[0026] Embodiment 1

[0027] Please refer to Figure 1, an embodiment of the present utility model provides a pulverizer for drying wet mud, which includes a frame and an abrasive component; the frame is used to install and support various parts of the pulverizer. Since the pulverizer reduces the particle size of the material to an extent that it can be discharged by colliding and squeezing the material through the toner component, certain vibrations will be generated during the collision and extrusion. The stability of the pulverizer is maintained by the frame so that it can complete normal processing. There are a first support part and a second support part on the frame. The first support part and the second support part are arranged at both ends of the frame and are respectively used to install different components.

[0028] The first support part is provided with a pulverizing component. The first support part is provided with a feed cavity 11, an abrasive cavity 12 and a discharge cavity 13. The feed cavity 11, the abrasive cavity 12 and the discharge cavity 13 are arranged through an external housing. The top plates 121 of the feed cavity 11 and the abrasive cavity 12 are arranged together and installed on the frame. The bottom plate of the abrasive cavity 12 is directly installed on the frame. The discharge cavity 13 is integrally installed on the frame and covers the entire exterior of the bottom plate. The connections between the housings of the feed cavity 11, the abrasive cavity 12 and the discharge cavity 13 and the frame all adopt flange connections, and the flanges are fastened by bolts and nuts.

[0029] Please refer to Figure 1 , the abrasive cavity 12 is arranged in a cylindrical shape. When the rotor 21 drives the abrasive teeth 213 to rotate, the cylindrical abrasive cavity 12 can cover its entire range. If a rectangular abrasive cavity 12 is used, there will always be dead corners during abrasion. And the abrasive cavity 12 can make the material perform cyclic abrasion, rather than being directly discharged after one-time abrasion. The rotor 21 and the abrasive teeth 213 drive the material to perform a cyclic abrasion operation in the abrasive cavity 12 until the discharging is completed.

[0030] Please refer to Figure 3, a power component is provided on the second support portion, and the power component drives the abrasive component to enable it to have the power to circulate the abrasive. The abrasive component is arranged in the abrasive cavity 12; the abrasive component includes a rotor 21 and a plurality of partition disks 211 arranged at intervals on the rotor 21; an installation groove 212 is formed between every two partition disks 211; an abrasive tooth 213 is arranged in each installation groove 212. Through the arrangement of the partition disks 211 and the installation grooves 212, a plurality of abrasive teeth 213 can be installed. If a whole piece of abrasive tooth 213 is arranged, the abrasive effect is not good. Generally, the parts that can perform abrasion are the two ends of the abrasive tooth 213. By arranging a plurality of abrasive teeth 213, the contact positions between the material and the abrasive teeth 213 are increased, so that it can be fully abraded. The abrasive tooth 213 is arranged as a rectangular block, which increases its edges and corners, and the abrasion work is completed through the collision and extrusion of the edges and corners with the material. Generally speaking, the more abrasive teeth 213 are arranged, the better the abrasive effect. However, a distance should be set between each abrasive tooth 213 so that the material can contact the edges and corners inside the abrasive tooth 213 and will not get stuck, and the material will not be stuck in the gap between two abrasive teeth 213. If the material is stuck in the gap between two abrasive teeth 213, the subsequent material will be squeezed down by the stuck material, so that the subsequent material cannot contact the edges and corners of the abrasive teeth 213, and the material accumulates more in the abrasive cavity 12, resulting in a reduction in abrasive efficiency. Therefore, a spacing distance should be set so that the material cannot get stuck.

[0031] Please refer to Figure 1 , the abrasive tooth 213 is a rectangular block and is provided with a first abrasive tooth 214 and a second abrasive tooth 215, and the first abrasive tooth 214 and the second abrasive tooth 215 are the two edges and corners at the abrasive end of the abrasive tooth 213. The material entering the abrasive cavity 12 is abraded by its first abrasive tooth 214 and second abrasive tooth 215. The abrasive cavity 12 is provided with a top plate 121 and a bottom plate; the top plate 121 and the bottom plate are respectively installed at the position where the first support portion is provided. A complete circle is formed between the top plate 121 and the bottom plate. Moreover, the top plate 121 should also keep the material in an abrasive state and ensure that the material will not splash out of the abrasive cavity 12. The top plate 121 and the bottom plate are combined to form the abrasive cavity 12; the bottom plate of the abrasive cavity 12 is set as a filter plate 122; filter holes 123 are arranged at uniform intervals on the filter plate 122. The filter holes 123 are arranged at all positions on the filter plate 122. The filter plate 122 is an arc-shaped plate. The side and the ground of the arc-shaped plate of the filter plate 122 can both discharge materials and filter. And the material will also be squeezed between the filter holes 123, which can also help the material accumulated in the filter holes 123 to be discharged. It can also help the material that does not reach the discharge particle size to be circularly abraded to reach the discharge particle size. The discharge particle size should be less than or equal to the aperture size of the filter holes 123.

[0032] See also Figure 1 and Figure 4 , the frames on both sides of the rotor 21 are provided with a first bearing seat 31 and a second bearing seat 32; the two ends of the rotor 21 are respectively provided in the first bearing seat 31 and the second bearing seat 32; the rotor 21 rotates based on the first bearing seat 31 and the second bearing seat 32. The first bearing seat 31 and the second bearing seat 32 are respectively provided with bearings, and the two ends of the rotor 21 are fixedly connected to the bearings of the first bearing seat 31 and the second bearing seat 32, and rotate based on them. The movement of the grinding teeth can be driven by the rotation of the rotor 21 to perform grinding. Through the setting of the bearing seat and the bearing, the smoothness of its rotation is guaranteed, and it can also perform stable grinding work.

The mounting holes 216 are provided at both ends of the abrasive tooth 213 to facilitate the replacement of both ends. Both ends of the abrasive tooth 213 are provided with edges and corners. When one end is worn and no longer sharp during abrasion, it can be disassembled and replaced with the other end for installation, and the previous mounting end is used as the current abrasive end for abrasion. Both ends of the abrasive tooth 213 can be used as an abrasive end or a mounting end respectively. When installing it, it is placed in a preset position, and the mounting rod 218 passes through each mounting hole 216 and the connecting hole 217 until the last one. The entry end of the mounting rod 218 is fixed by a locking nut 219. The locking nut 219 is a slotted and closed locking nut, and an anti-loosening rod is arranged on it. The anti-loosening rod passes through at least two slotted and closed ends of the locking nut for locking.

[0034] See also Figure 1 At least four abrasive teeth 213 are arranged on one circle of the separation plate 211. A plurality of abrasive teeth 213 are arranged on one circle of the separation plate 211 at uniform angles. Generally, four, five, or six abrasive teeth 213 are all acceptable, but not too many. If too many abrasive teeth 213 are arranged, the gaps between the abrasive teeth 213 will become smaller. As the gaps become smaller, the possibility of material accumulation will increase.

[0035] Preferably, the feeding chamber 11 communicates with the top plate 121 through a feeding port 124. Baffles 220 are arranged on the top plate 121 at uniform angular intervals, and the baffles 220 cover the inner wall of the top of the abrasive chamber 12. When the material splashes, it will collide with the top position, causing wear. In order to enable the material to circulate and protect the top plate 121, the baffles 220 are provided for protection. The material directly enters the abrasive chamber 12 through the feeding port 124 provided at the top of the feeding chamber 11.

[0036] Please refer to Figure 3 , the power assembly includes a driving motor 41, and a driving wheel 42 is connected to the output shaft of the driving motor 41.
