Description

Technical Field

[0001] The utility model relates to the technical field of stone mill processing, in particular to a graphite raw material coarse crushing device. Background Art

[0002] In the carbon industry, the largest production volume is a variety of artificial graphite products, which are generally made of easily graphitized petroleum coke and asphalt coke as raw materials, and are made through a series of processes such as batching, kneading, molding, roasting, graphitization (high temperature heat treatment) and mechanical processing. In the preparation process of graphite, the raw materials need to be crushed. At this time, various crushers and pulverizers are mostly used for operation.

[0003] For example, the patent with application number "CN202223126194.9" discloses a graphite ball raw material coarse crushing device, including a coarse crusher shell, an outer wall on one side of the coarse crusher shell is provided with a discharge port, two electric telescopic rods are fixedly connected to the outer wall on one side of the coarse crusher shell, and the same baffle is fixedly connected to the output shafts of the two electric telescopic rods, and the baffle is slidably connected to the outer wall near the discharge port, a collecting box is fixedly connected to the outer wall on one side of the coarse crusher shell, and the collecting box is located below the discharge port, the coarse crusher shell is provided with an opening, and the inner wall of the opening is movably connected with a box door. The patent with application number "CN202321215515.4" discloses a raw material coarse crushing device, including an outer shell and an auxiliary structure, wherein a cabinet door is rotatably connected to the interior of the outer shell, a filter screen is provided inside the outer shell, and the filter screen is connected to the outer shell with the aid of the auxiliary structure, a feed trough is fixedly connected to the upper surface of the outer shell, and a protective structure is provided on the arc surface of the feed trough, and the protective structure includes a limit block, which is fixedly connected to the feed trough, and the inner wall of the limit block is rotatably connected to a shaft rod, and the arc surface of the shaft rod is fixedly connected to a connecting block, and the end of the connecting block away from the shaft rod is fixedly connected to a protective plate, and the protective plate and the end of the feed trough away from the limit block are both fixedly connected to connecting plates.

[0004] The above two public technologies and the conventional crushing equipment currently on the market can meet the requirements of coarse crushing of graphite raw materials. However, there are still some shortcomings. For example, in order to facilitate feeding, a bucket-shaped feed port is often used; the strength of its outward expansion structure is relatively low, and the raw materials continuously fall on the feed port, which makes it burdened and easy to damage. Moreover, after the raw materials enter the interior, they hit the inner wall and are also prone to certain damage. Moreover, the raw materials fall directly on the crushing assembly, with a fast falling speed and a large impact force, which also has an adverse effect on the overall life of the equipment.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0044] Reference Figure 1-11 A graphite raw material coarse crushing device includes a square shell 1, and a support leg is arranged below the square shell 1 or the square shell 1 is directly placed on the ground; an outward-expanded feed hopper 2 is arranged above the square shell 1 to form a sufficiently large feed surface.

[0045] Meanwhile, a plurality of reinforcing ribs 3 are arranged at intervals on the outer side of the feed hopper 2 .

[0046] like Figure 1 , 2 , 4, and 5; the reinforcing rib 3 is triangular in shape, fixed to the lower side of the feed hopper 2, and fixed to the outer side of the square shell 1 to form a support under the feed hopper 2; thereby, the strength and bearing capacity of the feed hopper 2 can be significantly improved, and it is not easy to deform when impacted by raw materials.

[0047] In some embodiments, two sets of crushing rollers 4 are symmetrically arranged inside the square housing 1 .

[0048] like Figure 3 , 4 As shown, each group of crushing rollers 4 consists of two, and the two crushing rollers 4 rotate relative to each other to squeeze and crush the graphite raw material between them.

[0049] Correspondingly, no crushing operation is performed between the two groups of crushing rollers 4.

[0050] In addition, in order to reduce the graphite raw material from falling between the two groups of crushing mills 4 and reducing the efficiency, an arc-shaped protective plate 5 arranged along the axial direction is provided at the middle position above the crushing mill 4.

[0051] like Figure 3 , 4 As shown, the arc-shaped protective plate 5 blocks the graphite raw material from falling into the middle position; at the same time, it also provides protection to reduce the direct impact of the graphite raw material on the crushing roller 4; during use, the arc-shaped protective plate 5 can be regularly inspected and replaced; it is easy to maintain and has low maintenance costs.

[0052] Furthermore, inclined plates 6 are provided above both ends of the crushing roller 4 .

