In addition, the structure has a poor filtering effect on impurities in waste plastics and the filter plate is prone to clogging. Therefore, professionals in this field provide a waste plastic impurity filter to solve the above-mentioned problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4In the utility model, a waste plastic impurity filter comprises a filter box 1 and a feed hopper 2 installed on the top thereof. Two crushing motors 3 are fixedly installed on the right side of the filter box 1. The output shaft of the crushing motor 3 penetrates and extends to the inside of the filter box 1. A crushing roller 4 is fixedly installed on the output shaft of the crushing motor 3. A circular groove 5 is opened on the inner wall of the filter box 1. A drum 6 is rotatably connected inside the circular groove 5. A driving motor 7 is fixedly installed on the back of the filter box 1. The output shaft of the driving motor 7 penetrates the filter box 1 and is fixedly connected to the back of the drum 6. A guide hopper 8 is fixedly connected to the inner wall of the circular groove 5. The guide hopper 8 penetrates and extends to the front of the filter box 1. A scraper 9 is fixedly connected to the bucket 8, uniformly distributed magnet strips 10 are fixedly installed on the inner wall of the drum 6, an inlet 11 connected to the interior of the drum 6 is provided, through grooves 12 are provided at the top and bottom of the circular groove 5, a filter plate 13 is slidably connected to the inner wall of the filter box 1, a vibration motor 14 is fixedly installed at the bottom of the filter plate 13, a uniformly distributed spring 15 is fixedly connected to the top of the filter plate 13, and the top of the spring 15 is fixedly connected to the inner wall of the filter box 1, a movable groove 16 is provided on the left side of the filter box 1, the left side of the filter plate 13 passes through the movable groove 16 and extends to the left side of the filter box 1, and an impurity discharge groove 17 is provided on the right side of the filter box 1.

[0024] A mounting plate 22 is fixedly connected to the inner wall of the circular groove 5 , and the outer ring of the mounting plate 22 is slidably connected to the inner wall of the drum 6 .

[0025] The user puts the waste plastic into the filter box 1 through the top feed hopper 2. The waste plastic is between the two groups of crushing rollers 4. The two groups of crushing motors 3 drive the two groups of crushing rollers 4 to crush the waste plastic, so that the plastic is crushed into small particles and the metal attached to the plastic is separated from the impurities. Then the waste enters the top groove 12 along the inclined inner wall. At this time, the driving motor 7 is driving the drum 6 to rotate inside the circular groove 5. When the inlet 11 rotates to connect with the top groove 12, the waste enters the drum 6 and quickly falls to the bottom of the drum 6. At this time, as the drum 6 rotates, the magnet strip 10 moves to the bottom of the waste so that the metal in the waste is attracted and attached to the magnet strip 10. The drum 6 continues to rotate the magnet strip 10 to drive the metal to move up, and there are continuous magnet strips 10 to the bottom of the waste. The waste is flipped at the bottom of the drum 6. The internal metal is constantly attached. During the rotation of the drum 6, the metal attached to the magnet strip 10 contacts the scraper 9 at the top. The scraper 9 blocks the metal. As the magnet strip 10 continues to rotate, the metal is separated from the magnet strip 10 and then falls into the guide hopper 8 and is discharged from the filter box 1. As the drum 6 rotates, the inlet 11 rotates to the through groove 12 at the bottom. At this time, the waste is discharged downward and falls on the top of the filter plate 13. The unqualified plastic waste and impurities will penetrate the filter plate 13 and be discharged along the impurity discharge groove 17. Driven by the vibration motor 14, the spring 15 makes the filter plate 13 vibrate, and the plastic on the top is discharged to the left along the movable groove 16. During the operation, the user can continuously add waste plastic to the filter box 1 for processing, and the continuous rotation of the inlet 11 can achieve uniform and equal processing.

[0026] In the utility model, by setting a rotating drum 6 and an inlet 11, the crushed waste plastics can be processed at a uniform speed and in equal amounts, and the metals in the waste plastics can be quickly filtered and collected inside the drum 6, thereby improving resource utilization and the quality of subsequent waste plastic processing. The automatic discharge reduces the number of human operation steps and improves the processing efficiency. At the same time, a vibrating filter plate 13 is set to filter the waste plastics, so that impurities in the waste plastics are separated from small particles of plastic and discharged separately for subsequent processing.

[0027] See also Figure 1 , wherein: a control panel 18 is fixedly installed on the front of the filter box 1 , and the vibration motor 14 , the drive motor 7 and the crushing motor 3 are all electrically connected to the control panel 18 .

[0028] In the present invention, the setting of the control panel 18 allows the user to operate the device more simply and quickly, thereby reducing the steps required for the user to operate and improving the processing efficiency of waste plastics.

[0029] See also Figure 4, wherein: a vibration motor 19 is fixedly installed at the bottom of the guide hopper 8 , and the vibration motor 19 is electrically connected to the control panel 18 .

[0030] In the utility model, the driving of the vibration motor 2 19 can make the guide hopper 8 vibrate, thereby preventing a large amount of metal from falling inside the guide hopper 8 and causing excessive friction and inability to move, thereby causing blockage.

[0031] See also Figure 2 , wherein: a baffle 20 is fixedly connected to the bottom of the filter plate 13 , and the baffle 20 is located on the right side of the movable groove 16 .

[0032] In the utility model, when the filter plate 13 moves, the baffle plate 20 will also move accordingly, and the baffle plate 20 always shields the movable groove 16 to prevent impurities and plastics that penetrate the filter plate 13 from being discharged through the movable groove 16.

[0033] See also Figure 1 , wherein: a cover plate 21 is hinged on the top of the feed hopper 2, and a handle is connected to the cover plate 21.

[0034] In the utility model, the cover plate 21 can shield and protect the feed hopper 2 when not in use, thereby preventing dust and debris from entering the filter box 1 and affecting the subsequent treatment quality of waste plastics.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
