Description

Technical Field

[0001] The invention belongs to the technical field of silicon particle inoculant production equipment, and in particular relates to a silicon particle inoculant molding device for producing high-strength ductile iron. Background Art

[0002] Ductile iron is a high-strength cast iron material. Ductile iron is obtained by spheroidizing and inoculating to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron. By adding inoculants that promote graphite formation during the solidification of cast iron, the shape, size and ball density of graphite, as well as the amount of graphite relative to iron carbide, can be controlled.

[0003] Silica inoculant is an important industrial raw material, mainly used in the production of sand cores in the casting process. It consists of three parts: silicate, inoculant and binder. Silicate provides good refractoriness and fluidity, inoculant refines silicate particles, improves product strength and refractoriness, and binder bonds the silica inoculant together to form a sand core.

[0004] The prepared initial silicon inoculant particles are of different sizes and need to be crushed into sand cores of uniform size for use. The crusher has a limited degree of particle crushing. When it is necessary to crush it into smaller particles, the material needs to be repeatedly fed into the crusher for multiple crushing to achieve the effect of small particles.

[0027] A filter screen plate 16 is clamped at the bottom of the inner surface of the crushing and forming machine body 1. A clamping mechanism is symmetrically provided on the crushing and forming machine body 1. The filter screen plate 16 is installed in the crushing and forming machine body 1 through the clamping mechanism. A collecting tank 3 is provided at the bottom of the crushing and forming machine body 1. The collecting tank 3 is used to carry the silicon inoculant particles after molding. A feeding port 2 is provided at the upper end of the crushing and forming machine body 1.

[0028] The supporting mechanism comprises a hydraulic cylinder 10 , a driving end of the hydraulic cylinder 10 is fixedly connected with a driving shaft 11 , and an end of the driving shaft 11 away from the hydraulic cylinder 10 is slidably connected with the hammer disc 5 .

[0029] The hydraulic cylinder 10 is rotatably connected to the upper inner wall of the crushing and forming machine body 1. A slide groove 18 is provided on the surface of the hammer plate 5. A slider 12 is slidably connected to the slide groove 18. The end of the drive shaft 11 away from the hydraulic cylinder 10 is rotatably connected to the slider 12. The support mechanism can change the position of the hammer plate 5 in the crushing and forming machine body 1. When the central shaft 6 rotates, the silicon inoculant will be stirred. The edge positions of the hammer plate 7 and the hammer head 8 will be squeezed with the hammer plate 5. The silicon inoculant can be crushed during the squeezing process. Changing the distance between the hammer plate 7, the hammer head 8 and the hammer plate 5 can change the size of the silicon inoculant particles after crushing. There is space between each hammer plate 7. The reserved space avoids the problem of jamming during crushing.

[0030] The end of the driving shaft 11 away from the hydraulic cylinder 10 is fixedly connected with the first rotating shaft 17, and the first rotating shaft 17 is rotatably connected with the slider 12. The supporting mechanism also includes a first pressing shaft 14 and a second pressing shaft 15 which are rotatably connected together. One end of the second pressing shaft 15 is rotatably connected with the surface of the hammer disc 5, and one end of the first pressing shaft 14 is rotatably connected with the bottom inner wall of the crushing and forming machine body 1. The first rotating shaft 17 is movably connected with the connection between the first pressing shaft 14 and the second pressing shaft 15. When the hydraulic cylinder 10 pushes the driving shaft 11 to move through the driving end, due to the limited action point of the driving shaft 11, the second pressing shaft 15 is connected through the connecting shaft 13, and the second pressing shaft 15 is slidably connected with the hammer disc 5. The second pressing shaft 15 is additionally provided for support, thereby ensuring the stability of the position of the hammer disc 5.

[0031] The lower end of the connecting shaft 13 is rotatably connected with the second rotating shaft 19, and the second rotating shaft 19 simultaneously penetrates through one end connected with the first pressing shaft 14 and the second pressing shaft 15, and the first pressing shaft 14 and the second pressing shaft 15 are rotatably connected together through the second rotating shaft 19. The connecting shaft 13 is simultaneously connected with the first pressing shaft 14 and the second pressing shaft 15 through the second rotating shaft 19, and the connection between the first pressing shaft 14 and the second pressing shaft 15 is also realized through the second rotating shaft 19.

[0032] The driving motor 4 is fixedly mounted on the surface of the crushing and forming machine body 1, the driving end of the driving motor 4 is fixedly connected to the central shaft 6, a limit plate 9 is arranged on the inner wall of the crushing and forming machine body 1, and the upper end of the hammer plate 5 is slidably connected to the limit plate 9. The driving motor 4 drives the central shaft 6 to rotate through the driving end.

[0033] The clamping mechanism includes a clamping shaft 21, and concave shafts 20 used in conjunction with the clamping shaft 21 are provided at both ends of the filter screen plate 16. A groove 23 is provided on the surface of the crushing and forming machine body 1, and a spring 22 is provided in the groove 23. The spring 22 is fixedly connected to one side of the clamping shaft 21, and the concave shaft 20 is clamped inside the clamping shaft 21. When installing the filter screen plate 16, after the filter screen plate 16 is inserted into the bottom of the crushing and forming machine body 1, the clamping shaft 21 is clamped on the outside of the concave shaft 20 under the elastic force of the spring 22, thereby fixing the position of the filter screen plate 16.

[0034] The silicon granule inoculant to be crushed is fed into the crushing and molding machine body 1 through the feeding port 2, and the driving motor 4 drives the central shaft 6 to rotate through the driving end. As the central shaft 6 rotates, the hammer plate 7 and the hammer head 8 can be driven to rotate. During the rotation, the edges of the hammer plate 7 and the hammer head 8 will be squeezed with the hammer plate 5 to crush the silicon granule inoculant particles in between. The crushed particles are filtered by the filter plate 16, and the crushed silicon granule inoculant will be collected in the collecting tank 3.

[0035] According to the needs of production and preparation, the required silicon particle inoculant particles have different sizes, so the position of the hammer disc 5 in the crushing and molding body 1 is adjusted, and the hydraulic cylinder 10 is started. The hydraulic cylinder 10 can extend and retract the drive shaft 11 through the drive end. The drive shaft 11 extends and pushes the slider 12 to slide downward along the slide groove 18. The drive shaft 11 drives the connecting shaft 13 to move downward through the slider 12. The connecting shaft 13 pushes the second rotating shaft 19, so that the angle between the first pressure shaft 14 and the second pressure shaft 15 becomes larger, thereby pushing the hammer disc 5 to get closer to the hammer head 8, so as to crush and mold smaller particles, and vice versa, crush and mold larger particles.

[0036] Different sizes of filter plates 16 are required for molding different particles. The filter plate 16 can be detached and replaced through a snap-fit ​​mechanism. After the filter plate 16 is inserted from one side of the crushing and molding body 1, the snap-fit ​​shaft 21 is snap-fitted with the concave shaft 20 under the elastic force of the spring 22. The filter plate 16 is restricted by limiting the concave shaft 20, so that the filter plate 16 can be fixed.
