A screening box 3 connected to the inside of the drying box 1 is provided at the bottom of the drying box 1. The screening box 3 can screen the modified TPU particles, and a discharge port 31 is provided on the screening box 3. The qualified products after classification are discharged through the discharge port 31. The drying box 1 is provided with maintenance components, and the maintenance components include a placement port 15 and a maintenance plate 5.

The maintenance plate 5 is placed on the support plate 7, and a hot air blower 51 and an electric telescopic rod 52 are installed on the top of the maintenance plate 5. One end of the hot air blower 51 passes through the maintenance plate 5 and is connected to an air outlet 510. When the hot air blower 51 is working, it can blow hot air through the air outlet 510, thereby drying the modified TPU particles. One end of the electric telescopic rod 52 passes through the maintenance plate 5 and is connected to a flapping plate 520. When the dried agglomerated TPU particles are transported to the right, the electric telescopic rod 52 drives the flapping plate 520 to flap.

[0024] In this embodiment, preferably, a spring 92 is installed inside the placement port 15, and one end of the spring 92 is connected to a clamping plate 9 that can abut against the maintenance plate 5. The clamping plate 9 is a trapezoidal structure. When the maintenance plate 5 is placed on the support plate 7, the maintenance plate 5 first squeezes the trapezoidal clamping plate 9. After the trapezoidal clamping plate 9 is squeezed, the spring 92 is compressed. After the spring 92 is compressed, it resets, driving the trapezoidal clamping plate 9 to clamp on the maintenance plate 5, thereby reinforcing the maintenance plate 5 placed on the support plate 7, and the maintenance plate 5 can be pulled up and removed as needed to maintain the blocked air outlet duct 510 and the worn flapping plate 520, thereby improving the maintenance efficiency.

[0025] In this embodiment, preferably, a slide bar 91 is provided at the bottom of the splint 9, and a slide groove 71 for the slide bar 91 to slide is provided at the top of the support plate 7. When the splint 9 is squeezed and moved, the slide bar 91 is driven to slide in the slide groove 71, thereby increasing the stability of the splint 9 when moving.

[0026] In this embodiment, preferably, a motor 11 and a control panel 12 are installed on the front surface of the drying box 1, and the output shaft of the motor 11 extends to the interior of the drying box 1 and is connected to a dispersion member 110.

[0027] In this embodiment, preferably, a vibrating screening plate 6 is provided inside the support frame 2, and a screen 61 is provided on the vibrating screening plate 6. When the dispersed modified TPU particles fall onto the vibrating screening plate 6, the screen 61 screens the dispersed modified TPU particles, and the modified TPU particles that meet the product specifications fall downward and are discharged through the discharge port 31.

[0028] In this embodiment, preferably, a return pipe 41 and an inclined pipe 42 are provided on the screw conveyor 4, and the return pipe 41 is connected to the feed pipe 13, the inclined pipe 42 is connected to the screening box 3, and one end of the vibrating screening plate 6 extends to the inside of the inclined pipe 42. Some agglomerated modified TPU particles pass through the vibrating screening plate 6 to the left and enter the inclined pipe 42, and enter the screw conveyor 4 through the inclined pipe 42. The motor of the screw conveyor 4 drives the screw conveying shaft to operate, and the modified TPU particles are transported upward and returned to the drying box 1 through the return pipe 41 for further drying and dispersion.

[0029] Example 2

[0030] See also Figure 1-Figure 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that:

[0031] An electric push rod 8 is installed on the inner top of the drying box 1 by bolts, which realizes the stable installation of the electric push rod 8, and one end of the electric push rod 8 is connected to a rubber scraper plate 81. When the electric push rod 8 is working, it can drive the rubber scraper plate 81 to adjust up and down. A conveyor belt 14 is arranged inside the drying box 1, and the distance between the rubber scraper plate 81 and the conveyor belt 14 can be adjusted as needed. The agglomerated modified TPU particles are put into the drying box 1 through the feed hopper 130 and fall onto the conveyor belt 14. The conveyor belt 14 transports the agglomerated modified TPU particles to the right, and the modified TPU particles accumulated on the upper end of the conveyor belt 14 are scraped thin by the rubber scraper plate 81.

[0032] It should be noted that the specific structure and working principle of the rubber scraper plate 81, conveyor belt 14, hot air blower 51, disperser 110, vibrating screening plate 6, and screen 61 in this application have been disclosed in a TPU particle screening device with publication number CN220242083U.

[0033] The working principle and use process of the utility model are as follows: when in use, the agglomerated modified TPU particles are put into the drying box 1 through the feed hopper 130 and fall onto the conveyor belt 14. The conveyor belt 14 transports the agglomerated modified TPU particles to the right, and the modified TPU particles accumulated on the upper end of the conveyor belt 14 are scraped thin by the rubber scraper 81. During the transportation process, the hot air generated by the two hot air blowers 51 is blown out through the air outlet 510 to dry the agglomerated modified TPU particles. When the dried agglomerated modified TPU particles are transported to the right, the electric telescopic rod 52 drives the flapping plate 520 to flap, and the motor 11 drives the dispersion member 110 to disperse the agglomerated modified TPU particles. Rotate, and the agglomerated modified TPU particles after drying are dispersed by the rotating dispersing element 110. When the dispersed modified TPU particles fall to the vibrating screening plate 6, the screen 61 screens the dispersed modified TPU particles. The modified TPU particles that meet the product specifications fall downward and are discharged through the discharge port 31. Some agglomerated modified TPU particles pass through the vibrating screening plate 6 to the left and enter the inclined pipe 42, and enter the screw conveyor 4 through the inclined pipe 42. The motor of the screw conveyor 4 drives the screw conveying shaft to run, and the modified TPU particles are transported upward and returned to the drying box 1 through the return pipe 41 for further drying and dispersion.
