanium alloy, it is easy to cause abrasions or scratches during use. In addition, aluminum pots are prone to corrosion and aluminum ions are easily free, which affects human health.

[0004] At present, there are many methods for treating the surface hardness, wear resistance and corrosion resistance of aluminum alloy or titanium alloy, including spraying ceramic coating, PVD (physical vapor deposition) coating, electroplating, laser surface treatment, nano coating, anodizing, etc. Among them: spraying ceramic coating and PVD coating both have the problems of complex process and high cost; although the electroplating process is relatively mature and the cost is relatively low, the adhesion to aluminum alloy is insufficient, the coating may peel off, and the wear resistance is relatively poor; although the laser surface treatment has high processing accuracy and can achieve local strengthening, the equipment cost is high and the technical requirements are high; although the nano coating has a small film thickness and will not affect the weight and appearance of the pot, it has certain requirements for the adhesion and durability of the coating, and the process cost is high; anodizing can form an oxide film on the surface to improve the wear resistance and corrosion resistance. Its treatment process can be found in the Chinese invention patent CN113622010B, which discloses a black ceramic film on the surface of an aluminum alloy and a preparation method thereof. During the treatment process, the aluminum alloy object needs to be placed in an electrolyte for oxidation treatment, but this method is not suitable for composite pots with stainless steel outer surfaces.

[0005] It can be seen that the existing methods for surface hardness, wear resistance and corrosion resistance treatment of aluminum alloys or titanium alloys are difficult to meet the process and cost requirements for new composite metal cookware in production practice, resulting in high cost and limited treatment effect of the surface treatment process of new composite metal cookware. Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the invention

[0027] Furthermore, in step S4, the power supply has a touch screen, and electrical parameters are set through the touch screen, and the electrical parameters include current density, duty cycle, frequency and final voltage.

[0028] Compared with the prior art, this application has at least the following beneficial effects:

[0029] 1. The present application provides a light alloy cookware ceramic treatment device, which supports and installs the cookware through the anode pot ring on the cookware support and flipping mechanism, and realizes the flipping of the cookware through a rotating shaft and a pushing assembly. After the cookware is flipped and the electrolyte in the cookware is poured out, it can be flipped and reset again. The device arranges a cathode assembly directly above the cookware. During the treatment process, the distance between the cathode assembly and the bottom of the cookware is maintained at 30mm to 35mm. The electrolyte in the liquid storage tank below the cookware is pumped into the cookware through a circulating pump, so that the electrolyte overflows from the edge of the cookware, the anode pot ring is electrically connected to the positive electrode of the power supply, and the cathode assembly is electrically connected to the negative electrode of the power supply, that is, the anode pot ring, the electrolyte and the cathode assembly constitute a ceramic system, which can form a layer of titanium oxide or aluminum oxide ceramic film on the inner surface of the cookware. Therefore, when using the device provided in the present application to ceramicize light alloy cookware, there is no need to immerse the entire cookware in the electrolyte, and there is no need to seal the outer surface of the cookware. It is only necessary to inject the electrolyte into the pot and place the cathode. When using the present device to ceramicize light alloy cookware, the treatment process is simple, the electric field is not scattered during the treatment process, the energy utilization rate is high, and the overall structure of the device is simple, and the manufacturing, installation, and use and maintenance costs are all low.

[0030] 2. The pot support and flipping mechanism in the present application not only provides a support and installation position for the pot to be processed, but also provides an electrolytic anode for the ceramicization system, and realizes the formation of a ceramic film on the inner surface of the pot by means of an external anode pot ring. At the same time, the pot support and flipping mechanism in the present application also realizes the convenient dumping of the electrolyte in the pot through the structural design of the pot placement rack, the rotating shaft and the pushing assembly.

