The processing component 3 also includes a feed box 1 309 rotatably installed on the inner wall of the granulator 201. The feed box 1 309 is connected to the feed hopper 301 through a conveying pipe 2 308. The raw materials enter the feed box 1 309 through the conveying pipe 2 308. A feed box 2 311 is provided at the lower end of the feed box 1 309. The feed box 1 309 is communicated with the feed box 2 311.

After the raw material enters the feed box 1 309, it enters the feed box 2 311, and the feed box 2 311 discharges the material into the granulator 201 through the discharge port 312. When discharging, the one-way valve of the storage box 313 is opened, and the auxiliary material in the storage box 313 enters the discharge port 312 and is mixed with the raw material and enters the granulator 201 synchronously. At the same time, the feed box 1 309 is driven to rotate along the axis of the granulator 201 in the granulator 201 to improve the uniformity of the raw material falling and avoid the raw material from piling up in one position.

Three groups of material blocking plates 317 are slidably arranged on the material unloading rack 316, and a material unloading trough 318 is arranged on the material blocking plate 317. The material blocking plate 317 blocks the bottom of the stirring disk 310. In the granulation state, the material blocking plate 317 is close to the material unloading rack 316 to prevent the raw materials and particles from being discharged through the bottom of the stirring disk 310.When there are more raw materials entering the granulator 201, the electric cylinder 319 is driven to work, and the electric cylinder 319 drives the reversing plate 314 to move. The reversing plate 314 moves toward the direction close to the stirring disk 310, thereby improving the holding capacity of the stirring disk 310 for raw materials and improving the granulation efficiency. When there are fewer raw materials, the electric cylinder 319 is driven to work, and the electric cylinder 319 drives the reversing plate 314 to move away from the stirring disk 310, thereby reducing energy consumption and improving the granulation effect. After the granulation is completed, the baffle plate 317 is driven away from the unloading rack 316, and the baffle plate 317 opens the bottom of the stirring disk 310, and the particles enter the discharge box 202 through the unloading chute 318 for screening. A cleaning hole 320 is set on the side of the stirring disk 310, and the raw materials that fall into the inside of the stirring disk 310 are cleaned through the cleaning hole 320.

[0035] Working principle: during operation, the raw material is placed on the belt 107, and the belt 107 is started to work. The belt 107 drives the raw material into the feed hopper 301, and at the same time drives the cam 109 to rotate. The cam 109 drives the pressing plate 110 to slide back and forth on the support frame 108, and the pressing plate 110 drives the rebound column 111 to insert into the raw material. When there is a hard object in the raw material, the hard object pushes the rebound column 111, and the sensor set in the rebound column 111 receives a signal, proving that there is a hard object in the raw material. Since there are multiple groups of rebound columns 111, the position of the hard object is determined by the signal of the sensor, and then the push rack 115 is driven to move, and the push rack 115 drives the push plate 116 to move on the lifting frame 113, driving the push plate 116 to slide in the push rack 115, and the push plate 116 is driven to slide in the push rack 115. 6 is inserted into the raw material and contacts the side of the hard object, driving the push rack 115 to move, and the push rack 115 drives the push plate 116 to push the hard object out of the raw material, completing the processing of the hard object in the raw material, and the belt 107 drives the magnetic roller 114 to rotate while transporting the raw material. The magnetic roller 114 flattens the raw material when it rotates, and at the same time, the magnetic roller 114 adsorbs the magnetic material in the raw material to clean the raw material. In the process of transporting the raw material, the adsorption box 103 is started intermittently, and the adsorption box 103 performs sampling adsorption on the raw material. After the raw material enters the adsorption box 103, the humidity of the raw material is detected by the humidity detector of the adsorption box 103, and the working efficiency of the drying head 302 is adjusted in real time according to the detection result. The raw material adsorbed by the adsorption box 103 is discharged into the feed hopper 301 through the conveying pipe 104.

[0036] After the raw materials enter the feed hopper 301, they first pass through the sieve plate 2 303, which screens the raw materials to avoid caking and foreign matter, and synchronously drives the cam 304 to rotate. The cam 304 drives the vibration plate 305 to knock on the feed hopper 301 to increase the falling speed of the raw materials, and drives the drying head 302 to work. The drying head 302 dries the fallen raw materials, and adjusts the working efficiency of the drying head 302 according to the humidity detection result of the raw materials by the conveying component 1, drives the rotating disk 2 307 to rotate, and after the rotating disk 2 307 is opened, the raw materials enter the feed box 1 309 through the conveying pipe 2 308. After the raw materials enter the feed box 1 309, they enter The raw materials are fed into the feed box 311, and the feed box 311 discharges the materials into the granulator 201 through the discharge port 312. When discharging the materials, the one-way valve of the storage box 313 is opened, and the auxiliary materials in the storage box 313 enter the discharge port 312 to be mixed with the raw materials and enter the granulator 201 synchronously. At the same time, the feed box 309 is driven to rotate along the axis of the granulator 201 in the granulator 201, and the mixed raw materials fall on the reversing plate 314. The angle of the reversing plate 314 is adjusted according to the weight of the raw materials entering the granulator 201. After the adjustment is completed, the stirring disk 310 is driven to rotate in the granulator 201, and the spray head of the granulator 201 is driven to work to mix and granulate the raw materials.

[0037] After granulation is completed, the rotating disk 2 307 is driven to slide on the unloading frame 316, and the baffle plate 317 releases the blocking of the bottom of the stirring disk 310, and the rotating disk 1 209 is opened at the same time. At this time, the particles pass through the baffle plate 317 and the unloading chute 318 to enter the discharge box 202. After the particles pass through the granulator 201 and enter the discharge box 202, the two groups of cams 207 are driven to rotate, and the cams 207 drive the two groups of sieve plates 1 205 to shake. When the particles reach the first group of sieve plates 1 205, the larger particles remain on the sieve plate 1 205, and the smaller particles fall on the second group of sieve plates 1 205. The aperture on 5 is smaller than the required particle diameter. At this time, the particles smaller than the required particle diameter pass through the second group of sieve plates 205 and are discharged through the opening at the lower end of the discharge box 202. The particles left on the second group of sieve plates 205 are the required particles. When it is necessary to take out the particles on the sieve plates 205, the discharge port 204 is driven to move on the discharge box 202, and the discharge box 202 releases the blocking on the side of the discharge box 202, and drives the push plate 206 to slide in the discharge box 202. The push plate 206 pushes the particles on the sieve plate 205, completing the unloading of the particles, and placing the particles that meet the standards into the fluidized bed for drying.
