[0020] Please refer toFigures 1-6 , the present utility model provides the following technical solutions: a pre-treatment device for hot dip galvanizing of high-strength steel structure large hexagon bolts without pickling, including a box body 1, a liquid storage tank 2 and an electric spool 5, further including a suction fan 3 and a mesh box 4. Both sides of the box body 1 are provided with a liquid storage tank 2 communicated therewith. The top of the box body 1 is provided with a slide rail 11, and the top of the slide rail 11 is provided with an electric spool 5. A connecting wire 51 is wound around the electric spool 5. Fixed blocks 52 are fixed on several branch wires of the connecting wire 51. Several moving grooves 53 are provided on the top of the mesh box 4. Threaded grooves 54 are provided on the moving grooves 53 and the fixed blocks 52 and are matched with each other. Screws are installed on the threaded grooves 54 on the fixed blocks 52 and the moving grooves 53 that are matched with each other. Several mounting frames 41 are slidably installed inside the mesh box 4, and mesh plates 42 are installed on the mounting frames 41. A suction fan 3 and a hot air fan 31 communicated with each other are provided on the outer wall of the box body 1. The suction fan 3 and the hot air fan 31 are communicated with an exhaust air plate 34 through a telescopic air pipe 33. The bottom of the exhaust air plate 34 is provided with protrusions on both sides inside the box body 1. Several exhaust grooves are provided on the opposite side walls of the protrusions at the bottom of the exhaust air plate 34.

[0021] The liquid storage tank 2 is used to store cleaning liquid and water. The box body 1 is used for pre-treating large hexagon bolts. The liquid storage tank 2 can send the liquid stored inside to the inside of the box body 1. By sequentially sending the cleaning liquid and water into the box body 1, the cleaning of debris on the large hexagon bolts and the cleaning liquid adhering to the large hexagon bolts is realized. A pipeline communicating with the liquid storage tank 2 is provided at the bottom of the box body 1. Through the bottom pipeline, the liquid inside the box body 1 can be sent back to the liquid storage tank 2, realizing the reuse of the cleaning liquid and water. The hot air blower 31 can generate hot air flow. The exhaust air plate 34 can transport the hot air flow generated by the hot air blower 31 to the inside of the box body 1 through the exhaust slots provided on the bottom protrusions. Through the cooperation of the exhaust fan 3 and the exhaust slots provided on the other bottom protrusion of the exhaust air plate 34, the air inside the box body 1 can be evacuated from the box body 1. Subsequently, the exhaust fan 3 will transport the air evacuated from the box body 1 to the hot air blower 31, thus realizing the reuse of the hot air flow. The circulating air flow improves the drying effect of the hot air blower 31 and the exhaust fan 3 on the large hexagon bolts. The position where the bottom protrusions of the exhaust air plate 34 are provided ensures that the hot air flow entering the box body 1 will be evacuated from the box body 1 by the exhaust fan 3 after passing through the mesh box 4, ensuring the working effect of the hot air flow. The telescopic air pipe 33 is of an extendable structure, enabling the user to move the bottom protrusions of the exhaust air plate 34 out of the box body 1, facilitating the user to replace the exhaust air plate 34. The mesh box 4 is used to place the large hexagon bolts to be cleaned. The mesh plate 42 is used to place the large hexagon bolts, ensuring that the large hexagon bolts will not stack together during the use of the device, ensuring the cleaning effect of the cleaning liquid and water. At the same time, the large hexagon bolts placed on the mesh plate 42 also ensure the drying effect of the exhaust fan 3 and the hot air blower 31 on the large hexagon bolts. The structure of the mesh plate 42 ensures that the liquid and air flow can fully contact the large hexagon bolts, ensuring the cleaning and drying effects of the device on the large hexagon bolts. The mounting frame 41 is slidably mounted on the mesh box 4. By adjusting the position of the mounting frame 41 mounted on the mesh box 4, the distance between the mesh plates 42 can be adjusted, enabling the device to be applicable to large hexagon bolts of different sizes. The mesh box 4 is connected to the connecting line 51 through the fixing block 52 mounted on the moving groove 53. When the electric wire spool 5 is started, the connecting line 51 drives the mesh box 4 to move under the drive of the electric wire spool 5, thus realizing the adjustment of the position of the mesh box 4, facilitating the user to place and take out the large hexagon bolts. Several threaded grooves 54 matching the threaded grooves 54 provided on the fixing block 52 are provided on the moving groove 53, facilitating the user to adjust the position where the fixing block 52 is fixed on the moving groove 53, thus realizing the adjustment of the force-bearing position of the mesh box 4 and facilitating the user to control the lifting of the mesh box 4.

[0022] Specifically, the mesh plate 42 is hinged to the mounting frame 41. Pin frames 43 are provided at the top and bottom of the mesh plate 42. Fixed pins 44 matching the pin frames 43 are provided on the side wall of the mounting frame 41. Grooves matching the fixed pins 44 are provided on the side wall of the mesh plate 42.

[0023] When the device is in use, the wire mesh plate 42 is fixed through the cooperation of the fixing pin 44 and the grooves and pin frames 43 that cooperate with it, ensuring the stability of the wire mesh plate 42 during the use of the device. When the fixing pin 44 cooperates with the side wall groove of the wire mesh plate 42, the wire mesh plate 42 is in a horizontal state, ensuring the stability of the bolt during the use of the device. When the fixing pin 44 cooperates with the pin frame 43 located above the wire mesh plate 42, the wire mesh plate 42 inclines towards the opening of the wire cage 4, facilitating the user to take out the bolts placed on the wire mesh plate 42 from the wire cage 4. When the fixing pin 44 cooperates with the pin frame 43 located below, the wire mesh plate 42 inclines towards the inside of the wire cage 4, facilitating the user to place the bolts into the inside of the wire cage 4.

