Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanized workpiece processing, in particular to a drying device for hot-dip galvanized workpiece processing. Background Technique

[0002] Hot-dip galvanized workpieces are metal products that have undergone special treatment, with a zinc layer attached to their surfaces to enhance their anti-corrosion ability. Hot-dip galvanizing, also known as hot-dip galvanization, is an effective metal anti-corrosion process. In this process, zinc ingots are melted at high temperatures and some auxiliary materials are added, and then metal structural parts are immersed in a galvanizing tank so that a zinc layer adheres to the metal components. This process usually includes multiple links such as workpiece degreasing, water washing, pickling, water washing, dipping in a fluxing agent, drying and preheating, hot-dip galvanizing, finishing, cooling, passivation, rinsing, drying, and inspection.

[0027] As shown in Figures 1 to 4 the figure, a drying device for processing hot-dip galvanized workpieces provided by the present invention includes a drying body 1;

[0028] a conveying component 2 drivingly connected inside the drying body 1;

[0029] The surface of the drying body 1 is connected with a guiding structure 4 through a transmission structure 3. The guiding structure 4 can guide and discharge the humid gas inside the drying body 1. The guiding structure 4 includes brackets 5 fixedly connected to both sides of the conveying component 2. The inner sides of the brackets 5 are fixedly connected with connecting frames 6. A connecting block 7 is arranged inside the connecting frames 6.

The surface of the impeller 8 is fixedly connected with a second helical gear 12 located on the other side of the connecting block 7. The first helical gear 11 and the second helical gear 12 are meshed with each other.

[0031] As a technical optimization scheme of the present invention, by utilizing the mutual cooperation of the reciprocating screw 9, the first helical gear 11 and the second helical gear 12, the rotation of the impeller 8 is realized. This transmission method has a compact structure, high transmission efficiency, and through the sliding connection of the first helical gear 11 in the groove 10 of the reciprocating screw 9, the stability and reliability of the transmission are ensured.

[0032] Referring to Figure 4 the figure, a sleeve block 13 is fixedly connected to the surface of the connecting block 7. One side of the sleeve block 13 away from the connecting block 7 penetrates through the connecting frame 6 and is sleeved on the surface of the reciprocating screw 9. The sleeve block 13 is threadedly connected with the reciprocating screw 9. The first helical gear 11 is movably connected with the sleeve block 13 through a bearing.

[0033] As a technical optimization solution of the present utility model, through the threaded connection between the sleeve block 13 and the reciprocating screw 9, and the movable connection between the first bevel gear 11 and the sleeve block 13, not only the structural stability is enhanced, but also the first bevel gear 11 can move along with the rotation of the reciprocating screw 9, thereby driving the rotation of the second bevel gear 12 and the impeller 8, which can simplify the transmission structure 3 and improve the transmission efficiency.

[0034] Reference Figure 3 , a pulley 14 is fixedly connected to both the transmission end of the conveying component 2 and the front end of the reciprocating screw 9, and a belt 15 is sleeved on the surface of the pulley 14.

[0035] As a technical optimization solution of the present utility model, by setting the pulley 14 and the belt 15, the linkage between the conveying component 2 and the reciprocating screw 9 is realized. When the conveying component 2 is conveying hot-dip galvanized workpieces, it can also drive the reciprocating screw 9 and the impeller 8 to rotate, realizing the continuous guiding and discharging of humid gas.

[0036] Reference Figure 2 , the conveying component 2 includes a vertical plate 16 fixedly connected to the surface of the drying machine body 1. A conveying roller 17 is movably connected to the inner side of the vertical plate 16 through a bearing.

The pulley 14 is fixedly connected to the front end of the conveying roller 17, and the bracket 5 is fixedly connected to the outside of the vertical plate 16.

[0037] As a technical optimization solution of the present utility model, by setting the conveying roller 17 and the driving motor 18, the stable conveying of the workpiece is ensured.

[0040] Working principle and usage process of the utility model: During use, the transmission motor 18 drives the conveying roller 17 to rotate. The conveying roller 17 transports the material into the drying body 1 by means of rolling force for heating and drying treatment. During the rotation of the conveying roller 17, the conveying roller 17 transmits the torque to the reciprocating screw 9 through the belt pulley 14 and the belt 15. The reciprocating screw 9 uses the thread to push the sleeve block 13 to move horizontally back and forth. During the movement of the sleeve block 13, the connecting block 7 drives the impeller 8 to move synchronously. During the continuous rotation of the reciprocating screw 9, the reciprocating screw 9 drives the first bevel gear 11 to rotate by means of the inlay relationship between the surface groove 10 and the first bevel gear 11. The first bevel gear 11 drives the impeller 8 to rotate and guides the external air flow through the second bevel gear 12, so that the air flow enters the drying body 1 for replenishment and replaces the humid air flow inside the drying body 1, reducing the content of humid gas entering the cycle.

[0041] In summary: For the drying device for hot-dip galvanized workpieces, by arranging the guiding structure 4 connected to the transmission structure 3 on the surface of the drying body 1, the effective guiding and discharging of the humid gas inside the drying body 1 are realized, the drying efficiency is improved, the accumulation of humid gas in the drying body 1 is avoided, and the possibility of affecting the drying effect due to excessive humidity is reduced.
