[0001] This utility model relates to the field of graphite production technology, specifically to a crushing device for graphite production. Background Technology
[0002] Graphite is a mineral typically found in metamorphic rocks. It is formed from coal or carbonaceous rocks through regional metamorphism or magmatic intrusion. Graphite is an electrical conductor and a soft, opaque mineral with an oily feel. Its color ranges from iron black to steel gray. It exists in crystalline, flaky, scaly, striped, layered, or dispersed forms within metamorphic rocks. After mining, graphite needs to be crushed to form graphite powder for further processing.
[0003] Existing crushing equipment requires multiple crushing processes when crushing graphite. The equipment structure is complex, and dust is generated during crushing, which can be inhaled into the nasal cavity by crushing personnel, causing dust pollution. Utility Model Content

[0007] As a preferred embodiment of this utility model, the cover plate is close to the three slots, and the width and height of the cover plate match the width and height of the three slots.
[0008] As a preferred technical solution of this utility model, the crushing shaft is provided in two sets, and a number of crushing gears are fixedly connected to the outer edge of each set of crushing shafts. The outer diameter of the number of crushing gears evenly arranged on the outer wall of the crushing shaft is gradually changed, and the diameter of the end of the two sets of crushing shafts closer to the motor is smaller than that of the other end.
[0009] As a preferred embodiment of this utility model, two motors are provided, and the drive ends of the two motors pass through the crushing box and are rotatably connected to the crushing shaft.
[0010] As a preferred technical solution of this utility model, the box cover is convex in shape, the inner wall of the box cover has four slots, the inner wall of the four slots has five slots, the inner wall of the five slots is engaged with a push-pull plate, the outer wall of the push-pull plate is fixedly connected with a push handle, and the inner cavity of the box cover is fixedly connected with a screen plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This graphite production crushing device, through the gradual design of the crushing shaft, is shaped like a frustum with an inclined ramp. This allows the graphite to be crushed into medium-sized pieces at the end of the crushing shaft away from the motor. The medium-sized pieces move to the end of the crushing shaft closer to the motor by gravity. The medium-sized pieces are then screened through the space between the screen plate and the crushing shaft. Medium-sized pieces of suitable size are crushed into small pieces at the end of the crushing shaft closer to the motor. Medium-sized pieces that do not pass through the screen plate remain at the end of the crushing shaft away from the motor and are crushed again. This eliminates the need for multiple crushing processes. After further crushing, small pieces of graphite are obtained and fall onto the screen plate for screening, resulting in uniformly sized small pieces of graphite.
[0014] 2. The graphite crushing device for graphite production uses a push handle to move a sliding plate through five slots. Workers can feed graphite to be crushed through four slots. After feeding, pulling the push handle closes the four slots, preventing dust from flying during crushing and preventing workers from inhaling it into their nasal cavity, thus avoiding pollution.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Please see Figure 1 - Figure 5 The system includes a support leg 1, a crushing box 2 fixedly connected to the top of the support leg 1, a slot 4 opened at the top of the crushing box 2, a discharge port 3 opened on one side of the outer wall of the crushing box 2, two slots 5 opened in the middle inner wall of the crushing box 2, and three slots 6 opened on the side of the inner wall of the crushing box 2 away from the discharge port 3. A cover plate 7 is rotatably connected to the outer wall of the crushing box 2, a screen plate 8 is snapped onto the outer wall of the two slots 5, a crushing shaft 9 is rotatably connected to the middle inner wall of the crushing box 2, a crushing gear 10 is fixedly connected to the outer wall of the crushing shaft 9, a baffle 11 is fixedly connected to the top inner wall of the crushing box 2, a box cover 12 is fixedly connected to the top of the crushing box 2, and a motor 13 is fixedly connected to the side of the outer wall of the crushing box 2 near the discharge port 3.
[0024] The bottom of the inner wall of the slot 4 is inclined, and the top of the inclined surface is close to one end of the inner wall of the crushing box 2, while the bottom of the inclined surface is close to one side of the discharge port 3.
[0025] It should be noted that the crushed graphite pieces are discharged into the discharge port 3 by means of gravity through an inclined setting.
