[0003] After searching, the prior art CN222022001U discloses a waste separation device for plastic products, comprising a box body, wherein a feed hopper is provided inside the box body. The waste separation device for plastic products, through the coordinated arrangement of a feed hopper, a guide plate and a collection box, collects crushed plastic particles through the feed hopper during use, and the plastic particles are fixedly dropped into a conveying channel by a feed blade. The falling plastic particles are then detected by a metal detection device and the detection information is sent to a control panel. The control panel then controls a baffle plate to conduct metal-containing plastic particles into a first discharge hopper, so that the plastic particles can be transported by an electromagnetic conveyor belt while the metal particles are adsorbed on the conveyor belt. The metal particles are then scraped off by a scraper baffle plate and stored in a collection box, thereby achieving a rapid separation of the plastic particles from metal impurities and facilitating subsequent recycling and processing.

After installation, the magnetic rod 113 is located in the filter cover 108, and the vibration component is arranged at the bottom of the screen 105. The corresponding perforated fixing ears on the screening box 102 and the sealing plate 103 are fixed by bolts respectively. After the sealing plate 103 is opened, the unfiltered plastic parts on the upper side of the screen 105 can be cleaned. The mounting frame 104 is fixed by bolts and is provided with a cable hole for the cable of the vibrator 119 to pass through. The vibrator 119 is located on the inner side of the screening box 102 and is provided with a movable amount to avoid the cable from breaking when the screen 105 vibrates vertically. The water tank 106 is fixed to the base by bolts, and the power distribution cabinet of the equipment is provided on the right side of the base, and a water spray pipe 114 is provided. The fixing plate of the water spray pipe 114 is fixed by bolts, and the water inlet is connected to the external clean water pipeline through a movable water hose. A rotating support shaft is provided at the bottom of the gear disc frame 107, and a shaft is installed at the bottom of the water tank 106 The support seat and the rotating support shaft are installed on the bearing seat to realize rotation through the rotating bearing.

The stepped external thread end of the top mounting end of the magnetic rod 113 passes through the through hole on the cross plate 112 and is fixed by a nut.

[0026] Secondly, the feeding pipe 115 is welded to the top sealing cover of the crushing box 101, and the cutting member is arranged on one side of the crushing box 101. The feeding pipe 115 is used to feed waste into the crushing box 101, and the cutting member is used to crush plastic parts.

[0027] The cutting motor 116 is then mounted on the top sealing cover of the crushing box 101. The rotating shaft 117 is connected to the output shaft of the cutting motor 116 via a coupling. Multiple crushing blades 118 are welded vertically to the rotating shaft 117 at regular intervals. The cutting motor 116 is secured with bolts, and its output shaft is connected to the rotating shaft 117 via a coupling. The crushing blades 118 are welded to the rotating shaft 117.

The vibrator 119 is fixed to the bottom of the fixed frame of the screen 105 by bolts, and can directly adopt existing technology, such as the equipment disclosed in the prior art CN214021862U. As those skilled in the art are familiar with, the working principles and wiring methods of the vibrator 119, the waterproof motor 110, and the cutting motor 116 are commonplace, and they all belong to conventional means or common knowledge. They will not be repeated here. Those skilled in the art can make any selection according to their needs or convenience. The spring component 120 includes a T-shaped rod and a spring. After the T-shaped rod slides through the through hole on the limit ear on the screening box 102, the external thread end is connected to the threaded hole at the bottom of the fixed frame of the screen 105, and the spring is sleeved on the outside of the T-shaped rod and abuts the fixed frame and the limit ear respectively. After the vibrator 119 is in operation, the screen 105 can be moved back and forth vertically and vibrated with the cooperation of the spring component 120, so as to screen the broken plastic parts.

[0029] When the present invention is used to solve the problem that the existing device cannot remove the mud and sand on the surface of the plastic waste after crushing and screening the plastic waste, which affects the secondary utilization of the plastic waste, the plastic waste is first put into the crushing box 101 during processing, and is crushed by the crushing assembly and then falls into the screening box 102. The screening box 102, the screen 105 and the vibrating component cooperate to perform screening. Then, the plastic particles that can pass through the screen 105 fall into the filter cover 108. Further, the waterproof motor 110 is controlled to operate, which will drive the drive gear 111 to rotate, and finally the gear disc frame 107 is rotated, so that the filter cover 108 can be rotated. After the rotation, clean water is sprayed into the filter cover 108 through the water spray pipe 114, and then the plastic parts can be cleaned. Finally, the sewage is discharged by opening the discharge valve on the water tank 106. The magnetic rod 113 can adsorb the iron impurities in the plastic parts. When the filter cover 108 is subsequently removed, the clean water delivery is stopped first, and then the cross plate 112 is removed, and the magnetic rod 113 is removed for cleaning. After further removing the T-shaped pull rod on the lifting ear of the filter cover 108, the cleaned plastic parts can be taken out, thereby solving the problem that the existing device cannot remove the mud and sand on the surface of the plastic waste after crushing and screening the plastic waste, affecting the secondary utilization of the plastic waste.
