Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing, in particular to a bolt drying device before galvanizing. Background Art

[0002] Hot-dip galvanizing is to immerse the rust-removed metal parts into zinc liquid for adhesion, so as to achieve an anti-corrosion effect. Many bolts will be hot-dip galvanized, and when galvanizing, it is usually necessary to clean the metal parts first. After cleaning, they need to be dried before hot-dip galvanizing, so a dryer is needed.

[0003] For example, the patent with application number 202221148418.3 discloses a pre-drying machine for hot-dip galvanizing, including a dryer and a bracket, the bracket is fixedly connected to the top of the dryer, a cooling fan is arranged on the top of the bracket, and a clamping block is fixedly connected to the front and rear sides of the cooling fan, and a clamping groove is provided on the left and right sides of the clamping block. The utility model is provided with a dryer, a bracket, a cooling fan, a clamping block, a clamping groove, a fixed block, a fixed groove, a positioning mechanism and an adjusting mechanism for coordinated use. The positioning mechanism is driven to enter the interior of the fixed groove by pulling the adjusting mechanism. At this time, the cooling fan can be disassembled or installed, and after completion, it is restored and the adjusting mechanism is pulled in the opposite direction. The clamping block is fixed by the use of the positioning mechanism to fix the cooling fan, thereby solving the problem that the surface temperature of the existing parts is too high after drying, which is inconvenient for subsequent hot-dip galvanizing. Therefore, the parts need to be cooled after drying, so as to facilitate the subsequent hot-dip galvanizing process.

[0004] At present, the temperature of the bolts will be relatively high after drying in the dryer used before galvanizing. At this time, galvanizing cannot be carried out. Galvanizing can only be continued after the bolts are cooled. Therefore, some dryers will add a structure to cool the bolts. For example, the dryer in the above patent adds a fan, but the cavity where the drying part of these dryers is located is directly connected to the cooling part, so the hot air from drying and the cool air from cooling are easy to mix with each other and interfere with each other, affecting the drying effect and the cooling effect. Summary of the invention

[0005] The disclosed embodiment relates to a device for drying bolts before galvanizing, which can improve the drying effect and cooling effect, and the cooled bolts can be directly discharged downwards, which is very convenient to use.

[0011] In at least some embodiments, the bolt conveying disc is provided with a total of six cylindrical holes extending vertically and arranged in a circular pattern, and the inner diameters of the six cylindrical holes are equal to the inner diameters of the bolt placement opening and the bolt discharge opening.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1: Please refer to Figures 1 to 6 :

[0029] The present embodiment proposes a device for drying bolts before galvanizing, comprising: a drying box body 1; a total of six supporting legs 2 are arranged at the bottom of the drying box body 1 by welding, the drying box body 1 is used to support the bolt conveying disc 8, and the supporting legs 2 are used to support the drying box body 1; a bolt placement opening 3 is arranged on the right side of the top of the drying box body 1, when it is necessary to dry the bolts before galvanizing, the bolts can be placed in the cylindrical holes on the bolt conveying disc 8 directly below the bolt placement opening 3 through the bolt placement opening 3, and then the stepping motor 9 is controlled to drive the bolt conveying disc 8 to rotate 60° and stop, at which time the cylindrical hole on the bolt conveying disc 8 will be located below the drying cover 5, so the hot air introduced into the drying cover 5 through the vortex tube 7 will contact the bolts in the cylindrical hole, and because the cylindrical hole will also be located above the small circular hole on the outer wall of the bottom of the drying box body 1, the hot air will flow downward and be discharged downward through the small circular hole on the outer wall of the bottom of the drying box body 1, and in this process the hot air will evenly contact the bolts to achieve a drying effect.