[0026] Among them, the cover plate 7 is close to the three slots 6, and the width and height of the cover plate 7 match the width and height of the three slots 6.
[0027] It should be noted that the cover plate 7 can be opened and closed with the three slots 6 through a rotatable connection with the crushing box 2.
[0028] Among them, there are two sets of crushing shafts 9. Several crushing gears 10 are fixedly connected to the outer edge of each set of crushing shafts 9. The outer diameter of the several sets of crushing gears 10, which are evenly arranged on the outer wall of the crushing shafts 9, is gradually changing. The diameter of the end of the two crushing shafts 9 closest to the motor 13 is smaller than that of the other end.
[0029] It should be noted that the crushing shaft 9 is shaped like a frustum. Several crushing gears 10 on the outer wall of the first crushing shaft 9 are located between two crushing gears 10 on the outer wall of the second crushing shaft 9, and the crushing gears 10 rotate in opposite directions. When the crushing shaft 9 rotates, it drives the crushing gears 10, so that the graphite is crushed at the end of the crushing shaft 9 away from the motor 13. Large graphite at the end of the crushing shaft 9 away from the motor 13 is crushed into medium-sized graphite. The medium-sized graphite moves along the inclined direction of the crushing shaft 9 by gravity and moves to the end of the crushing shaft 9 close to the motor 13. The screen plate 1205 is used to isolate and screen the medium-sized graphite. Medium-sized graphite of suitable size moves through the distance space between the screen plate 1205 and the crushing shaft 9 to the end of the crushing shaft 9 close to the motor 13 and is crushed into small graphite again.
[0030] Two motors 13 are provided, and the drive ends of the two motors 13 pass through the crushing box 2 and are rotatably connected to the crushing shaft 9.
[0031] It should be noted that the starting motor 13 drives the crushing shaft 9 to rotate, and the rotation of the crushing shaft 9 can drive the crushing gear 10 to rotate, thus crushing the graphite.
[0032] The lid 12 is convex in shape. The inner wall of the lid 12 has four slots 1201 and five slots 1202. The inner wall of the five slots 1202 is fitted with a push-pull plate 1204. The outer wall of the push-pull plate 1204 is fixedly connected with a push handle 1203. The inner cavity of the lid 12 is fixedly connected with a screen plate 1205.
[0033] It should be noted that there is a certain distance between the screen plate 1205 and the crushing shaft 9, so that the graphite on the end of the crushing shaft 9 away from the motor 13 is crushed into graphite blocks. Then, the graphite blocks of suitable size can be screened through the distance between the screen plate 1205 and the crushing shaft 9 to the end of the crushing shaft 9 closer to the motor 13 for further crushing. Graphite blocks that do not pass through the distance between the screen plate 1205 and the crushing shaft 9 will remain on the end of the crushing shaft 9 away from the motor 13 for further crushing.
[0034] The baffle 11 is provided in two sets. The two sets of baffle 11 are in the shape of an inverted "V". The lowest point is inclined to the side closer to the crushing shaft 9, and the highest point is located at the top of the crushing box 2.
[0035] It should be noted that two sets of baffles 11 are set to separate the graphite, so that the graphite to be crushed falls between the two crushing shafts 9 for crushing.
[0036] Working principle: The operator opens the cover plate 7, places the sieve plate 8, and then closes the cover plate 7. By starting the motor 13, the operator rotates the crushing shaft 9. The crushing gears 10 on the outer walls of the two crushing shafts 9 rotate accordingly. The operator pulls the push-pull plate 1204 and pours the graphite to be crushed into the four slots 1201. The graphite is crushed on the crushing shaft 9 and crushed into medium-sized pieces that can pass through the space between the sieve plate 1205 and the crushing shaft 9. The medium-sized pieces of graphite move to the end of the crushing shaft 9 near the motor 13 by gravity and are crushed into smaller pieces. Those that cannot pass through continue to be crushed at the end of the crushing shaft 9 away from the motor 13. The crushed small pieces of graphite fall onto the sieve plate 8 for screening. Those that pass the screening fall back to the bottom of the crushing box 2. The inclined design at the bottom of the crushing box 2 allows the crushed small pieces of graphite to be discharged from the discharge port 3.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
