[0002] Ferrous sulfide is an inorganic compound with the chemical formula FeS. It appears as dark brown hexagonal crystals and is insoluble in water. It can be obtained by melting sulfur and iron together in a high-vacuum quartz tube. The reaction equation is Fe + S → FeS (heating is required). Due to the need to improve the stability, corrosion resistance, environmental impact, and application requirements of ferrous sulfide, it needs to be passivated.

[0003] In the related art, the two most common methods for passivation of ferrous sulfide are immersion passivation and spray passivation.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a ferrous sulfide passivation device. Figure 1-4 , a ferrous sulfide passivation device, comprising:

[0033] A passivation box 1 and a movable door 2 hinged on one side thereof;

[0034] The spray mechanism 3 is arranged inside the passivation box 1 and includes a sieve plate 31 fixedly mounted on the bottom of the inner cavity of the passivation box 1, a placement frame 32 is provided on the top of the sieve plate 31, and a spray assembly 33 is installed on the top of the inner cavity of the passivation box 1 for spraying and passivating the ferrous sulfide. A linkage assembly 34 is installed between the sieve plate 31 and the placement frame 32 for improving the passivation uniformity of the ferrous sulfide; and

[0035] The recycling mechanism 4 is provided on one side of the passivation box 1 for recycling the passivation liquid and the passivating agent.

[0036] Reference Figure 1 as well as Figure 2 The spray assembly 33 includes a box body 331 fixedly mounted on the top of the inner cavity of the passivation box 1, a T-shaped tube 337 passes through the bottom of the inner cavity of the box body 331, and one end of the T-shaped tube 337 located outside the box body 331 is connected to the spray head 332. A motor 333 is installed on one side of the top of the inner cavity of the passivation box 1, and pulleys 334 are installed on the output end of the motor 333 and the surface of the T-shaped tube 337. A transmission belt 335 is wound around the surface of the two pulleys 334, and the two pulleys 334 are connected by the transmission belt 335.

[0037] In this embodiment, the connection between the T-shaped tube 337 and the nozzle 332 is used to spray the vulcanizing agent onto the surface of the ferrous sulfide inside the placement frame 32 to passivate the ferrous sulfide. At the same time, the motor 333 drives the pulley 334 to rotate, and then drives the nozzle 332 to rotate through the transmission connection between the pulley 334 and the transmission belt 335.

[0038] Please continue to refer to Figure 2 The top of the box body 331 is connected with a connecting pipe 336. The end of the connecting pipe 336 away from the box body 331 passes through the passivation box 1 and is connected with the external liquid supply pipe to provide vulcanizing agent to the nozzle 332.

[0039] Please refer to Figure 3 as well as Figure 4 The linkage assembly 34 includes a fixing ring 341 fixedly mounted on the bottom of the placement frame 32, a tooth 342 is fixedly mounted on the bottom of the inner wall of the fixing ring 341, a linkage gear 343 is rotatably mounted on one side of the top of the sieve plate 31, and the linkage gear 343 and the tooth 342 are meshed together. A fixing rod 344 is fixedly mounted on the bottom of the nozzle 332, and the bottom end of the fixing rod 344 passes through the placement frame 32 and extends to the inside of the fixing ring 341. An asymmetric gear 345 is fixedly mounted on the bottom end of the fixing rod 344, and the asymmetric gear 345 and the linkage gear 343 are meshed together.

[0040] In this embodiment, while the nozzle 332 rotates, the fixed rod 344 and the asymmetric gear 345 at its bottom end are synchronously driven to rotate, and then the fixed ring 341 is intermittently rotated by utilizing the meshing connection of the asymmetric gear 345, the linkage gear 343 and the teeth 342, thereby driving the ferrous sulfide in the placement frame 32 to perform intermittent movement, so as to further improve the passivation uniformity of the vulcanizing agent.

[0041] Please continue to refer to Figure 3 , an annular slide rail 35 is fixedly installed on the top of the sieve plate 31, and sliders 36 are fixedly installed around the bottom of the placement frame 32, and the annular slide rail 35 and the sliders 36 are slidably connected;

[0042] In this embodiment, the placement frame 32 can maintain its stability when it rotates, so as to avoid shaking of the ferrous sulfide in the placement frame 32 and affecting the passivation uniformity.

[0043] Reference Figure 1 The recycling mechanism 4 includes a water tank 41 fixedly mounted on the bottom of the inner cavity of the passivation tank 1, a gear pump 42 is installed at the bottom of one side of the passivation tank 1, the liquid inlet end of the gear pump 42 passes through the passivation tank 1 and is connected to the water tank 41, and the liquid outlet end of the gear pump 42 is connected to a return pipe 43, and the end of the return pipe 43 away from the gear pump 42 passes through the passivation tank 1 and is connected to one side of the top of the box body 331;

[0044] In this embodiment, when the vulcanizing agent is sprayed to a certain amount through the nozzle 332, the connection between the connecting pipe 336 and the box 331 is cut off, and the gear pump 42 is simultaneously turned on to work to extract the passivating agent inside the water tank 41, and the passivating agent is injected into the interior of the box 331 by utilizing the connection between the return pipe 43 and the box 331.

[0045] The implementation principle of the ferrous sulfide passivation device of the present embodiment is as follows: an external vulcanizing agent is injected into the interior of the box 331 through the connecting pipe 336, and the sulfiding agent is sprayed onto the surface of the ferrous sulfide inside the placement frame 32 through the connection between the T-shaped pipe 337 and the spray head 332 to passivate the ferrous sulfide. At the same time, the motor 333 drives the pulley 334 to rotate, and the transmission connection between the pulley 334 and the transmission belt 335 drives the spray head 332 to rotate to increase the spray area of ​​the vulcanizing agent.

[0046] As the nozzle 332 rotates, the fixed rod 344 and the asymmetric gear 345 at its bottom are synchronously driven to rotate. The meshing connection between the asymmetric gear 345, the linkage gear 343, and the teeth 342 then causes the fixed ring 341 to intermittently rotate, thereby driving the ferrous sulfide in the placement frame 32 to intermittently move, thereby further improving the passivation uniformity of the vulcanizing agent.

[0047] When the vulcanizing agent is sprayed to a certain amount through the nozzle 332, the connection between the connecting pipe 336 and the box 331 is cut off, and the gear pump 42 is opened synchronously to extract the passivating agent inside the water tank 41, and the passivating agent is injected into the inside of the box 331 through the connection between the return pipe 43 and the box 331, thereby realizing the reuse of the passivating agent.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
