Description

Technical Field

[0001] This utility model relates to the field of plastic particle impurity removal and screening technology, and in particular to a plastic particle processing impurity removal and screening device. Background Technology

[0002] In the production of plastic granules, a granulator is required. The granulation process is as follows: after being melted at high temperature in an extruder, the plastic strip is extruded to form a plastic bar. After being cooled, the plastic bar enters the granulator and is cut into plastic granules. Since some of the finished granules are not the size required for use during the granulation process, a screening device is needed to screen the plastic granules.

[0003] In addition, ferromagnetic impurities are often mixed in during the reprocessing of plastic particles, so it is necessary to remove impurities from the plastic particles. According to the search, patent application number 202222904354.1 discloses a plastic particle hopper that can screen and remove impurities. It is divided into upper and lower shells, which can be disassembled by positioning posts and slots to facilitate internal cleaning and maintenance. The upper shell is provided with a material receiving chamber. When the energized coil is turned on, an electromagnet is formed to attract the iron filings mixed in with the plastic particles. Both the upper and lower shells are provided with filter plates to screen the target plastic particles, which is convenient to use.

[0004] However, the impurity removal structure of the screenable plastic granule hopper in the aforementioned public documents is located in a localized area, resulting in poor impurity removal. In addition, the screening path is short, and the plastic granules move to the discharge port before they can be screened, leading to poor screening results.

[0005] Therefore, it is necessary to provide a screening device for removing impurities in plastic pellet processing to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a purification and screening device for processing plastic granules, which solves the problems in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a purification and screening device for plastic granule processing, comprising a device body, a guide pipe movably installed inside the device body, an inner cylinder extending through one end of the guide pipe, a conical frame extending through the circumference of the inner cylinder, and first filter holes formed on the surfaces of the inner cylinder and the conical frame. A drive motor is mounted on the outer surface of the device body, a drive gear is provided at the output end of the drive motor, a driven gear is provided on the circumference of the guide pipe, and the driven gear meshes with the drive gear. A filter cylinder is provided inside the device body, and a stirring rod is provided on the circumference of the inner cylinder. The device is constructed by configuring the inner cylinder, guide pipe, conical frame, drive gear, driven gear, and drive motor. The combined use of the machine, filter cylinder, and stirring rod facilitates multi-stage impurity removal and screening of plastic granules. During operation, the operator feeds the plastic granules into the inner cylinder through the feed hopper, then starts the drive motor. The drive motor, through the driven gear and the driving gear, drives the guide pipe and the inner cylinder to rotate. The inner cylinder first screens the plastic granules, and the conical frame design expands the screening area and improves the screening efficiency. The granules then pass through the inner cylinder into the filter cylinder, where the stirring rod further screens the granules. Finally, they are discharged through the first discharge port, the second discharge port, and the third discharge port, respectively. This method is simple to operate and facilitates the screening of plastic granules.

[0008] Preferably, a base is provided below the device body, a support leg is vertically mounted on the bottom surface of the base, and a mounting seat is mounted on the bottom surface of the device body. The mounting seat is movably connected to the support leg via a pin. An electric push rod is vertically mounted on the top surface of the base, and a top block is provided at the output end of the electric push rod. By using the mounting seat, support leg, electric push rod, and top block in coordination, after the device body has finished working, the electric push rod is activated, causing the electric push rod to drive the device body upward through the top block, thereby tilting the device body and facilitating the discharge of plastic particles and impurities inside the device body.

[0009] Preferably, multiple stirring rods are provided, and the multiple stirring rods are installed at equal intervals on the circumferential side of the inner cylinder. By providing stirring rods, the efficiency of screening plastic particles can be improved.

[0010] Preferably, a feeding hopper is installed on the surface of the device body. The feeding hopper is movably connected to the device body and the inner cylinder respectively through sealed bearings. By setting the feeding hopper, it is convenient to feed the plastic granules that need to be processed and screened.

[0011] Preferably, the device body has a first discharge port and a second discharge port on its surface, and a third discharge port is provided at one end of the guide tube. By setting the first discharge port, the second discharge port and the second discharge port, it is convenient to discharge the plastic particles or impurities inside each chamber after the filtration and screening are completed.

[0012] Preferably, the base is provided with casters at the bottom, and multiple casters are provided. The multiple casters are installed at equal intervals at the four corners of the bottom of the base. By providing casters, it is convenient to move the device body and to operate it.

[0013] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.

[0014] Compared with related technologies, the impurity removal and screening device for plastic granule processing provided by this utility model has the following beneficial effects:

[0015] Compared with existing technologies, this plastic granule processing impurity removal and screening device, through the coordinated use of an inner cylinder, guide pipe, conical frame, driving gear, driven gear, drive motor, filter cylinder, and stirring rod, facilitates multi-stage impurity removal and screening of plastic granules. During operation, the operator feeds the plastic granules into the inner cylinder through the feed hopper, then starts the drive motor, which drives the guide pipe and inner cylinder to rotate via the driven and driving gears. The inner cylinder then screens the plastic granules. Furthermore, the conical frame expands the screening area and improves the screening efficiency. After the particles pass through the inner cylinder, they enter the filter cylinder. Then, the stirring rod further filters the particles inside the filter cylinder. Finally, they are discharged through the first discharge port, the second discharge port, and the third discharge port, respectively. This method is simple to operate and facilitates the screening of plastic particles. By using the mounting base, support legs, electric push rod, and top block in combination, after the main body of the device has finished working, the electric push rod is activated, causing the electric push rod to drive the main body of the device upward through the top block, thereby tilting the main body of the device and facilitating the discharge of plastic particles and impurities inside the main body of the device.
