Description

Technical Field

[0001] The invention belongs to the technical field of vibrating drum screens, in particular to a sorting vibrating drum screen. Background Art

[0002] The sorting vibrating drum screen is a device that uses a cylindrical screen body to screen materials. The working part of the sorting vibrating drum screen is cylindrical, and the entire screen rotates around the axis of the cylinder. The axis is generally installed at a small inclination angle. The material is fed from one end of the cylinder. Under the action of vibration and gravity, fine-grade materials pass through the sieve holes on the cylindrical working surface, and coarse-grained materials are discharged from the other end of the cylinder.

[0003] Chinese invention patent CN116135338A relates to the field of screening technology and discloses a drum screen comprising a drum (7), a fine material collecting cover (5) surrounding the outer periphery of the drum (7), and a cleaning mechanism (6) radially movably mounted on the fine material collecting cover (5); the drum screen system has low screening efficiency and poor screening effect.

[0004] Chinese invention patent CN110813699A discloses a multi-stage drum screen for mining, which is characterized by comprising a base and several screening mechanisms, wherein the screening mechanisms include a drum screen, a drive mechanism, and an anti-blocking mechanism. The drive mechanism drives the drum screen to rotate, and all the drum screens are rotated and connected in sequence from the inside to the outside. The drum screen is difficult to operate and has low screening accuracy.

[0005] When the above-mentioned drum screen rotates and screens the raw materials, impurities in the raw materials are easily attached to the inner wall of the drum screen and the inner wall of the protective shell, thereby affecting the subsequent feeding stability and unblocking of the raw materials.

[0006] And when the amount of finished products inside the guide box is too much, it means that the feeding rate of the raw materials inside the drum screen is too fast, which will cause the finished products inside the guide box to be blocked and affect the normal feeding of subsequent raw materials.

[0007] At the same time, when the amount of finished products inside the guide box is too small, it means that the screen holes inside the drum screen or the inside of the protective shell are blocked, causing the raw materials inside the drum screen to be unable to be discharged stably, which in turn causes the raw materials to be unable to be fully and effectively vibrated and screened.

[0008] After the drum screen completes screening of the raw materials, a large amount of dust and impurities tend to adhere to the inside of the screen holes and the inner wall of the protective shell. If they cannot be thoroughly and effectively cleared and cleaned, the subsequent original vibration screening will be affected. Summary of the Invention

A plurality of horizontal plates 103 are evenly provided on the inner wall of the fixing frame 101, and the side walls of two adjacent horizontal plates 103 match the side walls of the lower hopper 401. The horizontal plates 103 connect and fix the lower hopper 401. A controller is provided on one side of the fixing frame 101, and the controller electrically controls each electrical component.

[0044] The driving assembly 2 includes two transmission shafts 204, and a plurality of rolling wheels 206 are evenly provided on the outer surface of the transmission shaft 204. The transmission shaft 204 rotates and drives the plurality of rolling wheels 206 to rotate. A workbench 203 is provided on one side of the fixed frame 101, and a reducer 202 is provided on the top of the workbench 203. The reducer 202 plays a role of deceleration and steering. The input end of the reducer 202 is provided with a driving motor 201, and the output end of the reducer 202 is fixedly connected to one end of the transmission shaft 204. The driving motor 201 starts and drives the transmission shaft 204 to rotate through the reducer 202. A plurality of connecting frames 207 are evenly provided on the top of the fixed frame 101, and a bearing seat 205 is provided on the top of the connecting frame 207. The inner wall of the bearing seat 205 is transmission-connected to the outer surface of the transmission shaft 204, and the bearing seat 205 provides rotational support for the transmission shaft 204.

[0045] The screening assembly 3 includes multiple drum screens 301, which rotate and screen the raw materials inside. A protective shell 306 is provided on the outer surface of the drum screen 301, which wraps and protects the internal drum screen 301. At the same time, the protective shell 306 can also gather and recycle the finished products produced when the drum screen 301 rotates and screens, further improving the recycling efficiency and recycling effect.

