[0027] The preferred embodiments of the utility model will be described below in combination with the drawings. It should be understood that the preferred embodiments described here are only for illustrating and understanding the utility model, and are not used to limit the utility model.

[0028] Embodiment Scattering equipment of hot galvanizing flat pad

[0029] As Figure 1As shown, including rack 1, rack 1 is composed of thick wall square tube, make rack 1 can withstand the rotation of the scattered disc 5 and the impact force of the flat pad and not produce deformation. Rack 1 is fixed with the distribution shell 2, the upper part of the distribution shell 2 is fixed with the upper hopper 3, the lower part of the distribution shell 2 is fixed with the lower cylinder 4, the distribution shell 2 is rotatably provided with the scattered disc 5, the gap is provided between the scattered disc 5 and the inner wall of the distribution shell 2, the flat pad enters the distribution shell 2 from the upper hopper 3, falls on the scattered disc 5, and the flat pad is separated by the rotation of the scattered disc 5, and the separated flat pad falls in the lower cylinder 4 through the gap between the scattered disc 5 and the distribution shell 2 and is discharged.

[0030] The distribution shell 2 is cylindrical, and the end connected with the upper hopper 3 is the feeding end, and the end connected with the lower cylinder 4 is the discharging end. The ammonia water spraying assembly is arranged on the feeding end of the distribution shell 2 and includes a spraying pipe and a spraying head 7. Two spraying warehouses 21 are arranged on the end face of the feeding end of the distribution shell 2, and the ammonia water spraying assembly is arranged on each spraying warehouse 21. The two spraying warehouses 21 are annular and concentrically arranged with the distribution shell 2. Each spraying warehouse 21 is provided with a plurality of liquid outlet holes in communication with the distribution shell 2. The annular spraying warehouse 21 can cover a larger area in the distribution shell 2, thereby improving the ammonia explosion effect. While the flat pad is scattered in the distribution shell 2, the ammonia water spraying assembly sprays ammonia water on the flat pad, so that the flat pad is always in the ammonia explosion state and is prevented from being oxidized.

[0031] As shown in Figure 2 , Figure 3 The scattered disc 5 is disc-shaped, and the circular rod 6 is fixed on the scattered disc 5. The flat pad is separated by colliding with the circular rod 6. The scattered disc 5 is provided with a distribution protrusion 8 at the center for scattering the gasket to the periphery. The distribution protrusion 8 is a cone, and the tip thereof faces the upper hopper 3. Since the centrifugal force of the center of the scattered disc 5 is small, the flat pad cannot be separated. The distribution protrusion 8 can separate the flat pad to the periphery of the scattered disc 5 and prevent the flat pad from being accumulated in the center. The scattered disc 5 rotates through a transmission device. The transmission device includes a rotating shaft 9 rotatably arranged on the rack 1 and a power device for driving the rotating shaft 9 to rotate. One end of the rotating shaft 9 penetrates the lower cylinder 4 and is detachably connected with the scattered disc 5. The other end of the rotating shaft 9 is fixed with a driven pulley. The power device is an electric motor 10. The electric motor 10 is connected with an XWY type cycloidal pin wheel speed reducer 11. A driving pulley is fixed on the output shaft of the speed reducer 11. The driving pulley and the driven pulley are sleeved with a synchronous belt. The gap between the scattered disc 5 and the inner wall of the distribution shell 2 is adjusted by replacing the scattered disc 5 with different diameters, so that the flat pad of different sizes can be processed, and the bolt or nut can also be processed.

[0032] As shown in Figure 4As shown, an outer sleeve 12 is fixedly installed on the feeding cylinder 4. The outer sleeve 12 extends from the outside of the feeding cylinder 4 into its interior and is fitted onto the rotating shaft 9. Inside the feeding cylinder 4, the outer sleeve 12 prevents the rotating shaft 9 from interfering with the flat pad. Outside the feeding cylinder 4, the outer sleeve 12 provides protection, preventing the rotating shaft 9 from accidentally injuring workers. A guide plate 13 is fixedly installed on the portion of the outer sleeve 12 inside the feeding cylinder 4. The guide plate 13 is a rhomboid sheet structure folded in half to form a triangular pyramid shape. The guide plate 13 is fixed to the outer sleeve 12, with its bottom surface in contact with the inner wall of the feeding cylinder 4, so that one side of the guide plate 13 is in the direction of the flat pad's descent. The guide plate 13 diverts the flat pad, preventing it from accumulating at the position of the outer sleeve 12. The feeding cylinder 4 is conical and inclined, with the side closer to the ground being the bottom surface and the side further away from the bottom surface being the top surface. The bottom surface of the feeding cylinder 4 is provided with several drain holes 14 for discharging excess ammonia water. The drain holes 14 are located at the end of the feeding cylinder 4 away from the distribution shell 2. The equipment is placed above the ammonia water recovery tank, and the ammonia water flows into the recovery tank for recovery through the drain holes 14.

[0033] like Figure 5 As shown, a fan-shaped guide plate 15 is fixed at the connection between the feed cylinder 4 and the distribution shell 2. The guide plate 15 is located on the top surface of the feed cylinder 4 and is inclined to the bottom surface of the feed cylinder 4, so that the flat pad falls on the bottom surface of the feed cylinder 4 after being discharged from the distribution shell 2. After colliding with the feed cylinder 4, the excess ammonia water is discharged through the drain hole 14, preventing the flat pad from falling directly to the outlet of the feed cylinder 4 and reducing the ammonia water recovery effect. A baffle plate 16 is fixed on the inner wall of the top surface of the feed cylinder 4. The baffle plate 16 is located between the drain hole 14 and the guide plate 13, that is, the baffle plate 16 is located at the beginning of the drain hole 14. It blocks the flat pad falling into the feed cylinder 4 and prevents the flat pad from falling too fast and failing to discharge the excess ammonia water.

[0034] In this embodiment, the flat pad is poured into the feeding hopper 3 and falls onto the dispersing plate 5. As the dispersing plate 5 rotates, the ammonia water sprayed by the ammonia water spraying assembly enters the distribution shell 2 through the liquid outlet on the spray chamber 21, so that the flat pad is in an ammonia environment to prevent oxidation after galvanizing. The flat pad collides with the round bar 6 on the dispersing plate 5 and is separated. Under the action of centrifugal force of the dispersing plate 5, it falls into the feeding cylinder 4 through the gap between the distribution shell 2 and the dispersing plate 5. During the falling process, some flat pads fall onto the guide plate 15 and then onto the bottom surface of the feeding cylinder 4 through the guide plate 15. Some flat pads fall directly onto the bottom surface of the feeding cylinder 4. The falling process is diverted by the guide plate 13. All flat pads are blocked by the baffle plate 16 and spread flat on the bottom surface of the feeding cylinder 4. The ammonia water on the flat pads is discharged through the drain hole 14.

[0035] It should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the above embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