[0053] like Figure 1-6 As shown, the inclined plates 6 on both sides prevent the graphite raw materials from falling on the end of the crushing mill 4 to form blockage and jam; at the same time, the impact of the graphite raw materials on the square shell 1 is reduced, reducing its damage; in addition, the inclined plates 6 form an inclined surface, which slows down the speed at which the graphite raw materials fall on the crushing mill 4, reduces the impact force, and can also reduce the occurrence of splashing.

[0054] In some embodiments, a discharge plate 7 is disposed below the crushing roller 4 .

[0055] Among them, the discharge plate 7 is composed of two symmetrical inclined plates; the inclined plates are inclined and lowered toward the outer sides away from each other; thus, discharge can be carried out on both sides at the same time, which significantly speeds up the discharge speed and is more efficient.

[0056] Furthermore, triangular ribs 71 are arranged at intervals below the discharge plate 7 to improve the strength and reliability of the discharge plate 7 .

[0057] like Figure 2 As shown; a plurality of triangular ribs 71 are provided.

[0058] In some embodiments, a buffer assembly 8 is disposed at the upper inner portion of the square housing 1 to provide protection through its own buffering effect.

[0059] Specifically, the buffer assembly 8 includes two side frames 81 that are hingedly arranged to form a triangle; the inner ends of the two side frames 81 are hingedly connected via a main shaft 82 .

[0060] The side frame 81 includes: a main rod 811 with both ends clamped on the square shell 1 for horizontal sliding, and side rods 812 fixed on the main rod 811 in rows; sleeves 813 are set at the ends of the side rods 812 and are sleeved on the main shaft 82; the side rods 812 of the two side frames 81 are staggered.

[0061] Correspondingly, the square housing 1 is provided with a horizontal strip hole 11 corresponding to the main rod 811, and a vertical strip hole 12 corresponding to the main shaft 82. At the same time, elastic rods 9 are respectively provided below both ends of the main rod 811 to provide restoring force thereto.

[0062] It can be understood that the elastic rod 9 is fixed to the outside of the square housing 1 ; preferably, a support plate is provided on the outside of the square housing 1 for mounting the elastic rod 9 .

[0063] like Figure 3-5 7-11; in normal state, supported by the elastic rod 9, the main shaft 82 moves upward in the vertical strip hole 12; accordingly, the two side frames 81 are driven to gather in the middle. After being impacted by the graphite raw material, the main shaft 82 is pressed down, and the two side frames 81 are expanded outward to form a buffer and unload force.

[0064] In some embodiments, a protective top plate 83 is provided above the main shaft 82 via a connecting rod.

[0065] like Figure 9-11 As shown; the impact and damage to the main shaft 82 are reduced by protecting the top plate 83; and the entry of fine particles between the sleeve 813 and the main shaft 82 can be reduced.

[0066] In some embodiments, the outside of the square housing 1 is provided with: a protective cover 13 covering the horizontal strip holes 11 and the vertical strip holes 12 .

[0067] When the utility model is used, the crushed graphite raw material is added through the feed hopper 2; the graphite raw material is partially blocked by the arc-shaped protective plate 5, the inclined plate 6, and the buffer component 8; after the crushing roller 4 crushes the graphite raw material, it is discharged outward through the discharge plate 7.

[0068] In the utility model, an outwardly expanded feed hopper 2 is provided to form a sufficiently large feed surface; a plurality of reinforcing ribs 3 are provided on the outside of the feed hopper 2 to significantly improve the strength and bearing capacity of the feed hopper 2, and it is not easy to deform when impacted by the raw materials; an arc-shaped protective plate 5 is provided in the middle position to prevent the graphite raw materials from falling into the middle position; at the same time, the direct impact of the graphite raw materials on the crushing mill 4 is reduced; the arc-shaped protective plate 5 is regularly inspected and replaced, and the maintenance is convenient and the maintenance cost is low; an inclined plate 6 is provided to prevent the graphite raw materials from falling on the end of the crushing mill 4 to form blockage and jamming; at the same time, the impact and damage of the graphite raw materials on the square shell 1 are reduced; at the same time, an inclined surface is formed to slow down the speed at which the graphite raw materials fall on the crushing mill 4, reduce the impact force, and reduce splashing; the discharge plate 7 is composed of two symmetrical inclined plates, and discharges on both sides at the same time, which speeds up the discharge speed and is more efficient; a buffer component 8 is provided to provide protection through its own buffering effect.
