Description

Technical Field

[0001] The utility model relates to the technical field of cast iron inoculants, in particular to a quantitative adding device for cast iron inoculants. Background Art

[0002] Inoculant is a substance that can promote graphitization, reduce the tendency of white cast iron, improve the morphology and distribution of graphite, increase the number of eutectic clusters, and refine the matrix structure. It has a good effect in a short time after inoculation treatment and is mainly suitable for general events or later instantaneous inoculation in various situations.

[0003] The existing methods of adding inoculants are direct injection or manual addition. These two methods will cause discontinuous addition of inoculants, resulting in uneven distribution of inoculants. At the same time, the amount added each time cannot be controlled, and the quantitative addition of inoculants cannot control the speed of addition. To this end, we provide a cast iron inoculant quantitative addition device to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] like Figure 1-6 As shown, the utility model provides a technical solution: a cast iron inoculant quantitative addition device, comprising a shell 1, a quantitative groove 10, an acceleration groove 11 and a control groove 12 are opened on the shell 1, a quantitative mechanism 4 is arranged inside the shell 1 through the quantitative groove 10, a control mechanism 5 is arranged in the control groove 12, and the control mechanism 5 is connected with the quantitative mechanism 4 inside the shell 1, an acceleration plate 7 is arranged in the acceleration groove 11, an adjustment motor 6 is fixed on the surface of the shell 1, and the output shaft of the adjustment motor 6 passes through the shell 1 and is fixed to the acceleration plate 7, an inclined plate 3 is fixed inside the shell 1, and the inclined plate 3 overlaps the surface of the quantitative mechanism 4, the quantitative mechanism 4 is used to use the control mechanism 5 to control the adjustment of the gap size, thereby realizing the quantitative feeding operation, and at the same time, an acceleration plate 7 is arranged below the quantitative mechanism 4, and the angle of the acceleration plate 7 is adjusted by the adjustment motor 6 to control the feeding speed, so as to avoid the blockage and interruption of the inoculant during quantitative feeding, thereby achieving continuous feeding of the inoculant.

[0025] Specifically, Figure 1 , Figure 2 and 4As shown, the quantitative mechanism 4 includes a movable plate 401, a fixed plate 402 and a semicircular plate 403 fixed on the surface of the fixed plate 402. The number of the movable plates 401 is two, and the movable plates 401 are evenly distributed on both sides of the fixed plate 402 and spliced ​​with the fixed plate 402. The movable plate 401 overlaps the inner wall of the shell 1, and the fixed plate 402 and the semicircular plate 403 are fixed to the inner wall of the shell 1. The outermost end of the movable plate 401 is provided with a protrusion, and the movable plate 401 overlaps the quantitative groove 10 through the protrusion. By setting the quantitative mechanism 4 using the movable plate 401 and the fixed plate 402 for splicing, the control of the gap between the movable plate 401 and the fixed plate 402 can be used to achieve quantitative control of the inoculant. At the same time, the use of the inclined plate 3 and the semicircular plate 403 above the movable plate 401 and the fixed plate 402 can make the inoculant better move between the inclined plate 3 and the semicircular plate 403, which is also conducive to feeding through the gap.

[0026] Specifically, Figure 1 , Figure 2 and 4 As shown, the control mechanism 5 includes a dual-axis motor 501, a threaded block 502, a threaded rod 503, a bearing 504 and a rotating shaft 505. The dual-axis motor 501 is arranged in the control slot 12. The output shaft of the dual-axis motor 501 is fixed with a threaded rod 503, and the threads on the surface of the threaded rod 503 are mutually reverse threads. The threaded block 502 is threadedly connected to the surface of the threaded rod 503, and the inner side of the threaded block 502 is fixed to the movable plate 401 in the quantitative mechanism 4. The other end of the threaded rod 503 is fixed with a rotating shaft 505, and the surface of the rotating shaft 505 is sleeved with a bearing 504, and the bearing 504 is embedded in the shell 1. The dual-axis motor 501 is arranged to drive the threaded rod 503 to rotate. The threaded rod 503 with reverse threads can drive the two movable plates 401 to move synchronously through the threaded block 502, so as to achieve more stable adjustment.

[0027] Specifically, Figure 5 and 6 As shown, an auxiliary plate 8 is overlapped below the acceleration plate 7 in the acceleration groove 11, a fixed shaft 13 is passed through the auxiliary plate 8, a spring 9 is clamped on the surface of the fixed shaft 13, and the other end of the spring 9 is clamped with the shell 1, and positioning blocks 2 fixed to the outside are respectively arranged above and below the shell 1, and the positioning blocks 2 are evenly distributed on the surface of the shell 1. The use of spring 9, fixed shaft 13 and auxiliary plate 8 can make use of the elasticity of spring 9 to make the auxiliary plate 8 support the acceleration, avoid the formation of a gap between the bottom of the acceleration plate 7 and the shell 1, and prevent the inoculant from leaking out.

[0028] Working principle: When in use, the staff connects the device with the external cast iron inoculant feeding and discharging device through the upper and lower positioning blocks 2 of the shell 1. The inoculant enters from the top of the device and is discharged from the bottom. When quantitative control is required, the staff starts the dual-axis motor 501 in the control mechanism 5 through external control. The dual-axis motor 501 drives the threaded rod 503 to make the threaded block 502 slide in the control groove 12. At the same time, the threaded block 502 will also drive the movable plates 401 on both sides of the quantitative mechanism 4 to move away from each other, and separate the movable plates 401 from the spliced ​​fixed plates 402. The gap is used for unloading, and the size of the gap is controlled to control the amount of unloading. After passing through the quantitative mechanism 4, the inoculant will accumulate on the surface of the acceleration plate 7. When the inoculant needs to be unloaded at an accelerated rate, the regulating motor 6 is started to adjust the acceleration plate 7 for rotation. When the acceleration plate 7 is opened, it will squeeze the bottom auxiliary plate 8. The fixed shaft 13 in the auxiliary plate 8 will squeeze the spring 9 connected to the shell 1, and the unloading speed can be controlled according to the amount of quantitative unloading.