[0046] The bottom of the protective shell 306 is fixedly connected to the top of the lower hopper 401, and the inner bottom of the protective shell 306 is connected to the interior of the lower hopper 401. Therefore, the finished product screened by the drum screen 301 enters the lower hopper 401 along the inner wall of the protective shell 306 for subsequent vibration recovery. The distance between the inner wall of the protective shell 306 and the outer surface of the drum screen 301 matches. A feed hopper 303 is provided at one end of the drum screen 301, and raw materials are poured into the interior of the drum screen 301 along the feed hopper 303. A discharge hopper 304 is provided at the other end of the drum screen 301. Both the feed hopper 303 and the discharge hopper 304 are connected to the interior of the drum screen 301. Impurities generated after the raw materials are screened by the drum screen 301 are directly discharged along the discharge hopper 304, and the protective shell 306 is rotatably connected to the feed hopper 303 and the discharge hopper 304 through bearings. When the feed hopper 303 and the discharge hopper 304 drive the drum screen 301 to rotate, they will not drive the protective shell 306 to rotate.

[0047] The inside of the drum screen 301 is evenly provided with a plurality of sieve holes 302. The diameter of the sieve holes 302 gradually increases from the end of the feed hopper 303 to the end of the miscellaneous hopper 304. The sieve holes 302 rotate and screen according to the volume of the raw material. The outer surfaces of the feed hopper 303 and the miscellaneous hopper 304 are provided with sliding rings 311. The outer surface of the sliding ring 311 is frictionally and slidably connected with the outer surface of the rolling wheel 206. The rolling wheel 206 rotates and drives the feed hopper 303 and the miscellaneous hopper 304 to rotate through friction with the sliding ring 311. 3 and the discharge hopper 304 drive the drum screen 301 to rotate. The outer surface of the drum screen 301 and the inner walls of the feed hopper 303 and the discharge hopper 304 are symmetrically provided with multiple splicing rings 305. Two adjacent splicing rings 305 are fixedly connected by threads. The splicing rings 305 further improve the connection and fixing effect of the feed hopper 303, the discharge hopper 304 and the drum screen 301. When the feed hopper 303 and the discharge hopper 304 rotate, they can also synchronously drive the drum screen 301 to rotate and stir and screen the raw materials inside.

[0048] The inside of the drum screen 301 is evenly provided with a plurality of snap-in holes 313, and the inner wall of the snap-in holes 313 is provided with a stirring plate 307. When the drum screen 301 rotates, the stirring plate 307 is synchronously driven to rotate, and the stirring plate 307 blocks and stirs the raw materials inside the drum screen 301, further improving the mixing and screening effect of the raw materials. The inside of the stirring plate 307 is provided with an inner hole 308, and the inner wall of the inner hole 308 is sealed and slidably connected with a movable plate 310. The movable plate 310 can move inside the inner hole 308 and adjust the length of the stirring plate 307 accordingly, thereby adjusting the mixing and screening effect of the raw materials inside the drum screen 301. The end of the stirring plate 307 away from the central axis of the drum screen 301 is provided with a There is an elastic plate 312, which matches the collision head 418. The side wall of the elastic plate 312 is evenly provided with multiple connecting springs 309. The other end of the connecting spring 309 is fixedly connected to one end of the movable plate 310. The setting of the connecting spring 309 ensures the elastic reset performance of the movable plate 310. Therefore, when the drum screen 301 drives the stirring plate 307 to rotate, the bottom of the elastic plate 312 will continuously collide with the top of the collision head 418 and generate a vibration force. The vibration force drives the movable plate 310 to move up and down inside the inner hole 308 inside the stirring plate 307 through the connecting spring 309, further improving the vibration screening effect of the raw materials inside the drum screen 301.

