[0005] The utility model aims to provide a device for removing impurities from PET bottle flakes.

[0006] The technical problem solved by the utility model is that in the process of removing impurities from PET bottle flakes, the existing equipment directly blows the dust out of the equipment, causing the blown dust to float everywhere, thereby easily polluting the working environment of the staff.

[0007] The utility model can be implemented through the following technical scheme: a PET bottle flake impurity removal device comprises a debris removal box, a dust suction mechanism is arranged at the bottom end of the debris removal box, the dust suction mechanism comprises a dust suction fan fixed to the bottom end of the debris removal box, the dust discharge end of the dust suction fan is connected with the inner cavity of the collection box at the bottom end of the debris removal box, a dust suction funnel for receiving dust is fixedly installed between the two inner side walls of the debris removal box, the dust suction funnel is connected with the dust suction end of the dust suction fan, a screening drum is rotatably connected to the inner cavity of the debris removal box and located above the dust suction funnel, and the opening of the screening drum corresponds to the feeding hopper at the top of the debris removal box.

[0008] A further technical improvement of the utility model is that the impurity removal box includes a cover plate floatingly connected thereto, the screening drum is rotatably connected to the bottom end of the cover plate, and the feed hopper is fixedly connected to the center of the top end of the cover plate.

[0011] A further technical improvement of the utility model is that the bottom end of one side of the screening cylinder is fixedly connected with a discharge pipe, and a control valve is arranged on the discharge pipe, so that the discharge of PET bottle flakes in the screening cylinder can be conveniently controlled by the arrangement of the control valve.

[0012] A further technical improvement of the utility model is that a filter plate is fixedly installed on the top of the dust suction funnel cavity, and the setting of the filter plate prevents larger solid particles in the impurities from clogging the dust suction fan; a soft cleaning brush abutting against the filter plate is fixedly installed on the bottom end of the screening cylinder, and the screening cylinder is driven to clean the filter plate by rotating the screening cylinder, thereby facilitating extending the service life of the filter plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model puts the PET bottle flakes to be removed of impurities into the inner cavity of the screening drum through the feed hopper, and after the putting is completed, the positioning pin on one side of the sealing plate is pulled out to release the limit of the sealing plate, so that the sealing plate can cover the feed hopper, thereby preventing the dust from flying around when the PET bottle flakes are removed, and then the PET bottle flakes in the screening drum are driven to rotate synchronously by the rotation of the rotating rod. When the rotating rod rotates, the stirring paddle group is driven to further stir the PET bottle flakes in the screening drum, thereby facilitating the speed of the PET bottle flakes impurity removal work. During the rotation of the screening drum, the impurities in the PET bottle flakes are thrown out through the screening holes in the screening drum by the action of centrifugal force, and the impurities thrown out are conveniently collected uniformly by the drive of the dust suction fan, thereby further preventing the impurities screened from flying around, thereby facilitating the improvement of the working environment of the staff and facilitating use.

[0016] 2. After the impurities in the PET bottle flakes are removed, the cover plate can be moved up by extending the electric telescopic rod, and the screening cylinder can be exposed by moving the cover plate up. The PET bottle flakes after impurities removal can be discharged by manually controlling the control valve on the feed hopper. After discharge, the iron-containing impurities can be discharged by disconnecting the power supply of the electromagnetic rod, which makes it convenient for the staff to unload the flakes, thereby meeting the different usage needs of the staff.

[0033] A stirring paddle group 33 is fixedly installed on the outer peripheral wall of the rotating rod 31 and located in the inner cavity of the screening cylinder 32 , and an electromagnetic rod 331 is embedded and installed on one side of the stirring paddle in the stirring paddle group 33 .

[0034] The opening of the screening drum 32 corresponds to the feed hopper 310 , and a sealing plate 311 for closing the feed hopper 310 is vertically elastically slidably connected to one side of the L-shaped support plate 38 , and the sealing plate 311 and the L-shaped support plate 38 are fixed by a positioning pin 312 .

[0035] To be more specific, when the sealing plate 311 is fixed to the L-shaped support plate 38 by the positioning pin 312, the connecting spring used to support the sliding of the L-shaped support plate 38 is in a stretched state. When the positioning pin 312 is removed, the connecting spring returns to its original state, and the sealing plate 311 can cover the feed hopper 310 through the elastic action of the connecting spring.
