Since the screening shell 201 includes the screening plate 11 and the annular shell 12, when the rotating rod one 209 and the rotating rod two 2010 rotate, the annular shell 12 is driven to rotate, and the rotating rod one 209 and the rotating rod two 2010 drive the gear seven 2011 and the gear eight 2012 on them to rotate. Since the gear seven 2011 is meshed with the annular rack seven 2013 fixedly connected with the outer side wall of the screening plate 11, when the gear seven 2011 rotates, the annular rack seven 2013 rotates.

Since the auxiliary plate 208 is triangular, the black phosphorus powder moves to the inclined surface on the auxiliary plate 208 under the rotation of the auxiliary plate 208, and then moves to be crushed between the upper crushing roller 208 and the lower crushing roller 207. Thus, the qualified black phosphorus powder is screened under the rotation of the auxiliary plate 208 and falls into the collecting shell 203. The unqualified black phosphorus powder is crushed by the upper crushing roller 208 and the lower crushing roller 207. The particle size of the crushed black phosphorus powder is further reduced, which meets the requirements of subsequent processing on particle size.

During the crushing process, the extrusion force generated by the relative rotation of the upper crushing roller 208 and the lower crushing roller 207 can ensure that the black phosphorus powder is fully crushed. Moreover, since the auxiliary plate 208 continuously rotates, new black phosphorus powder is continuously transported between the upper crushing roller 208 and the lower crushing roller 207, so that the crushing work can be continuously and efficiently performed. The whole crushing and screening process of the present application is more smooth, the overall quality and recovery efficiency of the black phosphorus powder are improved, and high-quality raw material guarantee is provided for subsequent processing and use.

[0028] When the placing shell 309 rotates with the rotating disc 308, the placing shell 309 drives the gear ten 3013 to rotate, because a set of annular gear racks ten 3014 are respectively meshed with a set of gear tens 3013, and the annular gear racks ten 3014 are in a fixed state, so that when the gear ten 3013 rotates, the gear ten 3013 rotates through the annular gear rack ten 3014, thereby driving the placing shell 309 and the can body 3010 in it to rotate, and the rotation of the placing shell 309 and the can body 3010 further enhances the movement effect of the black phosphorus powder and the grinding balls in the can body 3010, on the basis of the can body 3010 revolving with the rotating seat 301 and rotating circumferentially with the rotating disc 308, the self-rotation makes the movement track of the black phosphorus powder and the grinding balls in the can body 3010 more complex and diverse, and the action of the centrifugal force, the friction force and the impact force is more comprehensive and in-depth, the black phosphorus powder particles can more thoroughly collide and rub with the grinding balls in the all-around and high-intensity movement, further improving the grinding efficiency, so that the particle size of the black phosphorus powder can faster and more uniformly reach 200 meshes, effectively improving the quality of the black phosphorus powder, providing higher-quality raw materials for subsequent processing and use, and because the sorting, screening and grinding of the present application are all completed by the single motor 106, the energy consumption and manufacturing cost of the equipment are reduced, the equipment area is reduced, the whole device is more compact and efficient, the design of the single motor 106 driving simplifies the transmission system, reduces the number of transmission components, reduces the probability of failure, improves the operation stability and reliability of the equipment, and moreover, the integrated design is convenient for operators to centrally control and monitor, can timely adjust the operation parameters of the equipment, ensures the smooth progress of the sorting, screening and grinding process, meets the requirements of environmental protection and energy saving.

[0029] In use, the pretreated waste is put into the feeding shell 104, so that the waste enters the sorting shell 103 through the feeding shell 104, at this time the motor 106 drives the rotating shaft 107 to rotate, the rotating rod 105 and the spiral blade 1010 are driven to rotate through the sprocket one 108 and the chain one 109, the spiral blade 1010 drives the waste to move forward when rotating, and in the moving process, the coarse particle shell moves to the outlet of the sorting shell 103 and falls to be collected, and the black phosphorus powder in the waste falls into the discharging shell 202 through the holes on the sorting shell 103, and then moves to the circular discharging plate 204 along the discharging shell 202, at this time the rotating shaft 107 synchronously drives the bevel gear four 206 to rotate, because the bevel gear three 205 is meshed with the bevel gear four 206, the bevel gear four 206 drives the bevel gear three 205 to rotate, thereby driving the circular discharging plate 204 to rotate, so that the black phosphorus powder constantly changes the discharging position under the rotation of the circular discharging plate 204, so that when the black phosphorus powder falls into the screening shell 201, it is uniformly distributed, avoiding the black phosphorus powder from accumulating on the screening shell 201, affecting the screening efficiency of the black phosphorus powder, improving the screening efficiency.