[0049] The recycling component 4 includes multiple discharge hoppers 401, which vibrate and discharge finished products of different sizes. An inner cavity 402 is opened inside the discharge hopper 401, and the inner cavity 402 is used for gas circulation. The inner sealing sliding connection of the inner cavity 402 is connected with a sealing plate 403, which moves up and down inside the inner cavity 402 and drives the gas inside the inner cavity 402 to circulate. A plurality of moving rods 404 are evenly arranged on the top of the sealing plate 403, and a collision head 418 is provided on the top of the moving rod 404. Therefore, when the sealing plate 403 moves up and down, the moving rod 404 is synchronously driven to move up and down, and the moving rod 404 drives the collision head 418 to move up and down. A vent 405 is provided inside the moving rod 404, and the vent 405 is used for gas circulation. A plurality of vertical rods 410 are evenly arranged on the bottom of the sealing plate 403, and the sealing plate 403 moves up and down, synchronously driving the vertical rod 410 below to move up and down.

[0050] A one-way exhaust valve 406 is provided inside the air vent 405. The one-way exhaust valve 406 is used to discharge the gas inside the inner cavity 402 in one direction. The exhaust direction of the one-way exhaust valve 406 is along the end of the inner cavity 402 to the inner wall end of the protective shell 306. Therefore, the gas discharged from the air vent 405 can not only clean the inside of the protective shell 306 with wind power, but also block the wind power of the finished product inside the protective shell 306, further realizing the stable discharge of the finished product. The inner wall of the lower hopper 401 is evenly provided with a plurality of side holes 407 above the sealing plate 403. A one-way air inlet valve 408 is provided inside the side hole 407. The air inlet of the one-way air inlet valve 408 The direction is from the outside to the inside of the inner cavity 402. When the sealing plate 403 moves downward in the inner cavity 402, the volume inside the inner cavity 402 increases and the pressure decreases, and the external gas can enter the inner cavity 402 along the one-way air inlet valve 408 inside the side hole 407. Then, when the sealing plate 403 moves upward in the inner cavity 402, the volume inside the inner cavity 402 decreases and the pressure increases, and the gas inside the inner cavity 402 can be discharged along the one-way exhaust valve 406 inside the vent 405 to the inner wall of the protective shell 306 and block the wind force on the finished product, further improving the finished product inside the protective shell 306 to continuously and stably flow and discharge to the lower hopper 401.

[0051] A plurality of return springs 409 are evenly arranged at the inner bottom of the inner cavity 402, and the top of the return spring 409 is fixedly connected to the bottom of the sealing plate 403. The return spring 409 is located on the outer surface of the vertical rod 410. The setting of the return spring 409 further improves the elastic return performance of the sealing plate 403. Therefore, when the movable rod 404 drives the collision head 418 to move upward, the top of the collision head 418 collides with the bottom of the elastic plate 312, and the elastic plate 312 drives the movable plate 310 to move upward through a plurality of connecting springs 309. The movable plate 310 improves the stirring and mixing effect of the raw materials inside the drum screen 301.

[0052] A plurality of limiting holes 417 are evenly provided on the upper part of the lower hopper 401. The inner wall of the limiting hole 417 is sealed and slidably connected to the outer surface of the moving rod 404. The limiting hole 417 seals and limits the moving rod 404 to ensure that the gas inside the inner cavity 402 can flow along the inside of the vent 405. A plurality of matching holes 419 are evenly provided on the lower part of the lower hopper 401. The inner wall of the matching hole 419 matches the outer surface of the vertical rod 410. The setting of the matching hole 419 ensures the up and down movement effect of the vertical rod 410, and the diameter value of the matching hole 419 is larger than the diameter value of the vertical rod 410. The diameter value of the reset spring 409 is larger than the diameter value of the matching hole 419. Therefore, the setting of the reset spring 409 improves the movement stability of the vertical rod 410.

