Description

Technical Field

[0001] This utility model belongs to the technical field of plastic impurity removal equipment, and in particular, it is a impurity removal device for the production of recycled plastic pellets. Background Technology

[0002] Recycled plastic pellets are a type of material that is recycled from waste plastic products through various physical processes. Because recycled plastics contain various impurities during the recycling process, they need to be cleaned. However, existing recycling plastic cleaning devices use a screening method, which is ineffective due to dust adhering to the surface of the plastic pellets, making them impractical.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221775018U) entitled "A Removal Device for Recycled Plastic Granule Production," which includes a removal box, a feed hopper fixedly mounted on the top of the removal box, a feed pipe fixedly mounted on the top of the feed hopper, the feed pipe, the feed hopper, and the removal box being interconnected, and a discharge port fixedly mounted on the bottom of the removal box, with a solenoid valve fixedly mounted at the bottom of the discharge port. This device solves the problem of existing devices being inconvenient to disassemble and clean. However, during use, it still has the problem of not being able to clean the dust on the surface of the produced plastic granules, resulting in incomplete removal of impurities and reducing the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to provide a purification device for the production of recycled plastic pellets, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for the production of recycled plastic granules, comprising a box body, the interior of which is provided with water for dust removal, and the end of the box body is provided with a discharge port for easy discharge of cleaned plastic granules. Two symmetrically arranged linear motors are installed on the top of the box body, and the moving parts of the two linear motors are welded with moving plates that slide with the top of the box body. A connecting plate is welded to the opposite side of the moving plate, and a circular plate is movably connected to the bottom of the connecting plate. A long plate is rotatably connected to the bottom of the circular plate, and a cleaning plate is detachably connected to the bottom of the long plate. The cleaning plate abuts against the plastic granules fed into the box body.

[0006] As a preferred embodiment, the top of the connecting plate is screwed with an electrically adjustable telescopic rod, and the moving part of the telescopic rod passes through the top of the connecting plate and is fixed to the circular plate.

[0007] As a preferred embodiment, two straight rods are also fixed to the top of the circular plate. The side walls of the two straight rods are slidably connected to the connecting plate, and the two straight rods are symmetrically arranged with the fixing part of the telescopic rod.

[0008] As a preferred embodiment, a drive motor that provides power is installed inside the circular plate, and the output shaft of the drive motor passes through the bottom of the circular plate and is fixed to the top of the long plate.

[0009] As a preferred embodiment, the bottom of the circular plate is also provided with an annular slide rail surrounding the output shaft of the drive motor. The slide rail is slidably connected to two symmetrical sliders. A connecting rod is welded to the top of the slider, and the other end of the connecting rod is fixed to the top of the long plate.

[0010] As a preferred embodiment, four fixing plates are welded to the side wall of the box, and a hydraulic rod is welded to the top of each fixing plate. The moving part of the hydraulic rod is welded to the bottom of the hollow fixing frame.

[0011] As a preferred embodiment, a parallel linear motor is installed on the inner wall of the fixed frame. The moving part of the linear motor is fixed with a mounting plate. The top of the mounting plate is screwed with an electric actuator capable of multi-stage extension and retraction. The moving part of the electric actuator passes through the mounting plate and is fixed to the horizontal plate.

[0012] As a preferred embodiment, a magnet is installed at the bottom of the horizontal plate, and the side wall of the horizontal plate is slidably connected to the bottom wall of the box. Two round rods are also fixed at the top of the horizontal plate, and the side walls of the two round rods are slidably connected to the mounting plate.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This impurity removal device for recycled plastic pellet production uses a linear motor to drive a long plate to move inside a housing. Under the action of the drive motor and an electrically controlled telescopic rod, the long plate moves vertically inside the housing, stirring the plastic pellets mixed with water inside the housing. This mixes the attached impurities and dust with the water, resulting in better dust removal of the plastic pellets and improving the practicality of the device.

[0015] This impurity removal device for recycled plastic pellet production addresses the issue that plastic pellets typically contain dust, metal, and other impurities. To separate the metal from these impurities, a hydraulic rod is controlled to move a fixed frame at the top of the housing. This, combined with a linear motor and multi-stage telescopic electric actuators, adjusts the position of the horizontal plate. The horizontal plate then slides against the inner bottom wall of the housing, connecting the magnet at the bottom of the plate to the metal. This process also prevents solids from accumulating in the water during prolonged use, facilitates cleaning of the inner wall of the housing, and allows for recycling, further enhancing the device's ease of use.

[0016] This device solves the problem that existing equipment cannot clean the dust adhering to the surface of plastic particles, thus improving the device's practicality. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] A purification device for the production of recycled plastic pellets, such as Figures 1 to 4 As shown,

[0028] include:

[0029] The tank 1 contains water for dust removal. The water can be added directly from the top of the tank 1 or injected through a filling pipe on one side of the tank 1. The end of the tank 1 has a discharge port for easy discharge of cleaned plastic granules. The discharge port facilitates the discharge of cleaned plastic granules and controls the water level inside the tank 1. A through-type drain pipe with a valve is installed on the inner bottom wall of the tank 1. The drain pipe can periodically tilt the water inside the tank 1 and help to treat impurities mixed in the water.

