Technical Field

[0001] This utility model relates to the field of recycled plastic pellet production technology, and in particular to a flame-retardant plastic pellet cleaning device. Background Technology

[0002] To conserve resources and improve the utilization rate of waste plastic buckets, waste plastic buckets are usually crushed into plastic pellets after recycling. The crushed plastic pellets are then washed to remove dirt and impurities so that they can be reused.

[0003] A plastic granule cleaning device, disclosed in CN223159723U, includes a friction cleaning mechanism for primary cleaning of plastic granules, the friction cleaning mechanism having a discharge port, and a second cleaning mechanism connected to the discharge port for secondary cleaning of plastic granules. This device can efficiently clean dirt and impurities from the surface of the plastic granules. Currently, existing plastic granule cleaning devices typically require workers to lift the material bags containing the plastic granules and pour them into the feeding hopper on a workbench. However, because the inlet of the cleaning device is at a certain height, for large quantities of plastic granules, workers need to lift multiple material bags continuously, which is time-consuming, labor-intensive, and affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that when a large number of plastic granules need to be processed, workers need to continuously lift multiple material bags, which is time-consuming, labor-intensive, and affects work efficiency. The invention provides a flame-retardant plastic granule cleaning device that automatically pushes the material to a high-level feeding hopper through the lifting and pushing components in the feeding cylinder, thereby achieving automated feeding.

[0005] To achieve the above objectives, this utility model provides a flame-retardant plastic granule cleaning device, including a cleaning tank, a feeding hopper at the top of the cleaning tank, a feeding mechanism at the feeding end of the feeding hopper, a discharging mechanism at the bottom of the cleaning tank, a liquid inlet pipe at the top of the cleaning tank, and a liquid outlet pipe at the bottom of the cleaning tank; the feeding mechanism includes a storage frame, a storage hopper inside the storage frame, a discharge end of the storage hopper connected to a feeding cylinder, a lifting component inside the feeding cylinder, and a pushing component on one side of the feeding end of the feeding cylinder.

[0010] As a further description of the above technical solution: scraper plates are connected to both ends of the drive plate.

[0011] As a further description of the above technical solution: the cleaning box is mounted on a support frame, and a control box is provided on one side of the support frame.

[0012] As a further description of the above technical solution: the cleaning tank is conical.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] This invention features a feeding mechanism that directly connects to the feeding hopper, allowing materials to enter the cleaning tank precisely. This avoids the spillage and waste associated with traditional manual dumping.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-4As shown, the present invention discloses a flame-retardant plastic granule cleaning device, comprising a cleaning tank 1, a feeding hopper 2 above the cleaning tank 1, a feeding mechanism 3 at the feeding end of the feeding hopper 2, a discharging mechanism 4 at the bottom of the cleaning tank 1, a liquid inlet pipe 5 at the top of the cleaning tank 1, and a liquid outlet pipe 6 at the bottom of the cleaning tank 1; the feeding mechanism 3 includes a storage frame 31, a storage hopper 32 inside the storage frame 31, the discharge end of the storage hopper 32 being connected to a feeding cylinder 33, a lifting component 34 inside the feeding cylinder 33, and a pushing component 35 on one side of the feeding end of the feeding cylinder 33.

[0025] In the technical solution of this utility model, the feeding mechanism 3 directly connects to the feeding hopper 2, allowing materials to accurately enter the cleaning tank 1, avoiding material spillage and waste during traditional manual pouring. Cleaning liquid can be conveniently added via the liquid inlet pipe 5 at the top of the cleaning tank 1, and wastewater can be easily discharged via the drain pipe 6 at the bottom. Combined with the subsequent discharge mechanism 4, a closed-loop process of feeding, cleaning, liquid discharge, and material discharge is formed, reducing manual intervention in each stage and improving overall operational efficiency. A large amount of material can be temporarily stored via the storage frame 31, and material is collected in conjunction with the internal storage hopper 32 before being fed through the feeding cylinder 33. The lifting component 34 and the pushing component 35 inside automatically push the material to the high-level feeding hopper 2, which is suitable for large-scale continuous operation and avoids interruptions caused by frequent manual feeding. The feeding mechanism 3 realizes automated feeding, and the staff can directly pour the plastic granules in the material bag into the low-level storage box 31 without lifting, which greatly reduces physical labor consumption. The pushing component 35 can smoothly push the material output from the storage hopper 32 into the feeding cylinder 33, and the lifting component 34 then conveys the material upward to the feeding hopper 2, which is suitable for flame-retardant plastic granules of different particle sizes and reduces the risk of material jamming.