[0053] The bottom of the lower hopper 401 is provided with a guide box 411, and the inner wall of the guide box 411 is provided with a cross frame 415. The tops of the guide box 411 and the cross frame 415 are fixedly connected to the bottoms of multiple vertical rods 410. When the guide box 411 moves up and down, the vertical rods 410 are driven up and down by the cross frame 415. An inclined chute 416 is opened inside the guide box 411, and the top of the inclined chute 416 corresponds to the bottom output end of the lower hopper 401. The finished products inside the lower hopper 401 slide directly out along the inclined chute 416. The top of the guide box 411 is provided with a U-shaped frame 412, and the top of the U-shaped frame 412 is evenly provided with multiple mounting seats 413. The top of the mounting seat 413 is provided with a vibration motor 414. When the vibration motor 414 works, it drives the guide box 411 to vibrate up and down through the mounting seat 413 and the U-shaped frame 412, thereby realizing the vibration unloading of the finished products inside the inclined chute 416, realizing the vibration drum screening and sorting process of the raw materials, and ensuring the screening quality.

[0054] When the drum screen 301 rotates and screens the raw materials, dust and impurities in the raw materials are easily attached to the inner wall of the drum screen 301 and blocked inside the sieve holes 302, thereby affecting the subsequent feeding stability and unblocking of the raw materials; and when the amount of finished products inside the inclined chute 416 is too much, it means that the feeding rate of the raw materials inside the drum screen 301 or the protective shell 306 is too fast, which will cause the finished products inside the inclined chute 416 to be blocked and affect the normal feeding of subsequent raw materials; at the same time, when the amount of finished products inside the inclined chute 416 is too little, it means that the sieve holes 302 inside the drum screen 301 are blocked and the raw materials inside the drum screen 301 cannot be fed stably, which will cause the raw materials to be unable to be fully and effectively vibrated and screened; and when the drum screen 301 completes the screening of the raw materials, a large amount of dust and impurities are easily attached to the inside of the sieve holes 302 and the inner wall of the protective shell 306. If they cannot be thoroughly and effectively unblocked and cleaned, the subsequent original vibration screening will be affected.

[0055] In order to solve the above problems, when the sorting vibrating drum screen is actually used, the controller first controls the drive motor 201 to start and drives the transmission shaft 204 to rotate inside multiple bearing seats 205 through the reducer 202. The transmission shaft 204 rotates and drives multiple rolling wheels 206 to rotate. The rolling wheels 206 and the sliding rings 311 rub against each other and drive the feed hopper 303 and the discharge hopper 304 to rotate. The feed hopper 303 and the discharge hopper 304 synchronously drive the drum screen 301 to rotate inside the protective shell 306, thereby achieving the subsequent rotation screening effect of the raw materials.

[0056] The raw materials are then poured into the drum screen 301 along the feed hopper 303. The continuous rotation of the drum screen 301 drives the raw materials to rotate. At the same time, the raw materials contact and collide with the stirring plate 307 and the movable plate 310 and are fully stirred and mixed. The finished products of the same size fall down along the sieve holes 302 at the corresponding positions to the inner wall of the protective shell 306. The raw materials continue to slide down and enter the inclined chute 416 inside the guide box 411 along the lower hopper 401 for guidance and discharge, thereby further improving the flow recovery effect of raw materials of different sizes.

[0057] At the same time, the controller controls the vibration motor 414 to start the initial power and continuously generate vibration force, which is transmitted to the end of the guide box 411 with the help of the mounting base 413 and the U-shaped frame 412 and drives the guide box 411 to vibrate continuously. With the help of this vibration force, the finished products inside the inclined chute 416 can be driven to vibrate up and down continuously, effectively avoiding the accumulation of finished products inside the inclined chute 416 and affecting the screening and unloading stability of the subsequent drum screen 301.

