Background
Chlorinated polyethylene particles may contain moisture during the production process which, if not removed, may affect the final properties of the product. The water content of the granules can be reduced to a certain level (such as below 1% or below 0.3%) by dehydration and drying to meet the product performance requirements.
The existing dehydration drying device is mainly divided into centrifugal dehydration and fluidized bed dehydration, for the centrifugal dehydration, since the centrifugal machine throws chlorinated polyethylene particles to the outer edge of a tray in a pile through centrifugal force, if the density of the chlorinated polyethylene particles piled up at the moment is too large, the air circulation among the particles is not smooth, so that the heat transfer and the evaporation of moisture are influenced, the drying speed is further slowed down, and chemical reactions such as thermal decomposition or crosslinking and the like can be generated on the chlorinated polyethylene particles due to the fact that the chlorinated polyethylene particles are excessively heated, and the property of the chlorinated polyethylene particles is further changed.
However, when the fluidized bed is used for dehydrating the chlorinated polyethylene particles, the distribution and the flowing state of the chlorinated polyethylene particles in the drying chamber are uneven, so that the penetrability of air flow and the heat transfer efficiency are affected, and finally, the drying effect is inconsistent, and the product quality is affected. And the fluidized bed drying process requires precise control of various parameters such as inlet air temperature, wind velocity, bed height, particle residence time, etc. Small variations in these parameters can have a significant impact on the drying effect and thus can be difficult to operate.
And the stirring mode that adopts among the current drying device is mostly mechanical stirring, adopts stirring roller or stirring rake to carry out mechanical stirring to the material promptly, but to the chlorinated polyethylene granule of heat sensitivity, too high temperature and mechanical friction all probably cause harmful effect to its quality.

S2, starting a semi-attenuation centrifugal mechanism 12 after the first arc plate 9 and the second arc plate 10 are assembled, wherein the semi-attenuation centrifugal mechanism 12 drives the drying supporting plate 8 to perform reciprocating alternate acceleration and deceleration movement when being started;
s3, the overturning mechanism 13 sprays air to the direction of the drying supporting plate 8 through the spraying cylinder 14 so that chlorinated polyethylene particles can be fully overturned in the drying process;
and S4, after the drying is finished, the operator pulls the second arc plate 10 along the long side direction of the material guiding plate 7, and then the dehydrated chlorinated polyethylene particles are taken out from the drying supporting plate 8.
The theory of operation of this device is, and this device is when the operation, and operating personnel pulls second arc board 10 along the long limit direction of drawing flitch 7 earlier, puts into stoving layer board 8 with moist chlorinated polyethylene granule afterwards, then with first arc board 9 and second arc board 10 start motor 15 after the equipment is accomplished.
When the output end of the motor 15 rotates forwards and reversely, the power gear 20 drives the second belt pulley 25 to rotate through the first belt pulley 24, the second belt pulley 25 drives the speed increasing gear 27 to rotate through the driving gear 26, the speed increasing gear 27 drives the driving gear ring 29 to rotate through the transfer gear 28, the driving gear ring 29 drives the drying supporting plate 8 fixedly connected with the driving gear ring 29 to rotate, and chlorinated polyethylene particles at the upper end of the drying supporting plate 8 are centrifugally dehydrated in the rotating process. When the output end of the motor 15 is reversed, the second gear 17 drives the sliding gear 18 to move along the limiting arc groove 23 in a direction away from the power gear 20, the attaching gear 19 is separated from the power gear 20, and the power gear 20 is slowly slowed down. The drying pallet 8 is slowly lowered and the centrifugal force to which the chlorinated polyethylene particles on the drying pallet 8 are subjected is reduced.
When the output end of the motor 15 rotates positively, that is, when the corresponding laminating gear 19 is meshed with the power gear 20, the inner ring and the outer ring of the ratchet wheel 35 rotate relatively, the second gear 17 cannot drive the assembly gear 33 to rotate through the ratchet wheel 35, and when the output end of the motor 15 rotates reversely, that is, the corresponding laminating gear 19 is not meshed with the power gear 20, the inner ring and the outer ring of the ratchet wheel 35 rotate synchronously, the second gear 17 drives the assembly gear 33 to rotate through the ratchet wheel 35, and the assembly gear 33 drives the assembly gear ring 34 meshed with the assembly gear 33 to rotate. When the assembly gear ring 34 rotates, the air spraying cylinder 14 sprays air to the direction of the drying supporting plate 8 under the action of the reciprocating gear 39, so that chlorinated polyethylene particles can be fully turned over in the drying process.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention.
