Description

Technical Field

[0001] The utility model belongs to the technical field of non-stick pan preparation devices, and particularly relates to a salt bath nitriding treatment device for preparing nitride non-stick pans. Background Art

[0002] Nitriding is a process that introduces nitrogen into a material to form a nitride layer. The nitriding process is usually used to improve the hardness, wear resistance and corrosion resistance of the material. During the salt bath nitriding process, the material is immersed in a salt bath containing nitriding salts and nitriding agents, and then heated to an appropriate temperature. The nitrogen will diffuse into the surface of the material at high temperature and form a nitride layer on the surface of the material.

[0003] At present, when performing salt bath nitriding treatment on non-stick pans, the pre-treated pan body is usually immersed directly in the salt bath. Since the pan body placed in the salt bath cannot change its own placement, some parts of the pan body may not be properly nitrided during the salt bath nitriding, affecting the overall corrosion resistance of the pan body. In addition, since the shape of the pan body is fixed, the concentration of nitride around the pan body will decrease after a period of nitriding treatment, thereby affecting the stable progress of the salt bath nitriding treatment. At the same time, it is also inconvenient to quickly take and place the salt bath nitrided pan body, affecting the treatment efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 6 The embodiments are described in detail.

[0021] This embodiment provides a salt bath nitriding treatment device for preparing nitride non-stick pans, as shown in the attached Figure 1-6As shown, it includes a barrel body 1 and a sealing cover 2. A heating component that can heat the inside of the barrel body 1 is provided on the outside of the barrel body 1. The heating component includes a U-shaped insulation plate 7 that can be attached to the outer periphery of the bottom of the barrel body 1, a circular insulation plate 8 and an electric heating plate 9 fixedly connected to both sides of the barrel body 1. The U-shaped insulation plate 7 and the circular insulation plate 8 are fixedly installed with an electric heating plate 9 inside. The electric heating plate 9 has various types, such as stainless steel electric heating plates, ceramic electric heating plates, cast aluminum electric heating plates, etc., which are existing well-known technologies and will not be elaborated on here. The number of U-shaped insulation plates 7 is several and several U-shaped insulation plates 7 are equidistantly fixed on the outer surface of the barrel body 1. After the U-shaped insulation plate 7 and the electric heating plate 9 inside the circular insulation plate 8 are energized, they can fully heat the surroundings of the barrel body 1, so that the temperature required for nitriding treatment is reached in the barrel body 1.

[0022] An electric lifting rod 3 is fixedly installed on one side of the barrel body 1, and the top of the movable rod body of the electric lifting rod 3 is provided with a right-angle bracket 4 that can be inserted into the barrel body 1. One side of the top of the right-angle bracket 4 is fixedly connected to a fixed plate 10. Electric lifting rods 3 are provided on both sides of the lower surface of the fixed plate 10, and the fixed rod parts of the two electric lifting rods 3 are fixedly installed at both ends of the same side of the barrel body 1. The lifting of the movable rod parts of the two electric lifting rods 3 can drive the fixed plate 10 to rise and fall, thereby driving the right-angle bracket 4 to rise and fall, making it convenient to put the pot on the placement rack 6 into the barrel body 1 or take it out of the barrel body 1;

[0023] The bottom of the right-angle bracket 4 is provided with a swing mechanism which can be movable relative to it, and the top of the swing mechanism is rotatably connected to an electric push rod 5. The electric lifting rod 3, the electric push rod 5 and the electric heating plate 9 are all electrically connected to the external circuit through wires. The fixed rod body part of the electric push rod 5 is hinged to one side of the top of the right-angle bracket 4, and the top of the swing mechanism is rotatably connected to the movable rod body of the electric push rod 5. The swing mechanism includes a rotating rod 11, a swing rod 12, a connecting frame 13 and a connecting plate 14. The rotating rod 11 is rotatably connected to the bottom of the side of the right-angle bracket 4 and the swing rod 12 is fixedly connected to one end of the rotating rod 11 close to the inner wall of the barrel body 1. The number of rotating rods 11 and swing rods 12 is several, and several rotating rods 11 are equidistantly and evenly connected to the bottom of the side of the right-angle bracket 4 in a laterally rotatable manner, and the tops of several swing rods 12 are rotatably connected to the inside of the connecting frame 13. The connecting plate 14 is fixedly connected to the middle part of the upper surface of the connecting frame 13 and is rotatably connected to the movable rod body of the electric push rod 5.

[0024] The bottom of the swing mechanism is evenly and fixedly connected to a plurality of placement racks 6 for placing and fixing the pot body. The number of the placement racks 6 is the same as the number of the rotating rods 11, and the plurality of placement racks 6 are respectively fixedly connected to the ends of the plurality of rotating rods 11 away from the swing rod 12. The placement rack 6 consists of an outer ring for fixing the pot body, a bottom ring for receiving the bottom of the pot, and a right-angle plate for fixing the two. The four sides of the bottom ring are fixedly connected to the outer ring by right-angle plates. The plurality of placement racks 6 are vertically and equidistantly arranged inside the barrel body 1.