[0058] When the guide box 411 continuously vibrates up and down, it synchronously drives multiple vertical rods 410 to move up and down. The vertical rod 410 drives the moving rod 404 to move up and down through the sealing plate 403. The moving rod 404 drives the collision head 418 on the top to move up and down. The collision head 418 continuously reciprocates with the outer surface of the drum screen 301, and cooperates with the continuous rotation of the drum screen 301 to improve the fluidity of the raw materials inside the drum screen 301 and the unblocking of the finished products inside the sieve hole 302, ensuring that the drum screen 301 rotates and screens continuously and stably, and the straightness of the moving rod 404 The diameter is larger than the diameter of the sieve hole 302, thereby avoiding obstruction to the rotation of the drum screen 301 when the moving rod 404 moves up and down, and when the collision head 418 and the outer surface of the drum screen 301 are squeezed and contacted with each other, the moving rod 404 can no longer drive the collision head 418 to move upward, and the drum screen 301 drives multiple sieve holes 302 to rotate when it rotates. At this time, the collision head 418 collides with the end of the stirring plate 307 inside the drum screen 301, further realizing mutual vibration friction, thereby improving the crushing, mixing and screening effect of the raw materials inside the drum screen 301.

[0059] At the same time, when the moving rod 404 drives the collision head 418 to move up and down, the collision distance between the top of the collision head 418 and the bottom of the elastic plate 312 is constantly changing, and in conjunction with the drum screen 301 to drive the rotation of the stirring plate 307, the elastic plate 312 drives the movable plate 310 to move back and forth inside the inner hole 308 through the connecting spring 309, further improving the reciprocating collision and crushing effect of the movable plate 310 on the raw materials inside the drum screen 301, ensuring that the raw materials inside the drum screen 301 can be continuously and stably crushed and screened.

[0060] And when the sealing plate 403 continuously moves up and down inside the inner cavity 402, the extrusion pressure exerted by the sealing plate 403 on the gas inside the inner cavity 402 continuously changes, and the external gas continuously enters the inner cavity 402 along the one-way air inlet valve 408 inside the side hole 407, and the gas inside the inner cavity 402 continuously discharges to the inside of the protective shell 306 along the one-way exhaust valve 406 inside the vent 405, further realizing the pulse wind force blocking of the finished product inside the protective shell 306, ensuring the fluidity and stability of the finished product continuously sliding down from the inside of the protective shell 306 to the inside of the discharge hopper 401, and effectively avoiding the accumulation of finished products inside the protective shell 306 and affecting the discharge efficiency.

[0061] When the amount of finished products inside a certain inclined chute 416 increases, it means that the raw materials inside the drum screen 301 have been screened, and the amount of finished products accumulated inside the protective shell 306 is too much. Therefore, it is necessary to reduce its unloading rate accordingly to ensure that the finished products inside the inclined chute 416 are first vibrated and discharged, and then the finished products inside the protective shell 306 are subjected to subsequent unloading processes. Therefore, due to the increase in the amount of finished products inside the inclined chute 416, the weight inside the guide box 411 increases accordingly and drives multiple vertical rods 410 to move downward through the horizontal frame 415. The distance between the top of the guide box 411 and the bottom of the discharge hopper 401 increases, and more finished products can be loaded inside the inclined chute 416. In conjunction with the vibration motor 414, the guide box 411 is driven to vibrate continuously, further ensuring that the finished products inside the inclined chute 416 can slide down and be discharged more efficiently and continuously, thereby improving the unloading stability and continuity.

[0062] When the guide box 411 drives the vertical rod 410 to move downward, the vertical rod 410 drives the sealing plate 403 to move downward inside the inner cavity 402, and the sealing plate 403 simultaneously drives the moving rod 404 and the top collision head 418 to move downward. Therefore, the vibration force generated by the vibration motor 414 drives the moving rod 404 and the top collision head 418 to move downward in the same manner. The moving rod 404 drives the top collision head 418 upward and reduces the contact time with the outer surface of the drum screen 301, and the collision head 418 has a great impact on the inner surface of the drum screen 301. The vibration discharge efficiency applied by the raw materials is reduced, and at the same time, the extrusion force applied by the collision head 418 to the elastic plate 312 is reduced. The elastic plate 312 drives the movable plate 310 to move up and down inside the inner hole 308 through the connecting spring 309 to reduce the distance. The collision and crushing force applied by the movable plate 310 to the raw materials inside the drum screen 301 is reduced, thereby reducing the speed at which the raw materials inside the drum screen 301 enter the protective shell 306 downward along the screen hole 302, thereby avoiding the accumulation of finished products inside the protective shell 306 and affecting the subsequent normal screening and discharge.

