Description

Technical Field

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

[0002] Plastic production refers to the production of high molecular weight compounds from synthetic resins through addition or condensation polymerization. A wide variety of plastic products are produced, such as plastic bearings, plugs, ball cages, and copper pipe flanges. The plastic production process involves using raw materials and requires the operation of a plastic raw material drying device to dry these materials.

[0003] A search revealed a patent document with publication number CN221066902U disclosing a drying device for raw materials used in plastic parts production. The device includes a drying chamber, a reciprocating conveying drying mechanism, and an auxiliary drying mechanism. A feeding pipe is fixedly connected to the drying chamber. The reciprocating conveying drying mechanism is located inside the drying chamber and includes multiple sets of conveyor belts and a reverse conveyor belt. Limiting blocks are provided on both sides of the conveyor belts and the reverse conveyor belt. The auxiliary drying mechanism is located between the conveyor belts and the feeding pipe. The auxiliary drying mechanism includes a closed baffle, with a telescopic support rod hinged below the closed baffle, and a material-releasing rake on one side of the closed baffle. Through the arrangement of these mechanisms, the device can continuously convey and dry raw materials such as plastic granules used in plastic parts production. The reciprocating conveying of multiple sets of conveyor belts allows for multi-level drying of the plastic granules, improving the continuity and drying effect of the drying process.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The above-mentioned raw material drying device for plastic parts production includes a feeding pipe fixedly connected to the drying chamber for conveying the plastic granules to be dried into the drying chamber for drying. An exhaust gas guide pipe is connected to the drying chamber to exhaust the humid, hot air inside the drying chamber. A discharge pipe is connected to the bottom of the drying chamber to discharge the dried plastic granules. A drying airflow conveying pipe is connected to the bottom of the drying chamber, connecting the heating element and the drying chamber, allowing the hot air from the heating element to be conveyed into the drying chamber along the drying airflow conveying pipe. This facilitates the drying of plastic granules conveyed on multiple sets of conveyor belts and reverse conveyor belts. A heating component is fixedly connected to the end of the drying airflow conveyor pipe away from the drying chamber. The heating component heats the gas generated during the operation of the blower. A blower is connected above the heating component. The drying airflow is generated by controlling the operation of the blower. However, the plastic raw materials are stationary relative to the conveyor belt during the movement, which makes the flowability of the plastic raw materials poor and may even cause the plastic raw materials to accumulate. This results in uneven heating of the plastic materials and affects the drying efficiency and quality of the plastic raw materials.

[0006] 2. In the aforementioned drying device for raw materials used in plastic parts production, a reciprocating conveying drying mechanism is installed inside the drying chamber. This reciprocating conveying drying mechanism allows for continuous drying of the plastic granules, thereby improving the efficiency of the drying device. An auxiliary drying mechanism is located between the conveyor belt and the feeding pipe. This auxiliary drying mechanism includes a sealing baffle that matches the feeding pipe and is rotatably connected to a limiting block. The rotation of the sealing baffle controls the feeding pipe, reducing the risk of heat loss from the drying chamber along the feeding pipe. However, this method is inconvenient for sorting the plastic raw materials by size and for crushing large-volume plastic raw materials, resulting in inconsistent sizes of the dried plastic raw materials. This reduces the fineness of the raw materials and may even require separate operation of screening and crushing equipment for sorting and crushing the dried plastic raw materials.

[0007] To address these issues, we provide a drying apparatus for plastic production. Utility Model Content

[0008] The purpose of this utility model is to provide a drying device for plastic production.

Furthermore, a filter component is set up to sort the plastic raw materials inside the drying drum according to size, and a rotating crushing blade crushes large-volume plastic raw materials, making the dried and discharged plastic raw materials finer. This solves the technical problems mentioned in the background art of a raw material drying device for plastic parts production.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