[0025] In the initial state, the movable rod body of the electric push rod 5 extends half its length. At this time, the connecting frame 13 below is in a horizontal state and the swing arm 12 is in a vertical state. When the movable rod body of the electric push rod 5 is pushed outward, the connecting plate 14 and the connecting frame 13 can be pushed to move to the side away from the electric push rod 5, and the rotating rod 11 at the bottom of the swing arm 12 is rotatably connected to the bottom of the right-angle bracket 4. Therefore, the rotating rod 11 can only rotate inside the right-angle bracket 4. When the electric push rod 5 drives the swing arm 12 to tilt to one side through the connecting frame 13, since the electric push rod 5 is hinged at the top of the right-angle bracket 4, it itself will also rotate relatively with respect to the right-angle bracket 4. Therefore, one end of the movable rod body of the electric push rod 5 will gradually tilt downward as the swing arm 12 tilts, which can ensure that the movable rod body of the electric push rod 5 can move normally between each structure when it is extended outward or retracted inward.

[0026] When the movable rod body of the electric push rod 5 drives the swing rod 12 to tilt through the connecting frame 13, the multiple placement racks 6 at the bottom can be moved synchronously, so that the openings of the placement racks 6 face obliquely upward; and when the movable rod body of the electric push rod 5 is retracted inward, the swing rod 12 is driven by the connecting frame 13 to tilt toward the side close to the electric push rod 5, the multiple placement racks 6 at the bottom can be rotated synchronously to a state where the openings face obliquely downward, and the pot body is driven by the electric push rod 5 to circulate back and forth, which can stir the salt bath solution in the barrel body 1, so that the nitride content of each part inside it is kept uniform, ensuring normal nitriding treatment of the pot body; When the rack 6 and the pot body are in a state where the opening is facing obliquely downward, the pot body at the rear may slide out from the rack 6, while the bottom ring and the right-angle plate of the front rack 6 can just support the pot body at the rear, preventing the pot body at the rear from completely sliding out of the rack 6. At the same time, after the pot body slides outward a small part, the part of its outer surface that initially fits in with the rack 6 is also exposed to the salt bath solution, so that the entire pot body can be more fully salt-bath nitrided. When the front end of the pot body tilts obliquely downward and slides outward, the top of the opening edge abuts against the inner wall of the barrel body 1, thereby preventing the front end of the pot body from sliding out of the rack 6.

[0027] The sealing cover 2 is hinged on one side of the top of the barrel body 1 and can be sealed on the top of the barrel body 1. When the sealing cover 2 is sealed on the top of the barrel body 1, a groove is provided at the position corresponding to the right-angle bracket 4, which is adapted to the right-angle bracket 4. The groove can be clamped on the outside of the right-angle bracket 4 and can ensure the tightness of the connection between the two, so as to prevent the gas in the barrel body 1 from being discharged outward from the right-angle bracket 4. The upper surface of the sealing cover 2 is provided with a filling hole 15 for filling the barrel body 1 and an exhaust hole 16 for discharging harmful gases. The outside of the filling hole 15 is sealed. The sealing connection is provided with a sealing cover. When the pot body is subjected to salt bath nitriding treatment, the operator can regularly detect the nitride content of the salt bath solution in the barrel body 1. When the content is reduced, the salt bath solution can be added to the barrel body 1 through the injection hole 15, thereby ensuring that the pot body is fully subjected to salt bath nitriding treatment; the exhaust hole 16 is connected to the external gas pipeline. Harmful gas will be generated when the pot body is subjected to salt bath nitriding treatment. The exhaust hole 16 can facilitate the discharge of the harmful gas, thereby preventing the harmful gas from being directly emitted into the air and affecting the health of the operator.

[0028] In summary, the salt bath nitriding treatment device for preparing nitride non-stick pans has the following steps:

[0029] 1. Use the electric lifting rod 3 to push the placement rack 6 out of the barrel 1, and inject a salt bath solution that can completely immerse the pot body into the barrel 1, and then place the pot body into the placement rack 6 respectively;

[0030] 2. Then, the placement rack 6 is lowered into the barrel 1 by the electric lifting rod 3 and the pot body is completely immersed in the salt bath solution. The sealing cover 2 is closed and the barrel 1 is heated by the heating component to perform nitriding treatment on the pot body in the salt bath solution.

[0031] 3. Control the movable rod part of the electric push rod 5 to extend and retract cyclically, which can drive the placement rack 6 and the pot body to swing cyclically through the swing mechanism, so that the pot body can be nitrided more fully and the nitriding efficiency can be improved;

[0032] 4. After the nitriding is completed, the sealing cover 2 is opened, and the placement rack 6 and the pot body are both in a horizontal state with the opening facing horizontally to ensure that the salt bath solution does not accumulate in the pot body. Then, the pot body is removed from the salt bath solution by the electric lifting rod 3 to complete the nitriding treatment of the pot body.

[0033] The above description is only for the purpose of illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the scope of protection of the present invention.
