Description

Crushing gear ring for needle coke crushing

Technical Field

The utility model relates to a broken field of needle coke especially relates to a be used for broken ring gear of needle coke.

Background

The needle coke is a high-quality variety developed greatly in carbon materials, is a porous solid with silver gray and metallic luster in appearance, has obvious flowing textures in structure, is large and few in holes and slightly elliptical, has larger length-width ratio of particles, has fibrous or needle-shaped texture trend and lubricating feeling when being touched, and is a raw material for producing high-end carbon products such as ultrahigh-power electrodes, special carbon materials, carbon fibers and composite materials thereof. Needle coke needs to be broken in a grading way firstly in the storage and transportation process to reach a certain granularity, so that the needle coke is convenient to transport and store.

SUMMERY OF THE UTILITY MODEL

For solving the problem that causes excessive breakage and blockage easily in the current needle coke breakage, the utility model provides a broken ring gear for needle coke breakage.

The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be: a broken ring gear for needle coke breaking is prepared as setting a four-face cone projected outward along ring gear tangential on same side of multiple broken teeth along ring gear circumferential direction, connecting big end of said four-face cone to external circumferential surface of broken teeth along radial external edge of ring gear, connecting big end of said four-face cone to edge of a section of circular tooth slot on broken teeth along radial internal edge of ring gear, setting concave direction of circular tooth slot to be opposite to convex direction of adjacent four-face cone, setting length of circular tooth slot to be equal to axial width of broken teeth along ring gear, setting a transition plane on two sides of four-face cone along ring gear axial direction, setting two transition planes and big end of adjacent four-face cone on same reference plane parallel to ring gear axial direction and setting two transition planes to be same along ring gear axial width.

Preferably, three crushing teeth are uniformly distributed on the gear ring along the circumferential direction of the gear ring at intervals.

Preferably, the included angle of the conical surfaces of the four-sided pyramids is 50-65 degrees, and the small ends of the four-sided pyramids are in smooth transition.

Preferably, the small end of the four-sided cone protrudes from the crushing tooth by a distance of 50-70mm, and the width of the transition plane along the axial direction of the gear ring is 30-50 mm.

According to the technical scheme, the beneficial effects of the utility model are that:

the utility model provides a broken ring gear for needle coke breakage, through set up the four sides cone on broken tooth, when making broken tooth and material rotary contact, can contact with the material by the tip of four sides cone earlier, contact area increases gradually again afterwards, can effectively avoid the material to take place excessively crushing in the crushing process, has reduced the excessive crushing rate of material; the two sides of the big end of the four-side cone are provided with the transition planes, one side of the four-side cone is provided with the arc tooth socket, and the materials crushed by the four-side cone can be crushed for the second time through the matching of the arc tooth socket and the two sections of transition planes, so that the crushing process is divided into multiple times, the crushing effect can be finally ensured, the excessive crushing of the materials due to the overlarge acting force at the moment of collision when the materials are contacted with the crushing teeth can be avoided, and the excessive crushing rate of the materials can be further reduced; the material can be pushed in the crushing process through the two transition planes, so that the material can keep a motion state in the crusher, the material is effectively prevented from being accumulated and blocked between the crushing teeth, and the requirement on high-efficiency and high-quality production of needle coke can be met.

The labels in the figure are: 1. crushing teeth, 2, four-side cones, 3, arc tooth grooves, 4 and transition planes.

Detailed Description

Referring to the drawings, the specific embodiments are as follows:

a broken ring gear for needle coke breaking, distribute three broken teeth 1 evenly along the self circumference interval on the ring gear, three broken tooth 1 is equipped with a section of four-sided cone 2 that projects outwards along the ring gear tangential direction on the same side along the ring gear circumference, the conical surface included angle of the four-sided cone 2 is 50-65 degrees, the tip of the four-sided cone 2 is smooth and smooth, the distance that the tip of the four-sided cone 2 projects from the broken tooth 1 is 50-70mm, the outer side edge of the radial direction of the ring gear of the tip of the four-sided cone 2 is connected with the outer circumferential surface of the broken tooth 1, the inner side edge of the radial direction of the ring gear of the tip of the four-sided cone 2 is connected with the edge of a section of circular arc tooth socket 3 on the broken tooth 1, the concave direction of the circular arc tooth socket 3 is opposite to the convex direction of the adjacent four-sided cone 2, the length of the circular arc tooth socket 3 is equal, the two transition planes 4 and the big ends of the adjacent four-side cones 2 are positioned on the same reference surface which is parallel to the axial direction of the gear ring, and the widths of the two transition planes 4 along the axial direction of the gear ring are the same and are both 30-50 mm.

The utility model discloses when carrying out the breakage to the material, can be earlier by the tip of four sides cone 2 with the material contact, area of contact increases gradually again afterwards, then the material can contact with circular arc tooth's socket 3 and two sections transition planes 4, can carry out the secondary crushing to the material after the breakage of four sides cone 2, thereby divide the crushing process into going on many times, can enough finally guarantee crushing effect, also avoided the material too big excessively to smash because of the effort in the moment of collision when contacting with crushing tooth 1, reduced the excessive crushing rate of material; the material can be pushed in the crushing process through the two sections of transition planes 4, so that the material can keep a motion state in the crusher, the blockage caused by the accumulation of the material between the crushing teeth 2 is effectively avoided, and the smooth operation of the needle coke crushing process is ensured.
