Description

Technical Field

[0001] The utility model mainly relates to the technical field of crushing equipment, in particular to a multi-group knife crushing device for artificial graphite coke raw materials. Background Art

[0002] Artificial graphite coke is a man-made material with low ash and sulfur content, and is an ideal carbon material that is easy to graphitize. When making paper cup artificial graphite electrodes, the artificial graphite coke raw materials need to be crushed and pre-treated to obtain a suitable particle size to facilitate the subsequent calcining furnace drying process.

[0003] Currently, most common crushing equipment is double-roll crusher. When the belt conveyor line transports the raw materials to the crushing equipment for crushing, large pieces of material cannot be crushed normally, causing blockage of the feed port, or the particle size of the crushed material is too large to pass through the filter and requires secondary crushing. It is necessary to set up a conveyor line to perform secondary transfer operations on the material, resulting in low material crushing efficiency and easy blockage of the feed port in the current traditional double-roll crusher.

[0004] The inventor proposed a multi-set knife crushing device for artificial graphite coke raw materials. By improving the traditional double-roll crushing structure and adopting a four-axis crusher assembly, the crushing efficiency of the equipment for materials is improved. At the same time, the structural design of the four-axis crushing roller realizes an increase in the feed port area of ​​the crushing device. Utility Model Content

[0036] See attached Figure 1-4 The utility model provides a multi-set knife crushing device for artificial graphite coke raw materials, comprising the following structure:

[0037] A crushing box 1 has at least four crushing rollers 2 movably connected at equal intervals inside the crushing box 1 , and a feed hopper 7 is provided on the top of the crushing box 1 .

[0038] Conveyor belt: a dust cover 4 is fixedly arranged on the outer side of the conveyor belt.

[0039] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a bracket 5 is fixedly provided on the outside of the crushing box 1, and mounting plates are fixedly provided on the left and right sides of the bracket 5. A reducer 52 is fixedly provided on the top of the mounting plate, and a crushing motor 53 is fixedly provided at the input end of the reducer 52. The output end of the reducer 52 is fixedly connected to the end of the crushing roller 2.

[0040] The crushing motor 53 and the reducer 52 cooperate to complete the driving setting of the four crushing rollers 2 arranged horizontally in the crushing box 1, and complete the crushing process of the artificial graphite coke raw material by the four crushing rollers 2 in the crushing box 1.

[0041] In this embodiment, Figure 2 and Figure 3 As shown, four crushing rollers 2 are horizontally arranged from the front to the rear of the crushing box 1, and the tearing teeth of the four crushing rollers 2 are staggered.

[0042] The design of four horizontally arranged crushing rollers 2 increases the working surface area for material crushing and increases the feed port area on the top of the crushing box 1. When the amount of material in the feed hopper 7 increases sharply, the artificial graphite coke raw material is processed through the enlarged material crushing working surface to avoid accumulation and blockage of the artificial graphite coke raw material on the crushing rollers 2.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a discharge hopper 6 is fixedly provided at the bottom of the crushing box 1 , and a discharge valve 61 is fixedly provided in the middle of the discharge hopper 6 .

[0044] The discharge hopper 6 and the discharge valve 61 cooperate to discharge the crushed material in the crushing box 1 onto the short-distance conveyor belt 3, and the material is transported to the conveyor belt equipment on the artificial graphite production line via the short-distance conveyor belt 3. Therefore, during the installation of this equipment in the factory, there is no need to consider the position design of the conveyor belt equipment on the production line and the discharge hopper 6. The transition feeding design of the short-distance conveyor belt 3 facilitates the installation of this equipment.

[0045] At the same time, a short-distance conveyor belt 3 is arranged at the discharge port of the discharge hopper 6. Compared with the maintenance of the long-distance conveyor belt equipment on the production line, the impact and wear of the short-distance conveyor belt 3 caused by the falling materials can be borne by the short-distance conveyor belt 3 with a transitional design, which effectively reduces the operation and maintenance costs of the equipment.

[0046] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a feed port is fixedly provided on the top of the dust cover 4 , and the feed port of the dust cover 4 cooperates with the discharge port at the bottom of the discharge hopper 6 .

[0047] The design of the dust cover 4 is to shield the dust generated during the material transportation process.

[0048] In this embodiment, Figure 4 As shown, the bottom of the feed hopper 7 is movably connected to the top of the crushing box 1, a vibration motor 71 is fixedly provided on the rear side of the feed hopper 7, spring damping shock-absorbing frames 72 are fixedly provided on the left and right sides of the feed hopper 7, and a truss 73 is fixedly provided at the bottom of the spring damping shock-absorbing frame 72.

[0049] Taking into account the possible material jamming problem in the feed hopper 7, the vibration motor 71 and the spring damping shock-absorbing frame 72 cooperate to realize the feed hopper 7 to provide vibration feeding operation for the crushing box 1, wherein the spring damping shock-absorbing frame 72 can select a conventional spring damping shock-absorbing product or a gas spring damping shock-absorbing product.

[0050] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
