[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle the steel parts to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.

Currently, when drying the galvanized flange, hot air can only be blown on a certain outer surface of the flange, and the outer surface of the flange cannot be dried evenly. In addition, it is inconvenient to place the flange into the drying equipment during operation, and the placement steps are relatively cumbersome, which reduces the work efficiency of the flange drying process.

[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] The present application embodiment discloses a hot dip galvanizing drying device. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, it includes a drying cylinder 1, the bottom of the inner wall of the drying cylinder 1 is fixedly connected to one end of the motor 2, the motor shaft at the other end of the motor 2 is fixedly connected to one end of the first connecting sleeve 3, the inner wall of the other end of the first connecting sleeve 3 is slidably connected to the outer surface of one end of the first connecting rod 4, the other end of the first connecting rod 4 is fixedly connected to the bottom of the fixed plate 5, the inner wall of one side in the middle of the fixed plate 5 is rotatably connected to the outer surface of one end of the positioning rod 7, one end of the positioning rod 7 is fixedly connected to one end of the second connecting rod 8, and the outer surface of the other end of the second connecting rod 8 is slidably connected to the inner wall of one end of the second connecting sleeve 9.

[0029] The outer surface of one side in the middle of the positioning rod 7 is fixedly connected to one side of one end of the connecting frame 12 through a fixing rod, one side of the inner wall in the middle of the connecting frame 12 is rotatably connected to the inner wall in the middle of the support plate 13 through a supporting rod, one side of the support plate 13 is fixedly connected to one end of the sliding frame 14, the inner wall in the middle of the sliding frame 14 is slidably connected to the outer surface in the middle of the sliding rod 15, the outer surface of one side in the middle of the sliding rod 15 is fixedly connected to one end of the push rod 16, and the other end of the push rod 16 is rotatably connected to one end of the support plate 13 through a hinged frame.

[0030] The outer surface of the middle portion of the top of the fixing plate 5 is fixedly connected to one end of the suspension rod 6 .

[0031] See also Figure 6 The cross-section of one end of the first connecting rod 4 is a quadrilateral, and the cross-section shape of one end of the first connecting rod 4 is adapted to the inner wall cavity of one end of the first connecting sleeve 3, so that the first connecting rod 4 can be taken out from the first connecting sleeve 3, and then the flange placement structure can be taken out from the inside of the drying drum 1, and when putting it back, the first connecting sleeve 3 can drive the first connecting rod 4 to rotate without too many installation steps.

[0032] See also Figure 3 The top cross-section of the second connecting rod 8 is a quadrilateral, and the bottom end of the second connecting rod 8 is a four-sided cone. The shape of the outer surface of the middle part of the second connecting rod 8 is adapted to the shape of the inner wall cavity of one end of the second connecting sleeve 9. The four-sided cone at the bottom end of the second connecting rod 8 allows the second connecting rod 8 to be inserted into the second connecting sleeve 9 more smoothly. There is no need to adjust the angle of the second connecting rod 8 before insertion. It is only necessary to align the first connecting rod 4 with the first connecting sleeve 3.

[0033] See also Figure 6 The bottom of the second connecting sleeve 9 is fixedly connected to the top of the gear 10, and the bottom of the gear 10 is rotatably connected to the outer surface of one side of the middle part of the first connecting sleeve 3 through a support frame. The rotation of the gear 10 can make the second connecting sleeve 9 cooperate with the second connecting rod 8 to drive the positioning rod 7 to rotate, so that the positioning rod 7 drives the flange to rotate through the support plate 13.

[0034] See also Figure 2 The teeth on the outer surface of the middle part of the gear 10 mesh with the teeth on the inner wall of the middle part of the gear ring 11. One side of the outer surface of the middle part of the gear ring 11 is fixedly connected to one side of the inner wall of the middle part of the drying cylinder 1 through a fixing rod. When the first connecting sleeve 3 drives the gear 10 to rotate around the motor 2, the gear 10 will rotate through the gear ring 11.

[0035] See also Figure 6A sliding frame 14, a sliding rod 15, and a push rod 16 are provided between each two adjacent upper and lower support plates 13. The sliding frame 14 is cancelled on one side of the support plate 13 located at the top, and the push rod 16 is cancelled on the support plate 13 located at the bottom. The sliding frame 14, the sliding rod 15, and the push rod 16 cooperate with each other between the upper and lower adjacent support plates 13. When the flange falls on the support plate 13 located below in a ready-to-receive state, the support plate 13 located below will swing, driving the sliding frame 14 to move upward, so that the sliding frame 14 drives the upper support plate 13 to swing through the cooperation of the sliding rod 15 and the push rod 16, so that the upper support plate 13 swings to an angle ready to receive.

[0036] See also Figure 4 A first limiting rod 17 and a second limiting rod 18 are fixedly provided on one side of the inner wall in the middle of the connecting frame 12. The first limiting rod 17 is positioned below each support plate 13, and the second limiting rod 18 is positioned above the support plate 13 at the bottom. The first limiting rod 17 can support the support plate 13 after the flange has been placed, and the second limiting rod 18 can limit the support plate 13 at the bottom, so that the support plate 13 at the bottom can be easily adjusted to an angle ready for receiving.

[0037] The implementation principle of a hot-dip galvanizing drying equipment in the embodiment of the present application is as follows: the external lifting device is hung in the lifting ear at the top of the hanging rod 6, and the hanging rod 6 and the fixed plate 5 are lifted upward to the outside of the drying cylinder 1. Then the worker puts the flange that needs to be dried after cleaning on the positioning rod 7, and gradually slides the flange downward. When the flange slides to the top of one end of the support plate 13 at the bottom that is ready to receive, the flange will drive it to swing to a horizontal state. At the same time, when the support plate 13 swings, the sliding frame 14 fixedly connected to it will move upward, so that the sliding frame 14 drives the support plate 13 above the support plate 13 to swing through the cooperation of the sliding rod 15 and the pushing rod 16, so that it swings to a ready to receive state, and then the flanges are put on the positioning rod 7 one by one. After a certain number of flanges are placed, the fixed plate 5 is lifted back to the inside of the drying cylinder 1 by the hanging rod 6, and the first connecting rod 4 and the first connecting sleeve 3 are put downward, so that the first connecting rod 4 is inserted into the first connecting sleeve 3, and the first connecting rod 4 continues to move downward. During the process, the second The quadrilateral conical outer surface at the bottom of the connecting rod 8 will be inserted into the inner wall of one end of the second connecting sleeve 9. When the second connecting rod 8 is inserted for a certain distance, the second connecting sleeve 9 cooperates with the quadrilateral conical outer surface at the bottom of the second connecting rod 8 to drive the second connecting rod 8 to rotate, so that the upper side of the second connecting rod 8 rotates to match the angle of the inner wall insertion port at one end of the second connecting sleeve 9, until the second connecting rod 8 is fully inserted into place, the air outlet on one side of the inner wall of the drying cylinder 1 starts to work, and the flange inside the drying cylinder 1 is blown. The motor 2 works to drive the first connecting sleeve 3 to rotate, so that the first connecting rod 4 drives the fixing plate 5 to rotate, and the flange starts to rotate around the motor 2. When the first connecting sleeve 3 rotates, it can drive the gear 10 to rotate around the motor 2, and then the gear 10 can drive the second connecting sleeve 9 to rotate through the gear ring 11, so that the second connecting rod 8 drives the positioning rod 7 to rotate, and then the flange is driven to rotate through the connecting frame 12 and the support plate 13 to adjust the position angle of the flange facing the air outlet inside the drying cylinder 1.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
