[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 In an embodiment of the utility model, a graphene oxide cake crushing device includes a feed hopper for crushing graphene oxide cakes, the feed hopper has two symmetrically arranged support wall panels 1 with an L-shaped longitudinal section, and an end plate is fixed at both ends of the two support wall panels 1;

[0031] Crushing rollers, two crushing rollers for crushing graphene oxide cakes are provided, and the crushing rollers have a driving shaft 5 and a crushing blade 6; the crushing blades 6 are provided in plurality, and the plurality of crushing blades 6 are arranged in a uniform array along the axial direction of the driving shaft 5;

[0032] The crushing blades 6 are arranged in two groups, 12 in one group, and the two groups of crushing blades 6 are alternately engaged;

[0033] The crushing blade 6 is made of 2507 stainless steel, and the single size is about 200*110*25mm, in the shape of a barb;

[0034] The supporting wall panel 1 is made of 2507 stainless steel.

[0035] By adopting the above technical solution, when in use, the cake material is first placed in the meshing position of the two sets of crushing blades 6. As the crushing blades 6 rotate and alternately mesh, the cake material is quickly torn; and the material of the supporting wall panel 1 is 2507 stainless steel, which has high corrosion resistance. The cake material is crushed on the inner side of the supporting wall panel 1 to prevent the graphene oxide cake from corroding other parts of the equipment.

[0036] In this embodiment, a frame body 2 for supporting is provided at the bottom of the supporting wall panel 1, and a power assembly is also provided on the side of the supporting wall panel 1 away from the cylindrical gear 7. The power assembly includes a reducer 3 and a variable frequency motor 4 for providing power, and the output shaft of the variable frequency motor 4 is connected to the output shaft of the reducer 3.

[0037] In this embodiment, the power assembly further includes a coupling located at the end of the output shaft of the reducer 3 , and the other end of the coupling is connected to the end of the driving shaft 5 .

[0038] In this embodiment, the front and rear ends of the driving shaft 5 extend to the front and rear ends of the outer side of the supporting wall panel 1 respectively, and the connection is fixed by a bearing, and the outer ring of the bearing is fixed to the outer side of the supporting wall panel 1.

[0039] In this embodiment, the crushing blade 6 is completely located in the cavity of the supporting wallboard 1 , thereby separating the crushing blade 6 from the reducer 3 and the cylindrical gear 7 .

[0040] By adopting the above technical solution, after the cake material is placed inside the supporting wallboard 1 , the cake material will not leave the inside of the supporting wallboard 1 regardless of whether the crushing blade 6 rotates forward or reversely.

[0041] In this embodiment, the driving shafts 5 distributed at the front and rear ends are rotated simultaneously by cylindrical gears 7 installed at the ends, and two sets of crushing blades 6 can be driven by one motor, which saves energy consumption and reduces the floor space of the equipment.

[0042] In this embodiment, a discharge port is provided on the upper portion of the frame body 2, and the discharge port is located at the lower portion of the supporting wall panel 1, and the cake material crushed inside the supporting wall panel 1 will fall downward through the discharge port.

[0043] By adopting the above technical solution, the variable frequency motor 4 drives the crushing blade 6 to rotate forward and reverse frequently, so that the acidic material adhered to the crushing blade 6 can be peeled off in time, which can prevent the graphene oxide block material from adhering and hardening for a long time, and then damaging the blade during operation. At the same time, the hardened graphene oxide block material falls off and enters the graphene oxide finished product, which is a foreign matter and causes product pollution.

[0044] The working principle of the utility model is: when in use, first put the graphene oxide cake into the inner side of the supporting wall panel 1, then adjust the rotation speed of the output shaft of the frequency conversion motor 4 through the reducer 3, and then the output shaft of the reducer 3 drives the driving shaft 5 to rotate through the coupling, and then the two sets of alternately meshed crushing blades 6 are used to tear the cake through the cylindrical gear 7. The supporting wall panel 1 isolates the material crushing operation area from other areas, effectively preventing the acidic material from corroding other areas of the equipment and extending the service life of the equipment.

[0045] When the cake material is adhered to the outside of the crushing blade 6, the rotation speed and rotation direction of the output shaft of the frequency conversion motor 4 can be adjusted to make the crushing blade 6 rotate forward and reverse frequently, and the graphene oxide block material adhered to the blade can be peeled off, and the graphene oxide block material can be recovered in time, reducing production costs, and the adhered acidic materials can be peeled off in time, which can prevent the graphene oxide block material from adhering and hardening for a long time, and then damaging the blade during operation. At the same time, the hardened graphene oxide block material falls off and enters the graphene oxide finished product, which is a foreign matter and causes product pollution.