[0031] 3. In the present application, the top of the cathode assembly is connected to the support frame, which not only supports the installation but also realizes the electrical connection between the cathode assembly and the power supply through the conductive unit thereon. The support frame can be detachably installed above the cookware, or can be directly connected to the lifting device. When installing or removing the cookware, the support frame can be lifted to avoid installation interference. After the cookware is installed, the support frame is driven to descend, so that a gap of 30mm to 35mm is formed between the bottom of the cathode assembly and the bottom of the cookware to be processed, as well as between the bottom edge of the cathode assembly and the inner wall of the cookware to be processed, to form a ceramic system. The lifting device can improve the overall automation level of the device, improve production efficiency, reduce personnel participation, and reduce personnel costs.

[0032] 4. In the present application, a partition is set up in the liquid storage tank, and the edge of the pot to be treated located on the anode pot ring is lower than the edge of the liquid storage tank. In specific application practice, the installation height of the partition in the liquid storage tank can be designed according to the depth of the pot and the length of the cathode assembly. Preferably, when the support plate is overlapped on the edge of the liquid storage tank, a gap of 30mm to 35mm is formed between the bottom of the cathode assembly and the bottom of the pot to be treated.

[0033] 5. The present application provides threaded fastening holes and fastening screws on the anode pot ring so as to fix the pot tightly on the anode pot ring, thereby ensuring the connection stability between the pot and the anode pot ring and ensuring the stability of the pot during the flipping process.

[0034] 6. In the present application, a flow regulating valve is arranged on the liquid delivery pipe at the outlet end of the circulation pump, and the flow regulating valve can be used to adjust the appropriate electrolyte flow rate according to processing needs.

[0035] 7. The present application provides a light alloy cookware ceramic treatment process, which adopts the above-mentioned light alloy cookware ceramic treatment device. When using this treatment process to ceramicize light alloy cookware, there is no need to immerse the entire cookware in an electrolyte, and there is no need to seal the outer surface of the cookware. It is only necessary to inject the electrolyte into the pot and place the cathode. During the treatment process, the electric field is not scattered, the energy utilization rate is high, and the production cost is low.

[0051] In order to solve the problem of poor wear resistance of existing composite metal cookware, the inventor proposed that the inner surface of the composite metal cookware can be ceramicized. The method of surface ceramicizing aluminum alloy in traditional technology is to put the aluminum alloy object into an electrolyte for oxidation treatment, and then wash and dry the aluminum alloy object after oxidation treatment. However, this method is not suitable for new composite metal cookware. The inner layer of the new cookware is aluminum alloy or titanium alloy, and the outer layer of the cookware is stainless steel. Although aluminum alloy or titanium alloy can react with electrolyte to form a ceramic film, the surface of stainless steel cannot generate an oxide film with ceramic properties and consumes a lot of electricity, affecting the treatment effect. In addition, different materials may induce different electrochemical reactions during the electrolysis process, resulting in mutual influence between the inner layer and the outer layer, affecting the quality of the final ceramic layer. Therefore, in order to ensure the treatment effect, it is not appropriate to directly immerse this new composite metal cookware in the electrolyte for ceramic treatment.

[0052] In order to ceramicize the inner surface of a composite metal cookware while ensuring the treatment effect, the present application provides a light alloy cookware ceramicization treatment device and a treatment process.

[0053] Embodiment 1

[0054] The present embodiment provides a light alloy cookware ceramic treatment device that can be used in the light alloy cookware ceramic treatment process. When using this device to perform light alloy cookware ceramic treatment, there is no need to immerse the cookware in electrolyte, and there is no need to seal the outer surface of the cookware. It is only necessary to inject electrolyte into the cooker and place a suitable cathode. During the treatment process, the electric field is not scattered, the energy utilization rate is high, the production cost is low, and a layer of titanium oxide or aluminum oxide ceramic film can be grown in situ in the cookware.