[0030] When the bevel gear four 206 rotates, the bevel gear four 206 drives the gear six 1012 to rotate, because the gear six 1012 and the gear five 1011 are meshed with each other, the gear six 1012 drives the gear five 1011 to rotate, thereby driving the rotating shell 32 to rotate, and the rotating direction of the rotating shell 32 is opposite to that of the helical blade 1010, the opposite rotating direction improves the separation effect of the black phosphorus powder in the waste material, and the separation efficiency and effect of the black phosphorus powder are further improved.

[0031] When the black phosphorus powder falls on the screening shell 201, the circular discharge plate 204 drives the fixed rod 207 to rotate when rotating, the fixed rod 207 drives a group of auxiliary plates 208 to rotate, because the auxiliary plates 208 are triangular and the outer wall bottom end and the inner wall bottom end of the screening shell 201 are in contact with each other, in the rotating process, the auxiliary plates 208 can stir and push the black phosphorus powder accumulated in the screening shell 201, prevent the black phosphorus powder from being locally accumulated too thick in the screening shell 201, affect the screening effect, make the black phosphorus powder more evenly distributed in the screening shell 201, ensure the efficient screening work, speed up the screening process of the black phosphorus powder, and further improve the overall work efficiency.

[0032] When the fixed rod 207 rotates, the lower crushing roller 207 and the upper crushing roller 208 are driven to rotate by the synchronous belt, and the lower crushing roller 207 and the upper crushing roller 208 drive the rotating rod one 209 and the rotating rod two 2010 to rotate. Since the screening shell 201 includes the screening plate 11 and the annular shell 12, the rotating rod one 209 and the rotating rod two 2010 drive the annular shell 12 to rotate when they rotate, and the rotating rod one 209 and the rotating rod two 2010 drive the gear seven 2011 and the gear eight 2012 on them to rotate. Since the gear seven 2011 and the annular gear rack seven 2013 fixedly connected to the outer side wall of the screening plate 11 are in meshing relationship, the gear seven 2011 rotates through the annular gear rack seven 2013, and the gear seven 2011 and the gear eight 2012 are in meshing relationship, so that the gear seven 2011 drives the gear eight 2012 to rotate, thereby driving the lower crushing roller 207 and the upper crushing roller 208 to rotate relatively through the rotating rod one 209 and the rotating rod two 2010, so that the rotation of the lower crushing roller 207 and the upper crushing roller 208 crushes the black phosphorus powder. Since the auxiliary plate 208 is triangular, the black phosphorus powder moves to the inclined surface on the auxiliary plate 208 under the rotation of the auxiliary plate 208, and then moves to be crushed between the upper crushing roller 208 and the lower crushing roller 207, so that the qualified black phosphorus powder is screened under the rotation of the auxiliary plate 208 and falls into the collecting shell 203, and the unqualified black phosphorus powder is crushed by the upper crushing roller 208 and the lower crushing roller 207. The particle size of the black phosphorus powder after crushing is further reduced, which meets the requirements of subsequent processing on particle size. Through the screening shell 201, the black phosphorus powder falls into the collecting shell 203, and the crushing process is carried out continuously and efficiently, so that the whole crushing and screening process of the application is more smooth, the overall quality and recovery efficiency of the black phosphorus powder are improved, and high-quality raw material guarantee is provided for subsequent processing and use.

[0033] The screened black phosphorus powder falls into the collecting shell 203 and is collected. At this time, the staff puts the screened black phosphorus powder into the tank body 3010 according to a certain proportion, and then puts appropriate grinding balls into the tank body 3010. At this time, the protective shell 303 is opened. The protective shell 303 is prior art and will not be described again. Then the placing shell 309 is opened, the tank body 3010 is placed into the placing shell 309, and then the placing shell 309 is closed.

