[0002] Modified plastics refer to plastic products that are processed and modified by filling, blending, reinforcing and other methods on the basis of general plastics and engineering plastics to improve the flame retardancy, strength, impact resistance, toughness and other properties. The modified plastic parts can not only achieve the strength properties of some steel materials, but also have a series of advantages such as light weight, rich colors, easy molding, etc. Therefore, the trend of "replacing steel with plastics" has emerged in many industries. Modified plastics are generally granular after production, and these granular modified plastic particles need to be dried before storage and use.

However, the prior art still has defects:

[0004] The plastic particle drying device used in the prior art stirs and dries the plastic particles inside the drum by drum-type stirring. However, the water vapor evaporated from the inside of the plastic particles will liquefy when cooled, and after turning into water droplets, it is easy to adhere to the surface of the device, which is easy to cause rust and damage to the machine over time.

A heating mesh plate 6 for heating the gas ejected from the jet hole 5 is provided on the upper side of the inside of the movable chamber 2. There is a certain distance between the heating mesh plate 6 and the top of the inside of the movable chamber 2 to avoid directly heating the space inside the drying barrel 1 for holding modified plastic particles.

[0021] In order to enable the movable block 3 to move to both sides inside the movable chamber 2, the utility model is provided with a reciprocating screw rod 7 inside the movable chamber 2, and the two ends of the reciprocating screw rod 7 are respectively connected to the two sides inside the movable chamber 2 for rotation, and the reciprocating screw rod 7 is driven by a first motor 17 installed on one side of the outside of the drying barrel 1, and a mounting hole 8 is opened on one side of the movable block 3, and the movable block 3 is sleeved on the outside of the reciprocating screw rod 7 through the mounting hole 8, and a protrusion 9 is installed at the top of the inside of the mounting hole 8, and the protrusion 9 is stuck in the thread groove of the reciprocating screw rod 7 As the reciprocating screw 7 rotates, the thread groove pushes the protrusion 9. After the movable block 3 moves to one side of the inside of the movable chamber 2, the protrusion 9 just reaches the intersection of the two thread grooves of the reciprocating screw 7. As the reciprocating screw 7 continues to rotate, the movable block 3 moves in the opposite direction driven by the protrusion 9, and thus reciprocates on both sides inside the movable chamber 2, and blows the plastic particles inside the drying barrel 1 back and forth through a plurality of vents 12 opened at the bottom end of the drying barrel 1. There is a rotating shaft 10 inside the drying barrel 1.

The bottom end of the stirring shovel 11 is an arc, which can just fit together with the bottom end of the interior of the drying barrel 1. There is a baffle on the other side. The modified plastic particles in the interior of the drying barrel 1 are stirred by the rotation of the stirring shovel 11 to ensure the uniformity of the drying of the plastic particles. Feed ports 13 are provided on both sides of the upper end of the exterior of the drying barrel 1. Cover plates 14 are provided inside the two feed ports 13. A heating fence 15 is provided at the top of the interior of the drying barrel 1 to prevent the water vapor brought out by the air flow after heating from being cooled and re-liquefied.

After the air inlet pipe 21 is connected to the air pump, the air pump is started, and the first motor 17 and the second motor 18 respectively start to drive the reciprocating screw 7 and the rotating shaft 10 to rotate. The stirring shovel 11 connected to the lower end of the rotating shaft 10 starts to stir the modified plastic particles inside the drying barrel 1. The movable block inside the movable chamber 2 moves back and forth to both sides under the drive of the reciprocating screw 7. The plastic particles are gradually blown, which can also further ensure the uniformity of drying. The water vapor evaporated from the heated plastic particles is driven upward by the air flow, and is heated again by the heating fence 15 before contacting the top plate at the top of the drying barrel 1, and is sprayed out from the air outlet 16. After the plastic particles are dried, the valve of the discharge pipe 19 is opened to discharge the modified plastic particles.