[0055] The light alloy cookware ceramic treatment device provided in this embodiment mainly includes a liquid storage tank 1, a cookware support and flip mechanism 3, a cathode structure assembly 4, a power supply 6 and a circulation pump 5. Among them: the liquid storage tank 1 is used to contain electrolyte, and the electrolyte used for surface ceramic treatment of aluminum alloy or titanium alloy is the prior art. A partition 2 for mounting the cookware support and flip mechanism 3 is arranged above the electrolyte level in the liquid storage tank 1; the cookware support and flip mechanism 3 includes a cookware placement rack 31, a rotating shaft 34 and a push assembly 33. The cookware placement rack 31 is rotatably connected with the bracket on the partition 2 through the rotating shaft 34 (a bearing seat can be arranged on the bracket, and the rotating shaft can be installed in the bearing seat, and the bracket can be two oppositely arranged vertical plates welded on the partition 2), one end of the push assembly 33 is connected to the partition 2, and the other end is connected to the edge of the cookware placement rack 31. The cookware placement rack 31 can be flipped through the rotating shaft 34 and the push assembly 33, that is, the push assembly 33 can be telescopic to push the cookware placement rack 31 to flip around the rotating shaft 34. A mounting groove is provided on the side of the pot placement rack 31 away from the electrolyte surface, and a circle of anode pot ring 32 is arranged at the notch of the mounting groove. The pot 8 to be processed is placed on the anode pot ring 32, and the anode pot ring 32 is electrically connected to the positive pole of the power supply 6; the cathode structure assembly 4 includes a cathode assembly 41 arranged directly above the pot 8 to be processed, and the cathode assembly 41 is electrically connected to the negative pole of the power supply 6. A gap of 30 mm to 35 mm is formed between the bottom of the cathode assembly 41 and the bottom of the pot 8 to be processed, such as Figure 1 , 2 The circulation pump 5 is used to pump the electrolyte in the liquid storage tank 1 to the pot 8 to be processed, and the liquid storage tank 1 is used to receive the electrolyte overflowing from the edge of the pot 8 to be processed.

[0056] It can be seen that the device supports and installs the pot through the anode pot ring 32 on the pot support and turning mechanism 3, and arranges the cathode assembly 41 directly above the pot, and the distance between the cathode assembly 41 and the bottom of the pot is maintained at 30mm to 35mm. The electrolyte in the liquid storage tank 1 below the pot is pumped into the pot by the circulation pump 5, so that the electrolyte overflows from the edge of the pot, the anode pot ring 32 is electrically connected to the positive electrode of the power supply 6, and the cathode assembly 41 is electrically connected to the negative electrode of the power supply 6, that is, the anode pot ring 32, the electrolyte and the cathode assembly 41 constitute a ceramic system, which can form a layer of titanium oxide or aluminum oxide ceramic film on the inner surface of the pot.

[0057] In order to further improve the ceramic treatment effect, in addition to ensuring that the bottom of the cathode assembly 41 is 30mm to 35mm away from the bottom of the pot, it is also necessary to ensure that the bottom edge of the cathode assembly 41 is 30mm to 35mm away from the inner wall of the pot. Such a distance setting can avoid the appearance of spots in the film formation and shorten the time required for film formation. Therefore, in a specific manufacturing example, the structural dimensions of the cathode assembly are adapted to the size of the pot to be treated. Large-sized pots are equipped with large-sized cathode assemblies, and small-sized pots are equipped with small-sized cathode assemblies. Figure 1 A circle of cathode extension plates can be set on the side wall of the cathode assembly 41 near its bottom. When cathode assemblies of different sizes are made corresponding to cookware of different sizes, the target distance (30mm to 35mm) between the bottom edge of the cathode assembly and the inner wall of the cookware can be ensured by changing the diameter of the cathode extension plates.

[0058] In this embodiment, see Figure 1 The cathode structure assembly 4 further includes a support frame 42, which is mounted on the top of the cathode assembly 41, and a conductive unit capable of electrically connecting the cathode assembly 41 and the negative electrode of the power source 6 is provided on the support frame 42, and the support frame 42 can play a supporting and electrically conductive role.

