[0060] Workflow:

[0061] First, the raw materials to be pulverized are put into the pulverizer 2. Then, the pulverizer 2 pulverizes the raw materials into large-particle raw materials and small-particle raw materials. Both the large-particle raw materials and the small-particle raw materials will fall above the first filter member 4, which is located in the middle of the discharge channel. Then, the driving motor 68 drives the rotating frame 65 to rotate. The rotating frame 65 drives the first filter member 4 to rotate through the guide rod. As a result, the large-particle raw materials and the small-particle raw materials located in the middle of the discharge will be thrown outwards by the centrifugal force. Then, the discharge channel is composed of the discharge baffle 43 and the first filter member 4. The discharge baffle 43 is in a plate-like structure. Then, the large-particle and small-particle raw materials will impact on the discharge baffle 43. And because the discharge channel is spiral, the large-particle raw materials and the small-particle raw materials will be conveyed along the discharge channel under the action of the centrifugal force. The first filter area 411 on the first filter member 4 allows the small-particle raw materials to pass through the first filter area 411 and reach the discharge device. The discharge device is in a cylindrical structure, so as to collect the small-particle raw materials, realizing the discharge of the small-particle raw materials that do not meet the requirements of recycling and the raw materials with smaller particles close to powder.

[0062] The large-particle raw materials are conveyed to the baffle 42 along the discharge channel. Then, the large-particle raw materials are discharged outwards from the outlet 44 on the baffle 42 to the recycling device 3 under the action of the centrifugal force.

[0063] In some cases, when it is necessary to adjust the outlet 44 of the pulverizer 2, the outlet 44 of the pulverizer 2 changes from large to small. The driving device drives the conical block 69 to rotate. The conical block 69 drives the ventilation steel pipe 7 to rotate through the connecting rod 64. Then, the air outlet pipe 71 on the ventilation steel pipe 7 rotates, which will make the area of the second blocking part blocking the first filter area 411 become larger, so that the particles filtered by the first filter area 411 become smaller. Then, when it is necessary to obtain raw materials with a particle size of x after the pulverizer 2 pulverizes, the particle size that the first filter area 411 can filter is adjusted to be slightly smaller than x. Then, it can be ensured that the raw materials that meet the requirements are on the first filter member 4 and will not pass through the first filter area 411, so as to ensure that the raw materials that meet the requirements are discharged along the discharge channel to the recycling device 3, and the raw materials that do not meet the requirements pass through the first filter area 411 and the second filter area and reach the receiving device 5.

[0064] In some cases, when it is necessary to adjust the outlet 44 of the grinder 2, as the outlet 44 of the grinder 2 gradually increases from small to large, the driving device drives the conical block 69 to rotate. The conical block 69 drives the ventilation steel pipe 7 to rotate through the connecting rod 64. Then the air outlet pipe 71 on the ventilation steel pipe 7 rotates, which will reduce the area of the second blocking part blocking the first filter area 411, so that the particles filtered by the first filter area 411 become larger. Then, when the raw material with a particle size of y needs to be obtained after the grinder 2 crushes, the particle size that the first filter area 411 can filter is adjusted to be slightly smaller than y. Then it can be ensured that the raw materials that meet the requirements are located on the first filter element 4 and will not pass through the first filter area 411, so as to ensure that the raw materials that meet the requirements are discharged along the discharge channel into the recycling device 3, and the raw materials that do not meet the requirements pass through the first filter area 411 and the second filter area to reach the receiving device 5.

[0065] During the rotation of the rotating frame 65, the rotating frame 65 drives the first filter element 4 to rotate. The first universal ball 62 at the first filter element 4 will rotate together with the first filter element 4. Then the first universal ball 62 abuts against the second universal ball 63, which will cause the first universal ball 62 to move upward, so that the first filter element 4 moves upward. Then after the first universal ball 62 passes over the second universal ball 63, the first filter element 4 will move downward under its own gravity and the action of the elastic member 67. In this way, the first filter element 4 moves upward and downward reciprocally, so as to realize the vibration of the first filter element 4 during rotation.

[0066] Vibration can cause the raw materials on the first filter element 4 to be separated from the first filter element 4 under the action of vibration. Then, the raw materials that have not been in contact with the first filter element 4 will come into contact with the first filter element 4, and the raw materials that were previously in contact with the first filter element 4 will reach the upper part of the raw materials that have not been in contact with the first filter element 4. Thus, the position of the raw materials on the first filter element 4 is adjusted, making them vibrate continuously and change positions up and down, so as to avoid the phenomenon that large-particle raw materials block the first filter area 411 and small-particle raw materials cannot pass through the first filter area 411.

[0067] The first filter element 4 moves up and down, which will cause the first push rod 671, the second push rod 642 and the first push plate 643 to move up and down, and then the piston plate 645 will move up and down, so that the air in the air box 641 will be pressed into the vent pipe 646, and then the air will reach the vent steel pipe 7 through the vent pipe 646, and then reach the outlet pipe 71, so that the elastic cloth 72 will bulge outward. Since the elastic part is the second stop part, when the elastic cloth 72 bulges outward, it will inevitably contact the raw material at the first filter area 411, so that the raw material at the first filter area 411 will be pushed to flip, so that the raw material on the first filter element 4 can be better flipped up and down to a certain extent. In addition, the large particles of raw materials blocking the first filter area 411 can be displaced, so that they no longer block the first filter area 411. The discharge of small particles of raw materials is better guaranteed.

[0068] The limiting portion 712 is located in the first filter zone 411. The purpose of the flexible portion 713 is to achieve that when the second blocking portion partially blocks the first filter zone 411, the flexible portion 713 contacts the first filter element 4 and deforms, so as to better adapt to the shape of the first filter zone 411. The first filter element 4 is a plate, and the first filter zone 411 is a hole, which can better ensure that the elastic cloth 72 is flush with the upper end surface of the first filter element 4, thereby better ensuring the discharge of the raw material along the discharge channel and avoiding the raw material from being stuck in the first filter zone 411.

[0069] The circular hole on the limiting portion 712 and the elastic portion at the circular hole will move together with the elastic cloth 72 at the air outlet pipe 71. Then, when the elastic cloth 72 at the circular hole protrudes outward, the raw material in the first filter area 411 can be radially squeezed to a certain extent, so that the raw material that blocks the first filter area 411 and causes the first filter area 411 to be blocked can be pressurized to a certain extent, forced upward or downward, and then squeezed outward, thereby avoiding blockage of the first filter area 411.

[0070] When the crusher 2 performs crushing, the output motor drives the output shaft 243 to rotate, the output shaft 243 drives the rotating block 241 to rotate, and the rotating block 241 forms a crank-slider structure through the first transmission connecting rod 23 and the second transmission connecting rod 231, so that the first pressing part 221, the second pressing part 223 and the connecting cloth move away from and close to the first pressing plate 21. Sliders are arranged on the first pressing part 221, the second pressing part 223 and the connecting part 222, and chutes are formed in the outer shell. The sliders are slidably connected with the chutes and are used to guide the first pressing part 221, the second pressing part 223 and the connecting part 222. Thus, the operation of crushing the raw materials is realized. Since both the first pressing part 221 and the second pressing part 223 can approach the first pressing plate 21, crushing can be performed at multiple angles, increasing the crushing effect. By adjusting the position of the mounting plate 25 through the driving cylinder 26, the maximum distance between the second pressing part 223 and the first pressing plate 21 can be adjusted, so as to realize the adjustment of the discharging size.
