It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Please also read Figures 1 to 3 , the wet material pulverizing device provided by the present invention is now described. The wet material pulverizing device comprises a pulverizing mechanism 1, a feeding component 2, a step tooth structure 5, a discharging component 3 and a driving mechanism 4. The pulverizing mechanism 1 is composed of multiple groups, and the multiple groups of pulverizing mechanisms 1 are stacked up and down. Two adjacent groups of pulverizing mechanisms 1 are connected to each other and are used for wet material to pass through. The lower end of the adjacent and upper pulverizing mechanism 1 is provided with a plurality of pulverizing components 11 for extending into the interior of the pulverizing mechanism 1 located below and for crushing the wet material. From top to bottom, the plurality of pulverizing components 11 gradually reduce the pulverizing particle size of the wet material. The feeding component 2 is provided at the upper end of the top pulverizing mechanism 1 and is connected to the interior of the pulverizing mechanism 1, and is used for feeding into the pulverizing mechanism 1. The step tooth structure 5 is provided inside the top pulverizing mechanism 1. , including a dynamic grinding disc 51 arranged on a driving mechanism 4 and a static grinding disc 52 fixed inside a pulverizing mechanism 1. The dynamic grinding disc 51 rotates with the aid of the driving mechanism 4 and is aligned with the static grinding disc 52 up and down, and is used to extrude and crush the material. The dynamic grinding disc 51 and the static grinding disc 52 are both step-shaped structures and are symmetrically arranged. The thickness of the step-shaped structure increases from the inside to the outside. The material is squeezed and crushed from the inside to the outside between the dynamic grinding disc 51 and the static grinding disc 52; the discharging component 3 is arranged in the middle of the pulverizing mechanism 1 at the bottom, and is used to output the crushed wet material located in the pulverizing mechanism 1 at the bottom; the driving mechanism 4 passes through the interior of multiple groups of pulverizing mechanisms 1 from top to bottom in sequence, and is used to cooperate with multiple pulverizing components 11 to pulverize the wet material at the same time.

[0022] The wet material pulverizing device provided by the present invention is compared with the prior art. In the wet material pulverizing device of the present invention, the driving mechanism 4 rotates in multiple groups of pulverizing mechanisms 1, and cooperates with multiple pulverizing components 11 to extrude each other. The wet material can be pulverized by extruding the pulverizing mechanism 1 and the driving mechanism 4. The multiple groups of pulverizing mechanisms 1 are stacked up and down, and the pulverizing particle size of the wet material by the multiple pulverizing components 11 is gradually reduced from top to bottom. The material is fed into the pulverizing mechanism 1 through the feeding component 2, and the material is discharged from the bottom pulverizing mechanism 1 through the discharging component 3. The wet material is gradually crushed from top to bottom in the multiple groups of pulverizing mechanisms 1, and finally the pulverizing effect is achieved, which solves the technical problems of long pulverizing operation time and low pulverizing efficiency for the wet material. The pulverizing operation time for the wet material is short, the wet material is crushed more evenly in the pulverizing mechanism 1, the pulverizing requirements can be met, the pulverizing efficiency is high, and the technical effect of meeting the operation progress of the pulverizing process is met.

[0023] Wet material refers to material that may be agglomerated, or material with high humidity, or spherical. The extrusion force generated between the driving mechanism 4 and the crushing component 11 can gradually break up the wet material until it is squeezed and crushed. The final material flows out from the discharging component 3. The output material can meet the crushing requirements for the wet material, meet the production indicators, and does not affect the production efficiency.

[0024] The driving mechanism 4 cooperates with the crushing assembly 11 on each group of crushing mechanisms 1 during the rotation process. The two are not in contact. When the wet material falls naturally, it will pass between the two and be crushed by the extrusion force between the driving mechanism 4 and the crushing assembly 11 during the rotation. The wet material is gradually crushed, thereby achieving the purpose of crushing. The crushing assembly 11 is set on the crushing mechanism 1 and is stationary, while the main active part is the driving mechanism 4. The crushing part of the driving mechanism 4 gradually decreases the distance from the crushing assembly 11 during the rotation, thereby achieving the effect of gradually squeezing and crushing the wet material.

The material enters from the feeding assembly 2 and reaches the inside of the pulverizing mechanism 1. In the process of natural falling, it is squeezed by the squeezing force between the driving mechanism 4 and the pulverizing assembly 11.

[0026] The upper connecting portion 13 and the lower connecting portion 14 are both flanges for realizing the connection between adjacent pulverizing mechanisms 1. A plurality of bolts are arranged on the flange along the circumferential direction, and the adjacent upper connecting portion 13 and the lower connecting portion 14 can be locked by the bolts.

By providing a gasket, the first stud 111 can be limited to the lower connecting portion 14, and the first stud 111 can be locked by the first nut 112.

[0028] As a specific embodiment of the wet material pulverizing device provided by the present invention, please refer to Figures 1 to 3 A circular baffle 15 is provided at the bottom of the shell 12.

A gap is provided between the outer end of the circular baffle 15 and the inner wall of the shell 12. The gap is used for the wet material to flow into the shell 12 located below. The end of the circular baffle 15 is fixed to the inside of the shell 12 through a plurality of connecting rods (not shown in the figure). The wet material passes through the gap and reaches the shell 12 below, and enters the area between the crushing assembly 11 and the crushing part 43 of the driving mechanism 4, so as to be crushed.

[0029] Specifically, a circular baffle 15 is also provided at the inner bottom of the feed assembly 2, which has the same function as the circular baffle 15 in the pulverizing mechanism 1. The feed assembly 2 is a wide-mouth structure, which is convenient for feeding from above.

The wet material is crushed by the extrusion force between the crushing assembly 11 and the driving mechanism 4. The guide plate 16 can smoothly guide the wet material to the area between the crushing assembly 11 and the crushing part 43 of the driving mechanism 4, preventing the material from entering the middle of the housing 12 and preventing the material from not being crushed.

The driving shaft 42 is connected to the circular baffle 15 in a rotational connection, or the rotational connection can be achieved through a bearing member, that is, the driving shaft 42 passes through the multiple circular baffles 15 and does not drive the multiple circular baffles 15 to rotate. On the contrary, if the circular baffle 15 is fixed on the drive shaft 42, the function of blocking and guiding the wet material can also be achieved. Therefore, it does not matter whether the drive shaft 42 and the circular baffle 15 are rotationally connected or not, and the function of the present invention can be achieved.

The dynamic grinding disc 51 and the static grinding disc 52 are aligned in the vertical direction and arranged in a symmetrical manner, so that the material is squeezed and crushed from the inside to the outside by the centrifugal force acting on the disc 431 in the space surrounded by the dynamic grinding disc 51 and the static grinding disc 52. Due to the structural characteristics of the step teeth, the gap gradually becomes smaller from the inside to the outside. During the rotation, due to the collision of the dynamic and static teeth, the material is initially crushed from large to small, which can fully pre-crush large particles and avoid the needle-shaped teeth being blocked by large particles, affecting the material crushing and causing machine blockage.