[0030] Two symmetrically arranged linear motors 3 are installed on the top of the housing 1. The moving parts of the two linear motors 3 are welded with a sliding plate 8 that slides with the top of the housing 1. A connecting plate 12 is welded to the opposite side of the sliding plate 8. A circular plate 9 is movably connected to the bottom of the connecting plate 12. An electrically adjustable telescopic rod 10 is screwed to the top of the connecting plate 12. The moving part of the telescopic rod 10 passes through the top of the connecting plate 12 and is fixed to the top of the circular plate 9. In order to maintain the structural stability of the circular plate 9, two straight rods 11 with smooth outer circumferences are also fixed to the top of the circular plate 9. The sidewalls of the straight rods 11 are slidably connected to the connecting plate 12. The two straight rods 11 are symmetrically arranged relative to the telescopic rod 10. The arrangement of the telescopic rod 10 and the straight rods 11 makes the circular plate 9 more stable when it moves at the bottom of the connecting plate 12.

[0031] A long plate 13 is rotatably connected to the bottom of a circular plate 9. A drive motor 18 that provides power is installed inside the circular plate 9. The output shaft of the drive motor 18 passes through the top of the circular plate 9 and is fixed to the top of the long plate 13. Two connecting rods 20 are welded to the top of the long plate 13. The other end of the connecting rods 20 is welded to a slider 21. A slide rail 17 is slidably connected to the slider 21. The slide rail 17 is located at the bottom of the circular plate 9 and surrounds the output shaft of the drive motor 18. By controlling the rotation of the output shaft of the drive motor 18, the long plate 13 is made to rotate stably under the action of the slide rail 17 and the slider 21.

[0032] A cleaning plate 19 is detachably connected to the bottom of the long plate 13. The cleaning plate 19 comes into contact with the plastic particles put into the box 1. Under the combined action of the linear motor 3, the telescopic rod 10 and the drive motor 18, the cleaning plate 19 and the long plate 13 can fully mix the plastic particles inside the water body with the water body, thus completing the cleaning and dust removal of the plastic particles.

[0033] Four fixing plates 2 are welded to the side wall of the housing 1. A hydraulic rod 4 is connected to the top of the fixing plate 2. A fixing frame 6 is connected to the moving part of the hydraulic rod 4. Two parallel linear motors 5 are installed inside the fixing frame 6. A mounting plate 15 is welded to the moving part of the two linear motors 5. A multi-stage telescopic electric push rod 16 is screwed to the top of the mounting plate 15. The moving part of the electric push rod 16 passes through the mounting plate 15 and is connected to the horizontal plate 14. Two round rods 7 are also fixed to the top of the horizontal plate 14. The side walls of the two round rods 7 are slidably connected to the mounting plate 15, and the two round rods 7 are symmetrically arranged relative to the electric push rod 16.

[0034] To facilitate the separation of metals and other impurities carried by plastic particles, a magnet is installed inside the horizontal plate 14. Under the action of the linear motor 5, the electric push rod 16, and the hydraulic rod 4, the horizontal plate 14 slides against the inner bottom wall of the tank 1 to separate the sediment. In conjunction with the horizontal plate 14, it prevents a large amount of sediment from accumulating on the inner bottom and inner side walls of the tank 1 after long-term use, thus facilitating water circulation and cleaning.

[0035] Since the aforementioned mechanical structures are in a humid environment for a long time, they are treated for moisture and corrosion prevention, and are regularly inspected and replaced to ensure the normal operation of the device.

[0036] Furthermore, when linear motor 5 and linear motor 3 move, their moving parts move in a staggered manner to avoid mutual interference and influence.

[0037] The linear motor 3, hydraulic rod 4, linear motor 5, electrically adjustable telescopic rod 10, electric push rod 16, and drive motor 18 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0038] Working principle

[0039] When using this impurity removal device for the production of recycled plastic pellets, water is first added into the tank 1, and then the plastic pellets to be processed are placed into the tank 1. At this time, the moving part of the linear motor 3 is controlled to move, which drives the connected connecting plate 12 to move. Under the action of the telescopic rod 10 and the straight rod 11, the connected circular plate 9 is moved. In conjunction with the drive motor 18 installed inside the circular plate 9, the movement of the long plate 13 and the cleaning plate 19 connected to the long plate 13 is completed, so that the plastic pellets are fully in contact with the water.

[0040] Then, the moving part of the hydraulic rod 4 is controlled to retract, driving the fixed frame 6 to move downward. At the same time, the moving part of the linear motor 3 is controlled to be located on one side of the top of the box 1. Then, the moving part of the linear motor 5 is controlled to drive the mounting plate 15 to move. At the same time, the moving part of the electric push rod 16 is operated to extend. Under the action of the round rod 7, the horizontal plate 14 with magnets is moved inside the box 1, completing the separation of impurities deposited inside the box 1. This avoids the deposits from accumulating for a long time and being difficult to clean. The box 1 and the horizontal plate 14 can be cleaned periodically to separate the metal.