[0059] In specific application practice, the cathode assembly 41 can be installed directly above the pot by the support frame 42. For example, a mounting seat is provided above the device, and the support frame 42 is detachably mounted on the mounting seat. The height of the mounting seat can be designed to adapt to the depth of the pot and the height of the cathode structure assembly 4. Preferably, when the support frame 42 is installed on the mounting seat, a gap of 30 mm to 35 mm is formed between the bottom of the cathode assembly 41 and the bottom of the pot 8 to be processed. When the pot needs to be placed or removed, the support frame 42 only needs to be removed from the mounting seat. The executor for removing the support frame 42 from the mounting seat or installing the support frame 42 on the mounting seat can be a staff member or an industrial robot.

[0060] In one embodiment, see Figure 1 The support frame 42 can be connected to the lifting device 7, and the cathode assembly 41 can be driven to rise and fall above the pot 8 to be processed by the lifting device 7. For example, an electrically driven lifting device 7 can be arranged beside the device, and the lifting device 7 includes a vertical lifting telescopic part and a horizontal connecting part connected to the top of the lifting telescopic part. The support frame 42 can be installed on the horizontal connecting part of the lifting device 7, and the vertical distance between the bottom of the cathode assembly 41 and the bottom of the pot 8 to be processed can be adjusted by the lifting device 7.

[0061] In this embodiment, see Figure 1 The rotating shaft 34 is horizontally installed on the pot placement rack 31, and the pot 8 to be processed is located above the rotating shaft 34. The rotating shaft 34 is eccentrically set on the pot placement rack 31. When the pushing assembly 33 is extended or retracted, the pot placement rack 31 can be driven to flip around the rotating shaft 34 as the center, and the electrolyte in the pot is introduced into the liquid storage tank 1 below.

[0062] In this embodiment, the pushing assembly 33 includes a pneumatic telescopic rod, which is installed on the partition. The output end of the pneumatic telescopic rod is connected to the edge of the pot placement rack 31. When the output end of the pneumatic telescopic rod is extended, it can drive the pot placement rack 31 to flip around the rotating shaft 34 as the rotation center, so that the pot on the pot placement rack 31 is flipped and the electrolyte in the pot is poured into the liquid storage tank 1. When the output end of the pneumatic telescopic rod is retracted, it can drive the pot placement rack 31 to reset.

[0063] In other embodiments, the above-mentioned push assembly can be any retractable structure, such as an electric push rod or a hydraulic cylinder.

[0064] It can be seen that the present application realizes the convenient dumping of the electrolyte in the pot through the structural design of the pot placement rack 31, the rotating shaft 34 and the push assembly 33. Since the liquid reservoir 1 is arranged below the pot support and flipping mechanism 3, the electrolyte poured out from the pot can directly flow into the liquid reservoir 1 to realize the recycling of the electrolyte. Of course, in order to ensure that the electrolyte poured out from the pot can flow into the liquid reservoir 1, naturally, the partition 2 in the present application must be provided with holes that allow the electrolyte to flow out. In the specific production, the partition 2 in the present application can directly use a steel structure frame. The steel structure frame can not only ensure the structural strength to support the installation of the pot support and flipping mechanism, but also has a large area of ​​gaps, through which the electrolyte can also flow directly into the liquid reservoir 1.

[0065] In this embodiment, continue to refer to Figure 1 , the partition 2 only needs to be higher than the electrolyte level, therefore, the partition 2 can be installed in the liquid storage tank 1, so that the edge of the pot to be treated 8 located on the anode pot ring 32 is lower than the edge of the liquid storage tank 1. In specific application practice, the installation height of the partition 2 in the liquid storage tank 1 can be designed according to the depth of the pot and the length of the cathode assembly 41. Preferably, when the support plate falls on the edge of the liquid storage tank 1, a gap of 30mm to 35mm is formed between the bottom of the cathode assembly 41 and the bottom of the pot to be treated 8.

[0066] In this embodiment, in order to ensure the installation stability of the pot, the anode pot ring 32 is provided with a plurality of threaded fastening holes for installing fastening screws, and the outer wall of the pot to be treated 8 is tightly fixed to the end of the fastening screws.