[0030] A bolt discharge port 4 is arranged on the right side of the bottom of the drying box body 1, and the screws cooled in the cylindrical holes on the bolt conveying disc 8 will also rotate to the top of the bolt discharge port 4, and then these cooled screws will directly fall down without the need for manual material removal; a drying cover 5 is arranged on the front side of the top of the drying box body 1 by welding, and two of the cylindrical holes on the bolt conveying disc 8 will be located below the drying cover 5 when the bolt conveying disc 8 is stationary, so the hot air introduced into the drying cover 5 through the vortex tube 7 will contact the bolts in the two cylindrical holes, and because the two cylindrical holes will also be located above the small circular holes on the outer wall of the bottom of the drying box body 1, the hot air will flow downward and pass The hot air will be discharged downward through the small circular holes on the bottom outer wall of the drying box body 1. In this process, the hot air will be in uniform contact with the bolts to achieve a drying effect. A cooling hood 6 is provided on the top rear side of the drying box body 1 by welding. When the bolt conveying disc 8 is stationary, two of the cylindrical holes on the bolt conveying disc 8 will be located below the cooling hood 6. Therefore, the cold air introduced into the cooling hood 6 through the vortex tube 7 will be in contact with the bolts in the two cylindrical holes. Because the two cylindrical holes will also be located above the small circular holes on the bottom outer wall of the drying box body 1, the cold air will flow downward and be discharged downward through the small circular holes on the bottom outer wall of the drying box body 1. In this process, the cold air will be in uniform contact with the bolts to achieve a cooling effect.

[0031] A vortex tube 7 is also provided in the middle position of the top of the drying box body 1, and the front and rear ends of the vortex tube 7 are respectively connected with the cavities inside the drying cover 5 and the cooling cover 6. After the vortex tube 7 introduces compressed air, it can respectively discharge hot air and cold air through the openings at the front and rear ends thereof, so that the bolts can be dried and cooled; a bolt conveying disc 8 is rotatably installed inside the drying box body 1, and the bolt conveying disc 8 is used to hold the bolts; a stepper motor 9 is installed in the middle position of the bottom of the drying box body 1 through a bracket, and the top end of the main shaft of the stepper motor 9 is fixedly connected to the middle position of the bottom of the bolt conveying disc 8, and the stepper motor 9 is used to drive the bolt conveying disc 8 to rotate.

[0032] In the present disclosure, Figure 1 and Figure 2 As shown, when the bolt conveying disc 8 is in a stationary state, one of the cylindrical holes on the bolt conveying disc 8 will be located directly below the bolt placement port 3, and another cylindrical hole will be located directly above the bolt discharge port 4. When it is necessary to dry the bolts before galvanizing, the bolts can be placed through the bolt placement port 3 in the cylindrical holes on the bolt conveying disc 8 directly below the bolt placement port 3, and each time the bolt conveying disc 8 rotates, there will be a cylindrical hole directly below the bolt placement port 3, so the bolts can be placed continuously, and the cooled screws in the cylindrical holes on the bolt conveying disc 8 will also rotate to directly above the bolt discharge port 4, and at this time these cooled screws will fall directly downwards, without the need to manually take out the material, and only need to continuously discharge the material.

[0033] In the present disclosure, Figure 3-Figure 6 As shown, a cylindrical cavity corresponding to the size of the bolt conveying disc 8 is provided inside the drying box 1, and the outer wall of the bolt conveying disc 8 is in close contact with the inner wall of the drying box 1, thereby ensuring the stability of the bolt conveying disc 8 during rotation.

[0034] In the present disclosure, Figure 4 As shown, the cavities inside the drying hood 5 and the cooling hood 6 are connected to the cavities inside the drying box 1, and when the bolt conveying disc 8 is in a stationary state, the two cylindrical holes on the left front of the bolt conveying disc 8 will be located directly below the drying hood 5, and the two cylindrical holes on the left rear of the bolt conveying disc 8 will be located directly below the cooling hood 6. Therefore, the hot air and cold air exported through the vortex tube 7 can dry and cool the bolts in the two cylindrical holes on the left front of the bolt conveying disc 8 and the two cylindrical holes on the left rear of the bolt conveying disc 8.

[0035] In the present disclosure, Figure 1-Figure 5As shown, the bolt conveying disc 8 is provided with a total of six cylindrical holes which are arranged in a ring and pass through from top to bottom, and the inner diameters of the six cylindrical holes are equal to the inner diameters of the bolt placement port 3 and the bolt discharge port 4. When the bolts are dried, the cylindrical holes on the bolt conveying disc 8 can hold the bolts, and the bolts can also be transferred when the bolt conveying disc 8 rotates.

