Description

Technical Field

[0001] The utility model belongs to the technical field of gas nitriding furnace processing, and particularly relates to an anti-oxidation structure of a gas nitriding furnace. Background Art

[0002] A nitriding furnace is a type of heat treatment equipment that uses ammonia and nitrogen as reactive gases to react at high temperatures, nitriding the surface of a material, thereby changing the physical and chemical properties of the material. Nitriding furnaces perform functions such as nitriding, reduction, and carbonization. Their primary purpose is to improve a material's hardness, corrosion resistance, lubricity, and electrical properties, while also enhancing its load-bearing capacity and ductility, while also improving product quality and performance.

[0003] In order to improve the service life of the gas nitriding furnace during use, an anti-oxidation coating is sprayed on the surface of the gas nitriding furnace through an anti-oxidation structure during the production of the gas nitriding furnace to improve the oxidation resistance of the gas nitriding furnace. However, in the process of spraying the gas nitriding furnace, the existing anti-oxidation structure generally uses an extraction pump to draw the coating into the spray pipe, and then a plurality of nozzles spray the coating on the surface of the gas nitriding furnace. During the spraying process, the coating will be in a static state, and the coating will precipitate during the long-term static state, which will lead to a decrease in the concentration of antioxidants in other parts of the coating, thereby making the antioxidant performance unevenly distributed. After the spraying is completed, the surface of the sprayed layer will fall off, affecting the antioxidant performance. Utility Model Content

[0004] The purpose of the utility model is to provide a gas nitriding furnace anti-oxidation structure with a simple structure and reasonable design in order to solve the above problems.

A storage box is installed on the top of the base plate, and the inside of the storage box is rotatably connected to a rotating rod, and the outside of the rotating rod is rotatably connected to a plurality of stirring rods.

[0007] As a further optimization solution of the present invention, an annular opening is provided on one side of the annular box close to the fixed column, a cavity is provided inside the fixed column, and a plurality of feed holes are provided between the cavity and the annular opening.

[0008] As a further optimization scheme of the present invention, the spray assembly includes a spray pipe located on the processing table, a plurality of nozzles installed on one side of the spray pipe, and a connecting pipe installed on the outside of the annular box and used to connect the annular box with the spray pipe, one end of the connecting pipe is fixedly connected to the outside of the annular box.

[0009] As a further optimization scheme of the present invention, a first driven wheel is installed on the outside of the annular box, a driving wheel engaged with the first driven wheel is installed on the top of the support platform, one end of the rotating rod extends to the top of the support platform and is installed with a second driven wheel engaged with the first driven wheel, and a rotating motor that drives the driving wheel to rotate is installed at the bottom of the support platform.

[0010] As a further optimization solution of the present invention, a high-pressure pump is installed on the top of the base plate, the inlet of the high-pressure pump is connected to the storage box through a liquid inlet pipe, and the outlet of the high-pressure pump is connected to the cavity through a liquid outlet pipe.

[0011] As a further optimization solution of the present invention, a heat preservation box with a ring structure is installed on the outside of the storage box, and a plurality of heating pipes are installed inside the heat preservation box.

[0012] The beneficial effect of the present invention is that during the process of spraying the outside of the gas nitriding furnace, the rotating rod inside the storage box will rotate.

[0019] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figure 1 - Figure 5 The figure shows an anti-oxidation structure of a gas nitriding furnace, comprising a base plate 1, a plurality of support plates 2 mounted on the top of the base plate 1, and a support platform 3 mounted on the top of the plurality of support plates 2, a fixed column 4 mounted on the top of the support platform 3, a processing platform 5 mounted on the top of the fixed column 4, an annular box 6 is rotatably connected to the outside of the fixed column 4, an annular opening 10 is provided on the side of the annular box 6 close to the fixed column 4, a cavity 11 is provided inside the fixed column 4, a plurality of feed holes 12 are provided between the cavity 11 and the annular opening 10, two groups of spraying components are installed on the outside of the annular box 6, the spraying components include a spray pipe 13 located on the processing table 5, a plurality of nozzles 14 mounted on one side of the spray pipe 13, and a connecting pipe 21 mounted on the outside of the annular box 6 and used to connect the annular box 6 with the spray pipe 13, one end of the connecting pipe 21 is fixedly connected to the outside of the annular box 6, a storage box 7 is mounted on the top of the base plate 1, the interior of the storage box 7 is rotatably connected to a rotating rod 8, the outside of the rotating rod 8 is rotatably connected to a plurality of stirring rods 9, and the storage box 7 is provided with a plurality of An annular insulation box 19 is installed on the outside, and multiple annular heating pipes 20 are installed inside the insulation box 19. In winter, the heating pipes 20 can heat the paint inside the storage box 7 to prevent the paint close to the outer wall of the storage box 7 from caking when the temperature is low. When the heating pipes 20 are heated, multiple stirring rods 9 will stir the paint, so that the temperature of the paint inside the storage box 7 can be kept consistent, which better improves the oxidation resistance of the paint. A first driven wheel 15 is installed on the outside of the annular box 6, and a driving wheel 16 engaged with the first driven wheel 15 is installed on the top of the support platform 3. One end of the rotating rod 8 extends to the top of the support platform 3 and is installed with a second driven wheel 17 engaged with the first driven wheel 15. A rotating motor for driving the driving wheel 16 to rotate is installed at the bottom of the support platform 3. A high-pressure pump 18 is installed on the top of the base plate 1. The inlet of the high-pressure pump 18 is connected to the storage box 7 through the liquid inlet pipe, and the outlet of the high-pressure pump 18 is connected to the cavity 11 through the liquid outlet pipe.

[0021] It should be noted that the gas nitriding furnace anti-oxidation structure is placed on the top of the processing table 5 when the gas nitriding furnace to be sprayed is used. When spraying, the rotating motor drives the driving wheel 16 to rotate. Under the meshing of the driving wheel 16 and the first driven wheel 15, the annular box 6 is driven to rotate. Under the drive of the annular box 6, the connecting pipe 21 is rotated. Under the drive of the connecting pipe 21, the spraying pipe 13 drives multiple nozzles 14 to rotate around the gas nitriding furnace, thereby performing multi-angle spraying on the gas nitriding furnace. Spraying, when the annular box 6 rotates, under the engagement of the first driven wheel 15 and the second driven wheel 17, the rotating rod 8 will drive the multiple stirring rods 9 to rotate, thereby stirring the paint inside the storage box 7, thereby preventing the paint from settling. During spraying, the high-pressure pump 18 will draw the paint from the storage box 7 into the cavity 11. The paint entering the cavity 11 will enter the annular box 6 through multiple feed holes 12, and then enter the spray pipe 13 through the connecting pipe 21, and finally be sprayed out by multiple nozzles 14.