[0026] Specifically, the washing tank 1 is cone-shaped. The cone shape of the washing tank 1 helps the material to gather at the bottom, which, together with the stirring and subsequent discharge, reduces dead corners and further improves the washing efficiency.

[0027] like Figure 1 and Figure 2 As shown, the lifting assembly 34 includes a lifting screw 341, on which lifting blades 342 are connected. One end of the lifting screw 341 is connected to a lifting motor 343. When the lifting motor 343 works, it can drive the lifting screw 341 to rotate, and the lifting screw 341 drives the lifting blades 342 to push plastic particles into the feeding hopper 2.

[0028] like Figure 1 and Figure 2As shown, the feeding assembly 35 includes a feeding screw 351, with feeding blades 352 connected to the feeding screw 351. One end of the feeding screw 351 is connected to the feeding motor 353. When the feeding motor 353 operates, it can drive the feeding screw 351 to rotate, which in turn drives the feeding blades 352 to push the plastic granules in the storage hopper 32 to the feeding end of the feeding cylinder 33, thus avoiding material blockage in the storage hopper 32 and affecting the feeding efficiency.

[0029] like Figure 1 and Figure 4 As shown, the discharge mechanism 4 includes a discharge cylinder 41, which is connected to the discharge end of the cleaning tank 1. A discharge screw 42 is installed inside the discharge cylinder 41, and discharge blades 43 are connected to the discharge screw 42. One end of the discharge screw 42 is connected to the discharge motor 44. When the discharge motor 44 works, it can drive the discharge screw 42 in the discharge cylinder 41 to work, which drives the discharge blades 43 to push the cleaned plastic particles upward and discharge them, thereby speeding up the discharge efficiency.

[0030] like Figure 1 and Figure 2 As shown, a drive plate 7 is installed inside the cleaning tank 1. The upper end of the drive plate 7 is connected to the drive motor 8, and a stirring rod 9 is connected to the lower part of the drive plate 7. The drive plate 7 inside the cleaning tank 1 is driven by the drive motor 8, and the stirring rod 9 connected below can fully stir the particles to ensure that the particles are in uniform contact with the cleaning liquid and improve the thoroughness of cleaning.

[0031] Specifically, scraper plates 10 are connected to both ends of the drive plate 7; the scraper plates 10 at both ends of the drive plate 7 can scrape off the particles attached to the inner wall of the cleaning tank, avoid material residue, and ensure consistent cleaning effect.

[0032] like Figure 1 As shown, the cleaning box 1 is mounted on the support frame 11, and a control box 12 is provided on one side of the support frame 11; the cleaning box 1 can be installed and fixed through the support frame 11, and the device can be controlled to work through the control box 12.

[0033] Working principle: The material can be accurately put into the cleaning tank 1 through the feeding mechanism 3 directly connected to the feeding hopper 2, avoiding the waste of material spillage when manually pouring. The cleaning liquid can be conveniently added through the liquid addition pipe 5 at the top of the cleaning tank 1, and the drain pipe 6 at the bottom can easily discharge sewage. Combined with the subsequent discharge mechanism 4, a closed-loop process of feeding, cleaning, liquid discharge and material discharge is formed, reducing manual intervention in each link and improving the overall operation efficiency.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model.