[0036] In the present disclosure, Figure 1-Figure 5 As shown, each time the stepper motor 9 drives the bolt conveying disc 8 to rotate, it will rotate 60°, and the direction of rotation of the stepper motor 9 driving the bolt conveying disc 8 is clockwise. Therefore, each time the stepper motor 9 drives the bolt conveying disc 8 to rotate, one of the cylindrical holes can be located directly below the bolt placement port 3, and another cylindrical hole is located directly above the bolt discharge port 4, which is convenient for placing the bolts and allowing the cooled bolts to fall downwards, and can also drive the bolts to be dried first and then cooled.

[0037] In the present disclosure, Figure 2 and Figure 5 As shown, four groups of small circular holes penetrating from top to bottom are arranged on the bottom outer wall of the drying box body 1, and when the bolt conveying disc 8 is in a stationary state, four of the cylindrical holes on the bolt conveying disc 8 will be located directly above the four groups of small circular holes. Therefore, the hot air in the drying cover 5 will flow downward and be discharged downward through the small circular holes on the bottom outer wall of the drying box body 1. In this process, the hot air will be in uniform contact with the bolts to achieve a drying effect, and the cold air in the cooling cover 6 will flow downward and be discharged downward through the small circular holes on the bottom outer wall of the drying box body 1. In this process, the cold air will be in uniform contact with the bolts to achieve a cooling effect.

[0038] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the outer wall of the bolt conveying disc 8 may also be wrapped with a layer of rubber, and the rubber on the outer wall of the bolt conveying disc 8 can be tightly attached to the inner wall of the drying box 1. Therefore, after the bolt conveying disc 8 completes its rotation, it can ensure that the cavities inside the drying cover 5 and the cooling cover 6 are isolated, so that the bolts in the two cylindrical holes on the left front of the bolt conveying disc 8 and the two cylindrical holes on the left rear of the bolt conveying disc 8 can be dried and cooled independently.

[0039] The working principle of this embodiment is as follows: before use, the drying box body 1 is placed by supporting the supporting legs 2. When the bolts before galvanizing need to be dried, the bolts can be placed in the cylindrical holes on the bolt conveying disc 8 directly below the bolt placing opening 3 through the bolt placing opening 3. Then the stepper motor 9 is controlled to drive the bolt conveying disc 8 to rotate 60° and stop. At the same time, compressed air is introduced into the vortex tube 7. After the compressed air is introduced into the vortex tube 7, hot air and cold air can be respectively discharged through the openings at the front and rear ends thereof. Each time the stepper motor 9 drives the bolt conveying disc 8 to rotate, one of the cylindrical holes can be located directly below the bolt placing opening 3, thereby facilitating the continuous placement of the bolts. When the bolt conveying disc 8 is stationary, two of the cylindrical holes on the bolt conveying disc 8 will be located below the drying cover 5. Therefore, the hot air introduced into the drying cover 5 through the vortex tube 7 will contact the bolts in the two cylindrical holes, and because the two cylindrical holes will also The hot air is located above the small circular holes on the bottom outer wall of the drying box body 1, so the hot air will flow downward and be discharged downward through the small circular holes on the bottom outer wall of the drying box body 1. In this process, the hot air will evenly contact the bolts to achieve a drying effect. When the bolt conveying disc 8 is stationary, two of the cylindrical holes on the bolt conveying disc 8 will also be located below the cooling cover 6. Therefore, the cold air introduced into the cooling cover 6 through the vortex tube 7 will contact the bolts in the two cylindrical holes, and because the two cylindrical holes will also be located above the small circular holes on the bottom outer wall of the drying box body 1, the cold air will flow downward and be discharged downward through the small circular holes on the bottom outer wall of the drying box body 1. In this process, the cold air will evenly contact the bolts to achieve a cooling effect. Finally, the cooled screws in the cylindrical holes on the bolt conveying disc 8 will also rotate to just above the bolt discharge port 4. At this time, the cooled screws will fall directly downward without the need for manual material removal.
