[0002] In order to achieve resource recycling and alleviate environmental pressure, plastic products are usually recycled and reprocessed. In order to facilitate subsequent processing, the recycled plastics are usually crushed into recycled plastic particles and then sent to the next process. Recycled plastics usually contain high moisture content and need to be thoroughly dried before they can be sent to the next process for further processing.

Most of the plastic particles inside are difficult to disperse to the outside, affecting the drying uniformity. In addition, the screen drum rolling method is not convenient for unloading after dehydration is completed. Therefore, a recycled plastic dehydration device is proposed to address the above problems.

A positioning rod 66 is fixedly connected to a side of the shielding cover 64 near the connecting block 65. The other end of the positioning rod 66 is rotatably connected to the connecting block 65. When working, one end of the drying pipe 2 The end is connected to the external hot air blower, one side of the water removal tank 1 is fixedly connected to the first motor, the output end of the first motor passes through the water removal tank 1 and is fixedly connected to one end of the drying pipe 2, one side of the water removal tank 1 is fixedly connected to the second motor, the output end of the second motor passes through the adjusting groove 61 and is fixedly connected to one end of the double-headed threaded rod 62, through the setting of the shielding mechanism 6, in conjunction with the drying pipe 2 and the partition plate 3, it is convenient to separate and dewater the plastic particles, avoid the docking of a large number of plastic particles to affect the dewatering efficiency, ensure the dewatering efficiency, and facilitate the discharge of the plastic particles after dewatering, that is, the plastic to be dewatered The particles are put into the dewatering tank 1 through the discharge port opened on the top of the dewatering tank 1 and fall on the drying tube 2. At the same time, the first motor is started to drive the drying tube 2 to rotate, so that the plastic particles are evenly dropped between the multiple annular equidistantly distributed partition plates 3. With the help of two relatively arranged shielding covers 64, the plastic particles are continuously turned along with the drying tube 2. At the same time, hot air is introduced into the drying tube 2 through an external hot air blower, and is sprayed out through the drying hole 4 and the auxiliary hole 5 to dry the continuously rolling plastic particles, thereby ensuring the drying efficiency of the plastic particles. After the drying is completed, the external second motor can be started to drive the double-headed threaded rod 62 Rotate, the double-headed threaded rod 62 rotates to drive the two transmission blocks 63 on it to move away from each other, and cooperate with the positioning rod 66 to drive the two shielding covers 64 to rotate and expand, so that the shielding of the plastic particles is lifted, and the plastic particles after dehydration automatically fall down and are discharged through the discharge port opened at the bottom of the dehydration tank 1, and can continue to be driven by the first motor to rotate the drying tube 2 until all the plastic particles between all the partition plates 3 are discharged, and then the second motor can be started again to drive the double-headed threaded rod 62 to reverse, and the two shielding covers 64 close to each other to shield multiple partition plates 3, and the rising step can be repeated to dehydrate the plastic particles again.

[0035] Working principle: the plastic particles to be dehydrated are put into the dehydration box 1 through the discharge port opened on the top of the dehydration box 1 and fall on the drying tube 2. At the same time, the first motor is started to drive the drying tube 2 to rotate, so that the plastic particles are evenly dropped between a plurality of annular equidistantly distributed partition plates 3. The two oppositely arranged shielding covers 64 are used to make the plastic particles continue to flip along with the drying tube 2. At the same time, hot air is introduced into the drying tube 2 through an external hot air blower, and sprayed out through the drying hole 4 and the auxiliary hole 5 to dry the continuously rolling plastic particles, thereby ensuring the drying efficiency of the plastic particles. After the drying is completed, the external second motor can be started to drive the double-headed threaded rod 62 to rotate. The rotation of the double-headed threaded rod 62 drives the two transmission blocks 63 on it to move away from each other, and cooperates with the positioning rod 66 to drive the two shielding covers 64 to rotate and expand, thereby removing the shielding of the plastic particles and dehydrating them. The plastic particles fall automatically and are discharged through the discharge port at the bottom of the water removal tank 1, and can continue to be driven by the first motor to rotate the drying tube 2 until all the plastic particles between all the partition plates 3 are discharged, and then the second motor can be started again to drive the double-headed threaded rod 62 to reverse, and the two shielding covers 64 are closed to each other to shield multiple partition plates 3, and the rising step can be repeated to remove the water from the plastic particles again. While the drying tube 2 rotates, it drives the pressing ring 10 to rotate, and the pressing ring 10 drives multiple annular equidistant pressing blocks 11 to rotate, and the pressing block 11 intermittently applies pressure to the abutment block 9 and pushes the transmission ring 7 to slide, and then the transmission ring 7 is reset under the pressure of the spring 8 and drives the hammer block 12 to reset, so that the hammer block 12 intermittently hammers on the shielding cover 64, so that the shielding cover 64 and the drying tube 2 are intermittently subjected to vibration force.