[0034] The rotation of the rotating shaft 107 drives the circular rod 304 to rotate through the sprocket wheel two 306, the chain two 307, the circular rod 304 drives the bevel gear two 305 to rotate, because the bevel gear one 302 and the bevel gear two 305 are meshed with each other, the bevel gear two 305 drives the bevel gear one 302 and the rotating seat 301 to rotate, when the rotating seat 301 rotates, it drives the rotating disc 308 and the placing shell 309 to rotate, the tank body 3010 in the placing shell 309 rotates with it, the tank body 3010 is used to contain the black phosphorus powder and the grinding ball with suitable particle size after being screened by the screening unit 200, during the rotation of the tank body 3010, the black phosphorus powder and the grinding ball in the tank body 3010 continuously roll and collide under the action of centrifugal force, realizing the grinding of the black phosphorus powder, with the continuous rotation of the tank body 3010, the black phosphorus powder and the grinding ball rub and impact each other violently, the particle size of the black phosphorus powder gradually decreases, after a period of grinding, the particle size of the black phosphorus powder can reach 200 meshes, meeting the requirements of subsequent processing and use, after grinding, the placing shell 309 is opened, the tank body 3010 is opened, and the ground black phosphorus powder is taken out.

[0035] When the rotating seat 301 rotates, it drives the rotating disc 308 to rotate, the rotating disc 308 drives the gear nine 3011 on it to rotate, because the ring gear nine 3012 and the group of gear nine 3011 are meshed with each other, and the ring gear nine 3012 is in a fixed state, when the gear nine 3011 rotates, it rotates through the ring gear nine 3012, thereby driving the rotating disc 308 to rotate, so that the rotating disc 308 drives the placing shell 309 and the tank body 3010 to rotate with it, so that the tank body 3010 not only rotates with the rotating seat 301, but also rotates with the rotating disc 308, enhancing the movement intensity of the black phosphorus powder and the grinding ball in the tank body 3010, while the tank body 3010 revolves with the rotating seat 301, it also revolves in a circle due to the rotation of the rotating disc 308, so that the black phosphorus powder and the grinding ball in the tank body 3010 are subjected to more intense centrifugal force, friction and impact force, the black phosphorus powder particles can collide and rub with the grinding ball more quickly and fully in a multi-dimensional and high-intensity movement environment, further accelerating the process of reducing the particle size of the black phosphorus powder, and this mode effectively avoids the local accumulation or uneven grinding of the black phosphorus powder in the tank body 3010, ensuring that the black phosphorus powder can be uniformly and carefully ground.

[0036] When the placing shell 309 rotates with the rotating disc 308, the placing shell 309 drives the gear wheel 3013 to rotate, because a set of annular gear racks 3014 are respectively meshed with a set of gear wheels 3013, and the annular gear racks 3014 are in a fixed state, so that when the gear wheel 3013 rotates, the annular gear rack 3014 rotates, thereby driving the placing shell 309 and the can body 3010 in it to rotate, and the rotation of the placing shell 309 and the can body 3010 further enhances the movement effect of the black phosphorus powder and the grinding balls in the can body 3010. On the basis of the revolution of the can body 3010 with the rotating seat 301 and the revolution of the rotating disc 308, the rotation makes the movement track of the black phosphorus powder and the grinding balls in the can body 3010 more complex and diverse, and the action of the centrifugal force, the friction force and the impact force is more comprehensive and in-depth. In the all-around and high-intensity movement of the black phosphorus powder particles, the black phosphorus powder particles can more thoroughly collide and rub with the grinding balls, further improving the grinding efficiency, so that the particle size of the black phosphorus powder can more quickly and uniformly reach 200 meshes, effectively improving the quality of the black phosphorus powder, and providing higher-quality raw materials for subsequent processing and use.

[0037] Because the sorting, screening and grinding of the present application are all completed by the single motor 106, the energy consumption and manufacturing cost of the equipment are reduced, the equipment floor space is reduced, the whole device is more compact and efficient, the design of the single motor 106 driving simplifies the transmission system, reduces the number of transmission components, reduces the probability of failure, improves the operation stability and reliability of the equipment, and moreover, the integrated design is convenient for the operator to centrally control and monitor, can timely adjust the operation parameters of the equipment, ensures the smooth progress of the sorting, screening and grinding process, meets the requirements of environmental protection and energy saving.
