DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-4 A centrifugal particle dehydrator includes a processing machine cover and a dehydration component and a loading and unloading component assembled in the processing machine cover.

[0030] The dehydration assembly includes a dehydration tray 21 and an assembly cover 22. The dehydration tray 21 and the assembly cover 22 are fixedly combined and rotatably installed in the processing machine cover. The inner wall of the dehydration tray 21 is fixedly connected to a material blocking strip 211. A drainage gap 11 is provided between the dehydration tray 21 and the processing machine cover. A drainage hole connected to the drainage gap 11 is opened on the dehydration tray 21.

[0031] The loading and unloading components include a transmission cylinder 31, a mounting shaft 32, and a spiral conveying blade 33. The transmission cylinder 31 is fixedly installed in the processing machine cover and arranged at the axis center of the dehydration tray 21 and the assembly cover 22. The transmission cylinder 31 is rotationally connected to the dehydration tray 21 and the assembly cover 22. The top of the transmission cylinder 31 extends to the top of the processing machine cover and is fixedly connected to a feeding interface 311. The bottom of the transmission cylinder 31 is provided with an inlet and outlet port 312 arranged at the bottom of the dehydration tray 21. The mounting shaft 32 is rotatably installed at the axis center of the transmission cylinder 31. The spiral conveying blade 33 is fixed to the mounting shaft 32 and fits with the inner wall of the transmission cylinder 31.

[0032] The setting of the processing machine cover can ensure that the dehydration component is stably installed in it in a relatively rotating manner, and ensure that the dehydration component operates at high speed and stably to achieve efficient dehydration of the plastic particles. At the same time, it can also ensure that the transmission cylinder 31 in the loading and unloading components is fixedly installed on the processing machine cover, so that the transmission cylinder 31 extends to the dehydration tray 21, realizing the loading and unloading operations of the plastic particles.

[0033] In the dehydration assembly, the dehydration tray 21 is used to receive the plastic particles to be dehydrated, and the setting of the assembly cover 22 can ensure that the high-speed running plastic particles are gathered in the dehydration tray 21 to prevent them from spilling into the processing machine cover. When the dehydration tray 21 runs at high speed, the material blocking strips 211 thereon can drive the plastic particles therein to run at high speed, and the water attached to the plastic particles is thrown outward under the action of centrifugal force and leaks into the outer drainage gap 11 along the leakage holes on the dehydration tray 21. The released water can be discharged from the drainage gap 11, thereby completing the dehydration of the plastic particles.

[0034] When loading the plastic particles, the plastic particles to be dehydrated are input from the feeding interface 311 at the top of the transmission cylinder 31. Under the operation of the mounting shaft 32 and the spiral conveying blades 33, the plastic particles can be vertically transported downward along the transmission cylinder 31 to the dehydration tray 21. After the dehydration of the plastic particles is completed, the plastic particles gather at the bottom of the dehydration tray 21 and enter the bottom of the transmission cylinder 31 from the inlet and outlet ports 312. When the mounting shaft 32 and the spiral conveying blades 33 operate in the opposite direction, the plastic particles can be transported upward from the bottom of the dehydration tray 21 along the transmission cylinder 31 and finally output from the feeding interface 311.

[0035] In order to ensure that the dehydration tray 21 and the assembly cover 22 can be stably installed in the processing shell in a relatively rotating manner, to ensure that the transmission cylinder 31 is fixedly installed in the processing machine cover, and to ensure that the removed water can be effectively discharged from the processing machine cover, the following technical solutions are provided.

[0039] In order to ensure that the processing machine cover can be stably supported on the horizontal ground, and thus ensure the stable operation of the internal dehydration components and loading and unloading components, the following technical solutions are provided.

[0040] Multiple groups of evenly distributed support legs 134 are fixedly connected to the outer wall of the installation shell 13 , and each group of support legs 134 is fixedly connected via a reinforcement ring 135 .

[0041] The top of the support leg 134 is fixed to the outer wall of the mounting shell 13 by welding, and the bottom of the support leg 134 can be stably supported by the horizontal ground. The reinforcement ring 135 is welded to each support leg 134 to ensure the structural stability of each support leg 134 and ensure that each support leg 134 stably supports the processing machine cover.

[0042] In order to ensure that the dehydration tray 21 and the assembly cover 22 can achieve high-speed operation, the following technical solutions are provided.