[0024] Specifically, two through grooves are provided on the side wall of the fixing pin 44 that cooperates with the pin frame 43, and the mounting frame 41 is provided with a fixing pin 44 that cooperates with the through grooves on the side wall of the fixing pin 44.

[0025] Through the cooperation of the fixing pin 44 and the through grooves provided on the fixing pin 44 that cooperates with the pin frame 43, the fixing pin 44 can be fixed, thereby ensuring the stability of the wire mesh plate 42 during the use of the device. The distance between the two through grooves provided on the fixing pin 44 ensures that the fixing pin 44 can remain in a state separated from the side wall groove of the wire mesh plate 42 and the pin frame 43 and a state of cooperation between the fixing pin 44 and the side wall groove of the wire mesh plate 42 and the pin frame 43. The fixing pin 44 that cooperates with the fixing pin 44 is located above the fixing pin 44 that cooperates with the pin frame 43, ensuring the stability of the cooperation between the fixing pin 44 and the through grooves on the side walls of the pin frame 43 and the wire mesh plate 42, and further enhancing the stability of the wire mesh plate 42 during the use of the device.

[0026] Specifically, the positions of the pin frames 43 located on the same side are staggered.

[0027] The positions of the two pin frames 43 located on the same side are arranged such that the pin frames 43 provided on the opposite side walls of the adjacent wire mesh plates 42 are in an overlapping state. While ensuring that the installation of the adjacent wire mesh plates 42 is not hindered, the length of the pin frame 43 is increased. Furthermore, when the pin frame 43 and the fixing pin 44 cooperate, the inclination angle of the wire mesh plate 42 is increased, ensuring the working effect of the inclined wire mesh plate 42.

[0028] Specifically, protrusions are provided on the side wall of the bottom protrusion of the exhaust air plate 34, and the width of the protrusions on the side wall of the bottom protrusion of the exhaust air plate 34 is the same as the distance between the wire cage 4 and the bottom protrusion of the exhaust air plate 34.

[0029] When the net box 4 and the exhaust air plate 34 are moved into the interior of the box body 1, the side wall protrusion of the exhaust air plate 34 can seal the space between the exhaust air plate 34 and the net box 4. At this time, the interior space of the box body 1 is in a closed state, ensuring that the exhaust fan 3 can completely extract the hot air sent into the interior of the box body 1 by the hot air blower 31 from the box body 1, reducing the heat waste caused by the hot air generated by the hot air blower 31 during the use of the device.

[0030] Specifically, a filter box 32 is provided on the pipeline connecting the exhaust fan 3 and the hot air blower 31.

[0031] The filter box 32 can dry and filter the air extracted from the box body 1 by the exhaust fan 3, preventing the air flow sent into the interior of the box body 1 by the hot air blower 31 from containing moisture when the device recycles hot air, which may affect the drying effect of the bolts by the device and thus the pretreatment efficiency of the bolts by the device.

[0032] Specifically, a connecting block 12 is slidably mounted on the slide rail 11, and the connecting block 12 is fixed to the top of the net box 4.

[0033] The connecting block 12 is slidably mounted on the groove of the slide rail 11. There are grooves on the side wall of the groove of the slide rail 11, and protrusions are provided on the side wall of the connecting block 12 that cooperate with the grooves on the side wall of the groove of the slide rail 11. The cooperation between the side wall protrusion of the connecting block 12 and the cooperating groove plays a limiting role, ensuring the stability of the connecting block 12 during the sliding process on the slide rail 11. The connecting block 12 is fixed to the net box 4, and the cooperation between the connecting block 12 and the slide rail 11 ensures the stability of the net box 4 during the lifting and lowering process.

[0034] Working principle and usage process of the present utility model: Control the electric spool 5 to wind up the connecting line 51. The net cage 4 rises under the drive of the connecting line 51, the sealing door of the net cage 4 is opened, the cooperation between the fixing pin 44 and the side wall groove of the net plate 42 is released, the net plate 42 is rotated upward, and the net plate 42 is fixed in a state inclined towards the inside of the net cage 4 through the cooperation between the fixing pin 44 and the pin frame 43 arranged at the bottom of the net plate 42. Place the bolts on the net plate 42, then move the net plate 42 to the horizontal state, seal the sealing door of the net cage 4, control the electric spool 5 to release the connecting line 51, and the net cage 4 moves back to its original position. Send the cleaning liquid in the liquid storage tank 2 into the inside of the box body 1. After the sundries attached to the bolts are cleaned up, pump the cleaning liquid back into the inside of the liquid storage tank 2. Then send the water in the liquid storage tank 2 into the inside of the box body 1. After the cleaning liquid on the bolts is rinsed clean, send the water back into the inside of the liquid storage tank 2. Start the exhaust fan 3 and the hot air blower 31. The hot air blower 31 sends hot air into the inside of the box body 1 through the exhaust air plate 34. The hot air flow will dry the moisture on the bolts. The hot air flow in the box body 1 will be drawn out of the box body 1 by the exhaust fan 3. Then the hot air flow is dried and filtered by the filter box 32 and sent back into the box body 1 by the hot air blower 31 again. After the drying of the bolts is completed, turn off the exhaust fan 3 and the hot air blower 31, move the net cage 4 out of the box body 1, open the sealing door of the net cage 4, rotate the net plate 42 to a state inclined towards the outside of the net cage 4, and the bolts arranged on the net plate 42 are discharged from the net cage 4.
