Description

Technical Field

[0001] This utility model relates to the field of paper dust recycling technology, and in particular to a paper dust recycling device. Background Technology

[0002] Waste paper recycling refers to the process of collecting, sorting, and processing waste paper to make it a usable raw material for papermaking again. This process not only helps reduce deforestation and conserve resources, but also reduces environmental pollution from landfill and incineration, making it an important link in achieving a circular economy and sustainable development.

[0003] Existing recycling devices typically use a compression assembly to compress waste paper before proceeding with subsequent recycling. However, the paper to be recycled often contains paper dust and relatively large pieces of paper or cardboard. These larger pieces may have additional uses, and directly compressing and recycling them makes the process of converting them into pulp more difficult, hindering the recycling process. Therefore, an improved paper dust recycling device is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a paper dust recycling device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

The screening cylinder provides an installation platform for the screening components, providing space for waste paper screening. A feed hopper is installed at the top of the screening cylinder, allowing workers to easily add waste paper to be screened.

[0009] Preferably, in any of the above embodiments, the guide cylinder includes a conical portion whose top end is fixedly connected to the screening cylinder and a rectangular portion fixedly connected to the bottom of the conical portion.

[0010] The above technical solution employs a guide cylinder as a flow channel for the screened paper dust, allowing it to fall into the extrusion cylinder. A conical section is provided at the top of the guide cylinder to facilitate the collection of paper dust flowing from various points within the screening cylinder, while a rectangular section is provided at the bottom of the guide cylinder to facilitate the installation of the extrusion cylinder and the exhaust fan.

[0011] Preferably, in any of the above embodiments, the extrusion cylinder is arranged obliquely, the feeding screw assembly is rotatably connected to a spiral disc inside the screening cylinder, and a motor is arranged outside the screening cylinder and capable of driving the spiral disc to rotate.

[0012] The above technical solution involves an inclined extrusion cylinder, allowing paper dust falling into it to flow towards the collection box under gravity. The waste paper to be recycled is placed inside a screening cylinder, where a feeding screw assembly drives the waste paper screw to move. During this movement, the paper dust flows through the filter cylinder to the guide cylinder, while the relatively large paper and paperboard are pushed out of the screening cylinder by the feeding screw assembly.

[0013] Preferably, as described in any of the above embodiments, the end of the extrusion cylinder is provided with a rectangular insertion frame, and the collection box is inserted into the insertion frame.

The collection box is installed via a plug-in connection, facilitating its removal and placement.

[0015] Preferably, in any of the above embodiments, a pull handle is fixedly connected to the outside of the collection box, and a filter box is provided between the exhaust fan and the guide cylinder.

[0016] The above technical solution employs the following: a pull handle is installed on the outside of the collection box for easy operation by staff. An exhaust fan is installed on the side of the guide cylinder, which drives airflow, allowing paper dust to move more smoothly into the guide cylinder and extrusion cylinder. A filter box is installed between the exhaust fan and the guide cylinder, providing installation space for a fine filter.

[0017] Preferably, in any of the above embodiments, the fine filter screen is inserted into the filter screen box, and the extrusion screw assembly includes an extrusion screw assembly rotatably connected inside the extrusion cylinder and a motor disposed outside the extrusion cylinder that can drive the extrusion screw assembly to rotate.

[0018] The above technical solution employs a fine filter screen to block paper dust, preventing it from being drawn out by the exhaust fan. The fine filter screen is inserted into a filter box for easy removal and cleaning.