[0063] At the same time, the moving rod 404 drives the sealing plate 403 to increase its up and down vibration amplitude inside the inner cavity 402, and the amount of external gas entering the inner cavity 402 along the one-way air inlet valve 408 inside the side hole 407 increases. Then, the sealing plate 403 moves upward to squeeze the gas inside the inner cavity 402, and the amount of gas discharged along the one-way exhaust valve 406 inside the vent 405 increases. With the help of this discharged gas, the wind blocking effect of the finished product inside the protective shell 306 is further improved, and the discharge rate of the finished product inside the protective shell 306 along the discharge hopper 401 into the inclined chute 416 is reduced, thereby ensuring that the finished product inside the inclined chute 416 is continuously vibrated and discharged, avoiding excessive accumulation of finished products inside the inclined chute 416 and ultimately affecting the normal screening quality of the drum screen 301 and the sliding discharge stability of the inclined chute 416.

[0064] When the amount of finished products in the inclined chute 416 decreases, it indicates that the raw materials in the drum screen 301 are accumulated or the screen holes 302 are blocked, resulting in low screening efficiency. In this way, it is necessary to fully crush and mix the raw materials in the drum screen 301 and clear the blockage of the screen holes 302. Therefore, due to the decrease in the amount of finished products in the inclined chute 416, the weight of the guide box 411 decreases and the downward force exerted on the multiple vertical rods 410 by the horizontal frame 415 is reduced. Under the elastic force of the return spring 409, the sealing plate 403 is driven to move upward along the inner cavity 402. The distance increased, the sealing plate 403 drives the top collision head 418 As the upward moving distance increases, the vibration motor 414 continuously works and drives the moving rod 404 and the top collision head 418 to move up and down, the collision force between the collision head 418 and the drum screen 301 increases, further improving the vibration and clearing effect of the collision head 418 on the drum screen 301. At the same time, due to the increase in the extrusion contact time between the collision head 418 and the drum screen 301, and the rotation of the drum screen 301, the extrusion force between the collision head 418 and the outer wall of the drum screen 301 and the stirring plate 307 increases. Under the action of the vibration, the stirring plate 307 further improves the mixing, stirring and crushing effect of the raw materials inside the drum screen 301.

[0065] And since the extrusion contact area between the collision head 418 and the outer surface of the drum screen 301 increases, the scraping and cleaning area of the collision head 418 for the raw materials blocked inside the sieve hole 302 is increased, further improving the dredging and fluidity inside the sieve hole 302, and when the drum screen 301 drives the stirring plate 307 to rotate, the extrusion force between the top of the collision head 418 and the bottom of the elastic plate 312 increases, and the elastic plate 312 drives the movable plate 310 to move closer to the central axis of the drum screen 301 inside the inner hole 308 through multiple connecting springs 309. The distance increases, which correspondingly improves the pushing and crushing effect of the movable plate 310 on the raw materials inside the drum screen 301, ensuring that the raw materials can be continuously and stably screened and discharged.

[0066] And since the movement range of the sealing plate 403 inside the inner cavity 402 is reduced, the amount of external gas entering the inner cavity 402 along the one-way air inlet valve 408 inside the side hole 407 is reduced, and the amount of gas inside the inner cavity 402 discharged to the inside of the protective shell 306 along the one-way exhaust valve 406 inside the air vent 405 is reduced. The reverse thrust exerted by the gas on the finished product inside the protective shell 306 is reduced, and the finished product inside the protective shell 306 can continue to fall efficiently along the lower hopper 401 to the inside of the inclined chute 416, thereby ensuring the discharge speed and discharge stability of the finished product inside the inclined chute 416, avoiding blockage inside the drum screen 301 and reducing the recovery efficiency of the finished product.

