Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a crushing and drying device for recycling plastic products. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of synthetic polymer materials with malleability.

[0003] Plastic products are now used in various fields, but due to their non-biodegradability, excessive use, and inadequate recycling, they cause serious energy and resource waste and environmental pollution. With increasing environmental awareness, the secondary recycling of plastic products has become an important means of addressing environmental pollution. Traditional plastic recycling involves three steps: washing, crushing, and drying. Existing plastic recycling stations typically wash collected plastic waste with water guns, then let it air dry before crushing it. This process is time-consuming, wasteful of water resources, and inefficient.

[0004] Therefore, it is necessary to design a high-efficiency crushing and drying device for recycling plastic products, addressing the shortcomings of existing technologies. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a plastic product recycling device that can successively clean, crush, and dry plastic products, and also realize the secondary utilization of water resources.

[0006] The technical solution is as follows: A crushing and drying device for recycling plastic products includes a dryer, a crusher, and a cleaning mechanism; the feed end of the crusher is connected to the cleaning mechanism, and the discharge end is connected to the dryer; the dryer includes a drying chamber and a conveyor; the drying chamber includes a bottom plate, long side plates and short side plates vertically arranged on both sides of the bottom plate, and a top plate arranged on the top of the long side plates and short side plates; a water collection box is provided on the upper side of the short side plate; a fixed baffle is provided on the side of the drying chamber near the crusher, and a heat-insulating observation curtain is provided on the other side; an upper partition plate parallel to the bottom plate is provided inside the drying chamber; drying elements are respectively provided on the bottom plate and the upper partition plate; the conveyor plate passes through the drying chamber and is located between the upper partition plate and the bottom plate.

[0007] Optionally, a guide channel is provided on the lower side of the top plate, and the guide channel is arranged at an angle.

[0008] Optionally, the bottom of the water collection box is inclined at different heights, with a water outlet at the lower end.

[0009] Optionally, a cooling pipe is installed on the upper side of the top plate.

[0010] Optionally, the cleaning mechanism includes a housing, a circulation pump disposed on the top of the housing, a water storage tank disposed on the bottom of the housing, and a packing conveyor disposed inside the housing; the top of the housing is provided with a flushing nozzle facing downwards; the water inlet of the circulation pump is connected to the water storage tank, and the water outlet is connected to the flushing nozzle.

[0011] Optionally, the water collection box and the water storage tank are connected by a pipeline.

[0012] Optionally, the drying oven adopts a sandwich design.

[0013] This utility model adopts a sequentially connected arrangement of a cleaning mechanism, a crusher, and a dryer. Plastic products are sequentially cleaned, crushed, and dried by this device. The device can also condense and recover the water vapor evaporated during the drying process and return it to the cleaning mechanism, thus realizing the reuse of water resources.

[0014] The drying oven adopts a sandwich design for better heat preservation. The top plate of the drying oven is equipped with a guide channel at the bottom, which facilitates the flow of steam to the water collection box. The bottom of the water collection box is designed with an inclination, so that the water in the water collection box flows back to the water storage tank by its own weight. The discharge side of the drying oven is equipped with a heat preservation observation curtain, which can not only keep the oven warm but also facilitate the observation of the internal conditions of the oven.
