[0024] As Figures 1-3 shown, a screening device for a fluidized granulator includes a support plate 101; a servo motor 102 is fixedly connected to the upper end of the support plate 101; a connecting rod 103 is fixedly connected to the output end of the servo motor 102; a first gear 104 is fixedly connected to the end of the connecting rod 103 away from the servo motor 102; a support block 105 is fixedly connected to the upper end of the support plate 101; a rotating cylinder 106 is arranged inside the support block 105; a gear disc 107 is fixedly connected to the outer side of the rotating cylinder 106; the gear disc 107 is meshed with the first gear 104; a first filter cylinder 108 and a second filter cylinder 109 are fixedly connected to the inside of the rotating cylinder 106; the second filter cylinder 109 is located inside the first filter cylinder 108; a particle inlet pipe 110 is arranged outside the support plate 101; one end of the particle inlet pipe 110 close to the rotating cylinder 106 penetrates the rotating cylinder 106; during operation, the servo motor 102 is started; the connecting rod 103 is driven to rotate by the output end of the servo motor 102; further, the connecting rod 103 drives the gear disc 107 to rotate through the first gear 104, so that the gear disc 107 drives the rotating cylinder 106, the first filter cylinder 108, and the second filter cylinder 109 to rotate, and then the granulator particles are introduced into the inside of the second filter cylinder 109 through the particle inlet pipe 110, and then the medium-sized granulator particles and the smaller granulator particles are separated into the inside of the first filter cylinder 108 by the rotation of the second filter cylinder 109, while the larger granulator particles are separated from the end of the second filter cylinder 109 away from the servo motor 102 by centrifugal force. At this time, by the rotation of the first filter cylinder 108, the smaller granulator particles are separated into the inside of the rotating cylinder 106, while the medium-sized granulator particles are separated from the end of the first filter cylinder 108 away from the servo motor 102 by centrifugal force, and the smaller particles are collected from the end of the rotating cylinder 106 away from the servo motor 102. This step significantly improves the classification efficiency of the granulator particles. After starting, the device finely classifies the particles of the granulator according to size, thereby improving the purity of the particles in each particle size range and greatly improving the convenience of subsequent processing and the controllability of product quality.

[0025] As Figures 1-4As shown, a first collection box 201 is provided at one end of the support block 105 away from the servo motor 102; the first collection box 201 is rotatably connected to the rotating cylinder 106 and internally interconnected; a second collection box 202 is fixedly connected to one end of the first collection box 201 away from the servo motor 102; the second collection box 202 is rotatably connected to the first filter cylinder 108 and internally interconnected; a third collection box 203 is fixedly connected to one end of the second collection box 202 away from the servo motor 102; the third collection box 203 is rotatably connected to the second filter cylinder 109 and internally interconnected; multiple threaded blocks 204 are fixedly connected to the outer side of the first collection box 201; a first bolt 205 is threadedly connected to the inner side of the threaded block 204; the first bolt 205 is threadedly connected to the support block 105; during operation, through the threaded connection between the first bolt 205, the threaded block 204, and the support block 105, the first collection box 201 is made to fit with the support block 105. Through the internal interconnection between the third collection box 203 and the second filter cylinder 109, larger particles separated by the second filter cylinder 109 are collected through the third collection box 203. At the same time, through the internal interconnection between the second collection box 202 and the first filter cylinder 108, medium-sized particles separated inside the first filter cylinder 108 are collected through the second collection box 202. Also, through the internal interconnection between the rotating cylinder 106 and the first collection box 201, smaller particles inside the rotating cylinder 106 are collected through the first collection box 201. In this step, through the third collection box 203, the second collection box 202, and the first collection box 201, the collection of particles of different sizes is achieved. Larger particles separated by the second filter cylinder 109 are collected through the third collection box 203, medium-sized particles separated by the first filter cylinder 108 are collected through the second collection box 202, and smaller particles in the rotating cylinder 106 are collected by the first collection box 201, thereby improving the particle collection efficiency and providing great convenience for subsequent processing or application.

[0026] As Figure 1 shown, a protective frame 301 is provided at the upper end of the support plate 101 and outside the servo motor 102 and the gear disk 107; the outer side of the protective frame 301 is fixedly connected to the support block 105 and the support plate 101 respectively; a connection frame 302 is provided at one end of the protective frame 301 away from the first collection box 201; four end corners of the connection frame 302 are threadedly connected with second bolts 303; the second bolts 303 are threadedly connected to the protective frame 301; during operation, rotate the second bolts 303, and thus the connection frame 302 is threadedly connected to the protective frame 301 through the second bolts 303; in this step, through the protective frame 301, the servo motor 102 and the gear disk 107 are reduced from being exposed in the working place, thereby improving the safety in the working environment.