[0067] After the vibration screening of the raw materials inside the drum screen 301 is completed, the controller controls the vibration motor 414 to start at the maximum power, and no finished products are discharged from the inclined chute 416. At this time, under the elastic force of the return spring 409, the sealing plate 403 is driven to move upward along the inner cavity 402 to the maximum distance. At this time, the maximum vibration force generated by the vibration motor 414 is synchronously transmitted to the end of the sealing plate 403 through the guide box 411 and the vertical rod 410. The sealing plate 403 drives the moving rod 404 to move up and down to the maximum amplitude. The moving rod 404 drives the collision head 418 to apply the collision force to the outer surface of the drum screen 301 to reach the maximum value and further improves the vibration scraping effect on the dust and impurities attached to the outer surface of the drum screen 301.

[0068] At the same time, the extrusion contact area between the collision head 418 and the outer surface of the drum screen 301 reaches a maximum value, and the scraping and cleaning effect applied by the collision head 418 to the raw materials blocked inside the screen hole 302 reaches a maximum value, and the unblocking effect of the screen hole 302 is further improved. In this process, the extrusion force applied by the collision head 418 to the elastic plate 312 reaches a maximum value, and the elastic plate 312 drives the movable plate 310 to move along the inner hole 308 to the maximum distance close to the central axis of the drum screen 301 through the connecting spring 309. The movable plate 310 and the inner wall of the inner hole 308 are fully scraped and cleaned, and the cleaning effect on the outer surface of the movable plate 310 is correspondingly improved.

[0069] When the vibration motor 414 drives the sealing plate 403 to move up and down inside the inner cavity 402 to the maximum extent, the amount of external gas entering the inner cavity 402 along the one-way air inlet valve 408 inside the side hole 407 reaches the maximum, and the amount of gas inside the inner cavity 402 discharged to the inside of the protective shell 306 along the one-way exhaust valve 406 inside the air vent 405 reaches the maximum. With the help of this gas, the inner wall of the protective shell 306 can be fully and effectively cleaned by wind, so that the dust and impurities on the inner wall of the protective shell 306 can be fully separated, thereby avoiding the dust and impurities from affecting the subsequent vibration screening of raw materials.

[0070] After the drum screen 301 and the inner wall of the protective shell 306 are cleaned, the raw materials are continuously poured into the drum screen 301 through the feed hopper 303 , and the above process is continuously repeated to perform a vibration screening process on the raw materials.

[0071] The sorting vibrating drum screen has high vibration screening efficiency and good vibration screening effect, meets the actual vibration screening needs of raw materials, is simple to operate, safe and stable, has strong adaptability to material discharge, high stability, strong controllability and good dredging performance; in the process of vibrating screening of raw materials, the collision dredging and unblocking of the drum screen 301 and the reverse gas push for material discharge of the finished products inside the protective shell 306 are simultaneously realized, and the movable plate 310 is correspondingly driven to move up and down and improve the collision and crushing effect of the raw materials inside the drum screen 301; and when the amount of finished products inside the inclined chute 416 increases, the sealing plate 403 drives the moving rod 404 and the collision head 418 on the top to move downward, and the discharge amount of the internal gas of the inner cavity 402 along the vent 405 increases and the gas reverse thrust on the raw materials inside the protective shell 306 is correspondingly improved, It is ensured that the finished products inside the protective shell 306 continuously and stably flow along the discharge hopper 401 into the inclined chute 416 for flow discharge; at the same time, when the amount of finished products inside the inclined chute 416 decreases, the sealing plate 403 drives the moving rod 404 and the collision head 418 at the top to move upward, and the collision and clearing effect of the collision head 418 on the drum screen 301 is enhanced. At the same time, the movable plate 310 moves outward along the inner hole 308. The distance and the corresponding collision and crushing effect on the raw materials inside the drum screen 301 are improved; and after the vibration screening is completed, the vibration clearing of the drum screen 301 by the collision head 418 and the reverse gas thrust of the vent 405 are increased, thereby achieving the clearing effect of the drum screen 301 and the protective shell 306, effectively avoiding the impact on the vibration screening effect of subsequent raw materials.
