With the assistance of the stirring assembly 3, the plastic fragments added to the rinsing chamber 1 are rinsed and processed. The drive assembly 6 is responsible for operating the stirring assembly 3. The system provides power. After rinsing, PET has a higher density than water, so the PET bottle fragments will gradually sink to the bottom of the rinsing chamber 1.

[0030] Example two Based on the rinsing equipment for PET bottle recycling plastic processing in the above example one, in the use process, with the plastic pieces on the water surface being dispersed, the grooves 304 on the stirring blade 302 become defects, so that the stirring blade 302 has gaps when pressing the plastic pieces into the water, and then the efficiency of rinsing the plastic pieces into the water is reduced, at the same time, the stirring of the water surface by the stirring blade 302 is too large when rotating, which is easy to cause water splashing, causing pollution of the environment around the equipment and waste of water resources, therefore, the following technical scheme is proposed: As Figures 1 to 6As shown, the stirring blade 302 of the stirring assembly 3 located in the middle of the rinsing bin 1 is rectangular, and a plurality of first water passing holes 305 are arranged on the stirring blade 302. On the one hand, the first water passing holes 305 on the stirring blade 302 can reduce the splash of the stirring blade 302 when stirring, and the rectangular structure of the stirring blade 302 as a whole can increase the area of the stirring blade 302 to press the plastic fragments downward, so that the plastic fragments floating on the water surface are fully pressed into the water for rinsing processing, thereby improving the rinsing efficiency of the device on the plastic fragments.

[0031] In use, the crushed plastic fragments are conveyed into the rinsing bin 1 by the feeding device. The stirring blade 302 of the stirring assembly 3 located near the position is rectangular, and a groove 304 is arranged on the side of the stirring blade 302 away from the stirring rod 301. During the rinsing processing, part of the plastic fragments are accumulated on the water surface due to the surface tension of the water. The groove 304 on the stirring blade 302 can quickly scatter and press the plastic fragments into the water when rotating, so that the plastic fragments quickly contact with the water for rinsing processing.

[0032] The stirring blade 302 of the stirring assembly 3 located in the middle of the rinsing bin 1 is rectangular, and a plurality of first water passing holes 305 are arranged on the stirring blade 302. On the one hand, the first water passing holes 305 on the stirring blade 302 can reduce the splash of the stirring blade 302 when stirring, and the rectangular structure of the stirring blade 302 as a whole can increase the area of the stirring blade 302 to press the plastic fragments downward, so that the plastic fragments floating on the water surface are fully pressed into the water for rinsing processing, thereby improving the rinsing efficiency of the device on the plastic fragments.

[0033] Example Three Based on the rinsing device for PET bottle recycling plastic processing in the above example two, if the plastic fragments floating on the water surface are discharged through the overflow mode through the top discharge port 5 after the rinsing of the plastic fragments in the middle of the rinsing bin 1 is completed, the efficiency is slow, and a large amount of plastic fragments in the rinsing bin 1 are easily accumulated, thereby affecting the rinsing efficiency of the plastic fragments. After the stirring assembly 3 is arranged at the position of the top discharge port 5, the rotation of the stirring blade 302 can assist the discharge of the plastic fragments floating on the water surface, but the water is also pushed out. As the rinsing processing proceeds, water needs to be constantly supplemented in the rinsing bin 1, which increases the cost. Therefore, the following technical scheme is proposed: As Figures 1 to 8As shown, the stirring blade 302 close to the top layer discharge port 5 is rectangular, and the stirring blade 302 is curved outwardly from the stirring rod 301, and a plurality of second water passing holes 306 are arranged on the stirring blade 302, and the stirring blade 302 is elastic, and when the stirring blade 302 rotates, it cooperates with the internal slope of the rinsing bin 1, and the plastic pieces floating on the water surface in the rinsing bin 1 are pushed, and because the stirring blade 302 is curved and elastic, the plastic pieces between the stirring blade 302 and the internal slope of the rinsing bin 1 are extruded to reduce the water remaining in the plastic pieces, and then when the stirring blade 302 rotates and does not contact the internal slope of the rinsing bin 1, the plastic pieces after extruding water are pushed to the top layer discharge port 5 by the elasticity of the stirring blade 302, and then the plastic pieces floating on the water surface in the rinsing bin 1 are discharged, and in the process of discharging, the waste of water in the rinsing bin 1 is reduced.

[0034] In the use process of the present application, the crushed plastic pieces are conveyed into the rinsing bin 1 by the feeding device, the stirring blade 302 of the stirring assembly 3 close to the position is rectangular, and the side away from the stirring rod 301 of the stirring blade 302 is provided with a groove 304, and in the process of rinsing processing, part of the plastic pieces are accumulated on the water surface due to the surface tension of water, and the groove 304 on the stirring blade 302 can quickly scatter the plastic pieces and press them into the water when rotating, so that the plastic pieces quickly contact with water for rinsing processing of the plastic pieces.

[0035] The stirring blade 302 of the stirring assembly 3 located in the middle of the rinsing bin 1 is rectangular, and a plurality of first water passing holes 305 are arranged on the stirring blade 302, which can reduce the splashing of the stirring blade 302 when stirring, and the overall rectangular structure of the stirring blade 302 can increase the area of the stirring blade 302 to press the plastic pieces, so that the plastic pieces floating on the water surface are fully pressed into the water for rinsing processing, thereby improving the rinsing efficiency of the device on the plastic pieces.

[0036] When the plastic pieces on the upper layer of the water surface in the rinsing bin 1 are discharged, the stirring blade 302 of the stirring assembly 3 close to the top layer discharge port 5 rotates and cooperates with the internal slope of the rinsing bin 1, which pushes the plastic pieces floating on the water surface in the rinsing bin 1, and because the stirring blade 302 is curved and elastic, the plastic pieces between the stirring blade 302 and the internal slope of the rinsing bin 1 are extruded to reduce the water remaining in the plastic pieces, and then when the stirring blade 302 rotates and does not contact the internal slope of the rinsing bin 1, the plastic pieces after extruding water are pushed to the top layer discharge port 5 by the elasticity of the stirring blade 302, and then the plastic pieces floating on the water surface in the rinsing bin 1 are discharged, and in the process of discharging, the waste of water in the rinsing bin 1 is reduced.

[0037] The main function realized by the present application is that: by setting different forms of stirring blades 302 in the stirring assembly 3, the stirring blades 302 near the discharging area of the feeding device can quickly scatter and press the plastic fragments into water when rotating, so that the plastic fragments are quickly in contact with water for rinsing processing of the plastic fragments, the first water passing holes 305 on the stirring blades 302 in the middle part of the rinsing bin 1 can reduce the splashing of water when the stirring blades 302 are stirring, and the overall rectangular structure of the stirring blades 302 can increase the area of the plastic fragments pressed by the stirring blades 302, so that the plastic fragments floating on the water surface are fully pressed into the water for rinsing processing, the stirring blades 302 near the top discharge port 5 cooperate with the inclined surface inside the rinsing bin 1 to squeeze out the water in the plastic fragments and push the plastic fragments to the top discharge port 5 to assist in discharging, thereby reducing the waste of water in the rinsing bin 1.

[0038] The installation mode, connection mode or setting mode of the rinsing equipment for PET bottle recycling plastic processing of the present application are all common mechanical modes, as long as the beneficial effects can be achieved.