[0027] AsFigure 2 As shown, a wear-resistant disc 401 is provided between the particle feed pipe 110 and the rotating cylinder 106; the inner side of the wear-resistant disc 401 is fixedly connected to the particle feed pipe 110; the outer side of the wear-resistant disc 401 is rotatably connected to the rotating cylinder 106; in this step, when the rotating cylinder 106 rotates, through the wear-resistant disc 401, the separation of the particles of the granulator from the end far from the first collection box 201 is reduced.

[0028] As Figure 1 As shown, a cooling fan 501 is fixedly connected to the inner side of the connection frame 302; during operation, the cooling fan 501 dissipates heat from the servo motor 102, thereby increasing the service life of the servo motor 102.

[0029] As Figures 1-3 As shown, first support legs 601 are symmetrically and fixedly connected to the lower end of the support plate 101 close to the servo motor 102; second support legs 602 are symmetrically and fixedly connected to the lower end of the support plate 101 close to the first collection box 201; fixed blocks 603 are fixedly connected to the lower ends of the first support legs 601 and the second support legs 602; anchor bolts 604 are threadedly connected to the four end corners of the fixed blocks 603; during operation, through the anchor bolts 604, the first support legs 601 and the second support legs 602 are fixed to the ground, and at the same time, since the second support legs 602 are shorter than the first support legs 601, the device is inclined with respect to the ground. In this step, by fixing the first support legs 601 and the second support legs 602 to the ground, the device is made more stable, and at the same time, by inclining the device with respect to the ground, the separation efficiency of the device is improved.

[0030] As Figure 5 As shown, a ball 701 is rotatably connected to the inner side of the support block 105; in this step, the wear of the support block 105 is reduced through the ball 701, thereby increasing the service life of the support block 105.

[0031] Working principle: When working, start the servo motor 102; drive the connecting rod 103 to rotate through the output end of the servo motor 102; then the connecting rod 103 drives the gear disc 107 to rotate through the first gear 104, so that the gear disc 107 drives the rotating cylinder 106, the first filter cylinder 108, and the second filter cylinder 109 to rotate. Then, introduce the granulator particles into the inner side of the second filter cylinder 109 through the particle feeding pipe 110. Then, through the rotation of the second filter cylinder 109, the medium-sized granulator particles and the smaller granulator particles are separated to the inner side of the first filter cylinder 108, while the larger granulator particles are separated from the end of the second filter cylinder 109 far away from the servo motor 102 by centrifugal force. At this time, through the rotation of the first filter cylinder 108, the smaller granulator particles are separated to the inner side of the rotating cylinder 106, while the medium-sized granulator particles are separated from the end of the first filter cylinder 108 far away from the servo motor 102 by centrifugal force, and the smaller particles are collected from the end of the rotating cylinder 106 far away from the servo motor 102. This step significantly improves the classification efficiency of the granulator particles. After starting, the device finely classifies the particles of the granulator by size, thereby improving the purity of the particles in each particle size range and greatly improving the convenience of subsequent processing and the controllability of product quality. When working, through the threaded connection between the first bolt 205, the threaded block 204, and the support block 105, the first collection box 201 is made to fit with the support block 105. Through the third collection box 203 and the inside of the second filter cylinder 109 being interconnected, the larger particles separated by the second filter cylinder 109 are collected through the third collection box 203. At the same time, through the second collection box 202 and the inside of the first filter cylinder 108 being interconnected, the medium-sized particles separated inside the first filter cylinder 108 are collected through the second collection box 202. At the same time, through the rotating cylinder 106 and the inside of the first collection box 201 being interconnected, the smaller particles inside the rotating cylinder 106 are collected through the first collection box 201. This step realizes the collection of particles of different sizes through the third collection box 203, the second collection box 202, and the first collection box 201. The larger particles separated by the second filter cylinder 109 are collected through the third collection box 203, the medium-sized particles separated by the first filter cylinder 108 are collected through the second collection box 202, and the smaller particles in the rotating cylinder 106 are collected by the first collection box 201, thus improving the particle collection efficiency and providing great convenience for subsequent processing or application. When working, rotate the second bolt 303, and then the connecting frame 302 and the protective frame 301 are threadedly connected through the second bolt 303;In this step, the protective frame 301 is used to reduce the exposure of the servo motor 102 and the gear disk 107 in the workplace, thereby improving the safety in the working environment. When the rotating cylinder 106 rotates, the anti-wear disk 401 is used to reduce the separation of the granulator particles from the end far away from the first collection box 201. During operation, the servo motor 102 is cooled by the cooling fan 501, thereby increasing the service life of the servo motor 102. During operation, the first support leg 601 and the second support leg 602 are fixed to the ground through the anchor bolts 604. At the same time, since the second support leg 602 is shorter than the first support leg 601, the device is inclined with respect to the ground. In this step, the first support leg 601 and the second support leg 602 are fixed to the ground, thereby making the device more stable. At the same time, due to the inclination of the device with respect to the ground, the separation efficiency of the device is improved. The wear of the support block 105 is reduced by the ball 701, thereby increasing the service life of the support block 105.;