[0067] In this embodiment, the circulation pump 5 is used to pump the electrolyte in the liquid storage tank 1 into the cooker. Therefore, the inlet end of the circulation pump 5 is connected to the liquid outlet on the liquid storage tank 1, and the outlet end of the circulation pump 5 is connected to a liquid delivery pipe. The discharge port of the liquid delivery pipe is located above the cooker 8 to be processed. A flow regulating valve can be provided on the liquid delivery pipe, and the flow regulating valve can be used to adjust the appropriate electrolyte flow rate according to processing needs.

[0068] By using the light alloy cookware ceramicization treatment device provided in the present application, the inner surface of the light alloy cookware can be ceramicized on the basis of ensuring the treatment effect, thereby strengthening the hardness of the inner surface of the light alloy cookware and further improving the wear resistance of the inner layer of the cookware. In addition, the overall structure of the device is simple, and the manufacturing, installation, use and maintenance costs are low. The treatment process for ceramicization treatment using the device is simple, which reduces the production difficulty and production cost.

[0069] Embodiment 2

[0070] This embodiment provides a light alloy cookware ceramic treatment process. The light alloy cookware ceramic treatment device provided in the above embodiment 1 can be used in this treatment process. The processing steps of this treatment process are described below:

[0071] S1: The cleaned and dried pot to be processed 8 is fastened and mounted on the anode pot ring 32 of the pot placement rack 31;

[0072] S2: adjusting the vertical height of the cathode structure assembly 4 so that a gap of 30 mm to 35 mm is formed between the bottom of the cathode assembly 41 and the bottom of the pot 8 to be treated;

[0073] S3: starting the circulation pump 5 to pump the electrolyte into the pot to be treated 8, so that the electrolyte in the pot to be treated 8 overflows from the pot edge;

[0074] S4: Start the power supply 6, set the electrical parameters and processing time;

[0075] S5: After the treatment is completed, the circulation pump 5 and the power supply 6 are turned off, the cathode structure assembly 4 is lifted, and the push assembly 33 is started to flip the pot, so that the electrolyte in the pot flows into the liquid storage tank 1, and then the pot is flipped and reset;

[0076] S6: Take out the processed pots and pans and wash and dry them.

[0077] In the above step S1 , the cleaned and dried pot 8 to be processed is fixed tightly to the anode pot ring 32 by fastening screws to ensure that the pot is in good contact with the anode pot ring 32 .

[0078] In the above step S2, the anode pot ring 32 is electrically connected to the "+" pole of the power supply 6, and the cathode assembly 41 is electrically connected to the "-" pole of the power supply 6 through the conductive unit. The vertical height of the cathode structure assembly 4 can be adjusted by the lifting device 7. The cathode assembly 41 falls to the center position in the pot under the action of the lifting device 7, and the gap between the cathode assembly 41 and the bottom of the pot is adjusted to about 30mm to 35mm. At the same time, a gap of 30mm to 35mm is also formed between the bottom edge of the cathode assembly and the inner wall of the pot to be treated.

[0079] In the above step S3, after starting the circulation pump 5, the flow rate can be adjusted to a suitable level through the flow control valve so that the electrolyte can evenly flow out from the edge of the pot and fall into the liquid storage tank 1 below the pot. During the process, the temperature of the electrolyte pumped into the pot to be treated 8 must be ensured to be lower than 40°C.

[0080] In some specific application practices, the existing electrolyte cooling system can be used to control the temperature of the electrolyte during the treatment process, so that the temperature range of the electrolyte pumped into the pot to be treated is 25°C to 35°C, and the maximum does not exceed 40°C.

[0081] In the above step S4, before starting the power supply, check whether the device and the pot have any abnormalities. If there is no abnormality, restart the power supply. The power supply has a touch screen, and the staff can set the electrical parameters through the touch screen. The electrical parameters include current density, duty cycle, frequency and final voltage.
