DETAILED DESCRIPTION

[0020] In order to make the skilled person in the art more clear and explicit about the technical scheme of the utility model, the utility model will be further described in detail below in combination with the embodiments and the drawings, but the implementation manner of the utility model is not limited to this.

[0021] As Figures 1-3As shown, this embodiment provides a valve surface passivation treatment device, including a treatment box 1, a base plate 2 installed at the bottom of the treatment box 1, a stirring mechanism 3 provided between the base plate 2 and the treatment box 1, a guiding mechanism 4 installed on both sides of the treatment box 1, a carrying net 5 provided inside the treatment box 1, the carrying net 5 is used to carry the valve, a treatment mechanism 6 is connected to the carrying net 5, the treatment mechanism 6 includes a winch 601 and a cable 602, the winch 601 is connected to the carrying net 5 through the cable 602, so that the winch 601 can drive the carrying net 5 to rise and fall and tilt it through the cable 602, and a drying mechanism 7 is provided around the inside of the treatment box 1.

[0022] like Figures 1-2 As shown, the drying mechanism 7 includes an air tank 701, an external interface 702, and a nozzle 703. The air tank 701 is fixedly connected to the processing box 1, which facilitates the drying of the valve through the drying mechanism 7.

[0023] like Figures 1-2 As shown, the nozzle 703 is threadedly connected to the air groove 701, and the nozzle 703 has an inclined structure, which allows the dry gas guided by the air groove 701 to be blown towards the valve through the nozzle 703.

[0024] like Figures 1-2 As shown, the external interface 702 is connected to the air tank 701 via a clamp, and the external interface 702 penetrates the side wall of the processing box 1, making it convenient for the external air supply pipeline to be connected to the air tank 701 through the external interface 702.

[0025] like Figure 2 As shown, the stirring mechanism 3 includes a motor 301 fixed at the bottom of the processing tank 1. A connecting shaft 302 is installed at the output end of the motor 301, which enables the motor 301 to drive the connecting shaft 302 to rotate.

[0026] like Figure 2 As shown, the connecting shaft 302 passes through the base plate 2, and a stirring rack 303 is fixed at the top of the connecting shaft 302, so that the connecting shaft 302 can drive the stirring rack 303 to rotate.

[0027] like Figures 1-3 As shown, the guiding mechanism 4 includes a guide wheel 401, a support shaft 402, and a support frame 403. The guide wheel 401 is rotatably connected to the support shaft 402, and the support shaft 402 is fixed on the support frame 403. During use, the cable 602 can contact the guide wheel 401. At this time, the guide wheel 401 rotates along the support shaft 402 on the support frame 403 due to friction, and the cable 602 is guided by the guide wheel 401.

[0028] The working principle of this device is as follows: In actual use, the processing mechanism 6 positions the carrying net 5 above the processing box 1. The operator places multiple valves on the carrying net 5. After placement, the winch 601 inside the processing mechanism 6 uses a cable 602 to move the carrying net 5 and the valves into the passivation liquid in the processing box 1 for passivation treatment. During the movement, the cable 602 contacts the guide wheel 401. At this time, the guide wheel 401 rotates along the support shaft 402 on the support frame 403 due to friction. The guide wheel 401 guides the cable 602. During the valve passivation process, the motor 301 drives the connecting shaft 3... 02 rotates, and the connecting shaft 302 can drive the stirring frame 303 to rotate. The stirring makes the passivation liquid flow, thereby improving the passivation efficiency. After the passivation is completed, the carrying net 5 is reset. At this time, the external interface 702 in the drying mechanism 7 is connected to the air supply pipeline. The drying gas is guided through the air groove 701 and blown from the nozzle 703 to the workpiece for drying. During the drying process, one of the winches 601 drives the carrying net 5 to tilt. At this time, the valve rolls to prevent the contact position with the carrying net 5 from not being dried, thereby improving the drying efficiency, preventing the passivation liquid from spilling around the device, and improving the cleanliness of the surrounding environment.
